One of her coworkers sees her discarded clothes... and underwear.

Any hope Mackenzie once had of remaining undiscovered was quickly getting dashed aside. The girls were insistent on joining Mackenzie, or making her join them, whatever the group decided to do, and the water jet between her legs felt more powerful than ever. Mackenzie bit her lip, striving to contain herself despite the burning sensation in her groin. It was taking considerable effort just to keep acting casual, and unfortunately it seemed she needed all her wits to make her stubborn coworkers go away!

Sophie smiled too, and started whispering back to Anne. If there was any doubt before, it was gone now. They knew. They were just trying to decide what they should do about it. Mackenzie felt more trapped than ever before. Whatever mischief they were planning, she had no real choice but to accept (and knowing those two, they definitely had some sort of mischief in mind).
