This is my first MCU fic. I'm a huge slut for Starker, so here goes!

Warnings: Rape/non-con

1095 Days

Day 1

Prison was a pretty boring place to be, in general. There were occasional fights, and every now and then something interesting would happen, but most of the time things were repetitive and monotonous. Most days were the exact same as the days previous. The same routines, the same food, the same faces.

Tony Stark was serving a life sentence for first-degree murder. He'd killed a man when he was in his late twenties, and now in his mid-forties he was accustomed to prison life. He knew the ins and outs, and he knew the people. There were some prisoners who were in it for the long run like himself, but most people came and went. Some people even left and ended up back in prison again shortly after.

It had taken a couple of years, but Tony had established himself as a respectable member of the prison community. It was rare for another prisoner to pick a fight with him. And as for the new meat, Tony always got dibs. He wasn't ashamed of his affinity for young, fresh-faced men, and if any other prisoner had something against his affinity, he'd put them firmly in their place. Many a prisoner had been sent to the infirmary for talking shit about Tony's sexual escapades with the freshman prisoners – as they were called.

But for the most part, Tony found prison life dull. Before prison, he'd been a celebrated scientist in his field. He was smart – smarter than most people, in fact, and he never failed to mention that fact. He'd had his whole successful career ahead of him, with Nobel Prizes and awards, and maybe even a future wife and kids on the table. But he'd thrown it away in an instant with the pulling of a trigger, and so he was here.

His cell was exactly the same as every other cell – a bunk-bed, a metal toilet and sink, and a rickety table with a chair to sit on. The cell door was a row of bars with a lock on the right-hand side. There was no privacy, and that was to be expected. This was a high-security prison, after all. The only privacy one had was when a prisoner was having a… well… intimate moment with another prisoner. It had become common for prisoners to hang bedsheets up across their cell doors when having sex, just for that extra bit of privacy. But other than that, everything was on full view.

Tony was alone in his cell at the moment. His previous cell-mate, Steve, had been transferred to another cell due to the numerous fights that had broken out between them. The two had clashed, and both had ended up in the infirmary multiple times. Tony had got to keep the cell, as it had been his cell for most of his years at the prison. Steve had been relocated to another cellblock, much to Tony's relief. He was quite happy to be alone with his thoughts. Sharing a cell could be tiresome, but it all depended on who the other person was.

When the C.O appeared in front of Tony's cell door, Tony pretty much knew he'd be getting a new cell-mate. It was overdue. He just hoped it wouldn't be another Steve.

"Stark," the C.O said briskly, staring in through the bars at Tony. Tony stood up and raised his eyebrows. The C.O spoke again. "You've got a new cellie."

Tony waited silently. The C.O unlocked the door to his cell, slid it open and then turned to face someone who was out of Tony's sight. "Parker, this is your cell," he said. Just then, a young man came into Tony's line of sight. He hesitantly stepped inside the cell, and the C.O gave him a light shove so that he was inside the cell enough that he could lock the door. Tony glanced up at the C.O, who was giving him an apprehensive look. "Play nice, Stark," he said in a knowing tone. Tony smiled sweetly at the C.O without a word, as he disappeared, leaving him alone with his new cell-mate.

The young man – or boy, as Tony liked to think of him – didn't seem to want to look at Tony, but Tony simply couldn't stop looking at him. He was very young, very sexy, and so innocent-looking that Tony couldn't possibly imagine how he had ended up in prison for any crime other than being too fucking hot for his own good. Tony subtly licked his lips and then held out a hand for the boy to shake. "Tony Stark," he introduced himself calmly.

The boy looked down at Tony's hand as though it was a dangerous animal that would attack him at any moment. His gaze rose slowly to meet Tony's. He looked fearful, and Tony found it somehow alluring. The boy's hand came up to shake Tony's, and Tony could feel how sweaty his palm was. "I- I'm Peter. Um, Peter Parker," he mumbled in barely a whisper, letting go of Tony's hand almost immediately after shaking it.

"You nervous, Parker?" Tony asked, leaning back against the bunk and smirking at Peter with a mischievous glint in his eyes.

"N-Nervous?" Peter asked, looking extremely uncomfortable. "No."

Tony stared at Peter with a ravenous look in his eye. He wanted him. And Tony always got what he wanted. Guys like Peter were very rare, but they were always Tony's favourite play-things. They were pure, they were clean, they were submissive. They were so easily manipulated.

