Sweet Relief

"Look at you..." Celestia giggled, sliding a hand over Dusk's stomach as he straightened out on the enormous bed he rested on. "All tied up in knots, aren't you?"

"Yeah..." the stallion sighed, cracking his neck with a shift of his skull and trying his best to unwind.

"When was the last time you slept?" she asked, using her magic to dissipate his expensive clothing into golden sparks, exposing his toned, slender form to her watching eye. "Or should I say, when was the last time you slept properly?"

"Is that a trick question?" Dusk scoffed, staring up at the ceiling as Celestia planted a soft, warm kiss on his groin, just north of his length. "Proper sleep doesn't come around my room anymore."

"To be expected," the former monarch nodded, her thick mane shifting and tumbling over her shoulder as she did so. "It's only recently it seems to have found its way into mine once again."

The setting sun cast a long, warm hue over the room they found themselves in. Tones of orange setting a relaxed, ambient atmosphere as light cascaded through the thin curtains Celestia had hung around her abode. Soon it would be night, and both of them would separate once again. But Dusk, the newly-crowned monarch, had a rough few weeks. Ceremony after ceremony, signature after signature, appearance after appearance. All of it had worn down on the stallion and it was clear his mind, body, and soul were in disarray, something that Celestia had summoned him here to fix by her own hand.

Or, by her own mouth, as it were. She kissed the same spot affectionately once more, long and slow, eyes closing as she did so. The stallion beneath her returned the gesture, exhaling a full breath through his nostrils over several long moments. The years she'd spent around him told her exactly what mood he was in and how to fix it, and that long breath was a tell. It was a tick that told her he was at the door of proper relaxation, and all she need do is beckon him inside.

And she set to doing just that. With a soft, experienced hand, Celestia caressed the younger Alicorn's length, feeling it twitch and blossom at her touch. A small smile pursed her lips, pride swelling just the smallest amount at knowing such a small gesture could gain such a reaction from Dusk.

"Still some life in the old bones, hm?" the ancient Alicorn chuckled, running her hand up the entire length of Dusk's already-impressive shaft as she felt it harden between her fingers.

"Here and there," he passively shrugged, head lolling to the side as the tiredness overtook him once again.

"Am I failing to entertain you, little one?" Celestia smirked, gently pressing a thumb into Dusk's thigh to prevent him from drifting off.

"Don't even begin to pretend you don't know exactly how I'm feeling right now," the stallion cackled, eyes cracking open for a brief moment and really displaying how utterly exhausted he was. "You dealt with this for over a millennia. You know."

"Yes, yes, that is indeed true," Celestia nodded along, her own experiences with such tiredness being enough to fill a novel. "Take whatever rest you need."

With that, the stallion's eyes closed and his posture shifted once again, clearly getting comfortable on the bed. Celestia rolled her own magenta orbs at the situation before setting to work on her own task. The stallion was finally erect, his length standing at a truly titanic size that a mare any smaller than her would have trouble accommodating. Whether in hand mouth, or anywhere else, Celestia gave a quick prayer of thanks to her own impressive size that she had what it took to handle the beast between her fingers.

With a deep breath and an eager glint in her eye, she set herself to work. The cover of her mouth locked around the twitching tip of Dusk's cock, the stallion exhaling through his teeth in response to the sensation, and Celestia continued to spear herself on it. Her tongue was her greatest ally in her attempts, licking circles around his shaft, using her thick saliva to lubricate the pillar in her maw. Over and over again her powerful oral muscle circled, swallowed, and suckled against the twitching cock in her mouth, soaking inch after inch with spit and effort.

Even a mare of her size and experience struggled to fit something in her maw, feeling her throat bulge and stretch, the sensation of such a titanic length in her throat sending a shiver of excitement down her spine. Inhaling through her nostrils was all she could do, her maw completely sealed by the size of the cock she eagerly gulped down.

Dusk twitched once again, the powerful heart the stallion possessed pumping more blood into his length and causing it to flare up even thicker. Celestia placed both hands at the base of his shaft, cupping his cock in the gap between her fingers as she plunged herself even further down onto it. Eventually, with a guttural grunt and a moan of satisfaction from her stallion, she sheathed the entirety of it in her throat.

She'd done this more times than she could count, both with Dusk and with countless other stallions over the years, and yet the sense of satisfaction and pride at managing to overcome such a challenge never faded. She could feel his cock almost hitting the top of her stomach, her entire throat being used and pushed to the brink to house something so massive.

