Summary: In which Issei gets turned into a woman and then converted into an Incubus' slutty little broodmare.

Generally, one would assume that trying to steal from Azazel, the Governor General of the Grigori, would be a foolish proposition. But that ignored a few key factors. Number One, Azazel had been willingly sealed along with the rest of the former faction leaders in order to stop Trihexa. Number Two, while many of the former Governor General’s holdings had fallen under the control of his subordinates and were thus still completely contained and well-defended, one particular location had not been… namely, Azazel’s classroom and subsequent storage room at one Kuoh Academy.
 
The lowest of low security areas, there wasn’t even a camera on the door to the storage room as a shadowy figure crept up on it, grabbed the handle, and subsequently tore the door open with inhuman strength. Stepping inside, the shadowy figure rummages around for a little while before finally making a noise of excitement and discovery. In the storage room’s dim light, the discovery can be seen in the figure’s hands… a ray gun with the abilities to swap someone’s genders with one shot.
 
Considered a ‘harmless’ invention by the sealed Governor General, it was left here at Kuoh Academy in a box of all places, despite Azazel telling everyone that he had carefully secured it due to its inappropriate nature. And to be fair, he’d totally meant to! He’d just never gotten around to it. More important things had continually grabbed his attention, until quite abruptly, he’d run out of time.
 
The shadowy figure chuckles darkly as he holds the gender-changing ray gun aloft in his hands almost reverently. And then, like the thief in the night he is, he turns and makes his way back out of the storage room, not even bothering to fix the door on his way out. But then to be fair, no one even comes around to this part of the Academy any longer. It would be years before a new teacher would be assigned to Azazel’s old classroom and subsequently discover the broken lock on the storage room door.
 
And by then it would be much too late…

It happens so fast that Issei takes a moment to even register it. One moment he’s walking along on his lonesome… and the next, SHE is standing there, baffled and confused by the fact that she’s suddenly a woman. Blinking owlishly, Issei Hyoudou looks down at herself… and her eyes boggle at the sight of her new breasts.
 
Some of the biggest she’s ever seen (and that’s saying something) the massive oppai that the brunette is now sporting strain against her top until suddenly, her shirt-
 
RIIIIIIIIIIIP~
 
-bursts open, buttons flying everywhere as her tits, not contained by any bra of course, go bouncing and jiggling all over the place. For a long moment, Issei just stares at her fat titties… before giggling perversely and giving into her debauched nature. Right there on the street, she starts to play with her huge chest, fondling her oppai out in the open for all to see.
 
As a result, she’s so distracted by her own body that Issei doesn’t even notice her attacker until he’s right behind her. The first sign the transformed young woman gets that something is truly wrong is when a pair of erroneous arms suddenly wraps around her torso and gropes her tits alongside her own hands.
 
“Eep!”
 
Letting out a very feminine, very girlish squeak, one that she’s only ever heard from her own victims before now, Kuon Town’s resident pervert leaps away from the pair of molesting hands, spinning about and entering a battle stance as she summoned Boosted Gear while her bare tits jiggle around.
 
Briefly, she feels Ddraig waking up in the back of her mind, drowsily checking to see what’s going on. However, when the Great Welsh sees her current state, she gets the distinct impression of exasperation and ‘fed up with this shit’ before Ddraig retreats into the deepest recesses of her soul so he doesn’t have to deal with her bullcrap.
 
That’s fine! Issei can handle whatever this is all on her own! She still has Boosted Gear and she’s a super duper strong fighter, so-!
 
But just as the brunette is hyping herself up… her mind goes foggy and her angry expression goes slack as she blinks and finds herself staring at the hottest, most handsome guy she’s ever laid eyes on. He gives her a wicked grin, twirling a very familiar ray gun in one hand.
 
“Hey there, gorgeous. The name’s Kiel. You don’t know me, but I know you. Here’s the rundown. I’m an Incubus. You’ve probably never heard of my kind, mostly because the Underworld likes to stamp us out as much as possible. Has to do with how dangerous we are, you see. Because no matter how powerful a female devil is… they catch one whiff of an Incubus’ musk, and they fall under our sway.”
 
