Waking up 50 years into the future was terrible. All his friends and family were twice his age and had moved on. The only reason Steve kept going was for his godson. The Stark heir who was left orphaned by his parents death at the age of 8. Shortly after meeting Tony, Steve decided to adopt him. He wanted to raise Tony as his own. Most people praised him, Peggy was proud of him. Steve adopted Tony because he loved him, he really loved him.
Steve knew what he was doing was wrong. Downright sick. But he couldn’t help it. It started off small as most things do. He only snuck into Tony’s room to make sure he was sleeping. To make sure he was safe. He then started touching him. Just small touches. A caress here a little fondling there but then Tony hit puberty.
Tony was gorgeous. Big doe eyes and a mop of curly brown hair. A feminine face and petit figure. The way his eyes sparkled when he smiled. The way he filled out his pants and his small pink nipples. It all left Steve drooling.
At 14 Tony started to masturbate. He didn’t just jerk off no he masturbated anally. Steve saw the bottle of lube soon as Tony snuck it into the house. He had to check to see where the lube was going. Carefully after Tony had fallen asleep Steve, snuck into his bedroom.
“Pardon the intrusion” Steve whispered to himself. He knew Tony wouldn’t be waking up, due to the sleeping pills Steve always put in his food. Tony was gently snoring, sleeping on his stomach. Steve moved the blanket to see the small curled-up body. There were tissue papers under his blanket. Looks like Tony fell asleep after jerking off.
Steve adjusted Tony’s body a bit before pulling his trousers down. His soft thighs parted easily as Steve manhandled him into position. His legs were spread open. Steve groped his soft ass cheeks before spreading them open.
“Good God” Steve gasped sharply. Tony’s pink pucker was still slick and shiny from when he masturbated. Steve brought his index finger to touch the slightly swollen rim. He met a little resistance but pushed in fairly easily. One finger slowly became two, then three and then four. He used a lot of lube which was making loud squelching noises.
“Naughty boy, taking daddy’s fingers in like a born slut.” Steve chuckled at how lewdly Tony’s young body was sucking his fingers inside.
“You’re so hungry aren’t you? Hungry for a real hard cock.” Steve undid his pants and pulled out his raging hard cock. He didn’t bother with a condom. After adding more lube to his cock, he positioned himself right at Tony’s hole.
“It’s feeding time slut.” Steve slowly teased his cock inside. He pulled it out before pushing back in. He was enjoying stretching Tony’s rim with the slow pulls. Tony on the other hand was shaking. He was whimpering, still unable to wake up. Steve reached his hand around to feel Tony’s small cock. He was hard and extremely wet with precum.
“Aw, your poor cocklet is hard. You want to come don’t you?” Steve teased Tony, he always teased Tony relentlessly when he was asleep. While awake he was the perfect uncle to Tony. Always praising and encouraging the smart little slut.
However, Steve was done playing nice. He wanted Tony and tonight he was going to get him. He started picking up the pace. He moved fast in and out. Slamming into Tony fast and furiously. He was going at a punishing pace. Fucking him hard into the bed. Steve felt he was close.
Steve not only took Tony’s virginity but this was the first time he was going to come inside of anyone. Steve was very excited. When he comes, he comes hard and lots. With one brutal thrust, Steve released inside. He felt Tony struggle to keep all the come inside.
Steve wasn’t even close to being done. He had no refractory period. Steve turned Tony on his back. He pushed Tony’s legs apart and noticed the wet limp cock.
“Baby, you came from your ass? God, you really are a slut.” Steve told Tony cruelly. He pushed Tony’s legs wide before fucking him again. Steve almost crushed Tony’s body with his thrusts. He came inside Tony many times. So much so that Tony’s stomach was bulging.
Steve pushed in deep one last time before releasing. However, he wasn’t satisfied. Steve drank a lot of water that day. He hasn’t gone to the washroom either. He wanted to piss inside Tony. Degrade and disrespect Tony by peeing inside him. Steve pushed in hard and started to relax. With one more look at Tony’s face, Steve started to let go.
