Me and my little sister have always been super close, and not shy about showing our love and affection for each other. Kelly and i think and feel exactly the same so often that words are sometimes superfluous. If I am feeling something then its almosrt a given that she is feeling the same way. This made it easy for us to satisfy our sexual curiousity early on, casually and without inhibition until puberty came and the sexual focus was shifted to forbidden trysts with boys (and sometimes girls) outside the home. The horny little kids became horny young ladies.

 By the time Kelly had graduated from HS she had developed into a smokin hot babe. Big firm boobs, bombshell body and angellic face, she carries herself with poise and grace and oozes sex without even trying. We have always teased each other and flirted, and last year the flirting started getting serious, and the sexual tension between us became an 800 lb gorilla in the room. We both wanted it, and of course we both knew that, and with our sexual attraction growing by the day, the only question was how and when it would happen.

 Last fall found kelly and i going to the same school again for the first time in 2 years. I drove her to school every day, and we started spending more time together than we had since HS. The sexual buzz between us began to reach critical mass, and when kelly turned her prodigious charm and powers of seduction on, that was it, I decided i would make it happen at the first opportunity. This decision changed my perception of kelly from hottie baby sister to soon to be sex partner, something she picked up on immediately and radiated back at me. Our excitement and sexual energy was reaching a fever pitch when the gods smiled on our incestuous little souls.

 Kelly and i got home from school one friday just as our mom had finished packing. "whats up?" we asked her. "Didint i tell you? Im going to visit my sister. Ill be home sunday evening." Kelly and i looked at each other with the same expression that we used to get on xmas morning. We had the house all to ourselves for the weekend! Mom had barely gotten out of the driveway and i was running around locking doors and closing the drapes. Kelly sent a text to her friends that she was sick and would be staying in all weekend, and i did the same. I broke out some of our holiday champagne and we polished it right off. 

 Kelly straddled my lap facing me, a huge smile on her pretty face, her teeth so white, such a fresh and irresistable little delicacy. We looked into each others eyes, expressing without words our incendiary desire for each other. We kissed and passion consumed us. I dont know how long we kissed, but it was indescribable, and when we finally broke the kiss we literally tore our clothes off and locked into 69 on the floor, with her on top. We orgasmed almost immediately, in unison, then engaged in the most intensely pleasurable sexual ecstacy imaginable for an indeterminate amount of time. The outside world disappeared and we experienced what i can only describe as a non stop orgasm the entire time. The earth shook and galaxies collided, and when we finally came to our senses we were panting, faces soaked and hair matted with each others pussy juice, reeling in epic afterglow euphoria. We disengaged and looked at each other in wonder and disbelief until we had to laugh. I knew it was going to be good, but this was a level of pleasure that i didnt even know existed. It was natural, beautiful and left us absolutely in love, closer than ever. Nobody can tell me it was wrong, it was simply nature taking its course.

 Once we caught our breath we took a shower together, rubbibg our soapy bodies together and washing each others hair. We were to exhausted to do any more than that. We blow dried each others hair and then slid into bed together and fell asleep with bodies intertwined. It was only the opening act of a weekend long passion play.
