Bottom
Having successfully gotten past the castle’s guards, greeting them and brushing away their fanfare for her instrumental role in Princess Luna’s defeat, Twilight slipped down a side passage and deeper into the keep. To say she was elated would be an understatement of profound proportions. She’d successfully started a new life in Ponyville, reunited the Elements of Harmony, and vanquished Nightmare Moon, yet those accomplishments felt small in comparison to her greatest achievement - she had a marefriend.
It was hard for her to recall a time in her life when Celestia hadn’t been a motivational factor for her. The alicorn had taught her since she was a filly, being as much of a parent as either Night Light or Twilight Velvet, yet her view on the Princess had changed over the years. As she’d blossomed into adulthood, earning her former mentor’s respect, her true feelings for the Princess had done nothing but grow stronger. It was only after she’d reunited the sisters that she confessed how she felt about the alicorn who’d won her heart.
She’d expected things to go poorly, for Celestia to let her down softly and tell her that there was no way they could be an item, yet she’d been wrong - so terribly, wondrously wrong. The Princess had listened to her heartfelt admission, smiling softly all the while, until the most incredible thing happened. Instead of dejection, the alicorn had embraced her, given her a small kiss, and admitted that the feelings she’d secreted were mutual.
Glancing over her shoulder, ensuring she wasn’t being watched, she depressed a concealed panel within the wall and opened a trap door. The castle’s maze-work of hidden tunnels and escape routes had been designed in the event of an enemy attack, but they worked marvelously for all manner of clandestine purposes. Though she and Celestia had been an item for months on end, having shared several intimate experiences with one another while their bond grew, such affairs had to be handled delicately.
It was anypony’s guess as to how the public would react to the oldest, most influential Princess in the land taking her protege as a lover, so Celestia and herself had decided to keep things under wraps for the time being - sure it was inconvenient at times, but the taboo of their circumstances added an exotic spice to their time together. As she strolled down a spiral staircase, the gloom of the underkeep illuminated by her horn, her heart began to race.
While it wasn’t difficult for Celestia to disguise herself, the nature of this particular meeting demanded the utmost secrecy. There wasn’t much they hadn’t done with one another, both in or out of the bedroom, although there was something she’d always wanted to try. Though each bout of lovemaking with her mate was beyond reproach, always leaving her fully satisfied, they’d yet to try anything too kinky - that was until tonight.
She paused as she entered a hidden, subterranean chamber, channeled power into her horn, and ignited several crystals set in the walls. What had been an unused dungeon cell had been converted into something spectacularly depraved. The chains, implements, and furniture which were intended to deal with ne’er-do-wells would now be put to a far more erotic use.
Cocking her head, hearing the sound of footfalls approaching behind her, she smirked and reached for her top. Celestia was bigger and more powerful than her, so it only made sense that she take the lead for their first experimental bout of BDSM. Flitting to the center of the room, kicking her shoes to the side, she reached behind herself to unzip her dress.
“Is that you, Twilight?” a familiar voice called, sending an excited shiver up her spine.
“I…I’m down here, M…Mistress,” she sputtered, hastily unclasping her bra.
Neither she nor Celestia had any experience whatsoever with more exotic amorous practices, both being novices with all things carnal, yet that was far from a bad thing - in fact, it was a boon. Unsure of exactly what the Princess had planned for her, imagining all sorts of amorous torment, she stripped down and excited awaited the appearance of her lover.
As Celestia stepped into the chamber, her heart skipped a beat - that was until she noticed what the Princess was wearing. She’d fully expected attire that evoked feelings of arousal and dread, black leather and chains, yet her paramour was wearing anything but. Adorned in a pair of shorts and simple t-shirt, the towering alicorn looked over at her with a playful smile.
Looking around, seeing no garments save for her own, Twilight scrunched her snout. “I…I thought you’d…”
“Thought I’d what?” Celestia inquired, cocking her head while peering down at her crotch.
She hung her head and sighed. Though she loved Celestia with all her heart, it wasn’t that shocking to discover that her lover hadn’t come dressed for the occasion. Telling herself that the choice of clothing didn’t matter in the grand scheme of things, she lifted her head and peered over at the alicorn’s groin.
