Chapter 411 Greyfia ②*
Edited by: Kanaa-senpai
As life energy poured into them, two streams of mana-light emerged from the centers of their bodies.
One pale blue. One silver-white.
Before the peak pleasure had fully faded, Grayfia once more felt a soul-deep joy and exhilaration. Through Second Life Transformation, Aki had become a God-tier powerhouse—and his life energy and cultivation effects had undergone another enhancement.
The silver-haired beauty now felt not only physically filled, but emotionally full as well—the chains of obsession that had bound her for years gradually loosened under endless waves of sensation.
Her long-stagnant strength had advanced another notch. Even that unreachable threshold she’d always gazed at seemed now to materialize, blurred yet present, at the edge of her vision.
Meanwhile, for the first time in ages, Aki had done more than merely copy bloodlines and talents through his Talent Copy ability. This union of spirit and flesh—this shared cultivation—yielded visible, palpable gains.
His somewhat unsteady God-tier aura gradually stabilized as he absorbed decades of Grayfia’s Yin Essence, the two streams of blue and silver energy swirling and merging. Solidly, unmistakably, he took a step toward the realm of Mid-God.
Just as his path had shifted from Martial Way to Immortal Path, there were still many sub-levels below the Heavenly Immortal stage. So-called “God-tier” encompassed numerous gradations—the division into upper, middle, and lower classes was merely the most superficial one.
If you really got into the details, using this world’s classifications, there were roughly: God-tier, Main God-class, Dragon-class, Transcendent, High God…
It was complex. And because the very concept of Sacred Gear defied neat categorization, power levels lacked clear boundaries.
So within the instinctive framework of Aki’s Talent, he simply categorized them as upper, middle, and lower—aligning them with the Immortal Path’s realm structure for a more intuitive display of his current level.
Aki and Grayfia lay intertwined, savoring the gains from their Dual Cultivation. Joy swelled within them—but the restless flame in his heart began to burn anew.
One of them had been starved for years, having served as little more than a breeding vessel, never truly understanding what it meant to be loved in body and soul.
The other had just vanquished his Heart Demon and was now wrapped around the woman he’d longed for—there was simply no way this could end after one round.
Even though it was still daytime. Even though Grayfia had unfinished work. Even though the commotion of Aki’s earlier breakthrough had drawn countless eyes. The moment their first Dual Cultivation concluded, the two found themselves irresistibly drawn into a second fiery battle.
While they surrendered to passion and devoted themselves to cultivation, Venelana—who looked so much like Rias it was almost uncanny, differing only in hair color—had finally finished dealing with all the Devils who’d come knocking for information.
The matriarch of the Gremory household. A direct descendant of the House of Bael, one of the Pure-blooded Devil clans. Once hailed as a prodigy, now a lady of mature grace.
She sighed softly, rubbing her pale, smooth forehead with a touch of exasperation. Her long, ash-blonde hair swayed gently with the motion, every movement radiating composed elegance.
Alone for a moment as the irritation subsided, Venelana reached out with her senses again to check the cultivation chamber of her daughter-in-law.
”…Hm? That aura isn’t Grayfia’s—but it does feel somewhat familiar.”
The residual traces left by Aki’s breakthrough caught her attention. But the two had never interacted deeply, and she couldn’t place it.
She waited a little longer. Still, Grayfia made no move to come explain herself. Finally, the woman once known as the “Ash-Blond Lady of Extinction” could restrain herself no longer—and began walking toward her daughter-in-law’s quarters.
Passing through various areas along the way, the maidservants at work paused to offer respectful greetings, curiosity flickering in their eyes. Why was the mistress out patrolling during her usual naptime? But none dared ask.
Venelana nodded lightly, motioning for them to return to their duties.
The closer she drew to Grayfia’s room, the fewer maidservants she encountered. By the time she reached the end of the corridor, there was no one in sight.
As Head Maid, Grayfia not only managed the other maids but also had duties of her own—though far less demanding. And since she held a position that required her to work, she’d taken charge of her own living quarters.
Given her special status, no one without explicit reason ever came near.
