Sunset has a secret. A secret she's kept since the first day she stepped through that portal into the EQG universe. When Pinkie Pie invites her to a special slumber party and claims that the pair will be learning more about each other, Sunset is nervous. What if her secret gets out?

As the party gets under way, it becomes apparent that Pinkie knows about Sunset's secret and she certainly doesn't mind. Can Sunset last the night without giving in to Pinkie's allure?

No. Probably not.

Party of Two

At the end of the school day, the students of Canterlot High raced down the stone steps at the entrance. Each one just as eager as the next one to get home and unwind after their extensive lessons. All but two students that was, Sunset Shimmer and Pinkie Pie. The pair had just come from their final lesson of the term, leaving them free to take their time. Unlike other students, who’d find themselves back at school the next day for their final lessons. It was one of those moments where a lesser being would have gloated to their cohorts about being free from school. Not Pinkie or Sunset though, they had other things on their mind. Namely the slumber party they’d be partaking in later on that very night. Ordinarily, Pinkie would have invited the rest of their friends to enjoy the party, but they were one of the few still taking classes. Pinkie didn’t mind, ultimately she was just happy to be throwing a party, it didn’t really matter if there was only one other participant. It was the experience that mattered after all.

“I’m really grateful for being invited to this slumber party, Pinkie,” Sunset stated, putting her arm around her friend.

“Oh you don’t need to be grateful, we’re friends! Friends invite other friends to parties all the time! Plus, if I didn’t invite you then I’d have to host the party all by myself!” Pinkie replied, throwing her arms around Sunset in a classic Pinkie hug.

“Well, if there was ever anyone capable of throwing a successful party for one, I believe it’d be you.”

“Well…maybe! I’d prefer throw parties for other people though, it’s way more fun than celebrating alone!”

Sunset laughed and patted Pinkie’s shoulder. “True, true. Say, just what are we celebrating with this slumber party anyway?”

“We’re celebrating getting to know each other better! We’ve never really had much time together outside of our little group, y’know? So what better way is there to get all our little secrets out in the open, if not a slumber party?”

Sunset paused before replying, that little tidbit about spilling secrets throwing her for a loop. “Yeah, I guess that’s right…”

“This is me! I’ll see you at seven, don’t be late!”

They reached the start of the pavement where the two would part ways. Sunset’s apartment was much further into the city than Pinkie’s home, which was only a short way from the school. The pair gave each other a wave, and Sunset promised not to be late. As she turned away from Pinkie, Sunset’s mind instantly turned to planning for the night ahead. She had no problem with spilling her own secrets to her friends, especially when she could just tell them all about Equestria. But there was one secret that she struggled to keep on a regular basis. Ever since she’d first arrived through that portal, she’d been granted a stallionhood. At first she believed it to be some sort of curse or spell that Celestia had placed upon her as punishment for leaving Equestria behind. But as the days wore on and they eventually turned into years, Sunset came to believe it was the subject of something else. It seemed a little more like a mistake of coming through the portal, especially considering she never possessed the dick in her pony form. She’d meant to ask Twilight on her next visit if the same thing had happened to her. Though with this world’s Twilight now a part of their group, Sunset had instead just tried to live with it. She’d taken to wearing baggy clothing to hide the bulge it created between her thighs. When she was forced to wear skirts and dresses she chose the longest variants, combined with chokers on her thighs to hold everything in place. Her time at Canterlot High would be more than over if anyone found out she was sporting a horse phallus between her legs. Her mind turned to Pinkie Pie and the last time Sunset had gone to one of her sleepovers.

Twice had Sunset’s secret nearly been revealed during those parties. The first had come when Sunset and Pinkie had been chatting while Pinkie prepared party food. Home-cooked party sausage rolls were the order of the day. Sunset had been sitting on the counter, keeping her legs as straight as possible to avoid bulging. It just so happened that Sunset was sat right by Pinkie’s prep board, where sausages and pastry sat waiting to be merged. Pinkie was too busy chatting about possible extras to go with the sausage rolls. She didn’t notice where her hands were going until she reached out and accidentally the thick tube of meat cradled between Sunset’s thighs. She gasped and loudly exclaimed ‘whoops’ before Sunset launched into damage control about what people would think if she was caught rubbing Sunset’s thighs. Pinkie had seemed to go along with it, even reciting Sunset’s use of thighs in response. After that, Sunset had been a little more careful in terms of just how close she got to her friends. Even when putting her arm around Pinkie previously, she had been careful to point her lower half away, even if it did make her walk rather awkwardly.

