The mare groaned and reached up to rub her aching head, only to find that she was once again bound to a table of some kind. Slowly, she cracked her eyes open, only to see yet another empty white room. Her legs were securely bound with several leather straps, though this time she was bound face up, with her body held in such a way that she was straight vertically, as if she were standing on her hind legs.

She expected to feel the sticky clinging of dry cum, but her fur was pristine and still had the same youthful splendor as before. Her mouth was a little dry but she didn't feel hungry or thirsty, and the only thing she could hear was a soft thumping sound. Looking down, she was surprised to see her teats had grown nearly four times their original size. She had originally been pretty well endowed, even lacking all the usual sag a mare her age usually had. Two small suction cups were latched to the end of her perky teats and she could feel them sucking out litre after litre of milk in a matter of seconds.

“How much milk is in those things?” She asked the empty room, more than a little perplexed by the sight of so much milk flowing from the suction cups, down a pair of tubes and into a barely visible vat of milk that lay to her right.

Her distended belly was all but gone - she still had a little pudge and she could feel her stomach was still heavy with cum, but it was nothing compared to before. Though she was a little annoyed by the fact that there were no males present for her to service, the furious sucking at her engorged tits more than made up for this fact and, for the moment, she was just about satisfied.

As time passed, she grew more used to just how massive her teats had grown and got over the strangeness of having them milked, she started to feel the heat return. It was slow at first, insidiously building up as she the pleasure of relief became more intense. She was both disturbed and a little impressed by just how much milk she was able to produce, for despite the machines working furiously for several minutes, her teats hadn't shrunk in the least - indeed the might have even grown slightly.

It wasn't long before the heat had returned fully, leaving the mare squirming and moaning, desperate to feel a male’s touch and breathe in his potent pheromones. Her body craved dick, and the longer she spent being milked, the more she missed the sensation of having her cock-starved cunt filled to the brim. Her teats felt amazing, but she knew she had been here a while as they were cramped, having been continually pumped for what felt like hours.

Her body cried out as the emptiness within it became more and more apparent. The cum in her belly had all but vanished, consumed by her strange body and now, without any cum inside her and a womb empty of cum or babies, the longing had become painful in its intensity.

With a flash of light, hope returned to the bound and frantic mare. Celestia had returned, and judging from that playful smirk on her lips, she had something new in store for the former mayor.

“Hello again, my little mare.” Her smile widened slightly as she noticed the thick reflective sheen of juices that had flowed from the mare’s cunt and down the table. “Someone has been enjoying themselves.”

Mayor Mare squirmed and whimpered. “What did you bring with you this time? More guards?” The princess shook her head. “More animals? Or a dragon? Or two dragons?!”

Celestia chuckled. “No, I did not bring you dragons. In fact, I have not brought anyone with me this time.”

The alicorn trotted forward, breathing in the potent scent of the debauched mare, a small tremor running up her spine. “You know, after I saw just how much my guards seemed to enjoy your services, I thought I would rather enjoy partaking as well. That is, if you can keep this a secret between us.”

Mayor Mare cocked her head and glanced between the princess’s legs. “I’d love nothing more than to pleasure you, but I don't think you have the, err... equipment?”

“Oh, little mare, that is just because you have not promised to keep this between us. I wouldn't want to let you see little Tia without first swearing to never tell a soul.” The alicorn smirked.

Mayor Mare’s eyes went wide. “I promise never to tell a soul. Please, give me your cock. I’m begging you!”

The alicorn slowly circled the bound mare, eying her up and down in a critical light. “I don't know, that didn't sound very heartfelt and it would be quite the scandal for everypony to find out my little secret.”

“Please, princess! I swear on my soul I will never tell another- eep!” The teat pumps were suddenly yanked from her tits, which continued to leak copious amounts of milk.

Celestia rounded the mare again and frowned. “What was that, Mayor? I didn't quite hear you.”

“I swear I’ll never tell anyone for as long as I live. Please fill my worthless body with your perfect cum. Make me your broodmare and fill every inch of me with your seed!” She cried out, straining her bonds.

As Celestia circled back around, Mayor Mare watched her smug face slowly slip back into view, and a strange, altogether different scent tickling her nose. It was faint at first, but with every step the alicorn took and every second that passed, it increased intensity and before long, Mayor Mare realized what it was and she instantly looked down, searching for the source of the scent.

There, between the mare’s legs, was the biggest, fattest cock Mayor Mare had ever seen. Sure, that was a title that seemed to be changing an awful lot recently, but the mare doubted that it would be topped any time soon. Furthermore, she wasn't even sure if a cock that big could even fit inside her. Sure, her body had changed and she seemed able to adjust to pretty much anything, but it was just so… huge. Mayor Mare lacked words to truly describe its size.

It hung low to the ground despite it being obviously fully erect; it was at least eight inches across and nearly came up to the alicorn’s forelegs. Its massive, veiny length pulsed faintly, the mottled pink and white flesh barely able to contain the sheer virility of Celestia’s cock. Perhaps most intriguing to the bound mare was just how much cum leaked from the end of it. Each step she took, another spoonful of pre splattered to the floor, leaving a thin trail of alicorn spunk wherever she walked.

