Third person POV

Grayson has been anticipating this day for many months now. He is finally going to meet his girlfriend’s family for the first time. He made sure to wear something proper and formal, but nothing too formal so it wont look like he’s trying too hard. He wore a simple black shirt to give off a clean appearance, along with black pants, a pair of Nike shoes, and finalizing his outfit by adding a touch of flair with a stylish new wristwatch.

When he arrived at his girlfriend’s house, he succeed to make a first good impression to her mom and dad. Grayson would’ve gotten an A+ from his girlfriend’s entire family if it wasn’t for… her little brother, Finn.

Finn did not approve of his big sister’s choice of boyfriend. Or at least, that’s what Grayson thinks.

From the second he saw Grayson entering the house, Finn has been curled up in corner of the couch with his timid little head facing down.

Grayson carefully sits on the same couch as Finn, and try’s talking to him for a good several minutes now. Grayson makes sure that his voice is soft and gentle when talking to Finn. But not a single word would comes out of Finn’s shy little mouth.

He attempts to get Finn to come out of his shell by gifting him a shiny new toy car for him to play with. But it was no use. Finn shyly took the toy car from Grayson’s hands, but he didn’t play with it, nor did he even make eye contact with him. Finn’s rosy cheeks were getting gradually brighter the more Grayson would try to talk to him. But he still wouldn’t budge.

Grayson didn’t give up though. Eventually, Finn finally cracked a smile when Grayson told him a goofy joke which got Finn giggling like crazy. It was hard for Finn to contain his giggles. Grayson was thrilled to have gotten Finn to laugh a little. But when Grayson tried to get Finn to talk, Finn still didn’t have enough courage to say anything. He continues to stay in the same curled-up position as before, hiding his blushing face behind his knees whenever he got shy. Only this time, he was smiling and giggling a lot more than before. But it still wasn’t enough to get Finn to fully talk to Grayson.

Although it pains Grayson to see Finn act so timid around him, Grayson can’t help but to admire Finn’s fragile little pale body. It oddly appeals Grayson to see Finn curled up into a tiny little ball with his blushing red cheeks every time Grayson try’s to talk to him. Before he knows it, he has been staring at Finn’s cute lil delicate body for longer than he thought. Grayson quickly gains conscious again and immediately snaps out of it while clearing his throat.

“It’s strange…” Grayson’s girlfriend says. “Finn’s usually never THIS shy whenever he meets new people. I don’t know why he’s acting this way with you.” She wonders.

“Damn. I guess he just doesn’t like me…” It hurts Grayson to admit it.

Little does Grayson know…

-Grayson’s POV-

A couple hours went by and my girlfriend was kind enough to let me shower at her place since the water at my place got cut out.

I have given up in trying to make friends with my girlfriend’s lil brother. All I can do is hope that with enough time, he’ll eventually warm up to me. Thinking of ways to make him like me is only stressing me out even more. I don’t wanna sound over conceited or anything, but kids usually love me. I’ve never had a problem bonding with a kid before until now. It feels like I’ve tried everything but yet nothing has worked on Finn.

I’m starting to become desperate for Finn’s approval that I’m honestly willing to do ANYTHING to make him like me. I know I may be entering pretty risky territory for me to be saying ‘anything’, but my persistence is strong. Besides, Finn is a shy little kid who is barely learning how to read full sentences. How hard can it be to gain his approval?

That’ll have to wait though. Right now all I need is a nice cold shower to help me cool down and take my mind off things. I turn on the shower head and adjust the water to the perfect temperature.

I strip off all my clothes, throw them in a messy pile on the floor, and enter the shower with my soft 6 inch dick swinging back and forth between my legs. The refreshing water hitting my pecs and trickling down my abs causes a relieving sensation. I throw my head back and let out a deep moan of satisfaction while I rub on my wet glistening body.

My hands explore further down my glazed muscular body and find their way down to my semi-hardened 8 inch cock. I begin to pull and stroke on it while leaning my head back in lust and enjoying the water soaking into my skin. After several stressful hours, I finally have time to relax and savor some alone time. It didn’t take long for my shaft to get fully rock hard. So much blood is pumping into my cock that the veins are popping out more than usual, my red/pinkish mushroom head is fucking huge and throbbing like crazy. I use both my hands to grip onto my fully enraged 11 inch cock and stroke on it much more aggressively than before.

Ugh, I can’t take it anymore.

