My mom (48) is divorced and stays here with me. She has been single for 10+ years.
One night, i heard noises and went to look, and saw her door open. She was on her bed half-naked playing with herself. Her night dress was open from the front, her bra pulled down, erect nipples and boobs so full. It was a sight to watch. Her thong was pulled down and she was playing with her pussy. Her eyes closed, she was enjoying herself making mild moans and grunts.
I stood there and watched until she hit her orgasm. I rushed back to my room.
