Once while roaming around the house i found grannys room locked from inside. I opened the door and found nancy on the bed wearing a G-string with her ass facing the sky. I have seen nancy naked many times so it was not a problem for me to see her like that. Hey son, what happened, i was just getting my monthly massage done dont panic said nancy. Not now but sometime later granma i said and walked away so that i could hide my huge erection. Later that day i saw nancy in the kitchen. Nothing granny, all fine i said. Dont look at your granny like that son, its not good, she said while Walking away.
