“Uh, Mister Stark?” Peter sounds scared, and Tony looks up from his phone to see an honest to god flying saucer hovering above them.
“Wha the fu-?”
Before either of them can say anything else, a beam of glowing blue-green light shoots out of the bottom of the spaceship and they start to float off the roof.
“Mister Stark!”
“It’s okay, kid, just stay calm,” He makes eye contact with Peter, hoping if he sees Tony being calm (at least on the outside), that he’ll stay calm, too. “Maybe- maybe they’re friendly, and just need some Avengers help, huh?”
Peter nods, but doesn’t look convinced. As they pass through the opening into the ship, a blinding white light takes over Tony’s vision, and then…nothingness…
He wakes with a jolt, sitting up quickly, and looking around. The room has rounded walls, almost like a fishbowl, and Tony’s head is on a frantic swivel. He spots Peter, slumped on the floor, a few feet away and Tony scrambles over. “Pete? Kid, c’mon,” He gently shakes him. Peter comes up swinging, and Tony quickly grabs his wrists. “Hey, hey, just me!”
“Mis’er Stark?” Peter’s eyes are wide, scared. “What?”
“I don’t know, but we must be on the alien ship.”
Peter nods, and sits up properly, legs splayed out in front of him, as he looks around.
Suddenly, a voice comes from…somewhere. It sounds like they’re being surrounded by it. “Ah. you’re awake,”
“What the hell is this?” Tony shouts.
“Fear not, we are research scientists, and wish you no harm,” The voice says.
Tony snorts. “Coulda fooled me,” He mutters.
“We are studying Earthling copulation, and require you to complete the ritual for our research.”
“Excuse me?”
“What?!”
Tony and Peter both exclaim at once, looking at each other.
“Per our scans, you are each what Earthings call man and woman-“
“I’m a boy!”
There’s a pause. “But you possess the female Earthling’s copulation organs.”
“Stop saying copulation,” Tony grimaces.
“Sometimes boy have vaginas and sometimes girls have penises, it’s called-”
“Kid,” Tony sighs. “I don’t think the sex aliens particularly care about transness.”
Peter pouts, but nods and doesn’t try to elaborate further. Tony just wants to get them off this damn ship without having to copulate for these weirdos. The problem is, he has no clue how to do that. There doesn’t seem to be a door on this room, the walls are all smooth and rounded, which also makes Tony wonder how they’re being observed. Whatever access point there is into the room must be a seamless sliding door.
The alien suddenly sighs, making it sound so human, and it throws Tony off a bit. “Very well, if you won’t cooperate-”
“Mister Stark…”
Tony knows that tone, that means the kid’s spider sense is tingling. It only takes a few seconds, but then Tony feels like he’s going to pass out. They’re drugging them, he realizes, just as his vision goes dark.
This time, when Tony wakes up, he’s naked, sprawled across the floor. Lifting his head, he looks down his own body and sees that his cock is hard. Huh. Looking around, he spots Peter, also naked, sitting up, and curled up in a ball, knees to his chest. He’s clearly trying to hide his body, and Tony’s heart breaks.
“You okay? Other than the- ya know?” Tony sits up and crosses his legs, putting his hands in his lap to cover himself.
Peter glances over at him and nods.
“Kid- I don’t think we’re gonna get out of this without-“ Tony sighs. “Without doing what they want.”
“I know,” Peter whispers. “I’m just glad ‘m here with you and not- not someone else.”
“You are correct,” Comes the alien’s voice again. “Once we have observed and recorded the copulation, you will be free to go.”
Tony nods, once, mostly to steel himself. Then. he moves to his hands and knees and slowly crawls over to Peter. Gently, he guides the kid to lay back, and moves between his legs. “Gonna touch you, now,”
Peter nods, bottom lip trapped between his teeth.
Reaching forward, Tony lays his hand on Peter’s thigh, moving it upward with determination. He instructs Peter to open his legs a little more, and Peter moves until his knees are bent, thighs spread. Tony goes to try and finger Peter, not wanting to hurt him, when he’s stopped harshly.
“Copulation only!”
“I have to stretch him!” Tony protests, trying not to think about the way Peter whimpers, sounding scared.
“We have already provided a substance that will relax and provide natural lubricetion,” The alien says.
Sighing, Tony drops his chin to his chest. Right. “Alright, kid, let’s- let’s do this.”
“Okay,” Peter agrees, a determined look overtaking his features.
Tony hates that this is going to be Peter’s first time.
Grabbing hold of the base of his cock, Tony guides himself to Peter’s entrance. As the tip of his cock touches, Tony hesitates for only a second, looking up at Peter’s face. The kid nods, and Tony slowly pushes forward.
He’s so hot and tight, gripping around Tony’s cock like a vice as he slides in in one slow, smooth push. Tony can’t take his eyes off of the way Peter’s hole is stretched around his cock. Fuck. He chooses to blame the pleasure coursing through his veins on whatever drug they pumped him full of.
“Mister Stark?” Peter’s voice is soft, strangled.
“Yeah?”
“Move, please,” The kid requests.
Tony pulls his hips back, slowly sliding his cock out, then pushes forward. Whatever they gave Peter has made him so slick, he glides in and out of the kid’s pussy with ease.
Peter makes a little moaning sound. and for some reason, that’s all it takes for Tony’s hind brain to decide he can speed up. He grabs Peter’s hips and starts a quick, steady rhythm, balls slapping against Peter’s skin. It sounds obscene in their fishbowl prison.
Whatever drug these aliens gave them is making Tony climb towards his orgasm quickly, and this is all going to be over with just a few more thrusts. Intuition tells him these fuckers aren’t going to let Tony pull out, so he warns the kid before he explodes, hips stilling with his cock deep inside of Peter.
His balls have barely stopped pumping cum into the kid when his vision goes black again.
