"They got them out again!" Smooth Talker gestured at the scene of a still house. "You said we'd have a stallion by now!"

"I didn't." In truth, Organized Chaos had indeed hoped one creature would put the plug in and get sucked over to fulfill their duty, but the result had been more interesting. "And this is a much better result. Look, it's spreading in its effects, and has even found one weak-willed enough to be completely trapped."

Smooth, who had looked away from the scrying, glared back at it.

Susan, having woken up in a strange bed completely naked (and once again human), was attempting to persuade herself that this wasn't a walk of shame. But, walking through an up-market house naked, trying to find where her clothes were, really didn't help.

Remembering the night before in bits and pieces, Susan recalled that Steven had put her clothes in the wash before going to bed. That thought helped salve her pride. They may be a bunch of deviants, but they were nice deviants.

Sure enough, when she found the laundry, her boxer shorts, skirt, and shirt were sitting in the washer/drier, but her bra was nowhere to be seen. "Right, the bathroom."

Feeling a little less shameful now she had clothes on, Susan slipped into the bathroom and was struck by the smell of several little stallions' musk. With the olfactory impact, more memories flooded into her head—detailing what she'd gotten into the previous night in glorious morning-after detail. Her bra was sitting on the vanity, but her eyes were drawn to two shapes still in the shower.

The two butt plugs sat, still and waiting, ready to snare the mind and eye of the unwary. Susan took a few steps to the shower and reached in to pick up the one Steven had been using the previous day.

With the toy in her hand, Susan felt like a jolt of pleasure shot through her body aimed right at her butt. She wanted it in. She needed it in. "No. I need to get it home before playing with it." Not stealing the toy didn't even cross Susan's mind—the toy's mind-bending was version of a particular spell from Equestria, often called Want-It-Need-It.

Grabbing her bra, Susan made her way for the front door and slipped out, locking it behind her.

"See! Now that one has a plug, is under its influence, and will be alone when it kicks in. Expect to have a stallion in under twenty-four hours." Feeling particularly proud of herself, Organized Chaos used her magic to flick an imaginary piece of fluff off her shoulder. "And, since you didn't believe me, I think Dazed Dream will get first turn."

"What?!"

"She's been patient and has helped distract the town while this project ramps up. She deserves to be sated first."

"The mayor of our little town slutting herself to any recovered villain who wants to order somepony around is not helping the town. The only reason she got to be mayor is she slept with everypony." Frumping a little, Smooth Talker huffed. "I even ran a story exposing her."

"Yeah, and how far did that get you?"

Smooth Talker narrowed her eyes for a moment, hoping to intimidate Organized Chaos out of her line of questioning. It didn't work. "It just made her more popular."

"Right. You created a laundry list of things our wonderful mayor is into, and the whole town breathed a sigh of relief that they could ask her to do more of them. Dazed is the popular mare, Smooth. There's nothing nerds like us can do excep—"

"You were bucking her, too."

"—except jump on the ride. You should give her a try."

"She's an airhead!"

"She's a fun airhead."

Celeste gave an experimental hump when she woke. No penis. "This is the best thing ever. What time is it?" Reaching around her bed, searching for her phone, she finally picked it up and groaned. "Well, it was just about time to get—"

Her alarm started going off.

Hearing the alarm sounding, Steven slowly rolled out of bed and onto his feet. Two of them. Grinning, he searched his drawer for a pair of clean boxers, a pair of socks, a shirt, and a pair of actually concealing shorts.

Walking through to the kitchen, Steven was glad to see there was very little mess to clean up this time. Then he remembered that most of it would be in the bathroom or on the comforter of Celeste's bed. "Laundry day it is. But first thing's first."

By the time Celeste got out of the shower, there was coffee brewing and she only had to follow her nose to the pot. "You are a hero, you know that?"

The microwave beeped, and Steven reached up to empty it of its pizza slices. "Well, as planned, pizza leftovers. Speaking of which, where is our pizza girl?" He picked one piece up and took a big bite out of it.

"She wasn't in the spare room. I expected her to be out here. Maybe she left early?"

"Maybe. She seemed kinda nervous last night—until she changed, that is. Well, she has our number. She can call if she wants to come over again or ask about what happened."

"Let's wait for her to contact us. Pizza is nice as a once-off, but I don't think I'd like to have it too often." Celeste lifted her dark coffee to her lips and took a long sip. "Oh heck that's the good stuff."

Steven looked down at his own piece of pizza more critically. "Maybe next time I'll make us pizza by hand. Can't be too hard."

"Did you get your plug out of the shower earlier?"

The question made Steven look up at Celeste (never a bad thing) with a growing unease. "What do you mean? I left both of them in there last night before helping you with Susie." He started walking toward the hallway, intent on checking the bathroom. "Check the laundry."

