Andrea had been booked for two hours and the agency knew she would phone back to confirm that she had been paid and was safely away from the client. Not that anyone worried seriously about Andrea: it was more than evident that she could easily look after herself. But, she knew, if she were ever to experience difficulties, a couple of heavies were on call.

She always thought of her clients as small men. They probably thought of themselves that way too. It didn’t have to do with height – this client was at least 180 centimetres tall – it had to do with the way they saw themselves. How she saw them. The client was in his forties, thin and pale; his suit was middle-budget, as was the hotel room. He sat on the edge of the bed, his expression a mixture of nervousness and excitement. Andrea did nothing to put him at his ease, which was as it should be. She confirmed his name and demanded the envelope with the money: Andrea always asked for cash. She checked the amount and stuffed the envelope into her bag.

‘Strip,’ she commanded and removed her raincoat, jeans and baggy woollen top. Beneath she was dressed in an assembly of black leather straps and buckles that left her breasts and genitals exposed. As usual she had done a full workout before coming out to her client and her oiled muscles were hard and sleek. The man on the bed gazed at her with an expression of awe. He was now naked and Andrea looked down at his erection with an expression of contempt.

‘Stand,’ she ordered. He obeyed. ‘You can touch me.’

The client ran trembling fingers over her body. Not her breasts or her pudenda, but her arms, her stomach, her thighs. She stood solid, firm and unresponding. The truth was that Andrea enjoyed her work; she enjoyed the feeling of power, of control, that it gave her. She knew that Cologne was full of dominatrixes, but this was something else. Her clients didn’t get off by being ordered around to clean toilets and polish shoes. This was less psychological and more physical. Her clients lusted after her body; wanted to touch her. Sometimes it would end in penetrative sex. Other times, like this, the client had asked for something very particular.

The client removed his hands but his eyes still ranged over her bulk.

‘Are you ready?’ she asked. He nodded.

‘But not the face …’ he said and his voice trembled.

‘Not the face,’ she repeated. ‘I know.’
