Breeding Kink*
Another one of Tony’s extravagant parties was in the process of dying down. The last few civilian party goers had left, leaving only the Avengers and Avenger-adjacent members chatting amongst themselves.
You were perched on Steve’s lap, only half-listening to the story Bucky and Natasha were recounting about a recent mission. Being a relative lightweight, the few glasses of champaign you were making you feel warm and fuzzy, so you were content to stay snuggled against Steve’s warm body and inhale his intoxicating cologne and natural scent.
You had met Steve through your uncle, Bruce Banner and something between you two had immediately clicked. True to his gentlemanly self, he had taken you on countless dates before he “made love” to you. You had to coax him to be a little rougher with you, but the results were amazing.
Your thoughts wandered to how his long, thick cock drug deliciously against your tight walls, the way his muscles flexed when he manhandled you into position, and how his tender whispers and praises contradicted his brutal thrusts.
Your thighs subconsciously tightened in response to the images playing out in your mind and there was no doubt that the thong you wore under your dress was getting soaked. Steve shifted and his large hand at your waist pressed you harder against him. Biting the inside of your lip, you hid your smirk, as you knew his super senses was detecting your arousal.
Daring to glance up at him, you bit your lip even harder when you noticed his light blue eyes growing darker. With a seemingly innocent shift of your hips, you pressed against his half-hardened cock, causing him to cough to hide his groan.
“You okay there, Cap?” Natasha’s voice caused both of your heads to snap to the red head. Her expression showed concern, but her eyes had that familiar knowing glint to them. She was perched in Bucky’s lap, albeit less snuggly. Bucky didn’t even try to hide his smug, teasing smile.
“Of course,” Steve covered, flashing a practiced smile but also narrowing his eyes at them since they attracted the attention of the whole group, “Just had some spit go down the wrong way.”
Tony opened his mouth, probably to make some sort of inappropriate quip, but Thor’s loud, booming voice cut him off.
“Lady Y/n!” He smiled, raising his glass towards us, “Lady Pepper and I were just talking about her pregnancy and, unfortunately, the Stark child already has an assigned Godfather.”
Tony cut him off with an annoyed sigh, “Again, her name is Morgan, not Stark child.”
Thor waved him off and continued, “As I was saying, I would like to formally offer to be the Godfather of the Rogers child.”
Your jaw dropped and you felt Steve’s body tense against me, but Thor continued with a pointed stare at Tony, “Apparently you have to get the offer in early around here.”
Steve recovered faster than you did to ask, “Uh, the Rogers child?”
Thor nodded, smiling broadly, and gestured between you and Steve, “Yes, I’m certain you two will make good, strong offspring.”
“Do you want to have kids?” Peter innocently asked you, probably confused about Thor’s certainty.
Your eyes widened, as you and Steve had only vaguely talked once about having kids, even though you had been together for years now. It seemed to be a subject that both of you subconsciously avoided. Steve always used condoms and you always got the birth control shot every three months.
But your previously horny state came back full force when thinking of being filled with Steve’s seed. His large loads always filled the condoms completely, sometimes dribbling out.
And besides, having a little mini-Steve, mini-you, or a combination of you both running around wouldn’t be so bad.
“Yes,” You impulsively responded and quickly tried to recover, “But, uh, we – “You risked a glance at Steve, whose pupils had grown ever bigger but had his features schooled in a polite expression, “ – we aren’t currently trying for a baby…or have really talked about it.”
The atmosphere grew slightly awkward, and you heard Thor whispering – yet still impressively loud – to ask Bruce if he had overstepped. Your uncle gave him an exasperated look and rubbed his temples.
“Well, I think we’re going to retire,” Steve declared, helping you up before standing himself, effectively towering over you.
“Yeah, seems like you have a few things to talk about,” Natasha mused, taking another sip from her drink.
The next thing you know, your being hauled to Steve’s room. The door closes behind you, and your body is immediately pressed between the door and his hard body. His mouth is on yours as he grabs your thighs, lifting up as you latch your legs around his waist.
A moan escapes your lips as his large bulge rubs against your barely clothed cunt. Your fingers thread themselves through his blonde hair, your body aching to bring him closer. His hands leave your thighs, smoothing over your ass before trailing up to grasp your breasts, kneading them through the fabric.
You were so lost in the kiss and his subtle grinding into your core that you yelped when he decided to rip your dress down the middle, exposing your chest to his greedy mouth. The flimsy material of your thong followed suit.
“You want my babies, Princess?” His voice was husky against your skin before he sucked a nipple into his mouth, lavishing the bud with his tongue.
You keened in response, pressing your dripping core against his clothed erection, eliciting a low growl from his chest.
“Yes,” Your reply was breathy, “P – please.”
With a groan, he lifted you away from the door, striding across the room and tossing you onto the bed. Your body bounced a few times and you immediately missed the feeling of his body on yours.
Steve has fucked you too many times for you to count, but this time…this time felt different. His usual adoring gaze was replaced by something far more primal as he ripped his button-down shirt off. When he tore off his jeans and boxers, his aching cock finally sprung free.
Your mouth watered at the sight of the red, angry, and leaking tip. You quickly shuffled to get in position for him to fuck your throat, eager to feel the weight on your tongue, but he stopped you.
“No Princess,” He guided you to lay back as he crawled onto the bed with you, “All of my cum is going into your sweet little pussy.”
