She'll hide her body inside the nearest body of water, the jacuzzi

Kirumi didn't have the biggest breasts at the academy- that was actually a pretty stacked contest, pardon the pun- but they were still a very good size, far too much to hide while she slipped past the two gentlemen entering. She needed a way to conceal as much as she could. Quickly, she slapped down the feminine bun of her hair, until it looked more like a disheveled boy's might, and she made the perilous descent into the nearest body of water available to her: the jacuzzi. She hadn't bothered to take off her towels before entering in...

"That's a mistake!" she suddenly realized, clenching her teeth. If anyone got close enough, they'd definitely wonder why she was wearing an upper-body towel in the bath. She'd be seen for a girl almost instantly! In desperation, she flung the towel out of the tub and onto the floor, then vowed silently to clean it up before she left. It hurt her, on a professional level, to ruin the floor she'd just mopped, but **** times called for **** means. Now, her sizable breasts could be seen in a wavy shape beneath the water's bubbles... at a glance, one might mistake them for a man's chest, but any prolonged stare would reveal the truth. Really, even her slender shoulders could speak to that truth. She bit her lip, red-faced, pleading silently for the boys to avoid the jacuzzi as she sunk deeper into it, submerging herself to her chin.

Just then, she noticed the stack of maid's clothing she'd left near her bag. There was nothing to do about it now... she'd just have to hope that the two ignored it. Why wouldn't they? Would it be normal to inspect someone's belongings before entering the spa?

"This is a trial... a trial I must overcome," she spoke quietly to herself. Her duty to her people had been tested so many times before. This was just another test... It wasn't impossible... She could escape without disrupting the two boys' spa trip and she definitely wasn't going to be seen naked in the boy's side of the spa... To do any less would be to fail not just herself, but every person in Japan! She needed to be someone that could be relied upon... and how could anyone rely on her, if they thought she was a pervert who went naked in the men's room?!
