I met my cousins for the first time in a while, and when I was peeking at them as they changed clothes, I wanted to see them naked, and they invited me to take a bath together. When we washed each other, my dick got hard. At that age, we have strong sexual desires, so we want to touch, lick, and put it in! We waited for an opportunity to be alone, and we went into the bath together, and washing each other turned into touching each other, and of course I inserted it!
