When a classified ad appears paying 600 bits for medical test subjects, a skint Grey jumps at the opportunity. Unfortunately for him, this non-invasive procedure might take a lot longer than he expected.

Contains force feeding, extreme weight gain and some very, very mild bondage.

My first pony-specific weight gain story, originally written back in 2013 when Grey was my primary fat horse character and this title was probably slightly more original.

Werewolves are terrifying beasts, killers of ponies and cursed beings. Twilight now suffers this same curse, but it isn't as terrible as she thought.

Contains Transformation and Weight gain.

Daring Do. Adventurer, archaeologist, scholar, philanthropist, and all around heroine to the ponies of Equestria. She's faced countless threats and challenges in her years traveling the world, and her efforts have earned her rewards, accolades, and prestige. However, she now finds herself against a new foe, one foul and sinister, so evil and diabolical that even she is powerless to fight against it.

Forced time off.

Banished by her superiors at Canterlot University to the dreary, ho-hum city of Prodigal Point, Daring Do is forced to find a way to cope with deal with her increasing boredom and insatiable curiosity. However, her attempts cause her to stumble upon a mysterious conspiracy, one being carried out by an enigmatic group of ponies with unknown motives. She's soon smack-dab in the middle of the action yet again, and while she's used to such things, she also winds up with a bigger problem that's completely new to her:
motherhood.

[NOTE] Please do not downvote the fanfic solely based on the fat fetish. If this is not your interest, do not read!
Rainbow Dash has become enticed by Pinkie Pie's recent behaviour - backing into her basement for hours, emerging with an even flabbier stomach every time. She finds herself staring in awe, intrigued by her new attraction to Pinkie.
Out of uncontrolled temptation, Dash creeps down to Sugarcube Corner at night, before being greeted by the beautiful bulging pink pony. Pinkie drags her, strapping her into her gluttonous fate.
Ultimately, from cupcakes to gateaux, cheesecakes to cheese pastries, Dash is forced to overindulge until the dessert store is deserted. Pinkie then washes it all down with a calorific milkshake, washing Dash's flying career away in the process. But Dash, finding her new enjoyment in the fetish, submits with satisfaction to Pinkie's plans...

A fic done for B_25's anthology. The whole is done as a birthday celebration for the excellent artist NCMares. I personally adore his art, and was happy to do a fic based on one of his pictures (though I'm by no means a macro expert).

Twilight and the girls are preparing to do a little cheerleading routine for the School of Friendship's hoofball team. It was a challenge that she'd made to the bunch of jocks to motivate them to achieve excellence in their academic studies.

They pulled it off.

And now that they had, our beloved mane six mares are sitting in the tunnel before the halftime show, getting ready to execute the most motivational routine of all time!

But Twilight has a spell prepped and ready to steal the show from Rainbow Dash... will everything go to plan?

Does not contain any sex - but does contain some description of lewd outlines in clothing.

Apple Bloom can't sleep. Surely a midnight snack will fix that problem. But what starts out as a midnight snack soon turns into a midnight feast of pies, apple fritters, and cider.

Takes place during "Somepony to Watch Over Me."

WARNING: This story contains stuffing/weight gain. Do not read if this isn't your cup of tea. If it is, enjoy!

Cider season is right around the corner, and Applejack is ready. As it turns out, so is Rainbow Dash, but for a drinking contest to see who can drink the most cider in town.

Includes: Liquid inflation, some inebriation, a hint of Appledash

Written as a Secret Santa for a Discord server. Hope you enjoy! Happy Hearth's Warming!

Redbow Rose is your average journalist, happily married and perfectly fit. When a spell misfires and hits her, one of these things will change drastically.

Contains: Overnight weight gain, stuffing, and a loving fat lesbian marriage.

Sex tag for fetish content. Alternate universe for changes from the normal show.

Princess Celestia wakes up after a particularly delicious Hearth's Warming to find she's gained a bit of weight, and decides it's time to diet in time for spring.

Princess Luna, however, sees the opportunity for a bit of harmless fun at her sister's expense...

Another oldie, and since the last one I uploaded was some moonbutt, how about some sunbutt?

Sunflower Showers is a new pegasus in Canterlot who has befriended the extremely wealthy son of a quill and sofa magnate and is taken to a mysterious restaurant. The dinner is absolutely delicious and high class, but the "dessert" takes on a role reversal that has Sunflower on edge.

Orchid isn't mine, she belongs to some anon on /mlp/ who has surprisingly little digital presence to credit.

Warnings: Vore, big pony (skip to Dessert if you just want the fun stuff without an infodump.)
