Work Text:
“Be good for your father, Peter,” Tony’s ex-wife said. Peter rolled his eyes.
“Of course Mom,” Peter said.
“Petey’s always good for me,” Tony said.
He tugged his son closer and draped his arm over his shoulder. His ex got back in her car and they waved her off. Tony steered Peter into the house.
“I’ve upgraded the security system since you were here last, Pete,” Tony said. “So don’t worry if something happens, I’ll know.”
“Sounds good, Dad,” Peter said.
They went their separate ways, Tony to his lab and Peter to his bedroom. Tony worked for about an hour before checking in on Peter.
“JARVIS, where’s Peter?” Tony asked.
“Peter is in the living room,” the AI replied.
“Pull up the feed for me,” Tony said.
An image appeared on the holoscreen in front of Tony. Peter was sitting on the sofa, playing a video game. Tony swiped the image away and went back to his project.
About once an hour Tony would repeat the process. This was how they spent most of their days. Sometimes Tony would find Peter in his bedroom, and sometimes he’d be in the kitchen.
The days went by and they fell into their routine. This was how they’d been every time Peter came to visit. Tony had his son every summer, and on alternating weekends and holidays. The days slipped by.
“J where’s Peter?” Tony said absently.
“He is in his bedroom, sir,” JARVIS replied.
“Bring up the video,” Tony said.
The image appeared on the holo in front of him and Tony dropped his tool. Peter was changing, and Tony had caught him before he’d put anything on. He immediately swiped his hand, clearing the image. He cleared his throat and picked up his tool again.
Knowing he had invaded Peter’s privacy and caught him at an inappropriate moment didn’t stop Tony from checking in on his son. Every hour he’d ask JARVIS where Peter was and have the video brought up. Most often Peter wouldn’t be doing anything Tony shouldn’t see. He’d found the boy changing a few more times and always closed the screen down.
“J?” Tony asked.
An image appeared on the screen, the AI no longer needing Tony to outright ask. Tony gasped and stumbled back a step. Peter was in the shower, this time. Tony could see him through the clear glass door. As he watched, Peter lathered soap over his tiny breasts. Tony’s breath caught when Peter’s hands moved lower. He couldn’t tear his eyes away. Peter washed himself thoroughly and Tony drank in the sight. When Peter turned off the water Tony shook himself. He swiped the image away and went back to work.
“Hey, Dad!” Peter chirped, bouncing into the kitchen.
“Hey, kiddo,” Tony replied.
His eyes followed Peter around the island, watching his son's ass jiggle in the little skirt he was wearing. Peter lifted onto his toes to grab a cup from the cupboard and Tony’s eyes roved over the lines of his lithe body. His son was beautiful.
Peter filled the glass and twirled around, causing his skirt to fly up and flash a bit of panty. Tony couldn’t take his eyes off the boy. He felt his cock throb and he sucked in a gasp of air.
Fuck.
Without prompting, on the hour, a live video of Peter would appear in front of Tony. He found himself watching the boy often. Peter liked wearing skirts and dresses, and Tony liked seeing him in them. More and more often, Tony found himself growing hard while watching his son.
This time, the live feed showed Peter in the bathroom again. Tony watched him strip off his clothes and turn on the water in the tub. Peter sat on the toilet and his knees were spread apart. Tony zoomed in, looking his fill of the boy.
Once the tub was full, Peter jumped up and turned off the tap. He slipped into the tub and Tony watched him lather up a washcloth. His cock hardened and he started to palm his length through his sweatpants.
He dipped his hand under the waistband of his pants and gripped his cock. When Peter began running the cloth over his body, Tony started to stroke himself, tugging his cock out of his pants. He watched his son run the cloth over his breasts and then down, between his legs. Tony groaned and quickened his pace. Peter wasn’t being sensual, but this act of voyeurism had Tony close to an orgasm embarrassingly fast.
When Peter dipped his head under the water to wash his hair, his chest arced up, putting it on full display. Tony groaned and swiped his thumb over his slit. He collected the precome and dragged it down his length, making his strokes smoother. The motions of his arms caused Peter’s small tits to jiggle and Tony cursed, coming all over his hand.
He was done for.
Tony spent most of his time watching his son. His hand lived in his pants, stroking his cock even when Peter was clothed. He liked to edge himself all day, until Peter would inevitably go to his room to shower or change for bed. Tony liked Peter’s showers the best.
