You Are Mine

Summary:

A terrible title, but I'm so bad at titles I've basically given up. I just took something Lucifer says and used that pff.

It's just pure smut, I wanted to write MC having sex with Lucifer in demon form, so here it is.

Notes:

Just wanted to write some demon form smut because I'm obsessed with it. I consider this an established relationship, it's not their first time having sex, just the first time with Lucifer in demon form. I might write some for the other brothers, but I haven't decided yet. As always, you can find me on Tumbler @misc-obeyme where I take requests and other such things.

Work Text:

Lucifer's bedroom was lit by the soft orange glow of candlelight, shadows playing against the walls, the air warm. You sat on the soft silk sheets of his bed, your clothes long discarded back by the door.

Lucifer himself sat on the edge of the bed with his back to you, waiting. You ran your hands up the muscles of his back, letting one go all the way into his hair, fingertips brushing against the gray edges.

"Show me," you said, your voice hushed.

Obediently, Lucifer shifted into demon form. You watched as the horns emerged and the two sets of wings unfurled before you.

You couldn't help sucking in a breath. You had never been this close to them before.

The black glossy feathers shimmered in the light, trembling slightly. You slowly traced your fingers downward, branching them out over the tops of his wings, feeling the bone structure beneath the feathers. Tenderly, carefully, you let your fingers run along the feathered edges, overcome by just how soft they were.

You let out a little sigh. "Stunning."

Lucifer twisted around to look at you and you saw the blush that was spreading across his cheeks. He frowned at you. "Are you quite finished, MC?"

You smiled. "Absolutely not."

He looked like he was about to protest, but he stopped when you knelt over him, straddling his lap. You ran your fingers along his horns next, delicately feeling out the pattern of the ridges. He sucked in a breath beneath you.

You looked down at him for a moment. His eyes were closed, the frown still in place, the blush as bright as ever.

You leaned forward just a little more and kissed one of his horns.

His hands grabbed your waist and he pulled you into him, pressing his face against your chest. You could feel him trembling against you. You saw the way his feathers shook slightly as his wings closed in around you.

And then you felt his lips on your chest, hot and heavy. "Please," he practically moaned against you.

You had anticipated that his horns and wings would be sensitive, but you had not expected him to react quite like this. It sent a thrill through you.

You took the entire tip of one of his horns into your mouth. He squeezed you and gasped lightly against your skin. You could feel his erection pressing against your thigh.

You pulled away slightly, lips still pressed to the cool surface of his horn. "Please…?"

His hands couldn't stay still, gripping your hips one moment and running up your back the next. You could feel the tips of his feathers brushing your shoulders.

"You tease me at your peril," he said, his voice so low it was practically a growl.

You could tell he was getting impatient, that you were riling him up every time you touched his horns or brushed against his feathers. His entire body was tensed beneath you, like he was doing everything he could to keep himself restrained.

There were a lot of things you could have said then, but you decided your mouth was better used elsewhere. You pressed a line of kisses along his horn before leaning back just enough to set your lips upon the black diamond on his forehead.

It was as though you had pressed a switch by doing this. He lifted you off his lap so abruptly, you had to fling your arms around his shoulders to balance yourself.

Moments later, you found yourself sprawled back on the bed with Lucifer hovering above you, his wings still tucked around you slightly, creating a sort of canopy around you both.

Lucifer lowered himself on top of you, your bodies flush together, as he kissed down your neck. The heat flooded you, every single spot where your skin touched his felt like it was on fire. You sucked in a breath and reached up, gripping his horns in your hands because you just wanted to hold on and you couldn't resist touching them again.

Lucifer rumbled low in his throat, one of his hands running up and down your side, his mouth pausing on its way down your neck. "MC…"

You let your hands slide down his horns, to grip his face and make him look up at you. You shifted beneath him, opening your legs and wrapping them around him, locking your ankles behind his back.

You pulled his head forward just enough so you could kiss the black diamond on his forehead again. His hand squeezed your hip so hard it was almost painful and the sweet moan that fell from him made the desire already pooling in your stomach flare with heat.

"Lucifer," you whispered, your lips still pressed against him. You let go of his face, reaching up to brush your fingertips down the top set of wings, the edges of which were still tucked beneath your back.

Lucifer responded by sinking his cock into you, slowly and deliberately. Your body arched beneath him, setting free his pinned wings which fanned out in a glorious display of glossy black above you.

He was so beautiful like this, eyes half closed, cheeks covered in a blush of passion, wings spread, horns visible, the black diamond glistening slightly from the wetness of your kiss. He was already lost in your heat as he so softly moaned your name.

You both stayed that way for a brief moment, taking in the feel of each other. You, mesmerized by his demon form, him, overwhelmed by the love in your eyes.

Lucifer's first thrust was so slow it made you crazy, but you couldn't help letting out a little gasp at how good it felt. Your hands clutched at his shoulders just behind his wings, your fingers barely brushing their edges.

Your legs tightened around Lucifer as he increased his pace significantly and the way his cock felt inside you made you cry out, unable to hold your voice back. You couldn't even form words, only making incoherent noises between gasping breaths. Your heart was thudding fast, your body heating up, a layer of sweat forming at your back.

Lucifer was focused on you, his lips on the hollow of your throat, his teeth brushing lightly against your skin.

Your reactions only prompted him to go harder and faster, to bite down on your shoulder just enough to leave a mark, but not enough to draw blood. You felt the extra sharpness of his fangs. You reached up for his horns again, grasping them as he continued to thrust into you, hitting your sweetest spot every single time. You could feel the pleasure building up, so close, you were so close.

Lucifer leaned down even more, pressing himself against you and whispered in your ear, "You are mine."

Your hands slid down to hold his face again, pressing your forehead to his, holding on as your body jolted with every single thrust. You couldn't say anything back to him even if you wanted to, the sensations rolling through your body were too distracting. Even if you could, you would only agree with him.

You cried out his name as you came hard on his cock, squeezing him with every part of your body.

Lucifer growled, not at all slowing his pace, and you felt yourself careening toward over stimulation. It was so good, but you could barely think. All you managed to do was pull his head down again so you could put your mouth on his diamond one last time.

Lucifer moaned your name out low and heavy as he finally came inside you, the heat of his cum filling you up, his wings rustling around you as they shivered with the rest of him.

For a few moments, you didn't move at all, your chest heaving as you pulled in heavy breaths. You were still holding Lucifer's face and you smiled up at him before letting your hands run across his wings again.

Lucifer was flushed already, but you could still tell that he was blushing even more from the way you touched his feathers. You also knew he couldn't move away from you while your legs stayed locked around him. He was trapped there as you leaned forward again, kissing his head, kissing his horns, kissing the edge of the top set of his wings.

You soon learned that Lucifer would only put up with so much of these gentle touches before he decided to make you scream his name again.
