Chapter Text
Bucky scented him, rubbing his face along..well everything. Any part of Steve he could access from his criss cross position he rubbed his face on. Running over some of the same spot multiple times but if it made him happy then Steve didn't call him out on it.
“Sorry that I was around so many omegas, they're less likely to beat me up, y'know” Steve spoke calmly, it wasn't like he had a friend group of omega's, Bucky was still the one person he really hung out with. When he did interact with others, they didn't tend to be other betas or alphas. Not by his choosing of course.
“‘s fine, selfish to say you can't be around them” Bucky mumbled, too distracted with the last bit of scenting. They both knew he was unsettled by the smell of multiple other omegas, this wasn't the first time, but it was the first time he was so bothered by it. Steve wondered if there was a reason for sudden insistence for him to smell like him. He pulled away, looking at Steve like he could physically see the smell of him marking him. “Dunno what I'm gonna do when you get a girl. She's gonna have to share, I don't think I'll be able to handle you not smelling like me at all”
It was partially a joke. Steve laughed and rubbed Bucky's head affectionately.
“I don't think many girls will have a problem smelling you,” he teased. Presenting as an omega (admittedly late) did not deter women from falling for him. He was still just as much as a ladies man, if not more. They liked how sweet he was and how submissive he could be, though no one's yet to see him in bed. Going dancing with him or on small dates like a fair was more than enough to see his soft side. Besides, Steve doubted there were any dames who liked Steve but not Bucky.
If there were any who liked Steve at all.
He was drawn out of his overactive thoughts when Bucky trembled, suddenly hunching forward to be withdrawn on himself. He looked sweaty and distant, sick.
Bucky hardly ever got sick. Not even when he'd purposefully stay in close proximity to a flu-ridden Steve.
“Buck, what's wrong?”
“Feel dizzy and hot all of a sudden. Hurts. I don't feel good” he trembled, an arm wrapped around his stomach. Steve brought him a trashcan just in case, they kept one in Steve's room due to his reputation of being sick. Afterwards, he quickly went to get his mom, promising that he'd return quickly. Bucky made a soft noise but he couldn't tell if it was in protest, acknowledgment, or pain.
Sarah had been making soup, it was her day off from the hospital and she was set on making the boys dinner. Sometimes she couldn't do it due to her schedule, Steve was helpless in the kitchen so he either ate little, stayed over at the Barnes, or James would come over and cook them something.
Winifred and her were used to the boys staying together, no matter whose house it was. They were always welcomed.
When she heard a rapid set of steps she thought it was James, coming to inform her that Steve was once again sick or injured no doubt.
She was surprised to see her son.
“Something's wrong with Buck, he was scenting and suddenly became hot and dizzy. I dunno if I did something” Steve blurted worriedly before she could say anything. Bucky had finally presented not long ago, Steve was still getting used to being so close to an omega. And even if Bucky wasn't the conventional kind, he still worried he'd do something that'd upset his biology.
Bucky was trembling still in bed when they got there, the trash was left empty but the arm still curled around his stomach. His position was slightly new, leant forward in a position Steve couldn't see himself being comfortable in, with his face buried in one of his pillows. He perked at the sounds of people.
Sarah quickly sat next to him as he sat himself up properly.
“Oh, hon, it's okay. I understand what's happening now. You're going through heat, it's something omegas do eventually.” No one said anything, for different reasons. The reason for Bucky's silence was because he didn't understand what that meant at first. The realization finally drew on him though, he squinted his eyes unsure.
“Like what dogs do?”
Sarah huffed but nodded, “yeah, like dogs. But there's other ways to combat it that's different from them-” Bucky turned red and squirmed out of the motherly hug she had taken him into at the sight of him hurting.
“I don't wanna talk about this!” He sqeaked with embarrassment. He couldn't be the crazy one for not wanting to talk to his best friend's mom, his second mom even, about having sex like a dog. She hushed him confidently.
“I'm a nurse and a mother, I've talked about worse with people I'm close to. And this is important. It doesn't have to be sexual, sometimes just hugging the right person will help, or getting pets, anything physical but nonsexual can work too. Of course it can also be handled alone.” Bucky trembled harder but it lessened up after a second, Steve noticed. He was less red than Bucky, nothing could be more embarrassing than getting spoken to directly about this, but he knew his cheeks were pink from being a witness.
