@lovelykhaleesiii @godrakin @borikenlove @ilikeitbetterangsty @connorsui I think I got my Bucky slores all counted out ;)
Feral. - B. Barnes
Bucky was panicking, sour pheromones leaking from his pores. He was an alpha, technically, but would be entering his first rut after years of chemical castration by Hydra. Rendered him beta. Now it was coming up on him, soon— you could smell that much.
Being one of the few omegas around that offered to help him out, your own powers would ease the inevitable roughness of a feral Alpha. Bucky chose you due to your close friendship, both Hydra superpowered assets. You guys could relate to each other. Although you never had to miss a heat, your handler taking full advantage of your needy state.
Bastard.
Bucky had all the signs of rut coming up; aggression, hypersensitivity, appetite, and smelling up the entire room. Stark had banned Buck to his apartment citing, “It fucking stinks, go wear him out for the love of God.” You had grabbed your clothes and favorite nesting blankets to join the brunette soon after.
Subtle cramps made you shift, the fuckers scent alone would send you into a synced heat. He smelled good, like a woodsy smell, a winter’s day, all that sappy nonsense. Bucky grunted, “What if I hurt you? Like bite your mating gland without meaning it?”
You tapped your neck, nail clicking on an invisible collar. Bucky stopped in his tracks, brows furrowing. “They have guards for that. You can lick and scent all you want but no bitesies Barnes.” He groaned, “Thank god for the future, I guess.” Another cramp hit you, hissing involuntarily at the pain.
Blue eyes flicked to you, him coming close to you. He asked gently, “What’s wrong?” You clenched your teeth and gritted out, “You. Going to send me into heat soon so stop fighting it and worrying.” Bucky’s eyes widened and he gulped, coming to terms with the reality of the situation. Fucking his good friend, you, who he had intensely mooned over for a while now.
The brunette nodded and gestured, “Do you need to nest first? I’m just going to, uh, eat a little more.” You rolled your eyes at his obvious stress eating. He was cutely fluffy now from the transition of Romania to the Avengers compound, trying to adjust. Cramp, ow. Grabbing the blankets you mounded and moulded them to your own liking. Bucky’s scent only made it better, you taking a deep inhale.
You cried out as the first real pang of heat hit you, slick gushing forth, sending you into the nest face first— drooling and whining for Bucky. Usually you used suppressants, hating how submissive and fucking stupid you got, the intense emotions brought up old memories. But not this cycle, waiting for Bucky had you back to stupidtown.
Bucky almost snarled in concern, swallowing down his protein bar and crawling onto the bed. You clawed at your clothes, ripping off the top easily. “Buuuck, help, leggings, stupid!,” you managed. The brunette yanked down your legging and underwear, growling, “Don’t call yourself that— fucking hell!”
Oh. There it was. He’d finally hit it. 
Bucky groaned deeply, taking off his clothes haphazardly, you could hear the ripping and tossing while drooling on a blanket, biting down in agony. You whined, “C’mon Alpha, knot, need it, fill my pussy up!” The normal you cringed on in the inside, but Bucky nodded along. He rasped, “Fuck yes, yes, gonna fill my pretty ‘mega up.”
You could almost purr at Barnes referring you as ‘his’.
Buck’s mismatched hands gripped your hips, sliding an impossibly fat cock between your weeping folds. A shiver wracked your spine, mewing and crying his name at the feeling. He rumbled in that Alpha timbre, “Be a good omega and just take it, make it look easy, please.” By the end of the sentence your sweet Bucky had leaked out some. Turning around to gaze at him he slid in your cunt with a grunt, fangs bared and eyes blazing.
Swollen and fucking hot he speared you fully, stretching and overfilling underused pussy. It had been so long since you’d fucked someone and damn you were glad it was him. Your pussy ached and widened around him, gushing profuse slick. Buck groaned and snapped his hips forward, dragging along everything. He let out a strangled moan, “Fuck, dolly, so goddamn tight. Gonna bl-blow fast.”
“Hurry up and fuck me then!”
A rough smack to your ass had you shutting up with a whimper. Bucky jackhammered your pussy, grunting and gasping, poor thing’s dick probably hurting. His hips smacked into your own, a metal hand pushing at the small of your back for a different angle. You wailed, Bucky cursed and pressed his soft belly to your back, chomping and nosing eagerly at the protected mating gland.
