Work Text:
Tony woke up in a cell, a small one. He had been kept here for months now, brainwashed and forced to do Hydra’s dirty work, he hated it. Today was no different. He barely had time to wake up before he was dragged out of his cell, dressed and ready for a mission. It was a mission like any other. Go in, take some files, kill whoever gets in your way, go out. He had done this many times before, especially during these last few months. He wasn’t given much information about the victim, other than that his name was Richard.
He left in a jet, and once that landed he took his motorcycle into town, heading for the house. After parking outside the decently sized house, he went inside. It was silent, very silent, which worried Stark quite a lot. But he didn’t let that stop him. After looking around the house for a minute, he found the office. And on the desk, the files. His mission was simple: grab the files. He opened one of them, skimming through it, it seemed to be some form of experiment involving spiders or something, he didn’t read through it properly. After gathering all the files and putting them in his backpack, it was time to leave. Only, he didn’t make it that far before he was hit in the back of the head with something hard. It knocked him to his knees, but he was back on his feet again just as quickly. There stood a man, ready to fight, too bad he wouldn’t survive this. A few punches to the face and the man was left on the floor in a puddle of his own blood.
That’s when Tony heard it, a faint whine, almost a little scream. He followed the noise to a room, a baby room. And in the middle of the room, a crib, with a little kid standing in it staring back at Tony. The kid couldn’t be more than a year old, and judging by the colors of the room, Tony guessed it was a boy. Should he leave the kid? The man outside the room, presumably the dad, was dead. What if no one else came home? The kid would starve to death in his crib or something. Although bringing him to Hydra wasn’t a good idea either. The boy stared at him then cooed, a toothless smile showing, it melted Tony’s heart. With a sigh, he wrapped the kid up in a blanket and brought him with him. The kid cried the whole motorcycle ride, but calmed down and fell asleep in Tony’s arms on the jet.
When he got back to the Hydra base, his Captain was definitely not happy seeing a stolen kid. They pulled the little boy out of Tony’s arms, Tony did resist but they just used their commands and he was back in his cell in the blink of an eye. After that, he didn’t see the kid again, assuming they either put him back or killed him.
About 5 years passed and Tony was walking down the hall, he’d just gotten back from assassinating someone. As he walked past one of the lab halls, he stopped and looked in through the big glass window. There, on a table surrounded by men in white lab coats, sat a young brown haired boy, around the age of 6. The boy sat in nothing but underwear, sucking on a lollipop while his little legs swung back and forth slowly. He didn’t seem bothered at all by the old men running around him, testing his blood and babbling in another language, the boy seemed used to it.
Tony immediately wanted to investigate. He slipped in unnoticed, making his way closer until he was close enough to take a proper look at the boy. When he looked into his eyes, he immediately recognized him, it was the baby he took, it was still alive.
“Soldier!” Tony looked around and saw his Captain standing at the door, looking mad. He immediately followed him out of the room, giving a status report on his latest mission.
For the next few years, Tony saw the boy more and more, watched him grow. He got to talk to him more often, actually got pretty close to the kid. He found out the boy could crawl on walls, that was pretty dope, he was definitely gonna be used as a soldier for Hydra. By the time the boy, who’s name was Peter, had turned 16, Tony was in his late 40s. His beard had begun to gray a little, but thanks to Hydra he was still in good shape, although he wasn’t doing as many missions as he used to.
“What about Stark? We gonna kill him? He’s an old soldier, we have better ones now, like the spider boy. We should have more of him.” One of the lab coats said, to which the Captain only hummed in agreement.
“we should have more of him, shouldn’t we?” he chuckled. “Maybe Stark can be of some use to us after all”
The next day Tony was taken as usual, he expected yet another mission, but was surprised when he was brought into the lab where people were waiting. He was laid out on a table, and just as he began to worry, he felt a needle in him, and then he blacked out. When he woke up, he was naked in a bed in restraints.
“What the..” he pulled a little on the restraints then looked up when he noticed he wasn’t alone. “Peter…”
The boy stared at him, then grinned and walked closer. His pupils were dark and wide, he was as naked as Tony and had this weird lust in his eyes that gave Tony shivers. The kid got on the bed, crawled over. Tony noted that the 16 year old was pretty buff for his age, probably thanks to experiments. Not to mention, his cock was massive, it almost looked out of place on the young man’s body.
“Hello Mr. Stark, good morning.. you were out for quite a while, I guess the surgery took a lot out of you..” The kid said in a quiet tone, settling beside Tony on the bed.
Tony wasn’t sure what to say or think. “Surgery..?” he asked, a little confused.
The boy just smiled, but one of his strong hands on Tony, right on the arc reactor which made Tony tense up, then the hand slowly traveled down his body. “Captain said it was all for me.. and I am definitely happy with the results.. you're mine now, my play thing..” Peter said with a smirk. As his hand traveled lower, Tony began to sweat.
“kid, let me out of these bonds…” Tony pulled a little more this time, trying to wiggle out of Peter’s touch, but it didn’t work.
