oikawa should've been drowning in guilt by now.

he was supposed to feel guilty for fantasising about his very best friend's little sister, for nearly fucking her in his car, for thinking about her all day.

he was supposed to feel guilty that he was sneaking into a house that had essentially been his second home for a major part of his life.

and he would've felt guilty. he would've, if it hadn't felt so damn right.

everything about her felt right. the way she kissed him, the way she bickered with him, the way she used his name in sentences frequently.

there was no doubt that despite not being around, he always had and always would care about her. but this was more than that. this was more than just... caring about her.

he felt blindsided by it.

"tooru, you're gonna fall if you don't pay attention", her voice made him snap out of his thoughts and he realised he still hadn't fully made it into her balcony.

"fuck-", he swung his leg over the platform to make it into her room, holding her hand as she hurriedly led him inside.

come to think of it, he'd hardly ever been in her room. he hung out in hajime's room or downstairs most of the time back in the day.

but he didn't have time to give it much thought because of that dress that she was wearing. god, was she trying to kill him?

"you look...", he was at a loss for words as he blatantly checked her out.

she was smiling. he always thought she had a pretty smile.

"so what are you doing here?"

warnings: face-fucking, degradation

she walked towards him slowly, pushing him gently till he was backed up against the wall. his lips parted when his back hit the cold wall behind him.

"hello to you too", he whispered, pecking her lips softly. he found himself confused by the way his heart was beating at a more accelerated pace than usual.

"this isn't just attraction, is it?"

her lips tasted kinda sweet and he couldn't put his finger on what it actually was but he loved it.

his hands were placed on her waist, feeling the thin fabric of her dress. he repressed the urge to rip the whole thing off of her.

"hmm", she went back in for another lazy kiss, hand resting against his jaw.

"you been drinking?", he asked in between kisses, breathing deeply.

"a bit, but i'll remember this just fine"

familiar. despite the fact that they'd been physical only a couple of times, the whole unspoken, label-less, ordeal felt familiar and oddly comforting.

the first time they did anything, she felt bold. the second time, nervous. and now, she simply felt comfortable.

the fact that her heart was still beating loudly in her ears gave her a hint of how easily oikawa tooru could hurt her again but she ignored it.

her thoughts were interrupted when oikawa became more assertive, pushing his tongue into her mouth and massaging hers with it. his hand was already reaching under her dress to grab her ass, humming in appreciation.

she became hyper aware of the situation they were in currently. he was in her childhood bedroom while her brother was asleep just down the hall, her parents were hopefully asleep downstairs and his hands were reaching for the waistband of her underwear like he couldn't care less.

more importantly, the door... was it even...

"oh shit...", she breathed, pulling away from him quickly to go lock the door.

what if someone had walked in?!?!

oikawa was clearly scared of being found out too. guilty? no. scared? yes, he had seen how hard hajime could punch.

but she was back to him in a flash, grabbing the collar of his t-shirt to pull him back to kiss him a bit more roughly. he let out a soft, surprised noise at the move but eased into it, more turned on than he'd like to admit by her taking the lead.

"y/n... fuck i-", he gasped as she bit into the soft skin of his neck, sucking to leave marks. she really could care less about the excuses he was going to make for them. "we need to be quiet"

he would've never anticipated that she would look straight at him, watching him get flustered with choked gasps as she palmed at his boner.

"i think you mean, you need to be quiet"

her fingers hooked around the waistband of his sweatpants, pulling it down as she got on her fucking knees for him.

if oikawa wasn't careful, he'd probably bust in like ten seconds at the sight alone. he looked down at her, tucking her hair behind her ear as she pulled his boxers down just enough to pull out his cock.

she was right. he did need to be quiet. but she was making that absolutely impossible.

she wrapped her fingers around the base, licking the tip. he gasped, holding back her hair for her as she looked up at him.

he was big like she'd imagined. not too thick, but pretty long and the length grew a little as she began to jerk him off slowly.

hearing him lose his composure because of her gave her more satisfaction than she thought it would. she brought her other hand in between her legs, fingers brushing over her skimpy excuse for underwear.

oikawa was struggling. he was usually pretty vocal, so this felt like torture for him. but how could he ever complain, especially when she looked like that?

on her knees, trying to fully fit his cock into her mouth as she began to suck him off. he had a full view of her cleavage and her ass looked amazing in that dress.

but what actually drove him insane was that she was getting off from it. she was turned on just from giving him head.

quite frankly, how could he complain when it felt like this.

he'd been sucked off before. several times. but this... why did everything feel better when she did it?

