Finally, everyone had taken their seats, and Fariha plopped down as well. One of the students closed the door to the class room, Fariha turned on the ambient mood music she always used in her classes, and she began leading her students through some simple arm exercises. She always kept her classes zen-like and meditative, which was the main draw for the ladies who participated. Mari poked fun at her for leading such tame classes compared to her personality, but the simple truth was that Fariha was a girl who lived like a bubbling beaker of energy. When it reached the brim she needed to frantically let herself loose to lower the beaker, then she could rest for a while. It's why she'd taken to pranking, using it as an outlet for her excess of energy, which in turn gave her more time to chill and relax between pranks.
After the arm exercises, Fariha moved onto the part she was really excited for, which were the leg exercises. Spreading her legs into a wide perfect split, Fariha motioned for her students to do the same (to the best of their abilities). Only Annika was truly able to match Fariha, which was impressive given the heft of the blonde's rear, and how shapely and toned her buttocks and thighs were. She was surprisingly flexible, and the sight of the blonde's perky booty pulled taut as she stretched gave Fariha a brilliant new idea.
"Annika, almost perfect form. You just need to slide forward a little." Fariha explained to the blonde.
Annika blinked. "O-Oh, really? Okay."
Annika then dragged her ass forward along her mat, trying to match what her instructor had described.
Underneath that firm booty, you let out another tortured yell as your oblivious tormentor once more ground you into paste with her gigantic glute. You were less man and more mangled sticker at this point, her ass cheek having decimated your body and left you firmly glued to the fabric of her shorts. And of course, even after her split, you were still firmly slammed down into the mat and not given a second of reprieve or fresh air. Speaking of air, it was beginning to grow stale, and a faint stench was growing stronger, not to mention the rapid slickening of Annika's shorts due to her booty sweat.
Fariha pursued her lips. "Ooh, wait. Back up a little now, Annika."
Annika nodded in acknowledgment, sliding her ass back again.
"Um...forward just a tiny bit."
Annika did so.
And over and over the two of them went, over ten times of Fariha asking for minor corrections and pure-hearted Annika obliging without complaint, eager to please her instructor and having no idea of the hell she was subjecting you to the entire time. For that matter, Annika hardly even knew you existed, and certainly didn't know that her precious instructor had fibbed about rescuing you, nor that you still adorned her right butt cheek. She truly believed Fariha was just fastidiously trying to correct her posture, and Annika very much valued getting a good and balanced workout, which included proper posture.
So she just kept obediently grinding her ass along the mat, all while you suffered beneath her. With her firm doughy buttock above you, and the unyielding mat from below, you didn't stand a snowball's chance in hell at weathering the storm of booty-based beating. Your squishy body contorted more and more with each grinding motion, your malleable self smearing away into nothingness beneath Annika's rump. Your mouth was ripped open wider and wider from the force, and thusly made to suck in even more of Annika's increasing output of rank booty sweat, while the rest of your body became a mangled and mashed mess that started binding with the very fibers of the blonde's tortured compression shorts. In precious little time, you'd become practically baked into the fabric, and would need true outside assistance to not find yourself forever accompanying Annika on her gym outings for all time.
To avoid the rest of her students catching on, Fariha finally brought her fun to a close, but her fount of mischievous ideas had far from run out. No, she was only just getting started, the girl having gone nearly a week since last seriously pranking you, and her figurative little beaker of energy was still broiling over with a desperate need to release.
"Okay, ladies, we're gonna do a little booty lifting." Fariha explained. "Everyone, lean forward, place your hands on the floor, and try your best to heft those cute booties into the air! Hold for a second, then let those buns plop right back down, got it? Twenty reps, but feel free to take it nice and slow. This is yoga, after all, so maintain your breathing and hone your core."
Fariha demonstrated, expertly raising her own far larger than average buttocks off the mat, holding herself up for three seconds, then plopping back down. As one, the rest of the ladies started to follow suit. Some of the students had trouble, but all of them dedicated themselves to performing the twenty reps that Fariha had asked for, not wanting to let their instructor down.
As Fariha anticipated, Annika was not only the most skilled at performing the motion, but also the one who performed it the most enthusiastically. The clapping sound of her ass cheeks smacking back onto her mat after each rep reverberated through the class room, making a few of the other ladies giggle. No one giggled harder than Fariha, though not a single soul in the room knew exactly what it was that had tickled the pretty Indian girl's funny bone.
You knew, of course, but it wasn't as if you could do a thing about it. You were nothing more than the plaything to Annika's booty now, far beyond the point of being able to save yourself from the blonde's bodacious buttock. As Annika raised herself up, you were given tantalizing scant seconds of fresh air before she'd pound you back down again, dropping her full hefty weight upon you in a repeated crushing motion, her ass flesh rippling along your body and an extra dose of sweat flooding into your mouth. And then she'd raised up and repeat the process all over again, like some sort of accursed and miserable amusement park ride you desperately wanted off from, and yet your only possible salvation was the girl giggling the loudest at your misery.
Annika reached rep nineteen, hoisted herself up on slightly shaky arms, and then fell back down onto her mat having completed all twenty reps. Her ass made a bit of a squelching sound as she landed, a swamp of sweat having formed in the buttcheek-shaped crater in her mat. Annika winced at the distasteful sensation, and hastily shimmied in her sweat, willing her shorts to mop up the sweat and remove the irritation. To her surprise and delight, they seemingly did just that, soaking up all of the sweat and rendered her mat and her ass dry once more.
Of course, it wasn't a miracle mat doing that, but you yourself. Like all tinies, your DNA was superhuman when it came to being absorbent, and though you tried to resist and fight, your body dutifully moped up Annika's booty sweat as she ground you into her rank, earthen-musky-smelling mat. Your body greedily sucked up all of the sweat and brought it into your own body, filling you with disgust at both the viscous liquid soaking into you, and also at how utterly incapable you were of stopping this from happening. You were on the roller coast that was Fariha's prank, and it only ended when she wanted it to...which almost never seemed to happen soon enough with her.
Fariha watched with rapt amusement as Annika skootched her derriere back and forth moping up the sweat on her mat, and she eagerly wracked her brain for a way to keep this prank continuing while also giving her students a good workout. You, after all, were her favorite tiny in the entire world to prank and play with, and she was fully prepared to milk this for all it was worth knowing it'd be a week or more before she could get you to herself like this again.
Smiling suddenly, Fariha thought of what to do next.
1) Fariha decides to make today's class a Hot Yoga session, cranking up the temperature in the room as high as it can go, and leading everyone sweating buckets, particularly sweat-prone Annika.
2) Fariha makes every other yoga stretch and exercise for the entire class session focused around butt movements and repeated booty squashings, and an unaware Annika really puts you through the wringer.
3) Before Fariha can make her move, someone actually spots your smeared body on Annika's booty and points you out, leading to Annika freeing you. Fariha bluffs her way out of taking blame, but now has to find something new to do with you as the class resumes.
