One time on a date, I went on a trampoline with a guy

His cock came flying out of his shorts and he was uncircumcised with a long foreskin that flapped in the wind. I grabbed it and stretched him out to his limit then let it snap back like a rubber band. I kind of want to put a weight on it so it stretches him even longer until his foreskin dangles down to his knees. Am I wrong for this?