Dusk cracked his eyes open to view the sight before him, seeing and feeling Celestia's tongue swirl around the base of his twitching prick, and catching a playful wink from his mentor as she pulled herself back off his cock. Now that he was properly lubricated, Celestia set to work on his prick wherever she felt like. Her hands, soft and experienced, massaged his balls, rolling and caressing the baseball-sized testicles kept hidden inside his sack, all while her mouth sucked and lapped at the base of his length.

She soon danced her tongue up from base to tip, years of experience working with cocks of all sizes having taught the marvellous mare exactly what and where she needed to press. Keep the tongue flat, keep the cock wet, make sure you don't ignore anywhere for too long, keep those hands busy. All a checklist ingrained into her memory from all those hundreds of years in the bedroom, funnelled through her maw and directly onto Dusk's cock.

She swallowed the tip again, moaning down the length of his shaft and sending tremors down to the base. Dusk groaned loudly, a vocal wave of approval from her man of the moment, seeing him shift and dig his fingers into the bedsheets.

"Look at you... purring like a kitten," Celestia chuckled, sliding down and kissing his balls while her hands worked the tip of his cock. "Do you love when I do this? Does being the centre of my everything make you happy?"

He nodded quietly, eyes cracking open once more and smiling at her as he opened his legs a little wider, letting the much-larger mare get better access to his cock. Celestia set to work with old faithful at this point, locking her lips around the tip of his cock and bombing her head up and down the first nine inches of meat. Dusk's toes curled and fingers dug deeper into the bed, pre beginning to leak from his throbbing tip as Celestia's excellent service brought him closer and closer to the edge.

Sweat began to bead along her body, cropping up under her snow-white coat as the exertion got to her. She had to admit, in recent years she hadn't kept up with her exercise as much as she should. And by 'recent years', she meant the last four or five centuries. There was once a point where, much like her sister, the Eternal Sun of Equestria, was the pinnacle of fitness. Strong, toned, and in unbelievable shape, she could once perform physical feats without the use of her magic that would leave others in awe.

But soon a busier schedule took over, which lead to exhaustion. Exhaustion leads to complacency, complacency leads to laziness, and laziness leads to a lack of upkeep. So what was once a temple of muscle and commitment soon devolved into an eatery of sweet treats and lazy weekends whenever she could get away with it.

While her monarch duties and new retirement hadn't called for much physical strain, foreplay and sex always took the wind out of her sails in a way it never used to. Furrowing her brow and sucking in a deep breath through her nose, she set to work once more as best she could with her tired, strained neck. If it didn't already push her to her limits from having a cock the size of a foreleg in her gullet, the exertion of such rigorous fellatio was definitely going to make her sore in the morning.

But, as evidence by the effort she put into swallowing the throbbing prick of the stallion that meant the most to her, it wasn't about how she felt. It was all about him and what she could do to make him feel better. And she knew better than anyone, what she could do was work his fat cock until he popped like a champagne bottle. So with renewed vigour, passion, and effort, Celestia set to work blowing that stallion's mind with oral skill most mares couldn't dream of achieving.

His cock was drenched with spit. That alone made it so much easier for her hands and mouth to work every single throbbing inch of it. His balls were also covered, allowing her to roll them around in her palms and between her fingers without any resistance or effort. All she had to do was keep that cock wet with her performance and Dusk would be blowing his load into her maw before she knew it.

And 'before she knew it', seemed to be even sooner than she thought. The stallion had tells for when he was going to cum, and while grabbing her head and ramming their cock down her throat was a tell for a lot of stallions, Dusk was never the type. His was a short, quiet whinny. One of the most adorable sounds she'd ever heard a creature make, higher-pitched than any sound the stallion usually squeaked out, and one she loved hearing.

Her fur-tipped ears twitched as she heard it once more, knowing full-well what that meant and how she was going to handle it. The response, as always, was vigorous exertion. She bombed her mouth up and down the entire length of his cock, taking every single inch into her gullet over and over again, able to see the channel of her throat physically flexing as she did so. It was tight, wet, and oh-so skilled, and that was something Dusk could never handled.

A hand, gentle and caring, was placed on top of Celestia's head as the stallion got closer and closer to popping. He affectionately toyed with Celestia's mane, twisting and curling loops and strands around his fingers whilst gently stroking her scalp. It sent a little shiver down her spine, the stallion always finding just the right spot to caress her in to really make it feel good.

