Chapter Text
"Urgh Devildom history sucks ASS," Mammon grumbled loudly from the seat behind you. He slouched down in his seat enough to begin kicking your chair. You weren't exactly a fan of this class either, but Mammon made it out like learning was actually going to kill him.
"Hey," he hissed as he continued to rattle your spine with his feet. "Hey! Answer me human!" You could see the teacher at the front of the class beginning to eye you both up with disdain.
"Mammon fuck off, you're going to get us both detention," you warned, turning your head only very slightly so you could be sure he could hear you. That was enough to get him to stop kicking your chair. You went back to taking notes. And then it hit you, literally. A sizeable wad of paper batted off the back your head. You could hear Levi snickering from the seat near the window. Another ball of paper bounced off your head. You looked up to see if the teacher was still watching, but his back was turned to you as he wrote on the chalkboard. As a third paper ball skipped off your head, your blood began to boil. In a fit of rage you slammed your palms on the desk, standing and turning to Mammon.
"Oh my god Mammon I am going to floor you. Quit it." You barely had time to register the shock and awe on Mammon's face - was that a blush? - before the teacher was upon you, a sturdy, clawed hand on your shoulder.
"Student Council office. Now." You were guided by the teachers hand towards the door. As you passed his desk you could see Levi already tapping away on his DDD, live-tweeting the event. Asmodeus let out a coy "oooh!" as you took your walk of shame. As the teacher closed the door behind you, you could hear that at least Mammon wasn't going to be let off so easily.
"Don't think I won't be telling your brother about this Mammon." Well, you thought, at least you knew you were likely to get off easily with Diavolo seeing to your punishment.
After a year of studies at RAD, you knew the halls well enough that navigating them without trouble was a cinch. When you arrived, you had stuck close to the demon brothers or Solomon because there wasn't another demon in the Devildom who would approach them. You and Luke had bonded somewhat over your shared experiences, but as an angel Luke had many more ways to defend himself from hungry little demons. Now, with seven pacts under your belt, those same demons looked at you like they did Solomon, maybe even with a bit more respect than that. Solomon hadn't managed to wrangle the mighty Lucifer Morningstar under his control.
Regardless, the halls were mostly empty. One little D was stood outside of a class with folded arms, but he daren't look at you as you passed. You found your way to the Student Council room and hesitated at the door. You could hear three voices inside; Diavolo, Barbatos... You knocked as a lump formed in your throat. You hoped you were just hearing things.
"Come in," came Diavolo's always cheery voice. You opened the large, gilded door to see Diavolo sitting at his desk, Barbatos as diligent as ever at his side, and another figure you knew all too well, eyes absolutely burning into you now, perched elegantly on the edge. Lucifer. Oh crap.
"Ah good afternoon! What brings you to my office?" Diavolo smiled. Such a friendly soul for the future king of the Devildom. There were certainly cogs in that pretty head of his that whirred with schemes and plots, that much was plain. You just couldn't figure out what.
"I, uh, got kicked out of class for causing disruption," you murmured, sheepishly. You could feel Lucifer's gaze turn ice cold. He didn't move an inch, but Diavolo leaned forward, his clasped hands supporting his chin.
"I see," he muttered, tone shifting dangerously close to disappointed. "What happened?"
"Well Mammon wouldn't stop harassing me, kicking my chair and throwing things at me. When it got too much I yelled at him." Barbatos was holding back a giggle. Diavolo snorted a quick laugh before remembering who was also present.
"Perfectly capable of looking after yourself it would seem, even against some of the strongest demons in the Devildom," Diavolo nodded. "But during class is not acceptable."
"I'm sorry Lord Diavolo." The demon lord looked at you searchingly, gauging the truth of your apology.
"I can dispense punishment for this one if you wish Diavolo. No doubt I will be dealing with my impudent brother later anyway," Lucifer suddenly spoke, his voice chilling you to your very core, but also lighting a fire in your abdomen. The demon lord sat back and hummed, closing his eyes and nodding thoughtfully.
"Yes, yes I am sure you would know best what would be suitable." He opened his eyes, that deceptively sweet, honey-yellow look cutting right through you; knowing, terrifying. It made you swallow hard. "I'm sure this won't have been the first, after all." There was a slight blush on Lucifer's cheeks, you noted, as Diavolo said that. You felt the heat from your abdomen spread up your neck, your visage likely now mirroring Lucifer's. Thankfully Diavolo didn't take notice of Lucifer's somewhat pained expression. The eldest brother coughed bashfully and managed a small laugh.
