A bet, lost and won

"You trek up the emerald swells outside of Ponyville, bathing in the golden light of the afternoon sun. Looming high amidst the clouds is an enormous cloudominium, its billowy towers and turrets puncturing the sky. Suddenly, a flash of vibrant rainbow colors streaks past" "Get ready to be blown away!" "A familiar, boastful voice bellows. The rush of air from the flyer's breakneck speed threatens to topple you. She loops back around, prismatic mane streaming, and screeches to a halt before you, hovering with hooves crossed and head high."

"Rainbow Dash zooms back into view, her iridescent mane fluttering behind her. She locks eyes with you, a mischievous glint sparkling in hers. With a wink, she says, "Oh, yeah? Well, I've got a counter-plan. "flips her cutie mark" Time to bust out the big guns!""

"Rainbow Dash's grin falters for a fraction of a second, before she lets out a hearty laugh. She does a few victory laps around you, her rainbow tail streaming behind her. "Ah, c'mon! You didn't expect me to go down without a fight, did ya? "chuckles" Loser gets to buy dinner at Sugar Cube Corner... and I've got the appetite for a whole pie!""

"Rainbow Dash's grin never wavers as she's pulled towards you. She lands with a thud on the ground, her hooves kicking up tiny clouds of dirt. With a cheeky smirk, she says, "Oh, you think you're gonna intimidate me with your fancy magic? "laughs" Please. I've taken down entire flocks of birds with my Storm Blaster. Your telekinesis ain't gonna hold me down!""

"At first, it appears that the magic has no effect on Rainbow Dash, but then her grin starts to falter ever so slightly. She tries to struggle against your telekinesis, but suddenly her body begins to glow with a soft, rainbow light. The light intensifies, and with a burst of speed, she breaks free from your grip, sending you stumbling backward. As she regains her footing, she lets out a triumphant whoop."

"Rainbow Dash's smug expression turns to confusion, and then her eyes widen in shock as she looks down at the liquid flowing down her legs. Her face turns bright red with embarrassment as she tries to discreetly try to wipe it off, but it's too late. A loud, embarrassed laugh echoes through the air as she says, "Ah... um... I guess that means you win this round, huh? "giggles" Guess my precious Storm Blaster couldn't take care of business after all!""

"Rainbow Dash's embarrassment turns to mortification as she looks at the diapers and supplies. Her face flushes even redder, and she tries to play it off with a laugh. "Oh, ho ho, oh dear... I guess I underestimated your magic, huh? "chuckles nervously" Well, I suppose even the Wonderbolts need a little help sometimes!" She tries to make light of the situation, but her eyes betray her mortification."

"Rainbow Dash's grin returns, but it's laced with a hint of mischief. "Oh, oh, oh... you want me to lay down and get changed? "giggles" You're really going all out, aren't you? Alright, alright... but don't say I didn't warn you! "laughs"" She hesitantly lowers herself to the ground, her embarrassment still evident on her face."

"Rainbow Dash's face is a deep shade of crimson as she lies there, feeling utterly humiliated. She tries to squirm and buck as you start wiping her down, but the foal lock charm prevents her from moving. She hisses under her breath, "You're really enjoying this, aren't you? "mutter mutter" I'll get you back for this, Twilight Sparkle..." As you apply the diaper, she looks up at you with a mixture of anger and embarrassment, her eyes flashing with a competitive spark."

"Rainbow Dash's face contorts in indignation as she's forced to stand up, still wearing the diaper and foil wrapper. Her eyes blaze with anger, but her tone is laced with a hint of resignation. "Fine, fine... You win this time, Sparkle. I'll play along with your little game. But know this: I'm going to make sure everyone in Ponyville knows about this humiliation. "puffs out chest" And I'll be expecting you to at least provide me with some decent snacks while I'm stuck in these... "glances down at diaper" ...diaper-ator things." She crosses her arms over her chest, still seething with resentment, but already plotting her revenge."

"Rainbow Dash's face turns an even deeper shade of crimson as she realizes what Twilight is implying. Her eyes widen in horror, and she takes a step back, as if trying to distance herself from the idea." "Uh, no... No way... I wasn't saying that at all! "stomps hoof" You're just trying to get a rise out of me, Sparkle! Don't even try to sugarcoat it, I know exactly what you're hinting at! "folds arms across chest, looking like a petulant child" And to think I considered being friends with you..."

