“Let's try something else tonight,” Lucifer purred against Alastor's mouth as they kissed. The angel's thumb stroked the demon's cheek before sliding his hand into his hair, threading his fingers through the red locks to cradle his head. Softly, so softly , he pressed his lips to the sinner's cheek, then to one of his eyelids, and lastly to his forehead. 

Chaste, sweet. And yet, burning with deep, hungry desire. 

“Something new.”

The Radio Demon's ears perked up in curiosity, and he lifted his head to brush his nose against the King's cheek. 

“If you're…” Lucifer grinned, brushing his mouth against Alastor’s again, enough to make his skin tingle, but not quite making the contact he craved. “Amenable?”

The demon hummed, his hands slowly gliding down the angel's neck, across his shoulders and over his back, feeling every inch of warm, perfect skin, every inch of firm, corded muscle before pulling the King flush against him. 

A quiet groan escaped Lucifer's throat and the sinner's eyes fluttered shut as he pulled his bottom lip between his teeth, reveling in the feel of his partner's lithe body against his. 

Oh, how he loved to see his angel like this, aching with want, and all for him .

“What did you have in mind?” He asked smoothly, teasing his claws along the skin of his partner’s back, savoring in the shudder that coursed through him. 

The King buried his face into the sinner’s neck, trailing his lips down his throat as one of his hands slid down Alastor’s stomach and over the waistband of his pants to slowly, gently rub him through the fabric. A soft moan slipped from between the demon’s lips, the muted warmth and steady strokes filling him with need . 

“I want to watch you,” Lucifer breathed wistfully, the words hot against his skin. 

The sinner felt his face flush, the beat of his heart picking up and his partner chuckled softly at the sudden wave of heat caught between them. 

“ Watch me?” The Radio Demon teased softly. “Why would you ever want a thing like that ?”

Lucifer chuckled low, the sound vibrating out of his chest as he pressed his own growing hardness to his partner’s leg. 

“Must I explain again what you do to me?” He asked with faux exasperation, his hand loosely closing around Alastor’s cock, languidly pumping it up and down, the soft cloth between them forbidding real contact, but the friction encouraging him to harden nonetheless. 

The demon sighed a shaky breath, his fingers pausing on the King’s back, his claws instead gripping him tightly, digging into his skin. 

“It would drive me insane ,” his partner continued. “Watching you…touching yourself to the thought of me…”

Against his thigh, Alastor could feel Lucifer’s own length throb at the mere thought , an unsteady groan rising out of him. The sinner swallowed hard, thrill trilling in his veins, and despite his initial embarrassment, he felt himself twitch with excitement. 

To that, the angel hummed delightedly as he ran his thumb over the newly-formed dark spot on his pants.

“And it seems…,” he teased with a devilish grin. “You might like it, too...hm?” 

The Radio Demon tilted his head into his partner’s, lightly bucking his hips into his partner’s hand and smiling mutely when he heard the soft curse.

“I suppose it couldn’t hurt to try,” he conceded, and, though his insides twisted with trepidation, he had to admit…the prospect was tempting. Exhilarating, even.

Especially if it brought his angel pleasure . 

His King exhaled slowly as he tried to contain his excitement, dragging his lips across the demon’s cheek before murmuring, “ Good boy .”

At the words, the sinner’s cock twitched in his partner’s hand.

Oh, fuck .

With another sly, understanding grin, Lucifer began laying a line of kisses down Alastor’s neck and over his chest, taking his time to wrap his lips around each of his nipples, swirling his tongue around the buds, winding the demon up so tightly until his back was almost painfully arched off the bed and he thought he would simply burst. 

The angel continued preparing him, working to ease his nervousness as he worshiped every inch of his body above the waist with that sinful mouth. He scraped his teeth across the sinner’s skin, making it tingle and burn with every new press of his lips, leaving behind searing, claiming marks and the Radio Demon could do nothing but watch, enraptured. 

And when his King finally reached the waistband of his pants, he slid them down with an agonizing slowness, reveling in the sight as the sinner burst free of the straining fabric before tossing the garment off the side of the bed, then crawled back up, pressing a new trail of kisses up the line of the his partner’s jaw.

