My married cousin came to stay at my house after a fight with her husband. She treats me like a kid and enjoys my reaction by showing me her panties. When I went to peek at her in the bath, she invited me to join her and we washed each other. She squeezed my rock hard dick with her mouth, saying, "Don't tell mom." I was about to get caught by my mother, so I stopped and waited for everyone to go to bed, and then I continued my sex education in my sister's room where she was sleeping, teaching her body to me.
