[NSFW] Turnabout is Fair Play

	“And that’s why I’m this small, now will you please help me?  I’ll be more than happy to answer any questions you have after I’m back to normal!”  The alicorn shouted, her squeaky voice causing just enough commotion to irritate the human’s eardrums.

	“Listen, sparkle bottom, I’m not that interested in how it happened.  The only reason I asked is so I can avoid stepping in whatever voodoo it is you left lying around.”

	“That’s not how magic works!”

	“You said you were using magic and alchemy,” the human corrected.  That was more than enough experimentation for him in one sentence, let alone a multi colored bubbling mess on the floor.  “Just what was it you were trying to alchemize, anyways?”

	“I wasn’t trying to alchemize anything, I was trying to forge a new spell-”

	“What part of I don’t care didn’t you understand?  You know what?  Hold on, I’ll get a broom and you can just hop on that,” he said dismissively, leaving the soaking pony to fall over into the puddle again.

	“Of all the visitors to Equestria, and all the places,” she groaned, the spell still tingling on her wings..

	Eventually the human returned, offering the knobbed wooden handle to the tiny pony.  With a squeak and a rather wet flopping sound, Twilight eventually anchored herself to the broom handle.  The human was quick to move the handle over to a dry countertop, quickly depositing the still dripping mare.

	“Thank you,” the mildly dizzy princess said, shaking her head.  The thick goop clinging to her wings seemed to be unfazed by the sudden movements - still clinging to her plumage.  “This is going to take hours to wash out,” she pouted, holding her wings up to inspect them.

	“Can’t you just use magic and get it out?” the human offered.  As annoying as the pony was, she was still his only connection to a decent time sink of books.

	“If you would’ve read the list of books I’d picked out for you, you’d know that’s-”

	“Not how magic works, right.  I’m not reading some three thousand page textbook for fun; your history books are more interesting than that.”

	“And I would love to lecture you on-”

	“We’ll discuss my interest threshold in you talking later, okay?  Just tell me what I need to do to get you back to normal.”

	“Fine.  You can start by helping me get this gunk off of my wings,” she offered, wings still extended as she glared up at the human.

	“Whatever,” the human shrugged, reaching down to grip one of her wings.  Despite a yelp and some squirming, he did manage to get a finger on either side of said appendages.  Squeezing firmly, he scraped the goo off until it clung like putty to his finger and thumb.
“Just what is it this does?” he asked, pulling his fingers apart to watch the goo coalesce onto his thumb.  Before the princess could answer, the substance on both the human’s hand and her body bubbled and fizzed away.  “Twilight,” the human said plainly, tingling already starting in his hand.

	“Um,” the mare said, her own body starting to tingle.  “Oops?”

	“What do you mean ‘oops?’ This is no time for ‘oops!’”

	“Well, I had to start somewhere, so I decided to use another spell as a basis,” she confessed, withdrawing as the effects spread further along her body.  “Want it, need it, specifically,” she cringed, watching the human react to the effects now.  Struggling to focus now, the human’s addled brain picked the “Want it, need it” phrase from her string of sounds and focused on that.

	“Why in the world would you mix magic like that with alchemy?” the human inquired, sitting down to try and focus.  “What exactly is it going to do to me?”

	“I-I don’t know,” the princess confessed, her brain now just as clouded.  “Whatever it was, it needed two participants,” she groaned, a rather pleasurable tingling now assaulting her nether regions.  “N-no,” she panted, figuring out just what the concoction was working on now.  “Why’d it have to be you?”

	“I-it’s not my fault you’re d-drunk on your own magic!” the human contended, his own lower bits getting far more active than he wanted to admit.  “Why did wh-whatever it is wait for me, anyways?”

	“I don’t know,” the pony responded, her speech flowing more like a rich molasses than the river of words it usually was.  “But I do know h-how to fix it,” she said, immediately clapping her hooves to her mouth.  How could she even think of something like that?  At a time like this!

	“I’m n-not into bestiality,” the human retaliated, rather upset at just how aroused he was becoming.  Finding somewhere to bury his meat should be the last thing on his mind right now, yet here he was, picturing his hands on her soft, supple rear…

	“N-neither am I,” she responded, walking closer to the human’s knees.  “But nopony has to know,” she rationalized, now eyeing the human’s oddly shaped pants.  “We need this,” she insisted, making a quick glide over to his knee.

