A/N: I hope the lemon wasn't too bad. I always think I'm better than I am at writing them. Let me know!

The next day passed as it always had. If Seifer had been expecting Quistis to blush every time they made eye contact, then he was disappointed. She treated him as coolly as anyone else in the class, cutting through his arrogance with acidic remarks and putting him back into second place after Squall. When she was handing back tests they'd done the week before, he couldn't hold back a retort as he got his. He knew he'd got all the answers right, but his paper was covered in red pen. "What the fuck is this, Trepe?"

"Good job, Squall, well done." She pushed her glasses up. "I realise your powers of observation aren't particularly great, Seifer, but it's your exam paper."

"I mean why the fuck is it all wrong?"

"Normally, when you put incorrect answers down, that can be a contributing factor. I suggest you study next time."

He scoffed. "Some of us don't need to study to prove our genius, Trepe."

She sat at her desk and lightly scratched her neck, just revealing one collarbone and enough creamy skin to make Seifer groan inwardly. "Well, any time you want to start proving it, do let me know, won't you? I would hate to be unprepared," she remarked. "Now, page thirty-four, you'll find a list…" Seifer knew that if his looks could kill, there would be a dead Instructor at the front of the class. That led to thinking about the last time he'd seen her lying down. Underneath him, her nubile body writhing in pleasure under his hands. He shifted uncomfortably, then realised exactly why and where he was uncomfortable. Fuck. How can she do that to me without touching me? He was impervious to women for Hyne's sake. He used them once and lost interest after that. Yet here he was more aroused now than he had been last night. He spent the rest of the lesson with his eyes closed, picturing very unsexy things. Cid naked, Cid naked, Cid naked…Urgh that's disgusting. Working though.

When Quistis dismissed the class, he was back to being unruffled again. "Seifer, stay a moment," she said. I knew it wouldn't take her long, he smirked. It never does.

"You after second-helpings, Instructor?" he asked, swaggering to the desk. "I know how hard it can be to-"

"I'm giving you a week's detention," she said crisply without looking up from tidying her desk.

"What?! What the fuck for?"

She stood up, fixing him in her ice-blue gaze. "First, for being late. Then for swearing repeatedly in my class, and for not addressing me in the appropriate fashion."

He raised his eyebrows. "You didn't seem to mind so much last night."

"Twenty hundred hours in the Training Centre tomorrow. I'm sure you can use your genius to figure out where that is," she said coolly. Then she walked away without a backward glance.

"That…bitch! She's a complete bitch! And I wasted my time doing her a favour by screwing her! See if that fucking happens again," he muttered. Then realised he was speaking to an empty classroom. "You're losing it, Almasy," he said darkly to himself. Then, with a growl of frustration, he did the only thing he could do; knocked over the pot of pencils sat on her desk in an extremely childish act of revenge. "See how the ever-organised Quisty likes that," he smirked. Then he stopped. Quisty? Where did that come from… He felt something nagging at the edge of his mind, but pushed it away, stalking from the room to the cafeteria.

He flopped into a chair opposite Raijin and Fujin with his tray of food, proceeding to just pick at it. His posse looked at each other, alarmed by this sudden lack of an appetite. Seifer had never not eaten. Ever. "Uh, you sick, man?" Raijin asked.

"No…"

More alarm. "SURE?"

"I'm not sick, for fuck's sake," Seifer snapped.

Silence. So, uh, you done that assignment yet? Cos if you don't give it to Instructor Trepe soon, she's gonna have your head."

Having heard 'Instructor Trepe', 'give' and 'head' in the same sentence, Seifer's head snapped up so fast it was a wonder his head didn't snap. "What?!"

Even Fujin blinked at the force in his voice. "ESSAY. TOMORROW," she reminded him.

"Oh, right, yeah…." Another paused while it sunk into his brain. "Shit, I've still got to do that." He grabbed an apple from the tray and got up, walking toward the library. He paused at the entrance, realising just how much he hated the library. Heaving a sigh, he decided that at least it would help him get a certain Instructor out of his head. Ten minutes later, he had all the relevant books, and was still thinking about porcelain skin and silky golden hair and lust-hazed sapphire eyes.

A couple of whispering cadets rushed past him, hurrying over to someone. He was tempted to chuck them into detention for disturbing the quiet. He could be concentrating, dammit. Then he started listening to what they were saying. "Shhh! She's over there!"

