No one, but not for the reason you think

Mackenzie's heart skipped a beat. As she flipped around, her dripping wet crimson hair swung around and slapped her right in the face, blocking her vision of whoever entered. At the same time, a sudden draft wafted over her lower half!

One side of her towel was hooked on the little door latch of the toilet stall that she was standing in. As she spun around, she held tight on the knot at the top of her towel, but, since one corner of her towel wanted to stay still, that meant the bottom half of it unraveled open like a burrito being purposely unwrapped combined with the parting of curtains at a very lewd play. Every part of Mackenzie's body from the sternum down was unveiled to the world. Her tight tummy... her pale legs... even her bright red triangular bush and pink pussy lips were turned right toward the noise and presented in all their glory. Her skin dripped and glistened in the bright light of the bathroom, since she was straight out of the shower and hadn't had much time to dry off at all.

Mackenzie squeaked and slapped her left hand over her crotch while trying to tug the snagged towel free with her right. The dainty hand between her legs couldn't quite cover all of the thick curly red hair peaking out from behind it. She was careful not to tug too hard or she might unravel the top part of the towel that was still somehow managing to stay around her chest, but that wasn't exactly something you could fully prevent with both hands occupied.

Since both her hands had important jobs, the sopping wet hair plastered over her eyes was there to stay, and therefore she continued to be unable to see. She wanted to shut the toilet stall door, but couldn't exactly do that either with her towel stuck in the door latch.

And so, totally blind and frantically (but carefully) yanking at her stuck towel, with her bottom half exposed to whatever stranger just entered the bathroom, Mackenzie cringed as this moment stretched on for a painfully long amount of time.

It got exponentially more painful a few seconds later when her towel almost came unraveled and then she gave up yanking it and instead held it together with that hand. That's when the obvious solution dawned on her. Her towel was trapped, sure, but since it was just one of the bottom corners, all it took to become fully covered again was one reverse twirl to wrap it back around herself.

One quick pirouette later and Mackenzie's towel was wrapped around her again, albeit with her hip jammed a bit uncomfortably close to the bathroom stall doorway, but she was at least fully covered once again.

Mackenzie wracked her mind, trying to think up how she could possibly explain why she just gave this person the world's naughtiest curtsy. She knew how intentional it probably looked. If Mackenzie herself walked into a bathroom and some stranger did a twirl, unveiled their private parts to her, and then 'failed' to unstuck their towel for over thirty seconds, she'd suspect them of being a flashing pervert, too!

Mackenzie used her now free hands to push the hair out of her eyes and gave her best casual nonchalant giggle as if this was the funniest little accident.

"I can explain..." started Mackenzie.
