For the first time since joining the Avengers on missions, Peter found himself wishing the bad guy had dragged this out a bit more. Or, barring that, had the decency not to use biochemical weapons on superheroes while fighting inside the city limits. But no, a second-rate Dr. Doom wannabe decided he could replace magical tech with bio-weapons instead. And just like Doom’s bots, they were ineffective and prone to malfunction.
So now the whole team was being hustled towards decontamination showers at the Tower instead of heading back to the Compound for the debriefing.
“C’mon, Spiderling, move those webs,” Tony called, startling Peter from his fretting. “They’re not gonna let us eat until everyone is cleared.”
“I’m coming,” Peter called back, though he didn’t speed up his slow removal of his suit. Most of the team had already stripped and started their showers in the shared room, so if he could just hold off a bit longer, then he could get the room to himself.
Of course, he could have had the shower to himself if he’d just admitted to the team that he was an omega instead of a beta like he pretended to be. Assuming they didn’t ban him from superheroing, at least. At 19, he felt just as nervous about that secret getting out as he had at 14 when he started going out as Spider-Man.
“Pete, if you’re not in here in the next 30 seconds, I’m calling Cap back to carry you in,” Tony shouted as Peter heard the shower doors open and the alpha head in. Tony always took the longest because of the armor and under armor, so if he was done, then Peter was out of time.
He dropped his suit and underwear in the pile, taking a deep breath and praying that Tony was going to be too distracted to pay him much mind.
Tony was scrubbing down, only half listening to the others as they finished up. They threw a few jokes and taunts his way but he ignored it as he considered his protégé’s strange behavior. Peter had lagged behind the entire way to decontam, and even now, as the youngest hero slipped in, he practically hid in the corner to shower.
Of course, being the only beta in a group of alphas could cause some insecurity, Tony mused. He angled his body to help block Peter from the others even as he considered the best approach to assuring his protege that there was nothing to be ashamed of.
It could also be something entirely different, like an injury he was trying to hide. It wouldn’t be the first time his errant protege had tried to avoid treatment.
Regardless, clearly, discretion was the better part of valor here, so Tony continued to take his time while also doing his best to block Peter from view.
“We’re heading out,” Steve said, interrupting Tony’s thoughts. “Gotta get the debrief started if we’re going to be able to sleep tonight.”
“Yeah, no problem, Cap,” Tony said with an easy grin as he casually blocked Peter further. “Pete and I won’t be too long, but if the Pirate asks, he can talk to Friday or Karen for questions or instant replays of my awesomeness.”
The accompanying snorts and eye rolls made Tony grin. Mission achieved, and now, it was just Tony and Peter.
“How’s it coming over there, Pete?” Tony asked, finally turning his full attention to the younger man.
“A-alright, sir,” Peter replied without looking at Tony. “I’ll be done soon, so you don’t need to wait for me.”
“I don’t have to do anything,” Tony retorted with a scoff. “I thought I had taught you that already.”
As he spoke, he casually made his way over to the shower nearest to Peter.
“Ha, yeah, I know, sir,” Peter replied, still not looking toward Tony at all. “Just wanted to make sure you know that I’m fine and all.”
“Appreciate that, as I did consider you were hiding an injury,” Tony said lightly. He made a quick decision to address the issue head-on instead of tip-toeing around. “Especially given how jumpy you’re being right now.”
“No-not jumpy,” Peter was quick to reply. “Just a little wound up from battle still is all. I’m fine.”
Peter blindly reached towards the shower knobs, looking for something to do with his hands in his nervous state while he tried to avoid looking at the alpha near him. Unfortunately, he underestimated the amount of strength he was using, and his hand pushed straight through the wall instead, missing the knob by a few inches and burying it deep into the building materials.
“Oh fuck, shit, oh no.”
“Pete?”
Before Tony could come closer, Peter tried to brace his other hand in order to pull free, only for that hand to push through instead.
“Oh shit, oh shit, oh shit.”
Peter was nearly hyperventilating when he felt Tony’s hand on his neck, firm and warm.
“Easy, Pete, just breathe. You’re ok; this is no big deal and not even the first time the showers have gotten broken,” Tony said soothingly.
It took more than a few shuddering breaths for him to finally calm down, and when he did, he noticed the position he had landed himself in. The water was turned off, but Peter was stuck in a bent position, both hands locked in the wall and his ass sticking out.
“Oh fuck,” Peter swore, embarrassment causing him to flush all over.
“Hey, no getting riled up again,” Tony commanded, tightening his grip briefly on Peter’s neck and pulling a whine from the omega. Tony’s hand released then tightened again, causing Peter to whine in response once more, unable to stop it.
“Something you want to tell me now, Peter, before I confirm for myself?” Tony asked as his hand slid up and down Peter’s back soothingly. “Because I will be confirming one way or another, kid, and it’s better for you to tell me yourself.”
“I-I’m, you see, it’s just, sir, please.” Peter knew he was starting to babble nonsense, but he was exposed and terrified of what would happen when Tony knew.
“How about I make this a little easier?” Tony asked, his voice a deep rumble now. “Are you an omega, Peter?”
