Akiko’s Stepdad has a secret room where he practices BDSM. One day Akiko heard strange noises coming from house’s basement. Being a very curious “kitty”, she went down there to investigate. The door was slightly open and she saw her Stepdad tying her mother up over a bed. He began to touch her mom in a dirty way and penetrate her holes. Akiko, now eighteen, had a huge sexual appetite and, maybe surprisingly, she got turned on so badly to have her mind going wild. Akiko has already been in the punishment room two times but lately she doesn’t seem to be that interested. Every now and then she “jokes” with her stepfather, but there have been no opportunities to go because her mother is always around. One day, however, as soon as she came back home after school, Akiko met her stepfather who, seeing her dressed provocatively, scolded her and ordered her not to go out dressed like that again. An argument arised between the two. Akiko says that she is now an adult and she can do whatever she wants. Her stepfather, seeing they were alone in the house and that she didn’t want to listen, grabbed her by the arm and took her to the punishment room to teach her how to behave. Will Akiko learn the lesson?