My arm reaches out to grab my phone from the counter, and quickly tap on my girlfriend’s contact in messages.

I then click on the camera icon and press record. I pan the phone up and down my entire wet body with one hand, while the other hand is slowly but passionately jerking my massive veiny length. I even wave it around a bit just to tease her.

I end the recording and immediately send my girlfriend the video. With the caption ‘Come join me in the shower ;)’

I place my phone back down on the counter and continue jerking off while letting the warm shower water soak my entire body and hair. In preparation for my girlfriend to join me any second. I know it may be a bit risky doing stuff like this in her parent’s house, but I promise it’ll be fast. Her parents wont even notice that we’re missing. I’m just so fucking horny right now, all I need is a quick relief.

Besides, the thought of having sex in my girlfriend’s PARENTS house gives me a huge rush of thrill and excitement knowing that we can easily get caught at any second while I’m banging their daughter in the shower. It’s making my dick throb like crazy just imagining it. Which is also getting me very impatient within each passing second that she isn’t here yet.

-Third Person POV-

Grayson closes his eyes and rubs on his meat much faster than before while fantasizing of all the different positions he could fuck his girlfriend in that shower. “Ahhh fuckk~” He slightly groans as he continues beating his meat furiously. Grayson was so caught up in the moment that he didn’t even realize he was no longer alone in the shower until he felt a hand grabbing onto the tip of his big white cock which triggered him enough to shoot out massive thick loads of cum. “OH FUUCKKK!” He moans in lust whilst an uncontrollable amounts of sperm keeps on shooting out his dick. None stop orgasms like a fountain.

With heavy breathing, Grayson opens his eyes with a giant smirk on his face, expecting it to be his girlfriend in front of him. But instead, there was absolutely nobody.

“What the-?” He says in utter confusion.

‘I swear I’m not tripping out… am I?? I could’ve sworn I felt a hand wrapping around the tip of my dick.’ He thinks to himself as he starts to believe he’s loosing his mind.

He abruptly looks down at his shaft only to be greeted by his girlfriend’s little brother Finn, who was butt naked in the shower with thick loads of Grayson’s cum splatters all across Finn’s innocent little startled face. Finn’s cute little body freezes in surprise, processing the mysterious white liquid that Grayson shot on his face.

Grayson was on the verge of choking on his own disbelief as he couldn’t even bare to witness this truly startling scene. He immediately try’s covering himself but it was a struggle trying to hide all of his fully-hardened length with only his two hands.

"Finn!" was the only word he managed to utter, still completely in shock. “What are you doing here?!” He shouts in panic.

Finn and Grayson differ greatly in size. Grayson’s muscular tan body is clearly much more bigger, taller and stronger than Finn’s fragile little skinny pale body. Heck, even Grayson’s biceps is the same size as Finn’s entire head! It’s no surprised why Finn was acting so shy around Grayson in the beginning. If you were a vulnerable 3’4” cute little boy, you would also be intimidated to talk to a giant 6’1” hot hunky beast like Grayson too.

So to see Finn eagerly volunteering himself to be butt naked in the shower with Grayson truly shocked him.

“Why dud you pee all ober my fwace?” Finn giggles from the unexpected surprise as he uses the palm of his hand to wipe off a large thick chuck of Grayson’s creamy load off his cheek. He brings the cum up to his face and carefully observes it. “And whay is it so white and gooey??” The innocent boy had a numerous amount of questions to this intriguing new world he has stepping into.

“No no no, don’t touch it! Let me wipe it off of you.”

With quick hand gestures, Grayson tries to remove his sperm from Finn’s possession, but it was too late.

Little kids will put just about anything in their mouth, especially if they are told not to. And Finn is no different. Finn shoves a big scoopful of Grayson’s load into his tiny mouth. His eyes widen from the unexpectedly delicious taste. He laps up every last drop of cum from his tiny hands. The taste of Grayson’s man-milk has sparked a new form of desire that Finn never knew he needed until now. Reaching a new peak of curiosity.

“NO DON’T EAT- it…” Grayson is in lost for words.

‘Holy shit… How did this happen?!’ Grayson thinks to himself as he clears his throat. ‘He’s a kid… My girlfriend’s little brother… I barely met him a couple hours ago and now- and now he’s in the shower with me, eating me cu- FUCK! What the fuck am I gonna do?!! I know I said I wanted Finn to get along with me, BUT NOT LIKE THIS!!’

