The Night I Became My Sisters Fart Slave
by XSlapper80X

PART 1

So let me just give you some insight as to what's going on. I live with my parents and my younger sister in a small town of Arkansas. I towered over her with her being around 5-5’2 and me being 6’0. My parents were both around 5’9 so being the tallest one in the house was always fun. I could do things the other members couldn't like reach things, dunk a basketball, mand being able to brag about how tall I am. I was quite the ladies man with a girlfriend of nearly 8 months. I was well groomed as well with an undercut and a slight amount of facial hair. My hair and my eyes were a dark brown and my skin was a darker tan. Even though I was Caucasian sometimes it was hard to tell. I was pretty strong, being in football and track, with a squat weight of 200 and a bench of 145. Considering I weighed 121 I thought my weight was pretty decent. My sister on the other hand, she was not very strong. She was around the same skin color as me with long dark brown hair with some lighter color streaks in it. She had baby blue eyes and, even though this will sound weird, a nice bubble butt. She played volleyball and that's when I first noticed it, popping out of her really short volleyball uniform. Her breast were a decent size with a bra the size of B cup. She enjoyed running with me sometimes during track but I ran hurdles and she ran long distance so we didn't see each other too much at practice but I took us home everyday afterwards. She was lactose intolerant meaning she couldn't have dairy without it hurting her stomach and making her sick. Which brings me to the story. It was a Friday morning and our parents had went on a honeymoon, since they never had one back when they first gotten married. I made me and my sister some cereal for breakfast before we would take off for school. “Goodmorning Jack.” She greeted me with a smile and a little hand wave as she walked into the kitchen in her pajamas but make-up already done. “Hey Alana. I made us breakfast.” I said turning around and putting the two bowls on the table. “Ugh. Cereal Jack? Really? You know I can't have dairy.” She says in a disappointed but also annoyed tone. “Well my bad but I already made it so just take some medicine with you and take it when THE DIARRHEA HITS!!” I say in a old movie trailer voice trailing off with a slight laugh. “It's not a bit funny Jack. I'm going to eat it but if I get sick it's your fault.” She says finally agreeing with the fact that it's already made and ready. I just roll my eyes at the fact that she makes a big deal out of everything. We finish eating and gear up for school. “By the way Alana, don't forget we have track practice today after school so come here not home.” She just yells yeah yeah back and keeps on towards the bus stop. As she walks I watch her beautiful big butt bounce around in her gray leggings. I'll admit my sister made me a little hard right then but that's gross so I completely ignore it. So as the day goes on I don't think of my sister or the milk she consumed earlier that day. I just did my work for school awaiting track.
So eventually track rolls around and I'm ready to run. I walk into the locker room and switch from my cargo shorts to my track shorts and smell something truly fowl.
PPPHHHHFFFFFGGGHHH!!!!!
A huge fart echoed throughout the locker room followed by a light splash. I, being an idiot, follow the horrid stench to the bathroom where I see my sister's shoes under the stall. “My God Alana! That's terrible!” I scream pinching my nose. “I- PHHGGGGFFHH!!- know! It's the cereal you gave me it had milk and I can't have dairy!” She screams from within the stall. “Okay we'll try to finish up track starts in 10 minutes.” I say as I leave the bathroom. I walk through the locker room and fieldhouse and go out to the football field and track. I set up my hurdles and do my stretches. Me, along with the other boys who do hurdles, began running the hurdles the way we always do. Soon my sister was out there running her mile or whatever in a tight pair of light blue yoga pants. As she ran past I must say, Goddamn that ass. It bounced just perfect and looked absolutely amazing on her slim body. As she ran past the second time though. Each step you could hear- PBBBFFFGGHHH!!!!! Sounded like she was shitting her pants. It truly was horrific. We finished up with practice and I met back up with my sister at home. “My god those were terrible!” I tell her as soon as we get home. “I know. Thing is I still have a lot of gas still up there I'm holding in for later.” She replies with a little smile. “What do you mean later?” I ask curious. “You'll see.” She says walking off. I just shrug and don't think about it again. I go off to my room. I shut the door behind me and pull up some porn on my phone. I pull out my 6 inch hard cock and begin pumping it along to the blowjob porn. “Oh fuck yes..” I whisper to myself. Right as I'm climaxing I hear a snap of a camera. “What the Fuck!??” I yell