With Steven's tone grown serious, Celeste hurried along in his wake but turned into the laundry. The moment she did, she could see the machine was emptied. "Her clothes are gone!"

"So's my plug." Steven looked at the remaining enchanted toy with a bit of worry.

"She stole it?"

"You remember how much we needed to put those things in, right?" With a sigh, Steven gestured at Celeste's plug. "I can feel that one doing a number on me already. We can't blame her for it."

Celeste perked up. "So I get to stuff a new plug in you tonight?"

"Maybe. If we can find Susie and get—It's not Susie, is it?" Walking over to Celeste's plug, Steven picked it up and felt its force trying to worm into his head. "Can the silliness, butt plug, I'm gonna let you do your thing again."

"And now I have to try to get the image of you talking to my butt plug out of my head before work. Bye, Steven." Celeste walked up to her friend and kissed his cheek before she realized what she was doing.

Surprised at the kiss, Steven gave Celeste a pat on the rump to send her on her way. "If you get a chance to track S—whatever her name was—let me know."

"Will do. Do we need anything for dinner tonight?" Celeste felt like dancing. Her weeks were normally when she didn't get any action, but so far it had been a party every night for her. "Don't get me wrong, that pizza was good, but three meals of it in two days is…"

"Yeah, I know. I've got all the stuff here to make up a few different dishes. Anything in particular you feel like?" Following Celeste down the hallway toward the kitchen, he tried to not think about the plug in his hand. Sensing that his close bond with another plug was lost, the magical device had set about reestablishing its control over his libido.

"That grilled fish you made last month was to die for."

"You'll need to grab me some fish fillets, then. The good news is I can grill those quickly and have the sides ready to go. Don't be late, 'kay?" The toy in his hand felt like it was connecting a leash to his prostate and pulling on it. Resigned to a boner that probably wasn't going to be going away without work, Steven walked up to the sink and set about washing the toy. It was already clean, thanks to the shower, but that was beside the point.

Getting all the breakfast plates cleaned while Celeste left for work, then mopping up and cleaning the house, Steven had to focus on his tasks extra hard. One stray thought and he'd be reaching back to rub his butt—mind drifting to how empty he felt.

When lunch time rolled around, and Steven had finally finished cleaning the house, he settled for a couple of apples and a quick round of masturbation to ease his morning stiffness, then he headed out into the garden to get his normal chores done outside.

Her day had gone rather poorly. Susan had spent nearly five whole minutes staring at the toy when she got home from Celeste and Steven's house before she was reaching for the toy. Her hand held the thing and her eyes feasted upon it. A powerful desire built ever higher, but she had two problems to solve before she could use it.

Placating her soaring libido with one hand between her legs, Susan rubbed the plug along her vulva while she reached for her phone with her other hand.

"Hey, Sam, you don't need me tonight, right?" The word tumbled out of Susan while her hand rubbed the toy between her legs. The pleasure of its movement caused her less stuttering than if she hadn't actually been masturbating.

"Susan? Are you doing okay? You sound a bit out of breath…" Sam wasn't an idiot. His casual employee of a few years—who was never seen with anyone significantly—was taking evenings off and speaking breathless over the phone. There was only one answer in Sam's mind. "Take the week off if you need it."

Almost climaxing in relief, Susan slumped into her chair and slowed down her stroking. "Th-Thanks, Sam. You're the best." She had some money put aside, anyway. A few days to live out her lifelong dream of being a pony stallion was a small price to pay.

"Yeah, yeah. Just don't let him wear you out." Sam hung up the phone before Susan could reply.

Grinding the plug along her vulva the moment the phone registered her boss had hung up, Susan climaxed hard and squirmed in place. The phone call had served both the things she needed it to—her boss wouldn't be calling while she was getting off as a pony, and the toy was now well lubed.

Turning into a pony stallion, of course, hadn't been her lifelong dream. But, it was the dream that the plug was thrusting into the fore of her mind—telling her it was her lifelong dream.

Living alone had its advantages, and being able to masturbate with a toy in the living room was one of the big ones. Looking down at the messy toy, Susan smiled and walked on her wobbly legs to the couch. Getting up on her hands and knees, she reached behind herself and pulled her boxers down at the rear and lined the slick toy up.

The first kiss of her pucker against the tip almost pushed her back into an orgasm. Her motor went from idling down after release to wide-open throttle again. Susan's supporting arm on the couch wobbled and folded under her, which resulted in her shoulders and chest pushed into the couch while her rear was up in the air.

With the toy slick but her anus dry, there was going to be some pushing involved—or at least there should have been. Susan stared ahead with wide, unseeing eyes as the toy spread her sphincter aside like she'd used plenty of lube.