She couldn't help but lick her lips at the sight. So much wasted cum was irritating, but the massive pair of beach ball-sized testes told the former mayor that it wasn't even a drop in the bucket for the powerful alicorn. I don't even care if that thing kills me, I would die happy. Mayor Mare thought, her eyes unable to be torn away from Celestia’s perfect dick.

“Oh, you like what you see, don’t you?” Mayor Mare nodded enthusiastically, a thin line of drool slipping down her chin. “You know, I don't usually play with my experiments. At most, I let the guards have a little fun... but you are different.”

“Mmmm... give it to me. Please, my princess.”

The alicorn stood before the mare, her body turned slightly to the side, allowing her to get a good view of the alicorn’s throbbing cock. “I don't know… You've already had over half a dozen births and I bet your cunt is still loose.”

The former mayor squirmed in her bindings, making her milky teats shake and leak, which drew the alicorn’s gaze. “I can tighten up, I promise! Your cock is so big, I bet it wouldn't even matter anyway.”

Celestia licked her lips and nodded, her eyes never straying from the mare’s massive, leaking tits. “That just might be… I suppose I should try out that worthless cunt of yours, but before I do that…” she licked her lips and lowered herself slightly, leaning towards the mare’s engorged teats. “I am rather parched.”

Mayor Mare squealed in delight. If nursing was half as pleasurable as the milking machine then she knew she was going to enjoy this immensely and, even if she didn’t, the promise of Celestia’s fat cock was more than enough to hold her over.

Slowly, Celestia’s descended closer to Mayor Mare’s nipple, her shaft twitching all the while. The bound mare proudly presented her leaking teats, offering them up to the princess whom leaned forward and pressed her lips against Mayor Mare’s bare skin. The instant her lips touched the mare’s body, a jolt of electricity passed through her, starling her.

“Ooooh.” The mare moaned, feeling the alicorn begin to suck at her teat, easing some of the immense pressure that had built within her body.

The alicorn’s hooves slipped forward, one propping up the mare’s teat and squeezing gently, encouraging the already-significant stream of milk to increase in intensity. Her other hoof rested against Mayor Mare’s inner thigh and even the soft caress felt like the most erotic of touches to the bound mare.

She moaned whorishly, unafraid to give voice to the pleasure she felt. Her partner seemed to enjoy her lewd moaning and began to suck harder and faster, which in turn made the mare moan louder. Mayor Mare could already feel her first orgasm begin to come - she felt a little ashamed at first, nervous about her hair trigger, but in the end she couldn't really blame herself. Celestia’s tongue circled her nipple dexterously, lavishing it in attention and pleasure. Celestia’s lips were pressed so tightly it felt like the most intimate of kisses.

Her touch, her breath, everything about the ancient mare was pleasurable - her thousands of years of experience turning even the most chaste of touches into an experience that made Mayor Mare crave more. She wasn't sure if it was the mare’s age and experience, or something supernatural about the alicorn physiology; either way, the mare didn't know or care, all she knew was that she was going to revel in the pleasure she received from the alicorn’s masterful attention.

Only several seconds into Celestia suckling at her teat and Mayor Mare came hard, her body twitching erratically and her cunt spasming, leaking a thin trail of mare cum down the table. The alicorn didn't seem to notice; her attention utterly devoted to drinking every last bit of milk the mare had to offer, though her smile did widen slightly when she felt the mare’s orgasm overpower her senses and leave her a moaning mess.

Mayor Mare would have never guessed that such minimal attention could feel so good. The soft touch, the patient suckling, she almost didn't care that her womb wasn't being stuffed full of virile alicorn sperm… almost. She didn't mind it, though, there seemed to be an unspoken promise in the way Celestia attacked her teats - something that promised that this was only the beginning, and that by the end of it, the mare’s womb would be full and they would both be satisfied.

The pressure had subsided relatively quickly and the mare found both of the soft and gentle hooves of her lover squeezing and kneading her teat, trying to milk her for every last drop. The waning stream of milk redoubled under the intense but gentle squeezing, Celestia’s masterful hooves seemingly knowing the exact places to press in order to get more milk without applying too much pressure. Mayor Mare idly wondered how many times the alicorn had done this. A hundred times, two hundred? Thousands? She couldn't know, but she immediately felt immensely honored to receive the attention of such a perfect lover.

It didn't take long for her first teat to begin to empty, the intense pressure that had built inside slowly dissipating to more manageable levels. Mayor Mare knew her body wouldn't let her rest for long and it would only be a matter of minutes before her teats once more grew fat with milk, but for now, she was mercifully relieved of the pressure that had plagued her since she had first awoken. Even still, Celestia’s lips lingered, her hooves caressing Mayor Mare’s soft and sensitive flesh.

She didn't suck quite as hard, nor did her hooves press nearly as much as before, and the former mayor blushed due to the strange level of intimacy. Where before there was passion, a hunger in the alicorn’s eyes that drove her to drink every last drop, now there was patience and affection that Mayor Mare didn't expect.

