#aaaaaagghhhhh

oh bucky just couldn’t help it. couldn’t help himself. his hand softly trails over your side, looking at you with the prettiest eyes he could muster. even though you were asleep. you look so peaceful, so pretty. it was like you were in your own world and bucky was fucking loving it. he loves seeing you, period. his eyes trail downwards, to your neck that he wanted to adorn with nothing but his marks, to your shirt that you slept in. it looks comfy. fuck.

his other hand dips under the covers and under the waistband of his boxers, his hand wrapping around his half-hard cock. he feels nasty but god, his imagination is running wild. the hand that was on you moves to your stomach, gently pushing your shirt up — he didn’t care that he bunched it up. his metallic palm pressed to your abdomen, his mouth open in a small ‘o’ shape as he started stroking himself. “mmmhh..” he groans softly, closing his eyes in bliss. his fingers press into the soft skin of your stomach — he can’t take it anymore.

he is so glad you’re sleeping on your side; he doesn’t have to move you. he unabashedly yet slowly pulls your boxers down, now with the assistance of his other hand. it didn’t take him long to free his cock, pressing it against your ass. bucky mutters a small, soft apology, just as he pushes his tip past the tight ring of muscle. as slowly as he possibly could. his real hand was placed on your hip. his movements are unhurried as he guides himself even further, gently, easing in with a groan that rumbles against your skin. “sorry.. sorry, fuck.. you feel so good, baby.. i jus’ can’t help m’self...” he mumbled against the back of your shoulder, voice bordering on whiny. god, he feels like the worst kind of man, but the heat pooling in his stomach keeps him anchored to his sin. the way your walls clench around him instinctively almost makes him collapse against you. his teeth sink into his lower lip as his thrusts stay shallow, slow, deliberate — like he’s trying really hard not to wake you.

his metallic arm slides under you, palm pressing to your stomach. his other hand tightens on your hip, the other one trembling faintly against your skin. “fuck— baby… fuck...” he murmurs shakily, pressing a kiss to your shoulder, then another higher on your neck. his lips part as he keeps them pressed to your flesh. “so fuckin’ warm, so tight… you’re perfect.” he finally bottoms out with painstaking slowness, his body pressed flush to yours now, the hard planes of his chest molding to your back. his cock twitches inside you, and he sucks in a sharp breath through his teeth. his hand leaves your hip to wrap around your cock, giving it a few lazy strokes, thumb teasing the slit. “s-sorry, sweetheart… had to. i’ll make it up to you, promise,” he whispers, voice thick and ragged with need.

when you shift just slightly, bucky’s cock throbs inside you and he muffles a loud groan. he retracts his hips back, leisurely, before pushing back in with the same tempo. he’s driving himself crazy like this, but he can’t wake you. he doesn’t want to. the quiet slick sound of him filling you made his ears burn, but he couldn’t stop. “you’d forgive me for this, right?” he murmured against your ear, lips brushing the shell softly. “you love me… you’d understand i needed you.” his voice cracked a little, his desperation slipping through. “can’t help it, sweetheart.” he rolled his hips a little deeper, the drag of his cock making his knees weak. “you’d let me do this if you were awake, right? take care of you, make you feel good…” he was rambling now, breath coming in short, shaky gasps.

his restraint was slipping with every second he stayed buried inside you. you didn’t stir. you were still so perfectly still, breathing softly, your body warm and pliant against his. it made his head spin. made the guilt gnaw at him — but also made his cock throb harder. “i shouldn’t… fuck, i shouldn’t be doing this,” he muttered, pressing his forehead against your shoulder as his hips rocked forward again, just a little deeper this time. “but you feel so good, baby… so fucking good. i can’t— can’t stop.” the bed creaked softly with his movements, but he didn’t care. he couldn’t stop himself now even if he wanted to. his cock pulsed inside you, his thrusts growing rougher, less careful. his metal arm wrapped tight around your waist, holding you flush against him as he fucked into you harder. “gonna fill you up, baby— fuck, fuck— i’ll be quick, i promise,” he rasped, his forehead slick with sweat as he pressed desperate, open-mouthed kisses to your neck. “jus’… just let me. just need you, need you so bad…”

