John smiled as Sherlock's eyes flew open, indignation flaring in his pupils.
"What's the matter, Sherlock?".

The detective was panting heavily. "Please let me come, Sir, I need -"

"You need what I give you. Deep breaths for me now".

John watched as his submissive complied, noting the clench in the detective's jaw. He wondered how long it would take before the frustration became too much for him.

They remained in silence for a while, Sherlock's slowly steadying breath the only sound in the room. John watched as the glow of Sherlock's skin receded slightly and the thickness of his cock depleted. He waited patiently until Sherlock's shoulders had stopped shaking before leaning forward to capture his lips in a kiss; the man barely responded. John traced an idle hand down Sherlock's torso, pausing to rub the pad of his index finger lightly across one of his nipples. Sherlock's breathing hitched at this gentle touch and a quiet noise somewhere between a whimper and a moan caught in the back of his throat. John took the hard pink bud between his fingers and twisted firmly, his own cock throbbing with desire at the whimpers his actions produced. He did the same again, and Sherlock's whole body jumped, but he made no effort to try and force himself from the doctor's grip. In fact, John was sure that Sherlock was pressing his chest into his hand, a silent request for more.

"Are you enjoying this, Sherlock?"
On the detective's failure to reply, John took both nipples in his hands and twisted, hard, forcing an answer out of his submissive.

"Fuc-yes, sir".

"Good boy" John murmured. "Do you want to come, Sherlock?".

Nodding frantically, the detective replied, "Oh God yes, please sir...". His voice was cracking and he emitted a guttural moan as one of John's hands moved to his aching cock. Lube was an irrelevance of the past, and John began fisting Sherlock's hard length at perfect pace, his eyes gleaming.

"How badly do you want it, Sherlock?"

"Please god don't stop, please sir - I need to come, I need to -fuck!"
"But this is a punishment, and bad boys don't get to come..."

Sherlock's eyes were squeezed shut, half sobbing. "No, god, please I've been good, I'll be so good, just..."

"Don't you dare come without permission, young man."

John was amused at how desperate Sherlock had become, how he had been reduced to begging, and how his behaviour was so far from its usual self that it seemed a different Sherlock Holmes entirely was kneeling in front of him.

"Fuck sir, please may I come?"

John shook his head but didn't stop the movements of his hand.
"No, Sherlock, don't come. It will be worse for you..."

Sherlock shook his head, moaning incoherently. "It won't be worse, it can't be-". His mouth remained open but no words escaped. His whole body stilled as his orgasm took hold, cum spurting onto John's hand, the feeling of release almost painful from his prolonged state of arousal. After a few seconds, his eyes slowly focused in on John, whose face was a mixture of anger and amusement. He held up his cum-stained hand to Sherlock, who looked at him with pleading eyes.

" I told you not to come" he lectured. "Lick my hand clean".

Sherlock's pale skin was a bright pink and his stomach swirled uncomfortably as he reluctantly obeyed, licking the tepid fluid from John's palm. He felt dirty and a little repulsed at himself. John was still looking at him with half-amusement.

"I told you it would be worse if you came , Sherlock..."

With that, John grasped the detective's spent cock and swiped his thumb roughly over the overly-sensitive head. A shock of pain wracked through Sherlock's body, and he struggled to remove himself from John's clutches. His position entirely forgotten, both hands came down and pushed against John's shoulders, his legs trying to force himself up and away.

"Fuck, don't!"

John had predicted this, but instead of trying to force Sherlock back into position, he started pumping the detective's sore cock, sending shivers of horribly uncomfortable electric into Sherlock with every move. His spent cock was sensitive to even the lightest touch, and John's manhandling of it was utter agony. The submissive stilled, the pain clear on his face, seeming at a total loss of what to do. His hands clenched, grasping at John's shirt, his breaths short and sharp, hissing in through his teeth.

"Don't! Ah-let go! I can't..."

John slowed a little, but continued to idly stroke along the shaft, paying special attention to the extra sensitive head.

"Too much for you, Sherlock?"

Sherlock could barely speak, shuddering and trying to squirm out of John's reach, sobbing uncontrollably.

"Y-yes too much! Stoppleasestop".

John administered a particularly aggressive stroke, and Sherlock yelped, hissing in pain and desperately pushing against the doctor, although his predicament had weakened his strength considerably, and John simply ignored it.

"You know, I don't think I've been addressed properly in a while, have I?"

Sherlock growled loudly, frustration and panic clearly setting in.

"Sir!Stopsirpleasefuckyou'rehur-Oh God, stopfucking..."

John's fingers continued to stroke relentlessly along Sherlock's cock at an agonising pace. He had Sherlock exactly where he wanted him, begging and pleading, almost at his absolute limit. The doctor was aware of the time constraints of this punishment: Sherlock would eventually get hard again, so he needed to finish up and get his point across before it turned into a game of how many times Sherlock could come in the space of an hour. He'd save that for another day.

"I think the swearing needs to stop, too, Sherlock. Naughty words shouldn't come from such a pretty mouth, understand?"

