Stretching and contorting your body, Charlotte widened your frame until you were incredibly long and thin. Grabbing your aunt Mia's yoga mat, she stretched you out all across it. Rolling you out into place where Mia's mat had just been, Charlotte admired her handiwork. "Sammy?? Where'd you go? I certainly don't see you anymore!" Charlotte mocked slapping her dirty foot across the mat a few times. "Oooooooh extra squishy." Charlotte knew her ditsy mother stood no chance of knowing the difference between how her mat looked before and how it looks now.
The next thing you felt were massive earthquakes as your bubbly aunt skipped back into the room, shaking your whole world as all you can do is stare helplessly up at her. Tossing her phone, now playing extremely loud pop music, to the side, Mia hovers her right foot over you before slamming it down onto where your face had been contorted to. Her sweaty foot recoils off of your face to your surprise, "Uuuhhhh this mat is really squishy, and it almost feels warm?? Is yours the same Charlotte??" You glimmered with hope, seeing this as your last chance at salvation before being doomed to being used and abused by your oblivious, curvy aunt.
" Nah, mom I think that's an advanced new kind of mat, Shannon must've shelled out the big bucks for it. I figured since you're the yoga pro you should get to try it out! Also, since it's heated its much better suited for hot yoga, so I already cranked up the heat in here!" You scoffed mentally, there was no way your aunt no matter how unobservant, forgetful, and exuberant would believe--
"No way! Eeeeeek that is just like-so amazing! It would be my pleasure to break this puppy in! You don't mind if we do some working out and hot yoga do ya, Char?" You died inside. Smiling softly down at you with gorgeous radiance, you witnessed your aunt once again hover her sweaty, stinking foot over your body wiggling her toes childishly causing bits of old crusty sock lint to rain down onto you before slamming it down. "Let's get physical!" Your aunt exclaimed, giggling to herself, before beginning to run through some beginning stretches. Despite your senses being dominated by your aunt;s sweaty foot on your nose now, you could still hear Charlotte snickering evilly from the next mat over. Your body had begun heating the soles of Mia's feet, causing a blissful sigh to escape from her lips. But to you, you could already feel droplets dropping down her toes onto your face as well as a circle of foggy perspiration forming where her feet met your face, no doubt leaving prints on your body. Moving onto her actual workout, your aunt began doing jumping jacks, each foot straying away from you before slamming directly onto you once again. This continued for what felt like an eternity, before droplets began raining down onto you snapping you back into your torture. You knew your aunt was naturally sweaty, but at your size this might has well have been a rain shower. Drops of sweat rained down relentlessly, bouncing off her body due to her explosive jumping. Stinging your eyes, getting the salty residue in your mouth, and tainting your nose with its rancid smell you were forced to whimper silently as your aunt beamed, loving each squish against the bottom of her feet. Without warning, your aunt collapses onto the mat, sitting cross legged exhausted. You watched in horror as she brings her extremely visibly soaked and sopping spandex shorts down onto your tongue!
Feeling an odd, wet sensation in between her ass cheeks, your aunt does a surprised hop, turning to lock eyes on your tongue. Rubbing her clammy hand over your already battered tongue, your aunt says "Hmmmmmm...Charlotte what do you think this part of the mat is? It feels like a lump but its kind of wet?"
"Oh....." thinking on the spot, Charlotte had to think fast. "I think that's the washing station? Yea, some kind of highly absorbent material to wipe sweat on so you don't need a towel or anything. It should absorb any sweat and actually any kind of dirt or grime too!" Sweating nervously, Charlotte fidgeted hoping her mother would believe her insane lies a second time.
"Well thank god for that...I mean seriously, how can someone be expected to bring a clean towel to the gym? I'm already stinky in the morning, and I of course want to get the most out of my pants before washing them, so we're going to need some way to clean ourselves when we can't be bothered to shower BEFORE the gym!" With that, you screamed out as hard as you could, only producing a mild buzzing on the bottom of your aunt's gigantic bubble butt. "I've been wearing these spandex for over a week during my workouts, I hope Shannon doesn't mind if I fully use this device to it's max...I'm sure she can just wash it when I'm finished using it..." With that your aunt began the worst experience of your life. Grinding her stinky, sopping shorts across your face, you felt the dam burst as the sweat could be contained no longer. Rubbing back and forth aggressively across your tongue, all you could taste was what tasted like months rather than a weeks worth of sweat and stale farts and who knows what else get rubbed deeply onto you Rivers of tainted old and new sweat drained out of her shorts onto you as your aunt moaned happily rubbing her asshole against the heavenly lumpy "device" she had found implanted onto her mat. Stretched to their limit, you could see through your aunts shorts at the menacing dirty hole that looked as if it was dying to get closer to you. Minor brown stains probably invisible to a goddess such as Mia were visible to you and caused you to retch. Even Charlotte found herself blushing, witnessing the inherently lewd display that to your aunt was just trying to get out of having to wash her most favorite pair of workout shorts. At least that's what it started as, but your aunt was red with arousal at feeling this wet lump rub her up and down, subjecting it to her most vile desires. Losing herself in the pleasure of the moment, your aunt accidentally let you slip a little too far, nudging her asshole and letting loose a long, steamy fart onto you. The room was already sweltering with the two girls panting, fatigued bodies sweating and heavy breathing creating what looked like a rain forest and the fart sank to the bottom of the room, only ever absorbing onto you. "Oh my....excuse me honey this mat seems to draw everything out of me. And absorb everything too!" Blushing like mad, your aunt continued her sensual assault on you, not satisfied until you had licked every inch of her booty. Standing up, your aunt looked down at you with an evil grin. You knew she had no idea her new yoga mat toy was her nephew, but seeing this giddy and scatterbrained giantess miles above you look so mischievous at you filled you with fear for whatever was coming next.
"Ewwww I can smell your feet from here mom, please clean those up too! They're dripping!" Charlotte feigned disgust as she pinched her nose. Embarrassed like mad, your aunt took her massive toes and rubbed your tongue between each one before dragging her soles across you, scraping off any grime her sweaty soles had picked up and leaving it behind on you.
"I have never felt better!! Best workout ever thanks to you my little gizmo!" Your aunt exclaimed flashing a coy grin before giving you a couple stamps with her foot for recognition; even such minor taps to here causing more sweat drops to splash across you as they sprinkle off her soaked hair. Being reduced in your aunts eyes as a minor workout "gizmo" you wondered how you would get out of this monolithic torture...