your body shifted slightly in your sleep, a soft breath leaving your lips. the unconscious squeeze of your walls around him made his vision blur. “oh fuck— ohfuckohfuck—” bucky groaned, his voice breaking into a whine as his hips stuttered, slamming into you harder, faster. “that’s it— oh god, that’s it— fuck, take it for me— take all of it—” with a guttural moan, his cock twitched violently inside you as he spilled himself deep, his release hot and thick as he pressed himself as far as he could go, shaking. his metal arm clutched your body tightly as if you’d vanish if he let go, his breath coming in sharp, ragged gasps. “shit… oh, fuck,” he panted, lips ghosting over your shoulder. “i’m sorry. i’m so fucking sorry… couldn’t help it.”

a faint groan left your throat, your hips twitching slightly as if trying to adjust to the intrusion.

bucky froze.

your voice came out low, groggy, and just a little confused. “...buck?”

his stomach dropped. his heart hammered so loud he thought it’d burst out of his chest. “shit— fuck, baby, i— i didn’t mean to wake you,” he stammered, but his hips betrayed him, giving an instinctual shallow thrust that made both of you gasp. you sucked in a sharp breath, suddenly aware of just how deep he was inside you. “are you— oh my god- you’re…”

“i’m sorry,” bucky whispered desperately, his voice breaking as he pressed frantic kisses to your shoulder. “i couldn’t help it. you were just lying there, all soft and warm and perfect— i needed you so bad, baby.” your body tensed, but before you could speak again, bucky’s hands tightened — one on your stomach, the other gripping your hip —and he pulled almost all the way out before slamming back in. a startled sound caught in your throat as your body jolted forward.

“fuck— i’ll stop if you tell me to,” bucky groaned against your neck, his pace already growing rougher, needier. “but don’t— don’t tell me to stop. please.” your fingers clutched the sheets as his cock dragged against that sensitive spot inside you, over and over, faster now. “jesus, buck— fuck, you’re—”

“say you want it,” he rasped, his tone almost pleading as he slammed into you harder. “say you want me like this.” you moaned softly, hips arching back into him despite yourself. “you’re- such a fucking mess..” that only seemed to push him further over the edge. his pace turned punishing, every thrust sending you forward as his grip on your waist tightened. “yeah? you gonna let me use you, baby? let me fill you again?” your only answer was a broken whimper as your cock twitched in response.

“that’s it,” he whined softly, despite his hips snapping into you. “you’re mine. all mine. gonna fuck you till you can’t think.” his voice was still soft. his hand wrapped around your cock again, stroking you in time with his thrusts as his lips found your neck, sucking harsh marks into your skin.

“take it— take all of me—” bucky groaned softly, his voice raw and wrecked as he drove himself as deep as he could go. “gonna fill you up again. make you feel good.” the angle of his thrusts dragged perfectly against your sweet spot, pulling a soft moan from your lips that made bucky whimper outright. “you like that?” he asked breathlessly, his tone cracking as he kept grinding into you. “you’re gonna make me cum again— fuck, i can’t hold it, can’t—” his cock twitched violently as his hips pressed flush against you, burying himself as deep as he could. “oh god— oh fuck, take it, baby—please, take all of it,” he sobbed softly, warmth flooding you as he came again. even as his release dripped from where you were joined, bucky didn’t stop. his cock barely softened before it started to thicken again, still nestled inside your overstimulated walls. his fingers flexed on your stomach as he whispered against your skin, voice wrecked and broken. “i’m sorry— i know i should stop,” he whimpered, his hips rocking gently even as his thighs trembled. “but i need it so bad, baby. need to stay inside you— please let me, please let me do it again…”

“bucky..”

“baby,” he whispered, voice hoarse and small. “i know.. i know,” he continued as he listened to your groggy response. “i jus’ need to make you feel good, too. please… please let me keep going. one more time— just one more, i promise.”
