Mr. Stirnweiss

Mr. Stirnweiss paces in front of the blackboard, nervously as always, his fingers dusty with chalk. Except for the whirring noise near the door the room is quiet. “Well then, we have a second-order derivative. What is the power rule for that? Mr. Stimson?”

The shortish white boy in front with the plaid shirt and black pants says, “You just use the power rule for the first order, and do it twice.”

“Correct. . . and why is it not a good idea to use the Leibniz notation? Miss Fairweather?”

“Kch - kch -” Her breasts quake as she struggles to get out a word. She is in her special chair. Another orgasm overtakes her and with each jolt her tough soles slap loudly in unison against the floor. She beats the top of her desk with her fists. The unseen vaginal and rectal dildos are doing their job, pistoning into her one then the other for the entire class period. The vaginal dildo has ridges on top to massage her G-spot. Struts rising from her desk press vibrating cups against the huge nipples.

“Kch -- kch -- s-sorrrry -- kchh -- OHH!” The special bristly pad over her clit just moved again.

Sighing, Mr. Stirnweiss calls on Miss Sung who knows the right answer.
