Shining Armor's Storybook Hour

Pet to Slut

Previous Chapter

Shining found himself only able to whimper and moan as his face was gently kneaded into the bed, feeling his master’s hot cock hotdogging between his thick cheeks and letting out a good bit of precum to lubricate the way.

Humming softly, Sombra humped the large rear before him for a few more moments, letting out grunts and guttural moans as his shaft was pleasured on all sides by the huge ass. Even still, he pulled back from the butt to a chorus of complaining whimpers from his Pet.

“Now now, be patient.” Sombra grumbled as he stepped over to the bedside table, moving slowly and teasingly as he left Shining to buck his tiny cock against his belly uselessly.

Ignoring this, the tall, dark, and handsome stallion rummaged through the drawers with one hand, the other stroking along his cock and dragging precum all over it to lube himself up. Despite this, with a casual grin, he found exactly what he was searching for.

Pulling the bottle of actual lube out of the drawer, he hefted the small bottle as he slowly walked back into position behind his Pet, grinning and chuckling as he clamped a large hand around one ass cheek, pressing his palm against the feminine stallion’s massive cutie mark. This drew needy moans from shining.

“Well, you seem eager.” The muscular stallion commented as he steadied the swiftly humping hips of Shining. After the bellyfucking drew to a close, Sombra popped the top off the lube and spread it liberally all over his shaft before stroking it in thoroughly.

Shining moaned out happily and wiggled his hips to entice Sombra, still fighting to obey the silent order he’d been given despite the twitching of his hips and needy throbbing of his cock.

“P-please, Master.” He whimpered submissively, his hands moving back to attempt to spread his rump’s cheeks, but only serving to lay them on his very in the way belly. He wasn’t exactly unhappy with this, just playing with his Master given fat with glee.

With a cocky grin, Sombra pressed the thick tip of his cock against his Pet’s tight hole. But he chose to stop it there, instead leaning forwards to whisper against Shining’s ear. “Please what, Pet?”

Groaning at the sheer dominance of the stud above him, and the huge cock pressing up against his tight non-virgin hole, Shining bucked his wide ass back to try and fuck himself on the shaft. But, being smarter, Sombra pulled back just as much as his Pet pushed his butt out.

Figuring this wasn’t the best course of action, Shining bit his lip and mumbled under his breath. With a blush on his face as he nuzzled the bed sheets. Then, drawing his muzzle from the sheets, he opened his mouth gently.

"Please fuck me, M-Master..."

Sombra couldn't help but chuckle, grinding a bit harder against Shining’s tight hole. “I don’t believe I heard you, Pet. Speak up a bit.”

“Yes Master.” Shining blurted immediately after the order, blushing hotly as he was forced to obey orders. “P-please f-fuck me, Master!” He then exclaimed, maybe a bit too loudly, with clenched eyes.

This sudden change of tune made Sombra let out a small purr deep in his throat as he pressed his muscular chest against his Pet’s soft back. “Well now, that must make you feel a whole lot better, doesn’t it, Pet?”

A moan escaped Shining’s mouth before he could respond, pressing his back up with a happy grin. “Y-yes Ma-AH~!”

Shining found himself cut off as, suddenly,Sombra pressed his hips forward, popping the head of his shaft past Shining’s tight entrance easily and safely due to both the lube and the constantly leaking precum.

The submissive Pet’s eyes rolled back in his head as his Master slowly sank inch after inch of cock into the tight hole before him, only stopping once his hips threatened to be engulfed between the massive, gently wobbling cheeks.

With a strange sort of grin, King Sombra roughly pressed his hands on the offending cheeks, pulling them apart and sinking even further in with a deep groan as he hilted. He then just sat there with a cocky grin, the only movement he made being short humping as his hands groped against Shining’s ass.

Feeling his sensitive rump being fondled along with being filled to the brim, all Shining could do was moan out passionately into the air as he moved his hands to strongly grip at the bed sheets. He groaned and panted out into the air, bucking his hips back and forth as he both craved more of Sombra’s cock and to fuck his own belly. He had many options.

Feeling Shining buck back against him, feeling his miniscule balls knock against The King’s swollen and full nuts that just churned full of seed, Sombra pressed his hips slowly, teasingly back out of his Pet, drawing the thick, flared head of his cock along Shining’s now very sensitive insides.

