Sombra pounded his belly. Like a drum, its thunderous vibrations rang out through the throne room, his entire massive gut and moobs jiggling like jello. He groaned as his fat ripples and shook, the smack still ringing in his ears. Gods, but it felt good whenever he did that.

Another half-second passed before he grew impatient. Scowling slightly, Sombra leaned over his belly - being far too large to stand up easily - and called out: “Servant! What are you waiting for!”

“Coming, your majesty! Coming!”

Almost as soon as the last word left Sombra’s mouth, Double Diamond crashed through the servant's door. He was babbling what sounded like a stream of apologies, but Sombra had already tuned them out, instead choosing to focus on another sense entirely.

Diamond was already nude, Sombra noted approvingly. His queen must have been doing a good job of training him. His cock slapped against his thighs with every step, and it was hard for the greedy king to keep his eyes from hovering over each and every part of Diamond’s body, from the lean muscle on his arms to his thick, corded thighs, and even to his wide, almost feminine hips. Sombra smirked to himself, chuckling darkly in the back of his mind. Oh, yes. Double Diamond would do well.

Double Diamond bowed low to the ground before him, but Sombra would have none of it. “Get up,” he barked. “And get over here.”

Diamond slowly rose and approached. He made sure to keep his vision below the King’s. “Yes, your majesty?”

Sombra ignored him. “Mmm,” he purred. He reached out one flabby arm and laid it on Diamond’s flaccid cock. The smaller stallion startled, but didn’t otherwise react. His member looked smaller than Sombra’s own (which was both good and bad; Sombra couldn’t permit any stallion larger than he in his kingdom, but he always enjoyed stealing their excess size and adding it to his own to fix things), but his tennis-ball-sized testicles hung fat and heavy between his legs. Sombra licked his lips hungrily. He could feel his own balls churning and sloshing beneath his mountainous gut, more than ready to spill their seed.

Not yet, though. “Do you like this?” Sombra asked idly, his sausage-thick fingers still stroking up and down Double Diamond’s shaft. To his credit, Diamond’s cock barely twitched, and he let out just the barest of whimpers. Good. It wouldn’t do for a servant to have no self-control.

Diamond’s mouth quivered. “I will like it if my King likes it.”

Good answer. “Then I like it,” Sombra said. His hand slipped a little lower until it was fondling the top of Diamond’s balls. “In the future, give honest answers to my questions. Lay a hand on my stomach.”

“My King, I cannot touch your person. I - “

“I gave you an order.” Sombra glared down at Double Diamond. “Do you dare disobey your King?”

“No, your majesty,” Diamond quickly said. Slowly, hesitantly, he raised his hand and lowered it back down onto Sombra’s gut. Sombro groaned a bit as he felt Double Diamond’s fingers pressing into his fat, his stomach jiggling slightly around the point of contact.

“Do you enjoy that?” Sombra asked.

Double Diamond nodded quickly. “Very much, your majesty.”

“Very good.” Sombra noted approvingly that Double Diamond’s cock was beginning to rise. A controlled servant was one thing, but a servant without a libido was no use to him at all. “You like my gut?” Another nod. “Tell me why.”

Double Diamond bit his lip and shifted his hips a little. “It’s…just so big. Your majesty. So enormous, so soft, so powerful. I’ve never seen anything like it.”

“Would you like to feel it even more?”

Double Diamond gulped, then nodded.

“On your knees.” Sombra’s voice now had a bit of an edge to it. “In front of me. Now.”

Sombra smiled to himself as Double Diamond quickly knelt down. A crackling black shadow surrounded his horn as he levitated his gargantuan, gurgling gut a few inches into the air.

“You’re going to be my cockwarmer,” Sombra said pleasantly. “My official one, at that.” His own cock, a royal eighteen inches and change, was already hard. It rubbed against the bottom of his fat gut, throbbing every time he lifted it an inch more. “And, seeing as I’m such a bountiful stallion as well, you’re going to serve as the royal belly-rest as well. Every day while I’m at court, you will hold my cock in your ass and my belly on your back as I eat and rule. Is that understood?”