“However it gets dealt with, you're staying here. It's too dangerous for you to go out now, you'll draw attention” she continued, keeping it to herself that she was going to call his mom and let her know her son was going through heat. She knew James would protest but it was important and much less embarrassing to adults as it was to the older teens.
“My smell bad?” He asked shakily, he was close to tears for some reason. He wasn't usually sensitive but clearly his heat changed that.
“It's strong. Even I can smell it” Steve finally chimed in. Bucky groaned in shame as he put his head back into the pillow that wasn't his. He breathed in the scent that wasn't his. His body visibly relaxed after two or three inhales. Whether it was because of the smell or Sarah rubbing comfortingly on his back, wasn't clear, Steve selfishly fantasized about the latter.
It was less of a fantasy it turned out, seeing as Bucky gave in to his internal battle and sat back up, still slightly hunched from pain.
“Can Steve fuck me, please?” He softly asked, pain was evident in his voice but it was mostly shameless. “Sorry, I don't know if it's weird to ask that, I feel like I have to though. Oh- sorry Steve, it might be weird for your mom to know I want you to fuck me. Or I guess weird for me ‘cause now she knows I-” his rambling was cut off by the adult.
“That's something between you and Steve. However you deal with it, it's okay. This is all normal” she reassured and made her way to the door. “If I hear something I shouldn't, I'll just leave”
She was gone before Steve could protest the embarrassing comment.
He was feeling too many emotions, he was starting to get dizzy himself. He was made aware of his needy friend at the suppressed pained noise.
“Buck” Steve's hand went onto his head, which Bucky leaned into panting.
“Please have sex with me, Steve. Please, please, please, it hurts” Steve helped him lay down and as soon as he was straight his hips bucked into the air gently. Desperately. “If you deny me jus’ ‘cause you don't think I want this I'ma be pissed when this is over. It can just be for my heats, you don't have to actually see me sexually, please. You can still have a girl and stuff” he babbled, squeezing his legs and squirming for friction. He had less shame since it was just Steve now but had enough sense not to jerk himself off openly.
“Buck, I-” he didn't want to say no, he wanted this. He had the erection to prove it. There was no excuse to deny him. “Shit, okay, okay. It's going to be okay, I'll help you feel better” he reassured hesitantly. He didn't know how to start. Should they kiss? Bucky seemed too desperate to allow them to go that slow. What about their position? He had too many health issues to be able to thrust into him without running out of breath quickly.
He hadn't noticed Bucky getting up until he was being dragged to the bed. Bucky made all the decisions for him it seemed. Steve got his clothes off before being coaxed into the position Bucky wanted him. Bucky was going to ride him.
“Poor baby, forgot about your own clothes” Steve teased, Bucky had forgotten he was still wearing clothes. With dazey eyes, he managed to shove off his bottoms, they were wet with something that definitely wasn't urine. Which was surprising considering just how soaked they were. His shirt stayed on out of comfort and/or eagerness. “You've got this, it'll feel good soon. I'll make it better”
“Steve, ah, I need you in” he was a panting mess and no stimulation started. He eagerly lined Steve up with him and forced himself down. Despite the rest of his body, Steve wasn't pathetically small. Especially fully hard like he was. Bucky also never had something in him before, so the intrusion was more than enough. The slick he leaked acted as lube for them. Bucky wasn't slow to get himself fully seated but Steve was able to watch the stages of him adjusting. “Feel so good, perfect length. Stevie, you're perfect” he moaned.
Steve couldn't get himself to say anything at first. He was busy trying to stave off an embarrassingly quick orgasm. Bucky’s insistence to get his hips moving didn't make the task easy.
“God, Buck, such a good boy. You're taking it- ah so good” he praised shakily, he had one hand on Bucky's small waist and the other gripped his thigh, he knew Bucky would appreciate the physical contact and encouragement. He loved doing stuff right. Now it went straight to his twitching cock being praised about something so intimate.
The squelching noise in the room was loud, it turned Steve on being able to see where the lewd sound came from.
“Gonna make you cum, Buck. Need you to. You'll feel better” the hand on his thigh went to the neglected bouncing cock between them. Steve stroked him, he was already slippery with pre and the head was a color that implied it had to have been throbbing with need. Steve paid rough attention there.
