The quiet hum of the Underworld's libraries carried a peculiar kind of weight, ancient, suffocating, and filled with secrets that even the devils feared to remember. Deep beneath the Gremory estate, within a sealed section of the Grand Archive, a lone figure moved between shelves lined with dust and forgotten scriptures. Her silver hair glimmered faintly under the dim blue torches that burned with eternal mana.
Morgan's expression was calm, but her eyes were sharp, scanning each title with deliberate precision.
After her recent investigations across the Underworld, whispers of the Old Satan Faction had led her here. Their movements were all over the place. She managed to trailed some of them and heard of their whisperings, yet none of it seemed aimed directly at the current Satans. Instead, their activities circled something else, something far older.
She had followed the traces of a familiar corrupted mana to a ruin hidden in the shadowed canyons of old Lucifaad territory. What she found there disturbed even her. A faint pulse of divinity: not demonic, not angelic, but something beyond both. A fragment of power that resonated eerily similar to the same energy Morgan had senses from the Demon God itself.
That was why she now stood here, in the restricted archives once belonging to the original Satans.
Her fingers brushed along the spine of an ancient tome bound in black leather, marked with seals that should've deterred anyone else. Yet the wards flickered and parted like silk as she whispered a few foreign words, the language of her own world.
The book trembled before unfolding on its own, releasing a faint crimson mist that smelled of old blood and ash. The title on the first page read:
"The Great War and the Sealing of the Beast of Apocalypse."
Morgan's lips curved slightly. "Beast of Apocalypse… 666, or as they called now, Trihexa, was it?"
She began to read. The script detailed the aftermath of the Great War, the sudden appearance of Trihexa, and how the exhausted Biblical God managed to seal the creature at the cost of His life. But what caught her attention was the origin section. The scholars who wrote it couldn't agree whether Trihexa was created, summoned, or born.
Some believed it was a divine punishment from God. Others claimed it was the embodiment of chaos that predated all existence and had existed since the beginning of time. Yet some maniac guessed it came from the sea of stars.
"But for there to be a trace of Demon God in this world, my dear husband wouldn't like it~" Morgan murmured with a playful smile before her expression turned serious once again.
What does Demon God and Trihexa has in common? The former has some semblance of sanity but rare, most of the time they only sought destruction. Judging from the book, Trihexa could be a force of destruction, harbouring absolute malice to all living things.
"Hm~ I'm feeling a little temptation to check the sealing location, I might finds something interesting there~" Morgan pondered out loud. No one knows exactly where Trihexa was sealed by the Biblical God, but it is certain somewhere in the Underworld.
With a wave of her hand, a fog rise from the ground and gathered in front of her. In the blink of an eye, it turned into a mirror. Within it showed a bird eye view of a guest room from the window—her spell connected her to her familiar Crow she left to watch Kousuke. It seems her husband is having some deep intimacy with Akeno after they got back from their date.
On a second thought, she considered joining in on the fun but shook her head at the end.
"I'm sure my husband will spoiled me plenty once I gathered all these intel for him~" she muttered before using telekinesis to move the book back to its original spot. She didn't forget to wipe out all of her traces, and even leave behind a small amount of demonic energy to completely masked off any remaining traces. Then her figure slowly vanished like chalk being erased from the blackboard.

[Smut incoming, you have been warned.]
Kousuke POV
Gremory Mansion, Guest Room.
After our date in the Underworld, we made our way back to Gremory Mansion, the sexual tension between us palpable. As soon as the guest room door clicked shut and locked behind us, Akeno couldn't contain herself any longer. She reached up, wrapping her slender fingers around the back of my neck, and pulled me into a fierce, passionate kiss. I responded eagerly, my calloused hands gripping her plush, rounded ass, kneading the supple flesh like dough.
Akeno shivered in anticipation as she felt your hands groping her plump rear, a soft moan escaping her lips despite herself. She bit her lower lip, trying to stifle any further sounds of pleasure, and leaned in closer to me, her violet eyes sparkling with mischief and desire.
Breaking the intense liplock, I flashed Akeno a wicked smirk, my brown eyes glinting with lust and mischief. "Better keep your voice down, baby. Wouldn't want to alert Rias or that pervert Issei to our... activities, now would we?" I teased, giving her delectable rear another firm squeeze before continuing. "I kind of missed your sloppy toppy~"
At the mention of her oral skills, Akeno smirked, trailing a finger down my chest. "Mmm, you mean like this?~" She sank gracefully to her knees before me, maintaining eye contact as she slowly, teasingly unzipped the fly. She licked her lips as my cock sprang free, already rock hard and throbbing with need.
