Clop at the Abyss, and It Clops at You
This is the last time you get groceries by yourself. If bookfucker wants to eat, she needs to help carry the damn things. You notice a column of multicolored smoke rising from the treebrary, and resign yourself to having to get new clothes. Chances are pretty good she tried another egg-cooking spell, and you learned the hard way that the smell just won't come out.
You crest the hill between the market and your home, and adjust your damage estimates. It's hardly a tree anymore, more like a crystal castle on an ugly column. You set your groceries outside the door, figuring that will be the safest place until the spell is reversed. Far too many stairs later, you enter the main room, which is mostly arches and gussied up chairs around a big old table. Puts you in the mind of force-choking skeptical officers.
At the head of the table is a much larger chair, oddly facing away from you. There is only one way this can go. It turns around, revealing the Fount of Spaghetti, only darker and- Is her horn red and fang like? Shit.
"Anon, I have been waiting for your return."
"I know you're hungry, but I left the groceries downstairs. Why do we have a downstairs?"
Irritation flashes across her face, but it is quickly replaced by arrogance and the odd little smirk that she has when you trigger her info dump card.
"All in good time, Anon, we are certain to have plenty of it. I am seeing the world in a new dark, and the possibilities are sumptuous."
Looks like yet another spell rebounded off her overclocked mind. There are a few ways to go about this, but as her "special somepony", you have developed what has become your favorite solution. Oh wait, she's still talking.
"- by my side, as the stars die and the sun gutters out. What say- Anonymous, I can not believe you! Here I am, offering immortality and dominion, and you weren't even listening!"
You walk towards her, holding your hands up placatingly.
"Sorry, I was just so worried about you. You look different, all dark and sexy."
"S-sexy? I mean, of course, I-"
"But I'm glad you are still the Twilight I fell in love with. Now what were you saying about immortality and bondage play?"
You sit down near her, slipping your shoes off under the table, and giving her your best bedroom eyes.
"Dominion," She automatically corrects.
"As I was saying, join me, and gain unimaginable power. We will overthrow the other princesses, and rule in obsidian splendor. All you have to do is swear undying loyalty to me, and I do mean undying."
You extend your foot, tracing her leg under the table. Twilight's eyes widen, and she opens her mouth to say something. You interrupt.
"How about I show you how undying my devotion is?"
Her cheeks burst into dark flames, and she veritably hops off the chair. She seizes you with off-color magic and runs to the bedroom. You hit the mattress, and your clothes fall from your body in shreds. Damn unicorn magic. She spends a long moment taking in the sight.
"You shall make the most pleasing of consorts, Anonymous."
She teleports onto your chest, and you are faced with a winking pussy. Normally this would be a welcome sight, but the mare is hopped up on evil crystals or something, and you need to do something about that. You seize her hips and roll over.
"Ah! What are you doi-"
Once she's under you, you yank her down and align your cock. The bookfucker gives you her best haughty glare. It's better than what she can manage when not evil, but it's still in the range of a cat forced from its favorite perch. She lifts her chin, trying to seem haughty even as her forelegs draw up in front of her chest.
"Devotion means obedience. You have once chance to please me. If you should fail, I shall find myself a better consort."
You brush your hand along her cheek, glad to note that the shadowy fire didn't burn you. You keep going, combing through her mane close to the scalp, and she closes her eyes in contentment. Your hand loosely grips her horn, and her eyes go wide. You lean down and whisper in her ear,
"Thus always to tyrants."
You spear her below as your hand furiously pumps her horn. Twilight starts squirming immediately, bunching up the sheets beneath her hooves, pushing weakly at your chest.
"What do you think-", haah, "-you are doing?"
She pants from your onslaught of pleasure.
"What does it look like I'm doing? I'm fucking the evil out of you."
Her teeth clench, and you feel her first maregasm around your pumping dick, frantically trying to milk you for semen. She always did like being dominated. Her horn is glowing with a wavering green-black aura, kept from discharging by your diligent stimulation. With your spare hand, you stroke her heaving chest, marveling at the effect you have on her.
"W-when I am free, you, oh sweet Celestia, you will regret your, ooooh yes, your presumption!"
"Presumption? Well, excuse me, Princess. This is presumption."
You stop stroking the soft fur of her chest, and slap her ass. She gasps, and actually manages to push you away a little. Unfortunately for her, you accidentally pull on her horn to keep yourself steady. Between that, and your relentless and vigorous pounding, she cums again, and her horn discharges straight up your arm.
You are flung across the room, and collide painfully with the wall. As you crumple to the ground, you hear her concerned voice.
"Anon! What happened? I'm sorry, I'm so, so sorry! I was experimenting with one of the spells from the Crystal Empire, and- Anon?"
At least it sounds like she's back to normal. You slowly stand up, and you just know you will have a terrible bruise. You see Twilight approach you cautiously, no longer dark and sinister. How... disappointing.
