Work Text:
“You’re really gonna make me review you in chemistry during winter break?” Kuroo asks, face unimpressed, as he sits down next to Kenma. The electric heater of the bedroom kotatsu immediately warms his legs, but he presses his bare feet on Kenma’s shin just before the chill leaves his skin. The high school senior kicks at him under the table.
“Do you want me to pass the entrance exam or not?” Kenma sounds bored as he asks back.
"Would've loved to shut my brain off during my break, thanks." Kuroo does his best to avoid looking at the papers and books on the table. To his misfortune, there are no interesting programs on the TV at the moment, so Kuroo gives up on flicking through the channels. Glancing down, he notes, “Haven't we gone through this before?”
“I answered a practice test yesterday and got a few parts wrong.” Self-consciousness seeps into Kenma's voice. Fingers rubbing at the corners of one of his notebooks. He continues to prod, "Come on, Kuro. Just help me. It's not like winter break is gonna end tomorrow."
Kuroo really only means to tease. It's undeniable to anyone who knows both of them that Kuroo Tetsurou can hardly deny Kozume Kenma anything. Usually, Kenma's the one calling the shots, because Kuroo lets him (or so he says). It's something he's been thinking about lately: making Kenma chase after him. His few attempts have been effective so far, especially after he moved away for university.
The past few months have consisted of Skype calls deep into the night; Kuroo juggling both his own studies and Kenma’s reviewing. No amount of pouting and concerned pleading ever persuaded the older boy to spend his time for himself.
“I can’t have your grades drop just because I’m not there,” Kuroo reasoned on the other side of the call.
“It’s not like they’re your grades. Plus, they’re not going to drop. I’m not entirely hopeless, you know.” With his boyfriend’s eyes trained on his notes, the glare Kenma shot him through the webcam wasn’t received.
“We both know you’d jump right into playing your latest game as soon as you finish your homework, Kenma-kun.” His captain’s-voice a lot more prominent now. He looks up slightly, one brow raised and eyes sharp. “Go get your notes.”
Scoffing, Kenma stood up to get them anyway.
At present, Kuroo decides he’d help out, because of course he will. To make it more interesting though, he might as well try something he’s heard from his university friends and their girlfriends. Kuroo grins, scheming and wide, and says, “I'll teach you, but you have to call me senpai the whole time.”
Kenma's face changes from indifferent to judgemental in record time. Bingooo. It’s something Kuroo always enjoys witnessing. Something he misses causing so often.
“You've been watching too much porn again,” the younger boy accuses.
“Oho? I wasn’t implying anything,” Kuroo fakes a gasp, bringing a hand in front of his mouth as if scandalized. “I am simply an upperclassman that can help with these exercises. Get your head out of the gutter, Kenma-kun.”
“You've tutored me hundreds of other times. Why should I start calling you that now?”
“No particular reason,” Kuroo shrugs, sounding and looking very much like there is a particular reason. Kenma only raises an eyebrow in suspicion. Feeling the sad end of his little stunt, Kuroo resorts to hugging Kenma’s arm, swaying the both of them as he tries again. “Humor me a little, Kenma. The sooner you call me senpai, the faster we can finish your review.”
They stare at each other: Kuroo’s bright gaze unyielding to Kenma’s unimpressed glare. The setter eventually looks away and tsks.
"You're a menace to society," he starts. Kenma sucks in his lower lip to bite at it. It's insanely distracting.
Kuroo thinks that's that. Mission failed. He moves to grab one of the notebooks on the table to see what they'll be working on when Kenma places a hand on top of his. Slender, calloused fingers wrap around his wrist. Quietly and without looking at his face, Kenma says, "Please teach me chemistry, Kuroo… senpai…"
Both of them blush a hot shade of red. If spontaneous human combustion was possible, it would've happened to Kuroo right at that moment. He had been the one to request it but even he couldn't handle how terribly appealing to him that was.
“R-right, of course.” Kuroo clears his throat. He watches Kenma’s hand retract and settle down on his papers again. His own hand now missing Kenma’s warmth, he flips open the notebook. “What kind of senpai would I be if I didn’t help you out, huh?”
“Please stop being weird. Let’s just start,” Kenma delivers stoically before smirking the tiniest amount and following with a sweet, “Senpai, come on.”
“See? You’re into it too, Kenma-kun,” Kuroo chuckles, hiding how much the honorific is actually affecting him. When he gets a glare from his boyfriend, he straightens up and asks, “Okay, which topics do you need to review again?”
Once Kenma points out the mistakes he made during the practice test, both of them get serious about discussing organic compounds and chemical equilibrium. Honorific-use with hidden agendas now forgotten.
