I sneak in a small rub while she has me turn around. "My god, I have never felt anything that sensual in my life," escapes my lips.The slip is careful...ly lowered over my head. I never knew that slips could be so ornate and sexy. I try to look at it from every angle possible. As I hold the material in my incredibly beautiful hand a wave of femininity passes though my soul and I find myself on the verge of swooning. I would never have bought anything so gorgeous for myself. "I would never buy. Err, would you like a beer? We've got plenty in our cooler." Girls, it would be my pleasure to sit down to a brew or two with you." And he moved closer to them. Nancy moved to her knees and opened the cooler, popped a can of Bud and handed it to him. He gulped about half down, then wiped his mouth with his arm."Thank you." He burped, not loudly but it was obvious that the girls had heard him. "Excuse me. That was a welcome from my lips to my gullet. They needed that." Oh go on, everybody does. Mark let out a moan and ran his hand through mom’s short, mousy blonde hair. His other hand rubbing mom's bushy vagina.After a short while, mom raised her head, leaving a loud ‘pop’.“I want your cum inside my pussy!” mom purred to Mark.I had never heard mom sound so dirty! It was almost as dirty as her cheating on dad with her own brother.Mom propped herself up onto the headboard, her arms outstretched. Mark shoved his penis inside her and sawed in and out. The strict, frigid mother who had. The age difference might be to much? Finally I just said, "Hey, I've gotta go, would you like to come up to our room and have drink and sit around with a bit more privacy?" "Uhh, sure", Jeff said. I could tell he was taken aback, but to his credit, he didn't bolt. As we made our way to the elevator and climbed to the room, my inner voices raged. "TELL HIM! ASK HIM! EXPLAIN TO HIM!" None of it seemed to make sense and so I just let it go, knowing once we were all in private that we would have.