The fabric over Celestia’s crotch tented, speaking to the monster that lurked beneath the fabric. It was a well known fact that alicorns held traits of all pony races, yet she would never have fathomed how true that was. On the night she’d discovered her lover had the biggest, thickest stallionhood she’d ever seen, she was as surprised as she was thrilled.
“S…so…” she falteringly continued, tearing her eyes off the Princess’ bulge to glance over at the myriad of equipment around herself, “did you have anything particular in mind.”
Looking from one device to the next, Celestia thoughtfully rubbed her chin. “Honestly, I’m not sure. Do you have a preference?”
The question left Twilight gobsmacked and nearly caused her jaw to hit the floor. Her big-dicked she-stud being dressed for a casual date was one thing, but this was on an entirely different level of negligence. Celestia was supposed to be the one calling the shots, tying her up and mercilessly toying with her - not asking her what she’d like to do! Waving to a stockade beside her, she silently prayed that it would only take a little push to bring out her lover’s domineering side.
“Let’s start with this one,” she politely intoned, opening the contraption.
Leaning forward, she placed her neck and wrists in the device before using her magic to close its upper half. While she had perilously few nits to pick about Celestia, the biggest was that the Princess was startlingly submissive - something she had every intention of changing. With the sorcerous might to level cities, the physical strength to overpower dragons, and a stallionhood that would put any stud to shame, the alicorn should have been an absolute demon in the sack - unfortunately for her, it always took a bit of goading to provoke her mate into being even the slightest bit rough.
Celestia crossed the room and slipped out of her top, allowing her bounteous bosoms to spring free, before stopping just before her. “Is it not uncomfortable?”
“It’s…” Twilight stopped herself, moments from giving a very glib reply. “It’s fine. So what do you have in mind for me, Mistress? Are you going to lock me here and -”
“Goodness no!” Celestia gasped, wiggling her hips and drawing her shorts down. “Why would I want to lock you in that dreadful thing?”
Had it not been for the sight of the Princess titanic cock flopping free in front of her, Twilight would have expressed her discontent. Simply gazing upon her lover’s endowment was enough to dull her frustrations. Nearly as thick as her wrist and as long as her forearm, covered in velvety grey flesh, Celestia’s royal scepter bordered on the divine - even if it had taken a lot of time, patience, and sore mornings to get used to the size of it.
Celestia grinned as she strutted behind her. “I must admit, you’re quite provocative like this…”
“Y…yeah?” Twilight gulped, trying and failing to look back. “Why would you - Eeep!”
Silencing her with a soft spank to the rear, Celestia giggled. “Who’s my naughty little mare?”
Just like that, with those simple words, Twilight’s tail flagged. “I…I’m your n…naughty little mare!” she bleated.
Feeling herself starting to wink, she expectantly spread her legs. This was it, this was what she’d been waiting for, and she was dying to see what sort of punishments she was in store for. Unable to see what was going on, hearing the Princess shift, she sharply inhaled something warm and soft crept up her thigh. She braced herself, fully anticipating lilting words or possibly even another smack, yet she got neither.
“Allow me to warm you up,” Celestia cooed.
Before she could protest, the Princess dove in and began lapping at her nethers. As annoying as it was not to be harried, she couldn’t complain - literally couldn’t complain. Stifling a whimper, she rolled her hips back. If her lover wanted to start things off with a bit of edging, getting them both worked up, that was alright in her book; as long as things took a decidedly more intense turn at some point, everything would be just fine.
All things considered, she really didn’t have much to complain about. She couldn’t move her arms or head, the most glorious she-stud in existence was enthusiastically eating her out, and they had the entire night ahead of them. With a trail of nectar creeping down her leg from her slavering pussy, her eyelids fluttered.
On and on Celestia went, alternating from licking her clit to probing her depths. Her breaths grew heavy, her nipples rock-hard, and a drool beaded on her chin. It wasn’t until a singular warmth started to well in her abdomen, heralding her impending release, did she shake free from her impassioned stupor. If things didn’t come to a halt very, very quickly, the Princess was going to get a baptism of her orgasmic juices.
Forcing her treacherous body to comply, she squirmed and gently kicked back with one leg. “W…wait!”
Celestia paused and slowly, almost begrudgingly withdrew. “Is…is something wrong?”