And, pathetically, that was all Shining needed. Pressing against his huge belly, Shining’s tiny cock strained and twitched as pleasure flooded him, his grape-sized balls pulling up as far as they could go.

Just as Sombra started to rut his pet, Shining clenched his eyes shut and let out a loud, whining moan as his shaft shot out a miniscule amount of cum along the bottom of his belly, then just continued as it attempted to shoot off more, but ended up giving nothing but a little pre.

As his Master continued to pound into him, gripping his arms around the thick, fatty waist for leverage, the Pet felt his rump clench around his mate’s cock, trying this soon to try and milk it of its hot seed.

Blinking, Sombra came to a halt, groaning gently as he felt the tight clenching, then looked down at Shining in shock. “A-already? You reached orgasm already?”

With a heavy blush, Shining covered his face with his dainty hands and whimpered out. “I-I’m so s-sorry, Master!” He cried out gently, but still bucked his rump back to pleasure his Master like a good Pet should.

After a few moments of strange stares, Sombra pressed his hips roughly against Shining’s plush ass. “Well, it seems that Master is going to have to teach his Pet what stamina looks like.” And, with that, and without even waiting for Shining’s response, Sombra gripped Shining’s love handles hard and drew his hips back swiftly.

Then he began to fully rut, bucking and rolling his hips quickly into the still gently clenching hole before him. He grunted and groaned loudly as he humped deeply into the ass, sinking in and out as fast as he could like the dominant stud that he was.

And then, moments later, he suddenly felt his balls drawing up and pressing tight against his crotch. Moaning loudly as his fat, very swollen apple-sized balls twitched, he bottomed out in Shining one last time, his cock firing out thick load after thick load of his hot cum.

Normally the truly excessive amount of cum would have pressed Sombra’s mate’s stomach out with the sheer amount, but it hardly put a dent in inflating Shining’s big ball of a belly.

Grumbling and whimpering deeper, Sombra just humped and ground his hips against his Pet’s. All he could do was grunt as he leaned down and held Shining close to him, wrapping his arms around the ball of lard while he unloaded all he had.

Minutes later, after finishing the seed spreading, the dark grey stallion flopped down on his lighter, plusher mattress of a stallion, letting out a pathetic huff of a sigh. “Oh Gods damn it.” He muttered gently under his breath.

Suddenly there came a sweet, feminine laughter from the corner of the room, obviously directed towards the two stallions. Then the corner began to shimmer, then glow with a pink aura as an equally pink pony was revealed.

The plump pink mare pressed a hand to her lips, giggling out as she stepped from her hiding space. Now, to call Princess Cadence curvy would be selling her very short, despite how very short she was. She may have been simply ‘curvy’ before Flurry Heart, but since getting pregnant her curves just got much more.

Her breasted pressed out from a simple, perky D to an F that neither she nor Shining could keep their hands off, but they especially couldn’t resist teasing her thick, leaky nipples that seemed to always be hard and visible no matter what she wore. Also inflated we're her plush rump, though very flat compared to Shining’s currently, and her wide and excessively feminine hips that screamed motherly to anyone she swayed past. Her belly hadn’t quite recovered as well, still somewhat plump and squishy, but nothing when compared to Shining’s.

Even still, this goddess of fertility was currently looking very non-feminine as she guffawed at the two post-mating stallions. This drew a huge blush from Sombra as he proceeded to bury his face into shining’s back. Shining, however, blearily looked over at this new mare as he absentmindedly ground his rump back and wondered why he wasn’t being rutted.

Princess Cadence sat herself down on the edge of the bed, still laughing but this time pointedly at Sombra. “So much for showing him what stamina looks like, eh?” She teased, nudging him with an elbow.

“Shut up!” The dark stallion growled as he glared at Cadence, his eyes lighting up red and menacing.

But she just continued to laugh him off, waving him off with a hoof. “Come on, drop the act. We all got what we wanted.”

Sombra attempted to stay grumbly and socially angry, but broke with a short laugh, turning to look away from the plump mare as he chuckled softly. “Fiiiiine!” He said as he rolled his eyes.

Pulling back from the pillowy stallion below him, drawing his softening shaft from the still well-lubed rear. With a heavy sigh, the dark stallion lit his horn with light amber magic.

Needless to say, his body shimmered as his coat gently got lighter, though stayed darker than his Pet’s. His eyes changed from a deep, frightening red to a bright green, matching Shining’s collar well. And, finally, his horn straightened and became entirely grey as opposed to having a red tip.

