After waking Ellie up, the professors spoke to the class. “As we were saying, Ellie here is going to demonstrate different ways to reach orgasm. Please form an orderly line.”

Chairs were knocked over in the rush to join the queue which quickly formed around the edge of the room. “Ellie, be a peach and stand where everybody can see you clearly,” continued the professor.

“Yes sir,” she droned, standing in front of his desk at the head of the line of students. As she did so, her hand strayed to her pussy once more, slipping the two middle fingers inside.

“Okay,” called out the professor. “Jacob, you are first in line. How would you like Ellie to make you orgasm?”

“Can I have a blow job please sir?” Jacob asked, uncertainly.

“Of course,” laughed the professor. “Take your cock out and Ellie will be happy to oblige, won’t you Ellie?

Ellie nodded, her eyes glazed, mouth open from the ripples of pleasure her fingers were sending through her.

“We have a lot of students to get through,” said the professor. “Whilst Ellie uses her mouth on Jacob, would anybody like her to use her hands?

A few students raised their hands and stepped forward. “Very good - Lisa and Martin, step up please. Now, would anybody care to fuck Ellie while she works on Jacob, Lisa and Martin?”
