Nagi, an adult college student who manages a campus club, joins the members on a training trip. As she massages them after exercise, the horny men become aroused and start touching her suggestively. She says they should stop, but her own desire keeps rising. After being made to cum until her body goes soft, she is penetrated and immediately climaxes again. The club’s only female manager is ultimately reduced to a sex toy for the members in an intense four-way orgy.
