her mother, kanzaki kumi.

Tatsuya can't help wanting to have an affair with her. However, because it is her home, she becomes obsessed with leaving behind. So when I went to the toilet and walked through the living room trying to cool my head, I saw her mother Kumi masturbating in the kitchen. And I was calling the name of Tatsuya. After that, when Tatsuya goes through the living room to go home, he meets Kumi who relaxes in a bath towel. And while talking, a bath towel wrapped by Kumi kicks the skin and hits Kumi without hesitation. Kumi refused, but he was pointed out to be masturbating while calling his name, and could not resist.