Sucking his cock down over and over again, feeling that tip hit just before her stomach, pushing it closer and closer to the edge before finally...

Dusk whinnied loudly, gritting his teeth and blowing his load deep into Celestia's stomach. The feeling of his torrential orgasm hitting her stomach could be seen on the outside of it, the mare twitching and shivering in pleasure as his load continued to fill her. Pulling back with a loud, wet pop, the gushing tip of Dusk's cock fell from her mouth and continued to blow a hearty load all over her.

Extending her tongue and closing her eyes, Celestia felt the rain of cum coat her face, mouth, tits, and stomach, all the while the stallion grunted and groaned all the way through his orgasm. Soon that torrent came to an end, the last few spurts falling weakly onto the bedsheets, leaving Dusk and Celestia both panting in unison as they locked eyes once again.

"You're always one for the big finishes, aren't you?" she giggled.

"Such a performance always deserves a shower of praise, wouldn't you agree?" the stallion responded with a tired smirk.

"Mhm, that I would, my dear," Celestia nodded, looking down at her cum-soaked appearance and sighing quietly. "This is going to take such a long time to wash off."

"Sorry," Dusk smiled sheepishly.

"No, no, don't apologise," Celestia said, gently rubbing Dusk's thigh with a soft hand. "It's always a treat in the moment, regardless of how long it takes to clean up afterwards. And with that out of the way... I shall leave you to your rest, Your Majesty."

"Thanks, Celestia," Dusk nodded. "The Crown appreciates your generous service."

"You're telling me," she nodded, getting to her feet and heading to the attached bathroom to begin the quest of cleaning.

Showery Seconds

The sound of the warm, clean water splashing off Celestia's buxom body echoed throughout the bathroom. The room radiated expensive design, from its polished tiles to its gilded fittings, there'd been no expense spared at its construction.

The former matriarch's hands lathered her buxom body with soap, running over every inch of her beautiful body, from her wide birthing hips, to her enormous breasts, to her colossal ass. The suds rinsed the sweat and stain of sexual service from her body, and a relaxed sigh fell from between her plump lips as the strain of a busy day washed away with it.

Until her attention was grabbed by the sensation of arms wrapping around her slender waist followed by the feeling of something hot, hard, and heavy sliding up over her ass. A faint smile touched her lips at the feeling, knowing exactly who it was and exactly what they wanted without a word needing to be uttered between either of them.

"I thought you were taking a nap, Your Highness," Celestia cooed playfully, glancing over her shoulder and just making out the horn tip of the aforementioned royal.

"Not done yet," came the guttural grunt of a response, the cock against her ass twitching desperately. "I wanna fuck your pussy."

"My, my, such a forward request," she giggled, a hand over her mouth in faux shock. "Has the tiredness sapped all your manners, my sweet little thing?"

"Celestia..." Dusk moaned, again grinding himself against her soap-soaked ass, precum leaking out from the throbbing tip of his cock and onto her lower back.

"Such a needy little one, aren't you?" she teased. "Very well, your wish is my command, and my body is your plaything, after all."

"Bend over," the smaller Alicorn ordered, no hint of politeness in his tone whatsoever.

Celestia did as he so commanded, leaning herself against the wall and spreading her thick legs nice and far apart. The stallion grabbed the base of her tail and pulled its soaked plumage aside, his hungry gaze focusing on the solar Alicorn's gorgeous, plump pussy and her twitching asshole. As brief as their contact had been and as quick as her orders had been given, Dusk could see she was wet from a whole other kind of liquid.

With his free hand, he threw a mighty slap across her ass, his palm colliding loudly with the cutie mark emblazoned across her enormous rear. The thick flesh rippled on impact, all of the weight of her fat asscheek shifting and jiggling from one singular strike. Celestia cast a gaze back at him, the two making eye contact for a short moment before she winked playfully, eagerly edging him onwards.

He rewarded her willingness with another slap. This one harder and firmer, slapping deep into her massive ass and grabbing a handful of it. His fingers squeezed around it, the near-eight foot Alicorn shaking her colossal ass in response to such eager kneading from the Equestrian Monarch.

"Playing with your food, are you?" Celestia smirked. "I thought you were hungry... why not dig in already?"

"Shake it," Dusk responded. "Shake your ass for me."

