Practice makes perfect

Summary:

When Lucifer had switched to being a half woman, specifically having different sex than Alastor, he doesn’t know what he can do intimacy wise. Waking himself up to watch Lucifer’s he slept, and when his love finally shows concerns, Lucifer finally realizes he just needs to be taught, and he’s willing to do that.

Work Text:

Lucifer stirs slightly as Alastor shifts position, his bleary golden eyes cracking open just enough to see the radio demon's silhouette in the dim lamplight. "Mmmph... Al... why're you movin'? S'too early..." He murmurs sleepily, pressing his face deeper into the pillow even as his fingers curl tighter into the other demon's nightshirt. "Not lettin' you go..."

 

Alastor chuckles softly, the sound rich and warm like melted caramel, his clawed fingers carding through Lucifer's sleep-mussed hair with practiced ease. "Now why would I leave when you make such an adorable sight all tangled in the sheets, mon cher? I was merely observing how peacefully you sleep when you're not busy overthrowing heavens or tempting mortals." His grin widens as Lucifer grumbles incoherently, pulling him closer until their foreheads touch. "Besides, someone has to ensure you don't sleep through another millennium."

 

Lucifer huffs dramatically but doesn't pull away, his tail curling possessively around Alastor's thigh as golden eyes blink up at him with rare vulnerability. "Don't need to be..." His protest is cut short when Alastor leans down to capture his lips in a slow kiss. When they part, Lucifer chases the contact for half a second before composing himself. "...what's the real reason you're up so early, hm? You're never awake before noon unless there's trouble."

 

Alastor stills for just a moment too long—Lucifer catches the minute hitch in his breathing, the way his claws flex against his thigh—before he laughs with practiced ease, turning his face away to hide the faint blush creeping up his neck. "Oh, you know me too well! But don't trouble your pretty little head about it—you should be worrying about catching up on seven centuries of beauty sleep, mon roi." His grin sharpens as he presses a claw to Lucifer's lips. 

Lucifer snickers, but his eyes search at Alastor's own, looking for the answer within them—those crimson depths usually so full of mischief now flicker with something darker, something that makes the hairs on the back of Lucifer's neck stand up even as he leans into the touch. "Flattery won't work this time, darling," He purrs, catching Alastor's wrist and pressing a kiss to his palm. "You forget I invented deflection—now tell me what's got you tense as a hellhound on a leash before I—" He yelped when Alastor suddenly rolls them over, pinning him to the mattress.

 

Alastor looks down at Lucifer, hating the fact that he’s persistent, but he finally relents with a sharp exhale through his nose. "Fine, fine—you always were annoyingly perceptive." His voice drops lower, uncharacteristically hesitant as his claws trace idle patterns along Lucifer's collarbone. "It's just... ever since you switched over to having…..y’know, I haven't been able to—" A frustrated growl rumbles in his chest. "I don't know how to please you properly anymore. And it's maddening."

 

Lucifer stares at him for a beat—then bursts into laughter, rich and unguarded, his whole body shaking beneath Alastor's grip. "Oh, you idiot," He gasps between giggles, wiping at his eyes. "All this brooding because you didn't ask? Darling, I'd let you take me apart with a spoon if you wanted—gender's never stopped us before." His laughter softens into something tender as he cups Alastor's face. "But this is what's got you wound up? Really?"

 

Alastor blushed harder, “Shut it” He said lowly, his ears flattening against his head as he avoided eye contact, claws digging ever so slightly into the mattress. "It's not funny—you know I don't like not knowing things, especially when it comes to you." His voice drops to a whisper, rough with frustration. "I can't stand the thought of disappointing you. Not when you... when you look at me like that."

 

Lucifer's laughter fades into something softer, his fingers tracing the tension in Alastor's jawline before pulling him down into another kiss—this one slower, deeper, tasting of forgiveness and promise. "You could never disappoint me," He murmurs against his lips, breath warm. "But if you're that worried... why don't I show you? You do know how to ask nicely, don't you?"

