The first thing Luna heard upon waking was her own labored breathing. The soft rattling of chains was heard a moment later, the sound originating from somewhere above her. Keeping her eyes shut, Luna set out to scan her surroundings as best as possible.

Feeling slowly returned to her limbs and without opening her eyes she tested each leg independently, tugging them gently and making it look like the movement was natural. Near her hooves she felt a tight band of metal which clasped around her leg and with each tug she heard the soft jingle of chains above her. She felt nothing under her, yet she was suspended in the air though not by her forelegs.

A sudden pull on her bindings made Luna realize that there was some sort of holder around her barrel which dug into her flesh as she was yanked higher into the air. The princess struggled to imagine what her captor had in mind, as evidently this was part of something elaborate. Keeping her breathing low, Luna did her best to keep testing her bindings without opening her eyes and alerting her captor to the fact that she was awake.

Luna pushed a thin sliver of magic into her horn, testing if there was a limiter in place. No sudden zap of feedback assaulted her, but neither did she feel the tell tale tingle of magic resonating within her horn. This was strange in itself, but was made stranger by the fact that she was dealing with a pegasus, not a unicorn, a pony who presumably could not cast such a spell.

An anti magic field Luna reasoned, which was probably why she was being suspended as well. She ruminated further on her predicament while still trying to test her bonds and acting as though she were asleep. Seeking to find the limits of her restraints without opening her eyes or revealing she was conscious was difficult, but not impossible.

“I can tell your awake by the way. Yup, you just tensed up when I said that. You don't have to hide it. I want you to see what I have in store for you. I think you'll be quite surprised and impressed” Announced a familiar female voice.

After a moment’s consideration Luna opened her eyes to find herself in a dark room which was shrouded in shadow. The only light came from an open section in the ceiling that revealed the night sky beyond. Her suspension had angled her body in such a way that Luna could just barely see the horizon, which was near where the moon lingered.

The sight made a surge of panic course through her, the lunar princess realizing how close she had come to leaving the moon out for too long. Ignoring all the other strange stimuli Luna was experiencing, the alicorn quickly channeled her innate magic and gently pushed the moon below the horizon. Seemingly to the smug amusement of the mare who was just out of sight, the pegasus laughing haughtily.

“So the field doesn't interrupt your innate abilities, interesting. We will have to test this further, perhaps after your breaking I will have time.” Rainbow Dash exclaimed idly.

Luna merely smirked. “I have suffered a thousand years of loneliness, pain, misery at the receiving end of a nightmare made real. If you think you can truly offer me a new hell then you are more deluded than we had previously anticipated.”

The soft clip clop of hooves stopped and Luna’s ears swiveled to their last location. “What, did you not realize just how horrible being locked in the moon with a demon was? Because I can tell you right now, the nightmare was capable of far worse than any mere mortal.”

Rainbow Dash tapped her hoof against something wooden and tsked. “No, I just reached the lever is all. Now why don't you use your alicorn magic to give yourself back those pretty night eyes of yours. I want you to see what I’m going to do to you. That and I may have forgotten to steal more candles.”

Luna rolled her eyes and did as was asked of her, summoning her innate magic to allow her to see no matter how dark things got. While she did this she bemoaned that this was the end of what her innate magic was capable of, but the lunar princess was still confident of her chances of escape. Opening her eyes, Luna blinked several times before looking around as best as she could, the mare finding herself in a large, strange room.

Upon the walls were hundreds of sex toys ranging from whips, riding crops and ball gags to enormous dildos made in the shape of dozens of different monster’s cocks. The chains which held her also went all the way up to the high ceiling, and just a few feet away was a large control panel with dozens of levers. Beside which stood Rainbow Dash, the pegasus mare smiling smugly as she looked down on the lunar princess.

“Like what you see?” Rainbow Dash teased, lifting a leg and revealing her semi flaccid member which was resting against the underside of her body.

“A meagre offering, but I suppose you are only mortal.” Luna quipped.