It didn't last, though, and soon the alicorn gently pulled back, bringing Mayor Mare’s breast with her until she released her lips with a resounding pop, allowing her now slightly empty breast to fall to its spot between her legs. Celestia licked the milk that had dribbled from her mouth in a long, exaggerated motion, all the while looking Mayor Mare directly in the eye.

The mare couldn't help but shiver; she knew the act was another promise, the alicorn would drain her massive teats of every last drop they had to offer before turning her attention to the mare’s empty womb. Then she would fill Mayor Mare’s worthless body with more cum than she could have ever hoped to contain if she was a mere pony.

The thought was exhilarating and the former mayor was nearly vibrating in her bonds by the time the hungry alicorn descended on her other breast. A shuddered moan escaped the bound mare’s lips and she couldn't help but sigh in relief, only to eep when she felt something pinch her sensitive nipple. She glanced down at the smirking alicorn who had nipped her breast, making Mayor Mare giggle at the sight.

A part of her felt like she should be angry at the princess but she couldn't muster the effort to do something so monumental. In Mayor Mare’s newly changed mind, it was little more than a playful gesture, one that she couldn't help but feel aroused by. Celestia’s soft teeth teasingly brushed across the mare’s incredibly sensitive nipple, all while she insistently sucked down more and more milk.

The alicorn’s soft and gentle hooves grew insistent and teasing, with one brushing close to the Mayor’s gaping cunt while the other pressed firmly on the former Mayor’s teat. The bound mare arched her back as far as it could go and let her head fall back in ecstasy as yet another lewd moan graced Celestia’s ear. Her pet had well and truly given up, and even the alicorn’s teasing and the tiny bit of pain the mare felt was met with an immediate surge of arousal.

Mayor Mare was in heaven; a part of her new physiology was rewarding her immensely for both successfully birthing and now nursing. Her body didn't know that her milk was going towards an ancient alicorn who in no way required the nutrient-rich liquid, but it didn't know that. All it knew was that it had been knocked up successfully and was now giving its new children the sustenance they need.

Pheromones that had been powerful and enchanting before were growing more and more captivating by the minute. The bound mare was now quite familiar with the burning need to be bred that flared within her body, but even her experience had nothing on the heat inside her. This pony, this goddess, was the perfect mate and Mayor Mare’s body was doing everything it could to encourage the pair to breed like rabbits and fill her womb with a new batch of life.

The gentle sloping sound of a new burst of pre splattering against the ground was met with a fresh surge of pheremones. The alicorn’s production was staggering and a small pool of precum had formed on the floor between her legs. The scent of the virile seed was the best thing Mayor Mare had ever smelt and a tiny part of her wanted to roll around in it and cover herself with the stuff.

The slow but forceful sucking at her nipple began to wane as her impressive production had begun to be consumed by the alicorn’s thirst. Celestia nipped at the mare’s nipple and lamented the slowly dissipating supply of milk - despite the many, many litres stored in a container behind the mare, it just wasn't the same. If the alicorn was being honest with herself, she had always loved to drink the milk of her lovers directly from the source and she, in turn, reveled in nursing the very few times she had ever given birth... but that was a story for another time.

This time, rather than give up when Mayor Mare no longer had any milk to give, Celestia sucked insistently, trying to pull every last drop from the mare’s now slightly less enormous teats, even going so far as to squeeze the breast with both hooves, which managed to get a few more drops of precious milk, but that was it. The feeling of emptiness was mind blowing - it was as if her body was rewarding her for getting drained completely and Mayor Mare screamed to the heavens as another for potent orgasm cascaded through her body.

The small river of mare cum that ran down the table surged as the mare came hard, adding to the steadily growing lake of female juices that spread from beneath her. The sound of unbridled passion was music to Celestia’s ears and there was something so very primal about it that moved her to action. With one last kiss at the bound mare’s , breast Celestia reluctantly pulled back, letting the now slightly bruised nipple to fall.

Mayor Mare hardly even noticed this, however; her body was demanding more and she could not resist, but there was simply nothing there. That didn't stop her from dry humping the spot where her partner should be. She moaned and twisted within her bindings, the tingling in her body rising to the occasion of mating with such a powerful specimen.

The pheromones didn't only effect Mayor Mare, however, and by now, Celestia’s fortress of a mind was filled with thoughts of all the debauched things she wished to do to the bound mare. She knew the hybrid’s inherent magic and natural chemistry was affecting her, but rather than put up guards to these things, she breathed deeper. She was going to well and truly cut loose after all these years and she was going to enjoy every last second of it.

The alicorn rose up to her full height, standing on her back hooves and bringing her forehooves down on the table on either side of Mayor Mare’s head with a firm bang. The sound jarred Mayor Mare from her lust-filled madness and made her blink in confusion as the light was suddenly blotted out by a huge white shape that utterly dominated the entirety of her vision. The only thing she could see was the glint of the alicorn’s eyes, which sent a thrill down her spine.