“Yes, your majesty.” This time, Double Diamond’s voice was barely a squeak. Sombra’s grin deepened.

“Then back up, O Royal Cockwarmer. And let us begin.”

Double Diamond watched the entry of the court with awe. He’d been a servant in the palace for the past three years, but never before had he been allowed in the upper echelons of Imperial society. He watched nobles from all over the empire entering the great hall. When they bowed low before King Sombra, their own fat bellies and thighs jiggled like jello. A new king had brought a new trend, and none of the nobility liked to feel unfashionable. Of course, none of their stomachs even approached the glory of King Sombra’s...and from the bulges shifting on the crotches of the noblemen, there wasn’t a stallionhood among them that could match the glory of their king’s.

Some part of Double Diamond liked to imagine that they were bowing to him, but the greater part of his mind was focused on his king’s scepter. Sombra had shoved his cock deep in Diamond’s ass before the proceedings had begun, leaving it there to drip and throb.

Double Diamond had had to stifle a groan when he’d first felt it enter him. He’d never seen a cock that large before, let alone taken one. Yet when Sombra’s shaft had slid inside of him - heavily lubed, of course - Diamond had let out a sigh that was equal parts pleasure and pain.

And the pain had gone, after a while, his body adapting to the magnificent size of King Sombra’s stallionhood. Its size was a testament to his king’s masculinity, and Double Diamond couldn’t have been prouder to hold it inside of him. It made him feel full, but with more than just its size. It filled him with pride, with joy, and - to no small amount - with arousal.

Deep inside, he wondered whether the king might someday take him on as a concubine. A royal cockwarmer was a privileged position indeed - but a place in the king’s bed? There could be no greater honor...or pleasure.

He grunted, feeling Sombra’s shaft slide around inside of him as the king gave a small jerk of his hips. Evidently, King Sombra enjoyed reminding his servant of his position. But Double Diamond didn’t mind.

And it was hard to forget his place anyway: Sombra’s enormous, magnificent gut surrounded the entire upper half of his body, concealing his back and sides from view. Only Diamond’s head, shoulders, and arms were visible to the court. His knees creaked and his elbows throbbed as he struggled to bear the weight of his king’s stomach on his back.

A full-grown stallion - at least - could have fit in the incredible volume of that belly. Double Diamond’s own cock began to harden, a few drops of precum falling to the marble floor, as he wondered whether a full-grown stallion had fit in there.

The abrupt gurgling of King Sombra’s stomach snapped Double Diamond out of his daydream. He jerked in surprise - and stifled a moan when the king’s royal scepter jumped inside of him in response.

Above his cock-happy servant, King Sombra yawned slightly. He’d never much enjoyed these court sessions. Didn’t really see the point in them, especially since he took an almost perverse glee in denying the nobles’ trite requests. Still...these sessions were always an excellent opportunity to show off his magnificent body before his court. No matter what, he could always count on feeling everyone’s eyes watching him, wishing, desiring, envying - but never having.

He shifted his weight and smiled softly as he felt his cock shifting inside of his little cockwarmer. Ah, yes. He’d almost forgotten. Truth be told, he’d put off acquiring an official one for far too long. How long had his poor stallionhood been cold and alone between his legs, with only the gurgling of his great gut to stimulate it? Too long - far too long for a king to tolerate. And it seemed that the little servant - Double Diamond, he remembered; he always made it a habit to know the names of the ponies serving him - was doing a better job than he’d expected. His tight, plush rear fit Sombra’s royal tool perfectly, and it was such a pleasant distraction from the boring propriety of the court.

In fact… Sombra’s smile widened into a sharp-toothed grin. There was something new in the eyes of his court - a new kind of envy, for more than just his massive, luscious body. He rested his arms on his gut, softly rubbing it as he pondered this new element. Perhaps they were envious of his new servant?

