I Have Sex With My Son's Friend. Ayaka Muto

Takumi, my childhood friend who lost his father, lives alone with his mother Ayaka. Ayaka is completely different from my own mother. She's always beautiful, and my heart was pounding secretly. One afternoon, I went to Takumi's house to return a borrowed game, but there was no answer. When I went around the back, I saw Ayaka through the glass. While I knew it was wrong, I peeked for a while, and then Ayaka started doing it alone... I couldn't stand it and barged in, pushing Ayaka down.
