"No, I just wanna go home, Sarah!”

"Come on, Ben,” I said, grabbing my younger brother’s arm.  He could be such a brat sometimes.  At least I was still stronger than him, but not for long.  He was almost 14 and growing fast.  He was still short, but he was filling out like a football player.  Or maybe a wrestler.  If I weren’t in volleyball, I’m sure he could already overpower me, even though I’m four years older.

"A magic shop!?” he whined.  "This is stupid.”

I pulled him inside anyway, ignoring his dramatic tone.  This is why he doesn’t have any friends at school anymore.  I still don’t know what happened to my sweet baby brother, but a year or two ago, he just seemed to snap, and hate anything and everything.  Our parents were pissed...his grades dropped and he was getting in fights at school.

"I’m only going to check inside for a minute, Ben,” I sighed.

"Whatever,” he replied, though he stayed inside the shop as I began to look around.  At first I thought he was being bullied at school, and I wanted to help him.  But that wasn’t it at all.  A few months of calls to our parents made it clear...

Ben was the bully.

He was the one picking fights, driving away his friends.  He never even spoke to Derek anymore, our next door neighbor.  They’d been friends since second grade...until Ben hit puberty.  I don’t know what Ben said, but the little brat had turned viciously on Derek about four months ago, and they hadn’t spoken since.

Whatever, I thought.  God, is he rubbing off on me?  At least I would be heading off to college in a year.  Then he’d be our parents’ problem.  Until then, I had to walk him home.

The magic shop was pretty silly.  A lot of dusty shelves with stupid knickknacks.  I was hoping for something that actually worked.  I walked straight up to the counter, since I knew Ben would go ballistic if I wasted time.  "Hello?” I asked.

What’s there to stop me from grabbing something and leaving?  I wondered, amazed that no one was at the front desk.  But I heard footsteps immediately when I asked.

"Good afternoon,” a middle-aged woman, maybe 25, said, wearing a muumuu, her hair up like a librarian, wearing hideous little glasses.  Very unflattering...clearly I’d come to the wrong place.

"Do you have any face creams?  I want something to look younger...my skin smoother.”

"Younger?  How old are you?” the woman asked, impolitely.

"Seventeen.”

She shook her head, but pointed toward the front of the store.  Together, we walked to a shelf with all sorts of ‘magical’ beauty creams, bumping into Ben on the way over.  I just know he intentionally shoved me, but I wasn’t about to make a scene in the middle of the magic shop.

Madam Ruth (she introduced herself shortly into the conversation) explained the purpose of all the creams, but I had to stop her when she said that "Beauty Cream #8” would change your features to match whatever movie star you were thinking about when you apply it.

"Bullshit,” I said.  "I’m not going to waste my money on ‘snake oil’.  C’mon Ben, we’re leaving.”

Madam Ruth sighed, but didn’t try to stop me.  She just said, "Thank you...please come again.”

I rolled my eyes.  I just wanted something that would actually work.  I thought the ‘magic’ claim was exaggeration, not fraud.  I held the door open for Ben, and for some reason, he was grinning ear to ear.

* * * * *

I slammed the door shut so that Sarah wouldn’t see or hear what I was doing.  That nosy cunt!

I flipped open my laptop, reflexively opening up a video of two chicks going at it.  I wasn’t really paying attention this time, though.  Instead, I pulled out a small bottle, and a piece of paper I’d stolen from the stupid-ass magic shop.

"That shopkeeper is fucking blind,” I said to myself, sure that Sarah wouldn’t overhear me when I was in my room with music playing.  My sister was such a bitch.  But at least it wouldn’t matter long.  She’d be off to college and the whole fucking house would be in my control.  Our parents are as retarded as Madam Ruth.

Neither had seen me sneak downstairs behind the counter.  There were old workbenches down there, and a little bottle with a handwritten piece of paper beside it.  I took both immediately.  Ugly bitch doesn’t deserve to keep her things if she’s that blind.

I was up and out of there before Sarah finally realized the old broad was a crackpot, the bottle tucked neatly away.  I held it in my hands now, watching the thin bits of sunlight flicker off the glass.  It was corked, and the inside looked like water.  Probably was water too.  Magic is such a scam.

I unfolded the paper.  On one side, in big, block letters, it said, "NOT FOR SALE.”  Then, in cursive that took me a minute to puzzle out, it said, "Priscilla, this means you.”

Flipping it over, I read in the same hand-writing:

    Love Potion #10
    Notes: Adjustments must be made before sale.  Too much wisproot and wolfsbane allows the potion to act on people against their will.  I suspected extra magnesium would counteract; instead, it made the effects linger indefinitely.  Perhaps human hair or skin cells might limit possible targets?  The accidental success of LP#9 makes me wonder if dumping the amarant would create a true ‘transformation potion’, without the...unfortunate side-effects.

    Summary of effect: Ingest a small amount.  Upon observation of next living creature, regardless of gender/species, subject will transform into the most appropriate form and appearance to begin a romantic relationship.  (Animals apparently have a single-minded view of ‘romance’.)  To avoid misuse, ensure that the first living creature seen is the intended target.

How weird.  The potion had to be a scam, but these notes weren’t advertisements or anything.  These were written by the creator of the potion, and treating it all seriously.  Perhaps the old nutter really believed it would work!

My mind kept dwelling on one, peculiar sentence: Animals apparently have a very single-minded view of ‘romance’.

I laughed.  Immediately I thought of Derek.  That fucking dog-fucker.  Everyone in school knew Derek fucked dogs except Derek.  Rumors were so powerful.  But if this potion worked like it said it did, then he really would be a dog-fucker.

Worth a shot, I figured.

* * * * *

"Derek, it’s your turn to let the dogs out,” Zack yelled from the living room, where he was playing Assassin’s Creed 3.

I sighed.  He was right, technically.  I yelled back, "But I covered for you yesterday...”

"Oh yah.  I’ll do it after this mission...”

My twelve-year-old brother didn’t tend to think things through.  He never stopped after ‘one more mission’.  Sure, he’d have to clean up with the dogs peed on the floor, but I’d have to mix up the Oxyclean.  My parents didn’t want Zack messing around with that stuff.

Fine, I thought.  I went to the door, and suddenly the sleeping German Shepherds were up and bouncing around, tails wagging furiously.  Pancakes, smaller and more athletic, leapt at the door so frantically he almost fell over.  Beefstick was larger and stronger, his gruff, low bark enough to show his impatience.

Yeah, I know.  Pancakes and Beefstick?  Don’t look at me.  Our parents let Zack name them.  Five years ago, when he was seven.  He’d immediately blurted out his two favorite foods, but Dad vetoed "Pizza”.  But his third favorite food, beefsticks; that was okay?  Not even a day had passed before my best friend (at the time), Ben, had made a dick joke.

He wasn’t the only one to make jokes, either.  My parents got the dogs because Dad wanted to go into amateur dog-breeding for the police force.  He was an officer himself, not satisfied with the stock the precinct was getting.  Not wanting to deal with puppies, he found the best, male dogs he could get.  Sometimes they’d take the dogs out to stud...sometimes the bitches would be delivered to our backyard.

As a growing pre-teen, you cannot imagine the embarrassment I suffered when the breeding was in my own backyard.  Especially when they wanted Beefstick.  The larger German Shepherd was the choice pick for guard dogs and drug-sniffers, and the men who wanted those things always seemed a lot more...vulgar.  They seemed to delight in referring to ‘his beefstick’ and making me blush.  And then Ben would give me shit for days, even though he always seemed to watch the breedings from his backyard.  Eventually I started to hide in my room when we had ‘guests’ over.

Ben never let it drop, but for the week of the breeding he was absolutely the worst.  "Watched another quick porking?” he’d say.  Or, "Bet you wish you were that bitch, gaywad.”  His language would have gotten him smacked in my house, but from what I saw, even at ten he talked that way around his own parents.  I laughed politely, but it never seemed that funny.  Besides, he was the one that always watched the breedings.

Still, I thought it was friendly ribbing...until the rumors at school started to fly.  No one really knew my parents were dog-breeders until that fateful week in seventh grade.  Then, suddenly everyone seemed to know we had two, intact German Shepherds.  Their names, apparently, were Beefstick and "Humper”.  And, to my surprise, I apparently liked getting fucked by them.

"Where did you hear that?” I had asked, face red.

"Ohhhh!  He’s not denying it!” they had replied.

Eventually, they did tell me, though.  Ben.  My own friend!  He didn’t deny saying it when I confronted him in the hallway, but acted like what he’d said was still true!  That’s when my name around school changed to "Dog-Fucker Derek”.  At least when a teacher wasn’t around.  Then, the kids liked to make barking sounds while giggling to each other.  I just blushed and tried to ignore them like my parents said, but two years had passed and the mocking hadn’t stopped.

I still had friends, at least, though definitely not Ben.  The nerds and outcasts picked me up easily enough, and I’d probably have ended up with them by high school anyway.  I did far too well in school and far too badly in sports to be a jock.  Unlike Zack.  He was in basketball, and he was already a black belt in Taekwondo.

Sometimes I really wished Dad hadn’t gotten into dog-breeding.  But I knew better than to blame him, or the dogs.  It was Ben’s fault, and my former friend didn’t even seem to regret what he’d done, even though he didn’t seem to have any friends, anymore.  He was always around, like a nagging fly, and the other kids all laughed when he swore and mocked other students, but I never saw him hang out with anyone anymore.  I don’t know what happened to him...but, despite myself, in some ways, I pitied him.

I opened the door, and the dogs burst through into the yard.  It was about 10 square feet, with a tall, wooden fence around three of the sides.  The fourth side, shared with Ben’s yard, was only four feet tall, and had a chain-link gate, installed shortly after we first moved into the neighborhood, and it was clear that Ben and I had hit it off.  We were friends from first grade, all the way to seventh.  I walked outside, taking a deep breath as Pancakes and Beefstick did their business.

And...there was Ben, standing at the fence.  He must have come outside when I did.  I rolled my eyes, waiting for him to say something like, "Don’t mind me, go ahead and let them fuck you!”

Today, however, he didn’t say that.  He didn’t even have his trademark sneer on his face.  When I looked at him, he looked away, and said, "Hey, Derek...”

I paused, then realized my mouth was hanging open.  "What?”

"Look,” he said, meeting my eyes.  What was that expression?  "I just wanted to say...I’m sorry.”

BULL...SHIT.  He does not get to ruin my life for two years and then apologize and expect me to forgive him.  "Well, great, Ben.  Thanks so much.  Go to hell.”

Ben cringed.  I’ve never seen him cringe before.  What was his game?  He said, "Yeah, I know.  I don’t expect you to forgive me.  I was awful...I know that now.  Here,” he said, offering a small bottle.

I looked it over.  It was a twelve-ounce bottle of Gatorade Ice.  I blinked, taking it purely from surprise.  "What?”

"Just...you know, a peace offering.”

A bottle of Gatorade.  One of the little ones.  To repay me for making the whole school call me "dog-fucker” to my face.  I laughed, not knowing what else to do.  What on Earth?

Ben said, "Sorry, again,” turning and walking back to his house.

I stood there, stunned, as the door closed and I was left alone.  Could this be real?  Was he really trying to apologize by giving me a seventy-cent bottle of...watermelon flavored Gatorade?  Ben had always been pretty strange.  I wouldn’t put it past him.

I sighed, realizing I’d been holding my breath.

I patted Pancakes on the head, and he took off in circles around the yard, hoping I would chase him.  I chuckled and said, "It’s too hot for that.”

Beefstick, however, was more than happy to sit next to me as ran my fingers through the thick fur around his neck.  He always made me think of those huge bodybuilders in the magazines at the grocery store, with necks larger than their heads.  Finding a collar for him had taken multiple tries; he had a bad habit of pulling backwards away from me when walking, and the first two collars had slipped right off.  The third collar was just barely too tight.  Fourth time was a charm.

I walked over to the dog toy bucket to get a ball for Pancakes, who was still shooting around the yard like a maniac.  Did Zack forget to walk the dogs before school?  I reached in, past the unused collars, and grabbed a nice, soft, plastic ball.  Suddenly, both dog’s eyes were glued to my hand, watching its every motion.

With a smile, I threw the ball straight between the two German Shepherds.  Pancakes skittered across the ground, getting there first, but Beefstick barreled into him, and the dogs forgot all about me.  Pancakes darted away with the ball, chased by the larger, slower dog.  I leaned against the fence to watch as the dogs exercised each other.

A drop of sweat hit my eyebrow, and I swiped it away.  Of course, it was only 3:30.  Mr. Bennett said it was hottest after noon, because the sun’s rays had more time to heat everything up.  Made sense to me.  The Gatorade, however, was cold.

Why not? I wondered.  The drink may be a weird, insufficient apology, but it was a cold drink on a hot day.  I twisted off the cap, which spun off after a satisfying amount of resistance.  I put it to my lips, the sweet, cold liquid pouring into me.

Pretty good flavor, actually.  I normally only liked orange-flavored drinks, but this was a good approximation of watermelon.  It even had a citrusy aftertaste.  Oof...  It also had a bitter one.  I quickly took another drink to replace the bitterness with the sweet corn syrup.

Except for the weird aftertaste, it was a very satisfying drink.  I gulped down the twelve ounces in just four drinks, tossing the bottle into our recycling bin.  Sure enough, as soon as my hand moved to throw the bottle, Pancakes was there.  He abandoned the ball to Beefstick, hoping to jump and grab the plastic container before it was gone.  He was fast, that’s true, but he missed.

I laughed, petting the disappointed dog.  "Good hustle!” I praised, using the same, oft-repeated phrase Mrs. Tiller yelled at us in gym class.  Pancakes just cocked his head, staring at me with his dark, black eyes.

That’s when I felt it.

It started with an itch, but the rash spread quickly.  One minute I was scratching my arm absent-mindedly, the next I was trying to scratch more itches than I had hands for.

"What the?” I asked out loud, looking down at my arms.  My arms were hairier than ever.  Was I just noticing that?  Was I going through puberty, or what?  My voice had already changed...  Then I caught the motion.  The hair was growing...even as I watched!  My blonde hair grew thicker, longer, and darker, taking on a bright, brown color.

That wasn’t the only thing happening.  My butt suddenly hurt...bad.  "Owwww!” I said reflexively, looking around, frantically for help.  When I glance into Ben’s yard, he was at the door, his face white as he walked forward.  "Help me!” I cried, holding out a hand toward the fourteen-year-old.  The hair on the back of my hand grew, covering even my fingers.

Ben didn’t say anything, just walked, stunned, to the fence.  I had to do something about my butt.  The pain was getting worse.  Desperately, my hands went to the button on my jeans.  Unbuttoning it helped, but not enough.  Ben was watching, but I didn’t care.  The pain was too much!  I slid my pants and underpants off in one motion, right past my shoes, to my great relief.

The pain was gone!  I twisted to look over my shoulder at the cause, and nearly yelped in surprise.  I... had a tail!  It was bushy, and mostly the same golden brown as the rest of the hair.  Or should I say ‘fur’?  My neck was sprouting as well.  I’d tried to grow a beard a couple weeks back with no success, but this was ridiculous!  My entire face was sprouting dark, black fur!

Ben finally spoke, seeming awestruck.  "It really worked!”

"Ben, what is happening to me!” I shrieked, my voice cracking.  I felt something really weird happening, a tingling down near my belly button.  Oh no!  My eyes shot to my crotch, as did Ben’s.

I didn’t have time to worry about my former friend seeing me naked.  The fur had stopped, at least, before covering my dick.  But that just made it all the easier to see the soft, pink flesh changing before our eyes.  I shrunk, noticeably, a strange crease appearing right down the middle.  My balls were shriveling up and disappearing, though it felt more like that were sliding inside me.

Ben said, "Oh, my god.”

"Ben...” I pleaded, and I didn’t have to try to show the anguish on my face.  I was covered in the strange fur now, some of it black, like my face.  My hands started to feel clumsy, and I realized that beneath all that fur, my fingers were shrinking.  My stomach began to tighten.  But I didn’t care so much about that.  My eyes were stuck on my penis...  No, my vagina.

There, nestled in light, brown fur, stood a puffy, tri-fold vulva, just like a dog.  I was turning into a dog.  A bitch.

My legs gave out, and I collapsed onto all fours next to the fence.  "Ben!” I yelled again, even as my nose started to stretch out in front of my eyes.  I looked up at him.  Was...was he smiling?  Couldn’t he see what was happening to me!?  I was on all fours, wearing only my t-shirt, socks, and shoes.  In the sheer ridiculousness of what was happening, I thought, Well, at least I can still get served at McDonald’s in this outfit.

That’s when I felt it.  Something wet and slippery between my legs.  I gasped, looking over my shoulder, to see Pancakes, his snout up between my legs, lapping eagerly at my new equipment.  I’d seen him do that plenty of times before, but I wasn’t a dog!  My arms and legs were still human, give or take.  Not for long, I suspected.

Ben started laughing.

Laughing.

"It really worked!” he said again.  "Now be a good girl and let ‘Humper’ do his thing.”

This...was...his...doing!?  I gasped.  The Gatorade!  It was the only explanation that made any sense.  He’d put something in it, a potion or something.  But magic isn’t real!  Except...I have pretty good evidence to the contrary.

Pancakes didn’t care about my inner monologue.  He didn’t care that I didn’t look exactly like a dog, either, or that I was wearing clothing.  He lapped eagerly at my puffy mound, letting his tongue slip inside.  Beefstick was coming over too, looking more tentative about my odd behavior.

I yelped.  His huge, wet tongue felt...really good, actually.  I whimpered and spread my back legs, trembling as he shoved his tongue deeper.  Oh, God, yes! I thought.  "Oh, god, no!” I yelped, looking up at the chuckling Ben.  What was I doing?  I needed help, fast, and it was clear that that motherfucker wasn’t going to do anything.  I was losing precious time letting Pancakes slurp at me.  Already I could feel my legs shifting and changing, my nose moving farther and farther away from my eyes.

"Zack!!!!” I screamed, knowing that he’d hear me.  The game room wasn’t very far from the backyard sunroom, and he didn’t bother wearing headphones when our parents were still at work.  Admittedly, I didn’t want my younger brother to see me, halfway a bitch, getting eaten out by Pancakes.  But it was far better than the alternative.

Only...the sound that came out was more like, "Zzzark!”  It sounded almost like a bark.  I tried again.  "Bark!”

I’d lost my voice.  Suddenly, it dawned on me just how much trouble I was in.  If I fully transformed, what could I do?  Would my brain even remain intact?  My hands, my voice, and possibly even my mind were all at risk - everything that made me human.  If Zack didn’t see me changing, no one but Ben would know what had happened!

Turning, I started barking frantically at the house, getting a temporary reprieve from Pancakes’ tongue.  He followed along behind me, however, quickly refilling me.  I ignored his tongue; I ignored that Ben could now see, at a three-quarters view, my own dog licking my newfound pussy.  All that mattered was getting Zack outside.

Bark!  Bark!  Awoooo!

He’d hear it for sure, but that was no guarantee he would come.  He was supposed to come shut the dogs up when they barked too much.  But he was supposed to walk the dogs in the morning, and he was supposed to let the dogs out every other afternoon.  There were lots of "supposed to”s that seemed to take a backseat to Assassin’s Creed 3.

I tried to ignore the deep licks violating my virgin hole, but it just felt so good.  I kept barking, but I felt like I had no control over my hindquarters, my tail lifted to the side for Pancakes.  It was just like the dozens and dozens of times I’d seen Pancakes or Beefstick in action...which meant...

I am in heat.

I should have realized as soon as Pancakes showed his interest.  Actually, as soon as my puffy, swollen vulva appeared between my legs.  I’d seen so many bitches getting bred, but I never thought I would be one, whimpering in pleasure.  Was I losing my mind?  Even the most skittish, frightened bitches gave in to the dogs eventually.  Please...not my mind.  Hands, voice; anything but that.

It didn’t look good.  I’d stopped barking, spreading my legs wider as I started instinctively to hump up and down against his tongue, much to Ben’s delight.  I didn’t want Pancakes to stop.  How can I be enjoying this!

Ben laughed, "Told you you were a dog-fucker.”

Dog-fucker.  At this rate, he was right.  Pancakes wouldn’t stop until he’d had me.  I tried to will myself to run away, as I’d seen other bitches do, but I couldn’t.  That tongue.  I couldn’t leave it - I didn’t want to.  I have less willpower than some dogs, I realized.

Pancakes pulled his tongue free, and I could move again!  He tried to jump onto my back, but I was too quick, leaping forward.  My feet slipped right out of my shoes, still covered in white socks.  It was done - I was a full dog, a perfect replica of a German Shepherd, just a touch smaller than Pancakes himself.  I didn’t make it far before the socks and shirt constrained my movement so much that Pancakes caught up.

He knew just what to do, jumping onto my back and wrapping his paws firmly around my slender hips.  I yipped, looking over my shoulder in horror.  There, between his legs, his red tip was peeking out, aimed straight for my pussy, and still my tail dangled off, out of the way.

Not like this!  I was a virgin in so many ways I almost laughed.  I’d never had sex, never seen a girl naked, never made out, never had a girlfriend (obviously, considering the rumors), never been kissed.  Hell, the internet filters at home meant I’d never even seen any porn.  Ironically, the closest I’d come to sex before was watching Pancakes and Beefstick in action.

Now I’ll see that first hand.

Ben was watching, enthralled as he watched me getting mounted, still in socks and a t-shirt.  "Good girl, Slutpuppy!  Make me some puppies, okay?”

Something about the way he said "Slutpuppy” made it sound like a name.  I couldn’t really have puppies, could I?  Surely the potion would wear off.  It had to be like prescription drugs, right?  Mr. Carver said every drug wore off after a short time, as the body processed it.  What am I thinking?  Why should science have any impact on magic?

I whimpered, but even if I could have struggled, I knew I wouldn’t break Pancakes’ powerful grip.  None of the other bitches ever had.  Pancakes had an intense expression of concentration as he lined up his glistening tip.  This was it.  I set my legs apart, bracing myself, vulva bouncing up and down.  Blood rushed to my face, but despite my humiliation, I couldn’t look away from his approaching cock.

Dog-fucker, indeed.

I could feel the heat of his loins against my mound before I felt contact.  I whimpered, jaw dropping as the slimy tip poked into my soft flesh.  Pancakes resting his bulging tip against the little, protruding nub at the base of my y-shaped folds until he was certain his aim was true, and then leapt forward, plunging up and into me.

Schlorp!  I yelped as Pancakes penetrated, his full, thick cock ramming deep as his furry sheath collided with my outer lips.  The gate creaked, and I saw Ben walk into the yard, chuckling, kneeling down to watch up close.  I was mortified.  How could that monster do this to me, and then let this happen?  Still, I was helpless to resist as Pancakes filled me up, tugging backward only to pound me again.

His wet cock sliding inside of my rubbed up against something that drove me wild.  The sheer joy that pulsed through my body was impossible to resist, and, with Ben watching only a foot away, I began to hump back eagerly against Pancakes, moaning as my own dog claimed my virginity.

Oh god...he’s in me!  He rolled his hips against me, grunting as I’d heard him do dozens of times before.  He hammered into me like my spreading folds were a nail that only he could drive, though Beefstick was watching intently on the other side from Ben.  Normally, of course, we kept the other dog in the house while a breeding was going on, but Beefstick didn’t challenge for ownership.

No, everyone in the yard knew that I was Pancakes’, at least for now.  Ben marveled at the repetitive schlorps of our hips colliding, laughing as I whimpered and humped.  "Derek, are you even still in there?” he asked, a smirk rising from the corner of his mouth.  "You’re really liking this!”

I couldn’t answer him, but I knew the answer.  If I’d completely lost myself, I wouldn’t feel so dirty, so spoiled.  I had a mix of relief and horror as I realized that I would retain my mind, only to be helpless to resist Ben’s whims.  At least until the magic wore off!

Pancakes let his tongue dangle from his mouth, slobbering on the back of my neck as he thrust contentedly.  He grunted and groaned, just doing what came naturally for him.  Presented with a bitch in heat, of course he would ‘rise’ to the occasion.  He couldn’t know that I was Derek, that I was burning with humiliation.

Ben put one hand on my rump, and one on Pancakes’ knee, pulling us apart so he could see.  The German Shepherd on my back was used to being handled by humans, and didn’t object.  Faster and faster he violated me, driving deep into my warm, clenching vagine.  Every inch of my insides twitched and trembled with unending pleasure, turning my whimpers into one, pathetic, drawn-out whine.  All I could do was pant desperately for breath, tensing my front legs to push back against his thrusts.

And all the while, the true cause of all my problems watched from the sidelines, the boy’s jaw gaping as he watched my puffy folds spread wetly apart again and again for Pancakes’ full, throbbing cock.  Ben said, "Shit, he’s getting bigger!”

I knew what that meant, and I could feel the growing knot as it squeezed painfully between my lips.  But even now, as the point of no-return grew ever nearer, all I could do was whine and hump my hips.  My entire world seemed to have shrunk to a single foot: my clenching cunt, and the massive dick that ravished it.  Why does it have to feel so good!?  I could feel his tip squishing up inside of me, Pancakes expertly hilting himself into me, his bitch, to wait for his knot to swell.

"Fucking hell,” Ben said, as I felt the two glands swelling inside me, stretching my vulva to gross lengths.  I’d see it before, all the other bitches bulging lewdly as they got tied.  Pancakes inflated them (and me) until their pussies looked more like baseballs.  Beefstick, on the other hand, was more like a softball.  Ben had never seen a breeding up close before, judging by the impressed admiration he offered Pancakes.

My mound ached, stretched to its limit.  The tight folds pulled him even closer, dragging him deeper into my burning cunt.  I squeezed and pumped around him, my groans joining his.  If I hadn’t lost hope when my voice had turned to pathetic barks and whimpers, I knew to give up hope now.  Tied deep with Pancakes, I was his until he was finished with me.

"C’mon boy, fill her up!” Ben said, encouragingly.

Encouragement he didn’t need.  I heard the oncoming flood before I felt it, a loud splurt! filling my ears.  His cock twitched and jumped inside of me, spewing seed that splattered against my innermost walls.  He thrust one last time, digging deep, his paw trembling with the effort of holding me beneath him.  Tied as he was, I could feel his pulsing balls where they pressed up between my thighs, pumping ounce after ounce into my virgin womb.

My whines turned to fast, uncontrollable yips as I lost control.  Pancakes’ knot was throbbing inside me, burrowed up against what seemed to be the epicenter of my pleasure.  My measured humping gave way to frantic flailing as I squirmed beneath him, feeling his hot breath wash over the back of my head.  My mouth gaped, tongue spilling out as I drooled uncontrollably.

Oh, god, Pancakes!  I yelped and moaned, rocking my hips as the German Shepherd began short, fast thrusts, each ending with another loud splurt.  I clenched around his humongous cock, and for that brief moment, there was nothing I wanted in the world more than to milk him of every last drop.  Waves of bubbling cum drained into me, pooling in the bottom of my womb.  I jumped and wiggled beneath him, feeling the pool slosh around, absently wondering how I could possibly be enjoying this.

Everything felt so different from when I’d masturbated.  There, I’d been in control.  Here, I was subject to his every whim.  Pancakes decided when to lick me, when to mount me.  Pancakes chose when I was ready for him.  I’d had literally no say in the matter.  All the decisions that had led to this blissful moment, panting beneath him, had been Pancakes’ to make.  I felt a strange euphoria in submitting to my pet dog.

I couldn’t fault his choices either, as predictable as they were.  I whined and moaned until my voice was hoarse, Pancakes squeezing load after load into my burning womb.  If this is what sex feels like...I want more!

Or so I thought at the time.  As with all the other bitches, Pancakes groaned and swiveled off of my back, turning around and tugging roughly on his thick, embedded knot.  He still panted, balls churning, but the fog of intense pleasure wafting in my brain began to clear up.  It felt like I was outside in the winter, and suddenly took off my winter coat.  One second I was whining for more, and the next...

A pleasant feeling radiated through my body, but the good was no match for the bad.  As though I could think clearly, I realized the full extent of what had just happened.  I was a female dog!  Pancakes had raped me, taken my virginity, and filled me up, while I humped and begged for it!  And all the while, the colossal dick that had caused the whole thing had watched, laughing!

My cheeks burned, and I looked away from Ben, horrified that I stood there, my false, tender vulva bulging grossly around Pancakes’ cock.  I flattened my ears instinctively, but I couldn’t tuck my tail between my legs while the German Shepherd was still tied deep.  My canine eyes couldn’t produce tears...or I would have been bawling.  What had happened to me?  Would I ever change back?  What would Ben do now?

He said, "You’re really not in there, anymore, are you Derek?  You’re just a dumb dog.” curiously, looking me over.

I looked him in the eyes.  What would he do if he thought I was gone?  What if he knew I wasn’t?  Nervously, I shook my head back and forth, a very human gesture.

"You’re not!?” he cried, suddenly delighted.  "You enjoyed getting fucked that much?  Well, I guess you’re going to enjoy your new life,” he laughed.

