Pinketosis

“Saturday morning! I’m gonna see Cheese!” Pinkie sang happily as she twirled Gummy around her bedroom. “He’ll say ‘Sex?’ and I’ll say ‘Yes, please!’ With a wrinkle of the ear and a twitch of the tail, my Pinkie Sense says I’m about to get nailed~!”

Gummy yawned. The excited earth pony set down her pet, tossed back a gulp from the Chalice of Life and enthusiastically began her exercises as the magical cup quickly refilled with the fruits of dozens of stallions’ morning clop sessions. She moved her bounteous and bouncy body through the dildo squats, the tushie plug — and lots and lots of bondage stretches, of course! Pinkie wanted to be extra flexible today for her oh-so-stiff Cheese Sandwich!

Pinkie still couldn’t bear to look at her scale, but weight was just a number, after all. The only thing that mattered was fitting Equestria’s sexiest mare into Equestria’s sexiest dress, and on Saturday morning, after a week of tough dieting, she finally made it inside.

She held her tummy in as far as she could. Mrs. Cake held the zipper firmly in her teeth and was finally able to pull it up that final notch. Pinkie adored herself in the mirror as the older mare used gel to style her puffy mane into ringlets. The once shy rock farm girl was now a perfect ten! Maybe even a twenty!

The final touch was a light application from Pinkie’s very own tube of bright red slut lipstick. She blushed to think of what she’d done to earn the lipstick, but she knew it would all work out. Cheese was going to love every naughty trick the Cakes had taught her in the past week!

Mrs. Cake smiled and looked Pinkie over possessively. “Now get out there, before I rip that dress off and fuck you myself!” Pinkie giggled and squeezed through the door to Sugarcube Corner. She was finally ready for her reunion with her cute, funny, hunky coltfriend!

The straps of the dress bit painfully into Pinkie’s withers as she carefully walked through Ponyville towards the train station. Her hooves wobbled in her high heel horseshoes, and the jumbo plot atop her long legs waggled back and forth in perfect time, straining at its confines. Her plentiful thigh meat bulged out and over her fancy stockings, creating a nearly unbearable friction as two pairs of muffin tops rubbed together with every step. Mrs. Cake’s mane gel smelled weird and made Pinkie feel like she was about to sneeze. She was super duper uncomfortable, but it would all be worth it to hear that “boing” as her stud’s erection shot out of its sheath, ready to claim the slim and sexy Pinkie Pie!

If the stallions of Ponyville were anything to go by, Cheese wouldn’t stay sheathed for long! Pinkie turned heads and gathered low whistles as she slowly stepped through the town plaza, trying desperately to stay inside the dress long enough for Cheese to take it off of her. Even Hayseed Turnip Truck, Rarity’s ex from high school, turned away from the window he was washing and ponycalled her.

“Wow, Pinkie! Yer lookin’ fine, mama! C’mon, sit that thing down on mah face so I can tongue punch yer fart box!”

“That’s not an appropriate thing to say, but I appreciate the thought!” Pinkie scolded. She couldn’t understand what her fashionable friend had seen in the crass, low class pony... which meant he must have a truly enormous dick. Gosh, Rarity was such a size queen! Pinkie didn’t get it. Cheese wasn’t the biggest guy around, but he was definitely the bestest in beddest!

At long last the train from Yakyakistan pulled in, and Pinkie’s excited legs quivered in their stockings. She was ready for anything: slut lipstick on her lips, perfume behind the ears, a creamy lube dabbed into her scrumptiously clean ponut, and enough au naturale juices flowing down her thighs to float a small yacht. Surely Cheese would want her to demonstrate her well honed blowjob skills on him... maybe he’d even picked up a new kink or two in Yakyakistan! Pinkie was determined to deny her coltfriend nothing, and when Cheese finally launched his first volley of spunk into her it would be the ultimate dessert to end her painful week of dieting.

Creatures of all races got off of the train as Pinkie bobbed her head, trying to catch the first glimpse of her coltfriend. Finally she saw him helping carry an elderly yak’s suitcases towards the station. What a sweetheart! There was the curly mane and the handsome smile Pinkie loved! Instead of his trademark tropical shirt, though, Cheese was wearing a novelty Yakyakistan tee that said YES FAT CHICKS!

Pinkie ran up to her beloved, flung her hooves around his neck and kissed him, sending her tongue plunging into his mouth and smearing slut lipstick all over his muzzle. “Cheese, I missed your dong so much!” she squeaked. “Oh, and the rest of you, too!”

“Wow, Pinkie!” Cheese was overwhelmed by the force of Pinkie’s passionate kiss. “What a welcome! Step back and let me take a look at you!”

