Akiko’s Stepdadad 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. So, after few days, she had a plan in place to blackmail her stepdad in order to get him in the basement again… Down in the Punishment room…