I stared at him, my jaw dropped.  He couldn’t mean to keep me like this!  Not even Ben was that much of a monster.

Ben noted my shock, and smirked, "Hey, don’t look at me, ‘Slutpuppy’.  I didn’t think it would actually work!  But I couldn’t change you back if I wanted to - it’s permanent!”

I whimpered, staring at the young teenager in disbelief.

"Read for yourself,” he said, shrugging, tossing a small piece of paper on the ground in front of me.

Notes: Adjustments must be made before sale.  Too much wisproot and wolfsbane allows the potion to act on people against their will.  I suspected extra magnesium would counteract; instead, it made the effects linger indefinitely.

The effects linger indefinitely.

Indefinitely.

I was speechless, for more than one reason.  I stood stunned, reading the full note twice over, ignoring Ben as he took out his pocketknife, slicing my T-shirt and pulling it off, along with the socks.  I didn’t see at the time, but he must have taken the clothing and tossed it into his yard; the next thing I knew, Ben had taken the smallest extra collar from the toy-bin and clasped it around my neck.

He grabbed the note back and said, "Sorry, Slutpuppy.  Looks like you’re my responsibility now.  You and your puppies.”

I whined desperately at him.  How could he have tested something like that on a real person?  His apologies were empty, mocking laughter at what had happened to me.  What sort of monster was he?  I couldn’t just...be a dog for the rest of my life.  I couldn’t!  There must be some mistake, some magic fix, an antidote...anything!  But even if there were, would Ben bother to find out?  This can’t be happening!

Maybe I wasn’t giving Ben enough credit.  He couldn’t have really believed the potion would work, and he wouldn’t want to have to take care of me for the rest of his life...or, I guess, the rest of mine...  Surely he’d return to wherever he bought the thing and ask for help.  Maybe accidentally transforming his childhood best friend was just the kick in the butt the teenager needed to change courses from delinquent to human being.

Schlurp, schlurp, schlurp!  I winced, suddenly reminded that Pancakes was still tied inside of me as he began to tug sharply.  Groaning, I dug my claws into the grass, pulling too.  I wanted him out of me even more than he did.  Ben just watched, smiling.

After the seventh tug, Pancakes ripped free, my pussy squelching closed, a thin dribble of white dog seed spilling down my thighs.  I shivered, once again feeling dirty and defiled.  I was a fourteen-year-old boy, not just another of Pancakes’ bitches to service.

Strong hands grabbed my collar, pulling me forward.  My eyes flashed in anger at Ben, but he held up a single finger in warning, shaking it back and forth.  "Now, now, Slutpuppy.  No biting, or I’ll find a dog pound that takes care of dangerous animals.”

I growled, but that was all.  He was right, of course; animal control wouldn’t blink twice at taking care of a violent dog.  I let him run his hands through the fur on my neck, testing the collar to make sure it fit.  My face was on fire, but at least Ben couldn’t see my blush beneath my thick fur.  I looked him straight in the eyes, and I could help but whine, begging him to help me.  He didn’t seem to care, suddenly looking past me and smiling.

"Now be a good girl...”

What was he looking at?  I turned my head around, surprised at how flexible my neck was, and dropped my jaw in shock.  Beefstick.  The stocky, muscular German Shepherd was standing right behind me, sniffing at my leaking pussy.  Beneath him, I could see his boner poking out.

Not again!

Immediately, I leapt to get away, but Ben was larger and stronger than me.  His grip on my collar remained firm, holding me in place.  He was going to make me take Beefstick as well!  I thrashed uselessly, but I didn’t have to entertain my hope of escape for long.  Beefstick wasn’t the sort of dog who wasted time on formalities.  He didn’t even sniff me a second time before he jumped up on my back, his weight pressing down on my sore hind legs.

With Beefstick’s front legs wrapped around my waist, Ben let go, backing up to watch.  We both knew there was no way I could escape the big dog until he was done with me.  Whining, I spread my back legs and lifted my tail, my mound bouncing up and down in anticipation.  There was no use in resisting; better just to get it over with.  As much as I hated to admit it, Pancakes had blown my mind.  How could this be any worse?

"Good girl,” Ben said again, as Beefstick humped tentatively, his hot tip searching for its target.  The teenager let his hand drift to his crotch, cupping himself.  Oh, god, he’s getting off to this!

Soon enough, so would I.

His tip brushed up against my tender flesh, and just like that, he rammed his hips forward, hilting his whole, humongous cock into my pre-lubricated passage.  I yelped!  He was far bigger than Pancakes, with the exception of his knot, which had not yet swelled.  But I knew from experience that that too was larger.  Beefstick pumped frantically, his huge, throbbing erection plumbing my deepest depths.  After Pancakes, I was far wetter, so Beefstick’s thrusts echoed with lewd splashing and sloshing.

A low, rumbling growl escaped his throat as he pulled me back, again and again, onto his spear.  My vagina was stretched to its limit around his swollen dick, his bony tip thumping repeatedly against my sore, innermost wall.  My whole body was on fire, and half of that sensation was pain.  I knew now why my parents wouldn’t put Beefstick out to stud with any bitch that weighed 60 pounds or less!  I was probably above that limit, but not by much.

What will happen when his knot swells?

"Derek, Mom and Dad are home!”

Six pairs of eyes went straight to the house, as Ben, Pancakes, and I saw Zack opening the backdoor.  Beefstick was too preoccupied to look.

"Hey!” Zack cried, as he saw what was going on in the yard.  He didn’t know it was me; he couldn’t know.  But still, I swear I could feel his eyes on me.  My twelve-year-old brother was watching me get reamed by our dog.  I didn’t think it was physically possible to get MORE embarrassed!

Ben was quick with a story.  Or maybe he’d planned it?  Either way, he said, "Hey, Zack!” as if grateful for his help.  "My new dog snuck into your yard while I wasn’t looking!”

Zack looked around.  "Where’s Derek?” he asked.

Right here, I thought miserably, getting pounded even while my brother talked to Ben.

Ben just shrugged.  "I don’t know - haven’t seen him all day.”

Zack looked confused, but he just said, "I’ll get Mom and Dad.”

No!  I could only think of one thing worse than having my parents watch me take my second dog of the day, and that involved changing permanently into a bitch.  I barked at Zack, but of course he still left.  Why couldn’t he just go back inside, let Beefstick finish with me, and leave our parents none-the-wiser?

While Zack was telling our parents, Beefstick was doing his duty.  He plunged into me, over and over, making me yip and squeal.  His continuous, low growl was only punctuated by repeated grunts each time he humped.  I whined, beginning to feel his knot swell.  I swear, he must have only been a third of his full size, but already his backward thrusts tugged painfully at my lips.

Dad charged out onto the lawn, huffing and puffing, Mom on his heels.  He immediately took charge, telling Mom, "Get Pancakes back inside.”  She did so immediately.

Then, he turned on Ben, and I swear, even that bully wilted in front of my dad.  "What is going on?  We didn’t authorize this breeding!”

Ben’s jaw dropped, and he said, "It’s...It’s Tinkerbell.  Somehow she got into your yard when I wasn’t looking and -”

Tinkerbell??

"Fuck,” Dad said, with emphasis.  He only swore in the most desperate circumstances.  A second later, my father was crouched beside me, one hand on my rump, the other pulling Beefcakes away as best he could.  As strong as Dad was, he could only pull us a couple inches apart before the dog’s still-swelling bulge got stuck.  Dad was looking there, at my inflated vulva, when he said, "It’s too late; they’re already tied.”

Dad leaned forward, running his hands over my head and neck in what he probably thought was a comforting gesture.  He spoke to me, "It’s okay, girl.  You’re doing great.  Everything will be okay, girl.”

My father petting me and calling me ‘girl’ while I was getting pounded was anything but comforting!

Ben just smiled, which didn’t go over that well with my father.  Dad rounded on him, voice raised and forceful.  "You’ve got to be careful with a bitch in heat, Ben!  There’s nothing I can do now, but there’s a good chance she’s pregnant.  Is Tinkerbell even registered with the AKS?”

"The what?”

They argued about me, almost oblivious that I was standing right between them, putting out for Beefstick.  Honestly, I was relieved that Dad wasn’t watching me anymore, though I saw Mom and Zack watching from the door.  His knot was full-size by now; it had to be.  Yet still I felt him growing, until my pussy threatened to tear.  The discomfort was really nothing compared to the huge, bulbous knot trembling up against my clit.  I blushed, gently rocking my hips, wishing I could just let go and enjoy it, without the audience.  Why can’t I just get fucked in peace!?

"The American Kennel Society.  God, do you even know her dam?”  Ben had a pretty good idea who my mother was.  Dad continued, "You’re going to want to get her spayed as soon as possible, Ben.”

What!?

Ben seemed to get tired of Dad’s harsh tone.  Like the belligerent teenager he was, he said, "Hey, this isn’t my fault!  You say I should be careful, but you left your dogs outside alone!”

Dad looked around the yard, as if suddenly realizing something.  He said, "Where’s Derek?  He’s supposed to be watching them...”

I’m doing more than watching them, Dad.

Ben says, "How should I know?”

Dad frowned.  "Well, you’re right about that.  He’s going to get an earful when he gets back, I promise you that.”

Ben just smiled.  "Don’t worry, I’ll make sure to spay her.”

He wouldn’t really, would he?  Did it even matter?  I was going to be a bitch for the rest of my life!

Dad, however, seemed satisfied, nodding.  "She’s a pretty healthy-looking bitch.”  My father was supposed to be proud of my grades in school, not the luster of my coat and my strong haunches!  "If you can get Tinkerbell registered and her line doesn’t have health problems, you might want to keep her intact.  Good puppies could really help the breed.”

Ben and Dad looked down at me, admiring me.  I was dying inside.  My whole family was watching me panting and humping against Beefstick, and only Ben knew the truth.  His endless smirk burned in my skull.

Still, as humiliated as I was, my hindquarters had a different view.  Beefstick had finally stopped swelling, making me wince.  I knew I’d be bulging out like a softball, but at least the others couldn’t see it, yet.  Tied so deep, his every thrust sent his hefty balls slapping up against my thighs, until finally, as everyone watched, Beefstick launched himself forward and erupted inside me.

Splurt!

His gigantic cock barely fit inside me, his knot throbbing just inside my trembling lips.  Just like with Pancakes, I was helpless to resist the waves of pleasure that racked my small body.  In front of everybody, I whined and moaned, clenching down around him and humping madly to milk him of his seed.  Our tongues dangled out, gasping for breath as drool spilled down.  Again and again he pounded forward, releasing loud, wet spurts into my nubile, fertile womb.  Beefstick knew his job well, breeding me eagerly.

"That’s it, then,” Dad said, having seen enough similar breedings to tell when a stud got his rocks off.  There was a sense of finality to his words that pierced my lust-addled mind.  My father was only suggesting that the deed was done, and I was pregnant or not.  I knew the truth.  The real finality had come when my own family couldn’t recognize me; when they would just watch as Ben decided to lead me away, to start my new life as Tinkerbell.

Or is it ‘Slutpuppy’?

No, I couldn’t give in so easily.  Maybe some opportunity would arise, and I could do something.  The future wasn’t predetermined - I could still change it!  I just had to keep an eye open for the opportunity.

My newfound optimism was sorely tested a minute later, when everything I’d predicted came true.  Zack went back to playing games while Mom started dinner.  Dad watched Beefstick tie with me, waiting the full eleven minutes as the dog continued to squeeze loads of cum into me.  I yelped when Beefstick finally managed to pull his humongous knot free, his seed spilling out and soiling my rump.

Dad held Beefstick’s collar firm, just watching as Ben took mine.  Without even realizing it, Dad was giving me up to Ben, the monster who had done this to me.  I whimpered at my father, but he only heard the whines of a simple bitch being dragged from her mate.

What will my parents do when I don’t come home?  How long before they give up the search, unable and unwilling to see that I was just next door, wearing new fur?

"Good girl, Tinkerbell,” Ben said, grinning ear to ear.  "Don’t worry, I’ll take good care of you.”

I shivered, realizing I had my own problems to worry about.  What will Ben do with me?

Chapter Text

There’s no way our parents were going to let Ben just suddenly have a dog.  Where did he get the money for it?  It didn’t look like a pound dog.  Who’s going to pay for the food?  When did my brother even get it?

I’d only been upstairs for an hour or so, texting Sarah Harding (known in our group as Sarah #2 because she’d moved here after me), when I had heard Ben coming in the house, barely restraining a frightened dog.  It looked like a...what was it...a Great Dane?  Whatever those black and brown police-looking dogs were called, like the neighbors had.  At first I thought he must have stolen one of their dogs, but this one was female.

He said he ran down to the pound and got one, on a whim.  My parents bought that story easily enough, but they said they’d have to "think about” whether to let him keep the dog.  Total bullshit.  I’d asked for a dog when I was his age, and they’d said "no”.  They were afraid it’d mess up the house.  And I, unlike Ben, am responsible.

It was the next morning, a Saturday, and as always, Ben was sleeping in.  I got up early to shower and dry my hair, setting it the right way for the occasion.  For school, I kept it simple, with a ponytail that could last the whole day, but today I was going to meet friends at a party, so I needed to look my best.  I let it fall loosely around my shoulders, combing it until it shined brightly in the light.

I hoped Isaac Laughner would be at the party.  I looked so hot he’d have to notice me.  Sure, as the school’s quarterback, he could pretty much date any girl he wanted, but why not me?

I glided downstairs, practicing my ‘princess walk’.  A princess needed to glide, as if floating across the floor.  Sure, it only really worked with a long skirt, so my jeans didn’t send the right message.  But practice makes perfect, and that’s what I needed to be, tonight.

When I got downstairs, I saw Dad carrying some things into the house.  No...way...  He had a big bag of dry dog food, a blue leash, and a box of little blue plastic bags.

"You are not letting him keep that dog.” I stated.

"Now come on, Sarah,” my father said in his ingratiating tone.  "Ben needs to learn responsibility.  We can’t take away the first thing he’s shown an interest in for years.  This will be good for him.”

"And me having a dog when I was fourteen wouldn’t have been good for me?  This is bullsh - bogus.”

Just behind him, the dog in question was scratching and whining at the door to the backyard.  When I looked back at my Dad, I could see his pleading eyes.  "Oh no,” I said.

He said, holding up the leash and poop bags, "Can you take Tinkerbell for a walk?  I don’t want dog shit all over our backyard, and I’ve gotta run some errands for work, and you know Ben.”

Dog shit.  How charming!  I’d have to remember to wait as long as possible before introducing Isaac to my dad.

I stamped my foot.  "If this is about teaching Ben responsibility, make him do it.”

Dad held his hands palm up, as if helpless, and said, "I promise, we’ll talk to him about what he has to do to keep this dog, tonight.  Just walk him down to the park and back, okay?”

I rolled my eyes, but took the leash and trash bags.  "Her, Dad.  Her name is Tinkerbell...”

The dog whined again, but didn’t scratch at the door.  Dad just smiled, and headed back to his car.  Great, I thought, and even in my head the words dripped with sarcasm, looks like they finally got me that dog I always wanted.





Tinkerbell was pretty obedient.  She’d shied away from the leash when I first put it on her, but now that we were walking down the sidewalk, she stayed right next to me, not pulling on the leash.  The park was only a block away, but I’d hoped she’d ‘do her business’ before then.  I watched her carefully, but she never made a move to do anything.

Actually, she was behaving a little weird.  Granted, I’d never had a dog, but I’d seen them.  Both Jill and Sarah #2 had dogs.  This one, though, wasn’t looking around at all.  In fact, Tinkerbell kept staring at the ground, especially when we passed other people.  I thought I might have to pull her away from other people, but she didn’t just not care about people, she actively avoided them.  Maybe before her stay in the pound, she’d been abused?

"C’mon, girl, do your business!” I said, cheerfully, hoping the tone of my voice would get through to her.

She did look up at me, meeting my eyes, but she almost seemed to shiver.  God, how long am I going to have to be out here waiting for this dog to ‘go’?  Honestly, I couldn’t think of a worse fate than suddenly being saddled with an unwanted dog.

I kept walking, until we finally made it to the park.  It was like half-a-block long and half-a-block wide, filled with tall trees and bushes and things.  I used to go here when I was just a kid, but now, as an adult, there were better things to do.

We walked past the playground toward the trees, but when I got near the first, large bush, Tinkerbell bolted for cover, tugging on the leash.  She was strong, for a dog I could carry in my arms, and pulled me off balance.  She stopped just behind the bush.

"Oh,” I said, laughing.  "A dog with privacy issues.”

I looked away, just waiting, until Tinkerbell returned beside me.  I grabbed the poop bag and started toward the bush, when Tinkerbell whined and pulled back on the leash.  She can’t still be embarrassed, can she?  But her whimpers were insistent whenever I took a step toward the bush, so I shrugged.  No one was looking, so I just tucked the bag in my pocket, and started for home.

I was going to head straight home, but I saw something that stopped me dead in my tracks.  Rather, someone.

Isaac Laughner.

Just as I was leaving the park, he was entering it, leading his own dog.  It looked like a Dalmatian, only a lot bigger than I expected, and with pointy ears.  It was half again as tall as Tinkerbell, and probably weighed more than I did.  I didn’t give the dog a second glance, looking instead at Isaac.

He was perfect.  Tall, muscular, and with light blonde hair which curled up just slightly at the ends.  He walked with confidence, straight-backed, like a prince, not like the thugs most of the other boys tried to imitate.  Especially on the football team.  Every other boy wore saggy pants and swaggered back and forth like their bones were all mush, but not Isaac.

"Hi, Sarah.”

I blinked.  Oh, he’s talking to me!  Hastily, I smiled, and said, "Isaac!  What are you doing here?”

His beautiful forehead crinkled up in confusion.  "Um...walking the dog, I guess.  Nice dog you got there, I always liked German Shepherds.”

"What?” I asked, trying to process his words.  "Oh, yeah, Tinkerbell!  Yeah, German Shepherds all the way.”

God, I sound so stupid!  Focus Sarah, focus!

Isaac knelt down in front of me, and I almost panicked, until I realized he was just petting his dog.  "Don’t worry, Samson, I like Great Danes, too.”

So that’s what a Great Dane looks like.  I chuckled politely at Isaac’s joke, waiting until he stood back up to look him in the eye.  But when my eyes met his, I looked away.  So blue!  Still, I managed to stammer, "Listen, Isaac...are you going to the Jenderson’s party tonight?  I’m gunna be there.”

"Yeah, I’ll probly go, for a little while.  Hey, Sarah?” he asked.

I looked up at him, eyes wide.  What was he going to ask me?  We were already talking...why did he say my name?  I met his eyes and forced myself not to look away, giving the barest, breathiest, "Yeah?”

He was just looking at me.  My heart was racing, my palms sweaty.  Could he really mean to ask me to the party?  I wasn’t even wearing my dress, and my bulky pants were not especially flattering.  There was a sharp tug at the leash, but I wasn’t about to go anywhere.  I pulled hard on the leash until my knuckles were white, waiting for his answer.

Isaac stammered.  He, of all people, was nervous!  "L-look, I was just wondering, you know, if...”

"Yes?” I asked, barely able to control my excitement.  I heard a whimper.  That wasn’t me, was it?

Our eyes were locked together.  Oh my god, this is it!  The boy of my dreams opened his mouth and said, "Maybe you and me wanted to take off from the party?  I know a -”

Yelp!

Together, the two of us looked down at the sudden, high-pitched bark.

"Holy shit!” Isaac cried, while I joined in (unladylike) with "Fuck!”

Tinkerbell was straining at the full extension of the leash, but Isaac had one of those retractable leashes.  Samson had taken advantage of his relative freedom, and when the two of us looked down, we saw a huge, black-spotted blur mounted on a squirming, brown-and-black Tinkerbell.

How dare she!  First the damned dog is given to Ben without a second thought by my parents, then she ruined my Saturday morning, and now she was interrupting Isaac Laughner right when he’d been about to ask me on a date!  My face was beet red at the awkwardness of what the two dogs were doing, in combination with my anger at Tinkerbell.  She was whimpering and whining as the huge dog pounded her, but I couldn’t help but think the little slut deserved it.

Isaac yanked on his leash, trying to pull Samson off.  "Your dog’s not spayed!?” he cried.

"How should I know?” I asked, "Ben just got her from a shelter yesterday!”  I glanced down at them.  Somehow, I hadn’t noticed it earlier, but Samson sported two, humongous balls, swinging back and forth.  Did that mean Tinkerbell was going to get knocked up?  I just know my parents would blame me, if she did.

"Pull on your leash, we’ve gotta get ‘em off each other!”

I walked to the front of the dogs, yanking on my leash.  Isaac was strong, and he was pulling Samson backwards, but the Great Dane dug his paws in around Tinkerbell’s hips, dragging the whimpering bitch with him.  I wasn’t as strong as Isaac, but I was no weakling, either.  I pulled as hard as I could, but Samson dragged me along as easily as he did Tinkerbell.  The huge dog must weigh fifty, sixty pounds more than me!

"I-I can’t!” I cried, trying to dig my feet into the dirt.  All I was managing to do was choke Tinkerbell!

"Alright...let go,” Isaac said, grimly, letting go of his leash too.  "I don’t think we can stop them.”

Oddly, Tinkerbell looked over her shoulder at the beautiful, muscular quarterback and whined louder, eyes wide.  I got the impression she’d really rather not be where she was.  The spotted behemoth rested his bulk on the German Shepherd’s back legs, making them wobble, while he humped her like she was the only thing in the world.

Isaac and I were panting from the effort.  He walked up beside me, saying, "My parents are going to kill me.  I’m supposed to keep him under control.  Y-you won’t tell them, will you?”

"No, ‘course not,” I muttered quickly.

Tinkerbell dropped her jaw, moaning, while Samson grunted and thrust, his big tail wagging.  Her tail was held motionless to the side, and she didn’t look like she was struggling anymore.  Honestly, she just looked like she was in shock.  Can’t blame her.  If that dog’s as bigger between the legs as he is in total size, she’s gotta be reeling!  He’s twice her weight, easily!  I blushed, realizing that Isaac was probably only a couple dozen pounds shy of twice my size, and then, unbidden, I was picturing his dick.

"Hey, let’s move over a little.”  Isaac grabbed my arm, and pulled me until we were watching the two dogs from behind and to the side.

What?  Now we had a perfect view of Samson’s slick...red?...cock sticking in and out of Tinkerbell’s stretched out hole.  Not mention the Great Dane’s swinging orbs.  Why did Isaac move us here?  Is he some kind of pervert?  I looked up at him, confused.

Isaac gave an embarrassed half-smile, and pointed behind us.  Looking over my shoulder, I saw it.  The playground.  He’d positioned us between the fucking dogs and the playground, where already little kids were looking this way and asking their parents awkward questions.  I blushed at the parents’ harsh, angry stares.  Looking around, I realized how much the two, large, thrusting dogs stood out.  And there we were, just watching as our two dogs bred in the middle of a busy park.  All those eyes!

I whispered to Isaac, "Oh god, is there anything more embarrassing than this?  All those people watching us, judging us.”

Tinkerbell tossed her head up, looking straight at me, giving me a sharp, shrill bark.  What’s her problem?  The German Shepherd hardly had any right to complain.  She’s the one who let the Great Dane bone her in the middle of the park!

Isaac said, "Y-yeah.”

Quietly, I put my hand around his.  He didn’t pull away.  Sweat beaded on my brow as I stood closer to Isaac than I ever had before.  Strangely, despite the incredibly embarrassing act going on right in front of us, I felt comfortable - right - with Isaac.  We were meant to be together.

Incredibly, the Great Dane only seemed to grow larger as he continued to bang her.  I could hardly help but sneak a few glances underneath Tinkerbell’s tail.  She was humping back, now, eyes clenched shut as Samson’s cock seemed to balloon.  Like, literally.  Tinkerbell’s doggy vagina swelled up, wide and round, until it was bulging out far too many inches.  The large male couldn’t possibly be that wide everywhere.

"Wow,” said Isaac, and when I glanced up at him, I saw that he was also sneaking glances.

I blushed red hot, thinking again about the lewdness of what we were watching, and how it made me picture the two of us together.  Giggling softly, I rambled, "It’s not the size that counts.”  Of course, I was immediately mortified, but Isaac didn’t even look at me weird.

Size, however, really did seem to count for something.  Now that Samson was huge and throbbing in Tinkerbell, the German Shepherd was whining and moaning, her hips jerking up and down rapidly.  Any reluctance on her part was gone.  Samson, who had never hesitated, grunted and pumped eagerly into the bitch, short jabs that echoed with a wet schlorp!  I could hardly believe that the small shepherd’s snatch could swell so large - it looked painful.

Then, it all came to a head.  Neither Isaac nor I could pretend not to hear it as Samson groaned, slammed forward one last time, and let loose with a spluuuuurt!  Tinkerbell went crazy, her plaintive whines sounded like some weird combination of intense horror coupled with moaning, blissful humps.  Samson’s heavy balls stood out like sore thumbs, churning and pulsing as he dumped load after load into the slutty bitch.  I’d expected there to be a really sticky mess, but I had to guess that that huge bulge must be keeping it all in her.  Samson continued to gush inside Tinkerbell, which didn’t bode well for her chances at avoiding puppies.

"Look, Sarah.  If she has puppies, you know me and my family will do everything we can to help you, you know, with whatever you do.”

I glanced up at Isaac, squeezing his hand, and said, "I know.  I guess, you might as well ask your friends and family if they’re interested in some mix puppies.”

Still gyrating her hips, Tinkerbell suddenly dropped her jaw and wailed, her eyes on me.  I swear to God, it looked like she was shooting an accusatory glare! At me!  I shook my head at Tinkerbell and said, on no uncertain terms, "This is your fault, not mine.”

Isaac laughed, and Tinkerbell whimpered.

Just when I thought the embarrassment would be over, and the angry parents and curious onlookers would go away, Samson didn’t simply get off of his bitch.  Instead, he turned around.  Now that looked painful.  The huge dog stood back-to-back with the smaller shepherd, cock as huge as ever inside her.

I winced, and Isaac chuckled and said, "It’s a dog thing.”

Well, turns out Samson wasn’t even close to finished with her.  Another eight minutes passed while Isaac and I stood, holding hands, before the Great Dane had finished ejaculating into my brother’s heat-crazed dog.  With a loud grunt, he tugged, tugged, and tugged, finally pulling free of the whimpering Tinkerbell.  Now there was a mess, as Samson’s excess stuff went spilling out of her still stretched out pussy.  Hopefully, when Isaac and I finally consummated our relationship, it wouldn’t be so painful and gross.  Whoa, girl! I thought.  We aren’t even dating yet.

"Look, Isaac, I gotta go home and get ready for the party,” I said, grabbing Tinkerbell’s leash.  The Jenderson’s party wasn’t starting for eight hours.  Stupid!  Stupid!

Isaac blinked and said, "Yeah.  Um...Sarah?  Like I was saying, before, um, Samson...”

"Yes,” I interrupted, firmly.  Isaac looked at me with hopeful, puppy dog eyes.  "Yes, let’s ditch the party early.”

Isaac lit up like a bonfire, his cheeks flushed.  He said, "Great, uh...uh... I’ll see you there!”  With that, he grabbed Samson’s leash, turned around, and almost tripped over his own feet as he headed for home.

* * * * *

The walk home from the park was humiliating.  Actually, the walk to the park was pretty bad, too!  Though I suppose the park itself took the cake, if you’re baking shame.  I was a fourteen-year-old boy, not a four-legged dog.  Appearances could be deceiving.

Sarah almost surely didn’t know that I was really Derek, the neighbor boy.  Only Ben knew who I was, and I doubted he would ever tell anyone.  Would they even believe him?  It’s not every day that a suburbanite kid turns into a German Shepherd.

Sarah and that older boy, Isaac, just watched and did nothing as the monstrous Great Dane sniffled around under my tail, chasing me.  Sarah even kept the leash taut, making me easy prey for the horny mastiff.  What could I do?  Samson weighed twice as much as me.  Unable to run, all I could do was stand there and whimper as the huge canine mounted me.

To add insult to injury, all the two teenagers did was watch me get raped and flirt with each other.  Sarah even blamed me, twice.  I wanted to bite her, but that didn’t seem like a very safe way to stay out of the pound.

All those eyes watching me.  Not just Isaac and Sarah, but at least three kids from the playground, three angry parents, one shocked and far-too-intrigued ten-year-old from behind a tree, two smiling old people, and one guy in a parked car who looked like a pedophile.  All watching me get fucked by a Great Dane.

And liking it.

Just like before, I couldn’t stop myself.  He was huge!  I felt like I was being ripped apart, and still I ended up humping and whimpering around his throbbing cock.  The best part was getting pumped full of his cum, spurt after spurt splattering my clenching pussy.  I moaned in utter ecstasy, forgetting my large audience.  God, I really am a Slutpuppy!