Peter’s skinny fingers continued on to travel down his body, until eventually he reached that spot. Tony expected the usual feeling, the way it should feel when his cock is touched. Bit it felt different. He had been too busy staring at the kid to even notice what changes had even happened to his own body. As he looked down, expecting to see his usual cock, he instead found a vagina. No cock, no balls, a hole. He breathed in, his mind going blank. What the hell was going on? Was he dreaming? He didn’t have any time to reflect over this, because Peter’s fingers had reached their destination, and without second thought, the boy pushed a finger in, passed Tony’s folds and rim, deep in.
Tony hissed, he’d never felt anything quite like this. His new hole was overly sensetive and already gushing out wetness as Peter began to fuck Tony with a finger. It burned at first, but just as he was getting used to the sensations, another finger was added. By now the kid was rock hard, looking even bigger than before. His cock was not only abnormally long, but the girth.
Tony’s mind was still fuzzy, he wasn’t sure what was happening, but the kid seemed to be getting impatient with the fingering because all of a sudden he slammed in two fingers at once, moving all four fingers around a little before pulling them all out.
“Captain told me to do as I pleased, that you’re retired and just my plaything now. Don’t worry sir, I will take good care if you.” The boy said while rubbing Tony’s sides, giving him an innocent smile, but his eyes still had the look of lust. The boy grabbed his cock, gave it a few strokes using both hands, then he pushed the tip into Tony. He was impatient, beginning to force the length into Tony, ignoring the drops of blood that left Tony’s brand new pussy and the silent screams the old man let out.
It left Tony shaking, whimpering and groaning in pain “k-kid..”
“shh, pet, it’s gonna be okay” Peter rubbed Tony’s cheek and pulled his cock out then back in, going all the way, watching as the old man’s stomach bulged at the size, he looked so beautiful like this. “You’ll like it soon, I promise” Peter gripped his hips hard, beginning to force his cock in and out of Stark at a brutal pace, having Tony groaning and squirming around an awful lot as blood kept gushing out of his pussy.
It took a while, but eventually the kid stilled, looking very concentrated for some reason. Then he groaned, and Tony looked worried, “hey, what’s happening..” he asked but he was about to find out himself. Something nudged his rim, like it was traveling through Peter’s cock. He groaned, feeling the roundish object force itself past his inner rim and into his body, settling low in his belly. It felt like the size of an apple, but inside Tony it felt like it swelled, which it must’ve done because his belly began to bulge out more.
Tony groaned and stared at his bloated tummy, it wasn’t too bad, but then he felt another lump force itself into his body. Peter was shooting something into him, it felt kind of like eggs, like a spider laying eggs in him. Peter seemed too distracted on his own stuff, pushing in two more of the round things, leaving four in total inside Tony's body. The small balls grew in him, just one had been fine, but when four of them grew in him like this, it hurt, stretching his stomach way too much until he was left with a belly that could only be described as a pregnancy belly, a pretty big one.
Peter panted, he was sweating and exhausted, but oh he looked proud alright. “Look at you pet…” he came to put his hands on Tony’s stretched out belly, rubbing over the tender skin. After that he reached up and undid the bonds, setting Tony's arms free.
Tony immediately touched the belly, it was hard and a little bumpy, when he pressed down he could feel the oval shapes in him, four big ones, filling him out to make him look like he was at least 6 months pregnant. It hurt a lot, he struggled to even sit up but when he finally did, he just stared down at his body. His cock had been taken and replaced by a pussy, and his belly had been filled with something that Tony guessed were eggs, Peter’s eggs. He looked up at the young boy, Peter just smiled back.
“Don’t worry, they will only stay in there a few months. And I will take such good care of you,
pet
” Peter said and walked over, petting Tony’s hair gently.
A few months passed, Tony had been taught to listen to his new master, and if he disobeyed he was punished which he hated, so he settled for following Peter. His master had gifted him a collar, so everyone knew who he belonged to, and his belly stayed the same round shape for months. Tony had gotten used to the belly by now, it was uncomfortable but Peter always said it made him beautiful. And like Peter had said he would, he took great care of his pet, pleasuring him and feeding him.
But one day Tony woke up to feel sharp pains, it went on all day, and when Peter finally heard about it he just smiled, "the eggs are ready"
He had Tony put down on a blanket where he stayed curled up whimpering for a while, he could feel his hole streching out more, but he couldn't see it thanks to the belly. Eventually the pain became too much, his natural instinct was to push so that's what he did. When he reached down around his belly to his pussy, he couldd feel how strehced open it really was, then he felt something hard and slimy, it must be an egg.
It took almost an hour of pained pushing, but eventually an egg came out, leaving Tony panting. The egg was massive, of course it had taken long to get out, he was surprised he even managed to. But there were still three left.
"You're doing so good pet" Peter said in a soothing voice, petting Tony's hair for a moment before picking up the egg, which had started hacthing. Peter helped the egg a little, and inside was a human baby, it at least looked like one. A Hydra agent came in and took the baby away, Tony was pushing out future Hydra agents.
Another sharp pain had Tony's mind back to what he was really doing. The second egg took about as long as the first, Tony felt like he was gonna pass out from exhaustion, but the thrid and fourth egg came out faster, leaving Tony feeling empty, his belly sagging a little.
Afterwards he was praised by Peter, given food and massages, he was actually very happy. He even got to see the babies.
His pussy needed recovering, but the second Peter got his chance, he filled Tony up again, five eggs this time.
Tony just sighed and nuzzled Peter, while rubbing his belly, this was his life now.