 

Alastor is silent for a long moment, his ears twitching—then he exhales sharply and nods, his grip loosening just enough for Lucifer to shift beneath him. The king of Hell doesn't waste time, sitting up smoothly to straddle Alastor's lap, his tail flicking lazily as he leans in close enough for their breaths to mingle. "There. Better vantage point, don't you think?" 

Alastor kisses Lucifer, mumbling a soft 'mhm' against his lips as his hands slide down to the small of Lucifer's back—barely grazing the waistband of his underwear where it peeks out beneath the rumpled white shirt. His claws catch on the fabric, tugging it slightly askew as he deepens the kiss with a low hum.

Lucifer lets the kiss linger longer before pulling away with a wet smack, his lips swollen and pupils blown wide—he smiles teasingly before booping Alastor's nose with a fingertip, chuckling at the way his ears twitch in response. Shifting fluidly in Alastor's lap, Lucifer turns until his back presses flush against the radio demon's chest, his tail curling possessively around Alastor's thigh as he arches just enough to expose the soft curve of his stomach. His voice drops to a whisper—hot breath ghosting over Alastor's collarbone—"Ready to start baby?"

 

A shudder runs through Alastor's frame—his breath hitches before he exhales sharply through his nose, nodding as his claws flex against Lucifer's hips. "Yes," He murmurs, voice rougher than intended, fingers sliding slowly up the inside of Lucifer's thighs with deliberate pressure, tracing the sensitive skin there. His thumb brushes teasingly against the crease where thigh meets groin, testing boundaries—but stops short of crossing them, his breath warm against Lucifer's ear.

 

Lucifer hums before stilling Alastor's hand with one tap of his own. He then gets himself to lift his lower body a little while his hand pushes his underwear down enough to show his own parts to view—his smirk turns wicked as he hears Alastor's breath catch, feeling the sudden tension in the demon's fingers around his waist. "See? Nothing to be nervous about. Same me, just... rearranged." His tail flicks playfully against Alastor's thigh.

 

Alastor swallows thickly, his ears twitching as he stares—then exhales sharply through his nose, his grip tightening slightly on Lucifer's hips. "I know that," He mutters, voice rough. "I just want to know how to—how to please you now. Properly." His claws dig in just enough to leave faint indents, his breath hot against Lucifer's neck. "Tell me what you like. Show me."

 

Lucifer chuckles softly—"Yes, sir"—before one of his hands guides Alastor's own, his grip firm yet gentle as he presses the demon's fingers against his slick folds. "Soft when you approach," He murmurs, arching into the touch with a shiver. "Gentle pressure here—yes, just like that—" His breath hitches as Alastor's fingers finally slip inside, his tail twitching against Alastor's thigh. "Mmmph—good boy."

 

Lucifer looks at Alastor's hand placement before moving his own hand out of the way—Alastor's fingers don't move, hovering with unnatural stillness as if afraid to misstep. Turning slightly, Lucifer catches the rare uncertainty in his lover's gaze, the way his ears flatten slightly against his head. Without a word, Lucifer shuffles closer, his right hand cupping Alastor's cheek as he leans in for a slow, reassuring kiss. "Relax," He murmurs against his lips. "You're thinking too much."

 

Alastor then loosely tenses himself out of it—his breath stutters before he exhales sharply through his nose, his eyes half-lidded and soft as he finally gets himself together. His claws retract slightly from where they'd been digging into Lucifer's thighs, his shoulders relaxing as he focuses on the warmth of Lucifer's body pressed against him. "Better?" Lucifer asks with a smirk, rolling his hips experimentally against Alastor's still fingers—earning a choked noise as Alastor's grip tightens reflexively before forcing himself to loosen again.