They go back and forth. Kuroo explains concepts and formulas, and comes up with practice problems while Kenma asks more questions and answers the exercises on his own. It feels exactly like high school again. They’ve never really cared about seniority in their relationship, but Kuroo feels proud of being able to teach Kenma nonetheless. To have his boyfriend rely on him.
The supposedly short review session stretches out into the night. After dinner, they go right back into it, much to Kenma’s annoyance. Even though this was his own idea, Kuroo makes sure to comment.
While there’s been improvement on the topics Kenma got wrong during his practice test, he messes up on other topics they review too. Kenma’s frustration starts to show itself. He groans and sighs. Creases form on his forehead as he glares at the questions and equations. Kuroo assures the high school senior that it’s only because Kenma’s been studying so many subjects and topics that he’s forgetting some things.
“Nothing practice and repetition can’t improve,” he reminds, much like he did as a captain.
To which Kenma cringes, much like he did during the Nekoma huddle speech. “This sucks. I don’t want to answer anymore.”
“Just a little bit more, okay?” Kuroo finishes the last of another set of ten practice problems and slides it over in front of Kenma. “Then, we can relax all day tomorrow and review math or something.”
Kenma suddenly drops his head on the kotatsu, grumbling at the added work. “We should just be able to absorb information like this,” he says as he shakes his head against the worksheets.
“Kenma, you’ll hurt yourself.” Kuroo pulls Kenma up by his shoulders. His boyfriend is definitely starting to lose it. They have to finish soon and Kuroo believes this is the correct topic to end with.
Kuroo winds an arm around Kenma's waist, hoping the younger will become more pliant from the touch.Touching Kenma in gentle ways usually works to get him to do things he's reluctant about. Tucking a lock of hair behind his ear gets him to eat another few mouthfuls of dinner. Rubbing his back makes him less anxious about talking to new people. Circling a thumb on the back of his hand helps him communicate his feelings more honestly. So Kuroo kisses the side of Kenma's head for good measure before encouraging him, "Just a few more and we're done, okay?"
Though this all seems to backfire and explode in Kuroo's face. The university student's breath hitches as Kenma leans in and firmly touches Kuroo's thigh. "Senpai…" with a bit of a pout he continues, "I'm getting tired."
"Fine, y-you can just answer five out of the ten questions. It'll be quick." Kuroo tries to lean away from Kenma, but the third year keeps following. Another small hand paws at his other thigh. He sends a prayer to whoever is out there that he doesn't get a boner from this, but Kenma seems determined to make it happen.
"If I answer the question correctly, will you give me a kiss?"
Kuroo nervously glances at the sheets of paper on the table. As of now, Kenma has an 80/20 chance of answering correctly. Should he really encourage this behavior right now? It's late and they're both tired. Plus, Kenma's parents are in the room down the hall... But Kenma looks so cute and he's calling him senpai so sweetly too. It dawns on him just now that they haven't kissed since their reunion in this bedroom.
Aaaah, fuck it, Kuroo thinks.
He stops moving away and looks down into Kenma's mischievous eyes. Lowering his voice, he asks, "And what should I do if you don't get it right?"
Kenma stares back at him just as dangerously. "I leave that up to you. I'm sure you already have some ideas, right, Kuroo senpai?"
Fuck. "I'll think about it. Get to work, then."
As Kenma works on the final problems, he leans on Kuroo's side. Seeking warmth or hoping to tease with the closeness, the older man doesn't know, but welcomes it either way. Unlike the previous exercises, Kuroo watches as Kenma goes through each question. There's an obvious deliberate slowness in how he writes and solves. He scribbles, pauses. He writes on the side, pauses. He hums, stares at the page, pauses.
Kuroo is very much aware that this has turned into a game. It's not very hard to assume. This is Kenma after all. He plays by making Kuroo fall into his trap and get what he wants: sex, kisses, and no more studying. Kuroo plays by knowing exactly how Kenma plans him to fall, so that he can come up with a fitting punishment–or reward, it depends on how horny his boyfriend is right now, really.
A perfect solution and answer to the first problem. Tiny computation mistakes for numbers two and three. And completely correct solutions on the last two, but they both have wrong final answers.
“Tsk, we’ve been at this for hours and you still didn’t pass the short exercise?” Kuroo frowns as he says. The disappointment actually sounds believable.
“I still got one of them correct, so,” Kenma pauses to turn towards Kuroo fully. His eyes are rounded and demanding as he pouts his lips ever so slightly. “I get a kiss.”
Kuroo brings a hand up to Kenma’s face, cupping his cheek. He smiles as he rubs his thumb on the smooth skin. The way Kenma leans into the touch, the warmth, feels natural. Kuroo’s smile turns sly before he declares, “Punishment first.” Instantly, his boyfriend frowns. With a pat on the kotatsu, he instructs him before Kenma gets to say anything, “Bend over the table.”