"f-fuck-", he threw his head back, panting and gasping from how close he felt

and she was about to slow down just a little to tease him but he seemed to have caught on to that, because he grabbed the back of her head.

she moaned at the desperation in the action, fingers slipping right into her underwear for him to see.

tooru was holding her head still now, shoving his cock down her throat and watching the show she was giving him through half lidded eyes. there was a knot in his stomach, rising steadily.

"fuck, s-such a good girl", he groaned, trying to control his volume, watching tears prick her eyes as he fucked her face. she moaned at the praise, thighs parting more to give him a glimpse of how wet he made her.

that was it for him. he grabbed harder at her hair, thrusting into her mouth roughly a few more times before releasing inside.

she swallowed quickly because the taste was sort of bitter, pretty pleased with herself.

his breaths were heavy, and he could only be thankful that he didn't say as much as he wanted to or he would've woken his best friend up.

she was too nonchalant for his liking, looking up at him innocently again.

"looks like you can't be quiet, tooru"

he grabbed her arms to lift her up, pushing her down on the bed, eyes overflowing with the desire to rip her little black dress off her.

he smirked, sweat glistening on his face from how flustered she had just made him. he leaned in, hovering over her with eyes that said something along the lines of 'i'll ruin you'

it wasn't much help that her eyes bore a look that invited him to ruin her as much as he liked.

she laid back, feeling the mattress of her bed dip with his weight as he joined her. his lips never met hers but his fingers did.

he caressed her cheek with the palm of his hand, expression turning hard as his thumb swiped her bottom lip. his index finger subsequently pressed at her lips, as if to tell her to be quiet.

and then he fit his index finger between her lips, pressing down on her tongue gently.

"let me show you what happens when you run your mouth, doll"

the finger was covered in saliva when he retracted it, and he looked satisfied when he brought the same hand between her legs, shifting her underwear to the side.

he jerked the finger inside her, earning a soft yelp from her.

"quiet", he cooed, pushing it deeper inside of her, "don't want our dear iwa-chan finding out, do we?"

the thought made her mind panic for a second and she threw her head back, covering her mouth with her hand.

"oh, come on", he pouted, inserting another finger carefully as he spoke in his honey coated voice, "that's cheating, y/n-chan"

her muffled voice got a bit more high pitched at his frustrating, teasing words. even more so when he began fucking her with both fingers.

"you're so fucking cute", he leaned in, kissing along the slope of her neck sloppily before slightly nipping at her earlobe, "but you'd look so much cuter stuffed full with my cock"

this was new. she didn't know his demeanour could be so degrading. and she didn't know she would like it so much.

he pushed his fingers into her over and over, reaching where her own fingers usually couldn't. he drank in her expression and her trembling legs with utmost pleasure.

his other hand was exploring her entire body.

it ran up the inner side of her thigh to spread her legs apart. then to her hip, squeezing it to make her gasp. then to the strap of her dress, to pull it down and reveal her tits. then to her throat, to choke her gently enough for her to lose her mind.

and then he took the hand that was covering her mouth, and pinned it above her head.

"t-to- ahh!- please", she exclaimed softly, surprised by the sadism in the action

there was an increase in the volume filling the room, and if someone was even slightly awake, they were sure to hear her. she was hoping nobody was, or that they couldn't recognise her voice because it really was shameful.

oikawa took some pity on her, helping her dull her sounds by smashing his lips onto hers when her orgasm was about to hit.

he kissed her deeply, tongue massaging hers as her legs trembled and he felt her panties grow wetter from her release.

she was clinging to him, face buried in his neck from the unexpected intensity of the orgasm. his hand that was pinning hers came to intertwine their fingers tightly.

the whole position was causing his stomach to do backflips and his heart to beat louder. but he barely noticed it over the unadulterated desperation to feel his cock inside her.