“Ye-yes,” Peter somehow choked out. “Yes, I’m sorry, I didn’t want to lie, but I wanted to be a superhero, and omegas aren’t superheroes. I was scared-”
“Hey, no, there’s nothing to be scared about,” Tony interrupted him, voice firm. “You being an omega doesn’t take away your skills or your powers.”
“You mean it?” Peter asked, wishing he could turn enough to see the alpha’s face. Tony seemed to sense that because he squatted down on Peter’s side so they were eye to eye.
“Absolutely, kid, I swear it to you,” Tony said, and Peter believed him. “The only thing this changes is that I can do this now.”
The kiss was as soft and as sweet as Tony could make it. For years, he had watched Peter, seen the adoration and infatuation in the younger man’s eyes, and ignored it. For as much as Tony loved Peter’s brain, he knew he would want more, would be unable to keep his hands off the kid if they had been dating, and betas found it hard to take his sheer size, so he always held back.
But now, now he didn’t have to.
“What do you think? Be my omega? Let me have you?” Tony asked as he drew back, smirking at Peter’s dazed look.
“I-wha- do you mean it?” Peter asked breathlessly. Tony couldn’t help but kiss him soundly in response.
“The only thing that held me back was fear of hurting you if your body couldn’t take mine,” Tony replied fervently. “Otherwise, I would have made you mine long before now.”
Peter groaned and initiated a kiss of his own.
“Please, please, alpha,” Peter begged as he pulled back again.
“Of course, omega-mine,” Tony rumbled, giving Peter one last kiss before stepping away and standing up.
He chuckled as Peter whined, but he wanted to take a minute to enjoy the view. And honestly, the opportunity was too good to pass up.
“What do to now, little omega?” Tony rumbled, his hands roaming over Peter’s back before finally letting one hand slip down between his legs. “I could have been having you this whole time, and now, here you are presenting so prettily for me.”
“Please, alpha,” Peter panted, trying to push back against Tony’s fingers as he played with the edges of Peter’s slit.
“I can’t just give you what you want when you’ve been so naughty, though, and as your alpha, it’s my job to correct that,” Tony said, bringing his hand back to Peter’s ass. “Isn’t that right, omega?”
“Yes, alpha. All yours, alpha, yours to punish,” Peter said with a whimper.
“Good boy,” Tony said, gently squeezing the omega’s ass. “So, your punishment will be 2 spankings per year you denied us being together by lying. Given that I met you when you were 14, that means 5 years, so 10 total.”
Peter whimpered again but didn’t move as Tony spoke. He was looking forward to reddening that ass and then claiming him properly.
“You don’t have to count this time, but I expect you to hold still,” Tony said firmly. Without any further warning, Tony applied himself to the punishment.
Peter gasped and then moaned at the weight of Tony’s hand against his ass. It stung and burned but also fanned the need in his body, and with each hit, it was harder to stand still. Slick dripped from his cunt, and ten seemed like too many and yet not enough. When Tony was done, Peter was panting and whining, straining to get closer to his alpha.
“Such a good omega,” Tony said, stepping close so he was pressed up against Peter’s ass. The alpha’s body heat was a balm on his sensitive skin but also a tease as he felt Tony’s heavy cock pressed against him as well.
“Alpha, please,” Peter begged, feeling more needy than he could ever remember. “Please, please, please, need you, alpha.”
Tony froze when Peter started begging in truth. Later, he would blame it on the decontamination room soap and air filters, but in the moment, all he could think was, ‘Oh shit.’
The sweet smell and neediness could only be Peter’s heat coming on suddenly and more strongly than Tony had ever seen. Their compatibility must have been high because his rut triggered almost immediately in response, and his focus narrowed to breeding his new mate.
He wasted no time prepping the omega, though sheer wetness made it nearly unnecessary. Then he was shoving his cock deep into Peter’s cunt. Later, Tony would show him soft, gentle sex that brought him to tears, but for now, all he could do was pound into the younger omega.
His knot popped so fast, he nearly passed out, body draped over Peter’s back as he blindly reached for the omega’s cocklet. Tony grabbed it and started stroking it until he felt Peter shudder beneath him, his cock being squeezed even tighter as Peter came.
Tony knotted Peter three more times standing before he finally had enough clarity of mind to have Friday send a few suits to break Peter’s hands free. She also had the forethought to clear the path to his penthouse and have everything they’d need for a heat set aside, which was good because even just the trip there had Tony burning with desire and Peter begging for more.
“Fuck, kid, I’ve never had a rut hit so hard,” Tony groaned as they lay sprawled on the bed, sanity having finally returned to them both. He dreaded asking what day it was so he simply ignored it as he let Peter snuggle against him. “Also, can’t believe you made me wait 5 years for this. We could have been having amazing sex and cuddling after the whole time.”
“Sorry, sir,” Peter replied shyly. “We’ll just have to make up for it now.”
“Damn straight,” Tony agreed, pulling Peter in for a searing kiss. “Probably have to take a rain check, though, as I’m pretty sure they’re going to be breaking down the door if we don’t make an appearance soon.”
“What? Why?” Peter asked, his eyes wide.
“Someone’s gonna think I kidnapped you or something,” Tony said with a chuckle. “That, and I’m sure Captain Pirate still wants a debrief. He gets so impatient, after all. You’d think he’d be used to waiting on my awesomeness.”
