(Chapter originally written by PhoenixStriker)
The realization hit you like a ton of bricks. You totally could sneak right in, couldn't you? It's not like anyone would notice your one-inch-tall self sneaking inside, especially as tinies like you weren't expected in the class anyway! No one would be paying attention to where they were walking or sitting, right? Which, theoretically, could actually be quite dangerous, but you shook off that thought. No matter what Rio had said, you were going to join Mari's class!
Having decided on your course of action, your eyes widened as, surprisingly enough, one of the Focused Fitness employees happened to be striding right towards the table Mari had dropped you on, seemingly walking in the direction closest to the private room where Rio's class was. Steeling yourself, you waited for the employee to cross close enough before you flung yourself from the table, splayed your arms, and collided with the women's slick joggers. Just barely managing to hook an arm into her pocket to steady yourself, you clung to her like an unseen passenger as she kept on walking.
When she passed close enough to the class door, you gulped and tossed yourself from her, flailing your arms as you raced to the ground and splattered out like a little blob. The woman walked on, oblivious to her status as your personal taxi, and you quickly reformed as fast as you could. It was a good thing too, because no sooner had you popped back to normal then two eager women stomped right by you, heading into Rio's room. You barely avoiding being decimated under their soles. It was a little harrowing, and temporarily made you reconsider the merits of this plan, but you pressed on anyway.
Pumping your legs, you dashed into the room, leaping over the small doorstop bump and tumbling into the exercise room proper. You then frantically scrambled along the floor on your hands and knees, scrabbling around like a lunatic as three more women piled into the room, laughing and smiling at each other as their house-sized feet stomped all around you. By the time you had enough of a reprieve to get your bearings and catch your breath, you practically felt like you'd had a full workout already. You still took a second to take in the room and its denizens.
Rio's classroom was a fairly standard exercise room, all things considered. The room was arranged with rows of freshly washed yoga mats lined up, five to a row and four rows deep, for a total of twenty mats. The twenty lined up mats faced a single mat, which was presumably Rio's. Two entire walls were covered with full-body mirrors to aid in matching correct forms and posture. Against one wall was a few boxes full of miscellaneous exercise equipment and supplies, along with a healthy amount of free water bottles.
Perhaps most startling were the sheer number of women crammed into the room. Sure, you'd expected something like this given the twenty provided mats, but actually seeing nearly twenty towering, revealingly-dressed, toned and curvy giantesses was something else entirely. Yet again, you started to doubt your plan, but as your eyes locked onto Mari (who was standing right in the front row across from where her mom would be), you renewed your courage. Your end goal was in sight, and you'd be joining Mari in this class if it killed you.
You took one step towards Mari...and were then instantly demolished under a heavy, bronzed sole.
Your squishy body gave out instantly, flattening out under the mysterious and unexpected woman's foot. You'd only had time to twist as you were squished, leaving your mangled body staring straight up into the dirt-flecked skin of the woman's sole. You mentally groaned and tried to squirm free, only to find to your surprise that the woman herself pulled her foot back a second later. You were even more surprised to find the woman spread her toes and stare right down at you, clearly spotting you. You were further flummoxed upon recognizing the woman as Rio!
For a second, your heart leapt for joy, as you'd been briefly horrified about the possibility of spending a lengthy exercise class glued to an unaware woman's sole. But, then you remembered that you'd snuck in here specifically against Rio's orders, and from the disappointed scowl on the titanic woman's face, you knew that you were deeply screwed. Rio was a pretty emotionally calm person, infrequently demonstrating strong anger or joy. But, when Rio was ticked off, she could be legendarily terrifying.
As it was, Rio's scowl deepened, and her toes closed back around you, crushing your head into a blob between two of her dexterous digits. You grimaced as your girlfriend's mother's toes closed around you, and the pain was renewed as Rio resumed walking, clearly carrying you away somewhere. With each step, your body was rattled and slammed, your head further squeezing itself into the slightly damp crevice between Rio's toes. You mentally gagged, but even your strongest attempts to pull away now couldn't fight Rio's strength.