looking up to see my sister standing over my bed with a camera. “Jacks been a naughty boy hasn't he?” My sister says in a mocking tone. I yank my pants up and go to grab the camera in her hands. She pulls it out of my arms length. “No no no. You don't get to delete it. You'll have to do somethings for me.” The fuck? “Quit playing around Alana and give me the fucking camera.” I say harshly. “I'll post it on Facebook if you don't fucking stop.” She declares giving me a stern look. “No, no, no! I'll do anything just don't do that!” I beg shaking my head vigorously. “Anything?” She asks tilting her head to a certain angle. “Anything.” I confirm. “Okay. Fine, you're going to be my personal butt slave. Not will you just eat my ass and sniff it but anything and everything that comes out of it too. If you don't then everyone will see you jerking off.” I shake my head. No way this is really happening. “So let's get things started. Position one, this will be one for sniffing.” She lays on her stomach and let's her ass look so big and bubbly popping out in her gray leggings. “Get your face in between my asscheeks with your nose in as close to my asshole as possible.” She commands. I'm in no position to argue so I lay down on the bed too sticking my face into her butt and getting as deep as I can. I had always acknowledged the size and greatness of her rear-end but when you're this close it's a lot bigger. I breathe in and out through my nose and the smell is awful. It smells like she ate something bad. Oh wait. She did. This isn't going to be good at all for me. After a couple minutes I hear her stomach rumble and her grab her side. “Okay first fart of the weekend coming up!” She says in an enthusiastic tone.
I prepare myself for what awaits inside her asshole.
-PPHHHHGGGRRROOOFFFGGHB!!!!!
A huge 5 second brassy fart erupts from her big behind sending a smell I'll never forget up my nose. You couldn't tell if she ate something bad or ate something from the side of the road that was killed two weeks ago. It was horrid. “Hahahahaha omg I actually just did that.” She says laughing like an idiot. “ get up.” She commands. I stand up as she sits up and pulls her pants down revealing a nice little thong covering her pink asshole. “Alright you like porn and you like ass. Let's see if you like my ass you stupid fucker.” She says through gritted teeth. She starts grinding up and down on my face making me smell her raunchy behind. She gets in the position she was previously in and I do as well. I could feel her asshole touch my nose through her thong. “Three.” Her stomach makes a gut wrenching sound. “Two.” She slightly moves pushing her ass in my face even more. “Three!” -GGRRBBHHFFFPG!!! Another massive 4 second long fart exits her tight asshole spraying my face with her assgas. The heat within her ass was getting super hot and her ass was beginning to sweat like crazy. “Oh my God I'm so fucking horny. Hey bro you want to eat my ass and my nasty farts? Not like you have much of a choice.” She sits back up and slowly slides down her thong revealing her natural big tan ass. Within that ass you could see a pretty pink wrinkled hole awaiting for my nose and tongue to massage it as it pushes out sulfuric gases. Instead of going back to the same position she stays on all fours making her ass more wider and open. I crawl in and bring my nose to her asshole. She bounces around a little making my nose slide further and further into her asshole due to the sweat. After around 13 bounces she lets loose another huge fart. PPHHHHGGGRRROOOFFFGGBBRR!!!! This one was the biggest one so far! It mixed with the sweat, the ass juices and the humidity made it smell absolutely incredible. But not in the good way I legitimately thought I was going to puke from within her ass. “Lick it.” She commands. I take my time taking my tongue out of my mouth. I started down where her pussy ended and locked up her crack making a ring around her asshole. “Oh fuck yeah keep going.” I forcefully attempt to shove it in her asshole. I get a small amount in there and begin licking around making circles around the inside. I could feel her pushing another fart out of her asshole.
BBBBBBBRRRRRRRTTTTTTPPPPPGGGRRRR!!!!! She rips the the biggest fart of the night right on my tongue as I was eating her ass. It was a wet, slimy, sloppy fart that sprayed ass juice all over my face and my tongue. I keep licking though, attempting to ignore the sewage and rotten egg smell it left behind.”okay we’re done for now. I'll be back in an hour.” She says leaving the room, leaving me mesmerized and smelling like pure shit.

PART 2

I laid there nearly paralyzed. Did that really just happen?? No way that was real I must have been dreaming. No that can't be right either why would I dream of my sister? Especially of her ass? Actually eating her ass wasn't that bad until she farted. I would do that if she just asked me too at this point. I laid there and thought about for nearly an hour before passing out on my bed.
