Stay, hide in the steam

Mackenzie bit her lip. The other two hadn't noticed her yet, though she wondered... would they? One was fixated on his job, while the other had his stamina taxed to his limits. In the thick steam, they were shapes with voices. Which meant that, at most, she would be just as hard to see, even without their distractions. If she stayed as quiet as a sheep, she'd have the room to herself again.

"And I gotta exercise like this every day?"

"Well it depends on what you're trying to do. You don't have to do this every day for healthy living, so long as you stay active. Two or three times a week can be just fine." The trainer added. "It's important to work at your pace."

The towel-clad redhead held her breath. From what she could tell, they hadn't looked her way yet. Still, Mackenzie started to scoot her way down the bench, putting a little more distance between herself and the two guests. However, every single micromovement she made, tugged against the feeble knot that held her towel together.

"What's the point of the steam room?"

"It's important to rest your body after an intense workout. This helps it heal better so it can take on a more challenging workout next time." The trainer stood up. "Here, let me turn up the steam a little." He approached the door to the steam room, and Mackenzie heard a clicking noise. There was a hum reverberating through the walls, and more steam began pouring into the room.

Now the cloudy atmosphere heated up, thick with oppressive humidity. And as more of the fog swelled in, the two blobs on the other side faded from Mackenzie's view. She couldn't see them at all.

"There we go, this will help us relax some more," explained the trainer, returning to his seat.

Mackenzie took a breath. The thicker cover worked to her advantage. She rose to her feet and moved even further down the bench, as far as she could go from them. However, between the relentless **** of the humidity and her brief movement, the knot of the now heavy towel had **** but to surrender, slipping apart, and letting the towel slide down the naked red-heads body.

When Mackenzie's uncovered body felt the bench, her eyes went wide. Frantic hands clamored her body, clawing at herself in search of her precious towel. It was gone, and out of sight in the dense clouds of warm steam.

"N-no way," she whispered to herself.
