My Older Sister

When I was twelve and my sister was fifteen she got me to sleep in her bed one summer night and when we fell asleep she woke up an began to play with my dick. Well I woke up and felt her slowly jerking my dick and I asked her what was she doing with my dick. She told me she wanted to feel what a dick was like and was curious about a male dick. I told her if she wanted a better experience with my dick she should suck on it and taste it. So she bent down and slowly put her mouth around my dick and even began to suck on it. After a few moments I told her I was going to cum in her and before she could say anything I shot my load into the back of her throat. She gag a little but kept on sucking it. After that I asked her if I could suck and lick on her pussy lips and she said sure. I licked her the best that I could and but before she could cum I put my penis in her pussy and began to hump her. She went through the roof with pleasure as I pumped her hot wet pussy, she pushed and grind-ed my dick in her and we both came together.
After that we found ways to get together to have sex, I don't know how she didn't get pregnant but we enjoyed this for about three or four years.
