Here it is: my first attempt at Harry Potter fanfiction. Basically, it's a twist on those ever so slightly squicky stories where Snape tries to rape Hermione and she's either this helpless maiden or a sexy student temptress. This drabble version examines what might have happened if the situation had arisen with an in-character Hermione…
Snape advanced, his throbbing manhood in his hand. Hermione cowered against the desk.
"No, Professor," she whimpered, "don't do this, please, I'm scared…"
Snape smiled coldly. "Oh, don't worry, Miss Granger," he sneered. "This won't hurt a bit. Well, actually…it could…" Snape gave a nasty laugh and reached out for the young virgin.
She suddenly stood up straight. "All right, then," said Hermione coolly. Reaching inside her robes, she drew out her wand and raised it over her shoulder. She pointed it straight at Snape and cried:
"Expelliarmus!"
Severus Snape was never quite the same, either physically or mentally, again.
