“It’s so hot,” Genya groans, feeling absolutely disgusting by the way sweat is clinging to him like a second skin.
“Mm,” Sanemi hums, the sound vibrating through his chest where Genya’s head lies. “Probably be less hot if you laid in your own bed.”
Genya’s head jerks up with an offended scoff. “Hey!”
Before he can say anything else, Sanemi leans forward and kisses the pout right off his lips. It’s quick, almost smug, like Sanemi knew exactly what reaction he would get when he said those words.
“I’m just teasing, baby,” he murmurs, brushing sweaty pieces of hair from Genya’s forehead.
“Asshole,” Genya grumbles with no real bite.
He rests his head back against Sanemi’s chest with a huff, fingers tracing the familiar patterns of scars that mark his brother’s body. The distraction doesn’t last long though. The air is still and heavy in their bedroom—each humid breath practically suffocating Genya. And squeezing into this twin-sized bed with Sanemi certainly isn’t doing him any favors, but he’s far too stubborn to admit that now.
“Nemi,” he groans, burying his face deeper into Sanemi’s chest. “Can’t we turn the thermostat down some more?”
“Fuck no,” Sanemi replies instantly. “You can lower it when you start paying for it. Shit’s expensive.”
Genya bites back the urge to argue, to say he’d happily pay for it if Sanemi would actually let him get a job instead of just telling him to focus on graduation and college applications. But he knows good and well the heat makes them both snappy, and he’s really not looking for a fight right now.
“I’m gonna die,” he mutters dramatically instead, “And then when I’m a ghost I’ll haunt your thermostat.”
A sharp snort of laughter escapes Sanemi’s lips. He smacks the upside of Genya’s hand lightly before ruffling his hair for good measure. “Jesus, alright,” he chuckles, pushing against Genya’s shoulder. “C’mon. Get up.”
Genya sits up, slightly confused. But Sanemi offers no answers as he slips out of bed, making his way to their closet. He rummages around for a little bit before emerging with two towels tossed over his shoulder.
“Well?” Sanemi says. “Come on already.”
Genya sputters, but Sanemi doesn’t wait. He pushes open the door to their room, peeking around the corner.
“Nemi!” Genya hisses, tugging the blanket over himself. “I’m in my boxers! And so are you!”
“We’re fine,” Sanemi whispers back. “That’s all we’ll need. Now come on.”
Genya huffs, cheeks heating slightly in embarrassment, but he listens. He crawls out of bed, padding over to Sanemi and peeking over his shoulder into the dark hallway.
“Okay, I think everyone’s asleep,” Sanemi murmurs, barely audible. “But be quiet, you know how they are.”
He does. The kids always seem to have some sixth sense for when the two of them are trying to do anything without them. No matter if it’s just slipping into the kitchen for midnight snack or trying to sneak out for some alone time, they always seem to catch them in the act and of course want to join. Especially Teiko. Genya’s pretty sure she has superhearing or something.
But this time they manage to make it down the hallway without any doors bursting open and siblings demanding to know where they’re going. They tip-toe through the living room and kitchen until they reach the back door. Sanemi slides it open without a word, slipping outside barefoot and damn near naked. Genya could smack him. Instead he just grumbles under his breath, following Sanemi out.
“What the hell are we doing?” he whisper-shouts once the door is shut, glancing nervously at the windows to the kid’s bedrooms to make sure no one has stirred.
“You said you were hot,” Sanemi answers simply, tossing the towels onto a chair. “So let’s cool off.”
He jerks his thumb towards the new above-ground pool he bought just two weeks ago. It’s relatively small as far as pools go, but the kids were over the moon when Sanemi came home and set it up for them.
“You’re kidding,” Genya deadpans.
Sanemi shrugs. “Why not?”
“Nemi, it’s the middle of the night!”
“Shh!” Sanemi hushes, swatting a hand in the air. “So what? It’s probably the only time we’ll be able to use it without the kids all over us. I didn’t spend all that money just for them.”
Heat creeps up Genya’s neck, and he looks away pointedly.
“Whatever,” he mutters, making his way over to the pool. He climbs the plastic steps of the ladder carefully, pausing on the last one. He extends one foot slowly, dipping a toe into the water cautiously.
“Eek!”
He snatches his foot back immediately, the ladder wobbling slightly under him. Sanemi steadies it, and Genya can feel him climb up behind him.
“What is it?” Sanemi asks.
“It’s too cold!”
Sanemi scoffs, breath hot on Genya’s ear. “You were just whining about being hot.”
“Yeah but it’s freezing!” Genya argues.
Sanemi is silent for a moment, then he leans closer, hands finding Genya’s waist, lips pressing a kiss to his shoulder blade. “You know I love you, right?”