His wicked grin turns momentarily rueful and he shakes his head.
 
“Of course, couldn’t do anything about the male devils killing off my kind to keep us from cucking them… until now. This little ray gun… it was imperfect, but I went ahead and completed it. Now it doesn’t just change someone’s physical gender, but also their mental gender. Making you just as susceptible to my musk as any other female devil.”
 
Normally, a bad guy monologuing for this long would be a surefire way to get himself fucked up and beaten seven ways to Sunday. But in this case… there’s no one else around. It’s just Kiel and Issei, and in her current state, her nostrils flaring as his scent fills her nose, Issei is in no mood to fight back.
 
Seeing this, Kiel sets the gender-swap ray gun aside and moves in closer, whistling low as he looks Issei’s swaying form up and down.
 
“I’ve been taught all my life to keep my head down and keep a low profile. I’ve had to make do with maids and nothing else. But I’m done hiding. And when I heard about you… I knew I had to have you. The Red Dragon Emperor, rising star in the Supernatural World, turned into my personal slut.”
 
His hands come down on Issei’s shoulders and she doesn’t even fight it as he pushes her down to her knees right in front of him. Nor does she offer a single protest when Kiel whips his huge cock out and slaps it down onto her face. A concentrated dose of the Incubus’ musk fills Issei’s nostrils, causing her mind to grow even foggier… and her lust to be truly awakened. Her libido goes through the roof as she moans wantonly.
 
In the end, Kiel doesn’t have to do anything more. Issei happily, giddily even, reaches down and grabs her new honking tits, wrapping them around his cock. Despite being so huge, her breasts still barely manage to enclose the Incubus’ big fat dick and she ultimately has to take the top half of Kiel’s shaft into her mouth as it sticks right out of the top of her brand new cleavage.
 
Not that Issei minds that one bit. She moans around his cockhead and quickly begins to suck his dick while also fucking her tits with the huge-ass schlong. It quickly becomes her entire world. Even better than playing with her tits… is using her tits to satisfy this handsome hunk. He’s so awesome, so cool… and so fucking sexy.
 
“Glughk! Glughk! Glughk!”
 
He’s also so damn big that even with half of his shaft wrapped up in her massive mammaries, Issei is still choking and gagging on the other half of his dick, face fucking herself on his member.
 
For his part, Kiel groans and tosses his head back, shuddering in pleasure.
 
“H-Holy fuck… it’s hard to believe you were a guy a few minutes ago. You’re a fucking natural at this, bitch.”
 
She is indeed. Issei’s perverted nature had translated into her being a natural slut as a woman. And with a pair of jumbo jugs for a chest, she’s all too eager to use them to the best of her ability, to pleasure the hunky Incubus in front of her.
 
It’s not long before Kiel tips over the edge due to Issei’s enthusiasm. His eyes go crossed and he doubles over her, fisting his hands in her brunette locks as he begins to cum. To her credit, Issei doesn’t even hesitate to swallow every last drop of his jizz. She drinks down his load like she’s been doing it all her life, once again showing off how much of a natural slut she truly is by not spilling even a single drop.
 
Of course, even as she finishes draining his balls, Kiel straightens back up… and then all but tackles Issei to the ground. His cock doesn’t go soft for even a moment from giving up one single load of cum. He is an Incubus after all, sex is kind of his thing. Regardless, he quickly pushes Issei down onto her back and rips her pants off of her as well, removing her boxers just as quickly with his inhuman strength and exposing her gushing wet, virgin snatch to open air.
 
More importantly, he exposes her cunt to his cock, even as he folds her legs up over her body. His huge dick fits against Issei’s pussy lips and then he spears into her, filling her sopping slit with every last inch of his shaft. With how drenched Issei is, with how aroused she is, neither of them even really notices Kiel slamming right through her virginity.
 
It’s there one second and gone the next, obliterated by the Incubus’ huge member. Issei, meanwhile, is too busy crying out in ecstasy to even care that she’s just been deflowered. But then, even if she was in her right mind, the likelihood of her carrying about keeping her hymen intact would be quite infinitesimal.
 
“Fuck yeah. Fucking take it, bitch. Take my big fat cock. Submit to your new Master, slut!”
 
