Asmodeus System: Stealing My Bully's Mother

​Inside the Exclusive VIP Rest Room, heavy silk curtains completely blocked out the late afternoon sun.

​Ethan Valen lounged comfortably on a black leather sofa. One hand lazily swirled a glass of red wine. Spread across the mahogany table before him were internal academy documents and border maps of the Rosenberg Faction—intelligence tributes from Isolde.

​Knock. Knock.

​A soft rap on the door broke the silence. Without waiting for an answer, the handle turned from the outside.

​Kaelia von Ashford stepped inside.

​The Student Council President wore her grand uniform, immaculately ironed. The gold thread stitching on her sleeves pulsed with faint, disguised mana. Outside this door, thousands of students and instructors still worshipped her as the untouchable Fire Queen. The greatest genius of their generation.

​But the moment the heavy wooden door clicked shut and automatically locked, Kaelia’s arrogant aura evaporated. Crumbled into nothingness.

​Rustle...

​Unprompted, Kaelia walked forward. Her knees, clad in tight black stockings, hit the plush carpet right at Ethan’s feet.

​The red-haired girl bowed her head, exposing her smooth, slender neck in absolute submission.

​"Kaelia reporting... My Master," she whispered. Her voice was soft, laced with a subservience that had been brutally drilled into her the night before.

​Ethan set his wine glass down. He looked at the girl kneeling beneath him with a cold smile. "What are the updates from the capital?"

​"The messenger owl returned this afternoon," Kaelia answered, not daring to look up. "Father... I mean, Duke Ashford, has accepted Madam Isolde’s forged report. He believes you merely experienced a delayed mana awakening triggered by a reaction to the heirloom ring."

​Kaelia pressed her hands together on Ethan’s thighs, continuing her report with a tone of genuine relief. "Father has ordered all of his shadow knights to withdraw from the academy’s borders. He will not suspect you anymore, My Master."

​"A wise choice for a Duke," Ethan murmured.

​He reached out, grabbing Kaelia’s chin and forcing her to look up. The girl’s golden eyes appeared slightly hazy, refracting a faint crimson glow in her pupils—undeniable proof that the Sin Mana had seeped deep into the roots of her soul.

​"How is your fire element?" Ethan asked.

​In response, Kaelia raised her right palm.

​Whoosh. A small spark of fire danced atop her finger. However, the flame was no longer its majestic, golden-yellow hue. It was now a deep, thick red, just like pure blood. It radiated a heat that was incredibly savage, destructive, and intoxicating.

​"This fire... is far stronger than before," Kaelia whispered. She stared at the blood-fire in her hand with a mix of awe and horror. "It can pierce through standard mana shields with ease. But every time I summon it... my body feels so hot, My Master. My lower stomach... flutters, calling out for you."

​The black fire-rose tattoo hidden beneath Kaelia’s uniform—right above her womb—pulsed warmly in resonance with the glow of the blood-fire.

​Ethan smirked. His thumb brushed against Kaelia’s trembling lips. "That is my stamp of ownership, Kaelia. The stronger your fire becomes, the tighter your soul is bound to me."

​"Y-yes... My Master..." Kaelia replied weakly. She leaned her cheek into Ethan’s palm, surrendering whatever remained of her ego and pride without a trace.

​Ethan patted her cheek gently. "Your new task is simple. Use your influence as the Council President to monitor the movements of Duke Alaric’s shadow knights deployed around the academy. Report every single breath they take to me."

​"I understand, My Master. Your command is my absolute law," Kaelia promised firmly.

​As Kaelia stood up to adjust her uniform and return to her duties, the Asmodeus System interface suddenly exploded across Ethan’s retinas.

​[ACHIEVEMENT UNLOCKED: DUAL TARGET SUBMISSION (100% SYNCHRONIZATION)]

Target 1: Isolde von Rosenberg (Archmage / Absolute Subjugation)

Target 2: Kaelia von Ashford (High Mage / Absolute Subjugation)

​[EXTRACTING SUBJUGATION REWARDS]

[New Active Skill Unlocked: Sin Concealment (Rank C)]

Function: Allows the Host to completely erase their mana signature, heartbeat, and physical presence from enemy perception up to Rank S (Master Knight/Sovereign Mage) for 30 minutes.

