Hello All!

I’m Cocoa and I’ll try my best attempts at writing Sonic Smut, or at the better end of the rope, TRY to write Mpreg. Don’t worry though, I’ll clear some things up with the fact that in this, Sonic is Trans (FTM) who only went through Top Surgery and is saving up for Bottom Surgery! Speaking of which, Shadow DID helped him and still shows his way of supporting him (Hence the Cafè job).

Is Knuckles his current crush and will get together in the end? I guess we’ll have to see!

By the way, ‘Ignore’ the other relationships ;p

That is all and I hope you’ll enjoy it! :3

Goodbye!

~ Cocoa

Chapter Text

“Hmm, It appears that this must be the place, a much pathetic-looking place.” The jackal growled before taking a deep breath in and sighed. “However, this will do for now, considering that…Nevermind. Let’s get this over with.”

As the jackal walked up to the apartment complex, he stopped and admired the rather lack-of-charm aesthetic of the building. It had a few visitors with some having small potted plants, and rugs that were hanging to dry, the color of it being a creamy beige with a dark shade of red tiles to pull him further as he hoped that this place would make his mind get away from the drama of his old home.

However, that wasn't his interest.

His interest was piqued as soon as he saw two mobians walking out of an apartment smiling and appearing to be in the middle of their conversation.

One was a red Echidna that had a black tank top and a pair of dark brown shorts that hugged a familiar face, one that the Jackal knew couldn't believe to see, A blue hedgehog wearing a loose White T-shirt with baggy black knee-length shorts underneath. That face and those quills immediately made him think of another hedgehog, Shadow.

Shadow was with that same Blue hog back in High School. Sonic. The Jackal’s fists trembled before sighing deeply and made his way to find his apartment number.

Of course, Why pull such a sick prank like this one?

A few days passed since the new addition to the Apartment complex, Sonic was walking down the path toward the park before being stopped and began talking with Amy and Blaze. They were all mentioning the new guy, mentioning how weird and strange he was acting around them. “Huh, well I figured I’d bake something for him to get settled but he always refuses!” Amy frowned, crossing her arms with an eyebrow raised.

“I’d love for him to watch the annual Royal dance but Alas I got the same treatment as Amy,” Blaze pondered before shaking her head in disappointment. “Perhaps he’s introverted?”

“Whatever the case may be, Tails could probably have him out of his apartment in no time!” Sonic smiled cheerfully, putting his hand in his pocket. “Besides, who couldn't refuse his smile?”

“Well, you are pretty… Confident, Sonic. I’m not surprised! You always are,” Amy nodded in agreement before hesitating to go with it. “But, are you sure about the Tails trick?”

“Amy, come on, Little buddy can handle talking it out with the Rookie!”

While the hedgehog boosted on his little brother, the Jackal walked by as if he was ready to pounce on the blue fur before Sonic turned around and saw him with a beaming smile. “Ah! I knew it, Tails dragged you out here, Rookie!”

“Quiet down, Hog. What's your boring conversation about?” The Jackal snapped at him, which caused Amy and Blaze to walk off to give them privacy. “By the way, it's Infinite, not Rookie.”

“We’re, well were, talking about how you were causing some concerns about being a bit hostile with the others!”

“…What, That's all?”

Feeling unsettled about how he responded, Sonic raised a brow and folded his arms. “‘That’s all’? Look, man, you need to be careful with your words, otherwise, you’ll end up not having any friends.”

“Hmph, unlike you, I would rather be on my own and deal with my problems with no distractions.” Infinite scoffed before feeling his anger rising as the blue hedgehog leaned in with a stern facial expression.

“You may enjoy being hostile, but that’s no excuse to treat my friends like they are your doormat! Oh and also I’ve heard that someone tried to do the same thing but ended up getting a taste of Karma, possibly it's a relative of yours?” Sonic ranted, noticing the gradual change in Infinite’s facial expression as he tried to keep his composure. “So, are you aware that what you are doing is gonna make you a Lone Wolf, Finite?”

