Why do you love panties?

I have had my share of skinny girl and wondered what's with the cotton panties?I mean most of the girls I dated wore the cotton.I finally got the notion to buy my girl some satin panties.I explained to her that the cotton ones were ok but I had a fetish for satin ones.Rubbing "it"on cotton didn't do it but satin get "it"going and she looked sssooooo sexy.She started wearing them for me when she wasn't on her monthly and I wish I had taken pic.

I only wear them when i'm under the influence of a certain drug to masturbate
