Fluttershy's Fart Slave

You've been smelling her farts for hours now. The thick cloud of her stinky gas has been dwindling away the entire time, and it's now just like being in the same room as someone who farted far away from you. It's bearable.

Suddenly, light. The lid is open and Fluttershy's ass fills your vision. The light turns back to darkness as she sits down. She spreads her legs and looks down at you. She looks a bit concerned.

"Are you... Ummm, Okay?"

You still have the panties in your mouth, so you can't answer really give a good answer.

Instead, you just utter a pretty pathetic "Mmmhh." She looks relieved, like she was afraid you had died or something. Slowly, her concerned expression turns devious. She smiles at you with an ever so evil grin.

"Are you ready for it to get much, much stinkier, you pathetic little fart sniffer? I'll never let you out of here. You're just a place for me to fart, now."

You break down into tears, moaning and crying as you realize this is actually your life now.

Your sudden breakdown takes Fluttershy out of character.

"I- I mean. I'm.... Oh dear. Just because I'll never let you go, doesn't mean that I won't let you have enjoyable moments every now and again. You'll just, never, be able to see anypony you care about again."

She looks sad for a moment, but she's quickly taken out of that as well as her stomach growls loudly. She quickly closes her legs.

"These farts might be hard to handle, so breath carefully."

A moment after she says that, your face is showered in a bassy torrent of her ass air. Her gas feels humid and warm as it blows across your face.

The moment you take even the tiniest sniff of that deadly cloud, you almost throw up in your mouth. It stinks...

It's much, much worse than her previous ones. It smells like rotten eggs, it's tangy and incredibly potent.

She farts again, raising the potency of the harsh smell.

"These are some of my favorite farts. I really like the egginess of them, I think they're really stinky, and they keep stinking for a long time, so when I close the lid, you'll probably be smelling them for quite a while. I will give you these a lot, so try to get used to them."

Brrrrrrrppppthffffffff

Her sulphuric anus bathes you in another green cloud rotten egg stench.

You cry and wiggle, as you're forced to inhale the deadly gas.

She farts again and again, constantly adding to the already seizure inducing stench in your toilet chamber.

The thick cloud keeps getting thicker, and thicker. Fouler, and fouler. It's so stinky now that you are afraid that you really are going to throw up.

"I know how much it stinks, but just keep sniffing it like a good fart slave, and I'll make it even stinkier for you."

Bbrrrrethhppppffffffff

BRRRRRRRRRthhhhhhhhhhffffff

Brthhhhhhhhhhhhfffffffffffffff

It's too much to handle. You throw up a little in your mouth.

Her farting stops. She keeps sitting on top of you, letting you soak in the rotten stench. After couple of minutes she rises and quickly closes the lid, retrapping you with the hot, disgusting cloud of fart gas.

"Have fun down there."