“Little kids like you shouldn’t be eating that!!” Grayson shouts. His heart races in panic by the thought of all the potential consequences that could occur if anyone found out about this incident.

“Mmmmm why not?? It taste yummy!” Finn licks his lips with a giant smile on his face.

“Because! It’s only for adults.” Grayson gives Finn a short and simple respond in hopes that he no longer ask any more uncomfortable questions. “Now c’mon, please get out of the shower so I can dry you up and pretend like nothing happened, ok? We can play with that toy car I gave you if ya like.”

“Bu-but… you towld me that I can join you in da showur…” Finn whines. “I don’t like pwlaying wit cars! I like plwaying wit Barbie’s and coloring! …and I also like being in da showur wit you Mr. Grayson.” He says mumbles shyly as his cheeks turn rosy pink.

Seeing Finn so bubbly and outspoken was surprising. Especially considering the fact that Grayson was convinced that Finn didn’t like him. It made Grayson’s heart pump with thrill and excitement knowing that his girlfriend’s lil brother is starting to finally like him now, but is it really worth it?

“What are you taking about?? I never told you to come in the shower with me.” Grayson states, while continuing to miserably fail at hiding his ginormous pump-machine cock from the little boys view.

“Yes you did!” Finn corrects him. “I was pwlaying games on big sissy’s phone when you sent a bideo of your pp in the showur. And you said dat I can join you!” Finn explains. His cheeks turn red as he finally gets the courage to look up at Grayson’s large towering body, with his huge cock that is a tad bit higher than Finn’s eye level.

“Oh god.” Grayson facepalms as he now fully understands this unfortunate predicament that he put himself in. “Finn… YOU weren’t suppose to see that video. Those messages were meant for your sister to see. My girlfriend.” Grayson clarifies. “Now let’s please get out of the shower now.”

As Grayson was about to exit the shower, Finn quickly wraps his arms and legs around one of Grayson’s leg. Clinging himself and putting all his weight up against Grayson’s leg, like if he was a sloth hugging on to a tree truck. Which prompts Grayson to come to a complete halt.

“Noo! I don’t want you to be her boyfwend! I want you to be MY boyfwend so I can plway wit you in the showur forevea and everur!” Finn admits, while looking up at Grayson’s eyes for the first time.

“Wait, what?!??” Grayson exclaims.

Finn hops off of Grayson’s leg once he realizes that Grayson has stopped budging to leave the shower. He stands directly in front of Grayson with his head looking up at him.

It is terrifying for Finn to see Mr.Grayson’s tall, fully exposed ripped body, completely wet and glistening from the warm shower water. His wet oily skin enhances Grayson’s large beefy pecs, his sexy abs, his massive biceps that constantly flex whenever he moves his arms, and not to mention his colossal, girthy, veiny, monster cock. Which is even thicker than Finn’s tender little arms.

It was all very overwhelming for Finn to witness, especially when viewing him from such a low angle. But for some odd reason, he couldn’t look away. Finn’s eyes were glued to Grayson’s body. Too mesmerized, too captivating to look away. It began to make Finn’s smooth bubble butt twitch and his young lil cocklet to throb at the sight of Grayson.

These were all new emotions for lil Finn, unsure of how to deal with these new desires. All he does know is that within each passing second that he stares at Grayson godly body, the less scared he gets, and the more hungrier he becomes.

“Can I pwease have mour of your mwilk mistur Grayson?” Finn begs in desperation as he feels his mouth beginning to salivate the taste of Grayson’s creamy load again.

“Huh?! Milk??!!!”

“Ya! It was white like mwilk but a bit mour sweetur!” Finn giggles.

Not a second later, Finn’s little innocent hands reached out and successfully grab the tip of Grayson’s semi-hard horse cock. Even with the help of his two little hands, it still wasn’t enough to fully wrap his fingers around Grayson’s girth. But that didn’t stop Finn. Before Grayson could even have a chance to react, Finn forcefully shoves Grayson’s big pink tip all inside of his little cock-hungry mouth.

Grayson’s entire body flinches and his cock starts to throb uncontrollably as he lets out a quiet moan of shock. Chills run across Grayson’s whole body by Finn’s unexpected action, which floods Grayson’s head with many guilty emotions. “YO WHAT THE FUCK ARE YOU DOING?!!!” Grayson uproariously shouts in a deep, concerned voice. He didn’t mean to curse in front of the little kid, or let alone raise his voice so loudly at him considering that he just barely met the kid, but Finn caught him so off guard that it just unconsciously slipped out.

