The duration ladder sets the fee by length, by one therapist or two and by one client or a couple, from a single hour up to a whole night for a couple.
After dark, prices elsewhere in a city tend to drift upward: taxis surge, clubs add a door charge, the late menu costs more. The ladder here does not move with the clock. An hour at four in the morning costs what an hour at seven in the evening costs, and the figure is the same for every neighbourhood, every day of the week and every technique.
For one client with one therapist, measured against the single hour:
A single client with two therapists, or a couple with one, pays double each rung up to three hours. Their nights part ways: the single client with two therapists pays eight doubled hours in full, while the couple with one pays twice the one-therapist night, which is less. A couple with two therapists pays four times the base for every rung, and twice the two-therapist night for the whole of it. Hours past three always cost that row's own hourly figure.
Length is really a question about pace. One hour suits a late, decided mood, the kind that follows a long dinner and already knows what it wants. Ninety minutes gives a slow beginning room to breathe, which is why so many first bookings land there. Two hours lets the evening forget it is being timed. Three hours and beyond turn a visit into a night out that happens to stay indoors.
When a booking carries a deposit, the deposit is exactly half the rung: three quarters of the base on a first ninety minutes, the base itself on two hours booked a day ahead, three times the base on three hours of two therapists for one client. The rest is paid when she arrives. Every therapist profile repeats all four rows in its own rates table, and the overnight entry treats the eight-hour block on its own terms.
