Road Trip: Sunday
by skeezan

It was early in the morning just about quarter to seven and the siblings car was stopped in a random parking lot. Fionna's brother was sleeping having become too tired to continue driving. Unfortunately for him Fionna woke up first. She was not happy with what she saw, not in the slightest. It seemed her brother had not only stopped during the night he also left the car to clean himself up and possibly the worst insult of all he rolled the windows slightly down to air out the stink Fionna was making all throughout the night. The fuming girl raged her mind filling with all manner of punishments for her slave brother. Then she saw her dirty panties from the other day, now caked in dry shit and from that a sinister plot emerged in her mind.

Very carefully Fionna pulled out her bag of panties from the back which her brother so generously packed and placed it beside her. She gave it a quick whiff to make sure it was still potent which thankfully for her it did. From there Fionna carefully etched forward and poked her sleeping brother in the head just delicately enough so it wouldn't wake him and shrunk him down to about three inches. Finally, picking up her completely brown panties Fionna moved them to her rear and let out a short SBD.

PPPPPRRRRRRRRRRRRSSSSSSSSSSS

Sparing no time after that Fionna grabbed her brother and stuffed him in the panties wrapping his body around the disgusting cloth with utter recklessness for his well being. Her Brother was ripped from his blissful dreams and suddenly submerged into another hellish torture of his younger siblings design.

“So Bro but it seems you disobeyed literally every single demand I had for you and you know what that's fine just be aware that you are the only person to blame for the punishments you will be receiving today.” Fionna said as she threw her tiny brother on the seat next to her and then dumped he entire contents of her dirty bag of panties on top of him leaving him at the bottom of a pile of sweat stained, fart stained, and above all else shit stained articles of clothing. Fionna made sure to sit on the pile to squish all that stink down onto her brother so it would have nowhere else to go but his nostrils.

“There you go Bro punishment one of......how ever many it takes for me to decide you've learned a lesson and look I'll even gave you some fresh gas to keep you company.” Pressing her posterior further into the pile Fionna let out three long rippers each soaking in the atmosphere that surrounded Fionna's brother. Looking at the pile it seemed to have visible cartoon stink lines emanating off it. Fionna was satisfied though and made her way out of the car making sure to roll the windows up all the way. Her brother meanwhile was left to simply writhe in his own torment.

Fionna's brother laid there surrounded in by the steaming garments clutch at his nose to avoid the stink in vain. Every single awful odor Fionna was capable of was in this pile and he was at the very centre of it. He thought back to last night and began to regret all of it. He assumed the entire day would be this and only this, torment enacted by his vindictive sister for not being the most obedient of slaves. He was of course right but none of it mattered right now though he was still there trapped underneath something as innocuous as his sisters stinking panties. The dried shit from yesterday was right in his face offering a very up close opportunity to smell the awfulness of Fionna's ass even when she wasn't in the room. Fionna's brother was powerless unable to move, unable to leave, unable to do anything except breath and (due to the close proximity of many of the panties) taste the worst parts of Fionna. Just as he was sure she intended. He continued to lay there waiting, breathing, and occasionally tasting the surroundings all until Fionna would release him.

Conveniently when he finally succumbed to this Fionna came back sporting a few empty fast food bags. She came in and sat next to the pile throwing most of the bags on the floor. Fionna looked over at the pantie pile with warmness knowing that her deceitful little bro was trapped there. Still there was more punishment to be had and so Fionna let him out carelessly tossing the panties all across the interior of the car until she found him. Light shined in for her brother as Fionna face filled his entire frame of vision. Slowly she moved her mouth closer and closer.... until she let out a huge belch right in his face.

“Whew, been building that one up for a while. Anyway punishment one is over how'd you like it?” Her brother went to speak but then the pungent scent of her burp wafted towards him stopping her brother right in his tracks. “Yeah never mind. Now look I know you've made some mistakes but thankfully I am a just master so I have chosen to forgive you.”

“Oh give it a rest sis you're starting to buy into your own bullshit.” Fionna's cheery face melted away revealing a cold calculated look that strikes fear into her brother's very soul. Without any hesitation She threw him into the front seat then unshrunk him back to normal size. The relief at no longer staring up at his sister's titanic form was soon destroyed as each of Fionna's sweaty feet were placed on the driver's seat head rest effectively putting her brother in the middle of a foot sandwich.

