A pink top in danger

Mindy grinned broadly. "This is going perfectly. If I can just do the same trick I pulled with the shorts, then the top will be next…. then the underwear will be the last thing left for the blonde! But I need to be quick—Isabel won't hold the handstand forever!"

Moving as quietly as possible, Mindy approached Isabel, who was still breathing deeply, lost in her yoga routine. Mindy carefully reached for the loose pink top, grabbing it from both the front and the back. Slowly, she began to pull it upward, being careful not to let it slip too quickly. If the top moved too suddenly, Isabel would surely notice.

With slow, calculated movements, Mindy managed to slide the top over Isabel’s midriff. Isabel didn’t flinch—she was too focused on her balance. Mindy smirked as she pulled the top further, guiding it past Isabel’s shoulders and over her head.

Finally, the top was off, lying loosely at Isabel's wrists, held only by her hands. But Mindy didn’t have time to celebrate. The teacher’s voice rang out: “Alright class, let's move to the next stage. Lean your feet against the wall, and now, slowly raise your right arm as high as you can. Hold it for 10 seconds, then return to the starting position. Repeat with the left arm. 5, 4, 3, 2, 1, go!”

Mindy didn’t hesitate. As Isabel raised her arm, Mindy slipped the top completely off her wrist, pulling it to the side. By the time Isabel’s hand was back on the floor, her top was gone.

Now, Mindy could finally take in her work. Isabel stood on her hands, her eyes closed, completely unaware of her situation with her eyes tightly closed and a satisfied expression on her lips. In just a sports bra and panties, she was in stark contrast to the other students, who were all still fully dressed in their workout gear. Her private parts and her big butt were covered only by a pair of white panties. The only piece of clothing on her upper body was a white bra. This one had probably been bought without being quite sure whether it was meant to be sexy and sporty in the first place. On the one hand, it had wide straps and obviously gave stable support for what it was meant to conceal. On the other hand, for a sports bra, it gave a clear indication of cleavage. It also offered two ways to open it, the zipper on the front, as well as on the back. This pleased Mindy extraordinarily, as a possible sports bra had been a concern here, for how could she have removed it without being noticed? But two zippers are also two points of attack. "Surely these zippers are an offer to a very specific person to free her melons," Mindy mused. "But I don't think it ever occurred to her that these zippers might also offer other people the opportunity to break through their protection. And it's certainly not meant for a room full of young people," Mindy gloated thievishly.

Isabel had no idea what had happened. She was fully immersed in her yoga practice, oblivious to the fact that she was now almost entirely undressed in a room full of people.

Would she notice her situation soon? Or would someone else in the class catch on first? Or was Mindy not done yet?