"Making me do such unsightly things, aren't you?" came the response, rolling her eyes before obeying his command. "What would the common folk of our beautiful nation think if they saw their King up to such depraved acts?"

"They'd be jealous of the fact they didn't get to stuff their cock into the fattest ass in Equestria," Dusk smirked, his sleepiness giving sway to a horny arrogance Celestia only ever saw on his face in moments such as these.

"Well then what are you waiting for, little one?" Celestia taunted. "Aren't you going to exercise your rights?"

Dusk didn't respond vocally. Instead, with a trained expertise and a gifted swiftness, he placed the head of his cock against the wet lips of Celestia's fat pussy and rammed himself as deep as he could go. The colossal size of his twitching prick stretched her insides out far and wide. Like an uppercut to the stomach, his cock bulged several inches out in front of her, ramming past her cervix and directly into her wet, waiting womb.

"A-Ah..." Celestia panted, shivering from head to toe already. "So... so rough... and so strong for something so... small and cute..."

Dusk pursed his lips at the comment, ears pricking up at the mention of the word 'small', viewing it as an affront to his power.

"I don't like what you just said, Celestia," he huffed, nostrils flaring as he spoke.

"Oh, I'm sorry, my King... I've been bad, haven't I?" she cooed back, putting on a meek and afraid voice as she batted her soaked eyelashes at him. "Are you and your big, fat cock gonna punish me?"

The stallion wasted no time answering that question. His hands slid over the wet flesh of Celestia's massive ass, the weight of her backside shifting against his touch before gripping tight against her slender waist. His fingers locked into place, anticipation and excitement causing every inch of his body from the tip of his muzzle to the head of his throbbing cock to shake.

Celestia bit her lip, ready to receive her favourite part of such willing service. Without a word between either of them, the fun began. Dusk's wide, girlish hips unleashed their full strength. Power the likes of which one would never expect from such a slender, waifish frame launched Celestia forward. Her face pressed into the wall, tongue lolling from her mouth as she felt every single colossal inch renovate her insides.

She giggled quietly, the sound drowned out by the mix of the spraying water and the thunderous claps of the stallion's hips against her mountainous ass. Her toes curled and her cunt clenched, clamping down hard on all those thick inches inside her, stroking and welcoming them in as the stallion slammed his hips back and forth over and over again.

Dusk soon leaned over onto his former teacher, resting the small weight of his short frame on the much larger Alicorn, allowing her thick, powerful thighs to support both of them. Powerful thrusts turned into long, scooping grinds. Pre-cum bubbled and spurted from the tip of Dusk's twitching prick, dousing the desperate heat in Celestia's womb.

The Alicorn, so virile and so plentiful, poured more inside her with his unwavering excitement than most other species would produce in ten orgasms. Celestia could feel it pooling inside her, the hunger and need for more and more of it growing within her every second that went by with every gentle grind against her wet cove.

"Is this what you needed, little one?" Celestia asked back over her shoulder, sweat mixing with the clean water of the shower. "This tight pussy make it all feel better?"

The response as another hard slap, bouncing her now palm-print stained rear on impact and gaining another playful giggle from Celestia.

"You're so rough when you're cranky," she smirked. "I like it."

"Then you're gonna like this even more," Dusk growled, returning to his previous standing position and properly heaving himself into action.

He was indeed correct, as he often was. Celestia very much did enjoy what she gave him, hearing the thunderous claps of his powerful hips against her colossal ass even above the din of the shower. The elder Alicorn's toes curled underneath her once more, her pudgy stomach flexing and clenching to accomodate her favourite stallion's favourite part, pooling more and more pre inside her cove as his pleasure soared higher and higher.

Dusk gritted his teeth as he crossed over the final line, slamming his broad hips home and locking his cock inside Celestia's desperate cove. Orgasm rocked the both of them, with Celestia clamping down as Dusk fired off thick jets of cum into her boiling insides. The stallion groaned as the mare squealed in pleasure, cum in volumes enough to fill barrels bloating her innards and stretching her stomach out futher and further.

Celestia touched a palm against her stomach, feeling it touch the floor as she continued to balloon bigger and bigger from her former-students seemingly-unending load. She giggled and gasped the entire way through the orgasm, feeling lightning and love crackle across her entire body as she continued to swell. The sound of cum sloshing and gurling inside her ungodly-gravid-looking stomach was like the sweetest music to her flicking ears.