“These feet will remain there for the remainder of the trip if I feel them get sweat or itchy you will lick them to your best ability..... and hey just for the fuck of it let's add another level of torture to this.” Fionna turned around and grabbed the infamous brown panties and shoved them right in her brother's mouth. The taste of dried shit and stale farts were horrible and he instinctively tried to spit them out only to have one of Fionna's feet cover his mouth.

“Ah ah ah you keep those in there and clean em' only with your mouth of course cause you'll be driving, oh and don't worry if you finish I'll start working on another pair to stink up for you and even if I don't there's still a lot more options back her.” Unable to form any response Fionna's brother swallowed the sweat shit stained garment. Along with this her toes went slightly into his nostrils giving Fionna's slave brother a chance to taste the awfulness of her butt and smell the awfulness of her feet. “There now you can enjoy the best parts of being my slave and we won't lose any time on the road hehehe, anyway start driving. NOW! ” Fionna finished her point by hitting her brother across the face with her might foot followed by a deep laughter that laughter that he hated but Fionna's brother was helpless she could decimate him with a flick of her finger so with the dirty panties being in his mouth and the sweaty feet in his nose Fionna's brother drove off hoping to god no one would see him.

3 HOURS LATER

Driving was now an arduous task for Fionna's brother. Bags grew under his eyes, the car had become a garbage dump of Fionna's filth, and then there was Fionna herself who was taking every opportunity to make the next miles worst than the last. There was the obvious like Fionna's constant gassing that along with the windows being completely rolled up created a atmosphere of hot sweaty farts. Then there was the bigger things like Fionna shoving her steaming feet into her brother's face and demanding he lick all the sweat off them while they covered his eyes. They very nearly crashed but Fionna still made him do it, sucking and licking all of her two moist feet. Meanwhile Fionna laughed and laughed thinking in her head how well she must be doing on the Goddesses little “test”. So as per usual Fionna was gleaming with joy and her brother wanted to kill himself as the two began to approach a toll booth.

“Alright slave brother I have an fun idea for a game we can play.” Fionna said at the sight of the toll booth. Her brother just groaned. “You remember Guess the Smell and in case you forgot I'll....”

“You'll fart next to me and I'll have to guess what you ate that made your fart smell that bad and you'll make me finish it before we get to toll booth.” Her brother correctly guessed. They had “played” this game many times once Fionna was given her gift and needless to say her brother was not a big fan of it.

“Close but you'll be shoving that cute little nose into my even cuter booty... sounds fun huh?” Her mind also filled with memories of playing this game remembering how fun it was to see her tiny bro squeal and squirm as he guessed every food he could think of before being silenced by another one of her thunderous gassing's. Fionna was desperate to have it happen again.

“Fionna please I don't wanna play this game besides we won't finish before we get to the toll booth. ” Her brother pleaded as they were edging closer in a long line at a toll booth.

“Oh c'mon you wanted sibling bonding this is exactly what sibling bonding is. You know comradery and.....stuff.” Said Fionna as she placed her posterior directly next to the head rest. Her right buttcheek rubbing against Fionna's brother's other cheek allowing a fair amount of sweat to pour onto him. Capitalizing on the already uncomfortable scent her slave brother was sure to be smelling Fionna let out a loud slapper of a fart.

BRAAAAAAAAAAAAAAAPPPPPPPPPPPPPPPPPFFFFFFFFFFFFFFFFFFFFRRRRRRRRRRRRRRRPPPPPPPTTTTTTTTT

“Now guess!” The fumes trailed down towards Fionna's brother's nostrils causing him to sputter and cough out the stench as best he could. Fuel was added to the garbage dump the car had became only this time it was much, much closer than Fionna's brother would have wanted. They inched further in line with her brother still desperately trying to fan the smell away from him, while Fionna continued to get annoyed. “GUESS!”

“I oh...*cough* oh god.”

“Just shut up and guess!” Fionna grabbed her brother by the back of his head and stuffed him deep into the confines of her sweaty reaking ass letting out a short fart to greet him.

PPPPPPPPPPPPPPPPPPPPPPPPPPPPPFFFFFFFFFFFFFFFFFFFFRRRRRRRRRRPPPPPPPPPTTTTTTTTTT

His muffled screams were music to Fionna's ears as she tightened her grip to make sure he could get the best whiff possible. Fionna held him deep into her rear laughing and gassing her slave brother with such glee she nearly forgot about the line they were waiting in. Quick as could be Fionna gave her brother one last fart and pulled him out of her behind with a loud squelching POP! “Here's the deal you're gonna tell me what I ate to give off such lovely gas and in return I won't humiliate you in front of the toll booth guy, so drive up and get ready to tell me what I ate.”

