So Andy went around at five o'clock and could smell a lovely aroma as he walked up her driveway. He saw her standing in her kitchen and she seemed to ...be wearing even less today than she was the day before. She then bent down to check on the roast. Andy just thought to himself that she should stay in that position so he could take her from behind. His cock got hard even thinking about it."Hello, Carole. The roast smells great. The last time I had one was when I was living at home."Soon. Uncle Bob was holding her mom's arms down on the mattress and kept driving his naked backside in between her legs like he was spanking her with his body. Sheila was no stranger to spanking because she had been a naughty girl on more than one occasion.Her mom kept shaking her head from side to side and hollering out "no" but she could tell she really meant "yes" because she was giggling and laughing as well. Uncle Bob must have known she wanted him to continue as well because he suddenly started. I asked in a firm voice what she was doing, she got scared and immediately started sobbing and said that she did not know it was already there in the pc and started begging that I should not tell mom.Her guilt made me for excited and I saw this as a perfect opportunity hence I said that there is only one way to resolve this she would have to do whatever it was showing in the videos only then I wont tell my wife all this hearing this she got confused so I went near her and explained her it was. After a few moments she began to sway her hips from side to side causing the cheeks of her arse to rub the thong together between them. As I watched, hypnotized by her curvaceous movements, I had to reach down and readjust my stiffening cock in order for it to sit more comfortably in my trousers. Without realizing I was doing so I gave it a little rub which felt incredible as I fantasized about taking her from behind. She walked into the room and disappeared from sight. Without even thinking.
