What about phoning to see if they do any extras? Are prices agreed halfway through usually or at the end ?
Things not to do if looking for extras
Dont ask them over the phone, this goes back to, the police might be trying to entrap them
Dont ask the receptionist, same thing, police
Dont ask the girl directly, wait till se prompt you, how ever if you ask the girl or even the receptionist, your massage will end there and then
Things you could try
Leave your hands down by your side, and touch her legs accidentally, if nothing said, like move your hand away, try feeling her legs
If she does credit card swipes "wipes her hand between your ass cheeks"
Only then should you consider asking her