“Gah! Gonna cum, close Stevie? You can- nng keep fucking me. I need it. Want you to cum” Bucky was barely coherent, quick sentences were all he could manage. He didn't make moans like average porn actors, his were soft and clearly unwanted. Steve didn't see why he tried to stave them off, the sounds made him twitch.
Steve came before him but maybe that was what the omega needed because he came right when enough of the warm liquid filled him. He shuddered and moaned louder, a broken sob. His body milked Steve for more cum that he didn't have. They were breathless, Steve still tried to give him constant praise.
Jumbled sentences of “good boy”s and “you did so good”s were barely heard but appreciated as Bucky idly rocked forward. They both jolted when the overstimulation set in. Steve couldn't bring himself to go again, he watched the way his mostly softened cock twitched and more cum dribbled out of his omega's cock. Bucky’s head was dipped down but Steve could make out enough of his blissed out expression. He seemed almost sleepy with content.
“Don't pull off until you're ready, okay bud?” Steve got a soft nod in response, Bucky trembled with aftershocks, softly whimpering through them.
“Love you”
“Love you too, Bucky” Steve cooed, massaging his thighs affectionately. He shivered under the touch.
He meant what he said but admittedly hadn't expected him to stay seated on his cock for as long as he did. Simply buried to the base, occasionally giving a rock that made them both moan out, Steve inappropriately wondered how good it'd be to be the one fucking into him. Getting ridden was amazing and he'd appreciate doing anything with Bucky, but he wanted to see Bucky under him with his teary light eyes and flushed cheeks while he made him sensitive.
“You're hard again” Bucky clenched down, encouraging his hard-on to grow. Steve blushed and inhaled sharply.
“Sorry, you're just.. amazin’. I love you so much, Buck. Do you want to go again? I can fill you again” he murmured, he finally got that kiss he's been waiting for. Bucky leant forward to kiss him, rocking more prominently. It was clearly overstimulating his sensitive insides but the omega forced himself through it. Steve helped him.
“Taking it so well. This is your first time doll, you're doing so good. So good- for me. Gonna- ah fuck into you one day, top you”
“Ah! Nnm sorry” Bucky came from the words alone. He clenched and shook through the orgasm, cumming on himself. The shirt would have to be thrown out at this point, it was a good thing Bucky kept half his closet here.
“Don't be. You're riding out your heat. You're doing so good. Focus on yourself, baby, that's what we're supposed to be doing”
“Want to make you cum. You're hard”
“I will. You don't have to do much to make that happen” Steve admitted honestly, “prioritize yourself. Don't keep going if it's too much” he'd probably be able to cum from visuals alone, seeing Bucky sitting on his cock was enough to have him edged.
Whimpering, Bucky continued to move, breathing loudly, sounds escaped easier than he wanted.
Like Steve promised, it didn't take much of that for him to cum. Bucky came again at the feeling of being filled. For a moment, he wondered if they'd be an endless loop of this. Bucky didn't seem like he had plans to get off him anytime soon and Steve didn't think he'd be able to stay soft around the clenching filled hole the whole time.
At some point, Bucky must've had a similar thought and slowly pulled off. He hissed in overstimulation, Steve helped him as much as he could. Mostly verbally.
“Good?” Steve asked breathlessly. He tried not to stare too much at the cum that dripped from Bucky or the messy residue over his own tip.
“Very. I- mph, hate that I'm so sensitive. Gonna cum-” Steve looked in time to see that he did in fact spurt a few short ropes. His body couldn't offer much anymore. It was dribbling out of him. The blanket brushing his tip had apparently been too much for his heat ridden body. “-over anything” he finished his sentence sheepishly, slumping against the pillows.
Steve couldn't stop himself from giving into the temptation of running a gentle finger over the tip of Bucky’s consistently leaking cock. It was like he was still cumming, the way he was shaking implied that maybe he was.
He was rewarded with a louder yelp that turned into a whine and a full body jolt.
“Can't-! No more, St’vie” his eyes were half lidded and teary. Steve didn't touch again but watched as the last of the transparent substance dripped out of his cock. He wanted to lick it clean, perhaps another time. “Sarah definitely heard us,” Bucky stated, exhausted.
“You, maybe” Steve teased with a grimace. He didn't want to think about his mom knowing.
