Sisterly Games

The first thing that Celestia noticed about the second chamber was that there was no more magical barrier. Immediately, she rushed over to Luna and opened her arms to wrap her sister in a tight hug. Her large, white wings also rose to engulf the two of them as Luna’s arms weakly came up to embrace her in return. The scent of scat clung heavily to the younger alicorn, and Celestia’s nose wrinkled in distaste. But she held her sister firm in reassurance.

“Are you okay?” she asked quietly.

Luna nodded against her. “We will be fine,” she replied as she pulled away. “Let us focus on whatever hell this bug shall spring upon us next.”

Celestia nodded in response, her eyes lingering on Luna’s brown-tinted lips as the younger alicorn stepped away. She could only imagine what her sister had just gone through… the taste alone must have been… Celestia shuddered to even think about it. But there was no point in dwelling on it now, they had a second challenge to conquer.

At the far end of the room stood two stone tables. Cautiously, Celestia approached the one closer to her and gazed upon the objects presented. There were three ornate keys, each with a number carved into its handle. “Zero, one, and five,” Celestia muttered quietly as she lifted one up to read the inscriptions on her set of keys more closely.

“We have two hundred one, two hundred thirty-seven, and three hundred four,” Luna replied from her own table. She glanced over to meet her sister’s gaze. “What could they possibly mean?”

Celestia simply sighed in response. “I’m sure we will find out soon enough.”

“The second challenge is as follows,” Chrysalis began, right on cue. “Before you there are three keys, each with their own unique number. The correct key is the one inscribed with the number of suitors the other has taken in the past.” Both alicorn’s eyes widened at the challenge. Celestia’s cheeks flushed slightly red, knowing how high her own number was. “You may not help each other in any way. If you do, you will lose this challenge and face punishment. You have three minutes to make your choice, starting now.”

“Huh,” mused Luna. “How juvenile.”

Celestia eyed her sister, who was currently staring intently at her own set of keys. “Indeed,” she replied. She had not known Luna to ever take a partner prior to her banishment - a testament to how lonely the alicorn actually had been. And, to be honest, there had not been much time since she had returned, and she had not ever seen Luna with anypony during these short few years. It had to be no one, right?

Herself on the other hand… well that was a different story. A blush blossomed across her face as she tried to determine what her own number was.

Luna glanced between her sister and the numbers on top of her own set of keys, taking note of the rosy tint that graced her pale cheeks. A thousand years was certainly a long stretch of time, but two hundred suitors in that time? Maybe even three hundred? That was quite a lot of… action.

But looking back, even before her banishment, she could recall her sister being quite promiscuous with the nobility of the time. Such was one cause for her extreme jealousy after all. These days, Tia certainly appeared to be more reserved, but Luna had still managed to catch a few mischievous glances that her sister shared with many of those around them. If this behavior had persisted during the last millenia, she supposed it was better to guess high rather than low.

“Have you chosen?” Luna asked her sister as she settled on her own answer.

Celestia nodded.

“Excellent!” exclaimed Chrysalis. “And with a whole minute to spare! How exciting! Luna, what is your answer?”

The darker alicorn took a deep breath, bracing herself before she responded with, “Three hundred four.” She quickly stole a glance over at her sister, to see the rosy blush on her cheeks turn an even darker shade of crimson at her answer.

“Mhmmmm,” hummed Chrysalis’s voice. “Yes, that would indeed be correct! Your sister is quite the royal slut, isn’t she?” Her laughter rang out following her vile remarks, and Luna growled. Celestia, on the other hand, simply blushed even darker and looked down. “Now for your answer, Celly.”

“None,” Celestia answered timidly. “Zero.” She barely needed to glance to the left to see the look of hurt on her sister’s face to know that she was wrong.

“Ooooooh, I’m sorry,” the changeling queen hissed out. “That’s not quite right. The answer we were looking for was ‘one.’ I know you’re a bit looser than most, Princess, but it’s a bit harsh to think so little of your sister’s attractiveness.” Her tone was crudely chastising, and Celestia’s eyes narrowed.

