"Professor," Narcissa Black said, approaching the desk with her eyes open very wide indeed, "I was wondering if we might discuss my transfiguration mark."
"What about it?" Minerva asked without looking up.
"Well… it's rather low."
Minerva gave the girl a cursory glance, then looked back down at her papers and shuffled them slightly. "You have been remiss in attending classes and completing homework, and you have not demonstrated any particular competency in spell-casting. Of course your mark is low."
"But Professor…" Narcissa pouted. "I do try."
"I doubt that very much."
"Isn't there anything I could do to improve my mark?" She blinked slowly and innocently. "Anything?"
"I don't give extra-credit assignments."
"Anything?" Narcissa drew out the word, and leaned forward over the desk as she said it. Her small breasts shifted beneath her robes, and she must have caught Minerva glancing down at them, because the tiniest of smiles twitched her lips. "Anything?"
"What are you proposing, Black?" Minerva asked, as sharply as she could muster.
"What do you think I'm proposing?" Narcissa's voice had dropped to a whisper - a rather low, sensual one.
"Miss Black," Minerva said, and channelled all her years of practicing being severe into that one moment, "You can be sure that, since I don't give extra-credit assignments, I am certainly not going to accept sex as a substitute for classwork."
