AN: Please note that this chapter is a little smutty. Prompt by the lovely mummapaintstheblues:

Rokudaime Kakashi has carpal tunnel syndrome, Sakura, his physician, has to explicitly explain what actions he shouldn't be doing.

"I fought the scourge of the Seven Swordsmen, you know," he said grumpily, watching as Sakura unwrapped the box of dango with undisguised glee.

"Zabuza," she replied, lifting herself onto the edge of his desk, legs straight out in front of her as she rotated creaking ankles. "I remember, I was there."

She didn't sound suitably impressed - fair, he thought - and put a hand on his chin while he frowned at her under his silver bangs. It was hard to stay disgruntled at the beautiful woman in front of him, especially when she darted a pink tongue out to catch a stray drop of syrup, but he tried. He tried very hard.

"Sakura," Kakashi declared, forcing her to look at him with a smile on her face that hovered around the edge of amused. "I was a General in the war. I led thousands of other ninjas. I was there when we all saved the world."

Listing off his achievements, the Hokage watched with narrowed grey eyes as Sakura nodded along placidly to each announcement.

"That's you alright, Kakashi." Vixen. There was a definite air of tease to her tone now, but he refused to budge just yet, staring down the woman he'd shared his heart with as she contentedly ate the dango he'd caved in and bought her (again).

"I'm the Hokage." Skirting the edge of a whine, Kakashi watched as his girlfriend rolled her shoulders and neck, satisfied puffs of air escaping her lips as they cracked horrendously.

Both of them were as busy as they ever were and then some, thanks to the Chuunin exams returning to Konoha and causing an alarming amount of paperwork to begin piling up in their respective offices, their living room, and sometimes even the bedroom. Kakashi had taken to "long baths" to avoid the sight of it, but Sakura hadn't complained; rather, she'd joined him on several occasions, which tended to result in even less work getting finished than usual.

So now, he felt rather justifiably betrayed at the way she was smiling deviously at him over the remains of her dessert.

"I hadn't noticed, Rokudaime-sama," she murmured, using the tone of voice he'd explicitly banned her from using during working hours. For several reasons, not the least of which was the uncomfortable stirring below his abdomen at her husky tone.

He cleared his throat, willing his pulse to stay stable. "So then," he ground out, "tell me why I've managed to get carpal tunnel syndrome? And why you can't just fix it?"

Sakura pursed her lips, aiming for innocent but looking anything but. Kakashi slid his eyes from her to the door of his office, noticing she'd locked it as she sauntered in earlier. Fighting down a smile, he leaned back nonchalantly, closing the blinds with a swift flick of his uninjured wrist.

Now considerably darker, the temperature in the room seemed to heat up a few degrees as his personal medic shuffled closer along the edge of the desk, placing one deceptively dainty foot on the very edge of his chair.

"Well, Kakashi," Sakura started. "You get carpal tunnel when you… vigorously strain your wrist doing certain activities. Repetitive activities."

At her explanation the silver-haired kage's eyebrows rose, unable to clearly make out the expression on her face as she spoke. Over the past two years he'd discovered Sakura had varying levels of tolerance for seduction and he sensed she was probably fast approaching her first limit, so he was surprised when she continued.

"Unfortunately," she said, sounding anything but sorry, "carpal tunnel syndrome affects the nerves in your wrist, and I'm far too drained of chakra to attempt to deal with the nervous system at the moment."

That probably wasn't entirely true.

"Hmm…"

She waited while he considered the next move, setting down the dango tray and wrapping both hands under her bare knees. He knew as well as she did that he'd likely strained it with all the signing he'd been forced to do over the past few days; but where was the fun in that?

And outside of whatever game they were playing at the moment, she knew very well he'd have to be unconscious or incapacitated to let anyone else but her heal him.

"I'm afraid I don't particularly understand what… activities I could've been doing that would cause this," he paused, watching as Sakura's vibrant green eyes glittered, "so could you explain for me? In detail?"

"So I don't do it again," he added, enjoying the way the blush was creeping up her neck now that his sight had adjusted to the dark.

"Ah," - and Kakashi recognised she'd gone as far as she could because her face was his favourite shade of crimson - "well, you've…"

There was a pregnant pause.

"Instead of explaining," Sakura said suddenly, and his eyes went wide as saucers as she kicked her shoes off and placed one squarely in his lap, "let me show you."

