A Tineey Little Sleepover

Everypony was in their night-gown. The dress-code was perfect.

Of course, there were little differences between them, since every filly couldn't simply buy the same thing as the other when they went to the store. The fashions young fillies were getting to these days were practically scandalous by yesterday's standards. Though there was, of course, the odd peculiarity of covering normally nude horses anyway.

Diamond Tiara, the most elegant of the group, or at least the most determined to spend her daddy's money to show she was elegant, had on a fishnet/lace combo of mixed blacks and reds. It had a skirt like frilly bit that bloomed out around her backside and highlighted her petite pink rump and the slightly larger size of her pony-teats when compared to her best friend's. Diamond Tiara could never resist an opportunity to show off, after all.

Silver Spoon, on the other hoof, had opted for a similar motif in fishnet, but a fit that clung much more tightly to her form than Diamond's did to her, and a commitment to the plain black, absent any colour to keep from clashing against her soft, silver coat. Her boobs fit snuggly under another patch of fish-net, with her nipples just poking out from inbetween one of the tiny holes, but her underage slit was the item on full display, the only section of her night-gown 'missing' to show off how wet she already was before the evening had even started.

Tineey's night-gown was something he and Cupcake Sweets had put together, together at the last minute, and despite the pair's previous overall inexperience with fashion, Cupcake was pretty proud of the simplicity of the design, if she did say so herself. It fit Tineey like a glove, at least when he was in his 'apparently filly form', and had little highlights in sparkly white and gold to match Tineey's albino complexion. Finally, a little pink bow atop Tineey's head completed the feminine flair, enough that somepony would surely mistake him for a demure, diminiutive filly from a short distance. Of course, Diamond's parents, the only ponies likely to be interested in that distinction, were already by now out cold, and not likely to be conscious to pose inquiries until the next morning.

Plenty of time for Tineey to be teased, in other words.

Cupcake Sweets hadn't shied away from the opportunity to flaunt her rare penchant for fashion, and so her night-gown was the most colourful of the bunch, a veritable technicolour cotton candy swirl of pinks and greens and purples and all other sorts of shades, blurring somewhere past the visible spectrum as they wrapped around her eye-catching underage curves, showing off especially her big, bulging teats, which hung out of her gown like two show-winning puppies put out on display. Cupcake had caught herself staring at... well... herself, already a few times, and would likely do it again before the night was over.

"Welcome, you two," Diamond Tiara said. She stood in her best impression of a regal pose in the middle of the play-room, smirking knowingly at her guests. The plan, as it followed, wasn't much of a plan of sorts: more of a 'point A, point B', kind of conjecture. Diamond and Silver both knew Tineey's secret, and they knew they were determined to coax it out of him as quickly and with as much sultry flare as possible. After the second time Diamond had described the sheer size of the albino changeling's member to her best friend, Silver Spoon had begun drooling, and went home quickly afterwards to practice with her throat and an old wine bottle from her father's cupboard.

Tineey and Cupcake Sweets could both feel a slight nervous energy in the air, but they handled it very differently.

While Tineey practically curled into himself, tucking his legs together in a pantomime of hiding his prick from view, when in fact it was already well hidden with his disguise. Cupcake, on the other hoof, barged over to the two socialite fillies and wrapped a hoof around each of them, beaming like a business pony who'd just sealed a deal to supply the pony pornography needs of every 'brony' in existence. Whatever they were.

"'Hay' yourselves, you two!" Cupcake said. She giggled and ruffled Diamond and Silver's manes with a hoof on either side. The glares they gave her did little to diminish the enthusiasm of her rubbing.

"I said 'welcome,'" Diamond Tiara corrected with a sigh.

"Yeah, right, whale cum, horse cum, it's all great. Is that what we're gonna do all night: talk about cum?"

Very rarely, on occasions when she'd had too much sugar, Silver Spoon could be exactly like this: a haywire, diet soda version of Pinkie Pie. After her head almost exploding from sheer annoyance the first few times she'd encountered it, Diamond Tiara had learned to let the absurdity of her friend's behaviour wash over her like an ocean wave. Despite the salty taste it left in her mouth afterwards, she could survive without issue every time now, and the analogy remained intact and devilishly layed, like an intricate bean dip.

