Black buxom Mistress

Lady Sheela, the buxom woman on page 54."

There is a slight pause.
"Ah yes, her. Do you want her dressed in any particular outfit?"

You flip over to the outfit part of the catalogue.
"Yes, I would like her to wear the strict principal uniform but with some kinky underwear underneath."

"Good choice."

You pause and hold the phone away from your face as you get a small giggle fit. Then you hear the woman voice again and put it back to your ear.
"scenario."

"I´m sorry, could you say that again?

"Do you want any special scenario?"

"Nah, nothing too specific as long as she´s on top."

"Very well then, she will be with you in just ten minutes."

The woman hangs up and you immedately start laughing. You keep doing this for a while until you hear a knock on the door.

You fly up and trip on a note being slipped under the door. You pick it up and read it:
"You´re the innatentive student and I´m the strict Headmistress."

What the fuck?
You open the door and there Shela is. She´s wearing a tight black business suit over a simple white shirt. Her thick black hair reaches her shoulder and is slightly curly. She has a large briefcase with her and is pouting down disaprovingly at you.
