Mine was in high school long story short we had a pool day. One of the guys in my class idk why I always kinda felt weird about (later found out why lol) was changing and he was wearing nylon adidas pants no underwear🤤 he pulled his pants down and his cock showed and it was so yummy looked semi hard and it just turned me on so much watching it shake and bounce around as he pulled his pants off and out his shorts on 😩
