Two Months Later
"Mirio?"
"Mm?"
The two boys were studying in Tamaki's room, sunlight filtering through the windows and illuminating the pages of scattered textbooks and journals. Mirio was dangling his head off the foot of the bed to read the book resting on the floor. His legs were stretched back towards the headboard, where Tamaki was sitting with a computer in his lap.
"Do you have plans tonight?" Tamaki's tone was casual, but in a careful way. Mirio twisted his neck around to look back at Tamaki.
"Uhhh… no? Do you?"
"I was thinking… that maybe we could…" Tamaki was nervous, nervous in a way Mirio hadn't seen in a while.
"...have sex."
They had done a lot of… stuff together. Except for that.
Mirio swallowed, trying to hide the panicked look that flashed across his face.
"Are you sure?"
"Yeah, I think." When Mirio seemed unsatisfied with that answer, he amended. "I want to try, at least. As long as you want to."
Mirio was silent for a long, long moment. He looked… Tamaki wanted to call it nervous, but he had never seen Mirio worry about these things before.
"Do you want to?" Tamaki pressed, and Mirio seemed to snap out of his reverie.
"Yeah, yeah! Of course. I just…" he rolled over onto his back, staring up at the ceiling. "...don't know what to do."
"You don't?" Tamaki raised his eyebrow, voice oozing sarcasm.
"Come on, you know what I mean. I'm just nervous." He was nervous, it was suddenly clear from the way his brows pulled together.
"Now you know how I feel," Tamaki murmured, but there wasn't any malice in it.
"You're sure?" Mirio breathed.
"Yeah."
"Okay," Tamaki had never seen Mirio look so embarrassed. He would be enjoying it more if he wasn't equally flushed.
"Okay."
There was silence, both their thoughts swirling.
Tamaki set his laptop down and crawled over to the foot of the bed to lay next to Mirio, who draped a lazy arm over him. They stayed like that for a while, content to dwell in their own thoughts.
"Tonight?" Mirio repeated softly.
Tamaki nodded.
"No alcohol involved, right?"
"It's not like that. I… I've thought about it a lot."
Tamaki's face burned at the confession as Mirio turned to look at him. He pressed a soft kiss to Tamaki's cheek.
"Tonight we take things at your pace."
It was slowgoing at first.
Tamaki had become a lot more comfortable in the last few months, comfortable enough for Mirio to undress him and run his hands along his bare skin, lavishing praise on the demure boy.
Comfortable enough for Mirio to stroke him without Tamaki shying away, letting noises spill in an unfiltered show of his pleasure.
That comfort quickly dissipated when Mirio asked a question that was brand new to the both of them.
"Can I finger you?"
Mirio could feel Tamaki tense. He was laying underneath Mirio, looking up at him with wide eyes.
"Only if you want to keep going..." Mirio reassured, pressing a gentle palm to Tamaki's cheek.
Tamaki fumbled for the pillow behind his head and pulled it up over his face, concealing his embarrassment.
Mirio knew the drill well enough by now. For all the progress Tamaki had made, he was still embarrassed by what Mirio might see in his expression.
"Okay," Tamaki's voice was muffled beneath the pillow, but his tone was firm.
Mirio quickly focused his attention on Tamaki's exposed body, easing his legs apart with gentle pressure.
He watched Tamaki's slender fingers clench the pillow tighter in anticipation. Mirio pressed gentle kisses along the length of his slim chest, murmuring encouragement.
"Just relax for me, okay?"
The pillow jolted as Tamaki nodded.
Mirio's hand slipped between Tamaki's legs, putting gentle pressure against his opening with two slick fingers. He could feel the other boy tense.
"Relax…"
Mirio murmured and soothed between chaste kisses down Tamaki's stomach, waiting each time until he felt the tension in the other boy unravel before he massaged his fingers further.
For a while Tamaki was silent, silent enough that Mirio began to worry about continuing.
"Is it okay?"
The noise Tamaki made was unclear, but he removed one hand from the pillow long enough to form a meek thumbs up.
It was only when Mirio was deep enough to let his fingers stretch and curl inside Tamaki in a gentle, pulsating rhythm that he felt the other boy begin to react.
His breathing quickened to shallow pants that were muffled through the pillow fabric. Mirio watched the way his chest rose and fell more rapidly the faster Mirio moved, the way his legs seemed to twitch, bending and slipping against the sheets beyond his own volition in response to the increasing pressure of Mirio's fingers inside him.
After several minutes of Mirio's dexterous work and low-toned encouragement, Tamaki had dissolved into pants and whimpers.
A particularly sharp thrust of Mirio's fingers made Tamaki cry out and his head lolled to the side, peeking out from under the pillow long enough for Mirio to catch a glimpse of sharp canines clutching at his trembling bottom lip.
The sight was enough to make Mirio impossibly harder than he already was.
He pressed deeper without thinking, and Tamaki gasped.
"Ahh.. don't…"
Mirio retracted quickly.
"What's wrong?"
Tamaki's white-knuckled grip on the pillow relaxed.
"If you do that...m' gonna finish…" he murmured. Mirio could see an embarrassed flush coloring Tamaki's neck and collarbones.
"It feels good?" Mirio's voice was part surprise, part delight.
Tamaki whined by way of a reply.
Mirio looked down at the place where he was straining against his boxers and swallowed.
"Tamaki, will you look at me?"
The other boy didn't move, but when Mirio grabbed the corners of the pillow and began to tug he didn't resist.
When Mirio set the pillow to the side he revealed Tamaki's beautifully nervous expression, eyes cast sideways to avoid the other's gaze.
"I don't know if I can…" Tamaki's voice wavered.
