Daybreak carried her prize out into a little stone courtyard, setting her down on her ass. Sunny let out a squeak as the butt plug pressed deeper into her poor ass, and for just a moment the edges of her vision dimmed again. She knew that she probably couldn’t take much more, and that orgasming now might just knock her out.

“Please...I can’t take much more, Mistress Guardpony!” she yelped, looking up at Daybreak pleadingly before several other figures caught her eye.

As she looked around, she caught sight of Sky leaning against a tumbledown pillar, grinning at her with a self-satisfaction that might be infuriating...if Sunny had any energy left to be infuriated with.

“You’re almost as pink as the batpony, Daybreak,” she crooned, stepping forward and hoisting Sunny to her feet. “She really did a number on you, didn’t she?”

“Bite me!” Daybreak replied ever-so pleasantly, taking Sunny’s other arm in her own. The two mares practically sandwiched Sunny between them, both grinning at her in a way that seemed to say “You’ve really fucked up, Sunny.”

“You wish I would,” Sky said, sticking her tongue out at the big brown pony. “So, Booty Bat, have you learned an important lesson today?”

Sunny opened her mouth to speak, but Daybreak clapped a hand over her muzzle to silence her, now grinning with the air of a born tattle-tale.

“Not so fast, Sky,” Daybreak said silkily. “Sunny here didn’t quite manage to get me off, and she also pleaded with me to turn off that vibrator you so graciously gave her!”

Sky gasped, feigning offence. “You did?”

“Mmmph! MMMMPH!” Sunny howled through Daybreak’s fingers, eyes going wide at the damning testimony. Sure, she’d been a bad bat, but surely she’d made up for it, right?

“Hmmm, well, it seems to me that what our little friend here needs is some severe punishment. Daybreak, be a dear and get our emergency equipment set up, would you? Oh, and make sure to walk away reeeeal slow. That booty isn’t going to admire itself.”

“You’re going the right way for a smacked bottom, buddy,” Daybreak said with a grin, though as she walked away, she did indeed sway her hips, tail swishing from side to side for Sunny’s benefit as much as Sky’s.

“I tell you what, you think you’ve had problems, I’ve had to put up with her,” Sky said, patting Sunny’s ass to get her moving as well. “Now, tell me, besides that stunt you pulled back in the swamp, how are your acrobatics?”

“Er...they’re...okay, I guess…” Sunny whispered, keeping her knees locked together as she tried to fight off those last tingles from the vibrator...not to mention the otherworldly discomfort of that toy in her ass. “Wh...why? I’ve learned my lesson! I promised to be a good little bat!”

Sky looked her over. Sunny’s makeup had run a little and there were tear-tracks down her cheeks from the torturous treatment she’d had over the last little while. Any other pony would probably have felt a twinge of pity.

“And what was that lesson?” Sky asked, smirking slyly at her good little sub.

“I...I’ve got to be a polite little batty...and I /wiiiiill/...just...plea...please let me cuuuum!” Sunny yelped, the squishing together of her thighs only forcing her ass to clamp tighter around the plug. “Pleease, before anypony sees me all naked like this! You don’t want anypony seeing my titties, do you?”

Sky paused, scoffing. “Then what’s coming next for you is gonna make things kinda awkward...just saying,” she said. “You’re gonna pay for not pleasing your mistress, Sunny Bunny, and we’re gonna show you why we’re the wrong mares to piss off.”

She stopped by a bench. “Bend over,” she said simply.

Mind clouded by hormones and the feeling of her soaking pussy radiating heat, Sunny complied almost immediately, looking back over her shoulder to see what on earth Sky could be doing. The crippled white pegasus cupped a hand around Sunny’s ass cheek, giving her a little squeeze to coax a squeak out of her obedient, adoring little sub.

“Please...mi...mistress...can you...please fuck my poor little pussy? I neeeeed it…” Sunny begged, legs threatening to buckle underneath her as Sky forced her to bend over a little further. “I’ll be good! I’ll be super polite, I promise!”

“Yeah, I bet you will,” Sky whispered noncommittally, grasping the flared base of the butt plug and tugging on it very gently indeed. Sunny let out a yowl as she felt that tight discomfort all over again, her asshole squeezing around that very tight toy. She gasped and let her tongue hang out of her open mouth as Sky played with it, almost impassively, as if wondering what will happen.

“Eeeeep! Ple...pleeeeease…” Sunny began, but Sky drew back a hand and slapped her ass to cut her off.

“Shut up, slut,” she growled. “You don’t get to demand anything. In fact, you’re lucky I don’t tape over that pussy of yours so that no one can get at it, not even you. You’ll take the punishment you’re fucking well given, and you will thank your mistresses at the end of it. Maybe…maybe...then I’ll think about helping you get yourself off. Do I make myself clear, bitch?”

“M...mhmmm…” Sunny murmured, swaying her butt from side to side as Sky played with the toy in her ass, sliding it out a little way just to stretch her asshole out, a little bit at a time. Sunny’s toes curled in her boots, her numb restrained hands balling into fists. A little drool dripped down from her open mouth onto the ground from Sky’s expert ass play.

