Chapter 1

Version: 1

Terrance finished his glass of water with a pleased sigh. It might have been a boring drink to most, but he was happy with it. After all, he'd yet to find a coffee or tea he liked and it was far too early for any kind of alcohol. The only thing that mattered was his quiet morning. Yes, it was times like these, as he eyed his simple dining room, that everything simply felt normal. Where someone as uninteresting as himself could just relax and enjoy the lethargic atmosphere. Bask in the peace. Find comfort in the completely mundane.

Then everything vibrated for a second. Then again. Then again.

The floor. The walls. The table. Even his chair. The whole house shook over and over. Like a series of distant explosions.

Finally everything went still. And after a moment there was a knock on his door.

Well, it might have been more accurate to call them loud crashes. The sound was closer to that of a battering ram. It was a miracle the wood barrier wasn't sent flying off its hinges. Anyone else would have thought they were under siege. But Terrance only sighed with resignation. It seemed his morning was over. It was time to start the day. So the man grunted as he stood to go answer it.

Outside there wasn't a typical yard. He had no grass, or hedge, or trees. Not even a fence or a mailbox. The only thing beyond his door was a spotty dark brown plain. The ground looked sort of like stained wood. Which ended in an abrupt drop some dozen feet away.

And past that was the towering form of a white unicorn pony decorated in golden armor. So huge he literally cast a shadow over Terrance, his not-yard, and his home.

Because Terrance was just a centimeter tall and his entire house took up only a small desk.

"Good morning," the stallion greeted politely.

"Morning," the man called back.

A month ago he would have been shaking under the gaze of the massive equine, barely able to even speak. But humans were capable of getting used to anything and now being around ponies as large as skyscrapers was simply part of life. Though he'd be lying if he said there wasn't at least an ember of lingering fear. Any one of them could end his tiny existence with but a twist of a hoof. So he'd learned proper manners very quickly.

"What's the schedule for today?" Terrance asked as he trudged towards the edge of the desk.

The guard's horn glowed as he levitated a clipboard up to his muzzle. Like he needed to check. It was pretty much the same every day. "First you have a physical with Doctor Curious, then you have cardio training with Coach Warmup, followed by a shower and lunchtime. After that Celestia wishes for you to observe Day Court for at least an hour. Then you're free until your evening meeting with the Princess."

"Sounds right," the man commented with a shrug as he reached the end of the table. The stallion grunted his approval and returned the clipboard to a hook on the side of his armor. Then he presented Terrance with a plastic box.

It was the little human's personal transport pod.

The centerpiece of the carrier was a padded chair complete with a full-body seatbelt for safety. Flanking that were two storage chests, also fused to the floor to prevent sliding. Other than a pillar in each corner that connected the base to the domed ceiling, the walls were open so Terrance could enjoy the scenery while he was traveling. On the roof was a mouth-handle for when non-unicorns had to carry his pod.

The man casually stepped into his transport and buckled himself in with practiced ease. Once he was secure he called out to his escort. "I'm good!"

The stallion lowered the carrier until it hovered at about chest height before he turned for the door and took Terrance away.

Unicorns were definitely the best. Right now his experience was smooth as butter. Not that the little man blamed earth ponies or pegasi. They just couldn't help the bouncing and swinging. Unfortunately Celestia couldn't always assign him a unicorn. The few times he'd had a non-unicorn chaperon left him feeling like he was on an amusement park ride. His guts would lurch with every sway and his teeth would clack with every thunderous step the giant took. Those trips threatened to make him sick. So today was shaping up to be a good day.

While they made their way down a boring hall, the terrain too familiar to offer any meaningful stimulation, the rhythmic booms of his current escort's hooves lolled Terrance into a trance. He was about ready to fall asleep when a sudden sound not unlike a balloon deflating snapped him awake. He blinked away his confusion for a moment as his mind restarted. Then he groaned, having realized what it was.

His guard had farted.

Two months in the pony world had already dragged him through plenty of culture shock. Easily the biggest example was how casual ponies were about breaking wind. And how frequent it was. The first week it was gross and awkward, though he'd also been pretty distracted by terror at the time. The two weeks after that he'd relaxed enough to simply be confused by the constant and very public farting. Which was followed by a period of amusement. These days he found their indifference to letting it rip whenever and wherever mostly annoying.

While Terrance never had found the courage to actually ask, he was fairly certain he'd figured out why ponies were so shameless about it.

It was because they had to be. Ponies were just gassy creatures.

Once the man had settled in after his accidental arrival in the magical land of mythical creatures, he'd had a lot of time to meditate. Which let him remember old biology classes about big herbivores like cows and horses. While most of the fine details were long gone by now, he did recall that digesting grass was hard to do and produced a ton of gas as a byproduct.

Which meant ponies simply couldn't afford to shame each other for farting in public. They risked hurting themselves if they tried to hold it in for any amount of time and it would have created social problems if they were always chiding each other for letting it rip. So their biology forced their culture to ignore it. Nopony giggled, judged, or so much as commented when one of them passed wind. For ponies it was completely acceptable and natural to fart, even loudly, in public.

But it was hard for Terrance to get used to. Maybe impossible. Because he was so much smaller than ponykind even their most miniature farts often sounded like a foghorn. Which was very attention grabbing. Mercifully he rarely smelled anything. So, between the embarrassment of even trying to bring up the subject and his fear of offending somepony, the man chose to endure in silence.

Like now, all he did was roll his eyes at the stallion's casual release and hope the rest of his day passed with less awkwardness.

"How are you today, Lord Terrance?" Celestia teased from her resting place on a cushion.

"I just got here and we're already doing this?" the man grumbled back.

The Princess snickered into the crook of her hoof. "Sorry Terry," she sassed playfully while levitating his transport pod away.

He growled even though he wasn't really that mad. But he still had to make a show of it. So he crossed his arms, aggressively sat down on his pillow, and looked away without saying anything.

"Oh Terrance," Celestia cooed. "I just can't help it. After a long day trapped in my official princess role, I simply love our casual chats. I'm sorry I get caught up in the moment and make you all flustered. Please forgive me."

The man sighed dramatically and put his hands up in surrender. "Fine fine. Just stop mentioning the 'Lord' thing. I still don't like it. I don't deserve it."

Celestia pouted. "Only you would complain about getting a noble title. Do you have any idea what most ponies would do for that?"

"Well, I'm not a pony," Terrance stated bluntly.

The mare nodded somberly. "Indeed you are not. But it was the easiest legal way to keep you here in the castle."

The man sagged, tempted to simply fall back into the landscape that was his pillow. "Stupid bureaucracy," he mumbled. "Will I always have to watch Day Court and attend those advisor meetings or will that go away at some point? It's not like I really contribute. I don't know anything about politics or Equestrian law."

Celestia straightened and her voice took on a formal edge. "I believe I already explained this, but to retain your title -- and continue to get free support from the royal treasury -- there is a minimum... attempt that must be maintained."

"And 'ambassador' wouldn't have worked?" Terrance offered half-heartedly.

The Princess shook her head seriously. "Ambassadors don't get assistance from the treasury unless there is an emergency. Their home country is supposed to pay for them, not the country they're sent to. Plus, the duty of an ambassador is to serve as a bridge for diplomacy. But we can't reach your people. There are no issues to negotiate. No conflicts to work through. Nothing. And it's not like your kind sent you here to represent them either. Your arrival was entirely unpredictable and an accident."

"Yeah yeah. So you had to exploit technical legal stuff to keep me around," Terrance cut her off with a huff, not wishing to hear yet again how the jealous nobles could try to sabotage his life. But the man soon tiredly gazed up at the living mountain that was Celestia. His friend. "Thanks," he sighed.

The white mare smiled gently back. "You're welcome."

