A rookie trainer named Masami, who works at a certain gym, takes an interest in a special drink made by a sports doctor and decides to drink it. However, it turns out to be a drink laced with aphrodisiac effects!!! She tries to suppress her heated body with reason, but her rationality gradually collapses. Like a bitch in heat, she craves cocks, becoming enslaved to the aphrodisiac, and devours the bodies of male members, reaching continuous orgasms!
