Commission

Themes: Big Dick, Dom/Sub, Breeding

Summary: Shouta is sick and tired of Lucoa's provocations. Fortunately, he finds the recipe for a potion that is said to be capable of 'taming a succubus'.

-x-X-x-

“Finally, it’s done.”
 
Shouta Magatsuchi almost reverently pours the potion he’s just finished crafting into a vial. It had been an arduous, hours-long affair, but he’d managed it… and before Lucoa could arrive back home too! A small smile flickers across the boy’s face at his triumph. He’d actually finished it… honestly, he hadn’t been sure he would be able to, not before Lucoa arrived to ruin everything just like she always did.
 
He wasn’t an idiot, you know. He was well aware that he brought it on himself. Maybe before his Quetzalcoatl’s (Lucoa for short) arrival, he hadn’t been very self-aware. But ever since she’d come into his life, Shouta’s own deficiencies had become rather clear to him. He was shy, timid, and quiet to a fault. And even though he was born into a family of mages and had plenty of training in the arcane arts, all he could do when Lucoa teased him and threatened to take his innocence was run away in embarrassment.
 
No more though. No more. He’d been pouring over an ancient tome in the family library when he’d come across the instructions for a certain potion that was said to give its imbiber the power to tame a ‘succubus’. It wasn’t speaking on just demons either, Shouta had made sure of that when he’d translated the old text. No, it was talking about willful and lusty women of all sorts of shapes and sizes, the type who didn’t know the meaning of the word ‘demure’ and who couldn’t be left to their own devices.
 
Now to be clear, under normal circumstances, Shouta would never make what sounded like some sort of mind control potion. Indeed, if the potion had required Lucoa to imbibe it, he would never have had the confidence to try this at all. But put bluntly, Shouta was at the end of his rope. And so long as it was just him, he was willing to risk it. Besides, if the potion really did give him mind control powers, he would simply have to be very considerate, very responsible, and very calculating on how he used them!
 
… He was stalling, wasn’t he? There’s no reason to wait any longer. The potion is done and all that’s left is for Shouta to drink it. Before Lucoa gets home and does something stupid like drink it herself.
 
That’s the thought that finally tips him over the edge, truth be told. Shouta blanches at the mental image of Lucoa stumbling upon the potion, drinking it in one gulp like the lush she is, and then having the ability to command him or something nightmarish like that. Quick as he can, the boy snatches up the potion he just crafted and quickly drinks it down.
 
Fortunately, it doesn’t taste too bad. Doesn’t taste all that good either to be fair, but he doesn’t let any of it leave his mouth, swallowing every last drop in record time before heaving out a huge breath as he sets the vial down… and waits.
 
He’s expecting to feel something, maybe in his mind? Like an awareness expanding or something? Except… that doesn’t happen.
 
“Shoooouta! I’m hooooome~”
 
Speak of the devil and she shall appear. Just as the massively busty and voluptuous blonde dragon comes walking into the room, Shouta feels a change coming over him. But not in his head… or at least, not in his upper head anyways.
 
Shouta’s eyes widen as he glances down at his crotch, suddenly feeling a straining like he’s never felt before. Even though Lucoa has literally just walked into the room, he scrambles to his feet and hurriedly strips off his pants and underwear. If he didn’t, he was afraid that they would have ripped and torn off of him anyways, because his cock is rapidly growing until he’s sporting a massive, throbbing, pulsating bitch breaker.
 
“S-Shouta?”
 
Gaping down at his cock, Shouta looks up to see Lucoa also staring at his member with her mouth wide open. He’s never actually seen her flustered or in a state of shock before. He kind of likes that look on her face. But… he’d like it even better if there was something in that open mouth of hers.
 
Suddenly feeling like ten million yen, Shouta stomps across the room to Lucoa and then growls because while his cock has gotten absolutely huge, he himself is still the same size as ever.
 
“Kneel.”
 
His voice is gruff and dark and husky as he insistently points to Lucoa’s feet. He’s pleased when she immediately obeys, dropping down to her knees without a hint of resistance. Only… he’s confident that the potion didn’t do what he thought it would. He doesn’t feel like he has any new ability to control minds. He doesn’t feel like he’s any more persuasive than before.
 
