I recently wrote about something that happened this summer and was surprised that it was such a turn-on to relive it by writing about it, so I'll add my first experience with someone.
When I was 14 I used to babysit a two year old for a young couple near my house. It was usually a Wednesday and a Friday, but the Mom called and asked if I could be there on Thursday, so I went. I had the boy in his stroller for a walk and he fell asleep, so I went back to the house. I was surprised to see the Dad's car, but didn't think about it. I carried the boy into the house and put him down in his room.
I heard the TV, but couldn't tell what was on. When I went into the family room there was Mark with his pants down stroking himself and watching porno on the TV. I had never seen a real cock hard before and I had never seen porno before, so I was really in shock. I didn't know which to watch. When he saw me he tried to get up and kind of stumbled because his pants were around his ankles. I laughed nervously and then he laughed and said yeah this is kind of funny. I don't know why, but he asked if I wanted to watch him finish and I just nodded my head.
I sat by him on the couch and watched him slowly stroke his cock. Of course I ended up lending a helping hand. I didn't really know what I was doing and he ended up wrapping his hand around mine to make himself come. I was really surprised at how hard a cock really was and when he came I never thought it would shoot like that. He used his tee shirt to clean up and then asked if he could return the favor, but I said no. When I got home I practically ran to my room to rub off.
We did this a few more times that year, both at the house and sometimes in his car when I babysat at night. I did let him finger me. Needless to say I got paid more too!
