My mother was very casual about nudity during my youth. She often left the door to her bedroom open as she dressed or undressed.
I would wander in and engage her in conversation as I stared at her body. Her figure was not perfect, but she never failed to make me hard. I loved to watch her breasts jiggle and sway as she dressed or washed herself in the bathroom. Her nipples made me crazy with desire. They were large and usually erect, like they were begging to be sucked. I used to think about her swollen nipples as I jerked off after ogling her body.
She sometimes sneaked a glance at the erection she caused. I wonder if she ever thought about me while she masturbated.
