Female student Eina invites her neighbor, a married woman named Sakura, to her room. The lesbian Sakura brings a bento box laced with sleeping pills and, after the meal, steals a kiss from the unconscious Eina, beginning to grope her soft, young skin. In that moment, Eina wakes up and spends the night trying to soothe her heated body, but the stimulation is insufficient, leading her to visit Sakura's house the next day. Immediately, Eina is made to swallow pills and transforms into a body that cannot stop urinating.
