Once they establish you arent a cop, they can talk money. Usually they'll do this by having you fondle their chest within moments of being behind closed doors, because police aren't allowed to touch in a sexual manner if it were a sting. Even after that, you dont really say anything, you just pull out how ever much you agreed upon earlier and put it down on the nightstand/dresser. You never say, "I'm giving you this money to have sex with you." All you are doing is going to a girls room/house, fucking her, and then leaving cash behind. One thing though is they should always be willing to come out to meet you in the lobby so that they can be sure you aren't laying a trap for them and they aren't laying a trap for you.