Something about being in heat made every breeze, every touch, every thrust feel indescribable.  The pleasure coursing through my body more than overcame my embarrassment, so that as much as I hated it, I whined and humped shamelessly beneath the massive Samson.  What was wrong with me!?  The only consolation, I figured, was that I was probably already pregnant by Pancakes and Beefstick.

Take that, Karma, I thought.  Karma must have run into Ben Hendricks, because like me, it was really a bitch.

Sarah almost ran home, skipping and jumping the whole way.  She’d gotten a date with the school quarterback.  I found it a little hard to be happy for her, considering what I’d just gotten from the school quarterback’s Great Dane.  And Samson didn’t bother to buy me dinner and a movie.

I had to jog the whole way beside her, slop spilling out of my sore vulva onto the sidewalk as I went.  She certainly wasn’t going to clean me up.  The house seemed empty when we got home.  Mr. and Mrs. Hendricks were gone, and if I knew Ben, he was still asleep.  Sarah ran upstairs, taking the steps two at a time, and there I was, alone.

Escape?  Even if I could have operated the doors (which I couldn’t), where would I go?  I could try to contact Zack and give him some sort of message.  If I had any idea where Ben had gotten the potion, I might try there.  No, I was pretty much trapped.

At least I could clean myself off, now.  I glanced around the house, looking for paper or cloth towels...something other than the carpet.  I didn’t want to mess the house up if I could help it!  It’s not like all the Hendricks deserved it.  But if I were in Ben’s room, I wouldn’t hesitate to jump into his bed and wipe my cum-stained pussy all over his sheets.

Unfortunately, I couldn’t find a single towel within reach.  My fur was starting to dry out, matting awkwardly beneath my tail.  I had to do something.  Sighing, I curled up into a ball, sniffing my rump cautiously.

It didn’t smell too bad.  Besides, my stomach was growling.  I took a tentative lick.

Wow, I thought, it tastes great!

I would never have guessed it, but Samson’s spunk actually tasted really good.  Salty, but filling.  I began to lap it all up as quickly as possible, like when Pancakes had gotten a bowl of peanut butter to hide his pain pills (he’d jumped the fence and gotten into a fight with a larger dog).  None of the Hendricks had remembered to feed me yet, and I was none-too-anxious to be humiliated, eating dog food, so the large gulps of dog seed would have to do.  I’d read somewhere that semen was high in protein.

Then, I began licking my mound.  Three rough uses by three rough dogs had definitely stretched me out, Samson’s huge knot in particular.  My tongue dove inside me, gulping up every drop of cum I could find.  I whimpered as I curled up, desperate to drink every drop, and another feeling was beginning to overtake my mind.  Each powerful thrust of my tongue spread me apart, rubbing forcefully against my clit.  Soon, I wasn’t looking for food anymore - I was just humping noisily around my wide, wet tongue.

My hips flew, and almost as quickly, my pussy rocked away from my tongue, leaving me empty and gasping.  I tried again, but the same thing happened.  Every time I got close to getting myself off, I would jerk my hips around and slip free.  My genitals ached and burned with desire, but no matter what I did, I couldn’t satisfy myself!

Desperate, I went to the back door, wondering if I could somehow make it into my own backyard, lying in wait for Pancakes or Beefstick.  What am I thinking? I gasped, tucking my tail between my legs.  I just had to get myself under control - I wasn’t about to go seeking a stud...was I?

Shaking my head, I turned away from the door and had the sudden urge to get as far away from the backyard as possible.  The stairs!  I clambered up the stairs, panting.  There was Ben’s room, door closed.  The next one was Mr. and Mrs. Hendrick’s, and down the hall, past the bathroom, lay Sarah’s room, a thin sliver of light peeking out the side of the door.  It was open a crack, so I padded over to investigate.

There were strange noises coming from inside.  Curious, I pushed the door open just enough to walk inside; the door moved silently.

There, on her bed, lay Sarah, and she was naked.

I froze, then backed up instinctively.  My butt smacked the door, and it slid closed with a loud click!

"Ben!” Sarah screeched, looking up at the closed door.  Seeing me, the naked seventeen-year-old relaxed, and said, "Oh, it’s just you, Tinkerbell.”

While I stood there and watched, Sarah went back to what she was doing.  My jaw dropped as her hand slid down between her legs, and she pushed two fingers into her wet pussy.  She’d closed her eyes, and gave out a muffled moan that my sharp ears could easily pick up as "Isaac...”

Oh...my...god.

The girl I’d been having wet dreams about for four years was masturbating in front of me, completely unaware that I was anything more than just a stupid dog.  Not only that, I couldn’t have left if I’d tried - the door had latched behind me, and I had no hands.  Most likely I’d have fled with my tail between my legs if I could have, but now I was presented with an inescapable opportunity.  I’d never even kissed a girl, much less seen one naked, much less seen one masturbate.  Slowly, entranced, I stepped closer, eyes locked between Sarah’s legs.

My heart was racing.  I would never have imagined what girl’s pussy would really look like.  This was nothing like the little pointy mounds on the bitches I’d grown up investigating for my sexual education.  Sarah’s lips were pink and puffy, yes, but they didn’t stand out very far from her body.  Now I knew why I’d heard them referred to as ‘flowers’ before.  Sarah pulled her petals apart, moaning, inadvertently showing off the wet tunnel inside of her.  I could have died.  My jaw was on the floor.  She slid three fingers into her clenching pussy, squeezing down around them.  Her fingers were slick and fragrant.  I cocked my head, taking it all in, more aroused than ever.

"Tinkerbell, what are you doing?”

I glanced up at her, meeting Sarah’s eyes.  I realized that, without thinking about it, I’d moved until I was only a few inches away from her pussy.  My fur had rubbed against her legs, startling her.  Damn it!

Not only that, I was drooling.  My slobber was falling down onto the sheets below her.  Horrified, I took a step back, but no more.  Maybe...maybe she’d let me watch if I behaved.

Sarah didn’t continue, but she didn’t stop either.  Instead, she just lay there panting and sweating, looking at me curiously.  What did she expect?  I couldn’t actually answer her question.  She thought I was just a normal dog.  Was she getting suspicious?

"You’re probably hungry, aren’t you?” she asked, glancing about the room.

No, don’t feed me.  Pretend I’m not here! I begged.

Sarah’s eyes locked on a half-full jar of peanut butter, next to a plate with toast crumbs and a butterknife.  "Here you go, girl,” she said.  How humiliating.  She grabbed the jar and the knife, and got a large dollop of peanut butter on the knife, extending it toward me.

Well, I was hungry, I couldn’t deny that, and peanuts were pretty sure to be a lot better than dried meat cubes.  I licked my lips, eyes fixed on the knife.  Was it so easy to distract a dog?

Instead of offering me the knife however, I watched the seventeen-year-old slide the knife between her legs, spreading the creamy food all over her wet pussy.  "Eat up,” she said, shivering and leaning back against her big, fluffy pillow.

I blinked, gaping.  She...  I...  There was...  How...?

Forget it!  What was I doing!?  I edged up until half my body was on the bed, and licked.

"Oh, God, what am I doing?” Sarah moaned to herself, and I was wondering the same thing.  But I wasn’t about to look a gift horse in the...pussy?

Sweet, tasty peanut butter filled my mouth, and I gulped it down.  It tasted great and all, but I was far more interested in what lay beneath the butter.  I bobbed my head up and down, slurping noisily as I lapped at her mound.  Sarah jerked her hips, but only spread her legs further.  It didn’t take a lot of furious licks to get all the peanut butter off, leaving only her wet, naked pussy in front of me.

"Oh, Isaac!” she cried.

I rolled my eyes, but I wasn’t going to let a bit of humiliation stop me.  Taking a deep breath, I leaned between her legs and buried my tongue between her swollen lips.  Instantly, her strong hands grabbed my head, but she didn’t push me away.  Instead, she pulled me closer.  I slid my wide, wet tongue into her hot, tight cunt, glancing up her naked body to watch the young woman moaning, her hefty breasts heaving.

The taste was amazing.  Salty and savory, my first taste only made me want more.  Sarah’s fingernails dug painfully into the back of my head, but I didn’t care.  I rammed my tongue this way and that inside of her, gulping down every drop of sweet wetness I could find.  But every time I schlurped away her juices, more seemed to appear.

Sarah rocked her hips and yelped.  Startled, she clapped a wet hand to her own mouth, to muffle her moans.  She didn’t want to wake Ben, I supposed!  She whimpered and clenched down hard around my tongue, but that just made my slurps that much more forceful.  My heart raced.  I was getting her off.  Sarah.  I could hardly believe my luck!

"Mmmmph!  Nnnnrg!  Errrrrrrph!” Sarah moaned through her hand.

I pushed forward, until my wet nose was pressing up against her clit.  I knew firsthand what that felt like, thanks to Pancakes.  My tongue pumped in and out of her, and Sarah couldn’t hold back any longer.  She opened her mouth and said, "Tinkerbell!”

Inwardly, I grinned.  At least she had the right person, if not the right name.  I wondered if I was the first boy - scratch that - first one to get her off.

That’s when she exploded.  A wet gush of fluid spilled on my deeply embedded tongue, and it was all I could do to gulp it all up without choking.  Worse, her clenching cunt squeezed even harder.  She did at least manage to keep her shuddering whimpers quiet.

I drank her down eagerly, bobbing my head in time with her frantic upward thrusts.  She kept one hand over her mouth, the other grasping her own breast.  I watched her face contorting in ecstasy, knowing that it was me doing that to her.  I couldn’t exactly say I was glad to be here like this, but how long would it have been for me to see a girl like this if I hadn’t been transformed into a dog?  Not with my reputation at school.

"Oh... Ohhhhh...” she panted, then put her hands on my head and pushed away.  "Owww...”

I pulled back, licking my wet and dripping lips.  Her pussy was quivering, but it was pretty clear she didn’t want me licking her anymore.  I knew the feeling: her lips must be burning from the orgasm.  But I also knew from Beefstick’s insistence that the pain sensation faded pretty quickly.  And I was hornier than ever.  I had to do something, since I knew I couldn’t get myself off.

I pulled my hind legs up onto the bed and walked over the shivering, moaning woman.  I don’t think she even noticed me until I straddled her, my hind paws on either side of her waist, and my front paws brushing gently up against her sweaty breasts.  She opened her eyes to see me staring down at her, and she gasped, "Tinkerbell...?”

Sarah, naked beneath me and moaning my ‘name’, I did what only came naturally to me.  I lay down on her and licked her face.  My chest buried her breasts in fur, my tail wagged back and forth between her legs, and, most importantly for me, my pussy pressed right up against her wet opening.

Sarah whimpered and tried at first to push me off.  "Stop...” she whispered.

I licked her cheek fast and hard, her juices still lingering on my tongue.  It wasn’t a cock, but my raised, pointed mound would have to do.  Heart pounding, I started rocking my hips, grinding my soft, swollen lips against hers.

"Oh...!” Sarah gasped, surprised.  As soon as she opened her mouth, I filled her with my tongue.  She whimpered, her tongue powerless against mine, moving her hands straight to my neck and pushing me away.  But I wouldn’t be swayed.  I pushed harder, lapping everywhere inside of her mouth.

She was stronger than me, though, and pulled me away from her mouth, no matter how hard I pushed against her.  Eyes wide, she said, "Jesus Christ, Tinkerbell, what am I doing!?”

With that, she opened her mouth and let go of my neck.  In seconds I was back inside of her, wrapping my flexible tongue around hers and humping madly against her pussy.  Sarah kissed back, tilted her head to let me push even deeper, while she wrapped her arms around my back.  Oh God, this is really happening!

Schlurp! Schlurp! Schlurp!  I pressed my muzzle up against her mouth, tasting her saliva and letting her taste mine.  One hand slowly slid down my back, resting finally above my tail.  Even as we kissed, Sarah began to push down on my hindquarters, squeezing my mound all the harder down against Sarah’s trembling pussy.

While I whimpered, she moaned, and then I felt her other hand sliding between our bellies, her sweaty arms rubbing up against my teats.  But that wasn’t her goal.  Before I knew it, she’d reached her tender lips and spread them apart.  To my amazement, the next time I humped against her, my protruding mound pushed inside her.

It wasn’t much, but it was something.  I pounded my hips against her, spreading her apart with my inch-long mound.  This was about as close as I would ever get to fucking a girl, now, and only a day after transforming.  Sure, I’d really lost my virginity well before this, to Pancakes, Beefstick and Samson.  But this was close - damn close.  I kissed her and moaned and penetrated Sarah, barely giving her time to gasp out for air, saying, "Tinkerbell!”

My mound was pressing up against her clit, making her tremble and moan.  My pussy burned, but I knew from experience that my clit was buried deeper inside me.  I whined and groaned, trying to get off on the sheer thrill of fucking a girl, but it wasn’t enough for me.  For Sarah, though, she was in heaven.  She exploded again, coating my pussy with her juices as she trembled and rocked her hips against mine.  She pulled her face away, breaking our kiss to moan, "Tinkerbell!” again, panting desperately for air.

I had to do something with my dripping tongue, and so I splashed it up between her sweaty breasts, lapping between the heaving orbs.  "Oh...God!  Don’t stop!” she whimpered.

I moved my muzzle over and began suckling one of her nipples.  Sarah arched her back and moaned, fingers gripping the bedsheets as I drove her wild.  "God...oh, god!” she repeated, "Unnnnf, don’t...God...”

"Stop!” she exclaimed, and this time she sounded like she meant it.  She pushed weakly at my furry body, and as much as I wanted to stay on her, humping away, I relented.  Whimpering, I pulled away from her naked body, leaving the seventeen-year-old shivering, sticky on the bedsheets.

I watched her though, naked and gasping for breath, her face bright red and sweaty.  "God, god,” she repeated.  "What did I just do?”

She was so beautiful.  Thinking back, I could hardly believe I’d had the nerve to do what I did, but in the heat of the moment, I couldn’t suppress my lust.  In a lot of ways, that paralleled my lust for the three dogs who’d fucked me, but this time my mind was happily along for the ride.  I’d never imagined a girl would be so sexy, but now, having done all this with Sarah, I knew that I’d never have trouble masturbating again.

Oh, right.  I was a dog now...and forever.  I would never masturbate again - at least not that way.  My pussy ached and burned with desire, but I knew I couldn’t satisfy myself.  Still...I had to try!

Curling up on the bed beside the panting Sarah, I lifted a leg and slammed my tongue into my soft, tingling cunt.  Almost immediately, I humped up and down, squeezing hard around my tongue, but no matter how hard I tried, my tongue still pulled free, leaving me empty and cold.  It was like torture!  How could I ever get off if every time I got close, I lost control?  I whimpered pitifully, trying again.

"Tinkerbell...what’s wrong?” Sarah asked, watching me lapping at my pussy.  I would have been mortified, but then, my own tongue had recently been burrowed in her cunt.  Considering she’d just fucked a dog, I figured I wasn’t the one who should be embarrassed.

She blushed a deep red when she realized what I was doing, but she kept watching.  It didn’t take long for her to realize why I was whimpering, rocking my hips vainly against the air.  "Oh...oh,” she said.

I didn’t need her pity.  I slurped again, hoping that the fifth time would be the charm.  But no, no luck.

"Let me...um...help you,” Sarah murmured.

Eyes wide, I looked over at her.  She couldn’t mean...

She did.  Hesitating, she crawled across the bed to me, reaching a hand between my legs.  I dropped my jaw, reflexively rolling over onto my back.  This couldn’t be happening!

It was.  All four of my legs dangled in the air, Sarah positioning herself kneeling over my rigid tail.  I stared at her in disbelief, but softly, carefully, she reached a shaking hand to my trembling mound, and touched it.

Electricity shot through my body, unlike anything I’d ever felt.  My spade began instinctively jumping up and down, bouncing at her touch while I shivered, arching my head back and whimpering.

"You like that, don’t you?” Sarah asked, inquisitively.

The best answer I could give her was to spread my legs further apart, yipping softly.  She took this as a yes, she reached forward again.  "What am I - well, it’s only fair,” she said.  I watched, quivering, as she brushed the tip of her finger against my y-shaped folds, bringing her middle finger out as well to gently spread my vulva apart.

"Well, if you can take Samson, you can take this,” she decided out loud.  I took a deep breath, and sure enough, Sarah pushed her finger into my heat-swollen pussy.  I yelped, hammering my hips up and down against her, but unlike my tongue, Sarah’s finger stayed put, buried deep in my wet, clenching cunny.  I squealed in a very unmanly way, but I didn’t care.  I would suffer any indignity to satisfy my lust, and if this worked out, it would surely be less embarrassing than lifting my tail for Pancakes again.

Placing her free hand on my abdomen, Sarah rubbed and petted the soft fur and tiny teats, starting to push her finger in and out of me.  I groaned, gritting my teeth and squeezing desperately around that long, firm finger, squirming and panting in bliss.  "Good girl!” Sarah said gently.

Penis or vagina, if it felt this good, I didn’t care.  I whimpered so much it formed one, continuous whine, and I was just about to get off when she pulled her finger free.  Frantic, I yelped, "No, don’t stop!”  Of course, only barks came out.

Sarah seemed to get the picture, so she reassured me.  "Don’t worry, girl.”

I watched curiously as Sarah slid off the bed so that her knees were on the ground, leaning over to grab me by the hips and slide me across the covers to the edge.  I whimpered, until I felt her hands grip and pat my belly on either side.  My little nipples trembled at her touch.  But it wasn’t enough.

Sarah lowered her mouth between my legs, and I yipped in shock.  She couldn’t...

She could.  I couldn’t fathom it, but my next-door neighbor lowered her lips to the wet, trembling pussy of her brother’s dog, and licked it.  Was I dreaming?  Could all of this really have stemmed from simply walking in on her masturbating?  I spread my legs and clenched my eyes closed, incredulous.  Her warm, wet tongue spread my lips wide, pushing inside of me.  Her finger was good, but this was unbelievable.  Sarah was eating me out!

Whining, I squirmed, but her strong grip on my stomach kept me firmly in place.  I humped in a frenzy around her tongue, even as she pressed her lips fully around my mound, suckling the sensitive flesh at the same time she jabbed her tongue as deep as she could.  The very tip of her tongue brushed up against my deep, hidden clit, and that was it.

I howled and gushed all over her tongue.  I writhed, groaning and whimpering as the pleasure I’d been seeking finally reached my brain.  I was in a different world.  Sarah made sure I didn’t go anywhere, holding me in place and keeping her tongue inside my puppy cunt.  She seemed determined to ride out my entire orgasm, though I doubt she realized just how long she was in for.  My canine body was designed for up to twenty minutes; Sarah only managed to keep licking and lapping at my juices for five before she pulled out and gasped for breath.

Finally empty, I lay back, panting, a warmth spreading evenly through my body and half-closing my eyes.  I could have stayed like that forever, but Sarah stood up.  "God...that was...that was...”  She paced back and forth, and added with amusement, "I thought only dolphins and humans had sex for pleasure.  But a bitch in heat - first Samson, now this.  You’re quite a little slut, you know that?”

I just met her eyes and smiled, my tongue dangling out of my mouth.  Would she...want to do this again?  Maybe there were some perks to my new form.

Besides, if I was a slut, what did that make Sarah?

Chapter Text

I woke up and glanced at my clock.  Shit, it was already 3:00!  I’d slept my whole fucking Saturday away, when I could have been humiliating Derek!  Or should I say "Slutpuppy”!

Groggily, I slid out of bed, stumbling over to my clothes.  I didn’t need to take a shower - I wasn’t planning to go anywhere anyway.  At least not with kids.  Sure, they all respected me and laughed at my jokes, but we didn’t, you know, hang out.  A better arrangement than when I hung out with that dweeb Derek.  Ha!  Come to think of it, I really didn’t have any friends anymore.  My last one was a bitch now!

I could still hardly believe that magic had worked, but I wasn’t about to question it.  Derek Smith was so stupid and useless that this was an upgrade for him.  Now instead of annoying me, he was amusing me.  And more...I tried to pull on my jeans and noticed I had a bit of morning wood - or afternoon wood, anyway.  Sure I’d always been a little turned on by all the random dogs fucking in the Smith’s yard, but when I knew that it was Derek panting and humping beneath Pancakes, it was another thing altogether.  I’m fucking amazed Mr. Smith didn’t notice the huge tent I was pitching.

Thinking about it only made my hard-on worse.  I needed to jack off, badly.  I turned toward my computer and hit the button to power it on, when I heard ka-click!  My sister’s door closing!  She wasn’t usually around this late.  Curious, I opened my door a peek, making sure to keep my boner hidden.

It wasn’t Sarah, but Derek.  I didn’t think he - I mean, ‘she’ - could use a door with those paws.  Probably Sarah just kicked her out of the room.  That fucking dog was probably trying to spy on my sister, that faggot.  I watched the German Shepherd for a minute.  She was panting and licking her lips.  Probably caught a glimpse of my sis’s cooter.

Beep!   My computer was done starting up.  Wait a fucking minute.  Why the hell would I masturbate?  I’ve got a queer bitch dog now.  I opened the door, and called, "Slutpuppy, come!”

She just glared at me.  The nerve of that motherfucker.  I bet he would, too, if his mother ever gave him the chance.  But she wouldn’t because even she knew how pathetic Derek was.  Oh, and because she’d never ever see her son as a boy again.  I glared back and said, "You want to go to the pound, fucker?  Get in here!”

That did the trick.  ’Slutpuppy’ lowered her tail and cowered, then walked forward.  I opened the door for her, and snapped it shut when she got inside, locking it.  I wasn’t about to risk my sister walking in on what was about to happen.  The former boy still glared at me as I chuckled and sat on the edge of the bed, saying, "How was your first night of your new life, dogfucker?”

She sat on her haunches, not moving, just watching me.

"What’s the matter?  Cat got your tongue?  Just wag your tail if you’re happy.”  She didn’t move her tail an inch.  I clenched my fists.  "Ungrateful little bitch!  I know how much faggots like you love cock, think about all the dog-dick you’re going to be getting now!  It would have been four hundred fucking years before some dude took pity on you and fucked your ass.”

I was getting nowhere.  The old Derek would have been bristling by now at comments like these, all but ready to punch me if he didn’t realize how bad I’d beat his ass down.  Slutpuppy, though, just took it quietly, not even fazed.  This was no fun!

Well, I knew what to do.  "Well, now that you’re a working dog, time to get you acquainted with your new job - doing anything I want.”  With that, I unbuttoned my jeans and slid off both my pants and underpants, grunting as my hard cock entered the chilly air.  My dad liked to keep heating costs down, and this was proving to be a pretty cold autumn.

That got Derek’s attention.  Her jaw dropped, and she was staring at my exposed dick.  I knew she was a fag.  This was going to be easier than I thought.  "That’s right, girl.  You’re gonna suck me off, and you’ll fucking like it.  And if you don’t - or if you try to hurt me - believe me I won’t feel sad for one second while the vets are injecting you full of poison.”

Eyes wide, she began shaking her head back and forth, inching backward looking abso-fucking-lutely horrified.  Good, Derek still wants to live.  The day she finally gives up hope is the day I lose control of her.  And the day she’ll have to die - one way or another..

I slid my pants the rest of the way off, until I was completely naked.  "Come on, bitch, I haven’t got all day!”

I guess I was surprised she really went for it.  I know I’d rather die than lick another dude’s cock.  But then, I wasn’t a fag like Derek.  Though she cringed, she started walking toward me.  "Good girl!” I praised, laughing.

She growled at that, which only made me smile wider.  This was so awesome!  I’m so glad my bitchy sister made us go to that dipshit’s magic shop.  Think of all the money that...Ruth?...could be making with potions like this?  "Go ahead, keep growling,” I sneered.  "I always wanted a dog-skin rug...”

That shut her up.  She stopped just in front of me, refusing to look at my exposed dick.  "Pretty big, huh?  Bigger’n your pencil dick, anyway.  Oh wait, I forgot - you don’t even have one anymore.”

Derek didn’t seem amused, but I was laughing my ass off.  "Now get lickin’!  I wasn’t joking, you little homo.”

Now, I put on a good show, that’s for sure, but my heart was racing on the inside.  No one’d ever touched my cock but me before, much less seen it.  I wasn’t gay, so I didn’t go around showing it off to my old friends.  I wouldn’t even be doing this if I didn’t know from rather close inspection that Derek was a bitch now.  Besides, she wouldn’t be telling on me.  I was her master now, and I was going to take full advantage of that fact.

Derek hesitated a lot before she finally picked her front paws up and placed them on the edge of the bed between my spread legs.  My stiffy was just inches now from her face.  For a first blow job this was pretty weird: she’d been a boy the day before and now he was a dog, but she was a girl now, and she wasn’t really a dog for real.  So, it wasn’t really sick or anything.

"Come on, Slutpuppy,” I said, impatient.

I was panting already, my blood pressure through the roof as I watched the German Shepherd in disbelief.  She leaned forward, closing her eyes and taking a long, tentative lick along the base of my cock.  Oh god!  It felt awesome, but I couldn’t help from tremble watching those sharp teeth so close to my pride and joy.  Even before the first lick was done, leaving a thin trail of warm saliva, I grabbed her head in my hands.  Immediately I felt better, like I was in control.  "Faster, bitch,” I encouraged.

She did lick faster, slathering the belly of my rigid cock.  I pushed Derek’s muzzle this way and that to reach just the right places.  I thought it would be like masturbating, but it wasn’t fucking anything like it.  When I jerked off, I anticipated every motion, every sensation.  Now, even with my hands guiding the action, I felt helpless.  My whole body shuddered just from first few long, wet licks, watching Derek drop her jaw like a whore and wrap her huge, warm tongue around the base of my penis.

"Rrrmmm...” I groaned, slowly rocking my hips up and down against her tongue.  "Gooooood giiiiiirl...” I managed to add.  I pushed her muzzle up so she was lapping at my tip, which instantly began to feel numb, almost painful!  Already I was leaking a few drops of cum, so I shifted my hips around, smearing it across Derek’s nose.  I’m not sure the fucking slut even noticed, still licking with her eyes closed.

One drop followed another, until my pre was spilling down my tip onto my shaft, but to my amazement, Derek just gulped it all down, finding every last drop and slurping it up.  "Holy shiiiiit!” I groaned.  It had only been a few seconds, but watching Derek go to town on me like that had me ready to explode already!  She was licking faster and harder now, really getting into it like the cockfag I knew she was.

I tried to push the desperate bitch away to cool off and let the moment last, but she pushed forward, her tongue glued to my dick.  "Ah!  Ah!” I cried, shifting my weight to get a better grip on the bed.  With my new position, I could finally push Derek away, but it was too late.  "Ahhhh!” I cried, holding the German Shepherd’s a few inches away as I shot all over her face.  Two, thick spurts splattered her face, the strongest ejaculation I’d ever felt.  The first smacked right into Derek’s right eye, and the second landed flat in her open mouth.  Even as I shuddered, I watched the horny bitch gulp it down.

God damn!  That was -

"Ow, hey!” I cried, pushing ‘Slutpuppy’ away.  As soon as I’d let her head go, she was back on my cock, slurping up the last few dribbles from my climax.  It hurt!  "Stop that!” I reprimanded, but she was still pushing forward to get a lick.  She even whimpered pitifully, licking her lips, her eyes fixed on every drop of cum.

I held her there, panting, for a few moments, until I was ready.  I let go of her carefully, saying, "Alright, clean it up.”  I swear, Derek’s tail was wagging as she leaned forward and lapped up and down every inch of my cock.  It still hurt a little, but at least it was clean.  I wouldn’t need a tissue this time.

"Jesus Christ, Derek,” I said, accidentally forgetting to use her new name.  "You really are a faggot.”

* * * * *

What was I doing!?  Sure, I didn’t really have much choice but to suck Ben off, but I didn’t have to enjoy it.  But, just like with Samson, once I got a taste, my body lost control.  My cheeks burned as I lapped at Ben’s salty, musky cock, humiliated each time he called me ‘girl’ or dirty names.  Even though I hated what I was doing and the last thing I wanted to do was please Ben, I couldn’t stop myself.  I had to have every last drop of cum.

Not that there was much of that to go around.  I’d gulped up ten times as much from just the seed that spilled out of my pussy after Samson had taken me.  Ben just gave two little spurts, and that was it, and he must have only lasted thirty seconds.  I licked my chops, refusing to look at my former friend and his smug, pleased grin.

Ben got up and threw on some clothes, not bothering to shower even though I could smell the sweaty odor of his body from miles away.  He did at least put on some deodorant, but it hardly covered up his aroma.  Luckily, along with my super sensitive dog nose, like a dog, I didn’t care too much about ‘bad’ odors—smells were just smells.

"Come on, Slutpuppy,” Ben said.  "We’re going for a walk.”

I followed him, if only because I knew he’d force me to follow him eventually.  How on earth was I going to get out of this?  I couldn’t talk, I couldn’t write (very well), and if I started acting too weird, Ben could use that as an excuse to send me to a shelter.  Even if I did write something in the dirt, in all likelihood, they’d refuse to believe it was me, and not some sort of prank (especially with Ben around).  I could jump the fence (maybe) and run for it, but I didn’t even know the magic shop’s name.  I’d likely end up in a dog-catcher’s net.

