This happened when I was 16
Thanks Helen for opening this topic. Incest/Family fantasies are only normal I think.
Anyway, to my story. I have four brothers, two older and two younger. One summer afternoon I was out by my pool with Jimmy (an older brother 17yrs) and Steve (a younger brother 14yrs). I was kind of celebrating because I had just gotten my drivers license. My parents were at work and we put out all the ice cream we could find. Hyped up on sugar we began to get a little wild. I was laughing and jokingly suggested we all get naked and get into the pool. Before I knew what was happening Jimmy was naked and doing a cannonball into the pool.
Well after a little while we were all naked in the pool. It was so exciting seeing my brothers cocks. I was getting wet, and not from the pool. I began to rub myself below the surface of the pool. Steve noticed and swam over next to me and began to rub his cock. Jimmy noticed and came over and joined in. The next thing I realized Jimmy began to rub my leg and then my pussy. Steve began sucking on my tits. I was tense at first, but then relaxed and let them do what they were doing. Five minutes later I had the biggest orgasm ever. Looking around I wasn't the only one as I noticed sperm in the water.
This was the first time, but definately not the last.