At thirteen, the boy was starting to grow curious about his omega body. Sometimes Tony would find him playing with his little nipples, rolling the buds between his fingers. A few times Tony had been lucky enough to find the boy playing with his little cock. He hadn’t seen the boy delve further down, yet, but he was eagerly anticipating it.
He was always hard whenever Peter was around. He found himself palming his cock when the boy was in the room with him. Sometimes he’d grind his cock up into his hand while his son talked to him about his day - as if Tony hadn’t watched every second of it.
“So then -” Peter was saying now.
Tony nodded, pretending to be engrossed in the story. His hand slid up from his crotch and his fingertips played with the waistband of his sweatpants. He watched Peter’s face as he slid his hand beneath the fabric. He gripped his cock and squeezed, trying to keep the motions of his arm subtle as he began to stroke his cock. Peter kept talking, oblivious to his father’s actions.
Tony’s hand moved faster, bringing himself closer and closer to an orgasm. The thought of coming with his son across the table had him throbbing. He pressed his thumb into his slit and his hips stuttered up. Peter licked his lips and Tony grunted. Unable to hold it back, Tony came, doing his best to remain quiet while Peter prattled on across from him.
After that, Tony found himself with his hand in his pants around Peter more often. If Peter was in the room, Tony’s hand was wrapped around his own prick. He would stroke his cock all day and sometimes he’d come in front of his son. Those were the best ones.
At some point, Tony decided he needed to see Peter nude in person, not just as pixels on a holoscreen. He’d wait until Peter was changing or showering, and “accidentally” walk in on him. Peter would always cover himself but Tony brushed it off.
“Sorry, kiddo,” or “it’s fine, Pete.”
He began to wonder how he could incorporate touches. He started slowly, hugging Peter for longer or kissing him on the cheek. If he had to walk behind Peter he’d trail his hand along the boy's back. Then he would trail it lower, sometimes cupping his asscheeks.
Tony looked at Peter a lot too, and Peter seemed to have noticed his father’s lingering gaze. He never called him out on it, though.
“Hey, Petey,” Tony said.
He slid behind Peter, who was standing at a workbench in the lab, and slid his hands up Peter’s arms. He rested them on Peter’s shoulders for a moment and looked over his shoulder.
Peter started to explain what he was doing, and under the guise of wanting a closer look, Tony pressed closer to his son. His hands slid down Peter’s shoulders, fingers resting on his breasts. He twitched them back and forth a bit, brushing Peter’s nipples. Peter sucked in a breath and Tony pressed closer. His hard cock nestled against the cleft of Peter’s ass.
“Dad?” Peter asked.
“What, baby?” Tony said, feigning nonchalance.
“N-nothing,” Peter stuttered.
Tony hummed and pressed closer for a second, sliding his hands further down the boy’s breasts. Then he stepped back and went back to his own work.
Tony was rapidly becoming obsessed with his son. His work was suffering because all he did was watch Peter. He watched Peter play video games and watch movies. He watched Peter shower. He watched Peter begin to explore his body. He even watched Peter sleep.
It might have been a problem if he didn’t own the company. He didn’t have to work, so he told his employees he was taking the rest of the summer off to spend time with his son. It left him with ample time to ogle his little boy.
One such night, Tony was watching Peter sleep. The boy wore short pajama shorts and a little cami to bed. When Peter moved, the cami pulled down. His entire right breast was exposed and Tony watched as the nipple pebbled to hardness in the cool air. He groaned and squeezed his cock, biting his hip.
Unable to resist, Tony got up and headed to Peter’s bedroom. He pushed the door open and crept inside. Peter lay on his back with the blanket pooled at his waist. Tony reached forward and slid it off the boy. He sat on the side of Peter’s bed and reached out his hand. He hesitated but then cupped the exposed breast.
Peter shifted, pressing his tit into Tony’s hand. Tony took his nipple between two fingers and pinched it lightly. He rolled the nub, marveling at how soft it felt. He slid his hand to Peter’s other breast and tugged the cami down to expose that one as well. Both hands cupped his son's under-developed breasts and his cock throbbed in his pants.
He held Peter for a moment before he wanted more. Tony trailed his hands down Peter’s stomach, his touch feather-light. He brushed his fingers over the waistband of Peter’s shorts, biting his lip. Should he risk it?
“Jarvis, how likely is Peter to wake up?” Tony asked softly.
“Not likely, sir, depending on what happens,” the ai answered in the earbud in Tony’s ear.
