Lilith's art class

"You absolutely sure I can't convince you to model again? You're already undre-"

"NO!!!!" Joanne snapped at Lilith before she could finish, not being pleased about the professor's clothes disintegrating fluid. Joanne stormed out of the building in a robe Lilith gave her.

"Ah dang. I genuinely do need a model for today's session, and nobody's available..." she thought to herself.

She walked into her classroom full of students taking her class. 

"Well, we don't have anyone to model for us..."

She removed her baggy sweater and revealed her bare chest. Some of the students nearly had their eyeballs jump out their sockets, completely taken aback at the normally conservatively dressed Lilith stripping right in front of them. While they have drawn human models before, they were usually dressed.

"I'll model for this class just this time..." She winked as she dropped her trousers around her ankles, revealing everything to the now mesmerized class. She was unexpectedly in shape as her clothes hid her figure.

"Are you people gonna pick up your jaws and draw or what?" 

The students obliged and got to work. She began to do some poses in front of the class as the students started sketching her. She enjoyed making some of the visibly aroused students embarrassed by looking at their crotches and then smirking. 

"I see some of you are enjoying this session. Hope my poses isn't making it too HARD to draw!" Most of the class turned redder than they already were. 

Finally, the class ended, and she put her clothes on and bid the class farewell. She chuckled a little as some of the students were either hunched over or holding an object to cover their crotches as they left the class.

"That was a lot of fun," she thought to herself. "I should do this more often..."
