The Bet
by Billyzen

On a week end, Rachel and her brother are home alone... "bet" on what could happen...

"Where is the money that mom lets us?" ask Rachel.
"I thought you could pay in advance".
"And why do i have to pay with my pocket money for our meal? Mom had given us enough to buy food during her absence"
"yeah i know, i know but i had bet it with Ben."
"You do what !!!" screamed Rachel.
- I bet it on the playoff game Jets vs Steelers. If the jets wins and i think they will, i will double up my money, give back the half mom has given to you to buy foods and keep the other part for me. Easy no ? Yeap i 'm proud of myself.
- I think it's a little too easy for you. Rachel tells him.
- Let's make a bet us too. If the Jets win you pay me back plus the right to fart in your nose 3 times, after all i pay in advance as you say. But if they loose, you couldn't pay me back so you will be my fart slave for a clock turn.
- Wha da ya mean a clock turn asked Matthew, one hour?
- Ho no, my dear, round clock for me is 24 hours.
- NO way, you know what that mean said Matthew firmly.
- Well Matt in this case, mom will know for your bet and maybe ....... the E you got in Math and the vase you broke last month.
Matt was in shock and quickly reply
- I don't care, enough of your farts for me. Who do you think you are, it's stink too much when you fart. I know that you have not told mom for the vase to keep it for a better occasion.
- As you wish said Rachel, then i will said her too that i caught you smoking in the loft.
- But i never smoke interrupt Matthew .
- I know that but who do you think she will believe? Me or you. In my mind you have no chance and maybe i could add this was no cigarettes you smoke but drugs, this will be enough.
Rachel have made all she could on that one and this was too much for the little kid that reply only ...
- Rachel you disgust me you know that" Matthew put his head down and finally add "it 's OK for me".
Rachel knows that she could have easily overpowered her brother to make him smell her farts, he was so weak, but this time she wanted something other, she really want him to be obliged to inhale her gas and she have ideas of positions to fart in his nose.

Matthew know how her sis gas was, he have been gassed under her butt a million times since he was younger but no matter what he could say, she could wrestle him and do what she want. The truth was that this time, she want to oblige him to smell her farts without fighting and it scares him a little. Hopefully he had trust in his favourite team, Las Vegas bookmakers give NY a 7 lead for the game. The Jets on that day don't know they play not only for a championship spot but also for the safe of a little boy nose somewhere in USA.
Rachel didn't respect the rules thought Matt so he got to do the same thing and he try to reflect how he could manage to escape her farts just in case the Jets lost their game.
- Ok then let's go to the supermarket to buy food and dairies for me and you. When does the game begin she asked him.
- This afternoon at 14pm respond Matthew. Wait a second i got to go somewhere he told her.
She see him go to the toilet and discreetly follow him, she knew he had a bad habit, he never close the door from inside. Once he was trousers down making his affairs she open the door slightly, passed her ass and fart a loud and long one Prrroooooooooooouuuuuuuuuuuuuuuuuuuutttttttttttttt. "Enjoy that" she said and she close the door and hold it for a minute.
- Ok now you may have breathe all my fart, you are free to go. she mocked him. Take that like a sort of training for you.
Rachel and her bro went to the corner supermarket. Once inside, two boys around Matt's age start to follow Rachel staring hard at her butt openly. She effectively had a good one and perfectly knows it. She wore only tight pants that set off her ass. She smile at the beginning but after 20 minutes of the pursue almost 2 meters behind her always looking hard at her buns smoothly moving has she walk, she start to get annoyed by those pre puberty kids and headed to the sports-wear aisle when she felt a good pressure in her lower intestines. At least it had come, she was waiting for that for 10 minutes and now she will give them a good reason to stop their hunt.
She stopped pretend to search something on the lower shelves and bend her butt. She heard them giggling in her back. They must have a nice sight of her ass now.
"Take that" she thought and drop a huge SBD then another and another, the kids get hit by the smell of the first while she released the third one. The stench was killing and the two boys look at each other with a real disgust face, then they realise that was Rachel because she has turn to them and smile widely.
- Oh boy that was a good one she said, i think i got another one to spare. Why don't you lay on your backs so i can squat on your faces to let you smell them from the source?
The two kids stay in shock then go their ways running avoiding to cross Rachel stinky field. She laugh softly proud of herself. She had given them a good lesson. She continue to walk out of the department as if nothing. She finally found some ice cream, coconut was her favourite and she know this kind of ice cream was all she need. She took 2 ice cream trays and get back to see her bro. She went to the checkout point where she met back with him. He was a little kid with nothing particular, just the average little kid with his T-shirt of the jets and a non stop barking mouth, always saying "yeap, cool, great, Waaazzaaaaaa, he was pushing his hamper waiting in the queue up.
- Hey sis i took some chocolate biscuits for you and me, is that Ok ?"
Rachel looks at him
- You know perfectly well i don't like chocolate, but take your stupid biscuits, you will pay them to me later.
The kid ask her
- And where are those boys that chase you down the sports section? They must have a big crush on you.
To that she respond with a grin, the kind of grin she made when she fart on him saying
- Oh i find a way to shake them off, you better believe they will never come to see my ass nearer again.
And she give him an evil smile. Matthew 's face turn green and he lost his own.