The other time that Sunset had almost been caught out, happened with a lot more of her friends. The group had been playing together in Pinkie’s bedroom, taking part in a good old game of Truth or Dare. The evening had been going swimmingly until a particular dare, in which Rainbow Dash was challenged to whack Twilight with a pillow when she would least expect it. Rainbow Dash initially refused on account of Twilight now being aware of the dare and what it entailed. However, later on Rainbow Dash reneged on her refusal, launching a pillow Twilight’s way while she was working her way through a book. She missed by quite an impressive distance, hitting Applejack instead and resulting in retaliation. From there things spiraled out of control with each of the girls joining in. Sunset got so involved in the antics that she failed to notice the choker that restrained her shaft had broken. That mass of meat attached to her crotch swung around like a club, thwacking against the legs of her friends. None of them spoke up about that exactly, but both Applejack and Rainbow Dash made comments about getting hit below the belt. It was only then that Sunset realised what had happened. She quickly withdrew from the pillow fight and disguised it as a trip to the toilet. There she used a few bits of dental floss to restrain her shaft once more, before returning to the bedroom to sit quietly.

All the way home, both of those events played in Sunset’s mind. Part of her wanted to let her friends in on the secret, to at least get it off her chest. She had no idea how her friends would react to the news. She knew it wouldn’t change how they acted towards her, but she couldn’t be sure what they’d be thinking underneath the surface. She continued to think about it as she packed her bag for the evening. Once that was done she picked up a set of clean clothes, exactly the same as the ones she was already wearing. The only difference was that her clean jacket had pointier studs than the one she was wearing. She headed upstairs for a shower before changing into her clothes, then it’d be off to Pinkie Pie’s to start the sleepover.

****

A couple of hours later and Sunset was sitting alone in Pinkie’s bedroom. Pinkie and Sunset had barely spoken since Sunset had arrived, outside of the usual pleasantries. Pinkie had been busy preparing the snacks for the two to share and Sunset had stayed well away from the kitchen. She didn’t need a repeat of last time. So while Pinkie had been baking and cooking, Sunset took the opportunity to unpack her bag and change into her pyjamas to avoid taking a risk later on. To her horror, she found that while separating out the risky clothes from the safe ones, she’d mixed up her pyjamas. The pair she had packed where tighter and shaped to fit her body better, also better at showing off her bulge. She cursed her mistake under her breath, but she was going to have to change into them at some point. Better she knew about it now rather than finding out about it much later. She closed the door to Pinkie’s bedroom and began to strip off. She started first of all with her skirt, wanting to get the worst offender over and done with. At least if Pinkie walked in on her while Sunset was changing shirts then she could live that down more than Pinkie seeing her dick. She shimmied her orange skirt down her legs and onto the floor, stepping out of it and into the legs of her pyjama trousers. Her stallionhood hung soft against her thigh, a little ways above her knee. Oh how grateful she was that it only got bigger when she was hard. She wouldn’t be able to go out in public if it hung any lower when soft. Bending over, shifting her legs to allow the tremendous, orange orbs between her legs to rest easier, she picked up the trousers. She’d lifted them mere inches before she heard a voice behind her.

“Ooooo, Sunset, I didn’t expect you to be so forward!”

Sunset pulled her trousers up fast, yanking them as they got stuck time and time again. “P-Pinkie?! I-I-”

“You? Didn’t hear me come in? Didn’t expect to see me here?” Pinkie giggled. “I live here, silly! Of course, I’d be here! But if we’re playing a game like that, then I didn’t expect you to be so hung!”

“Pinkie!” Sunset gasped, spinning around now that she’d finally gotten her trousers pulled up. Her shaft bobbed obscenely bouncing from thigh to thigh before settling down. “I-wha-I-”

“Oh, relax, Shimmy! I’ve known about your little secret for ages! I just didn’t expect to be so impressed!”

