Work Text:
jungkook flushes under jimin’s gaze; the way he just stands there watching him come undone, falling apart with a heaving chest and an aching, untouched cock.
he wants to be good — wants jimin to call him a good bun and let him come, let him release the overwhelming pressure in the pit of his stomach and his full, painful bladder.
“hyung i - i can’t,” he whines, half chub cock dragging against the pillow jimin had given him. it’s all a delicious, torturous heat — and jimin had elected to watch from a chair at the side of jungkook’s bed. “h-hurts.”
he leans back, cock grasped into his palm as his boyfriend grinds his hips into the soft cotton pillow, his little whimpers music to his ears.
“you can, and you will,” jimin replies, his tone not something jungkook can argue against. he’d encouraged jungkook to drink glass after glass of water, smirking every time his tummy inflated with the liquid, with the way jungkook gasped as he pushed down onto his bladder. “don’t you want to be a good bunny, baby? you can hold it, can’t you? until you make hyung come.”
“i - yes, yes sir. make hyung come,” he repeats, the thought itself a drive.
every time he moves, the water sloshes in his stomach, but he moves nonetheless. for jimin, for the relief that will inevitably be earned after.
jungkook shifts so the pillow is beneath him, rolling onto his hands and knees, pretty hole on display in front of jimin. and fuck — jungkook is an absolute vision. pretty pink rim clenching on nothing everytime he fits down against the pillow. it aches just right, rolling a heat into his bladder, onto his cock.
he moans softly, quiet and high, and jimin’s hand moves against his own cock with a squelch. “that’s right, baby. so needy spread out for me, leaking all over hyung’s pillow.”
the praise leaves jungkook shuddering — he can feel searing eyes all over him, drinking in his half naked body, sweating and desperate on a pillow and his hands. he wants to be fucked, to feel jimin’s cock pushing into him — he wants and wants.
he also wants to pee, because every movement is pushing him over the edge, teasing his ability to control himself. he was never so good at it.
“o-oh god,” he whimpers, a little stream of piss making way from his cock, pushing out without his control. it wets the pillow, and he’s so embarassed, so so embarassed, especially when he hears jimin’s sharp inhale of breath.
“did i tell you you could go, jungkook?” jimin asks, cock abandoned so he’s shuffling against the bed, hand grasping against the meat of jungkook’s ass. he whines, the grip tight enough to hurt, and surely leave a bright mark to admire later.
“i-i’m sorry, hyung! please, i-i can’t help — o-oh.”
words are cut when he feels pressure against his cock, jimin’s hands holding it tightly, straining the piss from spilling. he gasps, squirming against the solid grip, bladder screaming now.
“can’t even hold it for hyung,” jimin murmurs, a slap to his ass enunciating his words. “do you think you deserve to go? to come?”
“n-no, i’m sorry, bun s’sorry,” jungkook sniffles, legs squeezing together because fuck, he’s hardening in jimin’s hand, and it’s really not helping to keep it together.
he goes to apologize again — but suddenly there’s pressure all over him again, pressing, pushing, testing. jimin has elected to shuffle until he’s leaning directly over him, body heavy atop his, cock slotting between his ass and hands directly atop his bladder.
“bun is sorry, hm? maybe i should just let you embarass yourself so you learn your lesson,” jimin hums, fingers digging into his stomach, earning a cry from jungkook in response. “baby gonna piss himself right here, all over himself, all over hyung’s clean pillow.”
“oh my —— god,” jungkook manages, eyes fluttering close when jimin releases the steel grip of his cock, pushing down once more — and jungkook inhales as he spills.
wet filth; a hot trickle along his thighs, legs, soaking the sheets, the pillow.
he moans, the pleasure of emptying himself so good he’s rutting into the pillow harder, jimin’s cock dragging along his ass only making the heat more prominent.
“filthy,” jimin murmurs, teeth pulling at the shell of jungkook’s ear. “you aren’t even embarassed, are you baby? love making a mess of yourself.”
“mm,” jungkook murmurs, the hot piss sticking to his thighs everytime he rolls down, cock beginning to properly harden now that the overwhelming need to pee has dissipated. “a mess, bun’s mess.”
jimin pulls jungkook’s hips straight, fingers slicking up jungkook’s little hole with his own piss — and wasting no time in pushing his cock right into a blubbering jungkook. “that’s right, bunny,” he soothes, jungkook’s yelp sounding high in the room, the sudden intrusion burning, filling him so well.
“gonna fuck you so deep,” the elder continues, a tentative thrust given into the heat of jungkook’s tightness, a hiss reverberating from his tongue when the younger clenches from the words. “fuck your messy cunt with your own piss. so slick and hot — but hyung likes you just like this.”
jungkook pushes his hips back until jimin is bottomed out, a low moan slipping from his lips as jimin’s pace picks up. he’s brutal, pounding into his hole, leaving the sound of skin against skin to bounce off the walls.
it’s all so much — the buildup. his body is pushed down into the piss soaked sheets, jimin’s pants evident and harsh against his ear. the visual of jungkook fucked into his own filth is all he needs to spread him wider, a finger gathering more of his piss so he can slip it into his ass, right next to his thick cock.
“oh god, hyung — hyung, so close,” jungkook cries, eyes watering with the extra stretch and fill, with the way jimin’s other hand presses his head into the sheets until his moans are muffled in the fabric.
“come for me, bun,” jimin murmurs. “wanna see you even messier.”
it takes a dozen more thrusts before jungkook is shuddering beneath his hyung, a soft whimper eliciting as he spills milky ropes onto the pillow his cock rests against. he can feel it all begin to stick along his figure, wet, hot and thick. it's surprisingly not uncomfortable -- knowing it's all his own mess.
the clench of his orgasm is a catalyst for jimin’s own release, a wanton groan low in jungkook’s ears as he pulls out, pumping himself twice before painting jungkook’s ass with his seed.
he loved how filthy jungkook looks by the time he’s finished, tears on his cheeks, come and piss soaking through the borrowed t-shirt. a single finger runs along his come, rubs the thick substance into jungkook's pink flushed ass.
“my filthy baby.”