But, sadly, all good things must come to an end, and soon the stallion's flexing balls emptied all their worth inside her, and his monstrous cock uncorked the wineskin he'd made her womb into. Cum, thick and heavy, poured out of the mare's well-fucked gunt, thick as porridge and hot as the water swirling and mixing with it on the shower floor.

The stallion rested his rapidly-softening cock against his lover's ass, rubbing his length against her and feeling the cum pour out across his fat, empty balls as he did so. Breathing soon returned to normal as the heaving of chests was soon replaced with quiet, gentle gasps as a sense of normalcy replaced the sexual ephoria.

Celestia stood up straight, turning around without a word and embraced the smaller stallion, standing several heads taller than him and pressing his own against her ample tits. Dusk began to suckle against her breast, magic-induced lactation granting him a gift of sweet, sugary milk with every suck of Celestia's large nipples.

"There we go, my spoiled little child..." Celestia chuckled quietly, gently stroking the back of Dusk's head as he pressed himself tighter against her enormous body. "Did you get it all out of your system finally?"

He nodded silently, continuing to drink down her milk without a care in the world. All sense of anxiety, worry, and stress drained away like his cum down the plughole, leaving the two of them sated, relaxed, and ready to dry off and tuck back into bed as soon as the slender little Alicorn finished his drink.

"I want your ass next," he muttered into her tit.

"Later, my sweet..." she said with a shake of her head. "I promise you that."

Truly Insatiable

The extra session in the shower nor the relaxing soak had calmed down the id of the stallion. Celestia had smirked to herself the moment she felt his eager hands on her body once again, feeling his strong fingers dig into her titantic tit-flesh with more desire than ever. She rolled over in the monarch's bed, allowing him to lie flat against her pudgy stomach while his hands massaged her breasts, and his tongue found hers.

His cock twitched against her torso, feeling it grow once again to it's enormous size pinned between the two of them. Whether on instinct or command, Dusk began grinding himself against her warm body. Beads of precum soon dripping from the tip of his stallionhood, staining her oh-so-recently-cleaned fur with an arousing stain and a lustful scent. She allowed her favourite stallion to simply use her as his toy at this point. Her favourite part of the process was, as always, his fascination with her mouth.

She felt his breath against her maw, panting with a mix of desire and a heavier mix of desperation. She stuck her tongue out in just the way he liked, allowing him to lap the flat of his own against hers. He shifted position on her body, sitting up, scooting forward, sliding his twitching prick between her colossal tits. The beat of their hearts almost synchronising through such carnal contact was almost romantic to the ancient Alicorn. She began to rub her tongue back against his at this point, feeling his heart beat accelerate through his cock as his excitement rose more and more.

Without a word, she could sense what he wanted. She'd been through this little ceremony with him so many times that she could tell where he wanted to cum on her just from the way his body shook. So she gave him what he wanted: her tits pressed nice and tight against that fat cock of his. He groaned the moment she applied pressure, his body running on a sinful autopilot, jerking his hips forward and feeling the heat of those fat, pillowy tits against his cock.

The process got hot and sweaty in a matter of moments. Her size, his excitement, their proximity, the bedsheets. All of it acting as ingredients in their sexual stew to create a temperature and a scent of carnal arrogance that only served to egg the two on further.

"I love your cock, Your Majesty..." Celestia moaned out in a teasing tone. "It's one of my favourite things in this world, you know?"

"C-Celestia..." Dusk grunted, the vocal adoration clearly acting as yet another uppercut to his lust-addled mind.

"I love the way it feels inside me," she purred, using her tits to stroke against his length in a trained fashion. "The fact it feels like it's in my skull the way you ram it in my hot pussy... the way it feels like it's going to split me in two if you go just a little bit faster..."

He jerked his cock forward more aggressively inside her cleavage, the head of his desperate length poking out from between her mountainous breasts. Celestia took the hint without wasting a moment, wrapping her thick lips around the precum-slicked head of her favourite toy and moaning quietly as she sucked.

"Ah..." Dusk grunted, cupping a hand around the outside of Celestia's as she held her breasts in place.

A romantic gesture slipping through the haze in the stallion's mind, and one that brought a smile to the face of the much-larger Alicorn.

"I really love you, you know?" Celestia continued to tease. "I'm so happy that you're a part of my life, and I'd trade the world just to stay with you like this forever."

