A/N: This is an attempt at seme!Kira. Sorry that it's so crappy, uni eats up my whole time!
Kira laid down the book he was reading when he heard his room's door open. Hisagi entered wearily and, without even bothering to close the door, threw himself face first onto Kira's futon. Izuru smiled knowingly, he was so used to his sempai using his room as a place for rest. But he didn't complain. That way they could at least spend more time together.
"Hello, Hisagi-sempai", he said, watching Hisagi's back move up and down with his breathing.
"Mhm", the dark-haired man replied, throwing his arms over his head. Kira stood up to close the door and when he was just to take a seat back, he heard Hisagi mumble:
"Fuck, my back hurts…"
Kira stopped abruptly, an idea appearing in his brain. He smirked to himself. Well, he wasn't exactly sure if his sempai would like that idea at that moment, but he could at least try. He spotted a small jar of hand lotion and grabbed it, then moved towards the bed.
Suddenly, Hisagi felt a warm weigh place itself on his lower back and heard a soft chuckle.
"Fuck, Izuru, what the hell…", he managed to mumble, face pressed into the pillow.
"Just relax, sempai", Kira replied, shifting to sit on Hisagi's thighs. He put his hands on the bigger man's broad shoulders and slowly stroked down along the spine, until he stopped on the kidneys, then stroked upwards, and repeated a few times, until he felt Hisagi's tense muscles relax.
"I think you should take off your clothes", he said in a low voice. Hisagi could totally see him blushing at the very thought of it.
"I can't", he murmured, "you're sitting on my ass."
He did it on purpose, of course. Even though getting Izutu off himself wouldn't be a problem, he was too tired to get up at the moment, so taking advantage of Kira's initiative seemed a great possibility.
Izuru's hands moved under Hisagi's body to untie his shihakusho. Shuuhei purred in delight feeling those hands on his chest, brushing his nipples and stroking his ribs while pulling the piece of clothing from under him… but they were soon gone. He felt some chilly liquid pouring onto his now naked back.
"What the…", he started, but soon Kira's hands smeared the cream all around.
Izuru first kneaded on Hisagi's shoulders. He was very tense there, just as he always was after a whole day of work. Then, he moved onto the muscles just beside the spine. He rubbed them in steady circles with his knuckles and the dark-haired man was soon sighing in content. The lower Izuru moved, the more audible the sighs were, and when he rubbed the ribs, Hisagi was moaning in a very meaningful way. Kira couldn't help blushing, but he was pleased with himself – he managed to make Hisagi relax, all by himself.
"Do you like it, Hisagi-sempai?", Izuru whispered into the dark-haired man's ear, leaning down so that his hands were rubbing Hisagi's shoulder blades.
Hisagi nodded at Kira's question, but he started to get impatient. His exhaustion disappeared and all he wanted to do was to get rid of his growing erection that was threatening to make a hole in the mattress. Izuru, being usually cute, could be such a tease sometimes.
"Oh… Izuru!", Hisagi moaned loudly when he felt Kira's fingers rubbing the tension off the most sore spot on his back. The massage seemed to return him all his strength and energy.
Hisagi knew he could wait no more. In one sudden movement, he turned around. Izuru fell beside him on the futon with a yelp. Shuuhei propped himself on his elbow, gazing into Kira's eyes.
The blonde was smiling innocently.
"Tell me, Izuru", Hisagi purred seductively, stroking Izuru's chest, stomach and then resting his hand on the growing, hot bulge in his hakama. "Where did you learn back massage?"
Izuru's eyes went dark at the implication.
