Something you've learned throughout your time confined to the castle was that Lucifer had eyes everywhere, just for you.
You did not regret the actions you took that ended with you here, fallen much like the king of hell. But the excessive guard he kept to you was difficult to manage, dozens of snakes, his snakes, would be spotted around, hidden from your gaze. It wasn't that he didn't trust you, no, it was that he was possessive. Lucifer had courted, coaxed and begged you to follow him to hell, sending romantic letters to tempt you to him, regardless of how dangerous it was.
It was those letters professing his intentions that were the beginning of your downfall and you broke the code of heaven, sent to hell for merely showing love for the devil. Broken and afraid is how Lucifer found you, wings tragically clipped and never to fly again and he was there, pampering you and treating you as a porcelain doll that needed care.
Despite it being hell, you never had to fight or worry about your wellbeing. And Lucifer was just as romantic as he was in the letters, the only downfall was how 'protective' he was. Or rather, how possessive. And the depths of it were only known when you finally gave into his gestures, taking that last step in your relationship. It spurred his advances, and he was far more difficult to tame, something he made you aware of frequently. He had the absolute ease of talking you into the most vulgar propositions, claiming you in every room he could find you when he was free, and it was only until later that you recall why you refused in the first place.
He wanted everyone to know that you were his, and that meant marking you in very public locations. No remorse if someone found the two of you in a compromising position, but you also don't think you ever saw those people again either.
Lucifer was insatiable and painted on a smile that always made you drop your guard. You weren't even surprised when he found you in the library due to how you heard quiet hissing earlier. "There you are my little dove. I got so worried when I couldn't locate you." He greets, invading your space to pinch your cheek. "You know how I feel about that given how special you are to me, love." An undertone of darkness saturates his words, but he merely pulls you down by the back of your neck to steal a kiss.
He wastes no time in making you gasp for breath, his tongue curling around your own. "Were you trying to upset me by leaving me all alone?" He hums between sloppy kisses, finally pulling away to lick at his lips with that forked tongue.
You lean against the nearest bookshelf to catch your breath, watching as he plants his hands on either side of you. "Lucifer..." You begin to admonish, understanding the heated glance he fixed you with perfectly. That and how you could feel reptilian skin lace over your ankles in loose threads.
"You know, I don't think we've consummated our eternal love here, my dove." Lucifer states, cutting you off with a chirp.
"Lucifer..." You try again, your tone ending in a warble when those snakes begin to slink under your clothes, confining you to the shelves behind you. You give a firm struggle, knowing that they weren't true animals, just a representation of his magic.
Lucifer chuckles, unbuttoning your blouse and kissing a path down after each bit of skin is exposed to him. Sharp teeth press into your stomach enough to make you gasp. He took time to learn every bit of your body, those little spots that made you melt in the palm of his hand. Things that made it difficult to refuse him, after all, he cared for you so deeply.
You whine loudly when those wrappings lace around the thick of your thighs, lifting them up until you're suspended. A shadow snake moves across your mouth, like a gag and Lucifer just gently hushes you. There's a perverse grin on his face as he does, fingers slipping under your clothes and sliding closer and closer to your core. "I'd be quiet if I were you my dove, we are in a library after all. You don't want others finding you like this do you?" He questions, tilting his head.
His fingers don't stop moving, pressing against your heat and rubbing along your clit. Your face feels hot and flushed, but still, you attempt to growl at the devil between your legs, kicking out in opposition and trying not to moan at his treatment.
Lucifer tuts, pulling away with an unsatisfied look, but with him comes your undergarments and he stretches them out along his fingers. "Darling, I'm only trying to show my devotion to you, must you act like an unruly mare?" He snaps his fingers, more for the theatrics than need and the shadows offer you to him. They wrap along your wrists, pinning them to your back, more of them restrain your knees and your ankles for good measure, spreading you eagle before the king.
