I'm having sex with my son's friend.
Takumi, my childhood friend who lost his father, lives alone with his mother, Ayaka. Ayaka is nothing like my own mom. She's always beautiful, and I'd secretly get all flustered whenever I saw her. One afternoon, I went to Takumi's house to return a game I'd borrowed, but no one answered. Going around back, I saw Ayaka through the glass. Knowing it was wrong, I peeked for a while. Then Ayaka started touching herself... I couldn't stand it anymore. I barged in and pushed her down.