A gentle stream became fast and hard quickly. Tony’s stomach was building a lot now. Tony was struggling to keep all the urine inside. It started streaming down his thighs and wet the bed sheet underneath him. Steve kept going until he was done. Tony was now whimpering and panting.
Tony was completely debauched. Covered in lots of bodily fluids. Steve slowly pulled out. As soon as he did that cum and piss started pouring out of his gaping hole. It was swollen and pink. Steve covered Tony in the blanket before leaving. He was very excited to hear Tony’s reaction the next day. Luckily no one was going to be in the Stark mansion in the morning. Steve was the only person who would see his shameful state.
~~~~~~~~~~~~~~~
Tony woke up feeling sore and sticky. It hurt moving his legs and back. He was really confused. He read instructions on how to masturbate anally. He was very safe and careful about it. He felt really good when he went to sleep but everything hurts now. He moved his blanket to see he wasn’t wearing any pants. He swears that he remembers putting them back on before falling asleep. It also smelled really bad like urine. Did he wet the bed too? He was trying to figure out what happened when someone knocked on his door.
“Tony, are you awake?” Tony was terrified. It was his uncle. No this couldn’t be happening, under no circumstances is Steve allowed to see him in this state. He quickly pulled the blanket up but it was too late. Steve opened the door and saw Tony’s panicked face.
“Hey sweetie, good morning.” Tony tried stuttering back a good morning but his uncle was coming close. Any second he’d notice what Tony’s done. He was bracing himself for the yelling. For the hatred and disgust. God Howard was right, Tony really is a disappointment. His eyes started tearing up. He could feel the tears that were threatening to spill. His uncle grew worried at that look on his face.
“Tony, what's wrong? Why-” His uncle saw the wet blanket.
“Oh no Tony, did you have an accident?” An accident, he’s 14 and he’d wet the bed after he masturbated. He was shaking and crying now. Steve moved the blanket and saw the disgusting mess and to his surprise, Steve wasn’t upset.
“No baby, don't cry, It’s okay, this is nothing to be ashamed of.” What was he saying, this was 100% something he should be ashamed of.
“U-uncle I’m s-sorry,” Tony sobbed out. Steve just hushed him and picked him up. He carried Tony bridal style effortlessly to the bathroom. He set him down gently onto the tiled floor. He took Tony’s shirt off and then his own clothes off.
Under the streams of the warm water, he washed Tony’s hair. He washed his body with soap and water. He had to clean everywhere. He grabbed the handheld water spray and turned off the shower. He guided Tony to the wall and started pushing his legs apart.
“Tony, could you bend and hold yourself open. I need to clean you inside.” Tony was blushing so hard. This was so humiliating. He wanted to curl up and die. With shaky fingers, he reached back and spread his ass cheeks. He bent a little forward to give his uncle better access. Steve turned the spray on. The warm water was hitting his sore rim, it felt good.
Steve soaped up one of his hands and touched him. Tony let out a tiny whimper. Steve worked his fingers inside and out. Thoroughly cleaning Tony. The thick fingers felt so different than anything he had ever felt in his life. His uncle’s fingers were much bigger than his own. He wondered what it would feel like to masturbate using his uncle’s fingers. Tony really was disgusting, to be thinking such dirty thoughts about his own uncle.
Steve turned the pressure up. He pushed the spray against his rim. He felt the water go inside him. He started getting hard. He didn’t even notice the fact he was outright panting and moaning.
‘God this slut’ Steve thought to himself. He wanted fuck him so badly. He wondered what Tony’s reaction would be to getting fucked in his own bathroom by his uncle. He’d probably enjoy it. He would beg and plead for more like the needy whore he is. Steve turned off the spray, he had other plans for Tony today.
Tony moaned loudly when the spray was turned off. In the dead silence of the bathroom, Tony realized how loud he was. He quickly straightened up, he wanted to leave the washroom now before he humiliates himself any further. Steve grabbed Tony and picked him up again before he could leave.
