dirtbag older brother! bucky x innocent!reader cw: incest, corruption kink, handjob, blowjob
your dirtbag older brother!bucky has always been the bane of your existence. it's bad enough that nobody wanted to touch you with a ten-foot pole in high school, that same reputation follows you to your freshman year at the same university where he's a senior.
it's not as if you have any problem catching the attention of cute boys you're interested in; in fact, you draw eyes wherever you go with how you always look saccharine sweet. a purity to corrupt.
no, the problem lies in the fact that, once a boy catches wind that dirtbag bucky barnes is your brother, they hightail it out of there. they don't want to end up with a loser's sister or risk catching bucky's fist. as much of a misfit as he is, bucky also has a temper and a protective streak when it comes to his sister who can barely give him the time of day.
some may say he has a bit of a sister complex. you just think he's an asshole.
unfortunately for you, being in the same university means you can't avoid bucky entirely. not when your mom sends you on errands to keep bucky alive.
take today for example. you stand in front of the gross house where he and his friends live. your sharp, pristine heels and your pretty pink mini skirt a direct contrast against the run-down structure with peeling paint, creaky floors, and the unmistakable scent of weed.
you crinkle your nose as you take careful steps up the front porch and knock. there's loud music playing from the inside. god, you hope none of his loser friends are in there too. they always look at you with too much attention. not the kind of attention you want.
when nobody answers, you decide to twist the knob and — of course these dumbasses don't even lock their door. you sigh and walk in. the stench of junk food immediately infiltrates your senses, the banging music is ridiculously deafening.
"bucky!" you try to call out. no answer. nobody even comes to the door. your skin itches with irritation — or perhaps the dirty air, you can't tell.
you want to get out of here. stat. so you stomp your pedicured feet up the stairs to the room with the sign that says BARNES. KEEP OUT! you roll your eyes. is he still in grade school with this immature sign? you bang your fist against the door.
"bucky!"
no response. you're going to murder him. you push open the door, once again unlocked, to find bucky there.
only it isn't just bucky. he's alone, yes, but it's bucky wearing practically nothing. it's bucky with his fist around his cock, the tip peeking out from between his fingers, and his pants shoved down to his ankles.
"jesus christ, buck!" you cry out, slamming the door shut again.
"shit—" you hear from inside. then there's scrambling and stumbling before the door opens again and bucky opens the door with his jeans pulled up, still unbuttoned and his hipbones peeking from above. only a loser like him still hangs his jeans that low. "what the fuck? don't you knock?"
"i did," you grit out, cheeks still warm from what you just saw, and shove the plastic bag in your hands into his. "mom wanted me to pass you medicine."
your mom can't have her poor baby boy sick after bucky mentioned a light sniffle so she armed you with a bagful of meds to pass to your brother.
"great," he spits out. "is that all?"
"a thanks would be nice, dick."
"you interrupted my jack-off, princess. i'm not thanking you for shit."
"you didn't answer!"
"i had my dick in my hands, in case you didn't notice."
"i fucking noticed."
that seems to pique his interest. his ears perk up, a slow smirk curling on your lips when he finally documents the abashed expression on your face.
"yeah? noticed my dick, did you?"
"oh fuck off."
"it's not like it's the first time you've seen a dick, grow up," bucky snaps and that only makes your chest tighten in embarrassment. your lips press together stubbornly as you look away. bucky seems to delight in that further. "or is it? you've never seen a dick before, little sis?"
you throw him a glare. "grow up."
"i have. clearly you haven't. my cute virgin little sister."
"you're so gross."
"you know, if you wanted to see it, you could just ask," bucky smirks, leaning against the doorway.
your lips part. for a second, you almost say yes. it's not because it's bucky, it's pure curiosity. you've never seen it and at the rate you're going with bucky around, you're going to be the only virgin freshman around. all your friends have lost theirs within the first week and — here you are, two months in and not any closer.
"over my dead body."
bucky licks his lips, eyes trailing over you in your tight white tank top that accentuates your waist and your tits, a tantalizing cleavage that peeks from the top hem. your bare legs exposed from where your skirt ends at a dangerously low length.
