A signal to let him know that she wanted up.Bill gave each of her nipples one last suck before releasing her breasts as he slowly slid off her body. S...tting up, he stared out the window away from Lisa as she crawled off the bed.Lisa grabbed a rag from the night stand, crusty from the night before, and quickly placed it against her pussy to catch the fresh cum dripping from her pussy. Damn, she was going to have to change the sheets yet again.Bill was still staring out as Lisa came back in the. I saw her look straight into my eyes as she realized what I was about to do. I knew it would be easy for her as wet and aroused as she was at the moment. “Just relax sweetheart.” I kissed her and slowly entered her wet steamy pussy, inch by agonizing inch. I stopped when I felt her cherry. I looked down into her eyes, she nodded her head slightly and smiled up at me. I pushed inside her and felt her cherry give way to my throbbing cock. I stopped to let her get used to the invasion and realized. ( I later this was called the 69 position). As we sucked he again pushed two fingers in and out of mybum and I got more and more excited. He took his mouth from my cock and said "I am going to come so you come in my mouth" The feeling in my cock and arse built up and up and as I felt his cock pulsing in my mouth and I came in his mouth. We slowly stopped moving and although our cocks came out of our mouths he continued to play with my bum. He finally stopped but by this time my cock was. Over the next six months I saw them in almost every room in the house. Each time he was slamming it into just as hard as he could and she was begging for more. I guess what hurt me the most wasn't that he and Mom were having sex but he was giving it to her in a way he wouldn't with me. I mean I was always begging him to pound me but he would always be gentle. Finally the other day I caught them again and decided I'd have enough. They had just finished when I walked into the bedroom. Mom was.
