"…to bear witness to my beauty and power!" The demoness's powerful voice shook the foundations of the church as she spoke. "You have served your purpose. Far better than I ever could've imagined. So your queen is offering you this small mercy."
She twisted her obscenely thick neck as she lowered her gaze further down Jim's naked body. The veins pressing against her skin strained and pulsed with a dark, viscous liquid. Something akin to mock pity played across the sculpted cruelty adorning her beastly expression. "Mmmhm, such a pathetic cock. Yet still hard," she pressed her foot against his crotch, pinning him to the ground by sheer force. Jim futilely tried to struggle as a pair of her toes encircled his erect and glistening glans. Feeling his shaft twitch, Mariana put his cock in a stranglehold, clenching shut his urethral passage, enjoying his frustrated thrashing. "Don't dare spill your seed on me, or else I'll use your tongue to clean me until the only taste you can remember is of my... ughhhnaahaa.. muscles."
Mariana closed her eyes as a blissful shudder arched across her spine. Her back and neck muscles bulged as she threw out her arms. The demoness savored the control she had over her coiling and tri- and biceps that had burst past human limits into monstrous proportions; the clarity it brought to feel the corded sinew to contract and ripple with power! She closed her clawed hands into fists. To think she had feared the Corruptor's gifts or were satisfied with leaving it in Jim's hands. Sending man after man, when she should've always claimed it for herself. She drove her foot further into the cracking floor, for a second toying with the thought of breaking her unwitting errand boy under her heel. He should be praising her for using even a sliver of her strength to end his wretched existence.
The demoness eased the pressure on Jim, too busy marveling at the deep valleys and hills formed by her bulbous ligament as she flexed. She traced the outlines with a clawed finger. They were wound up so..., her muscles exploded with a layer of new growth as she tightened them further! "Yesss! So much power!" The hulking fiend's cavernous voice broke as the pleasure spilled hotly from her core as a jet of squirting juices from her clenched and swollen pussy. The dripping essence of corruption flowed and gathered in a glossy black puddle, reminiscent of the one Jim had found in the room of bones. Her tail crushed the furniture of the cramped space wherever she swept it, leaving more of the church in ruins. The bed was unrecognizable, broken into a thousand splinters.
Despite the promise to spare him, the demonic brute seemed lost in the continued ecstasy caused by the senseless acts of destruction and almost caught Jim up in it as he scrambled for safety. She'd break the world before ascending a mountain of ruined skyscrapers to take her throne as its rightful ruler!
"Something more is...," Her massive clit throbbed as it endured the assault coming from her fingers. A mounting pressure that continued to build and ached for release, "UHHNNrrhhAAAGHH!" Spreading apart her labia, she pushed several of her fingers inside the muscled passage that coiled around the digits immediately. More black liquid spilled from her twitching sex as she massaged her fingers underneath her clit. Like nothing she had experienced before. Bulging. Swollen. And– "NHGGHAA! COMING!" Her clit erupted violently, stretching out its protective hood as it grew to an impossible size. The pink organ transformed further. Its head became bulbous, shifting from pink to purple, forming ridges and taking on other inhuman features. It seemed prehensile as it swung and rose to a height suitable for Mariana's dark majesty. Catching up, the hood had become a protective sheet for her second sex. The first merged with the base of her cock.
Both craved attention. And the demoness, ever sinful, was eager to indulge them.
Mariana's dark masturbation was interrupted by Tania and Jessica as they entered through the bedroom's door, alerted by the cacophony and fearing for both Jim and Mary's safety. They were panting from the exertion but seemed to forget about the lactic acid burning in their stomach as they stared agape at what the holy sister had become, "… no, Mary!" Jessica gasped as she was the first to understand the situation. Or first to manage to summon the courage to speak up. The young woman quailed and shirked as she then bore the full brunt of the demoness's wicked and fanged grin. To the credit of her purity of will and faith, Jessica recovered and fumbled with a necklace. It bore a golden cross that she held out in front of her as a protective charm, her hands shaking. What a useless trinket!
With a bellowing roar, the demoness let out two billowing tendrils of black smoke. "Do not resist. Tania. Jessica." Initially formless, the corruption shaped itself into gaseous mockeries of serpents and coiled in the air before diving toward the pair of young women. Like before, Jessica reacted first as she pulled on her friend's clothes. That seemed to have brought Tania out of her paralysis as together they ran screaming back into the main chapel – toward the church's main entrance as if reaching it would ensure their salvation. The fiendish behemoth followed them, her throat rumbling with malicious laughter as she burst through the wall, caring little if the building, everything, collapsed. Her surroundings were cacked in mortared grime and rubble, but the indigo-skinned and scaled demoness was untouched by the havoc.
Jessica and Tania could hear the sounds of pews shattering against stone encroaching on them, though they kept their composure by not turning back as Lot's wife had done before turning into a pillar of salt. A far worse fate awaited them if they paused for even a second. All, however, seemed lost as the ringed handles of the doors clattered uselessly without budging. Jim, meanwhile, had a been left a clear opening to freedom through the cementary. All he had to do was not touch the black pools, climb over a pile of debris and then run as fast as his legs could carry him. Though, that meant leaving Tania, Jessica, and Mary to the Corruptor.
"Do not resist," Mariana repeated. "Accept this gift I am offering!" There was a delirious and demented undertone in her cadence as she spoke. "The Corruptor's power is yours–!" She groaned manically, dark veins erupting like fault lines across a craggy surface as she stretched every surging muscle and sinew in her gigantic body. Her bones cracked as she struggled to contain the quaking aftershocks of her growth. "ARRGgghhhHH! Yesss! It feels so good! More! Give in to your QUEEN, Tania! Shed your weaknesses, Jessica!" The smoky serpents swirled around the pair of teenagers, slithering along their bodies as they waited for their answer.