Celestia was always utterly dominant - her every step said to all around her that she was in control. Every word spoke of her complete dominion and even the most resistant of ponies found themselves unexpectedly bending the knee to the powerful alicorn. This was something else entirely; the alicorn had Mayor Mare at her complete mercy. When she had first given in to her new role in life, she felt as though her body was not truly hers anymore, it was merely an object for Celestia to use to birth as many creatures as she desired. Now, with the alicorn’s body so close and her position so commanding, Mayor Mare was absolutely certain that the monarch controlled even her very soul.

“I am yours. Please, take me, my princess.” The whore whispered huskily.

The alicorn merely snorted in amusement. “You were always mine. And now you will truly step into your role as my cum dump.”

Mayor Mare shuddered in delight, relishing in the complete lack of control she had. The huge flat head of Celestia’s cock lurched up, smashing against Mayor Mare’s relatively unused asshole. Sure, a few of the stallions had fucked it to their heart’s desire, but it had not faced the sheer amount of abuse that her cunt had and, despite Celestia’s shaft being lubed by her copious pre, it was not enough to penetrate the mare’s back door.

The alicorn growled in annoyance, drawing a whimper of supplication from the mare who craved to satisfy her princess, her goddess, her everything. Mayor Mare pressed down and closed her eyes, willing her body to be able to take her owner’s massively endowed cock. Celestia recoiled, pulling back a few inches before expertly thrusting forward, slamming herself against the mare’s backside but still not penetrating. The former mayor could feel her body begin to yield and her hole ached to be filled, but it was simply too big to fit.

The next brutal thrust was met with a desperate counter thrust by the mare who pushed down with all her might. When their bodies connected this time, Celestia’s flare managed to not only slip inside, but even surged several inches deep, which in turn drew a moan from the pair, though where Celestia’s was still a little reserved, Mayor Mare’s was an unabashed celebration of their coupling and she cried to the heavens.

Celestia’s muscled hooves dug into the table and gripped it tightly before thrusting forward again. The bound mare’s cry raised a few octaves as she felt the titanic invader slide deeper into her guts, making even the changeling hybrid to begin worrying if she even had the space inside her for such a mammoth dick.

Whether she did or not was irrelevant for she knew she would pleasure the alicorn to the best of her abilities even if it damaged her seemingly elastic body. The cock twitched suddenly, sending a spurt of pre deep into the bound mare’s body and further lubricating her hole. Despite the added lube, the alicorn did not thrust forward, and even stopped altogether, looking down at Mayor Mare and smiling strangely.

“How does it feel to take the dick of a goddess?” She asked, her lips turning up to form her now familiar smirking smile.

“It feels so good! I’m so full, but there is so much left yet. I don't know if I can take it all, but for you, I will take every last perfect inch.” She whispered back, much to the amusement of the immortal sun princess.

“Don't you find it funny that mere hours ago you would have ranted, raved and begged for this not to happen? Is there even a shred of that Mayor Mare left in there?” Celestia stared down into the mare’s eyes, searching for any lingering patches of resistance.

But there was none - the mare known as Mayor Mare was no more. In her place, a new creature had risen from her ashes, and this one would never even dream of resisting the powerful alicorn. “No, my princess. I live to serve you wholly and completely.”

A faint flicker of disappointment passed through Celestia’s features, but it was gone in an instant. “How unexpected.”

Her hips surged forward without warning, reminding the bound mare that the alicorn’s titanic cock was still inside her. The sheer size of the alicorn’s endowment made every thrust difficult, but with the unbridled power of a god, not even her tight hole could resist for long. The alicorn didn't even seem to notice just how vicelike Mayor Mare’s asshole was and, despite the crushing tightness, she didn't even flinch.

The bound mare wanted to loosen up and her body was tingling all over from the effort, but it was simply too large and too fast for her to catch up. She paled at the thought of her overly tight hole causing pain to the princess, but one look at her features showed no hint of annoyance or suffering. She kept focusing on that regardless - even if the princess didn't show it, Mayor Mare was sure her body was not perfect for her needs and she would be damned before not doing everything she could to pleasure her goddess.

Celestia slowly worked her way deeper into the mare’s body, every thrust distending her belly further and stretching her hole nearly to the breaking point. Another thrust and the massive bulge inched further up Mayor Mare’s body; her hips had thankfully already adapted to pushing out large children. If they hadn't, well, she wasn't sure if she could even hope to take the alicorn’s massive head.

Over time, even the faint pain the mare felt began to subside and, as the alicorn thrusted again, she could feel her body finally begin to adapt and relax its tight grip it had on Celestia’s cock. The alicorn breathed a tiny bit easier, something the astute hybrid did not miss. It was small, but it was a sign the usually reserved pony was enjoying herself, and Mayor Mare loved it.

She loved it almost as much as the sight of Celestia’s gargantuan cock surging up her stomach, spreading the inner reaches of her ass and drawing a squeal of delight from the bound mare. She could feel Celestia’s medial ring bang against her hole and, despite the fact that it couldn't slip inside, she was still proud. She was nearly halfway there and, even if it wasn't as far as she wanted to be, it was still better than her old, unaltered body could ever dream of reaching.