"quit looking at me like that. you're disgusting."
"well, you're the one who wants to see my dick."
"i never said that!"
"didn't have to, princess. c'mere." before you can protest, bucky's fingers wrap around your wrist to tug you into his room, the door closing fast behind him.
heat spreads all through your neck. "bucky, i don't— no, this isn't right."
"and you're all about what's right, aren't you, baby sis? aren't you just a little bit curious? you don't want to see what a real man's dick look like? not just a peek like earlier, see my full, fat cock."
"a real man? yeah right," you snort.
you're about to argue again, but bucky doesn't give you a chance because then he's shoving his pants down. his cock stands proudly, thick and long, bouncing against his stomach. it's almost... pretty. you hate to say it but it's clean, it's long. the veins run along it in an intricate pattern that almost tempts you to run your tongue along it—
you snap out of it quickly, slapping a hand over your eyes. "bucky!"
his chuckle rumbles through his chest and his hand grabs your hand again to peel it off. "don't be scared. go on. take a look. i can't have people thinking my baby sis is a virgin. what kind of big brother would i be?"
"you're such a pig!"
"yeah, you're telling me you don't like it?"
the words catch in your throat. you can't tell him that, because you'd be lying. and you're anything but a liar. so you swallow thickly and clamp your glossed lips shut.
"that's what i thought," bucky says smugly. "you can look you know. i won't bite. you can even touch it if you want."
"you're so sick. you're my brother."
"and you're a princess," he snips right back with a roll of his eyes. "who better to try this out with than your big brother?"
you wince when bucky begins to direct your hand over to his cock. your hands are warm, palms sweaty from your nervous, beating heart. bucky guides your fingers to wrap around his length and you squeeze your eyes shut as you feel the weight of his cock on your hand. as you do so, bucky releases a guttural groan.
"that's it, sis. touch your brother's cock."
it should stop you. that icky feeling inside of you only festers. it should gross you out, holding your own brother's cock. and it does, but you can't seem to stop yourself. not when bucky starts moving your delicate hand along his length, not when he starts fucking up into your balled fist.
"ah, fuck, sis, that feels so good. your hand's so tiny. so fucking small compared to my cock."
"s'not that small," you mumble, looking away.
bucky's free hand catches your chin, turning you to look at his dick in your hand again. "don't look away, princess. watch me fuck your hand. watch me take your handjob, virginity, hm? never seen a cock before right? look at you now, already jerking one off."
"you're so sick," you say weakly.
"you're just as sick for enjoying this. like brother, like sister."
bucky doesn't relent, his fingers moving on top of your own as more moans spill from his lips. he mutters about how good your soft fingers feel, how he should use your hand from now on to jerk off. because you'd do that for him, wouldn't you? you're his sweet little sister. the good one. you'd take real good care of him.
"bucky," you whine, legs pressing together.
"now that you've had one of these in your hands, want to try it in your mouth?"
you freeze, eyes flaring in panic. "n-no, i don't think i'm ready for that."
"course you are, baby sis. come on." bucky pulls you along to his bed. he seats himself on the edge. "on your knees."
you balk. "are you kidding me? i'm not hurting my knees for you."
"sis, if you don't stop your yapping, i'm gonna fuck your mouth so hard, you're going home with mascara down your face and a bruised throat. pick your poison."
at that, you blanch. bucky yanks you to your knees, your hands landing on his thighs as you come face to face with his cock. it's a lot more intimidating up close. the length of it — "i don't know if i can fit that in my mouth, buck," you whimper.
"yeah, you can, baby. slowly." bucky cups your jaw, his thumb slipping in between your lips to open them. your gloss is sticky on his fingers, but he's more focused on pressing his thumb down on your tongue to open up your jaw further. "fuck, look at this little mouth pussy. bet it's so tight. maybe you can't fit it all in your mouth, but you can try. that's what you're good at, isn't it? good at doing your best."
bucky licks his teeth as he uses one hand to keep your mouth pried open and the other to position his cock at your lips. the sight of his bulbous tip tapping your lips is enough to have him groaning. he resists the urge to thrust into your mouth, instead easing it in gently.
