When two people book one escort in Hong Kong, the arrangement in the room has a shape, and the trade writes that shape as two or three letters. MMF means two men and a woman; FMF means two women and a man. The letters are not decoration: they say who is expected to do what, and an escort reads them before she reads anything else in the message. A couples enquiry that never names the configuration is asking her to agree to an evening whose shape has not been described.
Four arrangements sit behind the word, and an advert usually means one of them.
Not all of the 91 profiles here mean the same arrangement by it, which is why the letters get written out. A unicorn, in the trade's own word, is the escort managing two people with different expectations at the same time and keeping neither of them idle. That is the skill behind the word, and it is why women who are good at couples bookings say so plainly instead of leaving you to guess. A woman who has not done it before is not necessarily the wrong choice, but she will normally tell you, and the honest answer is worth more than the word.
Two people booking together often disagree about this without discovering it until the evening, and an escort cannot fix it from inside the room. Settling it in the enquiry — all three present throughout, or one of the couple stepping back — turns a vague booking into a specific one and lets her say honestly whether she works that way. An evening built around two women instead of a couple changes what has to be agreed, and girl-girl bookings in Hong Kong cover what changes when the second woman is being paid too. Couples who want the evening to start slowly and stay unhurried often book it as a session for two hands or four, which an erotic massage instead covers technique by technique.
