Chapter Text
Alastor had a problem. That problem looked like an irritating short king who had the smoothest skin and the most kissable lips imaginable. The radio demon had never felt this way before, and he had no idea how to handle it. Both his instincts as an animal-like demon and as a ruthless, selfish psychopath kept yelling at him to take, take, take. To just take and never let go. But he was better than that.
Or... at least that's what he thought.
No matter how much Alastor wanted to act like he was superior to his baser instincts, he was still just a man. A man who felt like he would explode if he didn't get his hands on Lucifer soon.
That is why he found himself here, in front of Lucifer's bedroom door, in his quarters, far away from any other resident's room.
Resolute, Alastor opened the door to Lucifer’s chamber, ignoring the sign pointedly directed at him to stay out. As he entered, he was greeted by a sight that would be graved into his brain forever and ever.
The King was sporting an oversized shirt that had climbed up his stomach, showing off the pale skin there, as well as lacy red panties.
“Lord…” He sighed, trying his best to control himself. Before he could indulge, he had to make sure of something. Alastor headed to Lucifer’s bedside table to peek into his cup. He smiled as he saw that its contents had been completely drunk by the blond, who had unknowingly consumed the strong soporific that Alastor had mixed in with his hot chocolate. For once, the array of medication the spider resident brought in from his boss proved to be useful.
“Perfect.”
Assured that Lucifer wouldn’t wake up until it was too late, Alastor headed back to the bed, climbing over the small man’s sleeping form.
He felt as if he would double-die if he didn’t have his cock fucking into the King’s womb right this instance. Not wanting to lose any more time he could’ve been using to fuck Lucifer, he turned the sleeping blond around to lay on his stomach, heart fluttering at the soft sleepy sounds coming out of the other’s mouth.
Raising Lucifer’s ass higher, he couldn’t help but play with the adorable underwear for a few seconds, harshly pulling on it to see the fabric bunch up into a line in between the King’s pussy lips.
“Fuck… So gorgeous.”
After a few more seconds of pulling and listening to the soft whimpers coming out of the blond's mouth when the fabric would harshly rub on his clit, Alastor took off the panties, throwing them carelessly to the side to hopefully retrieve later for his own personal purposes.
He took off his jacket and quickly opened his fly, yanking his pants and underwear down only as much as necessary to pull his cock out. It was hard and throbbing, showing its impatience.
Alastor contemplated prepping Lucifer for a second before deciding it would just be a waste of time, he knew Lucifer could handle him. And even if he couldn’t, that wasn’t his problem anyway, Lucifer would learn to handle him.
With that in mind, Alastor brought his red tip to the blond’s entrance before bottoming out in one fell swoop. “Hrrgh- fuck… So tight… I knew you’d be perfect my dear~” Alastor moaned, he couldn’t believe his luck. To have the King Of Hell at his mercy… If only the blond was awake for this, moaning for him, screaming his name in pleasure… ah~ how beautiful would that sound?
“I guess if I want to be able to hear that sweet melody, I’ll just have to fuck you awake, huh my love?” He murmured, hips snapping against Lucifer’s ass, prompting shaky moans and cut-off whimpers from the sleeping victim.
As Alastor fucked his cock deeper into his belle, he couldn’t help but wonder. “Are you the one to have given birth to our sweet darling Charlie?” He chuckled, his grip on Lucifer’s hips tightening “Ohh… You must’ve been, with a body like yours, not breeding you would’ve been such a waste~”
With a particularly harsh thrust, the idea hit Alastor. He had planned on pulling out originally but… The thought of breeding the King himself? Of Lucifer carrying his fawns, nurturing them and taking care of them, with Alastor as his new husband, it made him go insane.
He was determined now to thoroughly breed the sinful blond beneath him. He could not wait to see Lucifer struggle to move around with his womb full and round with their children.
With the brain melting imagerie now rooted deeply into his mind, Alastor picked up his pace, pounding Lucifer’s pussy like there was no tomorrow. Each time he bottomed out, Lucifer congratulated his efforts with punched-out “ah~”s.
At some point, Alastor lightly lifted his hips for a particularly harsh thrust that hit Lucifer’s cervix. The electrifying sensation seemed to be enough for the blond, moaning mess to wake up with a gasp beneath him, wide eyed.
“AH?!- N-ngh! Wh-what-”
“Shhh sweetheart, let’s make this easier on both of us-” Alastor whispered in Lucifer’s ear before taking both of his wrists in one hand to keep them behind the King’s back.
“N-Ngh! Fuck- Alastor?! What- What is happ- ah! What are you doing?!” Lucifer cried, unable to stop his moans but still actively trying to run from Alastor’s iron grip.
Heaven’s punishment on Lucifer proved to be useful in some instances.
