Three sharp raps pound at Nishiki’s door, followed by a “Senpai? Hey, you forgot the paperwork from the other day!” - both of which he doesn’t hear. He’s much too caught up in his current activity, which is fucking his s/o senseless against his desk. When Nagachika opens the door, it’s really Nishiki’s fault.
“Fuck, don’t you know how to knock?! It really pisses me off when people come into my territory uninvited.” Nishiki growls, snapping his hips against his s/o’s ass and filling them completely, showing no signs of slowing or ceasing whatsoever.
“I can - I can go - Just - Er -” Hide awkwardly shuffles to Nishiki’s desk, realizes what’s going on, and drops the paperwork on a vacant chair instead.
As he’s about to reach the door, Nishiki stills against his partner and grinds out a strained, “Wait.” Hide, fully expecting to receive the biggest verbal bitch slap since the beginning of time, turns and faces his senior, eyes closed. Nishiki pulls out of his partner, and reaches down to stroke himself as he turns to Hide.
“Join or go, the decision is yours, just make it quickly.”
Hide isn’t exactly sure how it happens. One moment, he’s sitting there and prepared to suffer whatever hell Nishiki’s capable of inflicting upon him, the next, he’s tugging off his clothes as if in a trance. He locks the door for good measure and walks over to the couple, unsure of what they want him to do. They move things to the bed, a space better suited for another person. Nishiki’s partner grabs his hand and pulls him in for a kiss, silencing whatever complaints or worries he has. Nishiki, a little agitated at being pushed to the side, intervenes by slipping his hand between the two of them, stroking his partner and grinning as he draws moans from them. Hide is a little out of his element, but wanting to prove to his Nishiki that he was right for allowing him to stay, he puts his lips to work. He dominates their s/o’s mouth, all tongue, lips and teeth as he kisses them ravenously.
It’s another few minutes of miscommunication, and tons of frustration on Nishiki’s part, before the settle into a good rhythm. Hide positions himself at their s/o’s entrance, only when first given the okay by Nishiki, and slams in, setting a quick pace as Nishiki jerks himself off. Normally, he hates it when others intrude on his territory, but dismisses the thought, because he finds it so incredibly hot. They take turns pleasing their s/o, and by the end of the hot, sweaty session, Hide isn’t sure how to feel as they’re all sprawled out on Nishiki’s bed.
“You tell no one,” Nishiki says lazily, though with an unmistakable twinge of danger. “Go.”