"No, it certainly hasn't."
Lucifer had managed to straighten himself out and give you detention after school for your misbehaviour. Diavolo seemed to think this was somewhat of a lenient punishment, but Lucifer had promised it would not end there. He said something about extra chores and helping him with his mountains of file sorting in the office back at the House of Lamentation. That seemed to please the demon prince, so here you were, sat in the very room from which you had been ejected not a couple of hours before, watching as all the other students filed out of the building. You had even spotted Mammon racing out of the front doors like, well, a demon, but he'd stopped just long enough to turn around, spot you, and flip you the bird. You had flipped him two in return.
"That's not very ladylike of you," observed Lucifer from the classroom door. He was leaning against the wooden frame, arms crossed across his chest. You immediately straightened your stance, as if that was going to help. You heard him give a few cordial goodbyes to passing teachers, their footsteps disappearing down the hall.
"Another day on detention duty Lucifer? If I didn't know any better I might have thought you enjoyed it!" one of them joked as he left. That one had made Lucifer laugh. Looking around the room you suspected that he might just enjoy it today, because not only had he signed himself up for the task, but he had ensured you would be the only one staying behind with him. He finally stepped into the classroom, sliding the door closed behind him. There was a palpable tension in the air. You heard the ominous fluffing of feathers as a heat rose in the atmosphere around you.
"I can't believe you won't even face me," Lucifer muttered, a seriousness in his voice. You turned as quickly and boldly as you could, ensuring your eyes met his. Those blood-red irises were already boring a hole in your head. "That's better. What do you have to say about your behaviour today?"
"It was stupid, I shouldn't have let my anger get to me and cause a scene. I'm sorry," you clasped your hands in front of you somewhat defensively, struggling to maintain eye contact with Lucifer in his demon form.
"I'll say," Lucifer growled as you averted your eyes. "In fact, I'd say you've been a very naughty girl ." In that split second you realised what kind of punishment exercise this was going to be. You chanced a look back at Lucifer, who was still staring you down, every fibre of his being oozing authority. He let your realisation hang pregnant in the air, strutting towards you at the window. You swallowed hard in anticipation, but he simply brushed past, reaching for the lever that would close the blinds. One of his lower wings reached out stealthily at your hip, sneakily sweeping the back of your thigh with literally feather-light touches.
"Go and stand at that desk while I finish here," he commanded. You did as you were told, standing behind a seat in the front row. He walked up the windows to the other lever for the blinds. "Not behind it, in front." You changed position, the front lip of the desk pressing against your bare cheeks. The room was suddenly shrouded in darkness as the last lever came down. Like a predator playing with its prey, Lucifer circled the entire room before standing in front of the teacher's desk, just a couple of feet away.
"Turn around, stomach on the desk." You felt that lump in your throat again as you followed his every word. Your ass was now exposed to the world as your skirt hitched up in this new, awkward position. There was another heavy silence. You could neither see or hear what Lucifer was doing behind you. Until...
THWAK!
You let out a cry. Something wooden yet flexible had struck across your rear, stinging violently. You felt a soft breeze across the raw mark as the sound of Lucifer's wings filled your ears. He breathed in deeply.
"I've always wanted to do that," he murmured under his breath as the end of the wooden object caressed the curve of your ass. "I hope it didn't hurt too much." You could feel the slight burning sensation fading as your nerves calmed down. You shook your head. "Good." The stick-like utensil swept under your ass until it was just about making contact with your entrance. You automatically tensed, the sides of whatever Lucifer was using on you pressing against the inside of your legs.
"Relax." You took a deep breath at his command, easing your grip. The stick peeled away momentarily, before delivering another swift, lighter tap against your labia. This one didn't hurt so much; in fact, you could feel the effect it had on you dripping somewhat from below. Lucifer chuckled throatily from behind you, withdrawing his weapon from you entirely. You dared to turn around and look at him, to see what he was using. A long, thin metre stick extended his reach to you. Lucifer was once again perched on the end of a desk, with one foot raised off the ground casually. You could see the end of the stick he had used to spank you was slightly wet, and you blushed. His inky eyes met yours as he brought the stick to his lips, his long tongue seeking out your taste. Those lips curved into a sinful smile. He took a handkerchief from his breast pocket and cleaned the measuring instrument, replacing it against the wall behind the desk.
"Now," he snarled, turning back to you with a fierce glow in his eyes. "I think it's time for your real punishment."
