I play a Sign language game with the service provider at the start of the session, prior to disrobing. It may be a bit theatrical, but works for me most of the time. Play this game after you pay the House’s hour or half hour rates, and are alone with the lady in the room.
Sign language is how to play the game. It supports the fact that no spoken words occur, thus nobody can hear, nor any recordings of monetary exchange ever takes place. Just something between two consenting adults. For this just communicate silently, mouthing in the words, and make hand gestures.
I find displaying two, or three if you can afford it, twenties. One for happy ending, a second for her full disrobing, and the third for, um, if she agrees, possibly Girl Friend Experience, or whatever you two negotiate. Using voice and sound is a no-no, so use hand gestures instead. Pretend whispers maybe, but as quiet as possible.
One hand showing the first note, the other hand formes a fist and twisting wrist (the wanker). If she signals approval to that, then offer a second twenty note and silently gesture pointing to your collar or top of your head, then swipe pointing down to the floor, and or, gesture over the lady downwards from the top. That indicates clothes off, nude body to body. Swimmers like life guards, tend to swipe upwards, losing their garments while disrobing in the water.
The third twenty note is an extra, I sometimes point to or grab hold of her privates, that seems to get the message across for me. Doesn’t always get a go ahead, depends though, sometimes does.
Advanced players will talk out loud, voicing about her beautiful body, lovely hair, attractive face, or maybe food or the weather while real discussion plays out visually.