Finn gives no response and continues to suction onto Grayson’s cock head like a magnet. Too in love with how Grayson tastes like. His tiny mouth was doing an impressively good job at taking a huge chunk of Grayson’s girthy mushroom head down his throat. Finn’s pale little cheeks expand by almost triple in size by how much man meat he is stuffing his starving little mouth. His entire face turns bright red.

Grayson tries his hardest to resist the guilty temptation. But no matter how hard he tries, his slowly expanding cock exposes the cold hard truth.

“Finn-“ Grayson moans as he struggles to push Finn away. “Let- go..!” He groans. But Finn doesn’t budge.

Grayson looks down at Finn who is sucking the head of his cock. Feeling dizzy by the overwhelming stress, he slides his hands through his wet hair, striving to maintain his composure as he feels the blood pumping all across his throbbing veins from every inch of his wet beefy body. 

He is in great disbelief. Unable to process this shocking turn of events. 

With great amounts of anger and devastation… “I SAID LET GO YOU PEICE OF SHIT!” Grayson uses his strength to forcefully break free from Finn’s mouth.

When his dick finally pulls out of Finn’s insane suction of a mouth, at least 6 or 7 insanely thick threads of pre-cum connected Finn’s plump lips to Grayson’s cock head as he pulls farther and farther away from Finn. The tip of his cock was coated in a thick mixture of saliva and pre-cum creating a natural lube.

The strands stretch longer and longer as Grayson separates himself away from Finn, but yet no matter how far Grayson separates himself, the pre-cum strands do not break apart from the two of them. It only stretches even longer and longer as Grayson backs away.

That was the least of Grayson’s concern though. He’s just relieved that he managed to break free from Finn’s mouth.

“Finn… I’m sorry lil guy…” Grayson pauses to catch his breath, “Let’s just please forget about this and play with your toys or something.” He continues to pant heavily from the overwhelming amount of sensation that he experienced in the last few seconds. Grayson tries his best to convince lil Finn to stop acting so seductive, not because Grayson doesn’t like it… but because he LOVES it. But he’s afraid of what could happen if he goes along with Finn’s devious little actions. Which is why Grayson tries everything in his power to control his sinister temptations and avoid making any sort of eye contact with Finn’s perfect lil irresistible body.

Grayson’s chest puffs up as he continues to breathe heavily as he runs both of his hands through his hair and rests them on top of his head. Debating what to do next.

Finn, on the other hand, was having the time of his life. He licks his lips, savoring Grayson’s delectable sweet and salty taste. He has never felt a more rush of crave and excitement in his entire few years of living. All the fear and timidness he felt towards Grayson has suddenly all disappeared.

“I want moure!” Finn turns into a thirsty lil brat, letting his cravings take control of him.

“No Finn, that’s enough! You shouldn’t even be tasting that!” Grayson firmly replies, while being completely on-guard. Just in case Finn tries to pull a fast one on him again.

“BUT I WANT MOURE!” Finn raises his voice, not accepting ‘no’ for an answer. Finn raises one foot and stomps it heavily on the ground in frustration with his tender lips protruding. His posture is assertive, with his small hands placed firmly on his hips while looking up at Grayson, locking eyes with his.

“I said, NO!” Grayson growls, standing his ground. Annoyed at Finn’s spoiled lil attitude.

“Wahhhhhh~” Once Finn realizes he can’t get his way, he throws himself on the wet slipper floor of the shower and starts to burst into tears. Crying like a literal baby.

If there’s one thing Grayson hates more than spoiled little kids, it’s little kids that cry while throwing a tantrum. Something about hearing their annoying lil high pitched wails makes Grayson want to do unspeakable things to them. But that’s all in his head of course. He has never actually harmed a kid before. He’s Grayson Dolan after all. An extremely famous, well-known YouTube influencer with millions of fans. He has way too much to lose.

Grayson has been doing a good job at being the ‘adult’ in this whole situation, but this was his final straw. He couldn’t take it anymore. Too many emotions happening all at once. It was impossible to hold back any longer.

“Fine.” He says in a deep, low, dangerous voice while his blood begins to boil.