You bit your lip as he hovered over you, caging you in with his arms, “Are you sure you want this?” There was a glimmer of your usual Steve in his eyes as he searched your face for any hesitation.
In response, you lifted your hips to grind your bare pussy against his hot cock, smearing his precum onto your stomach, earning a hiss from his lips.
“Fuck a baby into me, Captain,” You ordered, trying to sound sexy, but it came off as a breathy whine as your head was swimming with arousal.
Your words flipped a switch and suddenly you were stuffed full of his bare cock as his lips pressed into yours, swallowing your cries as he stretched you. Your nails dug into his back as he set a punishing pace. His tongue explored your mouth before moving down to your neck, sucking and nipping marks.
“Always so tight,” He groaned, his breath hot on your skin, “Fuck. Gonna fill you up.”
He punctuated his words with a particularly hard thrust right against your G-spot, causing you to scream out in pleasure. You could feel the coil in your core tighten with every delicious drag of his cock against your walls, pushing you closer and closer to the precipice.
Steve could feel it to and, as your walls started fluttering around him, he leaned up, sitting back on his knees so he could piston his cock deeper into you. With one hand on your hip, his other smoothed over your stomach. His large, calloused hand against your soft skin sent shivers down your spine.
“Imagine how swollen your stomach will get,” He licked his lips as his eyes were focused on both your stomach and the visible bulge his cock makes as he thrusts into you, “carrying my child.”
His words brought you to the edge, causing you to whimper, “’M cl-close.”
His pupil-blown eyes snapped back up to you, “You ready for your first load, Princess?”
You could only nod your head, not thinking too much about the meaning of his words. His hand slipped down, and he circled his thumb around your aching, swollen clit, picking up the speed of his thrusts.
It was like electricity shot through your body as his simple actions flung you over the edge. Your muscles went rigid as you cried out, your wet walls clamping down hard around him, trying desperately to keep his cock nestled deep inside you.
“F-uck,” He growled, his thrusts growing sloppy as he hunched over your body, “Here it comes.” His body shuddered as he released ropes of cum deep inside of you, painting your quivering walls. He kept fucking you through both of your releases, grabbing your hips to tilt them up as his cum started to seep out.
He was still impossibly hard as his thrusts slowed, but never stopped. Instead, he rutted into you, rolling his hips against yours. You were still twitching through the aftershocks and clutching the sheets beneath you as you quickly became overstimulated.
“Shh,” Steve gently stroked your cheek in response to your whimpers, “That was just one load, Princess. ‘M gonna pump so much more into you. Gotta have you full of my cum so you can grow round with my babies.”
He sounded as drunk off his arousal as you felt. You found yourself nodding, tears slipping down your face as the coil was starting to tighten once more.
Suddenly, he slipped out of you, quickly manhandling you to flip you over on all fours. You sighed as you felt his hot cum pour out of your cunt, only for it to be drawn into a shameless moan as he carefully scooped it from your skin and stuffed it back in your weeping hole.
He entered you again with a determined grunt, pistoning his hips against yours, causing your arms to give out. Your head dropped onto the bed as Steve held your ass up with a bruising grip. The new angle allowed him to hit even deeper spots inside of you and his cock pulsed as he groaned.
Another orgasm was quickly building up inside you. You placed your palms on the bed for leverage and started to fuck yourself back onto his cock, trying desperately to keep up with his pace. It felt like you could feel him in your throat, he was so deep.
“Give it to me, Captain,” You moaned, chasing your high, “Fuck me – ah – breed me!”
“Shit!” He cursed, droplets of his sweat dripping onto your back as he emptied another load into you.
His fingers frantically reached for your clit, but you were already cumming from the sensation of this load being added to the first. You were so full, yet your cunt was determined to drain him dry, eagerly sucking and throbbing against his cock.
You were still reeling from the white, hot pleasure pulsing through your body when he pulled you up, pinning your back flush with his chest as he kept his cock buried in you. You automatically turned your head to capture his lips in a sloppy kiss, moaning as he gently grabbed and tweaked your nipples.
“So good, Princess,” He praised, rubbing your sweaty stomach, “Your gonna be such a good mommy.”
Through the fog in your mind, you smiled innocently, “And you’ll be the best daddy ever.”
He licked his lips as his eyes darkened again, his softening cock now growing hard yet again within you, “Ready for the third load, Princess?”
By the time he emptied himself inside you for the sixth time, you were beyond fucked out. Your body had quickly become completely pliant, and he maneuvered into several positions, always making sure to stuff any of his cum that leaked out back inside.
You felt so full by the time he laid you both down on the bed that you didn’t know if the bulge in your stomach was him or his cum. He kept his cock, now softening, firmly inside you.
“Wouldn’t want any to leak out before it has the chance to take,” He murmured, holding you close against him.
You hummed, feeling the tendrils of sleep pulling at you, but the logical side of your mind was slowly coming back, “You realize that it’ll be another month before my birth control shot wears off right? And…I mean, we probably need to talk more in the morning about actually trying to have a baby.”
“I know,” His hand smoothed over your stomach once again, “But it never hurts to practice.”
He gave you a sleepy smile which you returned, snuggling into him to drift off to sleep.
“And besides,” His voice wafted over you, “Those shots aren’t effective against my sperm, with the serum and all.”
Your eyes shot open as you looked at him, but he was already peacefully asleep, a small grin on his face.
