"You ready to get out there?" said Rainbow Dash, slapping you on the ass with her huge hand. "You're part of the show now, hot stuff!"
"How 'bout you get in a little more practice before we start?" says Applejack. She sets her massive, muscular frame down on the changing table and kicks her feet up. "Diaper me, cutie!"
You obligingly reach into the 24-pack of Performance Diapers and take one out. It looks huge in your hands, which makes it just the right size for the nine-foot-tall mare you're going to put it on. You wrap the diaper around Applejack's midsection and tape it up, and she stands, patting her bottom. "Nice job," she says, reaching down to wrap her arms around you. "You're gonna do great out there, sexy." She plants a kiss on your lips, her huge mouth enveloping yours.
"Yeah," says Rainbow Dash, "You're the best!" She wrestles you out of Applejack's arms, picks you up, and smashes you between her tits with a meaty bearhug. She tries to one-up Applejack's kiss, filling your mouth with her huge, thrashing tongue. "Okay," she says, setting you down, "Now do me." She hops up on the table and lifts her thick legs in the air, and you diaper up her naked bottom.
Dash hops down from the table she stands beside Applejack. "All right," says RD, "looks like we're ready." The two of them are completely, hugely nude, aside from the Performance Diapers you just put on them. Performance has been the sponsor of RD and Applejack's shows for the past month, and they haven't worn any other brand for diaper in that time. That's for contract reasons, of course, but there's no denying that they're effective at holding AJ and RD's queen-sized dumps.
The sponsorship has been going great, and now that the company has ordered longer shows, the girls need you - their designated diaper changer - to come out and change them onstage. You're nervous, but it's not like you haven't changed their diapers a thousand times before. This'll be exactly the same, just with a crowd watching.
"We'll give you a holler when we need ya," says Applejack. She pats her butt again. "I'll make sure to fill these nice and big for ya, all right?" you nod.
"Me too!" says Dash. "I'll give you a big stinkin' load to deal with, so you better be ready!"
They move to opposite ends of the backstage, and wait for the announcer to get the show started.
"Fillies and Gentlecolts," booms the announcer, "Performance Diapers is proud to present Applejack and Rainbow Dash!" The girls make their entrance, showboating for the crowd, pausing every now and then to pose their massive bodies.
"All right!" says Applejack, "I wanna thank all y'all for comin' out tonight! And I wanna thank Performance Diapers for bein' our sponsor! They're the only diapers I trust with my load!"
"Hey Jack," says Rainbow Dash, "You wanna start with some arm wrestling?"
"Oh, you KNOW I'm ready for that," says Applejack. They both take their seats at the table in the middle of the stage, slam their elbows down, and clutch each other's hands. RD does a three-count, and the match is on.
Almost instantly, the girls start filling their diapers, to no one's surprise. Each grunt of effort, as they struggle against each other, is accompanied by a loud BLORTCH as they poop themselves. They're not holding anything back - the poop piles up in their diapers faster than you ever remember it happening in their previous shows. Knowing that they can call for a change at any time during the show is emboldening them, letting them use their full strength. And the crowd is loving it. The mares in the stands are already starting to poop their own diapers - out of excitement rather than effort.
Eventually, Rainbow Dash pins Applejack - a surprise victory! A huge blast of shit explodes into AJ's diaper as she expends the last of her strength trying to fight back. "Whoo-ee," says Applejack,"Ya beat me fair and square, Dash! And you know what..." She stands and looks down at her diaper, which is sagging halfway to her knees. "I wasn't expectin' to need a change this early in the show, but darned if I haven't pooped myself somethin' fierce already! Hey, changin' boy!"
That's your cue! You wheel the changing table out onto the middle of the stage and shoot a nervous smile to the audience.
"This here's our changer!" says Applejack. "Ain't he just the cutest?" The audience responds more enthusiastically that you expected, whooping and hooting. For you. "He's been changin' our stinky diapers backstage ever since we started performin', but this is his first time onstage. How's he doin' so far?" The audience cheers again, just as loud.
"All right," says AJ, hefting her sagging diaper with one hand, "You think you can handle my big, poopy, stinky diaper, changin' boy?" She wiggles her ass, playing it up for the crowd. That's not to say she doesn't tease you like this in private - they both do - but she's getting an extra-big kick out of it now. Rainbow Dash is smirking, clearly enjoying it too.
You nod, and Applejack grins. "You sure you can deal with all this?" she says. She turns around and shoves her diaper in your face, squishing it against you. The girls' height puts their diapers right at face level, and this is one of their favorite ways to tease you. The crowd loves it too - they've been cheering more since you came onstage than when it was just the girls.
And you certainly don't mind having a face full of AJ's messy diaper. The smell of her poop is strong an earthy, like the pony herself, and it's always a welcome addition to your day. Fortunately for you, she fills a hell of a lot of diapers, even on the days she's not performing, and she gives you the pleasure of changing every single one.
"Ooh, you like that, changin' boy?" says Applejack, pressing her mushy diaper harder into your face. "You like the way my poopy diaper smells?" You can't really respond at the moment, but the answer is still yes. AJ's really getting into this, giving the crowd more of what they want to see. "Teasing the changer" is becoming an unexpected hit, and Applejack is a good enough performer to take advantage of that. Plus, it shows off the sponsor's product.
She lifts her diaper from your face and steps toward the table. "All right, enough foolin' around," she says, "Time to let our changer do his job." She lays down and lifts her legs, and you take your place between them.