The two of them shared a peaceful moment.

"Tea?" the Princess offered.

"Just water please," Terrance countered smoothly.

Celestia scoffed. "I'll get you to drink with me some day," she chuckled even as her horn glowed and their drinks began levitating towards them.

"I don't know how your mouth survives something that bitter." The man gagged at the memory.

She hummed as their beverages arrived. "It's not bitter. It's refined."

"Must be your pony taste buds. They don't work right," Terrance quipped playfully.

Celestia snorted while trying to enjoy her tea. "Perhaps it is your human taste buds that are wrong."

They chuckled.

After a minute they finished their respective drinks and it was time to get down to business.

The alicorn set her teacup aside with a small clack of porcelain and cleared her throat. "Terrance, today I want to talk about something I suspect will make you uncomfortable. Is that okay?"

The man blinked. "Uh, sure? Whatcha got for me?" he asked while straightening his posture and holding out his glass so she could return it to the desk.

"I wish to talk about sex."

Terrance choked on his own tongue and made various confused noises that weren't even close to real words.

The Princess took his shock in stride and merely nodded. "We've talked about your technology, science, culture, and history. But we've never touched that most sensitive part of human nature: intimacy. How do humans copulate? How do they like it?"

The man stared in awkward silence. Though he was kind of out of it so how much time actually passed got a bit vague, he did eventually find his voice. "Why?" It might not have been the most elegantly worded question, but Celestia seemed to know what he meant.

"Sex is an act of trust and love," the white mare explained sagely. "And on a larger scale it can serve as a strong hint to the nature of a species."

Terrance could only gape stupidly. Said by anyone else he would have sworn they were full of crap and just making excuses to talk dirty. Except this was Celestia. Maybe she really was that curious about his kind. Maybe she just knew something about life he didn't understand. There were a lot of sentient races on Equuis she had to deal with on a regular basis after all. Who knew what secrets and trends she had stumbled upon over the centuries.

Or she simply wanted to see him flounder in embarrassment. He knew she liked a good joke, but this went kind of far to be only a prank. So he mustered his will to give her a meaningful response.

"Right. So," he droned. "Sex is... complicated."

Celestia snickered once. "Of course. Relationships are a tangled mess for ponies as well."

Terrance scratched his head. He wasn't honestly sure how to answer her question. He knew what a few other people liked (for obvious reasons). But mankind in general? He knew there had been surveys, but he'd never looked at the results. He'd never cared. So Terrance struggled to craft a useful explanation. "Most humans... are kind of boring. They rely only on different... positions."

The alicorn quirked a brow. "Positions?"

"Yeah," he reiterated with growing confidence. "Sex isn't just about getting the stick in the hole. Humans like to... do it from different angles."

"Ah," she hummed in understanding. "Describe some for me."

Terrance was fully blushing now as he began listing and explaining what he thought might be the most common ones. Missionary, cowgirl, reverse cowgirl, and doggy style.

"Interesting," Celestia commented to herself. "What about games? Do humans like to play in the bedroom?"

"Do you mean fetishes?" he asked timidly. After her quick nod he suddenly had to wipe some sweat from his brow. Terrance did not expect to be talking sex with the goddess of the sun today. He had to swallow back his nervousness so that he could sound smart and professional. "Humans have countless kinks," he asserted vaguely.

The mare smirked. "Really now? Like what? What is typical?"

Terrance cringed. There were certainly rare and bizarre fetishes out there, but only one that jumped to mind as common. And he wasn't actually sure that it was. "Well... there is a family of kinks called BDSM..." he mumbled.

"And what does that stand for?" Celestia prodded knowingly.

"I'm not exactly sure," he admitted while rubbing his temple. "I believe it spells Bondage, Domination, Sadism, and Masochism."

The mare stared at him, speechless for a moment. Long enough the man actually started to worry. Then she whispered. "I guess we're not that different after all."

"What?" he honked.

"I believe the last update I received on the matter said that about half of ponies have one or more of those very fetishes," Celestia explained with a chuckle and a shake of her head.

"You get reports on this kind of thing?"

"I get reports on everything," she sighed with exasperation.

"Why?" Terrance stuttered.

Celestia blinked and raised a brow. "Because I'm the Princess."

"No," the man clarified slowly. "I meant, why do half of ponies want... that? Your kind seem so... friendly? Isn't BDSM kind of... mean?"

The alicorn made a silent "oh" as she perked up. Then she giggled. "My dear Terrance, despite how cultured we may appear, ponies are still animals at the end of the day. And old instincts die hard. It is simply a lingering ember from our ancestors."

The man couldn't help his bafflement. "How?"

Celestia smiled, as usual getting excited when the opportunity to share some great wisdom appeared. "Prior to the rise of civilization, herds of wild ponies roamed the wilderness, struggling for survival. In those harsh times, before recorded history, the only thing that mattered was strength. Whether it was fighting predators or driving off competitors, the best mates had to prove themselves. Males and females even developed a complex dance of sorts. Where they would push and shove each other as a test. Neither wanted their partner to think of them as weak and therefor undesirable. So mates would -- oh, what's the word? Wrestle."

Terrance nodded along slowly. Her story made sense so far. Except for the final connection, which was still kind of hanging. "So ponies instinctively... challenge each other?"

The Princess beamed. "Exactly! It's in our blood. The desire to be worthy of our partner. In modern times however, those ancient drives manifest as games of dominance. Particularly for sex."

The man was left shocked. He had no idea how to respond. So much for cute and innocent. "That's weird."

Celestia smirked. "But you said your kind have the same fetishes."

"Well... yeah," he admitted weakly. "But not to that extent. Not... half."

"Really now?" she challenged. "How common is BDSM among humans then?"

"Um," he droned awkwardly for a moment until he eventually had to come clean. "I don't know."

The mare relented at his answer, choosing to shift the focus of the topic. "I see. Based on your reaction, I take it you are not a fan of Domination then?"

His first impulse was to reply with no, yet he hesitated. He could have sworn Celestia sounded just a little bit disappointed. And he could actually imagine getting into it. Maybe. "I'm not sure."

The Princess raised a brow. "Oh?"

Terrance regained some of his nerve as he justified himself. "Well, it's a mark of pride for a man to make sure his woman is satisfied first. To please her. One way to do that, I guess, is to take charge. To hold her down and give her everything."

Celestia seemed to relax at that, sinking into her cushion. Though she did have a question. "Only the male is supposed to do this?"

He shrugged noncommittally.

"Would it bother you if the female took charge? To please herself?" she pressed.

Another shrug. "I guess that'd be fine with me. As long as we both... finished," Terrance said, his face suddenly heating up as he remembered what he was talking about and with who.

Celestia grinned. "Maybe there is hope for you yet then."

Now it was his turn to blink in confusion. "What do you mean by that?"

The mare leaned forward, until her huge muzzle was hanging over him, then she whispered like she was revealing some dark secret. "Because I bet there are plenty of mares who'd love to dominate you."

The man actually jumped to his feet and stumbled back at the sheer brashness of Celestia's suggestion. Though he quickly fell on his butt again after only a step or two. The vast pillow-landscape was kind of hard to walk on even while not in the middle of an emotional earthquake.

The alicorn retreated with a hearty laugh at his reaction. "Have you never even considered it before?"

"C-Celestia!" he barked. But after taking a moment to recompose himself he continued with a more neutral tone. "No, I haven't. I'm an alien from another dimension the size of a bug. Why would any mare want me?"

Celestia's expression fell and her tone became sympathetic. "Actually, there are many who would consider you quite attractive."

Terrance floundered for a few seconds as he tried to respond to that claim. "What?"

