I was 13 at the time and so was Jimmy my best friend, his little sister Margie was 11. We were playing in the park one day and on our walk home we started to talk about girls we knew that we would like to fuck. Like we knew what we were talking about. Him and I had played with ourselves in front of each other lots times and had jacked each other off many times. We had taken turns sucking each other lately even tried to screw each other in the ass a few times but could never get it to work. As we continued walking and talking he ask me if I wanted to watch him screw his little sister. By know after our talking I was so horny I was ready for about anything, so of course I said yes. I really didn't think he meant what he had said but as we got closer to home he kept telling me about his sister and what they had been doing together.

They lived in a small two bedroom house and because of their young age their parents still had them sharing a room with twin beds. Well their  parents were kind of drunks so they were gone a lot at night leaving the kids home alone. Like Jimmy and I had done first touching, then feeling then actually playing with each other, him and his sister had done the same thing. So now they were actually doing it, according to him.

When we got to his house we went in mostly looking for his parents, hoping they were gone. We found Margie in their room coloring in a color book. She said the folks had gone to a tavern across town with his dad's boss and would not be home till late. Jimmy gave me a quick look and told me to go and watch TV for a while leaving him alone with Margie.

He called me back in a few minutes and told me I could watch but Margie said I also had to take off all of my clothes. Hey, I was 13 and going to get to see a
real live girl naked. They were starting to take off theirs when I got back to their room and I was undressed way before they were, standing there with my little weenie harder and longer, about 5  inches, than it had ever been. He had Margie lay down on the f look and  told her to get ready. He said I could kneel down next to them and watch, the close the better I thought.

Jimmy had left the room and came back in a minute with a little jar of vaseline. He put a gob of it on his pecker and then put some on Margie between her legs. Then he kind of moved his hand up and down sliding it all over his dick and Margie was playing with her pussy making sure it was also covered and slippery. Then Jimmy knelt down on the floor between her legs and kind of leaned over her so I could not see what they were doing. He told her to put it in for him so she put her hand down between then and did something and he said it was in. I still could not see so I tried leaning over more but there was almost no space for me to see since their bodies were so close. I moved behind them and thought I could see what they were doing and ask the to spread their legs a little more for me to see. He was moving up and down some and kind of sliding over her, but I could still not see much. He started moving faster and faster and then kind of froze stiff and gave a little shake all over.

Now with all of this going on and me trying to see what they were doing I had forgotten all about my own little pecker and how hard it was. Jimmy ask what I thought and I told him I did not really see much and did not even remember to jack off when I was watching. We were all still naked just sitting around and he ask Margie if I could do it too. She just kind of shrugged and said "I guess so." I almost came when she said that. Jimmy took some vaseline and put it on me sliding it on real good and I came all over his hand, great big gobs. Now I was really bummed out but Jimmy said don't worry Margie would wait for me to get hard again and in the meantime he would fuck her again cause he was hard and she was still horny. I watched them again but this time Margie got on her hands and knees and Jimmy was behind her. I thought he was going to put it in her ass like we had tried to do but he had her put it her pussy like before.

Now with my head on the floor looking up I could see them doing it better and saw his thing going in and out a little. He started going fast again and it came out and
he could not get it back in right and squirted on the floor and all aver my face. They both thought that was very funny, by the way. So now Margie said I had better do it soon or she would change her mind, and boy was I ever ready now. She told me to lay down on the floor on my back and she would get on top of me. I had never heard of anything like that but sure was willing to try anything to get my first fuck. She climbed over me with her legs spread wide and sat on my pecker and started sliding around on me. I said I didn't think it was in and she said it would go in a minute so she put her hand between us and grabbed me and poked me into her hole. All I could think is that I was doing it. She kept sliding around and I started hunching up with my ass, like I saw Jimmy do on the top. Jimmy then stuck his hand down by our asses and was fooling around with our butts while we were doing it. When he put one of his fingers in my butt I really started bucking her and she was pushing down harder and harder on me. Jimmy was playing with himself again by now and there we were. I was pushing up trying to stay in Margie, she was
pushing down harder and faster on me and Jimmy was jacking off and had two whole fingers in my ass. All of a sudden I started cummimg and Margie let out this big gasp and Jimmy came all over his hand. We all three came at near to the same time. My God that was great. Still naked and just sitting there Margie said I could come over again with Jimmy or alone because that was the first time she ever came and maybe it was because I not her brother or maybe it took two of us to do her enough to get some.

All of this happened in a small town in Illinois in about 1958. After that first time Jimmy, Margie and myself had many evenings together and Jimmy and I did finally learn how to get our peckers into each our asses, and Margie's, and kept this up, just the three of us all through high school and into junior collage. Now, near 60, all of us married with grown kids still sneak off and meet every now and then for an afternoon doing it and remembering when we were kids.