As he molds her pussy on his cock, Issei moans wantonly, groping at her own tits.
 
“Yessss… fuck me! FUCK ME SILLY!”
 
With a growl, Kiel does exactly that, pumping into her with all his might until eventually he’s rewarded by the most pleasing face that one of his lovers can make for him… that being the ahegao. Issei’s eyes roll back in her head and her tongue lolls out of her mouth as she continues to massage, knead, and maul her new oppai, moaning under him. Seeing the transformed Red Dragon Emperor making such a slutty expression only eggs Kiel on, making him growl all the more lustfully as he picks up the pace.
 
Flesh slapping against flesh and a cock squelching out of a welcoming cunt fill the street. Luckily no one is around to hear them as Issei Hyoudou is defiled right there on the side of the road. It’s very public, but not a single soul is there to see it, even as Kiel thoroughly turns Issei into his bitch. Until finally, unable to hold back any longer, the Incubus throws his head back and howls as he releases his second load.
 
His seed pours into the brunette’s clenching cunt, flowing into her womb and flooding it in mere moments. If Issei’s eyes weren’t already rolled back in her skull, if her tongue wasn’t already lolling out of her mouth, they definitely would have been now. As it is, Issei’s body just jerks and shudders as she orgasms explosively from the feeling of being so thoroughly creampied.
 
Letting out a sigh of contentment and satisfaction, Kiel grins as he begins to pull back out of his new conquest. He could have kept going of course, two loads was nothing to an Incubus… but given their current location, it was probably best to relocate. Just as he’s opening his mouth to tell his new pet this, however, something thoroughly unexpected happens.
 
In a burst of speed and strength that takes Kiel completely by surprise, Issei abruptly reverses their position, leaving the Incubus on his back and the big-breasted brunette on top of him, sinking back down his cock as a result. His eyes widen in shock and horror as he notices the red gauntlet still on one of the female devil’s arms, the green gem glowing with power.
 
How? How had she managed to overcome his musk?! It shouldn’t have been possible! Hell, even Serafall Leviathan should have fallen to an Incubus’ scent (though none were stupid enough to actually try that). So how?!
 
“Hey!”
 
Looking up into Issei’s eyes, Kiel expects anger, fury, and certain death headed his way. Instead… instead he sees a slightly manic grin on the brunette’s face, her eyes wide with excitement and enthusiasm.
 
“Girls’ breasts get bigger when they get pregnant, right?”
 
Blinking owlishly, Kiel slowly nods.
 
“… Yes?”
 
“Then I need to get pregnant ASAP so that I can get even bigger oppai! The biggest oppai around!”
 
It should be said, Issei was on record as saying that oppai of all sizes were just fine. That he liked them in every form they came in, big or small. But that was male Issei. FEMALE Issei had her own way of thinking, especially when it came to her own breasts. Grabbing hold of her massive tits, imagining them even bigger with a huge dopy grin on her face, the brunette Red Dragon Empress begins bouncing up and down on Kiel’s cock rather wildly, continuing to grope her own chest as she ahegaos some more upon his dick.
 
For a long moment, Kiel just lays under her, a little nonplussed. But then he thinks it over… and decides he’s perfectly fine with this. After all, his goal was to turn the strongest slut he could get his hands on into his bitch. And while Issei Hyoudou might not be the strongest YET, she had potential in spades and had shown such a rapid increase in power that he figured it was only a matter of time.
 
“Get me pregnant! Get me pregnant! Get me pregnant!”
 
Slamming herself down onto his dick again and again, her new ass and wide feminine hips jiggling and slapping away at his crotch, the brunette squeals as she begs him to breed her, to knock her up, demanding that he turn her into his broodmare just so her tits would get bigger.
 
It was obvious how addicted she’d become to his cock already… to his very presence. Aside from that momentary scare, Kiel realizes he’s done it. He’s turned this bitch into his own personal fuck slut.
 
Grinning wickedly, grabbing Issei by the hips and helping her out with her goal by thrusting up into her from below, Kiel decides he’s just fine with this. He’s going to let her milk his fat cock of thick, life-giving seed and fill her thirsty, fertile womb as many times as she wants~