"Yesssirsorrysir. It's too much – I can't" Sherlock was beside himself, past anger, past frustration. He'd never felt so helpless, so in pain, and all at once. "SirIreallycan't,please, I can't!"

"Yes you can, you have to. Back in position, Sherlock, and stay there until I'm done with you." Beads of Sherlock's sweat and tears were dripping onto the floor, and the submissive shook his head violently, panic in every syllable "Ican'tdon't make me.."

John was merciless. "You asked me to punish you, Sherlock" he reminded him. "This is what you wanted, so do as you're told."

Sherlock's legs slowly spread, his hands untangling themselves from John's shirt at returning to their place at the back of the detective's head. He looked at the doctor, his eyes filled with hurt and something that vaguely resembled hatred. His teeth were tearing and grinding against his lower lip as he forced himself to stay still.

John was impressed. Still stroking, he looked at his submissive.

"So, what have we learnt today, Sherlock?"

He waited patiently while the detective collected himself, the resentment growing in his eyes.

"T-to answer your questions, Sir"

"That's right" John continued. "Anything else?"

The blush in Sherlock's cheeks rose. "N-not to come with permission...Sir".

The doctor smiled. "Correct. And I've decided that I'm not going to tolerate your embarrassment anymore. Next time you take forever trying to ask me something, I'm going to make sure it's as embarrassing as you seem to want to find it. Understand?"

Sherlock stifled a growl. "Yes, Sir".

"Good boy." And with that, John released Sherlock's cock from his agonising grasp. The detective immediately gasped for air as if he'd been holding his breath for hours. His whole body relaxed and he pulled his legs out from their kneeling position, and laid down on the vaguely damp floorboards, eyes squeezed shut. John sat and watched the rise and fall of Sherlock's chest as his breathing pattern returned to normal. The detective lay very still, his body seeming oddly long when stretched out on the floor, and did not move.

After half an hour of silence, John assumed he had fallen asleep, and began to rise off the floor to leave. Just as he straightened up, a long pale arm reached out and grasped gently at his ankle. Without opening his eyes, Sherlock addressed him.

"I moved."

For a second, John was entirely confused. Sitting back down, he took Sherlock's hand in his own.

"I'm sorry?"

Sherlock turned his head towards the doctor and opened his eyes.

"I laid down. I'm not supposed to move unless you say so, but I did, and nothing happened. You didn't do anything. Why?"

John sighed, brow furrowed, tracing patterns on Sherlock's hand as he considered the question.

"It was pretty cruel, what I did to you. You were at breaking point, and I was sure that one too many orders and you might... well. I think in light of the severity of your punishment, your disobedience could be forgiven under the circumstances."

Sherlock nodded slightly, before turning his head back towards the ceiling.

John cleared his throat, concerned. "Just out of curiosity, how was it?"

Sherlock smiled thoughtfully. "Horrible. Not being allowed to come wasn't so bad – merely frustrating. But, continuing to touch me post orgasm... I never ever want to do something that deserves that punishment, again."

John chuckled, a teasing tone in his voice "Well, you did disobey me several times during the punishment. So, technically, shouldn't I start the punishment over?"

Sherlock's eyes widened and he stared at the doctor, as if trying to deduce how serious the man was being. "But sir...please, no!"

John laughed and let go of Sherlock's hand in favour of returning to the sofa. "I think that would kill you. But I'm definitely using that punishment if you come without permission ever again. Seem fair?"

Sherlock huffed and sat up, crawling towards John and climbing onto the sofa with him, his head settling on John's lap. "I don't think fair's the right word for it, personally..."

John took hold of one of Sherlock's nipples and twisted, and the detective yelped in surprise.

"That's enough backchat from you, young man."

Sherlock wriggled uncomfortably and mumbled a rather pathetic apology under his breath, distracted by the soothing sensation of John's fingers threading through his untamed curls absentmindedly.

"Sir..?" Sherlock started casually. John mmm'ed in reply, seeming far more tired than perhaps the detective thought he should.

"Did you mean what you said? As in, you'll deliberately make me feel embarrassed if I act embarrassed when asking for something? Is that right?"

John shifted slightly underneath Sherlock and frowned. "Yes, Sherlock, I meant it. There's no reason for you to be embarrassed about being submissive, and so when you act in that way it makes you seem...ungrateful. And I simply cannot allow that behaviour".

Sherlock sniffed. "You simply don't allow ANY behaviour, Sir".

John sighed. "I've told you before, Sherlock, you have some terrible habits"

Sherlock smiled, a glint in his eye. "But I'm improving?"

John grinned back, a little sleepily. "We'll see...".

This chapter somehow ended up a bit fluffy, but I kinda like that their relationship is developing on an emotional level as well as a sexual one. To those who have noticed that John hasn't actually gotten off yet...perhaps this will be addressed in the next chapter.

Please review, what were your thoughts on post-orgasm torture? I thought it was an appropriate deterrent for coming without permission, but I'm also aware of huge step between a firm spanking and masturbation torture...oh well. Hope you enjoyed it!
