After the class...

Of all of the humiliating experiences Katie had been subjected to that day, life modelling was the worst so far.

She was instructed to contort her body into a variety of different poses, exposing her most private areas in all sorts of embarrassing ways. The regular shifting of her core resulted in her stomach rumbling; noises that Katie thought sounded deafening in the quiet room.

The AC had been cranked up for everyone's comfort...apart from the model, who shivered violently as the cold tendrils of air passed over her bare skin.

With no watch or phone, Katie didn't know how long she had been on display for when the teacher finally brought the lesson to an end.

As the students began to pack away her art supplies, Katie slammed her thighs together and folded her arms across her chest. She hurried towards the annex, but had barely covered two paces before the teacher called her back.

"Katie? Where are you going?"

"Do you have any clothes-?"

"Don't worry about that now," the teacher waved away the question, dismissively. "It's always polite to speak to the artists after a session; good manners will get you more jobs in the future!"

Katie didn't WANT any more modelling jobs, but had **** but to do as requested.

"Thank you for letting me paint you."

One by one, the artists filed past her, shaking Katie's hand. The teenager was just glad that none of them were staring lustfully at her; although she supposed you become immune to that sort of thing after painting so many nude bodies.

When the final student had left, Katie slumped onto the nearest desk. She was SO hungry! Her eyes lit up when the teacher approached with a freshly-laundered robe in her arms.

"Thank you, thank you, thank you!" Katie gushed as she pulled the garment around her shoulders. She let out a gentle moan as she enjoyed the feeling of cotton on her skin; after spending so long nude, it felt good to finally be able to wear something again!

The brunette was quickly brought back down to Earth when the teacher helped her back to her bare feet and walked her out of the classroom.

"Wait, where are we going?!" Katie asked, trying not to freak out. She couldn't walk around her school in just a robe! Sure, it was a lot better than being dressed in her birthday suit...but she didn't even have any shoes on!

"I've spoken to your step-mom, she'll pick you up outside," the art teacher explained. Katie stumbled out into the cool night to see a car with its engine running.

Padding over as fast as she could on bare feet, Katie pulled on the rear door; but it was locked.

As if on cue, the driver's window descended, to reveal Bev grinning at her.

"Can you unlock the door, please?" Katie asked, with a sense of foreboding.

"Hand me that robe, and I'll think about it," Bev winked.

"B-but I'll be naked!" Katie gasped, clutching the garment tightly.

"Katie, I'm your sister. Don't you trust me?"

Katie didn't trust Bev as far as she could throw her, but with no alternatives presenting themselves to her, she reluctantly untied her robe, and tossed it through the open window.

"NOW will you let me in?" Katie demanded, hugging herself and bouncing from foot to foot. "Come on, you promised!"

"I said I'd think about it," Bev smirked, enjoying the control she had over her step-sister.

Katie looked pleadingly at her; surely not everyone in her family was evil?!
