"I have a task for you," he said and saw her face light up.
Standing, Lucifer walked towards his trunk. "Start getting dressed."
Her smile fell. 'It's over?'
"No knickers," he added over his shoulder as he opened the lock.
Hermione didn't know what to make of that, but it sounded hopeful.
Standing up, she looked around to find her clothes and started dressing.
He came back while she was standing in her skirt and bra, two books in his hands.
He waited for her to get her shirt buttoned. "Come here," he said, sitting back down in his chair.
Eyeing the books as though they were a display of candy from Honeydukes she heard about, Hermione stood before him.
"Next Friday you are to be here at 10:30 sharp. I expect you to read both these books in their entirety by then. The first one is just a general overview of sexual practices," Lucifer said, indicating the top book. "Read it first. The other one is on sex magic."
That got her attention. Everyone knew sex magic was dark magic.
"Don't make any assumptions until you've read it," Lucifer warned. "You are allowed to suck my cock at night, but not to climax until it's Friday."
Hermione's eyes widened. "But that's a full week, the whole 7 days!"
One eyebrow rose. "I am aware, Hermione. Your education has clearly been a success." Lucifer studied her troubled face, "It's your choice. But if you wish to continue this, then you will follow my rules."
A sigh of resignation huffed out. It had all been her idea, how could she argue? "What if I come in my sleep?"
Lucifer sat back and thought about that for a few seconds. "I will punish you, which you will definitely not enjoy it. But, if that's a strong possibility, how about a Dreamless Sleep? Madam Pomfrey will give it away to girls, right?"
'Damn him. I should have kept my mouth shut....'
"Where did you get these books anyway?"
"Huh... Hermione, what else do you think I was looking for in the corner at Flourish and Blotts?"
"Oh...."
'That explained why he talked about Polyjuice.....'
"Bend over the desk."
Hermione had thought he was going to kick her out, so his order suggested a promising turn of events.
'Please make me come again....'
He flipped up her skirt, and she felt him rubbing her bum before spreading her cheeks apart.
Something cold and wet was applied to her anus, and she jumped in surprise.
"Stay still," Lucifer said. "This won't hurt."
Something pressed into her hole, and Hermione tried to relax.
"I'm inserting a small anal plug."
She tensed.
"It's nothing you can't handle," Lucifer said soothingly. "No bigger than my finger." A little half truth to ease the way.
Very lazy patience, he fucked her with the plug, waiting for her to relax.
It was slow going, but eventually the widest part slid past her anal ring and settled into place.
She was panting when he finished.
"Good girl. I want you to insert it every night and remove it in the morning. Is that clear?"
"Yes, sir."
"Do you know what Lube is?"
"I had an idea....Oh, thanks"
"Good." Lucifer smiled and patted her bottom. "Get back to your room."
'What?' She was practically dripping on the floor!
"Please, sir. I'm so close!"
"Hmm. What a pity. I distinctly remember you saying, 'no more.' I'm afraid you'll have to wait until Friday. Next time, I suggest you choose your words more carefully. As long as you're coming to me like this, I will be in control of your pleasure."
Damn him. "Yes, sir," Hermione forced through clenched teeth.
She stood haltingly, trying to get used to the feeling of moving around with something lodged in her backside.
It was weird and uncomfortable but also strangely erotic.
She walked carefully to the door.
By the time Hermione touched the handle, she knew 7 days would surely feel like an eternity.
"Hermione," he called out.
She turned.
"You've forgotten your books."
Lucifer leered at her.
Bastard.
With stuttering steps, Hermione made it back to his desk, glaring at him when she got there.
He barely contained a bark of laughter at her furious look.
Her attempted defiance was undermined by the size of her dilated pupils and the lust-fueled tinge to her cheeks.
"Sweet dreams," Lucifer said with his most wicked smile.
The bushy-haired girl huffed and turned away, learning very quickly that it was impossible to make a dramatic exit with a plug shoved up one's bum.
Sneaky bastard.

The red light of dawn warmed Hermione's window, the hazy glow of the rising sun waking her from her dream.
She turned off her alarm clock before it could ring and caused her head to throb.
Stretching on her back, Hermione suddenly remembered what day it was. Friday. She'd made it.
Curling into a ball, she reached down the back of her pajamas to feel the plug.
She'd gotten used to it during the week and grown to like it more than she originally anticipated.
The first morning she took it out (No bigger than my finger! Ha!), she spent ten minutes studying it.
Thin and pointed, it was only a little wider than her thumb and had a small indentation for her sphincter to close around.
It felt bigger than it looked.
Despite that revelation, putting it back in had been nothing short of an ordeal.
She could manage her finger just fine, but when she tried the plug, it took her fifteen minutes of wincing and panting (and a handful of lube) to get it in, and then it felt as if she had a whole wand shoved up her backside.
Hermione dreamt he was buggering her that night.
And that was just the start of the week.
It had been one long, never-ending test of her willpower.
Every day she saw him smirking at her in the morning at the Breakfast table and looking as though he knew exactly what she'd been thinking.
Each moment spent with him during the past week, could easily make her heart race.
Though Lucifer's face betrayed nothing in the class, she knew he was laughing at her.
Wednesday had been the worst.
It had begun with a vivid dream involving a shirtless Lucifer spanking her in the middle of the Great Hall.
She woke up right in the midst of a succulent slap, needing to orgasm.
Her hand slipped into her knickers before she remembered his order.
NO! She yanked her hands out with a growl.
Punching the bed in frustration, Hermione forced herself to get up and get ready for the day.
At breakfast, when Lucifer commented that she didn't look so great and kindly suggested go see Madam Pomfrey, she almost tore off his head.
Harry didn't even ask for homework that day, unsure what might set her off next.
