Chapter 357 Mastering the Holy Sword


Edited by: Kanaa-senpai


 At this moment, Xenovia knew only to instinctively arch her back, lifting her soft, yielding Flower Valley to meet him, again and again.


 ”Nnh? Ugh… Aki? Is it… good? Mnn? Ugh?” Xenovia gasped, her voice trembling with the heavy, sweet tiredness of her peak.


 Gradually, the girl’s gasps faded into silence.


 Xenovia finally crested the peak. She went limp, letting her limbs splay as she collapsed onto the bed, utterly drained.


 Aki drove his Great Dragon deep into the tight, yielding warmth of her Flower Valley, enjoying the feeling of those slick, velvet muscles tightening around him in the wake of her orgasm.


 Only when Xenovia’s inner petals ceased their twitching did Aki flip her over.


 He guided her onto her hands and knees, her frame bent, displaying the full, pillowy curve of her hips.


 Behind those beautifully rounded contours, the girl’s flushed Flower Valley was clearly visible. Aki knelt behind her, tracing the elegant, delicate line of her waist before pressing the head of his Great Dragon against the slick, honey-coated entrance.


 The soft, peach-colored ring of flesh puckered and pulled at his touch; with the aid of Xenovia’s honeyed fluid, his Great Dragon glided inside with ease.


 ”Ah… again? It feels so good… so intense…” Xenovia groaned, her back swaying under his touch.


 After dozens of rhythmic thrusts, Xenovia, sprawled in a classic doggy-style position, began to sway her hips, actively pulling and grinding against the Great Dragon as its core.


 The two petals, parted wide by Aki’s member, wept beads of moisture, creating a wet, sticky suction with every movement.


 Aki surged in and out, his hands snaking around her waist—one hand pulling her closer, the other using his index and middle fingers to pinch and knead her slick, sensitive bud.


 This only drove Xenovia to bury her face into the mattress, her hips rocking with frantic, wild need.


 ”Ah… it feels so good… oh… don’t stop…” Xenovia cried out, her voice pitching higher as she gave in to the feeling.


 Aki’s fingers teased her sensitive flesh, while his Great Dragon hammered into the tight canal, the head striking the delicate entrance of her Flower Palace (Hanamiya) with every deep, heavy plunge.


 The sheer intensity forced Xenovia to mirror his rhythm, her hips bucking to meet each thrust.


 Aki gripped her slender waist, driving his Great Dragon deep until it pressed against her Flower Core, then withdrew just enough to plunge back in with renewed force, the head rotating to grind against the soft, yielding tissue.


 After a hundred such thrusts, Aki slumped forward onto her back, reaching under her arms to cup the heavy, trembling white globes of her breasts.


 He squeezed the soft, heavy flesh, using them as an anchor as he began to pump with blistering speed.


 His Great Dragon thrashed within her slick passage, the tip battering the neck of the Flower Palace (Hanamiya) with growing, relentless frequency.


 ”Ah… yes… yes… right there? Ah… so comfortable? Aki… you’re amazing? I’m going to lose it again? Ah… I can’t… I really can’t take anymore? Aki? Do it with me… give me your Essence… I want to carry your… child?” Xenovia pleaded, her words dissolving into broken, happy moans.


 On the edge of her third climax, Xenovia—her first time finally broken—could hold on no longer.


 Even with her abnormal stamina, she had been reduced to a puddle of lewdness, her Flower Core ravaged by Aki’s thick, sturdy Great Dragon, leaking countless trails of honeyed fluid.


 Under the desperate, rhythmic suction of Xenovia’s Flower Core, Aki’s Great Dragon pulsed with scorching heat, swelling even further as the head stretched the opening of the Palace and invaded the deep, warm sanctum of her Sacred Flower Palace.


 Added to by the involuntary tightening of her walls, Aki felt a jolt of pure, electric numbness at the tip, and under the burning stimulation of her Yin Essence, he lost all control, surging forward as he spent himself deep inside.


 As the hot, thick Life Essence struck the inner walls of the Flower Palace (Hanamiya), Xenovia shuddered violently, releasing wave after wave of warm Yin Essence that left even Aki’s limbs feeling liquid and drained.


 The string of successive orgasms breached the limits of her endurance. As their Dual Cultivation reached its peak, the overwhelming rush of pleasure sent her into a faint.


 Xenovia’s body went slack, and she collapsed, motionless, onto the bed.


 Aki slumped with her, remaining pressed against her smooth, soft back, his Great Dragon still buried deep within the warmth of her Flower Valley.


 He held her there, enjoying the warmth of her body, waiting for the wonderful, lingering afterglow to slowly fade.


 The bedroom fell into a sudden silence, save for the sound of their ragged, heavy breathing.


 Time passed in a blur. Just as Aki shifted, intending to withdraw, a hot, soft body pressed against his back.


 ”It seems I didn’t manage to conceive just now,” Irina whispered, her tone light and deceptively airy.