"I..." the stallion began, clearly struggling to hold back an orgasm as his former-teacher continued to lather him with adoration. "I love you too."

"We should do this for the rest of the night," Celestia spoke, gently suckling the tip of Dusk's cock between sentences. "We should keep having sex until it's time for the sun to rise."

"I'd really like that..." the stallion muttered.

"I want you inside me again, Your Majesty," she cooed, picking up the pace with her tits and coaxing the stallion to a messy end. "I want to feel your fat cock fill me to the brim over and over again. There's nothing in this world I love more than seeing your eyes flutter and your ears twitch as you blow your load in my pussy."

That was all it took to get him over the edge again. Dusk locked up, slamming the head of his cock into the back of Celestia's mouth as he came. His thick, girlish thighs convulsed and twitched as he came, his thick, white seed audibly splashing in the whiter Alicorn's gullet as she eagerly gulped down every mouthful of it. She moved her hands from his tits to his hips, allowing her breasts to fall away from their vice-like lock on his cock and forcing more of it down her throat.

She moaned the entire time, sucking, gulping, and rolling her tongue all over his sweat-slicked stallionhood, gorging herself on the salty taste and beautiful texture of his thick prick against her lips and inside her mouth. She felt his gift pooling in her stomach, beginning to stretch out her-already hefty belly a few more sizes.

The effeminate stallion soon emptied his reserves, finishing with his tongue lolling from his mouth, sweat coating every inch of him, an electric shivers of sexual bliss sparking through him every few seconds. He was panting heavily, almost as heavily as Celestia was. The mare grinned with almost sinister intent, suddenly springing up from the bed and pinning Dusk underneath her.

She kissed him once again, this time driving her much-larger tongue deep into his maw, touching the back of his gullet and almost making him swallow it. Dusk didn't attempt to regain control of the engagement, content to simply lie back and allow Celestia to service his mouth with her own. Instead, he slipped his cock, still throbbing and coated with quite the concoction of spit, sweat, and cum, between her breasts and gently grinding against them again.

They remained coiled together like this for who knew how long. Minutes, hours, days, neither could tell. Losing time in one another's warm, loving embrace became the only thing that kept the stallion sane after the stress and pain of running a nation. Without Celestia, he'd have gone insane long ago. Outside the bedroom, she offered advice, solutions, and ideas he'd never have even considered until it was several days too late.

Inside the bedroom, she drained him of every sinful thought he'd ever had and allowed him to truly relieve himself in ways neither sleep, food, nor partying could ever come close to. Her mouth, her tits, her pussy, all in service to the crown whenever he desired. All his and his alone. But he'd forgotten one thing in that list, and it was that one thing he was desperate for.

Her ass.

He tapped Celestia twice on the ribs, their signal to break apart and speak for however long they could manage before the desire overtook them again.

"Yes, My Lord?" Celestia asked as she broke away from him.

"Your ass," he commanded without a hint of courtesy to it. "Get on your knees and spread your ass."

"Of course, Your Majesty," she nodded, doing as ordered without a moment's hesitation.

Her buxom, lumbering body did as he requested. Pivoting away from him and crawling to a more open space on the bed. Collapsing onto her front with her titanic rear raised high in the air, she reached back and spread her enormous cheeks open with both hands, exposing the sexual treasure hidden between them. Dusk wasted no time assuming his position behind her.

Celestia's ass alone was nearly twice the size of his torso. Her hips, so wide and full, were something he struggled to get his arms around even if he stretched. If she'd let go of her cheeks and allow them to fall, the noise they'd make colliding with each other would be audible outside the room.

The twinky little Alicorn wasted no time once he was in position. His hands dug into the thick flesh of Celestia's huge rear, nearly losing them in the process, before he drove his face directly into her sweat-slicked cove. The Solar Alicorn bit down on her lip, groaning in satisfaction as she felt Dusk's thick, wet tongue lapping against her tight asshole.

"Mhmhmmm..." she giggled, gently shaking her ass back against his face, sticking the tip of her tongue out as she did. "My Lord's finally decided to indulge in his favourite snack, has he?"

The muffled groan of content Dusk shot back, barely audible outside the cavernous expanse of Celestia's asscheeks, was all she needed to hear. The stallion in question had rammed his muzzle so deep against Celestia's ass that he risked losing it. Huffing, licking, and nibbling her asshole inbetween heavy pants and trembles of excitement.

