Sister's Fart Slave: Part 1
Author: Daethor

A friend once told me, "Pretty girls never fart." To this day, I have never heard such an untrue statement. At the age of 16, being scientifically minded, I decided to test this theory on none other than my own sister. I was mature enough to recognize that my 19-year old sister Linda was attractive, it didn't hurt that many of my friends had made nasty, lewd comments about her. She was tall and curvy; medium breasts with wide hips and a big, round butt that I made fun of all the time. I was somewhat of a prankster and before one of her dance classes, I decided to give her a devious treat. A few days ago, I had purchased a few fart lollipops and some fart powder from a local gag store. I snuck some of the powder into her water bottle and under the pretense of being a nice brother, offered her a lollipop. Needless to say, with that in her system (not to mention the copious amounts of cabbage she eats) and the movement from all that dancing, her dance practice stunk pretty bad, figuratively and literally.

"Wow, sis. Never knew you had it in you," I snickered as we drove home and she continued to release her gas. "Of course with that huge ass of yours, it's no wonder they come out so stinky."

She rolled her eyes said, "Shut up Frankie" and continued to drive, too embarrassed to keep up the brother-sister fighting. 
When we got home, I followed her up the stairs and got a huge butt bomb right in my face at the top of my stairs for my teasing. "Hope you enjoyed that one, little brother. There's plenty of more where that came from." Wow, did that gas ever reek; I was so stunned, I tripped over the last stair and the contents of my jacket pockets flew out. Silently, I cursed. I had kept the rest of the packet of powder and two more of the lollipops in their wrappers in my jacket and now they were lying, plainly visible, on the floor.

As I scrambled to pick everything up, my sister snagged one of the lollipops. As she read the label on them, her eyes widened. "You little bastard," she snarled, "do you have any idea how humiliated I was tonight? Get in my room right now, or I'll tell mom and dad what you have hidden under your bed when they get home."

It was my turn for my eyes to widen; I had a veritable library of porn hidden in a chest under my bed. My sister sauntered behind me sucking on another fart lollipop as I scrambled to her room. Why was she having another one? Wasn't she mad at me for giving her the first one?

"Lie on my bed," she said when she finally entered the room. As I did, she grabbed a roll of scotch tape off her desk. "So you think making me fart is funny? We'll see how funny you think it is in a few minutes. Where is that fart powder? I saw you grab it." Another whiff of gas hit my nostrils as I grabbed it from my jacket and handed it to her. She finished the lollipop, grabbed her water bottle and poured the remaining half of the powder in.

"Now put your head on the pillow, you're going to keep me company as I watch TV," she said. Ok, I thought, this won't be so bad. She probably just wants me to suffer from smelling her gas too, but what was that scotch tape for? I looked on in fascination as she stripped down to her bra and panties, and then lost the panties as well.

"Open your mouth little brother," she sneered. I obeyed, wondering where all this was going. She shoved the underwear into my mouth and started taping my mouth area with scotch tape. I can't quite describe the taste of those boy shorts as they entered my mouth. I guess the best way to describe them is a rank mixture of the taste of her farts and sweat, but the combination of the two was greater and stinkier than the sum of it's parts.

"What are you doing?" I tried to ask, but her underwear muffled my voice and made me gag so I couldn't speak. "Aw, poor baby brother can't talk? Well, just sit back, relax, and enjoy the show."

She clicked on the TV and climbed onto her bed...and then climbed on top of me. She reverse straddled my face, with that potent posterior of hers pointing straight at me. My eyes widened as my field of view became increasingly filled with her ass until finally she was practically smothering me. "Oooh. That feels so good with your nose up my crack," she moaned. "Can you smell the effects of your little prank, brother? " I sure could. I thought her panties tasted bad; it was nothing compared to the smell of her ass. Suddenly she laughed. "You're gonna regret buying that stuff now Frankie. Heh, Frankie the Fart Face. I think that's gonna be your new nick name." My heartbeat skyrocketed as I suddenly realized what she was doing and why she was using the stuff I bought. She was going to fart on my face!

PRRRRRRP! PSSSSSST! BRRRRRF!

I held my breath as the hot gas streamed toward my nostrils. My sister laughed and said, "Oh, you're not getting out of smelling that delicious gas little bro." She sat down harder on my face until my nose was pressed against her asshole, forming a seal that kept the gas hovering around me. She pushed down on my stomach slowly but firmly until I had to breathe. As I inhaled, I realized my mistake. Holding my breath made me need to breathe more, which meant more of her noxious fumes. I gagged as the smell seemed to go on forever. Finally, she lifted her ass, letting in some much needed, relatively fresh air.

"How we doing down there little brother? You know, with mom and dad gone the whole weekend, I could do this all day! What's that? Speak up little brother!" She laughed, knowing I had to obey her commands and knowing I couldn't speak. The torture lasted for hours. Sometimes she would go ten minutes without passing gas; other times, she would let loose with a smelly salvo of ass gas that almost made me black out. Around 12:00, she decided that she wanted to go to bed, but that didn't mean I got a break. She left me so she could grab a midnight snack of refried beans and cheese and soon returned with some old jump ropes. "These are for you, so that you won't escape in the middle of the night; and if you do, I'll make sure mom and dad know what a pervert you are." She quickly tied me up so that I was lying on my side, barely able to move an inch. Her last act was to cover me with her blanket so I would be in a perpetual dutch oven the rest of the night. At least she was kind enough to remove her panties from my mouth, but that just meant I had to taste her farts as well. "Good night, little bro. Sweet dreams." Throughout the night, I fell asleep only to be awakened by a particularly nasty blast, which then made me pass out. I was officially my sister's fart slave.
