Nagi Yasaka, an adult college student and the only female manager of a campus club, joins the members on a training trip. As she uses her skilled massage techniques to soothe the guys after exercise, the horny members become aroused and start groping her lewdly. Nagi tells them they should stop, but her own excitement keeps building. They make her cum repeatedly until her body is soft and slick, then ram their cocks into her and instantly send her over the edge again. The innocent manager is overwhelmed by pleasure in a four-way gangbang and ultimately turned into the club members’ shared fucktoy.