​Ethan’s eyes gleamed as he read the description of the new skill. An incredibly dark, demonic smirk formed on his face.

​"Perfect," Ethan whispered. This skill was the final puzzle piece he needed to execute tonight’s madness.

​That night, pitch-black darkness blanketed the West Wing of Zenithar Academy.

​The Rosenberg Residence—a grand Gothic-style building constructed specifically for the Duke’s family—stood imposingly amidst an expanse of artificial snow gardens.

​Inside the residence, the tension was suffocating. Dozens of heavily armored knights guarded every corner of the corridors. An extremely freezing aura radiated from the master bedroom on the second floor. That was where Duke Alaric von Rosenberg was meditating, repairing Kurt’s scorched mana circuit.

​However, amidst the ultra-tight security of a Master Knight (Rank S), a shadow slipped through the outer magical barrier like a ghost.

​Ethan Valen stepped lightly onto the roof of the residence.

​[Sin Concealment: Activated]

​An incredibly thin yet absolute aura of Sin Mana wrapped around Ethan’s entire body, rendering his presence as transparent as empty air. Magical sensors, mana bloodhounds, and even Duke Alaric’s sensory perception domain were completely blind to his movements.

​Ethan dropped silently onto the second-floor balcony. He opened the glass door to Isolde’s private office, which the Duchess had deliberately left unlocked from the inside.

​Click. The glass door sealed shut once more.

​The office was dimly lit, illuminated only by the faint glow of a rose-oil candle. Isolde’s expensive perfume mingled with the familiar scent of Sin Mana.

​In the center of the room, Isolde von Rosenberg stood frozen.

​The woman wore a black silk nightgown that was obscenely sheer, exposing her slender neck and fully mature curves. The Duchess’s face was deathly pale. Her breathing was ragged, and her hands wrung together in absolute desperation.

​What made the situation a thousand times more nerve-wracking was... the double doors in the corner of the room.

​Those ebony connecting doors led directly into the adjacent room. The exact room where her husband, Duke Alaric, was currently meditating!

​"M-My Master... you are truly insane..." Isolde whispered hoarsely. Her voice trembled violently as Ethan literally stepped out from the shadows of the balcony.

​Isolde crawled forward in a panic. She fell to her knees in front of Ethan, clutching the fabric of his trousers.

​"Alaric is in the next room... His aura is blanketing this entire building! If he senses even the sliiightest fluctuation of mana, he will behead us both in the blink of an eye!"

​Amazingly, even as her words voiced mortal terror, Isolde’s icy blue eyes showed absolutely no sign of rejection.

​On the contrary, the Incubus Mark and the black rose tattoo sprawling across her back pulsed wildly.

​The lethal danger of being caught by her own husband—combined with her absolute submission to Ethan—was shocking the Duchess’s physical nerves with the most insane wave of sexual stimulation of her entire life.

​Ethan looked down. He grabbed Isolde by her platinum hair and forced her face up to meet his gaze.

​"Hmm? What’s wrong, Isolde? Are you afraid your husband might hear?" Ethan whispered. His voice was incredibly soft, ghosting over Isolde’s lips.

​"I-I am afraid... but... but my body..." Isolde bit her lip hard. Tears of forbidden arousal leaked from the corners of her eyes. "My body only craves yours, My Master... P-please... just don’t let him find out..."

​"Then keep your mouth tightly shut," Ethan hissed ruthlessly.

​He hauled Isolde to her feet. He roughly spun her around and pressed her firmly against the ebony door—the very door separating them from Alaric’s room.

​Thump!

​Isolde’s bare back flattened against the cold wood. She could feel the faint vibrations of her husband’s Master Knight Aura thrumming right through the timber.

​Alaric was less than three meters away from her!

​Giving Isolde’s sanity no quarter, Ethan lifted her black silk gown and launched his absolute magical invasion from behind.

​"NGHHH---!"

​An ear-shattering scream nearly erupted from Isolde’s throat.