Shining, craning his neck and wiggling around to look at his Master, gaped openly as he saw how much he had changed.

Upon seeing this, Sombra shot a dopey grin at Cadence, pointing a thumb at the fat stallion. “Are you gonna…?”

“Oh, right.” Cadence smacked the side of her head gently, then lit her horn and focused her aura around her husband’s head for a few moments. Then, with a bright grin, she clamped her hands together and shrugged. “Well, I think I got most of it. And whatever’s left should be fun to play with, eh Shiny?” She then nudged her lover’s big belly.

All Shining could do was blink as he, now with full understanding of what had gone on, stared up at Cadence, then down at his huge body, then over to Sombra, then back to his wife.

“What the fuck?”

This eloquent phrasing caused both Sombra and Cadence to snicker gently, the pink mare even covering her mouth. This, however, wasn’t able to stop the two from bursting out laughing. Cadence gave into it immediately, flopping back to use her husband as a pillow and giggling even harder as she felt him wobble under her.

Sombra took a similar approach, pressing a hand against Shining, propping himself as he held the other around him, chuckling so hard it was painful. Then he flopped as well, leaning against Shining’s left side and creating more jiggles and wobbles.

After a few minutes, the laughter died down to just little chuckles every now and then. This allowed Cadence to look lovingly at her confused and embarrassed husband with a big grin. “Weeeeeeelll… Sombutt wanted to have fun times with an obese pony-”

“Who were more prevalent in my time, I might add. At least I fed my subjects.”

“Yeah well at least we didn’t willingly kill anyone.” Cadence said with rolled eyes, craning her head up to make sure Sombra heard it. Then she looked back down at Shining. “Anyway, he wanted to love up on a big fatty, so we all decided to fatten you up and let him have his way with you for, heh, hours~.”

Sombra grumbled loudly, crossing his arms and letting out a loud huff. “Well, you try to suddenly be reintroduced to a fetish after a thousand years and not finish in a few minutes.”

“Whatever you say, Sombutt.” Cadence told the blushing stallion teasingly.

“So you just decided to do all this without telling me?” Shining asked with a bit of loudness, though, upon looking down, he gave a small grin, then a huge blush as his small cock strained against his belly.

Lighting her horn, Cadence used her magic to reach into the bedside table. Pulling out a stack of papers, she placed them in front of Shining’s face. “Well, hon, you did agree to it. I just made it so you couldn’t remember, which was covered here.” She opened the packet and pointed one bit on one page.

Reading it over, then getting bored, then skipping to the end, Shining found his signature under a bunch of legal jargon. With a defeated sigh, he superflopped on the bed, making massive waves in his body, and wiggled. “How’d you even get it done? You can’t draw!”

“I CAN!” Sombra retorted loudly, getting fed up with petty squabbling and totally not being completely embarrassed due to his lack of any stamina. He then crossed his arms even harder and grumbled to himself. “Can’t even be bothered to care about my many talents.”

“Well I did the magic, which was the more important bit.” Cadence fought back. “And the writing, which is the most important bit of any media. You can’t have a good story without good writing.”

Before Sombra and Cadence could go to blows, Shining wiggled a bit more. “That’s all well and good, but can I have my muscles back please?” The feminine stallion wobbled and jiggled as he weakly flailed about, tiring himself out quickly as he whined out loudly.

“Nah.”

“Nope.”

“Well, it’s two to one.” Cadence told her husband with a smirk, turning over and pressing her face against the side of her husband’s belly and nuzzling lovingly against it for a few moments, drawing whines and moans from the stallion. Pulling back, she rested against him. “But don’t feel bad. We’ll only keep you as a mattress stallion for a week. Then we can change you into something else!” She poked a hoof into Shining’s belly with a giggle. “Did you know Sombra and I share a transformation fetish, ‘cause I didn’t until now~~!”

Sombra just grumbled in agreement, but was too busy tiredly yawning and pressing his head against the pillow of a stallion he was provided.

As the two ponies prepared to nap on him, Shining just resigned himself to his fate as a pillow pony and a transformation Pet, just the thought sending waves of pleasure through his body for a moment. With a deep sigh, he planned his head against his own pillow, sadly not as warm or plush as he was, and shut his eyes.
