A few hours later, I blinked bleary, bloodshot eyes, and checked my alarm clock, sitting across the room.
1 AM. Rachel had been farting directly up my nose for the last 2 hours, and showed no sign of relenting. I'd rarely ever seen her sit so still for so long. She must really be enjoying the situation.
At this point, all fight had completely left me. I laid there limp as Rachel used me as her personal fart cushion. I'd sucked most of the sweat out of her socks at this point, forced to swallow what felt like gallons of her rancid sweat. The taste of salt and spoiled food still encompassed my entire mouth.
The night brought cool air outside, so Rachel's ass finally stopped sweating. I could feel the old sweat still sticking to my face, but at least it had stopped dripping down my nose. Every time I inhaled, all I could smell was stale, stagnant sweat and her horrible gas. I swear that woman has twice as many sweat glands as a normal person.
The only light was her singular desk lamp. I think she was doing homework. This only added to the humiliation as I sniffed her latest toxic emission. She was just using my face as a piece of furniture, to be paid no more mind than the chair my head was propped up on.
The tip of my nose was bent backwards towards my eyes, my nostrils wide open and pointed directly at Rachel's asshole. I was sniffing it straight from the source.
Suddenly, I felt her buttcheeks clench a little, making it harder to breathe. I'd panicked the first few times it happened, but now I knew what was coming.
Brrrrrrrrrpt
A dry, hot fart clawed its way down my nostrils, and I could do nothing but try and breathe it all in, to give myself at least some fresh air. I gagged again, but Rachel had long since stopped responding to those, not even to laugh at me. I wasn't even sure if she could hear it through the packing tape and socks.
Right as I was starting to filter the last of the waste dump that was Rachel's bowels, she tensed again.
Ssssssssssssssssssssssssssss
This one was long, hot, and practically silent. But, from my unwanted yet extensive experience with my big sister's bowel movements, I knew that it was only going to be worse.
The smell scorched the inside of my nose as I was forced to inhale the entire thing. It was like someone had taken all of the worst parts of the cafeteria's food, and left them to rot for several months. I don't know what was happening in Rachel's stomach, but I did not want to be on the receiving end of it.
I began spamming from the horrific smell, but Rachel didn't even acknowledge it. She knew full well the toxic swamp she was responsible for creating. She seemed to be enjoying my suffering more and more, though. This fart was particularly long, too, so I would be choking on this one for a while.
After several minutes of labored, tortured breathing, the air around my face was getting no better. I don't know how much longer I can take this treatment.
Splrrrrrrrrrt
Without warning, a wet fart sprayed out of my sister's butt and directly up my nose. I was forced to inhale it, no air escaping the vacuum seal of Rachel's damp leggings to my face. The toxic miasma around my face got even wetter, and more warm as well.
Apparently it was a bit wetter than Rachel expected, because she gasped and shifted her weight. This freed my nose from her crack at least partially, but then as she kept shifting, it got even worse.
Suddenly, my nose was scraped against a part of her leggings that was even more warm, sticky, and wet. At this point I started screaming and struggling again, and Rachel did eventually get up.
"Fuck, I think something from the dining hall isn't agreeing with me. I'm gonna ruin these pants."
I hoped that I would never have to experience anything like that again, but at least it looks like biology is going to force Rachel to let me go, even if she doesn't want to.
Above me, I saw her shrug. "Eh, these panties were getting old anyway."
Unexpectedly, she started peeling her leggings off of her butt cheeks. They were slightly stuck with sweat, peeling off of her damp skin inch by inch. I shuddered, practically being able to see the miasma rolling off of them.
Rachel pulled first one leg, then another out of her leggings, exposing most of the skin of her perfect butt. It was perfectly round, each cheek sticking out several inches. They both were firm but soft, as I now knew, with a slight jiggle to them as she moved around pantless.
Her toned thighs were now exposed to the air, the muscles visibly pulling taught as she stretched herself out. Every part of her legs glistened with the sweat that had soaked her leggings. The fan blew the sharp tang of her armpits into my nose when she raised her arms above her head, but at this point I had experienced far, far worse.
My older sister's butt was practically swallowing a pair of lacy black panties underneath. They barely covered anything apart from her crack, and were soaked even more thoroughly than the rest of her clothing. My nose had given her a deep wedgie, but she didn't seem to be in a rush to do anything about that.
On the fabric that was covering part of her right buttcheek, I could see a few small holes. These were apparently very well-worn, the fabric thin and faded. I'm not sure how good a job Rachel did of washing them.
I was utterly amazed that she was giving me a full display right now. As much as I hated to admit it, Rachel's ass made her look like a goddess. Unfortunately, its emissions had disabused me of that notion.
By the nature of being roommates, I'd seen her partly undressed before, but Rachel had never shown this much skin before. If she was just going to let me go, why strip first?
Then, she started chuckling. It all clicked.
"That's unlucky for you, bro. I'd hate to ruin my favorite pair of leggings, so it looks like you're gonna have to take it from even closer."
I started screaming at the top of my lungs, struggling for all I was worth. There was no way I was spending the night nose to butt with my big sister wearing nothing but a pair of skimpy panties.
I'd never imagined Rachel would take it this far. I knew she was mad, but I didn't think I'd pissed her off that badly. Regardless of what I thought, she was about to cross a line she's never even approached before.
Even without the socks, my screaming would've been no use. Nobody was even on our floor, let alone close enough to hear my struggles. Rachel grabbed either side of my head, and began lowering herself again.
I managed to shake loose, so she sat on the side of my head by mistake
Sighing, she stood back up. "Unless you want my panties to replace the socks in your mouth, I suggest you stop struggling." She tilted her head. "Hmmmm, maybe I'll do it anyway. I wonder how you'd like the taste of fresh skid marks?"
My bloodshot eyes shot wide open, and I frantically shook my head.
"Alright, then. Be a good boy and sit still. I'll consider letting you up later."
