To desire and be desired.
In Canterlot it was a beautiful day! The birds were shining, the sun was singing-
No, that wasn't right. Thorax shook his head, attempting to clear the cobwebs and dismiss all the errant stress clinging to dark corners. He knew the experience was supposed to be good for him and his changelings, but sitting in on Luna's mediations between the gryphons and the yaks just left his head spinning, brain hurting, and attention scattered. How could there possibly be worse international relationships than those left to him by Chrysalis? That wasn't quite right either. It was probably just the frustration talking.
Even so, he checked over his withers before again glancing out from the elevated arcade while he walked. Same birds, same sun, and no Discord, so it must just be his own addled brain mixing signals.
Thankfully Luna had called for a recess after yesterday's arguments between ambassadors Garoda and Hayes became the order of today, then devolved into an escalating circular yelling match about talons versus horns. Clearly pincers, but that was neither here nor there. The break was very much a welcome one because it was the perfect excuse to retreat to somewhere he would much rather be. A left turn at the end of the arcade brought him to an elaborate hall with paired spiral staircases on the outside wall. Upstairs was a mirrored hall - both in size and opulence that he still wasn't used to - but more important was the wing around the far corner from there. He had to force his elytra to rest and hooves to slow so he wouldn't abandon his shorter-legged escorts, flashing a sheepish grin as they caught back up.
Another turn took him through a ridiculously-sized passage, all the windows of its clerestory open to let the fresh afternoon air caress his fuzzy antennae. A couple of pegasus guards were up there lounging, though armored and clearly ready. The subsequent receiving area was large enough that the dozen assorted guards and hoofful of other staff casually waiting and chatting seemed completely inadequate. He went right up to the senior of the three changelings already present, nodding his three off to join them.
He lowered his head to their level. "Luna called a recess, so I've got some time to myself. I don't think there will be much to do for a bit, so, um, I guess if you all want to relax, then feel free to."
The saluting still felt completely unnecessary, but they still followed his intent, grouping up several lounging pillows and forming a colorfully chitinous circle. Turning, he passed the rigid pony guards, both white and deep gray, eking out an awkward grin for them as he did. Two massive doors stood opposite the room's entrance. One was Luna's, the other he gently slipped through. Beyond, in a shaded sitting area, two nurses looked up at him.
"Is she well?"
The pale teal unicorn on the right nodded. "Yes, sir. Just as when you left."
That brought a true smile. "Thanks. Um-" he fidgeted. "Would you mind waiting outside now?"
"Of course." The unicorn bobbed once as the two headed around him. "Again, you needn't worry about asking for privacy, sir."
"Of- of course."
Then they were gone. Being a king - especially among ponies - was certainly a strange experience. Shaking his head, Thorax moved deeper, entering a proper living room decorated in a striking combination of purples and night blues, all accented with rich oranges and reds. Personal knicknacks were everywhere but despite some pieces of conventional furniture around the periphery, the most prominent feature was the world's most comfortable floor poof in front of a large, currently-empty fireplace. There was a small scattering of writing supplies near it, but missing was the world's most likely occupant-
"This sucks!" The sharp sound struck hard, entirely at odds with the dulcet voice.
He suffered a flutter of unease, his ears snapping against his head. "That's not very princessly."
Princess Celestia's head popped around an embedded pillar at the edge of one ornate partition wall. "Oh! You're back!" She grinned, ambling into the room. "In the comfort of my own apartments I'll be exactly as unprincessly as I like. This does suck! I've had to pee three times since lunch!"
"Oh." He still wasn't sure how best to respond to that. "Sorry?"
Her coat shined, magenta eyes practically sparkled, and mane and tail gently rolled her brilliant colors, but all that was expected. These days the most eye-catching thing about his beautiful princess was something else; something entirely new for the both of them. Between her fore- and hindlegs her belly had swelled into an impressive mass that swayed ponderously, giving her every step a very slight, almost drunken wobble. It was absolutely adorable, not that he would ever admit that to her. He wasn't sure what might come of it if he did, but it just felt safer as a secret.
"Sorry? Pfft! Don't be."
