I'd gone to the shop and my daughters friend had accompanied me, she was about 19, the weather was blazing, we walked slowly back home chatting. In the distance walking towards us was a young guy, ginger haired, in very short shorts and a vest top. I'm myopic and as he neared us I was sure what I was seeing was just some strange effect of my faulty vision, I tried to look more closely while appearing not to look. I glanced at my friends daughter, she was smirking, we looked at each other and burst out laughing - apparently unblissfully aware of it this guy was walking along, his cock dangling out of the leg of his shorts and about four inches of it waving free in the glorious sunshine. We couldn't stop laughing hysterically, but he passed us by seemingly not knowing it was his dick that had tickled us so much. Was it possible he didn't know guys, or if your dick's floating free do you always know?
