Bellatrix/Narcissa
Happy Birthday

"Cissy…wake up! I've got a surprise for you…" She leans over her sister's bed, her long glossy hair hanging down and skimming teasingly over Narcissa's face.
Narcissa shivers, but doesn't open her eyes. No, she screws them up tightly, like a child trying desperately to go to sleep.
"This is a dream. It must be a dream. I can wake up whenever I want."
Bellatrix lets out a soft laugh; Narcissa really is adorable.
"I wouldn't count on it, darling. If you died now, well, you'd never wake up again."
"You're not saying you're going to kill me?" Narcissa doesn't know what to think. With her sister, anything is possible.
"Don't be silly, Cissy, that was just an example. It would be useless if I killed you before I had the chance to wish you happy birthday." Bellatrix puts her hand up to her sister's frightened face and starts to trace her pale cheekbones with a thin finger.
"What?"
"I've got a lot to teach you. I've been hearing all sorts of things back home. Almost sixteen, and still a virgin? That will not do…"
Narcissa can no longer lie there, stiff as a board an utterly vulnerable to Bellatrix's advances. She draws the covers up to her chin and sits up, gazing at her in disbelief.
"You're not saying…you can't be suggesting that…"
"Hush now, Cissy; stop being such a prude. Look, I brought some cake to celebrate. I think you'll enjoy it." She takes out a small pastry, simply dripping with icing.
Bellatrix forces it into Narcissa's mouth before she can make another move, then puts a hand over her lips and pinches her nose shut so that Narcissa has no choice but to swallow it.
"That was…good." She says, gasping for breath. Maybe this won't be so bad. Maybe Bellatrix only came here to chat about getting a boyfriend.
"Of course it was." The woman springs on the bed with a sudden agility. She straddles Narcissa's hips, pinning them down so she can't move.
"Bella! What…no!" Narcissa almost screams before remembering she's still in the dormitory, surrounded by other young witches. She'd hate to get in trouble. But Bellatrix is smirking at her now and has ripped the covers away, revealing that warm nights make Narcissa less inclined to sleep with something on…
Bellatrix puts her hands on Narcissa's shoulders and leans over to whisper in her ear.
"That wasn't icing."