Rainbow Dash chuckled. “Cute, but I doubt it will take more than an hour before it becomes all you can think of.”

Luna rolled her eyes. “Good luck with that, foul creature.”

“Yes well. Let's start by testing that shall we?” Rainbow Dash remarked, the mare’s lips twisting into a cruel grin.

The pegasus threw several levers, causing Luna’s legs to spread in all directions, leaving her body open, and her belly facing the floor. Next, the pony retreived a potion from a table Luna had not noticed until now, before happily skipping her way between Luna’s back legs. The princess refused to give her enemy the satisfaction of seeing her discomfort however, and Luna merely kept her head level as she felt Rainbow Dash grab her tail.

The alicorn didn't even flinch when she felt something cold, press against the entrance to her pussy. “What are you doing now?” Luna demanded.

“Just making sure you can't get pregnant. No need to thank me.” Rainbow Dash replied, the pegasus pressing the glass neck into Luna’s pussy a little more before tipping it upwards.

Thick, viscous liquid poured into the alicorn’s cunt, painting her insides, and leaving her pussy feeling incredibly warm. Though she could tell there was an aphrodisiac in the mix, it didn't feel overly strong, which only served to unnerve Luna even more. If Rainbow Dash truly did wish to break her, then it would be easier to do so if the alicorn was forced to bear her spawn while dosing Luna with plenty of aphrodisiacs.

Yet as the alicorn felt the liquid seep into her body, Luna could feel her ability to have a foal become altered somehow. She couldn't explain it, but it felt as though she would not be able to have any children, lest she first remedy whatever poison Rainbow Dash had just used on her. After the liquid had seeped completely into Luna’s body, Rainbow Dash pulled the bottle out of the alicorn’s pussy and tossed it away.

“There we are, perfect.” Rainbow Dash declared.

“Why are you doing this?” Luna questioned.

“What, you mean rape and break you? Or the infertility potion?” Rainbow Dash asked, the pegasus’ forelegs grabbing Luna’s waist.

“Both, but more so the second one.” Luna replied.

“Simple. I want to make you beg to be impregnated, to for the chance to bear hundreds upon hundreds of my foals.” Rainbow Dash declared with a smile. “The true test of a breaking is if they want it you know. Can't be sure if they are truly gone otherwise.”

“And the first question?” Luna pressed.

“Trying to get me to monologue eh? Well don't bother. I’m saving that speech for the end.” Rainbow Dash stated a second before she thrust her hips forward.

The wet smack of the pegasus’ futa cock was loud enough to be heard over Luna’s gasp of shock. “How are you so big?” Luna asked.

Rainbow Dash smirked as she ground the massive head of her dick against the entrance to Luna’s pussy. “I wasn't even half erect before. I’m so big it doesn't even go away anymore.” She explained. “Don't tell me your intimidated by it.”

Luna was glad her captor could not see her blushing, terrified face. “Of course not. I’ve had much larger than you before!” She shouted, voice wavering slightly.

“Ha, ya right. I literally had to make my heart bigger, and add more veins just to make sure I didn't pass out whenever I got a hard on.” Rainbow Dash exclaimed. “My dick is so big it should be physically impossible for me to even get an erection. I guarantee you’ve never had anyone like me.”

Luna’s response died in her throat the second she felt Rainbow Dash’s cockhead press inside of her surprisingly slippery love tunnel. “Oh yeah and I added some lube to that last potion just to make things easier. I want this first time to be quick.” Rainbow Dash exclaimed before thrusting forward.

The feeling of Rainbow Dash’s hoof sized cock slipping into her was enough to make Luna gasp in shock. The feeling of getting spread so completely robbed the alicorn of the ability to even speak, and she could do nothing as she felt Rainbow Dash’s freakish cock press deeper. The artificial lubrication served its purpose well, allowing Rainbow Dash’s dick to slip a good few inches into the alicorn in no time at all.

