Five years into her marriage, the beautiful wife, Jun, has fallen into an affair with her husband's boss. This is no ordinary affair—Jun has established a master-servant relationship with her superior, enduring training sessions he administers at the office. In the living room, she is tormented with a vast array of sex toys, climaxing uncontrollably. Forced to masturbate just beyond the door of a room where her husband is present, she struggles to suppress her moans while overwhelmed by intense pleasure. When her husband's business trip schedule changes unexpectedly, she is dragged into a room and immediately forced into a double deep throat by a colleague. She swallows the cum shot into her mouth, then is led to bliss through a creampie threesome training session designed to get her pregnant.