The spotless corridor was utterly silent. Venelana closed in on her daughter-in-law’s bedroom. And the closer she got, the clearer the odd sounds became.
Breathing mixed with moans—as if someone were engaged in strenuous exercise… or enduring something against their will.
To casually probe with one’s senses was deeply rude, so Venelana had only done the bare minimum earlier. Moreover, she hadn’t enjoyed an active s*x life in years—or rather, she had deliberately suppressed that part of herself, refusing to even think about intimacy. As a result, she failed to immediately recognize the truth of the situation.
Standing at the door, the strange sounds grew more distinct. Venelana listened for a moment, feeling something stirring deep within—something on the verge of breaking through. A restless heat began to spread through her entire body.
Just as the feeling threatened to overwhelm her control, she dared not listen any longer. Instinctively, she raised her hand and knocked on the door.
Knock… knock…
”Grayfia? Are you in there?”
As Venelana’s gentle voice rang out, the strange sounds from inside abruptly stopped. After a long pause, two muffled, barely-suppressed groans drifted out in fragments.
The ash-blonde beauty’s cheeks flushed, her brows lightly furrowing as strange thoughts began to surface in her mind.
But she quickly banished them.
Grayfia was her daughter-in-law, the wife of the Underworld’s reigning Demon King, a Demon King-class powerhouse in her own right, hailed as the Strongest Queen and the Silver-Haired Exterminator. There was no way she’d be doing that in her own room…
…Right?
Could she be… relieving herself out of loneliness? Venelana thought of the occasional exercises she herself indulged in during late, sleepless nights. But even then—during broad daylight?
And besides, there was that unfamiliar aura in the room—identical to the presence that had burst from the cultivation chamber during that towering pillar of light, the mark of a God-tier breaker’s aura.
As her thoughts churned, Venelana called out again: “Grayfia?”
Inside the room, Venelana’s sudden arrival had pushed both Aki and Grayfia over the edge at the same moment. They hit a shared climax.
Fortunately, Aki reacted quickly, covering the silver-haired beauty’s mouth just in time—stopping her lewd cries from being fully exposed.
After a brief recovery, Aki released his hand from her pink lips so she could answer the question from outside. His c**k, however, remained buried deep inside her delicate, slick flower passage.
”U-uhm… Madam, is there something you need?” Grayfia fought to suppress the stimulation, keeping her voice as flat and serious as she could manage, just as she always did.
While she strained to handle Venelana’s sudden arrival, Aki slowly withdrew his still-erect c**k, then turned her voluptuous body over.
He moved behind the silver-haired beauty, cupping her round, supple, snow-white buttocks, positioning her toward the door so she could better answer Venelana’s questions. At the same time, his c**k—still slick with slippery fluids—pressed against her pink rosebud, its surface covered in fine, delicate wrinkles.
Feeling the hot, massive head slowly push into her virgin entrance, lubricated by bodily fluids, Grayfia looked back over her shoulder at Aki with a resentful, lingering gaze.
Her mouth’s first time had already been taken by him. Now, apparently, he wasn’t going to let her back door escape either—he was determined to claim that first time as well.
If Venelana weren’t just beyond that door, if Venelana weren’t her mother-in-law, Grayfia would have happily cooperated. But in this situation? She was almost paralyzed with tension—there was no room for any such frivolous mood.
But Aki paid no mind to the silver-haired beauty’s feelings. After the initial shock of fear had passed, the thought of the Ash-Blond Lady of Extinction standing just outside only made him more excited.
”Grayfia? You’re in there—may I come in?”
Hearing her daughter-in-law’s response, Venelana felt relieved, a little ashamed of her earlier wild imaginings.
”Ah… u-uh—”
At that moment, the silver-haired beauty was desperately covering her own mouth, feeling the fullness of the c**k forcing its way into her virgin rear. Barely, she managed to choke the lewd gasps back into her throat.
The thick, burning c**k sank in almost completely, pulsing and throbbing inside Grayfia’s tight, warm rosebud.