He marveled as she approached, taking in everything about her perfect, generously round form. At least until she got within range to present her tilted head to him. He could bear to take his eyes off her if it meant a long, cheek-to-cheek rub.
"You didn't do this to me," she insisted next to his ear.
"But I di-!"
"Shhhh!" Pulling back, she dodged the tip of his carapace, pecking warm lips against his own. "You didn't. They did." Looking him right in the eyes, she patted her wings against her flanks.
"You're blaming our-?" Her sharp look silenced him.
She smiled again a scant moment later. "No. You can be so silly sometimes."
"Then…?" He sighed; it was a conversation that always left him confused. He still hadn't figured out what she meant by any of it, which she coyly seemed to relish. "I just worry."
"I know. You're always so considerate, but I promise this isn't something you need to worry about. I know you will anyway, but just please remember that."
This time he delivered their kiss. "I try."
"I know you do. Here."
She wobbled by him, running a wing down his back as she made for the great poof and the comfortable divot she'd installed in it. Getting onto it was an exercise in practiced grace; flopping onto her side very much wasn't. He trailed after, uncertainty spiking as she kicked once in surprise before using her wings to right herself. Even then her gravid form no longer allowed for resting upright, and her jutting flank meant she had to do her lounging in a bit of a twist. Thorax couldn't imagine how her contortions weren't horribly uncomfortable, but since she kept adopting the pose, he must clearly misunderstand pony anatomy.
Following her, he kneeled onto the poof, pushing himself across it to meet her. Their muzzles met just long enough to lead into a loving cheek rub.
"So, tell me how it went."
"Well…" He pulled back so he wasn't just talking into her neck. "After yesterday's fighting-" he flinched, "-Ambassador Garoda rescinded his offer of assistance for Peakholme-"
"Even Hayes should have known better-"
He nodded, closing his eyes a moment. "But he's a yak, and Grampa Guff is Grampa Guff."
"I think that's why Prince Rutherford likes him; he's like an avalanche." She giggled, a happy sound that always made Thorax smile. "Set him off and you better get out of his way." The next was more somber. "But it's not easy to clean up after."
He hummed an agreement, eyes drifting to where they were always wont to go: her swollen belly.
"And what was Luna doing today?" She shifted her wing away.
He traced the long, now-revealed curve of her flank with his eyes, his heart fluttering. Bringing up a hoof, he began massaging gentle circles into her coat, following it over and around, feeling the rise and fall of her breathing.
"Um. Standing in the way of the avalanche."
Celestia's laugh jiggled his hoof. "And?"
"She was…" He paused, searching for a suitable level of diplomacy. "Fine. The conference table had to be replaced again."
His princess' giggles kept founding new colonies.
"I think she meant to wear him out before letting Garoda say another word-"
"She hasn't!"
He just couldn't help himself. The expansive, satiny-soft coat called to him and so he shifted sideways, pressing his snoot into her flank. "She tried," he murmured directly into his love. Somewhere right beneath him were his two foals, and he couldn't help but want to be as close as he could make himself. That doing so also brought him closer to her was so much the better.
It also meant that everything else waned in importance. Here was his princess, and here would he also be. "How are they today?" He stretched a leg across her, trying and failing to hug around her middle as he brought his cheek to bear. Rubbing against her, his antennae drifted across withers and one wing, letting him know she was fresh, vibrant, and clean. It also made her wiggle.
"A little squirmy. I think they're plotting something."
"Hmmmm…" He lazily opened an eye, examining how her rotund form took up the whole of his vision. Bringing his other foreleg around, he draped himself over her, luxuriating in the warmth and slight give that became unyielding, letting her breathing lift and lower him. Why this should make him so happy he didn't understand, but he'd long ago decided against questioning it. With both hooves he began working opposing circles into nearly opposite sides of her.
She sighed gustily, and a hoof began tracing the outer edge of one of his elytra. "Why are you so enamored with fat princesses?"
His ears pulled back, heat rising up his carapace, and he fired back the only way he could think of: changing subjects. "We're sure there's only two of them?"
She softly snorted. "Yes."
"Truly, absolut-?"
"You've been there for every visit with the doctors. Only two… Most ponies only have one."