 

Alastor hummed, his fingers twitched a little before he stilled again and thought about what the next move was—Lucifer's quiet encouragement finally loosens the tension in his shoulders. He tentatively curls his fingers deeper, rewarded by Lucifer's sharp inhale and the way his thighs tremble. "There you go," Lucifer purrs, arching into the touch, his tail flicking against Alastor's wrist teasingly. "Just like that, darling—no need to be so careful."

 

Lucifer then guides Alastor's fingers upward with deliberate slowness, his breath hitching when Alastor's fingertips brush against the swollen nub hidden beneath slick folds. "Shift up—yes, right there," He murmurs, voice thick with want. "Now press—ah—just like that, circles, small ones—" His words dissolve into a moan as Alastor obeys, his claws retracting completely in concentration, leaving only the pads of his fingers to work magic.

 

Alastor watched Lucifer’s reactions, finally deciding to do something of his own—he kept drawing those teasing circles before putting his mouth to Lucifer's neck, kissing softly at the sensitive skin there. His other hand drifted lower, slipping past his previous position to push two fingers deep into Lucifer’s heat while his thumb continued rubbing slow, maddening circles against his clit. The dual stimulation drew a shuddering gasp from the king, his thighs tensing around Alastor’s wrist.

 

Lucifer moans—soft, breathless—before murmuring. "Good job," His voice already wrecked, neck bending further to give Alastor better access to nip and kiss at the delicate skin there. His golden eyes stay locked on Alastor's hands working between his thighs, watching those slender fingers slide in and out of his slick cunt with practiced precision. His hips roll in tiny, desperate circles against Alastor's palm, chasing the building pressure as his claws dig into the sheets.

 

Alastor hums against Lucifer's neck, his breath hot and ticklish—his lips barely brush the shell of Lucifer's ear as he murmurs low and rough. "Mmm, such pretty noises you make for me, darling, such a cutie when you're all desperate like this." His words are punctuated by a slow, curling thrust of his fingers, pressing deep enough to make Lucifer gasp, his thighs trembling around Alastor's wrist. "Tell me—do I finally know how to please you properly now, mon roi?"

 

Lucifer arches sharply, his breath hitching—his hips jerk against Alastor's hand as those fingers press deeper, hitting just the right spot. "Fuck yes—right there—don't stop—" His voice cracks halfway through, his tail wrapping tight around Alastor's wrist like a leash, pulling him closer as his thighs tighten around the demon's fingers.

 

As Alastor worked, he felt himself grow hard in his own briefs, the blood rushing to his crotch with every moan Lucifer let out—he grit his teeth, trying to keep his composure as Lucifer melted in his arms, his own arousal pressing insistently against the king's lower back. His breath came ragged against Lucifer's neck, torn between focusing on his ministrations and the way his hips ached to grind against Lucifer's warmth.

 

Lucifer arched back instinctively, pressing flush against Alastor's hardness with a low, approving hum—his breath hitched mid-moan as he rolled his hips backward just enough to tease, feeling Alastor twitch against him. "Look at you—such a quick learner," He purred, his voice wrecked but smug, fingers tightening in the sheets. "A few more lessons like this and you won't need me guiding those pretty fingers—ah!—fuck, right there—" His words dissolved into a gasp as Alastor crooked his fingers just right.

 

Lucifer barely had time to process the shift before Alastor snapped—one moment he was grinding back against the demon's arousal, the next he was pinned flat beneath him with a muffled yelp. His breath caught as Alastor hooked his hands under his thighs, lifting him effortlessly until Lucifer could feel the heat of his breath against his soaked cunt—the scent of apples and cinnamon thick in the air between them. "Al—oh—" His protest died in his throat when Alastor's tongue swiped up his slit in one slow, filthy stroke.

 

Alastor tasted Lucifer again before plunging his tongue inside, hoping this would feel good—as certainly the taste was so much better. The flavor of him flooded Alastor's senses as he laved deeper, his claws digging possessively into Lucifer's thighs. Lucifer's answering moan was music, his hips jerking weakly against Alastor's mouth as his tail lashed wildly against the sheets. "Fuck—yes—just like—ah—" His voice broke on a sob as Alastor's tongue curled inside him.

