ORAL FIXATION, PART I

She was looking at him again.

Kakashi had several very influential teachers back when he'd been a student. He could understand the kind of awestruck admiration only a true knowledge-seeker could have for the wizened figure of authority responsible for one's education. Though Kakashi would never have indicated it outwardly, he too had suffered from a certain degree of idol worship regarding his legendary mentor, Minato. Kids are prone to seeing stars in their quest to mold themselves into the adults they want to be.

But he was fairly certain he'd never looked at his professors like that.

She sat in the first row, as always, notebook open and pen in hand. But she never took notes. She usually got top marks so Kakashi supposed he wouldn't be bothered by that particular oddity, if not for her other bad behavior. Her eyes tracked him from the second he stepped into the chilly auditorium (20 minutes after the latest student, naturally). They fixed on his form as he leaned against the podium during the lecture. He could feel the weight of her gaze on his back when he scrawled the occasional lazy note across the board. It never left him until he slouched back out the door after class. Every day, she was the last person to leave.

Kakashi watched her watching him (more covertly than she did, of course). She stared, face both intense and carefully blank at once. It was the tip of her pen between her parted lips that gave her away. She chewed on it absently, sliding it along her lower lip, eyes locked on him. She reached up and tucked an errant strand of pink behind her ear. Kakashi swallowed.

He was not a pervert.

"I'm stuck."

Kakashi didn't have to turn to know who addressed him from the doorway of his office.

"Oh?" he responded without glancing up from his paperwork. He didn't invite her in.

She entered anyway, slinking forward into the chair in front of his desk like a cat who knew it shouldn't be there. Felines were always drawn to people who ignored them most.

"It's my thesis. I think I picked one that's too broad." She stared at him, thumbnail in her mouth.

Kakashi sighed and looked up from his work. "Strange. You've never had that problem before. All your papers have been fine thus far." 'Exemplary' would've been a better word, but he didn't want to flatter her too much.

She flushed anyway. The shade was fetching with her unconventional hair color, but Kakashi didn't notice. Or so he told himself sternly.

"Well, this one is really hard," she mumbled.

Poor choice of words. She blinked innocently at him. Kakashi narrowed his eyes, unsure whether to buy her act. He knew from her essays that she could make words work for her. Silently, he held out his palm. She leaned forward to deposit her outline in his hand, shirt gaping open where she'd (accidentally?) missed a button. Kakashi reminded himself that those were the breasts of a girl who was much too young. He leaned back and skimmed the page, chin in his hand, bored expression on his face. He heard her shift, crossing her legs. He finished and looked up.

"There's nothing wrong with this."

She contrived to look surprised. On a less observant man it might have worked. "Oh?"

"It looks like a promising start to me." He tapped his fingers on the desk, sliding her paper back over to her. 'Why are you really here?' hung off the tip of his tongue, but some questions were better left unasked.

The tension hung in the air, thick as the silence. The clock on the wall ticked to mark the passage of time. She looked like she was gathering her courage to say something. Her lips parted. "Prof —"

"If that's all you needed, I'm afraid I have an appointment I must be getting to."

Green eyes pierced him. "An appointment during office hours?" Too bold. No student should be that nosy.

"I have to stop a robbery in progress."

It was so preposterous that she didn't know what to say. For a second he feared she might argue, but instead she just gathered up her things. She shot him an unreadable look.

"I'll see you Monday," she said, slipping out the door. Kakashi didn't glance at the curve of her backside when she left.

He was not a pervert.

It was raining when he stepped into the pub. He shook out his umbrella and was in the process of shrugging out of his wet coat when he caught a flash of pink sitting at the bar.

Nope.

He managed to get one sleeve back on and was about to hightail it out of the pub when, like a magnet, her head turned towards him.

"Kakashi," she exclaimed in genuine surprise. Damn. Now he couldn't leave without being obvious. Reluctantly, he slunk over to his usual bar stool (two down from the one currently occupied by a certain pink-haired nymphet) and sat. He signaled the bartender for his usual. Green eyes burned a hole in his collar.

"'Professor,'" he corrected as the bartender, Ayame, set a pint of dark beer in front of him. His student blinked.