"Feels like three hundred in you." What he could feel was definitely at odds with what his ear against her detected. There was and had long been a small chorus of heartbeats, though well short of the cacophony there could have been had a changeling been this pregnant. Not that any ever were; Celestia's state was far and away greater than any nymph could safely reach. It was his main source of worry even if she only ever seemed better and better for the experience.
He stretched further, trying to encompass the whole of her, and brought his whole body into the massage.
Her hoof trailed rearward across him, marking gentle designs into the top of his haunch. "Mmmm… Careful. This princess is sensitive."
"Do you want me to stop?"
Warm lips pecked the point of his stifle, right on the border between intimate and adventurous. "I didn't say that."
It took a very short moment to sort his options. Without leaving her, he turned his head, looking down the crest of her flank to where her hind legs made room for a whole different kind of swell. Her teats were prominent, full, and rounded. It was a very different kind of unusual for him because changelings had nothing of the sort. Confusingly, considering how he somehow couldn't get enough of her growing belly, her teats did nothing for him. Neither good, nor bad.
But they did much for her, and that was what mattered most. His left hoof migrated again, just barely skimming the nearly taut flesh. Her resulting intake of breath was a beacon. Carefully catching one nipple between the wall and frog of his hoof, he moved it in small, slow circles. The other one visibly straightened. He let the first go, slipping his hoof into the crease between and then to her other teat, gifting the second nipple with similar stimulation. The first firmed up further.
At the same time, light impressions of teeth at the point of his stifle cast excited tingles all across his hindquarters. His princess knew him well, and when his hinds shifted, her smooth hoof deftly slipped in to tease one of his truly vulnerable areas.
Much like his indifference with teats, she had no great love for his aedeagus. In that, he felt very fortunate to be a changeling, or intimacy would have regularly been prohibitively awkward. With a hum, he focused, pushing at himself. A sharp sensation formed between his legs, growing from a simple point to spread inward while simultaneously extending forward under Celestia's gentle ministrations. The form was easy enough, but shifting from complex, hardened structure to comparatively simple, supple skin and flesh brought a hike in sensitivity that always locked him up for a bit. Unfortunately, Celestia's heated breath gave him no time to again ponder how accurately he recreated sensation; warm lips put a lingering suckle against the side of his new cock.
"Mmmmm. Thank you." She was always so considerate about it too. In the background he heard papers sliding across the carpet and away. Clearly she was serious.
Then her lips led her tongue up his length, sharply drawing from the breath out of him. His elytra involuntarily clicked; this was so much better than playing fifth hoof in some angry diplomatic meeting. Hugging her belly more tightly, he showed his appreciation the only way he could think of: he applied a fraction more pressure, moving first one teat then the other in increasingly complex small circular patterns. While she elicited a growing stream of twitches and flexes from his stallionhood, he teased her to greater and greater gasps through her now most sensitive area. Already the room was awash in love and affection, and it was only getting denser against hos senses.
As though there was some agreed upon trigger, Celestia spread her hinds, fully bearing herself to the world. He left his position rubbing cheek lines across her flank and haunch, craning down and between her legs, twisting so he could lip at the tip of her mound. The best of her was barely out of reach, but his long tongue was more than nimble enough to bridge the distance. As he curled it around to taste her, the end of his cock was captured. Hard texture on one side of him contrasted deliciously with the very mobile softness on the other, and it became so much more when her pressing warmth pulled heavily at his tip. They squirmed as one, she letting up and sucking again in sequence as he drew his tongue against and across the tense skin just outside her core. Only a moment later a small portion of her shifted sharply against his questing, accompanied by a short wash of lightly flavored moisture. The huff she made on his length was music to his ears.
He almost had her.
His flexible appendage found the boundary line that hid her from him, teasingly tracing up and back as though he couldn't truly figure out where to find what he sought. He slathered over and around, awaiting a key shudder in the legs to either side. When it came and her nub again flashed its unmet desire, he pursued it back, playing against the deeper muscles that tried to grab and hold him. The faint, sweet tang of her bathed his tongue, sending a ripple of heightened sensation through him that nearly pulled him free of her mouth.
She murmured amused denial right into him, clasping him with both hooves before pressing further, a whole new heated texture surrounding the tip of him.