"It's called 'Domination', Terrance," she began patiently. "While most ponies are instinctively drawn to a mate they see as an equal, many are drawn to a partner they see as... less."

"So... because I'm worthless I'm desirable?" he asked a bit sharply.

"That's not what I meant," the Princess apologized with pinned ears. "It's that you are physically smaller."

"Being small is attractive?"

"In a manner of speaking? Yes," Celestia concluded with a definitive nod.

Terrance shook his head. "That's crazy," he muttered.

Celestia snorted with amusement. "First a Lord, now the most eligible bachelor in the kingdom. You're doing quite well for yourself after only two months."

The man grumbled and waved a dismissive hand. "Please stop teasing. It's weird. All of this is weird."

"Though Domination isn't really a fetish," the mare commented mostly to herself. "You'll probably have to be prepared for something more... specific."

Terrance felt a tingle of nervousness run through him. "What do you mean?"

Celestia eyed him for a moment as the tension grew thicker. She licked her lips. "Well, Domination always involves some kind of wrestling. In the best case for you it'd just be aggressive snuggling."

"Aggressive snuggling?" the man repeated dubiously.

The Princess rubbed her chin as she thought allowed. "Any mare interested in you is definitely going to have a power fantasy. Holding you down with a hoof or laying on top of you are obvious ways to express it."

Terrance winced. "That sounds dangerous. You ponies are huge. You'd crush me like that."

"Not if we did it on a soft enough pillow," Celestia countered, bluntly gesturing to the plush cushion he was currently sitting on.

The man wordlessly gave the spot next to him a pat. Yup, as usual, it was very soft. But soft enough to keep him safe while a hoof larger than a basketball court came down on him? He shivered. "I'm not sure about that."

"And it's not like she'll want to hurt you," Celestia added. "It's a game."

"A scary game," he said dismissively.

Celestia offered a reassuring smile. "Only let a mare you trust do it then."

The man's face scrunched as Terrance considered that one. "Who could I possibly trust with pretending to... crush me?"

"Who indeed," the Princess echoed coolly. "But I doubt that's the only thing you'd have to endure."

"Huh," the man honked anxiously. "What else could somepony want to do with me?"

There was an eerie pause as the mare wavered. As though suddenly second-guessing whether to share her thoughts. She even looked down and worked her lips for a moment. Which made Terrance more worried by the second. Celestia had been cheeky pretty much this whole time. Riding through the strange turns and awkwardness of their conversation with ease. What could make even her hesitate?

But she eventually found her voice. "Are humans familiar with... farting... as a form of sexual stimulation?"

Terrance gawked. His mind completely stopped. That was the last phrase he ever expected to hear in Celestia's voice. And despite how long she had taken to say it, he must have outdone her when forming a response. "That... is an extremely rare fetish," he mumbled.

Celestia's ears pinned and even she started to blush. "I see. Well, about one in five ponies have it."

It was one mental bomb after another. The man simply couldn't handle it, yet also couldn't stop himself from digging further. "Why?"

"Because it is the greatest act of humiliation. Of proving one's physical superiority. To immobilize your partner with your ass and to gas them is the pinnacle of dominance. Of control," she explained seriously.

Was that the first time Terrance heard Celestia swear? No, that didn't matter. "That's... what a fifth of ponies -- mares -- would want... with me?" he rambled.

"To sit on you," the alicorn summarized darkly, "and fart. To make themselves feel powerful."

Everything Celestia said knocked his mind for a loop. He was lost. Stranded. Drowning in a confused spiral of nonsensical thoughts. Terrance was literally dizzy and had to hold his head.

"Celestia. Can we talk about... something else? Please?"

The snow white mare whined sympathetically. "Sorry. That topic got a little too personal. Here, let me get you some more water."

How she was able to precisely conjure water into his tiny glass he had no idea, but right now he did not want to think about anything. Before he knew it he was gulping down the refreshing drink and gasping for breath after. He then declined a refill and instead returned his glass to Celestia. Finally, Terrance did what he'd been tempted to do several times since this meeting started: he fell back, spread his limbs as far as he could, and simply sank into the fluffy pillow.

Celestia chuckled. "You look silly."

He retorted by closing his eyes and snorting. "Well it feels good. You should try it sometime."

"I think I will," she replied before there came a small shuffling sound followed by a sudden ballooning of the landscape beneath him.

Terrance jerked upward only to find the end of a huge white muzzle sitting on his pillow. Tilting to the side so he could see around it, it soon became obvious what had happened. Celestia was too big to lay down on her own pillow unless she curled up. So the massive mare just stretched her neck to drop her chin on the end of his.

Terrance grunted with exasperation. "Do you mind?"

She grinned. "Not at all. And you were right, this is quite comfortable."

It wasn't like he needed the whole thing, but still. It was his territory. "Ponies," he grumbled.

Celestia stuck out her tongue. "Humans."

They stayed like that for a minute. Both of them sprawled without any regard for dignity. The towering equine's every breath sending a gust of air over the little man below her nose. It was nice. Calming.

"Better?" Celestia prompted after awhile.

"Yeah, I guess," Terrance sighed. "How did we get to that?"

"To what?"

He swallowed. "To what would happen if I tried dating. What kind of... fetish... I'd have to be ready for."

"I wanted to know about human sex games," she stated simply. "Does the thought really scare you that much?" she urged quietly.

"Being a toy for a giantess? A little. Being held down? Yeah. Being... farted on? That sounds like torture."

Celestia's lips tightened. "Would it really be that bad? You'd get to play with her ass all the time."

"True," Terrance mumbled slowly. "But... farting... is gross."

"I see."

The man sat up, but his entire view was just the end of Celestia's muzzle with some of her rainbow mane rising in the distance. "You sound disappointed."

The mare's breathing hitched for a second. Followed by a single big inhale before her mouth opened a crack and she sighed. Right through him, ruffling his shirt and hair. Then, while Terrance was blinking his suddenly dry eyes, Celestia sat up too. She tucked her legs underneath herself and adopted a formal pose while she waited for his attention. Only then did she launch into some kind of official speech.

"Terrance, I would like to make you an offer. An alternative to being a Lord. The position hasn't been occupied in over a century so even most of the nobles have forgotten it exists, yet it is a legitimate documented legal station. Complete with unique perks and... a more specialized obligation."

Terrance scratched his head, unsure where this was coming from. Or going for that matter. Was she ignoring his question? While he was a bit annoyed by that he was also utterly captured by his own curiosity. Why had she not brought this up any other time he'd complained? Why now? "So I wouldn't have to observe Day Court or go to advisor meetings?"

She shook her head seriously. "Correct. This position does not require you to engage with political matters of any kind. Though you will be able to should you change your mind. In fact, from a certain perspective, you might have more sway in the Royal Court than any noble."

Terrance wasn't excited by power or influence. "Okay? But what is the job?"

Once more the alicorn hesitated. She closed her eyes. Swallowed. Took a breath. Then opened her eyes again and spoke as neutrally as he'd ever heard her. "The Royal Concubine."

Silence. Long and cold. The kind that makes the skin itchy and the air seem thick.

"Celestia," Terrance began softly. "Is this your way of saying that... you're... interested in me?"

She blushed. "Yes. I like you. I like spending time with you. I like talking to you. We obviously have good chemistry and I don't care that you're not a pony." It seemed like she had a few other points ready to rattle off, but stopped herself out of building embarrassment.

"Then why not marriage?" the man pitched absentmindedly, still not fully processing what was happening.

Her ears pinned. "I can't. As a Princess of Equestria, I cannot legally marry a non-royal. So concubine is the most... the most I can ask," she whispered.

"Whoa," was all Terrance could manage as he began rubbing his head.

"I see you are not immediately against the idea," Celestia noted with a fragile and obviously nervous half-smile.

