Riko visits her male friend's place, intending to seriously discuss her boyfriend's unfaithful behavior. She's reached her limit with his constant cheating. However, an unexpected turn of events awaits. Unaware, she ingests an aphrodisiac secretly slipped into her drink by her friend. The drug spreads through her body, gradually heating up her womb. Noticing her condition, her friend grabs a camera and, driven by his own desires, reaches under Riko's panties. In that instant, he begins removing his own pants. Caught off guard, Riko hesitates but is forced to confront her own confusing emotions.