“Don’t be scared, dearest,” the angel urged, his voice soft and calm and assuring, cooling the worry in his gut. “If you don’t like it, you can stop at any time.”

The demon swallowed again, breathing slowly and steadily as he nodded his head. With that, his partner pulled away completely to make himself comfortable on the other side of the bed, leaving the sinner hot and cold at the same time. 

Alastor shifted to his knees as the King lounged back against the headboard, gaze heavy and hooded with lust as he watched the demon palm his cock. Slowly, awkwardly, he began to stroke himself, the skin at the back of his neck prickling under the weight of his partner’s gaze. 

“That’s right,” Lucifer’s voice whispered encouragingly, and out of the corner of his eye, the sinner saw that the angel had unfastened the buttons of his own lounge pants, freeing himself enough to take his own member in hand, matching his partner’s leisurely pace, his gaze glued to the movement of Alastor’s hand. “Just like that, darling. See? This is what you do to me.”

The words helped to embolden the Radio Demon, the breathy quality, the desire he heard in the words filling him with courage that began to overcome the self-consciousness. 

The muscles in his back eased, and he spread his legs a little wider, so he could sit back, lean back on his free hand to give his angel a better, uninterrupted view. 

“Oh, fuck ,” the King breathed, and Alastor let his head fall back, closing his eyes as he focused on the feel of his fingers wrapped around him, pumping idly for several minutes, letting his precome overflow and drip from the head of his cock and onto the sheets, taking his sweet time as he basked in the soft gasps and praises he could hear coming from where Lucifer was situated on the bed. “ Jesus , look at you. You’re gorgeous. ”

The words caused him to throb and a moan spilled from his lips, the arm he was using for support wobbling behind him. 

Fuck , he thought. If the King kept that up, he was sure the show would be cut short. 

But the demon continued on, slow and steady, building himself up, losing himself to the feel of each pump. 

“You’re doing so good, Alastor,” his angel commended. “Keep— ah, shit —Keep going .”

Gradually, the demon picked his pace up, fueled by his partner's pretty words and breathy groans, falling forward on the same arm as the tension in his body pulled his muscles taut, forcing him to nearly fold himself in half, aching for release, reveling in Lucifer’s pleasure.

But after several minutes, his brow furrowed. His arm moved at a furious pace, fingers wrapped tightly around his length but…it wasn’t enough. 

He could feel it there, his end. It was close, but still so far away. And his hand…wasn’t cutting it.

He needed—

“More,” Lucifer demanded tightly as if reading his mind, and Alastor’s face burned again, his eyes sliding back open, lifting his head to look back at the King. 

His partner’s face was just as flushed as his, his gaze clouded with lust , his own hand still mirroring the sinner’s speed as best as he could.

But the look in his eyes…he knew .  

He knew, the bastard. He—

He needed it too .

“Why don’t you come over here and help me, then?” The demon asked between huffs of breath, leaning heavily on his arm as it shook, his whole body wound so painfully tight with the need to let go . 

“Ohhhh, fuck ” the wavering groan spilled from the angel’s lips at the prospect, a sheen of sweat shining across his forehead. “I would, darling…but— shit —where’s the fun in that…,” A wicked smile spread his lips wide. “When you are perfectly capable…of doing it yourself?”

It took a moment for the sinner to understand his meaning, but when the realization took hold, his face flushed further, hotter . 

This was unlike anything the sinner had experienced before, something that no one had ever asked of him before. It was embarrassing— degrading , even—and he should hate it, putting himself on stage like this, letting Lucifer see this vulnerability.

But…he didn’t.

In fact, he seemed to… like it. 

And the King’s praising words stirred something in him, spurred him on. 

The angel wanted this, had asked for it specifically . And not because he wanted to humiliate Alastor, but because the mere sight of it would bring him just as much enjoyment as performing the action would bring to the sinner himself. 

So, the Radio Demon allowed multiple tentacles to form at his back, conjuring them in thinner, shorter lengths than what he would normally use in battle. They slid out of his skin and he guided them to run along the lengths of his body as he glanced over at Lucifer.