Tony hummed and dipped his fingers beneath the fabric of his son's shorts. He curled them and then tugged, pulling the shorts down Peter’s legs. He left them by Peter’s feet and then spread Peter’s knees apart.
His mouth watered at his first look at his son's little cock, nestled above his tiny pussy. His hands gripped Peter’s thighs and he slid them higher, brushing his thumbs along Peter’s labia. He pressed harder, spreading the lips apart.
He glanced up at Peter’s face and asked “J? Status?”
“Still sleeping soundly, sir,” was the response.
Tony nodded and trailed his fingers up. He took Peter’s cocklet between two fingers and began to stroke it. Fuck his baby was so small. Tony pulled his own cock out to compare and let out a low groan. His boy couldn’t compare at all with Tony’s alpha cock.
He stroked his own cock while he stroked his son’s. A deep breath brought the scent of Peter’s slick to Tony’s nose and he moaned lowly. Letting go of Peter’s cocklet he dipped his fingers into his slit, gathering slick. He rubbed his fingers over his son’s hole, watching his face.
Peter shifted again and brought one foot up towards his ass on the bed, but his knee fell to the side. Tony took it as a sign and pressed his finger inside. He got to the second knuckle before he pulled it back out. Peter didn’t make any movement and Tony pressed his finger back in. This time he sank down to the base, cupping Peter’s sex in his hand. He was so fucking warm inside, and slick.
Tony groaned and started to finger his son. All the while he was stroking his own cock. His gaze moved down to watch his finger pistoning in and out of his son’s small body. Even Tony’s fingers were large compared to his boy.
After a moment, when Peter didn’t wake, Tony braved adding another. He crooked the fingers, trying to stimulate Peter’s g-spot. He wondered if he could get the boy to come before he woke up.
Shifting on the bed, Tony bent down, taking Peter’s small cock in his mouth. He groaned at the first taste of his child and flicked his eyes up. Peter moved but he remained asleep. Tony suckled on his cock, continuing to finger the boy. Adding a third finger, Tony moved faster. He was desperate to make his boy come, now. He had to see what Peter looked like falling apart with his first orgasm. And it would be his first. For all his exploration, Peter was too inexperienced to bring himself much pleasure. Tony had watched him play with himself many times, and the boy never came. Tony wanted to be the first to bring him over that precipice.
Small moans issued from Peter’s throat and Tony groaned. Fuck he sounded so sweet. He sucked harder and thrust his fingers more into Peter’s g-spot. He was close, himself. Peter’s eyelids fluttered and his hips started to lift. Tony risked everything to bring Peter over the edge, and it worked. Peter cried out, shaking with his first ever orgasm. Tony worked him through it and then rolled off the bed.
Above him, Peter shifted on the bed, waking up. Tony stroked himself furiously.
“What?” Peter said.
Tony came all over his stomach. He stayed where he was for a long time. Peter moved around on the bed and JARVIS gave Tony a play-by-play of what he was doing.
“He’s putting his shorts back on. He’s getting under the covers. He’s going back to sleep.”
When JARVIS confirmed Peter was sleeping again Tony bolted from the room as quickly but quietly as he could.
“Morning Dad,” Peter said.
“Morning Pete,” Tony said.
“Hey, Dad?” Peter asked. Tony hummed. “Have you ever woken up and your clothes were, well, kind of, off?”
“Off? Oh you mean like you got hot and kicked your shorts off or something? Happens all the time. It’s why I just sleep nude now,” Tony lied.
That had never happened in his life, though he did sleep nude. He was hoping Peter would start to, as well. Peter nodded and went about getting his breakfast.
“I had a weird dream last night,” Peter said.
Tony froze. Peter wasn’t looking at him, though, so Tony forced himself to relax. He bummed, encouraging Peter to go on.
“Yeah, it was so strange. I thought-“ he cut himself off.
“You thought, what, bambino?” Tony asked.
“Well,” Peter prevaricated. He glanced at Tony and then back to his bowl of cereal. “I thought someone was touching me.”
Tony held his breath for a second. “What do you mean?”
“Well, um, I thought I felt someone’s hands, um, inside me. And uh, I woke up, um, feeling good. And really, um, wet,” Peter whispered the last part.
Fuck.
“Sounds like you had a wet dream, kid. You’re at the right age that I’m not surprised,” Tony said.
He kept his face clear, tamping down his guilt. Peter had said it felt good, that had to mean something. He hadn’t hurt his son last night.
“Yeah, you’re right Dad,” Peter said.