“But— Sen—”
“If you wanted kisses, you should’ve answered correctly, Kenma-kun.” There’s a dark lilt to Kuroo’s tone now and Kenma just melts at the sound of it. His eyes grow softer. His mouth opens the slightest bit in interest. “Now,” he pushes away the papers and books in front of Kenma and continues, “bend over the table.”
Kenma snarls, yet he’s still red in the face. And still does as told.
Slowly, he pushes himself out of the kotatsu and kneels as he plants his forearms on the tabletop. Eyes locked on Kuroo, Kenma pushes his ass up and rests his head on his arms.
“Well, aren’t you comfortable?” Kuroo taunts. Before Kenma could react in any way, a smack sounds in the room. The faint sting under the skin of Kuroo’s palm surfaces at the same rate Kenma’s mouth falls open in shock.
The loud sound sobers Kuroo a little. With the same hand, he rubs at the spot, ready to apologize, except Kenma presses his ass back on his palm. Face hidden behind long blonde hair, the third year rocks himself just a tiny, tiny bit to encourage Kuroo’s hand to move.
“Tsk. Enjoying yourself now? That one must have felt like nothing, then.”
Kuroo pulls down Kenma's sweatpants until the garter sits just above the bend of his knees. His boxers follow and Kenma’s pale skin prickles visibly in the cold. Kuroo coos, tone mocking, “Aww, it must be cold. How about I warm you up, Kenma-kun?”
The same hand rubs at the exposed skin. His rhythm doesn’t let up, not giving Kenma any time to brace himself. He gives it another second before hitting Kenma’s ass.
“Fuck,” Kenma hisses against his arm. He jolts at the impact, the kotatsu pushing forward slightly as well.
“Two more,” Kuroo announces. He strikes again the moment Kenma nods, coloring the other cheek pink, and lands the last one when he hears Kenma whine at the pain. Heat blooms on the skin under Kuroo’s palm and he can’t help but grin at the feeling.
A glance at the schoolwork on the table gives him an idea. The grin stretches, more menacing now, just like on the court. He tucks Kenma’s hair behind his ear before preparing to stand. Even his adorable face is red. The glare he throws at Kuroo ultimately has no effect.
“Go review your notes,” Kuroo instructs with no room for argument. When Kenma moves to sit on his haunches, he tuts as he opens his boyfriend’s closet. “Stay bent over the table.”
“How am I supposed to do both of that?” Kenma questions, annoyed. Except he moves back into position anyway. His body has always been more honest than his mouth.
Head inside the wardrobe, rummaging through Kenma’s piles of clothes, Kuroo replies, “You’re smart. You can figure it out.”
“What are you even—”
“Found it.” Kuroo steps away from the furniture and walks back to where Kenma’s waiting. He wiggles the bottle of lube in his hand, the one Kenma keeps hidden away for… special occasions, as he raises his eyebrows salaciously at the same time. Instead of responding, Kenma huffs and turns his eyes back on his review materials. His upper body is still down on the tabletop, but his arms are stretched out in front of him now, hands holding his notebook. Taunting, Kuroo comments at the sight, “Aww, see! Kenma-kun was able to think it through.”
Back beside Kenma, Kuroo uncaps the bottle and pours a generous amount of lube on two fingers. He watches Kenma’s face, makes sure his eyes are actually moving on the page in front of him. Leaning closer, he whispers against his cool ear, “Make sure you keep reading, okay?” And rubs the pads of his wet fingers around his pucker.
“Fuck! Kuro, it’s cold!” Kenma exclaims, instantly looking back at Kuroo. He tries to get away, pushing his hips closer to the kotatsu. But the university student just places the heel of his palm firmer on Kenma’s lower back, giving his hand good grounding as he continues to tease Kenma’s asshole.
“It’s still senpai for you.” Kuroo tries to fight against the blush rising on his own cheeks at how shameless he sounds. “We’re still studying. Will you keep reading for me, Kenma?”
“Yes, senpai,” he says through gritted teeth. The bound paper crinkles a little as Kenma’s grip tightens on it. He tries so hard to keep the defiance in his eyes. Wants to let Kuroo know that he is not enjoying this, but the fight is hardly there on his face. It’s all soft, melting as Kuroo plays with him. Kenma turns back to his geometry notes as he bites his lip at a swipe of Kuroo’s finger across his entrance. The image makes Kuroo feel drunk with power.
