My sister and I were home alone. In the house next door the family had a pool and their son and his friends sometimes went swimming. That afternoon there were several boys using the pool. We could look down at their pool from my sister's room.

We watched, not having any thing else to do. The boys started playing around and then one by one they took off their swim trunks and were swimming naked. It was really the first time we saw naked boys who were our age. They were all between 14 and 16 and my hand was between my legs fingering myself. I got going pretty heavy and playing with my clitoris, leaning on the window sill watching the boys by the pool. I had this orgasm, first time that I felt the control of my legs go away and my sister had to hold me up.

It was several weeks later when we were talking to the boy next door that we had seen him and his friends naked. How we got around to asking him to show us his penis I don't really recall. It was a lot of kidding and me offering to pull down my pants if he pulled down his pants. He pulled his pants down first and I had to follow. I touched him, I took his penis in my hand and touched him and asked him if he liked it. I let him touch me, he just put his fingers on the outside. I kicked my pants off and sat on my bed and I put his penis in my mouth and sucked him. He got his pants off and I got up on the bed and laid back and opened my legs and he got on and found my vagina and we had intercourse.

He didn't pull out, not that I asked him, he just fucked and when it was time for him to cum he came inside. After he pulled out I sucked him again.

We were not really officially boyfriend and girlfriend, he was in the ninth grade and I was in the seventh. My sister was in the fifth grade. I convinced her to show us her stuff, got her pants off and laid her back on the bed and opened her legs. I put my mouth on her and sucked on her and used my tongue to open her pussy. Her pussy was swollen. Our neighbor was erect again and he got on her and had intercourse with her and like with me, he came inside, pulling out only after he had completely left his load in her.

He liked having his penis sucked and I told my sister to suck him. Night began to fall and we got dressed before our parents got home. He left out the back door and went around the block back to his house.

Our adventure that afternoon could not go unsaid, and we told this older girl at church that we had intercourse and were no longer virgins. This girl was in the tenth grade and she was the one that really put the fear of God into us for letting him cum inside of us. My sister wasn't really into her periods yet, although she had them irregularly. My periods were more regular but still not quite every four weeks.

Starting about three weeks after we had intercourse we started counting days and waiting. I didn't get my period again until almost a month after we had intercourse, my sister went for eight weeks before she got a period again. We gave him blow jobs, anything oral, and let him feel us up and go down on us, we allowed him to penetrate us, but we were careful to just let him penetrate and do a couple of strokes and then pull out and use us to rub his penis on us before he came on our stomachs. Later we learned to lay on our stomach and let him use our butt crack to rub himself into an orgasm.

At a football game when he was a senior, we got caught with me giving him a hand job in the stands. We got caught and there were lots of people around us, he had his jacket over his lap. After that we had to go public with becoming boyfriend and girlfriend. We went to prom, and were serious daters. By then we had intercourse regularly and he had intercourse with my sister pretty regularly as well. We had gone the route of condoms, but once we got the pill we were 'on' for just about any time and took care of him if we were inconvenienced.

My sister got pregnant first, she was 22 and had been out of college for a year. Since she was pregnant, they got married. I struggled with getting pregnant or not. He was married to my sister and she was expecting her second child, and I struggled emotionally. When I turned 30 I gave in and finally had my child, by that time we had been having intercourse for more than half my life. What started as a form of dare has become a pretty serious affair. He and my sister are a good couple. I am sure she is a much more committed wife than I would have been.
