It was summertime, Aaron just finished his last year of highschool, along with his sister, Katrina, summer break had just officially started, Aaron came back home early while his sister went out with her friends for a bit coming back home late. Aaron was a bit of a loser, he did not really have any friends, all he did when he got back home was just go in a cycle of being on his phone and playing video games.

His sister, Katrina wasn't very popular but she was known for being very attractive and unlike her brother, she did have friends. Katrina is 5’5, 170 lbs, crimson red wavy hair that stretches down to the middle of her back, a big round ass that catches the many eyes of guys who can’t control themselves, perky and cute boobs that can catch many stares, and eyes as green as an emerald, she was more on the chubby side but most could say that she is chubby in the right places.

Aaron on the other hand, is 5’8, 150 lbs, orange-red hair, has a decent body from working out, Aaron is also a somewhat decent looking person, it is just both his personality and social skills he has that just makes him very unattractive as a person.

Katrina arrived back home later at 7:00 PM right at dinnertime, she entered seeing just Aaron at the dining table, she just arrived right on time for dinner. Their parents went on a trip to Hawaii right as their children’s summer break started, so Aaron and Katrina got the house for a week to themselves.

Katrina walked up to the dining table and spoke to Aaron, “Sup dork, what’s for dinner?” Katrina says with a careless voice.

Aaron takes his attention off from his food to his sister, she was very sweaty, but man she looked so attractive, if only she wasn’t such a bully to him.

“I cooked up some of that frozen coconut shrimp. There’s some left if you want it.” Aaron answered her question.

Katrina looked at the stove and saw a cookie sheet halfway filled with coconut shrimp. “Make me a plate, would you?”

“Make one yourself.” Aaron replied.

“Oh, so that’s how it’s gonna be?” Katrina stated as she approached Aaron and grabbed his arm and yanked him out of her chair.

“What the fuck are you doing?!” Aaron yelled.

“When I asked you to make me a plate, it wasn’t a request.” Katrina said as she sat on Aaron’s chest.

He tried to push her off, but then she grabbed his arms.

“Get off of me, fatass!” Aaron yelled.

“Fatass, huh? You just made a BIG mistake.” Katrina said before she scooched up towards Aaron’s face, her shorts covered vagina was sitting on top of his chin. “Like the view, loser?”

“Oh my god, it smells like rotten fish!” Aaron yelled. “Didn’t you even bathe?”

“Shut up.” Katrina said before scooching even further so that her crotch was covering his mouth and nose. “By the way, I’m only “fat” in the right places, loser.”

Aaron screamed into Katrina’s crotch, even though her crotch was covered by her cargo shorts, the smell of Katrina’s unwashed vagina was beyond unpleasant.

Katrina remained for about 15 seconds before getting off of Aaron’s face and standing up. “You gonna make me a plate now?”

Aaron took in some heavy breaths before he replied. “Fuck… you.”

Katrina started unzipping her shorts. “I’m actually kinda glad you said that.” She then pulled down her shorts and kicked them off. “I get to really make you suffer.” She then walked towards Aaron until she was standing right over him before turning around.

“Katrina what are.... HHHFFFFMMMM!” Aaron tried to say before he was interrupted by Katrina sitting on his face. “HHHHHMMMMMMMFFFFFFF!”

“Like the smell of my bulbous butt, bro?” Katrina laid her legs on Aaron’s chest. “I didn’t wipe too well either, hope you don’t mind.”

Aaron was in absolute hell, little did he know how bad it was going to get.

Katrina then clutched her stomach before it gurgled. “Hey bro, need some air?” She then grunted before a massive trumpet sounding fart shot out of her ass.

PPPPPPPPPPFFFFFFFFFFFFFFPPPPPPPPPPPPPPPFFFFFFFFFFFFFFFF

“MMMMMMMMPPPPPPPPPPFFFFFFFFFFFFF!” Aaron screamed at the top of his lungs.

“Quit screaming, you little shit.” Katrina then started grinding her ass, rubbing the fart smell into her poor brother’s face. “It’s what you fucking deserve for not making me a plate.”

Aaron tapped Katrina’s left thigh and she raised herself up. “You gonna make me a plate now, bitch?”

Aaron nodded his head in response.

Katrina got off her brother and stood up. “Go make my plate, loser.”

Aaron got up and headed towards the cabinet where the plates were at all grabbed one. He then went to the shrimp and scooped a few pieces onto the plate with a spatula.

“Uh uh, I want the whole thing.” Katrina said.

Aaron proceeded to scoop more shrimp onto the plate until it contained all the shrimp that was on the cookie sheet. He then walked to the table and put the plate down.