“Like this?” He asked coyly, feeling a dark sense of delight as he watched his partner stare, wide-eyed and unblinking, as his extra appendages gently glided across his nipples and over the swell of his ass. His angel swallowed audibly, a trickle of drool escaping the corner of his mouth.

“Perfect,” the man breathed, so low and reverent Alastor almost didn’t hear him.

A tremor ran through the sinner and he shivered, taking slow, even breaths as he allowed one limb to wrap around his length, warm and soft and wet .

“Oh, fuck ,” he gasped quietly, letting his head drop forward, his hair falling in his face. He leaned forward, on both hands now, as the tentacle began moving up and down, up and down, stroking his cock slowly but steadily, squeezing him so tight that if he closed his eyes, he could almost mistake it for being inside of Lucifer himself. 

Slowly, he eased another limb down the length of his back, sliding it in between his cheeks, gingerly circling it around his entrance before pressing it in, just barely . His elbows trembled, threatening to give out. 

He heard the angel hiss, and the Radio Demon took that as positive reinforcement, slowly pushing the tentacle in further and further, until it just barely brushed that spot deep inside him. 

And at that first, single touch, his arms did give out for a moment, a whimper slipping out of him as he caught himself before face-planting completely. 

“Does that feel good?” The King rasped and Alastor nodded eagerly as he lifted himself back up on unsteady arms, saliva beginning to pool in his own mouth. His chest heaved as he opened his eyes again, staring down at his hands, curled tightly in the blanket.

God. Oh god , that was so —

“Good. Keep going,” his partner said tightly, the words desperate, ground out through clenched teeth, followed by a wavering curse. “ Please .”

The demon dared another peek at his angel. The other man was sitting forward now, his eyes hooded— lust-drunk —as he tracked the movement of the appendages, his cheeks blazing gold, his hair completely mussed as if he had been rubbing his head against the headboard in his ecstacy. His pants were a mess of precome, a near-constant drizzle dripping out of the head of his cock, and he simply looked…

Undone . 

All because of this, because of him . 

A shiver coursed through Alastor at the sight and, at the King’s request, he began guiding the limb back out, and in again, and—

Oh fuck, oh fuck, oh fuck .

It took everything in him not to hit the ground running. He wanted—no, needed —to draw this out, for the both of them. His angel looked so beautiful like this, right on the edge of breaking, and he never wanted it to end.

So, he forced himself to take his time, his eyes fluttering shut. His panting and whimpering grew quick and loud and desperate as he kept his pace steady, his trembling arms lowering him closer and closer to the bed with each new pass, unable to hold his weight much longer, ready to snap under the pressure of both of their pleasures.

As he felt the tentacle inside of him wriggle and writhe, accurately hitting his spot each time, the saliva that had gathered in his mouth began to dribble out, dripping down his chin and seeping into the blanket.

And he didn’t care. He didn’t care that he must have looked like some half-feral animal in the middle of his damn heat.

It simply felt so good, and especially with his angel’s eyes affixed to him, greedily drinking him in, in that lust-filled haze, his gaze filled with a deep, ravenous hunger like Alastor was a juicy cut of meat ready to be tasted, devoured.

The thought made him throb, almost painfully. 

He didn’t have words for how much he liked it, how much he craved this attention. Even if he hadn’t realized it before.

“Fuck, Al,” Lucifer’s words came out as an uneven whisper and the demon peered up amidst his own bliss, locking eyes with his partner. The King’s pupils were blown wide as he kept his gaze glued on the sinner, the movement of his hand on his cock quick and jerky. “ Fuck , you’re so pretty like this, I— Ah —”

A low moan interrupted him as he came, hard and fast, spilling himself all over his hand. 

“ Shit …” 

The sight itself had Alastor’s cheeks burning anew, the knowledge that he had caused the angel such pleasure had him nearly gasping for air. 

And as the appendage continued to work him from both ends, the demon buried his face into the blanket, his claws tearing the fabric as his fingers curled into it. His breath was hot and wet against his face as he moaned into the cloth, picturing the King coming for him so quickly and suddenly over and over in his head. 

It was such a beautiful picture.

