Barefoot and dressed only in a thin white onesie, Charlie shivered slightly as they walked down into the basement. But as they saw the scene laid out before them, the cold was the last thing they were worried about. A heavy stone altar, ringed with candles at the five points of the pentagram, and heavy steel shackles at the corners. Their mistress awaited them, a blood red corset with black lace peeked out from below her silky black robe. Her face was painted into a monstrous mask, demonic eyes stared out from all over her face, her mouth a grotesque snarl.
Charlie's mouth slipped open as she sauntered over to them, a hooked knife held casually in her hand. "Are you ready for me pet?" Her sultry voice, combined with her appearance, rendered them all but speechless.
"Yes Mistress," they whispered, trembling with more than just cold now.
"Do you freely offer yourself? Body, heart, and soul?" Her voice held strange cadences, resonating through the room.
"Yes Mistress."
"Do you pledge to serve me gladly, in pursuit of our profane purpose?"
"I pledge myself Mistress." They felt a rush of power as the pact was sealed and their Mistress's eyes, two real and five painted, burned red for a moment.
"Follow me Sacrifice." Charlie bit back a moan at the images that word conjured, and followed her over to the altar. The clink as she set down her knife echoed through the shadowy space. They lay down on the cold stone and whimpered as the heavy shackles closed on their wrists and ankles, spreading them out across the dark red pentagram. With a soft growl Mistress picked up the knife and hooked it under the loose cotton covering their body, cutting down the front from neck to cunt with a single smooth motion. Charlie squirmed helplessly as she set the knife down and pulled the cut wider, exposing their entire torso and thighs. Another minute or so and the rest of the outfit was reduced to shreds, and Charlie was entirely exposed. Their nipples erect and their cunt already glistening with arousal.
Mistress reached over and, almost absentmindedly, pinched their nipples with cruel strength. She grinned as they moaned, their back arching up, chains clinking as they strained against the restraints. Her left hand slipped down and pushed inside their cunt, while her other hand picked up the first candle. She fucked them the whole time as she dripped wax on them from each candle in turn, chanting in demonic tongue as they yelped and begged for the orgasm she skilfully denied them. Her hand continued to tease their eager cunt as she set the last candle down, and dipped the fingers of her right hand into a bowl. They came out slick and red, and she reached down to mark Charlie's pale flesh with strange sigils, softly chanting the whole time. Her hand sped up as she traced the final sigil just above their bush. Charlie whined as they felt the magic wrap around them, knowing that orgasms would remain out of their reach until the ritual was completed.
Satisfied with her preparations, Mistress pulled out of their tight cunt and shoved her wet fingers into their mouth. Charlie moaned and sucked eagerly at her hand, reveling in the taste of themself. They moaned in desperate hunger as she replaced her fingers with the ghastly mask painted over her features, kissing them deeply with savage hunger, all tongue and drool and filthy intent. She pulled away, leaving smeared face paint on Charlie's face, and shrugged off her robe. Her cock was thick and achingly hard, already slick with precum.
Charlie squirmed at the sight of it and wriggled their hips. "Pleeeeeease Mistress ..."
Her response dripped with cruel dominance. "I'm not here for your pleasure. You are my Sacrifice to defile as I see fit."
They whined at the retort "I'm sorry Mistress. I just want to be filled so badly!"
"Filthy, deviant Sacrifice." Mistress positioned herself between their legs, and with the last word thrust deep inside them. They gasped at the sudden intrusion, trying to adjust to her girth. Merciless, she set a punishing rhythm, demonic chants setting the pace as she fucked into her Sacrifice's cunt. Their moans mingled with the inhuman syllables, winding into the dark magic as Mistress' thrusts became more and more frantic. Finally she threw her head back and let out an unearthly howl. All seven eyes burned red, and the five candles exploded into pillars of flame as she came inside her Sacrifice.
Charlie bucked in helpless need, so desperate for the orgasm magically kept just out of reach. They felt the cum inside them as Mistress pulled out, whining at the sudden emptiness. Then they saw the Others, coalescing in the shadows. One of them wore Mistress's body, naked and unmarked by the paint that coated the real one. The only differences were a cunt in place of a cock, and a slender pointed tail curling up her back. The mirrored couple embraced in an obscene display of vanity and desire, hands and mouths greedily claiming one another
The rest looked far less human. A scaled muscular demon with razor teeth, and sharp claws, crowned with curled horns. Charlie's eyes drifted down, blushing at the monstrous cock already standing at attention. Another was simply a mass of slick, writhing tentacles, ranging from a quarter of an inch to four across. The last was eight feet tall and as white as fresh snow. With long spindly limbs and fingers. Their face consisted solely of one giant eye, and a charcoal black mouth.
Mistress pulled away from her demonic doppelganger and grinned at Charlie's expression. "Would you like to provide some entertainment for the rest of our guests Sacrifice?" Her voice taunted Charlie with their own depraved desire.
Beyond any kind of restraint, they responded in a desperate whine. "Pleeeease Mistress! Please let me service our guests. I want them to use my holes and fill me with monster cum!" With a smirk she drew a complex pattern in the air and the shackles sprung open.
Tentacles shot out and dragged them off the altar, lifting them up and bending them to expose their holes and spread them open as much as possible. The supple limbs oozed a thick slime which made Charlie's skin tingle and heightened their arousal, they gasped as a thin tentacle began to rub the oil into their ass. It stimulated and loosened them till they were desperate for more. As the tentacle monster did this the horned demon strode across the room and used their clawed grip to pull Charlie's thighs open. A savage snarl sprayed spit over a face twisted between fear and desire. Slowly, the impossibly large scaled cock began to press against their cunt. Tentacles massaged the ethereal lube into it, as inch after inch of monstrous cock stretched Charlie out. They threw their head back and let out a wordless cry at the intense sensation, until it was stifled by the pale demon
