Celestia's New Throne

Despite his doubts when the Princess shared her plan, Spike eventually relented. He knew Twilight Sparkle already had her suspicions, after all. But he almost hated to share the special little thing he had with Celestia. They were able to satisfy each other's needs, settling into a comfortable rhythm as they took charge in the bedroom. Even their dreams were a sea of bliss due to Luna's influence, ensuring that aside from his chores and her royal duties they were rarely ever apart.

It was a quiet evening when Twilight arrived. Silk curtains billowed around the balcony, the cool wind whistling in. “H-hi Twilight,” he croaked with a hard swallow. For a moment he felt so little again, fearful that she wouldn't improve.

“Hmm.” Clops sounded when Twilight approached, circling around him, her lips pursed. The moon's soft rays fell over them, the shadows crawling over the walls. “So...Celestia's told me all about what you two have been up to.”

“Yeah.” He rubbed the back of his neck. “I wanted to tell you, but-”

“I want to see it for myself.” Her cheeks colored. “For...scientific reasons, of course. Not much is known about pony and dragon mating habits. And you don't mind, do you, Celestia?” She looked over her shoulder.

“Of course not. That's why I called you here, after all.” She wrapped a wing around her former student and pressed her close. Her mouth pressed closer to her ear. “But wouldn't it be better to be an active participant?”

“What?! But I couldn't...with Spike...” She burned brighter.

“Why not? He's no longer your assistant. You're both adults. And I know you must have needs, no matter how much you'd like to believe yourself above them.” She traced a forehoof over her flanks, taking special care to massage her cutie marks.

Spike couldn't tear his eyes away, his loins stirring. Pretty soon Twilight whimpered under Tia's soothing touch, sitting on her haunches to try and hide the swell of her vulva lips, her inflamed canal forming a viscous pool of marecum below which matted her now sticky bottom. His dragonhoods crept out, the pair seeing each other as potential mates for the first time.

With a giggle Celestia whispered in a sultry tone, “Show her, Spike. You want to be bred, don't you, Twilight? You've been alone for so long, and it's not healthy to keep oneself so pent up all the time. I can tell you both want this.”

It was true. Twilight understood she was a sexual creature like any creature on an intellectual level, but she rationalized she was somehow above baser needs, that a quick masturbation session so she could get back to studying and work was all she required. But wasn't play a form of learning, too? And she gave herself so little time for recreation these days...

Still, she balked at the idea of mating with Spike. Certainly, he was handsome enough ever since he'd matured, but it was difficult not to picture her little sidekick when she looked at him. But she shook the image away. Until she accepted what he'd become, he'd never be able to truly grow. To her shame she realized she was still babying him, holding him back!

“I'll do it.” Twilight took deliberate trots towards him. “You can...can make me a mare, Spike!” She winced at her words, unable to hide her embarrassment when they slipped out, but knew they'd come from the heart. “But first...”

She indicated with a wave of her hoof that he should lay down. He nodded and settled onto his back. Turning, she leveled her shapely bottom towards him, and gradually lowered it down onto his snout. The sight of her wet slit, which dripped onto his face, and her puckered asshole filled his vision. Pretty soon her plush buttocks pancaked across his maw.

Gulping hard, she gazed transfixed at his pink twin dragonhoods. Naturally wetted and ridged with soft but firmly, flesh protrusions. Tentatively she poked his cocks, which wobbled a twinge. “I-I know what these are,” she wheezed. “They're too stimulate one's mate, which will open up their cervix entrance further, and...and allow more of his sperm to inseminate her.”

She burned to her ovaries. She'd released a few eggs, her body naturally wanting to be bred, to bear his Kirin. Her lower portions contracted, her womb dripping its goo, her tight slit which she'd only ever let toys touch winked. She reflexively whined to be mated and her face burned redder than ever. “Spikey, I-” She couldn't bring herself to beg for it, instead shaking her rump. Unable to deny somepony so close to her, he slid his tongue into her slit, starting to lazily explore her.

Tensing up, Twilight planted gentle pecks down his cocks, tracing her forehooves over their moist surfaces. She breathed in his masculine musk, unable to look away from his powerful entrances, both impatient and fearful to take them inside her.

Celestia raised a hoof to her mouth and chuckled. “Let it come naturally.”

