Tatsuya can't help but want to have sex with her. However, because it is her home, I am frustrated with the state of entrustment. So when I passed by the living room to go to the bathroom and cool my head, I witnessed her mother Kumi masturbating in the kitchen. What's more, while calling Tatsuya's name... After that, when Tatsuya passes by the living room on his way home, he meets Kumi relaxing in a bath towel. While talking, Kumi's bath towel kicks into her skin, and Tatsuya can't help but attack Kumi. It was Kumi who refused, but it was pointed out that he was masturbating while calling his name, and he could not resist.
