Morningstar!Reader x Alastor
—————————————————————————————————
You were the King of Hell’s treasure.
You were the older twin to Charlie Morningstar.
Because you were the firstborn Princess of Hell, your father had arranged that you would marry and begin the process of becoming the next ruler of Hell.
“What?” You asked confused looking at your father, not sure you had heard him right.
Lucifer cleared his throat and had a big smile on his face.
”I have finally found a respectful hellborn for you angel. A Goetia prince. Hes perfect for you and would make an excellent partner”
Marriage?
“But Daddy I-” you started, but Lucifer interrupted you
“No but’s it took me a longtime to find someone who I thought would be a good match for you. This is good! I already have everything arranged and it has been set. As the Princess of Hell you will begin your royal duties officially”
Charlie took your hand as you felt your anger rise. Being the kind soul she was, she tried to intervene
”Dad sis is already in a relationship. She can’t just give that up. She’s in love” your twin gushed.
Lucifer grimaced at the mention of your significant other.
”Yes Alastor was it? Hmm well I advise you make peace with him and end it.”
You felt tears pool in your eyes. Give up your love? This was so unfair!
“I will grant you six months. One year to make your peace with the bellhop and then you’re coming home. Understood?”
You nodded sadly as you stood and bowed “Yes father”
You watched as he opened a portal and disappeared, leaving you and Charlie.
Charlie turned to you “Hey Im sure if you explain to this prince your situation that he will understand” Oh sweet Charlie. So naive.
You shook your head “You dont understand Charlie. I have a duty to uphold. I am the Heir to the throne and I must obey our father’s wish. As ordered by the King”
You stood up and went to your room, where you cried yourself to sleep.
—————————————————————————————
Hell was in a frenzy at the announcement of your upcoming engagement.
It wasn’t everyday that hellish royalty was getting married.
It was the talk in all the rings of Hell.
And soon word reached back to the Radio Demon.
You and Alastor had been going steady for a while. It was actually your twin who encouraged you two to be together since Alastor had made it known he had fancied you when you came to the hotel to help your sister.
You never imagined you would be head over heels for the red demon, but satan did you love him.
Alastor adored you. Worshiped the ground you walked on and treated you with the upmost respect.
There was no way you could just break up with him to…to marry a stranger!
You had always thought you would marry Alastor. But maybe that was just a dream….
”The realm is buzzing with excitement. Never thought your father would disapprove of our union so much” Alastor chuckled.
He had brought you out on a date, to distract you from all the fuss.
It was just you and him. Just as it had always been.
You stiffened. You hadnt had the heart to tell Alastor of your father’s decision. You just wanted to enjoy these moments while they lasted.
You sighed, poking your food “Are you upset?” You asked softly, peeking at him through your eyelashes.
Alastor smiled, “Well you are the princess my dear. Im not upset. Ill love you even if you decide to go through with this whole engagement haha but I hadnt added a prince to my broadcast yet” he giggled, making you smile.
Oh how you loved his bloodlust.
”j-just…I mean I haven’t even met this guy and daddy just wants to ship me off to the highest bidder. There hasn’t been any need for him to even think of marriage. Hes not dying. There’s no need for me to marry. I dont want marry a stranger…I want to marry you”
”Oh my dear at least let me be the one to propose” he joked.
He grabbed your hand, rubbing your knuckles with his thumb “Dont worry dearest. I wont let anyone take you from me”
————————————————————————————-
The hotel was quiet when you two came back.
You had indulge in drinks to rid your mind of your impending doom.
Alastor brought you to his room and you made yourself comfortable.
Like any date, you hoped to lose yourself in pleasure at the end.
You stripped yourself of your pantsuit, leaving you in your lingerie.
Alastor’s colors.
”Red is such a lovely color on you” He whispered, coming behind you, pressing soft kisses on your shoulders. You hummed happily, turning around to wrap your arms around his neck. You were blessed with your mother’s height so your breasts were hugged against his face.
”I can give you anything you desire ma cherie. Say the word and its yours. Ill burn Hell if you say to. I am at your complete disposal” He peppered your chest in kisses, softly nipping at the tops of your breasts.
You leaned his face up to yours and pressed your lips against his, pulling him into a passionate kiss.
”make me forget all my problems. Fuck me like the slut I am and not a princess. I wanna be yours completely, like we have forever” you whispered against his lips.
Alastor grinned as he retreated from your lips, trailing a hand into your thick locks and gripping tight, the other toying with your panties.
”Your wish is my command”
—————————————————————————————
“F-fuck! Please please” you whined, as Alastor pounded into you.