The feel of the plug stretching her drowned out everything. Susan couldn't hear anything but her own moans as the toy reached its widest part. The enchanted toy played a drum in her head that beat with her heart. Each thud crashed around her mind and scattered any thoughts that might impose themselves between her and getting the toy all the way in. It took just one little push—at the top of a beat—for the bulge of the toy to pass her sphincter.

Susan's anal muscles did the rest. Squeezing down on the slope behind the toy, her anus tightened back up behind it on the thin shaft that joined the plug to its base.

A climax overwhelmed Susan completely as the fullness blossomed inside her and began its work of changing her to its needs.

She flopped sideways onto the couch and made soft mewling sounds as the last female orgasm of her day crowded in around her. Pleasure only seemed to grow, however, and while she was squirming her vulva slowly closed over and a heavy sheath and balls dropped down from her lower belly.

Of course, Susan felt this happening. She felt as her body flipped its sex from female to male, and she felt as the thing in her rear urged her on. One hand grabbed at her chest to squeeze a breast while the other sought out her sheath.

Just touching the entrance made Susan squirm even more—rolling onto her back. She looked past her breasts and down at the hefty, blue-colored flesh and started to massage it. Rewarded quickly, her shaft's flared tip pushed out first, followed by inch after inch of prime stallion shaft. Showing all the self-restraint she could, Susan still hadn't actually touched the raw shaft, but as it stopped growing out and started to thicken, she slipped her hand up and closed her fingers around the flare.

Nothing in her life had ever felt as good as her hand wrapped around her shaft. She didn't even have to move her fingers and she could feel her pleasure shooting up toward the dizzying peak of orgasm. Squeezing a little tighter around her penis, Susan moaned aloud and likewise squeezed at her shrinking breast.

Everything was too sensitive. Susan felt the moment—like the ones the previous night—just before a male orgasm. Her nuts tightened and swelled a little, her shaft plumped a little more, and she expected the pure relief of male orgasm to come any moment.

But it didn't. Widening her eyes and struggling in her clothing, Susan's hand started pumping her shaft now, working it from ring to tip. Each motion of her hand up and each motion of her hand down was pure bliss. Her pleasure grew beyond what a simple orgasm would ever give, but at the same time her body ached for that release all the same.

Whining now, her balls swollen and fit to burst, Susan could feel an odd tingle start in her hand—then a cramp.

Fingers merged and twisted, muscles pulled at tendons that no longer existed before they too were gone. Her fingernails merged together into one coherent mass as a hoof formed from what used to be Susan's hand. She stared at the ~~de~~reformed, blue hand in shock while her other reached down to take up its duty.

Getting more turned on by the transformation taking place as her right arm slowly became a right foreleg, Susan nonetheless didn't stop stroking herself until she felt a similar cramp in her other hand.

The sudden ache of not being rubbed made her squirm into a tight ball on the couch and try to wrap her mouth around her large shaft—but for all its size it was just out of reach.

What she did get, as her feet started to cramp up, was a spurt right in the face from her shaft. It wasn't the thick semen she'd expelled the previous night, but a thin pre-ejaculate that drowned her nose in musk.

Her mind filled with images of stallions and mares offering themselves to her. Susan dropped sideways off the couch and angled her body so she could rub her shaft against the cushion. Humping, Susan's mind focused like a laser down to a single point—a single need.

Susan wouldn't stop until she got relief.

Steven sat at the kitchen table, ignoring the desire burning in his groin and rear. He wanted to shove the plug into his rear so much it almost physically hurt—but he was a rock. "You think Susan will come over tonight?"

"With the plug?" Celeste speared another piece of the catfish on her fork, used it to chase some of the sauce Steven had made around a bit, before holding it up to her mouth. "Maybe. What if she's at home humping all the furniture, trying to get off?" She popped the fish in her mouth and sighed happily.

"Then she learns her lesson about stealing my stuff?" Steven asked.

Taking the time to finish her mouthful, Celeste cocked her mouth a little. "I thought you were being nice about it and claiming it was the toy's doing?"

"It was the toy's doing that made her grab it. It was her doing that made her run out the door with it. Look, if she'd stuck around, I would have bitten the bullet and pulled the thing out of her—maybe even gotten my own that way. We can't find her, so there's no point worrying about what we can't help with."

Celeste let the conversation hang while she enjoyed her meal. The fish had been as fresh as she could find, and Steven always knew how to bring out the best in any meal. Her own efforts were amateurish at best compared to him, though he never complained about her cooking.

Not for the first time did Celeste look at Steven with an eye toward taking a relationship all the way. He was smart, responsible, a great lay, honest to a fault, and could cook better than anyone she'd ever met before. That he was also into some of the kinkiest stuff she'd gotten herself into too was a big bonus too.

