Summary
Hand wrapped around himself, Gen kept his eyes locked on the screen of the monitor like his life depended on it as he watched the two men ravishing each other as if they had something to prove. Knowing Hoshina, he probably was doing just that. Proving that he was better at fucking in order to just piss him off. But the thing was, he really didn’t care, not when the man under him was as fucking tempting as he was. Kafka was on his back with his upper body aimed towards the security camera that was at the corner of the room, his skin flushed and sweaty, chest jiggling with every harsh thrust into his body as his mouth hung open and tongue lolled out like something out of a gooner manga that Gen would have snuck past Hasegawa before growing a spine and making him regret snooping through his mail when it was delivered a few years ago. And his voice... he was all breathy and whiny in a way that sounded like sin. His deep rumble sounding divine as he practically mewled in pleasure as he allowed the smaller man to do whatever he wanted with him.
It was hot as fuck.
