I was 14 (iirc) and once when at my girlfriends house, found myself getting a bit nosey in her and her sisters room while she was downstairs.
One of the draws had a selection of bra's and knickers in it, and one pair immediately caught my attention. a very sexy and shiny pair of red panties.Obviously at that age I was unaware of what type of material it was, but without hesitation I just found the urge to take them - yes, I feel bad about it!!
A few days later when my parents were away, I just couldn't wait to try them on. I was so excited. Once I had them on, I felt such a rush and wanked myself silly in bed wearing them.
A few days later, my girlfriend was quite angry. Apparently her sister had accused her of taking her underwear!
Since then, I have always had a huge silk/satin fetish and love mostly wearing the lingerie. Love full-back panties, crop tops, french knickers, cami sets, and I love french maid outfits too. I find satin skirts a big turn on, but blouses don't do anything for me unless I'm also wearing the same lingerie.
It used to be such a major issue buying silk/satin lingerie before the internet came along, I'd walk through the lingerie dept of a shop such as Debenhams, M&S or similar and get so nervous, but that just heightened the pleasure overall once I'd actually managed to buy some. Nowadays, it's so much easier to buy stuff without having to go through the trauma of being served by a very cute/sexy assistant..and wondering what she may be thinking!
Now if only I could get a girl involved and film some of my silk/satin fantasies!