Akeno wrapped her slender fingers around my thick shaft, stroking it slowly as she gazed up at me with a wicked grin. "I've been craving the taste of you since our last intimacy, Kousuke~" she purred before leaning in and dragging her tongue along the underside of my cock, from base to tip. She swirled her tongue around the swollen head, lapping at the bead of pre-cum already leaking from the slit.
Then, without warning, she took it into her warm, wet mouth, her plump lips stretching obscenely around my considerable girth as she began to bob her head, sucking with enthusiastic fervor. "Mmph...~" Akeno moaned around my cock, the vibrations sending jolts of pleasure shooting up my spine.
"Ooh yeah, that's it," I groaned when Akeno begins bopping her head off my cock eagerly while keeping her lust drunken eyes looking up at me. The arousing sight was making my head dizzy from all the pleasure.
Akeno continued her enthusiastic suckling, taking more of my impressive length into her hot mouth with each bob of her head. Her tongue swirled and danced along the throbbing shaft, teasing the sensitive underside. She could feel it pulsing against her tongue, growing even harder.
She released my cock from her mouth with a lewd pop, a string of saliva briefly connecting her lips to the engorged head. "You taste even better than I remembered~" Akeno praised huskily, gazing up at me with lust-drunk eyes. Her cheeks were flushed a pretty pink, and her chest heaved with each excited breath.
Then Akeno wrapped her lips around the tip of my cock once more and began to suck harder, hollowing her cheeks as she took it deeper. One hand pumped the base of my shaft while the other gently massaged the heavy balls. Her deft fingers and skilled mouth worked in tandem, bringing me closer and closer to the edge.
Akeno could feel my hips starting to twitch, my body instinctively craving more of her touch. She knew I'm getting close. Determined to make this a unforgettable experience for me, she doubled her efforts, sucking with wild abandon as lewd slurping and suckling noises filled the room.
"Shit fuck!" I grunted, fisting my hand in Akeno's silky hair as I started to roughly thrust my hips, fucking her pretty face with abandon. "Gonna... fucking... cum!"
With a guttural moan, I buried myself balls-deep in Akeno's hot, willing throat and unleashed a torrent of thick, potent seed directly into her stomach. Rope after rope of my heavy load pumped into her as my cock throbbed and jerked against her tongue.
"F-Fuck yes! Take it all baby!" I growled through clenched teeth, holding her head in place as I emptied my aching balls deep in her gullet. Akeno moaned in delight around my twitching length. She eagerly gulped down each thick rope of my cum, relishing the taste and texture on her tongue. Her throat worked diligently to swallow every drop I had to offer.
As my intense orgasm began to subside, Akeno slowly released my softening cock from her mouth with a lewd pop. She sat back on her heels, gazing up at me with a satisfied, if slightly dazed, smile. A few stray drops of my cum clung to her plump lips, and her chin glistened with the mixture of her saliva and my release.
Akeno licked her lips, savoring the lingering taste of me. "Mmm, you taste absolutely amazing, Kousuke~ it's making me addicted to it," she praised softly, her voice slightly hoarse from the enthusiastic oral worship she had just bestowed upon me.
"Then you should be happy because I'm not done with you yet," I said with a smug grin, my eyes glinting with lust and desire as I watched my softening cock returns to the original hardness and throb against Akeno's flushed cheek. "Come on, let's get you sprawled out on that bed. I know your needy little cunt is absolutely aching to be filled and stretched by my big, throbbing dick~"
Akeno's eyes gleamed with excitement and anticipation at my words, a shiver of desire running through her body. She could feel my cock, stiff and throbbing against her cheek, and it made her ache with a primal, all-consuming need.
Obediently, Akeno crawled onto the bed, her hips swaying enticingly. She positioned herself in the center of the mattress, on her hands and knees. Looking back over her shoulder at me, she slowly lifted her skirt, revealing the tantalizing curve of her ass and the lacy edge of her panties.
With a coy smile, Akeno reached back and slowly slid her panties down her long, shapely legs. She kicked them off to the side, leaving herself bare and exposed to my hungry gaze. Between her thighs, I could see the glistening pink folds of her sex, already slick with arousal.
Akeno arched her back, pushing her hips up and out, as if presenting her needy cunt to me like an offering. She looked at me from beneath lowered lashes, her violet eyes smoldering with lust and desire.
