Claire took her eyes away from the erotic spectacle and looked into mine as wantonly she cupped both of her breasts and tasted each succulent nipple i... turn.The tight velvety walls of Sarah's rectum gripped me as I began moving faster and deeper, Claire gasped as every forward thrust forced Sarah's face against her cunt and I saw the trembling beginning in her legs."Yes," she hissed. "Yes Sarah, I'm cumming, I'm cumming."She screamed and gripped Sarah's hair with both hands, her hips jerked,. "No doctor." What's wrong?"Tommi shook her head. "I don't know!" she sobbed. "I can't stopcrying!"Not knowing what else to do, Ashley lifted Tommi's head onto her lap.As Tommi continued to sob, Ashley gently stroked Tommi's forehead."It'll be okay," she cooed over and over, even as she felt Tommi's tearssoaking through her skirt and dampening her leg."I don't know what's wrong with me!" Tommi cried.Ashley sighed to herself. She really wished that Tommi would go to theclinic. She _knew_ what. After she moved out and took all herstuff I stopped. I still had the urges but never did it again. Not surehow I was able to stop but I did. So anyway that's why I'm telling you.Maybe it's a hereditary thing and I pased it on to you. Probably not butwho knows."Paul sat there not believing what he was hearing but it did help him torelax a little. But it was so weird listening to his dad tell him that hehas or at least had the same urges as he does. And that he was actuallyable to tell him this.. I heard an echo of her precious little laugh from the other corner in the back and was astonished to find a perfect replica of this vision of loveliness standing only a few feet from me and radiating the same inner glow of ripe nubile perfection, waiting for the groping hands of a young and spirited male with enough nerve to risk rejection and humiliation at her equally perfect hands.I must admit the thought of identical twin sisters popped into my brain but it was entirely unlikely for two.
