I peeked at my relatives' older sisters changing clothes after not seeing them for a while, and they invited me to take a bath together. They showed off their grown-up bodies, and we washed each other. I got an erection, and she noticed it, pretending to wash my dick but actually gripping it. When we were kids, it would end with doctor games or pranks, but I'm an adult now. I don't care if my dick goes into her wet slit!
