She gets roped into a more public workout than she'd planned.

Brandi's plan was to go, lift some weights for an hour or so, skip her usual cardio and change clothes with as little personal interaction as possible.

Unfortunately, her friend Angela saw her as soon as she came in.

"Brandi, thank god you're here! I have a family emergency, can you cover my kettlebell class today? I know you don't technically work here yet, but you've taken it a bunch of times and no one else is available right now...wait is that what you're wearing."

"Yeah, um...uh...it's laundry day."

"You're braver than I am, girlfriend! So will you do it? I'll totally wave your membership fee for the whole month."

"Well, okay. Anything to help a friend," she said.

"Oh thanks, you're a lifesaver. You start in 5 minutes."

That was barely enough time for Brandi to put her gym bag in a locker and fill up her water bottle before she was standing in front of a group of about 6 men and 5 women while dressed in a tank top made for someone half her size and a pair of transparent black nylons that showed of her tiny thong. She was blushing from head to foot as she introduced herself.

"Hi, I'm Brandi. I'm subbing for Angela today. I see you've already picked out a kettlebell, so I'll just put some music on and we'll get started."

They started with some basic kettlebell swings, during which Brandi obligingly turned sideways so they could see the way she hinged at the hip, even though that meant every one was pretty much staring at her ass. That's okay, she thought, she'd worked hard for that ass.

Unfortunately, she was so distracted by her form that she didn't notice that her swinging arms had brought her tiny tank-top up, exposing a sizable landscape of underboob.

Brandi remained oblivious to how much of her boobs were showing while she took the group through 20 minutes of non-stop kettlebell exercises. She didn't even think anything of it when one of the men in the class asked to turn around during the squat thrusts "so he could see what proper form looks like."

She was working up a sweat and really starting to enjoy herself when she noticed that they were running out of time. She decided to start their cool down with some halos.

"Okay, everybody. Take your kettlebell in both hands, and move it in a slow circle around your head, really focus on shoulder mobility, EEEP!"

As she demonstrated the movement with both arms above her head, the tank top slipped the final few inches over her nipples, exposing both of her breasts to the entire exercise class.

She set the weight down as quickly as possible, tugged her shirt down and rushed out of the class to the locker room.

She chugged her water and took a few deep breaths before finally stripping off her ridiculous workout clothes and taking a shower. As she thought about all those eyes on her, she absentmindedly rubbed her nipples a little and worked down to her clit, reveling in the taboo excitement of public exposure.

She had to stop when she heard the door to the locker open. She hurriedly dried off and went to change into what ever outfit Amy had picked out for her to wear to class.