His groan blew heated air across her nethers. With determination he redoubled his efforts, relishing in the rising wealth of emotion suffusing the room. If he could lift her arousal high enough, it would become an ambience he could practically swim in. The middle of his extended tongue took up the task, pressing against the haven where her button hid. There was no escaping the little wriggles he stroked over and around it, nor the way that also tickled her deeper reaches, his thin tongue just strong enough to titillate without overwhelming. When his target finally leapt for the cool freedom of open air he curled his tongue around it, drawing the whole length across her clit at its moment of greatest vulnerability.
Her belly heaved beneath him, a high pitched moan on his cock matched by another rush of liquid spilling over his taste buds. With a sharp inhale she slurped off of him.
"Okay, okay!" She pushed lightly at the insides of his hinds.
He flinched, shimmying back a bit and lifting his head free. He still couldn't bring himself to undrape from atop her belly though. With a slightly sheepish grin he retracted his tongue. "Too much?" His hoof paused its gentle motions against her teats.
She blinked, then rolled her wonderful eyes, using a hoof to make a circular motion toward her rear. "Just turn around there, you silly bug. I didn't agree to this break just to be teased." One perfect white hoof trailed up his deep purple stallionhood, circling the broad end once.
With a little jitter he grinned. "O-okay." Now that they were at this moment, he didn't want anything less. He scooted further, turning and sitting up on his haunches, his slicked pride rising at attention before him.
She watched coyly, her eyes flicked down once, broadcasting obvious mirth. "Was this why you fled my sister so quickly?"
Sudden, unasked questions raised only unfortunate answers about his flight from the conference hall, bringing a different, very uncomfortable kind of warmth to his cheeks. There was a very specific insinuation there that he wasn't sure whether to confirm or deny. One was honest, but the other was a more fun untruth. Given who she was and that he was thoroughly, happily hers, he could only ever choose one option. He shook his head.
"I would rather be here with you than listening to some- some… angry beings being-" it was hard to find the right way to vent, "-so unfriendly."
The apartments again rang with her laughter. "You know you don't have to hold back your true feelings around me. Not here, where I'm often very unprincessly." Her lips pursed. "And speaking of… What will you do next?" She dipped her muzzle then, playfully wide eyes gazing up at him through her eyelashes.
Sitting there and looking down with her on her side, her legs curled cutely, wings half extended across the poof, and undulating tail nearly covering her nethers again, she was a striking sight. He was drawn to her great belly, wanting nothing more than to snuggle to it with as much of himself as he could manage. Its sheer size was the issue; many ways they had previously been intimate were just no longer feasible.
"How does my princess want it?" He placed his forehooves right behind her rump, looming over her and flashing an easy grin.
"Mmm-mmm," she denied, shaking her head. "You're the great changeling negotiator, facing down irate gryphons and bull-headed yaks. What's your offer?"
"O-oh." The ball was fully in his court then. He blinked, letting his eyes roam over her, trying to pair his desire with something that she would enjoy just as much. The struggle wasn't worth it when simple yet effective was right beneath his muzzle.
"How about you roll?" He motioned bottom to top across her flank.
She braced, slipping a wing beneath herself, then settled back with her undercarriage facing straight up, careful with her hinds as they came up on either side of him. All of her hooves remained submissively curled and she stilled, clearly awaiting his next move.
Involuntarily, his cock flexed, smacking his belly plates.
But he needed and desired no words when her fullness was so prominently displayed right beneath him. Withdrawing, he trailed both forehooves across her great rounded expanse of white, and for just a moment he admired the smorgasbord of temptations she presented. His goal was specific though, and distraction wouldn't do when she clearly wanted - needed - him. His elytra clicking once with excitement, he lowered his head, closing with her now-bared damp nethers. He lavished her once, long and slow, bringing up a heavy dollop of lubricant - the component that made changeling resin initially so gooey - pressing deeply into her resistant quivers and corkscrewing his tongue to reach everywhere. Now her pussy positively glistened in the afternoon light.
A greater allure pulled him forward though. His chin led the way, meeting the generous arc of her belly above her teats, followed by his neck, then chest, forelegs, and undercarriage. He practically slithered up and over, lost in the joy of this part of her pressing into nearly the whole of him. As he crested, finding her amused smirk and happy eyes, she raised a hoof to be tickled by one fuzzy antenna. Again, vigor and cleanliness shone clearly to his senses.