"we're not done yet, sweetheart", he whispered, hands gripping her hips to grind them against his erection.

"i should hope so", she whispered back, making his cock harder still. as if that was even possible.

she pulled away, leaning to kiss him again.

he was in an absolute hurry when he searched around the pocket of his sweatpants to find the condom he'd carried with him. he slipped it on pretty smoothly though, as if he'd done it a hundred times before.

her fingers were fumbling at his t-shirt as she pulled it off him, all ready to do what she'd dreamed of for the last week.

he gripped her calf, guiding her leg to be put over his shoulder so he had a better view of her cunt. his hand guided his cock to it, running the tip over her clit to receive a few moans from her.

she clearly felt sensitive from her orgasm, which only seemed to egg him on more.

but it was his turn to be enormously affected when he finally pushed the tip in.

"shit, f-fuck", he was moaning at how warm and tight it felt, "relax a little"

he hissed when he felt her hide her face in his neck again, biting into the skin to drown out her sounds. because it felt overwhelming.

she obeyed his command, trying to adjust to his size as he pulled out a little before pushing in about half his length.

"yes, just like that, fuck-", he moaned, losing the slightest bit of control and slamming the rest of his length inside.

she moaned loudly, nails digging into his back muscles. his sounds were low and breathy. she thought she could cum if he moved even a little more.

it also stung as she tried to adjust, grateful that he was taking it slow.

he began moving cautiously, as if testing the waters or trying not to finish too fast.

the only sounds he could make out from her were indistinct cries of his name. tears were pricking her eyes again by his size.

shivers were running down her spine. pleasure was washing all over her body, concentrating at one spot in her stomach as he began thrusting deeper and harder.

"yes, tooru, fuck- don't fucking stop", she whimpered softly, overpowered by the sound of her cunt gushing around his cock to coat it in slick

the buildup to this moment was surprisingly prolonged, and the two had fantasised about each other enough that they weren't gonna last very long now that it was actually happening.

"yes, yes f-feels so- ahhh- perfect", he breathed and groaned, abs clenching as he went faster

one of his hands was holding her hip tightly and the other was holding her hand above her head, fingers still intertwined. her other hand was holding onto the sheets.

his whole body felt hot against hers. but she could hardly notice that over the feeling of him rutting into her over and over. harder, deeper, intensity increasing with each thrust.

she looked so pretty to him right now. her face was flushed, lips parted as she called for his name, bare tits were on full display, her dress was bunched up to her waist. a couple of tears were rolling down her face, which, ashamedly so, made him wanna ruin her more.

the sounds she was making were the prettiest though, he thought. especially when she was trying to be quiet.

"i've been- fuck- thinking about this", he added between shallow breaths, leaving small pecks on her lips, "all week- ahh- fuck, i'm close"

there was a knot forming in her stomach when he said it, intensified when he leaned in to hit from a new angle. a jolt of ecstasy was felt between her legs when the tip hit one specific spot inside her.

"there- yes- right there, tooru", she whimpered, bringing him in to press her lips to his again.

oikawa only went rougher on her once he realised she was close as well. he sped up, thrusts going kind of erratic and desperate as he hit the spot again.

her head was thrown back again, and now both his hands were gripping her waist to reach deeper and deeper into her.

and then that was it. she felt a much stronger orgasm hit her, seeing stars. and as if he was holding himself back, he followed right after. she felt the condom fill up slightly as he released into it.

they were both breathing heavily as they came down from the highs.

he leaned in, forehead pressing to hers. he kissed her deeply again. he inhaled sharply when he slowly pulled out of her.

he collapsed on top of her a few seconds later, more from being overwhelmed than exhausted. her shaky fingers were tracing circles into his back muscles.

everything felt perfect for a moment.
