Caught my mom masturbating

I am an Indian guy (25) living in Australia. My mom (48) is divorced and stays here with me. She has been single for 10+ years.

Recently, 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. I am filled with guilt and regret.
