Bike shorts and tourist (50M)

OK, so I am about 50 (M), good looking, penis size is definitely above average, and in better shape than most college guys. We have a bike trail that goes out into a lake. When no one is around at the end of it, I like to position my cock so it goes down the side of my leg and get it semi hard. I pretend to look around when other people are there and have caught a few women staring and got a few smiles. Pretty amazing some looks I get with women who have hubbies or boyfriends there. I love teasing them with my big cock.
