Chapter 508 Demon King’s Efforts*
Edited by: Kanaa-senpai
While Aki was collecting payment from Serafall, Sirzechs and Odin’s allied faction leaders also learned about his safe return and the resolution of the situation.
Relieved, but also already dreading how to face Aki’s demands – especially Odin.
Loki was a major member of his faction. He’d caused this kind of incident multiple times. Not even handing over one Rossweisse, let alone sending a few more Valkyries, would make the matter simply go away.
Besides, he hadn’t even made his move on Rossweisse yet. Valkyries less attractive or powerful than her weren’t even worth mentioning.
The Angel and Fallen Angel factions were fine. They hadn’t interacted much with Aki. They’d mostly been along for the ride this time, but they still prepared gratitude gifts for Aki.
As for the other three Great Demon Kings, because Aki was close with the Devils, they weren’t too worried. They just silently waited for Aki to come find them.
But they were probably going to wait a long time. Aki’s payment collection from Serafall was far from over.
…
In the dim bedroom, the tawny fireplace light painted the two intertwined figures on the sofa.
Aki freely enjoyed the tender, seductive body beneath him. Using techniques he’d developed with Rias and the others, he moved both palms downward.
Maintaining his firm grip on Serafall’s silk-stockinged ass while gently parting the petals with his fingers, he slid his body’s softest, most flexible muscle into the already-defenseless dark spring.
”Don’t… lick so deep… ngh… stop…”
The instant his soft, slippery tongue entered, unfamiliar fear drove Serafall to struggle slightly.
When Aki, at a speed she couldn’t adapt to, went straight to a sensitive spot deep in her flower path, the girl’s delicate body was pinned to Aki’s, leaving only involuntary trembling in her limbs.
Her brain felt fuzzy… so strange… a tongue… was this really that comfortable…
Not the rough intrusion she’d imagined. The tongue’s movements inside her flower path were far gentler than Little Aki (Aki’s member), with the flexibility that a mass of muscles couldn’t match.
Serafall had only occasionally rubbed her clitoris and petals herself. She’d never experienced a nimble rotation inside her flower path.
Like a loving caress, the warm flow rapidly melted her fear, permanently etching a new preference in the girl’s heart.
”A little… slower, aah… I like it… the bean, I want that too… nngh?…”
Her eyes unfocused, she half-listed her sweet breath, reaching one hand behind her to free Aki’s finger.
He went along with it, lightly sweeping that already-swollen, hard red bean with his fingertip. Every touch pressed an on switch for arousal, instantly drawing a large amount of honeyed fluid from her.
Aki rolled his tongue, swallowing all of Serafall’s wet joy into his throat.
But this irregular, on-again-off-again teasing threw Serafall into complete confusion.
Her eyes misty, she cradled the scorching Little Aki (Aki’s member) in her palms, pressing her flushed face against the pulsing, veined shaft, licking the柱身 (column body) with her wet little tongue. She moaned incoherently.
”Ahh… don’t… stop teasing me… it’s maddening… w-waah…”
Aki usually respected girls’ wishes. But not now.
Completely dominated by the desire to ravage the woman beneath him – an urge written into his very DNA – he knew that simply pressing her clitoris with his fingertip, paired with regular circular motions, could easily send this girl into ecstasy.
But the more Serafall begged with a trembling, tearful sob, the less he wanted her to reach satisfaction.
The layered folds of flesh squeezed his tongue hard, as if they would envelop and swallow it whole if he stopped.
This flesh sensation, completely different from French kissing, also intoxicated him. His nimble tongue tip, like a little fish, swam nimbly through the narrow, untested passage.
The comfortable, licking sensation from below and this rare, soft female voice heightened his excitement. He reached down, tearing the hole in her silk-stocking-wrapped ass wider.
A third of her buttocks were fully exposed. The white, delicate cheeks flushed with arousal were slightly spread by his two hands. Her cute, pink rosebud trembled adorably under Aki’s gaze.
He temporarily withdrew from the tight flower path, letting his tired tongue muscles rest briefly. Aki examined Serafall’s pink daisy, suddenly very interested.
Serafall was already a God-Class powerhouse. She almost certainly didn’t need to regularly代谢 (metabolize). Even without pre-cleaning, this place of such importance and intimacy should have been clean anyway.
”Rather than the little bean, I think Serafall wants this here more. So twitchy… it’s adorable…”
”Aah, no, I can’t… ngh… ooh… it’s dirty… ngh aah… uu?…”
Realizing if she continued speaking, her tone would only grow more indecent, Serafall gave up trying to articulate her shame. She逃避 (avoided) it by devotedly licking the hot, hard Little Aki (Aki’s member).
