Work Text:
Most of their time spent together went similarly to this - Hinata sitting at his desk, working diligently on getting through the stacks of homework they were given every weekend, Natsumi sprawled out on his bed as if she thought she owned it, watching some third-rate yakuza drama and complaining loudly about every inaccuracy while he tried to drown out the noise to focus.
“Hey! Are you even listening? Don’t you think it’s bullshit! This guy just took out his target in the middle of a crowded fucking street! No planning or nothing, and he still didn’t get caught! If we did shit like that-”
“Trying to work, Natsumi.” The words in front of him felt like they didn’t even make any sense anymore, with how many times he’d reread the same paragraph.
He heard her sigh, loud and exaggerated. “You’re always working.”
“Yeah, well, sorry for actually wanting to pass. Not like I can just get my family to threaten the headmaster.”
The pillow hit the back of his head, hard, before he even noticed she’d thrown it. “Fuck you! I would never.” He sighed, spun the chair around to pick it up off the floor, throwing it back at her. She just laughed, catching it deftly. “But seriously! You need to learn to chill the fuck out sometimes.” She grinned wickedly, the same menacing smile Hinata often saw on her before she made some scathing remark to somebody that would make him want to shrivel up and die out of embarrassment. He knew it was just how she was - how she’d had to become to survive in her family, but it got difficult to defend her sometimes. “Bet’cha jerk off to science lectures instead of porn too.”
He felt his face flush red before he had the chance to hide it, before he could snap back with a taunt of his own. Natsumi’s grin grew wider, and she fell into fits of laughter.
“Oh my god. I’m right, aren’t I? Am I right?”
“No! I just-” It somehow still felt so awkward saying it out loud, talking about things like this even with her, even with what they’d done together already. “I just… don’t, really. Do that. I mean.”
Her laughter tapered off, and was replaced with an oddly contemplative expression. “You’re serious?” He nodded, looking away from her as if it might hide his shame somehow. It wasn’t as if he’d never done it, obviously. But with the constant stress and work the reserve course heaped on them, the hours of studying he had to put in to even manage to keep up with his classmates, it wasn’t as if he had much time or interest in sex. It was different with Natsumi - she took the lead, and he happily followed along - but if it had been left up to him to make the first move, he’d probably still be a virgin.
“Wow, what kind of man are you?”
“A man who would rather not have to drop out of the stupidly expensive school I begged my parents to get me into.” He went to spin the chair back around, but Natsumi was faster, sticking out her foot to keep it in place.
“Nuh-uh. You’ve done enough. Come on.” She patted the empty space on the bed next to her - what little space there even was with how small the cheaply made single bed in his dorm room was, and how she was spreading out her arms and legs all across it.
He rolled his eyes, but figured he hadn’t exactly been getting much done anyway, too exhausted for his mind to even be able to process the information properly. He climbed into bed with her, playfully shoving her off to the side as she laughed. He grimaced at the scene that was currently taking place on the TV - some yakuza guy giving an absolutely cringeworthy monologue about trust and brotherhood to the traitor he was torturing.
“I don’t know how you can watch this crap.”
She just shrugged. “Funny.”
Natsumi swung her leg across Hinata’s, wrapping herself around him to keep him trapped there, head resting against his shoulder as her fingertips trailed across his chest. He tried to focus on the TV, he really did, but the second-hand embarrassment was too great and Natsumi was being awfully distracting as she pinched at his nipple through his shirt, making his breath catch in his throat.
“Sooooooo… you really don’t jerk off, huh?” He wasn’t going to give her the satisfaction of answering the same awkward question twice, not that she seemed to care, busy rubbing circles against his sensitive chest. “You only get to come when I make you. That’s kinda hot.” She pinched again, squeezing it far too hard, and Hinata couldn’t help but gasp.
“Y-yeah, I guess.” It was hard to deny the effect her words and her teasing were having on him, when he was half-hard already. She pressed her thigh up between his legs and his hips pushed back against the pressure involuntarily, groaning. That wicked smile returned to her face, and she stopped abruptly, sitting up on her knees to slip off her pajama shorts along with her underwear.
“We’re- already?”
“Shhhh.” She put a finger to his lips, and he obeyed, deciding not to question her any further as she fiddled with the button of his jeans, slipping them down his hips just enough to expose his cock.
“I have…” she swung a leg over him, straddling his hips, rubbing herself up against him ever so slightly, grinning at the choked sound he made. “...an idea.”
He opened his mouth to question her, because no idea Natsumi had that made her smile like that could possibly be a good thing, but she moved quickly, grabbing hold of his erection and pushing herself down on top of it. His question was lost into a stifled moan of pleasure, mind going blank because he hadn’t expected to be inside her that fast, and hadn’t realised how much he’d needed it until he was. She rode him far too fast, bouncing herself up and down at an impossible pace and he reached out to grab her hips, slow her down, because he was going to end up coming far too quickly at this rate.
She saw him reach for her, grabbed both his wrists and slammed them back down against the bed, holding him in place. Being restrained so completely by her hands holding him down, her thighs keeping his hips pinned to the mattress - he was absolutely helpless, and that really didn’t help restrain his fast-approaching orgasm. Especially as she thrust her hips back against him more wildly than before in her newly secured position, creating friction against every part of his overly-sensitive cock.
“Nnh- Slow- I’m-”
“Are you gonna come for me?” She put on a faux-breathy tone, higher and softer than her usual speaking voice, and god, it really did something to Hinata - a moan slipping out of him before he could stop it, muscles clenching and tightening and-
She stopped, leaving him teetering on the edge, lifted herself up, climbing off him and pulling her discarded shorts back on. Hinata just watched, dumbfounded.
