Satou Kazuma was in a foul mood.

When he had first decided to come to this fantasy world, he’d thought his new life would be a breeze. He’d thought he would easily take down the Demon Lord, become incredibly rich and famous, and live a life of extravagance and luxury. He certainly hadn’t expected to make zero progress after a month, or that he’d be staying in an old, rickety barn and sleeping on a pile of straw.

“This is all her fault,” he muttered to himself angrily. He could’ve come here with all kinds of powerful items, enchanted weapons or magic abilities, but no. Instead he’d picked a useless, airheaded Goddess, who he’d once seen cry because she dropped a 100 Eris coin down the drain that was going to be used for ice cream.

She constantly made trouble for him while at the same time demanding his praise and worship. Even now she was in the local tavern, squandering their money – hard earned, after a gruelling day completing kill quests – drinking and partying.

“I should have taken that cursed sword,” he grumbled. Suddenly there was a crash as someone stumbled their way into the barn, and he glanced up indifferently. “Speak of the devil.”

“Hey, Kazuma!” Aqua called out happily. She approached their shared bed swaying slightly, clearly tipsy but not quite drunk. “You missed a great party! Why didn’t you come join in?”

“I’m not in the mood.”

“Heh, you don’t like parties? Is that because you’re a shut-in NEET? Hey, Kazuma.” She poked him when he didn’t respond. “Kazuma. Kaaa-zuuu-maaa.”

“Just shut up, will you? I’m trying to sleep.” He lay back and covered his eyes with his arm, ignoring her.

“Tch, you’re so boring. And rude. Stupid.” Aqua sat down next to him, not bothering to change out of her usual blue dress and extremely short miniskirt (under which she wore no panties). Suddenly her belly rumbled, and as she shifted next to her partner she accidentally relieved some pressure with a small, soft fart.

Brrrt

“Oops. ‘Scuse me!”

“Ugh, what the hell? Did you just fart?!”

“Hehe, yeah.”

“God, you’re such a slob! You think I want to hear that?” One tiny fart really wasn’t that big a deal, but Kazuma’s pent-up frustrations were being released all at once. “Everyone knows girls don’t fart, so what does that make you? A gross old hag or something?!”

“Hah?! I don’t want to be called that by a loser like you!”

“Ugh, whatever! Just don’t even talk to me anymore, I’m going to sleep.” He rolled over and faced the other way, too irritated to even continue their conversation.

“You’re so mean, Kazuma! Don’t get mad at me just because you’re a failure as an adventurer!” She crossed her arms and pouted, annoyed at being ignored, before continuing quietly. “I’m not a slob, stupid. I’m a divine Goddess. And that means every part of me is beautiful and worthy of worship, even my farts.” Suddenly she had a devilish idea, and began to grin mischievously.

She got up and clambered awkwardly over next to him, shifting until she was next to his head. He obviously noticed her shuffling around next to him (at one point she almost kicked him), but was stubbornly determined not to look back. He therefore didn’t notice Aqua squatting directly over him, only a few inches separating his head from her butt.

Pfffffffffffffffft

Kazuma felt a warm breeze tickle the side of his face, just before an absolutely rancid scent flooded his nostrils. Gagging on the taste of sour beer farts, he spun around and looked up to find his vision dominated by Aqua’s shapely ass.

“Hahaha! Oops, looks like I did it again! Sorry, Kazuma!” Said Aqua, sounding distinctly unapologetic.

“Bleggh – what the hell are you doing, you psychopath?! Get your stinky ass away from me!” He grabbed Aqua’s legs and tried to push her away, but only managed to knock her off balance; she immediately lost her footing and fell on top of him, now fully sitting on his head with his head squashed between her cheeks.

“Woah, somebody’s eager! So you want an even closer whiff? But I thought you said my ass was stinky?”

“Mm mmm!” Came Kazuma’s muffled reply. While Aqua did take care to bathe daily, they lived in a fantasy world without access to modern shower gels, soaps and body wash. So after a full day of adventuring and partying, her ass had an earthy, acrid scent, and was also quite sweaty. That, coupled with the lingering scent of her most recent fart, meant this was definitely not a place he wanted his nose to be buried in.

“Oh wait, I get it! You’re finally recognizing me as a beautiful Goddess, and want to prove your devotion by worshipping my ass! That’s right, isn’t it?” She giggled evilly. “Then allow me to baptise you, my newest servant! Inhale your Goddesses’ divine wind!”

Frrrrrrrrrrrppppppppppppt

Unfortunately he had little choice. He was so deep in her crack that the fart had nowhere to go but his nose and mouth, forcing him to take slow, pained breaths of the rotten gas. He tried again to push her off, but for some reason couldn’t gather any strength in his arms – he didn’t know if it was some kind of ability, or the sheer stink sapping his energy, but he couldn’t budge her an inch! All he could do was lie beneath her, breathing, gagging and listening to her obnoxious laugh.

“Hahahaha! Good boy, good boy, keep sniffing!” Aqua released another squeaker, happily watching her partner’s legs flail while enjoying his hot breath in her crack, and his futile attempts to push her off. She was surprised by how fun it was to humiliate him; she was originally just going to fart on him once, but she hadn’t thought it would be this entertaining!

After a few more ass-blasts, she decided it was time to start wrapping up for the night. “Ok Kazuma, your benevolent Goddess has decided to show you mercy. If you apologise for your earlier rudeness – you’d better throw some atoning kisses in there, too – I might decide to let you off the hook.”

Aqua sat up, lifting her butt a few inches so she could hear him speak. His first instinct was still to disobey and insult her, but a small poot in his nose reminded him not to push his luck. Deciding he would rather swallow his pride than swallow her farts all night, he sighed and began, begrudgingly, to beg her pardon.