The man's eyes snapped back into focus. "No... I mean -- I like you too. You're basically my best friend. I think I'll -- God, I sound stupid right now don't I? I'm sorry, I guess I'm just overwhelmed," he sighed.

The mare's smile grew firmer. "I understand."

"But you could've picked a better time, Princess," Terrance sassed, trying to regain some of his confidence. "Why would you propose after talking about all that dark kink stuff?"

Celestia's smile vanished. "Because I needed to know if you'd be open to my fetish."

The man's shoulders started to feel heavy. "Uh, Celestia? Does that mean you...?"

The alicorn's rigid voice and posture returned as she dropped back into official explanation mode. "The duty of the Royal Concubine is to aid the royal family in de-stressing and to physically please them. In other words, they are to fulfill whatever sexual desire is asked of them by the princesses of Equestria. In exchange they are guaranteed housing in the castle, a substantial income, the second highest security clearance an officer in the military can earn, and are privileged to always have the royal ear without the need to navigate any of the obstacles of bureaucracy."

Celestia glanced up as she took a breath before meeting eyes with Terrance again and adopting a quieter tone. "Should you accept, be warned that Luna can also demand your services and you may not refuse without surrendering your position. Or facing... other consequences."

"Okay..." the man nodded carefully. "But about the fetish thing..." he nudged.

She licked her lips and squirmed in place. "Look, there is no easy way to say this, considering what you've told me. Our relationship is never going to be the same regardless. So I'm just going to be blunt."

A moment passed.

"I want to fart on you."

In an instant a storm of emotions rushed through Terrance. Confusion. Fear. Betrayal. But there were some he hadn't expected. Curiosity. Excitement? Lust? What was happening to him? How should he respond? Make demands? Accuse? Question? After everything she'd done for him and all the good memories? After how far she'd gone to make him comfortable and to ensure his safety in a world far too big for him? After becoming his light in the darkness when he was surrounded by strange creatures?

Ultimately, it was the feeling of betrayal that won. "Why?" Terrance asked with a tremble while instinctively scooting away from her.

The towering mare winced like she had been slapped. "I have a power fantasy, Terrance. You know I didn't become Princess Celestia by smiling all the time. I fought to build this country. I had to overthrow tyrants, seal away ancient evils, and duel with mad ponies to shape this land. Yet those days of struggle are over. Along with the thrills," she sighed at the memories. "These days my royal duties involve... talking," Celestia remarked bitterly and stuck out her tongue. Then eyed him with what could only be described as hunger. "But you," she breathed huskily. "The mere sight of you ignites a fire in me."

Terrance felt a bead of sweat dribble down his forehead under the intensity of the giant mare's gaze. "I do?"

"Yes. You're small and delicate. Very nearly helpless. Just looking at you fills me with thoughts of how easily I could just... hold you down. And do anything," the enormous alicorn described dreamily. Though after a moment she looked away with rosy cheeks. "I'm a winner, Terrance. I want to feel strong. I want to feel powerful. I can't do that in a courtroom. Sure I always 'win', but verbal victories are boring. And I can't just seize anypony who annoys me and strangle them." The mare blinked thoughtfully at that for a second. "Well... I could. But it would cause a lot of problems."

Terrance started to feel a bit bad for Celestia. However, he was his own person with his own concerns. "Okay, so I get why you want to... hold me down," he shuddered. "But why fart?"

Her eyes peered into his with certainty. "Because every release is another victory."

"Would that be enough for you?" Terrance protested. "I can't even fight back. Without a challenge the whole thing seems kind of hollow."

Celestia chuckled somberly. "Great battles are extremely rare these days. I'm ready to take whatever excitement I can get. And I know playing with you would be fun."

"Playing?"

"Yeah. I mean, it's obvious what our go-to game would be," she grinned suggestively. "First, you'd pretend to be the fleeing villain. I'd chase you down and pin you beneath one of my hooves. You'd struggle for awhile, maybe I'd even let you go a few times. Then we'd banter a little and I'd taunt you with escape. Finally, once you were good and exhausted, I'd crush you with my ass and gas you into unconsciousness," she finished with a lustful moan. But then she noticed the very unexcited expression Terrance wore. "Then I'd carefully tuck you into bed and thank you for the wonderful night," she added bashfully.

"Good to know you've thought this through," the man commented slowly. "But... I'm..." his voice petered out as he pulled his knees to his chest fearfully. "I don't... want that..."

Celestia leaned forward, ears pinned and tone subdued. "How about this. We try one session. Just one. If you really hate it, that's it. No more. I'll never bring this up again. But if you like it, or at least don't mind, you become my Royal Concubine."

Under normal circumstances Terrance might have been up for some experimentation, but getting farted on by an enormous pony was beyond his comfort zone. "Or... we could not do that and pretend this conversation never happened."

The alicorn's eyelids drooped into something that wasn't exactly a glare. There was no anger behind it at least, but there was something unhappy. "You're not even going to give this a chance?"

"I don't want to be farted on," he growled. How much clearer could he be?

Celestia's lips tensed. "I see." She straightened. "Then... we'll have to see each other a lot less from now on," she remarked coldly. "This might even have to be our last one-on-one meeting."

Instantly those feelings of betrayal and anger boiled. "Y-you're trying to blackmail me into this?!"

The Princess looked away and swallowed. "That was not my intention." She sighed before facing him once more, expression filled with regret. "I'm going to be completely honest with you Terrance. You make me hot. Whenever I'm around you I'm filled with these fantasies," Celestia explained huskily. "I... need those feelings to go away and there are only two ways to do that. Either I satisfy them with your help... or I get away from the source."

The man wilted, unsure there even was a good way to respond to that confession.

She cast her gaze down onto the floor as guilt saturated her voice. "I'm sorry Terrance. I'm sorry I'm not pure and perfect. I'm sorry I have these feelings. Sorry I have a fetish that scares and disgusts you. And I'm so sorry I have to give you this ultimatum, but I simply can't stand this any longer. I want to be your friend. I want to talk about nonsense with you. I want to spend time with you. I want to waste time with you. But... you make me so horny," she quivered and moaned. Though Celestia quickly shook it off so she could finish what she had to say.

"If you really can't do it, I completely understand. But we'll have to go our separate ways. I promise to keep you safe here in the castle as usual, but we'll have to stay away from each other. Because I just... can't," she huffed. "But if you're truly determined to be with me, then I'm afraid you're going to have to do it as my concubine. I'll need you to deal with this... craving. You'll have to endure... my gas," she panted.

Terrance hissed through grit teeth. "That's not fair," he whined.

"I know," Celestia nodded solemnly. Then she licked her dry lips and continued. "Where we go from here is your choice. I will not force this on you. Fart play is... not for everyone."

The man cradled his head in his hands. He actually felt like crying for the first time since... coming to Equestria. "I... I don't... I don't know what to do," he admitted shamefully.

A glass of water levitated into his lap. He blinked at it mindlessly for a few seconds before gulping it down. Then Terrance looked up at the mare who was doing this to him. Why did it make his heart ache that she looked hurt too?

"You could give it a chance," she offered oh-so gently.

He stared thoughtfully back at her. As much as he didn't want to admit it, she was right. And those feelings of curiosity and lust did begin to bubble anew. A little. Enough for him to ask a question at least. "How much?"

Celestia blinked and tilted her head, perplexed by his question and the possible implications. "How much is the pay?"

"No," Terrance mumbled. "How much-" he had to stop to take a breath. "How much would you need... to be satisfied? How much would you need... to use me?"

The mare made a silent "oh" of understanding followed by a deep cringe. She brought a hoof to her chin as she tried to measure how ravenous her lust was. "I don't know," Celestia soon whispered allowed. "But it would likely be... often..." she confessed hesitantly. "Twice a week at least."