They arrived at home, Matthew with his arms full of bags and Rachel hands free. When they were on the steps Rachel head to the door and step in front of her brother, she have an idea and of course a big fart waiting for release in her pants.
- Have you heard that? she asked him.
- Heard what? he respond with bags weighing a ton in his arms.
- That, she respond farting a loud one Brrraaaappppppttttt pointing her ass in his head direction and not so far from it.
He smell it and cough a little then start to breathe through his mouth to avoid the stench.
- I think this is a bad omen for the Jets game if my farts are coming hard like that
said Rachel, in a few hours i will regale myself farting in your nose. She continue to laugh while she enter the kitchen and start to range the supplies.
Rachel and Matthew watch the game on TV and Rachel finish all her coco ice cream. With her intolerance to lactose, this will bring a good treatment for her brother.
- Did it bother you if i alter my digest process? She said having big spoon of ice cream.
She was not a Jets fan and either a football fan but this time, she was hanging on each touchdown the opposite team scored.
She retain all her gas to built an enormous pressure in her belly and as the game go on and on the Jets seem to be in a bad day. The final play was shot and Matthew look down, he have lost everything, he got to pay now for the money he play with. Her sister must be full of her killer rotten cabbage gas. This is going to be mortal.
- Come on Matt, you know you have loose and now you got to breathe.
She headed Matt to her bedroom, but as soon as they passed in front of Matt's room, he run into it and close the door with a "wham".
- Poor little bro, do you think i am braindead told Rachel. You really think i will let your key on the door so you can shut yourself in.
She push hard on the door and the weight of Matt was not enough to stop her.
- Now crawl to my bedroom if you don't want me to tie you down, as i say i want you to be agreeable with my farts. I don't want to overpower you, but if you resist just one more time, i will beat you and fart on your face during all week end and when the parents will be back home, mom will know everything plus a little more of my imagination. So don't think you can escape.
Matt was trapped and he know too well what is going to happen. Once they arrived in Rachel 's bedroom, she blind him with a duster and quickly passed old plastic handcuffs on his wrists. She has keep them from Halloween when she was disguised in prisoner. He was now at her mercy and this give her a flow of pleasure that pushes shivers on her back. She have her black spandex tight short really moulding her crack so his nose could go very far in her butt.
- Lay down on your back and let the show begin she said.
He did as he have been talked to and wait. She went to her desk and pointed her webcam to where he was lying put up the microphone on her ass just up her crack and tuned the media player to have the better sound and image possible. She was giggling madly and Matt seem to dislike the treat.
- Wait honey, i'm coming she said.
She stand in front of her brother that couldn't see her and then go down with her ass on is face moving smoothly, she put her ass on his nose the better way she feel as he inspire more and more loudly.
- Now the rules are simple, if you try to breathe through your mouth, i will gag you and things will go bad for you. Instead if you breathe deep with your nose, i will let you some air sometimes. Rachel feel the first barrage coming in her butt, she giggled and hold his head right putting the tip of his nose in the right way facing her asshole.