"What?"

"'Professor Hatake,' please."

She turned crimson. "Sorry, that's just what everyone calls you behind your back." She laughed awkwardly.

"Maybe you do, but that's not what everyone else calls me behind my back," he muttered into his beer. His classes had such a high failure rate that he was none too popular (one persistent rumor suggested he once killed a student for handing in a particularly awful paper). His nicknames included, 'The GPA Assassin,' 'Hardass Hatake,' and especially, 'That Fucker.'

She swallowed. "I bet women call you something else entirely behind your back."

Another question better left unasked. He really didn't want to know. It was time to finish his beer and leave, but Kakashi hated to chug. He was not the hurrying sort. The silence languished between them. He prayed someone would sit down in one of the empty stools separating them.

As though she overheard his thoughts, she picked up her purse (pink like her hair, what was with this girl and her penchant for dressing even younger than she was?) and slid off her stool. Kakashi felt her arm brush against his as she seated herself next to him boldly.

"Can I buy you a beer, Professor?"

He arched an eyebrow at her. "Are you even old enough to drink?"

She scowled. "Would I be in a bar if I wasn't?"

Kakashi shrugged and took another sip. He had certainly spent enough time loitering in bars when he was underage.

"Is that a yes?" she persisted.

"No."

She frowned. "Why not?"

"I fear you'd get me drunk and take advantage of your poor old teacher."

She laughed like it was a joke. "I only take advantage of men who know my name."

Kakashi waited for it, taking another sip.

"Do you know my name, Professor?"

He drained his beer. "Of course. I know all my students' names," he lied.

Her eyebrows shot up. "Is that so?" A smirk tugged at the corner of her mouth. The ice in Kakashi's belly told him he'd misstepped. "Who's the blonde guy with the loud mouth?"

"Naruto." Kakashi signaled for the check.

"Who's the bored one who falls asleep all the time and still gets better marks than me?"

"Sasuke." Here it comes. Kakashi drummed his fingers on the bar top impatiently. Ayame was busy flirting with some chain smoker at the end of the bar. But if he skipped out on the bill again, they would definitely have him arrested. Everybody has their limits.

"Who's the bitchy blonde girl who never, ever stops talking over you?"

"...I have several blonde students," he dodged.

"I mean the bitchy one. Who always sits next to me."

This was news to Kakashi. He hadn't realized this girl sat next to anyone routinely. He didn't want to think about why he'd overlook something like that. Judging from the self-satisfied expression on her face, she was thinking about exactly why he may have overlooked something like that.

"Hinata?" he hedged, knowing he couldn't be so lucky. Where the hell was that check?

Her smirk spread so wide it threatened to consume her face. "Not even close."

"Do you know how many hundreds of students I teach?" he grumbled, trying in vain to catch Ayame's eye. He knew what was coming next.

"What's my name, Professor?"

And there it is. Kakashi sighed in resignation. "Sakura, wasn't it?" He feigned uncertainty.

She didn't buy it. She propped an elbow on the bar, looking like the cat that ate the canary. "Mmm-hmm."

He stood, grabbing his coat. He forced a grin at her. She was taken aback by the unexpected change in his demeanor.

"Well! Thanks so much for buying me that drink, Sakura," he said loudly enough for Ayame to hear.

Her brows knit together. "Wha — ?"

But he was already out the door.

Kakashi had just plopped down to a pleasant lunch outside the library. He had a way of lounging on the bench like he owned it. There was a delicious chicken salad sandwich in one hand, the latest Icha Icha book in the other, and life was good.

Or it was until he smelled cherries.

Recognizing that perfume (why the hell do you recognize that perfume? You're not a pervert!), he groaned inwardly at the sound of the wooden bench creaking beneath another body. He didn't bother to be surprised when he looked up to see Sakura beaming at him.

"Are you following me?" He didn't mince words.

She sucked in her cheek in amusement. "Why would you think that?"

"You have a habit of appearing everywhere I go lately."

"I believe it was you who turned up unexpectedly during my last night out," she pointed out.

