A/N – I don't know what to say… This fic is because of and dedicated to "SC".

When Mrs Hudson said she wasn't their Housekeeper, she meant it.

John had no idea. Sherlock did, of course, but the army doctor was blissfully unaware that Mrs Hudson ran a school for people who wanted to improve at being submissive before they started it with their partners. That was the true purpose of 221C Baker Street. It was where lesson one took place. Lesson 2 was in 221A and included making tea, food and working with shackles, handcuffs and other bondage tools to do anything possible. Lesson 3 was cleaning and other duties in 221B; though not very many people stayed for Lesson 3, it was a dangerous business.

Occasionally, Mrs Hudson would call in outside Doms to do the gritty things and teach the subs how to work with sexual gratification and commands. She had two main male Doms; one was Sherlock and the other a guy called Anderson, who never gave his first name. She also had a quiet seeming lady Dom called Molly. Sherlock didn't know about her though.

Today, she had a young man called Alex. He'd bravely decided to move onto Lesson 3. Sherlock was refusing to leave his flat and so was taking the lesson there. Sherlock had decided to strip down to just tight black boxer shorts and a small black mask. Alex slowly climbed the stairs to 221B, and was suddenly regretting his decision. He bolted to the bathroom and locked the door, breathing heavily.

"Come on, Alex. You've made it this far. You can move on to the harsher side of things, just- just- grow a pair, get changed and do as Mrs Hudson has instructed you. It's simple." He took a deep breath and slipped out of his suit, neatly folding it into a bag. Then he pulled on a leather gimp mask, a small dog collar, tight PVC pants and took out a bag containing shackles and a lead. He nodded briefly to himself and walked out into the living room. Sherlock was waiting for him, hand outstretched for the bag.

"Ah, Dimmock. Nice of you to make it to lesson 3. Thought you might have got lost."

Alex froze, gulped nervously, handed over the bag and then dropped to his knees. He bowed his head, awaiting orders. "Why did it have to be Sherlock?"

"I will address you as Alex henceforth. You'll address me as 'Sir' if spoken to. You'll obey any commands I give you. What is your safe word? Speak." Sherlock got bored of this bit, but it had to be done.

"S-scones, sir."

"Ah, one of Mrs Hudson's favourites. Very well. You may begin by scrubbing the floors. I shall attach the leash now." Alex turned dutifully around; it was easier to keep the link at the back. "I have prepared the bucket and brush. Aren't I kind? Speak."

"Yes, sir. Very kind, sir." Relax, Alex. Mrs Hudson warned you that he will get violent, just relax, you can do this. Neither of you will mention it next time you see each other. He waited for the command to move. Sherlock shook the lead and he crawled over to the bucket, waiting for the next tug before starting to scrub away.

Sherlock got bored of this, so he tied the leash to the kitchen table and proceeded to sit and watch Alex's shorts moving around. That is to say, he sat and watched Alex's bum.

"Are you nervous, Alex? Tell the truth."

"Yes, sir."

"Have you ever sucked another man's cock?"

Alex froze. "No, sir." He forced himself to relax and keep scrubbing the floor. The scrubbing was the easy bit. He wasn't against giving a man oral, he'd just never found himself in the position to have to give it.

"Have you ever been whipped?"

"No, sir."

"Have you ever stripped from your tight pants and touched yourself for another person?"

"No, sir."

Sherlock paused, considering him. He wanted Dimmock to come back for another lesson; he didn't want to start too heavily. He loved it when a member of the police force ended up in his living room. He loved the power, loved making them beg.

"Have you ever watched someone else touch themselves in front of you?"

"No, sir."

"Interesting," thought Sherlock, "a little goody two shoes."

"I want you to strip for me."

"Yes, sir." Alex stood up and carefully removed his pants, making sure not to get tangled in the leash. He tried his best not to feel too nervous in front of Sherlock, but he wasn't doing very well at that.

"Do you like me being in charge, Alex? Like the lack of power?" Sherlock was walking round him in a large circle. He was playing by different rules to normal, but then, normally he'd have some boring business man or a secretary. Something dull, someone he wouldn't see again. "Like the fact that I'm in control of your body? That you've no decisions to make? That you wouldn't be allowed," at this Sherlock moved up close behind Alex and whispered sharply in his ear, "to cum, without me saying so?"

Alex took a deep breath. "Yes, sir."

"Feeling aroused, Alex?"

"Yes, sir."

"Want to be touched?"

"Yes, sir." Alex was trying to keep the subtle layer of desperation out of his voice.

"Beg, Alex." Sherlock stood in front of him, holding a long stick with a small leather Spade on the end. He tapped it slightly against his own palm. "Beg and I'll consider touching you with this. Don't beg properly and I will hit you with it, 5 times. Understood?"

"Yes, sir. Please sir." He dropped to his knees. "Sir, I crave nothing more than to be touched, my body craves your approval. I am worthless, nothing without your say. The only thing that matters is your word. Please may I be considered worthy of your focus?"

Sherlock walked around to the back of Alex. "Bend over." He leaned forward onto his elbows without a second's thought; all he wanted was to be touched, even if it was just the harsh sting of a whip. He gasped suddenly as he felt the whip gently sliding along the inside of his thigh and then again on the other side. He quivered, his head dropping to his hands, needing more. His body jutted slightly as Sherlock stroked along the sensitive flesh with the whip and his legs spread slightly. Sherlock half smirked, adjusting his eye mask. "Sit up."

Alex did and stared at the whip slightly longingly. He'd not really understood it before, not completely, but boy did he want more.

"Are you ready to go further, Alex?"

"Yes, sir. Whatever you crave, sir." Sherlock smirked and Alex gulped. This was it, he was committed to this lesson now.

A/N – So, what do you think? Are you ready to go further?