“See? Much more quiet…” Sky purred, nipping at Sunny’s ears again. “You’re learning...though we’re still gonna make you suffer, so don’t start thinking that you can go around buttering my bread to get out of this…”

Sky slowly, palpably slid the butt plug out of Sunny’s ass, little by little, just to make the sensation as intense, tight and uncomfortable as possible. Sunny nearly collapsed as soon as it popped out, feeling at once warm and yet...way emptier than she’d been before.

“Wha...what happens now, mistre...mistress?” She asked timidly, as Sky steered her towards where Daybreak had wandered off to.

“You’ll see…” Sky said quietly. “Now, let’s cut you down to size, shall we?”

They rounded a corner, where they found Daybreak standing with what looked like a pair of nooses and a very sizeable dildo on a stage. Beyond that sat a stone archway with the same swirling green energy within that Sunny had seen in the chest earlier. She suddenly felt very worried indeed.

“Do you think she’s ready?” Daybreak asked, curious.

“Oh, she’s lubed up and stretched out. I think she’ll do juuuust fine,” Sky replied, steering Sunny up onto the stage to join her captor.

“Wai...wait...I have to...take that in my ass?” Sunny squeaked, eyes on the thick, long dildo. It looked easily big enough to make it difficult for her to walk. “You...you’ve gotta be kidding me...it’ll never fit!”

“Well, whether or not you take it in the butt is up to you,” Sky said. She lifted Sunny up by the butt as Daybreak threaded her legs into the nooses. By the time she was finished, Sunny was suspended over the dildo with her legs spread and her butt hanging just a foot over the tip of the oversized toy. “We’re gonna ask you some questions, and if you get them right, we let you go. If not...well...tell her, Daybreak.”

“It’s a cursed dildo,” Daybreak said proudly, nodding. “You take it in the butt and you’ll feel like it’s fucking you there for the rest of the day...and that’s probably gonna make your little desperation problem even worse.”

“Bu...but I don’t wanna get fucked in the ass! Pl...please, mistress...don’t stick anything else there! Fuck my pussy instead! Ple...eeeeeease!”

Sky narrowed her eyes, loosening the rope by a notch. Sunny descended a few inches towards the dildo, squeaking and flicking her tail from side to side worriedly. She glanced down at it before looking back up at her captors, struggling to resist the urge to bite her lip. She had to admit...to herself, at least...the idea of being in such a risky state was kind of hot...in a torturous sort of way. As much as Sunny tried to squeal and whimper and beg and plead, her pussy juices dripping down between her legs onto that dildo were a dead giveaway.

“What did I say about demanding things?” Sky asked, tapping her foot impatiently. “You don’t get to demand shit, got me?”

“Ye...yes, mistress! I don’t get to demand anythiiiiing!” Sunny agreed, nodding her head urgently. She stopped as soon as she realised it was making her body swing a little. The last thing she needed was to slip and end up with that dildo balls deep inside of her poor little ass.

Daybreak stepped forward, running her fingers through Sunny’s mane and squeezing her ear between thumb and forefinger. “Now that we have your attention...questions,” she whispered. “Number one...what were you in trouble for in the first place?”

“Be...being...a naughty little batty…” Sunny blurted out. “I was...very rude...and hit a stallion in the face...and he didn’t deserve it!”

“Well, it’ll come as some consolation to you that he was the first one to nut all over your face,” Sky said, looking clearly disappointed that she didn’t get to lower Sunny down any further...yet.

“Next question,” Daybreak continued, scratching Sunny behind the ears, “what are you going to do when you see that poor little stallion again?”

“I’m...gonna...say...so...sorry?” Sunny gulped. “I...I’m gonna say sorry...for being such a rude nasty bat…”

Sky huffed, blowing her mane out of her face. She clearly hadn’t wanted Sunny to get these right.

“Good job, Sunny Bunny,” Daybreak crooned, smooching Sunny on the cheek and stepping back. “Now, let’s try a harder one. Who were your mistresses today?”

“O...oh no…” Sunny gasped, realising to her horror that she hadn’t caught the guardpony’s name. She knew that Sky had said it at some point, but she couldn’t remember for the life of her.

“Um...Sk...Sky...and...er…” she gulped. “Ca...can I pass?”

“I dunno,” Sky said, grinning wickedly. “Wanna risk it? You can totally pass if you want to…”

“Ye...yeah...I’m gonna pa...AAAAAH!” Sunny squealed as Sky loosened the rope by another notch. She was now only a couple of inches above the dildo, close enough to feel the magic radiating off of it, making her butt tingle.

“Sorry Daybreak, you should’ve been more assertive with her or she’d know your name,” Sky said with a shrug. Daybreak waved her off, striding towards the batpony with a determined glare.

“Last question…” Daybreak whispered. “This one’s a make or break deal, just so you know. Where do you think that this dildo is gonna end up?”

“Um...um…” Sunny gulped again, ears flicking and swivelling as she went bright red under the guardpony’s interrogations. “My...my bu...my butt?”