- Open wide your nostrils she said as if he could close them at will.
And she push a nice broooping one, long and loud sounding like a PRRRRRRRRRRR-PPP-PPPP.
- Waoh that 's good.
Matthew moan under her butt, he have took deep breath in his nose and didn't try to cheat with is mouth.
- You are a good boy said Rachel.
She strained again and Frrrrraaaaappppppppprrrrtttttttt made another long one, again she heard him breathe her fumes. She thought those big ones must have inflate is nostrils when passing in. Vibrations on his cheeks again as Broooiiiiiiffffffffffprrrrr
- Oh my god, whooooo yooooooo whoooo, this one squeak on your face. Oh that's soooo good Matt.
Matthew couldn't breathe anymore, the stench was so bad he almost threw up. The only thing she let him breathe was her gas, a kind of mix of shit, cheese and some other dead smells. The last thing that was in his mind was a question. Why did his sister love to fart in his nose? What did she feel good in that?
He have no response but only succeed to escape a little to said her sister.
- Rachel, i can't breathe, you 're going to kill me.
- No, you see you can talk, you are far away from death. Just shut up and breathe my farts.
With that she drop a long one, she didn't know she could fart so long. It must have last 6 or 7 seconds, she felt the nose of her bro trying to stop the gas to escape from her anus. The only result was a better flushing of warm air in his nostrils. His lungs start to burn from inside and he may have not more air in them. She start to laugh loud and fart more.
Poor Matthew have no air to breathe that was not tainted by Rachel 's gas. She have farted 6 times in a short period of time, she was on a very gassy day and she have him as her fart slave for the entire 24 hours coming.
She readjust her position and wait for some more farts. She look to herself in a mirror and said to the reflection. "You're a bad girl!!" She laugh again and let her brother breathe a little because she have no farts in store now, those ones she have made before were huge and it may take some times to built again.
She stop the recording on her computer and headed to the kitchen to drink some milk. She didn't like milk but the result will be far worst for her brother Matthew.
Passing the door she said to her brother. "Stay where you are, i will be back soon."

Matthew was waiting, it was now almost 15 minutes he lied on the floor of her sister's bedroom. The first barrage of thunder farts she gave him put is mind in a cell. He is now like a zombie only conscious of his sadness and the terrible smell he still got in his nose.
He heard her coming, his eyes still covered by the duster.
- I hope you got your second wind? She ask giggling. What did you think of my last farts?
- They were terrible, stunk so bad for me in fact, Rachel you must stop or i will be unable to retain and vomit on you.
- You know what will happen if you vomit Matthew, i assure you, you better find a way to retain. And you are not the one who could tell me to stop, understand that.
With that she sit again in her favourite position. Matt feel her flesh and skin, she was bare ass.
- Ho no, my god he said. No, not bare ass.
- Shut up Matt, listen closely it's coming.
She put her head back in a strain concentration and from her ass gushed a long growling fart, BROOOOOUUUUUUUUFFFFFFPPPPPPPRRRRRRRTTTTTT she feel it going directly inside her brother's nose. The stench of that one must be terrible and she was sure of that but if Matt do his job correctly, she may not breath it. She imagine the look of horror he must have breathing this fart. She giggled loud and look straight at the web cam while she feel another one coming, she said "hey brother, you 're gonna love this stinky one" and she push 3 times on his belly making him expulse the last fart he have just finish to digest. She felt air rushing on her buns as he expulse. Then she sat back on his nose really cutting all of his air and he quickly start to stir and squirm in panic. She took her time knowing that he could retain his breath some more seconds. When he was at the rift of unconsciousness, she freed his nose just a little to let him breathe and as he start, she let go a big blowing fart PRRRRRUUUUUUUUUUFFFFFFFFFFT this one could shut off a candle.
Just to be sure he will not waste this huge one, she press her hands on his mouth to force it close. An inhuman smell of eggs, cheese, cabbage, shit, start to flow up to her head and she exploded in laughter knowing that it must be ten times worse under her sweet ring.
She was very proud of the last one sure this was just the beginning and the 2 huge meal of coco ice cream have not given their best shot right now.
- Hey, bro are you awake? she barked at him sure that he will not respond.
He was now half asleep with only a difficult breath.
- It 's so nice you continue to breath through your nose Matthew.
She prepare a good one for him, bend on a cheek and reward him with a good SBD with an mayor D just to be sure he was in dreamland. He was now obviously KO but she continue to fart on him making big ones and soft ones. The stench has filled her bedroom and finally embarrass her so she released his head from the hold of her ankles that form her gas chamber. His head roll on the side completely asleep.
She start to get a little annoyed and let him free. She went to her desk and stop again the recording.
- I have so much gas today i can make an entire fart movie with my brother as a tortured smeller.