Hesitantly he complied driving up to the toll booth while Fionna hid in the back positioning her butt in such a way that the farty air would still travel directly into her brother's face yet not be seen by anyone else. Fionna let out short SBD's as her brother unrolled the window releasing a days worth of gas, sweat, and unwashed panties. The man covered his nose as he addressed Fionna's brother. “Please pay the defined toll sir.” The toll booth man stepped away from the booth for a second likely to throw up. Fionna took this time to give her brother some fresh gas while they waited.

BRABBBTT FRRRRRRRRAAAAAAAAAPPPPPPPPPTTTTTTTT BUUUUUUUUUURRRRRRRRSHHHHHHHHHHHHHPP

“Fast food I dunno just shut up and let me pay.” Her brother said as the aroma clinged to his face no matter what he did to stop it. Fionn meanwhile was getting rather upset with her brother's disobedience today and moved her ass just a little bit closer to his face. Stink radiated onto him the stench was too strong and sent Fionna's brother into a fury. “Look I've been driving forever can you shut that fucking ass of yours and....”

“FINE YOU DON'T HAVE TO DRIVE ANYMORE WHY DON'T YOU TAKE A REST INSIDE MY BUTT!” Fionna cut her brother off and in an instant Fionna turned around and touched her brothers head shrinking him to a small spec on the driver's chair. He only had enough time to scream before the titanic ass consumed him. The whole thing took about five seconds leaving only the toll operator with a look of bewilderment as he saw Fionna now in the driver's seat. She paid her toll then drove off the faint cries of her brother tickling Fionna's crack

12 HOURS LATER

Fionna drove for an eternity her brother serving as a seat cushion the entire way. The tiny man had been overcome by the shear force Fionna's ass could give by sitting down and because of this he was at it's mercy. Sweat seeped onto him endlessly, the air was comprised solely on the ass gas Fionna would give him, and she was double sure to grind into her seat at every single opportunity she had like she was pressing the smell and the sweat onto her brother's very being. He stopped his cries eventually realizing they were falling on deaf ears, so he did the only thing he could, wait and take all Fionna was giving him. This waiting lasted twelve hours and at no point did Fionna so much as give him a break, all that time Fionna's brother was being tortured and humiliated by his little sisters who was simply sitting in her chair nonchalantly farting.

Even when it seemed it was over fate made sure it wasn't as when Fionna got up off the seat her brother came with her glued by the sweat to Fionna's crack. Each step rubbed and smeared him across the still reeking rear end Fionna even made it a point to blast out a few short farts with each step. Fionna had been walking a while her brother even overheard her talking to someone but that was ultimately drowned out by another of Fionna's rippers. She entered a room where finally after more than a day of being glued to this enormous end Fionna's brother was ripped off that end by Fionna. His sight no longer filled with ass but was instead filled with his loving sisters face. He looked around to see they were in a hotel room Fionna was sitting on the bed cupping him in her hands.

“Hey slave bro have a fun day?”

"Whatever just please make me big and let me go to sleep" he pleaded in the palm of her hand.

"Oh sorry I'm still a little mad so I found this jar and I found this lid and I thought to myself how can I use these two items to torture my bro" she said pulling the aforementioned items out of her bag and dropping him in the jar.

"God damn, I hate you" he said from inside the jar

"Goddess Damn, I hate you" Fionna corrected.

“Oh just shut up like what I say is going to change what happens next.”

“Well...I mean duh.” Fionna said as her nude rear covered up the top of the jar.

PPPRRRRRRRRRRRRRRRRRRBBBBBBBBBBBBBBBBBBBBBBBBBBBTTTTTTTTT. The tick gas quickly filled the small prison as her brother desperately tried to claw his way out but made no efforts.

"You think that’s enough for the entire night probably not lets give you some more" BBBBRRRAPPPPT PPPPFFFFFFRRRRRRRRBTT SPLOOOORSHPBT

"Oh ya that was definitely enough just remember not drown in that" Fionna said as she closed the lid over the now shit filled jar on the counter and made her way to bed.

Her brother simply side and slumped down the side of the jar wall making his lower half completely submerged in shit clinging to the the fact that tomorrow was the last day of this awful road trip.