He couldn’t get enough of it, moaning and lapping like a baby alpha fucking his first rut toy. Big hands explored your body, one coming down to toy with your oversensitive clit, making you gush further. The closeness and angle had you whimpering, need forcing you to whine, “Oh, Buck, kiss me, please!”
He blinked dumbly at you, lips swollen from mauling your scent glands. You whimpered, emotions immediately jumping to: oh he hates you, used up omega. The alpha frowned and seized forward clumsily, noses mashing together as he kissed you. He still fucked you raggedly, cock swelling and pulling at your walls.
A pink tongue darted out to claim you, Bucky getting the point and tilting his head for better access to your mouth. He moaned desperately, lips driving across yours wet and messy. You threw back an arm to cradle silky-soft brown hair, fucking back onto that thick cock. “Fuuuck, knot me up baby, need it.” Bucky rasped back, “Yeah?”
“Want it, wan’ your knot, feel s’good,” came the resounding whimper.
Bucky kissed you harder, moaning into your mouth as he fucked deeper, more shallow thrusts than anything now, thick fingers pulling at your clit. He growled, “Omega, so tight— mine.” He shoved your hips flush to him, groaning chest deep and guttural as his knot popped and blew inside. You wailed and scrambled around him, that hot cum painting your insides.
Bucky whined deep in his chest, gasping against you, holding squirming hips still as he filled you up. The Alpha lapped and scented you further, murmuring dazedly, “Won’t be able to smell like another alpha again. Never.” His fingers dug into the softness of your hips, locked in now. You panted and shoved your face into the blankets, overwhelmed.
“Jus’ move to the side,” you said quietly. He gently, so very gently, eased the pair of you to the side. The knot pulled a bit, making both of you hiss. Now spooned in the fucked up nest, Bucky seemed to be dozing off, nose shoved into your mating gland, puffing softly. He slung an arm around you, making sure his entire body was plastered to your own.
Some alphas were clingy like that. Not many. Heat abated by Bucky’s knot— your mind inevitably cleared up. Emotions and old thoughts swirled in your brain. Sometimes you’d have to go through heat with a random elite of the world, them getting a present with the inhuman omega. Once you’d been through the humiliation of being used they’d dump you off with your handler, Sitwell.
He made sure to let you know you were nothing but a whore for Hydra. Used to the point where you were nothing but an easy fuck. “No self-respecting alpha would mate you,” he’d tut while inside you. Your chest clenched up, stupid stupid stupid emotions making your eyes burn.
In the same horrid voice as Jasper your mind hissed. Bucky wouldn’t want you. He knew you were easy and used to ruts. You couldn’t wash off the years of filth and scars on your nape. The great Bucky Barnes would get through this first rut and go find a more demure, self-respecting omega. Hot tears pricked at your eyes, chest beginning to heave.
Bucky’s hand came up quickly, cupping your cheek to get a look. His thick brows furrowed at your likely pitiful expression. “What’s wrong sweetheart? Woke me up when ya’ soured, you hurting?” His concerned expression made you cry harder— chest aching for this to never end. The alpha tightened himself to you, a big thumb wiping your tears. His sculpted lips pulled into a frown.
“I-it’s stupid, been a long time for me too, sorry,” you apologized.
He didn’t seem phased, concern wafting off him in waves. The former assassin practically cooed, “Hey now, seriously, what’s wrong? Spit it out baby, I know you better than that.” You stared into dead serious eyes, knowing deep down Buck would win this contest. Mouth gaping in horror you had no clue how to respond.
“C’mon ‘mega, breaking a man’s heart,” he begged soft and sweet.
Turning away from his gaze, Buck’s hand gently pulled you back with a huff. Taking a deep breath you rambled manically, “I stopped my heats after getting out of Hydra. It brings back…stuff. But I wanted to be there for you and I know I’m an easy option and all, I mean being the pass around for whatever need obviously I know how to handle Alphas.” A titanium thumb in your mouth had you rendered mute with a sudden squeak.
His face softened, pheromones swelling and making you feel woozy. Strong fucking Alpha. The anxiety in your chest abated from the scent. He asked, “Do you really think I’d care about your past?” You shrugged lightly, unsure. Blue eyes turned hard, “Give me a list and if they ain’t dead I’ll personally go castrate them.” Bucky took a deep inhale of you again, relaxing some.