Luna didn't even have to look to know that she was already sporting a bulge in her mid section, one which eclipsed her small but perky breasts. Though Luna was silent, Rainbow Dash certainly wasn't, the pegasus grunting and moaning each time she pushed forward. The flap of wings and the scrape of hooves could also be heard each time that happened, the sheer effort needed to be put into the act meaning Rainbow Dash had to throw her whole body into it.

Which in turn gave Luna long enough to school her expression, and hold back the urge to scream. She was the princess of the moon, this was nothing, she would survive, and endure and if necessary simply outlive her captor. Keeping that mantra in mind, Luna relaxed her body, allowing the pegasus to ravage the alicorn as she wanted.

That slight bit of relaxation wasn't even enough to make Rainbow Dash take note, the pegasus continuing to push forward relentlessly and with little pause. Inch after inch slipped inside the mare until Luna could feel the pegasus reach a point which no other lover had managed to get to before. Only to push right past that point like it was nothing, over a foot of mare cock now stuffed into the alicorn’s overly tight pussy.

“Fuck thats good, almost to the medial ring.” Rainbow Dash muttered.

Luna’s eyes nearly popped out of her skull, the alicorn having guessed that her captor had been running out of length to push inside of her at that point. Sure an alicorn’s love tunnel was a bit deeper then a pony’s, but it sure wasn't infinite, and Luna was beginning to wonder if she could even take it all. A thought that made her wonder if that was a good idea or not, as it would at least stop the pegasus, provided she simply didn't push through such a barrier.

Shuddering, Luna glanced between her legs, and catching a glimpse of the monster which was stuffing her past the point of comfort. What she saw made Luna’s jaw drop, and a tiny squeak to slip past her tightly pressed lips. There was more, lots more, and worse yet Luna’s body was already getting warped by the pegasus’ cock, the bulge in her midsection having grown obscenely large. It was enough to make the alicorn wonder if she would ever be able to become tight again, but that thought was brushed aside.

She had much bigger concerns after all.

“Let's speed this up eh? I can take my time later, after you’re broken in.” Rainbow Dash half asked, half stated.

Before Luna could offer any kind of retort, Rainbow Dash pulled back slightly, and then slammed herself deep into the alicorn’s body. Several feet of futa cock now rested inside Luna’s destroyed love tunnel, though even still, the alicorn held firm, the mare gritting her teeth and holding back a scream. She wouldn't let Rainbow Dash take that from her, the pegasus didn't deserve her fear or rage.

“Whew. Alright, let's get this show on the road.” Rainbow Dash declared with a grin.

Her grip on Luna’s flanks tightened, and Rainbow Dash drew herself back once more before slamming back inside repeatedly. Each time she bottomed out in Luna’s pussy, the alicorn could feel the pegasus’ cock head brush against the entrance to her womb. Each time this happened she couldn't help but imagine a deep, passionate kiss, their bodies connecting in the most primal of ways.

“Fuck yeah. God I love alicorns.” Rainbow Dash muttered as she pounded the alicorn’s pussy. “No body alteration needed, just a ton of lube and go.”

Luna bit her bottom lip and ignored what was happening to her body, utilizing an age old meditation technique to control her body’s involuntary responses. She continued to focus, sticking to her technique even as the pegasus’ thrusts grew faster and faster. Until the sound of their hips slapping together was nearly constant, as was the kiss of Rainbow Dash’s cock against Luna’s cervix.

Pleasure came unbidden to the alicorn’s body, but even that was able to be dismissed by her meditation, the alicorn determined to not feel a single ounce of ecstasy. She did not want this, and no amount of alchemical medling, or her own treacherous body’s urges would change that. If Rainbow Dash noticed this, she didn't seem to care, and merely continued to hump away with ruthless abandon.

“Hell yeah. Not long now. Where should I put the first load huh?” Rainbow Dash asked before smacking Luna hard across the flanks. “I bet you’d love it up your ass.”

Luna didn't respond, the alicorn refusing to give any manner of answer.