No… Lucoa is just such a fucking teasing slut that she’s already become enamored with his cock and will do anything he says to get her hands on it. Not that he’s going to let her.
 
Rather than allow Lucoa to grab his dick like she’s currently reaching to do, Shouta reaches up and grabs her by the horns instead. Then, he yanks hard while taking a step back. His firm grip on her horns means that Lucoa yelps as she suddenly finds herself on all fours, her hands slapping down on the floor to steady herself.
 
Just on her knees, Lucoa was still too tall to suck his cock. But now that she’s on her hands AND knees…
 
“Take it, bitch!”
 
He thrusts forward without hesitation, his cock slamming home into Lucoa’s open mouth right there on the spot. Her mismatched eyes widen as the big breasted blonde dragon chokes on his newly enhanced shaft.
 
“Gaaaaagkh!”
 
Without missing a beat, Shouta begins to thrust his hips back and forth. He feels filled with a strength and stamina he’s never had before… no doubt a side effect of the potion. A distant, logical part of his mind notes that the confidence and arousal he’s feeling right now are also probably a side effect of the potion. The fact is, he’s on a rampage, horny beyond belief.
 
… If he hadn’t had Lucoa here so soon, Shouta might have rushed out of this room and forced himself on the first woman he laid eyes on. Luckily for him, he has a willing fuck doll right here to take out all of his sexual frustration and arousal on.
 
“Gagkh! Gagkh! Gagkh!”
 
Using his grip on her horns to hold her head steady, Shouta wastes no time fucking Lucoa’s face. Those mismatched eyes of hers seem torn between looking at him and looking down at his cock, even as she gurgles, chokes, gags… and moans along his dick. She’s loving this, Shouta quickly realizes. The bitch really is a succubus, to even be enjoying it when he’s ravaging her like a beast!
 
Growling and snarling like an animal too, Shouta shudders in barely contained fury. All of this time spent running from Lucoa. All of the embarrassment she caused him… he wasn’t going to forgive her easily, no sir. He was going to fucking destroy her!
 
“Take it! Take it, take it, take it!”
 
“GAGKH! GAGKH! GAGKH!”
 
Graduating from face fucking to skull fucking, Shouta’s grip on Lucoa’s horns tightens up as he doesn’t just use them to hold her in place, but fully pulls her down his massive length with every thrust he sends forward. Burying his cock in her esophagus and gullet, railing her throat like it’s his own personal onahole, the young mage grits his teeth as he doesn’t let up for even a moment.
 
Until finally… he can’t hold back any more. His balls have grown with his cock, Shouta belatedly realizes. Otherwise, he probably would have shot his load almost immediately after he started fucking Lucoa’s face. But no, he had a gargantuan nut sack to go with his gargantuan member, and as a result, he’d had a lot more time to fill his balls to the brim with churning seed.
 
But now, he’s tipped over an edge… and is cumming a torrent right down Lucoa’s gullet. As her eyes widen, her nostrils flare, and her cheeks expand outwards, Shouta can’t really bring himself to care about her health in this moment. All that matters is his own pleasure.
 
To her credit though… Lucoa manages his load surprisingly well. Sure, some of his seed still winds up trickling out of her nostrils and the sides of her mouth, dribbling down to her chin. But the thing is, Shouta knows just how much he just came. For it to ONLY be that much was… well, a testament to how much Lucoa managed to swallow before he finally overwhelmed her. She got a good ninety-five percent of his load into her belly, and then couldn’t hold it back any longer.
 
Not that it mattered, because Shouta wasn’t done yet. Using his grip on her horns, Shouta doesn’t just let go… he throws them away from himself. This in turn throws Lucoa’s head and upper body backwards, causing her to go from on all fours to sprawled on her back. The perfect position.
 
Tossing himself at the delirious, insensate blonde, Shouta rips her top off first, and then also her shorts for good measure. The clothing comes away like tissue paper, revealing that enhanced strength and stamina were definitely side effects of the potion. He hadn’t been nearly this strong before. And… he was still hard too.
 
Lucoa at least has the presence of mind to spread her legs open as she shudders, still recovering from the relentless face fucking he’d given her. Not that it mattered whether she did or not, truth be told. Shouta would have just spread them himself. His hands grab at her thighs and he brings his cock to bear on her pussy… and a moment later he’s deep inside of her.
 