And well that they should be. Still, there wasn’t a chance that he’d allow cockwarmers to become the next big thing among the aristocracy. Such a privilege was reserved only for a king; just like with his weight, any pony who came even close to competing with him wound up only adding to the king’s wealth. Whether it be a wealth of fat or a wealth of fucktoys, Sombra cared little.

Still, though, even with the warmth and light entertainment provided by his new toy - he pumped his hips again, savoring the light moan that escaped Diamond’s lips - he found himself growing bored. And hungry. King Sombra never allowed himself to stay away from food for long. A figure this bountiful took hordes of calories to keep up, and even more calories to grow.

He beckoned to another servant, and not ten seconds later, a cart had been rolled up to his throne heavy with warm, steaming delicacies. The noble before his throne paused, staring at the cart in askance. Sombra made a small “go on” gesture, and the noble resumed his blathering plea. Meanwhile, Sombra busied himself with an extremely delicious looking leg of lamb.

Most ponies shied away from meat, but Sombra had always savored the taste. Rich juices dripped down his multiple chins before coming to rest in a small puddle between his breasts. He tore off another enormous mouthful and gulped it down, barely chewing, and only desiring to consume as much as he possibly could. The void in his belly was nearly always present these days, and a king as large as he had a debt to his crown to keep it filled.

On and on Sombra munched, gulping down enough food to feed a family of five, as the stallion at the foot of his throne just kept talking. It wasn’t hard for Sombra to keep that incessant idiot out of his mind, and even easier for him to focus on happier things - like the way his cock seemed to be hardening as he ate and ate and ate.

Beneath him, Double Diamond let out a small groan as the weight on his back increased. Sombra’s belly, which had already been of an enormous size, was slowly swelling around him, stretching around the vast feast that the king had seen fit to label a “snack.” Diamond’s burden increased moment by moment, King Sombra’s belly growing heavier and heavier as he chewed, gulped, and swallowed. Soon, the stretch in his ass was widening as well, Double Diamond letting out a small squeak as his king’s arousal made itself all the more apparent.

King Sombra had always been one to get excited over a full meal, and by the time his stallionhood had reached full mast inside of Double Diamond, he was bored, hungry, and horny. He held up a hand, motioning for his servants to pause in feeding him. As the noble’s soliloquy reached its end, the king rubbed and patted his belly, loving the feeling of tightness lingering beneath his flab. He amused himself by playing with his flab for a few moments, shaking and pushing his belly folds. It wasn’t long, though, before a familiar, rumbling feeling grew in his gurgling gut.

BRAAAAAAAP.

Sombra’s belch was a sound as powerful as his stomach, and its volume completely filled the room. On a good night, Sombra’s belching had been known to rattle windows and ruin manes; as it was, even in a wide-open room like this, more than one noble felt a sudden draft of hot, scented air rippling across their faces. Eyes widened all around the room, and the noble before the throne stopped talking midsentence.

Sombra burped again - this time, at only around half the volume - and groaned, massaging his gut gently. “Yes,” he said slowly, his big hands resting on his stomach. “Very good. The Empire thanks you for your request. The Queen will see to it that you’re taken care of.”

The noble’s eyes opened wide - the Queen? Sombra laughed inwardly. Oh, she would take good care of him indeed...for a certain value of good. If he made it out uneaten, he’d consider sending him a note of congratulations. But the noble knew that worse dangers awaited if he defied his king’s direct order, and so bowed low and backed away from the throne.

King Sombra made a waving gesture, and the next petitioner stepped forward. As she began to talk, Sombra sighed and leaned back in his throne, his belly jiggling greatly at impact.

At his king’s sigh, Double Diamond that he had to do something. A bored King Sombra was a dangerous King Sombra - and one that was unlikely to give him any sort of reward for a job well done. So, to keep his king from boredom, Diamond decided to try something new.