His entire body shook as he rutted his hips into the tentacle like the wild animal he had let himself become, desperately seeking its release. 

So close, so — close —

“Not yet,” Lucifer’s voice said, soft but insistent and, at the sound of his voice, the sinner’s extra limbs came to a painful, grinding stop.  “Don’t come yet, dearest.”

Alastor nearly collapsed into the bed with a frustrated groan, but gentle hands wrapped around him, turning him over onto his back. He glanced up at the angel as he rested the demon’s head in his lap.

“I want to watch you,” his partner reiterated with a soft smile, brushing the sweat-dampened fringe out of his eyes. “I want you…to come for me .”

A strangled whine rose out of Alastor’s throat and, with a light chuckle, the King slid his hands down the demon’s arms, gathering his own hands up before raising them and pinning them on the bed at either side of his head.

“Go on,” he encouraged. “I want to see you .”

With a tired nod, the sinner commanded the tentacles’ assault on his body to begin again; the one that had gone loose around his cock tightened, the one that had gone lax inside of him hardened. 

Immediately, his body tensed again, heat pooling in his core as the appendages worked him, harder than before. Faster. His brow furrowed as he tried to focus on the movement, tried to work himself all the way back up to the edge, looking back up at his angel for approval.

But, that wasn’t what he found.

And what he did find made him burn with an intensity far greater than the sun.

A sly, playful smile had spread Lucifer's lips wide and a positively wicked gleam sparkled in his eyes.

“Come on, dearest,” the other man teased, tilting his head to the side as he leaned over his partner. “You know you can do better than that.”

A whimper escaped the demon, his ears flattening back against his head. 

“Don’t you want to feel good , darling?” the King cooed to him, and Alastor nodded once more, now a shy, mousy thing far different than the feral animal he had been mere minutes ago, the embarrassment flooding him again under the heavy weight of his partner’s gaze. “Of course you do. Go on.”

The demon swallowed hard, averting his eyes away from the angel’s, forming another tentacle on his back, allowing it to slide into view.

“There you go,” Lucifer praised him. “Just like that.”

Squeezing his eyes shut, the sinner guided the tendril towards the other already inside of him, and began pressing it in, stretching himself wide, wider than he’d ever felt before.

A shock of pain jolted through him and, with a cry, his back arched high off of the bed, his arms tensing and struggling to break free of the King’s hold, his hands grabbing hold of his partner’s wrists for support. 

“Slowly, my love,” his partner murmured, loosening his grip just a bit, giving the demon more room, his thumbs gently stroking the skin of his arms where he held them down. “Go slow. Relax .”

Alastor exhaled a long breath, forcing his muscles to ease, commanding the tentacles for work in tandem with each other—and oh, fuck did that feel amazing . 

“There you go, darling. Now, angle your hips up a bit,” Lucifer instructed softly and the Radio Demon complied, more limbs growing out from his back. He slid them in under his backside, letting them raise him up and off of the mattress. Opening his eyes, he glanced back up at his partner, watching as his gaze honed in on the motion before he looked back down at the sinner. “Doesn’t that feel better?”

He couldn’t bring himself to nod again, his eyes nearly rolling back in his head as he let the tentacles steadily bob him up and down in the angel’s lap, climbing him closer and closer to his climax, but never quite enough to throw him fully over. 

The King watched him closely as minutes dragged on, those eyes raking over his face, scouring his expression before shaking his head, a lazy, knowing smile curling his lips up. 

“It isn’t enough, dearest,” he tried to reason with the demon. “You need more .”

“How?” The word came out as a whine, desperate and needy. 

“You know how.”

Another whimper clawed itself out of him, a pathetic and…almost fearful bleat of a sound as his insides coiled nervously.

“Let go, Alastor,” Lucifer encouraged softly, his hands strengthening their hold around the demon’s arms once more, reminding him of their weight, providing that much needed assurance. “I’m right here, darling, I’ve got you. Just— let go .”

The sinner’s grasp on the angel’s wrist tightened, his claws sinking into the delicate skin. 

“Let go,” the King whispered once more, and the Radio Demon simply couldn’t take it anymore. 