“Yes something’s wrong!” Twilight harrumphed. “You’re supposed to be dominating me!”
Rising to her full height, the Princess stepped to the side and into view. “Are you not enjoying yourself?”
Peering up at her lover, seeing Celestia’s crestfallen expression, Twilight took a deep breath to soothe her tattered nerves. “Yes - yes, I’m enjoying myself, but that’s the problem ~ remember? We didn’t go to all the trouble of cleaning this place up just so we could get frisky in a dungeon.”
Celestia pinched the bridge of her snout and sighed. “To be fair, it’s not like I’ve ever done this sort of thing before.”
“Neither have I, but - wait…” Twilight muttered, squinting up at the Princess. “Did you even read those books I sent you?”
“I…” Celestia trailed off, averting her gaze while crossing her arms over her chest. “Of course I did.”
Less than convinced, Twilight quirked a brow. “Then what was chapter five about?”
The alicorn stiffened and shifted in place, her lips pursed, before her shoulders wilted. “I have no idea. I glanced over them, I really did, but I was simply too busy. Twilight, I’m so, so sorry…”
“It’s fine,” Twilight murmured.
She’d accounted for this moment, realizing that it was more than possible that her lover had become preoccupied with her official duties. Clearing her throat, she gave herself a moment to calm down. With a pinch of luck and a bit of finessing, the evening would still be salvageable - she hoped…
“So as a dom, you’re supposed to abuse me a bit,” she explained, drawing a shocked gasp from the Princess. “I’m your sub, so you should use me like a toy - teasing me, fucking my brains out, spanking me, there isn’t much that’s off the table.”
“I’d h…hate to do anything too extreme,” Celestia lamented, her kind words standing in stark contrast to her colossal endowment. “If you were in my shoes, what would you sugg-”
“Fuck my face,” Twilight interrupted, staring longingly at the log of flesh swinging between the alicorn’s legs.
Though Celestia stayed silent, peering down at it, it was what wasn’t said that spoke to her success. The Princess’ cock jerked upward, swelling to nearly its full, incredible size. To hammer the point home, more than ready to get things started, she opened her jaw and invitingly extended her tongue. If the sight of a mare asking to get her throat swabbed wasn’t enough to get somepony going, nothing would be.
“W…well, I suppose I could…” Celestia breathed, repositioning herself and bringing her colossal dick to bear. “Just tell me if I’m being too harsh.”
“Uh-huh - yeah, sure,” Twilight hastily replied, swiftly opening her maw for the Princess’ approaching length.
Staring down the imposing length, she shuddered when the broad, fat tip graced her tongue. Stars above - regardless of how her plans had fallen off the rails, it would have been impossible for her to be upset while sucking Celestia off. Inch after girthy inch of shaft crept into her muzzle, coating her palate with the earthy flavor of unwashed flesh and filling her sinuses with the ambrosial scent of musk.
As her lips tenderly closed around her lover’s stallionhood, she closed her eyes. She would never have guessed that Celestia had such a perfectly intimidating appendage, especially since she’d grown up around her, but that was hardly a complaint. Slowly bobbing her head, she put her tongue to work.
“Mmmmm,” Celestia approvingly hummed overhead. “That’s nice.”
The statement should have comforted her, warming both her heart and loins, yet it gave her a moment for pause. Twisting her head to the side, she glowered up with one eye at her mate. She’d said she wanted something more than tender treatment, and she’d meant it. With the utmost hesitation, apparently realizing she’d erred once again, Celestia reached down and clutched the base of her skull.
She took a deep breath in preparation, filling her lungs for what was to come. The Princess stepped closer and drove her hips forward, driving the gargantuan length into her gullet. With a stifled gag, doing everything she could to relax her throat, she felt her neck bulge outward from the immense intrusion. Her eyes wandered forward and gazed down the shaft before her, filling her with glee.
Despite her telling Celestia dozens upon dozens of times, she loved being pushed to her limits. Her jaw was forced open, her tongue driven down, and her airway totally blocked by the thick cock sliding into her. The intensity of it, the trace of discomfort mingling with the physical and psychological delight of servicing someone so magnificent, was almost enough to make her cum on the spot - almost.
