With a Creamy Filling
“Pinkie,” Twilight gasped, staring down at her fork, “this cake is amazing - maybe your best one yet!”
The brilliant purple confection, a roll of violet sponge cake and rich frosting, tasted fantastic; it wasn’t as sweet as some of the other treats she’d sampled, although she counted that as a plus. Thus far, that evening alone, she’d tried no fewer than six different pastries that her culinarily competent companion had concocted.
Waving away the Princess’ compliment, Pinkie Pie’s smile broadened. “It’s an Ube cake with buttercream frosting! You can take the rest home, if you want. Trust me, I do not need more sweets sitting around,” she laughed, glancing at the remaining desserts.
The offer, while appreciated, gave Twilight a moment for pause. Binging on sweets for a single day wasn’t that bad, yet she’d been invited over several times in the last month for samplings. It wasn’t like she minded helping with her friend’s edible experimentation, although she feared all the rich food and sugar was beginning to take a toll. Glancing back and appraising her behind, she scrunched her snout.
“I might have to pass on that offer, Pinkie,” the alicorn politely responded.
Truth be told, she had been tempted to take the cake home - several of them, in fact. Each of the pastries or pies had a unique taste and flavor profile which she found delightful. Part of her wondered if having a penchant for sweets was just part of being a Princess, considering Celestia’s fondness for sweets - regardless, even if it wasn’t, the thought gave her a giggle.
“Awwwww,” Pinkie groaned, her fluffy mane deflating slightly. “Are you sure?”
Hopping from her chair and wheeling around, the young Princess presented her rear to the sullen mare. “I’m not sure if you noticed, but all these treats have given me a little more cushion for the pushin,” she groaned, air quoting with her wings. “It was hard enough having to get used to certain parts of being a Princess, so the last thing I need is extra padding back there.”
Twilight had gotten more than just a pair of wings, back when she’d ascended to an alicorn. Combining traits of all types of ponies, of both genders, she found herself wielding a rather hefty package. Honestly, she hadn’t been upset with the additional equipment, since Celestia and Luna each had a set, although getting used to it had been another story entirely.
Staring over at her friend’s backside, Pinkie hopped from her chair. “Twilight, it’s not that big,” she remarked, trotting closer to the Princessly posterior. “I mean, I can name a half dozen ponies right now who have bigger behinds. There’s Mrs. Cake, Celestia, Marble, Yona, Velvet, and me! Besides, when’s the last time you heard anyone complain about a big booty?”
“You’re just saying that,” Twilight muttered. Glancing over her shoulder, seeing that her rump held the baker’s attention, she stiffened.
She’d had suspicions that there was some ulterior motive to Pinkie’s calorically enhanced generosity, yet she’d never been able to verify it. It was no secret that the pink party pony had a weakness for desserts and celebrations, although the energetic mare may have harbored another interest. Turning her head away, lest her friend see the smirk creeping across her face, the Princess cleared her throat.
“If I didn’t know any better, I’d say you were trying to fill me out a little,” she giggled.
“Well…” Pinkie awkwardly began, rubbing the back of her neck. “Since you’re going to be taking Celestia’s place soon, I figured you’d want to be ready in every way! That throne doesn’t look too padded and I thought that having an extra bit of cushion might make sitting for long periods more comfortable for you! It’s not like I could put pillows on the throne or anything!”
Reaching back and sinking a forehoof into her growingly ample rump, Twilight knit her brow. While she hadn’t gained a ton of weight, it almost seemed like every ounce of it had gone right to her tush. Outside of catching the occasional townspony sneaking glances at her rear, nothing much had changed - still, she’d rather not pack on any more pounds.
Shaking her head and rolling her eyes, Twilight found the notion absurd. “I’m pretty sure that I could put whatever I wanted on the throne. Pillows, maybe a throw blanket, a hidden compartment for books -“
“Other ponies?” Pinkie chirped.
“I...excuse me?” the Princess murmured, looking back in confusion.
