I think if I was booking three girls, I’d see it as a very special treat and be prepared to spend a good amount. I’d negotiate a flat fee for each for a longer more relaxed session. 3 hours, £350 each plus provide drinks.
That said, I’d be more concerned about finding three girls where the chemistry worked and what exactly I was going to do with them. Get the chemistry right and the fun should just flow, as opposed to having a check list of things you wanted to accomplish.