He stretched and she reached, his lips finding hers, holding together hotly while the head of his stallionhood quested. Its first find was warm but dry, creased between hard tail and resistant tailhole, but direction had been given. A slight shift brought him up- The very tip of him slotted ever so slightly into slick raw heat, triggering a quiver and small movement against him. She breathed huskily and he grinned.
Had there been a whole different motion beneath him? It was quite possible, given her advanced pregnancy. That would be badly awkward. He planted one forehoof beside her, braced, and bent nearly double to bring his snout against her forward curve. "Don't you pay any attention to what mom and dad are doing. None. Okay?"
She was laughing before he even finished, shaking the whole of him. "They'll be fine." Her hoof found its way under his chin, guiding him back to her by touch alone. "Just be gentle," she breathed into him.
He nodded, grinning a bit goofily. Though it seemed their positions wouldn't be gentle in return. If they had been on the bed in the back, she would have been elevated in a way that let him get close comfortably, but here on the poof he had to contort himself to reach her. His rudder wing was bent badly backward and his hind legs were compressed into themselves, all just to accommodate his hips being so near hers. It was a problem that he needed to solve for both of their enjoyment. After all, she was waiting on him.
Then again, she'd shown flexibility despite her heavy state. He groaned, pushing up and forward on a whim of growing confidence. Her hips lifted, bringing her belly along as though she were being rolled into it, her wings snapping out to balance the shift toward her withers. As they rose together, the pressure against the head of his cock peaked, her nethers finally giving way, slipping around and engulfing the first of him. Surprise kept him going for a second and another couple inches slid easily in, her clutching heat throwing up a surge of pleasure that held him helpless for a moment. She just smirked.
"G-good?"
"Perfect."
Her breathy reassurance cemented his confidence, especially since the new angle was a blessing in itself. His legs welcomed the comparative freedom, letting him know just how much his leverage was increased. This was exactly what they both needed. He pressed further, burying a bit more of himself while stretching his neck down for another kiss.
She bypassed him though, rubbing cheek against cheek, exhaling long and heated beside his ear as he pulled back very nearly to the limits of her vulva. Her grip on his cock tightened then, begging him to not vacate her. He would never. Returning, he pushed through the pleasure to delve even further, turning the motion into a rhythm: every slow withdrawal tugged at her outer reaches, every questing thrust slid just a little deeper. Slick warmth quickly smeared its way up his shaft, spread along by her grasping, quivering sex.
As one of her hooves found its way to the front of his chest and the gemules there, putting her love in direct, near-overwhelming contact with his emotion senses, she relented to be kissed again. Her lips came at him fiercely, initially surprising and forcing him a few inches backward across her belly. That wouldn't do! Atop her was exactly where he most wanted to be! His next surge repaid her in kind, bouncing her whole body against him, an instant of resistance across the body of his stallionhood firing a spark of ecstasy through him. She clearly noticed too, her moan and fresh wetness surging over his upper shaft told him just what she thought of his medial ring.
Being so deep within his princess also let him be so much closer to her everywhere else. Her curvaceous form held him up, deliciously conforming him to its bounds, moving in time with his every action. That he could experience the whole of her so completely only heightened every baser sense rising from between his legs. As with so many of their previous dalliances, he couldn't help but spare an iota of himself to wonder whether he'd erred. In the moment, and in danger of succumbing to the rising tide of love-laced pleasure, it didn't seem possible that any stallion wouldn't be overwhelmed, forced to bear this level of sensation day in and day out.
His rhythm grew a bit off-kilter as he threw aside his distracting thoughts and instead lent himself fully to the pursuit of rising passion. For every measured withdrawal that allowed a fresh angle on Celestia's pleasures, uneven hooffuls of sharper thrusts bounced her teats against his belly, resulting in minor shocks that jostled him in return. Every motion - every buck - was accompanied by the faint wet pop of his medial ring slipping into and out of her. As a whole, it was a self-expanding feedback loop, and it was working. She was losing herself just as he was, her muzzle scrunching. He could no longer manage a proper kiss, the spark fizzing at the tip of his cock being stoked into full flame by her clutching silken confines. A simple boop was all he could manage.
