I read Childhood Turn-ons & it reminded me of some from my own childhood.
A lot of times in school there were teachers (young & older) who turned me on, as it were. I went to a private elementary/middle school where the girls were required to wear either pantyhose, thigh high or knee high stockings & that was always a big turn-on for me as well. My mom has always had nice legs & they're accentuated when she wears pantyhose. She used to changed in front of me all the time & thought nothing of it. Once her friend came over to our house to change for a party that they were going to where they worked & they both changed in front of me as though I wasn't in the room. Her friend looked so good that when they left I masturbated thinking about what I'd seen.
