...the instructor told them to stand up straight and finish the forward fold (alternative version)

The instructor then asked everyone to stand up and hold their elbows as they rose from the forward bend. Isabel took this as her cue to pull up her shorts, but there was a complication: Mindy had grabbed hold of them! The spandex shorts had always felt a bit tight during workouts, as did the boyshorts she wore underneath. In her haste to pull up the shorts, Isabel didn’t notice that the fabric she grasped was much thinner than her shorts. The snug fit of her clothes made her think everything was in place. Isabel pulled her underwear up, thinking she was covering herself, while Mindy took advantage of the moment to tug Isabel’s shorts all the way down to her ankles!

Mindy quickly glanced around to see if anyone had noticed. She was both relieved and pleasantly surprised that she’d managed to get this far without being caught—none of the other girls in the class, nor the instructor, had any idea what had just happened. Maybe it was the fact that Isabel’s white underwear blended with her shorts, making it seem like she was still fully dressed.

Isabel’s panic faded, giving way to a calm sense of relief. Just moments ago, she’d been flashing half her rear to the room, but now everything seemed fine again. In the rush of adrenaline, she hadn’t realized she’d only pulled up her underwear and didn’t notice that her shorts were still bunched around her ankles.

'Hopefully everything’s fixed now, and I can finally focus on the class,' Isabel thought, standing there as the instructor guided them into the next pose. Much to her relief, the instructor had them transition into a different move. Isabel tilted her head back, stretched her arms straight toward the ceiling, and lifted her feet so only her toes touched the ground.

Meanwhile, Mindy kept her eyes more on Isabel than on the instructor, eagerly waiting for another opportunity to undress her even further.
