I was with a friend and we were at the park talking. It was right after lunch and we saw this man walk by and then he whispered at us from the bushes. He was masturbating. He stood there with his pants around his ankles masturbating. We watched until he squirted his stuff out. He pulled his pants back up and said thank you ladies and disappeared into the bushes. We were twelve at the time in the middle of our summer vacation. It was our first sexual experience.