“U-uncle what are you gonna do now?” Tony asked nervously as his uncle carried him. Tony was put down on a bed. He realized it was Steve’s bed. Steve gently nudged Tony onto his stomach.
“Tony you seemed loose, I want to check you to make sure there’s nothing wrong with you.” That was an excuse. Steve just wanted to finger fuck Tony while he was awake. Steve left to get some lube and latex gloves. He propped Tony up on his knees and elbows. He pushed his thighs apart.
“Tony I want you to relax, this might hurt a bit.” That was a lie, Steve was very sure that Tony was going to enjoy this. He uncapped the lube bottle and poured a big glob onto his fingers. He pulled Tony’s cheeks to get a good look at that pucker. Tony was blushing and trembling a lot. Steve pushed in a finger.
“I just need to check your prostate, Tony.”
“O-okay Uncle.”
He pushed his finger in deep. He twisted around looking for the spot which would make Tony lose control. His plan was to make Tony cum from his ass. Make Tony realize how little control he had over his own body. Make him reliant on Steve. He pushed in another finger. Started twisting around until.
“AAuuh,” Tony moaned lewdly. Bingo, he found the spot. He pulled out and used his fingers to stretch Tony open. He tipped the bottle of lube and poured the lube directly into Tony. He heated up the lube earlier so the warm lube must’ve felt good. He began pistoning his fingers in and out, hitting his prostate dead on. Tony squirmed and trembled. He felt like he was going to cum. His mind was getting foggy. With one hard thrust, he felt himself come undone. He came while shaking and sobbing.
He fell forward, all strength leaving his body. He heard his uncle take his glove off. He felt gentle fingers play with his hair. He just wanted to burrow deep into the bed and never come out.
“Tony it felt like your prostate was enlarged, do you perhaps masturbate anally?” Steve asked him so bluntly. There was no point in hiding anymore. Tony mumbled out yes.
“Okay, I'm not mad or disgusted by you, but I think you should be more careful. Your body seems very sensitive, I wouldn’t want you to break it.” His uncle was so nice. He was so sweet and understanding. Tony turned to his uncle and gave him a big hug. He promised to be more careful.
~~~~~~~~~~~~~~~
Tony decided that he wasn’t going to be masturbating before bed anymore. He also made sure to use the washroom before going to sleep. He was never going to wake up in a wet bed again. He confidently went to sleep.
In the cover of the night, Steve once again snuck into his room. He crept into the bed and had his way with Tony. He fucked Tony in many different positions. He ended the night by once again peeing inside him.
The next day Tony again woke up in a wet bed. He tried to get rid of the evidence before his uncle noticed but he was too late. This time instead of cleaning him in the shower, he suggested a different way to clean his insides. Steve left Tony naked on all fours in the shower. He came back with a bag and nozzle.
“Uncle, what is that?” Tony had no idea what his uncle had.
“It’s going to clean you inside.” Is all Steve said. He crouched down to Tony’s ass. He took some lube and loosened Tony up with his fingers for the enema nozzle. Without hesitation, he started pushing the nozzle and tube in deep. He then let the warm soapy liquid pour inside.
Tony immediately tensed up. He was getting filled up from the back. The water gushed inside him. His stomach started stretching. He was groaning with all the effort it took to keep the liquid inside. Steve reached down to touch his bloated stomach. Tony’s stomach looked huge and pregnant. Finally, all the enema water finished pouring inside him.
“Tony, I need you to keep it inside before releasing it all down the drain.” Tony was red, he didn’t want to do this in front of his uncle. He felt the long tube be pulled out. He was sweating with all the effort it took to keep all the water inside. Tony looked miserable trying to keep it all inside. Steve wanted to see how long Tony could keep it inside.
“Alright, sweetie let go.” And with that, he let go. All that waste came out, Steve quickly helped wash it away with the water spray. By the end of it, Tony could barely stand on his own legs. Steve carried him to his bedroom again. Tony promised Steve it was the last time he was going to have an accident. Steve agreed while smirking to himself.
