Vaughn and Malivia are members of a race of monsters known as the Lilin, sex demons who feast on the life force of humans through sexual intercourse in order to survive. Male Lilin are called "incubi" while female Lilin are called "succubi." Incubi are much bigger and stronger than succubi because of their near insatiable appetites forcing them to devour any human they come across regardless of sex. Succubi however are more picky and selective with their victims, making them smaller and slightly less powerful than their male counterparts.
Vaughn: Vaughn is what is known as a Greater Incubus; a Lilin with a high Mana aptitude. Lilin like Vaughn are uncommon, but exist, making him a very powerful demon. Draped in leather, chains, and zippers with piercings on ears, ass, and genitals, Vaughn's provocative attire compliments his long raven black hair, ebony wings, and ashened lips. He is 9 feet tall, over 350lbs, and loves Malivia dearly.
Malivia: Malivia is what is known as a Lesser Succubus; a Lilin with a low Mana aptitude. Lilin like Malivia are extremely common, especially if they are half-breeds which Malivia actually is. She must take Mana from a Greater Lilin if she wants to become a full-fledged succubus, and was chosen by Vaughn to become his thrall because of her potential. Wearing nothing more than a leather strap for a bra and a spandex thong for panties, Malivia's bronze skin and voluptuous physique compliments her outfit beautifully. She is 5'3, 120lbs with H-Cup breasts and 40 inch hips. She too loves Vaughn but is unable to express her feelings because of her status.

It was uncommon for a lilin of Vaughn's status to take a little thing like Malivia under both his literal and metaphorical wing. Training for lower lilin were generally overseen by high-rank demons with just enough Mana to spare for creatures like Malivia, not noble-ranked aristocracy with near-limitless Mana reserves like Vaughn. Malivia was honored that a demon of Vaughn's status would even look her in the eye, let alone become her Master, so when Vaughn claimed Malivia as his pupil, Malivia immediately dedicated herself to becoming Vaughn's dutiful servant. The Upper Houses that Vaughn belonged to were shocked that one of their own would do such revolting "grunt" work like educating a lesser demon, but Vaughn didn't care and knew that he himself was too powerful to be felled by enraged noblemen for his actions anyway. Malivia would apologize to Vaughn profusely whenever she was brought up in an argument between Vaughn and his peers, but the older demon would merely smile and ruffle Malivia's silver locks to calm her down. When that didn't work, and Malivia couldn't get over the shame that came with being a lesser demon, Vaughn would hold Malivia up to his height, pin her against the wall, and peer into her crimson red depths as he smirked shamelessly at her. A proposition carried by a sweet lilt of playfulness would then fall from Vaughn's lips when he did this, a promise of magical exchange that made Malivia not only feel better but made her forget about what was worrying her in the first place. Thighs clenching, tail flicking, and wings fluttering, Malivia would fall victim to Vaughn's charms and give herself up to him in hopes of deepening their bond.
Vaughn would carry Malivia into his quarters and ignore the pensive glares and judgemental eyes that bored holes into Vaughn's back as he passionately tongued his thrall's mouth. So much bigger than her in every which way, Vaughn's kisses were suffocating, and yet incredible. His tongue filled her mouth completely, flesh slipping into every crevice and gap that was past her lips as he slowly guided his tongue down her throat while his black lips covered her own. Malivia had no space for her own little tongue to move and was happy with just sucking on Vaughn's, throat swallowing around the wetness that entered her shuddering gullet as Vaughn kicked the door to his chambers open. He purposefully left it open in hopes that stuck-up nobles would see him ravish and nurture his student with his mana. It made a statement, and although embarrassed by the lingering gazes of servants and repugnant stares of royals, Malivia couldn't care less who looked when Vaughn got her into the bed.
As she was too focused on servicing his tongue, Malivia let Vaughn make quick work of her clothes, gasping as his giant fingers uncinchined buckles, belts, and buttons that kept her voluptuous figure from his view. First it was her breasts that he'd free, two heaving mounds of flesh that hung provocatively from Malivia's chest and spilled from her hands with ease when Malivia was made to hold them for him, and as he drank in the sight of her brown tits, he'd then pull off her leather thong to reveal a hairless ebony cunt on full display that gushed heavily with rich juice. Vaughn could literally spend hours drinking up her quim when he had the time and leave Malivia a panting, drooling mess, but the young succubus hoped that he wouldn't spend half the night tasting her like he did the last few times they did this. It was Malivia's hopes that she'd be able to take Mana from Vaughn properly, and in an attempt to voice her concerns, forced herself to spit out Vaughn's tongue and regarded him with plaintive, misty eyes.
