Sisters Donburi
From between her parted crimson lips leaked not a grotesque friction noise, but the thick, wet moan of a real woman. On her smooth, pale lower belly, the same pitch-black Mark of Subjugation that I'd mercilessly jammed into her soul core moments ago was burning horrifically, pulsing as if it were alive and breathing.
"S-Sister... Siiisteerrr!"
From behind, Rubia—who'd watched the whole thing—let out a beastly wail as she crawled through the ashes toward her. Faced with the sole blood relative who'd miraculously regained her human flesh, Rubia's eyes overflowed with hot tears blending ecstasy and guilt, cascading like a waterfall.
"Thank goodness... oh god, thank goodness... Seria, I'm sorry... I'm so, so sorry... sob...!"
Her heartbroken sobs sliced through the dank air of the mine, echoing off the walls.
Seria, sprawled naked at my feet and gasping raggedly, began to tremble unnaturally. The instant she'd reclaimed her human body and reason, the horrific memories of the agony she'd endured trapped in that spirit shell for so long crashed over her mind like a tidal wave. The searing pain of her soul being torn and burned, the bestial days lost to blind destructive instinct. And the architect of that entire hell—the perpetrator—was her own blood sister, sobbing right before her eyes. Those shattered recollections tore through Seria's head like shards of glass.
"Haa... haaaah...!!!!"
Seria clutched her head in agony, rolling across the floor. A flash of deep resentment and murderous intent toward her sister flickered in her eyes. The rage to rip apart the sibling who'd envied her nobility and turned her into a monstrous blaze wanted to erupt from her bloodshot gaze.
Seria's trembling hands reached threateningly for Rubia's throat. But just before her fingertips grazed that slender neck, they halted in midair, as if by some miracle.
"...Rubia."
The moment she uttered her long-forgotten true name and her sister's, cracks of devastation spread across Seria's fury-twisted face. Yes, her sister had made her a monster out of vile jealousy—but the woman now collapsed in utter despair at the bottom of hell was nothing more than her foolish, pitiable only kin.
In the end, instead of throttling her sister's neck, Seria's outstretched hands gently enveloped the shoulders of Rubia, who was prostrate and wailing on the ground.
"I'm sorry... I'm really sorry... waaah!"
Rubia burst into childlike sobs in her sister's embrace. As her sibling's hot tears touched her skin, Seria's own suppressed tears began to pour endlessly.
Anger and resentment crumbled helplessly before the thick bond of blood. Seria silently patted her beast-like wailing sister's back, covering that horrific sin and endless grudge completely with hot tears.
It was a tear-jerking, sublime moment of sisterly forgiveness and reconciliation blooming in the abyss of hell.
And I watched that nauseatingly touching reunion from a step back, my gaze cold and detached.
Seria silently patted her beast-like wailing sister's back, covering that horrific sin and endless grudge completely with hot tears. A tear-jerking, sublime moment of sisterly forgiveness and reconciliation blooming in the abyss of hell.
I watched that nauseatingly touching scene from a step back, then slowly opened my mouth to douse it in ice water.
"A beautiful reunion. But don't forget—this was all my doing. I peeled off that hellish shell and restored Seria to humanity. Now, time to repay that favor, right?"
The moment my voice rang out, Rubia—cradled in Seria's arms—snapped her head up. Her tear-streaked eyes burned with venomous hatred and rage toward me.
"You fucking beast... how dare you talk about favors? You raped me, defiled my soul, and now you want to turn my sister into your toy too? I'll kill you... I'll tear you apart with my own hands!"
Rubia spewed her insolent venom, poised to lunge at me. But I didn't even twitch an eyebrow as I approached her.
"Your mouth's been running foul for a while now."
I grabbed her by the hair and yanked her between my legs. Then I rammed my savagely engorged cock straight into her gaping mouth as she tried to curse me.
"Guhk, glurk...!"
Her eyes rolled back from the sudden invasion, harsh friction sounds leaking from her jaw-straining lips.
Seria, watching from the side, screamed and tried to rise and stop me.
"No! Please stop! Don't do that to Rubia...!"
But Seria's cry cut short. The Mark of Subjugation etched on her pale lower belly flared pitch-black, paralyzing her nervous system completely. She toppled rigidly to the floor, as if bound by invisible chains.
"Stay put, Seria. Repaying my favor is simple. Just comfort your sister nicely down there, like a good big sister."
At my command, her body jerked unnaturally, defying her will. Compelled by the mark's force, she shoved her head between Rubia's legs and extended her tongue to sloppily lick her sister's secret folds—while Rubia choked on my cock in agony.