“What?” She didn’t respond, just laid back down next to him, throwing an arm around his waist nonchalantly, but that evil smile never left her face. His cock was still aching, throbbing almost painfully from being denied, but he tried to steady his breathing, calm himself down enough to be able to think coherently.
“Was- was this your idea? Just- leaving me like this?”
She giggled, feigning innocence. “What’s wrong with that? I’ll let you come eventually. Go finish your work.”
“And how am I supposed to even- I can’t focus with-” He groaned, knowing that arguing back was fruitless. “Fine. I’ll just go take care of it myself.”
“No. You won’t.” Her response was instantaneous, and unfortunately, she was right. It was pathetic, but if she told him not to, he wasn’t about to go ahead and do it anyway - even though it was none of her business what he did when he was out of her sight. It wasn’t that he was afraid of her or anything, despite her status. The truth was even more shameful - that obeying her orders regardless of how inconvenient or uncomfortable they were gave him a sick little thrill that he enjoyed far too much.
Sadistic as she was, it was clear that she enjoyed it as much as he did. The promise of “eventually” went unfulfilled for the rest of the day, for days, weeks after. She was more insatiable than before - every moment they got alone together she was teasing him, working him up just to deny him release again and again, like it was a game to her, seeing how long he could bear it. Something about it was awfully addictive - even as he had to sit with his discomfort, his pent-up frustration, as thoughts of her teasing and fucking him right up to the point of climax before stopping crept into his mind at the most inopportune moments.
Hinata had never been so consumed by his own rampant dirty thoughts and desperation, making it hard to focus on anything. She was going to absolutely ruin him.
Somehow, he couldn’t quite bring himself to care enough to put a stop to it.
It was almost a month later when he ended up in her dorm room, brand new restraints attached to the bed that definitely hadn’t been there before. He didn’t ask where she’d got them, didn’t want to think about the possibility that they were supposed to be used for kidnapping or torture as she fastened them around his wrists, keeping his arms secured in place and leaving him completely helpless to whatever she decided to inflict on him. He wondered whether today would be the day she’d give in, finally let him come - but he wasn’t sure he even wanted it anymore. The waiting, anticipation, the torture of being denied release was so much more exciting.
“If you can be really good for me, I might just give you a reward.” She ghosted fingers ever so softly over his exposed cock, already hard and wet in anticipation. Every touch felt heightened now, so much more intense with every day that passed in growing frustration. She drew out her cruel torment as she guided him inside her so slowly, and he squeezed his eyes shut, taking deep breaths to try and stop himself from coming right then and there with how worked up he was already.
“You’d better not come until I say you can.” The implications behind her words hung in the air, that maybe, just maybe, she might finally take mercy on him - but the suspense of not knowing was already far more satisfying than any orgasm could be. She rocked her hips back and forth on top of him, one hand against his chest for balance, the other rubbing at her clit. For all her cruel teasing, all her flippancy, how positively unshakable she sometimes seemed to be, Hinata knew from the way her eyes lit up - fixed on his face as he sunk teeth into his bottom lip hard to hold his arousal back - that she loved seeing him like this.
She kept watching him as he fought against his own body, trying desperately to hold back as the pressure inside him built to unimaginable levels. He had to give himself over to it, let himself writhe and moan and make the most embarrassing sounds just to get any form of relief from it - letting himself feel it, letting his body react the way it wanted to while focusing everything he had on not letting it push him over the edge.
Natsumi just used him to pleasure herself, angling her hips just right, speeding up the movements of her fingers as her breathing grew heavier. Though she stayed quiet, the look on her face gave her away - tinted pink, eyes glazed over with sheer lust as her mouth fell open and Hinata felt her clenching around him so tightly, pressure on every last inch of his sensitive, throbbing cock.
He felt almost like he was floating, or maybe even drowning - waves washing over his face with the sweet respite of air he craved more than anything hanging just inches from him. It was dizzying, mind-bending, being kept on edge for so long, and he almost, almost just gave in as the tight muscle twitched and pulsed around him. He let it out as a scream instead, clenching his restrained fists so hard his fingernails dug into his palms painfully, the sting grounding him, allowing him to hold on to the last thread of his desperation that had been so close to snapping.
Natsumi finally relented, slowing down as she rode out her waning orgasm, smiling in smug satisfaction at taking from him what she refused to give in return. Hinata could still feel his pulse racing, chest heaving with unsteady, irregular breaths - but he couldn’t help but feel absolutely elated at the knowledge that he had done it. He had endured.
She leaned forwards, slipping his cock out of her, and held tightly onto his jaw as she gave him a passionate, possessive kiss.
“Good boy.”
He shivered at the praise - it was such an odd thing to hear from her, all scathing insults and sharp-tongued remarks, but that just made it all the more electrifying, setting all his nerves alight.
“Can I-?” He almost didn’t dare to ask, but the way she stared back at him with a wild look in her eyes told him he had made the right choice.
“Beg.” The harsh, commanding tone came through even with how softly she said it, barely above a whisper that he felt against his skin, her face still inches from his own.
“Please.” Shame, embarrassment, awkwardness all went flying out of the window at the rush of arousal that washed over him. “Please, please, please let me come.” The words just kept coming, feeling so natural somehow. “I’ll do anything- anything you say, anything you want, just please, please, please-” He only cut himself off when he ran out of breath, looking up at Natsumi to see a flash of sharp white teeth, eyes dancing with mischief.
“Maybe later.”
