Rika Kawamura is a 21-year-old woman who looks quiet and inexperienced but is actually a kinky masochist. They usually meet at hotels, but today her casual lover visits her cluttered apartment for a change of scenery and some rougher play. Everyday details and a suspiciously familiar toy by the window only make the room more exciting. Rika leads him toward the bathroom with a needy look, obediently sucks his cock and takes a forceful deep throat. Back on the bed, he ties her wrists and teases her with a wand vibrator; being unable to move leaves her wetter than ever. He penetrates her without a condom and pounds her hard while she repeatedly cries that it feels good, showing exactly how wild and submissive she can become.
