okay this blurb sat unseen for too long. we all know how much of a curious, nerdy little shit 40s bucky was, right? yeah he was handsome and had game but mf loved nerdy shit
so Howard clocked it, and immediately told him, “do not touch anything in this lab, barnes.” “i didn’t!” “i know the look” and he really should’ve known better bc as soon as he went to a different room to grab supplies, bucky touched crao he shouldn’t, and ended up in the present time, with his present self, the avengers… and you.
and of course he gravitates towards you, cause why wouldn’t he? your bucky is on a mission so he doesn’t see the first couple of times that two-armed-flirt tries to sweeten you up
“what the fuck is this?” present!bucky says when he gets to the common kitchen and sees his younger self eating cereal with you and nat, you giggling at whatever he said.
your smile became ten times brighter, nats eyebrows shot up anticipating the show, and 40s!bucky thought he saw a ghost. “baby!” you beelined towards present!bucky and explained what happened while he was gone: his nerdy ass fucked around and found out, and now tony and bruce were trying to find the right timeline to send him back
present!bucky was sick of his younger self’s shit. he was too smug, too smooth, and too… sweet. “he’s literally you, bucky. just more hair gel and less metal” “i still don’t like the way he’s on you all the time” “okay, old man”
so present!Bucky makes it very known that you’re his and his alone. late at night when he’s got you on your back with his face buried between your thighs licking into you like a man starved, and your gasping, trying to push his head away “bucky, fuck!” and he’s just smirking and humming against you, flattening his tongue and licking from asshole to clit
and in a room not far away, 40s!Bucky tried to sleep, he really really did, but you were moaning so sweet and it’s his name, so he couldn’t really tune it out. his hand was around his cock before he could even think twice honestly, stroking it to the sound of his older self telling you to “take it all, baby, that’s it, such a good girl f’me” and you begging and moaning and your words getting caught in your throat with the hard thrusts that he pictures would make your eyes roll so far into the back of your head you could see your own brain
he comes in his hand to you begging present!bucky to fill you up so much you’re leaking the whole night
he can barely look at either of you the next morning in the lab, and you don’t think much of it but present!bucky clocks it almost immediately
a few days later you think you’re alone. i know. stupid in a tower full of superheroes who can’t mind their own business, but bucky feels so good with his entire weight on top of you, kissing down your body while your head hangs from the edge of the bed facing the door, that it isn’t until he’s biting the inside of your thigh that you open your eyes and see a little shadow of a familiar soldier at the door, looking at you through the slit
you tapped present!Bucky on the shoulder and he looked up at you, “what’s wrong, sweetheart?” and your voice is just shy of sheepish and a little excited “i think we have an audience” and he looks at the door
you’re half expecting him to tell his younger self off, or just slam the door, or just punch himself back into 1943, anything except tell him to come in and close the goddamn door
his head was swimming. what do you mean he got to see you absolutely get wrecked by a version of him that you look at like he hung the stars in the sky just for you? how dare you look at him like you’d die for him in that very instant while he had you bouncing on his cock like he good little- “c’mere” he hears your voice call out from where you are on the bed with present!bucky, left hand in his hair and right hand just reaching out for him, while he stays there frozen on the armchair, eyes glued to where you’re grinding in present!Bucky
“you heard her” his older self’s voice is low and muffled from where he is kissing up your neck, stubble deliciously scratching the delicate skin
and so he goes. he sits next to you both, and you grab his face and kiss him so deep and breathless it makes him dizzy, gasping into his mouth when present!Bucky grabs his hand and puts it over your breast to play with your nipple
“ffuck baby, feels so-“ you moan against his mouth while talking to his older self, bouncing hard on him “so good, please-“
“no no, sweetheart, can’t cum yet, be good” and it shoots right to 40s!bucky’s cock. you like it when he talks to you like that. fuck, you love it. your hand trails down from his face, to his chest, to his stomach under his shirt, and then your nails are starching at the bulge under his sweats
“bucky can i pretty please suck your cock?” you might as well have hit him over the head with a cinder block “please? i need it” and he barely has time to eagerly gulp and nod and your getting off of present!bucky, oly to sink back down with your back facing him, hand reaching out to direct 40s!Bucky to stand in front of you while you pulled his pants down, the bounce of your hips onto his older self never stopping
“can i?” you look up at him so pretty and doe eyed he almost cums on the spot, all he needs to do is nod and you’re licking a thick strip up his cock and engulfing he head in your mouth, up and down, up and down, up and- good god when his older self got his finger on your clit you moaned around him so needy his balls twitched “look so pretty like this, baby, split open on my cock while you got me in your mouth” and your only response was to squeeze your eyes shut and ride harder “needy little holes, needy little slut”
when you came 40s!bucky felt it, he was so close and your whines where bouncing off his dick and back into your mouth, his older self filling you up with a grunt and still hard
“stop” he heard him say, both you and 40s!bucky whined, why why why did he have to say that now? “okay cut it out, you’re both pathetic” he got you off of his cock and motioned for 40s!bucky to lay back on the bed “lay back, let her ride you” and the way your eyes sparkled when he said that had him thinking of other dirty things he could do to you
and so he did, he laid on your pillows, dick twitching with anticipation as your dripping pussy hovered over him as you crawled on top of him. “want me to ride you, sarge?” if this was any other sentence or occasion, you’d think you were talking to an old man in a park with how fucking sticky sweet your voice sounded, even tho it was hoarse from having his cock down your throat
“fuck yes, sweetheart-“ and he had to squeeze his eyes shut when you bottomed out, he had to think of something, anything, to not cum in you right away.
his eyes shot open when he heard you gasp and whine, and get in possibly tight around him. only for him to see his older self, adjusting himself behind you, giving your left cheek a smack that left a metal shaped welt behind, spreading your cheeks with his thumbs “dont act like you don’t live for this” present!bucky spit on his hand and stroked himself, keeping you open with one hand “you love me filling you up in every way” he bit the back of your neck and pushed the tip in, and you pulsed around 40s!bucky again
“y’feel so good” your voice was right in his ear, whispering in a way that was making it really hard for him to not just rut up to you and ruin the entire night. 
present!bucky’s hand was gripping your hip like a vice, making you ride both of them back and forth “fuck,fuck,fuck-oh my god”
“you’re so fucking tight-“ 40s!Bucky felt like he was astral projecting, he felt high on you, drunk on the vision above him and the feeling on him.
“please bucky, please” you were breathless and your brain couldn’t think of any words except begging “which one of us you talking to, angel?” fuck him and his smug face. “you-fuck- both of you” his hand came around your hip to rub your clit
that was music to 40s!Bucky’s ears, gritting his teeth, pounding into you harder “she’s choking my cock, christ —she’s gonna break me.”
“being the idea. she’s living for this. aren’t you, doll? Being ruined ‘til you can’t think?” all you can do is cry out, muffled “yes—yes—love it, please, I need—”
“cmon baby, cum for us” present!bucky bites your neck, spilling into you the same time you clench around both of them, 40s!Bucky’s eyes rolling to the back of his head, his cum mixing with the sticky mess his older self left behind before