Grayson approach’s Finn and grabs his fragile lil body with one hand and throws him over his shoulder like nothing. Finn stops whimpering once he feels the touch of Grayson’s big large hand wrap around his entire thin waist, and scoops him up off his feet. Not a second later, Grayson presses the left side of Finn’s face against the shower wall. His body is completely smushed as his eyes try to look back at Grayson.

With one hand Grayson grips on to the back of Finn’s neck, while the other pushes his dangling little legs apart.

“Ah~ mistur Gwayson, what are you dewing?”

Grayson presses his big beefy pecs against Finn’s back which causes Finn to gasp in ecstasy. Grayson leans in so close to Finn’s face that Finn can feel Grayson's breath on his skin.

“You wanna act like a little slut, then I’ll treat you like one.” He whispers in Finn’s ear which creates chills all across Finn’s helpless little body. He is scared by how aggressive Grayson is acting all of a sudden, but for some weird reason it’s turning Finn on seeing Grayson get so dominant. He’s not sure if he should be screaming in fear, or screaming in pleasure.

Grayson slowly works his lips down Finn’s tiny pale body. Leaving a trail of wet kisses as he travels along. It tickles Finn, but in the best way possible.

Once Grayson reaches what he was been desperately yearning for, he doesn’t hesitate and buries his face between Finn’s glistening bubble butt. Grayson forcefully spreads Finn’s cheeks apart with his strongly defined jaw as he savagely eats on Finn’s kiddie hole. Like if he’s some sort of wild animal who hasn’t eaten in weeks.

“Aughh~ Gwayson!” Finn moans in pleasure.

Grayson’s long thick tongue pushes through Finn’s impossibly tight, virgin hole. Stretching it open and sliding his powerful tongue through. Getting a taste of Finn’s sweet boy hole.

“Aaugghhhh~ OH Gwrayson!!” Finn moans even louder as he feels a greater pleasurable sensation the further Grayson sticks his long tongue down his rim. Grayson pushes deeper until eventually, his tongue is hitting Finn’s g-spot. Finn’s eyes roll all the way back as a giant drooling smile forms on his face from all this intense lust and satisfaction Grayson is giving him. He places one of his petite hands behind Grayson’s head to push his face deeper between his own cheeks. Endorsing Grayson to go hard. Never wanting him to stop.

The more that Grayson tastes Finn’s innocent sweet tush, the more hungrier he gets. He becomes more aggressive with his kisses and licks, his breathing gets heavier and more uneven as his excitement builds. Grayson’s face is completely suffocated between Finn’s bums at this point. But yet he’s enjoying every second of it. His massive veiny hand slaps and squeezes Finns bum while the other hand continues to pin Finn up against the wall with his little feet continuing to dangle in the air.

After Grayson has gotten Finn’s tiny boyhole all wet and lubed up, he finally slips his long tongue back out and stands up. Carrying Finn with both hands by his waist.

Finn whimpers in disappointment when he no longer feels Grayson’s divine tongue inside him.

“Goddamn you taste so fucking good” Are the first words Grayson says after thoroughly eating Finn’s ass out, while completely out of breath.

‘I guess I really am a pedo after all.’ Gryason admits to himself. ‘No going back now.’

Finn isn’t entirely sure what Grayson means when he says that he ‘tastes so good’, but he uses context clues to figure out that it’s a good thing. So he just rolls with it.

“Dew I taste bettur than your girlfwend?” Finn blushes in embarrassment by that question. But he desperately wants to know who Grayson prefers. Him or his older sister.

“WAY better than my girlfriend” Grayson doesn’t hesitate. He bites his lips as he craves more of Finn’s mouthwatering ass.

“Yayyy!!” Finn cheers in joy. Enthusiastic by Grayson’s response. “Can you pwease dew it again! Pweeeeasee!!” Finn begs for more.

“I see you’re still a thirsty little slutbag. Aren’t ya?” Grayson aggressively clenches his teeth while speaking. “Well here’s something else to shut you up.”

With one fell swoop, Grayson turns Finn over to face him, pushes him up against the wet shower wall, spreads his legs apart, and aligns his still fully erected 11 inch veiny cock to Finn’s tiny wet boy hole. Finn has no choice but to stare up at Grayson’s glistening muscular body. Starting from his v-line, to his abs, chest, and up to his cocky defined face. Sending a spark of rush and excitement all across Finn’s smooth pale little body. Which is way less than twice the size of Grayson’s body.

