Due to waterworks, the pipes in the neighborhood were broken, and the entire area was cut off from running water. Luckily, my house was safe, but my sister's friend who lives nearby came to our house and asked if she could use my bathtub. Our bathroom had become a women's bath at a public bath! Unable to resist, I peeked at my sister's friend's naked body! However, just when I thought she would get angry if she found out, she said she wanted to see me naked too... Of course, it didn't end with just looking, and the atmosphere became erotic and we did it. It wasn't just peeping, it was sex!
