Caught in the buff
I remember sun bathing in our swimming pool with my cousin Susan. My brother had invited his friend from high school over for a swim. We were working on our tans, when my brother came out of the shower room laughing with towel and a bunch of clothes in his hands. He wanted to prank and told us "why don't you both walk in on him" They idea of catching his friend naked in the shower was tempting. Told us he would be so embarrassed he would never tell any one and to hurry up before he found out. It was prank so why not have some fun. I remember we caught him shampooing his hair with his eyes closed, stark naked and looking at his d***. Never seen such and embarrassed boy when he heard Susan say "nice d***" and turned around to see both of us checking him out. Sexy and arousing because he had no clothes, no place to hid and plenty of time to check him out. I still remember his d*** creeping up on him and ending up with an embarrassing full erection. Funny because after we've seen it all, we said sorry and walked out.
