With an unemployed husband and mounting debts to a criminal relative, Riona is forced to work at a massage parlor where intercourse with customers is quietly permitted. She tries to protect her chastity, insisting that penetration is off-limits, but the enraged lender ties her up and violates her with his massive cock, awakening her masochistic desires. Once she begins offering full service, Riona becomes the shop's most popular woman. Even when the sadistic manager pounds her brutally, the kinky submissive wife cums again and again.
