Sauna Slave
by saturnguy

Nancy sighed with relief as she entered the hot, humid air of her community center’s sauna, intending to enjoy the steam and relaxation as she took a load off from her busy office job. Tying back her beautiful, long blonde hair in a ponytail, the petite young woman entered the pine-smelling hot box and took a seat on the wood bench, a white towel wrapped around her slender body.

“Perfect,” she thought upon entering. “I have it all to myself!”

Taking a slow inhale of the thick, warm air, Nancy sighed again as she closed her eyes while she intended to bask in the pore-clearing steam for at least a whole twenty minutes. She could already feel her tense muscles relax and her shoulders lower as complete restfulness took over her body, blissfully enjoying her time away from the busy office. Her head briefly removed from the physical world, Nancy didn’t even notice at first as the sauna door swung open seconds later.

Opening one eye, Nancy almost jumped back in shock at the absolute house of a woman that stood in the open entryway. Standing at what must have been close to 7-feet in height, she had an immense body to fit, with hulking, broad shoulders that led down to enormous, beach-ball-sized breasts which hung down naked over her huge, flabby belly that stuck out so far ahead of her that it was mere inches away from Nancy’s face. From where she was seated, the smaller woman couldn’t even see this monster’s face from beneath the shadow of her enormous breasts, but she did see the long red hair the hung down loosely over the wide shoulders.

Her thick, chunky arms holding a cellphone close to her face, this humongous woman seemed completely engrossed in whatever she was doing and seemed to take no notice of the other person there in the sauna. Nancy was horrified as she turned around in place, her insane rear-end now facing the skinny girl. Each cheek must have been several times the size of Nancy’s own body, and likely weighed many times that as well. Bumpy with cellulite, the planet-sized booty stared back at the little girl with the deep, dark chasm that lay between the twin buttcheeks parting slightly as they jiggled with each tiny movement. Every time the twin mounds spread even the slightest, Nancy got a quick whiff of nose-stinging swamp ass.

This was Patricia, known by her friends as Patty, and she too had come to the community center for a little relaxation. She was a regular there, and often used the sauna the opening hour before the senior aqua fitness class was dismissed. Normally, she was the only person here, so she seldom bothered wearing a towel to her hour-long steam (not like they fit anyway), but as she turned around to sit down, the SSBBW failed to noticed that there was another patron already in her favorite place in the middle of the bench behind her. Sighing, Patty slowly lowered her titanic rear and took a seat in preparation for another relaxing steam, but as her boulder-like asscheeks touched down on the preheated wooden bench, she couldn’t help but feel something unfamiliar beneath her rear…

It had been only ten seconds, but to Nancy, it felt like she’d been staring into the rear end of the humongous woman before her for eternity. Somewhat of a health-nut, the scrawny girl was repulsed by such a display of fatness, feeling almost sick just looking at the expansive body. Her nose wrinkled in disgust as the woman’s BO became more apparent, already beginning to rise in the sweltering little room. Now too disgusted to relax, Nancy prepared to get up and shimmy around the monstrous woman when all of a sudden, the gargantuan ass in front of her began to bend over and quickly approach her unprepared figure. Eyes wide and paralyzed like a deer in headlights, Nancy opened her mouth to alert the obese woman of her presence, only to receive a mouthful of ass meat as her face, head, and her entire body was promptly buried beneath that giant bum as it sat down.

Patty leaned her full weight back and rocked from side to side, puzzled by the odd sensation beneath her. Whatever she’d sat on was pinned down to the bench beneath her cheeks, but most of it was on its way to becoming wedged in her expansive ass crack.

“Well shoot, I hope whatever this is isn’t anything important,” Patty giggled. “I haven’t washed my ass all week!”

Indeed, such an immense rear meant that hygiene was a difficult task for the SSBBW, and the lack thereof was certainly the first thing that Nancy noticed while her abdomen was submerged between the gelatinous boulders that were Patty’s cheeks, the woman’s titanic weight forcing the poor girl flat on her back and promptly wedged between them. Once she’d recovered from the initial shock from being sat on by someone many times her size, Nancy entered full on panic mode as she struggled to move and breathe in the very-moist ass that had just consumed her. Her slender nose managed to find the tiniest sliver of air within that swampy crack, but a sharp inhale quickly reminded her of just how “shitty” her predicament was.

Squealing loudly, Nancy kicked her legs in panic as the utter stench of unclean ass fried her nostrils and sent shivers of disgust and revulsion down her body. Her poor nose had found itself right beneath Patty’s grimy butthole, which on top of the stale funk and musk that already made up the atmosphere of that sweaty crack, made every breathe a torture. Eyes red and stinging, the immobilized girl couldn’t do much but moan and scream into the near-ton of ass meat that was weighing down around her, before taking in another brutal inhale of gnarly butt-funk.