 

Alastor then abandoned one of Lucifer’s legs to then place his fingers on the nub Lucifer showed him and as he used his tongue inside, he rubbed at the same time—the dual stimulation tore a ragged cry from Lucifer's throat, his back arching off the mattress as his thighs trembled violently around Alastor's shoulders. The radio demon growled low in his chest, the vibrations sending shocks of pleasure through Lucifer's core as his fingers worked mercilessly, circling that swollen bud with just the right pressure. "Al—Al—I can't—oh God—" Lucifer babbled, his claws tearing through silk sheets.

 

Alastor kept going until he could feel how much Lucifer's moans and breathing came together—his pulse fluttered wildly beneath his tongue, his thighs shaking like a leaf in a storm—before pulling back with a wet sound, his fingers slowing to gentle strokes against Lucifer's overheated skin. He kissed Lucifer's pelvis tenderly, his breath hot against flushed flesh as he murmured. "Are you alright, mon cher? Did I... overdo it?" His voice was uncharacteristically soft, his ears twitching with concern even as his own arousal pressed insistently against the mattress.

 

Lucifer breathed heavily, one hand going to his forehead, fingers laced on his face as he looked down at Alastor with blown pupils—his voice came out wrecked and incredulous. "How the hell did you learn all of what I didn’t even explain?" His thighs twitched around Alastor's shoulders, still trembling from the aftershocks, his skin glistening with sweat.

 

Alastor smiled a bit before lowering Lucifer's lower half down and shifting himself to be face-to-face with Lucifer, his claws tracing idle patterns along Lucifer's flushed chest. "The way you sounded was instruction enough, mon cher," He murmured, voice thick with smug satisfaction, "I didn't need visual cues when your moans told me exactly what you liked." His grin widened as he pressed a kiss to Lucifer's racing pulse.

 

Lucifer sighed, allowing that to go as he then felt a brush against his leg—he looked down to see Alastor's hard-on straining against his own underwear. A wicked smirk curled his lips as he repeated the phrase teasingly, "Speaking of things we like..." His fingers trailed down Alastor's stomach, pausing just above the waistband. "Seems you've been very attentive to my needs—shouldn't I return the favor?"

 

Alastor blushed deeper as he felt Lucifer's fingers ghost over the waistband of his underwear, his ears flattening against his head—he caught Lucifer's wrist with surprising gentleness, shaking his head slightly. "Sorry darling," He murmured, voice rough with restraint, "But what I want... is to feel you properly this time." His claws traced Lucifer's hipbone. "Let me take care of you—all of you."

 

Lucifer's smirk softened into something tender at the unexpected restraint—his fingers stilled, curling around Alastor's wrist instead as he arched an eyebrow. "Always so patient when it's about me," He mused, his thumb brushing over Alastor's pulse point. "Tell me, darling—are you sure you don't want me to—" His teasing was cut short when Alastor went to kiss against his neck, sucking on different areas downwards.

 

A shiver ran down Lucifer's spine as Alastor's lips trailed lower, his breath hitching when sharp teeth grazed his collarbone. The king's golden eyes widened as Alastor hooked his thumbs under the waistband of his underwear, tugging them down in one smooth motion. "Someone's eager," He breathed, his smirk returning as his legs fell open invitingly.

 

Alastor huffed, his ears twitching as he avoided Lucifer's gaze—his fingers trembled slightly against Lucifer's thighs, claws retracted completely for once. "It's not—ugh—it's different when you had your usual... equipment," He muttered, voice uncharacteristically vulnerable. "I know how to handle that—knew exactly how much pressure to use, where to touch—but this?" His claws flexed helplessly. "What if I hurt you? Or—or don't satisfy you properly?" The admission came out in a rush, his blush deepening.

