She continues the class without her sports bra

"Wait!" Mackenzie said, halting the various men 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 grinning men quickly headed back to their mats, now seemingly more eager than before 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 men hesitantly began trying to emulate her example. the redhead was silently grateful that the next pose in the routine had been one where she didn't need to expose herself. As long as she kept her hands tightly pressed against her chest, she could keep her boobs contained within her tank top. 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 braless woman would have given anything to spend the rest of the class assuming easy poses that wouldn't risk showing off her breasts. 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. As she knew would happen, her loose shirt began slipping down, moving up her torso, stopping slightly as it bunched up around her breasts. 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, allowing her shirt to partially drop back down, covering some of her stomach again. One down, four to go.

Mackenzie shifted back into Downward Facing Dog, acutely aware of the twentyish gazes laser-focused on her body. This time, her shirt fell farther, settling around her armpits. The embarrassed instructor reverted to Upward Facing Dog, mentally urging her shirt to drop down as quickly as possible. It obliged, slipping down to the bottom of her breasts, but not before exposing Mackenzie's pink nubs to the class for a few moments. The third rep sent her shirt even farther up Mackenzie's body, so when she brought her head up, the shirt only slid down to the top of Mackenzie's chest, leaving her boobs completely out in the open! Suppressing a squeak of surprise and embarrassment, she began shaking her torso back and forth, hoping to make the shirt drop further. But instead, Mackenzie only succeeded in causing her large breasts to jiggle and sway for her gather audience.

Changing tactics, the redhead dropped back down, at least partially shielding her breasts from view. But this time, Mackenzie's shirt was too far gone. Before she knew it, her tank top slipped over her head and plummeted to the mat, pooling around her wrists. This time, Mackenzie did emit a short squeak of shock. Now she was topless! And she wasn't done yet...

Arms shaking, Mackenzie slowly began raising her bare torso. More than a few gasps were heard from the assembled men as Mackenzie begrudgingly thrust her chest forward for them all to see. The whole room was treated to the unobstructed sight of the yoga instructor's beautiful breasts 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 down again. And then she remembered that she had one last rep to go. So once again, Mackenzie raised her chest and bared her boobs for all to see. Her nipples, clearly hard in the cool air, completed the lovely picture. Mackenzie was closing her eyes again, attempting to diminish her embarrassment. But after seeing her do so the previous rep, a couple clever young men were ready. They had their phones out and quickly took several pictures of the topless redhead who was none the wiser.

"AndnowdropdownintoChild'spose!" Mackenzie said hurriedly as she brought her chest 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 shirt back on. Without raising her head, Mackenzie began feeling around for her shirt. In her rush to hide her exposed chest, she'd accidentally pulled her hands back a few inches, slipping them out of the tank top. But as she blindly felt around, she didn't feel any fabric. She couldn't have moved her hands that much, could she?

Mackenzie tentatively craned her head up and what she saw made her blood run cold. The mat before her was completely empty. Her shirt was nowhere to be seen. She began frantically looking around, but saw no sign of the white tank top. Had someone taken it? They must have! But as she looked around, Mackenzie saw all the men had their heads down in Child's pose. Had one of them managed to take the shirt, hide it 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, cradling her breasts with her hands.

"Y-you can get up now," she said to the class. As each of the men rose, they visibly registered a look of surprise at Mackenzie's toplessness. 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 shirt?"

That got a few chuckles out of her leering audience.

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

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

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

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

"Guys, 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 man said. Apparently he 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. No one was going to speak up and deprive the rest of the class of a busty topless yoga instructor. 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 a top?! "Your legs are in similar positions to Warrior I," she said, demonstrating the stance, "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 breasts drop back into sight. "Out to the sides."