When she was finally done with the meal, she put her knife and fork together on the plate and looked across the table at Steven. "So we make a new plug tonight?"

"Yeah. If it will do it again. How many times can it split?"

"Given it's kinda magic and all that, maybe forever? Do we want to try making duplicate plugs?" Celeste didn't get up to clear the table quite yet—she wanted an answer first.

"You know what, let's try it. So you put your plug in, we'll see if we can get your plug to make me a new one, then you pull that out and we try again."

"How many times should we try?"

"Let's stop with two spares. I don't want to wind up with a closet full of the things, but I'd also not want to lose all the ones we have. We'll keep one spare around and hide the other so no one can find it." As he spoke, Steven stood up and reached across to collect Celeste's plate.

"You've really thought this through that much?" Celeste passed her plate to Steven.

Taking the plate and walking to the sink, Steven shrugged his shoulders. "Well, this has been wildest time of my life. Of course I'm going to make sure it doesn't screw up."

"There's one thing we forgot, though." Picking up her glass, Celeste took a long sip and tried not to giggle. "You stayed human last time for as long as you could so you could give me a hand job, and I totally said I'd return the favor."

Steven stopped for a moment and looked at Celeste. There was a lot to be said for getting that kind of offer. "I can't say no to that."

Celeste like the hungry look she got from Steven. "Good. Besides, you already got to feel what it was like, I want a turn."

Steven, washing the dishes, felt Celeste move in behind him and grab his hips with her hands while she planted her groin against the middle of his butt. He was happy enough to push back against her, and was happier still to hear her let out a happy little grunt. "You really like having a dick, don't you?"

"Horse dick, and yes. It's a fun little piece of equipment. Don't you like having one?"

When Celeste's right hand traced around his hip to his crotch—and squeezed—Steven made an appreciative grunt and pushed his rump back a little firmer against Celeste. "Yeah. It's way more sensitive than normal, and… Come on, it's a literal horsecock. Who else can say they're literally hung like a horse?"

"Admittedly, it's a small horse, but you're right. Look, I'll finish cleaning up, you go put your new best friend up your butt and then you do your best to catch me with your wiles." Celeste squeezed Steve's crotch again before letting go and stepping up to the sink.

"You want me to hunt you with my magic butt plug? Celeste, when did you get so damn kinky?" Shaking his hands to dry them, Steven stepped out of the way and walked out of the kitchen to the sound of Celeste's laughter.

"About the time I found out boys are cute." Turning her head as she started to scrub the dishes, Celeste watched Steven leave the room and bit her lower lip. She didn't have long to wait. Celeste had just finished scrubbing the plates and dried them when she heard hooves on hardwood. Turning her head, she saw Steven looking back at her with a smirk on his little pony face. "Oh no! One of those monster ponies!"

"Yes! It's me, and I've come to remake you into a pony too—once I've made good use of that hand of yours." Slow, careful steps took Steven forward. He held Celeste's eyes with his own.

"Wait, you're color changed to—Oh! Your coat, mane, and tail colors are related to the color of the toy that turned you!" The revelation distracted Celeste as Steven quickly turned around and lifted his tail. All her thoughts of role-play and games sloughed away at the site of the plug nestled in Steven's rear.

Looking back over his shoulder as he waved his ass at Celeste, Steven could see he had her. Her eyes literally moved to keep focused on his ass like it was the pendulum-watch of some bizarre hypnosis porn. "Why don't you come over and have a closer look at it?"

The suggestion made way too much sense to Celeste in her mesmerized state. She nodded vacantly, her hand reaching to rub her groin as she stepped toward Steven. Tunnel-vision closed in on each side and she could think of nothing except the rubber buried in Steven's rear. Dropping to her hands and knees as she got closer, she was shocked when his tail flopped down to hide the toy.

"You can have a plug when you show me how good a girl you are." The look in Celeste's eyes almost broke Steven of his plan. She looked so forlorn at losing immediate access to a plug that he weighed up the benefits of a good hand-job against just giving in.

"I'm a good girl! I promise! Please?" Celeste just wanted to have her butt filled, but as Steven rolled over she knew what would make her a good girl. Dropping to her knees, Celeste quickly wrapped both hands around Steven's shaft and spat on him a few times.

The look of hungry lust that now colored Celeste's features reassured Steven. She might not have flat out told him this is what she wanted, but she was eager as heck to start on his shaft. When she started stroking, however, all of Steven's clever machinations fizzled and died as pleasure overtook him. Stretching his neck out and lolling his head to the side, his tongue hung out the corner of his mouth and he made soft, happy horse sounds.

