Grayfia's brain was seared by the pleasure she had never experienced, and her expression grew utterly shameless. Gone was the dignified Queen of the Demon King; all that remained was the figure of a female beast craving pleasure.
"I can't stand it! Rub there more! Grind it!!"
"Hmm, is this the spot?"
"Ah, no! I'm going to come again!!"
Doing as she begged, he moved his hips, grinding the head of his cock against the entrance to her womb again and again. Each time, Grayfia was sent over the edge.
Having that thick cock rubbed against a place her husband could never reach, her body was being rewritten—remade into one that could never again be satisfied even by the Demon King himself.
Her back arched like a drawn bow, her face a mask of ecstasy as the upper half of her body slumped weakly onto the floor. But Kazuki had no intention of letting her rest.
"Has your heart fallen? Or perhaps—"
He whispered the words near her ear before gripping her slender waist. As if declaring the foreplay was over, he pulled his shaft almost completely out, only to drive it back in with a single, powerful thrust, slamming right against her cervix.
"Fuaaaaaaaaaaah!!!!"
A coquettish cry, unlike any she had ever made before, spilled from her lips. It was so foreign that Grayfia herself wondered if it was truly her own voice.
The sound of flesh meeting flesh filled the air as their hips collided. With each fierce piston of his hips, her quivering depths were relentlessly scraped by the crown of his dick. Uncontrollable moans, incomparable pleasure.
It was more than enough to corrupt her mind and body.
"It's going so deep, coming in and out! I can't stop cumming!!"
Her words had become so broken she could barely speak coherently, yet Grayfia continued to climax.
Any guilt toward Sirzechs had all vanished from her mind. She could only think of reveling in the pleasure being given to her.
And the one providing it, the one fucking her now, was Kazuki Fuwa. This fact was being carved into her very soul. Thanks to Venelana, she had met a superior male and was now fulfilling her purpose as a female.
He took her in the missionary position, holding her close as he devoured her, sealing her lips with his own, plundering her mouth with his tongue.
"Mmmphhh! More, give me more!"
Kazuki flipped her into the cowgirl position, where she lewdly beckoned him, rocking her hips, only for him to thrust up into her even more powerfully.
"Ahhhh!!! That's hitting a different spot than before! This is incredible!!"
He lifted her into the so-called 'Ekiben' position, and she clung to him to keep from falling, pressing her ample breasts against his chest as he took her.
"It's going deeper than before! Nnaaaaaaah!! Kazuki's coooooooooock!!!"
For Grayfia, who had only ever faced Sirzechs in the missionary position, every one of these was a new experience.
As if instructing her, Kazuki continued to deliver pleasure in various positions, each intense sensation overwriting the memories of her husband like a stronger file saving over a weaker one.
As proof, the memories of her intimacy with Sirzechs within Grayfia's mind were beginning to grow hazy, as if a fog had settled over them.
The degree of pleasure given was simply too different.
On one hand, there was mutual love, but unsatisfactory pleasure. On the other, there was mind-searing pleasure, and her own body was being lewdly developed further and further.
"Who are you?"
"I am... Kazuki-sama's flesh slave. A maid who exists to enjoy the pleasure Kazuki-sama grants me and to serve my Master."
Though only a few hours had passed in reality, the waves of pleasure brought by Kazuki had caused Grayfia to rewrite her own sense of purpose.
She had convinced herself that her role was to serve her Master, Kazuki, and bring him pleasure as a maid and a sex slave. To any observer, it was clear Grayfia's heart had completely fallen for Kazuki.
"You did well, Grayfia."
"Yes. Kazuki-sama, I have a shameless request."
"Go ahead."
"Please fill my womb with your hot semen."
"Understood."
When Grayfia asked for Kazuki's hot seed, he nodded. He had her place her hands against the wall and stick out her ass, assuming a standing doggy-style position, before plunging his cock back into her depths.
He rubbed the head against her most sensitive spot over and over, each time causing her inner walls to spasm and her tight folds to clamp down fiercely on his shaft.
"Kazuki-sama, I-I'm... about to...!"
"It's fine. I'll match your timing."
Pounded fiercely, the MILF rode wave after wave of smaller climaxes, sensing one particularly massive one about to crash over her. Kazuki, who had promised to match her and release inside her, saw her nod, and the countdown to her peak began.
She felt his member swell even larger within her cunt as his pistoning motions grew faster.
"I'm coming... I'm cummmmmming!!"
The strongest contraction yet gripped Kazuki, and in perfect sync, a jet of hot seed erupted from the tip of his shaft, flooding Grayfia's inner depths.
Splurt Spllurt Spllrt Spurt Spuuuuuuuuuuurtt!!!!
The semen released deep inside filled her womb, and what couldn't be contained spilled out from her lower lips, staining the floor white.
"My Master's hot semen is filling me—fwaaaaah~!!!"
"It's a waste to let Kazuki's long-awaited seed go to waste, nya~!!" said the naughty cat who had been peeking all this time.
Kuroka brought her face close to Grayfia's dripping, creamy pussy, licking up the overflowing semen with her tongue to prevent any from being lost.
"Nghhh!!!" The sensation of her sensitive, freshly orgasmed folds being licked drew another wanton cry from Grayfia.
As if demanding more of Kazuki's cum, Kuroka brought her lips right to the entrance, repeatedly lapping up the seeping cum with her tongue.
"It's so sensitive right now... No, no, no, stahhhhp!"
"Mnyaah, so much came out, nya~!!!"
Kuroka continued licking until no more of the mixed love juice and semen spilled from Grayfia's pussy, then pulled back with a satisfied expression.
Kazuki's seed, tasted after so long, was a feast for her as well, thick with potent magic. Despite Grayfia's protests, Kuroka's relentless tongue drove her to yet another climax.
"I'll clean this side too, nya~... Fufu, a strong male is the best, nyaaah~!!!"
"If you do that, I might just go again, you know?"
"Mmph... In that case, I'll just... keep it in my mouth until it calms down, nya~n."
Taking Kazuki's massive cock into her mouth, Kuroka once again used her tongue to clean the glans and the frenulum, gathering the clinging love juice and semen.
She meticulously stimulated the area around the urethral opening with her tongue while sucking like a vacuum to draw out any remaining seed.
When she released him, she trailed her tongue along the shaft, thoroughly cleaning every last drop of fluid.
After the two showered to wash away sweat and other fluids, Kuroka embraced Kazuki from behind, pressing her ample breasts against his back, resting her chin on his shoulder, and whispering in his ear.
"So, Kazuki, you have really corrupted the Devil King's wife, and made her addicted to your cock, nya~?"