“You are cruel,” she replied. “You know my choice had nothing to do with how beautiful Luna is.”

Chrysalis’s cackling laughter rang out in the room. “We get it, you have the hots for your sister. That doesn’t change the fact that you were wrong, wrong, wrong.” Celestia huffed in response, but refused to otherwise dignify the crass comment with a response. As her laughter died down, the changeling continued. “Now, since your sister was so rude with her assumption, I believe it is only fair if you get to choose her punishment, Princess Luna,” Chrysalis announced as if it were a prize she had won.

Luna could practically feel the glee dripping off of the changeling’s voice. “We shall choose no punishment then,” she quickly stated. There was little chance that it would work, but she would try anyway.

Chrysalis’s laughter predictably echoed out into the room. “Haha! Perhaps I should be more clear. You have the opportunity to select which punishment your sister will get,” she explained. “Are you ready to hear them?” Luna scowled in response, but Chrysalis took that as the go-ahead to list them. “First, you may have your sister finish what you started in the previous punishment and dispose of the remaining shit. Second, you may subject her to an altered version of your punishment and feed her your own helping of steaming shit. Or third, you can add a number to your sister’s already prodigious body count. You have one minute to decide.”

Her eyes drifted over to Celestia to see a stoic look on her sister’s face. The elder princess had strategically kept her reactions to the proposed punishments in check with her best, political poker face. Their eyes met briefly, as Luna pondered which punishment would be the least offensive for her sister to bear.

Having just experienced the first two, she had no desire to impose such a disgusting task upon Celestia. Her stomach clenched at the thought of having to do it again, herself, and she definitely would not be serving her sister her own feces. But the third option was no less vile to think about. Forcing Celestia to copulate with someone randomly, a changeling even, was a grotesque thought.

And yet, a small part of Luna’s mind reasoned what could just one more notch possibly count on her sister’s bedpost. Her looseness was, as Chrysalis had put it, prodigious. While she would not by any means refer to her sister as a “slut,” Celestia was indeed quite a sexually experienced woman. By over three hundred fold, apparently. Having another one should mean nothing in the long run.

“The last one,” Luna finally decided. “We choose to add a number to our sister’s count.” Surprisingly, Celestia’s eyes hardened at the choice and she crossed her arms. She did not say anything in protest, but Luna suddenly felt anxious that she had made the wrong decision. Not that there was any good solution to their current problem, but the alicorn was confident that she had picked the path of least harm to her sister.

“Very well,” Chrysalis replied, and Luna was suddenly pushed backwards forcefully as the magical barrier reappeared between the two princesses. The coldness in Celestia’s eyes was quickly replaced by concern.

“Luna!” she called out as the younger princess fell backwards and caught herself with a hand.

“We are fine, ‘Tia,” Luna replied as she got back to her hooves. She had no other time to respond further as the pop of magical teleportation suddenly sounded throughout the cavern and a changeling drone suddenly appeared in front of Celestia.

The white alicorn was forced to her knees by an invisible force as the limber changeling approached. Already, his cock was hanging low and proud between his legs, and Celestia’s eyes widened at the state of it.

His dick was filthy. The long, black length was coated in a film of what looked like weeks worth of spent semen and sweat, and there were visible chunks of smegma hiding in the ridges of the leathery flesh. Celestia’s nose cringed as the potent smell of unwashed cock drifted over to her,

“Where do you want it?” a gruff, hissing voice asked.

Celestia gulped. “Anywhere but my mouth… please,” she begged. Anything to get the disgusting rod away from her face.

Without any defiance, the changeling obliged and silently made its way around to her rear. A strong pair of hands gripped the alicorn’s ass and she let out a yelp as she was harshly pulled backward. Her white gown was carelessly torn and flipped over her back to reveal a not-so-modest lace thong strung taught between her full cheeks. It was quickly removed however, the thin band viciously snapped as it was yanked away before being tossed to the side as the weight of his nasty, greasy penis flopped down over her butt. She quickly reached back to pull her tail out of the way so as to not get its filth in her prismatic hairs.

