Summary: Part 5 of Unlimited Perversity. A week after Riser's utter humiliation, Issei discovers that the energy from his Boosted Gear leaks into the women of his harem when they have fun, ‘boosting’ their physical traits in areas they think they lack, such as Rias and Akeno getting fatter asses and Sona going up several cup sizes. Koneko and Asia, who want to be the perfect women for Issei, are more than willing to be test subjects for this, even though Issei says they don’t need to.
-x-X-x-
“You know, you two really don’t have to do this…”
Even to Issei’s ears, his words sound weak. Admittedly… he likes the two girls in front of him very much. Asia Argento and Koneko Toujou both look back at him with surprising amounts of determination and resolve in their eyes. Koneko’s cat ears even twitch as Asia pipes up, hands curled into fists at her sides.
“W-We want to, Issei! You need some… t-test subjects, and so we’ll be that f-for you!”
“… Yes.”
Ah, Koneko is as soft spoken as ever. Of course, the Rook is also very cold, normally. She rarely shows feelings or emotions, and even now she’s barely giving him any signals beyond acceptance for what they’re here to do today. It’s rather weird, in Issei’s humble opinion… but at the same time, he’s not one to look a gift horse in the mouth.
And besides, his harem plans were continuing apace, but that didn’t mean he wanted to leave a pair of his favorite girls behind in the dust! Not that Asia or Koneko had actually agreed to join his harem or anything like that. No, rather… this was all about testing the limits of his newly discovered powers.
Put simply, it had been a week since Issei had beaten Riser silly and fucked his mother, his sister, and his Queen right in front of the most important people in the Underworld. And… nothing had happened, regarding that. There’d been no consequences. Might makes right when it came to Devilkind, apparently, and Issei had plenty of might thanks to his perverse nature supercharging his devil magic something fierce.
Apparently, that bled into other things as well. Put simply, it turned out Issei wasn’t just lucky enough to be the most powerful Reincarnated Devil they’d ever seen due to his perverse nature. He also was lucky enough to have an incredibly rare Sacred Gear. Specifically, his Sacred Gear was the Boosted Gear, which housed an entity known as the Red Dragon Emperor, and was said to be one of the thirteen Longinus, Sacred Gears capable of killing even gods.
Not that Issei was intending on going around picking fights with or slaying any gods any time soon. Really, since finding out he had Boosted Gear, he’d mostly just been experimenting with it. However, that was where today’s tests came into play.
Apparently, the energy from his Boosted Gear, combined with his massive demonic power and presence, leaked into those around him. Specifically, those who spent the most time around him, which was of course the members of his harem. Whenever they had fun together, his demonic power and the Boosted Gear comingled to ‘boost’ the physical traits in the areas they felt they were most lacking.
As a result, things between Rias, Akeno, and Sona had actually become somewhat… equalized. Rias and Akeno’s asses had grown a fair bit fatter until they were on par with Sona’s spectacular dump truck of a derriere, while Sona had gone up a few cup sizes, until she was closer to what both Rias and Akeno were rocking.
Rias speculated that if Issei concentrated and trained up the ability enough, he would be able to do it on command, rather than it simply being a byproduct of sex. And somehow, she’d managed to rope Asia and Koneko into acting as his test subjects for such training! Although, the more he looks at the two girls… is it possible Rias didn’t have to manipulate them at all? Is it possible his friendship with both of them, as short as it’s been, is blinding him to their feelings for him?
… Naaaah! That can’t be it. Still, the pervert that Issei is refuses to let such an opportunity pass him by.
“R-Right. Alright… so then, where do we begin? Um, does one of you want to go first?”
Asia opens her mouth to speak, only for the words never to arrive, as Koneko cuts her off by suddenly yanking open her blouse. With a Rook’s strength, the buttons on the cat girl’s blouse go flying everywhere, exposing her small, pale chest underneath. She’s not wearing a bra, though whether that’s because she knew what they were doing today, or because she doesn’t need one, Issei couldn’t say.
Koneko’s tits are certainly quite small… the smallest he’s ever seen, in fact. Though Issei personally believes all oppai are spectacular, no matter their shape or size, he can see why Koneko might want to expand hers a bit. Leaving her chest naked, Koneko turns her face to the side, her cheeks a little bit rosier as she thrusts her small breasts out in his direction.
