Her son, threatened by yakuza over unpaid debts and fearing for his life, offers his mother Yuki Tanihara's body as repayment. Yuki is kidnapped and bound, forced to orally service a man until he cums inside her mouth. Treated like a pet by a deranged boss, she's paraded naked on a leash with a collar around her neck and subjected to public forced masturbation. Made to gyrate on a strapon vibrator, she's forced to pee herself while restrained. Enduring every imaginable humiliation, she's then tightly bound and tortured to the point of convulsing orgasms, screaming in tears. Finally, a sympathetic underling rescues her, dressed in a wedding gown, and makes passionate love to her as if it were her wedding night.
