Cass has an idea, but it backfires

As the score of students flooded into the room, Cass emerged from the row of shelves. She spotted Mackenzie, standing in front of the sink, wearing only a pair of socks. She had turned around at the sudden intrusion, and seemed to be frozen like a deer in headlights, covering nothing. The art professor noticed Mackenzie at the exact same moment.

"My goodness!" he shouted. This immediately got the attention of every student in the room behind him, and focused all that attention onto the nude girl standing in the corner of the room. "Young lady, what are you doing?!"

As a round of "WHOA!"s and "OH SHIT!"s echoed from the students, Mackenzie finally regained enough sense to at least cover herself with her hands. She let out an involuntary squeak of embarrassment as she did so, and her brain began racing for a helpful step 2. Luckily, Cass was still thinking clearly. An idea began to form in her mind.

"Professor Malcom!" she called, redirecting his attention over to her. Luckily for her, it was a professor she'd had a class with before. She stepped in front of Mackenzie and partially obscured her from the crowd's view. "Sorry to surprise you like that. Mackenzie here is the model for your drawing class today."

At this, Mackenzie gasped. She stepped forward a bit, pressing herself right into Cass's back, and whispered frantically to her.

"What?! Cass what are y-"

"Trust me!" Cass interrupted with a whisper back to the redhead. Mackenzie gulped nervously.

"Oh, well you should have just said so!" the professor jovially replied. Any concern he'd shown about stumbling across a naked girl almost instantly evaporated. "But we're not due for a live model today. Are you sure you have the right date, miss?"

"U-uh..." Mackenzie stammered from over Cass's shoulder.

"Ah, totally my fault!" Cass said sheepishly. "Sorry for the mix up, we'll just get out of your hair then."

Cass turned around and winked at Mackenzie. Finally she caught on to what her new friend had been trying to do. Give the professor an excuse for her nudity, while also giving her a way out of the nightmarish scenario.

"Y-yes, sorry for the, uh, surprise when you walked in," Mackenzie added, trying not to sound as nervous as she was. "We'll just be going then..."

With that, Cass began shepherding Mackenzie towards the row of shelves in the opposite corner of the room. There was likely a robe tucked away somewhere that she could put on before-

"Actually," the professor interrupted, "maybe a little practice with a live model would work fine today."

The two girls froze in place.

"Huh?" Cass asked.

"I hate to have dragged you all the way down here just for nothing. We can do today's original practice plan next class and you can still model for us today," he said.

"Uh..." Mackenzie muttered. She looked to Cass, hoping she'd know what to say to get out of it.

"That's, uh," Cass stammered for a moment. "It's really okay professor. Like I said, it was my mistake!"

"Nonsense," the professor said, already pulling a chair into the middle of the room. "Hell, you already disrobed and everything!"

"Uh, but-" Cass tried to say.

"Class, form a circle and get your sketchbooks out," the professor ordered. "Today's drawing lesson will be focused on anatomy."

"Cass," Mackenzie nervously whispered, "what do I do?"

"Give me a second," she whispered back, before stepping away from Mackenzie. Cass approached the professor and quietly addressed him. "Professor Malcom, I was wondering if maybe-"

"Say no more, I know what exactly you're asking," he interrupted. "Your friend wants you to stay for the class, right? Provide moral support and all that? Well that's fine by me."

"Oh, uh, that's not exactly-"

"I have to say, I'm impressed she was already comfortable enough to disrobe before the class even got here! Even experienced models tend to wait until the last moment for that. Though she does seem a bit nervous now that the adrenaline's worn off," he said. Then, he looked over to Mackenzie and asked, "What's your name, miss?"

"M-Mackenzie," she stuttered, still covering her chest and crotch as best she could.

"Well Mackenzie, you don't have to be nervous. Everyone here is an aspiring artist who is here to learn. Once you sit down and pose for a few minutes, I'm sure you'll find you were worried over nothing."

The professor patted the chair in the middle of the room, which was now surrounded by 23 seated students, each holding a sketchbook.

"I... uh..." Mackenzie couldn't think of what to say. She looked over to Cass, but her new friend simply shrugged back.

Mackenzie looked nervously back over to the chair. She was tempted to just sprint out of the room, to just leave the gazing eyes behind. But she knew that wouldn't be a good idea. She'd still be stuck naked on the academic side of campus. If she modeled for the class, she could at least stick with Cass and maybe even get something to wear when she was done. Not to mention, Jack was probably still skulking around somewhere nearby.

The naked beauty sighed. Was she really thinking about actually going through with this?