As her lips touched her lover’s medial ring, Celestia rolled her hips back and began bucking in earnest. The long, steady plunges were just enough to let her get the periodic sip of air, flooding her nostrils with the alicorn’s bouquet, while her marehood needily clenched upon itself. She instinctively moved an arm, attempting to tweak her nipples, but was reminded of her position. For future attempts, she’d be sure to lock the stockade and have a negation ring handy - that said, she was happy that things were finally moving in the right direction.
The Princess’ thrusts gradually grew harder and faster, though not nearly as harsh as they could have been, as her passion soared. There’d been plenty of times when she’d been turned on by her lover, but this time was different - this time she couldn’t do anything to relieve the ache in her loins. Seconds stretched into a minute and longer still, her marehood leaking to the floor between her feet, until Celestia finally slowed.
“Had enough?” the alicorn mused, peaking a brow.
Relishing the sensation of the shaft fleeing her throat, Twilight mopped the length free of saliva and pre-cum until the bloated tip popped from her snout. “Yes - buck yes.”
“Good,” Celestia purred, “because now I’m going to give you what you deserve.”
“Wait - seriously?” Twilight squawked. “You’re going to rut me already?”
Stepping down her side, Celestia rested a hand on her tush. “We’re both clearly turned on, so I can’t see why you wouldn’t want us both to have a bit of fun.”
“At…at least spank me some more,” Twilight stammered, her raging libido waging war against her expectations of being properly dominated.
The princess came to a halt behind her, looking no less conflicted than she had been earlier, and tentatively raised a hand. “Well I s…suppose I could…”
Smack
The slap on the rear was followed by a second, then a third and a fourth, until Twilight unleashed a shuddering sigh. She hadn’t been more turned on in - well, she couldn’t recall ever being so turned on before. The spanking really wasn’t all that harsh, yet the bit of pain elevated her arousal beyond measure. Glancing to the side, spotting a paddle hanging from the wall, she broke the promise she’d made to herself not to use her magic and levitated the item over.
“Use this,” she breathed, arching her back and presenting her ass.
Celestia reluctantly took the item from her sorcerous grasp. “Are you sure? It looks like it will hurt…”
Screwing her eyes shut, Twilight shook her head. “That’s the point. Spank me with it while you plow my brains out.”
The irony of the situation wasn’t lost on her. Despite supposedly being at Celestia’s mercy, she was the one giving the orders - still, she was losing her patience. If she’d spent a bit more time and thought into the endeavor, she would have put herself in charge to show the Princess how things were really done, but that could wait for a later time. As she stood on her tiptoes with her tail flung to the side, holding her breath and waiting expectantly all the while, she was rewarded with a strike to her rear.
“Mmmmmph,” she groaned, gnawing her bottom lip.
Withdrawing the paddle, Celestia ran the leather over her flank. “Another?”
“Yes, darn it,” she pleaded.
She was growing desperate, yet in a poetic, unexpected way. The next blow came after only a second of hesitation, setting her nerves alight and causing her eyes to roll back slightly. Yes - buck yes, this was the way it was supposed to be. Locked up and amorously abused by her demigod she-stud, she whimpered in unfettered glee.
Maybe it was because she’d always respected Celestia, having always done her best to please her former mentor, but the thought of being used in such a salacious fashion never failed to moisten her panties. She threw her head back and brayed, her knees buckling and thighs quaking all the while. If she hadn’t been placed on a hair trigger before the kinky treatment, she sure as Tartarus was now.
It wasn’t quite as merciless as she would have liked, but her rear was tender and undoubtedly reddened by the time Celestia drew to a halt. Fighting to catch her breath, with sweat beading on her brow, she started when something warm and fat kissed her lower lips. Feeling a hand glide up her flank and to her waist, she knew that the time had finally come.
“Do it,” she mewled, attempting to roll her hips back, “rut me like I’m your slutty little mare.”
“That’s because you are my slutty little mare,” Celestia tittered, sounding a bit more sure of herself.
No sooner had the words passed the Princess’ lips than she was spread open. The breath hitched in her throat, her heart skipped a beat, and she almost came on the spot as she was impaled. By all the stars in the sky, nothing - nothing could compare to the feeling of being stretched open by the alicorn’s heavenly endowment. Inch after wondrous inch was driven into her, until her lover’s medial ring bumped against her entrance.