Even though Aaron finally caved in to doing what his sister asked of him, sadistic Katrina was not through with him.

“Now… why don’t you start getting on your knees” Katrina said looking at him with an evil smirk.

Aaron was about to defy her, but he realized how much power she has over him. If he fought back he knew she was gonna make it worse on himself. So all he does is start slowly getting down on his knees in front of his evil sister.

Katrina looks down at her poor brother’s face, she finally has him wrapped around her finger. There are many thoughts going through her head about what she could do with her brother, but she wants to take it slowly before fully making him her servant

Katrina turned around and lowered her ass down onto his scared face while he was on his knees, she was basically gonna sit on him as if he were a chair.

Aaron put his hands on the ground behind his back onto the ground so he has more support to hold his sister’s weight. Despite that, however, her weight still put a lot of pressure on his neck.

“How’s it feel being my chair loser? I bet you feel so humiliated.” Katrina said before she started eating the shrimp. After finishing off about 3 pieces, she raised herself off Aaron’s face. “Go into the fridge and get me a soda.”

His sister was right, Aaron felt so humiliated, but he still did as he was told and stood up and walked towards the fridge, grabbing a lemon lime soda. He then walked back to the table before placing the soda next to his sister’s plate and got back into position.

Katrina sat back on her brother’s face and opened her soda before she took 4 pieces of shrimp and shoved them into her mouth and chewed on them like a rabid dog that hadn’t eaten in a few days, she then swallowed the shrimp and followed with a swig of soda. Aaron, meanwhile, was struggling just to not collapse.

“Get your nose ready, bro, I got some more air for you to breathe.” Katrina said.

PPPPPPFFFFFFFPPPPPPPPTTTTTTTTTTPPPPPPPPPFFFFFFFFFFFFFF

FFFFFFFFFFFFFPPPPPPPPPPPPPFFFFFFFFFFFFFPPPPPPPPPTTTTTTTTPPPPPPPPPPPPPPPP

“MMMMMMMMMMMMMMMMPPPPPPPPPPPPPPPPPPPFFFFFFFFFFFFFFFFFFFFFF!” Aaron screamed into his sister’s ass after she released 2 butt bombs up his nose, each one worse than the one she released earlier.

“Smell that shit, you fucking loser.” Katrina said. “You deserve to be my fart filter, you little bitch.” Katrina added to Aaron’s humiliation by rocking her ass back and forth, rubbing the scent of her farts into his tortured face. Katrina then stood up off of Aaron’s face and moved to the right. “I got a great idea.”

Aaron didn’t hear what Katrina said as he was too distracted by the relief of being free to breathe fresh air. Sure, it was tainted by the stench of his sister’s farts, but at least that stench wasn’t all he was breathing. However, in his state of relief, he was too distracted to see Katrina taking off her panties. He was giving his wake up call when she walked back in front of him and sat back down on his face, this time no panties to block his nose from touching her bare asshole.

Katrina grabbed the back of Aaron’s head and shoved it into her ass further until his nose slid into her asshole, giving her a sense of euphoria. “Yes, that feels amazing.”

Katrina was having the time of her life while Aaron was living a nightmare.

FFFFFFFFFFFFFFFFFFFPPPPPPPPPPPPPPPPPPPPPPPPPPPFFFFFFFFFFFFFFFFFF

“HHHHHHHHHHHMMMMMMMMMMMMMMMMMMPPPPPPPPPPPPPFFFFFFFFFFFFFFFFFFFFFFFF!” Aaron screamed into Katrina’s ass once again.

Katrina had let out another ass explosion, and it was worse than the previous 3 combined, though that may have been because there were no panties to shield off some of the scent on top of the fact that Aaron’s nose was right up his sister’s asshole.

“Quit screaming, it’s fucking annoying.” Katrina said before she devoured 3 pieces of shrimp.

Aaron could not help but scream, the stink was unbearable, and he was taking it up close. Unfortunately for him, this torment was only going to get worse from here on.

Katrina, with an evil smirk on her face has another idea to torment her brother. “Open your mouth wide, I want you to swallow all of my farts like the good bitch you are.”

Aaron’s eyes widened to the statement, there is no way he would open his mouth so his sis could fart in it. He was now pissed at how far Katrina is taking this.

“Fuck off im not doing that!” Adam yells a bit muffled underneath her bare ass.