"relax your lips, baby sis. don't need to be so tense. just relax." you slacken your jaw as bucky pushes in slowly. the slow glide of your tongue under his cock has him muttering a quiet fuck. "your mouth feels so good, baby. so fucking hot, so sweet."
his words coax you slowly. "just keep your mouth open. your older brother will do all the work, yeah? tongue down, want it on the underside of my cock. relax your jaw. no teeth." he hisses when he feels the graze of it.
your gaze shoots up to meet his in apology. bucky nearly cums from that look alone. your pretty pink lips wrapped around his cock, stretching around his girth.
"that's it, you're doing so well," he coos, "you can take more." he starts pushing in deeper and deeper. each time he slides in, he goes a little further. until he touches the back of your throat and he's buried to the hilt.
you choke a little but you're stubborn so you steel your nerve and straighten your back with a mouthful of your brother's cock.
fuck. "shit, you look so good, princess. on your knees for me. lips around my fat dick. look at you taking your loser older brother. mouth pussy virginity's gone for me," he chuckles low.
bucky rises to his feet and tangles his fingers in your hair, shoving you down on his cock again and again. this time, you do scramble for purchase. tears prick your eyes as bucky's cock reaches deep into your throat. he likes the sight of it — your tears, your gagged whines, pretty pink nails scratching his thigh.
"that's right. take it like the good girl you are. suck your brother's cock. you're doing so well, baby sis. training you real good for whoever fucks your mouth next. bet you they can't fuck your throat as good as me. next time you want your mouthful, next time you want to taste cock, you come right back here."
you try to shake your head but bucky doesn't let you. he's relentless in his thrusts. his hips stutter when he sees your thighs squeezing together, like your poor pussy's lacking attention and chasing some form of friction. god, bucky imagines spreading those pretty legs on his sheets, burying his nose in between your legs. he'll smell your perfume and taste the sweetness in your cunt.
"f-fuck, little sis, i'm gonna cum. your mouth feels so fucking good. sucking dick like a champ. first time doing this and you've got your big brother cumming in your mouth. you want it, don't you? want me to fill this pretty mouth with my cum?"
once again, you try to deny him but bucky doesn't care. not when he's so close. he can feel his balls full, his dick stiff with need. your mouth is fucking warm, a tight enclosure around his cock. and you with your tears running down your face.
"buck, you in there?"
bucky jerks his hips a little too hard and you choke, gasping a little bit. he shushes you, burying his cock deeper in your mouth.
"yeah, what's up, stevie?"
"we're gonna head to the basement to practice. you ready?"
almost. so fucking close. "gimme a few minutes."
"a few— buck, we got that gig tonight. we have to—"
"i fucking know," he snarls, "just... give me a few. i'll meet you guys downstairs." bucky looks down at you and your panicked eyes. god forbid your princess self gets caught with your brother's cock in your mouth. your reputation surely wouldn't survive that.
maybe it's not such a bad idea. it would alienate you from everyone else. no one else to turn to except for your good older brother bucky. he'll keep you in here, have you practice everything on him. all your first times. bucky wants all of them.
steve mutters his agreement and bucky hears his footsteps disappear down the hall.
bucky groans low and begins earnestly fucking your mouth again. "stevie doesn't even now, he has no idea it's my perfect little sister sucking my cock. my baby sister taking her brother's filthy cock in her pretty mouth. i'm so close, little sis. so fucking close. i'm gonna cum. gonna cum down my sister's throat." his words are the last straw before he's spilling ropes and ropes of cum down your throat.
you whine as the taste hits your tongue. a little bitter, a little sweet, a little bucky. you try to push him off but bucky keeps his hand on the back of your head to make sure you take every last drop of his cum.
"swallow it."
you shake your head, mouth still full.
"fucking swallow it, baby sis. ain't gonna let you go until you do. learn how to pleasure a man properly. you always gotta swallow."
another whine. but you know he means it based on the look in his eyes. so your throat moves as you swallow around his cock, the cum sliding down your throat and into your gut.
that icky feeling returns. the shame settles in fast. bucky smirks.
"good job, little sis. let's do that again sometime."
