My Lil Sister
by Unknown

Hey, everyone. It's been a while since I posted a story so I thought I'd write about how my sister has treated me since she found out about my fart fetish.

To start off, her name is Beth and she's 3 years younger than me. She's about a foot shorter than myself but she's stronger than me, she's very athletic too. She's also got a pretty big butt... :)

She first found out about my fetish when she came home early from soccer practice one day and walked in on Kelli farting in my face. Now, for those of you who don't know, Kelli basically uses me as a fart slave once in a while, whenever she feels like it more or less, and this was one of those situations. I was tied spread-eagle to
my bed with a pair of her dirty panties shoved in my mouth so I could, in her words, have the smell of her ass on my breath when she was done with me. She didn't tape my mouth shut, though - she knew I'd be a good fart sniffer and inhale it all through my nose and she liked me kissing her butt thank you.

Back to my sister, though - she walked in right as Kelli was ripping butt on my face and just stared at us in shock. I couldn't see her, so I didn't know who it was, but my cheeks probably went about 10 shades darker red than they've ever been just knowing we'd been caught by someone. After a moment she asked Kelli what the hell we were doing, and Kelli decided to explain my fetish to her and invite her to come sit on my face. Now, I should probably tell you, my sister LOVES to pick on me, but I really didn't want her to sit on my face or fart on me! I mean, this is an incredibly sexual fetish of mine and this is my little sister we're talking about! So I was under Kelli's butt frantically shaking my head no, and my sister saw this, so she laughed and took Kelli's invitation.

Unfortunately for me, I had some duct tape near my bed, so the two of them quickly put a very thick layer of duct tape over my mouth, too thick for me to push it off with my tongue, and then Beth sat on my chest facing my feet and looked back at me with the most evil grin. As I said, she had just gotten back from soccer practice, so I could already feel the sweat on her butt against my chest and I whimpered helplessly. She started moving her sweaty rear towards my face and just said, "This is going to be fun, Dani!" I disagreed, at the time.

When Kelli sat on my face, any buttstink (as we call the various scents associated with butts) she had brought me so much euphoria and pleasure. But knowing I was sniffing the fumes off my sisters butt just brought me a lot of disgust, although it's still buttstink, so those feelings of pleasure were still there. She wiggled and rubbed her big, stinky butt all over my face and her thin, cotton boy shorts that she wore under her soccer gear was not protecting me from the smell or the sweat at all - my face was practically being used as a sponge for both.

The very mixed feelings I had about sniffing her butt - the intense disgust knowing this was my little sister's rear I was smelling and the intense pleasure I have for sniffing stinky butts and farts, along with a kind of naughty, taboo enjoyment because of the two - made the 10 minutes or so until she farted torture. Now, I should probably tell you, my sister has some of, if not the downright most smelly farts I've ever smelled. Even across the room, they're very strong. It doesn't help that she's quite a tomboy and doesn't do the best job showering, either.

"Pfffffffffft." She released a long, airy fart, and it had nowhere to go but up my nose. As the warm, disgusting, eggy fart went through her dirty, sweaty butt, the smell intensified, and I moaned, both in immense pleasure and disgust. Kelli, laughing her ass off, coughed when the smell got to her, and here I was, forced to inhale nearly all of it through her shorts. She rubbed her butt up and down my face, smearing in the smell, while keeping my nose between her cute, smelly buttcheeks. She farted again shortly, this one very bubbly and gross sounding, and somehow even stinkier, then giggled. I was humiliated, yet getting more and more aroused. There was something so sexy, yet so nasty and dirty, about being used as a fart cushion for my little sister.

She giggled and quickly pushed out another stinky fart, then ordered me to sniff it up. I obliged, not that I had a choice with my upturned nose forced against her butt. I stayed there for hours, her and Kelli bringing my fart slavery and humiliation at the hands of their dirty, smelly butts to a completely new level. Following Beth's discovery of my fetish, I was very reluctant to let her rip her naughty, cute, smelly toots in my face, but she was stronger than me and would force me to anyways.

As time went on, I learned my place. Now she just points at her cute butt and I'll crawl up to it and push my nose where it belongs. Sometimes, she just has me sniff her stinky rear end for hours on end. Sometimes, she'll "Gas me" as she calls it until her eggy farts are all I can smell for a looong time. I love it, though. I'm her fart slave and we both know it. I'll always enjoy letting her make my face reek.

I know not everyone likes hearing stories about sibling and I apologize. If it makes you feel any better, it's never been anything else than butt and fart torture; we've never done anything very sexual aside from that.