“Wh—”
Suddenly he’s shoved forward.
“NEMI!”
Genya hits the water with a splash, the cold shocking every muscle in his body. His limbs flail uselessly for a moment before he regains control. He breaks the surface with a gasp, arms wrapping tightly around himself. He turns around at the sound of laughter, finding Sanemi still on top of the ladder, one hand covering his grin as he chuckles at Genya’s dismay.
“You jerk!” Genya hisses, splashing water towards his brother in retaliation. But Sanemi doesn’t seem to mind, jumping straight in after Genya. He emerges from the water with a grin still on his lips.
“What’s wrong, baby?” he teases. “At least you’re not sweating anymore.”
“Fuck off,” Genya scoffs, swimming to the other end of the pool. Which is all of three feet away, but he likes to think the point still gets across.
“Baby. Come on,” Sanemi calls behind him, though he’s still unable to suppress his laughter.
Genya keeps his back turned, hands sliding up and down his damp arms to generate some heat. Yeah maybe he isn’t sweating anymore but now he’s fucking freezing to death. Jerk.
Hands find his waist once more, and while Genya doesn’t push his brother away, he doesn’t turn around either.
“Don’t ignore me,” Sanemi murmurs, planting a kiss on the back of his neck. “I was just messing with you. You’ve done it to the kids before.”
He has, but that’s not the point.
“Babyy,” Sanemi groans, arms coiling around Genya’s waist to pull him closer. He presses more kisses to Genya’s skin—his shoulder, his spine, his neck. He aims one for Genya’s cheek, but Genya turns his head at the last moment so it misses.
“Okay, okay,” Sanemi relents, squeezing Genya’s waist one more time before letting go. “I’m sorry.”
The words are simple, but they’re rare from Sanemi’s mouth and melt something inside Genya. He sighs one last time, just to be petty, but finally he turns around, wrapping his arms around Sanemi’s neck.
“You’re still a jerk,” he grumbles even as he allows Sanemi’s arms back around his waist and lets himself be pulled in closer. “Just lucky that you’re warm.”
“Glad to know that’s all I’m good for,” Sanemi chuckles, kissing Genya’s cheek.
“And don’t you forget it.”
Sanemi huffs a laugh, planting one more kiss to the corner of Genya’s mouth before tugging him closer, resting his head onto Genya’s shoulder. Genya smiles softly, running his fingers through Sanemi’s damp white hair.
These are the moments that always mean the most to him. The rare times Sanemi allows himself to soften, to be held, to be loved. It’s never been easy for him, not even after years of being together, but it’s worth it for moments like this. Sanemi’s head resting on him, breathing slow and steady, expression softer than it ever is when he’s awake. The kind of expression only Genya ever gets to see.
It’s almost funny sometimes. Genya can’t help but imagine how his friends would react to it—seeing their big, mean math teacher that they’re all so afraid of clinging to Genya like he’s afraid to let go. Or even Sanemi’s own friends who are lucky to get a pat on the back, maybe a quick, stiff hug once in a blue moon if they’re Obanai or Kanae.
They must think Sanemi hates touch, or maybe that he’s incapable of affection altogether. Neither is true, but Genya doesn’t mind being the only one who knows that. He likes knowing Sanemi’s softness is reserved only for him, that he’s the only one who will ever see his big brother so open and vulnerable. It makes something flutter in his stomach, even after all this time.
With a content smile, Genya tilts his head backwards to stare up at the stars. Or, well, he would if there were any stars to see. But tonight the sky is full of thick clouds, blocking out everything except some faint moonlight still peeking through. A small noise of disappointment slips out before he can stop it.
“What are you pouting about?” Sanemi asks, voice low as he lifts his head.
Genya sighs. “Can’t see the stars.”
Sanemi follows his gaze, looking up at the dark, cloudy sky. “Oh yeah,” he hums, almost to himself. “That sucks. Really killing the vibe.”
“The vibe?” Genya echoes, a grin tugging at his lips.
“Mhm.” Sanemi steps forward, slowly pushing Genya backwards until his back hits the pool wall. “Guess I’ll have to do something to fix that.”
“Guess so,” Genya agrees breathlessly.
Their lips meet, slotting together perfectly. Genya sighs into the kiss, hands sliding up to thread into his brother’s hair. Sanemi’s fingers dig into his waist, trying to pull him impossibly closer.
The kiss deepens slowly, Sanemi’s tongue tracing the seam of Genya’s lips asking for permission. Genya parts them with a small, needy sound that would probably embarrass him to death if anybody else heard. But it’s just Sanemi, who responds with a low groan of his own. Their tongues slide together, moving like a dance only they know the steps too. Small whines continue to crawl out of Genya’s throat, and Sanemi swallows each one eagerly, his hands wandering Genya’s body as they kiss—waist, hips, thighs, anywhere he can touch.