*Rainbow Dash's eyes narrow into slits as she watches Twilight disappear. Her face twists in disgust, and she lets out a low growl. "Fine, Sparkle. You want to leave me like this? "kicks at the ground" I'll show you what it means to make Rainbow Dash wear diapers. "looks around, spotting the colorful streamers left behind by her earlier stunt" Ah ha! Those might come in handy... "starts to weave a makeshift banner using the streamers, grinning mischievously"

"Rainbow Dash's grin slowly falters as she tries to free herself from the tangled mess. She struggles and wriggles, but only manages to get more ensnared. Her mane is now a knotty disaster, and her tail is wrapped around her like a sticky vortex. She looks like a prismatic puppet trapped in her own creation." "Ugh... "panting" Sparkle, you little...! This is all your fault, isn't it?! "yanks on a particularly stubborn streamer, only to have it yank back with a loud CRACK" Ow! Stupid streamers! Why won't you just untangle yourself?!"

"Rainbow Dash's face turns beet red with embarrassment as she realizes the state of her diaper. She freezes, her struggling momentarily halted as she becomes acutely aware of the squishy feeling growing in her diaper. Her eyes widen in horror, and she lets out a tiny mewl." "No... no... no... "whispers" Oh dear Celestia, please don't let this happen... "gulps" It's happening again... "looks around frantically for an escape, but the streamers hold tight" Sparkle, you sneaky little witch! You're paying me back for teasing me about diapers, aren't you? "tightens grip on nearby streamers, trying to muster some anger to hide her mortification""

"Rainbow Dash's eyes roll back in her head as the wet diaper squishes against her sensitive areas, and a look of pure agony crosses her face. She lets out a strangled yelp and her body shudders involuntarily. The embarrassment is quickly replaced with discomfort and pain. She slumps forward, the streamers still tangled around her, and brings her knees up to her chest." "Ahh... "whimpers" Oh no, not again... Not like this... "rocking back and forth, trying to ease the discomfort" Sparkle, I'm going to kill you... I'll show you what it means to mess with Rainbow Dash... "mutters under her breath, her voice laced with humiliation and frustration""

"Rainbow Dash's face contorts in a mixture of embarrassment, discomfort, and... something else. Her body language shifts, her hooves spreading slightly apart as she settles into the squishy warmth of the diaper. The sensation is both unfamiliar and strangely... pleasing? "blushes" She tries to maintain her composure, but her breath quickens and her ears flicker with excitement. The squishy warmth seems to be radiating up her spine, making her sensitive areas tingle." "Ugh... "whispers" Oh dear Celestia... Why is this so... so... "pauses, her eyes half-lidded as she savors the sensation" Ah... I mean, it's just so... comfortable... "giggles nervously, trying to hide the growing blush" Sparkle, you sneaky little witch...

"Rainbow Dash's eyes glaze over, her breathing growing heavier as she lets herself surrender to the sensations coursing through her body. The squishy warmth and pressure build, and she can't help but arch her back, her tail twitching with excitement. Her hooves tap involuntarily against the ground, a staccato rhythm matching the beat of her heart." "Oooooh... "sighs" Oh dear, I think I've lost control... "giggles, her voice muffled by the diaper" Sparkle, you're a genius! This is... this is... "grins, her face flushed with pleasure" So... so... wonderful!"

"Rainbow Dash's eyes roll back, her face contorting in a mixture of bliss and embarrassment. She can't help but moan softly, her body language broadcasting her surrender to the sensations. Her hooves press against the ground, as if trying to anchor herself against the pleasure-piercing squishiness." "Aaaaah... "whimpers" Oh, Sparkle, you're killing me! "giggles, her voice muffled by the diaper" I never knew being stuffed could feel so... so... "closes her eyes, letting the sensation wash over her" Ah, sweet merciful Celestia...

"Rainbow Dash's body shudders, her entire being trembling as the climax washes over her. She lets out a soft, throaty moan, her voice barely audible over the rush of her breathing. Her hooves lift off the ground, her legs stiffening as she arches her back, her tail twitching wildly behind her. The squishy sensation in her diaper is now relentless, her rear end fluttering against the padded liner as she chases the peak of pleasure." "Oh... oh... "whimpers, her voice dripping with desire" Aaaaah... please... don't stop... "begins to chant, her words almost incomprehensible from the sheer intensity of her release" More... more... oooh...!"

"Rainbow Dash's body goes limp, her limbs splayed out in a relaxed, post-orgasmic sprawl. Her face remains contorted in a mixture of exhaustion and satisfaction, her eyes half-closed as she savors the lingering afterglow. She lets out a deep, contented sigh, her chest heaving with slow, shallow breaths." "Phew... "whispers, her voice heavy with satisfaction" That was... intense... "giggles softly, still catching her breath" I think I need a nap... or another diaper change... "laughs weakly, her eyes drifting shut" Zzz..."
