Yes, sex will now commence.

Her tongue explores your mouth, and you're **** to question... Just why did you wait so long for this? Why hadn't you spent every day making out? You'd wasted so much time dithering about finding the right guy!

It hadn't been your first kiss, really, or even your tenth. But all of the others had been tepid little things, hidden behind excuses and cursed with half-hearted hesitation. This, this was your first real kiss, the one that you'd judge all your other kisses by.

And you knew, you absolutely knew that every other kiss would fall short.

Her tongue playfully wrapped around your own as she sighed into your arms, tasting faintly sweet and laced with something... Exotic. A pleasant tingling filled first your mouth, and then your entire head, as you tried to pull her closer. You knew, of course; this wasn't "just" a good kiss. This was the power of a succubus, to fill you with unearthly pleasure. That tingling was probably the supernatural equivalent of a dangerous narcotic, something that would definitely get you addicted to her.

You knew. You just didn't care.

You pause for a breathe, and the demoness gives you a sultry look in return.

"Still feeling straight, my pretty little student?" She asked.

You look at this ravishing creature before you, and realize... You don't, not in the least. Ha. All of that nonsense about how Taylor would fall for her in a heartbeat, and you were just as ****? Of course you were. You'd seen the other students earlier, right? What had been the odds that none of them were straight?

But now, you could properly enjoy her. A thrill runs through your body as you reach out towards one of her perfect breasts, while you allow her lips to meet yours again. Her breasts were... So very soft, and so eminently squeezable. You let your fingers sink gently into her skin, guessing from your own explorations how far you should go; she gives an appreciative moan into your mouth in return, her kiss deepening.

But while your right hand is occupied, your left hand is left wandering; first, the smooth, soft skin of her side, and then her back. A shot of jealously ran straight through you at how perfect this woman was; she was in her 40s, but her skin was still something you'd kill to have.

...Except, it wouldn't cost you a life if you really wanted it. Just to trade away your soul to her.

You chase the bad thoughts away by letting your hand wander down to her perfect, pert little backside, giving it an appreciative squeeze. You'd always been a bit frustrated by how guys had all of these expectations as to how your butt should look, but now... You understood, you really understood. Yes, it was a pain to keep this thing looking right, but as you gave a little squeeze and pulled her to you... It was worth the work.

Ms. Devlin broke off the kiss, and guided you towards her desk. A vapid thought entered your head for a moment, that this desk had seen the fluids of dozens of students this week, and that yours were about to join them... But you didn't really care. The only scent that filled this room now was Devlin's, and you were happy to surrender yourself to it.

"My, you've really loosened up, haven't you?" Ms. Devlin said, "Just a little kiss, and you were ready to jump all over me, too. Not a hint of self-hatred either, guess you really weren't homophobic. Sorry about saying that, then. Buuut..."

Her hands begin to roam over you in return, exploring your underdeveloped little mounds, running over your coarse and blemished skin. You suppress the urge to hide your shame and cry; you were nothing compared to her, but you'd seen your classmates. She'd been with far worse than you, and you weren't going to pretend otherwise... Even if you cursed yourself for all of your flaws.

"This was meant for me to teach you how to please me," Ms. Devlin teased, "While this body is perfect and fuckable in every way, technique still matters. Your wandering hands are far better than your pathetic excuse for a tongue, but I still don't have the patience to wait around while you improve. Consider this your first lesson."

You're about to joke about how you'd been in her class since the start of the semester when your words are cut short by a gasp of pleasure - your own. Her roaming hands had built up a steady rhythm of pleasure as they'd rubbed around your breasts, and a gentle pinch of her fingers on your nipples had caused that pleasure to reach their peak; your breasts hungered for more as you gasped with arousal, demanding that her fingers sink into you deeply and roughly.

You had never really focused on your own breasts that much; porn had always made it seem so exaggerated and fake, and you'd never experienced a fraction as much pleasure as the actresses pretended to have. Eventually, you'd just written it off as a fetish for guys. But now...

Now you understood. You'd just been doing it wrong for years! In the videos, they just went to town, but that wasn't how it was supposed to be at all! You had to start off gentle, and build up to the rough stuff, and then the rough stuff felt so much fucking better than it ever had before!

...Well, you were pretty sure the actresses were still overacting, but you were still more turned on than you'd ever felt before. This was definitely something you were going to do again, no more skipping the fun part.

