Momo-chan is a lively, cheerful college girl who seems to get along well with others. While attending university, she also leads a real-life amateur vixen lifestyle, visiting couple's cafes with her fuck buddies. However, having grown bored with ordinary sex with guys her age, she becomes intrigued by a gangbang circle she discovers on social media—and ends up applying on her own. Her motivation isn't mere curiosity, but a genuine, deep desire to be dominated and ravaged. Impressed by her enthusiasm during the interview, the circle introduces her to their group of perverted members. Dressed in cosplay, she's brought to a gangbang party, showing zero interest in one-on-one sex. Instead, as a true masochistic beast woman, she eagerly throws herself at the mercy of multiple men, fully submitting her body to their raw, bare cocks—an explosive debut that draws intense attention. Her pursuit of visceral pleasure unleashes her full creampie slut potential, earning high praise from all members of the gangbang circle.