“What do you think? Do ya like my dress~?” Pinkie backed a few steps away from her coltfriend and posed coyly. Behind her, the fabric of the dress creaked ominously as her clearly outlined clit pressed against it in a wink.

“Pinkie, I... wow, wow, WOW! Would you do a little turn for me?”

“Oh, erm, all right, but don’t look at my plot, please?”

“But I want to look at your plot, Pinkie,” Cheese Sandwich panted. “I’ve been dreaming about your plot for a month! There’s nothing in all of Equestria I’d rather look at!”

Pinkie bit her lip. He was so sweet and enthusiastic, she couldn’t say no! “Alright, but be nice, will you? My butt’s had a tough week.”

Pinkie sweated and quivered as she slowly rotated in place, her ass coming into Cheese’s view like the sun rising, enormous and hot, over the Dragonlands. After all her work, this was the moment — what would Cheese think?

“Aah—”

Grr, why was her nose doing that ominous twitcha-twitch? She’d tried to slim down her Pinkie Plot, really, she had! Hadn’t Rainbow Dash told her Cheese would accept her body as it was? Maybe it wouldn’t be so bad...

“Aah—aah—aah—”

But it was so bad! Just as her massive ass pointed like a cannon directly at Cheese Sandwich’s drooling muzzle, the itchy mane gel got to Pinkie’s nose... and Pinkie sneezed.

“AaahCHOO!”

A Pinkie Pie sneeze was nothing to sneeze at! The sound seemed to echo all throughout Equestria. The force of the sneeze rocketed Pinkie off the ground, sending her legs flying out in every direction. For the briefest of moments it seemed like everything would be OK... and then Pinkie heard the RRRIP.

The dress ripped right down a seam and Pinkie’s ass exploded outward through the fabric, seeking freedom. Somewhere in the distance, Pinkie heard Rarity’s scream of horror. The two irrepressible globes of rump flew off in opposite directions, then wobbled in place and, just as Pinkie’s hooves landed back on solid ground, slammed back together like powerful hoofball players meeting on the field.

Sadly, when the two titans of thiccness clashed, Cheese’s head was right there in between. A noise like a tormented accordion sounded as the unfortunate stallion was relentlessly squashed between two fearless, world-saving butt cheeks. Poor guy! Not since that last fight with Sombra had anypony taken the full force of Pinkie’s meaty bum right to the face — and Sombra was a big meanie who deserved to get slapped with a butt and sat on! Even if he had started to enjoy it, near the end...

For a moment Pinkie’s cheeks pressed so closely against Cheese’s muzzle it was as if she actually saw him with her ass. She felt his heart melting grin distort into a grotesque smirk, his nostrils flaring wide as the bittersweet scent of musk and sweat poured in, his curly mane flattened between prominent planks of perspiring Pinkie pudge.

Finally Pinkie’s ass bounced back again, releasing Cheese from his humid prison. The surprised stallion gasped loudly for breath, almost unconscious. Pinkie fell forward onto her tummy, hardly noticing as her ruined dress split down the middle. This was the most humiliating experience of her life! For the first time ever, her Pinkie Sense was wrong! She wasn’t about to get nailed, she was about to get Cheese-broken-up-with! She pounded her hooves against the train platform and sobbed pathetically.

“I just wanted to be pretty for you!” Pinkie bawled. “It was so hard, Cheese! So many treats I didn’t eat, and it was all for nothing! I’m nothing but a fat ugly mare with an ugly fat ass!”

Pinkie’s body heaved as she cried, her cheeks clapping together loudly like sarcastic applause. Suddenly an odd sound from behind her made her stop and catch her breath. Cheese Sandwich was... laughing!

“Oh, Pinkie, I knew you were the one for me! You’re beautiful, and creative, and hilarious!”

“Huh? I am?” Pinkie queried with a quivering voice.

“The breakaway dress! It’s a timeless prank, but you’ve made it fresh. Hot diggety damn, just lookit dat plot!”

Then Pinkie heard it: the “boing” of Cheese’s erection. The biggest, firmest “boing” she’d ever heard! She dared to take a glimpse behind her. Cheese’s mane was soaked with Pinkie’s crack sweat, his shirt was wrinkled and soggy, but his proud Pinkie pleaser bounced between his forelegs, dripping with a month’s worth of pent up precum!

“Y-you like my plot like this?” Pinkie whimpered.

“It’s the most amazing thing I’ve ever seen, and I’ve seen Princess Luna sit on a whoopee cushion!” Cheese cried out. “Jeepers, what else happened while I was in Yakyakistan?”

