Y/N: YOU FUCKING DID WHAT?!

Blitzø flinches a little and covers his ears.

Blitzø: Oh don't get your panties in a bunch. I just made a deal with a Goetia that you'll be his sex toy and we can use his book.

Y/N pinches the bridge of his nose and takes a seat. From his time in Hell, he's learned about their caste system and how things work:
(Fair warning, I'll be changing the caste system a little bit)

Imps and Hellhounds: The lowest of the low in Hell's society. Hellhounds and Imps are commonly used as cheap labor.

Sinners: Essentially the bulk of Hell's population but also the average class. A Sinner is a Demon who was once human but died and went to Hell because of their Sins.

Hellborn: Demons who, as the name suggests, are born in Hell. Hellborn are above-average citizens, middle class essentially.

Overlords: Influential Demons with powers that seem unimaginable to other Demons. Overlords rule over something in Hell, specifically their respective ring, and are both famous and infamous for doing so.

Ars Goetia: The Highborn in Hell's Society. The Goetia are messengers and observers for Lucifer with access to the human world and a specific plan set for their entire family.

Seven Deadly Sins: The head honchos of a single ring of Hell. They report directly to Lucifer himself.

Royal Family: The bigshots and rulers of Hell, nuff said.

Y/N: How in the ever-loving FUCK do you even have contact with someone like that?

Blitzø: Long story, really long and boring, I'll have to tell you sometime. Anyway, let's get going to Stolas's big ass mansion.

Y/N: I am not a gigolo-

Blitzø: I'll triple your pay-

Y/N: -for a cheap ass price. Let's go!

Timeskip
The IMP van pulled up to Stolas's mansion, hitting any poor Imps who happened to be in the way. The gigolo of the evening looks at the mansion with an impressed whistle.

Y/N: Damn. I knew the Goetia Demons are considered elites in Hell but this is impressive

Blitzø: You bet your sweet ass it is. Now go in there and make Daddy some money!

Y/N: Guess I'm gonna be the bottom bitch.

Y/N gets out of the van, prompting Blitzø to pull off before he could even close the door. Sighing a bit, he walks up the elaborate stone path to the door. Before he could knock, the door slowly opened on its own.

Y/N: Not creepy at all...

Y/N walks through the elaborate halls, guided by a VERY alluring smell. The smell brings him to a room, where he barges in without knocking. Both his Hellhound and Incubus instincts went into overdrive at the scent, so reason went out of the window. The sight almost made him pounce right then and there.

Stolas: My my~, someone's impatient~.

Stolas giggled at Y/N's shell-shocked look. The air in Stolas's mansion was thick with tension as Y/N entered the room. Stolas, the proud and powerful owl demon, sat on his bed, his piercing gaze never leaving Y/N's muscular form. Long black hair, fading into a vibrant orange at the tips, cascaded over Y/N's broad shoulders, framing a strong jawline and full lips that practically begged to be kissed.

Stolas: I take it Blitzy informed you of your duties?

Y/N: Yeah....he did...

Stolas: Well then, let us dally no longer~

With a sensual giggle, Stolas unwraps his robe rather swiftly and throws it onto Y/N. Surprised, the male takes Stolas's discarded clothing off of him only to be met with an even BETTER surprise....

Stolas: Blitzy has informed me of your little fetishes. I do hope my posterior is to your liking~.

Y/N approached Stolas slowly, his eyes never leaving the sight of Stolas' ass. He reached out to touch it, his fingers trailing over the soft flesh as Stolas moaned softly. The demon male's touch sent shivers down Stolas' spine, and he couldn't help but arch his back in response. 

Stolas admired Y/N's features over his shoulder, his smile still ever-present. Y/N, a hellhound-incubus hybrid, was infamous in Hell for his stunning looks and insatiable appetite for pleasure. Even before this deal, Stolas had heard rumors about him, how he could make even the most stoic of Demons squirm with pleasure. Y/N's long black hair, fading into a warm orange hue, fell in loose waves around his broad shoulders. His deep, dark eyes were filled with a mischievous gleam as he looked at Stolas, taking in his slender frame and bird-like features. Stolas knew that Y/N could see the hunger in his eyes, and it only made his heart beat faster. 

