I couldn't believe what I just heard. I swallowed hard as my throat had run dry and managed to say, "Are you serious?" "Completely," was all Mary said... "Don't worry, this is just going to be between you and me. We're all alone here and they won't be back for at least a couple more hours." With that, she swept away the pillow she used to cover herself up and gave me a complete view of her body. Her breasts, while small, were perky and had nice nipples. The were obviously hard and ready. She. She ran into the room where I kept the washing machine. I heard it turn on only moments after she went in. I shrugged again, although I was curious why she was so concerned. Before I could wonder any more, a very embarrassed-sounding Kelly called from behind the door. "Danny...?" Yeah?" Can you PROMISE not to laugh or do anything bad or ANYTHING?" Sure..." I responded without hesitating. Kelly cracked open the door just a tiny bit, and just stuck her head out a bit. "You sure...?" she squeaked.. Sam's coming out now with the girls to take them to their friend's house."Steph muttered, "I'm going to my room for a while."She didn't look exactly happy. Aunt Lois cracked a beer."Want one, Ben?" Yeah, I sure need something."She handed me mine and promptly proceeded to divest me of my shirt and tee. Then she removed her own top and bra. She next removed her skirt, half slip, and panties to stand in front of me bare ass naked again."Now your shoes and pants, Ben."She helped, grabbing a solid. After draining my balls dry, she leads me by the hand to her bed and says “Now I’ll show you how to fuck me like a man”. When we get to the bed room, I sit on the edge of the bed and mom gets on her knees and begins sucking on my cock until it is hard as iron. As she continues to work on my cock like a staved whore, I stand over her and watch as I fuck her face in a continuing pumping action. After a few minutes Mom slides up on the bed and spreads her legs. She is hot and wanting me to slide.
