Erika, my mother's best friend, suddenly came to my house. It seems that she had a fight with her husband, and she ran out of the house. That afternoon, I hear Erika masturbating in the bathroom. I got aroused by Erika-san's disgusting voice, and even though I knew that she was her mother's best friend, I became conscious of her as a woman. And I couldn't stand her moyamoya, so I told Erika.