He began to clench and relax his asscheeks around his king’s member, working his hips around Sombra’s shaft with a steady, pumping rhythm. Sombra’s cock throbbed appreciatively, and Diamond bit down on his lip as he felt a sudden spurt of precum inside of him. His own cock was fully hard by now, and he could feel a fire burning inside of him as Sombra’s hips began to pump a little bit in response. He was doing it. It was working.

Above him, a thin smile spread across King Sombra’s face. So his little servant had some initiative in him, did he? Excellent. He so liked a servant like that. And if he could keep him entertained throughout the royal bore that the royal court so often was… That smile became a smirk. Then so much the better, both for him and for his King.

So Sombra began to thrust - not much, not as if in pleasure or “true” intercourse - but a little bit. Enough to make his massive gut wobble and ripple, and enough for Double Diamond to notice. Sombra’s smirked widened as he heard a small grunt of surprise from his little servant - “Ah,” Diamond groaned, Sombra’s medial ring spreading his ass wide. “Ooh.” He liked to feel full, did he? Well, Sombra could certainly oblige.

But first, he’d like to feel full as well. Still gently rolling his hips, Sombra beckoned for a pair of servants to approach him. The appetizer was over; the massive, groaning cart of food that the pair of stallions rolled over to him probably held enough to feed a third of the ponies in this room. Sombra’s stomach just rumbled loudly, and for a moment he forgot the pleasure encompassing his stallionhood, so great was his hunger. A crook of his finger set one of the servants to gathering enough food to begin the feeding; another twitch brought the second servant over to his enormous gut. Sombra had always enjoyed a good belly rub, and if he was to snack properly, then he’d like to feel pleasured all around his body while he did so.

And gods, but he was being pleasured all right. Sombra allowed his eyes to flutter closed for a moment, his chunky arms going up behind his head as he leaned back in his throne. The little Diamond stallion truly seemed to be getting into it. It seemed less that Sombra was fucking him and more that the servant’s ass was fucking his king’s cock - and Sombra had no problem with that. It was wrong for a king to expend his energy when a servant could do it just the same.

His belly jiggled gently as the speed of Diamond’s hips increased. Soon, Diamond was nearly bottoming out on Sombra’s cock, the king’s massive nuts slapping lightly against the smaller stallion’s rumps with each thrust. His belly was growing tighter and, soon, larger, as Sombra gulped down more and more food. He didn’t even care that the petitioner was still talking, so consumed in gluttony and lust was he. Soon, his belly was spilling over Double Diamond’s entire form, his gigantic gurgling gut rising so high that it nearly covered his face.

And still, Sombra ate on, consuming food even faster than his servant could feed it to him, and groaning in irritation while he waited for the next groaning platter to be served to him. Still, it was pleasurable enough to have his belly massaged, both above by the second servant and below by Double Diamond’s jerking hips. The other servant’s hands were doing a masterful job, squeezing and kneading Sombra’s gratuitous flesh in just the right way to ease digestion. His hands sunk deep into Sombra’s folds of fat and flab before slowly rising again.

Soon, Sombra felt a tightness building at the base of his cock. He didn’t even bother to try and hold it in, nor did he so much as pause in his feasting. His cock simply throbbed once inside of Double Diamond’s ass - bulging and spreading him wider than ever before - and then rope after rope of thick, white cum was flooding into Diamond’s ass. To his credit, Sombra noted approvingly between bites of mutton, the little stallion held in his groans of pleasure, even when his belly began to round out with the force and volume of Sombra’s cum.

After a good minute or so, Sombra’s orgasm tapered off. He took a moment to swallow the last bite of his snack, groaned softly, and signalled his Vizier, who was standing off to the side of the throne. Everyone in the chamber knew what that meant: the royal court was over. The petitioner, still not finished with her plea, sullenly followed the crowd as it flooded out of the room.

Sombra dismissed the two standing servants with nod of his head. It was a shame to lose the belly massage, though, especially now that he was finally feeling so wonderfully full. Perhaps he ought to invest in a professional belly-rubber, to keep his enormous gut happy and soft at all hours of the day.