Grayson’s face is filled with lust and aggression while a devilish smile begins to form, his eyebrows draw together creating a V-shape, casting a stormy expression over his eyes. He looks at Finn’s innocent little baby-face, completely clueless as to what is about to happen.

“Mistur Gwayson. What are you dewing?” Finn giggles as he feels the tip of Grayson’s extra long cock head rubbing up against his tight lil rim.

Grayson didn’t answer him though. And before Finn could get another word out…

BAMM!

With great force and strength, Grayson slams his incredibly thick veiny monster cock deep inside Finn’s tight little virgin hole. Penetrating his tiny insides.

“AH!” Finn yells in panic as his eyes open wide in shock by how far Grayson is stretching him. Finn’s boy hole is being stretched to limits he never knew could be humanly possible. It’s literally taking his breath away.

The circumference of Finn’s microscopic rim squeezed so hard on Grayson’s gigantic horse cock “HOLY FUUUCKKKK!!” causing him to moan uncontrollably from the biting pleasure. No longer caring who can hear him.

Grayson is equally as shocked by the sight of such a tiny little fragile boy being stretched open so wide. But it turns Grayson on knowing that it was his own cocks doing for the damage that is being done to that teeny little kiddie hole. He holds onto Finn’s thin waist with both hands as he forces more of his length inside him. “FUUUCCCKKKKKK!!!” Grayson throws his head back as he lets out another loud powerful moan of pleasure the deeper he forces himself inside.

When Grayson is a good 6 inches inside, he begins to thrust in and out of Finn’s compressed kiddie hole. Allowing his hips to seductively move forward and back the more he grinds on Finn.

“Ouchy Gwayson! Your pp is too big!!” Finn whimpers.

“But you had no problem shoving it in your hungry little mouth a couple seconds ago.” Grayson responds in a teasing tone.

“But- ahh~ but-” Finn is in a lose for words as the pain is making him loose concentration.

“This is what happens when you act like a thirsty little slut for my big boy pp. Adults like me can’t help it when little boys like you act all seductive, showing off your cute petite body and smooth lil bubble butt. It makes every adult male like me go crazy for it. But I have a feeling you already knew that. You knew exactly what you were doing, hopping in the shower with me, getting all naked to tease your cute little delicious body just so you could get your way with me. I’m not stupid.” Anger builds up in Grayson’s body, causing him to thrust even deeper inside of Finns torn up hole.

“AHH~! I’m rwelly sowwy! I don’t know why I did it!” Finn lied. He knew exactly why he did what he did. Because Grayson Dolan’s good looks were too irresistible for Finn to keep his hands and mouth to himself. In that little amount of time that Finn first met Grayson, Finn developed a huge crush on him that led him to get introduced to a ton of different new emotions Finn has never felt before about anyone.

Finn is too embarrassed to tell Grayson that not only does he like him, but he LIKES likes him.

“Don’t say sorry now.” Grayson says while continuing to grind deeper inside Finn. “It’s too late for that.”

“Owwieee, pwease stop, it’s too big!” Finn’s eyes widen in fear as he literally feels his ass getting ripped apart. But what panics Finn even more is that when he looked down at himself, he could literally see Grayson’s gigantic horse cock bulging out of Finn’s own STOMACH! You could even see the veins of Grayson’s cock bulging though.

“Yeah, see. Doesn’t feel so good when you tell someone to stop and they keep going, does it?”

“I’m sowwy! Pwease!!” Finn whimpers.

Finn is so tiny that his eye level can only reach up to Grayson’s chest while he is being railed by him. Grayson leans one arm against the wall, revealing his hair pits, while the other hand carries Finn so lightly and effortlessly by the hips like if he’s some sort of fleshlight. Grayson then proceeds to arch down and slide his tongue inside Finn’s sweet tiny sobbing mouth to calm Finn down. And just like magic, Finn has stopped crying as he found a sensual comfort from kissing Grayson’s long thick tongue with his tender sweet lips. Grayson’s head is nearly twice as big as Finn’s but that didn’t stop them from passionately making out with each other. With Finn’s small hands clinging onto Grayson’s cheek.

This last for a couple minutes of endless lust, kissing hard and messier within each second that passes. Grayson keeps on squeezing deeper and deeper inside Finn’s boy hole, but surprisingly, Finn is managing to deal with the pain. The more he sucks on Grayson’s lips, the more he is able to find pleasure in the penetrating pain of Grayson’s fat cock buried deep inside his stomach.