Those strong hands came down to pry Celestia’s cheeks apart to expose her pristine, white ponut, the round doughnut of flesh popping out from between the lumps of soft flesh enticingly. He let go of one cheek to reach down and take hold of his girth and aim it right at the center of the waiting pucker, and Celestia grunted as the wide, flat head pushed against her wrinkled rear entrance. His hand returned to the side of her ass, and she noted with distaste that it took some of the greasy dick-slime with it to smear across her white bottom. But she didn’t have long to worry about it as he speared into her with a grunt.

Strangely enough, the vile mixture on his cock made the entrance easier, and along with the looseness of her anus, the drone was able to find a quick rhythm as he began to pound the alicorn’s ass. Celestia had to let go of her tail to brace herself in the front with both hands as the thrusting increased, her entire body rocking forward with each slam of the changeling's hips against her rotund bottom.

Against her own will, Celestia found herself beginning to grow aroused by the anal attention. Her pussy moistened as her asshole was stretched, and she began to unconsciously push back against the changeling’s hips with each and every thrust. They both began panting as they lost themselves to the quick and dirty sexual pleasure, and Celestia soon forgot that she was even being watched.

Luna tried to tear her eyes away from the crass display in front of her, but found that she couldn’t. Her sister was very clearly enjoying the sodomy, whether she was first opposed to it or not. Perhaps Chrysalis was right about the older alicorn’s sexual proclivity.

Celestia could not hold back a quiet moan as the changeling slammed into her ass over and over again, and she arched her back up slightly to better feel the sensations within her. Her dress became loose around her with the violent rocking of her body, and she couldn’t help but reach up to squeeze at one of her breasts through the thin fabric. The rigid outline of her nipple pressed into her palm, betraying even more blatantly just how aroused she had become from the anal assault. She bit her lip as she threw her head back and continued to grind back into the changeling as she could feel her orgasm slowly building within her.

Then, without any warning, he hilted himself in her ass and began to pump her rectum full of his hot, thick seed. His tip flared inside of her, and she could feel her pussy clenching on nothing as cum rushed into her rear. The sensation didn’t quite bring her to orgasm, but instead left her desperate for her own release. But before she could even reach her hand down between her legs, she found herself letting out another, louder moan as he forcefully pulled himself free from the tight confines of her ass.

The alicorn’s anus clenched down on the sudden emptiness, and a off-white fluid drooled out of the gaped hole with nothing to block it. There were brown tinges mixed in with the cum, and as Celestia looked at the cock that was suddenly dangling in front of her face, she noticed with embarrassment that it was now smeared with her own shit as well as the filth from before. He reached down to grip the filthy member with his hand and point it at her, bringing it even closer to her disgusted face.

The smell nearly made her gag, and she leaned as far away from the disgusting dick as she could. “Clean it,” the changeling’s hiss spoke again. “With your warm, royal mouth.”

Celestia shook her head. There was no way that she was putting that thing anywhere near her mouth. Suddenly, Chrysalis’s voice returned. “If you don’t do it, Luna will have to,” she taunted in a sing-song voice.

Reluctantly, Celestia looked back at the dick in front of her as the drone shook it crassly. A war waged in her mind as she willed herself to try and open her mouth, but she just couldn’t do it. The smell of it alone was stirring her stomach in the worst way imaginable, and she couldn’t even bring herself to let herself taste it.

“I… I can’t,” she whispered hoarsely. She looked over to Luna with remorse on her face and repeated, “I’m sorry I just can’t do it.”

A look of utter betrayal dawned on her sister’s face and it pained Celestia’s heart. But before she could even as much as reconsider her choice, the changeling let go of his dick and pressed his dirty hand into her shoulder to roughly push her aside as the magical barrier fell and he silently approached Luna.