Tony hummed. A plan formed in his mind and he began to work out how to put it in place.
It hadn’t been hard to convince Peter to sleep in the nude. After waking up half-naked a few more times, from “wet dreams,” he stopped wearing his pajamas at night. Tony loved watching him sleep and had been developing something that would make his nighttime activities easier.
He got into the habit of having a drink with Peter every night, usually a hot chocolate. It masked the taste of the drug he spiked it with very well. Every night, Peter would stumble into his bedroom and strip. He would then collapse into his bed and pass out.
He waited only long enough for JARVIS to confirm Peter was sound asleep before he entered the bedroom himself. Because of the drug, he was able to play with Peter for a lot longer. He ate Peter out and fingered him to a couple of orgasms, and then he would hover over the boy and jack off. He couldn’t bring himself to fuck his only son. Yet.
But he was more than happy to cover him with his come. When he was finished, he’d clean his boy up, bringing him to another orgasm.
He also started to masturbate more freely in front of Peter during the day. His cock was constantly hard, and it wasn’t uncommon for him to have a tent. He had started wearing loose shorts and spreading his legs wide enough that his cock was visible. Peter had mentioned it only once, and Tony had assured him it was fine.
“Daddy? Why are your shorts sticking up like that?” Peter asked.
“Hmm? Oh, well, Daddy’s cock is hard, sweetheart. It happens around omegas,” Tony answered with a shrug.
“Your- oh,” Peter said and ducked his head.
Tony spread his legs further and he watched Peter’s eyes track the movement. His cock head poked out of the leg of his shorts and Peter sucked in a sharp breath of air. Tony reached down and palmed it and Peter’s eyes followed the movement.
Their dinner being delivered broke the moment and Tony told Peter to grab their food.
He made sure to find any and every opportunity to show Peter his cock after that. Usually, it was through the leg of his shorts, but a few times Peter had seen him coming out of the shower.
Tony had even convinced Peter that it was okay to swim naked together because it was a private pool. He’d stripped his boxers off and dove into the water. When he came up Peter was staring wide-eyed.
“C’mon Pete, it’s fine. Just strip off and jump in. The water feels great against your bare skin," Tony said.
Peter bit his lip and Tony floated onto his back. He was, as usual, hard. He watched Peter follow him for a minute before nodding. Peter stripped out of his tank top and shorts and Tony stared at him until he jumped into the pool.
He swam a few laps and then swam over to his son. Peter was treading water in the corner of the six-foot end of the pool. Tony boxed him in and pressed himself close. His cock rubbed against Peter’s and the boy whimpered.
“Dad?” Peter asked.
Tony smiled and started pretending to do push-ups against Peter.
“What?” Tony asked.
“What are you doing?” Peter asked.
“I’m working out, you’ve never seen someone do push-ups before?” Tony grinned.
He angled his hips so he brushed harder against Peter and the boy shivered. Tony stopped and wrapped Peter in a hug. Peter wrapped his arms and legs around Tony and Tony groaned. Fuck, his son’s naked body was wrapped around him and he wanted nothing more than to sink his cock into him for the first time.
Instead, he kissed Peter’s cheek, then again, moving closer to his mouth. He kissed him a third time but Peter had turned his head and Tony kissed him full on the mouth. Peter squeaked and pulled back, arching his back and pressing his pussy and cock into Tony’s stomach.
Tony released him and went back to swimming laps. Peter stayed where he was and after a while, Tony got out of the pool. He laid on a sun lounger and Peter finally started to swim.
Thinking he was safe because Peter was preoccupied, Tony took hold of his cock and began to stroke it. He watched Peter swim laps and just move around in the pool.
Eventually, Peter flipped to his back and floated along. He spread his legs and Tony groaned. He moved his hand faster and Peter turned to watch him. Tony didn’t stop, couldn’t even if he wanted to. Peter watched Tony masturbate and his lips parted. A soft whimper caught Tony’s ears and he was gone. He came, while his son watched from the pool.
“Dad?” Peter called. “What did you just do?”
“Hmm? Oh, well remember how I said alphas get hard around omegas?” Tony asked, thinking fast. Peter nodded. “Well, when that happens we have to relieve the pressure. That’s what I was doing, baby.”
Peter bit his lip but nodded. He flipped back over and swam more laps.
Since the pool incident, Tony had taken to masturbating in front of Peter more and more. He always made it seem completely normal and Peter never questioned him. Tony had caught Peter mimicking his motions in the “privacy” of his bedroom.