"If you want me to, you know… put it in…" Mirio hesitated, watching Tamaki's reaction. "Then I just want to see that I'm not hurting you, you know?"
Tamaki nodded faintly, but his brows were still knit with that all too familiar concern. Mirio cast about the room for ideas, and then seized on the blanket bunched up at their feet.
He pulled the corners up over their heads with a flourish, bathing the two in darkness for a moment. Tamaki's face came back into view as his eyes slowly adjusted.
"Is this better?"
Their faces loomed inches apart from each other, but the darkness under the blanket lent a fuzziness to their features that helped obscure Tamaki's expression save for the shine of his dark eyes and the lines of his nose, cheeks and mouth. Mirio could see him just enough to make out his expression, and Tamaki could still feel half-concealed in the darkness.
"Yeah," Tamaki breathed.
Tamaki lifted his hands and tucked his fingers into the waist of Mirio's boxers, easing them down and off to reveal how painfully eager Mirio was.
"W-will it fit?"
"It's okay, we'll go slow." Mirio soothed, pressing a kiss to his forehead. "Ready?"
Tamaki took a shuddering breath and nodded. He peered through the dim space under the blanket, trying to slow his breathing as he watched Mirio reach outside the blanket and fumble for a condom and lube, deftly preparing himself.
Mirio reached for Tamaki's hand, squeezing it encouragingly as he laid himself out between the smaller boy's spread thighs, his chest pressed to Tamaki's. The heat between their bare skin was making Tamaki's heart throb dizzyingly. Mirio's weight was resting on his elbows, his other hand still clutching Tamaki's.
"I'll stop if you want me too, okay?"
Tamaki nodded, chewing the corner of his lip.
"Just relax…" he whispered, again and again like a prayer into Tamaki's ear as he eased himself inside of the other boy with gentle pressure.
Tamaki inhaled sharply, his nails digging into the back of Mirio's palm where their hands intertwined.
Mirio pressed gentle kisses to the other boy's lips, hoping the sensation would distract him as he pressed deeper, deeper as slowly as his own body would allow when the friction felt so good. He swallowed Tamaki's gasps and whines in eager kisses until he felt moisture wet his face.
Tears were welling in Tamaki's lower lashes, his dark eyes narrowed and glistening.
"Tamaki?" Mirio asked, pulling back just far enough to take in his expression. "Does it hurt?"
"Mm," he whined in reply, eyes traveling down to the place where their bodies were joined.
"Should I stop?"
Mirio's breath was short, his pupils blown wide with excitement. His muscles were trembling in anticipation. He wanted to move, and Tamaki could see that desire written all over his face.
"Don't, it's okay… don't stop…" Tamaki exhaled.
Mirio pulled his hand from Tamaki's, swiping his tears away with his thumb.
He was deep enough, deep enough to ask.
"Can I move?"
Tamaki chewed his lip as he nodded.
Mirio took a deep, shaky breath and let his hips begin to rock, ever so gently, or as gently as he could bring himself to when the sensation was sending him sky-high.
His lips ran over Tamaki's throat and down to his collarbones, kissing them when he could and panting over them when it felt too good to focus.
His hips jerked more sharply than he meant, and Tamaki made a cry he hadn't heard before.
Tamaki's expression had completely transformed after moments of Mirio's thrusts.
The pain that had painted his expression before was replaced by shock. Mirio wasn't sure what to make of it until he watched Tamaki utter an involuntary moan before quickly pressing his hand over his own mouth, eyes wide.
Pain had given way to pleasure, a pleasure so intense it was clear Tamaki didn't know what to do.
"M-Mirio…" Tamaki gasped, and the sound of his name on the other boy's ragged breaths made Mirio's head spin.
His thrusts deepened, his thoughts now consumed by the singular purpose of seeing Tamaki undone. The smaller boy clutched at Mirio's arm with one hand while the other flew up to tug at the strands of his own dark hair.
"Ngh… that's- ah!" Tamaki's words dissolved into desperate moans. His head was tipped back into the mattress, eyes closed, mouth open.
"God, Tamaki…"
Mirio could feel himself losing control, the sight of the other boy, the sounds he was making all pushing him over the edge.
But he wanted Tamaki to finish first.
He pressed his chest tight to Tamaki's, pinning the other boy's throbbing member between their stomachs.
Mirio's thrusts rolled their bodies against Tamaki's length, the friction from both sides sending Tamaki into fits of ragged breathing.
"Miri-ah!"
Tamaki came without warning, his back arching off the mattress. Mirio dropped his forehead into the hollow of Tamaki's shoulder and worked himself over the edge, his hips pressed tight against Tamaki, coming to a rest with one last shudder.
Mirio's hair was falling down over his eyebrows in a mess, his chest heaving with each breath.
Tamaki's eyes were glassy, his mouth still slightly parted when Mirio leaned down to press a tender kiss to it.
He pulled out of Tamaki slowly, seeing the other boy wince as he did, and threw the blanket off of them. A rush of sunlight and cool air flooded his senses, clearing the haze that had settled over him. Tamaki looked at the sticky substance spread between their chests and threw a hand over his eyes in embarrassment.
"It felt good, huh?" Mirio smirked playfully.
"Too good…" Tamaki whined. He looked back up at Mirio, something on the tip of his tongue.
"You… looked really good, like that," he confessed hesitantly.
Mirio beamed.
"Me? You should have seen yourself," He pulled Tamaki up to sit and gave him a kiss that the other eagerly returned.
They stared at each other in silence for a moment, just the sound of their breathing slowly growing softer.
"Thanks… for waiting for me."
Mirio squeezed Tamaki's hands in his.
"You're always worth the wait."