“Silent treatment eh? I can work with that.” Rainbow Dash shrugged. “At least you aren't as bad as Mrs Cake, she was a screamer.”

Luna’s jaw clenched tighter, the urge to speak becoming difficult to ignore.

Rainbow Dash’s thrusts were now so frequent that Luna could hardly even tell the beginning of one thrust and the end of another. Not like it mattered though, her meditation technique was working well, and even as pleasure continued to burn away at the back of her mind, Luna held firm. Minutes passed, and sure enough, Rainbow Dash’s orgasm quickly approached, the pony’s grunting becoming louder by the second.

Until with one final grunt, she stopped moving completely.

Rainbow Dash’s cock flared suddenly, pulling open Luna’s womb and nearly breaking the alicorn’s concentration. Even that wasn't enough to shatter her will however, and neither was the ensuing flood of cum which erupted into the princesses’ now wide open womb. Not even the feeling of having her cervix ruined, and her belly stretched to the point of bulging obsenely was enough to shake the princess.

Nearly a minute passed, and Rainbow Dash sighed contentedly, the pegasus laying sprawled out on Luna’s back. “That was fun. You were great, if a little docile for my taste. I like a little fight after all.”

Luna resisted the urge to respond and merely lay there as she felt her rapist’s cock begin to wither, though the pegasus herself didn't move from her perch.

“Yer probably wondering if that was it.” Rainbow Dash smirked. “And I’m happy to announce that was only the beginning.”

A strange wire covered necklace was dangled in front of the alicorn’s face. “This is or was the hourglass of Ammut. It could speed up a pony quite a bit by changing the flow of time around the wearer. Now it keeps the wearer from aging while under its effects, and can allow a second target to also be sped up.”

Rainbow Dash yanked the necklace back before placing it over her neck. “Sped up how much you ask? Good question. But let me first ask you a question. How long do you think you can hold out? A month, a year, a century? What about a millenia?”

Suddenly Luna’s plan to simply wait for an opening, or wait for the pegasus’ natural end was no longer a possibility. Sure she could still wait for an opening, but it would have to be quite the good one considering what she was now up against.

“Either way we’ll find out soon enough. I figure about an hour or two of real time might pass before I’ve filled you a few thousand times.” Rainbow dash continued, her cock already becoming hard once again, her thick appendage thickening inside of the alicorn.

“My body will also never tire, never run out of cum, while yours will just keep absorbing my seed, using it to feed you until you finally beg for my foals.” Rainbow Dash nipped at the alicorn’s ear. “Then, and only then will I let time flow normally for you.”

Luna’s fear grew stronger still, though she managed to keep it in check by reminding herself that her captor was a mere mortal. Rainbow Dash would screw up eventually, and when that happened, Luna would be ready. Revenge would be hers, all she needed was time, and a chance. Two things that were inevitable in Luna’s mind, as despite all her boasting, the princess was an alicorn with thousands of years of experience.

While Rainbow Dash was a mere pony who had yet to even see half a century.

“You know I’m a little disappointed that there was no banter this time. I kinda like that you know?” Rainbow Dash shrugged. “But I guess it's like the rolling stone always says. You can't always get what you want.”

Rainbow Dash reached up, activating her necklace and causing the flow of time to shift drastically.

To an outside observer the next events happened too fast to truly be understood, with the two ponies becoming a blur of motion. The sounds they made were a cacophony of noise which no normal mind could comprehend. If you were able to speed up as well however, then things would make much more sense, as then you could watch as Luna was raped thousands and thousands of times.

Her stomach bulged over and over and over again, her silence eventually breaking and devolving into shouting, screaming, crying, pleading and finally silence would reign once more. That silence would last for a few minutes before it would be broken by the sound of moaning. Those moans would grow louder and louder, until several years later, that observer would hear something truly horrible.

Five simple words which would damn the alicorn to an eternity as a foal factory.

“Please give me your babies!”
