Here's a question. If you saw a woman handcuffed in a lonely place, you'd surely help her, being a kind-hearted person. But what if you were told that the key to unlock the handcuffs was inside her vagina? When you try to take the key, you can't help but see her female genitals. And the owner is still tied up. As usual, there's no sign of anyone around. Would you pretend to take a picture of the key and touch her vagina? Can you end it there? Her freedom is in your hands. And of course, beyond that... This time, we'll tell you the story of a woman who has been subjected to such a cruel act. No one will help her even when she begs for help, let alone help... A seemingly endless bondage situation. Tsubasa Mai is used as they please.