Sarah was my best bet.  I had to show her my intelligence, slowly, over time.  Nothing too creepy to spook her, but building, so that she couldn’t deny each individual step until she finally realized that I was not a mere dog.  Then I could write for her.  Until then, I’d have to be obedient...

Downstairs, Ben found the leash, and latched it onto my collar.  Then, he saw the dog food and laughed.  "You’ve gotta be hungry, huh, Tinkerbell?  Let me get you some delicious kibble.”

He used scissors to cut a hole in the bag, a rich, meaty scent wafting from the opening.  He poured about a cup of meat cubes into the bowl and set it in front of me, saying, "Eat up!” condescendingly.

Jokes on him!  It smelled delicious, and judging by my recent...change in opinion over tastes and smells, I knew it would taste delicious.  Sure, it would be humiliating to eat out of a bowl like a dog in front of Ben, but nowhere near as humiliating as getting fucked by three dogs in front of him.  Still, I decided to pretend like I wouldn’t like the food, so that he wouldn’t lose interest in feeding me.  I know Ben had a lizard when he was eight and it died of starvation.

I took my first, crunchy bite, and cringed.  But it was just acting - like I suspected, the meat tasted great, even if it was the brand-name brands that I knew were mostly soy and corn.  And I was ravenous.  I found it really difficult to slow down and keep up the appearance that I was disgusted.  I tucked my tail between my legs, making absolutely certain I didn’t wag and give the game up.  Still, I couldn’t help but lick up every edge of the bowl when done, to Ben’s raised eyebrow.

"Come on, girl, time to show you off!” Ben grinned.

He probably didn’t know I had already been for a walk.  He seemed to think that I would be crushingly humiliated being walked like a dog, but it just reminded me of Sarah, which just reminded me of...what happened in her bedroom.  Ben kept yelling "heel” and "sit” without much regard or sense, but I performed admirably.  And, whenever we passed another person, Ben stopped and chatted them up.

"Such a beautiful girl!” one of our neighbors said, kneeling down to scratch behind my ears and pet me.  It felt pretty good, and, come to think of it, I was pretty beautiful.  The potion hadn’t skimped on my new form - I was possibly the best example of a German Shepherd I’d ever seen, and dozens upon dozens had come to be bred in our backyard.  Coupled with my intelligence, I could win every dog show this side of Paris.  Wait, every dog show.

Somehow, I doubted Ben knew what a good specimen I was, or I’d already be registered.  He would just love to enter me into shows.

After the fifth person he showed me off to, I think he gathered that I didn’t mind the attention.  His goal was to humiliate me!  His best effort was to say, "This change has really boosted your popularity!”

I shrugged that off like so much water off a duck’s back.  Of course I was more popular as a dog.  Who wouldn’t be?  Short of celebrities, I couldn’t think of one person who wouldn’t be more appealing if they were a canine.  But I’d never strived for popularity, I’ll take my hands, feet, and voice back, thank you very much.

Ben sighed, clearly not getting the reaction he wanted.  Maybe I should have acted more ashamed (and I should have), but I was enjoying frustrating the teenager too much.  He walked around the corner of the block until he reached the train tracks that run a short way behind our houses.  He took off into the train yard, which was all but abandoned, these days.  Trucks and boats carried most of the freight these days, and passenger trains were completely dead.  A train only came through about once every week, thankfully.  They were loud as hell running past our neighborhood.

Big fences lined either side of the three track system, to keep little kids from wandering out of their backyards onto the tracks, but there were gates with high latches to move in and out.  No trains were running, and on the third track, old, broken train cars sat and rusted.  I used to come out here to read or think, when Zack was bugging me too much.

I walked near Ben’s left side, like a good dog, as we walked past our own backyards.  I could hear Pancakes and Beefstick barking and playing behind our high fence.  What were my parents doing?  I’d been gone almost a full day now.  They must have already called the police.  Didn’t Ben care about what he was doing to them, if not me?  Zack wouldn’t mind, at least.  He’d always said there wasn’t enough room for two boys in the house, and now I wouldn’t ‘hog’ the Xbox.

We passed my house, and then Ben’s, still walking along the tracks, until the tracks split into four.  I’d seen this place a few times before, and it was the old loading yard.  Nobody came here anymore, and thanks to the large fences, we were as far from civilization as we could get while still being in the city limits.  I glanced up at Ben, curious as to why we were stopping.

"Alright, Slutpuppy,” he emphasized, even though we were clearly alone.  Was he going to make me lick him off again?  He lead me over to a post next to the old, unused track, and quickly tied me there.  As he walked over to a nearby, rusted train car, he continued, "Let’s see how well that smelly cunt of yours works.”  He sat down, pulled out his PlayStation Vita, and started to play.  It sounded like FIFA 13.

I stood there, all alone, while Ben played his video games.  I looked around the yard, but not a soul moved.  I think I saw a cricket jump.  If he was expecting dogs to be lining up to fuck me, he was going to be sorely mistaken.  Sure, I absolutely reeked of heat, but scent didn’t travel on its own.  Only stray dogs who followed our route here would have a chance of finding me, and unlike most bitches, I hadn’t been peeing every ten steps along the way.  Smiling, I sat down and watched Ben, making sure to meet his eye each time he looked up, disappointed.

My triumphant expression was definitely frustrating my former friend.  A minute passed, and then an hour, when finally Ben shut off his Vita and said, "We’re not leaving here until you’ve been fucked, if I have to do it myself!”

He wouldn’t really do that, would he?  I mean, a blowjob was one thing.  Needless to say, his new threat wiped the smile off my face.  The sun was just beginning to set, and Ben was pacing.  I think he was trying to decide if he’d have to fuck me, just so he wouldn’t lose face.  For better or for worse, I never had to find out.

There, back along the trail we took, was a large, black dog.  He looked like a mix between a Doberman and a black lab, judging by his floppy ears, wide muzzle, and bright, golden-brown chest.  He was just a bit smaller than a full-grown Doberman.  I could tell he was male by the shiny, red point sticking out between his legs.  Ben laughed when he saw him, and gave me the best pinched up gloating face he could.  "Let the show begin!”

Was I frightened?  Was I relieved?  I knew that if Ben didn’t find a dog here, he’d find some other, more horrible way to humiliate me.  As embarrassing as it was to lift my tail to every passing dog, was I really dreading it?  Pancakes, Beefstick, and Samson had all made me shudder, whimper, and moan beneath them.  I had no reason to think this mutt would be any different.

Blackie was certainly forward with me.  He’d no sooner reached where I stood tethered to the post then he’d poked his nose beneath my tail.  His hot breath slathered at my swollen pussy, and my tail shot up.  Instinctively, I felt like spreading my hind legs and taking him, but I knew better.  Ben would think that I wanted it.  Maybe I did?  Regardless, I yipped and swiveled my hips away, pretending to snap at my would-be suitor.

Ben laughed.  "I don’t think he’s going to take ‘no’ for an answer, Slutpuppy.”

He was right.  Blackie chased me and I dashed back, until I hit the end of my lead with a yelp, forced by my collar to turn and face him.  With nowhere else to go, I trembled as the large, black dog took his time, sliding up alongside me until his tail was wagging in my face.  He snaked his nose around beneath my tail again, sniffing.  I could hardly avoid seeing Blackie’s heavy, intact balls, and just below that, his swelling cock.  This was one virile, well-hung stray...

Whose size, if I didn’t do something soon, I would experience firsthand.  I considered attacking him, but he was larger and stronger than me, I was tied to the post, and I’d only been a dog for a day.  I wouldn’t know where to begin in a fight.  I’d just have to make it impossible for him.  I lay down, planting my belly on the ground with my tail between my legs.

Blackie whined, stymied for the moment.  But he wasn’t going to give up.  He climbed over me, mounting me anyway, and began to waggle his hips back and forth.  I could feel his slimy dick brushing through the black fur on my rump.  Ben chuckled, grabbing his iPhone.  "I’ve gotta record this - maybe I’ll put it on YouTube!”

My ears perked up at that.  This ordeal was bad enough without thousands of disgusting thirteen-year-olds watching videos of me being dry-humped by a dog online!  I had to stop Blackie!  Still, though, if I just stayed put, the horny mutt would have to give up eventually, and I’d manage to avoid a second fucking today.  For what?  So Ben could post a ‘funny’ video online, and then realize he needed a breeding harness to keep my hips in the air and get me fucked anyway?  I had to stop Blackie and hope that Ben forgot all about recording me...

The dog’s cock had grown considerably as he pounded my back.  He might have gotten his smaller stature from a black lab, but his dick was pure Doberman.  Judging by the sticky mess in my fur, he probably would have gone all the way, if I hadn’t acted.  I couldn’t just lie there while Ben recorded us!  Growling, I launched myself out from underneath him, spinning to face the Doberman-mix with a snarl.

Blackie looked startled, squaring off defensively against me, his glistening dick dangling beneath him.  His knot was already half-swollen!  Uncertain, the male tentatively moved to my left, but I headed him off, snapping my jaws.  I wasn’t about to let the mutt get around behind me again.

Frustrated, he began to growl, darting to my right.  I would have none of it.  I wasn’t going down without a fight.  Ben said, "You’d better give him what he wants, or I think he’ll tear you up and then take it.”

As if Ben knew anything about canine behavior.  Still, I didn’t have much experience with strays, and those teeth looked awfully sharp.  I growled and held my ground.  Blackie charged to my right, barking and snapping his teeth.  I swear my heart folded in on itself, but I turned to face him and planted my feet.  I could do this!

Except that the Doberman-mix had only been feinting.  I darted right, and he pushed off to swivel to my left.  Before I could turn again, he was behind me.  I leapt and turned, but he turned with me, until my hips collided with the post, knocking the air from my lungs.

Blackie didn’t waste one moment before he was on me, his strong, black paws curled around to hold my hips up in place.  He jostled my spine with his fierce thrusts, his bony tip searching for my puffy entrance.  I squirmed and jumped, but Blackie’s grip was too strong - he’d caught me, and one glance at Ben was enough to show that the camera was still rolling.

"This is great stuff!” he said, excitedly, trying to keep his hands steady.

I took a deep breath and braced myself.  Just like the other dogs, Blackie didn’t care whether I ‘wanted it’ or not.  Now that he was on my back, I knew that what was coming was inescapable.  I closed my eyes, lifted my tail, and tried my damndest not to think about Ben recording us.  The bastard had moved slowly closer, lowering the iPhone and angling behind me to get a nice close up of what happened next.

Hump!  Blackie launched himself forward, his full, throbbing cock burying between my legs.  My wet cunt spread easily for him, slurping over and around his shaft.  Ben laughed, catching it all on tape, even the loud splorch! when the mutt slammed his enormous knot against my tight, puffy folds.  I was already gasping for breath, but the force of the collision knocked the air out of me again.  He wasn’t even close to fitting!

But the big, stray dog seemed determined to try.  He picked up a steady rhythm, quickly withdrawing his dick only to ram it wetly back in, the steady slap, slap, slap of his blocked knot echoing across the old train yard.  I struggled to free myself, but his grip was too strong.  All I could do was drop my jaw and whine while he pounded me mercilessly.  Why hadn’t I just raised my rump to him immediately!?  He was supposed to swell inside of me, not try to ram right through my aching pussy!

Ben walked backward for a wider view, making sure to get the whole picture: the Doberman-mix humping the German Shepherd’s brain’s out, his heavy balls swinging back and forth.  "Good boy,” he said, more to the camera than to Blackie.  "Knock that horny bitch up!”

Unfortunately for Blackie, if I even was fertile, he was probably already too late.  Pancakes and Beefstick had had the first crack, and if they failed, it would be Samson.  I could only pray that the magic, though powerful, hadn’t made me a receptive bitch as well.  What would I do if I got pregnant?  How could this all have even happened, that I’d be asking such a question?  What if...what if Ben taped me giving birth?

In and out he thrust, and as much as the collision at the end hurt, I couldn’t help but feel my insides slowly burning up, a building heat that threatened to overwhelm my mind.  The powerful male’s cock spread my eager vagina apart, rubbing almost painfully up against my trembling clit.  I was Blackie’s whether I wanted it or not, and as the seconds ticked by, I wanted it more and more, until my whines turned to moans and I waggled my hips up and down, whimpering.

He gave two quick shoves that sent me reeling, my triangular mound stretching noisily apart.  I felt like I was being torn apart for several seconds as each, heavy pump wedged more of his swollen glands into my cunt.  Whining desperately, I grinded myself against his rock hard cock, spreading my legs until my knees shook from the strain.  I just hope Ben couldn’t see my tail wagging just out of his view.

Blackie’s hot breath washed over the back of my neck, a large dollop of drool splattering my fur.  He gritted his teeth, and with a grunt, launched himself forward one last time, to a deafening SQUELCH!  His whole, huge cock burst inside my quivering pussy, the massive knot making my mound bulge lewdly out.  As much as I wanted to ignore my former friend, I noticed Ben moving his phone up for a close-up of the tie.

Blackie clung so tightly to my slender hips that it hurt, his claws digging shallowly into my abs.  With a heady howl, he punctuated his short, hard thrusts with a piercing splurt!  The fourth dog in less than twenty-four hours began to pump his bubbling cum into my tight little womb.  I tossed my head back and howled too, my entire body leaping and squirming in sudden, blissful spasms.  Again I had to wonder why I fought so hard to keep these dogs off of me, when their throbbing cocks made me cum so fucking hard.  I was still rocking my hips and yipping like a puppy when Blackie turned around, his still pulsing balls squeezed up between our butts.  I whined, my womb full and sloshing with his seed, wagging unapologetically in time with the mutt.  Finally, our heavy panting was catching up with our desperate need for air.

Ben said, "Thus ends day one in the heat of Tinkerbell, affectionately known as ‘Slutpuppy’.  Look at that bulge...”  He held the phone up for another close up, before scanning the device over to me.  I glared at him, feeling the heat rush to my face once again.

Ben chuckled, "Ooo-ey does she look pissed.  I guess she wants some ‘alone time’ with her stud.  Stay tuned for tomorrow, when we’ll meet the next lucky dog to jump Tinkerbell.  Or will this one get a second turn?”  With that, the teenager turned off the camera, and said, "You’re going to be an internet superstar, how about that, Derek?”

I growled at him, but he was too far away for me to bite.  He wouldn’t really post these, would he?  It wouldn’t be against YouTube’s policies, so the videos would be online for anyone to see, forever, even if I managed to change back to a boy.  I wanted to think that Ben would never be that cruel, but here I was, tied and whimpering to the first mutt to sniff me out.  Ben clearly had no decency left.

* * * * *

And so began my routine for the next week.  Every morning I would undo my pants, slip off my underwear, and call Derek over.  Say what you want about the little queer, but she was a champion cocksucker.  I rarely lasted two minutes before I came all over her face.  I didn’t have to order her to lick it all up - she did that herself.

School started up again on Monday, which was fucking torture, but I couldn’t skip or my parents would get on my ass, and the last thing I wanted was to be grounded.  The show must go on!  The minute I got home, I put her on the leash and walked to our special spot in the train yard.  The first couple of days, I had to wait a while, but pretty soon Derek’s slutty scent was all over that place.  Dogs would come from miles around to see ‘Slutpuppy’, and I made sure to record every lewd, messy fuck.  Twice, a train came by right in the middle of a fuck session, and I can only what the engineers were thinking.

By the end of the week, I would get at least two recordings in before dinner, and another two after.  The big black mutt seemed to make the train yard his home, always ready for another go.  But there were plenty of others.  Let’s see, there was that big, mud-covered mutt that looked like a cross between a poodle and something with pointy ears.  There was the husky with the collar...what was the name?  Bonkers Pravacek.  I wonder if the Pravaceks knew what (or who) their dog got into when they let him out.  Then there was the Pitbull.  God, that fucking thing was smaller than Derek, but he just grabbed her by the scruff and forced her down in one smooth, practiced motion and proceeded to plow her like she was nothing.  I wonder how many other bitches he’d treated the same.  And the twins on Thursday.  Two nearly identical black-and-white spotted dogs teamed up against Derek.  One would hardly be done with her before the other grabbed her cunt again.  At one point, one had been so impatient he leapt onto the wrong end and dry-humped Derek’s face.  There were more, I know I’m forgetting some.

I still hadn’t posted the videos online, though.  I needed to figure out a good way to do it anonymously.  Maybe I could upload them at the library?  Regardless, I wasn’t in a rush.  All that mattered was that Derek thought I was posting every video online.  I’d even tell her some of the ‘comments’ she was getting.  "Animos312 says he never knew a dog could be such a fucking slut.  Will she ever stop?” and "You just reached one million views!”

I was so caught up in videotaping that I completely missed when the police showed up at Derek’s house.  I had to walk Derek past the police car to get to my house, while the policeman talked to Mr. and Mrs. Smith on the lawn.  Derek saw them, of course, but she didn’t so much as whimper at her parents.  Was she forgetting her old life?  Or had the little faggot grown to like her new life so much she didn’t want to change back?  Or maybe she didn’t want her parents to look her over and notice the sloppy cum-stains gushing down her cunt.

The police questioned me too, but I wasn’t worried.  What could they do?  There wasn’t any evidence that lead to me, and they weren’t about to accuse me of witchcraft.  I just said I didn’t know, said he’d had home troubles, and probably ran off.  I gave them my best puppy-dog eyes which worked with my idiot parents every fucking time, and said, "I just hope, wherever she...he is, he’s happy.”

Unfortunately, I think she really was happy!  She made no effort to alert the police, even as she stood beside me.  Sarah seemed to like Tinkerbell, and took the dog for walks in the morning, and sometimes would take Derek to her room to read.  I was already almost certain the gay-boy was getting off to her new life, and then today sealed the deal.  It was Friday, two days after the police showed up, and we were in the train yard right after school.

The Pitbull showed up first, and took the first turn, quickly subduing his submissive German Shepherd bitch.  Too quickly.  And then there was the little orange dog.  I had to look it up: a Pembroke Welsh Corgi.  He also had a collar and his nuts were fucking huge for such a short, stubby little dog.  He could barely reach Derek’s cunt when standing up on two legs!  He was insistent, though, hopping up and down like a crack baby and slathering his tongue all over her pussy.  But try as he might, the little Corgi didn’t have a chance with Derek.

Until Derek rolled over.  Right there in front of me, Derek whimpered, rolled onto her back, and spread her legs.  I swear, I almost shit a brick.  Here, Derek finally had a fuck-buddy she could actually say ‘no’ to, and she was saying ‘yes’.  I had to make it sting.  I laughed, "Oh my fucking God, you really want it, you queer!”

What used to ruffle her fur had no effect.  She just tossed her head back, moaning and humping her hips as the surprisingly well-endowed Corgi climbed onto her, missionary style.  I kept the iPhone camera rolling, but she knew I’d been taping her all this time.  She must have come to terms with it.  All my best lines and I couldn’t even make Derek blush!  It was infuriating.

After the Corgi pumped Derek’s sore little cunt full of dog cum and went contentedly on his way, the black mutt showed up, and I shit you not, Derek just stood up, spread her legs, and lifted her tail, looking straight at me the whole time.  Impudent little bitch!

But that wasn’t even the worst thing that happened today.  Before he could shove his meat thermometer into Derek’s cock socket, another dog showed up.  He came from down the tracks, toward the old pine forest.  At first, I thought he was another husky, but he was a lot bigger, and greyer, and moved like he ruled the world.

"Holy fuck, a wolf!” I yelped, scrambling backwards so fast I tripped over myself and hit the dirty, metal floor of the train car, hard.  I clambered to my hands and knees, forgetting about my iPhone and jumping out the back side of the train.  I ran for the nearest fence, and scraped my knee climbing over it.  I landed with a thud on the other side, my heart thudding in my chest.

Was I safe?  I didn’t know, but I was sore everywhere, and out of breath.  Over the fence, I heard growling, and then a loud yip and a canine running.  What was happening!?  Was the wolf chasing me?  I stood up, and peeked over the fence, to make sure I was safe, and to check on Derek.  God, what if the wolf was hungry?  What would he do to a free hot dog tied to a post?  I was so fucking far from being done with Derek.

I had to step to my right to see through the train car.  The wolf was hungry, for sure, but not for food.  I watched as the humongous wolf grabbed Derek’s scruff in his teeth and slammed himself home into her cum-sopping cunt with a wet squelch.  Derek yelped, trembling, completely at the wolf’s mercy.

I watched, entranced, as the bloodthirsty beast pounded Derek into submission, using her like a fuck toy.  She could barely hold her ground, digging her claws into the gravel and letting out an ear-splitting whine as his humps jostled her back and forth.  He fucked her ragged while Derek yelped, her mouth and eyes wide open.  Then she wailed in some combination of fear and lust as the wolf tied her, short, sharp thrusts jerking her around as if she weighed nothing.  Almost at the same time, both canines tossed their heads back and howled, shuddering as they both came buckets.

I had to wait ten minutes before the wolf managed to tug himself free, and I swear, Derek was cumming the whole time, squealing each time the wolf’s balls clenched and squeezed another heavy load into her swollen baby chamber.  He just panted patiently, back-to-back with her, not even looking at the bitch he was seeding.  When he was done with her, he simply took off for the forest, not once looking back.

When he was far enough I way, I climbed over the fence again, wincing at my skinned knee.  I climbed into the train car and grabbed my iPhone, which had been recording the floor of the car the whole time.  Derek was watching me, her tail wagging and her tongue lolling.  What kind of expression was that?  I said, "What?”

She glanced downward, and I followed her eyes, and then I saw.  My pants were wet.  I’d...pissed myself, and she was laughing at me.  At me!  I had a dozen recordings of her getting off to dog-fucking, and she had the gall to laugh at me!

I grabbed her leash and dragged her home, but the whole time I knew she was laughing at me.  I’d show her.  If getting fucked by dogs wasn’t humiliating her anymore, I’d just have to take it a step further.  I looked out the window at her old house, and saw Zack throwing a tennis ball for Pancakes and Beefstick.

I knew exactly what to do.

Chapter Text

I woke up and realized I’d been crying again. Damn it, I told myself I’d stop doing that! My brother would be back any day now, and then I’d look silly.

Derek had been gone for an entire week now, and still the police had nothing. Officially he was listed as a runaway, and I hope that’s the case. If he ran away, he could always run back. I still remembered the last thing he said to me before heading out the back door and disappearing...

“But I covered for you yesterday...”, he’d said. I couldn’t even remember what stupid game I was playing at the time, but I ignored him. He let the dogs out, and disappeared from my life.

My parents tell me it wasn’t my fault; that Derek loved me, and he left for some other reason. I don’t know. I was always making him do my chores, and I hardly spent any time with him. Maybe he knew I never defended him when the other seventh graders called him a dog-fucker? Maybe he’d somehow overheard me joining in?

I only said it because I didn’t want the other kids accusing me, too.

The police questioned all his high school friends, but none of them had any inkling that Derek might run away. Dad thought that Derek might have run away when Ben’s new dog, Tinkerbell, got into the yard and bred with Beefstick. Dad was mad, of course, because he was a responsible breeder, but not mad enough to justify my brother’s running away and never coming back. We kept expecting Derek to show up that night, or in the morning, but he didn’t, day after day.

At least at school I was distracted. It was the first Saturday since Derek left, and if I wasn’t careful, I’d start crying again. I needed to get out - to do something. Somehow I didn’t think Call of Duty was going to cut it today.

I got up and threw on my Taekwondo pants; I’d shower after working out a little. I really felt I needed to punch and kick things, and the punching bag outside called to me. I tossed on a white t-shirt and headed down the stairs, noting the clock. Noon. I’d slept badly yet again.

The crisp, autumn air really helped to wake me up and dry my eyes. We always cleaned up after our dogs, so I didn’t bother getting shoes, just walking across the grass to the punching back. I started with my favorite kick: a spinning jump crescent kick, right at the top of the back. Smack! It felt good to finally be out and doing something, even if I’d rather be searching for Derek. My parents made me promise not to go looking though, and to leave it to the police.

They didn’t want to lose me, too.

Thwack!

Front kick! Backfist! Sidekick! The bag went flying as my foot shot through it, bouncing back as the chain reached its end. Even in the light breeze, I was working up a sweat, breathing carefully just as I’d been taught. I wouldn’t get my second degree black belt if I couldn’t manage my air.

“Hey, Zack...”

I jumped, spinning around. There, at the fence, was Ben. I knew what he’d done to Derek over the last few years, so I narrowed my eyes. But even as much of a jerk as he’d been, wouldn’t he be sympathetic now that Derek was missing?

“Yeah?” I said, clipping the end.

“I just want to say, I’m sorry about what happened to your brother.”

I took a tentative step forward, treading carefully. “Yeah.”

Ben looked down, then up at me. His eyes were shining - was he crying? The fourteen-year-old choked up, saying, “I can’t help but feel somehow responsible. Maybe if I hadn’t teased him, he wouldn’t have run away...”

“It wasn’t that, or he would have run away a long time ago,” I shrugged, not sure whether or not I believed the older boy. Besides, if he ran away, it was because of me.

“I just hope,” Ben said, “that wherever he is, he’s happy.”

“Yeah,” I said. Whatever. I just wished he’d leave me alone!

“Are you okay?” he asked suddenly.

“Huh?”

Ben peered over the fence at me, looking me up and down like Sensei Johnson. “You don’t look okay. You...wanna hang out? I got nothing going on today anyway. We could watch a movie or something.”

I wrinkled up my face. Spending time with Ben? From what I’d heard... How could I even consider hanging out with this boy after what he’d done to Derek? But what excuse could I give? I didn’t have anything going on, either.

Ben said, “Have you seen American Pie?”

My eyes went wide. Of course, I hadn’t seen it. It was an old movie now, but my parents still knew about it from when Derek was younger and asked to see it with Ben. Boy did he get in trouble when they looked up the movie!

“My parents wouldn’t let me.”

“Do you only do what your parents say?” he asked. “They don’t have to know.”

I didn’t know what to say. I was curious, for sure, but I was only twelve and it was rated ‘R’. And not your normal kind of ‘R’, but ‘R’ for sexual content. There was like a ‘fatwa’ on sex at my house: internet filters, monitored movies and games, and we were even pulled out of the school’s sex education classes. My parents would kill me if they found out! But would they find out? With Derek still missing, would they even care?

Ben interrupted my obvious hesitance, saying, “Come on, I promise it’ll take your mind off of Derek better than kicking that bag will.”

I grimaced at Ben, but I knew he was right. And as much as I’d seen dogs breeding, I was a fair bit more interested in my own species. “Alright, fine, but if you tell my parents, they won’t believe you.”

“You don’t have to worry about that, I promise,” he said, smiling.

I nodded carefully, and went through the gate to Ben’s yard, following the older boy into his house. We walked right into the kitchen, which was far, far messier than my parents let our house get. There were magazines piled up on the dinner table, dirty pots and pans in the sink, and haphazardly placed appliances covering the counters and even the top of the refrigerator. My parents would have yelled at Derek and me to clean it up ages ago, but as I looked closer at all the magazines and junk, I wondered if maybe Mr. and Mrs. Hendricks were the problem. I doubted that Ben or Sarah reads “Home and Garden” or needed an electric mushroom slicer.

“Want a drink? Gatorade maybe?” Ben offered.

“Yeah, sure, why not?”

“Let’s see,” he said, looking through the refrigerator and grabbing a little bottle of some clear Gatorade. “We only have watermelon.”

“That’s fine,” I said, shrugging as I grabbed the small bottle.

Ben started up the stairs.

“Where are you going?” I asked, pointing to the television in the living room. “Aren’t we going to watch that movie?” I tried to play it cool, but I really did want to see it. Maybe I’d finally understand all the references the other kids made.

“Oh, the T.V. in my room is way bigger,” he said simply.

I opened the bottle of Gatorade as I followed him up the stairs. His room was the first one on the right, and he walked right inside. I followed, lifting the drink to my lips.

Ben’s room was even messier. Dirty clothes were strewn on the floor and his bed, and all over his closet. He did have a huge T.V., 42 inches at least, and I wondered why Ben got a better T.V. than the rest of the family. And a mini-fridge! And his own computer! And his own dog - there was Tinkerbell, lying on the floor, the smallish German Shepherd relaxing lazily in the clothes.

Until she saw me standing there with that bottle in my hand. It all happened so fast, I can’t recall it clearly. I took a gulp of Gatorade, and the dog shrieked, like someone cut her tail off, jumping straight at me, paws forward. Ben yelled, “Hey!” and I coughed on the drink, pulling the bottle away and putting my free hand in front of me. The sixty-pound bitch collided straight into my chest, but I set my feet and she barely put a dent in me.

Tinkerbell barked and jumped again, but Ben was there, grabbing her collar and yanking her back. “I don’t know what’s gotten into her!” he gasped.

My heart was racing. What if she’d tried to bite me? I wiped the sweat from my forehead, while the dog kept barking madly at me, choking herself in her attempts to reach me. I’d never seen a dog act like that before! I took a big gulp of Gatorade to cool myself off, and then another one. “Maybe she smells my dogs on me...”

