Summary:

Alpha SIM Tony wants Omega Peter for himself. But when the boy resists his advances, he'll use whatever means necessary to bind the Omega to him.

Notes:

First, thank you to TheMadStarker for being my wonderful beta. Also fair warning now, Tony drugs and uses Peter repeatedly, so if that's not your thing, please close the tab now. Mind the tags.

Work Text:

Since becoming Superior, Tony had not wanted for much. It was easy to put on a mask, smile at the right time and no one even noticed his eyes went from brown to blue or that he'd practically stopped aging. Nor did the few people he still cared about notice when he spiked their food with a watered down extremis at his birthday party. After Obie, and Killian, after New York, Tony wasn't willing to take chances any more. 

And it turned out to be a very good thing after something tried to crash his systems and kill JARVIS. With his link up, he'd been able to initiate a complete shutdown of everything, isolating the threat quickly and with prejudice. The alpha played it off as a hardware failure, working quickly to restore everything even as he tightened his security around his files. 

Time passed and Tony continued to shore up his power behind the scenes, schmoozing the right politicians, investing in everything from green energy to education, all the while building his reputation with the public. It was funny how no one noticed that it was only his image he was building, not the Avengers or even SI. He stood back as Rogers and the others drove themselves to ruin in the public opinion until he was the only hero worthy of being venerated with War Machine and the Falcon at his side. And oh had stealing Wilson from Rogers been the feather in his cap. 

Now, he stood at the pinnacle of success with everything he wanted. Except for one thing. 

 

Peter Parker.

 

The little omega had originally popped up on his radar years ago when he had started his Spider-man gig. He had been genuine enough that Tony had sponsored him discreetly, providing a new suite with an AI, ostensibly to help the pup stay out of trouble, but also to monitor him in case he started to stray from the path like so many heroes before him. And yet, as the years passed and the boy finished high school, he never strayed. Tony updated the suit on occasion, and repaired it when the AI deemed it necessary, but otherwise, he simply stood back.

Tony offered him a full ride to a school of his choice as a reward for his good work. Peter tried to turn him down but Tony insisted and in the end, he paid for Peter to attend Columbia. It was the first time in a long time that anyone had even tried to tell Tony no, and it intrigued him. 

Unable to stay away, Tony started trying to court the Omega, only to be rebuffed constantly. It would have been insulting if he hadn’t realized that Peter was so shy and not used to Tony’s lavish lifestyle. The alpha changed tactics and started inviting Peter for lab time. Still, the Omega seemed to hold back from the Alpha and that wouldn’t do at all.

So Tony started the next phase of his plan. Omegas were very susceptible to bonding through exposure to Alpha semen, and Tony had synthesized a harmless tranquilizer that he slipped into Peter’s drink when they were working late one night.

“You ok, Pete?” Tony asked, watching as the omega’s eyes drifted closed, only to blink open, then start drifting again. 

“Guess I’m just tired, Mr. Stark,” Peter yawned. 

“Well, the guest room is always open,” Tony said, doing his best to appear concerned. “I don’t want you trying to swing back to your dorm when you’re this tired but I’m sure I can wake Happy up if you don’t want to stay.”

“No, that’s ok, sir,” Peter was quick to assure him. “The guest room is fine.”

As he escorted Peter up to his penthouse, Tony privately congratulated himself on having had the forethought to offer the room from the start so it wasn’t suspicious to the omega at all. 

Tony let the boy get settled, changing into comfortable clothes while waiting for JARVIS to alert him when Peter’s vitals evened out to sleep. Then he slipped into the guest room and closed the door behind him.

“There’s my princess,” Tony murmured, appreciating the view in front of him. Peter lay spread on the bed, having had only enough energy to strip down to his briefs before he passed out on top of the blankets. His creamy skin was flawless and his body was sculpted to perfection thanks to the omega’s special genetics. 

Tony stalked closer, letting his fingers brush gently along Peter’s legs before stopping at the briefs. He debated removing them but for today’s plan, it was best to keep things minimal. Instead, he gently re-positioned Peter on his back, then pulled his cock out, bringing himself to hardness quickly. He imagined fucking the omega in all of his holes, stuffing him full until he’s cum drunk and unable to think of anything but Tony. 

It didn’t take long for him to empty himself over the omega’s chest. An endosym tentacle formed, scooping up a bit of the cum. Tony gently opened Peter’s mouth, feeding the cum coated strand down his throat while stimulating the outside to ensure it was swallowed. He scooped up more and fed that to Peter as well, his cock thickening again just from the visual. 

