Take a Load Off

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."
