Okay so this is entirely random, as I started it waaaay back when I first did the 'Natsume-sensei' chapters and lost all interest in it. Interest that was recently revived. So this is what y'all get; Natsume-sense part 3. Rated SO M THAT IF YOU AREN'T PREPARED FOR IT (and by god by now you really should be) then AVERT YOUR POOR EYES!

This is also about 70 percent my own personal fantasy, yes, there, I said it O.o

Natsume sat at his desk in the staff room, flipping through the last intake of end of year tests and sipping tepid coffee. The results weren't looking good this year.

Compensate me, he'd told her, so he probably shouldn't have sounded so shocked when she knelt down in front of him and grabbed his crotch. He'd sort of wheezed and groaned at the same time, and she flat-out laughed at him.

She was always such a fucking tease.

Blinking heavily, Natsume bolted away from those thoughts and stared even harder at the English paper. 'Don't remember' he told himself, 'not now.'

"Happy birthday, sensei," she'd said, and moved her hand up and grabbed hold of the zip of his fly, and slowly pulled it down as she slipped her other hand inside his trousers, squeezing his hardening erection through the material of his boxers.

"You…can't call me that…" he groaned as she deftly pulled his cock free from his pants and pursed her lips to blow on the head.

Tease, a fucking tease…

"Arg!" he hissed out loud, "stop it!" Narumi turned around and gave him a strange look, as did Jino…as if the staff weren't suspicious of him already.

He shook his head in frustration and focused on the papers: he needed to forget what happened, because if he thought about it now he'd have to stay at this desk for however long it'd take for his hard-on to go away. He needed to stop thinking about that afternoon…

That amazing afternoon…

"Call you what, seeeennsei?" she purred as Natsume had to strongly advise himself not to just come in his boxers right now simply listening to her come up with this shit.

He gasped irregularly and his hips jerked as she placed a fingertip under his head and lifted his erection up slightly; managing to find the most sensitive spot on his cock to do so with – he had yet to work out how she knew this filth, and where in her immature teenaged life had she learnt these kind of things.

"Urg, you… kno-ow what," he paused for a second as he considered whether he should use her name. Then considering the look she was giving him, like a puppy begging for food at the table, he gave in and stutteringly added "M-M-Mikan." His hips jerked again as she kissed his shaft lightly, and he suddenly wondered who was training who in this situation.

"You said this was a terrible birthday, sensei," she said petulantly as she stroked her fingers idly around the skin around his groin and followed the trail of pubic hair up to his navel, "was it really?"

"Don't be such a fucking tease, Sakura." Natsume snapped suddenly in response, and leaned over to grab her shoulder tightly, "this was an appalling birthday, so if you don't do something about it very quickly it's going to be the worst birthday ever." At first he wondered why Mikan suddenly started grinning as he scolded her, especially as he called her Sakura and was also holding her pretty damn hard, but as she wound her fingers around the base of his erection and tightened them very slightly it struck him.

"Say fuck again, Sensei," she instructed as her lower lip quivered with enjoyment, "I like hearing you swear," she tipped her face down and released a warm and humid breath over his cock, and then parted her lips and let a single bead of saliva drip down, "tell me… you're going to fuck my mouth"

Once again Natsume thought that he could easily come right then, but pleaded with his body to hold out at least until she stopped being such a minx and actually put her mouth where her…

He decided not to finish that proverb.

"Urrrr," he groaned as a second string of her spit reached out across the cool air and caught the tip of his cock, running down it and then being slowly massaged over his skin by her soft and obliging fingertips, "I'm going t-to…" he paused, still unable to let go of the few tatters he had left of his sense of duty.

"Say it…" she breathed as her hand made a first, more suggestive than anything, jolting movement along his length, "Sensei." She simply had to get the harsh reality of their current situation into every sentence; they were teacher and student, this kind of relationship was not only taboo but also practically illegal.

But she just wouldn't stop.

"I'm gonn'a-" he heaved as his self-control shattered and he moved his hand to grab a handful of her hair and push her head down onto his aching erection, "f-fuck you." He gasped again as she rewarded him by pressing a kiss against his head and then slid her lips down to take it into her mouth, and then as he felt her eagerly tonguing him a hot trickle of pre-come leaked out of the tip and onto her tongue.

"Fuuuck," Natsume groaned, "fuck-fucking hell, Mikan," he tightened his hand in her hair and began to push her down harder, forcing her to take more of him into her mouth as he thrust upwards at the same time, and heard her gag a little in surprise.

However that only turned him on even more, and she soon recovered; settling her hands against his thighs as an anchor to move against him as he finally felt her start to suck properly.

"Ohh fu-uck," he panted as she picked up a rhythm and throated more and more of him, and as he hurtled towards orgasm Natsume dared to open his eyes and look down at his young, female, sexy-beyond-belief student Mikan Sakura sucking his cock, and even more, looking like she was enjoying it.

"I can't hold it much longer…" he soon wheezed, and apart from perhaps tightening the hand she was using to pump the rest of his shaft a little, Mikan kept on the same steady pace without the slightest suggestion that she was going to stop, and Natsume stifled a loud groan as his climax hit him and he shot his load into her mouth.

Considering the fact that he definitely didn't see her spitting anywhere afterwards, he had to assume she swallowed his cum too, and now that the intoxicating moment of orgasm had passed Natsume was ready for the horrific waved of self-loathing and shame for what he'd just done to one of his students for fuck's sake.

However… he didn't have time to get very far with that when Mikan stood up and took hold of one of his hands by the wrist, then guided it under her skirt to press against her panties, which he instantly realized were soaking wet and she shuddered simply with the pressure of his skin against damp cotton.

"Natsume-Sensei…" Mikan gasped and ground shamelessly against his hand, "I know it's not my birthday… but…." She looked him in the eye and he could see the lust and desire thick in hers, "please?"

If there was a sound heard in that moment, it was Natsume's last shred of restraint snapping like a dry twig, and as he pulled her onto his lap and crushed his mouth onto hers a stream of obscenities too disgusting and vulgar to repeat hissed between his lips.

"Hyuga-san?" Jino interjected curiously and Natsume jumped roughly a foot out of his skin.

"What?!" Natsume yelped guiltily, "What's up?! Why are you yelling?" No one in the staff room dared point out that it was actually Natsume who was yelling.

"You're…drooling…" Narumi-sensei said worriedly, and then added, "have you been working too much overtime again?" as Natsume went a rather furious shade of red and rubbed a glob of spit from corner of his mouth.

Oh god let that have been spit…

Disgusting? Probably. Did I enjoy it? A disgusting amount. Would I do it again? Probably not, I spent an entire day thinking about thinks I thought I just had to change about this and got home and realized that I couldn't change a single word. This is the ultimanium.

Just so you folks know, I'm going in for NaNoWriMo next month so don't expect any updates even at the back of your mind until December at least. If any of you play Final Fantasy X and ship Aurikku, it's going to be an Aurikku so you totally have to read it when I'm done :D

Reviews for the pure perveted and burn-your-eyes-out-lemony smut? You know you want to (I know I do O.o)

(Also if you don't already go and read my other story Arrythmia, it's serious and has plot and I totally made Natsume cry this one time. GO!)