"Touche." Kakashi took a bite of his sandwich, chewing slowly. Sakura watched his mouth in an unhealthy way. He put the sandwich down. "Can I help you with something?"

He regretted the words as soon as they were out of his mouth. Sakura's smile took on a devious edge. "I'm sure you could help me with lots of things, Professor."

He ignored the innuendo and stared at her expectantly. Round green eyes met his gaze, nonplussed. They were deadlocked for a good minute. Cursing himself, he caved first.

"Are you going to elaborate or do you plan to stare at me all day?"

She mulled this over carefully. "I have to pick one?"

Kakashi resisted the urge to smack his palm to his forehead. This girl was too much. Really. It wasn't even fair. His expression must have been pretty long-suffering, because she finally took pity on him.

"Actually, I just wanted to return the umbrella you left in the pub," she said, lifting said object from where she'd propped it out of sight against the bench. Kakashi's jaw almost dropped. Almost.

"...you couldn't have given it to me after class or something?"

"Is that the appropriate time to give it to you, Kakashi?"

"...'Professor.'"

"I'm not a professor yet, you can call me Sakura." Her barely contained laughter told him she was enjoying winding him up far too much. To his horror, Kakashi found he was rather enjoying it as well. Worthy opponents at verbal sparring were few and far between.

But she was so young...!

His thoughts were rapidly circling the drain in a dangerous direction (age gap is not that bad, old enough to drink at least, able to hold an intelligent conversation, etc). He was almost grateful when the intrusion of her voice snapped him out of it.

"So that's two, then."

Some questions were better left unasked. But Kakashi couldn't help himself. "Two what?"

"Two favors you owe me."

"How do you figure that?" he asked flatly.

She ticked them off her fingers, painted with chipped green polish that Kakashi hated himself for noticing matched her eyes. "One for the beer, the second for the umbrella."

"You offered to buy me that beer."

"No, I offered to buy you another beer," she shot back. "An offer which you declined."

Kakashi crossed his arms. He did not want to play this game with her, but his usually impressive brain was having difficulty thinking of a way out. He was spared this rare moment of uncertainty when she sprang lightly to her feet.

"I think I'll wait to cash them in on a rainy day. Don't worry, Hatake Kakashi, I won't make you do anything you don't want to do." She offered him a cheeky smile before spinning on her heel and darting away.

"Call me 'Professor!'" he shouted after her retreating figure without any real conviction. His eyes may have skimmed over her white skirt as she went, but it wasn't because he was a pervert.

She just had a really cute ass.

The semester breezed by faster than Kakashi anticipated. Winter break was almost upon them. Sakura continued to watch him like a hawk during class. To his dismay, Kakashi found his traitorous eyes lingering on her more often than he'd like. He began to notice details about her, like the feminine shape of her ears, or how she had a penchant for handmade scarves. They were usually too big for her petite shoulders, and riddled with holes. He wondered if she was a knitter.

He also noticed her skirts getting shorter and shorter. The tight leggings beneath them didn't detract from the effect.

Needless to say, Kakashi had never been so grateful for winter break before. He would have weeks of reprieve from what he'd begun affectionately referring to as his proverbial 'little girl problem.'

Kakashi was disappointed to find that his vacation didn't even last a week.

He was heading back to his apartment (he could afford a house, but with only one person to fill it, why bother?) from the grocery store. He drove through the ice-slicked streets like an old lady — not because of the snow, but because he always drove like an old lady. He was waiting at a stoplight reading Icha Icha when he happened to glance up. Maybe it was chance, maybe it was an inexplicable instinct, but either way, he saw her.

Sitting bundled by the side of the road was a pink mass. Next to her, the hood of a parked car smoked. She had her chin in her hands and was staring at the dirty curb. She didn't notice him.

Nope.

The light turned green and he punched the gas pedal. She'd be fine. Someone else would help her. It wasn't his business.

He didn't make it three blocks before he turned around.

The startled look on her face when he pulled up alongside her and rolled down the window was priceless. "Kakashi!"

"'Professor Kakashi', at least," he reminded her. "Time to cash in one of those favors I owe you?"