So Diamond Tiara said nothing. She sighed again, but her frown shifted gradually to a smile, as it often did when her machinations were creeping into place without any real effort on her part. The maid had done her job, and was due to be teased with a flash of filly flank later, when all the party had settled down. It was the party, after all, that was Diamond Tiara's focus. That, and Tineey, who was currently doing a very good job of hiding what Diamond Tiara might as well have referred to as his 'special talent' from now on.

And what best way to get him to reveal it, all shy and sexy in his miniature night-gown? Would it rip apart to shreds when his full size was revealed, or stretch and expand with him, until it was clinging tightly to his skin just the same, but this time with a hulking monster of a cock bulging out from underneath?

"Actually," Silver Spoon said, "we were gonna watch a movie. Infinity Horse. Sound fun?"

Cupcake Sweets nodded fervently. Movies meant popcorn. And sitting down for a while. And blowjobs in movie theaters. Maybe a slumber party could have a version of all of those.

"Yeah!" Cupcake said. She looked to Tineey, smiling, seemingly settling their pre-arrival debate of whether or not the formerly diabolical duo was to be trusted. "A movie sounds awesome. Can't be anything sneaky about that. Right Tineey?"

Despite the fact that he was only one of four ponies, all wearing a night-gown designed to show off their various bits and pieces, Tineey couldn't shake the feeling that he was on display. Even with his monster meat hidden, the sense of balancing your entire body, holding up a delicate egg only with the force of your breath... Tineey couldn't decide if he liked the way it made him feel or not. Tense. Pent-up. Hot.

"Oh," he said. "Right."

"Come on," Diamond Tiara said, gesturing with her foreleg to the big purple-and-pink couch sitting in front of an enormous, wall-sized television screen. "It's a bit small, but there should be room for all four of us if we squeeze in." She gave Tineey a knowing look and smirked, her tongue sticking out between her teeth. "No problem. Right, Twinkle—I mean, Tineey?"

It felt like the air had wiggled just then. He was sure he'd heard his name. No... that name.

But maybe it was just a left-over whisper from yesterday.

"Right," he said, even though he wasn't sure what he was agreeing to.

Moving like an autonomous unit, mostly at Diamond Tiara's direction, the blob-like collective of four foals in various states of sultry night-wear gravitated towards the couch. It was, as mentioned before, not quite suited for the size of four occupants—and Diamond Tiara and Silver Spoon seemed determined to form either end of the smooshy sandwich, with Tineey in the middle, and Cupcake off to one side, like a pickle or radish garnish. Cupcake wasn't particularly put out by the exclusion, since her boobs were still big enough to brush up against her neighbour's: Diamond, in this case.

"This is a great movie," Diamond Tiara said, flicking the screen to life with a press of the remote, bringing the screen instantly to the opening wash of a film. "Just sit back and enjoy."

Tineey did his best to do as directed. It felt especially odd, being suddenly so familiar with two ponies from school who'd barely bothered to say 'hi' on an average day. Now here he was, stuck between the two of them, and feeling even more nervous than usual about keeping his true form under wraps. Whatever the movie was, hopefully it would turn out to be a sufficient and suitable distraction.

The outline of two ponies in the dark, climbing over each other to the sound of panting and muffled moans, however, did not bode well for Tineey in this respect.

"Oops," Diamond Tiara said flatly, barely even bothering to pretend to sound genuine. "I guess I put on the wrong movie. This looks like one from my dad's collection."

Diamond and Silver shared a giggle. Tineey and Cupcake were both fixed forward on the screen, with Cupcake's mouth hanging open just a little as the two ponies and their make-outs came further into focus. Idly, as though she wasn't even aware of it, Cupcake started to squeeze her legs gently together, applying pressure to her little cunny and her bulging teats as well. Between the sandwich of the diabolical duo, Tineey did his best to try not to notice his friend, but failed miserably, torn between the screen and the real-life whimpers mounting in volume beside him.

"Your dad has the best taste in movies," Silver Spoon chimed in. She was sitting on the couch in such a way as to spread her legs out blatantly, showing off the way her night-gown was perfectly fashioned to expose her glistening, underage slit. She put one hoof just above her tiny, pink lips, and rocked herself back and forth slightly, causing Tineey's eyes to lock firmly in place, another destination from them to get lost in looking.

