Who can join

So she's 4 or 5 guys and only charges for one? Sounds like a no brainer to me

Any lady that agrees to that request clearly has no brain.
Very dodgy to put it mildly.

What lady in her right mind would do that? Jesus no!

One who made too I'd imagine

Why not if she is getting well paid for it and she knows were she is going and a good idea of who will be there. It is highly unlikely that somebody would come onto a public forum and arrange this sort of thing with a view to carrying out any illegal act. Clearly ground rules would need to be established e.g. can more than one be involved can guys watch etc. Clearly anyone just blindly agreeing to a meet up like this without checking up on the bone fides of the participants is silly but if they get assurances and get a good pay day why not. Danger nearly always comes from an unexpected source.