Terrance didn't respond for a minute or two. He was lost. Weighing his options and not finding an obviously good answer. Give up his friend or become her fart slave? He didn't want either. It was gross. He growled in frustration.

"You don't have to make the decision now," Celestia cut into his mental breakdown. "You can take a couple of days to yourself, sort out your thoughts. I know... it's not an easy choice," she acknowledged carefully. "I'm sorry."

Her attempts to soothe the chaotic mess that was his mind immediately sent the man back into his memories, back to his first days in Equestria. To that motherly kindness which had once before saved him from the depths of insanity and despair. Terrance gazed up into that solar alicorn's magenta eyes and remembered who she was and all she had done for him. What had he done to deserve it? What had he ever done for her? All he ever seemed to do was complain when, honestly, he had it pretty good.

Terrance flopped over onto his back and forced himself to calm down. "Just... give me a moment."

Celestia hummed, but otherwise said nothing.

The fireplace crackled. A clock ticked. Neither of them moved for some time.

"Celestia?" Terrance asked.

"Yes?"

"Before, when we were talking about fetishes... is it true that one in five ponies is into... fart? You weren't simply making that up as part of your... test?"

"No, it's true. A fifth are, in fact, into gas play." Then she added quietly afterword, "including me."

Terrance shook his head and whispered his disbelief, "that's crazy."

There was another pause in their conversation.

"How... aggressive... would you be?"

"I... want to get pretty rough with you," she admitted. "But it's supposed to be a game and I promise I would never hurt you. You're going to have to trust me."

"If... I go along with this and become your... concubine... will you keep our... sessions... to a minimum?"

Celestia whined with discomfort at his request. "I can't guarantee anything, but... I'll try. Like I said earlier, you just make me so horny."

For awhile Terrance merely laid there, thinking. Calculating. Pondering his choice.

Then his whole body went stiff. He grabbed handfuls of pillow and his toes curled and his face scrunched and his abs tightened and the man grunted from the strain. After holding that position for several seconds, much to the Princess's confusion, he relaxed, sinking into the cushion as his body went limp. And with a final exhale the stress that had accumulated until now also bled away.

"Okay Celestia," Terrance mumbled, making her ears perk. "I'll give you one session. A quick one. Just to see if..." his voice faded and he was unable to finish his thought. Especially when he peeked up at the mare and saw how large and excited her eyes were. He gulped. Hopefully he hadn't unleashed the beast.

Yet the Princess managed to control herself even as she gushed. "Thank you so much for giving this a chance, Terrance. I promise I'll pay you back for this. I swear."

He sat up and waved a hand. "Whoa whoa Celestia. All I said was... one try. I'm not ready to become your... concubine."

The alicorn wilted a little bit, but her enthusiasm was still there. "I understand. So, how do you want to do this?"

"I get to choose? I thought the whole point was that I became your toy? That you got to be in charge?"

"Not for our first time. Once you officially become the Royal Concubine I'll be more forceful, but for a simple test run I think it would be best to let you decide what happens."

Terrance rubbed his chin thoughtfully, but a second later threw his hands up, sick of thinking for today. "Let's just... do it!"

Celestia flinched slightly in surprise. "The whole game? Or...?"

"Just..." he swallowed. "Just fart on me! I need to know if... if I can take it," he justified, voice growing weaker with each word.

"No foreplay?" the mare whined mostly to herself before remembering that this was for him, not her, and shook her head at her own selfishness. "Very well. If you want to skip to the end then I will oblige." After that the Princess tilted her head and her eyelids narrowed seductively. "You know... I'm still going to enjoy this. Are you ready?"

Terrance felt his throat tighten so he could only nod.

The enormous mare's tongue slithered out the corner of her mouth and she released a single deep breath. "Then stand up. And turn around."

The man wordlessly shuffled to his feet and did as she asked. Now spread out before him was a vast cushioned landscape. It was supposed to be a lounging pillow, the pony equivalent of a chair, but for Terrance it was a near endless desert complete with silky dunes. Watching him trudge across it had always amused the Princess, much to his annoyance and probably why she consistently provided it. So he'd gotten into the habit of picking a spot and plopping down not far from wherever she dropped him off. Which usually meant he was seated near the edge closest to herself. Today included.

For a moment he admired the many rolling hills and treacherous ravines that made up the padded geography. Almost forgetting what was about to happen. At least until he heard Celestia begin to move.

There was a low brushing sound and female grunting, followed by a quartet of muffled thumps which announced the landing of each of her hooves on the continent that was her own pillow. Terrance felt his skin crawl with nervousness when there was a delay in the action. Then there came a loud clack as Celestia took a step onto the wooden floor between their two pillows. He flinched. There was another clack. Again he flinched. A massive white pillar swung into view from behind, which created a whoosh of displaced air, before settling somewhere far ahead and to the right, deep within the cushion-desert. The terrain buckled, pressed into a crater by the mare's gigantic hoof. Then its partner came in on the other side of the horizon, falling upon the world below with seemingly as little care as the first. Together the two pale monuments mangled the landscape beyond recognition, pulling the fabric between them taut to the point that even the surface as far away as Terrance shifted and he fell back.

And found himself looking straight up.

Up at Celestia's underbelly as she passed over him and cast his world in her shadow. This was only the second time a pony had ever done so. While the first time had been scary, with the pony not even knowing he was there, this time it filled him with awe. Celestia was bigger than a normal pony, which to Terrance were already enormous. So she was absolutely towering. It was like watching a moon, held up by four skyscrapers, drift across the sky. And then he saw her naked breasts. Though much lower on her equine torso than a human's, and also relatively flat proportionally, they were still quite expansive on his scale. A pair of hills hanging upside down with peaks highlighted a delicate pink. What he hadn't expected however, was their slightly darker coloration. More gray than the marble white of the rest of her coat.

Terrance blushed and shrank into himself, embarrassed to be glimpsing this forbidden part of a woman. Particularly one he knew. Meanwhile the giant continued forward.

Two additional clacks told the tiny man that Celestia's rear hooves had reached the wooden floor, but more important in the moment was the movement of her forelegs. The front right hoof rose into the heavens, permitting the plush terrain it had once warped with its mere weight to puff up and regain part of its former shape. Then it soared some distance before coming back down near the opposite edge of the pillow. Again cratering the landscape. A journey that would have taken Terrance several minutes had taken the gargantuan mare above him a mere step. Speaking of which, her left leg then copied the action. Rising into the sky, surging past his world, then dropping down again with a barely audible boom.

Terrance pushed himself to his knees, but didn't bother getting to his feet. He just wanted to know what was happening. To see everything. Yet he was interrupted by the arrival of Celestia's rear hooves.

A third white column as wide and tall as any building crashed into the silk slopes only a minute's jog ahead and to the man's right, literally reshaping the local geography in an instant. Having landed much closer to Terrance than the previous set of hooves had, the man was tossed about as the ground beneath him shifted wildly. He was rolled over and over until he was able to find a stable spot. Just in time to witness the fourth leg's appearance. It was like a meteor striking from above. It fell upon the world with enough weight and power that it created a huge depression, bending the terrain for several hundred feet. Terrance had to hold on as everything around him dramatically wrinkled and stretched, seemingly at random, merely to accommodate the goddess who now graced this once barren land with her presence. After a moment, when the chaos stilled, he dared to raise his head.

On the far side of the pillow, a location that might as well have been on the opposite side of a continent for Terrance, Celestia's fore hooves made one last adjustment. Not quite a full step, but more a shuffle to rebalance herself. Though the distinction hardly mattered. To see two of the pale pillars that extended almost endlessly up into the sky hover and drop, one after the other, each accompanied by a muffled yet still powerful thump. It was a humbling experience. When was the last time Terrance had simply watched a pony walk?