“No! Wait!” the younger alicorn called out as she was pushed down onto the floor before the changeling. The smell of its dirty dick graced her nose just then and she was once again subjected to the foul scent of shit. This time, it was fresh, however, and carried a sharper scent. It was also mixed with the sexual slime of semen and smegma, two things that Luna had no desire to put anywhere near her face.

But she had no choice.

Her jaw was magically pried open and the filthy cock was unceremoniously shoved into Luna’s mouth. The disgusting, vile tastes of her sister’s shit and the sour taste of horse smegma scraped against her tongue as the phallus was lodged nearly all the way back towards her throat. In some way, Luna was glad that she had been forced to consume the scat in the previous challenge, as it served as some sort of sick warm-up to the torture she was now forced to endure. It was perhaps the only thing that kept her from vomiting as the drone forcefully cleaned his cock with her mouth.

He thrust into her a few short times, making sure to stick his dick into each of her cheeks and scrap as much of the foul gunk off of his leathery length as he could. When he pulled it out again after a few moments, it still looked filthy, but was lacking the larger globs of shit and cheese that were previously there, and was instead coated with an additional sheen of Luna’s saliva as well.

With her mouth empty, Luna took the opportunity to spit out the gross chunks of filth that had been left behind onto the floor. She desperately scraped her tongue against her teeth to get as much as she could out, nearly gagging as the effort spread the bitterly sour taste even further towards the back of her throat. With a heaving retch, she managed to get the last of it out, but the persistent taste lingered no matter how much she spat out onto the floor.

As Luna tried to evict the foul flavors from her mouth, the changeling crossed back over to the other side of the cavern to where Celestia was still on the ground. She looked up at him wearily as he approached and knelt down behind her. He lifted her ass back up towards him with little resistance, and she let out a soft moan as he pried her sore asshole open with his fingers.

More nasty cum drooled out of her wrecked hole, dribbling down over her slickened pussy. The changeling reached down to grab his dick and drag it through the mess, re-coating it in another layer of filth.

“Push,” he commanded roughly, and when Celestia hesitated to comply for the sake of her sister, he reached under her to push on her abdomen. The action sullied the white fabric of the dress on her stomach and forced her bowels to contract and push out the remainder of changeling spunk onto his waiting rod. A grotesque chunk of fecal sludge also squeezed its way out of her anus, and the drone wasted no time in catching the lump of soft shit in his palm to generously smear all over his turgid member. He jerked himself off slowly, making sure that her shit was fully spread all over his dark length before he stood back up and walked over to the other woman.

Luna’s face went green as the freshly coated cock was pointed back at her face. The potent stink of Celestia’s shit burned her nostrils with every breath. While the phallus had anal residue previously, it was not to this extreme. Practically the entire length of the changeling’s dick was coated with a thick, smeared layer of crap.

She figured she didn’t really have a choice in the matter, but that didn’t mean she was going to do it willingly. “You can’t possibly be serious,” she muttered as the changeling shook the rod impatiently. He ignored her protest and instead mimed thrusting forward, the wide head of his turgid cock smearing a distasteful paste of shit and pre onto her sealed lips. She groaned in disgust, appalled at having to not only clean the offending member, but having to do it twice. It was degrading, and as he pushed against her mouth again, smudging even more of the vile filth onto her face, she realized that she didn’t really have a choice in the matter.

With dismay, the alicorn resigned to just letting it happen. Looking up at him with a face of pure disdain, she hung her mouth open and lolled out her tongue to let him in. He wasted no time in angling his penis towards her open maw and guiding it inside.

