Chapter Text
Nitori tries to tell himself that he'll spend the whole summer on volunteer work, researching for volunteer work, training, looking into universities, and preparing for all of his upcoming classes; but all Nagisa has to do is text i'm bored, come make out with me, and it's like a tug on a metaphorical leash.
Nagisa's parents don't even seem to notice that their son is entertaining one friend in particular more than the others - they never knock on the door, or barge in at six in the morning and find them in bed, curled up together and half-naked with an empty pizza box on the floor and a collapsing stack of swimming magazines in the corner. Nagisa never seems to worry about it, so Nitori doesn't either. He wonders, sometimes, if they really are that preoccupied with work or if they're aware that Nagisa is having a whirlwind summer not-romance and would rather leave him to his own devices. Or maybe they're just lucky.
Entire days pass by like that; their shift at the shelter, then dinner, bath, goodbye kiss, "it's not like you have to go to home", impromptu sleepover...
It's the stickiest summer they've seen in years. So when Nitori stays the night, it's only natural that they discard their shirts, and then, as the days pass and the nights grow hotter, their sleep shorts too.
And after that, it's a barrier discarded altogether.
Because when Nitori wakes up in his underwear with kicked-off sheets and decides he wants to start the day with a kiss, he can't exactly tell Nagisa to put his clothes on first. So he bumps their foreheads together, softly, and his eyes are closed but he can feel the sweep of Nagisa's eyelashes against his face as he blinks himself awake. He pulls the smaller boy closer by the waist, easily, their bare skin brushing all over, the hard muscle of Nagisa's lower abdomen against his and then -- wow -- a startling insight into why Nagisa is always up and in the shower nine-out-of-ten mornings after Nitori stays over.
"Do you always wake up like that?" Nitori asks, genuinely, as Nagisa shifts to bury his face in Nitori's neck, nuzzling at the bruised-bitten skin there.
"You caught me," Nagisa tells him, and throws a leg over Nitori's hip.
oOo
The second time Nitori makes Nagisa come is just a few minutes later, and he thinks the 'makes' is an understatement. He doesn't pull the blond towards his climax like the moon pulls the tide; he just is, underneath Nagisa and all wrapped up in his arms, and he feels it approaching by the way Nagisa starts to gasp into their kisses and grinds harder against Nitori's hip. It's so hazy and hot outside that they're sticking to each other and damp and it's anyone's guess how they got here, like this, but it doesn't matter, Nitori thinks, because they always seem to.
And then those words tumble out of cherry-flavoured lips all at once, between two breaths, "Is it okay if I--?"
Nitori doesn't make him wait. "It's okay," he says, and opens his eyes to watch the way Nagisa's close, his golden lashes fanning across flushed cheeks.
He makes quite the picture. The erratic flex and pulse of his abdomen and the trembling of his thighs against Nitori's bare hips - he tries to capture this, to save it in his memory because he will definitely need this image in, oh, about five minutes when he wriggles out from under Nagisa and makes a beeline for the shower where he can finally relieve some of the tension that's been building in him for as long as Nagisa has been sitting atop him, taking his pleasure.
"Wow," Nagisa breathes out when, Nitori assumes, he gets his ability to speak back. He shifts himself to lie on the bed instead of on top of Nitori's body, head on the pillow but eye contact unbroken, still smiling like he actually, physically can't stop. "That was really good."
"It was?" Nitori tries to preserve some modesty and drags the sheet up from where it's pooled at the bottom of the bed, letting it rest around their hips.
He's fidgeting a little, and he knows Nagisa has noticed when he sees the slow, proud smile that unfurls. Nagisa moves closer, making a sort of mm sound while he does; and then he rests his head on Nitori's chest like he's worn out. "It feels so much better than when I do it on my own, you know?"
"Y-yes," Nitori nods, and then blushes hotly. "I mean, that's what I've heard."
"Well it's true. And I don't mind," Nagisa all but declares, (he is not quiet), and his hand skitters down to Nitori's waistband, fingertips brushing the elastic, "if you want me to take care of you, too. More directly?"