"You should be nervous," Tony said, staying in the same position. He smirked more when he noticed Peter taking an anxious step backwards towards the wall of the cell.

"Will you… will I… which bunk shall I-"

"-What did such a pretty boy like yourself do to get yourself locked up?" Tony interrupted, loving the way Peter's face reddened at his words.

"I'm… sorry?" Peter asked.

"What crime did you commit? You might look like a good little boy, but you must have done something wrong to get in here."

He watched as Peter looked down at his hands, seemingly ashamed of himself. "I- well, I… I stole some stuff. I'm not proud of myself. It was a… a desperate mistake."

Tony raised his eyebrows. Of course. "A thief, huh?" he said. Thieves were always the naughtiest, and they always tended be a good fuck. Tony was impressed so far.

Peter nodded, blushing more. "Yeah, I- I guess so."

"Don't you wanna ask what I did?" Tony asked, standing up straight again and taking a step towards Peter.

"What did you do?" Peter asked quietly. He attempted to step back, but there was nowhere to step back to. His back was pressed against the cold wall of the cell.

Tony continued stepping forward. He was now inches away from Peter, and he couldn't stop staring at those soft, lightly-parted pink lips…

He cleared his throat and leaned in towards Peter's ear. "I killed a man," Tony whispered, almost seductively. He felt the boy shudder at his words, and he couldn't help but smile. "But don't worry, baby," he added, still in a whisper, "You're too pretty to kill."

Tony leaned back slightly, giving Peter a little bit of room to breathe. He brought his hand up to brush his thumb gently across Peter's rosy cheek, caressing his smooth skin and staring intently into his deep brown eyes. Peter seemed to be frozen in place. He was trembling, and his eyes glistened with tears that were threatening to escape. Tony reached his other hand up to the top of the cell door, releasing a large white bedsheet. The sheet dropped, covering the bars of the cell to give them both some privacy.

"Do you know what it means when we cover the cell door with a sheet?" Tony asked, rubbing his thumb over Peter's cheek again.

"I- I don't-"

"-It means we're going to make love," Tony murmured, using his free hand to grab Peter by the waist and pull him closer. Tony breathed hotly against Peter's ear and he was pretty sure that Peter was now crying. "I'm going to make love to you, Parker."

"Please don't," Peter managed to say, his voice sounding desperate and strained.

Tony tutted, regarding Peter with a disappointed look in his eyes. "You don't want that, hm?" he asked softly, leaning in again and biting gently on Peter's ear. He heard a small whimper come from Peter's trembling lips.

"No, I- I don't-"

"That's okay, sweetheart, we won't do that," Tony said, letting go of him. Peter looked surprised, but mostly relieved. Tony watched the boy wipe away his tears, and he smiled down at him. Peter was truly beautiful. Tony didn't think he'd ever seen anyone so beautiful in his life. He allowed himself a minute to appreciate Peter's beauty, before he grabbed him again, roughly.

"What're you doing?" Peter gasped, trying to break free from Tony's grasp but failing completely. Tony was a lot stronger.

"I'm going to fuck you," Tony growled, turning Peter around and throwing him down onto the bottom bunk with much more force than what was necessary. He needed to show Peter who was boss. "You don't want to make love. Sure, that hurts my feelings, but that's alright. If you don't want to make love, you're getting fucked. And you're going to enjoy it for me, aren't you?"

"Please," Peter sobbed. It was almost heart-breaking for Tony to hear the boy beg so sweetly for him not to do it, but he knew that there wasn't a choice. He had to do it. He had to make Peter his. He had to make all of the other prisoners know that Peter was his. He had to make Peter know that he belonged to Tony now. He was Tony's property, and Tony owned him completely.

Tony climbed on top of him, pushing his whole weight against Peter's small body. "You belong to me now, alright? Shhhh, it's okay. I won't hurt you. Not unless you resist." He placed his hand over Peter's mouth, silencing him. He could feel Peter's tears soaking into his skin, and he felt how the younger man sobbed into his hand. "That's a good boy. Shhhh."

They stayed in that position for a moment, Tony giving Peter a chance to calm down and come to terms with what was going to happen. After a minute, Tony stood up. Peter stayed, lying face-down on Tony's bunk, quiet sobs making the bed shake a little.

"Get up," Tony ordered. Peter didn't respond, so Tony grabbed him by the back of his prison uniform and pulled him up. Peter narrowly missed whacking his head on the top bunk. Tony loved how light the boy was – so easy to control. "Are you deaf?"

