Sharp claws waved gently before Vitan's eyes, exuding a chilling aura.
Vitan simply chuckled, shook his head, then reached into the air beside him—space rippled slightly.
With a flick of his fingers, a completely blood-red object landed softly in Kuroka's hand.
"Mutated devil piece, my new master sure is generous."
Kuroka spread her palm open and looked at it, speaking with slight surprise.
"Even though the improvement isn't that great, raising you to the mid-tier of the Ultimate-class devils shouldn't be a problem."
Don't be fooled by how Kuroka and the Monkey King's descendant were suppressed by Vitan the entire time—these two were far from weak.
Take Kuroka for example.
The level of strength she displayed during her battle against the White Dragon Emperor, one of the strongest dragon-type beings, wasn't something a low-tier devil could even dream of matching.
The same went for Bikou.
While it seemed like he didn't do much the whole time, being a descendant of the Great Sage Equal to Heaven, it was obvious he inherited some of that sage's traits.
However, while both of them were undeniably strong, they had just stepped into the realm of Ultimate-class devils.
In contrast, Vitan had been delving into the power of Ultimate-class devils for quite some time now.
============
(T/N: I think I messed up the power level of MC in the earlier chapter. His not merely a High-class but already at the Ultimate-class with the battle of Sairaorg.
Its not really my fault tho cuz of how messy the author write this fic.)
============
He was only a step away from reaching true Maou (Devil King) level. Compared to him, the two of them—even combined—still weren't quite on the same level.
"Truly at ease, huh. You better remember what I told you."
Without hesitation, Kuroka placed the devil piece she held into her chest.
Vitan also raised his hand at the same time, and the magic circle beneath them began to glow.
As the magic circle gradually stabilized, the red light it emitted became more and more intense and blinding.
Then, like it was sinking into a bottomless swamp, the devil piece began to slowly melt into Kuroka's chest.
Bang—!
The moment the red light of the magic circle dissipated, a pair of dark wings unfurled from Kuroka's back.
"Never thought I'd have a chance to spread these wings again."
"But it actually doesn't feel too bad, does it?"
She slowly walked over to Vita. Seeing her approach, Vitan teasingly caressed the membrane of Kuroka's wing with a teasing look.
"Nyaau~!"
Kuroka let out a pained yet aroused cry as her wings twitched slightly in response.
"Hey, that's not my fault. Who would've thought a nekomata's sensitive spot wouldn't be the ears, but the wing membrane?"
Vitan had a totally innocent expression. This time, he really didn't have any ulterior motives—he just wanted to greet his new companion a little more affectionately.
…
"But still, this isn't a bad feeling either. Doesn't my new master feel the urge to do something more?"
Kuroka provocatively leaned close to Vitan, exhaling her warm breath onto his neck, and her soft chest pressed directly against his torso.
An itchy sensation instantly struck Vitan's heart.
Even he couldn't help but admit—when it came to charm, cat yokai and fox yokai weren't any weaker than the succubi trained in the underworld.
And now that Kuroka had become his peerage member, her inherent seductive qualities as a cat demon had grown even stronger.
"Not that I mind doing it now, but wouldn't it be a little awkward if the kitten next door heard us going at it? Koneko should be waking up soon. Are you really okay with letting your younger sister hear you like this?"
He wrapped one arm around Kuroka's waist and whispered while gently flicking her cat ears.
"How much time do we have, nya~?"
She slowly raised one of her plump, snowy thighs and slid it between Vitan's legs.
"Probably only about half an hour."
"My, my. Looks like my new master is very confident in himself."
Slap—!
Vitan's lips twitched slightly. Then he suddenly raised his hand and gave her a firm smack.
"I'm not letting that slide. You little wild cat—are you trying to provoke me?"
"Of course~ I'm very confident when it comes to seducing men."
"I doesn't believe you can last that long."
Vitan fell silent for a moment. Then he bent down, slipped one arm under Kuroka's thighs, and directly carried her up in a bridal hold.
He spoke in a menacing tone,
"Remember, this was your choice. Don't come crying later. Even if you beg, I won't stop."
"Like I ever would!"
Kuroka pouted while stubbornly clinging to his neck.
With a heavy slam, the door of the room Rias had specially prepared for Vitan finally fulfilled its intended purpose today.
==========================
(The following smut is written by me, obviously.)
When the door closed, Vitan quickly got down to business.
With no regards of what will Kuroka think, he forcefully stuck his tongue inside Kuroka's mouth, earning a gasp of surprise from the nekomata.
Their tongues intertwined with each other. Kuroka, who had a more sensitive body, began to let out small moans.
They continued their tongue dance until they had no air left. Vitan slowly separated from Kuroka and gave her supple butt a firm smack.
"Hmmnnnghh~~"
This seemed to have awoken her a bit, she let out another moan. Seing her dazed expression, Vitan couldn't help but comment,
"Hahahaha, where's the confidence now kitty cat?"
Kuroka was not one to back down, even though her pride was wounded a bit. "Ohh, I was just surprised that you're quite good at kissing."
"That was not a kiss, it was just my way of eating you up." Vitan simply gave her another smack. "Moreover, you really think you can take on the great-grandson of the original Asmodeus?"
"I'll have you know, a nekoshou in heat is not something just someone can handle, even if the one handling it is a devil itself, nya~."
"Hahaha, we'll see."
Along with that, he pushed her to the infirmary bed.