“Right… okay…”
Reaching out, Issei grabs Koneko’s tits and begins… well, molesting them. He tries to focus his power into her boobs, just like Rias suggested, attempting to make her tits bigger through sheer force of will. Something stirs within him… and after a moment he realizes that ‘something’ is his cock. He groans, his cock straining against the confines of his pants as he shudders in need.
“S-Sorry, Koneko… I don’t think I can help you without… well, without us going all the way.”
He begins to regretfully pull his hands back. There’s no way Koneko would want to have sex with him, righ-?
But before he can release her small chest, her own hands grab his wrists and hold him fast.
“Okay.”
Issei can scarcely believe his ears… but pervert that he is, he also can’t hold himself back. The moment he processes that he’s been given permission, he’s upon Koneko. She squeaks when he kisses her, and squirms a bit, but doesn’t try to stop him. Rather, her hands go down below instead, and she hurries to extract his cock from its confines.
They end up on the couch, with Koneko on her back as Issei slides into place between her legs. His hands are still latched onto her tits, even as his throbbing cockhead presses against her surprisingly wet snatch.
“Koneko… you’re so wet. Is it possible… c-could it be… you wanted this all along?”
Koneko blushes profusely, her façade finally snapping as she scowls and pouts cutely while looking away.
“P-Pervert…”
But she doesn’t deny it. And as Issei slowly thrusts into her, taking her virginity and sinking into her depths inch by inch, Koneko moans, quivering and shaking underneath him. Now that there’s a connection between them, Issei can feel it more clearly. The relationship between his demonic power and the Boosted Gear, and more importantly the young Nekomata beneath him. Groaning, he pushes his energy forward into Koneko’s chest… and her breasts begin to rise beneath his hands.
It's VERY slow going. Something tells Issei that this ability is VERY power intensive, and that he’s doing something pretty wild by altering Koneko’s body in this way. He can feel how the rest of her is slowly transforming to compensate as well. You can’t just bolt a pair of massive tits onto a small cat girl and expect it to make sense, after all. She needs the infrastructure and foundation, so to speak, and she’s getting that, even as he fucks her tight cunt hard and fast.
Koneko’s wanton moans fill the room and are like music to his ears, but he hears something else as well… the mewling whimpers of the other girl in the room. Looking over, Issei’s eyes widen at the sight of Asia, dressed in only her white veil headdress, wearing nothing else and… and shamefully touching herself to the sight of him and Koneko going at it.
The sight of a former holy woman turned devil going to town on herself, despite Issei knowing Asia to still be a virgin… is so delightfully sinful that the devil feels a powerful surge go through him, and a lust filled, monstrous growl leaves his lips as he picks up the pace even more, fucking Koneko harder and faster than ever before.
The cat girl squeals and shudders as she orgasms on his cock, her tits continuing to grow even now. They’re plenty big enough by this point though, so Issei moves his hands to her hips instead, wanting to even out her body a little bit. Koneko doesn’t mind one bit, his grip on her hips making her moan wantonly as she shudders uncontrollably beneath him, cumming again and again and clenching down around his thrusting, pistoning prick the whole time.
Her cat ears twitch atop her head, and her twin cat tails writhe underneath her. Issei, for his part, can’t possibly let up, not now. This right here… this is everything, and with a triumphant roar, he slams forward into Koneko one last time and fills her with his seed.
When he finally pulls out and gazes upon what he wrought a moment later, Issei’s perverted sensibilities tell him he’s created a work of art. Indeed, whereas previously Koneko was a petite thing, small in all the right places… now she’s a veritable short stack, still quite tiny compared to Rias or Akeno’s heights, but much larger in the chest and hip region than she was previously.
No sooner has Issei gotten a moment to enjoy what he’s created, then Asia tackles him back onto the couch, sending him into a seated position as she eagerly straddles his crotch and rides him, kissing him insistently. His cock isn’t quite inside of her yet, but she is hot dogging his length with her pussy lips, even as she moans into his mouth, her arms wrapped around his neck.
