Fluttershy's Fart Slave

You wake up from your slumber when the lid opens up the very next morning. A plethora of birds are all singing outside, and the morning sunlight through the windows are bathing the room in a pleasant lighting, though it's still much too bright for you to handle.

Above you stands fluttershy, looking down at you. She's holding a whip in her mouth. She's wearing black stockings, and a short, black skirt to match. This really was a fetish for her.

"Don't look at me like that." She says, dropping her whip in the process.

"I'm going to fart on you, now!"

She sounds pretty confident, much to your surprise.

"It's going to be very stinky... B-But not that stinky. I don't want to be too harsh on you, so I haven't eaten anything bad at all. They might be... Somewhat mild, really... Bu-bu-but, still! My farts are always stinky, even the milder ones. I'm just a very stinky mare overall actually! A haven't showered in days to make sure my asscrack was nice and smelly for you as well! But only two days, as I don't want you to be overwhelmed at first... Still! It stinks down there, got it?"

She's so bad at this it almost baffles you...

She turns around and lifts up her skirt with her tail. You get your first look at her ass. It's a bit larger than you expected, she's clearly quite a curvy mare. Looking rather fit from the front, perhaps with just the slightest hit of a belly, she seems to have put all her fat in the right places. She's wearing white panties, so you can't really evaluate her "torture instruments" for now.

"If you don't sniff it, I'll punish you, got it!? I won't be too harsh though."

She sits down. Her ass pretty much exactly fills out the leather seat, blocking away the light, and making your torture chamber air-tight. She separates her legs, letting the light inside and allowing her to look in. She's about 20 centimeters above your face. She looks at you with her red face and wide open eyes.

"I should probably lift your face up a bit, so you can smell my ass a bit before... I start... farting."

She leans to her left and you hear some sort of mechanism being activated, you feel your upper body being lifted, you face always being kept horizontally. Soon, your nostrils are ever so slightly touching the fabric of her underwear.

"Sn... Sniff it!"

You inhale. The air you breath is tainted with her ass-musk. It smells earthy, dirty and sweaty. You will admit she was right, it stinks down there. It's not horrible torture to smell. It's mostly just unpleasant, but it's unpleasant enough for you to make a rather dissatisfied sound as you smell her buttcrack.

You can hear Fluttershy huffing and panting above you. She's loving this.

"Tha-tha-that's right! You better smell my asshole, oh my... K-k-keep sniffing it, or I'll, I'll, I'll. Just sniff it okay."

Your nose is only millimeters away from the unwashed anus, hiding behind the thin layer of fabric. Suddenly she rises.

She wiggles her butt, and scooches her tail around, she works the panties off of her body, revealing to you her bare ass. Her yellowish anus is not visible filthy, outside of what's to be expected from a butthole. Her vagina is rather large, but it looks very tight. She's probably a virgin. Wouldn't surprise you since she's so shy.

She picks up her panties from the floor, turns around and holds them up to your face.

"Open your mouth." She says.

You do as you're told, and she slides her used underwear into it, making sure her ass-part is on your tongue. She's probably only worn them this morning, so they are not that dirty. Still, the faint taste of musky butthole is something you could've been without.

She lowers your face down into the box a bit again. Then she sits her bare butt down on top of you. She spreads her legs and looks down at you over her thick cunt. She looks quite embarrassed. Her snout is bright red, and she looks at you in pity.

"Brace yourself. It's about to get very stinky down there. I really meant what I said when I told you I didn't make them stinky on purpose, my farts are just naturally this bad."

She closes her legs, leaving you in darkness. You can't see a thing. You hear her utter an adorable little tensing noise.

A moment later, she farts.

A long silent fart escapes her anus. The hot, smelly air blows across your face and fills your tiny chamber with her fart stench. It's so stinky that as you take your first breath of it, you gag into her panties. It smells horrible. THIS was mild to her?

It's like rotten boiled cabbage, being blown your way by a fan. Sniffing her ass was bad, sniffing her fart was unbearable. You wiggle and moan. You're tearing up.

Pfffffffffffffffffffffffffffffffffffff

Another thick fart cloud, equally as stinky as the last reinforces the smell in your torture chamber, and it's immediately followed by a third, a fourth and a fifth filthy cloud of her stinky ass gas. The humidity rises. The air you breath might as well be green now, there's probably more fart than oxygen in it.

You can hear her tense up, pushing hard.

BRRRRRRRRRTHHHHHH

A thick, stinky fart erupts suddenly out of her backside. It hits your face like a punch made of air. It's tangier than it's predecessors.

BRRRRRRRRRRRRRRRRRRRRRRRRRTTHHHHHHHHHHHHH

It's soooo stinky.

The farting slows down. Eventually, with just a tiny puff of her foul air, it stops. She sits on top of you, keeping the farts from leaving the chamber and forcing you to keep smelling their lingering stench. After a while, she spreads her legs to check on you. You notice the dark yellow-brownish cloud of gas hanging in the air around you. Her farts are so bad they can be seen by the naked eye. She looks aroused, worried and ashamed at the same time.

"Were they... Bad?"

You have a pair of her panties in your mouth and can't tell her how horrible they were and still are from where you're laying, but the bit of gas that leaks out from between her legs, making her cough and close them again, should answer her own question.

She gets up and quickly closes the lid, trapping you with the smell.

"I bet you can still smell that when I come back with the next batch of farts. I'm going to try to make them stinkier now, understand? I'm going to stink you up so much you'll forget what pleasant means."

With those words of confidence, she leaves you to bath in the fart stench until she returns.
