Do you feel that they actually see the cash as a generous gift, and are in fact fucking you for free?
Or is this just one of your kinky fantasies?
Picture two scanarios for setting up the mood.
1. Here is an envelope. Girl grabs it runs to the other room. you get undressed she comes back you are pretty much undressed and all goes on well.
2. Man gets out wallet. Asks how much.
Ok, (man licks his finger and thumb and goes); £10, £20, £30, £40, £50, £60, £70, £80, £90, £100
Man hands over just counted money in a clenched fist and drops it into the girls hand.
Girl tries to grab all the money and not to drop any of it and then walks out of the room with all the money to put it safe.