“…Ok, ok. I’m very sorry I called you a gross hag with a stinky ass.” “Even though you definitely are.” “I hope you can find it in your heart to forgive this foolish mortal, kind Goddess Aqua-sama.” He grimaced and reluctantly planted a soft kiss on each of her round, jiggling cheeks, then pulled back and waited for her reaction.

Brrrrrrrrrrrrrrrppppppppppppt

“Hehehe! Sorry, but I only said I might let you go!” Her reaction was to quickly drop back down and rub her crack up and down Kazuma’s face, smearing him in her newest noxious blast while he seethed with rage. “Hmm, I guess that was a good apology though, very humble. Ok then, let’s make a deal! I’ll get up and stop farting on you for the rest of the night, if you promise to become my permanent butt-slave! How does that sound?”

“Her what?! She’s even crazier than I – ” He paused suddenly, having just had a great idea. All he had to do was “agree” to this insane bargain, and she’d get up immediately, no questions asked? This was a golden opportunity! “It’s not like I’m signing a contract here! When she asks me to hold up my end of the deal, I’ll just refuse! I’ll pretend I have no idea what she’s talking about!” He thought to himself smugly.

Aqua wiggled her butt above him impatiently. “Well, what’ll it be? If you want you can just say “no”, I have lots more tasty farts for you to – ”

“No wait, wait! I’ll take the deal!”

“…Wait, really?” She twisted around to look at him. “You promise?”

“Yeah, yeah, I promise I’ll be your butt-slave from now on. Happy? Now can you please get off me?”

Aqua paused for a moment, before her face split into a wide smile. “Sure! Wow, I can’t believe you actually agreed to that!” She patted him on the head affectionately, then finally clambered off his face. He immediately sat up and took several deep breaths of blissfully fresh air, thankful his torture was finally over.

“Ok then, no more farts tonight, as promised. I’m gonna get some sleep, and you should too! We’ve got a big day tomorrow, after all.” She lay down next to him and peacefully closed her eyes. “Ahh. I can’t believe I actually have a servant again! Hehe.”

“Oh, Aqua. So naïve,” Kazuma thought as he too lay down to rest, obviously having no intention of fulfilling his promise. The look of disappointment on her face tomorrow would no doubt be satisfying, but he’d need something more to repay all the smelly torment he’d endured tonight.

Before long they both drifted off, Aqua dreaming optimistically about the future and Kazuma still plotting, his head filled with schemes of revenge.

The next morning, Kazuma was woken by a beam of sunlight shining through a crack in the barn roof. He slowly stretched, brushed straw off his clothes, and yawned – then gagged slightly at the bad taste in his mouth. The rancid flavour on his tongue brought back the memories of last night, of being relentlessly gassed by his useless partner, and immediately put him in a bad mood.

“Well, at least I didn’t wake up to a fart in the face,” he muttered to himself. He glanced to his left to find nothing but straw; apparently Aqua was already up, and had probably gone into the nearby tavern for breakfast. “Guess I’ll go find her. I can’t wait to see the look on her face when I break my promise!”

As expected he found her in the tavern, sitting on a stool at the bar. Aqua’s miniskirt was so ridiculously short he could see the bottom of her ass-cheeks and crack, and he shuddered involuntarily at the sight, experiencing smelly flashbacks.

“Thinking about it, she was a bit tipsy last night. Does she even remember what happened?” He wondered as he entered the room. She heard him approaching and looked over her shoulder, smiling when she saw him.

“Aha, there’s my newest servant! Are you excited for your first day of ass-worship?”

“I guess she does.” There were a few snorts of laughter from the other patrons of the bar, causing his cheeks to redden with embarrassment. “Huh? What are you talking about, you idiot?”

“You promised to be my butt-slave, remember?” She reminded him happily. “Ooh, and I have your first fart of the day ready! Come over here and smell it!”

Kazuma laughed derisively, preparing to mock her for being stupid enough to trust him. But before he could speak, something strange happened; his body moved on its own! He automatically fell to his knees and crawled over to Aqua, his muscles ignoring every attempt he made to resist or stand up, and only stopped when his nose was nestled right between her cheeks! He couldn’t move!

“Wha – what the hell?!” He asked, bewildered.

“Hm? Are you surprised? This is what you agreed to,” Said Aqua. “Wait a minute, you know that promises made to Goddesses are magically binding, right? You have to keep them, like it or not!”

“…Uh oh.” He urgently tried again to will his body to move, with no success; his head might as well have been chained to her ass.

“Here it comes! Deep breaths now!”

Fffffffrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrraaaaaaaaaaaaaaaappppppttt

A long, hot blast battered Kazuma’s face, which he immediately and enthusiastically sniffed up. The pungent, bitter taste made him want to vomit, but his body wouldn’t allow him. He was compelled to kneel still and sniff as though his life depended on it.

“Ahh… haha, stupid Kazuma! I bet you thought you could just break our deal, huh? Well, maybe now you’ll learn your place! I deserve to be worshipped, and you deserve to worship me!”

Kazuma turned bright red as the entire bar erupted in laughter, amazed at his apparent willingness to humiliate himself. But Aqua’s laughter embarrassed him most of all, her delighted giggles sickening him almost as much as the stench of her ass.

“Ok, this means war!” He silently raged. “I will definitely break this useless Goddesses’ spell, and make her regret humiliating me like this! For now, I just have to endure, and my chance will surely come.”

“Ok butt-slave, here comes your next one! Let’s have some kisses this time!”

“…My chance will come, right?!”

Bbbbbbbbbbbbbbrrrrrrrrraarrrrrrrrrrrrrrrt