“What…what is this thing?” Patty said to herself as she pondered what it could be that she was sitting on. Getting up to check was out of the question-she was far too comfy- but whatever it was, it felt kind of good sinking into her booty crack. It was massaging the deep, unclean, dank chasm almost as if it was moving on her own. Better yet, every few seconds, she’d feel what felt like cool breathe right against her asshole, generating a pleasurable tickle.

“Wait a sec…fuck, did I sit on someone?” Patty stammered as she realized that whatever it was beneath her butt felt rather alive. Spreading her tree trunk-sized thighs, the SSBBW felt a pang of shock as she saw a slender pair of legs sticking out from beneath her meaty crotch and dangling down over the bench, kicking furiously. The surprise of discovering that she was seated upon another Human being caused Patty to do what she normally did when she was startled: fart.

Crying in revulsion, with tears streaming down her face as she continued to inhale the sweaty ass pressing down upon her, Nancy kept up her squirming as she silently begged for the obese woman to move. The grimy rosebud directly above her nose suddenly exploded to life, belching an intense blast of searing air right into Nancy’s nostrils and then awash her face in a stomach-churning stench of rotten eggs and expired dairy. The skinny girl screamed for a second, before becoming overcome with gagging and retching as Patty’s asshole farted again, and then again as the titanic ass that imprisoned Nancy shuffled and rocked to the side, unintentionally rubbing the gas-blasting sphincter over the poor girl’s already burning nose, rubbing the inhuman stench in real good.

The deeply-muffled squeals that erupted from deep inside her stinky booty all but confirmed to Patty that there was indeed an unfortunate person trapped beneath her.

“Crap, what do I do, what do I do?” the gargantuan woman though to herself as her mind began to race. This girl under her probably wouldn’t just laugh this incident off. She’d probably complain, maybe even go to the police for endangerment or something. Worst of all, the SSBBW feared that she’d get banned from the community center, where she’d never be able to use the sauna again! Heart racing and combined with the intense heat from the steam around her, Patty started fidgeting in place, subconsciously rocking back and forth and unknowingly grinding upon the tiny girl wedged in her bum.

“Mmm, this feels sort of good,” she moaned as she bit her lower lip, increasing waves of pleasure being generated as she felt the slender features of the girl beneath her grind and scrape inside her dank buttcrack. It was like a booty-scratcher that was built specifically for her butt. Patty’s mind soon drifted away from the consequences of what might happen if her unintentional victim squealed to the cops, and more so on the rising ecstasy that the trapped girl was generating. Her sensitive pucker eventually found the unfortunate victim’s face, and Patty couldn’t stop herself from cramming her ass down hard as she moaned to the sensation of the girl’s skinny nose slide inside her slimy butthole

Nancy’s panic increased 10-fold as the already immense weight on top of her suddenly pushed down harder. The sphincter that had previously been hovering just above her nostrils now crammed itself right over her face, and to the skinny woman’s horror, her delicate nose slid up inside that foul butthole with an audible squelch. The SSBBW’s farts from earlier had remained inside that tight, swampy chasm and forced Nancy to endure its stench long after the fact, but with her nose now inhaling a direct sniff of pure colon, the poor girl’s entire body began to writhe and spasm in response to the inhuman fecal reek that flooded her senses and sent her on the road to insanity as she involuntarily began to inhale and exhale quickly in panic. This only expedited the mind-shattering aroma of Patty’s rectum flooding Nancy’s sense of smell and taste.

“Mmm oh yes, there you go, get up in there,” the humongous woman up above moaned to herself, dragging a pair of fingers to her clitoris that lay buried between her giant thighs, giving it a rub. Her body loosening up, Patty let loose a new barrage of farts, though she failed to notice as the sound had been completely muffled thanks to having to pass directly through Nancy’s nostrils. The heavy stench of hot garbage flooded the smaller girl’s already tortured nose and caused her to weep silently, ass sweat dripping up and over her quivering face. Another nasty blast of hot gas flooded her airways, the dry fumes billowing down her throat and filling her taste buds with the paralyzing flavor.

Body shaking as she orgasmed, Patty blushed as she hadn’t expected to get such a rise over accidently sitting on another woman. Her entire body sweating all over, her tangy BO filling the tiny, steamy room, Patty felt like going through round 2 as she thought of the intense odor that her accidental victim must have been going through.