He surrendered himself over to the tendrils, letting them do as they pleased. More burst out of his back, wrapping around his thighs and forcing them wider, winding around his arms to hold him more firmly to the bed, pushing their way past his lips and into his mouth, curling itself around his tongue, reminding him of the way Lucifer had kissed him so, so many times before.

“ God ,” the angel breathed as he watched, his voice full of adoration and wonder and love as the tentacles fucked him now with reckless abandon. “Just look at how gorgeous you are, Alastor. I wish you could see… fuck. ”

The sinner moaned and cried, his chest heaving with quick breaths as he was wound up tight, so tight. So close —

“Please,” the Radio Demon begged, words muffled by the limb, tears springing to his eyes. The heat between his legs grew and grew until it was almost too hot to bear as Lucifer continued to eagerly egg him on.

“There you go, darling. You’re doing so good; you’re glowing .” 

“ Please ,” he sobbed again, saliva starting to trickle out of his open mouth. He writhed on the bed, desperately seeking his end, lurching his hips up into the tentacle wrapped around his cock in an unmeasured, jerky rhythm. 

“You’re almost there, sweetheart,” his partner said, his voice hoarse and breathless as he stared down into the demon’s eyes. Alastor’s face flushed impossibly further, and he whimpered, forcing one of his many tentacles to come up, hiding his face from the sheer weight of the King’s watchful eye. “No, no —” And at his insistent command, the limb paused, lowered. “Look at me when you come.”

And though he wanted nothing more than to shy away, he didn’t. He kept his eyes locked with Lucifer’s, the dark intensity of his gaze spurring him on further, and he could feel his release rush through him, pulling his muscles so taut that it hurt . 

“That’s it,” the King almost growled , his voice tight and gravelly as it rumbled out of his chest. “That’s it, Alastor, right here. Look right here .” 

His hand tightened around his angel’s in a death grip, claws digging into his wrist harder until he could feel warm blood spilling over his clenched fingers.

“ Come for me .”

The words undid him. Broke him. 

He felt the tentacles squeeze him tightly in preparation, and with a strained, choked cry, the Radio Demon was thrown over the edge, spilling himself all over the bed, himself, and the limb that was wrapped around him, milking him as he rode out the waves of pleasure, until he was left completely and utterly empty .

Alastor’s whole body shook with exhaustion as he collapsed down onto the bed, his chest heaving as he attempted to catch his breath, forcing the tendrils to release him and recede into his body once more. 

“Good,” the King whispered as he loosened his grip on the demon’s arms, running his hands up and down them, working to comfort him as he came down from his high. “ Good boy .”

Water still streamed from his eyes as he lifted his gaze to his angel. 

His face was impossibly kind as he focused on the sinner’s body, checking him over for any injuries or too-deep imprints from where the limbs had clutched him too tight. 

“Lucifer—,” he started, his voice almost wobbly and his partner quickly paused his ministrations so he could meet the demon’s eyes, examining his face for a moment before taking his head between his hands, gently wiping his tears away with his thumbs.

“Are you alright?” Lucifer asked carefully as he leaned over him and Alastor turned his head into one of the angel’s hands, offering a slow, tired nod. But as more tears escaped the corner of his eyes, the angel’s brows dipped in concern. “Are you sure?”

“I’m okay,” he assured his partner, though his chin trembled, and his voice started to break. “Just…”

Mortified, he laughed weakly, trying to pass it off as he raised one arm to wipe the water from his cheeks with the heel of his hand. 

Why was he crying? He had enjoyed it immensely , and yet—

“Sorry, I—I’m not upset, I—”  

“Hush,” Lucifer cooed, his voice barely above a whisper as realization crossed his face, his expression softening. He took the demon’s hand, removing it from his face before leaning down to him and pressing his forehead to Alastor’s. “I know, it’s okay.”

“Then, why—?” 

The demon was shaking with sobs now, his breath catching in his chest with each inhale as he squeezed his eyes shut, his quivering hands desperately moving to grab hold of Lucifer’s head, fingers curling in his soft, blonde hair, feeling the need to hold him there, to make sure he wouldn’t move away. 

