I couldn't wear mom's things so I bought my own.
I was bigger than my mom by age 12 . Initially I might borrow some of mom's panties but she didn't have any pretty one's. I found my big sister's panties because they were nicer. By the time my fetish was full blown, none of the things fit me. So I was forced to purchase them myself. Buying pantyhose wasn't too difficult because in those days LEGG'S PANTYHOSE were common. I could wear Q size SHEER ENERGY PANTYHOSE. I sometimes got looks of curiosity from girls who thought I might be buying them for myself. They weren't very hot usually.
I enjoyed wearing the silky sheer pantyhose and masturbating.
