So did you use the condoms? Or what were they for?
Out of interest, what do you usually say to bring up extras in advance of starting?
Just in case the lady is interested in my offer of another £40 for full service on top of £20.00 for happy ending. I know it’s getting up to a hundred for an hour, if I can afford it at the time. I prefer the mixing a sensual body to body massage with full service session than just an escort full service session.

Side note, twice I had thigh and butt cheek in-and-out session without fucking, and that’s pretty good alternative to full service without the sensitivity reducing condom. Once was years ago, and once was recent, review later.
Back to your question about what do I say. When the service provider enters the room ready to start the session, that is when my “up selling” pitch begins. I say very little, mostly show the first 20 note and wave my fist back and forth up and down with the whisper word “Happy”.
If she accepts that note, the next higher offer of a second 20 note goes with with the gestures to drop all of her clothing, whispering or silently mouthing “Body to body”. If that’s accepted and she takes the note, I say thank you very much and indicate a full service gestures of various type.
Since we are both standing next to each other an I am starkers, I bring out the third and final 20 note, occasionally with a unopened condom. Then with my other free hand, I reach for her pussy up front, or groin area via her behind, and gently pat or rub or touch the sensitive spots gently without mouthing nor saying anything.
Often times without the visible condom she may ask me for one, or she may provide one herself, running out of the room for a moment, returning with one wrapped in paper. I guess that must be a Chinese thing, I prefer them wrapped in foil!
