Sister Led Me Astray

When I was around 12 years old, still pretty naive about girls, my sister, barely 11 months older than me, lured to our basement one afternoon. Our mom was napping on the couch so she tapped me on the shoulder and motioned for me to follow her. I was busy listening to music and did not really want to follow. She kept motioning, finally pointed to her groin area and whispered, "come on, come with me". I was curious and followed here down the stairs and to her bedroom. She says we have to be quite but I want to see you naked. "Lets take our clothes off so we can explore". She was just starting to bud on top and after we got our clothes off, I noticed she had hair down there. I had a sparse start to pubic hair. She played with my dick a little bit and then spread her legs and opened her pussy up. I was amazed! She had some objects laying out on her bed and I realized later she had been planning for a bit. She had me run my finger up and down her slit and slide in a little bit. She was very wet and was an interesting smell. She had me suck her tiny nipples while I was playing with her. She spent some time exploring my dick. It was only about 3.5" long at the time but did get very hard. I remember telling her that it usually is soft. Over the next couple of afternoons, we explored more and more. She was trying to get me to lick her pussy. I was not brave enough to do that. I remember she did suck on my dick for awhile. I did not cum.
One evening, the family went to a local racetrack for a Daredevil show. While we were there, she said that she wanted me to come to her bedroom after we got home and the parents were in bed. We got home, I showered, she showered and by that time our parents had gone to bed and it was quite. I went to her room. She had found a condom in our dads drawer and wanted me to put it on and them put my cock in her. We played around for a bit and she said she was ready. She put it on me and I got on top. She held her legs open and helped me get aligned. She then had be push in. It was hard getting in but we kept trying till I finally slid in all the way. She said it hurt but to just stay there. Neither of us really knowing about thrusting in and out, we stayed the way for a bit. She finally said that I should get off her. That was when we discovered she was bleeding. She freaked out. She tried to clean it up. I went back to my room and was rather scared. She went upstairs and talked to our mom. Sis finally told mom what were were doing but blamed me for all of it. Mom came down and scolded both of us. Threatened to tell dad, which she never did. But the next after noon I got scolded again. Sis and I stopped playing around. Shortly thereafter sis became a born again Christian and went way over board.
A couple years later though, after I had started to masturbate and was able to cum, I asked her one night if she wanted to watch me cum. I asked her to show me her pussy to give me a visual to help. Just having her watch was enough and I shot a huge load all over my stomach and chest. Even got some on my face and licked a little off my hand and asked if she wanted a taste. She actually did try a little. I wanted to lick her pussy but she would not let me. Years later, when we had both gone through divorces and she was staying with me, she got drunk on night and we discussed our youth. I had a couple of female friends that had told sis about me teaching them how to squirt when they came. She did let me finger her and eat her pussy. Even got her turned on enough she squirted. Played around a couple times till she moved out. Almost had her talked into joining our step sister and I playing around. Never quite got her to join.