Tony took his cock in one hand and continued slowly scooping cum to feed to his pretty omega. When he came again, he made sure to add it to the remnants on Peter’s stomach. Then he moved down the bed, running his hands gently over the boy’s briefs. Carefully, he lifted the band away from the boy’s cocklette, though he didn’t remove them. 

A strand scooped through the fresh cum and snaked down past the little cocklette and into the omega’s vagina. He was careful not to insert it too deeply, and made sure it was rubbed into the warm wet heat. Another scoop was rubbed in before Tony shifted to stuffing Peter’s ass instead. He threaded a nanite tube deep inside that he fed the remaining cum into. Once it was done, he retracted the endosym, swiping it over Peter’s stomach to remove any traces that were left. Then he rolled Peter back onto his stomach and grabbed a blanket from the foot of a bed and draped it over the omega. 


The next morning, Tony saw Peter off, and the omega didn’t act like anything was wrong so Tony considered it a success and started planning his next night. He couldn’t do it every time the omega was over, so he waited another week and a half before Peter stayed late again. Tony was quick to offer a drink and for Peter to stay so they could finish the project they were tackling.

The boy happily agreed, and soon, Tony was ushering him up to bed once more. As soon as the omega was asleep, Tony was back in the guest room. Again Peter was only in his briefs, and Tony couldn’t help but grab a handful of the omega’s firm ass. Then he rolled him over and climbed on top, though he was careful not to put his weight on the omega. He pulled his cock out and dragged the head over the omega’s chest, smearing precum along the whole length of it. 

Tony bit back a moan, wishing he could do more, like shove his cock down the omega’s throat or even fuck his thighs, but he knew he’d have to be patient for that. Instead, he quickly finished himself and started feeding his omega.


It took another three weeks of weekly marking for Tony to notice a change in Peter. The boy went from visiting two- three times per week to nearly every day, and when he was there, he stood closer to the alpha, taking conspicuous inhales around him. 

Tony hid his smile and didn't say anything, though he always left space for Peter and focused on emitting a soothing scent. When Friday finally arrived, Tony offered the guest room and Peter immediately accepted.

Tony felt the anticipation thrumming through him as he stepped into the guest room. This time he carefully stripped the Omega and removed his own pants as well. Then he positioned Peter on his stomach with his hips on a pillow, ass up in the air. As Tony knelt behind him, he imagined how Peter would whimper and whine for his alpha, begging for more when they finally mated. 

Tony gave himself a quick stroke before sliding down so he could taste his pretty omega. He started with gentle licks to the outside of the Omega's pussy, moaning softly at the sweet taste of slick. Peter might have been out but his body still reacted, more and more slick pouring out of his hole as Tony stimulated it. Tony lightly fingered the entrance, encouraging more to drop down Peter's thighs. When there was enough that it glistened in the soft light of the room, Tony pushed Peter's legs together, anchoring them with Endosym tendrils before shoving his cock between them. The alpha was careful not to hold too tightly, not to leave a mark as he fucked his omega with only slick to ease the way. When Tony came, he pulled back and aimed it directly at Peter's ass, letting it drip down to his wet hole before using more tendrils of nanites to stuff the cum into his princess. 

He used his nanites to clean up the extra again, and slid Peter’s underwear back up. Then he turned the omega over and moved up the bed so he could capture Peter’s lips with his own. Tony nibbled on the omega’s lips and kissed down his neck. 

“Soon, my love,” Tony whispered, placing one last kiss before slipping out of the room. 


Tony continued on, marking his omega regularly and encouraging Peter to visit as much as the boy wanted, never shying from whatever contact the omega initiated. They grew closer and while Tony knew it wouldn’t be much longer for them to start their relationship properly, he found that he couldn’t wait to claim at least a little bit more of his omega. So the next night Peter asked to stay, Tony offered him a drink and then waited for it to kick in. 

He stripped the boy and then arranged him so that his head was just at the edge of the bed. Tony slipped his still semi hard cock into the omega’s mouth, sighing at the warm wet feel. He gave tiny thrusts, careful not to cut off Peter’s air or go too deep. His cock continued to harden in the kid’s mouth, and precum mixed with saliva dripped down Peter’s face. Tony pulled his cock out and traced along Peter’s face with it, marking him as much as he dared. 

