When I was 15 I caught my 13-year-old brother masturbating in the bathroom. He was embarrassed but I told him to continue. I liked to see his pink tip sliding in and out of his foreskin. I sat on the edge of the bath and told him to stand right in front of me. I touched his penis and it felt hot and hard. I started to wank him like he had been doing... Massaging the shiny tip through his foreskin... He started breathing faster and making thrusting movements ... Then his sperm shot out, thick and creamy... There was lots of it all over my face and hand...