But there was another member of his household to deal with first. Sombra grinned as he grabbed his belly with both hands - neither succeeding in reaching more than a quarter of the way around - and said, “Up.”

He frowned when a few seconds passed and no response was made. “I said, Royal Cockwarmer, up.”

With a jerking, twitching motion, Double Diamond scrambled to his feet. Sombra’s gut - the king silently marvelled at the ease with which his little cocksleeve had lifted such a weight - flopped back down against the king’s legs with a mighty smack, his softening cock falling between his legs as it left Diamond’s ass with a schlick.

“My apologies, your majesty.” Double Diamond stood straight and tall, though his eyes were pointed directly at the floor. Again approvingly, Sombra noted that his own cock was both erect and perfectly dry. Good.

“You are forgiven.” Never let it be said that Sombra was not a magnanimous ruler. “Approach.”

Eyes still pointed downward, Double Diamond walked until he’d resume the same position beside the throne that he had occupied before court had begun.

“You did well,” Sombra said. He reached out and took a hold of Diamond’s cock, beginning to gently stroke it up and down. “An excellent first day, I would say.”

Diamond’s cheeks flushed, but there was an undeniable flash of pride on his face. “Thank you, your majesty.”

Sombra inclined his head. “Yes, very good. You hold my cock well. And my seed even better.” He patted Diamond’s bulging belly, which was swollen with Sombra’s cum. It wasn’t quite as large as it could have been - Sombra had had bigger orgasms - but it was a good-sized gut. It squished underneath Sombra’s fingers, gurgling happily. And it was a start.

“Starting today, you will no longer dine in the servants’ quarters,” Sombra said. Diamond’s eyes widened imperceptibly. “Instead, you will subsist on a diet consisting of royal seed alone. Mostly mine, of course, though I may occasionally lend you out to the Queen if she requests it.

“Soon,” he said, giving Diamond’s cum-filled, sloshing belly another pat, “we’ll have you big enough to be a proper servant of the royal household. A skinny servant is a terrible thing.”

Sombra eyed his trembling servant. “What say you?”

“Thank you, my king,” Diamond said. He licked his lips, his boner throbbing beneath Sombra’s fingertips. Sombra grinned and went on.

“You’ve done a masterful job, in any case,” he said. “I must say, I was surprised at your aptitude at holding my cock and cum alike. So I have decided, on a whim, to grant you one request. Not necessarily to be fulfilled today, nor tomorrow, but at a time of my own choosing.”

His smile was teasing, knowing. “What say you?” he said again.

“Nothing,” Double DIamond said quickly - too quickly. “Your pleasure, my king, is its own - “

“Lies.” Sombra shook his head sadly. “My dear Diamond, I asked you to tell me the truth. Would you deceive your king?”

Diamond swallowed, his cheeks pale. “N-no. Your majesty.”

“Good. Now look at me and tell me what you desire.”

Trembling, Double Diamond and met Sombra’s gaze. When he spoke, it was like a whisper. “I would have myself pleasure my king,” he said softly. “And I would do it, if it pleases your majesty, while looking into your eyes.”

Sombra’s smile was positively predatory. “You would be a royal concubine?” Diamond nodded slowly. “Fear not. It is a good thing to desire. But you must prove your worth as my cockwarmer first - and do not believe for an instant that I may allow to you retire. Your skills have already proven too valuable to lose.”

Double Diamond was already nodding, tripping over his own words. “Y-yes, my king. Anything. I will continue - “

“I’m sure you will.” Sombra’s fangs poked out over his lips as he gave Diamond’s throbbing dick one last little pat with his fat, sausage-thick fingers. “Because a good cockwarmer is hard to find. A good cockwarmer who holds back his orgasm until he’s told? Near impossible.”

Double Diamond smiled weakly.

“You’ll have your orgasm,” Sombra said.. “In time. Perhaps even tonight. But for now, it is time for dinner - and I would not want my poor stallionhood to be cold while my belly is warm and full. Will you accompany me to my quarters?”

Double Diamond couldn’t say yes fast enough.