Mayor Mare wanted to run her hooves down the bulge in her midsection, to egg the princess on and to urge her deeper. She wanted to feel the alicorn’s dick violating the deepest reaches of her body and claiming them forever more for her one true goddess; Celestia.

The alicorn grew insistent, pulling back and thrusting hard, battering the mare’s still-adapting hole and trying to squeeze her medial ring into the mare’s body. Mayor Mare was trying to aid in the princess’ efforts, but there was little she could do other than push down against it as much as she could. After the third attempt to squeeze her medial ring into the mare’s now ruined hole, the alicorn growled in annoyance and nearly pulled out of the bound mare’s hole completely...

Only to slam herself back inside with all the force of a charging bull. Mayor Mare threw her head back and screamed in ecstasy, feeling her goddess’ length plunging into her with enough weight behind it for her medial ring to slip inside along with a few extra inches. Another screaming orgasm rocketed through her mind and Mayor Mare tasted the unbridled pleasure of feeling the most important pony in existence filling her insides.

She knew it was only a taste of what would happen when she felt her goddess’ cum filling her womb, but for now it was enough... A sentiment that Celestia didn't seem to agree with, however, and she was quick to pull out slightly, her medial ring slipping out of the mare only to pop back inside, teasing her with that delicious feeling of being stretched that she so loved. The alicorn teased her like this a few times before making her mind up and thrusting back inside the mare, filling her utterly and nearly bottoming out inside her.

A few more thrusts was all it took to finally feel the entirety of her cock resting inside the deepest reaches of the bound mare’s body, who in turn came again, one orgasm bleeding into another as her guts were stuffed full of alicorn cock. Seconds passed without Celestia moving; her head was back and she took a slow, deep moan of pleasure, enjoying the feeling of having her cock buried in someone who could actually take every last inch of her throbbing length. It was a feeling she had not experienced in what seemed like millennia.

Mayor Mare was content to remain like this until her seemingly endless orgasm finally died down and she was able to catch her breath. With the alicorn still unmoving, the mare took the time to look down at the sight of her body and revel in her accomplishment.

Every last throbbing inch of the princess was inside her, and she could feel those enormous, heavy balls of hers resting firmly against her. More important than even that, though, was the odd sight of her belly. Celestia was long, thick, and her cock seemed to reach up nearly all the way past Mayor Mare’s ribs. She didn't know how such a deep penetration was even possible, but again, that didn't matter.

Celestia stirred and Mayor Mare quickly withdrew her head, searching the alicorn’s eyes for a hint of her desires. A strange, formerly hidden intensity seemed to burn within and the alicorn’s usually calm eyes belied an intensity the former mayor had not seen yet.

She couldn't help but shiver at the sight; Celestia had finally allowed herself succumb to her lust and something told the mare that she would love every second of what happened next. The usually talkative mare grit her teeth and pulled out suddenly, dragging her massive cock out of the mare so fast that she hardly had time to whimper before she felt the alicorn’s head slip free from her clutching depths with an audible pop.

Her asshole was left gaping, her ruined hole trying to close but unable to due to the sheer amount of abuse Celestia’s titanic cock had wrought. Mayor Mare opened her mouth to speak, desperate to ask why the princess had stopped so suddenly, but the alicorn threw her hips forward and, with perfect precision, managed to penetrate Mayor Mare’s aching, wet cunt with a single thrust.

The second she felt her goddess’ head slip inside and surge deep into her body, Mayor Mare felt another orgasm coming on, but she refused to be rendered a quivering mess so soon. She pushed herself down hard, using what little wiggle room she had to desperately push more of the alicorn’s massive endowment into her now utterly destroyed hole.

She couldn't hold on for long, though, and the instant she felt Celestia’s medial ring slip inside her, she lost it. Her cunt tried to clamp down on the marecock inside her, but her hole was too loose to offer more than a small squeeze. The alicorn’s cock was now thoroughly coated in mare cum and Mayor Mare’s hole was lubricated as much as physically possible.

Coupled with just how thoroughly wrecked her cunt had been from the beasts, the guards and the births meant that even the titanic Celestia hilted the mare in seconds. Her cock simply bashed through the weak barrier her womb gave and slipped inside. Celestia’s heavy balls smacked into Mayor Mare’s ass audibly and she could feel every last throbbing inch of the alicorn’s cock nestled inside her cunt, making her orgasm rocket into new heights of pleasure that even being fucked with three enormous stallion cocks had not reached.

With her length now firmly inside the bound mare, Celestia seemed to relax and let out a low sigh of relief, even chuckling at the odd faces Mayor Mare made as she came.

“Did you enjoy that, my pet?” She asked with a smirk.

Mayor Mare was not capable of speech, so she simply nodded weakly.

“Really? I didn't think you would even notice with such a sloppy loose cunt like yours.” Celestia chidded, wiggling her hips slightly and shifting her length around inside Mayor Mare’s pussy, stirring her up.

“You feel so good... please, fuck me and give me your cum.” Mayor Mare whispered.

Celestia smirked and ran a hoof down the massive bulge that her cock made in the mare’s midsection. “I don't even know if I can. You’re so loose I can hardly feel it.”

