Waxing moon

Luna both dreaded and greatly anticipated the coming week, the signs had been building for over a month now and there was no question about it, it was time for her first heat since her return and hopefully the one where she would break her millenia long dry spell, more actually if you considered the years of her darker… episode that was spent isolating herself and consolidating power and then on fighting her sister.

Unlike the normal mares of Equestria who had to endure about three weeks or so of increased lust and lowered inhibitions somewhere in the spring or early summer, either in one long duration or spread into two to three episodes, alicorn heats were irregular both in duration, frequency and intensity. Her sister’s tended to be every fifth year or so coinciding with the solar apex with a month long build up and cooldown with the apex itself being a day where it was the most intense, Cadence’s occurred whenever sufficient love energy built up around her and lasted until she managed to in her own words “consume” it, and her own heats were the most irregular in all categories, most often they occurred during her moons apex every seventh year, but she’s had heats sometimes happen yearly for a decade, to nothing for over twenty years. And the duration and intensity tended to be inversely related, the longer the duration the weaker it was and vice versa, the balanced heats often being the ones occurring during her seven year heats and the weaker longer heats during her yearly ones, and the strongest heats being the ones that lasted for only a few days during the ones that had the longest break.

And considering her last heat was thirty years ago as Nightmare Moon had decided to perform some questionable rituals to enhance her power in preparation to face her sister on her fated return. Which promised that this one would probably be the worst she’s ever suffered.

So for this event she had planned, she had researched, she had employed her most trusted agents, acquired potions, dug up magical artifacts, and even performed one or two borderline dark rituals to make sure that this heat would be the first one since her ascent into alicornhood that was one of only pleasure.

She had also managed to bribe her sister to pull some double shifts for the event in question, one red velvet cake for each day, baked with a personal recipe and ingredients that only she was capable of producing using ancient alchemy and magics. Which meant that in about one week's time she would be relentlessly pounded into her bedding, with only breaks to allow for short restroom visits and to refill their stomachs.

Her chosen paramour for the event was to arrive tomorrow, to start his daily regimen of potions and rituals to ensure he had enough energy and virility to last. By the time her heat would start, he will be reduced to nothing but a studding stallion, slave to his feral instincts to breed, and her the only available mare to sate his needs on.

Oaken Fields stared up at the gates of Canterlot castle, the normally comforting and majestic sight suddenly feeling more like an imposing beast waiting to consume him, his four thestral escorts silently waiting for him to overcome his trepidation and finally enter the castle proper.

It was weird, the castle scared him more than what was to occur inside its wall, but that was probably due to the fact that the Princess, or at least one of her agents bearing her royal seal, had personally contacted him for this exact thing two months ago, and he had more than enough time to prepare for it. Even following the dietary and lifestyle changes was nothing in the face of the honor of being chosen for this task.

He still had a hard time believing that this was going to happen soon, maybe that was why he was so reluctant to take the final step to enter the castle. But with a deep breath he forced his emotions under control and started moving, time to make the family business proud.

Umbral Shade, personal agent to Princess Luna, stared transfixed at Oaken Fields plot and his tantalizingly heavy balls each time his tail moved far enough to reveal the frankly enormous sack, stretched out into smoothness from its fullness. Each step he took showed how fit and strong he was, muscles straining against his skin.

‘Buck, I would have loved to feel those cumtanks pump into me, mmmhmm, look at that flank! Bet I could bounce a sack of bits into the ceiling on it.’

Shade had been the one that approached Oaken Fields, since she had personal… experience so to say, with his family’s business. The Fields were one of the largest and most respected names in the studding business in Equestria, and Oaken was his family’s current pièce de résistance of stallions.

