Oikawa x

utsui, ushijima's father, who has always liked pretty young things. when iwaizumi hajime comes to study under him, they have fun a couple times, but it's all very casual.

until summer comes, and hajime's best friend comes to visit and utsui is greeted with long lashes, pink lips, and the smallest waist he's ever seen.

"please take care of me," the boy says, and utsui can already feel the beginning of his undoing.

oikawa tooru is a menace. he clings to hajime and follows him around like a puppy, all soft smiles and pretty laughs. it kind of drives utsui crazy, but he is a professional, so he pushes any thoughts he might have aside.

but then one night, he comes out to his living room where the boys were studying, and consequently fell asleep, and oikawa is awake and in his sleep shorts. he flutters his lashes and whines about the heat, and nightmares from being in new places.

utsui offers to let the boy sleep in his bed, totally innocent, of course, until oikawa cuddles him, straddling utsui's thigh, and sighing against the damp skin of his neck.

it's almost impossible for utsui to resist the urge to put his hands on oikawa, to put his hands on his waist and tug him closer, his thin t-shirt rucking up until utsui's arm rests on warm skin.

oikawa bites back a small whimper, muffled as it is, and this is the moment utsui's self control snaps. oikawa was just so bewitching, the little minx, that he could hardly be blamed for it.

he pulls oikawa in for a bruising kiss. he had always considered himself to be a pretty simple man with simple desires, but feeling how small oikawa was compared to him was painfully arousing.

his hands circled oikawa's waist with ease, fingers interlocking over the small of his back. it made moving the boy so easy, giving him complete control over the situation.

it was way more hot than he had been expecting.

oikawa is a little brat, too, but the soft whines he's letting out in his ear and the way his tiny hands grip utsui's shirt like a lifeline is just too addictive.

in no time at all, he's got oikawa face down and ass up, eagerly licking at his hole. he has to stuff three fingers past pretty pink lips so his cries aren't so loud, although he would love to hear those noises unfiltered.

he keeps going, though, until oikawa is loose and gaping from his tongue, and he coats his fingers with lube to stick a few in. making sure he's properly stretched out, because utsui is certainly bigger than anyone oikawa might've taken in the past.

"no condom," oikawa whispers, looking absolutely radiant where he's all flushed with messy hair and bitten lips. "wanna feel you, utsui-san, please."

"alright, pretty boy," utsui says. it's impossible to deny oikawa anything. he reaches forward to tangle their fingers together and his other hand grips oikawa's hip for leverage as he pushes his cock inside.

oikawa wails against the sheets, clenching mindlessly around utsui as he tries to get used to the sensation. utsui tries not to black out from sheer pleasure alone. it really has been too long, just the feeling of warm walls squeezing him is enough to send him over the edge.

but he holds back, because he's only 48, damn it, and he's going to give oikawa the best fuck of his life.

(he's fairly certain that it already is, but utsui's never been cocky enough to say such a thing.)

he pulls back enough that only the tip remains before immediately slamming back inside, and thus sets the brutal pace.

oikawa is crying with every thrust, tears and spit staining the sheets, but he doesn't care. his long legs are kicking out with pleasure, while his free hand holds on for dear life.

"i need you to be quiet, tooru," utsui grunts. "don't want to wake hajime up, do you?"

"utsui-san," oikawa wails, not quiet in the slightest, like the damn brat he is.

utsui huffs, but hunches over until he has oikawa pinned to the sheets by sheer weight alone, his hips driving into oikawa with an intensity that should be illegal.

he bites at oikawa's neck instead, leaving a mark that will stay there for days, always hidden just under his collar. utsui knows he'll be thinking about it for weeks after oikawa is gone.

it should be depressing, knowing such a beautiful angel will be gone from his life after a few weeks, but utsui isn't upset in the slightest. he fully intends on flying oikawa back here at some point just so he can fuck his cute little ass again and again.

the thought is much more arousing than it really should be.

"pretty boy," utsui murmurs, just to see oikawa shiver. "you'll let me fuck you again, won't you?"

"yes, utsui-san!"

"good boy, tooru. i'll make you feel so good."

it's a threat and a promise all at once, because oikawa might be ruined for anybody else now, and if he could, he'd stay here on utsui's cock for the rest of his life.

he screams as utsui slams against his prostate. he goes boneless, helpless to do anything but take what utsui gives him. it isn't much of a hardship, he could stay like this forever.

utsui smooths back some of his hair with a soft coo. "oh, sweetheart," he hums. "too much, huh?"

oikawa's nodding with a pitiful little whine, which is just too cute for words. 's good, utsui-san," he slurs, like he's completely drunk on utsui's cock. it's way more flattering than it probably should be.

he really shouldn't be having sex with a guy almost 30 years younger than him, but he can't help it. oikawa is bewitching in the worst way possible. he wants this to be good for oikawa, to give him something to remember this trip by.

already, he can feel that tell-tale swoop in his stomach. a little early, but they have all night and he really isn't worried. "fuck," he groans, worming his arm under oikawa's waist to get a hand around his neglected cock.

oikawa yelps at the sudden touch, hips bucking, but he can't go anywhere, so it really doesn't matter. "utsui-san!"

"i've got you, angel," he murmurs, pressing a soft kiss to oikawa's neck, right over his hammering pulse. "let go for me, sweetness."

oikawa does so with a silent cry, his hole spasming and fluttering so sweetly around utsui's cock. utsui fucks him through it until oikawa is sobbing from overstimulation. he grinds forward once, twice, until he finally cums, deep inside this pretty boy.

oikawa's little sobs trail into whimpers as utsui finally pulls out. he takes a moment to watch his cum trail out of oikawa's red, puffy hole. utsui wonders if oikawa would let him take a picture, and resolves to ask later.

"you did so well for me, tooru," he whispers, petting oikawa's hair back once more. "get some rest. you can use my shower in the morning."

of course, oikawa falls asleep the second his hands touch his hair, so utsui doubts he heard any of his words. that was alright, though, he doesn't mind. he chuckles fondly as he tucks oikawa into bed.

in the morning, he'll go downstairs and greet hajime and pretend like he didn't fuck his best friend. and, more privately, he can only hope that oikawa will sneak into his room more often on this trip.
