(Chapter originally written by PhoenixStriker)
For a single, terrifying second, no one in the class responded to Rio's question. It genuinely seemed as if the strict-but-fair woman holding you was about to let your oblivious girlfriend dominate you for the entire class. Thankfully, at what felt like the last second, a cute redhead produced a second Tinex band from her gym bag, and handed it to your gracious girlfriend.
Meekly, Mari smiled at her mom, while stretching her Tinex band. "A-All ready, mom!"
Rio rolled her eyes, but smiled warmly at her daughter. "Alright, then. Let's begin, class. Follow my movements, as I'll start slow but work my way up eventually."
True to her word, Rio started slow, but that wasn't exactly saying much. Putting you behind her back, Rio rammed your body into her sharp shoulder blades, while gripping your head in one hand and feet in the other. Then, she applied pressure to pull you as taut as possible, stretching out her arms. The rest of the class followed suit, letting out contented sighs of a good stretch (whereas you simply mentally cried out as your body was stretched tightly). Rio followed this stretch with a few other back stretches, utilizing your body's properties to enhance the resistance required for each pull.
After the basic warm-ups, Rio started ramping up the intensity. Dropping you to the floor, Rio flexed her dexterous toes and pinched your face between her digits, ramming her big toe into your eye. With her foot holding you down with crushing pressure (and already dripping sweat and flecks of dirt onto your entire being), and then pulled up with all her might, fighting against your body's natural resistance to intense stretching and working out her upper arm strength. The more she pulled up, the more her foot dug into your flesh, her toes grinding into your face mercilessly.
Rio switched to her other foot after that, subjecting you to the same crushing and stretching torture for another few reps, and when she finally stepped off you dared to believe that things might actually improve. Your hopes were horribly wrong, of course, as Rio immediately slammed both feet onto your body instead, and started dropping into squats. You now faced twice the pressure and pain at once, and Rio's squatting motion forced gravity to practically dump every last stray drop of sweat onto your body.
In fact, the next five exercises all involved staying standing atop you, whether it was a bicep curl or a lateral raise. You had to endure the curvaceous, toned woman's full weight for the entire time, your body aching from the strain and your eyes clouding over with beads of sweat and grime. From your one good eye, you looked across the exercise room to Mari, watching her smile happily as she worked through her mom's regiment, having the time of her life.
If only she knew what you were going through, perhaps she'd help. And yet, it seemed as if you were doomed to fulfill Rio's decided punishment for you, yet again suffering for the sake of your girlfriend's mother's misguided attempts at improving your strength and resilience.
After thirty minutes, Rio finally stepped off of you, but right as you thought you might catch a break, the bronzed Brazilian peeled you from the floor, shook some dirt off of you, and then proceeded to slam your face right into her armpit. Your eyes bulged and you silently screamed, but there was no resisting as Rio pressed your face right into the sweat-soaked, stench-laden pits of her underarm area. Instantly, you were drenched in sweat, and your nostrils were smeared with the pungent odor that had grown. You mentally groaned, managing a tiny feeble twitch of defiance. As if in response, Rio only pressed you into her moist flesh harder.
Glancing at her class, Rio motioned for her students to follow suit. "As with all Tinex material, class, it is exceptionally great at soaking up sweat and dirt. No need for a sweat towel when you've got one of these on hand!"
The class laughed, and each took their turn rubbing themselves down from the sweat they'd accumulated with their own Tinex bands. Rio, too, moved from her armpits to scrub down her thighs and legs, feet, stomach, and between her breasts. When she was finished, you were dripping with sweat and smelling quite ripe, yet Rio rather decisively wrung your body dry (causing you to cry out in pain as she twisted and contorted you), and then she dropped you right back to the floor and stomped onto you again.
The exercises continued, and you could only whimper as Rio led her class through everything they'd just done, but twice as fast and twice as many reps. The pain and suffering seemed never-ending, as the athletic woman stomped and crushed you over and over, stretching your body as she worked out her arms and legs, and reducing you to a pitifully quivering, bruised, and dirt-caked shell of your former self. All of your senses were dominated by your girlfriend's mother's sticky sweat and noxious fumes, and your recognizable human features grew more and more smeared away.