But as you were focused on your own personal revelation, Ms. Devlin hadn't been idle. One hand was still playing with your newly needy breasts, but the other was tracing down your pudgy little stomach down to your freshly soaked pussy, tracing gentle circles around your aching clitoris.

"Tell me, my pretty little student..." She whispered into your ear, "When you masturbate, you don't just rely on a lot of crude thrusting, do you?"

You blush at her question, but you've read Cosmo; while some of their tips seem a bit out there, you know that communication in the bedroom is important. The sex demon doubtless knows what she's doing, but she needs to know that _you _know what you're doing.

"More..." You stammer out, "More like gentle thrusting. And pressing on my clit at the end."

Or so you thought, at least? You had largely fast-forwarded through solo scenes in porn, but those girls had seemed to really go at it. You're pretty sure you'd have actually injured yourself if you'd tried that.

The first few times she'd tried hadn't gotten her anywhere, and she'd been left disappointed and confused... But, well, then she'd learned what a clitoris was, and she'd started to enjoy herself a whole lot more.

"Darkness..." Ms. Devlin quietly cursed, "I'm really starting from square one with you, aren't I? You're lucky you're cute."

Your body ached with need, as Ms. Devlin's fingers ran gently across your folds, fingers only dipping slightly inside you; instinctively, your hips buck against her hand at the touch, and her fingers dance as they push against your walls.

"Thrusting sucks, my pretty little student," She whispers in your ear, "All your best nerve endings are higher up, and you want to actually stimulate them. Just skimming across them doesn't work, you want to give them something to feel."

You want to say something back to her, something thanking her for teaching you this pleasure or praising her skill, but... All that comes out is a moan of pleasure as you feel the strongest orgasm you'd ever felt in your life.

...Without even touching your clit? You had been positive that you needed that to come...

Her gentle hands slowed their efforts across your body as you breathe deeply, your body burning with the aftershocks of her care... Slowing, but not stopping, focusing on the less sensitive parts of your body, but steadily drawing closer again with each moment. You bite your lip as you realize what she's doing.

"And a good night doesn't end with just one, my pretty little student," She whispers again, "You're not a man, and don't need to settle for the kinds of boring dates they can offer."

Your body still sensitive from her ministrations, she doesn't bother with the sorts of foreplay she had before; she moves straight towards your clitoris, rubbing circles around the base. You feel a pressure building inside of you, a sense of fulfillment that you'd never experienced before...

"And if you want to play with your clit, there are better ways of doing that too," She continues to whisper, "You don't have to play with your folds at all, if that isn't your thing... Though personally, I'd find that a waste."

A moistened finger glides across your exposed flesh, and you respond with a gasp of surprise and pleasure, hips jerking once more. You don't know if this was her technique, or more succubae tricks, but your body felt many times more sensitive than it ever had before.

"See, my pretty little student?" She whispers once more, "Those pornos of yours were complete garbage. If you want to learn to pleasure yourself... You need a real woman to show you what works..."

And with that, Ms. Devlin began to play with your clit in earnest, her fingers playing with you fast and slow, nearly overstimulating before letting you cool down... Until finally, she gave you a gentle pinch between two fingers, and your body answered with the biggest orgasm you'd ever felt. No, fuck that; were the things you felt before even an orgasm, or merely the promise of one? Fuck, you wish you'd met Ms. Devlin years ago, you feel like you'd wasted so much of your life with what now seemed like blind groping...

The strength left your body, and you practically melted onto her desk. An idle part of your mind noticed that it didn't felt nearly as hard as it should - it was practically a large bed. Some kind of demon trick, probably? That seemed wasteful, but fuck, you weren't going to be complaining. And if she was doing this on a regular basis, maybe it was sensible after all. Silly human, not putting sex first, right?

"Tch, still not realizing your full potential, are you?" Ms. Devlin glared at you as she stood, licking her lips, "You don't think we're just going to end things here, do you? So why are you getting so relaxed? You are here. To. Learn. And we have an oral exam yet to go."

You want to protest, you want to object... You've just come harder than you ever had, twice, in a matter of what was probably minutes. Your body really couldn't take more of this, right? Except...

You felt an answering lust of your own, a desire for more pleasure, more fulfillment, more sex. Maybe it was the atmosphere of this place. Maybe there was something in her kiss from before. Or maybe, it was just the fact that you had had the best sex of your life at her hands, and she was promising you more.

Whatever the answer was, you didn't object; instead, you just gave her a timid nod as you spread yourself open for her. And Ms. Devlin? She completely ignored your open posture, and made her way around you to your breasts again instead.