"My Master," She began. "Please let me be the one to attend to you tonight."
Vaughn sat up to observe Malivia's flushed face, his lips curling into a devilish smirk as hunger and mirth danced in his eyes. He licked along Malivia's flushed skin with his long, serpentine tongue before whispering teasing words into her ear.
"My little deviant," Vaughn tittered as he rose higher off the bed. "You wish to feed upon me this time, darling?"
Malivia nodded eagerly, mouth already starting to water.
"Very well," Vaughn began to undress and adjust himself accordingly. "You may stop when I am satisfied then."
Malivia watched Vaughn peel off the leather and chains that barely covered his massive pecs before removing the giant codpiece that kept his organ hidden, the younger lilin biting her lip when she saw Vaughn's cock bounce and sway into view; that giant trunk of flesh he called a shaft throbbing with life as thick bulging veins pulsed with his heartbeat. Impressive as it was intimidating, Vaughn's cock was a solidly thick piece of meat that spanned the length of his entire arm with a circumference so great even he could barely keep his entire fist around it. Even his cockhead was massive, a darkened tip of swollen nerves that dribbled enough pre-ejaculate to fill an entire goblet, but perhaps the most enticing part of Vaughn's loins that made Malivia's head swim, her inhibitions wane, and her self-control vanish were the hanging jewels that undulated rhythmically beneath his crotch.
As Vaughn shifted and turned in place to present his fat, muscled rear end to her, Malivia saw the sack of swollen flesh in all their life-bearing glory.
Vaughn's giant testicles were proportionate to his giant cock. Like over ripened fruit bursting with juice, his balls and the semen that churned inside of them was where Vaughn's Mana was most potent and Malivia enjoyed playing with his titan-sized sack as much as Vaughn enjoyed playing with her tight young cunt. She could slobber all over his nuts for hours, smothering herself in the smoothness of his skin and inhale his musk as she fingered herself to completion, and Vaughn himself found great pleasure in Malivia's unorthodox approach to foreplay. His balls had a tendency to swell and grow red with need the longer he went without plunging a hole, so having Malivia soothe his ache with her excited tongue alleviated the pain as it were.
Malivia laid down while Vaughn adjusted himself accordingly for his thrall, the incubus making sure his entire package hung over the younger lilin's face and his swollen asshole was spread out for Malivia's awaiting tongue. A giant, pierced hole about the size of Malivia's own mouth winked and clenched her way as suffocating heat radiated from Vaughn's rear, fond memories of Malivia making out with that perfect ass flooding her fogging mind. Malivia was never too sure which part of Vaughn she wanted to play with first whenever she was beneath him like this, but as the heat in her core intensified and her thirst for Mana overwhelmed her, Malivia groped Vaughn's hanging sack in both hands and kneaded his balls together before flicking at the hot piece of metal that was pierced through the wrinkled skin of his asshole.
Vaughn simpered at Malivia's choice and encouraged his pet to play more by slowly lowering himself on her face, careful not to crush her head with his weight as he completely smothered Malivia's face with his fat rear. She moaned pathetically at the hot, fleshy weight that was Vaughn's supple buttocks crushing her head, and sucked mindlessly at Vaughn's hole. Her lips barely cover the shuddering expanse of Vaughn's anus, but Malivia mouths and suckles upon his skin in a frenzy before pushing her lips and tongue into his hole to eat him out properly. She works her tongue in as deep as it can go, allows it to slither and snake up along rippling, velvety walls so it can reach Vaughn's prostate, and when she finds it, Malivia laps at it incessantly to coax the Mana that lurks there to come out and cover her long tongue.
Vaughn throws his head back and groans then, giant ass bouncing as he rocks himself against Malivia's talented mouth while his hand wraps around his neglected cock to jerk himself up. He strokes his length at a languid pace, forcing a stream of endless precome to leak out of his piss slit in a splatter that he uses as lubricant for his heated skin.
"Such an eager little whore, my dear." Vaughn purred. "Eating me up like a starved brat... It amuses me that you enjoy this part of me so much."