“Calm down, girl!” Ben urged, clapping a hand around her muzzle so that her frantic barks became nothing more than muffled whimpers. Still, she struggled in Ben’s grasp, but weighing less than a third his weight, she was helpless.

“It’s okay, girl,” I said soothingly, finishing off my drink and tossing the bottle in the trash. “It’s okay, I’m not going to hurt you.” I crouched down in front of her to appear smaller, making sure not to look her straight in the eye. She was really freaked out, staring straight at me. Very strange for a dog.

“Shush, shhhhh,” Ben whispered into her trembling ears. It finally seemed to be working, however. She was calming down, though her wide eyes showed her fear.

I offered my hand slowly to her, as Ben let go of her muzzle, and she didn’t make any effort to attack me. “It’s okay. I’ll just sit over here so she doesn’t freak out again. Movie?”

Ben waited for me to sit in the swiveling chair, then let go of Tinkerbell and approached the T.V. I glanced over at the dog, and she was staring straight at me, ears flat, as if she expected me to do something at any moment. I stayed put, while Ben slid the DVD into his player.

“This movie is sooo hilarious,” Ben promised.

He grabbed the remote, skipping past the stuff at the front of the movie and playing it right away. I sat at the front of my seat, watching nervously as the opening scene began to play. I couldn’t believe I was actually sneaking off to watch an ‘R’-rated movie! The pure sneakiness was thrilling me.

The movie was, in fact, hilarious, but I could understand why my parents didn’t want me to see it. It was all about sex, and I could hardly believe how much they were showing! I’d never seen anything like it, and I’d barely gone fifteen minutes before popping a boner. I shifted my legs to hide it, transfixed on the screen.

Tinkerbell stared at me for even longer, but after a while she seemed to calm down, and then, weirdly, seemed to be watching the movie, too! I’d never seen a dog watch T.V. before, but I guess when something as interesting as American Pie was on...

I’d finished the Gatorade ages ago, and was getting pretty thirsty again, when Ben opened his little fridge and said, “Hey, check this out, Zack.”

I looked over there, and watched as Ben removed a shiny white piece of cardboard from the back of the fridge, revealing a secret stash of bottles...of beer. I dropped my jaw, even as he pulled one out, popped the top with a bottle opener, and offered it to me.

I froze, trying to remember all the things my parents had said to do whenever someone offered me drugs, but my heart was racing and I couldn’t come up with anything. I just sat there, flabbergasted, until Ben said, “Oh, come on, it’s only a beer. It’s not going to kill you. Don’t make me drink mine alone.”

I couldn’t, could I? I was already breaking all the rules by watching this movie. I was only twelve for God’s sake! Still, I was really thirsty, and what young adult wasn’t interested in trying alcohol? I took it from him, glancing over at Tinkerbell who was watching me and bristling. Weird dog, I thought, taking a drink.

Blegh! It was disgusting! I choked it down, watching Ben take a gulp without even flinching. Well, it did slake my thirst at least, so I took another drink, trying to grimace a little less so that I didn’t look like such a baby to Ben. Why did people like this stuff?

As if the first half of the movie wasn’t awesome enough, the second half was incredible. Everything was drop-dead funny, and Ben and I were reduced to giggling fits. Better, all of the kids ended up actually having sex. God, how I wished I were them. Maybe Derek was off...fucking girls or something. I took another gulp, but my beer was out. Looking down, I noticed two other empty bottles in my lap. Had I really had three?

“Oh...my...God,” I slurred, “That was the most funniest movie ever.”

“Hell yeah,” Ben said, stretching his arms. “But it always makes me so hard.”

“Yeah, I - what?” I asked, looking over at Ben.

“Always reminds me of my first. You ever fucked a girl, Zack?”

I’d never even seen a girl naked. I shook my head, speechless.

“It’s pretty great,” he said simply. “Too bad my most recent girl just moved north. Porn is great and everything, but it’s nothing like the ‘real thing’.”

Ben had had a girlfriend? I didn’t remember any, but then, my brother and he’d stopped hanging out over a year ago. Ben was just starting high school, and he’d already lost his virginity? There were girls I liked at school, but I hadn’t even built up the nerve to ask one to dance, much less ‘go steady’.

“Porn?” I asked, feeling so young and inexperienced. Didn’t his internet have a filter on it like us?

“Yeah, of course. What do you want, stories? Magazines? Videos?”

“Videos??” I gasped. He couldn’t be serious!

But Ben just smiled and walked over to his computer, double-clicking a folder right there on his desktop. Inside were 30 gigabytes of videos, each with a title more interesting than the next. “How come your parents don’t find these?” I asked, trembling, walking over beside the older boy.

He snorted. “Yeah, right. They never fuckin’ check up on me. Ooh, here’s a good one: ‘Black Dicks in White Chicks’.” he asked, clicking the video.

I froze. I was absolutely not ready for this. Watching porn with another person? Not to mention an asshole like Ben. But he’d already clicked the video, and it was loading as I watched. I couldn’t look away.

They were completely naked. American Pie had nothing on this. I swear my brain almost exploded from information overload, looking at the girls’ pussies, the guy’s dicks, breasts... There wasn’t any plot in this one, and just a few seconds into the video, one girl was sucking a dude off while the other two were having actual sex, right there in front of me. I stood there, rigid...in more ways than one.

“Pretty good, huh?” Ben asked, as the three-minute video ended.

I didn’t even look at him before saying, “Another one.”

He double-clicked on a ten-minute video called ‘Barely Legal 13: Eighteenth Birthday Orgies’. Four guys and four high-school girls, each doing things I’d only ever …three minutes ago. I watched, transfixed, until this video ended too, and glanced over at Ben.

His pants were open, and his dick was out! I dropped my jaw, cutting off whatever I had been about to say. Holy shit, he was masturbating right in front of me! I’d touched myself a little a few times, until my dick started to hurt, but that was it. I also noticed Tinkerbell sitting on my other side, her eyes on the computer monitor. Did dogs watch porn, too? Human porn?

“Go ahead and drop your pants, I don’t care,” Ben said, clicking the next video, ‘Human Bitches: Ruff Sex.’

There weren’t any men in this one. Just a twenty-year old in an empty room with a black Labrador. It took me several seconds to register what happened next. She had the dog on his side and was rubbing his sheath. I was dumbfounded. It couldn’t be real, could it? But there weren’t any special effects or anything. Just a girl and a dog sporting a huge boner. I gasped when the woman slid her mouth around the dog’s wet cock.

“Come on,” Ben said, humping against his hands. “Drop your pants.”

My dick was pressing hard against my Taekwondo pants, so I untied them and let them fall around my ankles. Without looking away from the woman and the dog, I cupped my hard-on through my underwear. I had no idea this sort of thing even existed. As much as what the woman was doing shocked the hell out of me, I had to keep watching.

Together, the three of us watched the video until I saw the girl pull her lips off of the dog’s cock and crawl on her hands and knees in front of him, spreading her legs. “She’s not really going to...” I said, incredulous.

“Just watch,” Ben replied.

The black lab walked over to her and sniffed her clean-shaven pussy, then started to climb on top of her. “Holy shit...she can’t!” I said. Wasn’t this illegal!? Who would actually let a dog fuck them!?

The camera descended behind the two, looking up and between her legs, leaving no doubt about what happened next. I held my cock tight, trembling with anticipation, just knowing that something was going to interrupt them. Maybe one of those black men from the first video would barge in. They couldn’t really show a woman having sex with a—

Hump!

The big, swollen, red cock pushed right into the girl’s pussy, spreading her wide while she gasped. They were doing it - really doing it. My dick started to really hurt again, and I had to let go, panting. They showed several different shots, but all of them showed the truth: she was fucking a dog. “Oh...my...God...” I gasped.

It didn’t last as long as I wanted. He humped her for a minute or two before knotting her like a bitch in heat. She was not just willing to fuck him, she seemed to be really loving it, shuddering and moaning and clawing at the ground. My dick ached, and I wasn’t even touching it!

The video ended, leaving the room in silence other than Ben and my heavy breathing. He was still running his fingers over his dick and groaning, but he managed to gasp, “I’ve got hundreds of videos just like that.”

Hundreds!? Not only did they find one willing woman, they’d found many. “Who would...do that?” I asked.

“It’s not that big of a deal,” Ben said, shrugging. “It’s just a dog. You’re telling me you’ve never tried to get your dogs to lick you?”

“W-What?? No!” I stammered.

“Tinkerbell sucks me off, every. Single. Morning. She loves it.”

My eyes widened, and I looked at Tinkerbell to my left. Almost as if she sensed my gaze, she hung her head. “You’re kidding.”

“No, I’m not. Here, I’ll show you. Tinkerbell!” he called, swiveling his chair to present his wet dick in the air.

But if Tinkerbell loved it, she sure didn’t show it. She took one look at Ben’s cock and looked away, ears flattened. “Bad girl!” he admonished. “Come.”

Still she sat there, rump glued to the floor. “Aww, I guess she’s too shy to perform in front of her br... In front of us bros. Here, I’ve got an idea,” he added, tossing me his cell phone.

“What?”

“You’re going to want to record this,” he said, grinning.

I turned on the camera, holding up the phone, even as I stuttered, “W-What are you going to do?”

Ben gave me a knowing glance, though I had no idea what I was supposed to know. He said simply, “Just watch.” With that, he got up, his half-drawn pants and underpants sliding down around his ankles. He kicked them both off, now wearing just a shirt and socks. I recorded, frozen in place as Ben walked over to the cowering canine. She looked up, surprised to see him, and she yipped when he grabbed her by the shoulders. The broad-shouldered fourteen-year-old easily picked up the sixty-pound German Shepherd, kneeling as he pulled her closer. Then, he turned her around until she was facing away from the camera, keeping one hand on the scruff of her neck, and the other firmly around her tail.

Whimpering, the young dog struggled in Ben’s grasp, and I noticed then that she was definitely in heat. Below her raised tail lay the puffiest, swollenest spade I’d ever seen. She shouldn’t have been, since she was already deep in season heat a week ago when I’d watched Beefstick breed her hard. I guess her period must have just started.

“She’s got other holes that can’t resist me. Are you getting this?” Ben asked, lifting himself so that, still on his knees, his rather large dick was hovering just inches from that wet, bouncing mound.

Whining, obviously in distress, Tinkerbell pushed and pulled against the hands holding her neck and tail, but she could do nothing to stop the boy. Does he really mean to...? The bitch clearly didn’t want it, but I was too transfixed to think about her. “You...you can’t!” I yelped, still managing to keep the camera dead center.

“Don’t worry, Zack. She’ll love this.”

My jaw dropped as he made good on his innuendo. Right in front of me, and on tape, my brother’s former friend pushed his fat cock up and into his female dog. At an angle behind the two, there was no mistaking it. I could see his pink flesh sliding up inside her outstretched lips, both like and unlike the many times I’d seen our dogs breed a horny female. Whether Tinkerbell was horny or not, she dropped her jaw and howled, but her voice fell on an otherwise empty house.

Now violating his dog right in front of me, Ben let go of the German Shepherd’s tail, reaching forward to grab her around her front legs, one hand firmly around her collar. Ben leaned over her, humping his hips as he wedged himself deeper and deeper into her. The porn videos were one thing, but watching this lewd display only a few feet from where I recorded it... I couldn’t look away.

Ben lifted his butt to hammer her harder, giving me a straight-on view of his asshole, and also his balls, hovering just above where his dick speared the whimpering dog. He grunted and said, “Take it, Slutpuppy! It’s about time I gave you what we both know you really want.”

She was just a dog, obviously, but his words really seemed to affect her. She laid back her ears, jumping and struggling. But nothing she did could dislodge the large teenager fucking her. Ben just groaned and slammed forward, wet smacks filling the air. Her whining was so loud that it finally got through to my (admittedly, pretty buzzed) brain and I realized he was raping her.

“Ben, stop,” I said, though I placed the camera upright on the desk to keep recording. “She doesn’t like it!”

“Oh yes she does,” he countered, moaning and gritting his teeth. With great effort, Ben managed to slow his thrusts, and say, “See?”

Sure enough, even when Ben was doing nothing, Tinkerbell was now humping and even wagging her tail! When Ben let go of her collar, she just yelped and kept shuddering around him, allowing Ben to get a nice firm grip around her hips to start really going to town on her rump. Looking at the dog’s face, I saw her ears flat against her head, but she was moaning. Her one visible eye was glancing back at me, and if I didn’t know better, I would swear she was blushing at me.

I nodded, my throat dry, unable to say or do anything except put my hands to my cock. My underwear was in the way, so I quickly lifted my butt up and slid them off, gripping my dick with both hands as I watched.

Ben’s cock spread her apart again and again, until the boy was sounding a constant moan. I knew he couldn’t last much longer. But, it turns out, Tinkerbell came first, howling again with a different tone. Her tongue spilled out of her mouth as she began to shudder, her claws digging into the floor. She bounced up and down in Ben’s grip, chest heaving, and from what I could see, her vulva was spread wide and clenching down around the base of Ben’s fully buried cock. “Oh God!” Ben yelled. “Here it comes, gay-boy!”

At the time, I didn’t even think about that weird name, I was just entranced watching Ben tremble and cum into his bitch. I sat in awe at the fourteen-year-old. I’d never even really masturbated fully, but here he was, going all the way with a dog. I could only guess at how many actual girls he must have fucked!

The groaning boy’s balls trembled, but after only a few seconds he’d spent himself inside of Tinkerbell. Gasping, he fell backward, leaning back against his deck and leaving the dog trembling on the floor with her rump raised to the camera, showing off her white-splattered pussy. Her mound still bounced, as if she were still cumming.

“Holy fuck!” I said, simply, humping softly into my hands. Looking down, I saw that my tip was dripping with pre-cum. Gross. But I could worry about that later. My cock was burstingly ready, and I needed to cum bad. Just one more look at Tinkerbell’s gaping spade was enough, and with a grunt, I shot my wad all over my stomach. The built-up pain disappeared, replaced with the most mind-blowing pleasure I’d ever experienced. I moaned and squirted with all of my might until I was sore. It came suddenly - one second, I was humping and groaning, and the next I had to pull my hands off my dick, yelping in pain.

Ben had fully recovered by the time I could think again, after experiencing my first orgasm. He laughed. I gasped for breath, then took another look at Tinkerbell. The bitch was curled up on the floor, ramming her tongue into her own pussy as she lapped up every last drop of Ben’s cum that she could reach. My cock jumped, but damn did it hurt. I tried hard to watch without getting turned on.

Tinkerbell was looking up at me while she licked, her posture very meek. Her ears were laid back, her tail tucked between her legs, and her gaze looked strangely desperate - like nothing I’d ever seen on a dog before. Most dogs avoided eye contact, but she was looking straight at me, like she knew me.

But no, I was imagining things. She is just a dog.

* * * * *

“You’d better clean up your br...Zack, too,” Ben suggested.

I winced. Was Ben slipping up on purpose to rub it in my face? Zack was too buzzed to really pick up on the clues that ‘Tinkerbell’ wasn’t what she seemed, and besides, even if Ben outright told my brother that I was Derek, the twelve-year-old still wouldn’t believe him. I wouldn’t either, in his position. What had happened to me was absolutely crazy!

When I looked over at the sticky mess all over Zack’s belly, my disgust was tinged with lust. Whether it was part of the magic or not, I just had to slurp up every last drop of cum I could find. I could ignore Ben, for now, concentrating instead on my heat-swollen pussy, but my face was burning as I slid my tongue deep inside those folds while my own brother watched.

As embarrassing as it was to eat myself out in front of Ben and Zack, what had happened just prior was worse. Why hadn’t I just agreed to suck Ben off? He was right, I did enjoy it. But no, I had to resist, and yet again Ben took it to the next level. He was so strong, there was nothing I could do when he grabbed me, spinning me around. By the time I knew what he meant to do, his cock was already pressing up against my cunt!

Now who is the dog-fucker? I knew Ben was screwed up in the head, but I never thought he would fuck a dog right in front of another person. He’d even demanded Zack tape it. Imagine if that video got sent around school? Then people would know which of us was really the pervert!

But Ben didn’t seem ashamed in the least. Unlike me. I’d been horrified at first when Ben stuck his dick in me. I tried as best I could to weasel out of his grasp, but he was too strong for me. Zack wasn’t any help either, and by the time he protested, it was already too late. The feel of my former friend’s fat cock spreading my wet, swollen pussy apart had already infected my mind. He wasn’t bigger than the many dogs I’d had, but he was almost as long and the same width throughout, instead of tapering. I felt like I had a steel rod up my cooch, pounding up against my clit.

I shuddered then, for two reasons. I was disgusted and violated, being raped by Ben in front of Zack. I couldn’t help but watch my brother rubbing off to me, heat rushing to my face. How could Ben do this? Sure, the fourteen-year-old had made me suck him off a dozen times, but this was different. Ben Hendricks would now always be the first human I’d slept with! I wonder if I’m his first female ever.

As much as I hated Ben, furious that he’d now started to involve my brother, I also shuddered from sheer pleasure. The wet smack, smack, smack of his thick cock spreading me apart again and again made me hump and moan, my body just as horny and eager for Ben as for the many dogs who’d sampled my wares. To my everlasting humiliation, I came before Ben, trembling in his arms. I clenched down hard around him, my hips flying this way and that, whimpering and desperate to feel him shoot his load deep inside of me. My pussy lips squeezed and massaged him until finally I pleasured my captor enough that he could hold back no longer. With a splurt, he gave me exactly what I wanted - what I needed - a hot dose of cum.

With no knot to tie me, when he was done with me, he just pushed me away. I barely lasted two seconds before I curled up into a ball, searching frantically for every last drop of his seed that I could manage to reach with my flexible tongue. If I thought the flavor was addictive before, now, mixed with my own juices, it was ambrosia! I slurped and slobbered until nothing was left, well aware that my brother was getting off to it.

And now Ben was ordering me to clean my own brother up. Zack’s mouth hung open as he looked at me, and despite myself, I licked my lips. Ben’s orders would have made no difference - I needed to lap up Zack’s cum. I started moving, while Ben’s hand grabbed the camera.

I hustled over to the twelve-year-old, my mind revolting the whole time. This is your brother, Derek. What are you thinking!? Over and over, I commanded myself to stop walking forward, but just as often I ignored myself. I was already drooling, eyes fixed on the sticky, white goo. It had to be magic; there was no way I would feel this way about Zack.

Zack, of course, had no idea Tinkerbell was really his older brother. He stayed put, dumbfounded as I stopped in front of him, managing to hesitate only one second before I reached out with my large, soft tongue. Zack gasped as I wrapped my tongue around his half-erect cock, searching every inch for any spare droplets. Then, the younger boy moaned, placing his hands on my head. I laid my ears back, blushing harder than ever as my brother directed my snout around his stomach, pointing out every last blob. So gross! I thought, but I devoured every delicious morsel.

I turned to his tip, last, where one last bead of cum rested. I engulfed his cock from the base up to swallow the last, but by the time my tongue had come away, another drop appeared. Zack groaned and said, “Owww.”

I didn’t care. I licked again, savoring the salty musk of his cum. Now Zack clumsily pushed me away, but in the swiveling chair, his movements weren’t effective, and they didn’t deter me at all. I simply chased the tip, licking needfully again and again, the boy’s dick hardening in my mouth.

“Hey, Tinkerbell, stop!” he yelped, finally pushing me away. But he was already rock hard again, his dick and stomach smooth and wet, as much as the extra attention caused him to wince.

Ben, who’d been filming the whole thing, set the camera up and then got up. I didn’t even notice him until his arms were around me and he flipped me onto my back on the bed. I whimpered, but he hopped on the bed, holding me down by my chest. “Ready for your turn, Zack?”

Oh no, no, no. No. Ben had positioned me with my rump up against the edge of his bed, my slender hind legs dangling uselessly up in the air, and my wet, abused pussy pointing straight at my brother. I wished I could control my spade - it was bouncing like an eager bitch in heat, which I guess was a little more than half true. Zack knew enough about dogs to know what that meant.

“You’re kidding...” Zack said, his throat sounding dry.

“C’mon. I hit it. Look how much she wants it!”

I whined, but how could either of them tell the difference between a whine of horror and one of lust? Especially when my tail was wagging of its own accord?

“But I’ve never...done it before,” my brother protested.

Ben just scoffed. “It’s just a dog. She doesn’t count.”

I shook my head frantically. I was not about to get fucked by my own brother! He wasn’t really considering it, was he? I was a dog for God’s sake. Ben might be a perv, but not Zack. Not my little brother...

“You won’t tell anybody?” Zack asked. Why is he even asking!? “Turn off that camera,” he said, pointing to it.

Ben said, “Come on. I swear. Besides, I’ll be on the tape, too.”

Zack paused. He’s really considering it! How drunk did he get? He wasn’t slurring any words anymore... I shook my head back and forth even harder, but my brother didn’t even notice. He was too busy looking between my legs. “This is crazy,” he said.

Yes, it’s crazy. You aren’t going to fuck a dog. You aren’t going to fuck your big brother!

Ben said, “Yeah, you’d be crazy to pass up a free piece of tail.” He chuckled at his own joke, and then said, “You’re not gay, are you?”

“What? No!” he protested, getting up and pulling off his shirt so that all he was wearing was his socks. “I’m doing it.”

I dropped my jaw, frozen in shock as I looked up at Zack, his eyes scanning up the length of my body before stepping forward. This can’t be happening!

Ben leaned down to whisper in my ear. “Here he comes, Slutpuppy. I bet you’re really going to like this.”

I tried desperately to close my legs, but Zack pulled them apart, lowering himself until he was straddling the edge of the bed. The cock I’d just slurped back to life lowered to my waiting cunt. I shivered in horrified anticipation, knowing that there was nothing I could do. Thanks entirely to Ben, my little brother was about to lose his virginity...in me.

Zack paused, his hands resting on my chest. Thank God. He’s finally realizing that he’s just twelve, that he’s too drunk to be considering something so irreversible, that he’s naked in front of perhaps the most horrible boy in the entire school district, that his parents don’t even want him watching porn, that his cock still hurts from cumming so recently, that I’m a dog, God damn it, a dog! He couldn’t know that the bitch beneath him was actually his brother, but there were a thousand reasons for him to turn back now. The entire world seemed to be holding its breath as he hovered there, saliva-coated dick brushing up against my puffy lips.

“Well?” Ben said impatiently, pinning me tightly to the bed.

He’s not going to do it! He’s not going to do it!

“I can’t believe I’m doing this...!” he whispered, incredulous, and just like that, he pushed himself inside of me.

I yelped as my brother’s dick slid smoothly into my silky, soaked spade. His body met mine, resting heavily on top of me as our chests rubbed against each other. I spread apart easily for him, until with a splorch! he hilted himself inside of me. I trembled beneath him as he held himself there, feeling Zack’s balls resting heavily on my tail. He was panting heavily, content to just experience the hot vise of my cunt around his virgin cock. “Oh my God, Tinkerbell,” he winced, and I could tell that alongside the pleasure, his oversensitive cock was burning. But that wasn’t about to stop the pre-teen.

He wrapped his arms around me and began to thrust, dragging my quivering passage back before plunging in again. The rolling motion of his hips sent my splayed hind legs waving back and forth in the air, but it was his cock I felt most. He wasn’t as big as Ben, but in this position, his erection seemed to poke up against my clit even harder than when Ben had taken me, and though I was mortified, I couldn’t help but let out a high-pitched whine and being to hump up against my younger brother.

Ben let go, knowing that his job was done. Even if I wanted to squirm out of this situation, the half-drunk, horny tween wasn’t about to let me go. He moaned and speared me again, my tail thudding back and forth between his legs, brushing against his balls. I had cum for Pancakes. I had cum for Beefstick. I had cum for Samson, and for Sarah. For all the dogs at the trainyard, and even the wild wolf. Even Ben. But no, never, not my little brother!

I just have to hold out long enough. Gritting my teeth, I tried to pretend I was somewhere else. I tried to think of fat guys at school, of my own mother. Anything but Zack! Surely, I could outlast him. He was just a kid, and a virgin at that. He’d spend himself in me and that would be it. I could live with that.

Zack began to pull back almost all the way, just his tip buried in me before sliding smoothly in. I was forced to endure the full length of his cock grinding up against my clit, but I wouldn’t give in. His hands began to roam my chest, rubbing my teats in a way that sent tingles throughout my body. I bit my own lip until it began to bleed, trying to focus on the pain.

My resolve began to slip when he leaned forward so hard that he pressed up against my inner-most walls. Against my will, my hips resumed pumping up and down, jerking his cock up and down rapidly. He was sweating now, the musky scent of his adolescent body wafting up to my nose and triggering all the wrong feelings.

He hugged me again, gripping me tighter as he pounded me. Our eyes were almost level and I saw that his were half-lidded in his ecstasy. Surely, he can’t last much longer! I blinked, realizing suddenly that my paws were wrapped around my brother’s back.

Next to go was my voicebox. I gritted my teeth, but the moans and groans still escaped. I could feel the almost painful heat building up in my loins, growing every second that Zack was inside me. Why was I whimpering? Was it instincts or magic? Or simply pleasure?

Glancing over, I saw that Ben was on the camera, watching us with a grin. I blushed furiously, thankful that he couldn’t see it through my fur. With a little editing, he’d finally have proof that at least one of the Smith brothers was a dog-fucker. I wondered idly how long he would wait before posting that video on Facebook. Zack, you shouldn’t have trusted him...

Yip!

A particularly rough hump brought me back to the present. My brother was panting heavily, his face only inches from mine. I reveled in his scent, tail wagging as I whined pitifully. Ben had hardly lasted three minutes, but Zack was easily on his fifth minute of plugging me! If only he hadn’t cum so recently. I don’t think I can hold off for much longer.

“Oh, Tinkerbelllll!” he groaned, but still he didn’t cum. I simply couldn’t take it anymore. When he opened his mouth in a moan, I couldn’t stop myself. I plunged my tongue inside, wrapping it around his. Zack’s eyes popped open in shock, but he closed them again, moaning and returning my kiss. Oh God, I’m Frenching my own brother!

We made out frantically for ten seconds before I finally lost it. Zack slammed into me and my entire rear end dissolved into mindless humps and clenches, a wave of shudders engulfing my small body. My howling moans were muffled by my tongue curled up inside his mouth. Squirting, I came hard around his cock, helplessly lost in the bliss of sex. Despite my best efforts, I howled submissively underneath my own brother.

My clenching cunt finally triggered Zack as well. He pounded down onto me, resting his whole hundred-twenty pounds on me as his virgin cock began to twitch and splutter. I whimpered as he claimed my magic-cursed form, wrapping all four of my legs around his sweaty body. I watched dully has Ben caught it all on camera, even going so far as to bring the camera phone in for a close-up between my oblivious brother’s legs.

For the second time that night, I climaxed helplessly as a boy flooded my womb with hot streams of cum. It felt so good - so right - to have my brother in me that all I could do was rock my hips and reach up to ram my tongue once again into his mouth. He let me in eagerly, muffled groans accompanying his eager slurping. Whether he could taste the remnants of Ben’s or his own cum from my tongue, I couldn’t say.

Still, he was just a twelve-year-old boy, and he’d already spent one load to boot. He only lasted a few blissful seconds before collapsing completely, pinning me to the bed. I kept my legs around him, blushing furiously as I lovingly embraced my brother in a way I would never have predicted. Ben knew what he was doing when he raped me. Zack was just doing what he could to help a horny bitch in obvious need.

Finally, he broke our kiss, groaning as he pulled his sensitive cock from my tight, warm pussy. I whined again, this time from the loss and emptiness I felt, knowing that tomorrow, I would once again be at Ben’s sole discretion.

Zack said, “Oh fuck, Ben, what did I just do?”

“Pretty good, huh?” the older boy said, grinning.

Zack wrinkled his brow, pausing with a cute blush before saying, “Yeah.”

Kerthud!

A door slammed downstairs, and Ben said, “Oh, fuck! Sarah’s home. You’d better get out of here and sleep off that booze, or we’ll both be in deep shit, Zack.”

Zack’s eyes bugged out and he grabbed for his clothes, running for the door as fast as he could. I watched him go, laying my ears back, still panting and wagging on the bed. I’d been gone from home for over a week now. Despite what had happened (or perhaps because of it), it was really good to see Zack again. If only he could stay…

* * * * *

“Zack!?” I shouted, incredulous at the sight of the neighbor kid leaving Ben's bedroom.

The eleven-or-twelve-year-old boy was standing awkwardly in front of me, face red and wearing his shirt on backwards. I could clearly smell alcohol on his breath, though he only seemed a little buzzed. What on earth was my little snot of a brother doing? Maybe he thought drinking would help Zack cope with the disappearance of his brother, but I doubt the reason was anywhere so nice as that.

“Sorry, Sarah,” he mumbled. “Please...don't tell my parents!”

“Did my brother do this to you? I should really give that idiot a piece of my mind!” I yelled, walking toward the door.

