Serafall’s Fall (High School DxD)

Serafall’s Fall (High School DxD)

A/N: Serafall's Fall was a commissioned one shot originally written back in March of 2022. Posting it up here and now for people to enjoy!

Summary: Serafall is hearing rumors of a new human magician contracting with multiple female devils across the Underworld. So of course, she investigates.es: Hypnosis, Master/Slave, Rough Sex

-x-X-x-

Contrary to what some might think, Serafall Leviathan was not an idiot. Oh sure, she put on something of a show with her whole Magical Girl persona and what not. But at the heart of things, she was a Great Satan for a reason. More than that, she was in charge of Foreign Affairs for a reason as well. And sure, part of that reason was that the others were all waaaay less approachable, but at the same time, the other part of that reason was that Serafall knew her stuff!

Which was why she was a little surprised when it took so long for the rumors to start crossing her desk. As the Satan Leviathan in charge of the Underworld's Foreign Affairs, Serafall was usually privy to these things a little sooner! While they didn't keep track of EVERY human magician in the world above, they certainly tried to keep tabs on the ones capable of summoning Devils from the Underworld... and they CERTAINLY kept tabs on the ones who'd sold their souls to Devils as well!

It had become somewhat inaccurate, the old mythos that every Devil wanted a human's soul for whatever deal they wanted done. These days, it was a lot less dire when a transaction between a Devil and a human took place. More often than not, it was just a source of income... as in, literal money. Currency made the world go round after all, and not since the time of the previous Great Satans had the Underworld actually traded in literal souls as currency.

At the same time however, there were always exceptions that proved the rule. Most of the humans up top weren't valuable enough for the Devils down below to want their souls. In the end, the average human soul held barely any value at all and was practically worthless to the Devils powerful enough to even be able to claim such a thing via a deal in the first place.

But when you got into human magic and power, then things became a little... greyer and undefined. The line, so to speak, became a lot wider and a lot blurrier, that was for sure. Powerful Devils and Human Magicians seeking that power... name a more iconic duo.

The point was, most of the Pillars had Human Magicians in their 'employ'. Most of those Human Magicians were under contracts that effectively sold their souls to the Pillars they'd ended up dealing with. It was rare for Devil Society to leave a human who had proven capable of summoning them of his own power alone for long. When you started dabbling in that sort of thing, you were quickly snatched up.

But that, Serafall felt, was where the oddities regarding this particular case began. Because apparently, this latest magician had started summoning Devils of increasing power months ago and hadn't stopped or BEEN stopped. All female, curiously enough. But even curiouser... all of his summons were convinced that THEY owned his soul. Each and every one of them would tell her or her agents, if asked, that as a result of their dealings with this human magician, they personally had claim over his soul.

It was an odd smokescreen to be sure. No one was going after this new magician, because he was already 'claimed'. The problem was, he was 'claimed' by a dozen female Devils, all of them quite powerful. And when certain friends of hers, such as Grayfia Lucifuge and Venelana Gremory, claimed that they too owned this magician's soul, Serafall began to grow... concerned.

That was why she'd gone ahead and done something that, if found out, would likely get her in trouble. Not that she had superiors, she was her own boss and all that, but she had peers, and there would be pressure on them to put pressure on her, if it was found out that she was abusing her authority like this. Still, Serafall had to get to the bottom of this. And so, she'd... tweaked things a bit, in her capacity as the head of Foreign Affairs.

She'd made it so that this human magician's next summoning... would pick her first, above all others. And as she feels the summoning take hold, a smug little smirk spreads across Serafall's face, as she prepares to face off with this mysterious human entity and get to the bottom of things.

Feeling the insistent tugging of the magically enforced summoning, Serafall lets it take her, finding herself forcibly drawn from the Underworld all the way up to Earth. This was the difference between your average human being given a specific summoning contract by their local devil in order to make some deals so the devil can earn some petty cash, and a full-fledged human magician who could pull a devil straight from the Underworld itself.

Of course, Serafall likes to think not even the strongest human magician would try to summon a Great Satan. She can't help the way her smirk grows, as she appears in the summoning circle and takes in the surprised expression on the young summoner's face. Hm, and he is YOUNG. She can tell, he's not some old geezer using magic to make himself appear younger, he's actually almost a child, barely past maturity by human standards.