~~~~~~~~~~~~~~~
“Tony, I think it’s time we take extra precautions.” Tony knew this was coming. He had been wetting the bed for the past two weeks. No matter what he did he woke up in a wet bed. His uncle has been cleaning his bed and cleaning him with enemas. He was very grateful to him.
So when his uncle suggested extra precautions he agreed. He had no idea what the extra precautions were but it can’t be worse than anything he has already been through. He is waiting patiently on his bed for his uncle. His uncle came in holding a box. Tony tensed as soon as he saw what the box was.
“No, uncle I can’t wear those!” It was a box of diapers. He can’t believe what his uncle was suggesting. He was 14 for god sake.
“Now Tony please don’t fuss, this is for your own good. Until you learn how to control yourself. You’re going to be wearing diapers, understood?” Steve said this in a no-nonsense voice which left no room for argument. Tony however wasn’t going to accept this lying down. He got up from his bed and got further away from Steve.
“No, I’m not wearing those!” Tony screamed at his uncle. At this Steve got mad. How dare he talk back to him. He dropped the diapers on the bed and walked with heavy footsteps to Tony. He grabbed Tony roughly before pulling him back to the bed. Tony started thrashing and fighting. Steve sat down and then pulled Tony over his lap. He ripped Tony’s pants off and pulled his underwear off. He stared at the round rump, he brought his hands down on it. He spanked Tony’s ass. He didn’t stop till Tony was sobbing. He kept going till Tony was apologizing and begging him to stop.
“U-uncle p-please stop-p,” he was choking on his own sobs.
“Will you be a good boy Tony?” Steve asked in a husky voice. Tony nodded his head. He won’t fight anymore. His uncle knows best, he should’ve listened to him from the start. Steve smiled at that. He set Tony on his back, the bedsheet rough on his sore red behind.
He was still sniffling when Steve slid the thick diaper under his ass. Steve got cream and rubbed it between his ass, under his balls, anywhere he might chafe. He powered on some talcum powder. He pulled the diaper on tight. He gave the diaper a squeeze. Tony’s legs were bowed due to the thickness of the diaper.
Tony couldn’t close his legs even if he tried. He leaned down and kissed Tony’s cheeks. Promising him that if he was good tonight, he didn’t need to wear them again. He tucked him into bed and left.
It felt weird trying to sleep in a diaper. He did like how soft and safe it felt. That’s when it hit him. He didn’t use the washroom before bed. He couldn’t go now though because his uncle already put the diaper on him. He definitely didn’t wanna pee in the diaper. He just squeezed his stomach and hoped to god he didn’t wet his diaper by morning.
~~~~~~~~~~~~~~~
Steve was ecstatic. He finally could have Tony completely. It’s been his fantasy to have Tony as his helpless baby for the longest time. He would have Tony reliant on him. He came into his bedroom. There he was, sleeping innocently on his stomach. Curled up, waiting to be taken.
Steve groped the padded behind. He wasn’t surprised that it was dry. It would take a while before he could convince Tony to use it on his own. He pulled Tony in close and humped the behind. He pulled the diaper aside to look at his hairless asshole. Steve put hormone pills into Tony’s food to make him unable to grow body hair. With quick thrusts, he came on it.
He snuck dick into the back of the diaper. He got Tony in position before peeing in his diaper. He pissed a lot. Tony’s diaper was getting warm with his piss. Tony himself might pee if his diaper was already wet in the morning. When he finished he pushed Tony on his back. The diaper was enlarged because of the piss. It really looked like Tony peed.
He pulled Tony’s blanket back on top of him. He gave him a kiss and left. It was going to be a tear-filled morning for him.
Tony woke up in a warm and full diaper. He actually wet the diaper! He knows that he has been wetting the bed but he was hoping he wouldn’t pee in the diaper. What was weird was the fact even though the diaper was very full, he still had the urge to urinate. He waited in bed for Steve to come. He had no idea what to do with himself in the wet diaper.
“Hello, good morning baby.” Steve was happy to see that Tony was already awake. He went and picked Tony up. He set him down on his lap. He took his hand and gave Tony’s wet diaper a squeeze.
