A 50-year-old public housing complex built during the period of high economic growth. The neighbors have known each other since their parents' generation, and everyone is positive and warm. In this apartment complex, in this family home where I was raised for 20 years, I perform immoral acts in secret from my mother. I don't indulge in luxury, I wear modest clothing, and I don't use editing apps. She's not flashy, but a full-sized girl who is bright, cheerful, and has a good personality. On a weekday afternoon, we have a lot of sex. The moment I see her fluffy, unprocessed pussy with a shy smile, I burn with desire. A perverted sexual fetish where I get wet when I think about what would happen if my mother found out. Once I climax, all that's in my head is "I love dicks," "I want a dick," and I shake my hips myself and become erotic. A raw gem discovered in a certain mammoth apartment complex in Itabashi Ward.
