I bounced up, showered the sex smell and residue off me, dressed in the cutest(and shortest)pair of shorts I had. Keep him wanting it was the surest w...ay to make him get it, if you can follow that logic. I practically had to push him out of the bed, ordering him to open the windows and shower. When he came out dressed I poured his coffee.He saw me flinch as I sat, and asked if I was sore. “Yes, but I don’t regret it. I’ll be back in business in a day or two, and the more we do it, the better it. I stepped out of my shorts and ripped my shirt off. This was beyond hot.He lay back down on the bed and told her to come squat over his face and sit down. She jumped at the suggestion, spread her knees over his neck facing the doorway and soon I could see her completely covering his face with her sex. She began rocking back and forth as his tongue kept thrusting into her juicy pussy in time with her motion. She reached down to rub her clit, something I knew she loved to do to bring on her. I shivered with pleasure at the sibling's touch and felt the copious wetness oozing into my panties as Katie ran her tongue slowly down my back and I looked across at my brother.His eyes betrayed nothing, but I knew how much he wanted me, his bulging trousers told me that much, beside him Cathy was swaying very slightly to the music and I noticed his hand moving imperceptibly behind her, she smiled at me and blew me a kiss, the night was looking even more promising.I began moving my hips in. Carol and I usually slept on our left sides with my cock snuggled between her ass cheeks and my arm around her. If we kept that same sleeping position, that would mean that Carol would be sleeping facing John or with her arm around him - anxiety. Carol leaned on her right side, facing me. She stroked my face and whispered sweet reassurances to me. She said, "This is what we wanted. I will always want you."I finally relaxed and enjoyed our all being naked in one bed together.Carol settled.
