This happened about 30 years ago but still too good to forget.
Let's start the story by me telling you I had been getting myself off for about a year and a half after Pete a friend had shown me he could cum when he jacked long enough. I tried too and had orgasms but no cum but I practiced steady for about two weeks it finally happened. Wow I practiced a lot more after that.
Anyway I spent a lot of time at a friends called Tom. Due to me being an only child and parents divorced. Tom had a younger brother Dave and sister Janey.
One day we were a few doors down from their house playing basket ball with other kids. There was a girl named Marcy that teased all us horny boys by dressing in too small tank tops and short shorts. She was a well developed 16 year old redhead not too pretty in the face but a body to make up for it. I would guess c cup with perky nips and a beautiful ass.
Marcy was at it as usual bouncing around and rubbing up against us as we played. I don't know if on purpose or not but I was in agony that day because I hadn't jacked the two days I had been there. I had gotten hard the second time and could not take it any more so I told them I was going to get a drink and go to the bathroom. As soon as I got there I went into the bathroom to jack off cause no one was home. I just gave the door a push and went to work on my hard dick.
I was aiming at the toilet as I stroked my shaft and rubbed over the head as I went over the top I could feel a load building as I gently rubbed my balls. I grunted as a couple of spurts splattered the back of the toilet. As I was squeezing out the last of it I noticed movement at the partially open door. Oh shit it was Janey. That sinking stomach feeling came over me as she ran to her room and slammed the door.
Well I figured she would tell so I cleaned up in a hurry and went to see if she was calling her mom but when I peeked through the key hole she wasn't at the phone, looking around the room I could see her feet and spread legs on the bed moving around. I thought guess I'm off the hook but continued to watch and it didn't take long for me to figure out she was fingering herself. My dick needed more attention so I pushed down my shorts and started to stroke again trying to see further up. I rarely thought of her sexually but I was about to blow another load when I heard the back screen slam just shoved it down and pulled shorts over it.
It was Tom the game had broken up we went into the living room to watch tv and Janey came in after a while she looked different to me besides being red faced and sweaty looking. I shot a fast glance at her and she kind of grinned at me. About that time the phone rang Tom said Janey get that she said no. I figured I would leave so I said see you guys later. Tom said it's probably mom get it, she still said no so he got up and went to get it. I started to get up and she said are you goin home so you can jerk off some more WOW that was a surprise but I came back with no are you gonna go finger your self some more she was suprised but not like I thought.
Still grinning she said when you leave meet me at the fort in fifteen. Still in shock I agreed and left. More to come.