She's a little surprised herself, because his name... well, his name made him sound old. Or maybe that was just her bias against anything biblical, speaking?

"Hm, are you Ezekiel?"

Ezekiel eyes widen and he jolts as he quickly stands up, staring at her with Mage's Sight, a relatively common human magician spell. Serafall knows how she likely looks under it... the most powerful Devil he's ever summoned, though ladies like Grayfia and Venelana are certainly close seconds and thirds. Maybe that's why the young human recovers so quickly.

"A-Ah, ahem... yes, I am he. And... who might you be, Devil?"

She ponders going full Magical Girl mode for a second, just to seriously fuck with him... but no, Serafall decides she needs to take this seriously if she's going to get to the bottom of this. She can always go visit her little sister and embarrass So-tan in front of her friends by falling into the persona of Satan Pink later on. As it is right now, she needs to be the Satan Leviathan.

"I am Serafall Leviathan, Great Satan of the Underworld... in charge of Foreign Affairs. And you, young man, have been making a bit of a mess of things. Care to tell me how you sold your soul to a dozen Devils without them all tearing you apart for your hubris?"

Ezekiel's eyes have gotten progressively wider as she speaks, and he takes another step back. Seeing the open door to the ritual chamber behind him, Serafall flexes a bit of her Will, and it slams shut in quite the satisfying manner, making him jump.

"A-Ah, u-um... a-aren't such contracts confidential?"

"No."

Her succinct answer makes him pause... and then the young human's shoulders slump. It's almost pitiable, Serafall can't help thinking, as he pulls a pocket watch out of his robes.

"I used this to make deals with them. All they had to do was look at it very intently, and my soul was theirs. All of them agreed, I swear!"

As he speaks, he unfurls the pocket watch on its chain and begins swinging it. Serafall's eyes narrow as she stares at the device, trying to suss out its secrets. Obviously, he was lying, but it was such a ridiculous lie that she actually couldn't immediately suss out the truth of it. What the hell was going on here, exactly? How did staring at a pocket watch equate to a human's soul, and how had Ezekiel somehow sold his soul to a dozen female Devils this way without them all getting jealous?

It didn't make sense, and after a moment Serafall tears her gaze away from the oddly hypnotic pocket watch and narrows her eyes at Ezekiel.

"That's a stupid deal. Why would anyone agree to that? And it still doesn't explain how you sold your soul multiple times, human!"

Ezekiel flushes and tucks the pocket watch away, before spreading his hands in a somewhat helpless gesture and hesitantly smiling.

"Ah, well... I should have known the Great Satan Leviathan would see right through my tricks and lies. Perhaps... perhaps the two of us can make another deal? A wager, if you will!"

Serafall frowns but cocks her head to the side.

"... I'm listening."

Beaming, Ezekiel explains.

"It's simple, really! You take off all your clothes, get down on your knees, and suck my cock to the BEST of your ability! If you make me cum, then I win and get to fuck you silly for the rest of the night! If you don't, then I'll answer all your questions truthfully and submit to your judgement!"

"You're a foolish young man, aren't you? To so cavalierly bet your own soul on something like this! You could have at least traded it for something instead, but now you're going to lose it to me for nothing! Don't worry though, I'm a kind mistress, you'll see~"

Ezekiel just smiles wanly and nods along with her, his cock already rock hard again, and twitching in anticipation of fucking the Great Satan. Her words are amusing, but it's hard to focus on her silly, ridiculous twisted perspective when he only has eyes for her smoking hot body.

Smirking as if she's somehow already won, when it is in fact impossible for her to win their little lopsided deal, Serafall turns and saunters over to the nearby wall. Planting her hands on it, she bends over and thrusts out her ass, before reaching back with one of those hands to pull one leg up into the air and reveal her naked, glistening wet pussy lips.

"Well? Come on! Come and fuck me already so I can claim your soul when you completely fail to cum inside of my tight, wet pussy!"

... Really, how could he refuse an invitation like that? Stepping forward, Ezekiel places his hands on Serafall Leviathan's ass, marveling in how soft and firm her butt cheeks are at the same time. She clearly works out... on top of being the most powerful female devil in existence, more than likely. But she's also totally a woman, with a woman's softness.