​The Duchess hurriedly clamped both hands over her own mouth. She bit down on her fingers until they bled just to choke back the moan that would invite certain death.

​Isolde’s eyes blew wide open. Tears streamed down her cheeks as Ethan moved with a savage, dominating rhythm from behind.

​Every thrust made the ebony door she was pressed against rattle faintly.

​Thud... thud... thud...

​From behind that door, Duke Alaric’s baritone voice could be heard murmuring softly. The man was chanting a high-tier healing spell for Kurt.

​The Duke—an S-Rank warrior feared across the kingdom—was completely blind. He was entirely unaware that right behind his office door, his prized wife was being thoroughly ravaged by the low-caste boy he desperately wanted to kill.

​"Can you feel him, Isolde?" Ethan whispered, his breath piercing right through the Duchess’s ear. His hands gripped her slender waist ferociously.

​"Your husband is right behind this door. One moan... and both our heads will roll. So hold it in... my servant."

​"Mmphhh! Mmmmphhh...!"

​Isolde shook her head crazily. Her eyes rolled back. Tears, sweat, and blood from the bites on her fingers mixed together.

​The horrific sensation of instant death collided with the euphoria of Sin Mana flooding her circuit. The combination detonated into a peak of ecstasy that shattered Isolde’s entire soul and sanity.

​The black rose tattoo on her flawless back glowed brightly in the darkness, greedily absorbing every drop of dark energy Ethan poured into her womb.

​The forbidden union inside the enemy’s den raged intensely, accompanied by the rhythm of her husband’s spell incantations from the next room over.

​Nearing midnight, Ethan finally pulled back.

​Isolde slumped limply onto the wooden floor like a puppet with its strings cut. Her silk gown was in tatters. She panted soundlessly, her chest heaving wildly. Her eyes radiated a submission that could never be cured. She was now absolutely Ethan’s property—body, mind, and soul.

​Ethan calmly adjusted his clothes, looking down at the woman sprawled at the tips of his boots.

​At that very moment, a barrage of crimson-red notifications violently pulsed across Ethan’s retinas with blinding intensity.

​[FORBIDDEN SUBJUGATION IN ENEMY TERRITORY (PERFECT EXECUTION)]

Location: Rosenberg Residence (Primary Target’s Private Quarters)

Condition: Subjugation performed undetected by Rank S Target (Duke Alaric von Rosenberg).

​[SYSTEM MECHANISM TRIGGERED: PASSIVE MANA DRAINAGE]

Explanation: By uniting with Isolde (who is fully contaminated) precisely at the epicenter of a Rank S Aura source, the Host’s Sin Mana successfully hijacked and passively siphoned Duke Alaric’s ambient energy flow.

Result: Bypassing the Host’s Normal Mana Circuit Limitations.

Sin Mana Capacity Upgraded: Rank C ➔ Rank B (Silver / High Mage Level)!

​BZZZZT!

​A wave of black-gold energy silently detonated within Ethan’s heart.

​His mana circuit tore past its old limits, expanding to become three times wider and denser. Ethan took a deep breath, stifling a groan as the pure power of Rank B now burned in his veins.

​He didn’t even have to fight Duke Alaric physically!

​Simply by sneaking close and exploiting his wife, Ethan had forcibly siphoned the Duke’s power to boost his own rank!

​Ethan leaned down, placing a quick kiss on Isolde’s still-trembling, weak lips.

​"Good work, my servant," Ethan whispered.

​Isolde smiled hazily. She closed her eyes in absolute obedience. "Thank you... My Master..."

​Ethan turned around, walking toward the glass balcony door. His shadow melted and vanished into the pitch-black night, leaving not a single trace behind.

​In the next room.

​Duke Alaric von Rosenberg opened his eyes from his meditation.

​The giant of a man furrowed his brow deeply. He felt a bizarre, slight depletion in his aura reserves.

​However, the Master Knight merely shook his head roughly, assuming it was the result of fatigue from chanting healing spells for hours on end.

​He was completely unaware... that his throne, his power, and the wife he prided himself on the most, were being hollowed out from the inside until nothing was left.
