“All right, bottle,” Applejack said sternly. “Pick somethin' good, cause it's your last chance before you go to the recycling.” She flicked her hoof and spun the container.

As it twirled, the neck flashing past all ponies in attendance, every single one of them had a glimmer of hope that it would be them. None of them were satisfied yet, despite the late hour and the many orgasms they'd all enjoyed throughout the night.

The bottle rolled to a stop pointed at the gangly purple creature sitting at the head of the table. Twilight sighed. “Oh damn, I'm not sure I have another round in me just yet.” But her eyes were alight with interest, paying Applejack's nearly-hidden cock extra attention.

“Sure ya are,” Applejack said with an eye roll. “At least you and I haven't gone together yet. Nice to close out the party with something new.” She hefted her die, and Twilight snatched hers up as well.

They rolled together.

Applejack's landed on the messiest side, depicting several gender arrows and crosses in wavy, uneven spiral. She felt the changes right away, and they reminded her of her last transformation, except in reverse. Her chair creaked as she grew larger, heavier. Her muscles and bones burned as they thickened and got stronger. Her face tingled, reshaping itself into a sharper silhouette.

Meanwhile, Twilight's die showed an X. With a hiss of air and a quiet pop, Twilight fell back onto her chair, the tall pony alicorn that they were all used to. She looked down at herself and huffed. “Stupid Discord.”

Berry grinned at Applejack and gestured between them with a hoof. “Same hat!” he shouted.

Applejack looked up at her brow, where she could just barely see the brim of her hat, then back to Berry's bare head. “Uh… what?”

Rainbow giggled—a surprising sound coming from Rainbow under any circumstances, but with a deeper, throatier voice it was doubly strange. “You look like Big Mac!”

“Oh, she's not that big,” Fluttershy corrected. “But she does look… nice.”

Rainbow nodded sagely. “You're right. She's a lot cuter than Mac too.”

Applejack felt herself blush at their comments, and she ground her teeth at her own reaction. “I swear to Celestia, if any of this gets back to him, this will be the last time.”

“We're just poking fun, darling,” said Rarity. “Please, draw a card before the morning light shines any brighter.”

“Hmmph.” Applejack did as she was told, sliding a card off the pile and flipping it over. “Talk as dirty as we can and make everypony else red.” Just desserts, she thought.

Twilight smiled. “Oooh, that sounds fun.” She bit her lip. “Maybe kind of an anti-climax… but fun.”

Applejack shook her head, a wry smile on her face. “Ain't y'all had enough climaxes for one night?”

“Under normal circumstances, yes. Maybe too many,” Twilight replied. “But you can't honestly tell me that you wouldn't like another turn with every single pony here.”

“I could take or leave Berry. Sorry, sugarcube. The wiener I could overlook, maybe even the rest of the stallion-y body, but the whole package? Y'all might go both ways, but I'm still nice and comfy on my side of the fence.”

The pink pony nodded in understanding.

Rarity laughed. “What a careful way of avoiding the question. Fine, perhaps you can resist Berry's masculine charms, but what about we four mares, hmm?”

Applejack tried to keep a stone face. She raised her signature eyebrow and gave them all her best bored stare.

The room erupted in giggles.

“Hey, boss,” Rainbow said between laughs. “Your eyebrow isn't the only thing that's… cocked!”

Applejack looked down and sure enough, she was almost completely erect again, the tip poking out from between her thighs to say hello to the room. She could also see that along with her thicker, more rugged body, her shaft had grown in kind. No longer a cute, barely-average endowment, its length and girth now rivaled the equipment she'd spied hanging underneath the hardiest earth pony farmers. And she would never admit it, but over the years she'd seen enough of her brother to know his rough dimensions, and this new body of hers stacked up fairly well in comparison.

To her brother's cock.

Rainbow Dash must have noticed the sour expression on Applejack's face. “What's the matter? Not such a fan of it now?” Her voice was teasing, but her eyes were soft and sympathetic.

She shrugged off any thoughts of family and shook her head. “Nah, just tired I suppose. From all I've heard, stallions aren't really built for ten hour long sex parties like this. Aren't these thingies supposed to pop once or twice and then hit the hay?” She jiggled her member with a hoof to illustrate her point.

“It depends,” said Berry. “Most of the time a few orgasms are all ponies want, but if you take the time to recharge, you can keep spurting all night long!”

“Illuminating,” Rarity said dryly. “Twilight, Applejack, have you started your challenge yet? I suppose there are less titillating topics of conversation, but by the standards we've established tonight this is rather tame.”

“Right, right.” Applejack cast her eyes around the room, selecting her target. “Fluttershy… uh… seen enough vag tonight to last a lifetime, huh?”

“Ugh,” Rarity said. “Vag? Clearly somepony has never exchanged flirtations in her entire life.”

The yellow pony blushed. “Oh, um, no, I don't mind at all. Even though I don't like… mare bits… as much as I like…” Her blush brightened, and her eyes started to drift down Applejack's body before she corrected herself. “Um, anyway, it's still nice to see all of you like this. It feels like we're a little bit closer now.”

Applejack bit her lip, then smiled. “I bet you'd like to get even closer with me. Or maybe Berry? I saw how you were lookin' at Pinkie Pie when I was filling her up earlier.”

