"Uuuhuu~♥" Courtney groaned as she ground her fat behind into the seat, unknowingly smearing you into the slimey fabric which contained her sweaty asshole. Her shorts whined and groaned as they strained to fully contain the abnormal sized buttmeat, leaving little to the imagination as part of her thick cheeks would pour out from her waistband, while stretching the fabric so thin that someone with your diminished size could gawk inbetween them. "Gawd, why did I have to eat Taco Bell BEFORE my workout." She whispered to herself as she repeatedly slapped her forehead. "It's such a rookie mistake."
You, however, were being relentlessly steamrolled by the dank, crevice of her clothing, forced to inhale her musky scent along with the stale leftovers of her previous booty blast. Coughing and whining, you couldn't believe your current predicament as you had to find a way to get out of her rank crevice. But your train of thought was interrupted as Courtney flexed her rear muscles, and sent her slimey hole rocketing against the strained fabric, further punching you into a indistinguishable pulp beneath her. "Fuck my shithole. This itch is getting on my plump nerves" She exclaimed with annoyance as she reached her hand behind her back, inserting a finger into the deep crevice.
You tried to scream, but your pathetic, helpless new size made getting her attention pointless, as you felt the tip of her finger strike the back of your head. Courtney tried to muffle a groan as she cooed happily, smearing your face into her bloated pucker to ease the irritation. Though unknown to her, she had just wedged her friend's head inbetween the threads of her shorts, leaving you firmly trapped as you stared in utter horror at the twitching hole above.
Unknown to Courtney, the itch was originally caused by a rogue mosquito, who had found itself infiltrating her bedroom while she slept and stung her just an inch above her bloated asshole. Obviously, the mosquito died within moments from the stale remnants of Courtney's buttfumes, though the itch was persistant and refused to go away.
Courtney sighed. "Deciding to try their new 'Flatulent Farthole Destroyer Deluxe' meal was a big mistake. God, is anyone in a worse situation than me right now?"
You felt like punching her in the face at that last comment, though Courtney had other plans for you, as she resumed to grind her fat rear into the bench beneath her. This time however, something was different. Feeling some kind of bump in the back of her shorts, which seemed to dampen the itchy sensation of her sphincter, Courtney cooed once more as she pressed her rear further into the seat, unknown that the bump she was using to scratch her asshole was actually your face. Courtney didn't mind though, as she was relieved she could manage it without having to shove her finger back there in a public place. Though trying to balance clenching her bloated farthole to prevent more of her taco sharts from bursting out, with the euphoric sensation of having your face scratch her itch was starting to get too much for her. It was only a matter of time before something would go horribly wrong.
Whilst her farthole struggled, you were forced to endure the unyielding pummeling of her asshole as it twitched beneath the fabric, like a stampede of elephants, Courtney's grimey hole punched and flailed at your face as it stretched and strained the fabric beneath, swelling up until it eventually crushed your head into a flattened mess. You'd let out an agonizing howl of pain, causing her asshole to descend a few inches back into her crevice before it rocketed right back and crushed your face.
Soon, your entire world shuffled as Courtney begun to stand. Her meaty cheeks firmly clapping together, trapping you in absolute darkness, though eventually, slivers of light would periodically enter as she started walking, her massive buttmeat relentlessly grinding and crushing you further into the depths of her crevice.
"Uuuhuu~ On second thought, hope Gabe won't be back for a while. Got some tricks to get this itch out for good that I know he's not going to like." Your gaze focused on the sweaty pucker looming above once you heard her comment, and as if rehearsed, her puffy farthole begun to twitch and bulge, as a tormented groaning and churring sound thundered inside her lower intestines.
You eventually felt a devastating earthquake as Courtney had finally planted her monstrous booty back onto the seat of the stationary bike. You began thrashing and flailing, squealing at the top of your lungs, but your diminished form made it impossible to get her attention from down here.
