Risky, but best orgasms ever.
Me and my sister have been doing the naked nasty since she was 13. Normally, I never put my bare cock inside of her pussy, because she's not on birth control. Last weekend, our parents were away, and we were going at it in my bedroom. I asked her if I could fuck her without a rubber, and she said okay, as long as I pulled out before I came. I pulled the condom off and slipped my bare cock up inside her. Her pussy was so tight and hot and wet that I came after just a couple of minutes. My little sister felt so good wrapped around my cock, that I couldn't even think of pulling out, and she grabbed my ass and pulled me tight against her while I came. She orgasmed at the same time I did, which she had never done before.. I pumped what felt like a gallon of cum inside of her dripping wet pussy. I collapsed on top of her, after what was the best orgasm in my life. She told me that we shouldn't have done that, but she said it felt awesome feeling my bare cock unload inside of her. It was the best orgasms we have had together, but we know it's to risky to do it again. I'm hoping our mom will let her start on birth control so I can cum in her every time.
So my little sis and I fooled around a bunch of times when we were kids. Over time it gradually went from some kissing, touching, some showing, a few incidents of oral. It wasn't until we looked at porn sites on my lap top that we actually had sex. She was to young to get pregnant so it wasn't an issue but like when she had her first period, by then, we both knew we had to stop.
As adults we just don't talk about that period in our lives, like most siblings with that kind of history. It was what it was at that time of our lives. We were very, very lucky we did not get caught because there were a few times we took some big risks and had two close calls with getting caught yet it did not stop either of us. It was something we both willingly did together and it's in the past.
I want a little sister so bad!
I think exploding into your mommys mouth or ass or pussy is the best orgasm ever, because she is so skilled to pleasure her little boy. we started very young and I dont remember the earliest times but I definitely remember screaming deliriously thrusting in her mouth.
I initially used condoms with my sister because like your situation my sister was 13 as well. The pill is the best answer though.
Good for you two!!