"I told you not to relax, not to be an idiot," She scolded, "Yeah, I could probably get another orgasm out of you if I focused on your pussy over your clit, but you're so worked up that we'd be losing half the lesson plan that way, and most of what you'd learn would probably be demon-specific. Good spirit, though."

Burning with embarrassment, you pull your legs back together again. Thankfully, she can't see your face as her head lowers to your breasts, leaving a trail of kisses around your mounds. Except... You feel your body cooling a bit, as you realize this isn't really working for you.

Impatient, you pull her head towards towards your peaks - and immediately realize what you've done as a flash of anger crosses her face, before she lowers her mouth to your nipple. You feel mortified for a moment, but it doesn't last long as the pleasure you've come to crave fills you once more; a mix of sensations provides an intoxicating balance, between the soft suction of her kisses and the little nibble of her teeth. You're tempted to ask her to bite you harder, but you're afraid that she will - and you don't know if you're more afraid that you'd like it, or that you wouldn't.

The dance of pleasure feels like it lasts a long time, not that you can tell the passage of time anymore - but it does end, as you feel yourself getting sore and overstimulated. Maybe Ms. Devlin can go forever, being a sex demon - but you're limited to a frail and ugly human body. As you wonder whether you should mention anything, she lifts her head.

"Well," She says, "I had been hoping to stretch that out longer to give the rest of you more of a break, but someone got a trifle impatient, didn't she?"

You cringe for a moment at having displeased your teacher, but she waves it off almost immediately.

"No matter, you're human," She says, "And being a human, all your bodies are put together stupidly. Those kisses would have been great for getting me going again, but I guess a certain someone forgot to give you those nerves. Just remember them when it's time for me. Now - spread 'em."

You nod in acknowledgement as you spread your legs once again. You'd do your best to remember, but... All of this was so new to you. You really hoped she didn't expect too much from you; you could probably actually get the basic technique right this time, but you were certain that she was far, far better than you could ever hope to be.

No, wait, that wasn't the attitude Ms. Devlin wanted you to have. Rather, you were certain that it would take a lot of work to get anywhere near where she was.

Your thoughts are once again interrupted by the sensation of something soft and inviting on your inner folds; Ms. Devlin's tongue, tracing along you. You breathe quickens with urgency as your body responds to her touch, and her tongue pierces you, flowing against your walls as it explores your depths.

You remember your crude fumblings from before, and burn with shame as you experience the difference firsthand. She had promised to eat Ms. Devlin out? Fuck, trying to call that "eating out" would be like bringing someone a homemade cress sandwich and calling it "eating out" because you weren't at home.

But all too soon, it comes to an end as she pulls her tongue back, and you give a plaintive cry - before your clitoris feels her touch instead, her tongue playing with your hard little nub as an avalanche of pleasure threatens to crash upon you. But that, too, comes to an end all too quickly as her tongue eases off and returns to your folds.

...You understood. Really, you started to understand. Sex was the best thing ever. No, wait, no, that wasn't the lesson. You understood; there was a balance that needed to be had here. Exploring your sex, that was the holding pattern, keeping her aroused and interested while backing off; playing with your clit, that was how she built things up, how she escalated. Focus too much on the pussy, and she'd eventually get bored and call you a failure; focus too much on the clit, and she'd come too quickly, and get frustrated from ending things too soon. You needed to offer her both. ...Except, she was a sex demon. That probably didn't apply to her at all, since she could probably keep going long after a human could.

No matter. She said technique still mattered, right? Well, you were going to soak up every. Last. Drop. of her technique.

She repeats the pattern a couple of times, playing with your clit in different ways each time, but she doesn't leave you waiting long at all; on the third time, she gently sucks on your clit, and that avalanche crashes down on you for good, your voice filling her office. You had never been a screamer before, you were pretty sure... But after this you were pretty sure you'd never had a real orgasm before.

"Well, then..." Ms. Devlin says, standing up again, "I do believe that concludes the basic lesson plan. Ready for the exam?"

...Honestly, you feel like mush now. Really horny mush. All you want to do is become one with this table until your limbs stop feeling like noodles. Except...

All of this was to teach you how to pleasure her. And she would not appreciate you flaking out on her now, after showing you such generosity. And whether or not she'd changed your opinion of her, she could get you expelled with a few choice words at this point.

Being lazy wasn't really an option at this point, right?