The stallion was big even by earth pony standards, the top of her head barely cresting the height of his back, he was even larger than princess Luna, but at least it left his assets at perfect eye level for her to enjoy while they walked through the castle halls. He was muscularly built, trained to be visually appealing to any hot blooded mare, broad shouldered, and the muscles in his legs rippled with each step he took, angular and masculine jawline framed his handsome face, his fur was a pleasant shade of brown akin to his namesake, and it shone in the lights of the hallway, showing the amount of care he spent on treating it. But despites his well kept looks, he let tufts of fur grow extra long on his fetlocks and chest as well as a more wild style for his mane, which was a dark brown color bordering on black, which gave him a slightly feral look. On his flank his fur was trimmed in such a way to frame and enhance his cutie mark, one row of trees on each side of a field with an acorn halfway embedded into the soil at the center.

All in all, he was a testament to his family’s and his own dedication of their business, pleasing mares and quenching heats. Shade was quite sure that the guardsmares lining the castle hallways were contemplating breaking the bank to afford his services in the future, just like she was doing right now.

Alas her eye candy charge had finally reached his destination, which left her with the task of reporting to the princess before retiring for the night, having to flip her sleep schedule to complete her missions was never fun.

As it was evening, Luna would either be at night court or attend some administrative task, which meant it would probably be an hour or so before she could discreetly inform her princess of her task being complete.

Oaken Fields had followed many strange requests that his clients made, but that came with the price tag that his services commanded, but he could honestly claim that the ones that he read off the list that was in his room, handwritten by Princess Luna, leaned towards the ridiculous. The diet thing was easy to adjust to, mostly cutting out some carbs and switching out some fruits, learning a role and script happened every now and then as well, but apparently each meal was going to be supplemented with at least one potion that would prime his body for what's to come.

He wasn’t allowed contact with any palace staff of the opposite sex, and any interaction he had with the male staff was often a minute affair or so. At first it was lonely, but gradually as each day passed he started feeling agitated and angry towards any other stallion he saw.

On top of that he had been ordered to not wash himself for the last two days, beyond cleaning up any stains or such after each meal. Sure some mares liked a stallion who had built up a bit of stink, but letting his natural odor buildup for so long was an unusual request.

Ever since day four of his isolation he has sported either a semi or a full on boner, the energy in his body refusing to subside, in fact growing tighter and tighter inside of him. And if it wasn’t for the fact that the princess orders forbade him from doing anything to relieve himself he was sure he would have baptized the royal guest quarters with his seed several times already.

She could feel it, tomorrow would be the day her heat started properly. She could already feel her nethers growing wet, her lower lips were winking every now and then, and of course the telltale warming up of her entire body, especially in her core.

She turned her focus towards the mithril case sat upon a pedestal in her room, the item within it was something Nightmare Moon had crafted and enchanted, a pendant of astral silver made to bring out the inner beast within the wearer, as well as some minor mind control and subjugation magic to bend whoever wore it to the dark beings will. Luna had cleansed the artifact of its more dark magic, and replaced it with some minor mental compulsions to encourage more sexual acts. But that combined with the extensive potion and alchemical treatment Oaken was under, would ensure that the only thing he could do was bend her over and treat her like a common whorse.

The mere thought of what was to come had her nethers dampen even further. But with discipline born out of her millenia spanning life, she forced her body under control and made sure to complete as much of her work as possible before she retired from her duties. She refused to let anything come in the way of actual release

She had to double check so that all her preparations was in order as well, each meal had been carefully planned to maximize energy recovery and to replenish fluids and vital nutrients, contraception potions were set aside for the entire week, even if she doubted she would need them considering nopony had succeeded in impregnating her or her sister for their millenias of life and multitude of trysts.

She hadn’t even talked to the stallion, let alone laid her eyes upon him and she had only skimmed the part of the report that was about his appearance, but that was for the benefit of her own sexual fantasy, that of an unknown conquering brute of a warlord subjugating her, the avatar of the night, under his sheer ferocity and carnal might, like the chaotic days before she and her sister united the tribes, where might made right and the winner claimed whatever and whoever they desired. It would be her final farewell to her days of glory, to finally embrace and integrate into the days of true harmony and peace that now ruled Equestria.
