Well this is me trying to get back into writing…been jobless and will be for the next few months 😅 so lets take this time to catch up on some unfinished fics! I do hope you enjoyed this one… please feel free to comment! I’ll be looking into your suggestions as well regarding my previous post

Steve froze as he sat up on the wide luxurious bed he had slept in last night. And for the past few days as he recalled.

 

“Shit…” the super soldier cursed as he felt his face heat up at the memories flooding his head of the nights prior. It had all happened so fast. One minute he was seated next to Tony along side the rest of the avengers, listening to what Nick fury was initiating for the upcoming weeks. The next thing he knew he was sweating and begging Tony to fuck him mercilessly.

 

And fuck him he did. The blond could still feel the alpha’s knot inside him. Throbbing and cumming none stop.

 

Fuck.

 

He couldn’t believe Tony had actually knotted him. Didn’t he care if Steve got pregnant? Steve panicked at just the thought.

 

Would Tony Stark even support him? Help him raise their pup? Or just reject them both and leave Steve to fend for the pup by himself? The blond bit his lower lip at that. The alpha was living his best years as a billionaire bachelor. He’d probably hate Steve for taking all of it away.

 

Maybe there was still time.

 

Steve thought, as he hurriedly got dress and raced through the spacious room with his heart pounding rapidly in his chest. What was Tony thinking?! They weren’t even in a relationship and he had knotted Steve like there was no tomorrow. Cumming deep inside him that the omega could swear he had gotten pregnant the instant Tony spilled in him.

 

Okay, He had to admit the sex was amazing, infact it had been the best mind blowing sex he had ever had. No other alpha had ever dared touch him the way the billionaire brunette did.

 

All the other alpha’s had become weary when it came to physical contact with Captain America. Like he might break them at any point if they accidentally hurt him.

 

Even if that physical contact was for pleasure.

 

That’s why he had been shock when Tony didn’t seem to care how strong or bigger Steve was compared to him. Infact he had rammed inside Steve, the minute the everyone had left the room hurriedly once Stark had started growling at them to leave. It had been the first time Steve had actually felt dominated by an alpha. Felt fulfilled.

 

The thought alone was enough to get the blond omega dripping. His heart thumping as he felt himself wanting to turn around and find the other man who’s scent filled the entire floor. And just be marked by him then and there.

 

No…

 

He needed to find Natasha, ask her about that pill thing that Omega’s take nowadays if they get knotted by an Alpha by mistake. Even though Steve would be thrilled to finally have a baby, he wasn’t so sure the other was. And He’d be damn if he was going to raise a child by himself.

 

“Okay…get to Natasha’s, tell her what happened and then…what the!” Steve gasped as he stumbled backwards at the elevator door suddenly closing and a 2nd, thicker metal door suddenly slamming down on it. What the heck is this? Steve thought as he furrowed his brows.

 

“Sorry…i didn’t expect you to be the fuck em and leave em kind of guy…”

 

Steve instantly turned to lock eyes with the owner of the voice. Blue eyes staring into brown ones. Unfortunately, the blond couldn’t keep his eyes glued towards Tony’s eyes Since the Alpha wasn’t wearing anything.

 

“Tony…i-i’m sorry, i just wanted to make sure that i wasn’t gonna get pregnant..” Steve explained as the billionaire alpha started to walk towards him. His handsome face suddenly looking confused. “What?”

 

Steve felt his face heat up at the way the shorter man was looking at him now. Naked as a god he might add. “Uh…it’s just you know…yo-you knotted me last night, and a few days before that but as well-“

 

“But you told me you wanted me to get you pregnant…” Tony interrupted him with a confused look. Muscles visibly tensing.

 

“W-what?” Steve’s eyes widen in shock. Did he asked Tony that? He couldn’t remember all the details but there were a few faint memories of him wanting Tony to breed him. Shoot. He was in such a panic he didn’t remember anything except getting fucked and knotted real good.

 

“Oh you remember me knotting you but can’t remember how many times you told me to?” Tony said with an arch brow. His alpha fangs showing as his muscles tightened.

 

Fuck, that’s hot. Steve thought as he felt himself start to heat up again. Tony must of sensed this as he seemed to relax a bit.

 

“ you don’t have to worry about anything…if i did infact get you pregnant i’ll take care of the pup.” Tony smiled softly as he stepped closer to where the other was standing. “I’ll take care of you…” And Steve swore he felt his heart was pounding loudly at that. It felt nice to hear that from an alpha. And not just any alpha, Iron man for gosh sakes.

 

“Tony..” Steve began as he watched the handsome genius give him a gentle smile. His scent radiating warmth and assurance into the air. “I can’t…i-im sorry..” Steve apologized with a sincere frown. Earning him a deeper frown in return from the other.

 

With a sigh, he darted his head to the side to try and see if he had anywhere else to exit Tony’s floor. Avoiding the other’s gaze as much as possible. He just couldn’t. He could never do this to Tony, even if he wanted it. Even if he wanted the alpha so badly he could never tie the amazing alpha to him just like that.

 

And just as he was about to turn his back on the billionaire genius, a large ball like metal device had suddenly flown towards him like lightning speed. Instantly splitting into two and snapping at both his wrist. “What the To-“ before Steve could finish his sentence, he yelped as his whole body was suddenly pulled and slammed against a wall. “Tony what the hell?!” Steve snapped as he tried to wiggle free from the contraptions. Why couldn’t he get out of them?

 

“Now you didn’t actually think i didn’t come prepared now did you?” Tony smiled as he walked towards the other avenger, who was now struggling with his wrist above his head. “You look so good like that by the way..just like you did last night.”

 

And Steve couldn’t help but shiver at the way the alpha was now eyeing him with lust filled eyes. Cursing when he realize he was getting wet at the very sight. Tony’s nostrils flared instantly as he licked his lips. “Fuck you smell amazing…just like last night when i fucked you on the bedroom floor before i knotted you in the bed.” Tony breathed as he began tracing his fingers across the omega’s chest.

 

“Tony…please…” Steve begged as his knees began to feel weak due to Tony’s alpha pheromones now raging all over the place. “Steve please, I’d prefer if you called me alpha” The brunette smirked as he leaned against the bigger man. Trapping him in place as he pressed his exposed dick against the other’s clothed one.

 

And God it felt so good. Steve couldn’t help but moan at the friction and jolt of pleasure it caused. “That’s it sweetheart, just feel it…let me pleasure you from now on..” Tony whispered as he unzipped and tugged the other’s pants down, exposing his own throbbing dick. “I’m gonna knot you real good i promise. Give you lots of pups and care for you when you’re swollen and filled with them…”

 

Steve groaned as he felt the alpha’s fingers start to tease his hole all the while their dicks danced against each other.

 

“You’re gonna be such a great mom…and i’ll be a good dad, a better dad than my dad ever was…i’ll fill you up each night and give you and the pups everything…you’ll be my slutty omega…i’ll show you who you belong to…i’ll show everyone who you belong to…” Tony groan as he continued to pressed their dicks against each other, while his other hand had began finger fucking the now trembling blond.

 

“Ah! Fuck…Tony” Steve moaned.

 

“Say Alpha…” Tony hissed as he thrusted his finger harshly.

 

“Ahh!! Alpha! Alpha!” Steve whined as he bit his lip and shut his eyes at the sudden treatment.

 

“What is it babe?” Tony asked as he started licking the other’s collar bone.

 

Steve swallowed as he opened his eyes. Staring directly at the other man.

 

“Please knot me deep and hard…”

 

And with that Tony smiled as he did just that.