Her eyebrows lifted. "You'll give me a ride?"

Against all rationality, he nodded. Something akin to doom settled in his stomach.

"Thank you!" She yanked open his passenger door with such force he was afraid she'd pull it off the hinges. She climbed in, smelling of snow and gasoline. Kakashi was surprised to find he didn't mind the strange combination so much. Her clothes dripped on his seat, but he didn't mind that either.

Kakashi pulled into the parking lot outside a large apartment building. Sakura slammed the door (too hard again) and ran around to the driver's side window.

"Thanks so much for the ride! Would you, um, like to come up for some tea or something? Maybe a bite to eat? I've got Chinese take-out." She smiled.

Chinese take-out happened to be Kakashi's favorite, but he knew a truly terrible idea when he heard one. "I would, but I'm scheduled to free all the animals from the zoo in an hour."

Sakura bit her lip, considered him for a moment. "I think the animals can wait, because I'd like to cash in my second favor. I want you to come upstairs with me and eat something."

Kakashi sighed. This was the point where the rules dictated he should end their little game. He could get into serious trouble following a young female student into her apartment alone. Kakashi drummed his fingers on the steering wheel. Maybe it was his innate distaste for rules, maybe it was his poor judgement, or maybe it was the way she looked at him with such fearless, hopeful eyes. But whatever it was, Kakashi found himself shutting off the engine and stepping out of his car.

"Awesome!" she exclaimed gleefully, grabbing his wrist like they were already that familiar and hauling him up several flights of stairs to her apartment. He didn't even have time to second-guess himself. Much.

She led him to a door labeled 321 in peeling letters. Kakashi briefly wondered if it was a countdown to the impending demise of his willpower, until he reminded himself that they were just having Chinese food. There was nothing remotely sexy about greasy, delicious take-out.

Sakura fumbled the key twice in her eagerness to get it into the lock. Kakashi thought she must be really hungry. Finally she flung the door open and ushered him inside. He felt a bit like a mouse entering a lion's den when she closed it behind them, put the chain on and locked it with an ominous click. Kakashi swallowed, throat dry. He was surprised when she lead him past the tiny kitchen into the living room. Doubly so when she pointed to the armchair.

"Sit," she instructed.

Kakashi sat.

She remained standing in front of him and began unzipping her windbreaker. The bulky jacket left a lot to the imagination, but Kakashi's imagination was very gifted. He cleared his throat.

"So. About that food..."

When Sakura shot him that cat-who-ate-the-canary smirk again, he knew he was in trouble. Kakashi's eyes were glued to her deft fingers as she shed her boots and her gloves. She unwound the scarf from her neck and dropped it to the carpet. Something stirred in Kakashi's belly, but it wasn't hunger.

"For an English professor, you sure do overlook language sometimes." Her sweater fell to the floor, leaving her in only a long-sleeved button down shirt and jeans.

He was beginning to sweat. "What do you mean?"

Sakura toyed with the top button on her shirt. Kakashi was willing to bet she didn't have any more layers on under that. A growing part of him really, really wanted to find out if he was right.

"I believe our agreement was simply that you come up and 'eat something.' I never specified what." She undid the top of her jeans.

Kakashi's jaw gaped. Her words had been deliberate all along. Everything had been deliberate all along. Okay, fine, he was a pervert, but she was a pervert! Was this her plan from the beginning?

"That's cheating," he protested weakly. To his amazement, the thought of being caught in her mousetrap was incredibly appealing. He stared at her zipper as if he could undo it with his eyes. She noticed and grinned.

"Kakashi, it's stuck," she teased, tugging at the tab without even pretending to try. "Could you help me?"

Wordlessly, he stood. He towered over her at his full height, and he liked the way her spine arched when she noticed that. She took a step back as he stepped forward. He marched her until the backs of her knees hit the couch.

"Sit," he instructed.

She sat.

He leaned down until his mouth was inches from hers. Her lips were parted in soft surprise, or anticipation. Her breath was warm and sweet. She was all rosy cheeks and bedroom eyes. The green orbs swallowed him.

"Call me 'Professor,'" he growled. He pushed her back into the couch.