“Ages? You mean since-”

“Before our little ‘incident’ at the slumber party, yep! I’m sure you tried your best, but you aren’t really as observant as you think. There’s been like a bazillion times when I’ve seen this thing bobbing around under your skirt! Or there was that time during gym glass when-”

Sunset held up her hands. “Ok, ok, where are you going with this? What do you want from me?”

Pinkie looked taken aback by the statement. “Want something? I don’t want anything, just for my friend to have fun! It’s the whole reason I invited you and nobody else to this party!”

“You invited me here…to have fun?” Classic Pinkie Pie. “Well, if I’m honest, I don’t feel like I’m having fun. I feel embarrassed more than anything.”

“Oh…?” Pinkie’s hair began to deflate ever so slightly. “Well, I think I can help with that!”

Before Sunset could get another word out, Pinkie leapt over to Sunset and knocked her to the ground. The weight of the plump, party planner forced the air from Sunset’s lungs as she was trapped beneath her friend. Pinkie leaned in close and breathed out softly against her neck, sending a chill down her spine. Sunset gasped, arching her back softly as Pinkie began to kiss softly against her neck. It felt so wrong, but her nethers began to burn with the sensations of lust. She wanted things to progress almost as much as Pinkie. Raising her hands, she caressed the soft, velvet, fabric of Pinkie’s lacy undergarments. The sheer material often became wedged into the soft folds of Pinkie’s body as Sunset pressed her fingers into it. Her breathing came in soft, ragged, pants as Pinkie continued her assault. Pinkie’s mouth moved from Sunset’s neck to her mouth, locking lips between them. Pinkie moaned together with Sunset, as the bulge between the latter’s legs began to grow longer and thicker. The heat from it began to draw Pinkie’s eyes downward and Sunset had noticed. Her own eyes tried not to look down at the swelling mass between Pinkie’s thighs, but even she couldn’t avoid it. This was something she’d thought about since arriving here, albeit in the back of her mind, but she’d definitely thought of it. To use this monstrous shaft that she’d been granted, on someone who wouldn’t judge her, that was it. She wasn’t in control of the situation though, Pinkie was. As Sunset looked up at her friend, she saw those eyes burning with an unnatural lust. Pinkie’s face pushed against Sunset’s, her tongue breaking through and into Sunset’s throat. There was a slight pause as she adjusted, but she welcomed Pinkie’s intrusion. The pair swapped copious amounts of saliva, moaning and groaning into each other as they tried to one up the other. Pinkie was the first to pull back from the deep kiss, a trail of saliva connecting the two ravenous tongues.

“Still embarassed?” she asked, wiping her mouth clean.

Sunset turned to the side, her cheeks flushed red with excitement. “N-no, but why are you doing this?”

Pinkie scooted a little way down Sunset’s body until her shaft was fully on display. Pinkie licked her lips hungrily, her fingers softly rubbing down that fleshy tube through the fabric of Sunset’s pyjamas. “To make you feel comfortable, silly! I’ve seen you walking around the school, always checking yourself. Don’t you want to feel a little more comfortable with this little treat?”

Sunset shot Pinkie a serious glance. “Little? Treat? Have you seen this thing? Like, actually seen it? It’s monstrous! It makes me look like a fr-”

Pinkie pressed a finger to Sunset’s lips. “Are you kidding?! It makes you look super awesom-azing! You’re like best thing ever for sex!”
Sunset turned her head partway towards Pinkie. “Wait, you honestly think that?”

“Yeah! You’ve got a body that would make anyone jealous! Even the guys! You should embrace that!”