Matthew awoken his hands still tied in his back eyes free, he was in his bed and he see Rachel naked with only a T shirt standing above him and looking at him.
- Ha finally you awoke, it's more funny like that.
- No please Rachel, no, no, i will give you all my money, do all you want but no more farts please begged Matthew.
- Ho, your so sweet, but you don't have any money to give and the only thing i want is to gas you down. You squirm too much so i am sorry but you will be gagged.
She roll a piece of tape and shut is mouth before he could tell anything.
- Here, it's much better now.
She sit on the bed at his side and talk softly in his ears, she could smell the remnants of the farts that still engulfed his face. The smell sort of glued in his hair.
- I want you to know Matthew, i will now sit on your face and fart with your nose deep inside my butt crack, you will really gonna like it, you'll see. I have 23 hours to make you pass out the more times i can. This will be hard torture now and your nose will remember the smell of my farts ........ forever. My gas is now potent and all the ice cream i eat was asking for release, you should have pray to get a cold instead of bet your stupid money on that game. Ho ho here it comes ...
Rachel quickly mounted on the bed and straddled his face, she want to try an other position and sit on his head with him in her back. She was not used to that one but after all she got a lot of gas to spare and she will turn when she needed to. She feel her sphincter on his nose and bent back to put it the right way on Matthew's nasal passages. He seem to be so panicked she feel herself turning on it.
- My little speech seem to have is little effect on you, let's see if my gas will too.
A loud PPPPRRRRRRRRROOOOMMMMPPPPPPPP echoed from under her ass, she almost levitate for a second.
- Ho god, take it all in, that 's got to smell good, she said in a laugh. Have you said something Matthew? Ho no you better keep your breath for that one, PHHHRIIIIIIIIIIIIPPPPPPP made a dryer one expulse at high speed in his nose.
Matthew feel again his lungs filled with the pungent farts of his sister. She have placed her butt so that he could not get a single breath of air, in fact he survive breathing her farts. The stench was so bad, tears start to run on his cheeks and Rachel feels them on her own.
- Ho little baby is crying. You'd better stop .......... you need some air, what a coincidence, i need to fart she said and she give him some of her own belly air, a kind of air tainted with gaseous substances.
She turn to squat on his face rather than sitting on it and push the process with only big loud and windy farts. She was at her best, full of nasty gas. One of the more gassy day she ever had. She laugh hard at his face as he fall unconscious 2 more times in that position. Now he didn't squirm anymore, she asked to herself if he didn't start to like it a little.
Contrariwise, her own gas was really turning herself ill and she start to get oozy. How could he stand all the farts she put in his nose at close range was beyond Rachel.
She felt her bowels rumble and replace her sphincter at is right place.
- Matthew, hello, it's time she shout to awoke him and as he leave his sleep, she hold her cheeks apart and buried his nose in her ass to fart the biggest one of the day BRRRRRRRAAAAAAAAAPPPPPRRRP-PR-PR-PR-PPPPP. A long squeal emanated from her butt as she expulse a 6 seconds loud and stinky one.
- Maybe i can make a fart contest, i could win money with fart like this. Ho my god what a stench she said when she catch a whiff of the last.
She couldn't bare her own smell and that one was too hot, she stood up and leave the room.
Once in the kitchen she breathe fresh air and drink the other half of the bottle of milk.
- This is a good brand, i will told mom to buy that one only.
A luminous idea strike her, she felt her intestines rumble and rumble again, all the methane contain in her belly want to get out. She remember something she have read of a gassy girl putting a young boy under the cover when in mood to dominate. She got to do the same and gas her bro under the cover, like that she will not be annoyed by her own smell and could fart all night long on him under the cover.
She didn't feel she have to shit, everything she has eaten has mutated in gas, killer gas. Tonight will be tough for Matthew.