Finally, your captor stopped walking, and you felt a dizzying sense of weightlessness as Rio lifted her foot up. You then felt her fingernail stab into your back and rip your body free from her toes. After a second, you were deposited in her awaiting palm, but before you could even think of reforming and begging for forgiveness, Rio closed her palm around you tightly, squashing you again and keeping you flat.
"You're unbelievable, Matt." Rio sighed, her tone even but a clear hint of annoyance in her voice. The dark-haired Brazilian cast a glance over her shoulder, towards where the final few members of her class were still filling into the room. None of her students had seen her grab you from the floor, nor carry you into the corner of the room. Rio turned back to you. "I gave a single rule about this class, and you've broken it in minutes. I mean, really, Matt? Mari would've been done after just about two hours. You couldn't wait that long?"
You tried to groan, but only a feeble choking sound came out before Rio clenched her fist even tighter, crushing your lungs.
Rio rolled her eyes. "It's lucky for you that I know you well as a person, Matt. If I was any other instructor at this gym, I'd think you were a little pervert trying to spy on my students. There's no telling what I'd be justified in doing to you then. Thankfully, I know you're just trying to spend time with Mari. It would be flattering, if your actions didn't fly in the face of my rules, and also demonstrate a clear lack of intelligence and foresight. I mean...truly, what was your plan?"
You couldn't respond, of course, but everything Rio said was true. What had you been thinking?
Rio, for some reason, started to smush you between both palms, while simultaneously picking at your squishy body with her fingernail. "You can call me stern, or even merciless, but I like to pride myself on being fair. Act responsible, and I'll treat anyone like an adult. Act foolishly, and I expect people to take their discipline and punishment, and learn from it all." With a flick of her wrist, Rio ripped your clothes clean off, leaving you naked in her hands. As she flicked your tattered clothes into the trash with one hand, she started pulling and stretching you with the other.
Pulling you into a long rectangular shape roughly two feet long and four inches wide, Rio continued. "I'll admit, Matt, that it is exceptionally easy to punish affected guys like you. Not only does your stretchiness make it simple to craft a suitable punishment, but it also serves as additional strength training. You'll grow stronger, and learn your lesson never to act foolishly again." Rio licked her thumb and took a minute to wipe at your face and exposed private parts, smearing your recognizable features into a simple tan blur. "So, I hope one day you'll even thank me for this."
Throwing you over her shoulder, Rio turned back to her class just as the twentieth student arrived and closed the door. Clearing her throat, Rio claimed her students' attention.
"Good morning, everyone." Rio began. "I know this is a class you've all been looking forward to. Simple stretches, poses, and aerobics are nice, but the assistance of a tool cannot be overlooked. Thankfully, due to advances in exercise equipment, Tinex Bands are now commonly available. I hope you all brought your own."
As one, every student retrieved stretchy tan rectangles the exact shape as you, holding them out towards Rio for her approval. Upon hearing Rio's words, your heart sank. She was going to use you as an exercise band? That was your punishment? To be stretched, squished, and used in whatever way she had planned, all while the rest of her class had no idea there was a tiny being disciplined in their midst?
Rio smiled at her class. "Good, you all look like you bought the genuine articles. Tinex is heavy-duty material, but it can really take a beating, so we won't be holding back this class."
Meekly, Mari raised her hand, drawing Rio's eyes. "I...uh...didn't bring one." Your girlfriend said sheepishly.
Rio smiled coyly. "And how would you have known to do so, daughter of mine?" The class laughed, lightly ribbing Mari, who started blushing. Rio looked at her students. "Anyone with a Tinex Band they could spare? It's critical for today's class."
The other students gazed between themselves, and as Rio's question hung in the air, you couldn't help but feel a strong sense of foreboding.
What happens next?
1) Another student has a spare for Mari, so class begins with Rio using you.
2) No one has any spares, so Rio gives you to Mari. Mari uses you the entire class, oblivious to your true nature.
3) No one has any spares, so Rio gives you to Mari. Somehow, Mari recognizes you, but not wanting to make her mom mad, she has no choice but to use you anyway.