Then Tony rearranged Peter again, this time on his stomach with his shoulders down and hips up, presenting like the good omega he was. The alpha started with a single finger pressed into the boy's vagina, stilling as the boy whimpered beneath him. JARVIS confirmed that Peter was still sleeping so Tony continued stretching him, getting two and then three fingers in as the little omega moaned in his sleep. Slick dripped everywhere, and Tony used it to wet his cock as he rubbed the head along Peter's wet hole. 

Beneath him, Peter squirmed and whined like a bitch in heat, so Tony pinned him down with Endosym bands before returning to rutting along the outside of Peter's vagina. He pulled back slightly, grabbing his cock and smacking Peter's dangling cocklette with it, causing the omega to jerk and whimper. Then Tony slowly dragged the head of his cock from Peter's cocklette to his ass, making slow swipes up and down. Precum and slick mixed as he made an utter mess of his boy. Occasionally, he'd pause to tap his cock on the omega's wet hole or cocklette, watching with pleasure as the omega writhed for him. 

When it sounded like the omega was getting close, Tony completely covered his cocklette with an endosym case, then pushed just the tip of his cock into the omega's wet hole. He kept his thrusts shallow, but even that was enough to push Peter over the edge. Feeling his boy come around the tip of his cock had Tony emptying himself into Peter as well.

Nanites surged around Peter, cleaning him up, though a few dedicated strands were gathering up anything that escaped his pussy and burying it in his ass instead. Tony knew he should stop there but he wanted his princess stuffed full of him. With that in mind, he settled Peter on a pillow, his head supported but angled for easy access. Nanites trailed down and hooked Peter's mouth open, giving Tony even easier access. 

He knelt above the boy’s face and started stroking himself while sticking first one, then two fingers into Peter’s mouth. When he got close, he pulled his fingers out and eased the head of his cock in. Nanites massaged the omega’s throat, encouraging him to swallow as Tony filled his mouth. 

Satisfied that he had fully claimed his omega, Tony placed a gentle kiss on the boy’s forehead and arranged him back on his bed. 


Things seemed to build much faster after that. Peter was over at the tower nearly every day between classes, and he was always near Tony when he visited. Tony continued to encourage him, reiterating that he was always welcome, and his company was always appreciated. 

He kept his sessions with the omega to no more than once a week, though it was harder to resist the beautiful boy with how much he was around. His patience paid off though, when not even a month later Peter finally approached him.

The omega had been antsy all afternoon, and Tony was actually a bit concerned.

“Is everything alright, Pete?” 

“Yeah,” the omega practically squeaked. “Yes, it’s fine. I’m fine. There’s nothing.”

“You know you can talk to me about anything, right?” Tony said, moving closer to the boy. “I’m here for you, however you need me.”

Peter whimpered, his eyes dropping to the floor as the alpha stood in front of him. 

“Pete, please. Tell me what’s going on,” Tony encouraged. He didn’t like seeing his omega so on edge. 

“I- IthinkI’mattractedtoyouandwanttokissyou,” Peter said, the words tumbling out too fast to be properly understood.

“Can you try that again, baby?” Tony asked gently. “A little slower?”

“I, I like you, Mr. Stark. Like, I’m attracted to you,” Peter said quietly. “And I can’t stop thinking about kissing you.”

“Just kiss?” Tony couldn’t help but tease. “Because I adore you and would love to do more than that if you ever think you might want that too.”

Peter’s head shot up so fast that Tony was worried he was going to hurt himself. 

“Really?”

“I would never lie or joke about something like this, Peter,” Tony said seriously. “You are so amazing, I would be lucky to have you.”

“I’m the lucky one,” Peter said, leaning in shyly to place a kiss on Tony’s lips. Tony enjoyed the innocent kiss for a few moments before taking over and deepening it. Peter moaned, and Tony pulled back, taking in the look of pleasure on his face.

“So beautiful, baby,” Tony said. “You’re so fucking beautiful.”

Peter blushed an even brighter red, and mumbled a response that Tony couldn’t make out.

“Why don’t we go upstairs and we can explore a bit more if you want,” Tony suggested, offering his hand to Peter. “And if you’re not ready, we can watch a movie and just cuddle a little.”

Peter nodded, slipping his hand into Tony’s and letting the alpha lead him upstairs to the couches in the living room. As he sat, Tony pulled Peter down onto his lap gently, guiding the omega to put a leg on either side of Tony’s. 

“Hey, no need to be nervous,” Tony reassured the boy. “We’ll go at your pace.”

Peter nodded and immediately leaned in to start kissing Tony again. It didn’t take long for the kiss to deepen and for the omega to start rutting against him, the smell of slick and arousal filling the air. 