Finally, the man turned his gaze skyward.

Celestia was standing on his pillow. Even with her beautiful pastel striped tail waving through the air like a warm weather aurora, the man couldn't tear his eyes off her privates. Not that he could see them in any fine detail from this angle or distance and with her bubbly ass cheeks claiming most of the spotlight. But she was otherwise on full display. Yet the Princess chose to wait for a short time. Simply rocking back and forth as she loomed over him. The landscape creaked and shifted with her every twitch, but it was certainly much gentler than before. Tame enough Terrance was lolled into a daze by it. Until her voice made him jump.

"So, what do you think? Impressed?" the mare asked while sticking out her tongue and wiggling her hips teasingly. The motion unintentionally transferred down to her hooves, causing them to lightly bounce and the world beneath her to quake.

"Yes," he mumbled lamely, awestruck by how much of an effect such a minor dance for her could have.

Then he heard her take a breath so she could get serious for a moment. "Terrance, this is your last chance. If I go any further I... I... I don't think I'll be able to stop myself. I'm so pent up right now that, if I sit down, you are going to get all my gas. And there... is a lot of it," she whimpered. "Are you sure you want to do this?"

The man trembled as he stared upward at Celestia's menacing ass. She was going to dominate him. She was going to crush him. She was going to suffocate him. She was going to fart on him.

And he was going to let her do it.

Because he wanted to be her friend. Because she had done so much for him. Because he had done nothing for her.

Until now.

And all it required him to do... was breathe her gas...

Terrance swallowed. "I'm ready," he shuddered.

Celestia hesitated before replying. "Thank you, Terrance. I know you probably won't like this very much, but -- Remember that 'man's pride' you were talking about awhile ago? About how important it is for a man to make sure his woman is satisfied? Well, if it makes this any easier for you, try thinking of this as your 'pride'. That this is how you'll satisfy me. That by braving my farts, you bring me pleasure," she said as her body began to quiver with need, shaking even her tail. "Know that... this is what I want. This is my fetish. That my deepest fantasy is to-" she gasped and her body tensed. "My deepest fantasy... is to immerse you in my gas," she panted, muscles relaxing.

Despite the Princess's heavy breathing, there was an awkward silence while she realized how carried away she'd gotten during what was supposed to be an encouraging speech. Her cheeks soon lit up bright red with embarrassment and she quickly bent forward, face appearing upside-down, to address Terrance directly. "Sorry. I... hope it helped," she finished shyly.

For the little human it actually had. Sort of. If not entirely in the way Celestia intended. Her loss of control made it clear she hadn't lied earlier. The thought of farting on him really did turn her on that much. She was going crazy just thinking about it. Though Terrance wasn't sure how to feel about being the target of such an overwhelming mindless lust, he was also simply done with questions for today. He just wanted to get through this and worry about the consequences and everything else tomorrow.

"Yeah, it did," he assured her, sounding perhaps more confident than he really felt.

Celestia blinked with surprise. "I'm glad," she said with a delicate smile. Then she sighed. "Well, here I come."

Her head disappeared as the Princess straightened and, with an anxious jerk, Terrance looked skyward. Now it was his turn to breathe heavily as the mare's titanic rear began to descend. However, unlike with her hooves, this time she moved slowly. Carefully. Bending her knees at a measured pace even while her haunches tilted further and further. Between that and how she was definitely keeping her tail hiked, it was obvious what she was doing.

Celestia was putting on a show. Making it easy to gape at her exposed privates. Both her engorged pussy... and her hungry asshole.

Terrance gripped the pillow tightly as a mix of emotions stirred within him again. Fear being one of the stronger. Of course he knew Celestia's butt was huge, though with every passing second that fact was becoming a lot more real. How did he know that she wouldn't tip over, or miss, and those countless tons of fat wouldn't come crashing down on him? As her cheeks consumed more and more of his vision, as the shadow that surrounded him grew darker and darker, all he could do was trust her. When it came to himself Celestia always did seem to have supernatural senses. Like how she could clearly hear him from across a room. Which should have been impossible, yet she casually flexed that trick every time they talked. Did she have something similar for sight? Did she just know where he was? All he could do was hope as her gargantuan ass continued to fall in his direction.

Though another emotion certainly helped Terrance hold his ground: lust. He couldn't deny it. He was ogling the giant bubbly rear of a sun goddess. Because she had chosen him, a common nobody, to share this secret heaven with. He alone got to admire her vagina and study her anus. And, despite the danger, the man was indeed aroused by Celestia's presentation. Terrance also quickly noted that if he became her concubine he'd get to enjoy this show regularly. Which was awfully tempting by itself. If he could stomach the cost he was about to experience.

Finally, her ass reached the surface.

It was then, in that brief moment before impact, that his fear suddenly roared into blind panic. She was going to land right on top of him! She was going to crush him! And there was nothing that could stop the meteor of flesh now. Terrance futilely inched backward, threw up a hand, and cried out.

The cushion immediately beneath Celestia's ass collapsed into a crater while a ring around her puffed upward, creating a steep-walled bowl. Though the padding was a bit chilly, the Princess sighed at the softness that now comfortably cupped her rear. She then smiled as she relaxed further, shifting her forelegs and sinking even deeper into the pillow. But after only a few seconds of toying with him, Celestia decided it was time to check. So she leaned forward a little and glanced over her shoulder.

"How you doing down there, Terry?" she asked with a sassy huff.

Meanwhile, Terrance was shocked he hadn't been turned to paste. The ground had shifted so quickly and aggressively he hadn't been able to follow what happened. All he could remember of the chaos was a big bounce. Once he realized he wasn't dead, and after shaking his head to clear it, he found himself on his belly cast in a chromatic gloom. Pushing himself to his knees he began taking in his surroundings. Only to glance up and be enchanted by the solid aurora borealis waving above him.

It had never occurred to him before, but he wasn't sure if Celestia's tail actually glowed. Even now he couldn't tell. Was the dim colorful illumination coming from itself or the light filtering through it?

But his idol thoughts were cutoff by movement all-around him. The terrain started to warp and tilt again, causing his hands and feet to slip on the silky surface. A second later he was on his belly once more. Then Celestia's question reached him. "I... I'm okay," he stammered, still dazed by everything.

"I'm pretty sexy, huh?" the towering alicorn teased, wiggling her hips.

The already treacherous landscape was yanked from side-to-side and Terrance grunted as he scrambled to find a grip. When she stopped, and the world was allowed to settle, the man rolled onto his back with a frustrated sigh. He knew she'd done that on purpose and he was about to chide her for being so indifferent to his position, but froze stiff at what he found looming above him.

Celestia's asshole.

If 90 degrees was a wall and zero degrees was a ceiling, then her donut was at around 15. And it was aimed straight at him. He was quite literally staring into the center of a wrinkled circle of muscle that, for now, remained tightly sealed. Just how big was it? He honestly couldn't tell. With the mare's cruise ship sized glutes on either side of him, her sky filling tail behind, and only the top third of the gorge that was her pussy visible, it was really hard to estimate. Terrance wasn't even sure of the distance. Could a four story building fit in here or would it be barely possible to squeeze in a five story? The only thing he was certain of was that he couldn't see all of her anus at once. He had to turn his head to take it all in.

In other words, the big mare had a big asshole.

Terrance gulped.

"Terry?" Celestia's voice cracked. "Listen, I'm... about to start. If there is anything you need to say, you'd... better do it... now," she panted.