Once Grayson slips his tongue out of Finn’s throat, he pushes Finn’s face between his large hunky pecs. “Fuck yeah baby, suffocate on my chest.” Grayson says while continuing to fuck him.

Finn doesn’t hesitate to put his tiny (but extremely thirsty) tongue to work on Grayson’s big voluptuous chest. The taste of his masculine salty flavor and the aroma of his musky scent was more than enough to keep Finn highly entertained. He travels down to one of Grayson’s harden brown nips and begins sucking on it like if he was a baby getting breastfed. Sucking and nibbling on them, making them even harder.

Finn was so distracted on Grayson’s nips that he didn’t even realize how hard Grayson was fucking him.

In and out, in and out, goes Grayson on Finn’s unbearably tight hole. Going twice as faster than before. Grayson’s massive cum-filled balls slap against Finn’s ass so hard, creating a loud “Plat! Plat! Plat! Plat! Plat!” sound the harder and faster Grayson fucks him.

Grayson has never fucked such a hole so small and tight in his entire life before, not even his own girlfriend’s was this tight. Heck, even Grayson’s THIGHS are thicker than Finn’s entire skinny little kiddie body. Grayson Dolan has never imagined that he would ever be fucking a little kid in his entire life before until today. But he doesn’t regret it one bit. His adrenaline keeps rising higher and higher every time he thrusts into that tiny boy pussy.

He starts fucking Finn so hard that even Finn is having trouble composing himself.

“Aughh~ Ahhh~ Oh Gwayson! Ahh~ Mmm~ Ahhh~!” Finn moans, as he finds himself surprisingly enjoying this strange feeling. The pain is still intensely strong for Finn (especially for a tiny little kid like himself), but the way that Grayson is railing him so passionately and so incredibly well is making Finn experience twice as much pleasure than pain.

Grayson is a fucking-machine! Not only is Grayson thrusting himself harder inside of Finn, but he is holding onto Finn using both his hands and slamming Finn’s tiny miniature body up and down on his big dick. Fucking Finn like a literal fleshlight. All while the running water from the shower hose trickles down both their bare bodies. Grayson’s messy wet hair is all over his face, covering his eyes, but that doesn’t stop him from plowing the shit out of Finn’s torn up kiddie hole like a savage horny beast.

The harder Grayson fucks him, the more and more Finn’s head begins to bob up and down, his entire body begins getting loose and flimsy from the fierce pounding. Struggling to maintain control over the weight of his own body. His tiny little hands holds onto Grayson’s strong broad shoulders to stabilize his floppy body from the intense drilling.

Oddly enough, Finn begins to feel a blend of discomfort and anticipation from the lower part of his stomach. Whenever Grayson thrust hard inside of him, Finn has a yearning urge to pee. His little cocklet twitches and throbs while Grayson, “PLAT! PLAT! PLAT! PLAT!” fucks him harder and harder each time.

Finn tries his hardest to resist the urging sensation the best he can. Unsure as to why he suddenly feels the need to pee. But the harder and faster that Grayson pounds him, the more difficult it gets to contain it.

“OHH FUCKK! FUCKK! FUUCCKKK!!” Grayson’s groans become more louder and violent than ever before, echoing across the entire room. His thrusting gets more powerful and aggressive. The slapping sounds of his big wet balls slapping against Finns bum also become profoundly louder and faster.

* PLAT!! PLAT!! PLAT!! PLAT!! PLAT!!*

Finn claws his fingernails deep into Grayson’s skin as he grips on to Grayson’s shoulder like if his life depended on it. Trying his hardest to hold on and control his bladder from peeing, while Grayson continues to be a savage fucking-machine in Finn’s guts. Completely balls deep inside him.

Finn whimpers as it becomes nearly impossible to hold it in any longer.

“Mmm~ ahh~ mmm~” Finn moans in utter satisfaction as his lil cocklet sprays out tons of pee all over himself and Grayson’s body. Grayson didn’t seem to mind as he kept plowing Finn balls deep which made Finn pee even more from all the sensational pleasure he was feeling.

“Ahh~! Gwayson~! It feel soo good!” Finn lets out another moan of thrill while he places his lil hands on the upper part of his own stomach so he can feeling Grayson’s large girthy cock penetrating inside his intestines. It was such a surreal but mesmerizing feeling for lil Finny. He is loving every second of this terrifying but yet extremely pleasurable experience. Watching and feeling Grayson’s masculine energy completely dominating and obliterating him is such a turn on for Finn.