Besides the shame, there was another reason her objection wasn’t valid.
Just as Aki thought – all women love cleanliness. As long as they can, no woman lets even a hint of dirt touch her body.
So, since becoming a God-Class powerhouse, Serafall had never once used her pink daisy. She’d truly lived by the creed that cute magical girls don’t do their business.
Unable to deny the pleasure Aki’s tongue technique brought, Serafall’s mind was already too broken to keep thinking.
Aki firmly held the girl’s perky ass, greedily dragging his tongue back and forth between her petals and daisy. An occasional light nibble from his teeth stung her lower body, but it only enriched the layers of pleasure, offering a different kind of刺激 (stimulus).
Before long, Aki made up his mind. His right hand’s two fingers satisfied Serafall’s wet little garden, while his tongue focused on attacking the narrow daisy.
This payment, he was going to open all three of Serafall’s holes at once!
Starting with exploratory rotations around the outside, he induced Serafall’s daisy to slightly part.
Then his tongue, curved into a U-shape, advanced millimeter by millimeter into Serafall’s pink daisy. Every time he heard a pained moan from her, he pulled back to the starting point.
After several repetitions, the girl’s rosebud had been trained into an兴奋的 (excited) diameter, happily twitching under the stimulation of Aki’s tongue.
Coordinated with the finger vigorously digging into her front hole’s tender flesh, Serafall’s body gradually lost control. Her long-dazed eyes rolled upward in pleasure. Her gushing desire was like a boulder suspended from the ceiling of her mind, tied by her hair. It grew heavier with each strained moan.
”Ahh… I’m, I’m going to… it’s weird… nnng…”
As if something inside her snapped, Serafall squeezed her eyes shut. Her face rubbed against the hot Little Aki (Aki’s member). She released suppressed gasps.

Summary:
Aki and Serafall’s intimate session continues in her bedroom. Aki uses his tongue skillfully to overwhelm Serafall’s senses, and – realizing her God-Class body keeps her perfectly clean – decides to open all three of her holes at once. He works his tongue into her daisy while his fingers ravage her front cave, bringing her to the brink of uncontrollable climax.

Notes:
• Serafall – Serafall Leviathan is a Super-Devil, one of the Four Great Satans, and Sona Sitri’s bubbly, energetic sister with an extreme sister-complex. A peer to Sirzechs who once vied with Grayfia for the title of the Underworld’s strongest female devil, she balances her immense power and threat-monitoring duties as a leader with a personal preference to avoid conflict.
• Sirzechs – Sirzechs Gremory, the red-haired Demon King Lucifer, is a formidable strategist and Rias’s brother. Known for his battlefield prowess, he charmed the enemy general Grayfia into defecting, later marrying her and fathering Georgix. A complex, often elusive leader, he balances diplomatic duties and rebuilding the Underworld with a cultivation obsession that frequently strains his family life, yet he remains an ally to Aki.
• Aki – A tall, handsome Kuoh Academy student and Red Dragon Emperor, he is a reincarnated cultivator who currently inhabits a pitch-black cat form with piercing azure eyes. Calculating and protective, he commands the Boosted Gear and Origin Blood. Connected to the Gremory household and Naruse Mio via a Soul Network, he manages a vast harem while navigating ancient conspiracies and his own feline instincts.
• Rias – Rias Gremory, a sharp, playful high-class devil and Gremory heiress, is Sirzechs’s sister and daughter of Venelana. Known for her crimson hair, she heads the Occult Research Club, protecting her peerage including Mio, Xenovia, and Maria. As Aki’s fiancée and partner privy to his transmigration, she guides his cultivation while navigating complex feelings toward his pursuit of Grayfia and her mother.
• Venelana – Venelana Gremory, the elegant, silver-haired matriarch of House Gremory and former Bael noble, is a refined beauty known for her powerful bloodline. Wife to Georg and mother to Rias and Sirzechs, she is often compared to figures like Shela and Greyfia. Despite her poised exterior and complex family status, she is currently involved in a secret affair with Aki, a reality likely known to Rias.
• Greyfia – As the Gremory household’s silver-haired Head Maid and Sirzechs’ devoted wife, she is a reserved beauty who balances domestic duties with her formidable Lucifugus bloodline and space mastery. Once an enemy general charmed into defection by Sirzechs, she is now his loyal partner and Venelana’s daughter-in-law. Beyond her marriage, she shares a deep, personal connection as the lover of Aki.