 ”To complete the mission, I have no choice but to… ah…”


 Before the Angel-Schoolgirl of the Church could finish, Aki took command. His Great Dragon, having already recovered its strength within Xenovia, slid along the length of her smooth, long legs, finding its way straight to the entrance of her Flower Valley.


 ”Ugh…” Xenovia let out, a soft, breathless sound of sudden, renewed stimulation.


 Following the girl’s short, sharp whimper, the child-bearing activities of the two Holy Sword-wielding Schoolgirls began once more.


 Outside the window, the autumn wind sighed and the tree branches swayed; inside, the air was heavy with the scent of musk and the sound of bodies entwined.


 That night, Maria and Lucia did not find Aki on the fourth floor.


* * *


 Time slipped away, and soon it was the end of September.


 Half a month had passed since the day they arrived and were thoroughly claimed by Aki.


 Irina and Xenovia had engaged in Dual Cultivation with Aki many times, yet the goal of conceiving a child remained elusive.


 Fortunately, they understood that bearing a child was a big task, and they had long since prepared themselves for a long, hard effort.


 Over this period, Aki had fully mastered the Angel Bloodline Talent he had newly acquired, as well as the Talent of the Perfect Holy Sword Wielder.


 In his current Combat Form, the twelve pairs of wings on his back—once a mix of Fallen Angel and Devil wings—had shifted into three distinct, intertwined pairs of wings.


 Compared to the Angel bloodline, the Talent of the Perfect Holy Sword Wielder was a much greater surprise to Aki.


 In this world, there were not only Holy Swords designed to combat Devils, but also those forged to slay the Dragon Race and other species.


 Aki clearly remembered that Michael possessed a dragon-slaying Holy Sword, one that inflicted devastating bonus damage against those with Dragon Race blood.


 Setting aside whether or not he could obtain powerful Holy Swords, with this Talent, if anyone ever attempted to wield such a blade against him, they would first have to ensure the weapon itself wouldn’t revolt.


 Holy Swords possessed a level of spirituality; compared to a master who was forced or coerced, a “Perfect Wielder” was exactly the kind of master they craved.


 When he first obtained the Perfect Holy Sword Wielder Talent, Aki sensed the presence of Durandal, which had been sealed by Xenovia in a different dimension.


 Unable to resist, he reached out and called it.


 Xenovia was startled, fearing that Durandal’s tyrant-like temperament was acting up again.


 ”Aki, wait! It’s dangerous!” Xenovia cried out, her instinct to intervene overriding her caution.


 She reached out, ready to grab the hilt and force it into submission before it could harm Aki.


 Instead, she watched in shock as the Holy Sword capable of cutting all things in the world—the sword known as the Tyrant—floated quietly in mid-air, allowing Aki to stroke its blade as if it were a pet.


 Faced with a stunned Xenovia, Aki offered no explanation, simply stating that it would no longer need to be sealed.


 Xenovia had been unable to fully master Durandal because her own strength was insufficient.


 Durandal, known as the Tyrant, was useless even with the bloodline of a perfect wielder; one required matching strength to command it.


 After several rounds of Dual Cultivation with Aki, Xenovia had ascended to S-Rank—a High-Class Devil—giving her enough power to finally wield it.


 With Aki by her side, there was no fear of Durandal becoming unruly.


 Likewise, with the aid of the Dual Cultivation Ability, Irina had become an S-Rank, six-winged Angel in one fell swoop.


 Not only had their strength grown rapidly, but the two girls had quickly adapted to their new lives.


 Xenovia was simple and straightforward; having become a member of Rias’s Peerage, she had fully integrated into the Occult Research Club.


 Irina, despite the natural holy aura of an Angel, spent so much time clinging to Aki, demanding to finish their “baby mission,” that she had no trouble fitting in with the others.


 After all, there was no better way to foster intimacy than by being honest and exposed in the same bed.


 As the days passed, the girls’ strength steadily improved. However, aside from refining his combat techniques and increasing his proficiency with his various Talents and skills, Aki saw no progress in his raw power.


 He even attempted to study the Martial Way, which he had been stuck on for a long time, hoping for a pleasant surprise.


 But the reality was that, much like the God-tier, he couldn’t even catch a glimpse of how the Martial Way might transform into an Immortal Path.

 Summary:

 Aki engages in an intense session of Dual Cultivation with Xenovia, which serves as a catalyst for their continued progression in strength. Following the climax of their physical intimacy and the inclusion of Irina, the narrative shifts to summarize their shared life and Aki’s mastery over his new Holy Sword and Angel bloodline talents. Xenovia and Irina both achieve S-Rank status, while Aki continues to search for a way to break through his plateau in the Martial Way.


 —


 Trivia:

 Xenovia’s ability to command Durandal was directly tied to her leveling up through Dual Cultivation with Aki.

 Aki’s combat form has evolved to feature three distinct pairs of wings, representing his merged bloodline traits.

 The Holy Sword Durandal possesses its own sentience and temperament, acting more like a subdued pet once Aki exerts his mastery.

 The concept of Dual Cultivation is established as a reliable method for the girls to gain power, even if the primary goal of conceiving a child remains unachieved.