"Ah... aaah...! No, why is my body... Rubia, I'm sorry... aaah!"
Tears of shame and despair streamed down Seria's face, but she greedily sucked at her sister's pussy, obeying the mark's command over her instincts.
Rubia's eyes lost focus as she was violated from above by me and below by her own sister.
I ravaged her narrow mouth like a beast. Each thrust deep into her throat made her body convulse, and I savored that thrilling resistance, pouring every drop of my pent-up lust down her esophagus.
"Gack, guh-hurk...!"
The instant Rubia choked down my hot semen, forcing it past her gagging—a searing pain like a red-hot poker stabbed her tongue tip, black light swirling around it. A new Mark of Subjugation etched on her tongue.
Moments later, as I pulled out, Rubia looked up at me with a dazed expression. The fierce killer intent from before was gone.
"Haa... haa... I'm sorry, Master. How dare I... be so rude to you."
From her lips flowed not insolent curses, but chillingly calm, perfect deference. She pressed her forehead to the ground, licking my instep while dutifully calling me "Master" with absolute submission.
Now everything was ready. I laid Seria—who'd been despairingly caressing Rubia—on the cold floor and said,
"Now, time to properly repay my favor."
"Haa... haa... I'm sorry, Master. How dare I... be so rude to you."
Seeing Rubia's obedient pose, forehead to the floor and licking my instep, I curled my lips in a cruel smile. The mark on her tongue had imprinted my will deep into her soul.
I turned to Seria, still writhing in self-loathing and despair.
"Now, time to properly repay my favor, Seria."
I shoved her shoulders roughly, pinning her to the cold mine floor. She gazed up at me with wet eyes, unable to resist.
I issued a new command to Rubia, prostrate beside us.
"Rubia, indulge all the spoiled affection you couldn't give your sister before. In your favorite way—real thick and deep."
At my order, shame flushed Rubia's pale face crimson. But the mark on her tongue glowed black, suppressing her reason.
"Ah... aaah... Understood, Master. As you command... I'll show Seria sister... my spoiling."
Trembling, Rubia rose and crawled atop the prone Seria. She spread her thighs wide, grinding her dripping intimacy right over her sister's face.
"Rubia... ah, no... please...!"
Seria whimpered, trying to turn away, but Rubia was relentless. She smeared her scent forcibly over Seria's face while greedily clutching and sucking her sister's voluptuous breasts.
"Aah, ah... Master... Seria sister's tits... so soft... haa, haa...!"
Rubia squeezed her eyes shut in ecstasy, biting and licking her sister's nipples like a starved beast.
Thick tears streamed from Seria's eyes at the sight. Her cherished little sister, now calling me Master and using her body as a tool to violate her—Seria's mind shattered to dust.
Savoring the wretched, lewd spectacle, I wedged between Seria's legs. I hoisted her slender thighs wide over my shoulders, locking them in place.
"Ah... Master, please... aaah!"
Seria's pleading scream cut off with my merciless thrust. I impaled her tight, slick depths to the hilt, branding my presence deep into her womb.
"Haak, aaah... aaaang!"
Assailed from above by her sister's hot tongue and body, and from below by my brutal cock, Seria's body arched like a bow.
"Ah, aaht! Haaaang! Hnng, mmph...! Ah, no... Rubia, aaah!"
Each time her blood sister suckled her breasts obsessively, Seria's noble reason splintered apart. The heavy sensation piercing her below, the clinging warmth of her sister above. That alien double assault tore beastly cries from her lips—no longer words.
I gripped Seria's waist tight and pistoned without mercy.
"Haak, haaht! Nng, slurp, chuup... Sister, siiiister...!"
Matching my rhythm, Rubia latched even harder onto Seria's chest. Her slutty tongue-work and saliva sounds echoed slickly through the cavern as Seria twisted and sobbed in the horrific vortex of pleasure.
"Haaaaak! Please, please stop...! Haaang, haaaang!"
The once-noble summoner sisters had fallen to slaves panting beneath me, devouring each other's bodies.
I reveled in the ultimate pleasure of perfect ownership, admiring Rubia's hair brushing my chest and Seria's wails from below.
"Chuuup, haa... hnnng! Aaaaang!"
Finally, Seria's eyes rolled white as her thighs quivered faintly. Her nipples hardened in her sister's mouth, her pussy swelling red with my thrusts. Each gush of love juices from that obscene union soaked the floor, their pride spilling out like waste.
It was the ugliest, most beautiful landscape of domination completed in this dark mine.
