Fertility Spell (High School DxD)
Commission
Thes: Rough Sex, Breeding, Marathon Sex
Summary: Serafall Leviathan accepts a summons to Earth one day out of sheer boredom. To her surprise, the magician who summons her actually has a pretty decent offer for her~
-x-X-x-
"Boooored… so boooored…"
In the privacy of her own office, Serafall Leviathan lants the tedium of her duties as the Satan in charge of Foreign Affairs for the Underworld. There was just so… much… paperwork. All she wanted to do right now was go out and have so fun! Or maybe go and film another episode of her Magical Girl Show!
But no, she was stuck here… ugh. She would do ANYTHING if it got her out of paperwork at this point and-
Serafall's eyes widen as she feels the telltale attempt of soone trying to summon her. It's as though soone heard her prayers and is answering them! Sure, normally she'd just ignore it, but she's just so bored right now that she might as well see what they want. And if nothing else, she'll be able to ss with them a bit before having to go back to work!
With a grin, Serafall allows the summoning to whisk her away from her office, following the thread and arriving on Earth re monts later. Of course, she arrives in her usual bombastic Magical Girl fashion, making sure there's plenty of sparkles and shimrs as she finds herself facing a young male magician.
"Magical Girl Levia-tan is here to answer the call, teehee~"
The magician stares at her nonplussed for a mont before clearing his throat.
"Serafall Leviathan. I wish to form a Pact with you."
Ugh, he was no fun. Not even playing along a little bit, already invoking the proper words and what not. Pouting briefly, Serafall smirks smugly after a mont and rolls her eyes in response.
"Yeah kid, there's a lot of magicians out there who would love to form a Pact with the great Levia-tan. So what makes you so special, huh?"
His jaw sets and his eyes blaze. He clearly has a bit of an inferiority complex and doesn't like being called kid.
"First of all, I'm not a kid."
Yep, there it was.
"My na is Aaron… and I've created a spell that will solve your race's fertility problems for good."
Wait, what? Serafall narrows her eyes as she stares down the young man. By human standards he definitely isn't a kid… but she's been around for a long, long ti. As a result, she has a pretty good idea when soone is bullshitting or bluffing her and this guy… isn't doing either of those things. He actually believes it. Of course, that doesn't an much.
Scoffing, Serafall offers a bratty shrug and a shake of her head.
"Yeah? I've heard that before too, just so you know. Most of the ti it's a scam."
"This ti it isn't."
Heh, his confidence is pretty unshakeable.
"I'll prove it to you if you want… right here and now."
Oh? Now he was starting to get a little interesting. Not to ntion, Serafall's own pride won't let her back down from such an obvious challenge. Giggling, she twirls her Magical Girl Wand for a mont before letting her eyes flash as she nods to the magician.
"Very well, Aaron. Show what you think you've stumbled upon."
Holding his head high, Aaron raises his hands and casts his spell on her. Technically, Serafall shouldn't have let just anyone cast any magic they wanted on her… but given who she was, she wasn't that worried. Only… almost imdiately she feels a pleasurable heat well up inside of her centered on her womb. More than that, Serafall's eyes widen a fraction of an inch as she feels her ovaries suddenly drop an egg.
A gasp leaves the Satan's lips and her thighs clench together as her pussy gushes fluids and her nipples beco hard as steel. This reveals the lack of a bra as they poke through the top of her uniform. Fortunately, centuries of experience allow her to keep a relatively straight and altogether smug face, even as she glares at the magician.
"Well? You said you'd prove it. What are you waiting for?"
To his credit, Aaron only hesitates for a mont before stepping forward. Only upon his approach does Serafall realize just how much taller than her he is, her heart pounding in her head as her pussy tightens around nothing at all. With a grunt, the magician grabs her by her ass and hefts her up into the air, proving that he's not at all a physical lightweight.
Serafall giggles as he smashes his lips into her own, her limbs clinging to his body while his growing bulge rubs up against her sopping wet pussy. Which is obviously bare since she's not wearing panties either.
