Chapter Text
Lucifer didn’t often traverse through the halls this late at night, however a particularly difficult stack of paperwork demanded a class of Demonus as compensation. Walking down the staircase he basked in the rare silence that befell the house. Passing by the common room, he was about to turn right into the kitchen when he noticed a strange noise filling the otherwise silent hall. Standing completely still, trying to determine the source of this noise, Lucifer heard a small whine on top of the strange buzzing sound. Was it coming from your room? Stepping closer to your door, he held his ear less than an inch away from the closed entrance. Lucifer isn’t one to snoop, especially not in your business. He often fears he may find things he doesn’t want to see if he gets too close to you.
With his brows knit together in confusion, he’s about to turn away to brush it off when he hears breathy “Fuck…” followed by a drawn out whine come from your room. His blood ran cold and his feet rooted into the floorboards of the hallway at the realization of just exactly what he’s listening to. You, behind this flimsy wooden door, are using a toy on yourself. Panting, moaning, trying to be quiet. His cock twitches at the thought of you sprawled out on your bed, naked and sweating. He’s stuck in a never ending cycle of imagining you and being blessed with hearing your whimpers of pleasure. Part of him felt guilty; he shouldn’t be here. You didn’t know he was here and for all he knows you don’t want him here. He’s intentionally kept you distant because he knows he’s falling for you and he can’t bear the thought of you thinking about someone else during intimate moments like these. Despite everything in his body telling him he needs to leave before he discovers something he doesn’t want to find out, Lucifer remains stationary just feet away from you. You, unknowing; him, getting harder with each passing muffled cry as you try to keep quiet.
“Fuck, Lucifer…”
Time stopped for Lucifer as his heart dropped. Fuck. You discovered him. He doesn’t know how, but you managed to figure out he was just outside your door; listening to you touch yourself like a creep. His throat runs dry as he tries to think of a response before you let out another moan, getting higher pitched. If you knew he was here why would you continue? Lucifer let out a sigh he didn’t know he was holding when your whines grew louder and more frequent - as well as continuing to drop his name from your glorious lips. You didn’t know he was there. You were imagining him to get off. The realization flipped a switch in Lucifer and his already stiff cock sprung to life, forming a massive tent in his pants. Lucifer looked back and forth in the hallway to make sure no one had snuck up on him while he was so transfixed by your sounds before palming himself through his pants.
The sounds of you coming undone were like music to his ears. Begging for him, despite knowing he wasn’t there - or at least thinking he wasn’t. Still rubbing himself, the sound of the buzzing coming to a stop struck him with the realization that he needed to leave before you somehow found out he had heard the entire thing. As quickly and quietly as he could, Lucifer booked it straight for his room - Demonus be damned. Lucifer barged through the door to his bedroom, shutting and locking it quickly so as to not be disturbed. The sounds of your moans haven’t left his head and he prays they never do.
Lucifer was not a demon that regularly indulged in the sins of the flesh. Rarely did he ever see the need for sexual gratification as he didn’t often become aroused. That was until you showed up. Lucifer was not an idiot, he knew what arousal was - but for the longest time he couldn’t figure out why you , a human , drove him to do things he’s done only a handful of times. Every time Lucifer had touched himself to the thought of you he had been plagued with guilt from the uncertainty of if you even thought of him the same way. He thought for sure you pined after one of his brothers, for they all treated you better than he did. They spent more time with you than he did. Most of all, they expressed their interest in you.
But there you laid, in your room, crying out his name. Lucifer shuddered as he ripped his gloves off and threw them to the floor, untying his tie with his free hands. Unbuttoning his pants and pulling his underwear just low enough to free his aching cock, Lucifer hissed in pleasure as he grabbed the base of his dick, not bothering to undress any further. Sitting in the chair he was just diligently doing work for Diavolo in, he leaned back and pushed his hips forward, using his other hand to rub the stream of precum leaking from his tip up and down his thick shaft as lubricant. For once, Lucifer could touch himself to the thought of you without being plagued by guilt. Instead pride swelled in his chest as he knew you wanted him. You desired him. You could have anyone you wanted, be it angel, human, or demon. You could have Prince Diavolo himself, but you think of him as you squirm in bed at night. The swell of pride increased his lust tenfold as he choked back a whimper at the thought of you underneath him, sweaty and panting. Looking up at him with your beautiful eyes, lips puffy from his hungry kisses. Face flushed as you let out moans you can’t contain because he would learn your body like the back of his hand.
Lucifer could feel his cock throb in his hands as he got closer to his climax. He imagined marking you up and down your body; places you’d never be able to hide. He wanted everyone to know you’re his . His breath became unstable as his fist pumped his cock, losing his rhythm in the throes of pleasure. He could practically see you there, sitting between his legs, his cock stiff in front of your face. Looking up at him through your lashes as you wait patiently for your reward with your mouth hanging open. It’s his cum you crave, his cock you ache for, and most importantly, him you’ve chosen.
Lucifer let out a choked moan of your name as he threw himself over the edge, tossing his head back with ropes of cum shooting all over his desk. Waves of pleasure racked his body and he heaved his chest as if he’d just run three marathons. Lucifer basked in his satisfaction as his cock softened and he mentally prepared to clean up after his mess. He wasn’t sure how to take your relationship to the next level yet, but he was more than happy to know that his feelings are not unrequited. A wave of tiredness washed over his body and he decided he can think about it more tomorrow - for tonight, he gets to sleep with the thought of you.