"Concern yourself not with my well-being. I am far more resilient than that. No, what you should be worrying about, is how to please your... master."
You blink, and you see the world in green shadows, so easily torn and sewn into more pleasing alignments.
"Anon? I-"
She swallows.
"I know what I must do."
The princess meekly crawls to you, to your satisfaction. Her head rises to your engorged member, like a suckling foal. She licks it, then slips the head into her exquisite mouth. This is proceeding too slowly, if pleasurably. Time to take matters into your own...
Hands.
"YEEEEEEAAAAHHHHHHHH!"
Twilight freezes, startled by your sudden exclamation. You grab her horn in one hand, and a handful of mane in the other. You thrust into her mouth, plowing her tongue to the side and sliding by her molars. Her eyes go wide, and she puts her hooves on your hips, trying to push away. Like you would let that happen.
You shift your dick up onto her tongue, and take up your rhythmic thrusting, only slightly slowed by her resistance. She makes pleasing little gagging sounds as you prod the back of her throat. She looks up at you with eyes full of love and resolute devotion as you slowly grind your dick against the inside of her cheek. It's such a delectable sight. Her hooves no longer press against you, but rather slide up and down your thighs, pawing at you in worshipful repetition. It's too much to bear.
You pull her head to you, thrusting deeper than anytime before. You enter her throat, that last bit of penetration unleashing the floodgates in your cock. You pour your load directly down her esophagus, blinded by your climax. When the last spasms run their course, you pull out. Twilight gasps, and slowly catches her breath. That's funny, she looks the same, but the shadows have retreated from everything else. When she meets your gaze again, the glow in her eyes tells you the tables have turned.
Again. Dammit. Immediately, you are pressed against the wall by her magic. Try as you might, you can't move.
"We have learned our lessens, haven't we? We are not to orgasm into, or maybe onto each... other... or else it switches again."
You know that look in her eye. She's going to experiment.
"Take a note, Spike."
She pauses. No response. She facehoofs.
"He's still at Rarity's, isn't he?"
"Probably. Although, would you even want him taking these kinds of notes?"
She frowns.
"Good point. Would you...?"
You wiggle your fingers.
"Sorta tied up right now, but sure."
"Oh, right."
You float over to a writing desk, and you sigh fondly. Only Twilight would have a full dictation set up in her bedroom.
"Ready?"
You dip the quill in ink.
"Ready."
You hear schlicking noises. You turn to see your evil marefriend pleasuring herself.
"Test one, self-stimulation."
You dutifully write that down, then turn to watch the show. She catches you looking.
"I command you to not look, it may contaminate the results."
You raise your eyebrows at her. She growls, and your head is forcibly turned to stare at the paper.
"Oh yes, that's better. So much more", ah!, " scientifically sound."
Purple Smart continues to make the occasional moan or grunt, always accompanied by the wet sounds of her marehood. You start to get hard again.
"I'm getting close!"
"Shall I write that down?"
You were being sarcastic, but,
"Yes! Write all my words anon! Everything I have said since I started pleasuring myself!"
You dutifully write down, "I'm getting close."
"How many 'oh, oh yeah's was that? Like six?"
Her breath hitches.
"Seven, I think. Uhnnnn, that makes nine of those."
More writing.
"And what about 'Fuck me, Celestia, fuck me like a dirty whorse!', how many of those?"
You can almost feel her blush.
"That was in roleplay, and a different experimental set and you know it."
Good times.
"Oh, and Twilight?"
She breathes heavily for a moment before replying.
"What now?"
"Two words. Scientific. Rigor."
"STUPID SEXY ANON!"
You hear her juices splash onto the floor, and something hits you from behind. You turn to see what it was,
Wait, you can turn? Time to get revenge on the impudent mare who thought she could control... you.
"Anon, you're evil again, aren't you."
You move to stand over her as she lays panting on the floor.
"Eyup."
She stares at you expectantly.
"What are you waiting for? Aren't you going to spank me or something?
"Tempting, but no. At this point, I think a firm handshake and a knowing wink would transfer the power."
You sit down on the bed to think. Not only that, but the shadows you see are much lighter. Twilight hops up onto the bed and sits beside you. So cute.
You stagger, and she jumps away from you, and humps the wall furiously.
What.
It's then that you notice that the shadows are gone from your vision. The building shudders, and your stomach informs you that you are falling. You roll back onto the bed, and hold on tight. When the world stops shaking, you are happy to see the treebrary is back to its good old self. Twilight, on the other hand, is glaring at you with black smoke pouring from her mouth, nose, and behind. She's evil, but it's hard to take her seriously.
"Nice smoke signal, cinderfart."
Her lips twitch.
"Don't make me laugh."
Corruption End:
(Warning: Contains dubious consent)
You find yourself once more unable to move, now unable to speak.