She hadn’t foreseen Celestia continuing to use the paddle, having nearly given up hope, so the blow to her rear as the Princess withdrew sent her sailing over the edge. Her rapturous wail reverberated off the stone walls, echoing in her ears, while climactic nectar gushed from her spasming depths. Waves of blinding pleasure crashed over her, eclipsing her annoyance in the blink of an eye.
“That must be a new record,” Celestia moaned, freeing a portion of her length. “Maybe there’s something to this kinky stuff.”
“Uh…uh-huh…” Twilight thoughtlessly replied.
Even if she’d been free to take a more active role, she wasn’t sure how much she would have been able to do. More often than not, she was the one who took the lead in the bedroom, worshiping Celestia like the goddess she was, but this time was different. Robbed of her freedom and overwhelmed with ecstasy, it was all she could do to remain standing and endure the carnal onslaught of her mate.
Grunting with each of the Princess’ thrusts, Twilight glanced to her left. While being blindfolded would have been nice, having heard that robbing one sense heightened the others, a part of her was glad that she could still see. Spotting herself in a mirror against the wall, she was given the opportunity to watch herself getting railed.
The muscles in Celestia’s legs and arms rhythmically flexed as she drove her hips forwards and back. Being significantly taller than average, and with strength to match her size, the alicorn was like an amazonian deity. She shifted her gaze, seeing the paddle lifted in her lover’s free hand, but there was nothing she could do to stop her mate.
As the leather impacted against her flank, she hissed and involuntarily clenched around the pistoning length stretching her insides. Compelled, her marish instincts seized hold. Constricting and relaxing her depths in tune with the Princess’ plunges, her marehood milked Celestia’s cock for all its worth. Reduced to little more than a lustful beast, she panted and whorishly moaned.
Celestia gave no quarter, succumbing to her she-stud urges, and eventually dropped the paddle to grip Twilight’s hips with both hands. The aroma of sex filled the air, their colliding bodies crafted a drumbeat, and the floor grew slick with a cocktail of marish juices and pre-cum. The Princess may have been loving and gentle to a fault, yet the combination of novel kinks and their surroundings took a toll on her inhibitions.
Twilight cried out yet again, wracked with another climax, while sparks sailed from her horn. She had to admit, even with her faults, Celestia was a peerless lover. The battering-ram like stallionhood within her battered her womb, the thick medial ring ground against her g-spot, and the Princess’ fat, cum-laiden balls slapped against her clit, erasing what little refractory period she had and sending her skyrocketing towards another orgasm.
Time gradually lost meaning as she was hit with wave after rapturous wave of ecstasy. She couldn’t say how long she stood there, locked in the stockade and unable to move, but she snapped back to her senses when she felt her lover start to flare. Summoning a strength she didn’t know she had, she bore down and squeezed Celestia’s cock.
“I…inshide,” she slurred.
“I…I’m gonna,” Celestia croaked, frantically pounding into her.
The Princess gave one final, unstoppable plunge, sheathing every inch of her incredible shaft, and draped herself over Twilight’s back. As warmth blossomed deep in her abdomen, her interior coated with thick, virile seed, she came alongside her lover. Nothing in the world quite compared to being claimed, taken and bred by her mate, and it was the perfect way to finish what was an imperfect evening.
Celestia shudderingly lifted her muzzle and brought it to Twilight’s ear as she reached around to lovingly squeeze the mare’s breasts. “Was it as good as you hoped?”
“M…m…” Twilight began, finding it almost impossible to speak. “Mostly…”
“Mostly?” the Princess parroted, shifting to look her in the eye. “How mostly.”
“Should have used those,” she breathlessly replied, weakly nodding over to a rack of toys, tools, and various pieces of bondage equipment. “D…don’t worry, I’ll show you h…how it’s done next time.”
Exhausted and satisfied though she was, she’d meant what she said. The christening of their little playroom was a trial run, so she should have known things wouldn’t go exactly as she’d planned. She twisted her head and gave Celestia a peck on the nose, relishing the stunned look in her mate’s eyes. The Princess may not have realized it, but she was already formulating a contingency for their next little foray into BDSM…
Slapping the crop to her hand, Twilight smirked. “Somepony’s bad little Princess,” she cooed, reaching out and caressing the crop’s tip to her nipple.