The pair surrendered to their baser, always unspoken desires. He lapped at her sexholes, which squeezed around his tongue, able to explore her deeper than anything she'd ever dared try. At the same time she rubbed his girths upon her cheeks, and then moved towards the tips, thinking to take them both into her maw but realizing their was no way she could.

“Allow me.” Celestia marched up, and pressed her lips around one of the penis heads. Gently she laid a forehoof atop her former student's head, and pressed it down, helping her take in his salty length. Guiding her, they settled into a steady rhythm, Tia easily able to take him to the base, while Twi sputtered and struggled, desperate to keep pace and please him.

Of course it proved even more difficult when he started to grow once more, his lust-addled mind causing his bulk to swell with muscles, his meat distending their throats a tad. He grunted and wrapped his claws around their heads in a dominant fashion, eyes turning to slits, sliding into a more primitive state, seeing them as his prized mates to be taken as he wished.

Suckling on his dicks, slurping and tracing their tongues around his meatshafts, they inhaled his aroma. Thick wads of precum oozed onto their tongues and down their throats, almost enough to be a stallion's full emission, but was little more than the warm up that started to balloon their cheeks. They moaned and drank it down, addicted to the texture and flavor.

Grunts escaped Spike, who bared and clenched his razor teeth, eyes strained closed. His loins throbbed and his balls churned, his shafts blowing spurt-after-spurt into his newly formed herd, erupting down their gullets much faster than they could take. It burned up their nostrils, splashing out, smearing their gums and sticking between their teeth.

Eventually the pair were forced to withdraw, excess dripping down their mouths, a fresh layer showering their faces. They were absolutely drenched, loose hairs sticking to cum-soaked cheeks, tethering their stained eyelashes. The mares continually stroked him to the last drop, and he continued to throb and shudder with his latest volcanic release.

Barely giving them a moment's rest, he rose and flipped them over, stacking Twilight atop Celestia who were both on all fours. He swatted their flanks possessively, studied the way their buttocks wobbled and were marked red with his prints, and unceremoniously rammed himself into their marehoods which were thankfully rather wet by this time.

“Sp-Spike,” cooed Twilight, who nibbled upon Celestia's nape, their wings jutting out to full plume. Losing all sense of control, driven solely by lust at this point, Spike took his mares rather roughly, driving against their cervix entrances with repeated strikes. His ridges massaged their warm insides, kissed their g-spots, their final barriers further oozing and opening wide.

With another plunge he drove himself all the way into their slippery wombs. He bottomed out inside them, their stomachs warping, his claws kneading their asscheeks. Groans and moans mixed while he forcefully bred his equally lusty mates.

Their docks raised their tails, their puckered assholes clenching, their cunts milking him for all he was worth. His testicles slapped each time he humped them, mounting his prey, unable to think of anything else but putting Kirin inside them. It was their natural purpose; they were biologically made to be bred, and likewise, he needed to spread his seed and assure his line's survival. But like him, they were virtually immortal, and thus he could knock them up as many times as he wished!

Their bodies rocked under the savage blows. Twilight was the first to release, squirting atop Tia's wide buttocks, and she soon followed, the pair screaming and creaming. They shook and flopped, needily pressing their backsides into him.

Hollering, he hilted himself balls deep one more time. Both his rods popped in tandem, flooding their wombs directly with his splooge. Their stomachs flopped out loosely, swelled by his emissions, their eggs swimming in an endless sea of male milk.

Sanity returned to the predatory creature, and he lazed around his mates, still happily locked inside them. His wings and tail curled around his lovers, drawing them close to cuddle him, and they nuzzled his powerful musculature, drenched in sweat and a mixture of masculine and feminine excretions. “I love you two,” he whispering stroking their faces and manes.

“Thank you Spike,” murmured Twilight with tears in the corners of her eyes.

“You were wonderful,” mused Celestia. “Both of you.” She kissed Twi on the cheek.

“I'm the luckiest creature in Equestria,” said Spike, thankful that in his lust-induced state he hadn't harmed them. But these alicorns were tough. He was proud to call them his. Perhaps in time, they'd come out openly with their relationship, starting with their inner circle. But for now they were simply content to enjoy one-another's company.

Gradually the trio drifted into a peaceful slumber. And even then, Luna filled their dreams with more pleasant fantasies, so they never needed to be far apart from each other for long. He shared a smile with them, softly snoring well into the night.