 

Lucifer smiled softly at the admission, catching Alastor's restless hands between his own—his thumbs traced the knuckles where claws usually protruded. "Even if you did disappoint me—which you won't—there wouldn't be a single negative thought toward you, darling," He murmured, pulling Alastor's palm to his lips for a kiss. “I love you, not just what you can do for me. That doesn't change based on things like this." His grin turned wicked as he nipped at Alastor's fingertips. "Now stop overthinking and let me show you how much I adore your ridiculous brain."

 

Alastor exhaled sharply—then kissed Lucifer fiercely, pouring all his pent-up frustration and adoration into it, his claws finally sliding down to grip Lucifer's hips with renewed confidence. "Fine," He growled against his lips, voice rough with want. "But you'll tell me if I—ah—if I do something wrong." His fingers slid lower, tracing slick folds with deliberate slowness this time, no longer hesitant—just savoring. "And you'll scream when I do something right."

 

Lucifer arched into the touch with a breathy moan, his golden eyes darkening as Alastor's fingers pressed deeper—his tail curled possessively around the radio demon's wrist. "Mmmph—promise," He purred, lips brushing Alastor's ear. "But darling, you really think I'd be quiet even if I tried?" His laughter dissolved into a gasp as Alastor's thumb found his clit, circling just shy of too rough—the perfect edge of pleasure-pain that had Lucifer's thighs trembling.

 

Alastor growled low in his chest—the sound vibrating against Lucifer's neck as he nipped at the sensitive skin there—his fingers curling just right inside Lucifer's heat. "Not in the slightest," He admitted, voice thick with satisfaction. "You never could keep that pretty mouth shut." His free hand slid up Lucifer's stomach, tracing the dip of his ribs before pinching a nipple sharply—drawing a startled cry that melted into a wanton moan.

 

Lucifer arched into the dual stimulation with a choked gasp, his thighs clamping around Alastor's wrist—his golden eyes fluttered shut as pleasure coiled tight in his gut. "Oh—fuck—don't stop—" His fingers tangled in Alastor's hair, tugging sharply. "Just like that—yes—Al—" His voice cracked as Alastor added a third finger, the stretch burning deliciously—his tail thrashed wildly against the sheets, knocking a pillow to the floor with a soft thump.

 

Alastor's breath hitched at the desperate tug of Lucifer's fingers—his own arousal throbbed painfully against the mattress as he watched the king unravel beneath him. "So responsive," He murmured against Lucifer's sweat-slicked collarbone, his tongue darting out to taste the salt there. "Tell me—does this feel better than before?" His fingers twisted cruelly inside Lucifer's cunt, drawing a sob—his thumb never let up its relentless circles, pressing harder just to hear that breathy whine.

 

Lucifer arched violently, his claws raked down Alastor's shoulders as he gasped. "Yes, Al—please—I need—fuck—need you inside," His voice cracked on the plea, thighs trembling. "Use that pretty cock—ah—push every inch into me until I forget this ache—" His golden eyes were glazed, pupils blown wide as he rutted shamelessly against Alastor's wrist.

 

Alastor froze mid-thrust, his fingers stilling inside Lucifer—his ears pinned back as he stared at the king's flushed face, realization dawning. The request—the implication—sent a jolt of panic through him. He'd never... not like this. His claws retracted completely as he swallowed hard, voice uncharacteristically small. "Lucifer... I-I don't know if I can—" His breath hitched. "What if I—hurt you?" 

 

Lucifer breathed heavily, finally looking deeply at Alastor as he found the other hand that wasn’t in him to tangle their fingers together—his grip tightened painfully, golden eyes burning with desperate affection. "I love you with every piece of my heart," He growled, voice raw. "But if you don't fuck me silly in the next ten seconds, I swear to me I'll leave this bed and find something else to ride until I forget your name." His threat dissolved into a gasp as Alastor's fingers twitched inside him.