Your claws ripped through the bedding as your body jolted along the sheets. Your body was going haywire.
How many times had he brought you to orgasm?
You had lost count.
Your body was sticky with sweat and your cunt clenched around his cock.
Alastor tugged your hair, pulling your head back. He let out a growl when he saw how fucked out you were.
Your face was flushed, your tongue lulled and you were panting.
So beautiful.
”A-Al!” You cried when he gave you a harsh thrust. He chuckled “what is doll? C’mon use your words”
words? What were words? You could barely think!
He leaned over you, never breaking his pace ”what a pretty slut. To think another demon is to fuck my cunt. No that wont do. Your cunt is mine and I wont let another have the pleasure to carve it. You always take me so well baby. What’d you think dear?”
You let out senseless babble as your cunt fluttered.
Your cunt let out a squelch as he pulled out. Alastor’s cock was coated in creamy slick. You whined, pushing your hips back to try and have him fill you again “No no no gimme-”
Alastor sucked his teeth at you, smirking “oh? You want my cock? How bad you want it hmmm? Soon it wont be me feeding you cock every night” he slapped his tip against your slit. You moaned, wiggling your hips. You pouted “I dont want another cock Al! I-I want yours! Only yours please”
He released your head,making you fall forward. You spreaded your thighs and leaned back on your knees as you dipped your hand to your dripping cunt.
You looked over your shoulder at him as you toyed with your puffy clit. Your lips jutted out in a pout “p-play with me. I want it! I want your cock so bad. Please please fill me up. I want your cock to be the only thing to fuck me ah! Alastor!” You felt that band of tingles form ready to release.
But you couldnt cum. Not without Alastor.
He knew your body better than you did.
Alastor slapped your hand away, having mercy on you.
”The pretty princess can’t cum can she?” You whimpered as he chuckled, sliding his cock against you.
Alastor felt that familiar burn in the pit of his stomach.
Possessiveness. Jealousy.
He rarely had the urge to fuck you into submission.
“Fill you? Oh baby when I’m done with you you’ll be dripping with my cum.” He let out a dark laugh as his body morphed.
Your heart thumped in your chest as you watch Alastor transform into his demon form.
”roll over” his tone was dark and sharp, leaving no room for debate.
You rolled onto your back obediently, spreading your thighs and bringing your hand back to your clit.
You moaned softly as you rubbed tight circles on your bud.
Large clawed hands massaged your plush thighs.
His bright eyes focused on your fingers.
His chest rumbled as he lowered his head to your cunt, nipping at your fingers. “This cunt is mine. My cock is yours. You think some prince can fuck you half as good as me? Oh no. Not the cunt I worked so hard to carve into.” He licked at your clit, dipping his tongue into your tight hole.
”My personal royal fucktoy that’s what you are doll.”
You moaned softly at the degradation, rolling your hips against his face.
Satan he knew how to get you going. Alastor’s demon form was terrifying to most, but you found it hot that you made the Radio Demon lost himself to the point he could let loose.
Static buzzed your skin as Alastor ate you as if meaning to devour you whole. Alastor released your clit with a pop, opting to nuzzle the pearl before hooking a hand under your knee, lifting it to your chest, opening you up.
Alastor leaned up, wedging himself between your thighs. Your eyes drifted to his cock.
Youve fucked the red demon in his demonic form before, but it never ceased to amaze you the sheer size of him.
You felt your body heat up as your own demonic form came to the forefront, wanting to accommodate the male on top of you.
Beautiful vermillion horns sprouted from your hair as your eyes turned red and sharp. Your spiky tail swished, hitting Alastor slightly making him narrow his eyes at your playfulness.
You were so pretty.
Alastor leaned his head down, neck cracking to nudge your face, nose taking in your scent and sharp teeth nipping at you. Your dainty claws found purchase in his fluffy locks, making way to paw at the massive antlers sitting on his head.
A soft gasp escaped you when you felt his heavy cock press against you.
Your eyes met his.
Red dials simmered with desire, but you could see the love he held for you, even like this.
Alastor would do anything for you.
Were you to really turn your back on a man who would carve his heart out if you asked?
You pushed yourself up against him, affectionately kissing his neck and shoulder, scraping your sharp teeth against his skin.
“I love you Alastor” you whispered, feeling your cheeks burn as you admit this suddenly.
You and Alastor never expressed how the two of you felt with words. Actions were more appreciated, but you felt like you should at least tell him once.
He chuckled slightly “No need for such a declaration my dear. Youve had my heart and soul since the moment I saw you. You have my utter devotion.”
He purred. Your eyes widened as a thought popped into your head.
Soul?
Alastor has given you everything of his without even a contract.