Before could Kuroka voice out her complain, Vitan tore the upper part of what Kuroka was wearing, freeing the bountiful mass of supple flesh with pink tips on the top.
Seeing the tantalizing view in front of him, Vitan roughly grope Kuroka's tits as if milking her.
"Nyaaaaaaaa~~~"
It illicit a sensual moan from the kitten's mouth. Seeing how loud she can be, Vitan bring up a barrier to not let anyone outside hear the lewd act they're performing.
Once that done, he brought up his mouth and suck the left breast like a baby.
"Ahh~~ Nyaaaa~~"
Her meows and moans echoed throughout the room. Her eyes was clouded by lust and her mouth was drooling.
Vitan's hand did not stay idle either, it slowly worked its way down to Kuroka's sopping wet panties and rubbed her pussy.
"Haa~haa~haa~, ahhhh~, ahhhhh~~"
Her moans grew louder and louder, it seemed like she was already nearing her climax.
As if sensing Kuroka reaching her peak, he bit down on her nipple while having his middle and index finger push deeper to her soppy covered cave.
"Nyyaaaa~~, I'm cumming, ahhh~~~"
After a while, she let out a loud scream of pleasure as her fluids gushed out like a broken faucet, staining the bed.
Vitan did not let up and continued to pump his fingers.
"Ahh~~ Ahhh~, no~~ I've already came once, nooo~~"
Kuroka cried out, desperately shoving his arms away from her entrance but her weakened state proved no resistance. As he continue pumping his fingers, the nekoshou in his arms can only helplessly moan and cum, over and over.
Seeing the messy state Kuroka was in, a smile full of lust and amusement played in Vitan's lips.
It was worth mentioning that this cat was so full of herself when she was throwing herself to him just a moment ago, when she can't even handle this level of foreplay.
Vitan got up, he unbuckled his pants, freeing a 8.5 inch dick with throbbing veins running along its girth. If Kuroka was in an okay state and saw this thing just shy away to be comparable to her forearm, she might double take and step back.
...That is if she was in a good state.
Good thing she's not.
Seeing Kuroka still in her own little world, Vitan roughly grabbed her panties, ripping it with ease.
Her pink and wet entrance was revealed, a little bit of her honey dripping down.
This jolted Kuroka awake.
Seeing that action finally get a response, Vitan smirked. He did not care what Kuroka would think, instead he brought his tip near her entrance, making her shiver.
"Ahh~~, haaahhh~, no, wait, c-can we just like, rest for a bi- Nyaaaaauuuuuhh~~~ "
He rammed his dick straight in, not caring for the little blood that ooze out from her pussy.
He roughly thrusted in and out, the lewd sound of flesh meeting flesh was loud in the room. Kuroka was overwhelmed by the pleasure and pain, her earlier confidence banished without a trace.
"You, nyaaa, hmph, you, ahh, stopp, ahhh, pleawsee, ahh, I begged, nyaaa~~"
"Stop? Why stop now? You want strong children right? I'll pump you with seeds that will last for generations to come!"
Vitan said, still piston fucking the living out of Kuroka.
"Haaaa~~, I don't, ahh, nyaa, care, ah, anymore, ahh, ah, just, ahh, make, ahh, me, ahhh, nyaaaa, into, ahhh, a m-m-m-m-m-ma-ma-ma-ma, nyyyyaaaaa, ahhh~~"
Vitan grinned,
"With pleasure~"
While still madly thrusting with wild abandon befitting of a devil, he rotated Kuroka on her stomach, revealing her two tails that are quivering.
Seeing how cute that was, he grabbed the two and pull hard, just enough to give pleasure and pain.
With a loud cry, Kuroka finally reached her fourth orgasm for the day. Vitan did not even wait for her to come down from her high as he continued ramming her.
"Nyyyaaaaa, hic, ahh, ahh, ahah, ahh, ah, ahh, a-a-again, nooo, ah, ah, ahh, a-a-again~~"
Another minute passed and Kuroka was again feeling her orgasm imminent, Vitan also nearing his peak, clenched his core and bit to Kuroka's fluffy ear.
"Nyaaaaaaaahhhhh~"
"Take it!!! the kittens you need are inside this cum!!!"
With a roar, he fired a torrent of baby batter. It was so much that some started seeping out from Kuroka's entrance.
"Nyaaaaauuuu~"
Kuroka cried again as she came for the fifth time. She can only pant, her mind hazy, her ears and tail droopy.
"Your mine, Kuroka, my personal kitten."
Vitan whispered as he slowly pulled his cock away, letting the seeds fall on the infirmary's bed.
With this only being witnessed by one grimoire that softly noted of what miraculous things you can do in less than 30 minutes.
==========================
People bustled along the cobblestone road, with women in kimonos and tourists sightseeing all around.
At the top of a massive sixty-meter-tall castle-like building reminiscent of the Warring States period, a spatial distortion suddenly emerged.
From within the black, inky teleportation magic circle that appeared at the tower's peak, a young man with a face resembling a monkey stepped out.
"Phew, that was close, really close. Good thing we ran away in time—otherwise, we'd both be prisoners by now."
"Right, Kuro—huh?"
The Bikou wiped nonexistent sweat from his brow and spoke toward his side.
"…Kuroka?"
After receiving no response for a long time, he turned to look…
And then fell completely silent.
"Dammit, I need to report this to Vali as soon as possible."
Bikou scratched his jaw, then leaped into the air, stepping onto a fluffy white cloud, and quickly flew westward.