Mayor Mare whimpered pathetically, shutting her eyes and focusing her attention on her pussy and trying to squeeze down on the turgid length. Celestia could feel the mare’s feeble attempts to grip her cock, but she was simply too loose for it to be even noticeable. The alicorn tsked and ran a hoof through Mayor Mare’s mane.

“Even when I give you what you desire most you still cannot pleasure me.” She smirked. “Pathetic.”

“No! I can do it! Just give me a second.” She squeezed her eyes shut tightly, trying desperately to make her loose cunt to tighten up and give her princess the pleasure she so deserved.

Celestia wiggled her hips in long, slow motions making her cock stretch and distort the mare’s cunt and completely negating any chance she could adapt. After a few frustrating seconds the mare slumped in defeat, a tear rolling down her face.

“I can't do it. I’m so sorry Celestia. I-I…”

“Shh, settle down, little mare. It’s okay.” The alicorn wiped away her tears.

“B-but I couldn't…”

Celestia’s smirk drooped a little; the mare was obviously quite distressed by what she saw as failure. “How about this - I can give you a chance to redeem yourself. It's going to be tough, but if you can succeed, I will give you my seed.”

Instantly, her eyes lit up. “R-really? You mean it?”

Celestia couldn't help but smile. “Yes, but we are going to need a new position first. Something a little more comfortable.”

Mayor Mare nodded, watching as Celestia undid her bindings and let her fall slack on the table, only to be caught by the massive length still inside her. The mare’s limbs instantly wrapped around Celestia’s barrel and she buried her face in the alicorn’s fur, breathing in her potent scent.

The alicorn couldn't help but grin; there was something almost innocent about the bound mare now, something she didn't have before. Regardless, she promised the mare a chance to earn a belly full of alicorn cum and she couldn't back out now even if she wanted to. She wanted this almost as badly as the hybrid needed her womb filled with life.

Celestia couldn't bring herself to pull the mare from her cock; the way she snuggled against her barrel, breathing in her scent while gyrating her hips was equal parts adorable and sexy. Instead, she placed a hoof against the mare’s back, holding her in place while she dismounted from the table. The alicorn tried to ignore the pleasurable sensation of the mare’s fat milky teats pressing against her, leaking a thin line of milk and matting her fur.

She walked around to the other side of the table, the now unbound mare not even flinching and even managing to work herself up and down Celestia’s shaft a few inches on every step. With a flash of her horn, a small mountain of pillows spilled out over the tiled floor, creating a more comfortable spot for the pair.

With a spring in her step, the alicorn launched into the air and, with a twist of her wings, spun around in mid-air, then she gracefully extended her wings and floated down into the pile of pillows. Mayor Mare held on tight all the while, desperate to not lose her place as Celestia’s cock sock. Celestia extended her legs and sighed, squirming slightly to get into a more comfortable position on her back with her toy still firmly latched to her belly, rather confused how she was now on top.

Mayor Mare blinked and looked around, only now realizing that she no longer needed to cling so tightly to her goddess’ body for fear of falling off. Celestia noticed her surprise and smirked, running a hoof down the mare’s face. “Surprised I'm this graceful?”

“N-no! Of course not! It’s just... I never thought you’d let me…” She looked down, gesturing to their position. “Like this.”

Celestia shrugged. “This is your chance to prove yourself. If you do well, maybe I’ll use that silly pair of portal panties Luna gave me and keep you as my personal cock warmer.”

Mayor Mare’s eyes twinkled and her cunt squeezed down on the cock still resting inside her. “Really? You mean it?”

“Tick tock, little mare.” Celestia said with her trademark smirk.

Said little mare gasped and instantly got to work, jumping to her hooves and pulling herself up and down Celestia’s length. At first it was slow, the mare reluctant to pull back more than a few inches, her desperate desire to be filled impeding her abilities. When Celestia didn't up and disappear in the first few seconds, though, she pushed past her reluctance - she had been given a chance, one she swore she would not waste.

The sheer logistics of the alicorn’s cock made things difficult and would require more finesse than the former earth pony thought she was capable of, but that wouldn't stop her. She shifted her hooves, setting them wide apart and allowing her more space to pull forward suddenly, heaving herself up the massive cock before throwing her weight back and plunging nearly all the way to the base.

The effect was immediate and Celestia let slip the smallest of moans as a reward for the mare’s actions, an act the broodmare found immense pleasure in, eliciting a tiny squeal of joy. She didn't forget what she was doing, though, and quickly dragged herself back up the princess’ monstrous cock. Back and forth, over and over, the mare brutally fucked herself on the alicorn’s impressive endowment.

Celestia seemed tense at first, but as time went on, she relaxed and even ran a hoof down the mare’s side, even stopping her long enough to sneak in a quick kiss. It was small, short, and lasted only a second, but the mare felt oddly invigorated by the kiss despite how chaste it was. Her limbs that had grown oddly heavy felt rejuvenated and she threw herself into the act with renewed vigor.

