The duration ladder is the house price list read as a sequence of lengths: time is the only thing priced, because time is what a slow session is made of.
Most massage menus price the technique. This one does not. Tantra, lingam, yoni, sensual, nuru and every other named technique cost the same for the same length, and the district, the hour of night and the day of the week make no difference either. The house calls its price list a ladder because each step up is a longer span of time, and the price rises with it evenly.
The first rung, sixty minutes, costs EUR 180. Half an hour more brings it to EUR 270; a second full hour, to EUR 360; a third, to EUR 540. Past that point each further hour adds EUR 180. The last rung is the overnight: a flat EUR 1,250 covering eight hours, not a tally of them.
With two therapists the hourly figure doubles to EUR 360. A pair for two hours comes to EUR 720, and for three, to EUR 1,080. The ladder has no overnight for two therapists, and none is quoted.
For a slow technique the lowest rung is rarely the natural choice. An hour exists on the ladder and can be booked, yet most tantra sessions are placed at ninety minutes or two hours, because the opening and the close cannot be compressed without losing the pace that defines them. The ninety-minute minimum entry explains that working habit, and the two-hour guide describes the length most clients settle on.
The rung also bears on the deposit. Once a booking reaches three hours, half its price goes ahead, whoever books it; a pair of therapists brings the same condition at any length. Current figures always appear on the price page, which is the reference if anything here and there should ever differ.
