Making a booking and do a door check. Remember you can always walk away if is not willing to agree or you sense she is just only giving you a rush service.
Do you kiss them before or after you cum on their face?
It just seems an odd combination to complain about, French Kissing being more of a GFE thing and COF being a PSE thing. How often would you do both in the same booking? Personally I don't get why anyone would want to COF; I just seems totally degrading to me but each to their own I guess.
Also if you're doing both COB and COF is that 2 shots or 1 big one that sprays everything including the walls?