The implacable alicorn even dropped her seemingly perpetual smirk and let her head fall back and her eyes close, simply enjoying the sensation of the mare riding her cock. She wasn't as tight as she would have liked, but it was still immensely pleasurable and the bound mare seemed to catch on to more and more of the alicorn’s turn ons as time went on.

When their hips met, the mare strayed there for a moment, squishing her milky teats against Celestia’s far less endowed pair. The alicorn’s face gave no hint of her enjoyment, but the way her cock twitched ever so slightly was all the acknowledgement the mare needed to make sure she did that every single time. The mare herself even relaxed over time; the odd position of being on top felt bizarrely wrong to her. She wasn't meant to be in control, especially when with a literal goddess.

As time passed, an odd memory popped up - one of her old assistant, Svengallop. She remembered how she was getting a massage one time and had made the odd stallion fuck her in the ass. Not a particularly memorable experience; the stallion felt disgusted by the act and Mayor Mare revealed in the feeling of control. Even though he was on top, he was never anything more than a toy... which was exactly what she was now; a toy, a slave to be used and abused as her goddess deemed fit.

When she truly realized just how little control she had and how utterly Celestia controlled her even when the mare was on top, the final wall fell and she came hard. Some small part of herself had been holding back, not allowing her to truly enjoy herself due her misconception that she was in charge. With such a perfect, and utterly dominating mare like Celestia, though… She was never in charge.

Something still worried her, though - it was small, selfish, and she didn't want to think about it, but the thought remained regardless: what if Celestia abandoned her after this? What if this was her first and only taste of her perfect cock? The thought plagued her worse than she cared to admit, even to herself. She was well and truly addicted already, craving it intensely. The thought of going with it it for the rest of her life…

A shiver of terror ran down her spine and she stopped mid movement, drawing the eye of her goddess. She lowered her head submissively and quickly got back to work; her movements were too quick, and lacked the grace they usually had.

“Is something the matter? I was rather enjoying this sloppy cunt of yours.” Celestia said with a chuckle.

The mare gulped. “No, my goddess.”

Celestia watched the mare continue to shift up and down Celestia’s cock, but her heart clearly wasn't in it anymore. Finally, the alicorn rolled her eyes and grabbed the mare at the peak of her thrust, pulling her close. “Tell me what is on your mind, little cumdump.”

Mayor Mare sighed and looked away. “It is a selfish, worthless thought, but I was just hoping that you would…” She winced. “Use me more. I mean, after this, anyway.”

The slow, oddly deep chuckle of the alicorn drew the mare’s eyes up towards Celestia’s grinning face. “How about I put forth a challenge. If you can succeed then I will create a portal directly to your cunt so I can use you as my cock sock whenever I want. If you fail, though, I will not return to use your worthless cunt for an entire year.”

The mare gasped, her mind turning a thousand miles an hour as she realized the weight of such a challenge. She couldn't give up yet though, right? The potential rewards were… tantalizing. “W-what would you have me do?”

“I’ll give you one minute to get me off.” Mayor Mare scratched her chin, unsure if she wanted to accept such a bargain. The princess had remained relatively unmoved during the last several minutes and- “fifty nine, fifty eight.”

All such thought fled from her mind and the mare flew back, impaling herself once more on the alicorn’s endowment, the flared head of the alicorn’s cock distending the mare’s belly from base all the way up to just under her ribs. All her focus was on her cunt and her inner muscles went into overdrive in an attempt to squeeze the delicious cum from the alicorn. Though still battered from the recent births and Celestia’s unnatural size, she managed to squeeze down a little on the massive invader.

She didn't end there, though, and she focused on her teats as she rode the alicorn, willing them to grow and fill with milk at a faster rate. Within a few seconds the mare’s teats ballooned to their former size and, the next time their hips connected with a wet slap, her lactating tits squirted a small stream of milk, soaking the alicorn’s coat.

The effect was immediate; the alicorn’s cock twitched, her balls seemed to churn with fresh seed and even the alicorn’s face had the smallest hint of a smile on it. All of that meant her choice was a resounding success. She wouldn't, no, couldn't stop there and, as she rode the mare, she sped up more and more. Sounds of her wet, loose cunt slamming into Celestia’s hips were barely audible over her loud, passionate moans. She didn't hesitate to let the world know just how much she loved the feeling of the alicorn inside her.

Mayor Mare knew the alicorn enjoyed that, but it still wasn't enough to assure the hybrid that she would win this little challenge and, with only thirty seconds left, she desperately searched her mind for what more she could do. It was a difficult task, though, as the alicorn never really let on as to what she enjoyed. The mare had to rely on an errant twitch here or a tensing of a muscle group there.

“My goddess, please fuck this worthless hole of mine! Let me feel your power, I beg of you!” She begged, all while she made the biggest, saddest puppy dog eyes. The alicorn stopped counting down and seemed to think about it. Mayor Mare brought a hoof up to her chin and ran it down her body, all while she continued to ride the alicorn. “Oh please, my goddess, my slutty pussy yearns to taste the punishment it deserves.”

The alicorn’s nostrils flared and she couldn't help but smile. “So be it, little mare. Don't say I didn't warn you.”

