Maddy The Gassy Sister
by LuMo187

My name is Charlie and the day my little sister was born, my life changed completely. Both my parents and I used to be an ordinary family, living in an ordinary house, doing ordinary things. But those times changed when my mother got pregnant again.
The night we came back from the hospital I realized that the attention I got on a daily basis disappeard for the benefit of our new family member 'Madison'. I hated her for that; a little alien coming on this earth just to drive a wedge between me and my beloved parents, at least that was what I felt.
When Madison turned three my mom and dad decided to register her to a kindergarten, due to the fact that both my parents worked, my dad as a fireman and my mother as a police officer; they met each other during an arson attack. While my sister went to the kindergarten I went to school, the second grade to be exact. Everything went normal until Madison turned four and the people in her kindergarten started to notice something odd about her.
On this fateful day when I came back from school early, my mother and my sister were both already at home. My mom told me that my sister doesn't feel very good and that they're gonna check that out at her docter. It was later that evening when I found out that my sister was diagnosed with lactose intolerence coupled with a severe case of chronic flatulance. Her caretakers send her home because she had a troublesome case of gas that disturbed all people within the building. Some parents even had to pick up their children because they began to feel sick of the smell; and all that because of too much cheese for breakfast. I found it funny at that moment, but little did I know that my sisters gases would soon control my life.
Fast forward eight years, Madison now 12 years of age and as annoying as a little girl can be. I was 16 and started to mind my own business, hanging around in my room all day playing video games and watching TV. It was saturday and I was up early so I could enjoy some time alone, but it seems like some higher power told my brat of a sister about my intentions because not even 30 minutes into my TV session Maddy knocked on my door.

"Hey Charlie, I can't sleep anymore. Can I come in?" her cute innocent voice called to me, and before I could even tell her to go away she already stood in my room closing the door behind her. My sister pretty short and slim but already showed some development in her hip area just like my mom. She had light blonde hair, bound into shoulder length twintails. Her hair and her big hazel coloured eyes made her look pretty cute, I had to admit that. But that didn't change the fact that her constant farting could kill every positive thought about her. I was sitting on my couch rolled up in my blanket due to it being pretty cold in my room. Obviously the same thing my sister thought cause she quickly jumped on my couch next to me and forced herself under my blanket, cuddling against me.

"Could you, like, move a bit? You haven't even brushed your teeth yet." I said annoyed like always. But Maddy just shrugged her shoulders and giggled into my left ear.
"All you can smell is my cheese sandwich and the milk I just had, so stop nagging." she laughed while patting her stomach. I knew what those ingredients did to her body and I couldn't wait to experience the byeffects of this breakfast, sarcastically saying.

"God, Maddy, you know you can't eat this stuff. It turns you into a freaking gas machine!"
"But I love cheese and milk! And mom and dad say I can eat it on the weekends." she smiled before pressing herself even closer to my side.

She was right though. Our parents allow her to eat cheese an weekends because she loves it so much and they don't want to disappoint their little princess, as long as she stays in her or my room. I tried to explain to them that I'm not okay with her releasing her gaseous shit in my room but they just respond with 'Be a good brother' or 'Siblings shouldn't care about stuff like that'. So the scenario I was in wasn't something new; more likely it was common on weekends like this.
We both sat there under my blanket for about 15 minutes when Maddy's stomach roared through the house. She immediately smiled at my face, knowing what the gurgling sound meant.

"Please Maddy, please hold it in, just for once." I begged fearing her cheese and milk aftermath. But the brat had other plans.
"You know my stomach hurts when I hold it in Charlie. I will just release it under the blanket, you won't even smell a thing." She giggled again before her mouth opened and she looked at the ceiling as if she mentally transported to Narnia or who knows what.

"pppppppppppppppppppppppppppppppppppppppppppppppppppfffffffffffffffffffffffffffffffffffff
ffffffffffffffffffffffffffffffffffffffffffftttttttttttttttttttttttttttttttttttttttttttttt
tttttttttttttttttttttttttttttttttttt!"

I didn't understand the sight in front of my eyes until i felt the melting warmth under the blanket. After about 15 seconds her open mouth turned into a big grin.

"Aaaaaah, that's way better. And so warm hahaha." She began laughing and wiggling her bottom on my couch.
"Oh god! Maddy! That's disgusting. If you have to fart then go to your own room god damn it!" I shouted out, my nose wrinkling while catching a whiff of her recent SBD.
"No can do. I like it her better, and I wanne watch TV with you." she responded, laying her head on my left shoulder and spreading her legs to the far left end of the couch, her toes pointing out under the blanket.

I could feel sweat building on my skin because of the heat around us. But even that was tons better that the eggy stench flowing around the room. At that point I didn't wanne know how the air under the blanket must be. It must be like sitting in a sauna full of rotten eggs and pure shit. My thoughts cut off when I heard the next stream of gas firing out of my sisters round little butt, the loudest silent but deadly I've ever heard.

"pppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppphhhhhhhhhhhhhhhhh
hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhffffffffffffffffffffffffff
fffffftttttttttttttt!"

It went on for 18 seconds before stopping, spreading even more heat and stink around us.

"Hehehe, they're all silent today. But the silent ones are the smelliest, right charlie?" she asked before grabbing the blanket and putting it over my head within a second. I immediately gagged and coughed from the revolting smell. You would think I got used to it over the years, but that never happened. I still couldn't believe a human being could create such toxicity. Not even dad after a whole bowl of chili with extra beans came close to Madison after just one glass of milk and a cheese sandwich. I couldn't take it anymore and pushed my head back up from under the hell like blanket.