Somehow their lower halves have become tangled together - in some ways it's inevitable, considering they're sharing a single bed. Nitori takes the opportunity to tease the back of his calf against Nagisa's leg - teasing the way Nagisa is teasing at the band of his underwear. It feels surprisingly good. Intimate. His arousal isn't dying down at all and he blushes all over again.
"What would you do?"
"Whatever you want," Nagisa promises. "I'd do it like how you do it when you're alone. You could tell me. Show me how?"
Nitori bites his lip. "Nagisa..."
"No?" Nagisa kisses Nitori's neck, but holds back on the teeth. He must know that those are the key to Nitori's heart, by now; or the key to his underwear, at the very least.
Nitori tilts his head back, giving better access. He watches the sunbeams shift across the ceiling. "...I think you would laugh."
"At what?" Nagisa asks between kisses. His lips travel up to Nitori's earlobe, and then down again until he reaches the spot he /really/ likes -- and then he lingers, does nothing but press one chaste kiss after another against the healing bruise that's already there.
"At my face... the face I'd make." Nitori can barely admit it, it sends embarrassment down to the tips of his toes. "And my, um... noises. I don't really know what I sound like..."
"Your face is always cute, Ai-chan." Nagisa comes up to eye level again, and Nitori catches the earnest look, his eyes way too bright for his time in the morning. "And so are your noises."
"You're seducing me," Nitori says, shyly, but he fumbles to place his own hand over Nagisa's on his abdomen, sliding it down, down...
He's had a hundred million fantasies, but none of them quite compare to the way it feels. None of them took into consideration the way his heart would be beating so fast; the ever-present and reassuring warmth of Nagisa's body pressed alongside his; or the way Nagisa whimpers at the contact, at the moment when Nitori's back arches and his breath hitches, as though their pleasure is one and the same.
oOo
Nitori summons all of his willpower while he's standing at bathroom sink.
The room is swirling with steam from the shower, the water warming and the little window closed. Beside him, Nagisa is preparing to go in, already undressed with a towel around his waist. They're sharing the mirror; Nitori brushing his teeth, Nagisa taking a quick picture of himself, and Nitori really hopes he's keeping him out of the frame because he doesn't want to see this online later, shower with ai-chan!!!! ≧◡≦, Nitori with a mouthful of toothpaste and fresh lovebites all over his bare chest, looking even darker under the harsh lighting.
"We have to stop this when we go back to school. T-this," he clarifies, pointing at the most obnoxious of the lovebites. Furious, deep red on the side of his neck, and so huge that he can't tell if it's an amalgamation of several smaller ones, or if Nagisa unhinged his jaw at some point during their last make-out session.
"How come?" Nagisa asks, pouting at the camera. Nitori can see the caption now; ai-chan asked me to stop marking him up, why?? ┐(‘～`；)┌
Nitori spits into the sink. "Rin-senpai noticed."
Mouth dropping open in surprise, Nagisa stops what he's doing and turns to him. "You didn't say anything!"
With a shrug, Nitori starts filling up his glass to rinse. "He thought they were from Kou-kun, at first, and he was mad. But now he knows they're not. So I didn't think it would matter until after the summer." He watches the tap water drain, swirling, and there's a flash as Nagisa takes another picture. "And I didn't want to stop, but... people started talking about it at practice and I think we should be more, um, discreet. I'll miss them," he adds, tracing his fingertips over some of his current favourites. "They made me think of you all week, during the semester."
There's the tap-tap of Nagisa typing something, but Nitori looks over just in time to see his faint smile. ""Aw, quit tempting me, Ai-chan." His fingers flying over the on-screen keyboard; he doesn't even look up to speak. "I need to shower or I'll be gross all day."
Nitori shifts from one foot to the other, smiling at Nagisa's hazy reflection in the mirror. "We could, um." He turns off the tap and moves to stand behind Nagisa, wrapping his arms around his waist, resting his chin on his bare shoulder. It feels natural, and Nagisa doesn't react to it at all until Nitori says, "We could save water, if you want."
"Now who's seducing who?" Nagisa jokes, but he puts his phone away, and Nitori's heart only beats faster.