“Nemi,” Genya breathes, fingers tightening in Sanemi’s hair.
Sanemi’s lips trail down his jaw to his neck, pausing to suck gently on all the sensitive spots he knows make Genya squirm. He’s leaving marks, and Genya knows they’ll be a bitch to hide tomorrow, but he just can’t bring himself to tell Sanemi to stop now.
Suddenly, a cool drop of water hits the top of his head. Then another hits his shoulder, and a third on his cheek. Genya blinks, distracted from the feeling of Sanemi’s lips on his skin.
“Did you feel that?”
Sanemi pulls away with a frown, but before he can answer more droplets fall, pattering around them and forming small ripples in the pool. Genya tilts his head back, allowing the light sprinkle to hit his face with a small smile.
“Shit,” Sanemi mutters, looking much less amused. “Do you want to go back inside?”
“Nah.” Genya shrugs, pulling Sanemi closer. “We’re already wet anyway.”
“Good point,” Sanemi agrees easily, capturing Genya’s lips once more.
The rain picks up around them, but neither cares. They move together in a familiar rhythm, Sanemi’s teeth pulling on Genya’s bottom lip, Genya’s nails digging into Sanemi’s pale skin. A perfect moment, Genya thinks.
And then there’s a flash of white light, followed almost immediately by the deafening crack of thunder. Genya nearly jumps out of his skin, and Sanemi’s arms lock around him protectively.
“Okay, we’re getting out now,” Sanemi says firmly.
“Yeah, good idea,” Genya murmurs, scrambling to follow as they climb out of the pool.
As soon as the cool air hits him, Genya begins to tremble—fuck he hadn’t realized how cold he was. His teeth chatter together as they duck under the porch roof, and he doesn’t hesitate to snatch a towel from Sanemi’s hands and wrap it around himself.
Sanemi gives him an amused look but doesn’t comment, instead focusing on drying his own hair and skin. Another lightning bolt strikes, closer now, and this time they both jump at the resounding thunderclap.
“Alright, let’s go inside,” Sanemi mutters, tossing his towel over his shoulders. “And for fuck’s sake, be quiet. If Teiko catches us in our underwear she will never let us live it down.”
Genya chuckles softly, giving Sanemi a small nod. They creep back inside carefully, trying to move quick enough that they don’t soak the floor but slow enough that no one hears them. It’s like walking through a mine field trying to get past these kids.
With some skill and a lot of luck, they make it back to their room without a hitch. Sanemi carefully shuts and locks the door behind them, letting out a relieved breath. Genya wastes no time yanking open their closet, snatching up the first shirt and sweatpants he lays eyes on. He’s pretty sure the shirt belongs to Sanemi, but he really couldn’t care less.
He practically rips off his soaking wet boxers, using his towel to wipe off the remaining water before slipping on his sweatpants and then shirt. When he turns Sanemi is already dressed, but of course he still opts for no shirt. Figures.
“Still hot?” Sanemi teases, picking up both of their boxers and tossing them into a corner. They’ll probably remember to get them tomorrow. Maybe.
“Fuck no,” Genya mutters, breath shuddering. “I’m freezing.”
“Well c’mere then,” Sanemi murmurs, grabbing Genya’s hand and pulling him towards the bed.
They crawl in together, Genya curling up to Sanemi’s side the way he always does, head resting on his broad chest. Sanemi’s arms curl around his waist in turn, keeping him close just as another crack of thunder makes the house tremble.
“Good thing we got out when we did,” Sanemi mutters, exhaling softly.
“Mhm,” Genya hums, already feeling sleepy. He nuzzles closer, smiling to himself as Sanemi’s hand moves up and down his back in a comforting motion. He clings even closer, wrapping his legs tightly around Sanemi’s.
“Fuck!” Sanemi hisses, trying to jerk away. “Your feet are like ice!”
Genya just laughs, clamping his thighs down around Sanemi’s leg to hold him still as his toes slip underneath his sweatpants.
“C’mon, Nemi!” he giggles as Sanemi tries to break away. “I need you to keep me warm!”
Sanemi makes an indignant noise but the fight quickly drains from him with some muttered complaint under his breath. With a huff, he turns his head, pressing a kiss to Genya’s forehead.
“You’re lucky I love you.”
“I know,” Genya says quietly. “I love you, too.”
“You better,” Sanemi grumbles, but it’s softer now.
Genya looks up and Sanemi meets his gaze, a small smile of his own forming. They share one last kiss, slower this time. Just a gentle press of lips before pulling away. Genya lays his head back down, falling asleep to the steady beat of his brother’s heart beneath him.