He felt raw, so bare. So… exposed , in a way he’d never felt before. 

“Lucifer—,” he tried once more, but the word came out more as a whine than anything.

“Shh, it’s okay,” his angel said again, his breath a warm, comforting puff against the sinner’s face as he hooked his hands on his partner’s arms, running his palms up and down them, trying to soothe him. “This is normal. Just breathe , okay? Breathe with me. I’m right here.”

They sat there for what felt like minutes, Lucifer guiding each of Alastor’s inhales, then his exhales, until the tears had dried, and the cries had faded. Until the trembling had calmed, and the beat of the demon’s heart had slowed and returned to normal.  

And when the angel had dubbed him ready, he pulled back a bit, gathering the Radio Demon up into his arms, holding him firm and close as he sat back against the headboard one more, dragging the sinner along with him. The King draped his partner across his lap as he reclined, and Alastor finally let himself relax, curling into Lucifer’s embrace, resting his head against his chest. 

“It’s okay,” his angel reassured once more, pressing a soft kiss to the Radio’s Demons forehead, then to the top of his head. “It was intense, I know. But you did so good, darling. So good.” 

Alastor sighed in relief, a small smile creeping back onto his lips as the King buried his nose into his hair and inhaled deeply.

The sinner lounged against his angel’s body, loosely wrapping his arms around him as they sat quietly for another long while, the demon falling into a sleepy haze as the King’s slender fingers brushed through his hair, his other and resting on his hip, his thumb idly rubbing gentle circles into his skin. His lips pressed tender kisses to his head as he whispered soothing praises into his ear.

“Are you ready for a bath?” Lucifer asked eventually, and half-asleep, Alastor whined, tightening his hold on his partner. His angel breathed a laugh, and snapped his fingers. 

The faucet in their ensuite roared to life, and the demon’s ears twitched at the sound of water splashing as it filled the enormous claw-footed bathtub. 

With a dramatic, heaving sigh, the King pressed one last kiss to the sinner’s forehead, then pulled himself out from under the Radio Demon and climbed out of bed. He surveyed Alastor for a moment before reaching towards him, sliding his arms underneath him.

“Come on, you,” he teased, a light chuckle in his voice as he lifted the sinner off the bed and, once more, into his arms, bouncing him up for a more secure grasp. “I know how much you hate feeling sticky .”

Alastor laid his head on Lucifer’s chest, letting the man bridal-carry him into the bathroom. And when they reached their destination, the angel set him down on the edge of the tub before going about the room, grabbing towels and various bottles, happily humming a bright, sweet tune.

He set the towels on the lid of the toilet before easing himself onto the lip of the other end of the tub, looking between two bottles of what the sinner could only assume was bubble bath.

“Apples or…lavender?”

The sinner gave him a look. 

“Lavender it is,” he laughed, then dumped a healthy amount into the water.

Finally, when the tub was mostly filled, Lucifer waved his hand, the water coming to a quick, complete stop. He stood from his spot and pushed his pants down, letting them fall to the floor before he stepped out of them, kicking them towards the hamper in the corner. 

He stepped into the bathtub then, and reached for Alastor once more. He sat himself down into the soapy water, then set the demon in front of him, between his legs. 

And immediately , the heat of the water had the sinner groaning in ecstasy. 

“Oh fuck ,” he breathed, sliding himself further down into the water, letting it flow over his aching muscles. “That feels good .”

“I bet it does,” the King chuckled, gently gripping his partner’s head, guiding it back until his hair was submerged, wetting it down. Alastor raised his eyes to Lucifer’s, who grinned down at him as he ran his fingers through the strands, making sure that it was completely soaked before leaning down and kissing the tip of his nose. “You’re beautiful, you know?”

A slow blush crept into the Radio Demon’s cheeks, and he offered his angel a soft, lazy smile. He sat up a bit, slicking his hair back and out of his face before sitting back against the King’s chest, laying his head back on his shoulder. 

“You’re one to talk,” Alastor replied haughtily, tilting his head so he could see his partner’s face. “You’re the most beautiful being in all of creation, so the stories say.”

