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."