No hesitation, no foreplay, no mercy. He needs this… and luckily, she does too. Lucoa’s eyes finally focus again as she looks at him, a wanton moan torn from her parted lips. The trickles of his seed already drying on her face, she shudders and shakes while he pounds her sloppy, sopping wet cunt into the shape of his brand new cock.
 
“S-Shouta… a-ah! S-So strong! So… m-manly!”
 
Huffing, Shouta reaches out and grabs her by her tits, giving the blonde’s breasts a nice hard squeeze as he fucks and fucks her.
 
“There’s gonna be some changes around here, Lucoa. You’re mine now, got it? You belong to me.”

The words flow out of him so easily, even though part of him knows it’s just the potion talking. Except… it’s not just the potion talking, now is it? For one, the potion’s effects didn’t have a duration according to the tome he’d read. They were permanent, which was why he’d had to source some really expensive ingredients and then spent all day crafting the damn thing.
 
So his cock was always going to be like this. He was always going to have stamina and strength out of this world. Shouta could only hope that his currently raging libido would eventually calm down, but he knew there was only one way that was going to happen… by fucking his lust away until he finally got his arousal under control.
 
Luckily for him, he has Lucoa for exactly that purpose.
 
“Yes! Fuck me, Shouta! I’m yours! Make me y-your woman!”
 
With her squealing and climaxing all over his cock, Shouta just grunts as he goes harder and harder. He’s pistoning out of her fast already, but he isn’t going as deep as he possibly could… time to rectify that. He really starts driving into her, until he’s starting to hit the entrance of her womb itself. Pounding her cervix like his cock is a battering ram feels amazing, both for Shouta and for Lucoa.
 
Tossing her head back, her eyes rolling up in her skull, Lucoa squeals as she cums for him, orgasming time and time again. All the while, he’s pistoning in and out of her, knowing he’s not going to stop until he finally gets what he wants. And that’s… release.
 
Of course, even when he finally tips over the edge, it’s not enough. He groans as he cums inside of Lucoa at long last, but truth be told… it barely even puts a dent in his raging libido. Growling lustfully, Shouta pumps his seed into Lucoa’s womb and then pulls out of the blonde, only to frown at his twitching, throbbing cock.
 
“Ah… ah… ah… Shouta, that was… amazing…”
 
He looks up into her eyes and then scoffs, grabbing her by the hips and spinning her over onto her hands and knees again. This time however, she’s facing away from him.
 
“Silly bitch. Did you think we were done?”
 
He doesn’t give her a chance to respond before he slams right back into her again and starts pumping away like there’s no tomorrow. Frankly, at the rate they’re going, they might still be fucking when tomorrow comes. Because Shouta is just getting started.
 
-x-X-x-
 
“Oh! Looks like the father of my child is hard at work~”
 
As a pair of familiar tits press against the back of his head, resting on his shoulders while their ‘wielder’ hugs him from behind, Shouta just sighs. Even after everything that happened, Lucoa still insisted on teasing him. She just had new ammo for it these days… something he can feel as the bump from the baby he put in her womb presses against his back from behind as well.
 
Standing before a table, Shouta doesn’t even bother looking up from his magecraft.
 
“Under the table. Now.”
 
“So forceful~”
 
Reaching back, he grabs one of Lucoa’s nipples with unerring accuracy and gives it a twist through her top.
 
“Now.”
 
“A-Ah! Yes sir!”
 
The difference between before and now was that Shouta didn’t take Lucoa’s shit lying down anymore. As well, Lucoa actually followed through these days. She sort of had to… Shouta was pretty much always hard or a simple teasing away from behind hard thanks to the potion he’d imbibed. It certainly had let him ‘tame a succubus’ heh… but at the same time, he couldn’t escape the facts. He needed constant relief.
 
Fortunately, Lucoa was there to provide it. As the pregnant blonde crawls under the table, she happily frees her tits from the confines of her shirt and his cock from the confines of his pants. Then, wrapping her breasts around his dick, she begins to give him a proper titjob.
 
As she moans wantonly, Shouta just smiles and gets back to work, racing against his own internal clock. After all, it’s only a matter of time before he has to set what he’s currently doing aside so that he can fuck his lusty, slutty blonde dragon into a puddle of their combined juices once more.
 
And frankly, he wouldn’t have it any other way.
