Sherlock stood at the top of the stairs and beckoned him to come up.

"Its okay, my flatmate's out."

"Flatmate?"

"Yes. Colleague."

"Right." He looked around the flat. "Nice."

"Do you want a drink?"

"Got any vodka?" Sherlock poured a double into a glass.

"Do you want anything in it?"

"No. Neat is fine. What time is he due back then? This flatmate of yours?"

"A couple of hours."

"Okay. I charge by the hour."

"Of course. How much?"

"Two hundred. An hour."

"That's expensive."

"I'm very good. I'm sure you'll think it's worth it. So what do you want me to do?" He started peeling off his clothes, revealing the strong body underneath. Sherlock swallowed nervously at this predator in his domain.

"I want you to f*** me. Hard. Make me come."

"Does this flatmate of yours do that for you?"

"None of your business. Now F*** me."

He was rough. Pushing Sherlock down on the bed, tearing his clothes from his body and pounding into him. But there was no denying it was fantastic. And exactly what he'd been asked to do. Sherlock wished he could see the expression on his face, but that wasn't included in the price. He banged three Orgasms out of Sherlock, whispering obscene endearments in his ear the whole time. Then he stopped.

"What was that noise?"

"Nothing."

"It's not your flatmate come back early? I'd hate for him to catch us like this. I think he'd be very jealous."

"Yes he would be. And he's an ex soldier. He has a gun."

"Doesn't frighten me."

"Really?"

"You still got half an hour. What do you want to do?" This time he took Sherlock slowly, facing him, but still with that air of controlled malice in his eyes which said I could really hurt you if I wanted.

He rolled off of Sherlock, closing his eyes very briefly, catching his breath. Then John turned to face his flatmate.

"Okay. Next time we do this. I get to be the client and you can be the rent boy. Okay?"

"Okay. And John? You are definitely worth more than two hundred an hour."