Just as you reach out your hands, Applejack catches the back of your head and pushes it down into the sagging mass of her diaper. "Okay," she says, "A little more foolin' around." The crowd laughs. again your senses are overcome with the wonderful stink of Applejack's poop. As your face is down there, she poops again, releasing a wave of odor into your nostrils. It's heavenly - when she releases you, you almost don't want to lift your head. But you still have a job to do. You take the old diaper, tape it up, and clean off Applejack's rear, then apply a new diaper, making sure to position the box to that the Performance Diaper label faces the audience. And speaking of the audience, they are loving the onstage changing; you blush as some of the mares in the front row yell that they'd love for you to change them.
"Whoo!" says Applejack, standing from the table, "Nothin' like a fresh diaper change from the world's best changer! Can't promise I'll keep this one clean for too long, though!"
You start to wheel the cart offstage, but Dash throws an arm out to stop you. "You know what, little guy," she says casually, patting her mushy diaper, "I'm gonna need a change pretty soon. Why don't you just stay onstage?"
Your mouth hangs open. You hadn't considered that you might have to stay onstage after the changing - but you also hadn't imagined that the crowd would love you. Silently, you nod and remain on the stage, behind Rainbow Dash and Applejack.
"All right," says Dash, "How would you feel about a little sumo match?" Applejack nods silently, and they take their places in a circle marked off with tape. They stand with legs apart, arms poised, staring each other down. Dash raises her right leg, grins, and farts, releasing a little more mess into her diaper. Applejack mirrors her, lifting her own leg and pooping her diaper. Applejack's a little freer with filling her diaper, since she's starting off with a clean one.
Then they lumber toward each other, keeping their stances wide, and meet each other in a grapple. Applejack gets her arms underneath Dash's, and pushes her off balance, soiling herself considerably as she strains to push RD over. Most of your attention is on Dash's diaper, though - unless Applejack unloads mercilessly into her diaper, Rainbow Dash is the one you're going to have to change next.
RD's diaper bulges further and further, as the effort of keeping her balance pushes more poop out of her. She backs toward you as Applejack pushes her to the edge of the ring, bringing her growing diaper within a few feet of your face. The smell of RD's poop fills your nostrils, and your heart lifts with excitement as you anticipate changing her.
Dash shifts her weight to the side, and unloads another sizable dump into her diapers as she put her strength into pushing Applejack out of the ring. Applejack stumbles, shitting herself in the process, and while she maintains her balance, one of her feet hands outside the ring. The two of them relax, and they exchange a fistbump. "Yer off to a strong start," says Applejack, "But it looks to me like yer ready for a change."
"You're not wrong," says Dash. She reaches her hand back and tests the weight of her diaper. She has to lean down to get her hand underneath it - it's so full of her poop that's it's sagging nearly to her knees. "We both filled our diapers pretty quick! Having our cute little changer here just makes me want to fill 'em as quick as I can, so I can lie down on that table and let him take care of me!"
She steps toward you, and you begin to wheel your table towards the center of the stage. But she places a hand on your chest. "Hang on, little guy," she says, with a broad smile on her face, "AJ got to have her fun with you. You think all I want from you is a change?"
The crowd laughs, eager to see what she'll do with you. Dash wastes no time, grabbing you by one shoulder, spinning her body around, and smushing her diaper in your face. The smell of Dash's poop - as one might expect - isn't as earthy as Applejack's. Lighter. Difficult to describe. You couldn't say for sure which one you prefer, you're just happy that there are two mares in your life who poop a lot and are happy to let you change all their diapers.
And the presence of the crowd has made Dash all too eager to tease you - and to one-up Applejack. She pushes you to the ground, and as soon as you land on your ass, she descends on you, bringing the big mushy mass of her diaper down onto your face. You know what's coming, and you take a deep breath before her diaper completely envelops you. The air you breathe in is rich with the scent of RD's poop, and it gets over more overpowering when her poopy diaper completely envelops your face.
You don't exactly mind having your face covered by Rainbow Dash's stinky diaper, but there's not a lot of air underneath. The air that is there is permeated by her wonderful poopy smell, but it's not enough to fill your lungs, and you start struggling underneath it. You hear a muffled cheer from the crowd as Dash taunts you with words you can't quite make out. She wiggles her diapered ass, mushing it down into your face.
In the end, she relents, and she lifts her ass off of you. "Heh heh!" she laughs, "Did you have fun making out with my stinky diapered butt, little dude?" You smile wearily, and nod. Being suffocated under her diaper is pretty intense, but it's also pretty damn hot.
"I thought so!" she says. She stands on tiptoe and points her butt at you again. "My poopy diaper butt misses you already. How about you give it one last kiss?" The crowd cheers, and you lean in and plant a kiss on her sagging diaper, savoring the smell of her poop once again.
Dash steps away from you and stands next to the table. "All right! Well, out with the old!" You take your place beside the table as she hops up onto it. She's created a pretty big cleanup job for you; her diaper was even messier than Applejack's, and she put a lot of energy into mushing it around on your face. But you get her cleaned and diapered, and she hops down from the table with a grin. "Give our changer another big hand!" says Dash, "He's a really good sport, you know? Which is not to say he doesn't like the way we play with him..."
You wave to the audience, and they whoop for you again. Being a part of the show is still nerve-wracking - but the crowd loves you, and more importantly, Rainbow Dash and Applejack love you. And they have a wonderful, fun, and stinky way of showing it.
