The Twin's Forbidden Game
Read the storySakusa and osamu are together and they are a perfect pair. Just not in bed- it was enjoyable yeah, it was pleasurable yeah. But was it memorable, was it exhilirating ? No. It was aproblem for sakusa. Thankfully enough Sakusa and Atsumu (osamu’s twin brother) are very very compatible in bed. So they become fuck buddies behind osamu’s back figuratively and literally. They especially like the thrill of fucking when osamu is in the room, in the other room, or in the house, or some other people seeing them fuck. They both enjoy rouch, marathon sex, multiple orgasms that seem to not end until they can no longer move.
