I'm having sex with my son's friend.

Takumi, a childhood friend who lost her father, lives with her mother, Ayaka. Ayaka is very different from her mother. It was always beautiful and I was excited inside. One afternoon, I visited the Takumi's house to pay back the game I had borrowed, but there was no response. When I went back, I saw Ayaka through the glass. I thought it was wrong, but after peering around for a while, Ayaka started doing it on her own... I couldn't stay there, so I came up and pushed Yaka down.