“I’m simply taking what is rightfully mine, don’t worry you’ll- ahh~ you’ll thank me soon…”
“F-fuck! Get the fuck off of me- ah no no- I’ll kill you!” Lucifer groaned, his eyebrows furrowed.
“Tut tut, we both know you can’t do anything to me, but keep it up! Your bravado just makes me want to fuck it out of you even more.” Alastor smirked, quickening his pace, much to Lucifer’s dismay.
“Ahh~ Alas- ngh! Alastor pleasee~! St-stop!” Lucifer pleaded with the sinner.
“Hmm… Fuck, my name sounds oh-so beautiful coming out of your lips.” He chuckled darkly, licking the side of Lucifer’s face.
“H-hrgh! I-I’m begging you please-”
“Love, it doesn’t matter how many times you tell me to stop, I’ll keep fucking you until I’m satisfied, so you should probably just try to enjoy yourself~” Alastor leaned back, desperately trying to hit Lucifer’s womb again.
After a few more seconds of violent thrusting accompanied by Lucifer’s wrecked moans, Alastor’s tip hit the entrance of the little devil’s womb once more.
“AH! Fuck- No no no! Alastor please- You’re already so deep!~” The blond screamed.
“God- you truly know all the right things to say to a man, don’t you?” He sighed ecstatically, feeling drunk. “But I fear I’m far from done Lucifer, just- hrk! Just a little… more!” He grunted, punching his cock against Lucifer's cervix, bruising and pounding it. Finally he was able to push his cock past the stubborn barrier and started fucking Lucifer’s womb in earnest, seeing stars. “Fuckk~”
“AH FUCK! Nooo~ Alastor this.. this isn’t- ngh! Too too deeeeep~! I’m gonna diee!” Lucifer sobbed, he felt like Alastor was tearing him apart.
“You’re so good for me Lucifer, I’m never letting you go!~” The sinner moaned, blissful. “Gosh~ You’re going to look so good, full of our children…”
Suddenly Lucifer froze “Wh-what? You’re planning on ngh-! N-no Alastor please! I can’t! I… I don’t want to!” He cried, begging for the other to not impregnate him.
“Hmm? Ahh… I see… Such a shame that you don’t have a choice in this, hm?” Alastor smirked, drinking in the horrified look on Lucifer’s face. “Ohh, don’t look so blue darling, you’ll learn to love it, I’ll make sure of it. By the end of this night, you will be begging for more children to be pumped in your womb, don’t worry~” He purred before bringing his hand down to play with Lucifer’s neglected clit.
The fear on the blond’s face quickly dissolved into an expression of pure ecstasy, thighs shaking with the dual stimulation. “AH! N-no fair!”
Alastor’s grin broadened as he chuckled drunkenly “There we go… Just let it all out.”
Meanwhile, Lucifer's eyes widened with unwanted but overwhelming pleasure. “N-no no noo~!” He whined as he came suddenly, his back arching as best as it could.
With his climax, Lucifer tightened considerably around Alastor’s cock. “Fuck- so… So tight-! ngh!” With a few additional erratic thrusts, Alastor came deep inside Lucifer, painting his womb white.
He watched as Lucifer trembled under him. “Good… So good for me.” He sighed before bringing a hand to Lucifer’s face to lift his head up far enough for them to make eye contact...Or more-so for Alastor to make eye-contact considering Lucifer’s gaze seemed lost, brows bunched up as drool seeped out of his mouth. “You’re so beautiful…” He kissed Lucifer’s sweaty forehead before letting his head fall back down onto the mattress.
Not worried, Alastor let go of Lucifer’s wrists, instead patting the blond's hair as the other moaned weakly, still feeling the aftershock.
“Now Lucifer, did that feel good?”
“Ahh… Hahh… I..”
“No need to respond actually, I already know the answer.” Alastor chuckled, bringing a hand down to Lucifer’s stomach to press down onto the outline of his cock.
“Ah?! A-Alastor… T-too much, oh my God…” The devil moaned weakly, his insides tightening once more around Alastor's quickly hardening dick.
“Hmhm, how does everything I promised you sound now?”
“H-huh?” Lucifer dumbly muttered, he felt like his brain had melted out of his ears.
“How does carrying my fawns sound? My sweet doe, I promise you, you’d be so much happier if you just gave in.” Alastor kissed a stray tear rolling down Lucifer’s cheek. The blond hated how the gesture made his insides feel warm. “You won’t have to worry about anything else, you can just let me fuck every worrisome thought out of your pretty little blond head, alright?” He sweetly said as he thrust harshly one time, prompting a surprised moan from Lucifer. The King could feel the way Alastor’s cum was sloshing around inside him, tarnishing any rational thought he could’ve possibly had.
“W-With Charlie it…”
“Hm? It felt good didn’t it? Didn’t you like being pregnant with Charlie? Being so close to your child?”