 

Alastor stared at him before finally taking the answer, pulling his fingers out of Lucifer with a wet sound that made them both shiver—his claws retracted completely as he shifted back just enough to push his underwear down, his cock springing free against Lucifer's slick folds. His thick length sliding through Lucifer's wetness as he rubbed up and down slowly, letting the king feel every inch that would soon be inside him. His ears flattened against his head, breath ragged. "Still certain, mon cher?" He managed, as he felt how good the wetness was.

 

Lucifer's answering laugh was breathless—his golden eyes locked onto Alastor's cock as he arched up, deliberately dragging his slick cunt along the length of it with a shuddering gasp. "Don't make me repeat myself," He purred, wrapping his legs around Alastor's waist to pull him closer—his tail flicked impatiently against Alastor's thigh. "Unless you want me to go find someone else who—ah—who'll fuck me properly—" His taunt turned into a moan as Alastor finally lined himself up, the blunt head pressing against his entrance.

 

Alastor snarled—the mere thought of someone else touching Lucifer like this sending white-hot fury through his veins—and before Lucifer could finish that sentence, he grabbed both of Lucifer's legs and threw them over his shoulders, pinning him in place as he slammed their mouths together in a searing kiss. At the same moment, he thrust hard—burying himself to the hilt in one brutal stroke, tearing a ragged scream from Lucifer's throat as his body stretched obscenely around Alastor's cock. He didn't stop—didn't breathe—just pistons his hips forward again, chasing that delicious tight heat like a starving man.

 

Lucifer moaned against Alastor's lips, the way the cock stretched in him as he felt so full—his eyes fluttered and his pupils rolled back, his hands falling against the sheets as he whimpered against Alastor's lips when teeth scraped his own. He opened his mouth obediently, letting Alastor's tongue plunge inside to match the filthy rhythm of his hips—the dual invasion overwhelming, perfect. Every drag of Alastor's cock burned, the stretch bordering on pain before tipping into mind-numbing pleasure, and Lucifer arched desperately, his tail lashing against the mattress.

 

Alastor then felt himself lose the sense of cautiousness, finally, pulling himself to go faster, moaning at the way Lucifer squeezed against every drag of his cock—his claws dug into Lucifer's thighs, the sting grounding him as he fucked into that tight heat with reckless abandon. The wet sounds of their coupling filled the room, mingling with Lucifer's broken moans—Alastor's ears twitched wildly at each one, drinking in the symphony of pleasure he'd wrung from his king. "So tight," He growled against Lucifer's throat, "Like you were made for me—fuck—" His hips stuttered as Lucifer clenched around him.

 

Lucifer moaned and whined shamelessly, his voice cracking on every thrust—his fingers scrabbled at Alastor's shoulders, blunt nails digging crescents into his skin as he gasped. "Al—Al—please—" His golden eyes rolled back, tears gathering at the corners as Alastor's cock brushed that perfect spot inside him again and again—his tail thrashed wildly against the sheets, wrapping desperately around Alastor's thigh as if to pull him deeper. "Fuck—faster—need it—ah—need you to ruin me—" The plea dissolved into a sob as Alastor obliged, slamming into him with bruising force.

 

Alastor pressed sloppy kisses along Lucifer's jawline between thrusts—his voice a rough, worshipful whisper against sweat-slicked skin. "My beautiful, perfect king—you take me so well, mon cher," One hand slid up to cradle Lucifer's face tenderly even as his hips snapped forward mercilessly, "Every sound you make—every tremble—proof you were crafted for this," His claws traced Lucifer's parted lips before his voice dropped to a growl, "But you'll take more—won't you? Let me carve myself into your very bones until you forget any other touch." Lucifer keened, nodding frantically as Alastor's thumb pressed against his clit in rough circles.