Zack was surprisingly quick – he'd been drinking, but seemed to be alert—enough to stop me, at least. He stepped in my way with his hands palm up and said, “Don't go in there! I mean, it wasn't his fault. Really.”

I eyed him suspiciously, and he stared me straight back. “Alright,” I sighed. I mean, I couldn't help but feel sorry for him, with his brother running away (or worse) a week ago. I wasn't about to let Ben off the hook here, but I had to take care of Zack first. “Come on, let's get you home.”

When we got outside, I peered over the fence. Shit, the Smiths are in their dining room. “Okay, Zack, here's how it'll go. I'm going to head to the front and ring the doorbell. Offer my condolences.”

I could see the hurt in the young boy's eyes as he thought of his brother. Why'd I have to go and remind him? I carried on, “While they're at the door, you sneak in the back and run upstairs. Take a shower and use some mouthwash, and they'll never know anything happened, okay?”

“Yeah.”

I turned to leave, but he spoke again. “Sarah?”

I raised an eyebrow at him. “Yeah?”

“Thanks.”

The plan went off without a hitch. Better, even; it seemed like Mr. and Mrs. Smith really appreciated the gesture! But I spent the whole time thinking about Ben. When I finally got free of Zack's parents, I stormed straight home and up the stairs and kicked his door open with - what would Mrs. Kahoteck say? - aplomb.

Ben must not have heard me, because he swiveled around in shock and yelled, “Sarah!” as if I were violating his human rights. He was in his underwear and socks, tossing his phone onto the bed before covering himself up pathetically with his hands. As if I'd never seen my brother walking around in his tighty-whities before. I just shrugged it off and got to the point. “What the hell were you thinking!? Where'd you get the booze anyway?”

Ben growled. “Did you ever stop to think that maybe it was Zack's booze? I was just trying to be comforting, alright?”

“Bullshit.” I was about to challenge him again, when I finally saw what he'd been looking at when I came in. There, in the corner, was Tinkerbell, cowering on the ground. She looked absolutely miserable! Stunned, I shouted, “What's wrong with her? What did you do, Ben?”

“I didn't do anything, bitch. Now get out of my room, or I'll tell Mom and Dad. You have no -”

A second glance at the dog told me enough. I didn't know what he was doing to her, but it was definitely something. I cut him off before he wasted his breath. “What, are you beating her, or what?” I demanded, stepping forward and pushing Ben toward his computer. I reached for Tinkerbell, but she came willingly, skittering past Ben to the open door. I glared at my asshole brother. “You're a monster!”

Ben said, “Give her back – she's my dog. Go ahead, look her over. There's not a scratch or a bruise on her.”

“No way. I'm keeping her safe until Mom and Dad get back.”

Ben lunged forward, but I was too fast, slipping out his door and closing it in his face. “Come, Tinkerbell!” I shouted, but she was actually way ahead of me, already in my room. I could hear Ben sliding in his socks behind me, too slow. I got inside and slammed my door shut, locking it with a kerclick.

Ben pounded on the door, yelling, “Open the door, Sarah, she's mine!”

I panted, “Not after Mom and Dad see how she behaves around you!”

“Just you wait and see,” Ben laughed manically. “She'll be a perfect little angel, unless she wants a certain video up on Facebook!” I heard him walk away from the door before I could ask him what the heck he meant.

It's almost as if he were talking to her, I thought. Had my brother finally lost it?

Sighing, I sat down on the bed, and said, “Here, Tinkerbell.”

The German Shepherd walked over to me, calm, but with her tail held low. I petted her, looking her over, but Ben was right – there wasn't a scratch on her. But I had seen the way she cowered and ran from him. “Up!” I said, patting the bed.

I was exhausted. First, a long, but fruitful date with Isaac, then all this business with the Smiths and then Tinkerbell. I just wanted to sleep. I lay back, only to find Tinkerbell curled up next to me. The rhythmic sound and pressure of her breath was surprisingly relaxing, and within minutes, I was out.

When I woke up several hours later, she was still there.

“Oh, Tinkerbell,” I said apologetically. “I'll get you away from him, I promise.”

As if in response, she licked my cheek. I couldn't help but smile and hug her. She seemed so real. So smart. It was like talking to Margie or Sarah #2, except the dog was a better listener. Looking into her eyes, hugging her, I could swear she was looking right back, nuzzling under my chin. Not to mention the intimate nights we shared. There was something special about Tinkerbell, and I could tell that Ben was trying to squash whatever that 'something' was as hard as he could.

* * * * *

“But Mom, I know what I saw! She was terrified of him!” Sarah cried.

I wish I didn't feel so much like I was betraying her. Other than Zack, Sarah was the only person I was really beginning to trust. But I couldn't do what she wanted. As much as I wished I could cower and whine when Ben approached me, I knew what would happen.

He'd ruin Zack's life. Every day that the threat of that video kept me cooperating was another day before everyone in school knew that Zack had fucked a German Shepherd. I sat quietly as Ben petted my head, smirking obnoxiously at his sister.

Mrs. Hendricks said, “Sorry, dear, but she doesn't seem hurt in any way, and she's just as happy as a clam with him, now. Ben must be right – your little argument must have scared her.”

“That's not what happened,” she insisted, growling and squeezing her fists so tight they turned white. “This isn't over...” she said to Ben before storming out of the kitchen.

“I dunno what's gotten into Sarah, Mom. You can see for yourself – Tinkerbell loves me!”

Trying my best to put on a doggy smile, I licked his hand, wagging my tail when he leaned down to rub my neck and back. Mrs. Hendricks probably didn't hear what he whispered in my ear.

"Frequently."

Chapter Text

Ben had his arms wrapped around my body and was lowering me rump-first into his lap. My tail thumped against his smooth chest - as much as I hated my new life, I couldn’t deny the sensations that washed over my body every time the fourteen-year-old claimed me. He didn’t make me suck him off anymore. Now that he had a soft, black-mailed fuck toy he took advantage at every opportunity. This morning, he woke me by grabbing me rudely from my sleep and pulling me into his computer chair with him.

My hind legs reached his thighs now, so I balanced tenuously there, whimpering at the now familiar feeling of his thick cock pressing up against my wet opening. More than three weeks had passed since my change, and I was still in heat. I became more and more convinced that my pussy lips would never shrink down and end the burning itch inside me.

Ben was the primary remedy for my trembling cunt. Sure, when he had time, he’d walk me to the railroad tracks and film me lifting my tail for every passing dog in the neighborhood, but those days became fewer and farther between, replaced by morning, afternoon and night beneath my former best friend’s warm panting body. I hiked my tail to the side, glancing over my shoulder as I lowered myself onto him.

He slid inside of me, making my voice quiver. Ben squeezed me tighter, clenching his eyes shut as he reveled in my tight pussy. Leaning forward, the heavy-set boy jabbed upward, spreading me wetly apart. I yelped, splaying my hind legs as best I could. His staff was long and firm, pinning my hindquarters in his lap. My eager spade massaged him, pulling him deeper before I lost myself in short, jabbing thrusts. Ben humped up into me in time, groaning noisily.

"Good girl.”

He ran his hands up and down my belly, rubbing roughly against my teats. They seemed larger and more sore - I might still be in heat, but I knew enough about dog-breeding to recognize the first signs of pregnancy. The only question that remained in my mind was how many of them would belong to Pancakes, Beefstick, or Samson. Thank God they can’t be Ben’s - I don’t know how I’d live with myself!

My whimpers turned to whines, which turned to howls. I slammed my hips up and down on his cock, tongue dangling from the side of my mouth. So good! I barked.

"Shush,” Ben commanded, pulling me closer. I snapped my mouth shut, muffling my frantic moans. Ben didn’t like it when I drew Sarah’s attention, much less his own parents. The boy’s sister still refused to believe that I would willingly subject myself to Ben, and she was absolutely right. But what could I do? He had pictures of my younger brother fucking a dog! Whatever Ben could do to me, he could do a hundred times worse to Zack with the press of a button.

Sarah got to walk me in the mornings, which I appreciated. However short, any break from Ben was a break worth having. The school week wasn’t so bad, but the weekend was about to begin again and I knew that Ben probably had some new terror planned for me. And Zack? I could see it in the way Ben looked at me, whistling nonchalantly. I knew well enough that the evil in that boy wouldn’t be quelled simply by my freely-offered cunt.

Ben slammed me down against his dick, poking me roughly against my innermost walls. My pussy split apart and squeezed up against his abdomen, hilted again and again by the horny teenager. I kept my teeth grit, even though Ben was groaning louder than I was. I let out a muffled whimper. It won’t be long now...

"Oh, Slutpuppy!” he cried affectionately, wrapping his hands around my slender waist and pulling hard. "Beg for it!”

I knew what he wanted. Dropping my jaw, I began to whimper madly, fast and high-pitched, digging my paws into his legs to push down harder against him. I clenched hard around his cock, bucking my hips insistently. I glanced over my shoulder with my tongue dangling, whining at him.

"Okay, okay,” he said smiling. "I’ll give it to ya, you horny little bitch!” Holding me around the chest with one arm, Ben grabbed the base of my tail with the other, leaning forward until I was dangling out over the chair. He held me there half-suspended and hammered forward, groaning loudly as he came.

Splurt!

Ben was no dog. When he came, it was one and done, splashing me once or twice before he dissolved into weak shudders. Still, I drank him eagerly, my own rump spasming uncontrollably around his twitching cock. What Ben lacked in duration was made up for in size - his penis was thick throughout, with none of the tapering that my new species was designed for. His hard flesh had a lot more give, vibrating against the source of that inescapable, intense pleasure. Saving Zack or not, if Ben couldn’t have made me cum, I don’t think I could have put up with him for this long!

I rocked and roiled in the teenager’s lap, howling softly through my tightly sealed lips. The itch was gone, at least for the moment, replaced by a warmth that spread less like a heater and more like an exploding grenade throughout my whole body. I flattened my ears, picking myself up and pushing myself down his trembling cock, knowing that I only had a few moments before the sensation was too much for Ben and he threw me off. I had to get what pleasure I could.

He lasted somewhat longer than normal, then pushed me off onto the floor, groaning. "That’s enough,” he commanded, shivering.

Still orgasming, I humped weakly against the air, feeling so empty. Curling up, I filled the void with my large, wet tongue, splaying my pussy apart in a desperate search for every drop of cum. The flavor was enough to egg me on, but the feel of my tongue pumping in and out of my cunt kept me cumming for several blissful moments before the moment passed and I was just normal old Derek again.

Just Derek, trapped in a body he was never meant for. Trapped at Ben’s beck and call, with absolutely no hope for escape. My cheeks burned, realizing that the best part of my day - the moment I looked forward to - was when Ben ordered me to fuck him. It was Saturday morning, and I would spend it waiting desperately for the boy I hated more than anyone in the world to recover and fuck me again. When I whimpered again, it had nothing to do with my tongue in my heat-swollen mound.

"Good girl,” he repeated, knowing that the false praise didn’t get to me anymore. I could watch the gears moving in his head, until he settled upon, "I saw your brother yesterday, in the backyard. He was playing with Brian...Markley, I think? He seemed happy, moving on. Getting back to a normal life.”

I glared at Ben, seeing right through him. The threat was clear enough, but Ben Hendricks was never a very subtle person. "You keep being such an obedient dog, and it’ll stay that way.”

I nodded slowly, pulling my tongue free with a wet slorp! Ben smiled, took a deep breath, and said, "Damn, I gotta take a shower after that.” He got up, grabbed a towel, and left the room, leaving me alone on the floor.

What did I do to deserve this life? Thinking like that was pointless - I’d done nothing. I was just the boy unlucky enough to fall in Ben’s crosshairs. I’d thought that calling me a "dog-fucker” in front of the entire school was bad enough, but I had no idea the depths he would sink to when he had absolute power and no consequences. He was going to sink lower today, I just knew it. All I could do was hope that Ben’s plans didn’t involve Zack.

And that’s when I saw it lying on the bed.

Ben’s phone...!

He kept it close at all times, not wanting the phone to fall into his sister’s hands. Sarah was actively looking for ways to sabotage her brother now - she’d said as much to Tinkerbell on their walks. If I could just bring this phone to Sarah, she’d have all the evidence she needs to convince her parents that Ben was abusing me - though not in the way she expects.

But she’d find evidence of Zack abusing me, too. That damned video! Blinking, I rushed over to the iPhone. Concentrating, I placed the very edge of my middle claw on the power button. It better be charged! To my relief, the phone sprang to life with a bright glow. Claws couldn’t activate the touch screen, so I had to press my paw pads to the buttons, but with the large icons, it wasn’t as hard as I expected.

Camera, to Video, to Recordings. There I saw it, all the evidence of my shame. There were over 50 videos now, mostly of me getting reamed by stray dogs in the yard. Most of those videos were online now, according to Ben. He even read me some of the disgusting comments people left on his page. But two of the videos featured only me, Zack, and Ben. I shook my head sadly to see the still frame of Zack approaching me as Ben held me down on my back. I had to remember that my brother was drunk, and Ben had egged him on.

I could easily hear the shower running in the distance. I had plenty of time. Carefully selecting my brother’s image, I tapped "delete”. I tapped confirm, and thankfully, the phone didn’t ask me for Ben’s password. I panted in relief watching the phone think as it deleting the incriminating evidence forever. I sure hope Ben was too stupid to make any backups.

It’s done. He can’t control me anymore. I’ll run to Sarah, and she’ll protect me. I’ll never have to suffer by Ben’s hand or cock again. I’m free!

Adrenaline rushed through me, so excited I didn’t even notice Ben entering the room behind me. He didn’t have to take too long to piece together what had happened, ‘his’ dog dancing around the iPhone. But what did it matter? He couldn’t hurt Zack anymore!

"GET AWAY FROM THAT!” he shrieked, shoving me aside and crouching next to the phone. "Bad dog!” Ben cradled the phone in his hands, quickly scanning the videos. Turning toward me with eyes burning, he said, "You deleted it!”

I backed up to the open door, knowing that Sarah was still in the house in case Ben got nasty. I didn’t run - not yet - because if ever there was a time to gloat, it was now. The only thing Ben’s videos could show now was that he was a huge pervert. I was done cooperating - cooperating is what got Zack into this mess in the first place! I gave the fourteen-year-old a toothy unmistakable grin, wagging my tail.

Ben didn’t chase me down. He didn’t attack me. He didn’t even scream at me.

What he did do made my tail and ears droop, and I felt a shiver straight to the bone.

He smiled.

* * * * *

That fucking bitch! I thought, trying my best not to show my shaking hands. I’d been so sure I’d turned Derek into my very own, submissive little cock-warmer that I’d slipped up and lost Zack’s video. At least the other recordings were intact. I hadn’t uploaded them yet, despite what I’d told Slutpuppy, but I sure as hell was going to now. Tinkerbitch needed to be punished, and I needed some more leverage. How could she do this to me!?

I smiled at Tinkerbell, not willing to show my anger. She was a pretty cocky dog for someone with no cock! I walked over to the mini-fridge, still looking straight at the bitch, speaking softly and clearly. "I may not have that video anymore, but Zack doesn’t know that. I think him and me’ll take a little walk, whether he wants to or not.” I emphasized my point by pulling the little bottle of Love Potion #10 from the false back of my fridge. There was still more than half a bottle.

The dog’s eyes went wide. "Yes, I think it might be time for your brother to ‘run away’ from home.”

I’ll admit it, I was surprised by her reaction. The small German Shepherd charged me, baring her teeth. Now that’s the kind of reaction I was looking for! Setting my legs, I closed my hands around her head, stepping aside to pin her against the bed. Reaching out to my nightstand, I grabbed something I stole from the pet store the day after I got ‘her’, just in case - a muzzle. Tinkerbell struggled as I held her mouth shut with one hand, wrapping the muzzle around her with the other.

She kept struggling, but it was useless. She couldn’t even make enough noise to draw Sarah’s attention now. Panting a little, I said, "Don’t worry, I know just the place. And you can watch!”

She finally stopped struggle and just whimpered. I clipped the leash to her collar. "If you don’t think I’ll go through with it just because I can’t control you without Zack, think again. I’ve got plenty of potion. I’m sure your mom really misses you - perhaps she’d like to be tied up at the train yard with you? Or maybe I’d keep her all to myself, to keep her dog cunt nice and tight.”

That shut her up. Tinkerbell was trembling now, no less than she deserved for betraying me like this. I got dressed quickly enough, tucking my iPhone in my pocket before grabbing her leash. "Ready for walkies!?” I asked.

She followed me easily enough, not even trying to scrape off the muzzle. She knew when she was beaten. If she didn’t obey, I could systematically destroy her whole family. Still, the thought of fucking Tinkerbell’s mom right in front of her was pretty appealing. Maybe next weekend...?

I headed downstairs, grabbing the phone and dialing Zack. He picked up, sounding groggy. "Hey, Zack! I think you’d better meet me out back. If you know what’s good for you.”

Tinkerbell whined, but I pulled her along roughly, heading into the backyard.

Zack said, "Wha -”

"Outside - now!” I yelled, pressing "end call” with a flourish. I only had to wait in the chilly air for three minutes before Zack came tumbling out the back of his house, hair still a mess and in baggy clothes.

He couldn’t see Tinkerbell at my side thanks to the large, wooden fence, but that was just as well. He raised an eyebrow at my smile. Might as well get right to the point: "You know last weekend when you came over?”

Zack gulped. "Uh...yeah?”

"Well, I had a certain...video recording on my phone that I’ve got sitting, ready to upload to Facebook. That is, unless I stop it in...3 hours or so. So I was thinking you and me and Tinkerbell might go for a little walk together.”

Zack’s mouth gaped open stupidly. I’d always thought the younger brother was smarter than the older - he certainly had more friends at school - but maybe I was wrong. "Get moving!”

The twelve-year-old blinked. "Okay, okay!” he said, following me as I opened the gate to the train tracks. He ran to catch up, while Tinkerbell looked up at her brother and whimpered. Zack asked, "You - you wouldn’t really...”

I glanced at him, walking at a brisk pace. "I don’t want to, Zack, but I won’t have to if you cooperate with me. Okay?”

"But...but you told me to! I was drunk, Ben, I didn’t know what I was doing...”

I laughed. "Only I get to fuck Slutpuppy. But don’t worry, I only want one, simple thing, and then I promise I’ll delete that video forever, okay?”

Zack nodded, looking down at his transformed brother. "Why’s she wearing a muzzle?”

I turned the corner, dragging Tinkerbell along beside me. Not far now... "She’s been a bad girl. Now come on and hurry - the three hour clock is ticking!”

I jogged the rest of the distance, Zack easily keeping up. He was a lot fitter than his ‘brother’ used to be. Finally, there, along the railroad tracks - Zack’s final destination. A three-railed wooden fence separated 15 enormous horses from the tracks. I used to come here when I was younger, to an equine stud farm within walking distance. The summer was the best time, when all the mares went into heat. The breeders either didn’t notice or mind that I was watching from the tracks. It was too cold now for most mares to be in season, but I had a little bottle in my pocket that said the stallions here were about to discover a tight and warm (if unwilling) piece of tail.

"What are we doing here?” Zack asked, still shaking.

Tinkerbell started to struggle again, knowing exactly what I had in mind. I tied her leash around one of the fence posts. "You are going to squeeze through that fence,” I said simply.

"With that horse in there!?” Zack exclaimed, looking the creature over. A big, black stallion with a slightly warped diamond on his forehead; I knew him well. He was old now, but the breeders still brought him out to stud more than any other stallion. I think his name is "Blackie” but I called him "Reamer” on account of what he did to the mares they gave him. I couldn’t have asked for a better, larger, stronger stud to introduce Zack to his new life.

"He won’t hurt you. Get inside.” Tinkerbell was trembling, frozen in place, knowing what she was about to watch. She’s mine now; she’ll never cross me again after this.

Zack thought over his options, but he really didn’t have any. He didn’t know that Slutpuppy had deleted the video. How could he? The twelve-year-old cautiously slid through the top and middle rails, keeping an eye on Reamer. The stallion wasn’t interested. Yet.

I took out the bottle. I hadn’t bothered to mix the potion in with Gatorade this time, since he’d have to drink it. The glass bottle was still more than half-way full. The label said, "Love Potion #10”, but Zack would have no clue what it really did. I offered it to the boy, saying, "Drink a gulp of this, then look at that horse or the whole world will know that you’re a dogfucker.”

Zack reached out to grab the bottle, miserable as a beaten dog, but it never reached his hands. The German Shepherd had too much give on her leash. She darted beneath the lowest railing, smashing straight into Zack’s legs. "Hey!” the boy yelped, dropping the bottle of potion.

I watched in horror as the old bottle fell, as if time were slowing down. It spun two times in the air before landing in the mud and horse manure with a thud. My heart was racing. It didn’t break!

Zack looked down in confusion, only for Tinkerbell to leap onto the bottle. The muzzle stopped her from grabbing it, but she placed her little paws on the bottle, growling up at Zack.

"What’s going on with her?” Zack asked, quickly checking to make sure Reamer wasn’t up to anything dangerous.

"Thinks it’s a chew toy or something. Get it!” I yelled.

"She’ll bite me!” Zack said, looking down at the bristling dog.

"She’s got a muzzle on, idiot!”

Zack looked sheepish, but knelt down gingerly, nonetheless. I underestimated Tinkerbell again, though. As the boy knelt, the dog spun the bottle, then pointed with a single claw at the label. Zack read it out loud, "Love Potion #10 - Madame Ruth’s Magic Shop, 1135 Broa -”

"Just shut up and drink it!” I shouted. When Zack didn’t make any moves, I knew I had to take matters into my own hands. I slid through the fence, ready to grab the bottle and stuff it down Zack’s throat.

"Why? What is this all about? Why is Tinkerbell acting so strange?” Zack said, taking a big step backward, warily.

I kicked her hard in the ribs, making the seventy-pound shepherd yelp and cringe away.

"What are you doing!?” Zack yelled, aghast.

I grabbed the bottle, eyes flashing as I reached out to grab Zack by the collar of his shirt, pulling the smaller boy close. Popping the cork with my other hand, I said, "Drink this, you fucking faggot.”

I heard feet padding in the mud and glanced down to see Tinkerbell launching herself toward my legs, only to be jerked back like a rag doll when she reached the end of her leash. She couldn’t save him now. Grinning at her, I turned back to Zack and -

Zack was spinning, lifting his arm in a wide circle until he wrapped his arm around mine. He kept turning until my grip on his collar couldn’t hold anymore, and I let go against the pressure on my arm. He was still spinning, back turned to me, so I never saw his elbow coming until it smacked me in the side of the head. I staggered backward, desperately gripping the potion so I didn’t drop it.

Cute move. I guess they actually taught something at those karate classes. I still had forty pounds on the little fucker, and I wouldn’t underestimate him again. I stepped forward, arms up to protect my face. It might have worked, too, if I hadn’t backed up into Tinkerbell’s range. The German Shepherd grabbed my leg and pulled in a very undoglike way, pushing me off-balance. Spinning, I grabbed the nearby fence to slow my fall, but when I tried to stabilize my other foot, it slipped in the manure and I went falling down with my back to the fence, hitting my head against the fence post.

Everything seemed foggy for a few seconds, the pen a blur of brown and black. Was that Reamer? I lifted my right hand to see the bottle of potion, panting heavily. It hadn’t spilled. Oh, thank God -

Zack was next to me, his hand under mine. Before I could react, he pushed the bottle to my lips, tipping it into my open mouth. I felt the cool gush of liquid on my tongue before I could pull it away. Sputtering, I spat out everything I could, tossing the bottle aside. Don’t swallow, don’t swallow!

"What did you do!?” I yelled, looking up. But it wasn’t Zack I saw - it was Reamer, watching warily from the back of the stables. I shut my eyes tight. I didn’t drink enough, and I didn’t see anything, I thought to myself I just have to get out of here and come up with another plan. I kept salivating, trying to wash my mouth out as I spat on the ground.

"I don’t know what the hell is going on,” Zack said, standing a few feet to my side. "or what you put in that drink, but I’m not drinking it.” The preteen’s voice quavered, and he continued, "And you are not keeping Tinkerbell. You can’t just kick a dog! I don’t care what you do with that video; as far as I’m concerned, you can go fuck yourself.”

He still has no fucking clue. Even after all the strange shit ‘Slutpuppy’ has done, he still thinks she’s just a dog. I’d laugh if I weren’t trembling in fear. It is fear, isn’t it? Eyes clenched, I felt like throwing up right in the mud. Was trembling how it started?

"Well...? What do you have to say for yourself?” Zack asked in a huff.

Nothing happened. I let out a huge gasp, starting to breathe again. Absentmindedly scratching my arm, I looked up at Zack, relief fading into anger. "You little motherfucker!” I yelled, driving my fingernails into my arm. Why did it itch so badly? I glanced down only to see bright, white hairs growing out of my arm. Eyes wide, I said, "No, no, no, no, no! Not this...! This isn’t happening!”

Zack could hardly understand the sudden change in tone, saying, "Wait, what?”

Sure enough, it was all over. I watched the hair - no, fur - spreading up my arm. I’d only tasted a few drops, and drunk even fewer, but that was enough. I’d been getting up, but I sank back to my knees, a dull ache in my stomach. I glanced over at Tinkerbell, who watched, seated in silence. She wasn’t gloating - it was far worse. I wasn’t imagining it, the look on the damned dog’s face was pity.

"Fuck you,” I said, staring straight at her. "This is all your fault, you know that?”

"What the hell is going on?” Zack cried, alarmed now as he watched my hands start to clam up, fingers visibly shifting.

I didn’t fight it. I was turning into a horse and there was only one person who could save me. I spoke quickly, but my voice lasted long enough anyway. "Zack, please, you’ve got to help me. Go to Ruth’s...the magic shop!” I yelled, mind rushing for the fewest words with the most effect. "On Broadway. Tell her to change me back!”

I didn’t know if it was possible. The instructions had said the potion was permanent, but maybe with such a small dose... I didn’t know whether Zack would even try. How soon before he realized what I was planning to do to him? How soon before he realized who Tinkerbell really was? I slumped down, knowing it was hopeless. I closed my eyes, waiting for the change to finish. There was nothing more to live for, the worst that could happen to me had already happened.

I don’t deserve this!

Snort! The rich, deep grunt caught my attention. Looking over my shoulder, I saw Reamer and realized that the worst was yet to come! Like with Derek, the potion was changing me into the most appealing form for Reamer. What was I doing!? I had to get out of the pen, now! On my hands and knees in the manure, I scrambled for the fence. I was not about to let myself get stuck in the pen with that fucking monster!

Zack took a step back, watching me crawl pitifully through the mud. The idiot said, "What are you talking about!?” My hands were already shrinking and molding together into hooves, and my legs weren’t far off. Combined with the sticky manure, I barely made any progress. The fence was just a few feet away, but it seemed like a mile.

I might have made it anyway except for another oversight on my part. I’d forgotten about my clothes! My chest began to expand and change shape, stretching my shirt into a wide bulge. The shirt was nothing compared to my blue jeans, though. The strong fabric creaked, holding in my thickening legs. My feet were getting wider, thicker and shorter, tearing holes in the seams of my shoes. Every part of me hurt!

"Oh, God, oh God!” I whined, reaching down with my hands to try to unbutton my pants. Not an easy feat when your fingers were curled into a fist and wouldn’t open. I could see my fingertips merging with my palms, leaving me with big, useless clubs. I felt the fabric tear, my ass getting fat and wide. Desperately, I fumbled with my shirt, trying to kick off my shoes. I managed to toss the t-shirt over my head, but my misshapen feet were locked inside the bulging sneakers.

"Oh my God, Ben! What do I do? What do I do?” Zack gasped, watching the unbelievable. Tinkerbell watched quietly from behind the fence, knowing there was nothing any of us could do.

"Madam...Ruth!” I grunted, finally feeling my jaw begin to shift. My teeth were growing, my nose pushing forward. The change itself didn’t hurt, but my jeans were like a special kind of torture. But the denim couldn’t hold me back forever. My hips still had a lot of growing to do. I had to admit I was grateful when the pants finally ripped, rolling down my legs in tatters. There was almost nothing left of my underwear.

Now only my lower legs and feet were covered, so Zack could see everything that was happening to me. I tried to crawl forward, but the tight remains of my pants tripped up my back legs. My arms were growing thicker and longer, barely responding to my demand to flee. If there’d ever been any doubt about my transformation, it was now gone.

"You’re turning into a horse!” Zack cried. Well thanks, Captain Fucking Obvious! My chest was growing in every direction into a thick, white barrel, but that wasn’t what concerned me the most. I’d known it would happen from the moment I began to itch, but I still couldn’t rip my eyes away. Trembling, I looked down my body to watch my growing legs, and what was happening between them.

"No-o-o-o!” I bleated, my throat constricting. There it was, my pride and joy, still sore from fucking Slutpuppy, but my fat cock wasn’t growing. Why couldn’t Reamer have been gay? Instead, I watched my dick shrinking. Zack was watching too, jaw dropped. I shrank away like I was dipping in cold water, but it kept going. At the same time, my balls pulled up and out of sight, and two soft mounds began to sprout from my abs. I yelled again, but my stretching snout only let me whinny.

