When I was 16, I worked at a restaurant with a bunch of other high school aged kids. One of my co-workers, Jack, lived near the restaurant so he would occasionally invite me back to his house after work to hang out. His parents were always asleep by the time we got off work at night.
One day, we were playing cards and I made some comment and Jack said 'suck me' which was a typical sarcastic reply amongst our friends. I was always somewhat attracted to Jack but didn't think he felt the same since he was very good looking and he always had a steady stream of female dates. Half joking, I said 'Sure, whip it out.' Jack said 'Ok, let's go to my room.'
At Jack's room, the lights were off and he was laying on top of his bed. We had to be quiet since his parents were sleeping up stairs. Through the moon light in the window, I could see the bulge in Jack's pants. I slowly pulled down his pants and underwear and he his dick was rock hard.
I started sucking on Jack's dick and he came within minutes. I then asked Jack to suck me off. He did and I came quickly. Jack commented how large my penis was and asked me to suck him again. I did. He then sucked me off again. We both spewed cum all over.
After that, we both seemed a little embarrassed and we never spoke of it again. It was a fun time and I wish one of us would have had the nerve to say so and continue with that relationship.
