A dark married woman training circle is held regularly in the Kanto area. From the "M Slaves Wanted~" bulletin board, today, one sensual woman came to entrust her mature body in order to have her wishes fulfilled. "I haven't had sex with my husband for several years. I'm frustrated. I want to be seen in a perverted state..." Sae-san is 40 years old. She is also interested in bondage and would like to ask for it. The man's condition is that he is allowed to film when they meet. The crazy slave training between the lewd married woman and the training members begins.