Groaning in appreciation even before he thrusts into her, Ezekiel kneads Serafall's ass for a few moments longer, before finally lining up his cock and shoving his way in. Serafall grunts, and her pussy walls clench and squeeze down around his shaft. He almost cums right then and there, and while it WOULD be his 'win', Ezekiel... Ezekiel holds off.

He wants to savor this moment. He wants to take it in and soak it up for as long as possible. This was for his grandfather, but more than that, this was for all of humanity. As he begins to thrust into Serafall Leviathan from behind, pounding the naked horny devil as hard as he can, uncharitable thoughts flicker through his head.

Fuck Devils for taking advantage of humanity for so damn long!

Fuck them for stealing the best and most magical of humanity and making them into slaves!

Fuck them for trying to hold humanity back, for trying to contain them like sheep in a big fucking pen!

Sure, humanity had ascended via technology all the same! Sure, the species had been fruitful and multiplied, utilizing humanity's strengths in order to cover for its weaknesses! Ezekiel was proud to be human. He was prouder even still to be his grandfather's grandson, and to have this chance to stick it to the devils who had wronged them for so damn long.

As he fucks Serafall, she begins to moan and groan and shift her hips back into his cock subconsciously. He hadn't said she had to try her best this time around, trusting that her hot wet pussy would be more than enough to make him cum whenever he wanted. And yet... Serafall is beginning to join in on the fun all the same, bouncing her big bubble butt backwards as he thrusts into her gushing quim from behind.

Fuck, were all Devils this slutty? Licking his lips, Ezekiel eyes the Great Satan's hair. The twin pigtails she's sporting have had his attention since he first summoned her, to be perfectly honest. And... why not, right? In for a penny, in for a pound!

Reaching forward, the young human grabs the Satan Leviathan's pigtails and yanks them back, causing her to cry out and her back to arch as he uses them like reins and begins to fuck her even harder. Serafall squeals as his cock squelches in and out of her cunt. She shudders, as her pussy walls flex around his dick. And Ezekiel grins, chuckling throatily as he gets closer and closer to the point of no return, where no amount of trying to hold back the rising tide will be enough.

"I'm getting close, o' Great Satan! If I cum, your soul is mine!"

"What?! How can you already be about to cum?! That's not possible!"

"Here it goes!"

"Noooooo~"

Patently ridiculous twisted perspective aside, it's hands down one of the best releases of Ezekiel's young life. But then to be fair, it's the first that results in him having direct ownership of a Devil's Soul. He can feel it, as he cums deep inside of her. The Devils rely on their contract magic for everything. It is the foundation of their entire society. His grandfather's pocket watch undermines the entire system by its very existence, but more than that... it offers a way to insert himself into that system.

Serafall's soul fills him with power. A human magician, with the full might of a devil's magic to call upon. And not just any devil, but the Leviathan's herself. A shuddering breath leaves Ezekiel, as he finishes creampieing his new slave from behind. A shiver runs down his spine, as the ramifications of what he's done hit him.

Slowly pulling out, he watches Serafall slowly slide down the wall, whimpering as his cum gushes from her pussy. She's so much more powerful than him, it's not even funny. Or rather, she was. With her soul at his beck and call, he can do so much more now. He can live forever, for one... or as long as she does anyways. Not that he's going to rely on a single point of favor.

Now that he's claimed Serafall's soul... it's time to do the same with the rest of his thralls. But first...

"I own you now, bitch."

"... Y-Yes, Master..."

"Come on then. And don't walk in my presence, ever. Crawl."

"Yes... Master..."

And so, a downtrodden, defeated, hypnotized Serafall crawls after him, following him out of the ritual chamber, up the stairs into his house. He's got leftovers in the fridge, and he quickly heats them up before heading to his computer room. He might be a magician, but he's also a young man in the twenty-first century, heh.

As he settles into his computer chair, his dick still out, Ezekiel points under the desk.

"Go there. Clean my cock. And then suck it until I say stop."

And the Leviathan... obeys. He knew he wouldn't be able to keep her here forever. He couldn't afford for her male counterparts to notice anything was wrong. Not until he'd bound... at least another dozen powerful female devil's souls to his own. Then, he would be stronger than all of the male devils in the underworld by several factors. Then, he could overtly take over the entire fucking place, if he cared enough to.

But for now, he eats his dinner and browses reddit, while enjoying the triumph coursing through his veins and the sensation of a Great Satan under his desk, blowing his cock.