Gasping, Celestia's forehooves shot forward to hook behind his elbows and she curled further, hanging onto him as though she herself depended on it. Perhaps she did. Her quivers and twitches were clearly reaching an apex, his constant attention to teats, nub, and deeper reaches driving her on just as fast as her unrelenting grip was doing to him. The final cue was when she latched teeth onto the tip of his chin carapace, hissing and pulling him insistently forward. Her pussy's regular grasps at his shaft went erratic, fluttering across him in unmeasured bursts, flecking first his sheath, then his whole groin with volleys of liquid desire.
Only a couple thrusts into this, and practically drowning in ambient passion, the flame growing within his cock roared out of control. Hugging to and pawing at her swollen middle, his every sense dimmed, one by one focusing on and being subsumed into the rush spreading up his shaft. He was already flying past any possible stopping point, but the sudden increase in resistance from his flaring head finished him off.
He'd once heard that stallions came in spurts, rapid and short, firing shot after shot into their lovers. It was something he had to take on faith, because though he wore a pony's equipment, deep within he was still a changeling. His gut, groin, and shaft clenched in sequence, emptying a long, hot stream deep into his perfect princess' core. He only managed a couple more thrusts before strength completely left his shaking hinds, collapsing him against her, his muscles relaxing in reverse only to clench and recreate the previous dousing. Twice, thrice, four times he seized up, flooding her again and again with seconds-long bursts until she squelched with every little shift and shudder of her own climax.
As ever, it was almost too much to handle, and it was all he could do to suck in labored breaths until the burning ecstasy ebbed enough to feel again. First was Celestia surrounding his stallionhood, smoothed by the thick slickness he'd filled her with. One last weak heave tried to revitalize him into cumming. The next thing to return was the warmth she shared, radiating directly into him. Then was his position, limply sprawled over her swollen middle with his muzzle nestled into the base of her neck, his wings splayed and focusing the light into scintillating points that danced across them both. Last was that the room - the world - around them continued to exist.
Planting one trembling hoof, he levered himself up a little, relieving her of himself. His princess was radiant, smiling up at him, a faint tiredness gracing her features. He grinned happily back, eyes locked on hers as her mane gradually resumed a calmer, more regular flow.
"Good?"
She just sighed, breathy and satisfied, her hoof coming up to stroke his cheek.
He chuckled, a thrill rushing along his carapace. Shifting, he slid his softening length free, revealing the splattered mess they'd both become. Even so, only the barest outwelling from her lower lips hinted at how much remained nestled securely within.
A bit of shuffling brought him around and she rolled to face him. Their rearrangement was almost prearranged, with him settling against her, again laying head and forehoof across her great flank. He'd naturally returned to their original embrace which placed his haunches forward, forming a perfect bed on which she could rest her head and neck. Their snuggle was completed when she laid her wing over him. It was a bit warm for him after all the exertion, but he was too comfortable to be bothered. Everything he needed was here and now, so he began rubbing his cheek into her coat again.
Something small moved within her. His ears folded. "I think we disturbed them."
"I'm sure they're fine," she asserted. "This was wonderful."
That brought perk back to his ears and antennae. "More fun than what you were doing, I hope."
"Oh yes," she purred into his carapace. "So much better than trying to diplomatically explain to Queen Novo why we can't fill one of the diplomatic suites with salt water."
His snort became full-on laughter. "Because it's a bad idea?"
"Especially because it's a bad idea."
Together they lapsed into comfortable silence, something which Thorax was content to nurture despite how sticky they were becoming. The sun was shining, he was disheveled, his princess was sated, and love and affection were literally in the air. If he had any choice in the matter, especially after all their activity, the rest of the day could simply pass them by. It would mean more time with Celestia and more time with his foals. More importantly - his free hoof began stroking the curve of her - it also meant more time-
"Horseapples!" Celestia jolted out from under him, dislodging him nearly to the edge of the poof.
His head spinning, he blinked at her retreating hindquarters as she wobbled deeper into the apartments.
"I have to pee again!"