Y/N: Lay on your back, now.

With a giggle, Stolas lay spread-eagled on the bed, his plump, feminine curves on full display. His long, slender legs were spread wide, his hands resting on his stomach as he gazed up at the towering figure before him. The Demon male was a sight to behold - his muscular frame rippling beneath his skin as he moved with a predatory grace. His skin was a deep, mahogany hue, and his hair was a wild tangle of black and orange that framed his chiseled features. He was a hellhound-incubus hybrid, and Stolas had never seen anything quite like him before.

Y/N traced his hands down Stolas' body. His eyes were closed as he savored the sensation of Y/N's fingers trailing over his sensitive nipples. He moaned softly, his hips moving in time with Y/N's touch. Y/N leaned down to kiss Stolas' neck, sending shivers down his spine.

Y/N: You know the deal, Stolas. This for the book.

Y/N growled, only serving to turn Stolas on even more. Stolas opened his eyes, meeting Y/N's predatory gaze.

Stolas: I know...but I want you to enjoy it as much as I do.

Y/N: I already am, Stolas. You're a delicious little bottom. 

Stolas blushed before smiling, his eyes half-lidded.

Stolas: Let me show you just how much of a willing submissive I am.

Y/N grinned as Stolas sank to his knees before him, his lips parting as he took Y/N's length into his mouth. Stolas moaned softly as Y/N's hands tangled in his hair, guiding him as he moved deeper and deeper into Stolas' throat. Stolas could feel Y/N's desire building within him as he continued to suck and lick at Y/N's length, his own body heating up in response. Stolas was relishing in the salty taste and the way Y/N's body shuddered with pleasure. As he looked up at Y/N through his long lashes, Stolas could see the lust and desire burning in his dark eyes.

Y/N: Damn your good at this...

Hearing the praise, Stolas gets even more determined to milk Y/N with his throat. But Y/N wasn't satisfied with just a blowjob. He wanted to taste Stolas too. Y/N picked up Stolas, much to his chagrin, and threw him onto the soft bed. Before Stolas could question it, Y/N's tongue darted out to taste him, sending waves of pleasure through him that left him gasping for breath. As Y/N continued to explore Stolas' body with his tongue, Stolas reached out to touch Y/N's hair, running his fingers through the wild tangle of black and orange that framed Y/N's chiseled features. Y/N growled softly in response, his eyes never leaving the sight of Stolas' ass. With a flick of his tongue, he had Stolas begging for more, his hips grinding against Y/N's face as the hellhound-incubus hybrid devoured him. And just when Stolas thought he couldn't take any more, Y/N moved his attention lower, his lips and tongue teasing Stolas' tight entrance. Y/N stops, only to tease Stolas.

Y/N: Damn your a fucking slut.

Stolas blushed, but he couldn't help but feel a thrill of excitement at Y/N's words. He knew that Y/N was a dominant top, and he loved the way that Y/N made him feel - vulnerable and powerful all at once. Though Blitzø informed him of Y/N's personality and he paid attention to the rumors, seeing truly is believing.

Stolas: S-such skill~.

Y/N finally pulled away from Stolas' body, his eyes never leaving the sight of Stolas' ass or winking hole once more.

Y/N: Turn over, It's time for your punishment.

Stolas blushed as he turned over onto all fours, feeling a thrill of excitement mixed with fear as he heard the sound of chains being unhooked from the wall behind him. He knew what was coming next - BDSM at its finest. And what followed was a blur of pleasure and pain. Y/N expertly used the various equipment, bringing Stolas to the brink of pleasure and then pulling back, leaving him hanging, begging for release. But Y/N never stopped, never gave in, pushing Stolas to his limits and beyond.

Y/N approached him slowly, his eyes never leaving the sight of Stolas' plump ass once more. He reached out to touch it, running his fingers over the smooth flesh before him. Stolas moaned softly as Y/N began to spank him - hard and fast - sending waves of pleasure through him that left him gasping for breath once more. As Y/N continued to spank him with a fierce intensity that left him breathless, Stolas couldn't help but feel grateful for this moment - this moment where he could be nothing more than a submissive bottom for this dominant top who had taken him so completely into himself once again. It was a feeling unlike any other - one that left him feeling both vulnerable and powerful at once once more. And as they lay there together in this moment of pure bliss once again, Stolas knew that he would never forget this feeling - this feeling of being completely consumed by another being in every possible way once again.