The Jackal snapped, clenching his jaw as gripped ahold of the Fur by his neck and slammed him against the wall. Hearing the words, lone wolf, ringing in his head made him remember his old life that he wished to have forgotten. “You…Rat—!” he raised his hand in the air before it was stopped.

Sonic, despite being ready to fight back, glanced up and noticed that it was Knuckles who had a hold on the Jackal’s wrist. It was the stern Echidna that prevented him from hurting the hedgehog. The Blue Fur felt his heart beating and flushed slightly, before snapping out of his head. Infinite yoinked his wrist away from Knuckles, his aggression rising further. “Go any further, Infinite, then It’ll be a problem.”

“Hmph, of course, you’d come to your Rodent’s aid. Your pathetic friends will become spoiled because of your treatment towards them.” Infinite turned away from them and began walking off.

“I think you are wrong, Finite, you don’t understand how friends work! Knuckles is a great guy for your information!” Sonic was prepared to start another fight again before the Red Echidna stopped him again. Infinite turned around and scowled at the hedgehog. “We’ll meet again, Sonic...”

“Go on ahead, I’ll talk with Sonic.”

The Jackal, scowling with hatred, continued walking away as he noticed a few bystanders observing the conflict. “Quit gawking around! Get out of here, you imbeciles!”

Once the two were left alone, Knuckles turned to face the blue fur with concern. “You went overboard just now, Sonic.”

“I know, I’m sorry, it's a bad habit.” Sonic lowered his head, letting guilt settle in him.

“There’s nothing wrong with telling people that they are wrong, but with you being so confrontational and possibly being so harsh, they may listen to what you have to say,” The Echidna put his hand on Sonic’s head, patting it. “But, Thank you for sticking up for me.”

The blue fur flushed heavily and his eyes lightened up, his heart beating heavily. Knuckles is, to him, the only person who sees him besides Amy and Shadow. The only one who could handle anything in his situation and come to a conclusion.

A few minutes later, Sonic was in the Café where Shadow worked. He stretched his arms as he was in the middle of writing something on a computer before he was caught off guard by the hedgehog again. “Oh, you are still here?”

“Ah! Shads!” The Blue Fur glanced up as Shadow poured in a refill of coffee. “I thought you were…?”

“On my break? I wish,” He grumbled. “Hmph, where’s that damn Redhead?”

“Knux? Oh, Uhm, he had some business to deal with Rouge and Big, they got into another argument again.”

“I see, it's always with her, and that Cat.”

“Hah! It's okay, I have time to work on this email for him, so it's fine!”

Sonic felt his heart fluttering, despite that Shadow and he were a one-time couple back in high school, he never had any hard feelings for him. He felt like he could go on for an eternity with him by talking to him, not just with him but also with even the mention of the Echidna just made his feelings for him grow more stable. “Oh, speaking of which, I’m planning on speaking with him once again at that party.”

“You finally decided to get out and have a bit of fun, Shads?” Sonic teased.

“Don’t even mention it, Rouge invited me to it just so she won’t be alone.”

“Wow, imagine that you wanted to bond with Knux to the point that you had to bring Rouge, huh?”

“That's not even close to what I had in mind.”

Sonic laughed. “Well, in that case, I’ll make sure you have the best time!”

Shadow scoffed, putting his hand on his hip. “You’re too energetic, Sonic, but you always do this so I’m not surprised anyway.”

The blue fur smiled at the hedgehog just as he was about to go back to the station or help out any other tables. “Well, I’ll be avoiding the manager’s nonsense, so if you don't mind come and tell me what time I should arrive, Faker.”

Sonic smirked. “I heart you too, Shadow.”

“Just don’t…overdo it, Sonic.”

With a confident smile, Sonic left a tip for the hedgehog as he gathered his things together before pulling out his phone and reading the message he got from Knuckles.

‘Change of plans, mind if we do it at Eight or Seven?’

Sonic nodded and replied in agreement while making his way over back to the apartment in hopes of finishing the computer work for him. He was gonna work hard to pull back the stress from him.