”Mmm…”
Bearing the discomfort of her back entrance, clamping tightly around that scorching invader, the silver-haired beauty opened her lips and replied in a slightly husky voice:
”I—I’m not conveniently… ah—forgive me, um… Madam, could whatever it is… wait until later?”
After a moment of thought, she couldn’t conjure any good excuse. So she simply said she wasn’t conveniently available, and let Venelana fill in the blanks with her imagination.
And indeed—though she found her daughter-in-law’s behavior a little odd, Venelana didn’t overthink it. She only asked with concern: “Are you all right? Are you feeling unwell?”
”N-no… thank you for your concern, Madam.”
”Are you sure? There’s no need to be polite with me. After all, you are my daughter-in-law…” Venelana’s voice hesitated. “It’s because of that aura that burst out earlier, isn’t it?”
At those words, Grayfia’s tension spiked—her newly breached rosebud clenched even tighter, hotter. “N-no… I’m really fine. That aura was Aki… it was the Red Dragon Emperor.”
”That boy?”
Venelana fell into thoughtful silence, mentally reviewing what she knew. Yes, it did seem like Aki’s aura—just grown so powerful it was unrecognizable.
Grayfia seized the opportunity to look back again at Aki, the mischief-maker, silently begging him to hurry up. If they dragged this out any longer, Venelana might well figure things out.
But Aki only wore an excited grin. Instead of pulling out and finishing quickly, he pressed in even deeper—then stopped moving entirely.
His intent was clear: he wanted Grayfia to do the work herself, to sway her wanton hips, to use her still-untried rear to milk his Life Essence out with her own effort.
With no other choice—and with her powerful mother-in-law just beyond the door—Grayfia reluctantly clamped her pink rosebud tighter, rolling her slender waist and full hips in an instinctive rhythm. Back and forth, back and forth, she began to take the thick purplish-red shaft into herself.
The rough, burning c**k rasped against the soft flesh of her insides, searing the thin membrane. As she actively pleasured Aki’s shaft, Grayfia gradually found herself feeling something building.
The silver-haired wife, already climaxed twice in her slick flower valley, began to respond again—secreting fresh rivulets of transparent, slippery honeyed fluid.
As the stinging, burning pain gradually faded and her virgin entrance adapted with surprising speed to its new role, Grayfia found the presence of that thick, hot invader increasingly… welcome. And she slowly realized that this new manner of love wasn’t so bad at all.
”Grayfia? What was that boy Aki doing in your cultivation chamber when he broke through? And it was a breakthrough to God-tier, wasn’t it?” Outside the door, Venelana snapped out of her reverie and asked again, then added with curiosity: “Are you available now? I’d like to come in and discuss this properly.”
In her mind, even if Grayfia had been inconvenient—doing something embarrassing—she’d have had time to clean up by now.
But the ash-blonde beauty could never have imagined that Grayfia was bold enough to be, just a door’s thickness away, essentially cuckolding Venelana herself with her own future son-in-law.
Actually, it wasn’t Grayfia’s boldness—it was Aki’s.
The silver-haired wife currently had no resistance against him whatsoever; she could only give whatever he demanded.
And Aki had long held ideas about this beautiful, sensual woman who looked no different from a young girl—save for her hair color, a mirror image of Rias, his fiancée’s mother. He’d planned to confess to her separately, just as he had done with Grayfia, regardless of success—to face his desires head-on.
But before he could make his move, the Ash-Blond Lady of Extinction—well, now she was more a matronly beauty—had practically delivered herself to his doorstep.
”Coming. Coming.” Grayfia shot Aki a reproachful look over her shoulder. Aki, understanding the urgency, gripped her hips and began actively thrusting into her rosebud.
The silver-haired wife’s rear passage was hot and tight, and before long, Aki felt himself approaching the edge. Under that constrictive squeeze, his c**k was on the verge of release.
So he drove it deep one last time, his jade orbs tightening, as he pumped hot spurts of thick, white Life Essence into her newly opened flower.

Summary:
Aki and Grayfia’s Dual Cultivation breakthrough has elevated both their powers, with Aki reaching Mid-God realm while Grayfia’s long-held emotional chains begin to loosen.
