I hadn't seen my cousins in a while, and I wanted to see their naked adult bodies, so I peeked at them while they were changing. Then I was invited with 「Want to take a bath together?!」 While we were washing each other, it got hard. At this age, you want to touch, lick, and put it in, right! I took the opportunity when we were alone, and we went into the bath together. From washing each other to touching each other, of course I inserted it!