——————————————

Back at the Apartment complex, Infinite sat on the bed with his hands on the sides of his head. ‘Dammit…Why does this always happen to me?’ He clenched his jaw tighter, scowling at the stress he was enduring, he was planning on going back to his family before realizing he may be at risk of getting caught for embezzling the money he had stolen from Shadow when he first met him, at the same business, at the same time when he stole the funds from him to get back at him. 

All those years ago.

As he tried to get it together, he hatched a plan. All he’d need to do was just put his book of expenses in Shadow’s room and report it to the police, then he’d be clear and finally get back at him for stealing what he once wanted. To be the one on the hierarchy of popularity. He exited his apartment and went over next door, grabbed the doorknob, and tried to open it. However, it couldn't open.

‘Won’t they know that it was me with the security cameras?’

He needed to rethink his plan. Besides, He didn't get into a feud with him, it was that Red Echidna. It’d be useless if he attacked someone else who got on his nerves. “Shit! What should I do…”

Footsteps on the stairs made him snap out of his thinking, he turned his head and saw Sonic, with the strap of his laptop bag on his shoulder. “Infinite?”

“Wh—What are you doing here, Sonic? You startled me!” The Jackal immediately dropped the expense card book on the ground.

“Heh, sorry! I just got back to do something for Knuckles!” The Hedgehog put his hands on the back of his head. “Uhm, Speaking of which, you are in the way of our apartment. What were you doing?”

Sonic bends over, grabs the bankbook, and looks at it up close before handing it to him. “A bankbook, huh? Is this yours by any chance?”

Infinite, realizing Sonic must’ve seen it made him panic inside of his head before he gained his composure back and stared at him. “You must’ve gotten it wrong, I must explain this to you but, Knuckles is embezzling in a business I’m in.”

Appalled by this accusation, Sonic raised an eyebrow. “Knuckles…Embezzling money?”

“I found the evidence that you were just holding,” Infinite continued, opening it and putting his finger on a page. “Here it is, this piece of information was one of the anonymous callers telling me about. Which is what the company needs to go on a funded business trip.”

“No way! I don't believe you!”

“Hmph, refusing to believe me is a sin, Hog. Never explain this to anyone and I’ll deal with this—!”

“Then give me more details.”

Infinite raised an eyebrow, folding his arms before turning his head and seeing a door opening nearby. His heart was pounding heavily, before lending a hand to the blue fur. “Then, perhaps, let’s discuss this inside.”

——————————————

Once they went inside the apartment, Infinite scanned around the room for any more evidence that he could use against Knuckles or Shadow but only found rather mundane items such as photos of the past, magazines, and the laptop Sonic carried earlier. He sighed in relief, it was a smart decision to move somewhere secluded, despite it being Sonic’s apartment.

Once the blue fur got settled, he changed into his casual clothes. A baggy brown tank top with a pair of shorter black shorts, he folded his arms and sat down on the edge of the bed.

But it’ll be hard to convince him.

“So, Knuckles embezzling money? I don't believe he’d ever do that!” Sonic folded his arms. “Tell me more, Finite.”

“Believe what you may prefer, but the book is unforgettable evidence,” Infinite scoffed, he sat down on the bed before getting up. “That's all for this question-and-answer talk.”

“Oh? But if it were the case, what would happen to him?”

“Fired and arrested, naturally, but if it were dire then he’d get blacklisted.”

Sonic raised an eyebrow in suspicion, his arms folded before they went down, and put his hand on his hip. “Are you by any chance, framing him?”

“Whatever the case, it's all up to the boss now.” Infinite turned around and began walking off. “Well, in due time, just get ready to—!”

Just as he got to the door, Infinite felt his arm being grabbed by Sonic. He turned his head and noticed his pleading eyes and his almost sad expression. “Wait, please, maybe Knuckles has a good reason behind it, maybe it’s not him! Just wait a bit longer before reporting it…”

Infinite raised a brow before a smirk formed, he realized that the hedgehog didn't doubt him but rather wanted to help Knuckles. After locking the door, he walked closer to him, his fist unraveling as he put it on Sonic’s shoulder before moving it down to his chest, squishing it.

Let's see how far he’ll go to protect him.

The hedgehog immediately smacks Jackal’s hand away from his body. “Wh-What are you doing!?”

