Work Text:
“I’m not sure I get number 16,” Yamaguchi bites his lip as he taps the end of his pencil on the page.
He’s laid out, flat on his stomach on Tsukishima’s bed, like he always is when they come to his house to study after school. It’s a common sight for Tsukishima, as he leans back in his chair at his desk, craning his neck to turn to see Yamaguchi stuck on a problem.
Rolling his chair to the edge of the bed, Tsukishima leans his elbows next to Yamaguchi’s shoulder, peering over to read the problem he’s stuck on.
“It’s a conjugation of the verb,” Tsukishima explains, pointing his long index finger over the text above the question.
“Yeah, I don’t even know what conjugation means, Tsukki,” Yamaguchi laughs.
“Well, then you’re a lost cause,” Tsukishima teases, rolling back to his desk.
“Come on, Tsukki!” Yamaguchi giggles. “We’re supposed to be studying together, but you’re always so far away,” he pouts.
“We’re literally two feet away from each other, Yamaguchi. What more do you want?” Tsukishima rolls his eyes as he turns to stare at Yamaguchi.
“You could come over here,” he pats the space next to him on the bed.
“We don’t both fit on my bed,” Tsukishima states, flatly.
“We’ve never tried,” Yamaguchi goads, smiling at Tsukishima.
“Ugh, fine, if it’ll shut you up,” Tsukishima sighs. He gathers his notes and text book and drops them onto the bed next to Yamaguchi’s as he gently lays on his stomach next to his best friend.
Holding his breath, Tsukishima lies still as the bed bounces at his added weight. His knees bent and ankles propped up on the headboard, he relaxes as the bed stops moving.
“See?” Yamaguchi laughs, causing the bed to shake again. Tsukishima just rolls his eyes and opens his book back to the page he was on.
After a few minutes of reading and jotting down his answers, Yamaguchi leans over and lays on his side. His elbow propped under him as he rests his head in his hand.
“You know,” he breathes onto Tsukishima’s cheek. “I don’t think we’ve ever shared a bed before.”
“Because I’m a giant and need my space, Yamaguchi,” Tsukishima says, closing his book and tossing it to the floor in front of him.
The action causes Yamaguchi to lean off balance, the movement of the bed pushing his front against Tsukishima’s side and shoulder. His face pressed against Tsukishima’s cheek.
“Sorry, Tsukki,” Yamaguchi whispers in his ear as he tries to push himself off of him, not knowing where to place his hands to help him up.
Tsukishima’s heart races at the closeness of his lips to his ear, the way his warm breath tickles his hair under his glasses. His body pressed against him makes him stiffen, not moving or breathing until Yamaguchi inches himself away.
“I guess that’s why we don’t share the bed, huh?” Yamaguchi laughs nervously, laying on his back and staring up at the white ceiling.
“I guess,” Tsukishima manages to nod and calmly resuming his note taking.
“Have you ever-“ Yamaguchi stops himself, not sure how Tsukishima would react to his personal and intrusive question, even though he knows the answer.
“You know I hate when you do that,” Tsukishima huffs, referring to Yamaguchi cutting himself off when he’s speaking.
“I just, was wondering, if you’ve ever,” he closes his eyes and rushes the next part of his question. “Slept in the same bed with someone else?”
“I mean, I’m pretty sure I’ve slept in my brother’s bed as kid, even my parents,” Tsukishima answers, furrowing his brow.
“Not like that,” Yamaguchi sighs at Tsukishima answering so literally. “I mean like, you know, with someone, now,” he clarifies, still looking up, not meeting Tsukishima’s eyes out of nervousness.
“Oh, well, then no,” Tsukishima says slowly. Afraid, for some reason, that Yamaguchi will judge his lack of experience, even though he knows they both have never done anything like that before.
“Me, neither,” Yamaguchi sighs. “I’ve never even held hands or kissed anyone,” he admits shyly.
“Me, neither,” Tsukishima whispers.
Finally, Yamaguchi turns his head to meet Tsukishima’s eyes. A thought twinkling in his eye.
“Tsukki?” He says softly. “Should-“ he gulps down his words, even though he knows Tsukishima will scold him for it, he can’t let the words escape his lips for fear of scaring him.
Tsukishima’s eyes are shining intensely, boring into Yamaguchi’s as he slowly leans into Yamaguchi’s space, hovering slightly over his body.
Yamaguchi can feel Tsukishima’s heart racing in his chest on his shoulder. His eyes dancing over Tsukishima’s face, looking for a clue that this is really happening and that he wants it to happen too.
“We-“ Tsukishima says, his breath on Yamaguchi’s lips as he lingers above him.
Lifting his head slightly off the bed, Yamaguchi closes the gap between their mouths. Lightly pressing their lips together, in an experimental kiss.
Both of their eyes stare into each other as they slowly part their lips, fitting them together like they’ve seen in movies.
Yamaguchi is the first to close his eyes. They flutter closed as Tsukishima gently presses him back down into the bed, letting out a soft moan into Tsukishima’s mouth as he does so.
The sound makes Tsukishima’s heart flutter and he closes his eyes as he quietly gasps at Yamaguchi’s hand trailing up his side to run his fingers in his hair.
Breathing each other in, Tsukishima pulls away from Yamaguchi’s mouth. Staring down at him with a soft gaze, that gradually turns into sudden concern.
Pushing himself up and away from Yamaguchi, Tsukishima sits up on the bed at the opposite end, internally freaking out after just having kissed his best friend.
“I’m sorry,” Tsukishima whispers. “I shouldn’t have-“
“No, I was the one who brought it up,” Yamaguchi blushes brightly, sitting up, pulling his knees to his chest, staring down at his socked feet. Pressing his pink cheeks between his knees as he bites his lower lip.
“I didn’t-“ Tsukishima blushes too. He doesn’t know how to speak all of a sudden and can’t get his voice to stop shaking.
“Tsukki, it’s fine,” Yamaguchi shrugs, hoping he sounds calm, for Tsukishima’s sake.
“It’s fine,” Tsukishima repeats. Slowly starting to relax as he leans back against the headboard.
“Totally fine,” Yamaguchi nods.
Sitting in the tight silence of the room, they both avoid eye contact with the other. Waiting for the other to say something, anything, to break the tension.
“So, I guess now we won’t be so freaked out when we actually kiss someone, right?” Yamaguchi finally has the nerve to voice his thoughts.
“Yeah,” Tsukishima nods, feeling the awkwardness slowly dissipate. “That was like an experiment,” he adds.
“Yeah, like for science,” Yamaguchi chuckles.
“For science,” Tsukishima repeats, pushing up his glasses.
“Boys! Dinners ready!” Tsukishima’s mom calls up the stairs.
“We should eat!” Yamaguchi exclaims, jumping off the bed and heading around to the door, smiling over at Tsukishima like he always does, like nothing ever happened.
“Yeah,” Tsukishima smiles back at him, like nothing ever happened.
