A teen who isolates from social interaction after his ex girlfriend cheated on him with his bestfriend as heads home to do anything to keep him away from everyone as he reads into the occult... weeks later he draws a demonic summoning circle and performs a blood oath instead of a summon revealing a beautiful girl in a black dress as her hair white as snow, with magenta eyes, as her body alluring as she has demon horns and a confused look as she looks around her surroundings before looking at the teenager

Girl: Who are you to summon the Daughter of Satan?

Boy: I summoned a demon using a ritual before casting myself into hell itself!

She looks at the ritual in the open page of the book and blushes as she looks at the human

Girl: Human why did you summon me really your chest beating rapidly!

Boy: Well I have no friends... as my ex bestfriend slept with my girlfriend. Plus I don't have much to live for as my parent's are dead... and I'm a only child.

Girl: Then it settle.... I Princess of Hell Lucifaina Morningstar, will be your friend til your human life over and I take your soul to hell!

She offers her left hand as he accepts it with his right hand

Boy: F/n L/n... I hope my soul worth it?

Lucifaina: Now I should mention that only you can see my demonic heritage as a human... but other things can see me too like Angels! But where do I sleep at?

F/n: My place only has one bedroom and bath...

Lucifaina: Then we sleep together human... it only right as I own your soul!

Few days later

Lucifaina transfers into her friend's school as she wearing a catholic school girl uniform as her bust big for a sixteen year old girl as her mother to blame and when she enters every boy minus F/n spikes in arousal

Lucifaina: Greetings, I'm sorry for transferring late in the year... my name Lucifuge Morningstar!

Teacher: Your name interesting... any hobbies?

Lucifaina: Yes... I enjoy reading books and baking!

F/n looks uncomfortable as his ex friend snickers as he raise his left hand to ask her a question

Lucifaina: If it to ask for a date I'm already spoken for!

F/n: Luci... can you please sit down so class can begin?

Lucifaina blushes at her cute nickname to her betrothed from a blood contract as she walks over to the empty seat behind him as she glares at his ex friend with her eyes glowing bright as a warning and when class dismissed both of them head to the Cafeteria

Lucifaina: So can I call something F/n?

F/n: Your choice Luci?

They stop when his ex friend gets infront of the duo with his gang and his ex girlfriend beside him dressed like a biker girl

F/n: Lucifuge... that my ex girlfriend and friend, Duncan and Stacy but those are his gang member the Blade of Samuel!

Duncan: Hey sweetheart... why don't you abandon the loser and be my side hoe?

Lucifaina: Tempting but no... your lacking something important for me!

Duncan: What that money, protection, fame?

Lucifaina: No a decent size cock for one... and two if you touch F/n, I'll destroy you!

She channels a bit of her demonic power to show a terrifying aura as she whistles and howls are heard

Stacy: What was that?

Lucifaina: My pets... they won't attack unless I command them!

F/n puts his right hand on Lucifaina head between her horns as she cheers up as she being treated with affection

Lucifaina: You been warned... touch him in anyway and your dead!

They walk past them as she whistles to call them off around them as she stops and pulls F/n close as she bites his neck as it looks like she giving him a hickey on the crook of his left neck before parting aways with him as she licks her lips exicited

Lucifaina: That mark... shows that your my property to other demons... and I can locate you if something arises, plus it part of the Blood Oath you performed... once a pact been formed the demon must bite his or her summoner to allow said demon to maintain in their plain till your death! But your Blood Oath much more powerful as you banged yourself a demon princess... that should be impossible to summon a upperclass demon like myself without a worthy sacrifice to give!

F/n: What else was in that contract?

Lucifaina: If we ever spilt apart if we revoke it... your soul is returned to you free of hell and I take half your belongs! As you preformed unknowing proposed to me in the summon... Oh and dad going to kill you!

Later

Lucifaina returned to Hell to gather a few things aswell inform his future in laws as he writes a note saying he'll be back after a few hours with the time he wrote it for her... F/n walking around the city till he stops to look at a brunt house as he just stands there as Lucifaina in Hell before her parents

Lucifaina: Mother... Father... to explain why I disappear, I was summoned using a blood oath and I marked him as my property!

Satan: A human summoned my... baby girl?

Lilith: How cute is he?

Lucifaina: He pretty cute mom... but the Blood Oath made us engaged.

Satan: He... he... dead!

Lilith: Dear she marked him... and he under her protection from any and all demons even her father! So your in school?

Lucifaina: Yes... I'm Lucifuge Morningstar on Earth... So daddy can I stay with F/n?

Satan: You can but if he so much as hurt you... I'll drag his beaten bloody body to the pit to torment myself!

Lilith: I wanna meet are human son in law!

Lucifaina: Of course mother... I'll go pack a few things I'll need! And father I'm half succubus... so if I want him I'll take him!

As Lucifaina packing up some clothes as packs her magical mirror to call her parents, a few personal items, and her trusted friend during heatwaves as she temping on using it always meanwhile F/n getting his ass beat by the Gang led by Stacy who sucking on a lollipop as she wearing a bra only under a fur jacket as her skirt very short revealing her shaved mound

Stacy: Wow your pathetic... your girlfriend talked all that shit earlier then abandons you what a little slut!

Stacy: Well I don't need a weak man... Duncan stronger than you and I have daddy around my pinkie!

F/n: But you don't have a Princess from Hell, do you?

Stacy: Hell can suck Duncan's cock and eat me!

