Anatomy class

...a classroom door labelled Anatomy.

Inside the classroom, the heirarchy was obvious. There was no furniture; students on their hands and knees formed chairs, footrests, and other students laying across their backs to form desks. This furniture was in service of a select few who were actually sitting or stacking books on them, and the obvious ruler of the roost was Valerie, who lounged back on two students and rested her feet on two more while a fifth gave her a foot massage and a sixth knelt between her legs to eat her out. Despite her predicament, Jessica marveled at the uniform posture of the furniture students, but it didn't take long to see why -- tiny clamps on their nipples, genitals, earlobes, and other sensitive areas were strung together with thin chains, so that too much movement would yank painfully. As she watched, a footrest's arm weakened and she slumped; with a gasp of pain, she corrected herself.

"Mistress," the football player dragging her announced, "we found this in the halls."

"Hmm? Oh, right; I'd forgotten about that. Thank you."

The footballer dropped Jessica's foot, kissed each of Valerie's hands, and left.

"If I may continue, Mistress?" the teacher asked timidly.

Valerie nodded.

"Right. Well, today you will be learning how to orally please a mistress. That is, those of you who need to know such things will." She snapped her fingers. "Bring in the class pets!"

A door in the back of the room opened, and several chairs were carried in. In each chair, a girl was tied; hands behind her back, legs spread wide. They were sobbing and trembling, but it was impossible to see their facial expressions, because their heads were entirely hooded. Still, Jessica recognised them.

They were still wearing their cheerleading uniforms.

Or sluttier versions, anyway. Their t-shirts were tube tops that left nothing to the imagination, too flimsy to stay on if they hadn't been held up by very vicious-looking nipple clamps; their skirts were now miniskirts that covered absolutely nothing with their legs tied painfully wide. They wore no panties, of course. The entire squad was present, except of course Jessica herself.

"Today, we will have some practice," the teacher announced. "Select slaves will each bring a class pet to orgasm using only their mouth. You may undress them and touch them wherever you wish, so long as it is done entirely with your mouth. The pets have been informed that if they come today, they will be very severely punished. As incentive, a **** who fails to get their assigned pet off within ten minutes will be punished in their place. Now, which slaves shall participate today?"

Valerie spoke up. "I want my ****," she said, nudging Jessica with her foot, "to get that pet off." She nodded at Tiffany, Jessica's best friend.