"Please," Peter said quietly. "You… you don't have to do this."

Tony ignored him, turning him around so that they were facing one another, and ripped his uniform open from the front, letting it fall to the floor. Peter scrambled to try and pick it up, but Tony shoved him back onto the bed again and shook his head. "Not happening."

"T-Tony-"

"-It's Mr Stark to you," Tony growled. "Or Sir."

"Sir, please," Peter begged, trying to get back up, but finding himself being pushed back. Tony quickly pulled his own clothes off and straddled the younger man. He glanced down to pull off Peter's boxers and smirked.

"Nice Star Wars boxers," he commented. "How old are you, anyway?"

"N-Nineteen," Peter replied in an obvious attempt to sound confident, but his nervous stutter gave it away.

Nineteen, Tony thought, licking his lips. Perfect.

"I like them young," Tony said, grabbing Peter's boxers and pulling them off with one hand, while his other hand held him down. "You youngsters are able to handle more, you know. I can be rough with you and you'll be able to take it, won't you?"

"I'm… I…" Peter looked utterly destroyed already. "I'm a- a virgin."

Tony's face lit up at this revelation. Nineteen years old, a thief and a virgin. It was almost as good as a C.O coming into his cell right now and announcing that he was free to leave.

"Turn over," Tony said. "I want to see your pretty little ass."

Peter stared up at him, looking terrified. "No," he said, defiantly.

"No?"

"I won't."

Tony shrugged and got up, turning Peter over easily.

"Please stop," Peter cried, struggling against Tony's hold, trying to get up. Tony held him down, his fingers digging into Peter's shoulders.

"You're being a bad boy, aren't you?" Tony said, leaning over him and brushing his hard cock against Peter's ass. "Do you know what happens to bad boys?"

"I-"

"-They get treated like dirty little sluts," Tony murmured against Peter's ear. He lowered his head and bit Peter's neck softly, sucking and nipping at the skin, trying to leave his mark. He wanted Peter to have to walk around tomorrow with bruises all over him – signs that he was the property of Tony Stark.

Peter was still struggling, but Tony was now completely on top of him, and his slight build was no match against Tony's muscular build. Tony bit a little too hard on Peter's neck, drawing blood and making Peter gasp.

"Are you my dirty little slut now, Parker?" Tony asked. He ran his tongue over Peter's sensitive skin, tasting his blood.

"No," Peter said in barely a whisper, his voice muffled by the mattress. He had his face pressed into it, and there was a damp patch from where he'd been crying.

Tony rubbed his cock harder against Peter and used his hand to pin Peter's hands above his head. "You are, aren't you?"

"Please-"

"You're a feisty one, and I love that," Tony said in a low voice. "But either you're my dirty little slut or I'll fucking murder you. Your choice. We both know I'm capable."

He heard Peter gasp, and he felt him tremble beneath him.

"So, what are you, Parker?"

"I- I'm… your… I'm your dirty little slut," Peter mumbled through tears.

"Good boy," Tony said with a smile, still rubbing himself against Peter's ass. "That's such a good boy. Now I'm going to fuck you, and I want you to take it like the good little slut you are. Can you do that for me?"

Peter didn't say a word, but Tony saw him nod.

"I didn't hear you, slut," Tony said coldly.

"Y-yes," Peter whispered.

"Yes Sir," Tony corrected. "Say it."

He watched as Peter closed his eyes. "Yes. Sir," he said quietly, and Tony knew Peter's heart wasn't in it, but it still turned him on nonetheless. He would condition this boy to love it over time. He could have so much fun with this one.

Because Peter had resisted so much, Tony refused to give him the liberty of preparation. He'd get fucked, raw. And since Tony knew that this was Peter's first time, he knew it wouldn't be pleasant for the younger man. Maybe that would teach him a lesson about being obedient in the future.

Without so much as a warning, Tony lined himself up with Peter's tight hole and forced himself inside. It was tough, and he had to push hard. Peter was crying out in pain, and that only urged Tony on more. He kept pushing. It was so tight, and Tony loved it.

"Please stop," Peter begged, between pained noises. "Please, it hurts."

"Shut the fuck up," Tony grunted, thrusting deep inside him. "Take it, you fucking slut."