"Hey, help! Help! Someone!” Zack called, looking around. But it was Saturday, and no one worked at the yard. What could they do, anyway? I reached down with a glossy, black hoof to poke mournfully between my now empty legs. While my rump grew in all directions, I felt the remnants of my cock splitting apart, something stirring deep inside me. I was halfway there, now, almost a filly.

Now Reamer was interested. I heard heavy footfalls in the mud behind me, the stallion nickering as he watched my changing hindquarters. While one shaft fell away, and another sprouted just above that. A thick nub of flesh poked out from my spine, brilliant white hair spilling off of it into a long, wiry tail. I glanced over my shoulder, trembling. I knew that look from many years of watching Reamer do his work. He was hungry, and I was his meal ticket.

I have to get out of here! Shivering, I leaped forward toward the fence, tripping on my torn jeans and falling face first in the mud. I must have fucking looked like an Almond Joy, my fat, white body covered in brown horse shit. Mounds, I subconsciously corrected myself. I didn’t have any nuts.

My shoulders had shifted, locking together so that I could only move my arms forward and back. My elbow was swollen and white, and I struggled to stand uselessly. How do horses get up? I kicked and kicked, squirming in the mud, until finally my jeans came off. My shoes were torn apart nearby, leaving me completely naked. I might have been cold, except for the thick layer of pure-white fur even now spreading up my neck.

My neck itself was spreading! As if crawling forward wasn’t hard enough, I felt my neck thicken and stretch, curving as it lengthened. For a moment, it appeared as though the fence was getting closer, and my heart leapt - but it was just my head and face growing outward, eyes pushing further apart. Straining, I looked down, trying to gasp when I saw that my barrel was too thick to go through the fence slats now. The only sound that came out was a snort.

Zack watched, frozen. I guess I couldn’t blame him - I didn’t leave until Derek’s show was over, either.

The gate was tied shut with a heavy, metal lock. There was only one way out now - over. How could I think to jump the five foot fence when I couldn’t even stand? Still, I had to try. If I stayed in the pen with Reamer, he would have me. I’d seen personally how he treated fillies that fought him. Gritting my thick, white teeth, I concentrated on the first step.

Squirming forward, I planted my front hooves on the ground. My shifting hind legs were stretched out awkwardly, so they’d be of no use. Struggling with my new muscles, tried to push myself up with just two legs. My elbows wobbled, but my front half was too heavy for that, and still getting heavier. All remnants of my humanity were gone now - all that was left was growing into my new body. I must have been three-fourth’s full-size now, like a pony compared to Reamer, who was a full-sized thoroughbred.

Like a lightning bolt, I suddenly remembered how horses get up. Was my brain transforming too? I didn’t question the newfound memory any further, I just sprang into action, rolling over onto my right side. As quickly as I could, I whinnied and tucked my back legs to the side, swiveling my upper body back into an upright position. Now I could do it. Tossing my front hooves out in front of me, I tensed my muscles, pushing upward just as hard as before...

But this time, my back legs were ready. With a leap, I got my left leg beneath me, wobbling as I pushed with all three limbs. For a moment, I seemed set to topple over, but I finally found my fourth foot. I was up! I whinnied triumphantly.

"My God, Ben...Ben, you’re a horse.”

I gave the twelve-year-old a look, though I don’t know if he could recognize a cross quarter horse. The transformation was complete, and one way or another, probably permanent. I was significantly shorter than Reamer, almost a foot at the shoulders, and my pure white fur might have been beautiful if my belly and right flank weren’t caked in manure. I’d always suspected that the stallion took a certain pleasure in ramming his cock into the tight little snatches of small fillies; now, as his ideal mate, I knew it.

"Are...are you still in there?” Zack asked like a moron.

I wanted to kick the bratty little bastard, but I didn’t have enough time. Instead, I tossed my head up and down. But I had a fence to jump, and I could hear Reamer’s heavy footsteps approaching from across the pen. Tossing my head, I tested my legs. I built up a pretty good speed, though I stumbled a bit at the canter. How do horses remember all these different ways to run?

Knowing Reamer was coming for me, I ran with my right flank to the edge of the pen, running in a wide circle. Sure enough, I could see the large, black thoroughbred trotting toward me. Snorting, I picked up the pace, giving the horse a wide berth.

In fact, I could see both him and the wall at the same time, but I couldn’t see anything in front of me without tilting my head. I got dizzy looking through my wide spaced eyes, but I knew I only had one chance at the jump - Reamer wouldn’t give me distance for long - and I could already smell the sharp scent that I knew must be wafting out of my cunt.

I sprinted past Reamer, rounding about to face the five foot fence. Tilting my head to watch both the stallion and the fence at the same time, I kicked my hind legs off the muddy ground, and pounded forward. I felt confident in my feet - I could get the speed to clear the bar, but could I get the height?

Zack backed up, realizing now what I was doing. He gasped, "Ben, wait, no! You’ll never make it! Just stay there - I’ll find Madam Ruth and bring her here!”

The little fag had no idea what fate awaited me if I stayed here. I ran faster.

"You’ll get yourself killed!” the boy exclaimed, stepping out of the muddy pen through the gate.

Would that be so bad? I pictured it, leaping but not clearing the fence, my heavy body crashing into the metal posts. My legs would shatter for sure and maybe my back. Still, I don’t think Reamer would manage to fuck my dying corpse, so it wouldn’t be all bad. I was galloping now, and the fence would be there in just a few seconds. I tensed my legs to jump, bracing myself for the sickening impact...

My front hooves dug into the dirt, followed shortly by the back two. I balked, skidding as I turned to the side, smashing sideways into the fence. No, no, no, no! I was supposed to jump! That was my only chance! My ribs stung from the impact, but my legs were spared the brunt. Trembling, I turned to face Reamer, who grunted and flicked his tail. I swear I could tell that the horse was annoyed at my escape attempt, and I knew exactly how he’d get back at me for that!

I could try to build up speed and jump one of the other walls to the enclosure, but that would just put me in a pen with one of the other studs on the farm. Maybe if I kept my rump up against the fence until Zack got that scatter-brained witch bitch? I’d seen frightened mares try that before with no success, but I only needed to last ten minutes, and there weren’t any men leading me around with a rope. I faced the stallion, flattening my ears, and raising my thick, upper lip to show my menacing teeth. He just snorted, unafraid.

"You’re a girl!?” Zack cried, standing just behind me on the other side of the fence.

I jumped forward, suddenly realizing that with my ass pressed up against the fence, the perverted dog-fucker would have a perfect, unimpeded view of my newfound pussy. I couldn’t see it for myself, but I’d seen enough horse-cunt to know what it must look like - a pink, swollen teardrop, with a touch of deeper red peeking through the thick lips, squeezing closed only to open again to release another acrid puff of musk.

How long before he realizes the full extent of my plans for him? He was meant to be the horse, he was meant to be the filly, he was meant to service Reamer? Why wouldn’t he just go and get the witch!? I’d be sore-pressed to hold the massive stallion off even if the boy left right now, but at this rate, I didn’t expect him to remember he needed to get help until after Reamer was on my back!

The black thoroughbred didn’t waste any time! No sooner had I stepped away from the fence than Reamer had swooped in alongside me, curling his head around behind. I should have stayed back and ignored Zack, but it was too late now, with the stallion’s body pressing against mine. His neck muscles alone were enough to keep me from pushing him away.

Worse, he’d tucked his head below my tail for a reason. Before I could even whinny in protest, Reamer had nuzzled his way in, pressing his fleshy lips up against mine, and plunged his tongue inside me. I didn’t like it - how could I? - but I dropped my jaw and neighed, tail launching straight up. I was only a foot from the fence, Zack and Tinkerbell could see everything from the other side.

Every nerve trembled as I felt him sliiiiide his thick, wet tongue inside my cunt, warm breath washing over my thick, black pucker. Schlurp! rang out when he drew his tongue up, tugging and pulling my pussy lips, saliva slickening the dark pink tunnel. More than drool stained my hole though. Grunting, I tensed my cunt, gushing juices onto his tongue. Reamer pushed his jaw forward, up between my folds, teeth grating against me as he began to gulp, drinking it all up.

I knew I should just run forward and find another wall to hide in front of, and I sure as hell wasn’t a homo like the two dumbasses watching in silent shock, but I couldn’t move. I felt like my four hooves were rooted to the wet ground. The best I could do was lower my tail, the coarse hair flopping into Reamer’s eyes.

I should have known better. Reamer didn’t take kindly to resistance. Snorting loudly, he lowered his snout and clamped his flat teeth down onto my fat, white ass. It hurt! I hopped forward, letting out a sound that was half whinny, half whimper, looking over my shoulder at the big stallion.

I’d been trying not to look at him, but now I couldn’t look away. His huge, muscular body I knew well from years of watching him work, but never from this perspective. This time those dark, insistent eyes were on me, and the thick, pink and black cock swinging beneath his stomach was meant for me. I watched the thick organ sway, taking in all the veins and ridges. Reamer tossed his head and flagged his tail, and I lost control of my body.

Lifting my tail, I spread my legs and relaxed my body, only realizing too late what I was about to do. A cascade of yellow piss drained out of me into a puddle on the ground. I watched Reamer, frozen, as he lowered his snout to the growing pool, lifted his upper lip, and then whinnied into the chilly air. I flatted my ears, recognizing that sound. He was ready.

I might have stayed frozen there like a retard if Zack hadn’t brought me back to reality. He said, "Holy shit, Ben!”

I shook my head clear and jumped forward, but Reamer was bigger and faster. I only made it three steps before the black horse had not only caught up to me, but launched himself onto my back. I squealed as his enormous weight landed on my rump, making my hind legs buckle. I barely managed to keep my footing, though perhaps it would have been better to fall into the mud.

It was over, and I knew it. I was his, but I wasn’t about to go down easy. I bucked and kicked, neighing frantically in my effort to dislodge him. Reamer dug his sharp hooves into my hips, easily hanging on while I tired myself out. He could have just waited for a minute, but he was in a hurry. Pulling himself forward, he drew his strong, flat teeth to the back of my neck, clenching down around my white mane and sensitive neck. Tugging back, he forced my head up until I was squealing into the air, unable to move beneath him. That was all he needed from me.

I heard the faint slapping of his cock against his belly as he lifted it, humping forward every few seconds to test his aim. Reamer was an old hand by now - I braced myself, knowing that the blow would come, and come soon. At least I’d lost my virginity in Tinkerbell! I couldn’t have lived with myself if, like Derek, my first time had been as a whimpering bitch. Shivering, I spread my legs, biting my lip.

Sure enough, only now did Zack process what was going on. I watched with one eye over my shoulder as the boy stood transfixed by Reamer’s thick cock flapping up and down, getting closer and closer to my unprotected cunt. His eyes widened and he said, "I’ve got to get help!”

Too late for me, I knew. But it didn’t even get that far; before the boy took two steps, Slutpuppy reached over and grabbed Zack’s white pants awkwardly with her paws. He looked down at the dog and exclaimed, "Tinkerbell!?” as confused as ever. I thought maybe I’d lucked out, and the boy was just a complete moron, but then I heard the words that sealed my fate. "Oh my God…oh Jesus…” he shuddered as he dropped to his knees, and even from here, I could hear his voice breaking in relief over his next word: “…Derek…”

She nodded, letting go of his pant leg, before turning and looking straight at me with cold, dead eyes. The message was clear - she wanted to watch. Zack repeated, "Oh my God,” as the full realization took effect: I’d changed his brother into a horny cockslut, bred her to every dog in the neighborhood, and then fucked her myself, right in front of Zack. Bad enough, but then I’d enticed Zack to do it too. Now the boy knew. Now he realized what I meant to do to him with the potion. He gently removed the muzzle from around his former brother and stood next to her, both queers staring coldly as they waited to see me get reamed.

I only felt Reamer’s tip against my quivering pussy for a tenth of a second before it happened. Grunting, he tugged back with his teeth and launched himself forward, ramming straight into me like a freight train. My undersized cunt ripped open against his onslaught, and I thought my huge rump would tear in two! Arching my neck, I let loose a high-pitched, helpless squeal, legs buckling as more and more of his weight shifted forward, onto my back.

Behind, at their angle, the two siblings could see how much my pussy had to bulge to fit Reamer’s giant sausage. I swear, by the time his skidding came to a stop inside me, he was spreading me half a foot. My eyes shot open when I felt Reamer’s heavy balls smack against my butt, every inch of my tight, filly cunt trembling full. How could he possibly fit!? His fleshy tip poked and massaged the entrance to my womb, apparently exactly the right size to claim me completely.

Reamer let go with his teeth, whinnying loudly in my ear as he leaned forward, dug his front hooves into my thighs, and pulled back a foot or two. Just enough to slam forward again, forcing my slick hole to engulf him again. The force of his thrust picked my back legs all the way off the ground, wobbling when I finally landed back in the manure. I bugled pitifully into the air - it hurt, yes, but there was so much more. I wanted him. My pussy strained and squeezed around his giant dick. I even dug my front hooves into the mud and pushed back, rocking my hips up and down. Heat rushed to my face, but I didn’t care - I was nothing more than a cumbucket to the thoroughbred, a vagina at a convenient height, and for the moment, that was okay by me.

I even forgot about my audience, biting my lip and moaning into the crisp air. The only thing that existed was Reamer’s throbbing, pink-and-black cock pumping back and forth into my battered cunt. Ears flat and jaw dangling open, I squealed again, bucking beneath Reamer just to feel his swollen shaft shift inside me. I could hear and feel the thick, slimy pre-cum gushing out into my vagina, but that only made the pain dull, replaced by a slippery warmth. I’d watched Reamer at work dozens of times, but I’d always pictured myself as him, not as one of his whinnying conquests.

He bit down on my neck again, straining humps speeding up. I suddenly felt the pressure building inside of me, Reamer’s tail flagging as his cocktip flared, swelling up against my last line of defenses. My fertile womb was nestled up against the barrel of his gun, and I knew for a fact he wasn’t shooting blanks. Could I really get pregnant? Slutpuppy had fucked two dozen dogs at least, but it was too early to tell if any of them had taken. Reamer slammed forward, hilting himself inside of me so that his thick, black balls quivered against my teats. One thing was certain - if I could get knocked up, I was definitely going to.

Letting go of my neck one last time, Reamer tossed his head in the air and neighed, signaling his total domination of me. I joined him, my piercing whinny echoing throughout the empty stables. Flagging his tail, his hole pressed firmly against the tight opening to my egg chamber, Reamer let loose. A cannoning stream of thick, greasy cum shot straight into my womb, every quivering pulse of his balls signaling another sticky load. I dissolved into a whimpering bitch around him, just like Tinkerbell had for Pancakes and Beefstick, bucking and squeezing and moaning every second I was bred. My legs trembled at the glug, glug of Reamer’s blessed breeding staff trying to put out the fire in my uterus, heavy cream splattering my insides before settling wetly in the bottom of my belly. My eyes rolled back in my head, and I knew for a fact that this was it - I was coming away from this with a foal...or two!

Zack and Tinkerbell watched quietly as the next, grunting rush of cum backwashed out of my full cunt, spraying Reamer’s thighs. That was it, I was completely bulging and bloated with horse cum. Zack just stared murder into my eyes, shaking his head as if to say, "How could you?” He would never help me out of this situation now. I was going to be a filly forever - Reamer’s filly. I shivered, realizing I had better get used to being brimming with cum. Tinkerbell was still in heat almost a week after she should have cooled down; I would be in season as permanently as I would be a mare. And Reamer wasn’t the kind of stallion to leave a filly wanting.

I was still moaning, chest heaving for air, when Reamer finally backed off of me, slippery cum dragged out by his flared tip. Cum gushed down my hips like a waterfall, leaving no doubt as to what transpired. I kept my tail in the air, not wanting it to get stained and matted in cum. Sure, that meant that Zack and Tinkerbell could see every last drop bubbling out of me, but what did it matter? Covered in mud, shit, and cum, I had no dignity left.

Reamer just left me quivering there, walking over to his hay-trough to eat as if nothing had just happened. I’d been fucked by a horse, and if I couldn’t manage to jump out of here, it would happen again and again. The farm employees wouldn’t be back in full number until Monday. What would they do when they saw me in here? I could only hope that they transfer me somewhere else. Most likely they’d be puzzled, but wouldn’t look a gift filly in the cunt. They were in the business of breeding horses, and as far as I could tell, I was perfectly made for that!

How many times would I be panting underneath Reamer in the next two days? Turned out to be a moot question. I barely moved two feet before I heard a loud THWHUMP! All eyes turned to the newcomer, a draft horse who’d managed to jump the neighboring fence. I knew him, of course. I’d always called the shaggy brown stallion The Beast. Whinnying, I shied away from him, looking to Reamer. Stallions weren’t known to share, but the thoroughbred knew better than to pick a fight with The Beast. The draft horse was a foot taller than Reamer, and his cock was already as big and still swelling.

I was in for a long, hard weekend...

Chapter Text

And here I thought the most shocking day of my life would be the day I got drunk and fucked Ben Hendricks’ dog. I stood there at the stable, mouth on the floor, reeling from two rather startling revelations. I’d just watched Ben magically change shape into a horse – a female one at that! Perhaps more gut-wrenching was the realization that his dog, Tinkerbell, was my missing brother, Derek. Did I forget to mention that I had recently fucked ‘her’?

I turned down to the German Shepherd bitch, and every emotion I could ever feel hit me all at once. The tears were flowing freely before I could even fall to my knees, as I hugged my transformed brother with all my might. Tinkerbe…Derek…whined comfortingly in my ear as I sobbed against his rich fur. “Derek, I’m…...I’m so, so sorry…” And I had a whole hell of a lot to be remorseful; for shirking my chores onto him and losing him in the first place, for never figuring it out until now, for taking him for granted, for…

For rolling him onto his back and making love to him in front of his kidnapper.

She – he? – nuzzled firmly against my body and licked whatever was in reach, which only made me cry even harder. In the background, I heard a loud whump! that could only be that draft horse climbing onto Ben’s back, but this time we ignored him, as I was a bit preoccupied with my brother. “I missed you so much…” I sniffled and snorted into Derek’s shoulder and back. When I eventually composed myself, I pulled back and held his head in my hands, rubbing my thumbs under his eyes as if the dog could cry, too. “How can I fix you…what do I do?” I whispered hopelessly, trembling and staring into his mournful, admittedly beautiful milk chocolate eyes.

Derek cocked her head at me, obviously unable to answer. Then, her ears perked up and she darted into the horse pen. Avoiding the rampant clomps of the eight…well, six…hooves stomping around in ecstasy, my brother found the discarded, half empty bottle of the cursed liquid that started all this mess. She picked it up gingerly, careful not to spill or drink any as she brought it to me. I found the cork nearby and popped it in, once again reading the label on the side: “Love Potion #10 – Madame Ruth’s Magic Shop, 1135 Broadway Street. Do you think they’re open on Saturdays?”

Derek just shrugged, an odd expression on a dog. “Right, well, worth a shot.” I reached down and untied her leash from the fence and said, “Heel,” before I could stop myself.

When Derek whined, I said, sheepishly, “Shit…sorry, force of habit. But there are leash laws, you know.” I started to head for Broadway Street, trying to remember which train tracks led there the quickest. Derek set in beside me after one more look back. I glanced too, glaring as I watched the huge stallion ravage the little filly for the umpteenth time. We must have gone three blocks before I couldn’t hear her squealing anymore.

Sure enough, the magic shop was open, and I didn’t see a sign that said “No Dogs” so I just walked right in with Derek at my side. The store was filled with dusty trinkets, and I wondered why I’d never noticed it before. Evidently, they had real magic! You wouldn’t have known from the scratched, plastic counter and old, ragged cash register. I didn’t even see any signs about accepting credit cards.

Behind the counter was a woman with pointy-glasses like something out of a bad 80’s movie. Her hair was up in a bun, and she was hiding her chubbiness under a long, formless dress with flowers all over it. She had been reading a musty book, but looked up when the doorbell went off. I scratched my head and said, “Madam Ruth? We’ve got a... problem.”

She took one look at the German Shepherd at my side and said, “Not again.”

Again?

Confused, I followed her downstairs into a seedy looking basement where she knocked on an old, rotting door. Inside was a much older woman, in her sixties at least. I wondered why she would choose to look so old and wrinkled if she really could make magic potions! “Yes?” she asked, but when she saw me and Derek she took a deep breath.

“What happened.” The words sounded like a question, but she said it like a statement. “Don’t spare any details.”

I fumbled for words, finally just settling for showing her the bottle. Madam Ruth (if that’s who the old woman was) widened her eyes. “This is an experimental potion. Not for sale!” she peered down accusingly at me.

“I - I didn’t take it! Ben somehow got his hands on it!”

She looked sharply at the dog. “Bad dog,” she said gruffly.

“No, this isn’t Ben, this is my brother, Derek! Ben’s our neighbor.” This wasn’t going exactly as I expected.

“Why isn’t Ben with you?”

I looked down, stammering again. “He, uh…, he’s a bit preoccupied right now. You can save him, can’t you?”

“Save him?” she asked, arching an eyebrow. “He’s not even here!”

“Not Ben. Derek!”

Madam Ruth gave out a loud harrumph and stared at the younger woman. “Priscilla, how did this bottle leave the workshop? I swear I put a gigantic note on it, addressed to you.”

“I didn’t see anything,” Priscilla replied defensively. “This Ben must have stolen it.”

“While you were in the bathroom? Or just reading? Lord above!” the old woman said, throwing her hands up. She turned back to me and said, slowly, “This potion doesn’t wear off.”

My heart sank, and I couldn’t bring myself to look at Derek, who just whimpered. “Oh, I -”

“You didn’t let me finish!” she interrupted. “I have an antidote, and that’ll change your brother right quick.”

“Great!” I gasped, my heart starting to beat again in my chest.

“Quiet, boy! There’s a complication,” she said, taking a deep breath and removing her glasses to look me level in the eye. “It won’t work if she’s ‘with child’. I mean, puppies. Think carefully - is there any chance your brother may have mated? If she was ever alone, even for a few minutes…”

My face told the old woman everything she needed to know, while managing to leave out the details I was more than happy to conceal. I went beet red, knowing that that very first day I’d watched Beefstick breed my older brother first hand. I didn’t bother to mention that I’d been...personally involved in another mating of my brother, but at least that mating wouldn’t result in puppies.

“Ah. I suspected so,” she said sadly. “Then there’s nothing I can do.”

“What!?” I gasped, my stomach churning.

“For now!” she yelled. “Patience, boy – learn some! I’ll get you a vial, but you needn’t bother giving it to her until after the puppies are born. Be careful where you do it - she’ll change right back.”

And so I found myself sneaking back into Ben’s yard, with two little bottles in my pockets – the one that started this whole mess, and the one that would end it, eventually. Derek was quiet on the way home, but what could she say? Literally nothing.

I paused at the gate, my mind racing. What can I tell my parents? I know how worried they are, but they’d never believe me! Maybe I could forge a letter… “Derek, I’m so sorry,” I reiterated, scatterbrained. “If I’d known it was you I would have kicked Ben’s ass right away. I would never have gone to his house and -” gotten drunk and fucked you. I couldn’t say it. I slumped next to the tall, wooden fence with my head in my hands.

“Derek, what are we going to do?”

I was the younger brother. He was supposed to be the responsible one, he was the one who did the hard work when no one else would. Now she was the one who needed help and I didn’t feel ready at all. I looked at the German Shepherd, in her leash and collar. I wasn’t going to get any advice from Derek unless I asked it in the right way.

“You’re stuck like this until you, um, give birth in a month-and-a-half. Ben’s disappeared, right? I’ll tell the Hendricks that I’ll take care of you until he comes back.”

Derek shook her head. “Why not?” I asked, before groaning. I said, “Are you worried they’ll think I was involved?”

She nodded.

“I don’t care - the cops won’t find any proof. No one will think of asking the new filly where she came from. I’m not going to make you stay with them,” I said, pointing at the Hendrick house, “when you should be at home with us.”

Derek shook her head, patting the back of one paw with the other. I was confused until she went schlip, schlop (like a clock) with her tongue. “Now’s not the time?”

Nod.

“Okay, I guess you’re right. But I don’t care what you say, once they realize Ben’s missing, I’m going to offer to take care of you. Deal?”

Derek nodded, wagging her tail. I blushed, standing up, then realized that Derek could see my face and blushed harder. Dogs can’t see red, right? Hastily I said, “Well, what about after the puppies? Won’t they find it fishy when Tinkerbell disappears and you come home?”

I hadn’t asked a yes or no question, but her answer was clear. She just cocked her head and shrugged. “We’ll cross that bridge when we come to it, yeah. Are you ready to go in?” I asked, not ready at all, myself. I wasn’t going to be getting much sleep tonight, thinking about my brother being trapped in the house next door, going on walks to pee and eating kibble and cold dog food. I turned my head in the cardinal direction of that farm so far away, and took some cold comfort in replaying his panicked terror in my mind. Ben deserves what he got, I thought.

Slowly, I said as much. Madam Ruth had made me promise to free Ben as well, but I told Derek, “There’s enough antidote for Ben, but I’m not going to give it to that piece of shit…Not after what she did to you.”

Derek looked down, her tail still. I could tell she was conflicted. Just like my brother to turn the other cheek, even now. I knelt down again and rubbed behind her ears. “There’s still plenty of time to decide. If those huge balls were any indication, she’s pretty well knocked up. So that gives us – what – ten months? You do realize he meant for me to be the filly, and I doubt Ben was going to fix either of us.”

Derek nodded, but she didn’t look up. I sighed tiredly. “We’ll talk about it later,” I said, getting up. I peeked over the fence, but no one was inside. I just had to drop ‘Tinkerbell’ off and pretend I never saw Ben today. There was definitely going to be a hubbub when a second boy simply vanished from the same neighborhood. We walked through the gate, and I undid the leash. Walking to the gate to my backyard, I said, “Well...I’ll see you around?” weakly.

*

Pancakes and Beefstick were out, and when they saw me they began to bark their heads off. It was only about 11:00 in the morning, and I could see that both households were basically empty. Their cars were missing in the driveways. That’s right, Mom had an appointment at the salon, and Dad was meeting a colleague for golf. I had no idea where the Hendricks were, but if anyone was home, it was probably just Sarah sleeping in. But why were the dogs out?

I must not have latched the door when I rushed outside to meet Ben. Sure enough, the back door was open just a touch. Well, at least they hadn’t gotten into the trash! I put my hand on the gate, getting ready to leave my brother to her yard when she suddenly rushed over and grabbed my pant leg in her teeth. “Huh?” I asked.

She wedged her way in front of me, scratching at the gate to our backyard, whining. “I thought you wanted to stay with the Hendricks?”

She nodded, but then shook her head. Now I was really confused. While she pawed at the gate, I said, “I don’t get it. Besides, the dogs are out and -”

Yip! she said, wagging her tail.

Oh.

Ohhhh.

“You want to go in with them?” I asked, and this time she gave me a vigorous nod. My face went red, and despite the chill, I started sweating. Could she really be suggesting what I thought she was suggesting? “But you’re still in heat – they’ll…”

Derek just barked and whined, scratching at the gate.

I didn’t know what to do or say. My brother wanted to get fucked by the dogs! I mean, sure, I wanted to spend some quality time with Alexis Green, too, but I didn’t tell that to Derek. Has she no shame? I had to convince her otherwise, and I knew just the thing. I said, “You know I’ll have to supervise to make sure they don’t hurt you.”

Derek scratched at the gate even harder. Good Lord! I dropped my jaw. How good was the sex, how much did her heat have to affect her for her to just shrug at the thought that her twelve-year-old brother was going to watch her getting fucked? My plan had royally backfired, and I couldn’t say no, now. Then again, I had fucked her, myself. If this was really what Derek wanted…

I could feel my cock getting hard, so I fumbled at the gate, opening it. Derek darted inside, and I followed, closing the door behind me. I realized then that Pancakes and Beefstick hadn’t been barking at me. They didn’t give me a second glance. They could smell ‘Tinkerbell’. Jumping and darting around, the studs circled around my brother, tails wagging furiously.

“Hey now!” I shouted. “Gentle, gentle…”

We weren’t supposed to have both dogs out with a bitch in heat at the same time, but Derek didn’t seem to mind, so I just watched from a safe distance, ready to step in if things got aggressive. Things calmed down greatly when the males found what they were looking for. Together, they shoved their noses into Derek’s rump, and she whimpered, spreading her legs and lifting her tail.

As they sniffed and licked, I began to realize that this was really happening. Unless I stepped in, I was about to watch my own brother getting fucked in her pussy by the family dogs. Sure, I’d seen Beefstick have a go with her before, but I didn’t know it was Derek. Now, with her slender rump bouncing up and down against their tongues slobbering against each other, it was clear how much she wanted this. My pants were tented now, and I couldn’t help but think back to when ‘Slutpuppy’ was laying on her back for me - when I’d lost my virginity in my own, whimpering brother.

