Openly posting that a girl will do fs is stupid.
The amount of guys viewing this that will expect to walk in and get fs for $200, regardless of what the lady wants is asking for trouble.
If its gonna be a brothel and everyone who walks in gets fs, just say so.
And good legs do not make a foot fetish. Legs and feet are not the same thing just cause they are attached. A lady can have great legs and awful feet and vice versa.
