I had been approximately 12 or 13 - A former neighbor visited my parents for the weekend. She had been a terrific beauty!!! My mother hung some of her extra clothing over the inside of my bedroom door. Example, a silk slip, blouse, etc. I felt myself touching the fabric, then kissing the silk slip..LOVED the aroma. As like the panty / bra dresser drawer of my mother.
Would wear the form fitting bathing suits of my mother - when I had been home alone.
Nothing like the feel of a short silk slip rubbing against my panties.
I think my mother always knew, although we never discussed it (wish we had).