When the kiss finally ends a while later, Serafall pouts and bats her eyelashes brattily.
"Hmph. You just stole my first kiss. I was saving it for my sister, so you better be sure to knock up or I'll be very, very angry~"
Aaron blinks owlishly at that perverse reveal, but in the end he gets this determined look on his face all the sa. Nodding sharply, he tosses Serafall onto a nearby bed, quickly shedding his own clothes and climbing on after her. Serafall doesn't make it easy for him though, distracting him while he disrobes by squirming and lifting up her top to expose her big, round, perfectly jiggling tits.
There's a smug smile on her face as Aaron's eyes imdiately lock onto her chest and then stay locked on. That smile remains even when he grabs her ankles and proceeds to fold Serafall in half right then and there. His cock is rather large, admittedly… and as it slams into her pussy, Serafall cries out, losing her centuries old virginity right then and there.
She wasn't like Sirzechs and Grayfia who had shacked up together after the war. She was waiting for the right person. For the longest ti, she'd actually thought that was her precious Sona. But now Serafall finds herself questioning such things because the one thing Sona didn't have… was a big, fat cock like Aaron~
As Aaron thrusts into her, he reaches around her legs to grasp at her plump breasts, squeezing them and rubbing them and tweaking her nipples as his cock soon finds itself assaulting her cervix. He's pounding against the entrance of her womb directly in no ti!
Plap! Plap! Plap!
Combined with the effects of the hyper-fertility spell that the human magician had apparently developed and the fact that she'd just lost her virginity to him, one might expect Serafall to go all ahegao, her eyes rolling back in her head, her tongue lolling out of her mouth, squeals falling from her lips.
… That doesn't happen. She's not the fucking Leviathan for nothing, after all! And while it DOES feel good… Magical Girl Levia-tan isn't going to fall that easily, if at all! With a wicked smirk from under Aaron, Serafall uses her flexibility and so acrobatics to maneuver her legs out from his hold in order to be able to wrap around his waist.
With his hands completely latched onto her breasts and refusing to let go any ti soon, Aaron doesn't try to stop her. Though he does grunt in surprise when Serafall uses her new hold on him to begin forcing him to batter her cervix much harder.
Thanks to her hellish strength, she's able to make him pick up the pace a lot more, even as she grins up at him and laughs.
"Harder, Aaron! Fuck harder~"
Aaron narrows his eyes, both of them knowing that in reality, Serafall is the one fucking herself harder using his cock. Still, he tries his best to give as good as he gets. Until finally, his throbbing mast punctures through her cervix, punching right on into her womb and smashing the 'gates' of her innermost castle' wide open in the process.
PLAP! PLAP! PLAP!
Serafall groans happily, cumming on the spot from what would have been a brutal and painful experience for any human woman. But she's not human, she's a devil. They're made of sturdier stuff… and have a built in love for so pain on top of that.
Of course, just because she's a latent masochist like most of her kind doesn't an she's just going to surrender without a fight… or even surrender WITH a fight for that matter. Aaron might not be willing to submit either, but Serafall knows if she wanted to that she could easily and utterly dominate him. The young human is entirely outmatched.
However… that wouldn't be very fun, would it? If she just took charge and wrung him dry, she'd get what she wanted in the end, but he would be destroyed both physically and ntally. And one thing was certain by this point… the spell that Aaron had created had real potential and extre implications on the future of devilkind.
No, Aaron was not a resource to be used up and spent here and now… he was an asset to be cultivated. That's why, even as the two 'battle' for dominance in the ensuing sexual tussle, Serafall is holding back an awful lot, making sure not to completely overwhelm the human.
As a result though, Aaron does wind up decimating her cervix and stretching out her womb again and again. Given Serafall was a virgin at the start of this, it's like nothing she's ever experienced before. There's an imnse pleasure in being womb-fucked right then and there on her back, even if its by a human man with a human's strength.
Clenching her teeth to hold back any moans, Serafall then proceeds to bare them as she looks up at Aaron challengingly, giving no signs of her pleasure away through her face despite him continuing to maul her tits.
"Harder!"