When Kenma flips to the next page, Kuroo eases a finger in. It’s a tight fit and makes Kenma’s toes curl inside his thick socks. Kuroo thinks it’s adorable, so he twists his wrist as he pushes in again. He repeats the motion, coaxing Kenma’s ass to be familiar with him again. At the other end of the small table, Kenma’s panting and sighing, his eyes threatening to shut. Kuroo slams his finger to the hilt next to get his eyes to open wide again.
“AH fuck, Kuro—se-senpai,” Kenma mumbles. He moans, high and loud, when Kuroo slips another finger into him. The pace is slow again, but the stretch is new after the couple’s long time apart. Kuroo makes sure to press the pads of his fingers against Kenma’s walls as he continues to twist them inside of him. Once he decides Kenma can take it, Kuroo is relentless. He thrusts in and out of him so fast Kenma’s left stuttering when he moans and whimpers.
“Mmmh, ah ah ah! Feels g—oh god, nghh!”
“Shh, quiet. The door isn’t locked. You don’t want your parents checking in on you suddenly, do you?” It’s delicious, even addicting, how Kenma clenches around Kuroo at the question. That little detail. He chuckles, dark and drunk. “Ah, of course, you like that. My kohai’s a little slut.” He slips his fingers out just to land one strong slap on Kenma’s ass, then dives them back in to fuck him. It only makes Kenma sob, still too loud even as he bites his lip.
“Aish. I said keep quiet, Kenma-kun,” Kuroo warns before covering Kenma’s mouth with his own hand. He decides then to add another finger. Kenma’s feet lift off the floor at the sting, but he chases after his fingers anyway, cursing and drooling a little against Kuroo’s palm. Kuroo taps a finger against Kenma’s cheekbone and nods his head towards the notebook. “Keep reading. You need to get high scores for me, all right?”
Golden eyes try to focus back on the hasty scribbles and figures despite how dazed and wet they are. It’s endearing, really. Kenma always tries so hard.
“Always so good for me,” Kuroo praises as he kisses Kenma’s ear.
He pushes his fingers in deeper, but the three of them are too thick to thrust in too fast. Luckily, they’re also long. A brush against Kenma’s prostate has him whining against Kuroo’s palm. He holds out for a bit, eyes still trained on the pages, before they roll up and he lets go of the notebook. Kenma grips the edge of the kotatsu as Kuroo pistons his fingers in and out of him, just reveling in his boyfriend’s incoherent cursing.
Kenma’s knuckles turning white at his hold on the table signals Kuroo to ask, “Can you come like this? Untouched?”
“N-no! Kuro— nghh— please!” Kenma squirms, his ignored little cock hard and red, just waiting for attention. Kuroo decides to take pity on the third year and lets go of the little roleplay.
“Keep your voice down, okay?”
As soon as Kuroo removes his hand from Kenma’s mouth, his boyfriend bends an arm and bites at the sleeve of his sweater. The image of barely contained self-abandon goes straight to Kuroo’s own cock. But first, Kenma’s relief.
Kuroo thumbs at Kenma’s slit, already leaking with pre-cum. He pumps Kenma’s cock with the boy’s own mess. There isn’t much to stroke too, which has Kuroo grinning at how easily his hand covers Kenma. Filled and played with, Kenma cries and writhes on the tabletop like Kuroo’s own personal present. Kuroo can’t count how many dreams he’s had of the younger boy like this while he was away. So sensitive too. It only takes a few strokes for him to finish, painting the kotatsu futon white.
Kenma’s hips continue to jerk as he comes down from his high. Gently, Kuroo takes out his fingers, then wipes him and Kenma clean. Now properly clothed and safe from the cold December bedroom air, he pulls Kenma towards him and gathers the third year in his arms. Kenma’s legs stretch out under the warm kotatsu again and immediately melts beside Kuroo.
“How was that?” Kuroo asks softly.
Kenma buries his face in Kuroo’s neck before replying, simply, “Good.”
“Look at me for a sec?” Kuroo requests as his fingers card through long hair. And Kenma obliges, but only a little, his head still resting against Kuroo’s shoulder. Kuroo deems it good enough and dips down to give Kenma his kiss. Their lips are both cold and a little chapped, but they chase after each other anyway.
“I thought I’m only getting one?” Kenma asks against Kuroo’s lips and Kuroo gives him another.
“We’re going to keep reviewing tomorrow, so I’m just giving you some motivation.” The smirk he gives Kenma is answered with a roll of his eyes (typical) and another kiss.
“What about you though?” Kenma pats Kuroo’s lap gingerly. He’s still very obviously hard, even under a thick layer of pants.
“Ahhh, well. What if you help me study for my biochemistry class next?”
Kenma instantly backs off and stands at that. Without sparing Kuroo another look, he declares, “I’m going to bed.”
“Kenma-kuuun!”