"What the fuck?! Are you serious? Ugh! Why the fuck did you do that Maddy?!" I was roared out, pure anger on my face and tears streaming down my cheeks.
"Hahahaha, stop crying I know you love my farts, brother." She laughed, sticking out her tongue.
"Shut up, you know too well how much I hate your stink. For gods sake, can't you just leave me alone for once? I don't deserve this shit!" I stood up from the couch making sure that my blanket didnt leave the surface too much. I was pissed and sat down at my desk, turning on my laptop.

"Oh come on. Don't be mad. You can't leave me alone here. I need my brother to share my warm fumes with." she giggled before yet again her stomach gurgled loudly.
"I don't care anymore. If you have to fart then do it over there! I will stay here, and don't your dare stand up!" I told her, searching for an interesting video on Youtube.
Maddy just looked at me offended and started to let out some more farts.

"PPPPPPPPPHHHHHHHHHHHHOOOOOOOOOOOOORRRRRRRRRRRTTTTTTTTT!" "BBBBBBBBBBRRRRRRRAAAAAAAAAMMMMMMMFFFFFTTTTTTTT!" "PPPPPPPPPPPPPPPPPHHHHHHHHHHHHHHHHHHHHOOOOOOOOOOOOOOOOORRRRRRRRRRRRTTTTTTTTTTTTTTTTTTTTT!"

She let out three more farts; the first one going on for six seconds, the second one for four seconds and the third one for 11 seconds. All of them were much louder than her previous ones, nearly shaking my couch with their bassy and bubbly tone. I knew those kinds of farts. This sound indicated her pushing them out by force. And she usually did that when she was pissed.

"God please, not her angry farts..." I thought to myself. I turned around to see her grumpy face glued to the TV screen.
"Maddy, come on, you have to understand how annoying your farting gets. And I can't stand it anymore. I know you're my sister and I know you just want to spend time with me, but at least stop eating dairy stuff then, okay?" I expected some form of ignoring or insulting but weirdly she just looked at me and began to smile ear to ear. Was she farting again? Did I have something in my face? Or did she really finally get my point? All those ideas shuttered when she said the following:

"What do you think mom and dad would say if they knew that you smoke?"

I was frozen right on the spot. I started smoking weed with a friend of mine a few weeks ago. She probably didn't understand that it was cannabis and just assumed it were cigarettes, but she indeed caught me last sunday night at the window of my room. I could convince her not to say anything to our parents, and I was stupid enough to just believe that. dropped to my knees and started to beg her.

"Please Maddy, please. Mom and dad would kill me if they knew. Please, I'm sorry, okay? I didn't mean to insult you or anything. And you can eat as much cheese as you want, okay? I promise I wont say anything about that anymore, but dont tell them, Maddy." She seemed to get more excited than before.

"Hehe, I like it how you bow down for me. But that's not enough, big brother. Let's make a deal. I won't tell them anything about the smoking if you agree to become my slave for one week."
"Your slave? Are you kidding me? Fuck off Maddy!"
"Okay than I guess I should go check if mom and dad are finally awake, don't you think?"
"No, no, no. Please wait, Maddy... I..." I couldn't believe it but my little sister did have the advantage. I was at her mercy. "Alright, you won. I will become your 'slave' if you promise to keep quiet..."

She jumped up out of joy, releasing all the stink from under the blanket, turning my room into nothing less than a gas chamber. I gagged and pulled my shirt over my nose to stop the smell from burning my nostrils. Something that Maddy didn't seem to appreciate.

"Uh uh uh. Put your shirt back down. As my slave you have to accept my smell. No matter how bad it is, hehehe." She underlined that statement by lifting her right leg and forcing out another fart.

"BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR
RRRRRRRRRRRRRAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAMMMMMMMMMMMMMMMMMMMMMMMMMMMMM
MMMMMMMMMMMMMMMMMMMMMMMMMMFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
FFFFTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTT!"

Her longest fart today to this point with a length of over 30 seconds. 30 seconds of bubbly and extremely wet fart gas. From the sound of it I wouldn't have been surprised if she actually shat herself, not the first time that that happened. when the first wave of her gas reached my nose I almost fainted. The smell was worse than all her previous farts combined. I jumped up to quickly open my window, but my beloved sister crushed my plans and my hope for fresh air.

"Don't even think about opening that window! I like the smell and so should you. And it's just the first day of your week of being my slave. It's going to get much worse, believe me. I'm planning to eat lots of cheese this week, and drink lots of milk. Maybe you can buy me some beans on monday to add to the mix. Oh, and you won't say a word to mom and dad about that of course. Hehehe I'm so excited! You're gonna do everything I tell you to do. Clean my room, clean my shoes, especially my soccer shoes, they need it the most. Oh oh, and I could sleep in your bed, that way I don't have to head to mom and dad's bed in the middle of the night when I can' sleep."

All of this sounded like pure hell but as sad as it was, I knew I had no other choice than to play along. God have mercy, just the thought of sharing a bed with my sister terrified me. I remember one night sharing a tent with her on a camping trip. After a bowl of chili she farted the whole night, uncontrollably. I think at some point I even passed out. "This is going to be the worst week of my life. I know it..."

"Alright slavey, Go get my pink sneakers for me and bring me some bread. They are the perfect place for your breakfast. Oh and give me your pillow before you go, I need something to fart on. I can feel the big ones coming, hahahahaha."

And there I was, standing in the kitchen, looking for bread, the loud rumbling coming from my room disturbing the peace that I had hoped for all week.

"PPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPP
PPPPPPPPPPPPPPPPPPPPHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH
HHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOORRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR
RRRRTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTT!"

Over the next years more and more occasions like this occurred, which changed the relationship between me and my sister immensely. When I turned 20 I was already the slave of my 16 year old, beautiful but dominant sister. I granted her every wish and accepted the fact that she and her monstrous farts control my life. Probably forever.