Before the slave had a chance to even think about what the alicorn’s cryptic words might mean, her backwards thrust was met with what felt like a charging bull. Celestia’s back hooves were spread wide and she had thrusted her hips up with such tremendous force that Mayor Mare’s teats erupted in a spray of milk.

Somehow, the mare had remained standing, even as the alicorn’s hips flew back and then slammed into her once again. She winced from the pain, but it was a small, petty thing in the face of just how much pleasure the brutal fucking dished out. By the third thrust she managed to adapt to the sudden roughness and even pushed back slightly. The fifth thrust didn't feel as hard as the first and Mayor Mare could feel her ass begin tingle and grow, adding more padding for the mare’s thrusts.

Soon enough Mayor Mare was able to muster the strength to push back, meeting their hips halfway and drawing a surprising moan of pleasure from the alicorn. She knew what must be done and she threw herself literally and figuratively into the act, throwing her weight back against the mare’s thrusts with all the strength she had.

Their movements were sloppy, irregular, but that changed quickly, a strange harmony arising from the frantic, powerful thrusts. Mayor Mare could hear the alicorn’s breathy moans between the seconds she counted down. “Thirteen, twelve, eleven-”

Panic flashed through the mare’s mind and, for a split second, she allowed thoughts of defeat to fill her head. She pushed them out quickly, just in time to throw her weight back, not missing a beat. The mare had drawn close to orgasming yet again but she held back for a moment, fearful that it would make her concentration flicker. With only a few seconds left, she looked up to Celestia, hoping against hope to see some sign that she had been doing well.

The alicorn’s face was impassive as ever and, with only two seconds left, Mayor Mare feared the worse, until the alicorn sighed suddenly and a look of utter pleasure crossed her features. She stopped counting down and her body relaxed after thrusting one last time. With her cock now buried into the deepest reaches of Mayor Mare’s womb, Celestia’s cock twitched once and erupted with an explosive burst of cum.

The hybrid’s eyes grew wide, shocked by the sudden orgasm that not even she saw coming. She hadn't even felt Celestia’s cock flare inside her - her bruised and battered hole too stretched to even sense the sudden shift. By the time the mare was aware of what was happening, her belly had already begun to distend, hiding even Celestia’s massive flare in seconds.

She couldn't help it; she came, hard. She could hear herself screaming Celestia’s name in ecstasy, but she wasn't even conscious of the action. By the third jet of cum, her belly grew large enough to press against’s Celestia’s milk-covered fur, pressing against the alicorn’s muscled stomach. Somehow, Mayor Mare had the presence of mind to stay standing as her powerful orgasm washed over, her but it was difficult even for her.

Darkness pressed in from the edges of her vision and, for a split second, she felt nothing, only to wake with a start. It had felt like seconds, but clearly it had been much longer that she had been out as her womb was so packed full of cum that not even her adaptability and recent births could help her in that regard. Celestia’s cum was also different - where the other animals and stallions’ cum seeped out of her and was more watery, the alicorn’s was thick, heavy, and more of a cream than what she imagined cum would be.

Even with being packed so completely, she felt very little dripping out of her and she was both amazed and relieved to feel that she had managed to keep almost every drop inside her hungry womb. It was at that moment that she realized Celestia was looking her in the eye with an odd expression. “You in there, little slut?”

Mayor Mare squeaked in surprise. “Er, yes?”

The alicorn chuckled, her cock still spasming weakly and adding a few more hefty loads of cum to her already full womb. “Good. Thought you overdosed on lust again, but it seems like your body has gotten used to that.”

The mare nodded weakly, looking down at her frankly enormous stomach. If she was standing on her own hooves, her belly would have probably fallen all the way to her knees and would have made walking very difficult. The sight of such a potent load filling and completing her was the single greatest sensation the mare had ever felt and she was dimly aware that she was orgasming yet again. Though the feeling was strangely distant, as if her mind had become so overwhelmed with pleasure that it was hard to even process anymore.

“Did- I...Did I win?” She whispered, unable to tear her eyes away from the size of her stomach.

Celestia smiled faintly. “Yes, you did. In fact, you did so well I’m promoting you to royal cock sock.” The alicorn beneath her took on a bizarrely regal expression. “Congratulations, little slut. You hold a title that hasn't been used in over three hundred years.”

“Yay.” Mayor Mare muttered, exhaustion quickly sapping the last of her strength and making her legs begin to wobble.

“Every night I will use you as my personal cock warmer and every day you will give birth to a new litter of my children.”

“Thash nishe.” The broodmare slurred, stumbling slightly to the right.

Celestia giggled, and with a flash of light she was gone, allowing the broodmare to fall into the mound of pillows, instantly falling asleep. Despite the fact that she had fallen straight down onto her belly, not a single drop of cum slipped from the mare’s cunt. The alicorn’s cum was too dense and the seal it had on her womb too strong.

Standing above the now-slumbering mare, Celestia smiled widely, without a hint of malice, or ill intention. She gently turned the mare to her side and propped more pillows under her before kissing her on the nose. “Good night my pet, sweet dreams.”