When she came back to the room, Matthew was awake and struggling on his handcuffs almost freeing one hand. The entire room was shrouded with the smell of the intense farting session that have just finish.
- Ho you try to escape, no, no she said.
And she quickly hold is free arm and push it under him while she straddled his face.
- I got to tie you better next time but now i have the other half of the bottle of milk that want some freedom like you. First, i will cooled your struggling, then when you will be in dreamland i will tie you for tonight session.
She press her sphincter on his nostrils just enough to let gas pass without smothering him. She took her T shirt and push it over his mouth.
- Now you will really breathe my farts, hey why are you holding your breath, you know it's dangerous. Come on breathe Matthew, anyway i could retain my farts longer than you with your breath.
Finally, Matthew explode in a breathing fury after 50 seconds holding it, he try to escape her hold and fight with all his strength but that was not enough, he had suffer a 3 hours non stop farting and have no more to put up a fight. When he finish his vainly struggle, Rachel place her feet behind his head and hold it straight up, then she told him.
- Ha you see, now you got to breathe, you will love the next episode, good night little brother.
She could feel his hardly breath on her undulating buns, she curved her back and look down at him, she could see his glazing eyes and the top of his nose buried in her ass crack, she strained unnnnhhhhh and FFFFFFRRRRRRRRRRRR, she farted a very long SBD that was perfectly atoned by Matthew 's nostrils, she heard nothing but the way Matthew try again to escape, it must have been a really Deadly one. She felt another one and another and another and give him the best farting action she could, he passed out after the third but to be sure, she give him two more methane shot directly in his mouth and pinching his nose to complete the humiliation.
He was now at her mercy and she freed him to search for something to tie him under the cover of his bed. She leave the cover and sheets to made the bed and tie him under by the hands to one of the upright of the bed, she then dutifully replace a piece of tape on his mouth, this time wrapping it around his head. Everything was fine so she place him in his bed and went down to watch TV before the show will start.
It was 8.30 PM and the info talks widely of the Jets lost.

The pressure was coming back hard and the mix of milk and coconut ice cream was on a real fight with her intestines.
It was almost 10 PM and the TV program was boring as usual. "it 's time to start the funnier of all now".
She went to Matthew's bedroom and find him struggling on his rope, his wrist a little red trying to escape.
- I am proud of my knots this time, you can't escape. Ok Matt bye bye she said to him waving her hand and covering him with the heavy cover he use in this cold January. I hope it 's not cold under, ha ha don't worry in a few minutes, it will be hot as a reactor.
She place herself in the bed and oriented her ass to his head only 4 or 5 inches from his nose.
- You will really feel my winds on your face like that. But please Matthew try to resist a little, it's no fun if you are always KO. Here we go, ungghhhhh PPRRRRROOOOOMMMMMPPPPFFFFF - PRRUUUFF waohhhh that was a good one, breathe, yes breathe Matt ha that's smell good no?
Matthew start to mumble and squirm under the covers. He got the entire effect of that fart right in his nose and the stench was absolutely inhuman. She have farted on his nose too many times for him to remember but those she made right now were a head above everything he smelled before. He was in his thought when she cut loose another one like a tuba bass POOOOOOMMMMMMPPPPPFFFFFFFF. Her winds again environ his head and with each breath he got to make he took a whiff of her pungent fumes, something like old cheese, eggs, cabbage and broccoli. She continue to fart at short interval so the bed was quickly filled with her smells. She laugh so hard above him he again explode in tears and continued to breathe her farts.

Rachel push her art to her best that night, never step out of the bed continuously farting for her brother's nose to smell. She feel no sleep and have so much fun she may had orgasm 5 or 6 times (in fact she lost count). Matthew passed out more than 10 time and finish the week end ill even after she release him as promise. He told to her the week after he always have her smell in his nose and Rachel keep to herself the "bet of the jets" and swear to Matthew to give him some farts next time she will have to relief.

The end