	The human was panting furiously now, trying anything he could think of to get Twilight out of his head.  His grandma’s baseball card collection turned into lewd poses of the princess.  Chained to a chair, forced to listen to Twilight lecture about magic turned into some kind of brazzers ad.  Listening to her talk turned into a soft gulping sound…

	Unable to resist her own spell concoction, the tiny pony made her way up to the human’s lap.  Using what little magic she could focus, she made short work of the now straining button and accompanying zipper.  The human, still lost in the cloud of artificial lust, was more focused on trying to get her out of his mind than out of his pants.
	Slipping into his boxers, the pony soon found her prize.  Straddling the large, pulsing appendage, she lost her resolve completely.  Laying down completely on his member, she began rubbing her entire body against the massive organ.  Her mind found one goal and set her to it - she wanted to taste his nectar.
	Now fully aware of the tiny pony’s presence in his pants, the human was quick to shed his already loosened pants.  Making short work of his boxers, he found Twilight scooting up towards the tip.  His own resolve buckled to lust as the tiny pony began licking and kissing his extremity.
	Each lick tickled in just the right way.  The desperation of the licking, combined with the intensity of her hold on his manhood, was too much for any remaining defense.  Laying back, he let her have her way, eager now to reach release.  As the heavy cream began to ooze from his member, the pony was quick to lick and slurp it up.
	As soon as the taste overloaded her mouth, all other thoughts fell to the side.  She wanted more of this delicious concoction - to feel it fill her body.  With no argument from the human, she continued her assault.  Kissing the tip of his member wasn’t enough now; instead she took to tonguing his slit, trying to find more nectar as fast as she could.
	The tiny invasion was enough for the human to reward the pony.  His body clenched nearly as hard as she was holding onto him.  The sudden rush of seed filled Twilight’s mouth near instantly, continuing on to launch her small form onto the counter again.  When she landed with a wet plop, the human paid no mind and continued to orgasm.
	Twilight was in heaven.  Rolling in what felt like an ocean of delicious nectar, she continued to drink and slurp as much of it as she could.  The more she drank though, the less there seemed to be.  Knowing fully well that she hadn’t been able to drink that much in such a short amount of time, her brain allowed her to focus on the interesting circumstance.
	The ocean turned pool of nectar was no longer being fed by the human’s pleasures.  Licking up a mouthful of the goo, Twilight savored the taste as she observed a difference in the human’s appearance.  Was he… shorter?
	Having finished devouring the seed on the counter, she leapt back over to the human, straddling his member once more.  It definitely felt like she was touching more of it now - not that she was about to complain.  In fact, she formulated an entirely scientific theory, stomach now feeling significantly emptier than it was when she’d cleaned the table.
	Repeating her assault on his nethers, she was once again rewarded with an impressive amount of seed.  This time though, the extra nectar didn’t shoot her back to the counter.  It felt much smaller than it was previously, despite how long it was taking her to clean from her feathers.  Seeing that the human was now definitely shorter than before, Twilight realized that each orgasm appeared to be affecting both their sizes.
	The idea of the human being small was interesting, but it was more than mere interest that was tickling her nethers.  If she could keep him orgasming, she could keep him shrinking.  She would normally not even consider an experiment like this on a live subject, let alone an endangered one; but a buried fantasy was blending quite nicely with her own fog of lust.
	A micro orgasm at the mere thought of being able to play out one of her fantasies was enough to cause yet another equivalent exchange.  Feeling the small mare’s orgasm dribble down onto his shaft was just what the human needed to achieve his own orgasm.  Instead of tiring, the human was feeling oddly invigorated with each peak.  If this pony wanted his seed so badly, he wasn’t about to hold back.
	Guessing that she was big enough now, the pony aligned herself with the human’s member and planted it as deep as she could get it.  While a mere inch was all that actually penetrated her folds, the incredible stretching was the stuff of legends.  The tightness was doing wonders for the human as well.  Placing one hand around Twilight’s middle, he held her in place and began to climax.
	Just as Twilight’s bank neared its deposit limit, another exchange occurred.  Having once again been robbed of a belly full of warmth, she groaned with a mixture of frustration and arousal as all of the human’s member slipped into her.  Guessing they were roughly the same size, she seized the opportunity and viciously clamped down on his member in its entirety.
	“I want it all,” she growled, looking over her shoulder to the human.  He didn’t respond verbally - both hands now on her flanks to help her achieve her goal.  This time though, the singular orgasm wasn’t enough to fill her like before.  She spun around, still hilted to the human, placing her hooves on his chest.  “All of it,”  she repeated, laying down plant a wet kiss on his alien lips.
	The still artificially enhanced human was eager to oblige, but was finding the mare heavier and heavier after each peak.  When she still wasn’t satisfied, he finally laid down on the chair and took a break.  Now that both of them weren’t getting mutual arousal, the exertion was finally starting to catch up with him.
	Frustrated with the lingering lack of warmth, the pony stood up.  Very nearly at her normal height, she turned to look at the tired human.  Seeing the smattering of nectar on his crotch, she couldn’t help herself and leaned down.  Placing her lips on either side of his legs, she sucked the human into her mouth up to his middle.  Finding the taste she desired, she began treating him less like a partner and more like a toy.
	Again, not that he minded.  While tired, he was nowhere near the point of exhaustion that he couldn’t enjoy pleasure like this.  Her thick, soft tongue pressed him hard against the roof of her mouth.  Each wiggle of her muscle against him urged yet another orgasm on, and a tighter grip of her mouth around his body.
	Far too quickly for Twilight’s pleasure though, he was too small.  At his size, it was now taking multiple orgasms to build up a decent amount to swallow.  Instead, she opened her mouth and let him slide out onto the counter.  Before he could respond or thank her though, her rear descended upon him.  Her glistening slit was the last thing he saw before a warm, wet darkness enveloped his being.
Feeling the human slip completely into her nethers was a bit of a jolt.  While his frantic, tiny movements were electrifying, the intoxicating spell seemed to finally be wearing off.  As the human slid deeper and deeper into her body, the realization of what could happen hit rather hard.  Thanking the stars above that his shrinking seemed to be slowing, Twilight frantically raced to her bedroom to search for a new tool.
	Tumbling about in the princess’s depths, the human was also being pulled from his lust driven haze.  Still disoriented from all the commotion, he started to poke and prod the walls of his fleshy prison for an opening.  Eventually he did come across what he assumed was the tunnel that led him here, he started to press onwards.  This may not have been the most well thought out plan…
With his movements, Twilight’s knees were buckling before she’d even inserted her specifically shaped aid.  Cursing her fantasy, she placed the toy down on the ground and sat on it.  The penetration was swift and fulfilling, but she was doing her best to avoid an orgasm.  If she let herself get carried away again, she might not find the human.