“Wake up Jack.” I hear my sisters taunting voice from close by I slowly open my heavy eyes to see my sister. She was wearing a backwards flat bill hat and a black tank top. The more my vision came back to me I could also see she was wearing tight joggers and I could see the top of the pink thong from earlier. I attempted to rub my eyes only to find my hands cuffed together lying on my stomach. “Hey brother. I brought a friend of mine along for round two.” I look over and see Alana's friend Kirsten. She almost instantly gave me an erection. She was 5’6 paler skin with dirty blonde hair. She had a perfect little nose and ruby red lipstick on. Her Breast were really good sized for her age and don't even get me started on her ass. It's absolutely gorgeous every bit of it. She was wearing a pink sports bra with the Nike sign in it and a tight pair of yoga pants. My dick jumped a little bit at the sight of her. “Me and her wanted to have some fun with you.” Explains Alana. Kirsten slides her hand up and down my crotch area. “Yes we do.” She says in a seductive tone, licking her lips directly following. “See I told Kirsten about finding you watching porn and jacking off and how I could do anything I want to you now and, she got so horny at just the thought of you and doing anything she desires to you. She pretty much begged me to let her come along.” My sister begins to take off her joggers revealing the thong. She crawls on top of me and spreads her cheeks about an inch away from my face making her asshole clearly visible even through her thong. “Oh and btw we had Mexican. Teehee.” She sits her big beautiful ass down on my face and wiggles around just a little bit. “There's the spot.” She says right when my nose is in full position up against her tiny hole. Her thong was soaking wet from sweat. I'm going to guess from what they were wearing they went for a run or something. I felt her hole tighten and then release with a grunt.
BRRRRRRRTTTTTT!!!
A four second fart explodes out of her rear end and directly on my nose forcing me to sniff the horrid gas.”do you like that big bro? Getting farted in by your little sister? It's fucking degrading isn't it? Too fucking bad.” She stood fully up towering over me. She slowly pulls her thong down and slowly sits back down. “Lick my asshole.” I don't do anything though just to see what she does. “Lick my asshole before I shit in your mouth mother fucker.” She goes on. I still do nothing. “I have to shit super bad. You have three seconds to start eating my ass or I'm going to shit right here I swear to God.” She's getting angry at this point. “3.” I sit there motionless. “2.” Still nothing. “1.” I put my tongue to the crinkled asshole just slightly then- FFLLRRGGRRUUPPLL!!!!!
A massive wet fart escaped her asshole all over my tongue spraying my face with liquid shit and ass juices. “Keep licking. Don't say I didn't warn you.” I lick her asshole tasting the sweat, the juices, the shit right off her disgusting hole. “I'll make this better for you.” I hear Kirsten say as my pants get pulled down past my knees. My dick immediately gets erect. I feel Kirsten's cold hand wrap around my hot 6 inch dick with such gracefulness. She begins pumping it just right giving me the feeling of a lifetime. I almost forget to lick the asshole that's residing on my face. So I'm getting a handjob from the girl of my dreams while getting farted on by my sister as I eat her ass. What a day it was. “Oh god here it comes!” Alana screams from on top of me as an absolute huge fart escapes her ass. FFFFLLLLLLRRRRTTTPPGGGLLSS!!!!
There is no proper way to type this fart out. More liquid shit flies out of her behind as this sloppy wet shart explodes on my face, my tongue and in my mouth. I keep licking though and get it all up. The taste is real bitter and salty. “I have to go shit right now!” Alana screams as she gets up and runs to the bathroom. I look over at Kirsten still massaging my dick. “now that we’re alone let me show you what I plan to do.” She says so seductively it sends shivers down my spine. She crawls between my legs and holds my cock up to her face. She licks the very tip of it. I lean back. “Oh yes..” Is all I can get out. “You like that?” She says in the same tone as earlier. She circles my dick with her tongue and opens her mouth. She slowly puts the head in her mouth wrapping her lips around it. She goes down so slowly making it feel so good. When she reaches the base she goes back up just as slowly. She's doing everything right. She'd been going for around ten minutes and she felt my balls tighten up. “Kirsten, I'm about to cum.” This makes her go crazy fast and the warm white liquid exits my dick into her warm mouth she swallows every bit of it and then some. I look over to see Alana back in the room.