“Look at me.”
You peeped nervously.
“When you offered to help I thought my dreams were coming true,” he pecked your temple, “You’re the only one I want, was gonna tough it out if the only girl I care about didn’t volunteer.” You smacked a big shoulder in shock, squeaking, “No- no you’re lying- this is a joke.” Bucky shoved his knot a fraction deeper inside of you, still swollen to hell.
He deadpanned, “Does this seem like a joke to you? I wish the damn thing would deflate so I can fuck your pretty self already. Been lovin’ you for awhile now.”
Whimpering in desire you clenched down involuntarily, Bucky’s eyes rolling back with a groan. He kissed you again, breathlessly laughing, “I thought you’d think I’m too crazy, overweight, and a load of baggage.” Smooching him back you shook your head to declare, “No, no, you’re perfect as is. This is perfect. Don’t want it to end. Love you too.”
“It doesn’t have to, babydoll,” he cooed into your lips.
After confessing one’s feelings, fucking your official Alpha was much more intense. You’d talked it out with him waiting on the knot to deflate, both of you self-conscious balls of anxiety causing the miscommunication. In full, fuck Hydra with a fiery sword.
You’d grown more heat dazed first, losing any touch to speak normally, writhing around. Buck played with your clit until you’d cum two times, chanting his name like a litany. He was goading you on with a smirk the entire time, cocky as hell now, “Yeah, that’s it, squirt for your fuckin’ Alpha.” Or he’d groan in your ear, “Good girlll, yeah, smell so sweet.”
His knot finally went down and now half crazed you rutted back on Bucky’s cock with hoarse shouts, biting into a blanket. He met you eagerly, slapping your ass and talking non-stop. The brunette moaned, “Goddamn baby, fucking ah, sh-shit!” He nudged thick thighs inside your own, using strong hands to pull you onto him. The whole place smelled of sex pheromones.
“Gonna be my big Alpha and breed me up?,” you teased deliriously, not even sure where this came from.
Bucky rumbled deep in his chest, one of those possessive hands pulling you upright to lock around a slim throat. He rasped in your ear, hot breath puffing, “I’ll fuckin’ give you some pups, s’that what you want?” His hips stuttered, cock beginning to swell again as you wailed. Please please please.
“Make you mine for good,” he nipped at the covered mating gland again, “I’d kill anyone who’d take my precious omega away from me, killing anyone who hurt you, mhm.” You turned your head to kiss his swollen lips, hand digging into his hair as the Alpha dug into you. His soft belly fit perfectly into the arch of your back, hips clapping against your slickened cunt and ass. Your brain purred about how big and perfect he was, a good protector.
Bucky begged suddenly, thrusts sloppy and stilted, “Rip th-that collar off, lemme bite, c’mon love— only one I want, make you a mama.” His lips insistently kissed, hands almost frantically grasping you. A bolt of heady arousal spiked up your belly, the need to be claimed and mated taking over. Bucky as yours sealed with his pretty white teeth, you dripped more at the thought.
Pressing the release on the collar you rocketed into a perfect, quiet, blank euphoria at the feeling of Bucky’s teeth piercing your skin. Things felt complete. You sighed in relief, the held on disgust and shame floating away. Coming back to within seconds you snarled and locked onto his pulsing neck, sealing the bite with a lap. Bucky gutturally groaned, knot popping once again, him following you down to the bed.
The pair of you didn’t speak for what felt like an eternity, hoarsely catching breath, living in the moment. Bucky nosed at the now swollen patch on your neck, commenting dopily, “Wonder what Tony’s gonna say when you pop back out with this.” You hummed and squeezed the big arm around your waist.
“He’ll probably stutter for a minute and then act like he knew all along. Steve won’t be surprised.”
Bucky laughed, “He never is.”
His hand splayed out against your stomach, murmuring, “I know you’re on the pill but I meant what I said. Wanna make the ‘mega I love bred up.” You possibly couldn’t get another orgasm out but his gravelly tone and words made you clench. Touching the bond mark you replied, “Wanna make the alpha I love a daddy.”
He groaned, blues rolling up, “Fuck, yes.”