 

Lucifer's golden eyes rolled back—his whole body arched like a drawn bowstring as Alastor's cock hit that spot relentlessly, the dual stimulation of his thumb on his clit threatening to shatter him completely—his thighs trembled violently around Alastor's waist, slick dripping obscenely down their joining with every brutal thrust. "Al—Alastor—" His voice cracked into a sob, "I'm—fuck—I'm gonna—" His warning broken into scream as his cunt clenched like a vice around Alastor's cock, his orgasm tearing through him as his claws shredded the sheets beneath them.

 

Alastor groaned—a deep, guttural sound torn from his chest—as Lucifer's walls fluttered around him with mor after the orgasm that happened, his own hips stuttering instinctively as pleasure coiled tight in his gut. His claws scraped down Lucifer's thighs possessively, leaving faint red trails that would bloom into bruises later—his breath came in ragged pants against Lucifer's collarbone, "That's it—take it, mon roi," He snarled, voice wrecked, "Come all over my cock like the greedy little thing you are—" He slightly moved Lucifer forward, keeping the pace as the cunt wrapping around him milked him with every thrust.

 

Lucifer whimpered weakly—his body still twitching from the force of his orgasm—as Alastor's relentless pace dragged oversensitive nerves back toward the edge. His golden eyes fluttered shut, tears spilling down his flushed cheeks as he gasped, "Al—too much—'s too good—" His thighs trembled violently where they hooked over Alastor's shoulders, his tail curling limply around the demon's wrist as if begging for mercy even as his hips lifted greedily into each thrust.

 

Alastor's breath hitched—his claws digging deeper into Lucifer's thighs as he felt that tight heat clench around him again—his grin turned feral as he leaned down to lick a tear from Lucifer's cheekbone, "Oh mon cher," He purred, voice thick with lust, "You'll take more—you begged for me to ruin you, didn't you?" His hips snapped forward sharply, punctuating each word with a brutal thrust that had Lucifer's back arching off the mattress with a punched-out moan.

 

Lucifer's golden eyes rolled back—his entire body trembling, his fingers scrambled for purchase against Alastor's shoulders, "F-fuck—Al—I can't—" His voice cracked into a sob as another wave of pleasure crashed over him, "Too full—'s too—ahdeep—" His thighs twitched violently around Alastor's waist, slick dripping obscenely down his thighs with every filthy thrust.

 

Alastor snarled—his own climax coiled tight in his gut—as he watched Lucifer unravel completely beneath him, the king's golden eyes glazed and unfocused, lips swollen from desperate kisses. His claws scraped possessively down Lucifer's trembling thighs, leaving faint red trails that would bloom into bruises later—his thrusts turned erratic, hips stuttering as pleasure burned through his veins like wildfire. "Look at you," He growled against Lucifer's sweat-slicked collarbone, "My perfect, ruined king—coming apart on my cock like you were made for it."

 

Lucifer sobbed brokenly—his entire body convulsing as Alastor's cock dragged mercilessly against that sweet spot inside him—his golden eyes rolled back, tears streaming down his flushed cheeks as he gasped, "Al—please—gonna—fuck—gonna come again—" His thighs clamped down around Alastor's waist, his cunt fluttering wildly as his second orgasm crashed over him with devastating force, his scream muffled against Alastor's shoulder.

 

Alastor groaned—a deep, shuddering sound—as Lucifer's walls clenched around him like a vice, his own hips stuttering wildly as pleasure coiled tight in his gut. His claws scraped down Lucifer's back possessively, voice ragged with worship, "That's it—take it all, mon roi," He snarled before burying himself to the hilt with one final thrust, spilling inside Lucifer with a broken gasp—his teeth sinking into the king's shoulder as waves of ecstasy tore through him.

 

Lucifer arched violently—his golden eyes rolling back as he felt Alastor's hot release flood him—his own climax prolonged impossibly by the sensation of being filled so completely. His tail lashed wildly against the mattress, claws digging crescent moons into Alastor's shoulders as he sobbed, "Al—Alastor—" His voice cracked into a whisper, "You—fuck—you—oh Al—" Before collapsing bonelessly against the sheets, chest heaving. He could feel the cum spilling out of his cunt as he looked at it going down his thighs.