Sky and Daybreak exchanged a glance. It was a decidedly evil glance that suggested that that last question had been a rather clever trick. Sunny’s eyes went wide.

“No, wait! Wait!” She squealed, as Sky slipped the rope loose. “No, no wait, NOOOOOOOOAAAAAAAAAH!” her pitiful attempt at bargaining turned into a breathless scream as she dropped onto the dildo. Against all of the odds, it did slide into her ass, but only because of the entirety of her weight being focussed on that one point. Sunny yelped and squirmed as it slid in by inches, bursts of magical sparks shooting up inside of her as she took more and more of the toy by the moment. It squeezed the breath out of her, and for a time she was light-headed and maddened by the feeling of the intruder in her ass. Her limbs twitched and spasmed under the duress, and for a while it even felt as if she’d fall unconscious from the sheer size and feeling of that thing.

And then, mercifully, Sky and Daybreak pulled her off of it. Just as she’d sunk down onto it by inches at a time, so too did the two mares help her off of it nice and slowly. It wasn’t long before Sunny was back on her feet, free from the dildo at last.

Or so she thought. After a few moments to catch her breath, Sunny noticed a weird pressure around her ass. Looking back at herself, she saw nothing, but it was certainly there. Something almost identical to the feeling of a stallion working his dick into her butt, slowly but palpably. No matter how Sunny moved or where she walked to, she felt the very same thing, until finally she let out a yelp as that phantom dick drove deep into her ass, practically knocking the wind out of her.

“Aa...AAAAH!” She wailed, falling to her knees as that cock slammed into her ass again and again, with enough force to buckle her legs and shake with sheer unbridled lust. “Noooooo...not...aaah...not my...aa...aaaaass! Pleeeeeease...fu...fuck my pussy! I need to...cu...cuuuuum!”

“Well, you should’ve answered that last question properly, then,” Sky said, as Sunny squealed with each powerful thrust of a dick that simply wasn’t there. “Now, I think you’ve learned all that we can teach you, so it’s time to go back to Canterlot! I bet you can find all sorts of ponies to fuck you there!”

“Wa...wait...you can’t...send me back...li...like this…” Sunny gasped, doubling over even more as the pounding sped up a little. It felt as if her flanks were being squeezed together, making her poor little booty somehow even tighter and sensitive. “No...not...tied up...and naked...with a cock in my ass...someone...someone’s gonna seeeee!”

“Oh, come on, only your hands are tied up, and you’ve got a shirt on, technically,” Sky said, patting Sunny’s bound wrists as she squirmed. “But if you’re so sure that we should help you, there might be something we can do.”

“Re...really?” Sunny yelped. “Li...like what?”

“Ever ripped off a band aid really quickly?” Sky answered.

At that moment, Daybreak picked Sunny up and carried her over to the archway. The poor little bat kicked and screamed in the guardpony’s grip, squeezing her cheeks together to conceal her pussy...which just made her tighter for that invisible cock that slammed into her butt again and again. She felt her ass being stretched wide even as Daybreak set her down at the entrance to the portal, smacking her on the butt to push her closer to it.

“Bu...but what if somepony sees?” Sunny begged.

“Then it’ll be an important lesson. Now, let’s not wait for your next violent crime to get together!” Daybreak laughed, shoving Sunny into the aperture.

* * *

Sunny was launched out of the chest onto the floor in a tangled heap, bunching up some of the makeshift carpet of the pavilion with the force of her impact. Even then, she couldn’t stop whining and yelping as that invisible cock pounded her poor sensitive ass again and again, compelling her to cry out and drool and twitch and flail. All the same, she struggled to get to her feet, gasping and grabbing anything that could make for a decent handhold.

As she looked around the pavilion, she caught no sign of the old mare, nor of Sky and Daybreak. She was alone in there, totally naked save for a shirt-cum-manacles, and the noise from beyond the pavilion suggested that the crowd out there was much larger than it had been.

Sunny was caught out in public, naked, noisy and with a cursed cock in her ass for goodness knows how long, and somehow she was meant to get home and change into new clothes without anyone seeing her.

As Sunny bit her lip, collapsing at the entrance of the pavilion in full view of everyone in the marketplace, she just managed to shuffle into a face down, ass up position, taking her pounding with damningly loud squeaks and deep ragged breaths. One thing was for certain: she’d learned a lesson about manners, all right.

Author's Note

Sky sat down on the stage, prodding the oversized dildo with one slender white finger.

"Do you reckon she's learned a lesson?" She asked.

"Not in the usual way, but yeah, I think she's rehabilitated," Daybreak replied, sitting down by Sky's side and tilting her head a little. "What, don't tell me you were in it for the rehab itself?"

"Pfft, nah, I was asking in case I get to go round two with that batty bitch," Sky giggled, picking the toy up and examining it. "Where the hell do you even get one of these? I might grab one for my collection."

"You've got a weird collection if that fits in it," Daybreak observed.

"Eeeh. I'll make it fit," Sky said, beaming.

"Was that an innuendo?"

"...Maybe."