Stolas: More daddy~! Punish this regal owl more~!

With a smirk, Y/N employed just about every tool Stolas had in his arsenal:

Spankings with a paddle...

Dripping candle wax...

Vibrators on the balls...

Small weights clamped to his nipples...

Gagged and blindfolded...

Earmuffs...

Nothing was out of range for Y/N's perversion or desire. And when Stolas thought he couldn't take any more, Y/N flipped him over and entered him from behind, his strong hands gripping Stolas' hips as he thrust into him with an almost primal force. Stolas cried out in ecstasy as Y/N pounded into him, his fat ass bouncing with each thrust. Stolas could feel every inch of the demon male's length filling him up, and he couldn't help but moan again as Y/N began to move within him with a frenzied intensity that left him gasping for breath.

Every thrush carved out more space for Y/N's dick, shaping Stolas' walls into its shape. Stolas gave muffled moans as Y/N's girthy length punched his prostate, causing him to cum torrents of his white liquid. Every slap to Stolas's fat ass only makes his walls clamp around Y/N's cock, something the sexual Hellhound enjoyed VERY much. Y/N suddenly pulled out of the pleasure-stricken owl, leaving him on the verge of a climax.

...

Y/N lifted Stolas up onto his knees once more and guided him forward until he was straddling Y/N's cock once more - but this time, it was different - this time, Stolas was riding Y/N in reverse cowgirl - completely consumed by the darkness and the silence that surrounded him once more. Stolas could feel Y/N's hands on his hips as he moved up and down on Y/N's cock once more as he rode the dominant male. He could feel every inch of Y/N's length filling him up, driving him wild with desire once more - completely consumed by the darkness and the silence that surrounded him once more.

Stolas could do nothing as Y/N treated his body as nothing but a cheap toy. Every thrust, every slap, every grunt was more of a reminder of Stolas's place: under Y/N both figuratively and literally. Next thing Stolas knew, he was being lifted and restrained by his own legs as Y/N jackhammered his insides in a Full Nelson. Though his moans were muffled, it didn't stop the Imp servants from seeing and even secretly playing with themselves. Stolas was on cloud nine. His own wife and not even his darling Blitzy could make him feel like this. Even when Blitzø snuck into his mansion during a party, the feeling doesn't compare.

Y/N released the Full Nelson hold and guided Stolas into a missionary position as he removed the blindfold and gag from Stolas' face. Stolas could see the hunger in Y/N's eyes as he moved within Stolas once more - both Y/N's wolf-like grunts and Stolas' owl-like hoots echoing throughout the room. Y/N leaned down to kiss Stolas deeply, their bodies moving in time with each other as they explored the depths of their desire for one another. The demon male continued to move within Stolas with a fierce intensity that left him breathless. He could feel every inch of the demon male's length filling him up, and he couldn't help but moan again as the demon male began to move within him with a frenzied intensity that left him gasping for breath.

Y/N can feel his end nearing, causing him to bite Stolas' collarbone. The sudden action made the Noble Demon hoot and moan in pain and pleasure as he came more. Eventually, Y/N finally cums in Stolas after a series of powerful thrusts. The wolf gave a muffled "FUCK" as Stolas cried out in ecstasy, his legs shooting into the air. They lay together, their bodies tangled and sweaty, basking in the afterglow of their steamy encounter. Stolas had never felt more satisfied and content. As they caught their breath, the demon chuckled and pulled out, his dick being the plug that kept the cum in Stolas' abused hole.

Y/N: Best believe I'll be back, that ass is MINE now.

Y/N used one of the unFortunate Imp maids to clean his dick as she got caught masturbating. After putting on his clothes and slapping a few asses, he finally left the mansion, but not before taking a few pictures of the used Stolas.

Sorry if this Lemon wasn't worth the wait. I wanted it to be 4,000 words but I am TERRIBLE at writing sex scenes
