PVC Fetish
There are a number of reasons why I like PVC and shiny latex, predominantly because of the emphasis it gives to the female form and heightens my already acute awareness of the sexuality of every female.
One of the other reasons is the sheer naughtiness of the act of wearing clothing made out of such unusual materials. It’s not an everyday fabric and even as nightwear it’s still unusual to find it in mainstream clothing. So the very act of wearing a garment made from it indicates a sexual streak and is a provocative assertion of a person’s libido.
