Sienna lives in Oud-Zuid among the quiet avenues that run south of the museum quarter. She often takes bookings from guests who stood in galleries from opening time and came back with their shoulders held high and tight. Warm erotic oil is her usual format, and she likes a two-hour booking when the evening is free. Italian and English are the two she speaks. At twenty-seven she is elegant, soft-spoken and exact about her limits, which she gives before she begins. A two-hour evening with her leaves time for the oil to reach the feet as well as the shoulders, and the pace stays slow from the first stroke to the last. Pressure is agreed in the opening minutes and changes with a single word from the guest. Nothing is added to her fee for a Sunday or for a booking that starts late, and every figure on her page already includes all taxes.

Sienna 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.