Forget limits, this was completely uncharted territory: despite her protestations, his girlfriend was at heart a good girl, the kind who enjoyed fun but preferred it to stay in their bedroom. In their years together they'd never, ever exchanged more than heated kisses when outside the privacy of the Hokage residence, and never in the middle of the day.

Certainly never in his office.

He swallowed heavily, sliding his mask down when her intentions became clear. Moving slowly to give her every chance to change her mind, Kakashi slid his pain-free hand up the back of the leg currently pressing deliciously into his groin, bypassing her hand with a quick caress before sliding under the hem of her loose shorts.

When she simply wiggled her toes sinfully, stoking the heat below his navel to a fever point, he smirked and moved to touch the tips of his fingers against her underwear.

Sakura didn't let him go further. At the first brush against what was definitely not cotton she shifted away from him and levered herself down onto her knees, pushing his legs apart with clear intention.

Maybe, Kakashi thought as she settled between his legs, maybe he was dying.

"Um," he managed.

Her eyebrows rose questioningly, face tantalisingly close to the peak in his trousers where she'd teased him. When he simply shook his head she curved her lips in a secretive smile and without further warning hooked her fingers in his waistband and pulled.

"Movement like this," she said clinically, curling her fingers around his suddenly exposed erection and demonstrating, "can cause the nerves in your hand to strain themselves."

Kakashi swallowed, feeling strain of an entirely different kind. Sakura between his legs, stroking him absent-mindedly as she stared into his eyes with a devious grin, was the stuff of his fantasies. When she twisted her wrist and her fingers danced across the sensitive skin he wondered how far she planned to go, twitching a little as thoughts of her bent over his desk surfaced.

"Are you listening?" Sakura's head was tilted to the side innocently, green eyes shining at him through the dim light of the office.

He nodded, not trusting himself to speak. At that, Sakura looked satisfied, shuffling closer and sliding her free hand up the leg of his trousers, shifting playfully over his knee and resting close to where her other hand was working.

"To avoid aggravating the nerves it's good to alternate," she continued, switching hands and holding back a laugh as he hissed at the change in temperature.

Gripping the arms of his chair - because it seemed like she wanted him to stay still while she explained - Kakashi watched with dark eyes as she teased him. And just when he started to feel the familiar heat burning in his abdomen his girlfriend suddenly shifted forward on her knees, licked her lips, and pulled him into her mouth with a smile.

With the last of his faculties Kakashi considered whether he'd already died and was currently enjoying the afterlife.

"Oh, god," he moaned.

"Nope," Sakura said around him, the vibrations of her voice doing wonderful, terrible things, "just Sakura."

He bucked his hips in retaliation, enjoying the indignant squawk he received in return. There was a moment where he was already cataloguing the day as one of the highlights in his life when Sakura's hands slid up his torso and suddenly, awfully, his blood ran cold.

He hadn't expected to see her until later that day. Hadn't thought of the need to hide the not-so-inconspicuous small box in his chest pocket. Sakura was in many ways an unconventional girl, but he didn't think that extended far enough to finding out he was going to propose to her while she was on her knees doing unspeakable things to him in his office.

There was nowhere for him to shift away to and she'd obviously felt him start to go soft in his panic; she frowned, looking up and pulling away completely at the obvious dismay on his face.

Kakashi was torn between feeling grateful that her hands had retreated before they incriminated him and feeling depressed that she'd moved certain other parts of her away from him too.

"I'm, I'm-," the medic started, seductive confidence fleeing at the look on his face, "I'm so sorry, was that too much? I just…"

She was flushed in the way that Kakashi knew meant that she was deeply embarrassed.

"Oh, oh," he stuttered, realising that of course she'd misinterpret his pulling away. "No, it was great, I-,"

There was a beat of silence where he pulled his trousers back up and she sat on the ground looking forlorn. Pulling her unresisting form up until Sakura was square in his - rapidly responding - lap, Kakashi sighed into her neck, careful to hold himself so she wouldn't feel the ring box. Disliking the rigid way she was holding herself in her embarrassment, he stroked a soothing hand down her back, breathing in her unique scent while she allowed him to comfort her.

"Was I bad?" she whispered.

He couldn't resist nipping the soft skin under her ear. "No," he growled.

"Then…"

Kakashi sighed. "If I tell you, you have to promise not to be annoyed."

An instant passed when she considered. "I probably will be," Sakura said honestly.

