And of course she doesn't even know

Laylah controlled her breathing to an even keel and not wanting to lose the apparently iron-clad hold on her class's attention, bent down to pick up the kettle-bell in front of her. She looked to the class as she bent forward, her enormous breasts swaying as they hung free. The class was staring with wide eyes and the girl in back was even biting her lip! Laylah raised an eyebrow. Sure, kettle bell was a bit strenuous, but there was no need to look so intimidated, Laylah thought.

She took the circular handle of the 10 pound weight and lifted it, standing with it held straight out in front of her, pointed at the class. They all followed suit like a troop of well-trained soldiers, copying her form exactly. Laylah licked her lips a little, now getting a little excited herself over the obedience of her little flock.

She began a number of kettle exercises, unaware that with each motion her full breasts and erect nipples were on full display, jiggling and swaying this way and that. The class followed along to the letter. On occasion, she'd do something quick and silly. She'd jut her hip out in a sassy way and all 10 participants would follow in kind. She'd kick her foot up in a goofy way and the little peons would repeat without question.

Peons? Okay, maybe Laylah was getting a little too into this level of control... okay maybe a lot into it. As she turned to the black wall behind her and demonstrated proper form for some pretty deep squats, she was grateful she had her pink shorts on because she was fairly sure she'd soaked through her panties a little.

But she wasn't wearing those shorts, and to her class of astonished students, the small wet spot forming on the crotch of her panties was all too apparent... as well as the hole slowly ripping wider at the top of her butt.

Laylah had a rather large rear end. Not absurdly so, but big and round enough to be notable. Her panties, like her bra (rest in peace), had been in her rotation for a long time. The material had thinned from years of wash cycles and were, today, giving way to the strain of her dutiful exercise. As Laylah did squat after squat, turned to the wall, the hole in her pink undergarment grew bigger and bigger, exposing more of her charming little butt crack as she did so.

As she held the kettle bell aloft, her arms beginning to feel hot from the extended strain, she huffed a quick breath and said loudly, "Okay, one more! Extra low, feel that burn in those glutes!"
