How I wish it happened to me more often.lol
At 16 I was an avid masturbator. I used to go to a buddies all the time and we talked sex. He was a couple of years younger. I used to put my hands in my pants in front of him all the time. One day he shocked me with a question. He asked if he could watch me cum. I agreed with great enthusiasm. I had a spot in the backyard with some privacy. Also it was dark out.
We went outside and made sure the coast was clear. I then dropped my boxers to my ankles. I began to play with my stiff cock as he watched and stood beside me. I took my time and played with it a good half-hour or more. I soon told him to watch closely as I was close to cumming. I turned to him the second a shot flew out. He watched my cock until the very last drop fell. I loved it and wished to preform for others.
