Sarah says, "Analyse this."

"I'm sorry?" Mr. Doe asks.

Sarah gapes in amazement. Has she spoken out loud again? When John Doe said he was head of psychology (she wouldn't mind some of that head right now), her mind had run off in a wild fantasy in which she pulled open her shirt and said 'analyse this', at that point he would take her right there and then across the classroom desks.

Only she really has said 'analyse this' and then not done anything and now she feels stupid, just as she did with the pineapple line.

As she struggles for a response, Sarah becomes aware of Mr. John Doe standing close in front of her. She looks up at him and realises that his eyes are on a point somewhere below her chin. She looks down and remembers the three open buttons on her blouse.

A mad thought takes her and Sarah thinks 'carpe diem' - seize the day.

"I said 'analyse this'," she says and pulls open her shirt with such **** that the buttons fly skittering across the room. Too late she realises that she now doesn't have a shirt to wear for the rest of the day.

It is Mr. John Doe's turn to look confused. But he is also looking at Sarah's tits as they almost tumble out of the push-up bra that she is wearing. Sarah takes this as a good sign.

Mr. Doe takes a deep breath and tries to tear his eyes away from Sarah's assets - not entirely successfully.

"Well, Miss Banks," he says at last, "I'm very flattered, but do you think that this is an entirely appropriate way of securing yourself a place at Mt. Pleasure?"

Sarah watches the suave man with his cool veneer. He is testing her, she feels sure. She is equally sure that the balance of power has begun to shift towards her. Coolly, she lets her white shirt drop. With one fluid motion she unhooks her bra and lets it fall. Her soft heavy tits jiggle pleasingly free of their constraint and John Doe's eyes are drawn back to them.

He swallows nervously. The balance of power has indeed shifted to the young woman in the pleated skirt, black high heels and little else. She stands bare chested, plucking at her nipples, waiting for him to take her.

John Doe glances down at the student list on the desk beside him, aware that his cock is creating a tent in his trousers. He quickly finds Sarah's name near the top of the list.

"You've had your 18th birthday then, Sarah?"

"Yes."

"Good," he responds. "I've got no qualms about fucking my students" [Sarah flinches at the word] "but I don't want to lose my job over an August baby."

Sarah seizes her moment again, because she too has seen the tent in John's trousers. She kneels down before him, pulls down his zip, and reaches inside. Soon her delicate fingers close around her prize and she pulls it out into the light. Then almost as soon as it is revealed, it is concealed again as Sarah's lips close over it and she takes John Doe's hard length into her mouth.

John gasps with pleasure as he feels the enthusiastic schoolgirl's mouth work its magic on him. Her head bobs up and down on his cock and her tits wobble with her motion. He strokes Sarah's hair fondly as she works away at his cock.

"You know," he muses aloud, "a young lady with your obvious talent and determination might be ideal for a particular role within our department."

With a fluid motion, and an unusual strength, John Doe lifts the schoolgirl up from her kneeling position, deposits her onto a desk and slides into her, pausing only to remove her panties first.
