The old UK Hot Lips had separate pages for feet, PVC and leather, and general fetish. They all live on one line now, staffed by women who are genuinely open-minded and don't need anything explained twice.
Foot fetish
Shoes, stockings, bare feet, painted toes. A surprisingly popular call, and one the women on this line are very comfortable with.
PVC and leather
The look, the feel, the sound it makes. If you've got a thing for shiny black outfits, she'll describe hers in as much detail as you like.
Roleplay
Set the scene and she'll play her part. Nurse, boss, neighbour, stranger on a train: it's your fantasy, and you're both adults.
Anything off limits?
A few things, by law: nothing involving under-18s, real people, animals or non-consent. Outside those, the women on this line have heard most things and are hard to shock.
