I remember when I was younger, around puberty, when I was learning about myself from books, and magazines like Cosmo. I didn't know it then, but now I jknow I had a lot of build up of sexual energy.
From an early age I would enjoy touching my clit. I would walk about with my finger in my pants whenever I could. My freeloving parents didn't care.
So one day my Mom decides its time for that talk about sex. It came up naturally and my Dad wasn't home. She had just gotten out of the shower and was ready for bed, but not fully clothed...
So she discussed it, and then basically went on to say that an example is better than talking, so she showed me herself, and invited me to do the same.
Of course I ws mortified and embarresed but eventually gave in and showed her myself too. I realized at that moment I might even have a future as a nudist!
Well she gave me an anatomy lesson, pointing out the lips, external and internal, talked about the period, etc., etc., but then she pointed out that she was wet and that this was natural from all the touching of her Vulva. Mom then just started to rub her clit, and say it was her normal way of taking care of herself. She invited me to follow along, and so I did, but I didn't need her instruction as I had basically already figured out all along.
This never developed further, and was a one time thing, but if I run out of fantasy's I can always think of that day...