The taste that befouled her tongue was just as bitter as ever, and Luna gagged as she dutifully tried to slurp all of it off of the pulsating flesh. He let out a sigh as he pushed deeper into her mouth, encouraging the princess to take in even more of it, gradually going deeper and deeper until it began to slip into her throat. Luna gagged - not from the taste, but from the sheer volume of dick in her mouth. She was confident that she couldn’t possibly fit any more of it in there. Brown drool dribbled out of the corners of her mouth and down her chin as the thick cockmeat took up all of the room in her mouth. Then, at an agonizingly slow pace, the changeling began to pull it back out.

Luna kept her lips locked around the phallus as it slid out of her mouth, making sure to scrape all of the scat off of it as it withdrew. Her lips smeared brown with the creamy paste as it was trapped in her mouth. The flared head of his horsecock popped out of her mouth with a wet pop, and she grimaced as he dragged it along the side of her face to try and get the residual shitty slime off.

Satisfied that his cock was clean enough, he took a step back as he began to vigorously stroke his still-throbbing prick rapidly. Knowing what was about to come, Luna squeezed her eyes shut and turned away just a thick rope of cum shot out of his flare right at her.

The kneeling woman let out a wince as the warm, viscous fluid draped against her face and tangled in her hair. Stream after stream of the musky fluid ejected from the twitching cock as he grunted in time with the pulsing of his second orgasm. But there was nothing she could do but sit there and take it silently. Any rebuttal on her part would no doubt be punished, and she feared what Chrysalis may come up with next.

She didn’t even notice the changeling leave and her sister came to her side. The other alicorn simply stood there silently as Luna spat out as much of her shit as she could from her mouth, the brown muck oozing from her mouth in a thick paste. She wiped at her face with a few dainty fingers, wringing excess cum from her brow so as to not get it in her eye.

“Luna,” Celestia said quietly as she watched her sister try to clean herself up to no avail. “Are you alright?”

“We will be fine,” Luna whispered with disdain as she glared up at her sister, streaks of semen dripping down the side of her face. “No thanks to you.”

Celestia frowned. “I- I’m sorry. I just couldn’t do it. I… I tried but it was too much.”

The younger alicorn’s glare intensified as she rose to her hooves. “So we were left with the burden in your stead,” she said accusingly, pointing a finger at the other alicorn.

Her sister’s attitude began to get on Celestia’s nerves. “Well, I mean you did just have that brute pleasure himself with my body! There was only so much I could take!”

Luna laughed sarcastically. “Oh, please, sister,” she said with a sneer. “You were practically drooling with bliss as he took you. It’s not like we couldn’t see your tongue dangling from your lips, or hear your lascivious moans as he claimed you!” She waved a hand at the collar of her sister’s dress, which had been stretched down to reveal most of her left breast. “You ruined your own blouse to provide easier access for you to grope your own bosom, for star’s sake!”

Celestia huffed as she took a step back and crossed her arms over her partially-exposed bust. “That’s cruel of you, Luna,” she said coldly. “I would have thought you would be more sympathetic.”

“Tsk tsk… now, now, girls,” Chrysalis’s voice called out before Luna could reply. “Cut the bickering. There is yet another challenge waiting for you ahead! Let’s not get too… distracted.” Then, she chucked before adding, “By the way, Princess Luna… brown is a lovely shade of lipstick for you.” Luna’s brown-tinted lips formed an even angrier frown as she bashfully reached up to try and clean off the leftover waste with her fingers as she glared up at her sister..

The silent standoff between the two sisters continued for another, agonizing moment before Celestia turned away and began to walk towards the next room. Luna only felt a tinge of remorse as she watched her sister limp slightly with her tail to the side, no doubt sore from the anal pounding that had just been forced upon her. Maybe Celestia was right, maybe Luna should be a bit more sympathetic.

“Tia, I-” she began to apologize, but she was cut off by a cold glare from her sister.

“I don’t want to hear it, Luna,” Celestia said tersely. “Let’s just move on.”

With nothing left to be said, Luna followed behind her sister and the two alicorns stepped into the next chamber. The rock face reassembled itself behind them, trapping them in whatever vile challenge that the changeling queen had planned for them next.
