New student Minori attracts attention from male club members with her charm and cuteness. However, two jealous senior girls, driven by envy, plot to ruin her. During a drinking party at someone's home, they resort to underhanded tactics—spiking her drink with a diuretic, forcing her to drink excessive amounts of liquid, and even blocking her access to the toilet. Pushed beyond her limits, Minori ends up wetting herself. Overcome with humiliation and panic, she is stripped naked, then subjected to public urination and forced blowjob. What began as a rowdy drinking game quickly spirals into a creampie gang rape.