“It.. mmh! It did feel nice...”
“Here we go. I could impregnate you as many times as you’d like, making sure to protect you and our fawns. How does that sound? Handing over all the stress in your little head over to me, the only thing you’d be feeling is pleasure, with me fucking you as much as you’d want to, making you carry our children over and over again… You wouldn’t have to worry about anything~” Alastor finished, bringing a hand down to rub at Lucifer’s reddened clit once more.
“AH! ah ah ngh! S-sounds… Sounds good…” Lucifer moaned, hands coming to clasp at Alastor’s arm.
“Ohh my stupid stupid adorable baby. You won’t have to worry about anything else from now on~” The sinner laughed before wrapping his arms around Lucifer to lift his torso up from the bed, bringing his back flush against the sinner’s chest.
He then summoned his tentacles to wrap around Lucifer’s arms, tying them behind his back once more. “Here we are, aren’t things so much easier when you surrender control?” Alastor whispered in Lucifer’s ear before picking up his previous pace, the new angle allowing him to fuck his cock further into the blond’s fertile and awaiting womb “You weren’t made to be in such a stressful position of power sweetheart~ You were always meant to be nothing other than a breeding moor for me, happy and content without single thought in your head as I impregnate you endlessly hah..~” Alastor groaned in tandem with Lucifer's ecstatic moaning.
“Ah ah ah! Ngh! Fuckk yeeesss~” The blond whined wantonly.
“Who’s my stupid little fuck hole?” Alastor sneered.
“Ah! Me me! Fuckk~ Alastoor~”
He couldn’t believe how far gone the little King was, here’s to infinitely more nights similar to this one.
“Good boy.” Alastor groaned, the arms surrounding Lucifer tightening as he fucked into him harshly, the blond’s head laying on his shoulder with a fucked-out look on his face. “Go on, tell me what you want from me, my love.”
Lucifer ignored the way his heart skipped a beat each time Alastor used a romantic nickname for him and answered cock-drunkenly. “Fuckk~ Pleasee please, I want babiess Alastor~! *hic*!”
“Oh yeah? You want my babies?”
“Yes yes yesss~! Pleasee, I need thiiis!” The King cried, eyes rolled back, any trace of former glory completely gone.
Fuck. Alastor wasn’t sure how long he could last with Lucifer moaning in his arms, begging for his seed.
“Oh~ Who am I to refuse you? Don’t worry, I’ll be pumping you full of new fawns to keep our earlier load company~” He grunted, one hand coming to rub Lucifer’s red clit while the other laid flat against the blond’s distended stomach.
“Fuck fuck pleasee~! Ala- ngh!”
“Now, now, once our fawns are born, you’ll have to watch what comes out of your mouth, can’t have them hearing their mother cuss like a sailor can we?”
“R-right! I’m- I’m sorry ! Ngh! I’m sorryyy- Ahh!” Lucifer profusely apologized, full on sobbing by now.
“Ahh- don’t worry dear, we’ll have a few months to work on that, no matter how stupid and cock-brained you may be, I’ll help you learn~” Alastor kissed his sweaty temple, prompting more sobs from the blond who could not deal with the influx of feelings banging inside him.
As the two of them felt their climax approaching, Alastor quickened both the pace of his hips and the rubbing of his hand on Lucifer’s sensitive clit. The once proud King had been reduced to nothing more than a slut desperate for the radio demon’s seed. The latter couldn’t take his eyes off the look on Lucifer’s face, covered in drool and tears, cheeks rosy with his eyes rolled to the back of his skull and his tongue lolling out.
His doe looked perfect.
The sight of the future mother of his children looking so fucked out sent him into a frenzy. Alastor’s pace became erratic, making Lucifer cry out as his climax hit him like a truck, squirting all over the sinner’s hand, the liquid dripping down his thighs and onto the mattress. Lucifer’s squirt hitting his hand and the wanton noises that came out of the blond alongside it was what ultimately pushed him over the edge, groaning animalistically as he pumped his load deep into Lucifer’s womb. Pump after pump, Lucifer’s stomach started expanding with the unnatural amount of cum being churned into him.
“O-Oh my God… ahh~ngh!! S-so muchh haha..” Lucifer laughed, stupefied.
“Ahh…hah… Oh Lucifer, you truly are God’s greatest gift to existence.” Alastor sighed in his hair, his hands petting Lucifer’s stomach. “Look at this,you already look full with my children hah! Here’s to hoping this swelling never dies down.” He purred, licking the side of Lucifer’s neck before bringing his hands to the blond’s shaking thighs to lift them in the air, picking up his belle.
“Ah?! Wh- Al? Ngh!” Lucifer moaned, the position plunging Alastor’s cock even deeper than he thought was even possible. Once again his assumptions were wrong, the sinner really was right in saying his stupid little brain shouldn't try to think anymore and just rely on his Alastor.
