It was an effort not to stare as she knelt down on the living room carpeting commenced playing with the younger children. In my mind's eye, I was able...to see her sliding down her tiny thong and revealing a smooth crotch.I recalled the sight of her lifting the hem of her dress and straddling me. A second later I was treated to the feeling of my cock pushing into her tight wet pussy and the moaning sounds she issued as I penetrated her.