His love.
His heart.
His soul.
They were all yours willingly.
”Make a deal with me”
Green magic swirled at your words and Alastor’s cock twitched, he growled lowly “Careful with what you ask dear”
You ignored him. Your hand drifted between you and you gasped as you slid his cock into you, making the demon let out a room-shaking growl.
A surge of magic washed over you and you watched as the glittery glow seeped into Alastor’s skin.
A full thrust had you taking him to the hilt, balls flushed against your ass.
Alastor bared his teeth at you, his tongue licking your cheek.
”My heart and soul…I give it to you” at your words he snapped his hips against yours.
”My complete devotion and love will never waver, for i chose this of my own free will”
Your claws hand sunk into his back, you were trying to focus.
”As a princess of hell and heir to the throne, I grant you any desire you wish…Ah!…”
A soft golden glitter mixed with the green magic, popping noises filling the room.
Alastor's hand was around your throat, holding you into the bedding as his cock pounded that sweet spot inside you.
The hand holding your thigh, was damn near pushing it to be beside your head, opening your cunt to his merciless pounding.
”Al!” You cried.
”You” he hissed lowly, you almost missed it up.
”I want you. I want you to be my mate, as you should be. I want to see you swollen with my seed, ma cherie. To be properly mine and claimed.”
Your magic surged and Alastor’s hips faltered when he felt your cunt fluttered and squeeze around him.
He felt the warmth of your magic in him and moaned as he pushed into you.
“You’re gonna let me fuck a spawn into you? Gonna let me ruin this royal womb? Oh what a treat you would be, a hellish princess carrying the Radio Demon’s spawn oh hoo ”
He crackled as you arched, mewling as his pace grew harsh.
”O-oh fuck! Fuckfuck! ah ah AH ha a-a-h Al!”
A red mark graced your lower belly, the royal seal.
It prevents you from being impregnated.
But with each drag of Alastor’s cock and magic, you watched as pieces disappeared.
“C’mon baby loosen up. I wanna make sure you take all my cum. Dont want a single drop wasted”
He rolled over, catching you off guard. You blinked down at him as you sunk down onto him.
He shot you wicked smile, fluff wild “Just wanna see when you fall apart on my cock”
He thrusted up and you keened, bracing yourself against his chest.
You were gorgeous as you rode the demon. Red horns like a crown as you threw your head back in pleasure.
Alastor wrapped your tail around his arm and growled when you pushed down on him.
Whipped cream gathered at his as you dragged your walls over him, throwing your assinto his thrusts
”pretty pretty princess. Such a slutty pussy that wants to be filled. that’s a good girl, you take my cock so well doll. You want my cum?”
You whimpered, nodding “yes yes yes please cum in me. Breed me. O-Oh ha! Al! Let me have your babies please OH fuuuuuccckkk I want it I want it so bad.” Your claws played with your clit, making your orgasm buzzed, golden magic sparking.
You let out a sharp cry as your back arched. Alastor dug his claws in your hips and pounded you out until his cock twitched and the mark on your belly melted away.
Your cunt squelched and your back burned.
”Fuck fuck fuck!”
Alastor growled as his cock dumped his cum inside you.
You crashed against Alastor’s chest, large wings erupting from your back, shielding the two of you in a cocoon.
You tried to move your hips, but Alastor held you fast as rope after rope of creamy spunk painted your walls.
He had returned back to semi-normal. He pressed a kiss to your forehead “Fuck darlin such a good girl.”
You purred as you changed back.
You ran a hand over your belly, blinking to find it was bulging softly.Alastor chuckled “Seems I might have overdid it just a bit”
You nuzzled into his neck “Mhmm not quite…” you sunk your fangs into his neck, making the demon hiss and bite into your shoulder.
You gasped as you felt the last restraint snap and his cum flood your womb, you wiggled your hips, milking his cock.
Alastor let out a hum “ So perfect and all mine.”
You giggled sleepily. “hmmm.”
Your soft snores filled the room.
Alastor’s ears flicked as he watch little flecks of magic danced around the two of you.
He felt kind of bad for having you cockwarm him so he slid himself out. The magic swirled around your womb, sinking into your skin. He watched in wonder as your bulge slowly went down and a soft glow shone where your mark was.
Wonder what that was about?
————————————————————————————
“Oh my gosh! Look at you! Your horns! You look like mom. Oh Satan Dad’s gonna flip” Charlie said as she pressed her hands against your swollen belly.
You chuckled at your sister. You could handle your father.
The hotel was shocked when you had announced you and Alastor were having babies.
yes.you heard right.
Babies.
Two!
Twins.