They makeout like that for a little bit, just enjoying each other’s company, but eventually, Asia does have to pull back for air, and the two of them stare at each other for a brief moment, panting noisily as Issei smiles a wide grin.
“And what do you want me to do to you, Asia?”
Blushing prettily, Asia glances over at Koneko… and then comes to a decision, nodding decisively.
“I w-want what you did for her. Please… I want to be a momma. I want to be the mother of y-your children, Issei.”
Issei’s eyes widen at that, her sudden declaration taking him by surprise. Weren’t they just talking about enlarging some body parts here?! But no, Asia has the right of it…
“I need to have b-birthing hips… and sizable breasts for our f-future children to suckle from. So please… don’t hold back, Issei~”
Well, when Asia put it like that, what was a man to do but give her exactly what she wanted? Reaching around, Issei grabs Asia by her pert little behind and lifts the blonde nun up into the air. A moment later, and she’s slowly but surely sliding down his length. She squeaks and squirms, but only hastens her descent, and even with how tight she is, she’s assuredly wet enough for his cock to stretch her out, inch by inch.
Eventually, they go right through her hymen as well, and Issei claims his second virginity of the day. But it’s really nothing more than a moment before they’re back to enjoying themselves immensely with one another’s bodies. As Issei bounces Asia up and down on his cock and she in turn rides him while moaning and mewling and caressing his face with her hands, he grinds his fingers into her ass and hips.
Growing her buttocks and widening her hips to give her the perfect ‘birthing’ hips is easy enough… but Asia also wants breasts a little bigger as well, to be able to breastfeed their future children. The very thought of her growing heavy with his kids, of ALL of them growing heavy with his kids, fills Issei with a certain level of glee. He wants that, he decides in that moment. He wants that to become a reality.
But he only has the two hands, and they’re currently occupied with growing Asia’s hips and ass, aren’t they? Well, there’s nothing to it. He’ll just have to break out his secret weapon, if he wants to tackle her oppai as well! With a cheesy grin, Issei lowers his mouth to Asia’s breasts and takes the first of her teats into his mouth.
Asia squeaks, as he begins to suckle on both of her nips, one after the other. Focusing on his demonic energy as he does so, Issei uses his powers for good… for the good of him and Asia and their future children, that is! By alternating between her glorious oppai one after the other, Issei is able to keep the growth to a proper rate for both. Indeed, he grows them half a cup at a time, making sure they stay close to each other in size, not wanting to give Asia a lopsided chest.
Not that there’s anything wrong with a LITTLE asymmetry so long as it’s natural but having one boob be one cup size and the other be a different cup size… would just be plain weird. As it is, Issei fucks Asia from below and the blonde nun mewls and moans as she cums again and again upon his cock. All the while, her body transforms into their ideal vision of it, the two of them sharing the load so to speak.
When Issei finally pulls away from her tits, they’re a respectable size, perfect for breastfeeding. Likewise, her hips are wide now, and her thighs and ass thicc as all hell. She doesn’t look like a cute, innocent nun anymore. No, now she looks like the horny, needy, devilish seductress she’s become.
Gazing down at herself, Asia… smiles, a growing grin that makes her look even more devilish as she tosses her head back and laughs.
“Y-Yes, Issei! J-Just like this! Now… fill me up! B-Breed me! Pump me full of your seed and make me a mother!”
Issei groans, unable to hold back a moment longer. His seed pumps up into Asia’s womb, just as it did Koneko. Just as he’d been doing to all of his harem members, in fact. Hm, were they all pregnant by now? Or would he have to try harder to make it a reality? Either way, Issei creampies Asia Argento and she shudders atop his cock, climaxing hard all the way through.
And when all is said and done and she pulls herself off of his cock, both her and Koneko get down on their knees between his legs, using their new assets to rub his messy cock down before cleaning it off with their mouths and tongues. All the while, their eyes remain fixed on Issei’s face, making their adoration and devotion towards him obvious.
Looked like things had gone a little beyond mere test subjects. Indeed, it seems Issei has another two members for his growing harem…

Issei
Awesome! Normally not a fan of body modification. Makes it hard for me to picture what’s happening. But this works out. Helps that Koneko has a Shirone form that is basically her more grown up
