Some slippage

Mackenzie felt the pants slip further, millimeter by millimeter, down her body. She started panicking, desperately trying to think of a way to grab her pants, but with both her arms completely full there was just no way. She was still behind Scott luckily, so he had no idea about her impending nudity. But they were still in the middle of a hallway and anyone could walk by!

Mackenzie's heart hammered in her chest as she felt the fabric suddenly increase the speed of its descent. The pants fluttered to the ground around her ankles, stopping the redhead in place, now completely bottomless. In a flurry of movement, Mackenzie bent down and dropped both medicine balls before grabbing the waistband of the pants. She was dully aware that Scott was turning around, likely alerted by the sound of the dropped balls. With a whoosh, Mackenzie yanked her pants up as high on her hips as she could manage, just as Scott finished turning towards her.

"Whoops!" Mackenzie said, sounding a little out of breath, "Dropped them!"

"No worries." Scott replied with a slightly confused expression before turning back around, "These puppies are super durable."

Slightly delirious, Mackenzie shivered slightly at how close she'd come to exposing herself just there. She bent down and hastily regrabbed the medicine balls and hugged them to her chest before resuming walking after Scott.

I'm not out of the woods yet, Mackenzie reminded herself. These pants will fall again if we don't get there soon.

Sure enough, she could already feel the slippage beginning again.

Stay calm. I'll just pretend to drop the balls again. It'll be fine, I just have to stay ready. Don't get distracted. Ignore the cold tiles on your feet. Ignore the smooth leather on your nipples. Ignore the... Wait WHAT?!

In horror, Mackenzie looked down at her chest and saw that she was hugging the medicine balls up against her bare breasts. Her tank top was gone!

What the fuck?! she thought, Where the hell did my shirt go?!

Still walking, Mackenzie looked behind her and down the hall she saw the grey fabric of the tank top in a small heap on the ground in the middle of the hallway. Just before she regrabbed the balls, it had slid off both her shoulders and all the way off her body!

What do I do, what do I do?!? thought the flabbergasted Mackenzie as she still followed behind Scott.

The medicine balls covered her breasts for now, but when she put them down Mackenzie would be completely exposed!

"Here we are!" Scott said as he walked into an open doorway with Mackenzie not far behind.

They seemed to be in some large storage room with various equipment and a few desks covered with papers. Scott walked over to a corner and let all three balls drop in a pile.

"You can just dump those anywhere." he said before turning back around to face Mackenzie. "The lost and found's over..."

Scott trailed off and got a puzzled look on his face. Though Mackenzie's breasts were covered, just holding a few balls in front of her chest didn't give her the illusion of wearing a shirt, and it was pretty obvious she was topless behind them.

"Uh..." Scott muttered, not sure what to say.

Mackenzie was wracking her brain to try and think of some excuse or distraction she could use to get out of the situation. She was beyond ****!