---

	“Science?” the human repeated, wiping more of Twilight’s juices from his arms.  “That’s your excuse?”

	“If I remember right, you enjoyed it just as much as I did!”

	“We were both drugged up on whatever spell that was you conjured up!  Is that stupid spell done for now?”

	“Most of the effects are,” Twilight said, blushing.  Her mouth still watered at the thought of his nectar.  “But the major size changes should dissipate in a week or two.”

	“Great.  I have to worry about shrinking every time you get yourself worked up.”

	“The same goes for me,” the pony implored, licking her lips.  Panting, she looked away from his gaze before continuing.  “Was it all really that bad?” she muttered.

	“No, it wasn’t,” the human finally answered.  As much as he hated to admit it, not all of his pleasure was because of the spell.  “In fact, I probably wouldn’t mind doing something similar again some time.  But that’s the key here - time.  I was just coming to terms with never seeing another human again.”

	“Well, if you ever need to pleasure yourself, you’ll need to be near me.  That way, if we start shrinking again, we don’t lose each other.”

	“I guess that’s not so bad,” the human shrugged.  Maybe he could convince her to give head again.  In fact, maybe he wasn’t as opposed to the princess of friendship being more than just a friend.  Only time would tell though.  “Besides, not all of the effects need to be nullified right away.”