Tony had continued his nightly routine as well. He made Peter come no less than four times every night, and busted at least one nut on the boy as well. It became their new normal, and Tony found himself craving more.
He hadn’t breached the one barrier he wanted most. He had used his hands and tongue on his boy, but the closest his cock had come was that time in the pool. He was nervous that if he took that step he’d never go back.
One night, after he had made Peter come three times with his hands and mouth, Tony leaned over him to jack off. Peter’s pussy was so slick and Tony found himself pressing his clock head into the boy's cocklet.
He rubbed it along the length and moaned at how it felt. He ventured further, dipping into the slit. He pressed his cockhead between Peter’s pussy lips and stroked himself. He moved it up and down inside his son’s vulva and groaned at how big it looked. His baby boy was so small. It didn’t take long for Tony to come, painting Peter’s pussy with his seed.
He leaned down and cleaned him up, wringing another orgasm out of the boy.
Tony began wandering around the house nude, hard cock bobbing between his legs. Peter’s eyes followed him constantly and Tony would throb every time the boy licked his lips.
It was almost Peter’s birthday and he’d been there for about two months. At some point - and Tony didn’t remember how - he’d convinced Peter that he could be naked around the house too.
“It’s just us guys, right Pete?”
Tony now had unrestricted access to seeing his baby boy at all hours of the day. At first, Peter was shy and would close his legs tightly. But the more Tony spread his, the more Peter loosened up. Tony noticed his son often sported his own hard cocklet.
“Aww, look at you,” Tony cooed.
He reached a finger out and feathered it over Peter’s hard cocklet. Peter squeaked and a small drop of pearly precome drooled out of him.
“You know Pete, just like alphas, omega boys get hard too. And you can relieve the pressure the same way,” Tony said in a casual tone.
Peter blushed but nodded.
Tony sat back in his own chair and started to stroke his cock. It took a minute, but finally, Peter reached between his own legs and started to stroke his tiny little cocklet. Peter was much less restrained than Tony and his little moans soon filled the room.
“Have you ever tried to put a finger inside yourself?” Tony asked, again with a casual voice. This is totally normal, nothing wrong with what we’re doing.
“Um, no,” Peter said.
He was still stroking his little cock and Tony remained silent. He’d put the idea out there, the ball was in Peter’s court now.
Tony watched as Peter’s other hand slowly crept down. He shot a glance at his father, who was openly watching the display. Peter bit his lip and reached down. He pressed one small finger inside himself and started to move it in and out.
“You can add more,” Tony mentioned after a minute.
Peter looked back at Tony and nodded. He slid another finger in beside the first and moved them faster.
Tony watched in fascination, still beating his own meat. By now, he knew Peter had brought himself to an orgasm or two by stroking his little cock. He’d seen it on the live feeds. But watching Peter finger his little pussy was almost too much.
An unending stream of cries left Peter as he added a third finger. He stroked his cock faster, lifting his hips to meet his fingers. Tony cooed at the boy who looked over at him. Peter’s eyes dropped to Tony’s cock and he moaned.
“That’s it, baby, make yourself feel good,” Tony cooed.
“Dad!” Peter cried out and came all over his hands.
Tony stroked himself faster until he came, too. They both lay there panting and Tony knew what his next step would be.
Tony started lowering the dosage of the drug he was giving Peter. Every night, he’d give him less and less. He didn’t change anything else about his new routine. He had no idea when the dosage would be low enough for Peter to wake up while Tony was still in with him and the thrill was intoxicating.
A few times, Peter had squirmed under him while Tony was cleaning him up. He hadn’t woken yet, but Tony had seen his eyelids flutter a couple of times.
During the day, the father and son continued to engage in mutual masturbation sessions. Peter often came shouting “dad” or “daddy.”
Tony had already brought Peter to two oral orgasms. He shifted up the bed and spread Peter’s legs a bit more. Situated between them, he grasped his cock in one hand. He swiped his fingers across Peter’s pussy, gathering his son’s slick on his hand. He used it to cost his own cock and leaned down.
Pressing his hips into Peter, Tony started thrusting his cock across his baby boy’s pussy. His much larger alpha cock bumped into Peter’s tiny omega cocklet over and over again. A small whimper came from Peter and Tony looked up at his face. He was still asleep. Tony watched his face and continued to thrust against him.
Peter’s hips started lifting, pressing himself into his father. A low moan came from deep in Peter’s chest and his eyelids fluttered. Tony’s hips stuttered and he watched Peter wake up.
