My Sister Farts on Me in the Car

By: Spongeboy1521

My whole family was on the car ride to our grandparent's house who lived about 3 hours out. Our parents sat in the front, our dog occupied the middle row (He gets carsick and being closer to them was nice for him) and Jane and I got the back row. So we were pretty secluded from our parents, only being able to see their heads.

The car ride had gone as normal for the first hour, Jane and I played games and whatnot. Although I could hear Jane's stomach rumbling.

"Are you hungry?" I asked

"No.."

"Oh.. Then are you feeling alright?"

Jane leans a bit closer to me so that she can whisper right into my ear.

"I'm sorry about this."

She leans back to how she was originally sitting. I assume that I had a confused look on my face while Jane's was more slight discomfort. Before I get into what happens next I'll give a little overview of how she was dressed. It was nice and simple, oversized vans t-shirt that fell to her upper thighs and a pair of yellow-green running shorts that were pretty much completely hidden under the shirt. And her hair is done up in a ponytail.

Jane looks at me with a sorta nervous grin before she leans away from me, sticking her butt out at me. Fssshhhhhhh A long thick fart pushes its way out of Jane. She sighs and lets her muscles relax after it's over. The smell hits me first. It's 100% disgusting. I might as well have been sniffing the inside of the toilet after she just went to town on it. It was completely shit scented. I normally like the smell of her farts but this was a little too much even for me. I had to resist gagging. And apparently that was obvious as Jane started laughing. Although her laughter didn't last too long before the smell hit her too and she began to rapidly wave her hand around in front of her face.

She quickly directly all the air vents back at us in hopes that the smell wouldn't reach our parents.

"Jeez.." I say, with my nose plugged.

"I'm sorry~! I didn't think it was going to stink that bad!" She said, half whispering in hopes not to be heard.

"Please don't tell me there's more of that coming." I said, looking her pleadingly in the eyes.

Jane looked down at the floor embarrassed for a few seconds before looking back up at me.

"Sorryyyy" She says under her breath.

"Oh no..."

Psshhhhhhh - FFSsshshshhhh Jane forces out two misleadingly quiet farts into the seat. Our car seats were made out of that super soft material, I'm not quite sure what it's called. But it soaked her farts right up as she unloaded them. After a few seconds the smell still hadn't hit me, I guess it was all trapped under her ass.

"Those made my butt real warm."

Jane squirms around in her seat a little.

"Jane, you can't hold them in?"

"You think I can hold all this in for two hours?!" She says patting her stomach.

"I-"

PFfsssssss I'm immediately cut off by a small airy fart that slips its way out of Jane's rear. She once again sighs in relief. She keeps her thighs clenched together and her butt flat to the seat so no smell leaks out. Jane ever so slowly leans away from me, letting all that gas that was trapped under her ass free to the open air. I don't have even a second to think before the smell of rotting sulphuric shit accosts my poor nostrils. This was far too bad, even for me. I wish I could explain to you all how truly disgusting this smell was. It smelled as if she full on sharted herself, and yet it was just her silent air making all that stink. I coughed a few times before covering my nose and mouth with my hands.

"Gosh these are bad..." Jane says

"At least mom and dad can't tell" She adds with a giggle.

"I can't breathe!" I say

Jane giggles, "Don't even think about asking for any windows open, no one is allowed to know this is happening alright?" I stare into Jane's eyes beggingly. She stares back with barely any care.

"Op, we're just kinda stuck like this for a few hours... You might want to at least try and get used to the smell."

I suppose she was right, getting used to the smell might be the best thing to do. But I couldn't bring myself to move my hand from my nose as I knew what was waiting for me in the seemingly clean air. Jane looks at me with a face that says "Well, come on then." I slowly move my hand away from my nose, although I don't take a breath yet. I wait a few seconds. But I finally inhale through my nose and nearly gag. The smell has dissipated somewhat but it's still rancid.

"Just a few deep breaths, you can do it.' She whispers.

I take another deep inhale through my nostrils and my eyes almost start to water. I stare at Jane and shake my head. She slightly rolls her eyes. "Fine, we'll do it the fast way." In a single swift motion Jane unbuckles her seatbelt, lifts herself onto her all fours on the seat so that her ass is facing me and leans against me.

"Hey!" I manage to yell before, PFSSSSSSSSSSS A long, heavy, and humid fart eases out of Jane's ass. She quickly hops back into her normal seated position.

"Is everything alright back there?" Our mom asks.

Jane stares at me, then back at our mom "We're good!" She says. Mom gives us a thumbs up. "Starting to get used to it yet?" Jane asks. While Jane was having her little conversation with our mother I have been trying not to cough up a lung choking on the fart that she had just pushed into my face. It felt like my fight or flight response had become active and I just wanted to do anything that was going to get me out of there.

"I'll take that as a no." Jane says, starting to chuckle. "Well you're safe for now, I don't feel any more." She adds patting her stomach again. Now it was my turn to let out a sigh of relief. The smell was still incredibly strong, and I stuck my face up right against the air conditioner vent to let the cool, not tainted air blow up my nose instead of whatever abomination Jane had created between her ass cheeks. Jane must have thought it was a good idea since she started doing the same with the vent on her side.

"Luckily" for me the rest of the car ride went normally. No more farts were blown. Although once we got to our grandparents house, it was a whole different story...~