Celestia giggled contentedly to herself, watching such a sophisticated stallion almost lose himself in a lust so primal that she rarely saw it outside of these bedroom antics with her favourite student. She soon felt his tongue slip inside her asshole, pushing past her tight ring and deep into her cavern.

"Ooooh..." the moan escaping through her lips sounded. "Oh, my favourite part..."

Dusk obliged her more and more, continuing to gorge himself on her asshole, both of them panting and gasping through a near-visible cloud of lust and desire. Celestia's beautiful asshole was slathered and soaked with spit and sweat by the time Dusk was finished, Celestia nearly whining like an upset dog when she finally felt his tongue retract from her hole. Though like any well-trained dog, she knew what treat was about to come next for her good behaviour, and if she could to begin with, her tail would've been wagging up a storm.

She felt Dusk press the head of his enormous cock against her asshole. Precum dripping from the tip mixing with the spit and sweat coating her ass making for such a beautiful texture. She could feel his heartbeat against her entrance, just the same as he could feel the heat of her insides radiating down his entire length as he held himself there. Celestia looked back over her shoulder, locking eyes with her sweaty and sex-crazed stallion before winking playfully at him.

That little exchange was all he needed, and soon Celestia felt herself moaning in bliss as he pushed himself past her asshole and deep inside her. She gritted her teeth instinctively, adoring the feeling of straining to take fifteen entire inches of a cock so thick it felt like a forearm being stuffed into her guts.

"I love you!" she crowed. "I love you in my ass!"

Dusk didn't answer vocally, instead slapping her across one of her enormous asscheeks with enough force to stain it red within seconds. The white Alicorn lurched forward in surprise, moans escaping her slutty little mouth as the sting of pain mixed with the pleasure of being used.

"Mhmhmmm..." she moaned. "Do it again, My Lord. Please..."

He obliged immediately, striking her again and getting a pleasured, playful shake of her ass in response. He soon hilted himself in his prize slut's asshole, his enormous balls resting against the lips of her wet cunt and feeling the heat of it all wash over him. Celestia managed to get her breathing back under control, struggling to keep her faculties together when filled with a cock so huge it felt like every minor twitch it made caused it to balloon in size inside her.

"Yes... yes, My Lord," Celestia cooed playfully, cheeks flush with sexual euphoria as she gently shook her ass against his cock again. "Give it to me properly, please. I will beg if you need me to."

"Then beg me," he ordered smugly.

"Please, My Lord, give your whore what she desires!" Celestia cried out, wasting no time getting into the command. "This ass was built for your cock and your cock alone! There's nothing in my life that I want more than to feel your fat, twitching cock cum inside my gigantic, slutty ass! I live to serve you, My Lord, and I'd rather die than go another second without feeling your perfect dick stretch my worthless asshole!"

"Good girl," Dusk smirked, affectionately stroking the sun mark on her flanks. "And good girls get treats..."

"Please, My Lord," Celestia nodded eagerly, lowering herself onto her tits once more and preparing to be fucked into the bedframe.

And so Dusk gave her exactly what they both wanted. He switched his grip up, grabbing hold of those wide birthing hips as best he could and slipping into a higher gear. He gritted his teeth at the exact moment the first groan fell from Celestia's lips, feeling the tightness of her insides clench against his enormous cock as he stirred up the ancient Alicorn's guts. Dusk could feel his body preparing itself for another orgasm, but he made an effort to fight off the feeling for as long as he could.

He wanted to lose himself in Celestia's ass, regardless of his biological clock urging him to cum. He could feel that oven-like warmth radiating through his cock, feel his fat balls filling up with seed yet again as they slapped against her wet cunt. His hands couldn't keep themselves in one place, toying with the ample flesh of Celestia's mountainous ass, watching all of that flesh move, shake, and tremble as he hammered himself in and out of her over and over again.

The bed, so sturdy and resilient, began creaking as it struggled to handle the weight of the Solar Alicorn getting shifted by such a hard fucking. Every inch of Celestia's body seemed to jiggle, that perfect, motherly body weight that made her so buxon and soft bouncing back and forth as Dusk had his way with her body. He flashed back to long ago, thinking about the first time he'd ever kissed Celestia. How he'd trembled with fear and nervousness as he'd asked her to take their relationship to a more romantic and intimate level. How he'd been so stricken with anxiety that Celestia had to take over and control the kiss herself, using her hands to steady him and her body to press against his own and try to calm him down.