Pinkie tugged at Sunset’s waistband, revealing the first few inches of Sunset’s shaft. The slightly darker orange clashing with her natural body colour. She took in a deep breath of that masculine scent and its combination of feminine undertones. Bitter yet sweet, the perfect combination to represent Sunset Shimmer. The burning lust within her only grew stronger as she drank in that heady mix of pheromones. She couldn’t believe how hot it made her and how the pyjamas had kept it hidden from her. Sunset would soon see the benefit of their little fun, Pinkie was sure of it. She tugged the waistband of Sunset’s waistband a little more forcefully, but it wouldn’t budge. The plush curve of Sunset’s rear combined with the friction of the floor, halted her progress. She looked to Sunset and her friend looked back at her. Pinkie put on the puppy dog eyes just to make sure that Sunset fell for her charms and allowed her progress to continue. She watched as Sunset looked down again, before every so slightly raising her hips. Pinkie took no time at all to exploit Sunset’s action, yanking her pyjama trousers down to her ankles. Sunset’s shaft swung up, presenting itself to the horny baker. Oh the joy on her face as Pinkie got to see what she’d craved for so long. The towering pillar of flesh, slick with the salted pre-cum of Sunset’s evident arousal, veins bulging along the sides. Pinkie drank in every detail with her eyes, marveling at every twitch and pulse. The power running through that shaft was awe-inspiring. Pinkie’s tongue lolling out of her mouth, causing her to pant like a bitch in heat. Pinkie leant in close and felt the heat washing over her face, pulsing waves of musky air assaulting her senses. Her tongue hung inches away from getting a taste of the flared head, but she restrained herself. Bitches like Pinkie didn’t get to start at the top, they had to start at the bottom.

So down she went, passing by inch after inch of Sunset’s engorged, shimmering, pole. She paid particular interest to the medial ring, an unusual addition not normally found on regular human malehoods. Pinkie saw it as a challenge marker, a signpost for her to reach later on when she introduced this shaft to her mouth. Finally, she reached the base of the shaft and by extension, those pendulous balls. Both of them sat in Sunset’s lap, no doubt churning up a storm thanks to Pinkie’s efforts. Pinkie took each one in a hand and marveled at how they filled her palms. Even as she gave them a little squeeze, they only swelled a little larger, eliciting a gasp from her partner. That was it for Pinkie, she’d been teased enough. She needed to get better acquainted with this shaft and she wasn’t going to wait a moment longer. She lowered her head and stuck her nose right between those balls, taking in a deep breath of Sunset’s scent. Her senses lit on fire, her eyes rolled back in her head as she gasped, shuddering softly. Sunset’s bodily perfume, a heady mix of old pre-cum, neediness and sweat. Pinkie took deeper breaths of the intoxicating aroma, sliding her nose up and off the side of Sunset’s shaft, locking eyes with her friend. Her tongue rubbed against the base of the shaft, causing it to twitch and pulse in apparent delight.

Sunset didn’t know what to think. Everything was moving so fast, her mind was struggling to piece it all together. The rational part of her mind was slowly losing out to the building feelings of desire and lust. She found herself wanting to give in to those feelings and just ride Pinkie for all she was worth. Pound that pink posterior until Pinkie did nothing but scream her name. That wasn’t what friends did though, was it? Pinkie certainly seemed to think so and admittedly Sunset was still a little new to the whole friendship thing. She bucked her hips as Pinkie began to lick across the base of her shaft, her balls smacking into Pinkie’s chin. Shivers rushed through her body, pangs of pleasure surging up and down her spine. Hot gasps escaped her mouth, coupled with small yelps of delight. Sunset’s mind continued to twist and turn with conflict on just what she should be thinking, but one thing was evident. Her thoughts were becoming more and more depraved by the second. The unease in her eyes began to melt away, her hands flexing as she prepared to take control from Pinkie. Just then, Pinkie sat up and slurped her tongue back into her mouth, yanking her shirt off with ease. Her breasts were something of the subject of speculation between the students of CHS. Plenty of students had speculated on whether or not they were naturally big or if Pinkie had underwent surgery. At this moment in time though, that topic wasn’t really up for debate. Sunset was delighted to see Pinkie’s mountains of flesh surge forward and envelop her cock. The doughy warmth felt incredible, but it felt even better when Pinkie mashed her hands into them. The extra pressure tightening the tunnel of heat around her shaft, causing Sunset to buck a little wilder.

“Feeling comfy yet?” Pinkie asked, leaning down to lap at Sunset’s flared head as it poked from her cleavage.

“A-Ah, yeah. Do ya think, you could, uhm, y’know…” Sunset blushed and pursed her lips, eliciting a giggle from Pinkie.

