Vial of Black Ink - "Wicked Witch"
"Trick or treat?" she called through the door upon hearing a knock on the wood.
"How about you just unlock the door. I've been giving candy to those children all night with their similarily scripted speech. I just want to go to sleep, Hermione."
"There's a couch in the living room if you refuse to answer the question."
At his groan from beyond the door she giggled; the accompanying growl that had to be filling the hallway told her that he had heard her. "I will alhohomora the door if you don't open it."
"But I placed the counter-spell on it," she informed him of what he aleady knew. Which made it even more worthwhile when she heard his forehead connect with the door a moment later.
"For the love of- Oh, for heaven's sake. Treat. As in I get to sleep in my own warm comfy bed and not that blasted thing you call a couch."
"You got a problem with my couch?" she asked, fingers hovering over the door knob.
"It's leather. You can't sleep on leather."
"Yes, you can."
"Not comfortably."
Figuring she had tortured him enough she unlocked the door before grabbing the door knob, turning it to swing the door inward. She watched with delight as Barty just stood in the doorway, staring at her.
Specifically at the green lingerie she currently had on.
"You... Wicked witch."
She laughed as he grabbed her around the waist, picking her up to deposit her on the bed shortly after. "I thought you wanted to sleep," she teased as she watched him practically tear his own clothes from his body.
"I thought you were giving me a treat," he countered and Hermione spread her legs further so he could see the lingerie more clearly, the bottom of which was nearly soaked through with her arousal.