“Come now, Sonic, you think having an attitude with me will fix anything? Perhaps I’ll tell the cops that I didn't find anything or I may reconsider my choices, it's all in your hands,” Infinite leaned in, his hand grabbing Sonic’s shoulder while his other hand touched his chest, messing up his baggy brown tank top. “I may even do something about the missing funds as well…hm?”

Sonic hesitated to go along with this plan until he clenched his black shorts with a frustrated expression. Infinite smiled sinisterly, letting his touch on the hedgehog’s chest go back into a groping as his grip on the shoulder fastened. Hearing him try not to give in as quickly as he expected just satisfied the Jackal more. “Just as I expect from you, so quick on the uptake.”

He gripped the hem of the tank top, making Sonic feel the sharp claws on his fur. “Is he that precious to you?”

“Whatever, just get it over with, will you?” Sonic scowled, his teeth clenched.

“Don’t rush me.” He barked, moving the hem of the shirt up and tossing it aside, causing the hedgehog to tremble slightly. “Let me have my time to enjoy this.” he scowled, staring at his chest before leaning in, having his claws on his chest, letting it touch and hover over his scars. With a grin, the jackal began licking and sucking on the hedgehog's nipples.

“You disgust me, Finite.” Sonic let out a shaky breath, his whines and yelps only made the Jackal continue further. Sonic grimaces at him, closing his eyes while hearing and feeling his chest being sucked on made him feel weird. ‘This horn dog…is the worst!’

Infinite chuckled, pressing his finger down on the hedgehog’s nipple. “Hm, your chest got stiff, are you enjoying this?”

“B-Buzz off, Finite, this is just a normal response!”

“Hmph, you stubborn brat, sit on the edge of the bed and spread your legs.”

Sonic flustered at the request, parted them briefly, only revealing bits of his crotch. Infinite raised an eyebrow, unsatisfied. “Huh? That's it? Spread it wider, hog.”

The Blue Fur hesitated to continue as the embarrassment was settling in him before Infinite’s hands reached down to his inner thighs and spread them further apart, causing his body to jolt out of fear. Sonic pressed his hand against Infinite’s arm. “No, don’t do th-that just yet—!”

Infinite snapped back. “That's no way to talk to me!”

Before the hedgehog could finish, the Jackal flicked his finger at the hedgehog’s crotch, causing him to shake as his body twitched from the abrupt pleasure while letting out a yelp. Throwing his head back as he felt his pussy swelling a bit. Uncertainty grew much bigger, he was always insecure about having his first time like this, he always thought he was unfinished considering he wanted to save up for the bottom surgery.

“My my, do you understand your position,” Infinite raised an eyebrow. “How long will you lie there?”

Sonic trembled briefly before he rolled onto his side, his body still twitching, not realizing that his shorts were moved down his legs. “Wait a se—Ahn!”

The Jackal tugged on the crotch of the hedgehog’s underwear, causing the hedgehog to squeak with a yelp, he turned his head and noticed Infinite was staring at his stuffy Pussy and his hole. “D…Don’t look..!”

“Why should I wait? I only touched you a little and you're already sticky. What a pathetic pervert,” Infinite teased, leaning in as his hands pressed against Sonic’s entrance and spread apart his pussy, causing him to cover his mouth. “Considering how quickly you got wet, it appears that you have some experience, yet you still have your hymen. Do your friends get to see your beauty? Do you just work and masturbate all the time?”

Leaving no room for the blue fur to respond, the Jackal grips Sonic by his ass as he begins to insert a finger inside of his pussy. Hearing the hedgehog softly whining and moaning quietly, pleased Infinite as he leaned in. “How is it feeling? Isn’t it better than when you do it yourself?”

Sonic, while quietly moaning as tears pricked at the corner of his eyes, had his body twitching as he tried to keep his composure. “This doesn't feel good at all—Hee!?”

He was interrupted once again by Infinite leaned over as he was licking and sucking on Sonic’s pussy, his hands squeezing his ass, his tongue inserting inside of him, rubbing against the spot that continued to make the Hedgehog moan loudly. “Don’t suck it—!”