Peter had decided on a new approach. He started screaming "help!" in some hope of a C.O taking pity on him and helping him out, but Tony was fully aware of how corrupt the staff were in this place. Tony still had a lot of people in high places on the outside, and they had chequebooks with the C.O's names in them. Nobody was coming to Peter's rescue.

Tony fucked Peter as hard as he could, using the top bunk as something to hold onto, to give him enough power to plunge into Peter's tight ass with all the strength he had. Peter was a mess beneath him. He was still calling for help, but his cries had become weak, broken, hopeless…

"Nobody's helping you," Tony muttered between thrusts. "Nobody cares."

Peter had stopped resisting at this point. His body had become slack, just allowing Tony to use him. He'd given up. But Tony could still hear his muffled sobs.

"Do you want me to stop?" Tony asked.

"Yes," Peter said.

"Yes?"

There was a pause, and then Peter spoke. "Yes Sir."

"Mmmm, good boy," Tony moaned, thrusting harder, close to orgasm. "If you want me to stop, you need to do one thing for me, baby."

"Anything, Sir," Peter whispered, sounding drained. Tony loved what he'd turned the boy into – a whimpering, submissive mess.

"Fuck," Tony breathed, getting lost in the moment as he slammed into Peter. "Mmm, I need you to tell me what you are. Can you do that for me, sweetheart?"

He could still hear Peter crying. "Yeah, I- I can do that."

Tony couldn't last much longer. It felt too fucking good. "Go on," he murmured, keeping up the same pace.

He felt Peter wince beneath him. "I'm… I… I'm your s-slut, Sir," Peter said with a shaky voice.

"Fuck yeah, you are," Tony said, pulling out quickly and stroking his cock. He grabbed Peter around the waist, pulling him off the bed and turning him around to face him. He shoved him to the floor of the cell onto his knees. "Suck my dick."

Peter's tear-stained eyes stared up at him for a moment with a pleading look, but Tony grabbed his head and forced his cock into Peter's mouth. "Look at you, tasting your own ass," Tony said, holding Peter's head in place and fucking his mouth roughly. Peter was gagging and his eyes watered, and Tony was so close. "You love tasting yourself, don't you, slut?"

Peter nodded, choking on Tony's cock. Tony smirked and pushed himself further down Peter's throat. "I didn't hear you," he teased.

Peter tried to speak, but he only gagged louder. Tony let go of his head, and Peter pulled back, gasping for air, with a string of saliva running down his chin. His eyes were streaming and his face was read. Tony only gave him a second to recover before shoving his cock back into his mouth.

"I'm gonna cum in your mouth," Tony said. "You're gonna swallow every last drop, aren't you, baby?"

Peter tried speaking again, and he gagged again. Tony was done; he fucked Peter's mouth hard, moaning loudly as he came, hot white ropes of cum spilling down Peter's throat. He kept fucking Peter's mouth until he was too sensitive to thrust anymore, and then he pulled his cock out. He brought his hand to Peter's mouth, forcing his mouth shut.

"Swallow it."

Peter swallowed. Tony smiled. He'd trained him well in the short amount of time they'd been together.

"Such a good boy," Tony crooned, leaning down and planting a kiss on Peter's lips. "See, that wasn't so hard, was it?"

Peter blinked and wiped away his tears. He was still naked and on his knees. He only shook his head, looking broken.

"What was your name again?" Tony asked, fully aware of what his name was.

"P-Peter-"

"-Wrong," Tony said loudly. "Slut. Your new name is Slut. You'll go by that name from now on. You got it?"

Peter nodded, closing his eyes.

"Good. You can have the top bunk."

Peter shakily got to his feet and grabbed his clothes. Tony watched as he got dressed and climbed into the top bunk of the bed. After a few moments, Tony got dressed too and then removed the sheet from the cell door. He climbed into the bottom bunk and smirked to himself.

"Hey, Slut?" he said, staring above him as though he could actually see Peter through the mattress.

"Y-yes?"

He grinned. Good – he was answering to his new name. "I had fun today."

Silence.

"We'll do it again tomorrow," Tony continued, even though Peter hadn't replied. "And the day after, and the day after… say, how long is your sentence?"

There was a pause, and the Peter spoke in a quiet voice. "Three years," he said.

"Three years," Tony repeated. "1095 days of getting fucked by me. I hope you're up for it."

The only response Tony got was a stifled sob. Tony couldn't be happier. Prison wouldn't be so boring after all – well, at least not for the next three years, anyway.