Harder he goes, as hard as he can really, until finally he can hold back no longer. Serafall feels the mont it happens too. She feels it as Aaron unloads his seed inside of her womb. She feels as his sperm is imdiately drawn to her inviting egg.
Serafall's eyes widen then and she's not quite able to hold back anymore as she feels every last bit of it. From the seed pouring into her, to Aaron's swimrs making the journey to her egg… and easily overwhelming its defenses and penetrating deep within.
In that mont, there's no doubt about what happens, at least to Satan Leviathan. She knows her body in ways that humans never could. She feels herself in ways that humans can't feel. As such, she can feel it as her egg is inseminated. She can feel it as Aaron manages to breed her right then and there, the entire process happening from start to finish on the spot.
As a result of this very, very detailed experience of her own impregnation, Serafall orgasms imdiately and intensely, the most intense and expansive climax of her entire life. The pleasure overwhelms her like nothing else so far has, making her thinly held together mask positively shatter.
Her pupils burst into hearts and she ahegaos her brains out on the spot, her eyes rolling back in her skull and her tongue lolling out of her mouth. Despite her vaunted self-control, despite her centuries of experience, Serafall, aka Magical Girl Levia-tan… breaks.
Fortunately for her, Aaron is in no position to take advantage of this fact. After flooding her womb and inseminating her eggs, he actually collapses on top of her before he can even see her fucked silly expression. Her tits cushion his fall as he lies there, panting heavily and trying his best to recover.
…
Then… a smug, bratty, and altogether lustful giggle breaks the silence. Before Aaron can react, Serafall has flipped them both over. Sure, he might have montarily broken her and made her ahegao from how good it felt to be bred by his cock, but she's STILL the Satan Leviathan!
Putting Aaron on his back, Serafall looms over the young magician with heart-shaped pupils gazing down at him and glowing ominously in a hot, lusty pink. Wiggling her hips, feeling his cock trying to go soft inside of her, Serafall moans throatily, not even trying to hold them back anymore.
"We're not done yet, Aaron. Don't you dare go soft on ~"
Luckily, her flexing cunt walls prevent that from happening and soon enough Aaron is rock hard once more. As soon as she's confident that he's ready for another round, Serafall lets out a lustful growl.
"Cast the spell again!"
Blinking, Aaron furrows his brow.
"Wha-? But… you're already pregnant… aren't you?"
He sounds actually worried, like now he's not sure if his spell worked. Serafall rolls her eyes at the lack of confidence.
"Oh yes, I'm very pregnant. Congratulations Aaron, you just knocked up. You've also just made yourself the most important human being in the entire universe, especially to and my people. And yet, I will make a Pact with you like you wanted. I'm not letting you go for ANYTHING, human~"
Aaron swallows thickly, even as Serafall leans in nice and close.
"Now… we're gonna see just how many babies you can pump into . So cast. The spell. Again."
When he opens his mouth to protest instead of doing as he's told, Serafall silences him by shoving her tits in his face. Luckily she doesn't have to do anything worse than that, because she really did want to keep a… friendly relationship with her baby daddy~
As it is, once he's got her breasts to contend with, Aaron doesn't resist much longer before moving his hands and casting the spell once more. Then, he starts to suckle and lick and bite at her tits, much to Serafall's imnse enjoynt as she feels another egg drop in her womb and begins to bounce up and down on his cock so more.
In the end, Serafall's ovaries drop four more eggs in total, each of which wind up easily and swiftly accepting the seed that she proceeds to milk from Aaron over the next several hours of fucking. anwhile, Aaron himself gets that Pact he wanted and all the power he could possibly hope for… while also becoming Satan Leviathan's kept magician pet.
To be fair, it's not like he really has anything to complain about. He gets his own personal mansion in the Underworld, complete with a private staff, security, and all the resources and equipnt he needs to develop more spells to his heart's content.
And every night he finds himself dragged into his new four poster bed where his balls are drained dry by the succubus that is the Satan Leviathan… even when she's heavily pregnant with his quintuplets. Not a bad life, all things considered~