He pulled his tongue out of him, leaving the hedgehog there to twitch as he tried to catch his breath. Infinite smirked, thinking that his idea was worth it. “Your pussy seems to not have an attitude, does it? Did you like it when I suck on the skin covering your clit?”

No response. ‘Perfect, just what I wanted.’

“Your reaction was just what I expected from a virgin, this was a good idea after all.” Infinite unzipped from his dark gray suit pants and let his cock swing out in front of Sonic once he opened his eyes, making him startled. “Now, it's your turn.”

The hedgehog covered his mouth before Infinite grabbed his hands and put them on the bed. “D-Disgusting! Don’t make me—!”

“Disgusting? If that's the case then why don't you clean it with your mouth?” Infinite teased, grabbing Sonic by his quills as he aimed his cock at his mouth. “Besides, sucking me off will—get me ready for the main event!” he shouted as he slammed his cock deep inside Sonic’s throat, thrusting inside of his mouth.

Sonic’s body twitched with every thrust, feeling his pussy dripping with squirt as he tried to stay calm but felt like he was going to choke on the Jackal’s cock, making his eyes water even more. “Come on, hedgehog, use a lot of spit to clean me off. And don't even bother to bite it.”

Infinite glared down, his eyes matched the hedgehog’s, even with his pleading eyes, he continued going roughly with him to just humiliate him. Hearing him gagged made it much more pleasurable for him. “Gagging like a little rodent, like you with my cock is pathetic!”

With a smirk, Infinite pulled out of Sonic’s mouth with a wet popping noise, watching him coughing out the saliva made the jackal grab him by his arm and pull him to the couch where he shoved him down, making him get into a dog-like pose. “There is no time to rest, Hog.”

As Sonic tried to catch his breath, he felt him pressing his cock against his pussy, making him whine even more as his heart pounded harder in his chest, feeling Infinite leaning in and whispering. “I’m putting it in, Hog.”

The hedgehog feels his inside ripping as Infinite slowly pushes his cock inside of him before he slammed it inside of him fully, causing Sonic to moan loudly with a sharp cry, gripping the couch cushions. He could feel the blood dribbling down from his pussy. “This pain, above all other pains, is very special to you.” The Jackal teased. “You only experience it once, so be sure to cherish it.”

The blue fur ignored him, his whining and whimpering were all he could hear as he felt his pussy being pounded harshly as he leaned in and grip onto the hedgehog’s waist, scratching up his blue fur. Infinite glances up and sees Sonic looking behind him with tears rolling down his face. “Are you crying because you are used goods now? Hah! We’re only having fun together, are we, Sonic?”

Sonic wished he could shake his head and continue his confident attitude, but his body growing numb with every thrust Infinite made to just pound him harder. With every groan, the blue fur scowled with humiliation as he could feel his hot breath behind him, feeling it behind his neck. Even hearing his chuckle from observing him, made the hedgehog despise him even more. “Heheh…Sonic lost his virginity to his roommate’s enemy? Don’t you think it's good for you, since you’re so confident?”

Meanwhile, outside of the apartment, Tails walked up the stairs in search of his older brother, glancing around before noticing the door was unlocked and had a light on. “Huh? Is someone inside here, I figured Sonic was ready a few minutes ago!”

Tails opened the door further before glancing around. “Sonic! Are you home? Knuckles told me to come get you!”

“Knuckles is waiting for you in the car, the party got moved to the park, and Rouge chose it because of the fireworks!”

While Tails continues to get his older brother’s attention, Sonic is still on all fours in the closet as Infinite gripped his hips. The hedgehog tried to stay quiet while feeling sweat dripping off of his body and his body quivering, he would rather die than have his own younger brother find him like this. He closed his eyes as he quietly pleaded for him to not come over to the closet.