Katrina gets off him and looks at Aaron with a clearly annoyed and angered expression, she starts to threaten him. “Yes you are because you know how much worse I can make this for you. How would you feel if I took some pictures of this and posted it for the whole school to see?” Katrina looked pissed and Aaron already knew she was serious,

Even though Aaron does not have a social life, he is not trying to make himself look like even more of a loser. He is for sure going to be bullied if any news of this spreads, basically posting a pic of this is going to cause collateral damage to Aaron’s life basically ruining it, he has to do what his sister wants, no matter how bad it may be.

Aaron after a while hesitantly starts opening his mouth but this doesn’t satisfy Katrina enough. “Open wider dumbass!”

Adam starts opening it a little bit wider but this still isn’t enough.

“Wider!!” Katrina yells and shows Aaron her phone to show that she has the power to ruin his life with it if she wanted to.

Aaron finally complies, opening his mouth as wide as he can, Katrina finally sits down to make sure her asshole is perfectly aligned with his open mouth.

The taste was beyond foul. Aaron had bad tastes in his mouth before, but his sister’s bare asshole made him want to die.

Katrina took 4 pieces of shrimp and shoved them into her mouth. “This shrimp is delicious, too bad you can’t have any, bro.”

SSSSSSPPPPPPPLLLLLLLLLLPPPPPPPPPPFFFFFFFFFFFFFFFFFF

Aaron retched at Katrina’s fart, it was more disgusting than he could ever imagine.

“You like that, bro?” Katrina asked. “I hope so, cause here comes more.”

PPPPPPPFFFFFFFFFFFFFPPPPPPPPTTTTTTTTSSSSSPPPPPPLLLLLLLPPPPPP

FFFFFFFFFFFTTTTTTTTTTTFFFFFFFFPPPPPPPPPPPPPPPPPP

SSSSSSSSSSSSSSSSSSLLLLLLLLLLLLLLLLLLLLLLLPPPPPPPPPPPPPPFFFFFFFFFFFFFFFFSSSSSSSSSSSSSSLLLLLLLLLLLLLLLLLPPPPPPPPPPPPPPPPPPP

Three farts, right into Aaron’s tortured mouth, each one worse than the last, each fart pumped air into his mouth puffing his cheeks, this was hell for Aaron. “This couldn’t possibly get any worse.” he thought.

“Uh oh, prepare yourself, loser, it’s about to get much worse.” Katrina warned.

Aaron panicked, Katrina’s farts were already the worst thing he had ever tasted. How could it possibly get worse for him? He was about to find out.

“Buckle up, brother, here it comes.” Katrina said before letting out a massive grunt followed by a solid mass that exited her asshole and entered Aaron’s mouth.

“HHHHHHHHHHHHHHHHHHHHHHHHHHHMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM
PPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF!” Aaron screamed at the top of his lungs.

Katrina only laughed at his muffled screams, enjoying how he was suffering under her, enjoying the fact she was using him like an actual toilet.

It was bad enough that his sister farted into his mouth, but now she had just let a turd into his mouth. It wasn’t a small turd either, it was large, as if from a large animal. The turd was so big that his mouth became too packed to hold it in, and rather than leak out of his mouth, the turd started pushing down his throat. Aaron was left with no other option than to swallow the turd if he didn’t want to choke and die. Luckily for him, the turd was moist enough for him to swallow with ease, as much ease one would have when swallowing a turd anyway, and got it down.

“That was such a mean shit, bro. Hope you enjoyed it.” Katrina said before she took a swig of her soda.

Aaron at this point wanted nothing more than to just get out of this sad position he was in, he knew his sister would like to toy with him but this drew the line for him. Aaron tried wiggling his face out but it just dug him deeper and deeper between her asscheeks, getting more than a whiff of her acrid smelling post-dump asscrack.

After taking a long swig of her soda, finishing it, Katrina lets out a long nasty belch like the slob she was. She still sat on his wide open mouth, it was actually very comfortable. “You know, we should start making this a regular thing, your face is quite comfy, bro. And we both know this is the only place you belong anyways, might as well start getting used to it.” Katrina says in a sadistic mocking tone towards him.

“No, absolutely not, I’d rather be anywhere but here.” Aaron thinks to himself, he didn't try to escape anymore, doing so would just end up with the opposite results of what he was trying to do in the first place. He also just realized there would be no point of escaping due to the blackmail Katrina has over him, this saddened him, he was wrapped around Katrina’s fingertips.

“Now bro we all know what happens even if you disagree to this, your mine now, you disobey, there are some major consequences. You obey, well we both know you get nothing, you just won’t have your life ruined haha. Now why don’t you be a good brother and be my toilet paper, my ass can’t be dirty, so get to cleaning it….with your tongue.” Katrina cruelly demands from her brother.

Aaron cries to himself, why couldn’t he have just done what his sister wanted?
