Diamond Tiara tried really, really hard. She was supposed to be nicer these days. After all, her friends in the CMC had rubbed off on her, and made her try to change her ways. Unfortunately, it also soured her relationship to her mother, further dividing the already distant pair. These days she did her best to avoid her, despite the protests of her father.
That was, until she'd tagged along with the CMC at their request on a routine trip to Zecora's hut. The shamaness had taken Apple Bloom under her proverbial wing, teaching her potion-crafting until she'd halfway mastered the art. When her friends were gathered around the bubbling cauldron, listening to their hostess rhyme, she'd swiped a number of concoctions; whatever she thought might make her mother more pliable. A little docile, kinder, gentler.
Sure, it was wrong. Her insides twisted, but she knew Zecora would never hand over what she wanted, no matter how hard she pleaded, and she promised to somehow pay her back eventually. Shouldn't be hard, she decided with her rich lineage! Plus, it brought her back to the old days, when she and Silver Spoon turned to theft for kicks and attention.
Tucking the pilfered items into her purse, she strolled alongside her companions down the path back to Ponyville. Her dainty hands were clasped behind her, pleated skirt swishing in a zephyr that twisted through the Everfree Forest, so cool her braless nipples poking into her thin blouse. Her little silver crown bounced on her head, a reminder of her status.
Once they reached town she politely excused herself and scurried on home. Father had convinced her not to move out, but unfortunately he was currently away on business, leaving her to dance around her mom. She sneaked through her window, and hid in her locked room, pouring over her latest acquisitions. “Huh, wish I'd paid more attention.”
She had no idea what any of these did. Their contents bubbled under the corked glass bottles. Sitting with her legs crossed, she poked the vials, the colorful contents bubbling away. “Who to use as a guinea pig...? Of course!”
Placing her junk back in her purse, she strolled downstairs, where Spoiled Rich was lazing about on the couch. Draped in a sheer nightgown that constricted to her voluptuous frame, she rested on a bunch of heart-shaped pillows while reading a fashion magazine. “Well, it's about time you came home! Where the heck is dinner? I'm starving!”
“Sorry,” said Tiara with forced sweetness. It wasn't her turn to make a meal, but like always she had to pick up the slack. Only this time she had to suppress an evil chuckle, heading to the kitchen and raiding the fridge and shelves for something quick and tasty. “Bitch,” she mumbled under her breath. “Maybe this'll finally teach her to treat me with the respect I deserve!”
Humming, she shook her plush bottom back-and-forth, mixing in heaping helpings of spices into the stew she prepared. Vegetables were chopped and tossed in willy-nilly, her chaotic creations surprisingly tasty, although of course her mother would quickly stifle the blissful expressions the flavor left on her face and labeled them as merely adequate.
“Ah, there.” Her nostrils flared as she inhaled the scent of her latest self-proclaimed masterpiece.
A shrill voice called, “Is it done already?!”
“Coming!” She picked a couple potions at random, dumping small amounts into a bowl she prepared, hopeful that the taste would cover up and oddities. Her fist tightened around a spoon, mixing it in before she arrived in the living room.
“Finally! I swear, it was less slow and painful giving birth to you!” She snatched up her meal.
“You're welcome.” She started to turn and head back when her tail was snatched and tugged. “Ouch, damn it!”
“It's too hot! You eat this one!” She spun her around, shoving the bowl back at her.
“Uh, no thanks, I'll-”
She bared her teeth. “Now, little lady!”
“You don't get to push me around anymore!” But when her mom started to rise, probably ready to pull down her panties and land another bare-assed spanking on her, she speedily spooned down the meal almost without thinking twice.
“Not fast enough! You know what's coming next, so assume the position!” She patted her lap with a sneer.
Resigned to her fate, Tiara drew down her underwear of her own volition, and draped herself over Spoiled Rich's thighs, her dock raising her tail to expose her plump bottom. Tears wet the corner of her eyes. She reflexively clenched her buttcheeks, trying to mentally prepare herself before hands were laid upon her. Worse still, her tummy was starting to ache.
“It...it hurts,” she mumbled.
“I haven't even started!” Suddenly a whoosh sounded, a palm striking one of Tiara's supple cheeks, making the flesh ripple as a yelp escaped her pouty lips. A red hand print was imprinted on her skin. But this only seemed to spur on Spoiled, who alternated between buttocks, raining down blows that echoed through the house. “Bad girl! I regret the day you were born!”
She whined and cried and rode out her punishment. Her butt was beaten raw like usual, to the point where she'd walk funny for quite a while. Her one solace was Spoiled tended to leave her alone for quite a while after these sessions, until she healed up.
After another round of spanks, her derriere now stained scarlet, Spoiled finally relented and waved her away. Tiara stumbled to her feet and tried to reclaim some of her dignity, her backside aching even worse when she pulled back on her underwear.