The man wasn't able to reply however, because as soon as she finished talking, the Princess shifted again. The cliffs of flesh and fur on either side pressed inward, rumpling the terrain and sending the little human into a desperate search for an anchor while the ground morphed into a line of irregular ditches. The massive mare above then held her clench for several moments before slowly releasing it along with a deep shivering breath. While the geography melted back down to a level surface Terrance sighed as well.

*

With that short surprise over, he glanced upward one last time. Her asshole was still there. Taunting him. Threatening him. Ready to go.

Terrance licked his lips in order to steady his voice. He didn't want her to hear how nervous he was. "Celestia, y-you can-"

"I'm sorry Terrance!" the alicorn gasped, completely drowning him out. "Whether you've changed your mind -- whether you're ready -- I just can't wait any longer! I'm going!!" she shouted.

The anal ring above him quickly began to bulge as an unimaginable pressure swelled behind it. The man's eyes widened and Terrance scampered backwards. Not that it mattered. The bowl created by the enormous mare's weight, combined with the slick silky material, meant that escape would have been impossible. Celestia was right. It was too late to change his mind. He was going to do this. Meanwhile, the wrinkled circle kept stretching further and further. The muscle pulled taut and strained to the breaking point. The tension skyrocketing by the millisecond.

Then it burst.

In a blink the once seemingly impenetrable barrier ripped open and a gush of wind erupted outward. While it wasn't quite enough to pin Terrance down, it was strong enough to shove him back even while seated. Staying at all upright required significant effort and using his elbows for support. The sound that came with it was also a struggle. Like an overpowered foghorn that rumbled. Loud enough that, even lasting maybe three seconds, managed to leave his ears ringing. What he hadn't predicted however, was the heat. Like the surge of air from a freshly opened oven that stung the skin and eyes for a moment.

And finally, there was the smell.

A foul odor flooded his sinuses and made Terrance recoil... but not as much as he expected. Which was followed by surprise as the man processed that fact. Celestia's gas... didn't make him beg for death. He couldn't compare it to anything either or describe it beyond "like rot". Obviously it was bad and he certainly didn't like it, yet it wasn't nearly as wretched as he'd been trying to prepare himself for.

However, while Terrance was distracted by this revelation, Celestia was already busy cooking her next fart. Even as the mare cooed aloud and her anus bulged with the new rising pressure, the man didn't notice. It wasn't until the forbidden door blasted open once more that he realized she didn't intend to give him a break between releases. He had suddenly found himself on the receiving end of her gauntlet.

Celestia's second fart was a little different. Instead of a single continuous flow, her hole kept trying to close, only to be shoved open again an instant later. As though the gas wasn't coming quite fast enough. For Terrance it was like getting hit by a rapid fire wind cannon. With gust after gust of putrid air slamming into him one after another. Each burst punctuated by a deep popping sound that refreshed his headache. He learned quickly to keep his mouth and eyes closed until he was sure it was over.

Once more the smell made him want to gag, but not vomit.

After a full five agonizing seconds, the salvo petered out just in time for him to catch Celestia mumble to herself. "Oh, that was a wet one. Hehe." Followed by a sharp inhale and a grunt.

"Another already?" Terrance whimpered as her anus began to pucker above him yet again. The Princess wasted no time pushing out her next fart.

The third one ended up being something new as well. It didn't have as much force as the first, somewhere between a strong breeze and a weak gale, and the ring of muscle didn't try to close repeatedly like the second. The mare's hole simply opened less and remained that way while the gas escaped at a steady rate through the narrow gap. As a result the sound it made was like an earthy hiss that was hard to listen to.

And boy did Terrance listen.

This fart just went on and on. By far the longest of the three. Long enough the man was forced to take a breath while it was still ongoing. Instantly he could taste Celestia's ass and his face scrunched like he'd bitten into something sour. While he was still choking the wind died down and finished with an almost cute squeak.

"Oof," the mare above him moaned before devolving into greedy panting for a few seconds. However, a moment later when the Princess suddenly stopped and he heard her grunt again, he knew what it meant.

His eyes snapped to the muscular ring still hovering threateningly over him. Yup, it was swelling. Here came fart number four. Terrance braced himself, turning his head away and tensing. Of course, if her last one was the longest, then her next simply had to be the shortest.

Celestia's anus only leaked a single gush before sealing once more. Apparently done. Not that it was so trivial for the man below. The massive mare's quick fart poured over him like a bucket of ice water. He could feel it surge across his skin and through his clothes before flowing outward and re-saturating the entire area like the previous ones. And in the aftermath Terrance realized, for Celestia, that fart had been nothing more than a puff. He'd never felt so small and helpless.

He coughed on the gas, his body instinctively rejecting the contaminated air. Yet there was nothing else available. Here, in the strangely colorful gloom beneath Celestia's ass, there was only the lingering miasma. A constant stink that made his nose wrinkle. And breathing through his mouth just traded the smell for a rotten flavor that dried out his tongue. In addition, the temperature had risen with each release until Terrance felt like he was in a desert and he was beginning to sweat.

Then he heard Celestia start talking and was about to respond when it dawned on him that she was actually monologuing. She was talking about him, not to him.

"Oh Terry," the Princess gasped and licked her lips. "Isn't this wonderful? You know, I've wanted to fart on you since we met. You're just so perfect for it. You're so tiny..." she rambled between wheezes.

Suddenly Celestia's ass began to rise. To which Terrance blinked in surprise and started looking around energetically. Was she getting up? Was she giving him a break or checking on him? The landscape puffed upward, now free of the tremendous weight. A cooling breeze rushed over him and cleared away much of the foul odor. Real light beamed in and cut through the shadows. Terrance sighed with relief, slumped onto his back, and spread his arms and legs.

But the view above was dominated by a pair of huge white furry cheeks which didn't go far before pausing. Though from his perspective they must have soared a couple dozen stories, for Celestia it was only a few inches. Then she wiggled her hips and gave her tail a flick. Brief as it was, Terrance couldn't deny he kind of enjoyed that tease.

At least until Celestia dropped right back down.

Without warning her gigantic ass crashed into the cushion with a dull thump, throwing Terrance into the air for a moment. Fortunately his entire world was a plush surface so the landing barely bothered him. However, he once again found the mare's wrinkled anus hovering over him.

Now it was Celestia's turn to sigh with relief. "Ah, that's better. Now, where were we?" she asked in a teasing tone. "Oh yeah, I was just telling you how great it is that you're tiny." Then she grunted.

The muscular ring above him puckered and tensed. It was another short puff, but it was still enough to make Terrance cough on the fumes.

"You fit so nicely under my ass," the Princess hummed. "I don't have to hold you down or bury a muzzle between my cheeks. I can just drop you on a pillow and sit. You're so convenient," she giggled. Then she took a sharp breath. And grunted.

The fart was strong and lasted several seconds. All Terrance could do was turn his head and close his eyes as he weathered the storm. As a stream of gas battered his face and coated him in a foul stink. And by the end of it he started to become aware of his growing fatigue. The man had struggled to hold his ground, to stay upright, through the first couple. By now however, he began to understand the pointlessness of it. If he sat up straight or sprawled on the ground, it made no difference. There was no enduring Celestia's farts. They were too big and too many. He wasn't going to emerge from this standing on his own two feet.

So Terrance finally surrendered.

There was no more fight left in him. The man simply went limp, sinking into the cushion and gazing up in defeat. Staring into the physical manifestation of the abyss. Staring into the mare's giant, puffy, wrinkled, twitching, asshole. And while he choked on miasma, Celestia was completely lost in her fantasy...

"Oh Terrance," she moaned. "It's almost like... like you were meant for this." She swallowed. She grunted.

Her anus bulged. Another wet fart. Slow and accompanied by countless ear-ringing pops. Each blast pounded Terrance and made him flinch repeatedly until it was over. He was sweating in the building heat and gagged on the smell that could only dissipate so much in the confined space.