Celeste was enraptured by her task. Though thoughts of the plug and needing one of her own still made her squirm a little, it was now an end-goal of getting Steven off. It was simple logic—distract him with an orgasm then claim her reward while he was too overwhelmed to stop her. His shaft was leaking a thin fluid from it after each stroke now, and she cupped one hand then the other over his tip to gather some to make her fingers more slick.

It didn't take Celeste much more work before Steven's excitable libido drove him to the height of pleasure and crashed through every barrier between him and orgasm. While he started whining and spraying his seed all over his chest, Celeste used one hand to hold his rump steady while the other pulled his dock aside.

The plug's base was snugged up to Steven's ponut, held firmly in place by the strong muscles of his rear. She leaned closer and closer to the shape until she could push her lips forward and kiss it.

There was something—like the strike of lightning—that connected the magic of the plug directly to Celeste's head. She nuzzled and licked at the toy, but kissing it seemed to be what her brain (and the toy that was steering her thoughts) was telling her to do.

When the first push of the toy spread her lips, Celeste just suckled on the intrusion. When it worked further into her mouth and started to swell, she moaned around it. As it swelled up to full size, Celeste felt the need to put it somewhere else grow to a fever pitch in her head. Pulling her mouth over and off the plug, she turned around and aimed her rump at it.

The first push reminded Celeste that she was still wearing clothes. Reaching back with her hand, she grabbed her skirt and boxers and pulled down on them to reveal her rear.

Steven, his wits recovering after the mind-blowing orgasm he'd just had, looked down his messy chest and belly at Celeste as she tried to aim her butthole onto the now double-ended butt plug. He was going to say something—even offer to help—but the way she let out annoyed little whines each time she missed was too adorable for him to interrupt.

"What are you giggling at?" Celeste asked, her thoughts becoming a little more lucid as frustration settled on her.

"You're so adorable when you're struggling to do that. Want some help?"

"How'd you line yourself up so—Yes!" Celeste's voice was laden with urgency and need. When Steven rolled over and stood up, she quickly got in position and held herself steady.

Lining himself up where he thought was right, Steven started to push back.

"Wait!" Celeste jerked forward while giggling. "Wrong hole!"

"What, really?"

"Yes! Aim higher!"

"I kinda can't. You need to bring your butt lower."

So Celeste adjusted her legs so she was practically splaying them out to her sides while her belly was just about on the floor. When Steven pushed back this time, she felt the tip of the plug poke her right in the middle of her anus.

Arching her neck and letting out a long whine, Celeste pushed back at the same time Steven did, not even thinking about the need to use lube. Not that the magical butt plug needed lube. The thing pushed quickly all the way into Celeste—with the help of both of them thrusting at once—and joined them together at the plug.

The fullness in her rear distracted Celeste from the shape of her muzzle forming—not that it would have worried her. Everything felt right with the plug in. Celeste's mind became sharply focused again, and without knowing why she pulled forward and the toys split.

Slumping onto her belly, Celeste whimpered and squirmed in her clothes, but as the moments passed by, she realized they were getting bigger on her. She realized the best way to speed things up and turned around. "Gimme that plug."

"Wait, what?" Steven hadn't even realized what she was doing before Celeste had both her hands around the base of his plug. She pulled so fast and so suddenly that his plug shot out before her hands had finished changing into hooves.

The emptiness of his rear filled Steven with acute loss. He shivered and looked back at Celeste. "That was not fair."

"Neither was making me rub you off before I could have my own plug."

Steven wasn't going to be distracted. "Turn around. I want another plug right now, and then I'm going to pull yours out."

"What? After all the trouble I had getting this one in?" Despite her protest, Celeste was already turning around. The truth was she enjoyed things being a little rough and tumble, and the feel of Steven plunging the plug into her had almost pushed her to orgasm.

Steven watched as soft fuzz covered Celeste's rump. The culmination of the changes flowing over her body was a thin whip of a tail that suddenly exploded into a skirt of hair. What got his attention, however, was below the mottled pink and white plug. Nuzzling at Celeste's taint, Steven worked his snout lower and between her back legs (as they became back legs), and finally started nuzzling Celeste's balls.

Celeste's moan caught her completely off-guard—just like Steven's nuzzling did. She widened her stance and lifted her rear as high as she could to let him have better access.

Given free-rein, Steven licked and nuzzled at the heavy orbs that hung down from under Celeste's sheath. Gone was any trace of her femininity (and humanity). "You know how awesome it is that this can happen? You're probably like the first person ever to be able to feel both sides of things."

Three times Celeste tried to formulate an answer, and three times she got as far as opening her mouth when a groan came out and interrupted her instead. It felt amazing to have her balls toyed with—it was the first time in her life she'd experienced it, after all.