While Distracted, Infinite smirked as he spread Sonic once again, having his thumb rubbing his hole before shoving it inside of him. Which made the hedgehog shudder and covered his mouth, feeling his hole being violated while having Jackal’s cock still inside of him made him want to think that this was some nightmare he was in. He quietly whined before hearing Tails walking away and closing the door to give Sonic privacy. Infinite chuckled. “What a surprise the little runt gave me,”

“You started moaning while he was here. What would you do if he found you here?” he leaned in as he pulled out his thumb from Sonic’s hole. “Or did you want him to see your face while I played with your slutty hole?”

“Pull it out…” The blue fur pleaded quietly, his whines growing as Infinite continued thrusting inside his pussy despite his facial expression being stern. “Hmph, your reactions are quite different than before.”

“That's no—Oooh~!” The hedgehog gripped the floor as soon as Infinite smacked his ass. He felt his body shaking as the Jackal continued thrusting deeper inside of him. “Hah, what’s with that voice? Did I hit the mark, hm?”

“You’re wro—Aaah~!” Sonic was once again interrupted by getting his ass smacked harder again, his shaking body made his mind gradually fog up before with a few more smacks and with Infinite pulling out and slamming it deeper again. “You should be starting to feel good since your pathetic pussy’s getting used to it.”

Sonic’s eyes rolled in the back of his head as he felt his chest being teased by Infinite again before feeling his other hand rubbing his midriff. “Your womb’s descending here, can you tell?” he teased, his voice drenched in a growl. “Your body wants to get pregnant with my child.”

‘Pregnant? I-It’s a lie, right?’

“I’ll fill you full of cum like you want.” The Jackal scoffed as he pinched Sonic’s nipple and his other hand had his fingers grinding on his clit as he thrusted faster inside of him, letting his hip slap against Sonic’s ass. Which made the blue hedgehog realize he wasn’t joking.

“No, wait—!”

“Take it all, Hog!”

“You’re not serious!?”

“I’m cumming inside you!”

“No—!”

With enough thrusting, Infinite slammed deeper into him, his cock throbbing as he released so much of his cum while Sonic screamed out his moaning and his body twitching. Despite all, the Jackal was not satisfied just yet, he still had some cum left to dispose of. Sonic’s body was staggering as he whined. “No, wait, I don’t want a baby…Take it out.”

Infinite scowled as he grabbed the hedgehog’s waist, moving it left and right to get a great angle. “Don’t Move!” He barked as he slammed it inside Sonic again, which resulted in a louder moan as he squirted. The hedgehog whined as he pulled out of him, unknowingly out of fright, he felt a dribble of piss slowly flowing out of him.

‘Finally, I have gained my victory.’ 

Infinite chuckled to himself. “You’re happy to the point of pissing yourself?”

Sonic gasped to catch his breath, his body trembling and twitching. “I don’t want to…get pregnant.”

While cum was still flowing out of the hedgehog, Infinite grabbed his leg harshly, causing Sonic to jump from the sudden grasp. “Come on! Since your body is such a distraction, I’m not satisfied, so we’ll do it three more times.”

After a few hours passed, Infinite had his phone out and took a few pictures of the tired and messy hedgehog that was on the bed with a satisfied smile, observing the amount of cum, sweat, and hickeys he had given him. It was the perfect revenge he could ever give. “It's been a while since I came until nothing was left. After this, hog, you’ll certainly get pregnant if you don’t take a pill.”

After cleaning himself up and redressing himself, Infinite leaned in and grabbed Sonic by his quills. Looking at his teary eyes as tears slowly poured down his face, another grin plastered on his face. “Sonic, as promised, I’ll keep quiet about Knuckles. But from tomorrow on, you’ll do exactly as I say.”

“No matter what it is.”

Sonic sighed as he got up after Infinite let go of his quills, he walked around and went into the bathroom to clean and redress himself. Afterward, went into the cabinet, took the pill, and left the bathroom to only be met with the face of Infinite once again. “Tell me, Sonic, how does it feel to have your first time with your roommate’s enemy?”

The hedgehog scowled before flinching as soon as Infinite pinned him against the wall. “Don’t forget, I know Knuckles embezzled six million dollars. Not only I’ll defend him, but I’ll go to that same party that your pathetic friends held. So,” Infinite grabbed Sonic by his chin and raised it for him to look up at him. “Behave well for me, Hog.”
