There are so many stories on here about brother and sister mutual masturbation. Here's another
Well, to start off. This happend when I was 15, and my big brother was 17. I started masturbating when I was 13.
I have a fantastic body. and always had, I loved to tease boys wherever I went. I noticed a bulge in my pants whenever my brother was around me. I had nice little 38B tits, and a nice round butt. One night as usual I was teasing my brother and just asking him if he was hard and other things. I went and sat by him on the couch and was sure he had a good view of my tits. I had a very low cut shirt on. Then before I knew it he had his fingers on my slit just stroking it for a few minutes.
Then I grabbed his hard dick through his jeans and kept rubbing it. He slipped one hand up my shirt and was caressing my nipples. He was truly good at this. By now, I had his hard dick in my hand and was stroking the shaft up and down. Fast then slow then medium. He of course had two fingers in me by now. This continued for about 10 minutes, it was silent.
Then I started talking to him. Telling him I was his whore, and he was my pimp. He had total control of me, and other stuff. Then he started breathing really heavy and grunted, and he came, all over my stomach, tits, and some on my pussy. He shot at least six ropes of warm sticky cum.
Then he focused on me, he was fingering me as hard and fast as he could and then all of a sudden I came. He was calling me his bitch, and only he could have me. I came so hard, I had never cum before. My usual orgasms were same old same old. But his fingers were covered with my juices. Which he later licked off. We did this every Saturday night after our parents had gone to bed. Until he went off to college. He now has a wife and two kids. But we still tease each other every now and then.
I hope you liked my experiences.