Lucifaina appears from the darkness as she looks livid as her wings are large and her tail looks like a whip with daggers

Lucifaina: I smell a soul in need of punishment!

Stacy turns to see Lucifaina showing her demonic heritage as as she grabs Stacy by her throat and grips her painfully

Lucifaina: You can't run... Blades of Samuel, so won't escape your personal Hell Stacy!

In a flash she holding a cage with a naked Stacy and gangmembers that where beating my ass

Lucifaina: Honey... you ok?

Stacy: God save us please... I'll change I swear to you!

Lucifaina retrieves Stacy and grins with sharp teeth showing

Lucifaina: Call me Luci, love!

F/n: Goodnight!

Lucifaina glares at Stacy as she livid at her as she puts her in her vibrator as it seethrough

Lucifaina: Your suffering my wrath for him angry at me human!

Lucifaina inserts her toy into her pussy after she strips and turns it on low speed as she heads to bed as she cuddles with her fiance as she puts his head against her breasts as she admiring his nude form as she joins him in sleep as Stacy trapped in the princess's vibrator in her pussy as she hearing the screams of hell driving her mad

Next day

Lucifaina and F/n enter class as she smiles wickedly at Duncan as his girlfriend decent into madness powering her vibrator and he glares at her and when class over they head to get lunch but Duncan blocks them

Duncan: Where is Stacy?

Lucifaina: Not saying... I warn you!

Duncan: Fine... then I'll see you soon L/n! Lucifuge suck my cock!

Lucifaina: No cause not much of one... and my fiance better!

Duncan: He a loser with no family!

Lucifaina: Wrong my family is his family... and you'll have your whore later after I'm done breaking her mind!

They enter the Cafeteria as Duncan see a demon tail sliding back under her skirt as he shocked as he leaves the school to get his gang ready for a fight and when school over Lucifaina approaches Duncan's gang headquarters under the freeway with a smile on her face as she walks past the grunts looking like Stacy as she approaches Duncan

Duncan: Stacy... your ok? I sent them after F/n!

Duncan watches Stacy morph into Lucifaina as she wearing a dominatrix outfit as he bound to his chair by charred flesh hands as she approaches him

Lucifaina: Your boys won't be alive as I'm protecting him with a good friend of mine... but you want me to suck your cock well then suck mine!

Lucifaina persents her dildo as Duncan looks at the figure inside it as she shoves it in his mouth as he muffling out screams

Lucifaina: Never piss off the Princess of Hell... your girl broken by the screams of the damned! Enjoy my fluids as I curse you with erectile dysfunction and heart diseases.

She pulls out her vibrator and she gives him his girlfriend normal size as she scared of Lucifaina before she leaves but not before she snaps her fingers to start a fire as Duncan see her sinister smile as she licks her lips as she heads home as Stacy locked in an asylum and Duncan hospitalized for severe burns as his gang were found dead as Lucifaina acting like an angel as she sucking on a lolipop wearing just an apron as she cooking for her love

Lucifaina: Well no one touches my prince... and your with the daughter of Satan and Lilith... plus I might go reclaim my toy!

F/n: Luci... your trying to be a perfect girl but stop just be yourself the one who has my heart!

Lucifaina: Ofcourse dear... so can I go claim their souls cause I want to send them to hell!

Lucifaina feels her man remove her apron as she naked underneath as she feels him caressing her tail as she moaning as he touches the most sensitive part the tip as she disappears to get energy as she looms over Duncan as she shrinks him as she puts him in her mouth as she savors his charred scent of despair before appearing Stacy as she kisses her pushing her boyfriend into her mouth as she swallows in fear earning a grin from the demon

Lucifaina: You ate your strong Duncan... but your not free of my wrath!

Stacy shrinks again as she put into her mouth and positioned under her tongue before returning to her man as he looking at her wardrobe and she sits on the bed

F/n: Luci what did you just do?

She spit Stacy out and press her thighs together with a wicked giggle

Lucifaina: I want you to take my purity...

F/n sits beside her as he pulls her into a passionate kiss as Lucifaina blushing as her tail wraps around his waist before she reteives her soul food from her thighs as they part lips

F/n: I'll take your virginity in time my love... probably when I spend time in Hell for your birthday!

Lucifaina: My... birthday... sweetie your a human, you can't enter Hell?

F/n: Your dad will kill me wouldn't he?

Lucifaina: Yes so I'll enjoy my soul food!

Lucifaina puts Stacy in her mouth and swallows as Stacy sent into her stomach as she see the end of her life as she see her errors as she digesting Duncan as she digested instantly as she appears before above a lake of blood with Duncan and the gang as a older woman looking like Lucifaina holding a riding crop

Lilith: Welcome to Hell... My daughter busy having her senstive demon appendages touched as it so poggers!

They look at him shocked as Lilith astatic by that one

Duncan: You insane?

Lilith leaves as they're violented painfully by her pet as she watches her daughter bathing with her fiance in a bubble bath as she nuzzling up to him as she looks like a succubus who had the best orgasm ever with droopy eyes and heavy breathing

Lilith: Dear... did he touch her tail?

Lilith: Huh... seeing double are you?

Satan: Yes... and he brought her climax as the school collasped!

Lilith: Dear... I want the same treatment now!

She grabs his tail and drags his whipped ass to the bedroom as F/n one day woke up in Hell as Lucifaina sleeping beside him as he see a older version of her
