De Pijp, twenty-six, and a preference for the Saturday couples add to the end of a working week rather than for a weeknight.

A weekend bolted onto a work trip is a different evening from a Tuesday: nobody has an alarm set, and the session can run as long as the two of you want. Three hours at 1,080 euros is what she is asked for on those, more often than any other length. Serbian and English are both available, and she is direct in each. She lives a short ride from most central addresses, and the arrival window is forty to sixty minutes once the hour is confirmed. The content is never agreed beforehand; she sets out her own limits when she arrives and they stand until she leaves.

Danica decides which bookings she takes and may decline any of them; she sets the limits for what a session includes, says what they are, and may end a visit at any point, as the terms set out.