“Sure! I’d be delighted!” Pinkie replied, not even waiting for Sunset to reply before impaling her mouth on Sunset’s head.

“Pinkie, I ah, I didn’t- Gah!” Sunset shivered and fell silent again, her mouth falling open.

A spurt of salty pre jettisoned itself into Pinkie’s throat, earning a sound of delight. Pinkie’s mouth was delight to behold. The way her lips pursed tightly around the flesh, her cheeks sucking in and out to add extra pressure. Beyond that there was Pinkie’s tongue, the way it lashed and thrashed against Sunset’s head drove the orange human wild. What had started as casual thrusts and the occasional moan turned into a cacophony of noise as Sunset screamed and slammed her fists into the floor. She was being driven wild and Pinkie showed no signs of relenting. Which was fortunate for Sunset because she was rapidly approaching a climax. Further spurts of pre splattered messily against Pinkie’s tongue, as Sunset’s body was racked from head to toe. How did males manage to survive with this level of delight coursing through them every time? Her whole body was so sensitive, even in places she didn’t think possible. Every movement, whether it be from Pinkie or otherwise felt like being touched by a heavenly body. Already she could feel the pressure at the base of her cock beginning to increase. Her balls pulled tight against her as Pinkie began her final assault. With a loud sucking of her cheeks inward, Pinkie coaxed Sunset to her release.

With a howl of erotic satisfaction, Sunset blew her load down Pinkie’s throat. Her friend didn’t fight it, instead she welcomed it, gulping down load after load that Sunset provided. Sunset dug her nails into the floor, trying to speak but all she could get out were low gurgles and gasps. Pinkie on the other hand talked around Sunset’s shaft, pausing every so often to gulp the cum that was bulging out her cheeks. What she said was completely unintelligible, but it was no doubt an expression of just how much she loved it. After a few minutes, Sunset was still going. Her orgasm had slowed a little, but she was still pumping literal gallons of seed into her partner. She had to wonder where her balls had stored it all, but she didn’t care. Even as Pinkie’s stomach bulged out enough to roll her shirt up and over her stomach, she didn’t mind. The obscene sounds coming from Pinkie’s gut only served to increase the pleasure of both ladies. The bulge in Pinkie’s stomach only continuing to grow and swell with each gurgle, before Sunset’s orgasm died right down. Pinkie flopped backwards, her swollen gut spilling out over her body, gurgling with contention. Sunset breathed a sigh of relief, her dick dropping down onto her stomach with a wet ‘thwap’.

“Wowee, Sunset! That was incredible!” Pinkie took a pause for a deep breath, the her bulging stomach putting pressure on her lungs. “And it tastes so mmmm! It’s like sour candy!”

“Pinkie, I, gah…” Sunset covered her face in her hands. “I can’t believe we’ve just done this. What would the others think?!”

“Our friends? They’d love it!” Pinkie raised herself up from the floor and dropped back down again, bouncing in giddy excitement was hard when you were so full. “You haven’t been to one of my special sleepovers, have you? Next time I host one, you are SO coming as well!”

“Special sleepovers?” Sunset wasn’t even sure she wanted to know. All she wanted for the moment was a little rest and maybe a few glasses of water.

“Yeah! They’re great fun, and I’ve never had anyone leave that wasn’t feeling a whole lot more relaxed! Trust me, it’ll-” Pinkie yawned obnoxiously. “-be great fun!”

Then, in a matter of seconds, there was a soft thud as Pinkie fell asleep. A further minute more and she was snoring like a bulldozer, her stomach gurgling as it digested the meal that Sunset had poured into it. Speaking of Sunset, Pinkie’s partner in crime had mixed feelings about the whole experience. On the one hand, she found an outlet for the aching in her loins that had been going on for years. On the other, Pinkie was going to force her to show it off to her friends. While she didn’t doubt Pinkie’s claim that they’d love it, she was still rather apprehensive. Still, she could deal with that when the time came, for now it was time to sleep. She pulled her trousers back up and tucked her softening shaft under her shirt. She yawned and closed her eyes, allowing herself to drift off to sleep. What an unusual, yet thrilling party this had been.