Finally, however, Steven's need to have his butt filled was too much. He pulled his snout back from the musky heaven it had been probing, traced up Celeste's perineum, and found his prize. The plug felt like the usual soft, silicone rubber as he nuzzled it, but as shiver of lust spiked through him from the tip of his nose, through his brain, and directly down to his own ponut.

Squeaking in surprise as Steven started nuzzling at the fresh plug in her rear, Celeste looked back at him—past a pink mane and a white coat—and giggled at the sight of two fuzzy ears poking up above her rear. "You doing okay?"

Steven's reply was muffled by the forming plug in his mouth. He suckled and nursed on it as it filled his mouth up slowly. Encouraging the toy and giving-in to his base desires, Steven soon had the plug almost-but-not-quite too big to leave his mouth. Pulling back, he gasped. "It's bigger."

"What do you mean?"

"I mean the plug's bigger than the others."

Celeste was so distracted by her predicament that, on hearing that the plug was bigger, she immediately turned around to have a look. Only when she was facing Steven did she realize what she'd done. "I'm an idiot."

Reaching up with his hoof, Steven booped Celeste on the nose. "Yeah, but you're a horny, cute pony, so you get a pass. Turn back around."

"Is it really bigger? Maybe it's sized to fit you, and you're bigger as a pony?" Turning around, Celeste lowered her chest to the floor and propped her rump up in the air. She loved the feel of the pose mostly because it was offering so much to her partner.

Nuzzling under Celeste's tail, Steven licked all around the base of the double-ended toy and savored the sound of Celeste's happy little pony sounds. The smell of her musk was almost as intoxicating as the toy's effect on his brain, and finally he had to surrender to his need to have the plug inside him.

Turning, Steven used his apparent superpower of being able to line up his butt on a positioned butt plug (a superpower he'd only recently learned he possessed) to its best effect and felt the tip of the toy kiss the opening of his anus. If there was something odd about his recent enjoyment of anal sex, he definitely didn't care as he pushed backwards onto the toy.

As always, the plug slid into him with little resistance, but the deeper it went the wider it got, and Steven found himself biting his lip like it was his first time all over again.

"Are you alright?" Celeste asked when she heard him whine.

"It's really big…" Steven wasn't one to be undone by the toy. He trusted whatever magic was at play to have made it the right size for him, which meant it would go in. So, with no better idea of how to solve the situation, Steven shoved back as hard as he could.

The stretching this time was unbelievable. It felt like someone was trying to shove a football in his rump—the best bit was it did fit in. He opened his mouth and let out a low moan of mind-numbing bliss as the thickest part of the toy settled inside his rear and left him feeling bloated and stretch—and full.

"I want to see." Pulling her rump away from Steven's, Celeste turned and saw the much larger base snugged up against his ponut. "Well, the base of it looks bigger. What's it like inside?"

"Huge!" Steven's legs wobbled and splayed out to each side. His belly and chest hit the floor with a whump, and he let out another whimper.

"You want to know the best bit?"

"What? What's the—?" The feel of Celeste's teeth clamping around the sides of the big plug's base—and the slight tugging at his insides—broke all of Steven's concentration. He let out a little groan. When she braced a forehoof on each side of his rump, he had a horrible idea of what she was about to do. "Wait—!"

Steven was not given the delay he'd hoped for. Celeste yanked on the plug hard—as hard as it normally took to pull the toy free with one pull—but it wasn't enough to do more than make Steven mewl in submission.

Pulling again and again, Celeste had to adjust her legs to brace better before putting all her neck muscles into pulling.

There was a lot of resistance, but Celeste wasn't a weak human at the moment, she was a little pony with the will to get something done. At first there was only resistance, and she was sure Steven was clamping down on it, but then he must have relaxed his sphincter.

The lewdest plop of all time sounded as the plug pulled free, and Celeste could see what Steven had been talking about. The plug was easily double the size of the one she'd taken a little earlier.

"Putitbackin! Putitbackin!"

"No!" Celeste stomped around to Steven's front and glared down at him as best she could. "This was always the plan. You want another plug"—she turned around and flicked her tail up—"come and get it."

Crawling forward, desperate to get to Celeste's rear so he could fix the problem—the hole in his being—Steven let out repeated whines and whimpers until her came nose-to-rump. Resigned to whatever fate would bring, he started licking along her taint and pausing when he reached her butt plug, then repeating the motion.

"D-Damn it, Steven. Just make yourself a—" Celeste's eyes widened in shock when, instead of nuzzling the plug in her rear to make a new one, Steven clamped his mouth around the base of it. "N-No!"

Bracing his hooves, Steven rolled backwards with the butt plug firmly between his teeth and pulled it out of Celeste with a heave.