"Mah, you probably will," the Hokage agreed. "But…"

He shifted, unwinding an arm from around her to fish in his pocket.

"I've been planning that for days," Sakura sounded slightly sulky and he smiled secretively.

"I've been planning this for days, too," he replied, pulling out the small gold box and holding it where she could see. "But I didn't think you'd appreciate finding out while you were…"

Grinding his hips up into the beautiful woman on his lap, Kakashi grinned at the way her gasp of surprise trailed off into an unbidden moan.

"Is that...?"

"Yes," he answered simply. "Now, could you hold this for a minute? My wrist hurts."

"Oh!" Sakura gasped. Reaching out with her free hand she covered his in her grasp, glowing green energy flowing between them as she soothed the hurt. It still felt strained and she smiled apologetically. "I was telling the truth when I said I can't heal it all right away."

"Feels better," Kakashi said, shrugging. "Now…"

He cleared his throat, surprised to find that he wasn't nervous in the slightest. Probably because he hadn't opened the box and therefore hadn't really asked.

"Can I have that back?"

Sakura frowned.

"Why?"

"Because I'm going to need it later."

"But…"

"I messed up asking you to date me in the first place, I'm not messing up this."

Sakura closed her first around the box protectively. "Uh, it's mine," she said, a touch confused.

Kakashi raised an eyebrow. "Is it?"

"Yes," she nodded, sounding more confident. "I don't think you get do-overs."

"Depends," he said, deceptively light, "on your answer, I'd say."

"Depends," Sakura fired back, "on what you were planning for later."

She didn't sound particularly annoyed, or serious, but he still felt cautious about keeping her happy after her embarrassment. Detailing the circumstances of how he'd planned to propose later, Kakashi watched as his girlfriend nodded along as he described flowers, somewhere nice to eat, a walk to the Hokage mountain, maybe the possibility of incredible sex at the end of the evening.

"Alright," Sakura allowed. "That all sounds suitably romantic."

"I'm glad," he replied. "So can I…"

Gesturing towards where she still clutched the box, Kakashi waited expectantly.

"Nope, this is mine now," Sakura grinned, looking mischievous. "Don't you have a question to ask me?"

"Sakura…" he reserved that tone of voice for when she was being particularly difficult and she recognised it with a widening grin. "Shouldn't we have a nice romantic evening first? Express our love and such?"

"Oh, I think we were doing pretty okay at expressing our love before you panicked."

He levelled a glare at her which she ignored.

"Sakura," Kakashi repeated. "In that case," and he plucked the box from her unresisting grasp, "in that case, will you please be my wife?"

Opening the box with a simple flourish, the Hokage watched as the pink-haired kunoichi leaned forward in his arms, green eyes glittering with excitement as she examined the ring in the box. It was kunoichi-proof (he'd bowed down and asked Ino's sage advice), soft white gold with diamonds inlaid around the band so they wouldn't catch while she was working.

"It's lovely, Kakashi," she breathed, tease gone as she spoke softly. "And of course."

He watched as she slid the band onto her finger. He also watched as her smile turned not-so-innocent again and she wriggled slightly in his lap.

"I felt that," she said with a look that sent his blood flowing south.

"It was a beautiful moment."

"Can we still go on a date later?"

"Of course."

Kakashi sighed as she wrapped pale arms around his neck. It wasn't the way he'd planned it, spending hours agonising over which restaurant was nice without being suspiciously so and which route up to the Hokage mountain would be romantic without being patrolled, but then their relationship hadn't started conventionally. It seemed oddly fitting that it didn't evolve conventionally too, though he was probably going to tell people he'd proposed before dinner or something suitably public.

As though she'd read his mind, Sakura pressed a kiss to the corner of his mouth and leaned back, arms hooked behind his neck.

"You should've just let me find it," she said teasingly as he shook his head disapprovingly. "That'd be one for the gossipers, wouldn't it?"

He growled warningly, hands moving to clasp her waist and shift her petite form so she was straddling him in the chair. But Sakura was never particularly obedient.

"I can see the headline," she continued. "Hokage proposes to Head Medic while her lips are wrapped around his-"

Before she could finish, Kakashi pushed himself up and kissed her soundly, swallowing her words with the kind of kiss he caught her sighing about when she thought he wasn't listening.

And when Sakura didn't protest but melted in his arms, Kakashi smiled against her lips, pushed her backwards onto his desk, and set about bringing the rest of his fantasy into glorious reality.