“Pretty full huh?” Steve chuckled. Tony was mortified. He was sitting in a wet diaper on his uncle’s lap.
“I don’t understand, how can I still need to pee when I already wet myself,” Tony sobbed. He was very frustrated.
“Sweetie if you need to pee then let go, use the diaper.” No, he didn’t want to do that. He was already awake, what was the point in using the diaper?
“Baby don’t make me ask twice,” Steve warned him, he didn’t want to start the day off by punishing him. But he will punish him if he has to. With a little more encouragement Tony let go. He pissed really hard inside his already wet diaper.
Steve reached down and felt Tony peeing. He was sure that any second the diaper would overflow. Tony was moaning by the time he was done. Tony didn’t say anything as Steve picked him up and put him on a changing table. When did he buy a changing table?
He quietly undid Tony’s filled diaper. He wiped Tony clean. He gave him an enema in the shower. Before leaving the washroom he put him down on the changing table again. This time he lubed up a butt plug.
“W-what is that uncle?”
“It’s a plug, I want you to get comfortable wearing it. This will help you control yourself better.” Steve gave a vague excuse. He just wants Tony to wear a butt plug 24/7. This was just another way of controlling Tony. He even convinced Tony to wear panties. He loved the thought of Tony going throughout his day, meeting with his tutors and working in his workshop all while wearing a plug and panties. With a smack to his ass, he sent Tony off.
~~~~~~~~~~~~~~~
It felt strange wearing a plug the whole day. Tony thought he was going to hate it but he didn’t. Every time he shifted he was reminded of his uncle who was trying very hard to help. It got him through his day. At night he was waiting by his bed for his uncle again. He was a little less embarrassed to wear a diaper his second time around.
“Hey baby, how was your day?” Steve inquired.
“Not bad I guess.” Tony lay on his bed waiting for him. Steve took his pants off and his panties. He looked so cute in them. Almost a shame he had to take them off. He wiped him down, rubbed the cream on his privates and powdered on the talcum powder.
“Aren’t you going to take the plug out?” Tony asked when he realized the diaper was being taped on and the plug was still inside.
“No, I want to avoid any other types of accidents,” Steve grinned. Tony let his uncle tuck him in and kiss him goodnight. At this point, Tony has accepted the fact he can’t control his bladder. He doesn’t even control his bowel movements because of his morning enemas. He was tired, he was tired of trying to control himself. He just wanted his uncle to do everything.
When Steve came back that night he was surprised to see the diaper full.
“Aw baby did you wet yourself completely on your own?” Steve felt the wet diaper. His baby was so good. He had emptied himself without his daddy’s help. He deserved a reward for that. The plug he was wearing wasn’t a regular plug. It was a vibrating one. He took out the remote and turned the plug on using the lowest setting.
It came to life with a loud “vrrrr”. Tony jolted, his ass shaking because of the plug. Even the lowest setting is easily the highest on most vibrators. He had this plug specially made for Tony. It was going to make him lose his mind in pleasure.
Tony’s small cock started rising. He saw the small bump on the diaper. He gave it a little squeeze and turned the plug on higher. His bowed legs started shaking. He was close to coming. It didn’t take a lot for Tony to squirt. He turned the plug to a higher setting. A couple of minutes went by and Tony came in his diaper.
“Naughty baby, cumming in his diaper without asking daddy.” Steve tsked, he pulled Tony close and kissed his head. He didn’t bother fucking Tony tonight. He was satisfied and left.
The next morning Tony woke up fairly happy. Even though he wet himself again, he felt relaxed.
“Good morning sweetheart.” Steve strode into his room and gave Tony a hug. Tony nuzzled into him.
“How are you feeling?” Steve was really curious why Tony was so happy. Is he finally accepting his place under his care?
“I feel good daddy.” He said it so casually. Tony himself probably didn’t notice but Steve did. He did it. Tony was his baby. He swore to himself that he’ll take care of him. He’ll protect Tony at all costs.