A giggle, then a soft gasp. "Oh, she's so amazing. She looks so smart!"

His stomach flipped. That was the unmistakable tone of a Trepie. That meant that she couldn't be far away.

Looking up from the pages, he spotted a flash of blonde over by the weapons section. He slammed the book shut, determined that he'd finish this right now. Find out why the hell she thought she could give him detention. He was the head of the Disciplinary Committee for Hyne's sake. He stormed over to her, causing several Trepies to squeak with fright and exit the library rather rapidly, and plucked the book from her hands.

She looked up calmly. "Can I help you with something?"

"What the hell, Quistis?" he demanded.

"This is a library, Seifer, try to keep your voice down."

"You gave me detention," he growled, more quietly despite himself.

"You were late," she replied smoothly.

"You only did it because you wanted me alone and we're sleeping together!"

"Are we? I seem to remember we slept together. There was no talk of repeating it," she said, surveying him coolly from behind her glasses. "Is that all you wanted to say?"

"No!" Then he couldn't think of any way to say that he wanted to do it again without making himself look bad.

Quistis was still waiting for his reply. She arched an eyebrow at his death-glare, then walked away. "You can help me carry these back to my room, I need them for tomorrow's class." She scooped up half a dozen books and walked from the library.

Seifer spent about a minute muttering and thinking up unpleasant was he could kill her, then followed. When he got to the room, he found Quistis sitting on her desk, in the pose that she knew drove him crazy. She smiled at his dumbstruck expression, then slowly reached up and let her hair tumble down from tight style she normally kept it in. His legs strode to her without his consent. She stood up just as they met, bodies rubbing together as their mouths met. There was a small crash as all her belongings fell to the floor as Seifer cleared her desk.

"Hyne we're not…" She gasped as several of her blouse buttons got ripped open and he massaged her breasts. "I suppose….we are…" Suddenly she stopped, pushed Seifer off and running to the door.

"Wha-" he panted. His question was answered when she shut the door. "Oh." He grinned. "I thought for a second-"

She smirked and walked to him, unzipping his vest and throwing it to the floor. "Did you really think I wouldn't want another taste?"

He grinned and pulled her to him as her hands ran greedily over her torso. The next few hours were spent in a haze of lust and hard, urgent movements on her desk, up against the walls, on almost every workstation, on the floor – pretty much everywhere they could think of. By the time Seifer's watch beeped 1 am, Quistis was pressed between Seifer and the wall, arms held above her head and her whole body trembling, coming down from her umpteenth orgasm of the evening. Seifer wasn't in a much better state, sweat beading all over his muscular chest and arms, small wounds from Quistis's nails and teeth on his shoulders and neck. Her long legs were wrapped around his hips while his arms held her waist. His head lay in the hollow of her neck, rising and falling with her panting breath.

"Oh holy Hyne," she breathed finally.

He chuckled. "Seifer will do."

She rolled her eyes, but didn't say anything; the blissful smile remaining on her face. "We should go…"

He nodded finally, kissing her firmly. "Alright."

They dressed quickly facing away from each other, somehow embarrassed despite fucking each other for hours. "Well, um…night, then, I guess," he said finally.

She gave a plastic smile. "Goodnight, Seifer."

He shook his head and walked out of the room. Quistis sighed, denying that the corners of her mouth were turning down because Seifer was gone. He was just a way to get laid, that's all. Didn't mean anything to her. Right?

She stayed sitting on the edge of her desk, biting her lip. She looked up again as the door opened, and Seifer came back in. He strode to her, putting one hand on the back of her neck and wrapping her in a crushing embrace and pressing a hard kiss on her lips. She did smile then; a real, genuine smile that took his breath away. "What was that for?"

He shrugged. "Because you're beautiful. Night, Quis."

She took in another deep breath full of his dizzyingly intoxicating scent, then let go. "Night."

This time, when he'd gone, the smile didn't go away. It stayed on her face until she was lying in bed trying and failing to fall asleep. Her last thought, as slumber finally claimed her, was the look on his face when he told her she was beautiful.

A/N: No real lemon here, but they're tiring to write, somehow. So there you go, I cheated. But hopefully you liked it anyway XD