 

Alastor softened his movements as he noticed Lucifer's oversensitivity, slowing to gentle rocks instead of harsh thrusts—his claws retracted completely as he cradled Lucifer's trembling thighs, pressing feather-light kisses along the inside of one. "Was I...good?" He murmured against sweat-slicked skin, voice uncharacteristically tentative—his chest still heaved from exertion, ears twitching nervously. "Did I—ah—did I hurt you?" His fingers traced the fresh bite mark on Lucifer's shoulder with obvious guilt.

 

Lucifer's laughter came out breathless and wrecked—his golden eyes fluttered open to meet Alastor's gaze, his fingers weakly carding through damp hair. "You idiot," He rasped, pulling him down for a messy kiss that tasted like salt from their saliva, "I just came twice—you ruined me spectacularly." His tail flicked weakly against Alastor's hip, still twitching with aftershocks. "Now get up before you crush me, you overgrown deer." The insult lacked any bite, his smile lazy and sated.

 

Alastor smiled in response before he pulled back, not minding the cum dribbling out as he did so—he moved Lucifer to the side, pulling him into a tight hug as his face nuzzled into the crook of the king's neck, kissing the sweat-slicked skin soothingly. "Overgrown?" He murmured against Lucifer's pulse, "I thought you loved this deer being around you." His hands traced idle patterns along Lucifer's spine, claws retracted completely—just warmth and lingering possessiveness.

 

Lucifer huffed a laugh, draping his arms lazily around Alastor's shoulders—his tail curled loosely around Alastor's thigh as he nuzzled back, golden eyes half-lidded with contentment. "Never mind you’re like a cat now," He teased, fingers threading through Alastor's hair, "All clingy after you've had your fill. Not that I'm complaining." He made no move to push away, instead sighing as Alastor's warmth seeped into his sore muscles.

 

Alastor nipped lightly at Lucifer's pulse point—not hard enough to break skin, just enough to feel teeth—before laving his tongue over the spot soothingly. "Perhaps I simply enjoy spoiling my king," He murmured, one claw tracing idle patterns along Lucifer's spine, "Though I do wonder... would you prefer me to fetch a cloth for this mess?" His fingers brushed lightly over the sticky trails between Lucifer's thighs with a slight concern.

 

Lucifer exhaled through his nose, golden eyes fluttering shut for a brief moment before flicking his fingers—in an instant, the sticky mess between his thighs vanished, replaced by the soft weight of an oversized cashmere blanket draping over them both. "There," He muttered, nestling deeper against Alastor's chest, "Now neither of us has to move." His tail flicked lazily beneath the fabric, curling around Alastor's ankle.

 

Alastor chuckled, pressing another slow kiss to Lucifer's temple as his hands continued their idle tracing along the king's spine—his claws barely ghosting over skin. "Already tired, mon cher?" He murmured, pulling back just enough to study Lucifer's face—his thumb brushing a stray tear from the king's flushed cheek. "Not complaining, of course—just admiring the view." His fingers resumed their rhythm against Lucifer's back, alternating between light scratches and soothing circles.

 

Lucifer hummed a confirmation, his eyes closed as he breathed soothingly against Alastor's chest, feeling himself become more tired as he drifted off—before he slipped, he used his tail to pause Alastor's hand that rubbed against his back, before it stilled completely as he finally slipped out of consciousness, his breathing evening out against Alastor's collarbone.

 

Alastor smiled at the press against his hand, watching as Lucifer fell asleep in his arms. He slowly raised his hand, placing it against the king's neck and pressing another kiss to Lucifer's temple as he murmured, "Je suis heureux que nous ayons fait ça ensemble..." Before finally closing his own eyes, his breathing synced with Lucifer's as sleep claimed him minutes later.
