One appearance only: Kayo Ryuonji is an extreme masochist who says amateur sex no longer satisfies her and begs professionals to torment her without mercy. Six segments push her fantasies to the limit: a revealing kink interview, a brutally intense three-way fuck, rough cock worship, immobile restraint orgasms, violent play with her bound body, and an intimate hardcore private sex shoot. As the punishment drives her wild, she moans that the monster inside her keeps demanding more.