Her stomach fluttered even worse, twisting into a knot. She wondered if it was a bad heat coming on, or just simple nausea, but her ears twitched, no doubt that the mixed potions had some sort of bizarre effect on her. Her first instinct was to rush to the bathroom, paranoid thoughts of needing to contact Zecora running through her head. But she couldn't bring herself to do it.
Suddenly, her loins started to boil with an intensity unlike any she'd ever felt. She bit her lower lip, trying to stifle a low moan, as her thighs pressed together and she creamed her panties, a wet spot spreading across the crotch. “F-fuck...”
Spoiled whipped up with balled fists. “What was that, young lady?!”
Anxieties transformed into a rage that burned throughout her entirety, almost like Tiara had been possessed. “I said fuck you!” She stomped towards her mom, who suddenly balked, taking an awkward step backwards. She grabbed Spoiled's arm with a strength that relied her smaller appearance, wrenching it behind her back when she turned her around.
“Y-you'd better unhand me now! If your father finds out-”
“You won't tell him,” warned Tiara darkly. “Not unless you want me to start with that fat ass of yours!” She bent Spoiled over the couch, making her shriek and thrash helplessly in her grip. She laughed at her predicament, for once the one holding all the power! Her panties started to strain, her groin twisting as the flesh morphed, her clit extending and swelling.
Pretty soon a flared and veiny stallionhood poked out and a pair of testicles tumbled below her newborn cock. Precum oozed from the tip. She rested her new equipment between her mother's voluptuous rump, eager to test her tool out.
“Wha-what in the-? N-now wait a moment, please-”
“Oh, you're begging now? You certainly never showed me any mercy!” Baring her teeth like a wild animal, she shredded Spoiled's gown, ripping the silky tatters away and casting them aside. “Bet a wet fish like you doesn't fuck daddy anymore!”
Met with silence other than the occasional sob, Tiara assumed she'd hit home. No wonder Filthy Rich had so many mistresses on the side, his wife once selling herself for easy money but no longer even bothering to put out. He probably kept her around for appearances, and for Tiara's sake, away so often he had no idea how poorly she treated their daughter!
“Hmmm, what should I start with? That tight little asshole?” She spread a cheek and spat upon the pink ring of her rectum. “Nah, looks like you haven't given that pussy some use in quite a while!” With a couple fingers she pried it open, velvety folds spread to reveal the bright glistening tunnel within. “Oh, wet already, huh? No wonder you're such a cunt! You just need to get laid more often! Well, who am I to deny you?” She took aim, teasing the entrance with a brush of her swollen penis.
“Please...agh,” whined Spoiled when she was impaled. Her hanging tits bounced and slapped together when Tiara started to savagely rail her, letting out all the pent up aggression she'd built over a lifetime. Once she'd taken it out on everyone around her, but now Spoiled would be her vent, and she was ready to blow off loads of 'steam' straight into the depths of her core!
She pulled Spoiled's tail, landed slaps on her wobbly rump, and carved her open each time she hammered into her. The moist crevice blossomed out from her girth, leaking trails of clear juices down now matted thighs. She sheathed herself with each brutal thrust, determined to completely fuck her into submission, her heavy balls slapping all the while.
“Bet daddy hasn't screwed you like this in years, has he?! Probably can't stand to listen while you bitch and moan like the stupid whore you are! Maybe next time you'll be a bit nicer, huh?! Well, it's too late!” She shoved a couple fingers into her mouth, both to put her in her place and finally shut the slut up. “Now get sucking! Yeah, that's nice~”
Lewd smacks sounded when Spoiled slurped on the digits, taking them past the knuckle. In the meantime Tiara continued to plow her mother, her dick tingling each time the slimy fissure constricted around her. Despite herself Rich started winking below, reflexively milking her rod which slammed against her cervix entrance. Sniffles mixed with soft coos.
“Do you still regret the day I was born? The way I ruined your perfect figure?” She yanked her tail harder, making her shriek like a shrill banshee. By now her meat was inflamed, barely able to hold back anymore, unused to her new extension.
“Ready to become a mommy again?!”
“D-don't,” begged Spoiled. “Anywhere but inside-!”
“Too late!” With a final brutish slam that rocked their entirety, she buried balls deep, and her eyes rolled into her head when she started to unload. Firehose-like sprays painted Rich's watery womb, striking with such force she came with her, Spoil's eyelashes fluttering rapidly and tongue lolling out when she squirted all over her daughter multiple times.
Tiara's palms cupped her mom's udders so hard she winced, pinching her erect nipples between her thumbs and index fingers. Twisting, tugging, and stroking the pink nubs, she drained the last drops inside her, until Spoiled buckled and Diamond collapsed atop her sweaty back. They huffed and collapsed into a mix puddle of their own juices.
A sliver of sanity started to return when they basked in their afterglow. Tiara questioned what she'd done and why. This wasn't like her, was it? She was supposed to be a nice mare now. So why did it feel so wonderful...?
Spoiled Rich slowly turned her head, dull eyes glazed over. A dopey smile crossed her face. “Give it to me some more...”