"Now to do what I should have done in the first place."
A dull black ball sails across your field of vision from the direction of the underground lab. Whispering fills your ears from every direction, and your eyes stare out into a deep abyss set in the air above you. Smoke pours out, choking you, pressing against your every pore. When it clears, you can see the world in perfect dark clarity once again. Twilight stands on the bed and puts a hoof on your chest.
"Now we can rule together, as I had intended."
...
Better. You summon the innocuous black sphere, and hold it in your hand. Twilight stares at you in confusion.
"What are you doing?"
"That you do not know proves me right."
The sphere disintegrates, and coats your hand in barren night.
"I am now the source. All shall serve me."
You stand up, sending her tumbling to the floor. She glares up at you.
"That was not the deal."
"I am altering the deal. Pray I don't alter it any further."
As you walk out the door, Twilight trots to catch up. Immediately, you find Rarity outside, looking worried.
"Are you two alright? Was there a fire? You aren't burned, are you?"
Then she sees your erection, and delicately turns away.
"Something wrong, Rarity?"
"I see the fire came at an inopportune time. Shall I leave you two alone?"
You step forward.
"Of course not, we'd love for you to join us."
She turns back to you, shocked.
"Surely you jest, I-"
Your patience ran out. You lift her up with ease, and pin her to your chest. She starts flailing immediately, still trying to politely disengage from a threesome. You lower her until your cock just barely prods at her lower lips. She freezes. You are pleased to find that she is already wet. She holds her breath.
"You are now mine."
Rarity moans sensually into your shoulder as you shove your manhood deep inside. Twilight meekly sits before you, alternating between licking your balls and tonguing the fashionista's anus. Your hips rock back and forth, sending waves of pleasure into your captive mare. Still, she protests.
"It's not too late to, ah!"
You shift one of your hands down and slowly insert a finger up her ponut. She tries again.
"This is quite rude of you to-"
You lock lips, plundering her mouth with your tongue. She is reduced to moaning as you drive her to climax. Her hooves rustle through your hair, and her hind legs clamp around your waist. You press her pelvis firmly up against yours for one final thrust, and she keens in ecstacy. She closes around you as you fill her womb with your shadow-tainted semen. You pull your finger out of her ass and gently rub her flank as she is filled with your dark power. When she opens her eyes again, they are much darker blue, and her coat writhes with bands of moving shadow. You set her down, and she bows low.
"I am yours, Darling."
"Good. Shall we see what else this town has to offer?"
It is late. You lie in wait in your tower, for the futile resistance of the princesses and an elder of chaos. You have tapped into something older still. There is great power in love, and you love these many mares so very, very much.
Pure End:
"Don't make me laugh."
You keep a straight face.
"Molecules."
Twilight cums. Even as you get hit with the evil, you can't help but laugh. Twilight scowls at you.
"It made me pretty sensitive. In fact,"
She draws close to you, and murmurs,
"Horse pussy."
You are not ready for the surge of pleasure in your loins. Likewise, Twilight was not prepared for the surge of spunk from your junk. She glares at you, the evil just settling in.
"You came on my face!"
So you did.
"It's kinda hot."
Her vag winks at you. The shadows come to your vision much slower now, and you have a plan. You pounce on her, riding her sweet, sweet marehood. She grinds up against you and moans. Almost immediately, the magic surges into her and she orgasms. You aren't sure if it's the magic, or your own deviance, but you whisper in her ear,
"What did you learn today? Why don't you write a letter to Celestia?"
You pull out and roll her onto her stomach. She groans, but obediently levitates the paper, quill and ink over. She shakily begins writing, and you slap that ass.
"Say it out loud."
Marecum spurts from her pussy, and you know you hit on something good.
"D-dear Princess Celestia,"
"Today I learned that ancient forbidden artifacts are sometimes dangerous, even just to examine. However, as long as you have a special somepony, no evil is too powerful to overcome with rough sex, horn jobs, masturbation, and even more sex.
Your faithful student,
Twilight Sparkle.
P.S.: Anonymous sends his regards, and probably some of his semen."
That's your girl. You raise her plot, and resume your vigorous and world-saving fucking. She writhes on the floor, no longer in control of her body, after so many orgasms. You feel yourself building up, as her vagina very nearly matches the impossible experience of receiving blowjobs from twenty of the finest whores of Babylon at once. You cum inside, her pussy drinking every last drop you have to give. You collapse on top of her, still pleasantly buried in her twitching pussy.
Long moments pass. Finally, Twilight asks,
"Is it gone?"
You sigh, nuzzling her neck.
"I think so. There was a notable decrease in potency after each transfer, and goodness knows we sent it back and forth."
Twilight clenches around your softening cock, then relaxes.
"I love it when you talk technical."
"I know."
The two of you rest for a good while longer.
...
"Want to do this again next week?"
