I ran my hands over the sheet to his manhood and slowly played with it, letting the sheet smoothly rub on it. He threw his head back and moaned a litt...e, "yes".I crawled up further until my ass was over his bulge. I moved the dress to flow around me and laid my cheeks over his cock, letting it slip between them.I rocked slowly back and forth as a pinned his arms down.I could feel him pushing up against me with his hips.After a while, I let his hands go and pulled the sheet down over his. I changed into shorts and T shirt and lay on bed, relaxed. I felt, my wife had gone out for shopping and my son to college. I heard some music being played in my son’s room. I got up and opened his bedroom door. What I saw, shocked me to core. My son was in bed, resting on head board and my wife was performing striptease for him, top less, with background music on. She then pulled down her nicker and proceeded towards my son. He is 18 and my wife 40. She sat besides him and took him in her. Her muscles gripped me hard and she took my load of baby cream. I only wished I had more of my cum to give her that first time.No matter, Mom seemed to be pleased that I came in her belly. When I pulled out a small amount jizz leaked out of her hole. It took some minutes for my Mom to get to her feet. She went again to the bathroom to clean up. After that we went back to my bed. We touched, kissed and talked. I told Mom that I wanted her as my only lover.Mom said that my Dad barely touched her. He never mentioned girls, which Laura always found odd for a boy his age, but she knows there's a reason for it.*****Later that afternoon, Dale had arranged to play some hoops with his friends down the local park, when a large clap of thunder rattled the house, and lightning shot across the sky briefly bathing the landscape in an eerie blue light. Laura spotted him looking out the living-room window at the oncoming storm, dressed in T-shirt and shorts ready to go play. She charged out to him.