It was Celeste's turn to slump to the floor and whine at her empty rump. The plugs were so insistent about remaining in their homes that they conditioned people to need them to be there—the sudden loss was like losing part of herself. By the time she got it together enough to turn and query Steven, he had her plug braced on the floor and was in the process of sitting on it.

As soon as his rump met the floor, Steven knew relief. Not only was this plug much smaller than the other, but it was in the right spot—his butt. "Now it's your turn to have something way too big. I bet, since you're a little pony already, you're going to wind up with an oversize one too."

Celeste looked over at the plug she'd pulled out of Steven, and her mind raced to all kinds of wicked places. She'd played with toys in her rear before, but all this craziness was new. New body, new penis—she figured she might as well step things up. "Well, get your butt over here so I can try this thing out."

Standing up, his mind restored to balance now his rear was filled with a toy, Steven walked over to Celeste and kissed her. There was no ifs, buts, or maybes—he kissed her.

For her part, Celeste melted into the kiss and warmed to it immediately. Despite having lived with Steven for years, it'd never felt like the right time to involve herself with him romantically. Until now. Bracing one hoof on the floor, she lifted the other up and rubbed his cheek.

Having initiated the kiss, there was nothing Steven could think that would work in denying how he felt. Rather than close his eyes, he gazed into Celeste's big pony peepers and saw a mirror of what he felt there. Finally, he felt complete.

Breaking the kiss in stages, Celeste couldn't stop going back to Steven's lips for additional little smooches. When they finally parted, she let out a sigh. "We're done, aren't we?"

"Living like we were? Yeah, I think so. I love you."

"I love you too." The words tumbled out in a rush, and it felt good to Celeste to finally be able to say them. "Now turn around so I can stare adoringly into your butt."

Steven giggled and started to turn. "You say the most wonderful things, you know that?"

The moment Celeste's eyes made contact with the butt plug's base, she felt her thoughts unhinge. If she'd fought against it, she might have been able to pull his plug out before it snared her completely, but she didn't want that. She wanted her own butt plug.

Legs turning to jelly as Celeste nuzzled at his rear, Steven let out happy sighs and shuffled a little to expose his rump more fully.

Celeste just let her mind coast as the hypnotic power of the plug slid its mental tendrils through her head. She nuzzled, licked, and booped her nose against the base of the plug again and again, until she felt it start to push back.

The little bud needed no encouragement, but Celeste felt the need to give it anyway. She licked and kissed the growing plug body repeatedly, making hungry, happy noises over and over. When it reached the normal size she was accustomed to, she drew back a little, but it kept growing.

"St-Steven! It's getting bigger!" She stared as the plug reached a larger size even than toy she'd pulled out of Steven. Was it listening to her thoughts? Was it trying to punish her for removing the one she'd had in? "Really big…" Despite any misgivings Steven had had, Celeste only knew need. "I want it in me."

"Turn around. You happen to have a stallion with a superpower ready to oblige you." Steven swayed his rump side to side while looking back, and he couldn't help but giggle at Celeste's head weaving to and fro to follow him. "Celeste!"

Shaking her head to dispell the mental conditioning of wanting to stare at the double-ended butt plug, Celeste took a quick breath. "It's bigger than yours was. Give me a second to turn around."

"Bigger?" Steven asked.

"Yeah. A bit bigger. If it's trying to dissuade me from removing them, it's doing a bad job. Okay, get it in me." She'd braced herself on the floor and lifted her rump. Unlike Steven, her aim was terrible, but it wasn't her in control of aiming this time.

Lining things up, Steven hoped he was on his mark as he leaned backwards. The slightest of pressure back against his rear was the first sign he was on target—Celeste's moan was the second. "You ready for—"

"Just shove it into me!"

Steven shoved backwards hard. Celeste's squeal had not a hint of pain to it, which only encouraged him to push more—since he couldn't feel her rump against his.

Equestria

"You made them bigger?" Dazed Dream stared hungrily into the vision brought to them by Organized's scrying.

Organized Chaos stomped a forehoof in vehemence. "Yes. These two are just playing stupid games and I'm sick of it. I want a stallion to fu—"

"You're an idiot. Can you make them go back to normal?" Smooth Talker was looking at the same image the others were, and her need was just as great, but she saw something neither her co-conspirators did. "These two are our vector. I know you didn't mean for this to happen, but it's going to work out better."

"What?" Organized stared at Smooth.

"Look, these two already got a butt plug into someone else's hooves, right?"

"Right."

"And that creature is now stuck, right?"

"Right."

"Which means these two will spread the plugs to others and provide us many stallions." Smooth watched as one of the stallions managed to shove the huge plug deep into the other's rear. "What are the odds they'll be able to get that out again?"