“Oh?” The angel asked casually, raising one brow as he peered down at the sinner. “But what do you say, darling?”

He shrugged.

“I would agree with them.”

The other man laughed again, beaming with pride as he looped his arms around the sinner’s chest and arms, holding him close. 

“Then I suppose I would know beauty when I see it, don’t you think?”

The demon hummed with amusement, then sighed out slowly through his nose, relaxing himself against the King’s body, letting his eyes fall closed. Lucifer’s arms around him tightened in response, his cheek resting against his temple.

“Was it bad?” The angel asked after a few moments, the lilt of his voice down, suddenly. Worried. “We don’t—we don’t have to do it again if you didn’t like it.”

“No,” Alastor admitted quietly. “No, it…was different but—”

“Is that code for too much ?” 

“Lucifer,” he breathed in faux exasperation despite the renewed smile that appeared on his face, opening his eyes again.

“I’m— ugh .” The angel raised his head then, reaching for the washcloth and the bottle of body wash he’d laid out on the lip of the tub, then squeezed a little out and began lathering it up. “I just want to make sure , Alastor. I know sometimes it's hard for you to…to open up like that.”

The sinner was quiet for a moment, his gaze lowering to the bubbles that had overtaken the surface of the water.

He hated making his partner worry. But he couldn’t deny how it made his heart swell that he did , that he cared so much for the demon, that his top priority was making sure all was well.

“I know,” the sinner assured him. “I know. But…it was good. I’d even go as far to say that I… may have liked it.”

He felt the King perk up at that.

“Really?”

Again, Alastor hummed.

“I wouldn’t mind doing it again sometime,” he continued. Behind him, Lucifer snickered a bit, and began gently running the soapy rag over his chest. “Though a little preparation beforehand would be appreciated.”

The angel’s hand paused for a moment. 

“Right…of course.” His voice was quiet, the realization hitting him. “Of course. Sorry.”

“Don’t be, dearest,” the demon replied, sitting up a smidge to press his lip to his partner’s cheek before contentedly nestling himself back against his chest, letting the other man resume gliding the washcloth across his body. “I enjoyed myself just fine.”

“Okay,” the King replied. “Okay, good.” He breathed out a sigh of relief that was half a chuckle. “I’m glad. It was…amazing. For me.”

“Yes,” the demon teased, raising his hands to slide up Lucifer’s arms, his claws teasing his angel’s skin, forcing a shiver to tear through him. “I could tell.”

Against his temple, he felt the King’s lips spread wide in a grin. 

“Stop that,” he warned with another little laugh. “You’re too tired for a second round.”

“Mmm,” Alastor agreed, heaving a dramatic sigh, waving one hand dismissively as he grinned up at his partner. “I do suppose you’re right. I guess I’ll let you off…for tonight, anyway.”

“Is that a threat?” Lucifer asked, his eyes sparkling with delight, his own smile happy. Satisfied. Fulfilled , even. 

The demon breathed in deeply, and exhaled slowly, raising his hand out of the water, placing it on his angel’s cheek. 

“I love you,” he sighed. The King’s face faltered for a moment, his eyes widening as his gaze scoured the sinner’s expression. 

And when he overcame his shock, the grin that overcame his face was simply breathtaking—brighter, even, than the sun.

The most beautiful being in creation, indeed.

“I love you too, Alastor,” he breathed, his voice shaky, as if he would burst into tears. With a pleased hum, the Radio Demon pressed a soft kiss to the side of his partner’s neck before nuzzling his nose into the skin there, breathing in his familiar, addicting scent.

They fell into a comfortable silence as Lucifer carefully washed Alastor down and after several minutes, a sense of calm washed over the demon. He sighed, suddenly feeling tired , so tired that his eyes refused to stay open any longer.  

“That’s right, darling,” his angel whispered knowingly, his voice paired with the steady, even movements of his hand and the gentle wave of the warm water soothed him, lulling the Radio Demon to sleep. “Get some rest, I’ll handle everything here.”

He smiled softly and, with a quiet hum, sighed slowly through his nose, allowing himself to fall into the angel’s absolute, loving care.

And a moment later, everything went dark.