Fluttershy shifted on her seat, forehooves pulling in tight against her torso, no doubt pressing against her damp, tingling lips. “M-maybe next time.”

Twilight jumped in. “Next time, if the game lets you do that, right? There's been a suspicious pattern to everything tonight.” She narrowed her eyes. “I almost get the impression that Discord doesn't want anypony here to slide their hot, hard shafts into you.”

“Eep!”

“You think he's jealous?” Applejack said. “Or does he just want to make Fluttershy desperate enough to jump on somepony whether the cards tell you to or not? Downright rude of him either way. If he'd done something like that to the rest of us, that'd be one thing. We'd just hop to and get 'er done.”

“Big talk from you, Applejack. I've seen you eye-fucking Rainbow Dash all night.” Twilight nearly stumbled over the swear—something she'd heard Rainbow Dash say once before. “Any reason you haven't 'gotten her done?'”

Rainbow rustled her wings and adjusted her hindlegs as her cock hardened. A croaky voice asked, “Y-yeah, AJ. If you want some Wonderbolt action all you've gotta do is ask.” Then she looked down at herself and visibly wilted. “I mean, uh, when I'm normal again. I know you're not really into dicks.”

Applejack opened her mouth to object, but took a moment to look at the huddled bundle of feathers to make sure she meant was she was about to say. She'd never really thought about griffons that way before, let alone male griffons, but the thought of Rainbow Dash splayed out underneath her, wings framing her on either side, her flanks and tailhole and… and cock all exposed to her…

“Sugarcube, I'd go for a roll in the hay with you any time.” Then she remembered her own transformation. Applejack dropped her forelegs onto the table and raised herself up, emphasizing her broad shoulders and muscular legs—a physique that managed to even dwarf her own natural farm-toughed exterior. “And I don't reckon I'd have any trouble keeping you in line right now, neither.”

“Oh please,” Rarity said teasingly. “Fluttershy is supposed to be the timid one, but you two have been balking away from each other all night.”

“Sounds like Rainbow Dash to me,” Twilight jumped in. “She can rub one out in the middle of a party like it's nothing, but honestly admitting her feelings is terrifying.”

Rainbow threw up her hands in exasperation. “I'm not going to take that from two ponies who've been chasing each others tails without even realizing it for years. AJ and I used to be at each others throats almost as much as her and Rarity, but you two have been acting like marefriends since day one, so what's your excuse?”

“We have not!” Twilight countered. “I love all of you! Rarity and I just happen to share more interests in common.”

Rarity nodded. “Just so, darling. And while I certainly wouldn't object to a spot of romance…” she shook herself “Ahem, with any one of you… Twilight and I are merely confidants.”

Twilight could feel herself sweat. She was grateful she wasn't human anymore, otherwise she had a feeling everypony in the room would have noticed immediately. “Hey, Rarity?”

“Y-yes?” Rarity said, turning to her with a nervous expression. Perhaps her mind was racing as quickly as Twilight's.

“Now that you mention it, I… I've been thinking that it would be nice to have a partner now. With everything happening, the royal politics and the school and everypony growing up and getting older… And you and I do spend a lot of time together already.”

Rarity's lips pursed as if she needed to think it over. Her mind raced for rationalizations. “I suppose that if I had to choose somepony to be at my side during fashion shows, or business meetings, or simply to enjoy a lavish meal at a Canterlot restaurant… I could hardly find a better suitor than you.”

Rainbow snorted. “I can't believe that after eight hours of nonstop sex between a bunch of mares, that's the gayest thing that's happened tonight.”

“How uncouth.” Rarity said, but the corners of her mouth quivered as she suppressed a grin.

Twilight beamed. “She's not wrong though.”

Applejack smirked. “Well, does everypony feel plenty embarrassed? Oh, uh, I guess we haven't said anything about Berry yet. You, er… I guess you got everything you wanted tonight, huh?”

“Not eeeeeevery thing,” he said cheerfully. His eyes swung over the Fluttershy. “But don't worry! We'll all get there soon!”

“Get there?” Applejack asked, puzzled.

“Just wait and see.”

While the room puzzled that one over, a distant rooster crowed.

Twilight took that as a sign that the night had officially ended. With her trusty levitation magic, she gathered the dice and the deck and placed them back into the box, then lowered the lid on top.

It felt like several invisible, hair-thin cords were severed as the box was shut.

Rainbow Dash shuddered and yelped as her talons disappeared and melted into hooves, and her feathered plumage flattened out into a uniform blue coat. Rarity gasped as green fire flicked across her form, leaving her unchanged as whatever facsimile of changeling magic dissipated from within.

Twilight looked around at the sudden dramatics. “I guess the box has some anti-chaos enchantments built into it. That… that I might need to study later.”

“Uh, Twilight?” Rainbow Dash said, her voice soundly slightly panicked. “If we changed back into ponies, why do I still have a penis?”

Across the room, Berry piped up. “Oh yeah! Weird.”

“What in tarnation is going on?” Applejack's deep, rustic voice called out.

Twilight blinked. She was stumped. It seemed that the night still wasn't quite over.
