She finally quieted down and this time he put one of his heavy legs over one of hers then pushed her down to where her back was on the couch and bent ...ideways. I chose not to look then on, because I knew she had won once again, and that I was left their to exist in the background once again. Then out of her sniffles Loraine let out a loud scream and I looked over but I couldnt see anything but her panties around her ankles which were now completely on the couch and from what I could tell held. Rolling to the side, I noticed the beautiful face of my sister Stacy, and the pervious nights activities came back to me. Let me explain.Stacy and I, along with our brother and sister, Shane and Stephanie, are quadruplets. My name is Shawn by the way. The previous night we had gone to the senior dance at school, and then came back to have sex with each other for the first time. Our parents were gone for the weekend, so we had no problem with being caught. Both Shane and I were a few inches over. This ended when the guy shouted "When's your whore going to strip then," "Right now then," I said looking at Marcia. She did not need to be told again and got up and walked to the stage to a load of whistling and cheers. She climbed up on to the low platform and as the music began to gyrate her body to the beat. After a few minutes she began to remove her clothes. First her top showing off her lovely tits, then her skirt. For a while she danced around in just her tiny red thong until to a round. Neither was possible, of course. And whenever we were together, our appetites for each other seemed insatiable. The satisfaction of our hungers was possible sometimes but not always. We learned to accept the situation because each of us had been raised in a relatively puritanical family culture. Divorce as a solution, for instance, never arose as a topic in our conversations about our mutual problem and frustrations. But we did become more inventive in our schemes to find private time together..