Finally, the class neared the end, but a series of cooldown stretches still had to happen. Knowing the Tinex band wouldn't help with that, but keenly aware of Tinex's supportive qualities, Rio simply demonstrated to her class that sitting atop a Tinex band would double as both extra padding and absorbing the sweat of the women's frequently swampy asses. With some embarrassed laughter, all of the class followed Rio's lead, and you could only stare up through a mangled eye and groan as Rio's firm buttocks clapped down onto your body.
Put through far too much abuse in so little a timeframe, you felt your consciousness slipping away. Rio, settling onto the ground, flexed her glutes and wiggled a bit against you, her toned cheeks mashing against your malleable body and forming a booty-shaped imprint in your face. Veritable buckets of sweat soaked through her clothes and into your body, the crushing pressure and stench doubling in assaulting your senses. With a feeble cry you finally passed out, hoping you woke up reformed and in your girlfriend's arms back at her house.

The lesson over, Rio bid her class farewell and stood up from the floor. She was genuinely surprised at how sweat-free her butt felt, having expected a somewhat gross 'popping' sound when she stood. Though, she had to admit, Tinex was certainly a sweat-absorbent product, and a real tiny's flesh even more so. Peeling your mangled form from the ground, Rio quietly thanked her somewhat unwilling participant for doing such a good job in helping her demonstrate the uses of a Tinex band to her class, and also for helping keep her herself clean and fresh.
Folding you up and tossing you into her gym bag, Rio approached her daughter and offered to drive her home. Mari (as was so often the case with her, bless her heart), had temporarily forgotten all about you in the exhaustion of finishing her mom's class. Eagerly accepting her mom's daughter, the two Fuertes women headed back to their house. Once there, Mari headed straight for the downstairs shower, promising her mom that she'd run the laundry with their workout clothes and Tinex bands afterwards. Rio, meanwhile, prepared to head upstairs to shower.
She was stopped, however, by none other than Lauren.
Your mom smiled. "Rio, hey! Ready for dinner?"
Rio clicked her tongue. She'd actually forgotten about Lauren begging for a girl's night out. She managed a smile. "Of course, Lauren. I just need a quick shower to freshen up."
"Ah, no problem!" Lauren waved her hand. "I'll just wait here."
Rio nodded, and set her gym bag down on the floor beside Mari's, which in turn was right beside the laundry room. She then headed upstairs for her shower, making a mental note to retrieve you from her bag before Mari ran the laundry. While she'd bet you'd appreciate the wash, Rio had to figure you'd rather just reform back to normal. She hoped you'd appreciated the strength training experience, and that you'd think twice about sneaking into women's exercise classes in the future.
Meanwhile, back in the hall, your mom absentmindedly scrolled through pictures on her phone, and checked for any new commissions on her fashion design website. This kept her occupied for fifteen minutes or so, but inevitably, your eternally restless mother grew bored. Pacing around like a little child, Lauren's eyes lit up upon noticing her best friend's gym bag. Crossing the room, Lauren opened the bag, winced at the smell, and then smiled.
Her soft hands gripped you, shaking you from your slumber as she pulled you out.
"Ooh! A Tinex band!" Lauren gushed, rubbing her hands on you. You, having been asleep, had no idea what was happening, and you silently screamed at your mother to recognize you. Your mouth was too crushed to reform, and your mom's distracted expression made it clear she didn't know it was you at all.
Hearing the upstairs shower turn off, Lauren jerked her head to the stairwell. "Rio, girl! Can I borrow some of your exercise stuff?"
"Always, Lauren." Rio's distant voice called. "Return it eventually, but keep it however long you need."
"Sweet!" Lauren grinned. "I've been wanting on of these handy little bands!" Bundling you up (and not noticing your feeble twitches of protest), your mom moved to where her purse was resting.
1) Lauren stuffs you into her purse, where it's so tight you're unable to reform, and are taken home with her later that night.
2) Lauren lays you beside her purse, planning to swing by after dinner to grab you. This gives you time to reform after the women leave...except, of course, until Mari comes by minutes later to collect the laundry!