"Who cares!" Dazed Dream was leaning over the railing and staring up close at the image. "I want to suck one off while the other fucks me…"

"They've been consistently getting them out. It's a matter of time before they forget, anyway, but I think that stallion will be able to get it free. He has bigger things in his drawer." Organized grabbed Dazed with her magic and pulled her friend back. "If you break my scrying device, I'll shove one of those in you."

Dazed Dream just stared at her friend, completely distracted now. "You mean you could have just shoved a plug into any of the mares in town?!"

"Err, yes. But then we'd have a mutiny. The others would know we had some powerful artifacts and try to steal them. Or, worse, everypony in town would have done what these two are doing, and we'd be the only mares in a town full of randy stallions."

All three mares stared at each other in shocked realization, then Smooth and Dazed glared at Organized.

"Fuck. Why didn't I do that?"

Earth

The afternoon was too long for Susan and the night even worse. Her hooves were sore from masturbating and she'd left literal snail-trail over half her furniture while humping at it to get off. Sleep wasn't possible, and all she could do into the small hours of the evening was whine and rub at a penis that would give her no relief or surcease.

In the end, around 1 A.M., she finally closed her eyes and passed out from exhaustion.

At that exact moment the plug in her rear began the final parts of its programming. It merged itself magically with her rear, sealing in place and becoming part of her body—though the base of an obvious butt plug was still visible, as if she still had an anus.

A shimmer of crystalline pattern spread out from her rear, cascading through her flesh and fur and spreading down her legs and along her body. Even Susan's penis and balls became faceted and akin to a soft white diamond.

The final transformation of human woman to crystal pony stallion took place as the crystal pattern covered Susan's face. A little shiver ran through the stallion, and then a loud POMF echoed through her living room.

Equestria

When Susan woke, it was to the sound of arguing. An odd sense of hunger filled her—and all the weariness that had driven her to pass out seemed wiped away. She slowly opened her eyes to see who was arguing and try to make sense of her situation.

"I get to go first!" Organized Chaos said. "Clearly I am the mastermind of this plan, so I get to reap the first benefits!"

"No way! You've been slaking your needs with Dazed!" Smooth Talker said.

"Hi there." Dazed Dream, much as she'd done with everypony in town (excluding Smooth Talker), approached the problem of a new pony directly. "Welcome to Normalville. I'm the mayor here. It's nice to meet you."

Susan had to wipe at her eyes to clear them. It didn't help—she was still looking up at a pony. "What are they arguing about?" She folded her ears back a little at the volume of the pair.

Putting a foreleg around Susan's withers, Dazed guided her to the door. "Well, let's get out of here and leave them to their argument. My name's Dazed Dream, what's yours?"

The friendliness surprised Susan to the point of disarming her panic. She walked beside Dazed and felt an odd kinship with her. "I'm Susan. What is this place?"

"Well, this is a town that Equestria tries to ignore. It's full of mares who have done… questionable things. Not exactly evil enough to be blasted by the Elements of Harmony, but they don't exactly want us out in the world and enslaving our own harem of stallions, if you know what I mean?"

"N-Not really. Wait, mares, stallions… Is this a world full of ponies?"

Dazed led Susan out into the morning light. Equestria's time moved differently to Earth time, and so it afforded the first human traveler (for given values of human) their first look at another world. "Wow. This is pretty…" Susan's head started to swim and she turned to look at the mare at her side—nose twitching.

"Quite the sight, eh?" Dazed realized the look Susan gave her was the exact effect of a stallion catching the scent of a mare heavily into her estrus. That particular look meant Dazed wouldn't even need to use her special talent to seduce Normalville's first stallion. "Something wrong, Susan?"

"Y-Y-You smell good." The words weren't from the smart places of Susan's brain, those were in the process of enjoying a sauna of serotonin that left it unable to work at any level of efficiency. Thankfully, the more base and animalistic parts of her brain were up to the task of carrying out this most basic of conversations. She leaned in to Dazed and inhaled from the ruff of the mare's mane. "Really good…"

"I have just what you want. Come on, Susan, let me show you why I'm the mayor of Normalville."

Author's Note

Ask Organized Chaos: Haven't you put a function for you to manually summon your target to your baits?

Tapping her chin, Organized shook her head after a few moments. "I mean, if we did that the poor things would never get any time to themselves. Besides, the way this works, they'll totally think it's all just a strange dream. It's perfect!"

So I do this "Ask X" thing. X can be any pony within the story. You can ask them anything and they will definitely, hopefully reply. Keep the questions appropriate to the age-rating of the stories, and they will answer the best question in the author notes of the next chapter. The more votes a comment has the more likely I will get it to the right pony to answer. Try to keep it to one question per post! They will pick one question per chapter.