Alastor laughed at Lucifer's confusion “Wh-ahahat ? Did you think only two pumps of my seed would be enough? We’ll keep going until you can’t lay flat on your stomach sweetheart, understood?”
“Ngh! Aha Yeess yes yesss!” Lucifer giggled, a stupid smile on his face.
Alastor had done his job well it seemed.
The rest of the night was animated by pleasured screaming from Lucifer as the only feeling he could even focus on was the one of Alastor’s cock head hitting the back of his womb as well as his stomach inflating with cum. They had moved from the bed, to the ground, to Lucifer’s desk and back to his bed, their bodies contorting into any position they could think of.
After over 3 hours of incessant breeding, Lucifer’s brain could not take any more and the blond passed out under Alastor. After pumping two additional loads into an unconscious Lucifer, the radio demon decided to call it quits for today.
As much as it pained him to do so, Alastor brought Lucifer into the King’s personal bathroom to eject all the cum he had pumped into him, pressing on his stomach in the bathtub. He knew that his seed had taken by now so cleaning out Lucifer wouldn’t have any real effect on his goal of breeding him, however it still stung to make that round stomach disappear. Nonetheless, the idea of poor Lucifer convincing himself everything was a dream as every trace of their encounter disappeared and then continuing on with his life without a care in the world until he one day realized he had been knocked up… It sounded glorious. Oh the look of panic that would be on his face a few weeks from now once he realized the violation he had dreamt about had actually happened and that he was now actively bearing the radio demon’s fawns, Alastor couldn't wait to see it.
After finally cleaning up Lucifer, as well as any other residue they may have left behind, Alastor searched for another underwear he could put on the blond to not leave him bottomless, as it may raise his suspicions. He found a pair of lacy panties that looked similar to the previous pair, only these ones were black.
“Good enough.” He thought as he put them on Lucifer’s unconscious body, taking the red panties that he had thrown aside earlier to put in his pocket.
Finished for the night, Alastor retreated back to his quarters.
“Hmngh… Fuck…” As the sun rays hit Lucifer’s face, the blond tried to get up but found himself wincing at the way his lower back and shoulders hurt, not to mention his thighs. “Ow ow… The hell?” Lucifer blinked as images of Alastor fucking him every which way flooded his mind. “Oh my God.”
Immediately, the King went to check in-between his legs, panicked. However, instead of finding anything incriminating, his pussy was as clean as it should be, no traces of… a certain man’s visit. “W-What…? But I could’ve sworn he…”
Had he just had a very weird and fucked-up sex dream? Lucifer looked around before noticing the underwear he was sporting. “Black?” He could’ve sworn he had worn red panties to bed… Then again, he was never known to have a good memory.
Shaking any weird thought out of his head, Lucifer got out of bed, ignoring the way his muscles were screaming at him to lay back down. “In what position did I sleep last night? Christ…” He stretched before putting on his characteristic outfit and leaving his room to greet his daughter.
As he arrived in the lobby, he saw Charlie discussing decoration plans with the sinner from his dreams- or urh- nightmare?
His daughter quickly noticed Lucifer's arrival and ran to him, followed by Alastor. “Hey Dad! How did you- Ouhh... I was gonna ask how you slept but uh-”
“I look like a mess?”
“Kinda, yeah” She chuckled.
“Yeah, I sure feel like one too hah… I don’t know, must’ve slept in an awkward position I guess.” Lucifer sighed, smiling up at his darling daughter but still throwing occasional glances at the sinner that was standing next to them.
Alastor was acting so normally… It must’ve been a dream. God, he really needed to get laid if he was starting to have sex dreams about his daughter’s friend and his sworn rival.
“Hm? If you ask me, the King still looks as positively awful as he always does!” Alastor laughed despite the annoyed look he got from the two blonds.
Yeah, it absolutely was a dream. Especially considering Alastor couldn't stand him. Plus, there was no way the sinner would’ve ever partaken in such debauchery when he barely supported someone grazing his arm.
“Come on Al, lay off my dad for once!” Charlie scolded him, though the kindness never left her sweet voice.
He was happy to have such a wonderful daughter. Charlie was a perfect mix of some of both his and Lilith’s best characteristics. Absentmindedly, He wondered what a child with his and Alastor’s quirks would be like- wait what the fuck was he even thinking about?! God he really needed time away from the bellhop after that dream, it was messing with his mind.
It was only a few weeks later when he found himself curled up in front of his toilet in the early hours of the morning, vomiting everything he had eaten earlier that he thought back to the red-headed demon.
“If only Alastor were here…”
It was as if his instincts were crying for the sinner to come take care of him. He remembered having similar thoughts about Lilith at the start of his pregnancy with Charlie... It was like he was… Oh no.