He continued to thrust his hips, fascinated by his son’s face scrunching up. He was so confused and Tony couldn’t help but find it hot as hell. Tony held Peter’s labia over his cock and kept thrusting. Peter’s hips were moving more now and Tony’s cockhead brushed over his opening more than once.
Peter’s eyes fluttered open and his hips thrust up harshly. Tony had been thrusting forward as well and his cock lodged halfway inside his son.
“Ohhhh,” Peter moaned. “Dad?”
“Fuck,” Tony cursed.
Peter’s hips hadn’t stopped gyrating and he was forcing more and more of Tony’s cock inside.
“Dad? What’s happening?” Peter asked.
“Fuck, baby boy, you pulled me in,” Tony grunted.
“I did? You’re- Dad is that your cock? Inside me?” Peter moaned.
“Yeah baby,” Tony said.
Peter’s hips were still moving, sliding Tony in and out of him. Tony groaned and watched in fascination as his cock slid in and out of his son, never going more than halfway.
“Why?” Peter asked.
“Huh?” Tony said, glancing up at Peter.
“Why is your cock inside me, Dad?” Peter asked.
“Oh, well, it wasn’t supposed to be,” Tony said. “You were waking up and you thrust your hips up as I thrust mine down and here we are. You keep moving, baby, this is all you.”
“It is?” Peter said.
His hips stuttered to a stop and he looked down at where his father’s cock was splitting him open.
“Yeah baby,” Tony panted.
The effort to not force his cock as deep as he could into his only child was a lot. He wanted nothing more than to bury his cock in Peter and fuck him until his knot locked them together.
“Oh,” Peter gasped. He wiggled his hips again. “It feels good, Dad. Can you keep moving?”
“Fuck,” Tony breathed.
Peter wanted it. Said it felt good. He couldn’t deny his son anything, and certainly not when Tony wanted it just as badly.
“Yeah, baby. Let Daddy show you how good an alpha cock can make you feel. It’ll be so much better than your little fingers,” Tony said.
Peter whimpered and Tony adjusted their positions. He slid in further and Peter moaned. Tony pulled back and then slid in again, going deeper and deeper each time. Finally, he was hilted inside his son, their hips pressed together.
He took hold of Peter’s hips and pulled out again. Then he thrust back in harshly, pulling a loud cry from his son. That was it, Tony fucked Peter roughly, snapping his hips. He wanted to find out every sound he could pull from the boy.
The room was soon filled with the sounds of flesh slapping together and Peter’s cries. Tony held Peter’s hip with one hand and slid the other up his stomach to his chest. He massaged Peter’s small breast and his son keened.
“Dad! Oh god!” Peter cried.
“Yeah, that’s it, baby. Let Daddy hear those pretty little moans, baby boy,” Tony said.
He had heard Peter during their mutual masturbation but never while he was playing with his boy. The most he could get was a small whimper, usually right before he woke up. The noises he could pull from Peter were music to his ears.
“Dad! Oh, it feels so good! You’re so big,” Peter cried. “You’re right, this is so much better than my fingers, Dad!”
“Yeah, course, it is Petey. Your body was made to take an alpha's cock,” Tony grunted.
“Ah, Dad! I’m gonna come!” Peter cried.
“Fuck, yeah, come on Daddy’s cock, baby,” Tony growled.
Peter keened and Tony snapped his hips harder. Peter’s back arched off the bed and he shook, falling apart on his father’s cock. He cried out and his pussy clamped down on Tony’s cock.
“Daddy!” Peter cried as he came.
Tony growled and pistoned his hips harder. He hadn’t planned to knot his son, but he couldn’t bring himself to stop. He fucked Peter roughly and Peter continued to cry out.
“Gonna knot you, kid,” Tony grunted.
“Oh god, yes! Knot me, Dad, please!” Peter cried. “Want your knot!”
Tony gasped and fucked Peter harder. His knot was catching and he made it three more thrusts before it locked him together with his son. He growled as he sprayed his son’s womb with his brothers and sisters. His hips kept moving, prolonging his orgasm. Peter came again underneath him.
Finally, Tony collapsed on top of his son. They panted together, trying to catch their breath. Almost two months had led to this moment. Tony, buried deep inside his son whom he had given no less than four orgasms that night.
Tony glanced at the clock on Peter’s nightstand and huffed a laugh. In bright red, it said 12:00 AM August 10.
“Happy birthday, Pete.”