“Alpha,” Peter whined above him. “I need you.”

“Need me how, baby?” Tony asked, nipping at the boy’s neck as he ran his hands over the boy’s body. “What do you want?”

“You, need you,” Peter panted. 

The boy continued to squirm in his lap and Tony caught a different note to Peter’s scent.

“Fuck, baby, you’re going into heat.”

“Alpha.” The omega whined and whimpered, rubbing himself all over Tony. “Please, Alpha, take care of me.”

“Are you sure?” Tony tried to ask, but Peter didn’t respond, so the Alpha tried again, speaking firmer. “Omega, are you sure? Because I won’t be able to hold back. I will fuck you and I’ll bond you.”

Peter seemed to focus briefly at his tone, and his reply was clear.

“Yes, Mr. Stark, please, I’m sure. I want you to be there for my heat and bond me during it,” Peter said, panting as he ground against the alpha.

“Tony, baby. If you’re going to be my Omega, you should call me Tony.”

“Tony, please, fuck me,” Peter begged. Tony savored the boy’s voice and the desperate look in his eyes.

“Of course, sweetheart,” Tony said, picking the omega up and carrying him to the master bedroom. 



Peter splayed out in his bed, begging for him, was definitely the sexiest thing Tony had seen yet. While he had loved taking care of his omega before, this was so much better. 

“Tony, pleeeease,” Peter begged, squirming on the three fingers Tony had buried in the omega. 

Tony added a finger, stretching Peter’s hole carefully even as the boy cried for him to go faster. He had to make this perfect though. He had been waiting so long to finally claim his princess. 

Finally though, he deemed Peter ready. 

“Turn over, baby,” Tony said, nudging Peter until his shoulders and stomach were down while his ass was up, presenting his wet pussy.

The omega whimpered as Tony teased the edges of his hole, rubbing his cock in the slick before pushing himself in. 

“So tight, baby. Fuck, look at you, such a good omega,” Tony said. He pounded into Peter, egged on by the whimpers and cries of his soon to be mate. “Gonna fuck you so good and make you mine.”

He could already feel his knot forming, so Tony focused on getting as deep as he could, and then draped himself over Peter’s back so he could reach the omega’s mating gland. 

“Ready, princess?” Tony asked, licking at Peter’s neck. 

“Ye-es, Alpha,” Peter panted. “Mark me, alpha.”

Tony made a pleased noise, then started fucking into Peter harder. Pleasure burst through him as his knot caught and he marked his mate, biting until he tasted blood. Peter screamed beneath him, writhing as orgasm overtook the Omega as well. Tony shuddered as his knot was milked, his hips grinding against Peter. Finally though, he was able to roll them both onto their sides. Tony ran gentle hands along his boy’s body, soothing lingering trembles. 

“I love you, omega,” Tony whispered. “I’m so glad you’re finally mine.”

“Love you too,” Peter murmured, purring in his arms. “So happy you’re m’ alpha.”

“Rest, love,” Tony said, rumbling in response to the purr. “You’re going to need the energy.”



Tony looked down at his mate, the omega’s lips wrapped around his cock as Tony fucked his throat. Tears slipped from the boy’s eyes but his hard little cocklette made it clear how much he enjoyed his mouth being stuffed. It was their morning ritual of sorts. As soon as Peter woke, his lips would be on Tony’s cock, sucking and licking until the alpha would wake up. Then Tony would either flip them over and fuck into Peter’s throat, or he’d lay there comfortably and let his Omega take what he wanted. Once his belly was full of cum, Peter would get ready for work with Tony, and they’d head to the lab. 

Most days, Peter would sit on his cock as they worked, though sometimes Tony would have the omega warm his cock with his mouth instead, especially if Tony decided Peter needed a more relaxing day. After work, they’d head home, eat dinner, and then Tony would fuck him one last time, stuff his pussy and plugging it with nanites. His boy was insatiable but Tony didn’t care.

Everyone had been so happy for them when they had announced their mating. Peter matched Tony’s brilliance, and anyone with eyes could see the alpha doted on the omega. Of course, if they knew just how dependent on him and on his cum Peter was, some of them might protest, but Tony didn’t care. He had a system that kept his baby addicted to him but still able to function. After all, his brain was one of the things Tony loved about Peter, and he’d never take that from him. 

Peter was the hardest thing Tony had needed to work for since becoming Superior. The first one to have told him no in so long, and now, Peter was his too. Exactly as it should be.
