When I woke up, hemp rope digged into my whole body and I couldn't move. Mayuko, who is confused by the unusual situation, asks her son Satoshi for help, but Satoshi just strokes her body with her eyes bleeding. It was Satoshi who tied Mayuko while she was sleeping. I noticed that Satoshi had a special habit. But no way to choose for mothers ... Mayuko desperately tries to escape, but hemp rope bites into her body and deprives her of her freedom. There was no way to resist Mayuko.
