Kenji and his coworkers often gather at their colleague Hiroshi's house after work. One day, Kenji peeks at Hiroshi's sister, the plain Kaichi, while she's taking a bath and sees that she has huge tits and a sexy body, making him horny and wanting to fuck her. Kenji took advantage of Hiroshi's absence to push Seiichi, who would do anything he was told and didn't resist at all. So we fucked as much as we wanted with the super sensitive and horny Seiichi.
