Is this considered an extra?

Don't have a foot-fetish and would never think to have that done, but I don't mind a woman's tongue anywhere on me

Wash your feet first!

Yes it is. It is extra gross

I really don’t care if that made the guy happy. But I hope she got paid a handsome fee for giving him his fetish fix. Personally I find it gross and sort of stupid - but we all have our oddities - I would much prefer to throw a tongue around her beautiful nipples.
Some thing are just better not videoed or photographed. The written or verbal description is usually sufficient to gross a person out.
Just saying.....

Well... Now we know another smelly place that a stripper's mouth could have been on the custy prior to you!

Some peeps are into feet; not me.