Man, do I need some counseling.

Pancakes was the first again, shoving the larger, darker shepherd away to jump onto Derek’s back. This time, however, Beefstick wasn’t willing to wait his turn. Snarling, the large dog leapt at Pancakes and snapped at him, though he let his jaws snap closed an inch shy. “Hey, hey!” I said, stepping in. “Bad dog!” Beefstick looked up at me and whimpered, and I corralled him away from the other two. “Let them do their thing,” I commanded, turning back.

Derek was looking over her shoulder at Pancakes, who scootched forward onto her back, his cock-tip already poking out of his chubby sheath. He wasn’t much for foreplay! She just whined, her tongue lolling out the side of her mouth. From the side as I was, I could watch as that glistening tip shoved closer and closer until it was brushing up against my brother’s quivering mound.

I’d watched dozens of matings before, but never like this. This time, Pancakes was slowly wedging my brother apart. I watched the stud hump and grunt, finding his mark with a practiced motion, sinking inside of Derek as she whimpered. I’d never cared too much about it before, but now I couldn’t tear my eyes away. Derek wasn’t looking my way, so groaning, I slid my hand to my crotch, rubbing the bulge that was growing there.

Yip! Derek spread her legs and bucked her hips, tail wagging awkwardly against Pancakes’ hips. He hammered just as hard, driving more and more of his curved, bulging cock into her tight pussy. I knew firsthand how big the dogs were - two, three times as big as me, especially if you counted the knots. I could just picture his huge length ploughing deep into my brother, making her hump and whine.

Beefstick watched patiently now, his tongue dangling and his cock sticking lewdly out. How my own cock wanted to be let out, but what if Derek looked my way? Instead, I just rubbed it through my baggy jeans, picturing myself on my brother’s back. It’s not gay if he’s a she, is it?

Pancaked was hammering flush with her hips now, swelling inside of her. Soon her pussy would be stretched and distended, clenching the full, throbbing cock inside her. A sharp slap! slap! slap! rang out as his heavy balls swung against her again and again, a promise of what was to come. We both knew she was already full of Pancakes’ puppy batter, but the dog didn’t know. As far as he was concerned, he was about to let loose a fresh litter inside his quivering bitch.

I knew I should just wait and watch, but I couldn’t. I lied to myself and said I had to do what I’d seen my father do a dozen times before - I had to make sure that Pancakes was properly knotting. Our clients wanted to know how many ties were completed, and sometimes Dad needed to help with a particularly squeamish bitch. Heart racing, I crawled up beside the breeding dogs, placing one hand on my brother’s rump, and one on Pancakes’ thigh to push the fur back and look.

Derek didn’t seem to mind.

Now I could see everything up close, the way his thick, black balls smacked Derek’s underbelly, the rapid, eager thrusts that drove more and more of his cock inside. Sure enough, he hadn’t tied yet, his knot still swelling just outside my brother’s cunt. “C’mon boy! Harder!” I whispered encouragingly, as I’d heard my father say. “Get that thing inside her!”

He pounded harder, the growing bulge smacking up against her like a lusty kiss. Her heat-swollen spade stretched and yawned around him, wedged further and further open until I got a perfect view of the pop! Pancakes’ sunk himself into his bitch, making my brother’s pussy bulge like a baseball.

And he was still growing, sealing himself inside. I watched her mount inflate like a balloon until her vulva was quivering about the size of a softball. She wasn’t going anywhere until he was done with her now. “Good boy!” I said.

It all happened so fast. Pancakes lunged forward so hard my hands lost their grip and I fell backwards onto my ass. Even I could hear the loud splurt! as his balls began to pulse dumping a warm, sticky load deep in Derek’s pussy. She arched her head back and howled, humping and bucking so hard I worried she might hurt the poor boy! With her eyes rolled back in her head and her tongue dangling and drooling on the ground beneath her, I knew why her sex drive had overtaken her humiliation. She whined in ecstasy, clenching and milking every last drop from our dog’s twitching cock.

All I could do was watch and rub my crotch, knowing that Derek wasn’t going to see anything but stars for the next few minutes.

Pancakes was done with her rump. He had what he needed, so he spun around, panting and squirting through the tie. Their tails wagged together, Derek still whining and humping. I looked beneath their tails at the huge bulge that looked painful, if not impossible. What had once been a pointed, y-shaped mound was now a swollen grapefruit, her delicate entrance stretched out and quivering around the thing base of Pancakes’ cock. Despite the knot, I watched as white fluids dribbled out and landed on the grass below.

Derek was shuddering around him, bucking her hips and tugging back. Pancakes whined at the extra pressure where their genitals strained against each other, so I had to interject firmly: “Derek, stop. Be gentle - you know you have to wait.”

For a few desperate moments, I knew that I was going to be next. Beefstick would have to wait his turn as I covered my brother, lowering my pants and sliding my cock to her sopping, quivering cunt. Derek wouldn’t say no – he couldn’t!

I might have done it, too, if not for the ten minutes of waiting. By the time Pancakes pulled free, the violent urges inside of me had calmed down. I lifted each dogs’ tail, inspecting them for damage, but found none, just a cum-drizzled pussy and throbbing, dangling cock. “Good boy!” I praised him again. Pancakes had been pretty clumsy starting out, missing a lot and being too rough, but he’d become a real gentleman.

Derek glanced back at me and whimpered. I blushed, letting go of her tail. Not meeting her gaze, I asked, “Is that good enough, or do you want Beefstick?”

She answered me by walking bow-legged over to the dark-furred dog, leaving a wet trail behind her. I took a deep breath, trying to remain calm as I watched our second dog get up and start lapping at my brother’s well-used pussy. She held her tail rigidly aside and waited, trembling, for the inevitable.

While I watched and Pancakes patiently lapped at his messy cock, Beefstick clambered on top of Derek. Wasting no time, the large, eager shepherd launched himself hilt-deep in one practiced thrust, spreading her wide with a wet splorch! Barely a minute had passed since she’d tugged free from Pancakes, and without missing a beat, my brother was rocking and moaning beneath another stud!

This time I had a nice, private back door view. I watched beneath Beef’s raised tail, his enormous balls swinging back and forth which each powerful thrust. I couldn’t make out much more than Derek’s achingly spread hind legs, but that was enough. She couldn’t see me, and no one else was around, so I slipped my hand beneath my pants and grabbed my cock. I was surprised to find my underpants so wet, but I didn’t let that stop me. Sitting on my ass, and I cupped my cock and humped my hips, masturbating to my brother getting fucked by my dog.

Hump! hump! hump! went Beefstick’s hips, ploughing his eager bitch. His cock was much wider, spreading her until her lips were aching, but I knew Derek didn’t mind. She let out squeal after high-pitched squeal, tail wagging. I saw her dig her nails into the dirt and push back, grinding her tight pussy against his growing knot.

I couldn’t help it - I came. It was all too much for me. I shot into my underpants, quivering and gasping, trying to stay quiet. When I opened my eyes, I saw Derek looking back over her shoulder. My heart stopped, and I slid my hand out from my jeans, but I don’t think she saw me. She was curled up, trying to watch the huge cock that was reaming her apart. I only beat them to the punch by a minute, soon, the two dogs were slamming against each other, cum rushing into her pregnant belly.

She was completely out of breath, collapsing on the ground so that her rump dangled in the air. Beefstick didn’t mind, rump-to-rump and panting as he continued to seed his bitch. We’d never be able to tell which of the puppies were his and which were Pancakes’, but we couldn’t really get papers for them anyway. ‘Tinkerbell’s’ sire and dam were most certainly not purebred German Shepherds! I checked the knot, and everything was fine. This time, when her mate pulled out, Derek was done. Panting and waddling, she scratched at the gate, and I let her out – to her home for the next month or two.

Scratching my head, I said, “Uh...if you need anything, you know...just let me know, okay?”

Derek just barked.

* * * * *

Life with Sarah wasn’t so bad. I didn’t get to see Zack except in glimpses when I was walked, but that didn’t matter to me. I was just happy to spend my time with her. Honestly, I couldn’t believe that Sarah and Ben were even siblings. It’s like all the evil genes went to Ben, and all the good, to Sarah.

A lot happened in the next few days, and Sarah needed a lot of cuddles from her favorite Tinkerbell. No one found a trace of Ben, the second disappearance of a fourteen-year-old boy in a week… The police questioned everyone, but there was no evidence of any wrongdoing - they just figured he’d run away from home. They had no idea he was getting plowed a dozen times daily just a few minutes away. And with that ‘special connection’ we shared, it wasn’t long until those tearful comforting cuddles in the darkened bedroom eventually turned to soft wet lapping and hushed moans.

My pregnancy was advancing quickly, and soon enough, my eight teats started to get heavy with milk and I could only move slowly around the house. I knew that my long nightmare would soon be over, but I still couldn’t help but hope my puppies came out happy and healthy. I could feel them kicking around inside my belly.

When the day finally came, Sarah laid out a beautiful, plush whelping box. I could feel them coming, but it still took hours. I curled up in the box, whimpering as I waited and waited. Because Zack had been asking after me for weeks, they called him over when the time came, so Sarah, Zack, and Sarah’s parents were all clustered around me when the first pup came.

Groaning, I found it surprisingly easy to clench my legs together and push. Slowly, slowly, the blind, wet, defenseless little puppy emerged from my straining vulva, almost three months since I’d first turned into ‘Tinkerbell’ and been mounted by Pancakes and Beefstick. I couldn’t know which was the father of which puppy, but I did know one thing.

This adorable little puppy dog was part of me. As a fourteen-year-old boy, I’d never really thought about that sensation, but now I was tingling with it. I was giving birth to new life, a little creature comprised of both me and its father. Half of my essence had flowed into this extension of me, and there were more coming. Carefully, I chewed through the umbilical cord, almost sad to lose that most intimate connection with my baby.

While I was still licking the first one clean to cheers from my audience, the second started to come. Biting my lip, I grunted and pushed. The first pup’s brother came, yipping softly in short barks that sounded like a sea lion, moving its little paws aimlessly as it was born into the world. The two boys curled up next to each other as I nipped the cord and continued to clean them up.

I could tell that I was making Zack nervous. The twelve-year-old was the only one who knew I was really human, so every time I licked the blood off of one of my puppies, he grimaced.

I was done cleaning both, and my audience was talking about the state fair when, twenty minutes after the second pup, I felt the urge again. Squeezing and panting, my first beautiful little girl pushed into the world. While I lifted my head to clean her, the other two pups finally realized that I existed, and crawled pitifully over to my stomach.

Lifting a paw, I offered them my belly and they quickly each found a swollen, turgid teat. I couldn’t help but yip! as their sharp teeth dug into my nipples, but I enjoyed the release of pressure that had been building up for weeks. Warm milk dribbled down their throats, and I realized just how much these little guys needed me. From the get go, I’d given them half of everything inside me, and then I’d fostered them as they grew, these simple little cords feeding them energy and nutrients. Now, all three drank deep from the fatty milk I provided them.

Oof.

The fourth pup was coming.

After that, and the fifth, I looked down at my beautiful litter, two males and three females whimpering and demanding milk. While Sarah’s parents poured everyone hot chocolate, Zack crawled slowly next to me, as close as he dared, and whispered, “I’ve got the antidote.”

I shook my head. If I drank it now, I might change back immediately.

…But that wasn’t why I said ‘no’.

Zack nodded, “I’ll give it to you tonight, when they go to bed.”

I shook my head, making sure that the Hendricks weren’t watching.

“Tomorrow?” Zack seemed confused until he followed my gaze down at the five puppies nursing contentedly.

Zack said, “How many weeks? One?” realizing that I wouldn’t abandon my puppies, even though it meant being stuck as a dog for that much longer.

I shook my head again and again as he counted up. “Two? Three? Four?”

Zack paused and shuddered. “You’re not changing back?” he said with sudden realization.

My eyes bugged out, and I growled at him, hackles raised. What!? I liked my puppies, sure, but I was not going to be a dog for the rest of my life!

“Oh, sorry. Five? Six? Seven? Eight?” he continued, until I finally nodded at eight weeks. Sarah had been looking up how to raise puppies and weaning ended about then. As much as I loved these strange little bundles more than I ever expected, I wanted to get back to my life.

“Jesus, Derek,” my brother said, shaking his head.

Sarah finally noticed him crouching beside the proud mama. “How’s she doing?”

Zack was startled but recovered quickly. “Not bad.”

After Zack went home, a half hour later I had my sixth and final pup, another little girl. While the others were clearly German Shepherds, this one looked like a mix, and she was noticeably bigger than the others. Looks like Samson got one past the goalie after all! I had to nose her over to my teats, which were already practically empty thanks to her older siblings, but I made sure each furball got a fair shot.

Raising pups wasn’t hard, but it was exhausting, and I had to eat a lot to keep up with the milk I was producing. After the pups’ eyes opened and Sarah got a better sense of their personalities, they got their names. One male was named Beefcake, in honor of their fathers), and if I could have had my own input I would have - she named the second male “Benji” after her brother.

How could I tell her that Ben had been the cause of all this, and no pup deserved to be named after that horrible monster? I took to calling him Jamin in my head. Sarah named the four girls Flopsy, Blueberries, Cream, and, believe it or not, she named the Dane-mix Derika. She named one of the bitches after me, and the males after Ben.

Finally, the pups were completely weaned and ready to find their new homes. As much as I wanted to be human again, I would miss my life as Sarah’s pet dog…for more than one reason. I shared her bed every night, and most of those nights, well….the eighteen-year-old (her birthday was three weeks ago) learned quickly that I didn’t need peanut butter at all; I slaked my thirst with a vengeance whenever she spread her legs for me. She blushed every time, and afterward, she’d always pant out exhaustedly “That’s the last time,” but after I teasingly licked up all the sweat from her pubic bone, navel, nipples and neck, by the time I made it to her lips, we’d have another ‘last time’ one right after the other. And Sarah, unlike Ben, wasn’t a selfish prick. She always returned the favor, usually with her tongue.

I gave Zack the nod next time I saw him that the time had come, and he promised to come by late that night with the antidote. I was hardly able to walk for excitement. I would be myself again! I could play video games, go to school (never in my life did I think I’d be excited for that), and flirt awkwardly with girls again! I knew I wouldn’t fare well with the ladies, and my stint as a bitch didn’t help with that. Flirting with dogs was a piece of cake - you just lift your tail.

Or sometimes, not even that. Just my luck, Isaac was walking Samson that very day, and Sarah and the football player started talking. What was Sarah thinking!? She knew as well as I did that I’d never really gone out of heat, though she couldn’t find a reason why on the internet. Sarah had been so careful, even when walking me a few days after giving birth, well aware that I might already be fertile again.

Now, though, the picturesque Isaac had drawn her attention once more, leaving me to crouch and cower before the mighty Great Dane once again. The huge, Harlequin Dane noticed my scent immediately. He wasn’t about to take ‘no thanks’ for an answer, either. Before I could even yip, the massive animal stuffed his snout beneath my tail.

I was about to protest when his huge tongue lapped against my swollen spade. Instead, I dropped my jaw, eyes bugging out. It felt so good! I hadn’t been fucked since the day Ben ‘disappeared’, and Sarah’s fingers and tongue just couldn’t match the dog’s wet organ, and certainly couldn’t match his huge, glistening cock.

Slowly, I raised my rump for Derika’s father, shivering as the horny dog slurped my engorged pussy. I wondered if he remembered me - he was certainly forward enough. Isaac and Sarah were locked in each other’s eyes, having completely forgotten that this exact problem had happened five months ago.

After every lick, I opened my mouth to bark, but no sound came out. I pushed back, my floppy teats swinging back and forth. Did Samson realize he was partially responsible for those distended mammaries?

What am I doing!? I wondered, realizing that if Samson climbed on my back, it would already be too late. The teenagers hadn’t been able to pull him off last time, and they wouldn’t this time either. Samson would wrap his huge paws around my hips and give it to me, whether I wanted it or not.

And God, did I want it. I was desperate for him to climb on up, hump forward, and tie with me, pumping load after load into my fertile womb. My bloated spade was trembling beneath his tongue, spreading apart so that more and more of his fervent licks went deeper and deeper. Every fiber of my being cried out for the Great Dane.

Groaning in excitement, I felt a paw on my rump, and I knew it was too late. He was going to take me again, his fat, throbbing cock oozing me full of little mutts, and I’d just wasted my only opportunity to stop him. With an eager sigh, I spread my legs and buckled my knees, my eyes clenched shut.

“Bad dog!” Isaac yelped, yanking on the leash.

The oversized paw in question was ripped away from my rump before it could wrap around me, and Samson barked, but was held away as Sarah jumped back, in shock. “Holy crap,” she gasped. “It almost happened again!”

Isaac blushed, looking over at her. “I saw on Facebook that one of the puppies took. Since, you know, he’s the father, I wondered if I could have that one?”

“Her name’s Derika, and well...I guess so. They all need homes after all. My parents won’t let me keep more than one dog.”

Isaac says, “Wow, cool! I can’t wait.”

Meanwhile, I stood there, trembling for two reasons. I’d almost given in and risked getting knocked up again on the very day I was supposed to change back, and also because my entire canine body was shaking with desire for the big, muscular stud dog just feet away. My sopping pussy was leaking both his saliva and my own arousal, more than enough to prepare me for him (since I’d had less last time).

“Look at her,” Sarah said. “She wants it.”

“Uh?” Isaac said, surprised at the wording. Looking down, he realized Sarah didn’t mean that I wanted to keep Derika. “Oh. Yeah, she’s trembling…”

Sarah said, “You know, she just weaned puppies. The internet says she won’t be in heat for another three to six months.”

Isaac shrugs, “Yeah?” not sure where this is going.

“If she really wants it, why not let them? No harm, no foul, right?”

Yes, harm! I whined. ‘The internet’ didn’t know that I was magically transformed to be the perfect mate for Pancakes! Now, I didn’t know for sure that my permanent heat just meant I was always horny, or if, now that my womb was empty, it meant that I was overdue for another litter, but now was certainly not the time to be taking that risk!

“Right here on the street!?” Isaac gasped, blushing and looking around.

“No, we’re still close to my house. We could use my backyard. Lord knows the neighbors breed theirs often enough they can hardly complain.”

“A-alright,” Isaac agreed, and they walked the two of home, a gentle drip, drop, plip, plop trailing behind me.

How am I going to get out of this!?

I still hadn’t thought of a way when they opened the back door and led the two of us into the backyard. I noticed that the puppies were done exercising and were sleeping outside in a big pile on a nearby dog bed. Sarah’s parents weren’t home, so they weren’t going to stop her. Desperately, I looked over to my yard to see if Zack was around, but he wasn’t, either.

Quivering, I looked up at Samson, the eager dog already half-hard and ready to mount. This is really going to happen, I realized.

Isaac could barely restrain the huge Dane, while Sarah leaned down to remove my leash. She whispered in my ear, “You want it, don’t you? Then go ahead!”

Sarah was beaming at me as I stepped forward, free from restraints. Oh, I could run for it, but Samson would catch me. Maybe they could pull him away from me in time, but probably not. Shivering, I realized that Sarah was right. I did want this. Whimpering, I turned away from Samson, raised my tail, and barked at him.

Isaac was about to let go of the leash - just as Zack walked into the back yard, glancing over at the scene over the fence. His eyes widened and he shouted, “Wait! Stop!”

Amazingly, Isaac managed to grab the leash again, even as it started to fly from his hands, the Great Dane tugging powerfully at his lead. Digging his feet in, he counterbalanced the hundred-and-fifty-pound behemoth. Sarah and Isaac turned to the twelve-year-old, who had far more experience breeding dogs than they did.

“She’s not ready to be bred,” Zack gasped, rushing over to the fence.

Sarah tried to defend herself. “Well, she was...flirting with Samson a lot…”

Zack blinked. “She was?”

My brother stared down at me, knowing how true that might be. I blushed, but thankfully no one could see. Zack said, “Hold Samson still. Let’s see what she does.”

He was letting me choose? He knew what could happen...the risk I would be taking. Again, I had to consider what I really wanted. He might not even knock me up, and I’d be back to my old self in no time, but even if he did, it would just be another five or six months living with Sarah. Another six months before her beloved dog disappeared forever with no explanation. Those were good things!

Whining, I took a step backward, waggling my raised rump at the Great Dane.

Isaac said, “There’s your answer.”

Zack’s jaw dropped. “But…”

Isaac let go of the leash, and this time, Samson wasted no time. The huge dog barreled toward me, leaping onto my back. Yelp! I winced, as my legs buckled under his enormous weight. He snorted, his warm breath blanketing the back of my head as the first large droplets of drool splattered my neck.

Why did I do that? Zack gave me the perfect opportunity to escape. Now I’m going to get stuffed right in front of the girl I like, her stupid-ass boyfriend, and my own brother - not to mention my own puppies! But when I felt Samson’s huge, bony tip prodding up against my bouncing vulva, I knew exactly why. None of that mattered when the time came. All that mattered was the sheer, intense bliss of mating. I would suffer for half-a-year for one minute of sex with Samson.

Zack had hesitated, but now he yelled and opened the fence between our yards. “No, stop him! It’s not safe to breed her again so soon - she could get hurt!”

Sarah and Isaac exchanged glances, not having thought of that, but they stood, frozen and helpless as the Great Dane lowered his hips, angling his first thrust for my heat-swollen spade.

Zack ran to intervene, even though I was barking at him to stop, to leave me be, to let Samson have me. He ignored me, sliding to the grass beside us, reaching forward to push Samson’s cock out of the way.

He was too late.

Samson growled and thrust, slamming himself deep into my suddenly overstuffed cunt until my eyes were so wide, I could see stars. Thank God I’d given birth - the pain from last time was a gentle ache now as I squeezed down around his fat Dane cock.

“Help me get him off her!” Zack cried, but again, Isaac and Sarah did nothing.

Except Isaac said, “We tried that last time - there’s no way he’ll let her go.”

Zack threw his hands up, frustrated, nowhere near strong enough to dislodge a horny Great Dane. The spotted dog hammered deeper and deeper until he was hilted inside me, his tip grinding up against my waiting womb. My tongue spilled out the side of my mouth, and I, too, was drooling as he had his way with me. This time, he’d claim all my puppies, a litter of 6 chubby little Great Dane mixes. I would absolutely be rolling around to get anywhere when my belly swelled.

“Dammit,” Zack gasped. “He’s going to knot her!”

Sarah took a step forward and stood up for me. “Zack, back off. She’s obviously enjoying it and she’s not your dog.”

Zack glowered at her, never mind her five years seniority. He said, “That’s not the point - he could hurt her.”

Oh, but it hurt...it hurt so good. Every violent thrust reamed my tiny body, lifting me off the ground as he pulled back and pushed in, sliding through every inch of my tight, quivering passage. He was so wide, I was literally bulging beneath him, but the small discomfort was worth it. Samson leaned forward, keeping himself buried deep as his knot began to swell, his half-thrusts still sending his heavy balls into my rump.

Zack kneeled next to me and whispered in my ear, “What the fuck! You want to go through this again!?”

I glanced at him and whimpered, but all I did was buck backward, grinding my hindquarters against him in tight circles. Zack finally sighed and gave up, crossing his arms as he watched his older brother. I wonder if he felt like I was choosing Sarah over him - he knew where I would be staying for the next six months.

Isaac said, “Wow, he’s really going at her.”

Vaguely, I noticed a few of my puppies had woken up and were watching nervously, too afraid to approach the huge dog that had their mother in his grasp. Derika didn’t seem to recognize the dog as her father. Benji was the only pup with the courage to get a little closer.

I didn’t care. About any of it. Right now, even Zack’s obvious disappointment was just a buzz in the back of my mind. The only thing that mattered was Samson. Not even that - the only thing that mattered was Samson’s cock, pounding me mercilessly as his knot began to swell. How long it had been since I’d last had a dog knot in me! I spread my legs apart and pushed back, engulfing him completely as he grew tight inside me. My swollen teats swung back and forth beneath me and my vulva bulged out like a softball around the Dane’s enormous equipment, and there was no coming back from that.

With a loud bellow, Samson let loose, humping up and in so hard that I swore he had pushed his pointed tip straight through my cervix. I could feel his huge balls clench against my thighs as the first loud, wet gush of cum shot straight into my fertile womb. I’d been looking for excuses when I thought maybe I was in heat, but not fertile. Pancakes had wanted pups, and he’d gotten them. I was more than ready to meet the thick, bubbling flood of sperm with quivering, defenseless eggs.

I dropped my jaw and howled, shuddering in every direction as I came, my pussy vibrating like one of Sarah’s toys against Samson’s thick bulge. Pleasure coursed in waves throughout my body, and I knelt down to allow gravity to help draw his greasy cum into my depths. There was no doubt in my mind that I was his bitch now, and soon the dam to his litter. It’s not so bad…

While Samson ensured a nice, fat belly of pups, Sarah and Isaac held hands, and Zack glowered at them. I could only look at him as apologetically as a dog could, with a little shrug - what could I do? Samson!

The huge, swollen gland held everything inside, leaving my belly heavy and sloshing with cum. With a loud grunt, Samson turned around, still squeezing out load after load while I quivered beneath him. I came again, and again, just from the sheer girth inside me, and the sure knowledge that I’d just given this eager dog the next six months of my life. I could only guess what I would do once the puppies were weaned if I saw Samson again.

No, I didn’t have to guess. I knew exactly what I’d do: lift my tail.

Finally, he was done, and we stood there panting for almost ten minutes before Samson pulled free without a parting glance at me. He returned, tail-wagging to Isaac, leaving me in a pool of cum on the ground.

Zack tried to come to me, but Sarah was faster, saying, “Good girl...you liked that, didn’t you? Well...we can do it again tomorrow, if you like.”

My eyes lit up and I barked at her. Sarah was always looking out for me.

Zack rolled his eyes and got up. “Another batch of mutts,” he said dismissively. Suddenly, I wanted to bite him!

Isaac stopped petting Samson and said, “Huh? Oh, no, that won’t happen. After last time, we got Samson a vasectomy…”

Zack paused. “What!? Why didn’t you say something!?”

He’s...been fixed?

Isaac shrugged, and Sarah said, “You said you were worried about Tinkerbell.”

Zack said, “Not anymore.”

The next morning, when I was walking outside, Zack ushered me over to the fence. I wasn’t sure I should talk to him. Sarah had promised me another breeding with Samson.

“Derek,” he said quietly. “I’ve got the antidote right here. You can take it and we can go ahead with our plan that Tinkerbell ran off, and you were out ‘finding yourself’. Or...you can stay here forever.”

I shook my head. Not forever. I just wanted to enjoy Samson a few more times.

Zack shook his head. “You’re letting the magic get to you, Derek. Every day you stay here, you get used to your new life. You’ll never want to come back. You’ll stay a dog forever, making puppies…”

That doesn’t sound so bad… I looked up at him, cocking my head.

Zack rolled his eyes, explaining. “I can tell how much you like Sarah. You’ve already stayed with her for half a year. You won’t want to leave because it will devastate her. Better to leave her now, before she becomes too attached.”

Zack paused, and added, “Or never leave at all.” He held out two hands, one that was empty, and one with the bottle of antidote.

He was right. I had to choose, and as much as I liked my life as a dog, and knew that I’d live a happy ten years with Sarah, she was going to college soon, and had her own life. And she was spending way too much time with Isaac, anyway. I had to return to my old life, even though it was decidedly less satisfying. Meet girls, learn facts, get a job...then maybe I could spend time with Sarah as equals, not as her pet.

It hurt, but slowly, I nosed the antidote.

* * * * *

I couldn’t wipe the tears away from my eyes enough. Tinkerbell was gone. Someone had left the front gate open, and she was gone. At first, I expected to see her show up, tail wagging at the door, but as the days turned to weeks, I knew that wasn’t going to happen. I could only hope that wherever she was, she was happy…

I swiveled my chair and slid to my desk. Isaac emailed me again to go out. At least that was going well. We were talking college plans, and SoCal was looking like a good option. Idly, I reached down to pat Benji’s head. My parents would never try to give him away, not once Tinkerbell disappeared. I’d been hoping to take Tinkerbell to college, finding some housing for dogs somewhere, but Benji would do. He was cute, and he liked peanut butter. I wondered if his ears would ever stand straight up.

As I reached for my makeup, I noticed the corner of Ben’s phone sitting in the corner. I’d hidden it from the police when they searched through his room. We still had no idea where he was, or if he was even alive. At first, I’d thought he’d run away to find Derek, but Derek had come back. Said he’d had to ‘find himself’, and I guess he had. He seemed so much older than before, so much calmer and more composed.

But Ben never came back. Just like Tinkerbell.

Maybe it’s for the best. I don’t know what I’d say to him about the video I found on his phone. I couldn’t let the police see it, and I couldn’t let my parents know. I’d suspected he was abusing Tinkerbell, but I never would have guessed exactly what had been going on.

Poor Tinkerbell.
