Semi wouldn't have described Akaashi as someone who might like danger. He seemed to be the kind of person that always cross the road when the traffic allowed it, always put on a pullover in winter, always message his mom when he was outside, and over the top of all of that, he seemed to enjoy vanilla sex. And that was exactly why he was surprised to discover one of his boyfriend's kinks.

"- You're sure ? Don't feel obliged to do this." the pretty setter reminded him as he was cleaning the blade.

Knife play. Akaashi Keiji, eighteen years old, setter and captain of Fukurodani's volleyball team, always so calm and collected… Never judge a book by its cover, as they said.

"- I'm fine, Keiji. I would be lying if I said I'm not curious to see how it goes." Eita chuckled, admiring the scene from the bed.

The other didn't respond, but the soft smile tugging on his lips did it for him. Soon enough, he joined the ash blond. The latter was staring straight in his eyes, taking the time to appreciate the darkness that submerged them. Oh, he liked so much when his lover was letting his primitive instincts take the lead of his actions. The dark-haired boy settled his knees on each side of Semi's legs, his hands grazing over his neck and shoulders. The older gulped because the other setter looked almost feral.

They kissed. Somewhat softly at the beginning, but as Akaashi gained confidence, it grew heated and sloppy.

Eita almost didn't notice when the first cut came, the knife only grazing over his thigh's skin.

"- Is this okay ? Keiji breathed, breaking away slightly.

- Ye-yeah. Keep going."

Clothes flighted in the room and they both enjoyed the contact of their naked bodies. Catching sight of his now severely cut leg, the former setter of Shiratorizawa saw that it wasn't bleeding so much. However, he didn't have time to complain as he boyfriend straddled him again. Their aching lengths brushed together, making them both hiss. With his free hand, Akaashi held them, starting to pump slowly. They shared a kiss again, interspersed by grunts and moans. The younger quickened his pace, bringing the blade over Semi's ribs. He was so concentrated in not hurting his lover, it was endearing.

"- Please, Keiji, please…" Eita whined, even if he didn't know what he was pleading for.

The player of the owls went faster, adjusting his pressure on both of their cocks. But it wasn't enough, the other realized rapidly. He was craving for the knife to cut his flesh, more, deeper, longer. He was starting to like the stinging pain and how it increased his pleasure.

"- C-Can you… God, 'Kaashi ! Do that again !"

As always, he didn't need to express his feelings. The pretty boy torturing him could see right through his soul, as observant as he was. He was cutting deeper into his companion's other thigh.

"- You're bleeding a lot, Semi-san. Are you-

- Oh my god, Keiji ! Yes, I am ! Please, just-just don't stop. I'm almost-…

- Me too."

Once he was certain that the older was perfectly fine, Akaashi lost himself in the moment. His left hand was making travel the blade up and down the skin, drawing dark red patterns. His right hand, on the other away, was squeezing around their leaking crotches. Their pre-cum made it slide a lot easier. The blond left a hand to the other's nipple, rubbing it between his thumb and index. The reaction was immediate. He moaned loudly and his back arched. Eita kept on mistreating it, hanging his head down to reach the other one with his mouth. The first lick made Keiji sob. The latter switched his hands' work, going for the right thigh with the knife.

"- Semi-san, I can't, I-I can't take it anymore… Please, please, please, Semi-san… Ah !"

The aforementioned was now fully sucking on the pink button. He knew his boyfriend was close because he was begging. Just the fact that he was vocal was a good indicator. His own orgasm wasn't far, the wounds on his legs and ribs turning him on even more. He forced himself to keep working on both nipples, sometimes tugging on it a little too much because of his own reactions. But the captain didn't seem to care, quite enjoying it. His heart was beating fast under the former number ten's palm. He came with a shout of his given name, his whole body quivering. The spasms of his hand, added to the deeper cut than every other one before, brought Eita beyond the edge too. His groans were muffled by the other's chest still against his mouth as he stimulated him through his climax.

After several minutes, they both came down from their highs. Akaashi glanced over the bloody mess he had provoked and apologized profusely to his lover.

"- Don't. Semi panted. Honestly, that was the most exciting thing I ever did."

The reserved look on the dark-haired man's face was still saying "sorry", but his eyes… Oh god, his eyes had flames in them.