"Yes," Celestia cooed. "This is where you belong. This... is how you can serve the kingdom," she growled.

The mare's hole swelled and burst. Though it was just a puff again, the gas was as hot as ever on his exposed skin and carried with it the same vile odor. Yet there was nothing he could do. Even if he called out to her, the man was doubtful Celestia would hear. So he remained on his back while the session continued.

"No, that's not right," Celestia murmured aloud. "I don't want you to serve the kingdom. I want you to serve me," she said with a quiver in her voice.

She gave him yet another fart puff that made him cough.

"No, that's a lie," the Princess grumbled to herself. "I don't want your service. What I want..." Celestia's words were lost in a drawn out moan.

A moan that lasted as long as the hissing fart she unleashed on Terrance. The stench was getting bad too, renewed and strengthened with each dose. Though the man tried to distract himself from his suffering by paying attention to the alicorn's monologue. Despite his situation, he was genuinely curious what the hell she was talking about.

"What I want," Celestia croaked. "Is to... cover you in farts. In... my farts," she gasped.

The next one was strong. The ring of muscle opened wide and a rotten gale poured out. Terrance could feel it pressing down on him and it started getting harder to breath. A feeling that barely lingered even after the eruption settled. Then the man peeked upward timidly, afraid of being ambushed without some kind of warning. The mare's anus was flexing, going tight then loose, seemingly for no reason. Terrance couldn't help making a pitiful whimper. How much more could she have?

Celestia squeaked above him and his world shook as she moved. "I want to fill your lungs with my gas," she explained huskily and hit him with yet another quick puff. "I want every breath you take to be one of my farts!" she squealed. Then moaned. Then farted again.

Once more he faced a "wet one" that battered his body with a rapid barrage and filled his ears with booming pops. By now he was drenched in sweat and the air was heavy with miasma. Terrance started to feel dizzy and a few spots danced in his vision. Was he in trouble? His thoughts were slow and the only thing he could really focus on was the asshole above him and the voice of Celestia in the distance.

"I'll have a little harness made for you so you can dangle from my tail," she cooed lustfully. "That way, I can keep you close to my ass at all times. Whenever I sit down, whenever I travel, you'll always be there to catch all my farts," she sighed.

Her anus let out another puff, but Terrance could scarcely react to it. He was too drained to even cringe much anymore.

"Once you become my concubine, I want you to experience-" Celestia had to stop and swallow. "I want y-you to experience every ounce I can b-brew," she stuttered, voice growing higher pitched by the word. Then she began to pant, each more desperate than the last. "T-Terry... I l-love you. Now prove that you love me back. B-breathe my farts! Drown in my gas!" Then she cried out.

Her hole exploded. Terrance couldn't say for certain if it was the biggest or the strongest, but it was definitely large. It bore down on the man like a raging storm. Even when it was over the smell that attacked his nose intensified to the point that he knew he wasn't getting enough oxygen. Terrance would have panicked and called for help, but he was so tired and everything was so heavy. The spots in his vision grew larger until everything went black.

Terrance jerked awake and for a moment thought he was still under Celestia's ass. But a quick glance upward revealed a clear sky. Well, at least until the ordinary ceiling far far above. The man sighed and clutched his head as a throbbing ached in his temples.

"Have a nice nap?" came Celestia's gentle greeting.

"Huh?" the man mumbled in surprise.

Terrance glanced about in search of the Princess. While he did so however, he couldn't help noticing something strange about the surface he was laying on. It was soft, but it was a different kind of softness from the pillow. This ground had a grass-like texture. He ran his hands through some of it curiously, feeling the individual blades tickle his skin as he did so. He kind of enjoyed the feeling.

Celestia giggled. "I'm back here."

The man's head tilted nearly upside down and he did indeed find the mare. But the way her neck bent was odd. There was a sharp curvature towards himself that hurt his brain trying to understand. So Terrance grunted as he rolled over and slowly pushed himself to his knees. Though he really didn't need to. The mystery was solved as soon as he saw the "grass".

It was white fur.

He was on Celestia's belly.

"I... thought I was going to die," Terrance whispered, staring at his shaking hands.

Her ears fell. "Of course not. I told you to trust me and I promised I wouldn't hurt you."

He peered into her eyes. "How?" he rasped. "You were... out of control. How would you even know I was in trouble? Or stop yourself?"

Celestia's eyebrows lowered with guilt. "I... never told you? Whenever we're together I'm always keeping track of you with a spell. Location and condition. If you're hurt an alarm goes off in my head. Not even... not even my lust would keep me from saving you."

Well that explained her supernatural awareness. The man sighed, not sure what to say to that. It had been a very long day. So he slumped into a seated position. Then simply fell backwards and sprawled amongst Celestia's fur. To which she chuckled.

But he heard her lick her lips nervously in the silence that followed.

"Terrance?" she asked quietly. "How... was it?"

The man cringed and his jaw went stiff. "Bad. And... you said... things..."

He heard and felt Celestia shuffle uncomfortably. "That was just the fantasy Terrance. I... didn't mean any of it. I just got carried away."

"I know," he replied dismissively.

"So... have you made a decision?"

"I... I..." he couldn't finish his sentence. He growled at his uncertainty and forced himself to sit up again. Then he aimed something like a scowl at the Princess who looked afraid and worried. "I need time to think, Celestia. This has all been... just too much."

The mare sighed and her form wilted. "Okay Terrance. There's no rush. I'm quite... satisfied right now." Then she snorted weakly. "Guess it was too much to hope."

He shrugged.

"But... don't forget about Luna," she added ominously.

Terrance shivered at the implications. "Does she... also have...?"

"Yes. We are sisters with much in common. Not all, but a lot."

Terrance groaned and shook his head. "This is... too much..."

"How about we just cuddle for awhile. Would that make you feel better?"

The man actually snickered at the sheer silliness of her suggestion. "You literally just gassed me unconscious and you're offering cuddles?" he joked sarcastically.

But Celestia perked up at that. "You're right. I promised to pay you back for this and we haven't even discussed your fetish." She eyed him seductively and her voice dropped an octave. "So tell me, Terrance. What turns you on? What can I do for you?"

"Uh..." the man droned, caught completely off guard.

Today was never going to end.

Author's Note

While I'm proud of most of this story, the intro is still a sore spot for me. It's meant to explain Terrance's current situation, imply how he got here, and foreshadow the fart experience to come. But it feels too random and disconnected from the rest of the story. For example, the exploration of pony fart culture hits too sudden and doesn't actually seem that relevant to Celestia's interest. She could just be one-of-a-kind, why does it have to be a common fetish among ponies? While I intended it to be a soft opener, to prepare the reader and make it easier to believe ANY pony could be into fart play, in the end I just don't think it worked very well.

Other than that, there were two specific things about fart play, and how I've seen it presented elsewhere, that I wanted to tackle with this story.

One: the torture. Why does every fart fetish story portray the gas as being literal air-born acid that makes the recipient beg for death? To me it always came across as excessively cruel and unrealistic. So I toned that way down in my attempt.

Second: willingness. Why is the dominant partner always a complete psycho who tricks, kidnaps, or otherwise forces their kink on their partner? And why is the submissive participant always a victim or totally into it? I guess it's because writing a realistic conversation of someone trying to convince their partner to huff their farts is REALLY FREAKING HARD TO DO without making the dominant partner seem like a manipulative freak.

Even I kind of gave up after a few rounds of editing. I tried so hard to make Celestia NOT seem like she was forcing her fetish onto Terrance with carefully constructed emotional arguments, but I genuinely don't think it's possible. The big mare simply feels manipulative, but maybe that just comes with the fetish. Oh well, at least I gave it my best shot.