“GHAAAAA! AUGHHHH FUCKKKK!!! AUGHHHHH!!” Grayson uses his whole chest to let out several roaring alpha moans that can be heard from the entire house. “ALMOST THERE BABY!!” He sounds completely out of breath, but that doesn’t stop him from being a true alpha male. It feels too good to even stop.

*CLAP!!! CLAP!!! CLAP!!! CLAP!!! CLAP!!! CLAP!!!”

Grayson presses Finn up against himself and firmly wraps his big muscular arms around Finn’s small pale body, tightly hugging him as he prepares to shoot the biggest cumshot of his entire life. Grayson rest his chin on top of Finn’s tiny head as he closes his eyes shut while moaning profusely.

He slams one final giant thrust, balls deep inside Finn. Before he knows it, he reaches full climax and erupts ropes beyond ropes of thick warm cum flooding the insides of Finn’s used and abused kiddie hole. “FUUUUCCKKKKKKK!!!!!!!!!!” Grayson exclaims. His dick was a never ending cum-fountain shooting out gallons of thick creamy hot cum inside of his girlfriend’s tiny underaged little brother.

Grayson wasn’t the only one having an ultimate exhilarating experience. Finn was also getting a strong sensation from the feeling of Grayson’s powerful explosion of warm cum all buried deep inside his guts. It made his body feel all warm inside.

Gallons of cum continues to shoot out of Grayson’s meat pole and into Finn’s body. It didn’t take long for Grayson to successfully fill every inch of Finn’s insides with his thick man-cream. It overflows and gushes out of Finn’s tiny boy hole and drips back down to Grayson’s long veiny cock. Finn was completely bloated with Grayson’s cum.

Grayson’s arms are still tightly warped around Finn’s whimpering body while he continues to cum inside him. Finn is completely smushed between Grayson’s sweaty muscles but is loving every second of it. The two of them stay in that exact position for a good couple minutes, taking it all in while they pant loudly.

Finn was also no longer jealous of his older sister. Because Finn will always know that his older sister’s boyfriend prefers him more than her. Finn got everything he ever wanted plus much more. Grayson introduced Finn to a plethora of new exciting emotions that he never knew he could feel about someone else. And now that it’s over, Finn’s only wish is for Grayson to do it again with him.

‘I can’t believe I just did that… with a little kid…’ Grayson thinks to himself completely mortified as he is barely gaining his conscious again. It’s like his body took control of him for all that time he was fucking his girlfriend’s little brother. But as much as he hates to admit it… he doesn’t regret it one bit.

“Grayson??” Grayson’s girlfriend knocks loudly from the other side of the bathroom door.

Grayson didn’t realize that she was knocking on the door for a while now ever since she heard loud thumps and groans coming from the bathroom. Grayson was too busy to hear her until now.

“That’s it, I’m coming in!”

It was too late for Grayson to think fast and hide Finn. Even if he did have time, he hardly has any energy to do any fast movements. Nor did he even care.

She opens the door wide and lets out a giant screech when she sees the horrific view in front of her. Her little brother being penetrated by her boyfriend’s giant horse cock balls deep in him in the shower.

“What are you doing to my baby brother??!! Let him go!!” She commands. Still unable to process what she walked in to.

“Fine.” Grayson says while continuing to pant heavily. “You want him? Come and get him.” He says, untangling his arms from Finn and putting them up to his head in a surrendering position. “Noooo…” Finn whimpers. Not ever wanting to leave Grayson’s mesmerizing body. Grayson was carrying Finn the entire time, so once Grayson lets go of him, it was expected for Finn to fall to the floor. But he didn’t…

Grayson’s cock is so far deep inside Finn’s stomach, that Grayson no longer needs to hold onto Finn to keep him on his cock. Finn remains in the air without the help of Grayson’s hands to carry him. Grayson’s giant hard cock penetrated balls deep inside him was enough support to carry Finn’s entire petite little body.

Grayson is literally WEARING Finn.

“C’mon.” Grayson lets out a sinister cheeky grin as he gestures his girlfriend to come closer. She slowly walks towards them, but is spectacle. Unsure of what to do.

“You wanna save your baby brother, don’t you?” He asks her. “Then come pull him out of my big white pedo dick.”
