Riko, a 30-year-old receptionist. That day, she longs to experience regret-free sex with a man she meets. To fulfill this desire, when toys are applied, she writhes in ecstasy, her entire body tensing from her toes upward. When engaged in intense intercourse with the male performer, she trembles and reaches climax repeatedly. Still appearing unsatisfied, she is invited by a pride-driven, highly-enduring male performer for a second round. Her legs spasm as she sinks into the bed with an expression of pure bliss—an utterly erotic scene.
