Caught in an incestuous act... A masochistic, mature, big-breasted housewife tutor becomes a sex toy for her abusive child. (JYMA-087)

Miki, a former tutor who was a cram school teacher before marriage, quit her job after getting married to support the family. However, although her husband is a serious workaholic, their nightlife is dull and he is sexually unsatisfied. It was then that a student showed her his cell phone, revealing a picture of them having an affair, which shook Miki. From then on, she was subjected to intense sexual harassment and coercion. Not only her student's son, but also her friends and father treated her like a masochistic pet, reducing her to a sexual toy.