“I sucked off every guy in town,” Pinkie confessed.

Cheese Sandwich forced a weak smile and his cock drooped with a sad, drawn out trombone sound. “I-I’m sure you had a good reason, though. Right? Maybe a... friendship curse?”

Pinkie blushed and struggled to change the subject. “I eat pussy now, too.”

Cheese’s forced smile swiftly shifted into the real deal, and with a second “boing” the proof of his arousal achieved an incredible new length and thickness. “Aww, you didn’t have to do that! You made your plot bigger for me and you fulfilled my #1 fantasy? What a marefriend!”

“I couldn’t help it!” Pinkie wailed. “Vinyl turned me into a hot bi babe. I know it’s wrong.”

“Wrong? It’s hawt!”

“Yeah, it’s that too. Oh, and the Cakes said we can swing with them if we want to.”

“Mrs. Cake wants to swing? Damn, I’ve died and gone to curve heaven!” Cheese Sandwich reared up on his hind legs and planted his front hooves on his marefriend’s massive ass, paying no attention the crowd that had gathered to stare at the two reunited lovers on the train platform. “Brace yourself, Pinkie!” he called out, his hooves sinking deeper and deeper with every moment into bounteous pink flesh. “I‘m goin’ in!”

“And that’s how you were made!” Pinkie concluded cheerfully. “Actually, that time he stuffed it up my pooper, but the time right after that, we made you!”

Cheese Pie pushed away his dinner plate, vowing to never eat again. “Mom, why did you tell me all that?” he complained. “I only asked you why you’re always drinking from that fancy cup!”

“Because it’s full of stallion cum, and I can’t get enough!” Pinkie told her 18-year-old son. “I thought I explained that! Yepperoony, I’m down to a sensible three cupcakes a day, thanks to the Chalice of Life diet system!”

Cheese Pie squeezed his head between his front hooves. One simple question had triggered a flood of agonizing imagery that no amount of mind bleach could ever erase. “Even if you thought that was OK to tell me, why’d you tell me all the other stuff?” the young stallion moaned. “What’s the point of making me think about you eating Auntie Cake’s pussy, or Dad stuffing your butt, or Princess Twilight getting screwed by that professor in the throne room?”

Pinkie wrinkled her muzzle in thought. “Huh? He was screwing her?”

“Yeah, mom, obviously!”

“The point is...” Pinkie Pie stuck her dinner fork into her messy mane and put a hoof to her chin. “The point... geeze, that’s a real brain tickler, bud! What was the point?”

Cheese Sandwich looked up from his newspaper and came to his wife’s rescue. “The point is, you’ve got to eat right and stay healthy to be a stud like your dad. A sense of humour and plenty of zinc tablets — that’s the key to keeping a mate! Hey, did I ever tell you about my prom night? Why, I bagged two unicorn hotties with my patented hoof buzzer! You wouldn’t believe where they wanted me to put that thing...”

“Wait! I remember!” Pinkie declared, thankfully interrupting yet another obscene flashback. “The point is you should never masturbate, cause your cum might end up in Mama Pinkie’s protein shake!” She lifted the Chalice of Life and swirled around the growing puddle of sperm with a greedy eye. “This one’s safe, though — you’ve been right here at the dinner table this whole time!” Pinkie opened her maw and guzzled a mouthful of sweet smelling stallion spunk. She wiped her lips with a smile. “Mmm, I’m so glad Twilight passed that pineapple juice law!”

“Mom, that’s disgusting!”

Ponyville’s top MILF stared at her son with a look of firm disapproval. “Well, mister, if you don’t like how your mum stays slim, you’d better get out of the house once in a while! Find yourself a mare or a stallion, and get off in a real hole! You know, the Wonderbolts are off on tour, and I bet Auntie Applejack’s feeling mighty lonely tonight. I’m sure she’d love to have a stallion around to help her with the ‘chores...’”

Cheese Sandwich pushed back his chair and slapped Pinkie hard on the ass. Earthquakes rippled through the mature mare’s jiggling plot cheeks, the two biggest reasons why Cheese Pie could never have friends over. The son of Equestria’s biggest pranksters shrank down into his seat as he heard the most dreaded sound of all: his mother letting rip with a wet and squishy wink.

“And don’t hurry back!” Cheese Sandwich told his son. “I’ve got a date with the hottest ass in Equestria!”

“Oh, you!” Pinkie blushed and playfully batted away her husband’s possessive hoof, even as Cheese Pie slid beneath the dinner table, locked in a full body cringe, never to be seen again....