And now look at where they were, all these years later. Bedframes almost broken, holes fucked into walls, and every single inch of Celestia's body being dedicated to serving his every sexual desire with nothing more than a snap of his finger. He loved Celestia. He loved her mouth, her pussy, her tits, her ass. Every inch of her mind, body, and soul was beautiful, and every inch of her mind, body, and soul belonged to him.

He gritted his teeth once more, finding his trip down memory lane to how he'd claimed ownership of his favourite mare had pushed him too close to the brink of orgasm. Barely clinging on, watching Celestia's ass bounce, her tongue loll from her mouth, and her eyes nearly rolled back into her skull, he tried to distract himself with any other thoughts. Thankfully, a knock came at the chamber door. A specific one, a coded one made to let him know who it was and that their presence was somewhat urgent.

"Enter, Luna," Dusk called out.

The door swung open and in walked the Princess of the Moon, dressed in her usual ensemble of blue cloths and black leathers, carrying the appearance and stature of a soldier, a role she had willingly fallen back into once she'd given up her position on the throne. Her eyes found the scene in the room, watching the svelte Alicorn dominating her older sister, yet her familiarity with the concept and her professionalism keeping her in line.

"Your Majesty," she began, standing at attention and maintaining eye contact with Dusk. "There is a member of the Saddle Arabian Embassy here requesting Celestia's presence."

"For what purpose?" Dusk asked, still on the verge of cumming his soul out into Celestia's titantic ass.

"They wouldn't state it explicitly, however they made mention that the issue was something Celestia would want to oversee herself," Luna answered. "Something about a 'golden lake'."

The term sparked recognition in Celestia's ass, an almost a sense of worry on her face.

"Dusk, I know we're in the middle of something, but this is extremely urgent," Celestia mentioned, breaking character and turning to face Dusk.

"Right," he nodded, withdrawing himself from Celestia's insides and dropping onto the side of the bed.

The Solar Alicorn regained her composure immediately, using magic, perfume, and years of experience to appear as if she hadn't been on the receiving end of several hours of rough sex. With an apology and a kiss, she bade farewell to Dusk and promised to return as soon as she could to finish their time together.

The door closed quickly after she exited the room, leaving Luna and Dusk in somewhat of an awkward space. There he was, cock still throbbing and coated with sexual juices strong enough to intoxicate an entire room of ponies, unsatisfied and somewhat irked about the interruption. He prepared himself to clean up and resume attempting to sleep, only for Luna to interrupt his thoughts.

"My Lord," she said in a hushed tone, getting down onto her knees in front of him and gingerly reaching a hand towards his cock. "May I?"

There was a long moment of silence between the two of them, this being something that hadn't entered their relationship beforehand, yet it was clear from the blazing look of desire in Luna's eyes that she wanted this more than he did.

"Of course," he nodded, leaning back on his hands and allowing Luna to work.

And work she did. Without a moment's hesitation or reluctance, she leaned forward and hilted his cock in her throat. Dusk groaned in pleasure, but also heavily in surprise. His cock had filled the gullet of many a mare before in his life, yet the sensations he felt from Luna's were like nothing he'd ever experienced.

Her entire body was cool. Like fresh springwater on a hot summer's day, so different from the blazing temperatures of Celestia's insides. He gritted his teeth at the feeling, watching Luna's plump blue lips work magic on his dick as she bobbed her head up and down his length.

"Do you like the taste of my cock?" Dusk asked.

She nodded quickly.

"Do you like the taste of your sister's ass?" came the second question.

Luna hesitated for a long moment, clearly battling with internal feelings. However, moments later, she nodded just as firmly.

"Are you willing to serve me in the same way she does?"

She nodded a third time, just at the right moment when Dusk came in her throat.

If she was caught off-guard by the orgasm, she didn't show it. Instead, she showed control. She locked her mouth in place, guzzled down gallon after gallon, the sound of the leather in her outfit stretching from her gut expanding from swallowing so much cum. Soon she popped the head of his cock out of her mouth, allowing him to cum the rest of his load all over her muzzle, face, and mane.

"Excellent work, Luna..." Dusk panted, affectionately stroking her cheek and feeling her nuzzle back into his touch. "I'll be sure to call you in again soon so we can... properly start your service."

"Yes, My Lord," Luna nodded quietly. "Nothing would make me happier."