So it was like that. The four of them, squished together on the couch, the on-screen couple rapidly devolving from PG-13 antics into sexual shenanigans best described in detail in the back-room of a video rental store. It was, for all intents and purposes, an atmosphere impossible to be immune to, when it came to the slight fragrance of underage sex in the air, the night-gown pressing into Tineey's skin and making him feel even more like a package that was destined to explode. Each time either Silver or Diamond pressed their flank against his, Tineey felt the lightning shiver of an attempted change tingle down his spine, did his best to suppress it with a noise like swallowing a lump in his throat. Even though it was hidden, Tineey could tell his cock was hard, achingly so, and that the second his diguise let slip, there'd be no more hiding the gigantic piece of meat between his legs for the rest of the night. Tineey wondered if this was what cookie-dough stuffed into a tube might have felt like.

"Ooh, look," Diamond Tiara said, pointing to the screen with one hoof. "She's taking his whole cock down her throat. Do you think you could do that, Cupcake?"

Cupcake's eyes shot wide open, the sudden jolt of her name drawing her out of the on-screen revelry. She took another moment to squeeze out a few last desperate presses of her hind-legs, then did her best to imagine an answer to Diamond's question that didn't put herself too high on a pedestal. Because she knew she could do that, and then some.

"Maybe," she eventually said, turning slightly on the couch and noticing for the first time exactly how tight together her best friend was squeezed with the two rich ponies from class who'd never before given them the time of day. Either something was up, or Tineey had overnight become very popular for no particular reason. "I think if I started small I could work my way up to it. A big cock, I mean."

"Don't you just love big cocks?" Silver Spoon drawled, turning towards Tineey and running a hoof suggestively along one of his hind-legs. "They look so huge and veiny... I just wish I had one to suck on right now."

"Mmm," Diamond Tiara said. "Me too."

"Is it getting hot in here?" Tineey asked, his voice even meeker and squeakier than usual. "It could be just me, but it kinda feels like it's sorta getting hot in here. Maybe we could—"

"Who wants to play truth or dare?" Silver Spoon blurted out, throwing herself sideways onto the couch so she was practically lounging overtop of Tineey in his night-gown, pressing her teats, the smallest in the room but still sizeable, against right where Tineey's cock would have been, were it not properly hidden.

Diamond Tiara giggled and cuddled up to Tineey's other side, running a hoof along his chest, tracing circles through the thin fabric of the clinging night-gown. "Sounds fun," she said. "I'm in. Tineey? What about you?"

"Um, well—"

"Cupcake Sweets, do you want to play too?" Diamond Tiara asked with a quick turn of her head, doing her best to seem as though she was no more rubbing her half-naked body against Tineey's well-restrained form than simply sitting on the couch and waiting for a reply.

And though she couldn't help but feel for her friend, Cupcake Sweets would always be a sucker for truth or dare. Always. You just couldn't find a naughty party game that was more fun. Not even... well, anyway.

"Sure," Cupcake said, smiling and bouncing up and down on her tiny fragment of couch cushion. Her bounces made her boobies shake, and she caught both Silver Spoon and Diamond Tiara staring for a little bit before quickly averting their eyes. She couldn't help but giggle. "I'm in. I love truth or dare."

"Me too," said Diamond Tiara.

"Me three," said Silver Spoon.

"Uh," Tineey said. "Is it okay if I go to the bathroom first?"

"Not yet," Diamond Tiara said. She hopped down from the couch and dragged Tineey, with Silver Spoon on his other side, towards a circle of bean-bag chairs, which she plunked herself down in, Silver Spoon again forming the opposite end of the sandwich.

Cupcake Sweets came over shortly, sighing at the sensation of finally being an unsmooshed capper at the edge of the couch. She could stretch herself out all the way on a beanbag chair, and she did, lounging and extending her hooves and letting out a cute yawn that made her face stretch out too. When she relaxed back into the bean bag, it jiggled a little, the same way her boobs had done. She let out a little 'eep' as one of her nipples brushed against the soft fabric and hidden plastic beans.
