Most of the time mls don’t dare to offer. The moves actually made by the male customers. If doing well extra, make sure that he finishes before his wife. I used to do for a wife, and even though I didn’t know the husband did or not, I still gave her an extra time to make sure she finished later than him.
Story 1: the husband somehow recognised the clinic is actually RNT so he “asked “ the girl by body language. The wall even does not go up to the ceiling.
Story 2: the husband let his wife waited outside and in the room he asked for sex. Of course no one wanted to give that extra so finally he left. Such a husband!!!!!
