I did this in the park once. I was sitting on a long bench and a guy i had seen walking earlier came and sat by me and started talking. He sat so close our legs touched. He pushed his hairy leg against mine and i pushed back. he started opening and closing his legs, pressing against mine each time. I could see his bulge, it was so hot. Once in a while he would subtly brush his hand against his crotch. My eyes were transfixed. He put his hand on the crotch of his shorts and fingered his growing bulge. He pushed harder against my leg. As soon as be took his hand off his crotch i replaced it with my hand. I gently massaged him and he was completely hard in no time. I stuck my hand down the waistband of his shorts and pulled out his hard, throbbing member. I started moving it up and and gently. He reached over and was massaging me through my shorts. Before too long he was wiggling all over the bench and i had a sticky hand. About 10 seconds after that I came in my shorts and underwear. It was a totally hot scene that i think of often. Like now...
