My Mother exposed her breasts to me

First time was a brief “flash” but got my interest. I also noticed her eyes as much as her breasts. Was that alluring or mischievous?
The next time I saw my mother’s breasts we were both standing in front of her dresser mirror. Mom unbuttoned her blouse. When it opened I could see her bra. Mom dropped the blouse from her shoulders then reached behind and unhooked her bra. When she took it off I was staring at her naked breasts in the mirror. They were not really large, maybe C cup and they had the sexiest sag one could imagine on a woman of 63.
She put some talcum powder under each breast. I noticed her arm pits were very hairy which added to my excitement. Then we kind of stood there looking at each other in the mirror. My dick was getting hard as I stared again at my mother’s saggy breasts. Mom asked me if I was was embarrassed to see her like this. I said maybe a little but I was fine with it. She put on a clean bra and finished getting dressed. I went to my room and and jacked off imagining I had reached out and fondled my mother’s breasts.