“Sniff it, sniff my ass, smell it,” the SSBBW cooed down to her thighs, shaking and grinding her ass again on Nancy. She’d gone too far now, there was no way that this little girl wasn’t going to press charges. Exhaling slowly, Patty concluded that she would not be able to let this person leave the sauna without her. She was going to have to do something.

As if she had any choice, Nancy sniffled and sniffed inside her ass prison, body now soaked with reeking butt sweat as the crying girl gagged gently into the tight, moist environment. Another silent fart singed her nostrils, making Nancy’s head feel heavy and full as it struggled to deal with the noxious odor. For a second, it seemed as if her prayers had been answered as the unbearable weight suddenly lifted off of her, sending in a flood of fresh (albeit hot) air that alleviated some of the terrible smells that she’d been enduring. The fetid ass that had been seated on her pulled away, and in the dim light of the sauna, Nancy watched as her would-be tormentor turned around and looked down at her crippled form.

“Hey…sorry about sitting on you, I honestly didn’t mean to,” Patty said innocently. A butt-print of sweat marked the wood bench, where in the center was a soaked, crumpled form a girl whose once pale face was no longer pale. Beautiful skin now filthy with butt grime, the SSBBW was somewhat impressed at how bad this girl looked having been under her big booty.

“Fu-fuck you!” Nancy stammered, enraged at having to endure such disgusting torture because of some stranger’s carelessness.

“Oh dear, I hope you won’t press charges or anything,” Patty asked, blinking cutely.

“I will! I hope your nasty ass gets locked up for a long time!”

“That’s a shame, I guess I have no choice then…”

Patty left the room for a second, where Nancy was just beginning to recuperate enough to sit up after the whole ordeal. Rubbing her reeking, browning skin, the little girl shuddered in revulsion just as the hulking woman reentered the sauna carrying a tiny bottle in her hand.

“I bought this shrinking serum off the black market to shrink myself a man and keep him to myself forever, but I guess you’re going to have to be the substitute,” Patty smirked evilly, bending down and using her strong arms to grab hold of Nancy’s face. The weakened girl was powerless in the firm grasp of Patty as her mouth was forced open, and the massive lady unceremoniously dumped the whole bottle of liquid down her throat. It had an odd, acidic taste as it went down. Backing away to block the door, Patty watched in amusement as Nancy’s body began to shudder and shake.

“Shrinking serum? What the hell, that’s impossible…” the scrawny girl thought, her vision going dizzy. Locking the door to the sweltering room behind her, Patty licked her lips as she watched Nancy fall unconscious, and shrivel up and shrink right before her very eyes.

Opening her eyes after what felt like the deepest sleep she’d even been in, Nancy felt groggy as she sat up in her bed and stretched. What a strange dream she’d had, where the nightmare had caused her to think twice about taking her trip to the sauna as she’d planned to today, lest she run into some hugely obese woman that would sit on her. Laughing at the thought, Nancy couldn’t help but wrinkle her nose at a rather foul smell that seemed to be permeating from around her. Her bed STUNK. Looking down, Nancy quickly realized that this wasn’t even her bed. Panic setting in, the tiny girl realized that her hand and legs were strapped onto the fabric that she way laying on, which in turn looked like a massive, purple parachute. A familiar voice loomed over her, and a shadow casting itself over the little girl made her realize that the nightmare was far from over.

“Ah, you’re finally awake!” Patty exclaimed as she looked down on her shrunken victim who had been fastened to the inside of a spare pair of panties that she had in her locker at the community center. Emitting tiny screams of pure horror, the SSBBW giantess smirked playfully as she held the panties up to her face.

“So you enjoy saunas, pipsqueak? Well, my rancid swamp ass is quite the sauna on its own, so do enjoy,” she cooed as she spun around and putting the garment around her legs, pulled the underwear right up and over her booty. A final scream of anguish from the shrunken girl was quickly muffled as Patty intentionally gave herself a wedgie and ensured that her little prisoner was firmly placed right between those mountainous cheeks. Poor Nancy was immediately greeted with a mouthful of ass sweat as a familiar thick, humid atmosphere took over her senses and stifled her with the horrific odor. In the darkness, she could just make out the now supersized sphincter of her gargantuan tormenter, and just as the tears to her little face started flowing, the farts started blowing.

Patty sighed as she ripped a wet, bubbly fart directly on her shrunken victim, already feeling herself go hot at the thought that the 2-inch girl was experiencing what must have been a hurricane of gas up there. As she waddled to her truck, the thoughts of what nasty tortures that she was going to put Nancy through danced through her head, and she couldn’t wait to get home to pleasure herself to her brand new slave.