“Other ponies,” the mare repeated. “You could sit on ponies on the throne! Wouldn’t that be silly?”
As preposterous as the idea was, it gave Twilight an idea. If Pinkie really did have a thing for derrieres, she’d soon be able to prove it. Spinning in place, she faced her friend and smiled broadly. “Are you volunteering?”
The Element of Laughter giggled and hopped in place, before springing into one of the nearby chairs. Adjusting herself on the seat, as any pony would normally do, she made herself comfortable and patted her lap. It was clear that she didn’t mind the offer, yet the Princess had something else entirely in mind. Slowly, surrounded by a raspberry aura, Pinkie was levitated into the air.
“Oh no, no, no, no, no! This just won’t do at all! A royal chair requires only the best cushion available,” Twilight tutted, steadily whirling the mare upside down. Easing her friend back onto the chair, with her head resting squarely on the seat, she fought back a grin. “Much better…”
Pinkie looked about in confusion, still chuckling at what had to be some silly joke - that was, until the alicorn turned around and started trotting in reverse. The growing form of Twilight’s succulent rear grew closer and closer, while her head sat upon the wood of the chair, causing her to gulp. The Princess’ buns glided past one another, giving her fleeting glimpses of the dickmare’s ripe nuts and pronounced pucker. It was only then that she knew what the alicorn had meant.
“T...Twilight, I - um - I’m not sure if…” she trailed off, as her friend’s rump loomed above her.
The Princess ground a halt, mere moments before she rested herself on Pinkie’s face. Though she’d had every intention following through with her hastily laid plan, another avenue had presented itself. If the party pony was going to be her seat, there’d be no harm in adding a little extra stuffing. Rearing onto her hind legs and wheeling around, she placed her forehooves on the arms of the chair.
Essentially stradling the mare’s head, leaving her package hanging just over Pinkie’s face, Twilight hummed thoughtfully. “Maybe you’re right…”
“Wait, I am?” Pinkie asked, sounding somewhat surprised.
“Maybe I should give you a nice, big cream filling first,” the alicorn mused.
“Cream filling? I’d love - Glk!” whatever the baker had been about to say was lost, when the Princess rammed her hips forward. With almost supernatural precision, the rigid length of regal marecock was driven past the mare’s lips and into her gullet, as the alicorn took advantage of the opening.
The warm, snug confines of Pinkie’s maw sent a shiver of delight up Twilight’s spine. Far, far better than a hoof or act of magical masturbation, having her length constricted by another’s mouth spurred her to continue. It wasn’t her fault that it felt so good and she’d be darned if she was going to stop before she’d finished. Steadying herself, steadily humping her friend’s face, the Princess closed her eyes and fixated on the bliss.
Caught off guard, there wasn’t much Pinkie could do. Gagging lightly on the deeper thrusts, taking breaths when she could, her senses were quickly overwhelmed. The Princess’ musk flooded her sinuses, while the salty, cloying flavor of sweat and pre-cum coated her palate. Just as she was beginning to relax a touch, the alicorn’s pace shifted.
Stepping forward, Twilight hilted her friend’s muzzle. The sensation of Pinkie’s throat clenching around her shaft, while she fucked the mare’s snout, was absolutely astounding. Groaning, she pumped her hips harder and faster with each passing second. Losing herself, giving in to the pleasure, her weighty balls rhythmically slapped against her friend’s face.
While it wasn’t the first time Pinkie had serviced a stallionhood, she had never tangled with somepony as well endowed and forceful as Twilight. The strength of the alicorn’s thrust was hard enough to deal with, but the monumental size of Princess cock swabbing her throat was insane. Caught up in the moment and caught unawares by having her muzzle hilted, it took her a few seconds to realize that she couldn’t breath.
“Sweet Celestia, this is incredible,” Twilight moaned, furiously screwing her friend’s face.
Though she’d had no idea she would end up doing something so naughty with Pinkie, she wasn’t about to complain. It had been ages since she’d fooled around with anypony and she’d been a bit pent up. Running a school, preparing to move to Canterlot, and helping with friendship problems throughout Equestria had left her with very little free time - as such, she tended to neglect her more primal urges.