Alastor couldn't be more smug when the two of you walked around the city. He was very entertained by the whispers and stares that were thrown around.
The Princess of Hell was having the Radio Demon’s spawns.
Isnt the Princess engaged?
How dare he?
How is the king gonna react?
This will bring shame to the realm!
You were six months and soon your father will be coming to take you to meet your ‘betrothed.’
—————————————————————————————
Your tail swished in annoyance as you crossed your arms, staring at your father.
The Goetia Prince looked between you and Alastor nervously, Alastor flashing him a sharp smile as he wrapped his arm around your waist.
Your father was seething.
Horns standing tall, eyes red, a ball of fire raging, wings and tail out, and ahh the seraphim eyes.
Daddy was piiiissssed.
And you didnt care.
”what the actual FUCK?!” He bellowed, eyes narrowing on Alastor.
”YOU DARE SPAWN WITH MY DAUGHTER?!”
Alastor hugged you into his side, grinning like a little shit as his hand caressed your swollen belly.
“She was quite adamant Your Majesty. Who am I to disobey my Princess?” His grin had flames pooling from your father’s palms.
You cleared your throat, addressing the Goetia “You can go back home. The marriage is off” the demon blinked and looked to your father.
“Angel you dont understand-”
”No daddy you don’t understand! If you can be casted from Heaven for love, why can’t I rule Hell with mine?”
Lucifer faltered, eyes dimming.
He watched as Alastor comforted you, pressing a soft kiss to your forehead. He looked at you the way Lucifer looks at your mother.
With complete and utter love, adoration,and devotion.
His eyes drifted to your stomach.
You were pregnant and happy.
Lucifer sighed and approached you, making your horns curl in warning.
Lucifer looked at you.
You looked just like Lilith. You were happy and so in love.
He sighed seeing the ring on your finger.
He wondered where you got that stubbornness from?
your mother no doubt
”Fine fine” he sighed, making you calm down.
”I am to be a grandpa it seems! I-I can’t wait.” He smiled at you making you smile back.
”What am I suppose to tell my father?!” Oh he was still there?
Lucifer blinked in confusion and shrugged “Im sure he can overlook this mishap”
”Mishap? Mishap?! Your daughter is a whore! A mockery of He-AAAAHHHHH!”
You smiled happily as Alastor let out a burp “Thank you Al”
He kissed your cheek “No one will insult you in my presence. His screams were exquisite”
Lucifer cleared his throat as the two of you made heart eyes at each other. “Sooooo twin spawns? Yippee”
You laughed rubbing your belly “Things are gonna get busier around here.”
————————————————————————————-
Alastor leaned down to kiss your forehead, looking at the bundle in his arms.
”You did wonderful my love”
You hummed as you rocked the other bundle.
”YOURE OKAY! I was so worried. You were screaming and then we heard nothing” Your sister cried bursting into the room, Lucifer entering behind her. You smiled at your twin’s rambling. Charlie fretted over you before settling on the bundle in your arms.
She squealed “Are they-?”
”Met the newest additions to the family”
You had given birth to twins.
A boy and a girl.
You were holding your baby boy, cooing at the babe who looked at you curiously.
Baby boy was the splitting image of his father, except he had your rosy cheeks and and cute nose.
Baby girl took all after you. Pale skin, rosy cheeks, tuffs of blonde hair and little wings tucked and curled.
Alastor nuzzled your mini version.
“What you gonna name them?” Charlie asked cooing at the babies.
You turned to your father “Alastor and I thought it would be best if you name them dad. You know the whole angelic thing” you smiled.
Your father’s lips wobbled at your words.
Alastor handed you your daughter and you adjusted both fawns in your arms.
Your father placed his hands over them and a soft golden glow appeared.
“The Son of the Morningstar shall be called Abaddon”
Your son giggled as magic danced around him, red eyes glimmering in delight.
You placed a soft kiss on the boy’s fluff and handed him to his father.
”A Daughter of the Morningstar shall be named Azrael”
You snuggled the fussy girl who calmed at your touch.
”The blood of the Morningstar shall be blessed as long as the eternal flame blazes. Amen”
You smiled and let out a tired yawn.
”Alright I think that’s enough excitement for one night.” Alastor rushed Charlie and Lucifer out so you and the babies could rest.
Alastor slid beside you on the bed and used his tentacles to put the twins to sleep.
You leaned against his chest, eyes heavy as you smiled up at him.
”was this everything you envisioned?”
Alastor grinned down at you, before taking a long look at his fawns, he looked back at you and hooked a finger under your chin to capture your lips in a kiss.
”Hmmm its much better my dear. Much better”