He sends you a small wink as he tucks your panties in the pocket of his coat, letting you be lifted higher off the ground and at the height of his face. "Like I said before, you should keep those pretty lips sealed, otherwise you'll gain an audience to your unraveling, won't you?" He states with sinister undertones, forked tongue darting out to flick mischievously at you.
You feel a shiver go up your spine at the look he gives, trying in vain to shut your legs but the snakes don't give. The rosy cheeked man dives under your skirt, kissing up the insides of your thighs before getting to his intended goal with a rumbling purr.
The flat of his tongue presses against your core, slow and enjoying your taste. He makes no effort in hiding the noises he makes while planted between your legs, everything sounding sloppy and heated. In contrast, you're holding back tears as you stifle your sounds, more than thankful for the gag he gave you as he sets to bringing you to the end of your pleasure. Your throaty shriek isn't as muffled as you'd like when that tongue of his burrows into your channel, far longer than it usually is just to satisfy you in every way he wanted. You can't help but buck your hips whenever the forked tips brush inside you, feathery light and enough to tickle in just the way to send tremors up your spine.
As was his nature, Lucifer doesn't allow you to enjoy the indulgences of his tongue for very long, letting it slip out slowly, dragging the muscle along every wall inside you as he did so.
He kisses your flesh apologetically when he hears the pathetic wail that comes out of your mouth, letting you struggle as you come off the high you almost had. You knew he didn't mean it as the man was a sadist and always wanted to break you in these moments, have you solely dependent on what he could give you. His fingers grip the ends of your skirt and finally push it off his face and letting you glare daggers at the devil while he pushes it the fabric up.
He was satisfied with slitted eyes as he breaks to play with your clit, mouthing the small nub with sharp teeth. You could feel his grin as you attempt to stay quiet, knees feeling weak and trembling against the restraints. "I know, you must be so frustrated with me, my dove," He murmurs, making sure to exaggerate the way he messily slurped against you, "But I can't just simply finish you off until I get to see those darling little wings of yours. You know they're my favorite."
You feel heat break out across your face at his request, flushed more than his current habitation between your thighs. "Pervert!" You call out loudly, muffled but your point gets across as he chuckles, languidly flicking his tongue at you.
You shift unsteadily when you feel those snakes dive into the back of your shirt, the tips rubbing at the wing mark on your back. You resist the wriggling feeling that was coursing down your spine with each touch but it’s useless when your fight was against Lucifer. Small ivory wings pop and tear at your shirt to make room, they flutter with each touch.
Lucifer's grin widens at their reveal, panting like a freak before quickly returning to your pussy, fingers diving inside with nary a resistance and curling along your walls.
Like a starved dog, Lucifer sucks and curls his tongue around your clit, leaving no place untouched on you. And with his new fervent need, you are quickly racing to the edge of your orgasm once again. You feel drool puff out the edges of your lips as you mewl and moan against your gag, head leaning back like it would help you breathe easily.
It doesn't and you feel lightheaded anyways.
Your wings seize, flaring out wide with the snakes beginning to caress and wrap around them gently, never impeding their movements but being absolute with their possession. You arch your back and try and shut your legs again as your pleasure hits, climax making you wail. Lucifer doesn't stop, letting you ride it out as he savors every bit of your orgasm, tongue pressing flatly against your pussy in the effort to wipe every bit up.
He had a lovestruck expression stuck on his face, purring all the while. "Don't you look positively darling like that." He cooes, resting his head on your inner thigh. The devil grunts, and you knew exactly what he was doing when his teeth bite at the fat of your leg. "Sweetheart, would you spare some attention to me? Seeing you like the finest work of art has me all hot and bothered for more." He pleads, licking his tongue across his lips.
Those snakes tighten along your limbs before sinking you lower; your gag being pulled away to let you breathe. You merely sigh, giving in to his needy kiss when he's close enough.
You'd be in this library a while longer it would seem.