"Is this what you wanted to see, Kousuke?~" Akeno purred, reaching back to hold herself open for me. "My greedy little pussy is already so wet and ready for your big, hard cock. I need you to fill me, stretch me, fuck me until I can't think of anything but the feeling of your dick buried deep inside me~! Please Kousuke, I'm aching for you to take me, to claim me, to make me yours once more!~"
I couldn't hold back any longer, my rock hard cock throbbing with the desperate need to be buried inside Akeno's dripping pussy. Positioning myself at her entrance, I rubbed the swollen head of my dick teasingly against her slick folds, feeling them part slightly around my tip.
"Fuck, you're absolutely drenched, baby," I muttered, my voice low and rough with arousal. I reached forward and gripped her plush tits firmly, sinking my fingers into the soft, supple flesh as I slammed my hips forward. My cock speared into Akeno's tight, wet heat, stretching her open and filling her completely in one powerful thrust.
"Aah!"
Akeno let out a sharp gasp, back arching as she felt my hard, throbbing cock penetrate her dripping sex. Her slick walls stretched around my girth, accommodating my impressive size as I buried myself to the hilt inside her.
She could feel every ridge and vein of my shaft rubbing against her sensitive folds, setting her nerves ablaze with pleasure. Akeno moaned wantonly as I began to move, my hips slamming against her plush ass with each powerful thrust.
"Y-Yes! Oh god, yes!~" she cried out, her voice pitching with each forceful drive of my cock into her aching core. "Harder, Kousuke! Fuck me harder! Ah... your cock feels so big, so deep inside me!~"
She met each of my thrusts eagerly, pushing her hips back to take me even deeper. The obscene sound of skin slapping against skin and Akeno's escalating moans of rapture filled the room, a symphony of unbridled lust and carnal passion.
I leaned in close, my breath hot against Akeno's ear as I panted with exertion, my voice a low, husky growl. "Fuck, listen to you moan like the sexy little cock slut you are, Akeno~" I rasped, punctuating my words with a sharp thrust that made her cry out. "You sound so fucking hot when you're losing yourself on my dick like this."
I could feel her silken walls starting to flutter and clench around my shaft, her impending orgasm building like a tidal wave. I gripped her hips tighter, fingers digging into the soft flesh as I rutted into her harder, chasing my own rapidly approaching climax.
"That's it baby, let it happen," I urged, my voice strained but encouraging. "I want the whole fucking mansion to hear you screaming on my cock. Let them know who this hot little cunt belongs to, who's claiming you so thoroughly~"
Akeno threw her head back with a throaty, wanton moan as her orgasm crashed over her, waves of intense pleasure radiating out from where my cock was buried deep inside her convulsing pussy.
"A-Ahhhnnn!~ Y-Yes, I'm cumming! I'm cumming on your magnificent cock!~" she screamed, no longer bothering to hold back, wanting the whole mansion to hear her ecstasy. "Don't stop, fuck me through it! Fill me with your hot seed, please! I want to feel your cum flooding my womb!~"
Her velvet walls clamped down like a vice, rippling and squeezing my pistoning shaft. Akeno's voluptuous body trembled and shook with the force of her climax, her skin glistening with a sheen of sweat. Her tits bounced wildly in my grip as I continued my relentless thrusts, pushing her to new heights of pleasure.
"Fuck, take it all Akeno! I'm gonna pump you full, fuck!" I grunted, my voice strained with pleasure as I slammed my hips forward one last time, burying my throbbing cock as deep as it would go into her spasming cunt.
My body shuddered as I began to erupt, my heavy balls churning and releasing a massive, scorching hot load directly into Akeno's hungry womb. She let out a scream of pure, unadulterated ecstasy as she felt my seed erupting deep inside her, painting her insides with my sticky essence. Her eyes rolled back, tongue lolling out as her body shuddered violently, overwhelmed by the sensation of my massive load flooding her hungry cunt.
"YES, YES,YESSSSS!~" she howled, her voice hoarse from screaming my name. "Fill me, fill me, fill me! I can feel it, so much hot cum pumping into my pussy! Ahhh, it's so warm, so thick!~"
Completely spent, Akeno collapsed face-first onto the bed, her voluptuous ass still raised as my softening cock remained buried inside her cum-flooded cunt. Her skin was flushed, her hair a wild mess, and her body glistened with the sheen of her exertion. She looked utterly debauched, thoroughly used and satisfied in the most carnal way possible.
Gasping for breath, Akeno looked back at me with glazed, lust-drunk eyes. "That was... incredible, Kousuke~" she praised breathlessly.
