She continues the class without her tights

"Wait!" Mackenzie said, halting the various women getting ready to leave. She gulped nervously, already knowing what she was about to say was a bad idea. But she said it anyway. "The class will continue as planned. Please get ready for our next pose."

The departing women headed back to their mats, now seemingly content that they'd still be able to practice yoga.

"Now we'll do the Tree pose," Mackenzie said. "This focuses primarily on balance. Watch me," she said, as if there was a single pair of eyes in the room not already watching her intently.

Mackenzie brought her palms together and pointed her fingers upward. Then, she slowly pulled her right leg up, bending her knee and resting the bottom of her foot against her left thigh. As the women began trying to emulate her example. the redhead was silently grateful that the next pose in the routine had been one where she wasn't really embarrassing herself too much. Sure, her panties were on full display, but at least she wasn't in a more... compromising pose. She held the position for a minute, then instructed the class to switch to the other leg.

The next pose, however, was one Mackenzie was utterly dreading. The pantsless woman would have given anything to spend the rest of the class assuming easy poses that wouldn't draw more attention to her underdressed state. But just like everything else at the gym, Stefan had complete control over the assigned yoga routine. If he found out Mackenzie had been doing anything different, anything at all, well she might very well face some of the very same consequences that had made her decide to continue teaching the class her current state of undress. And so, the redhead prepared to model five repetitions of Downward Facing Dog into Upward Facing Dog.

"A-alright," she said, unable to hide her nervousness, "now w-watch me."

Mackenzie bent over and placed both her hands on the mat, spread wide. Then, she slowly lowered her torso, raising her butt while keeping her arms and legs straight, putting her panties on full display for the class via the mirror behind her. She was supposed to hold the pose for 10 full seconds, but only made it to a mental count of 5 before she couldn't stand it any more. Mackenzie then began dropping her hips and raising her torso until her legs were flat on the mat, then she arched her back and looked up at the ceiling. She held this pose for the full 10 seconds. One down, four to go.

Mackenzie shifted back into Downward Facing Dog, feeling something was slightly off. It almost felt like her panties had shifted slightly. Brushing it off, the embarrassed instructor reverted to Upward Facing Dog, once again dragging her hips along the mat. When Mackenzie raised her ass yet again for the third rep, she was certain that something had changed. It felt like her panties were sitting lower on her hips than before! That time, as she brought her butt down and her head up, Mackenzie felt it. When she slid her hips along the mat, the friction was dragging her panties slightly down her body! The redhead resolved not to lower her hips quite so much for the last two reps.

However, when Mackenzie raised her ass in the air for the fourth rep, disaster struck. Her panties had already been lowered too much and were now more than halfway down her curvaceous ass. Even as Mackenzie remained perfectly still, the tight underwear was slowly sliding further and further down the curve of her butt. And then, suddenly, it hit the point of no return. It cleared her ass and began rapidly sliding down Mackenzie's thighs, leaving Mackenzie completely bare-assed in front of the class.

Arms shaking, Mackenzie quickly began raising her torso, dropping her ass lower but not out of sight. The whole room was still treated to the unobstructed sight of the yoga instructor's beautiful behind in the mirror as the red-faced woman cringed and closed her eyes. Mackenzie held the humiliating pose for a full 5 seconds, as long as she could stand, before dropping her torso down again. And then she remembered that she had one last rep to go. So once again, Mackenzie raised her hips and bared her ass for all to see. Her pink underwear pooled around her ankles. She could hear giggles and murmurs from the women, alerting her that everyone knew she had managed to slip out of her panties.

"AndnowdropdownintoChild'spose!" Mackenzie said hurriedly as she brought her ass down as swiftly as possible. She sat back, letting her butt rest on her heels and pressing her knees and chest down into the mat, her arms still outstretched in front of her. "And hold."

With her face pressed down into the cool mat, Mackenzie took a few long moments to try and collect herself. That had been absolutely humiliating, but at least it was over. And the next pose wasn't going to be nearly as bad once she had her panties back on. Without raising her head, Mackenzie brought one hand to her feet and began feeling around for her underwear. In her rush to hide her exposed chest, she'd accidentally pulled her feet forward a few inches, slipping them out of the fallen panties. But as she blindly felt around, she didn't feel any fabric. She couldn't have moved her feet that much, could she?

Mackenzie tentatively craned her head sideways and what she saw made her blood run cold. The mat beside her was completely empty. She checked her other side and found it empty as well. Her panties were nowhere to be seen. She began frantically looking around, but saw no sign of the pink undergarments. Had someone taken them? They must have! But as she looked around, Mackenzie saw all the women had their heads down in Child's pose. Had one of them managed to take the panties, hide them somewhere, and get into position before Mackenzie had looked up? It didn't seem likely. But what other explanation was there? Blushing deeply, Mackenzie nervously got to her feet, covering her pussy with her hands.

"Y-you can get up now," she said to the class. As each of the women rose, they visibly registered a look of surprise at Mackenzie's bottomlessness. The half-naked woman felt almost overcome with embarrassment. She wanted to flee the room, but then what would she do? Instead, she asked, "And, um, has anyone... seen my panties?"

That got a round of chuckles out of her staring audience.

"Anyone? Like at all?" she asked, trying to keep the desperation out of her voice. "Or, or maybe picked them up by accident?"

"What's the next pose?" a woman in the front row replied instead.

"N-next... Uh, well I can't really teach the class without my underwear!" Mackenzie said. "If you want the class to continue I need to get my panties back!"

"Nonsense!" a middle aged woman on the far side of the room said. "You just did those last poses without undies on, and we followed you just fine!" This brought murmurs of agreement from the room.

"Ladies, c'mon... Please..." Mackenzie pleaded.

"Are you gonna show us what comes next or am I going to have to complain to the owner?" the first woman said. Apparently she had realized why Mackenzie had continued teaching the class after the destruction of her bra.

Mackenzie's mind was reeling, but as she glanced around the room she saw no sympathetic faces. Everyone seemed either indifferent to, intrigued with, or downright amused by Mackenzie's plight . The redhead glanced at the clock. 8:17. That whole ordeal had only lasted 9 minutes! And there were still 33 minutes of class left... Mackenzie, with little other choice, turned back to face the class.

"The... the next pose is the Warrior II pose," she found herself saying, surprising even herself. Could she really continue teaching this class without bottoms?! "Your legs are in similar positions to Warrior I," she said, demonstrating the stance, making sure to keep her crotch covered, "b-but this time.... your arms will be..." Mackenzie took a deep breath, bracing herself for what she was about to do. Then, she slowly extended her arms out to her sides, letting her pussy come directly into sight. "Out to the sides."