Enwrapt with pleasure, only dimly aware of Pinkie’s lack of air, Twilight pushed herself to the brink. Shuffling forward the smallest bit, she switched gears; the long, steady plunges she’d been using transitioned into a savage, jackhammering series of thrusts. Though the mare writhed and squirmed beneath her, yet she continued undeterred.
As the seconds dragged on, the passionate fire within her roared into an inferno. Keenly aware that she was inching closer and closer to her limit, she raced for the finish line. Hauling nearly the entirety of her length from her friend’s snout, causing her girthy medial ring to Pop out of the mare’s lips, she braced herself, grunted, and drove her hips forward.
The momentary reprieve allowed Pinkie to get the smallest gasp of oxygen, yet it was all too brief. With her esophagus stuffed with marecock, as the Princess hilted, a warmth permeated into her belly. The heat radiated through her, but it was the pressure that really caused her to struggle. With her gut angrily gurgling in protest, swelling and ballooning outward, and her eyes rolled to the back of her head.
Fitfully humping her friend’s face, Twilight rode out her climactic ecstasy. Dumping a load into a pony was way more gratifying than getting herself off. Stepping back and reluctantly withdrawing her softening shaft from the mare’s abused gullet, she gradually dismounted from the chair.
As she stood before the semi-conscious Pinkie Pie, she reached out and prodded the catatonic pony’s stomach. Positively bloated with alicorn seed, it wasn’t surprising that the mare was left in a cum-drunk stupor. Smiling to herself and turning around, pleased with her efforts, the Princess readjusted her friend and slid her back just a hair.
Easing her tush onto Pinkie’s face, Twilight contentedly wiggled her backside and got comfortable. “Much better…”
Some part of Pinkie knew she had to resemble an eclair. Stuffed with cream, so swollen that she could barely move, she was dimly aware that there was a plush purple Princess posterior on her face. Languidly, drawn by the alicorn’s heavenly scent, she brought her nose to the source. As her lips graced the fleshy, supple donut above her, she began licking away.
“That’s right,” Twilight giggled, grinding her ass on the mare’s face, “really get in there.”
Even though she hadn’t planned on Pinkie being so enthusiastic, she wasn’t about to complain. As a Princess, she thought it only fitting that one of her loyal subjects be lucky enough to lavish her royal rump and she had no regrets about letting her friend do the job. With a heavy sigh, she rested more weight on the pony under her.
With her back against Pinkie’s belly and her rear bearing down on the mare’s face, she gently rocked forwards and back. Having her ponut serviced was all well and good, although she wasn’t opposed to having her marehood get a bit of attention. Situated between her plump nuts and taut backdoor, her drooling snatch had gone wholly untouched throughout the experience - at least it had, until that moment.
With a juicy Princess pussy and backdoor dragging over her mouth, Pinkie did what she could to service her friend. Though she could get the occasional bit of air, breathing properly was still a trial. Entombed between Twilight’s chubby cheeks and thick thigh, her tongue worked furiously. The tastes, smells, and the sensation of being trapped so thoroughly left her with few other options. Even if she wasn’t stuck - which she most assuredly was - she was too weary to object.
Twilight had to admit, she was pleasantly surprised with how eager her friend was with the affair. After having several days worth of foal-batter pumped down her throat, the mare was still doing her best to be the life of the party. Pausing, just as her sopping wet marehood bore down on her seat’s snout, she gyrated in place.
“You can breath, right?” she inquired, almost as an afterthought. While she couldn’t see it, she felt Pinkie lethargically nod. Sure enough, a muffled sound of agreement drifted to her ears. “I hope you’re comfortable down there, since I have got to finish this Ube cake you made,” she purred, levitating the remainder of the sweet treat and a fork towards herself.
Helping herself to another slice of the confection, while her friend lavished her backside, the Princess savored every last bite...
