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
A long, black, serpentine tongue pushed deep into their mouth. It slipped down their throat and filled their mouth with inhuman saliva. Feeling utterly violated, Charlie's watering eyes met the unblinking stare of his single giant eye. Long thin fingers began to tease across their chest, gently tracing their body. Charlie gagged around the pale demon's tongue as a jolt of electricity suddenly jumped from his finger to their skin. Shock after shock sent their body into spasm, their orifices clenching around abyssal appendages.
While they'd been distracted both the tentacle and the cock had steadily pushed deeper and deeper inside them, till the impossibly thick cock was fully buried inside. As the pale demon withdrew his tongue Charlie wriggled their hips and moaned at how unimaginably full they felt. Slowly the appendages began to fuck back and forth, the tentacle in undulating curling waves, the cock in insistent thrusts. As the monsters built up a rhythm Charlie's head rolled to one side, and they saw what was keeping Mistress so occupied.
Her doppelganger was on her back, with Mistress's cock buried inside the cunt. The tail was wrapped tightly around the base of her cock, and the doppelgangers hands were wrapped round her throat. Mistress's face was distorted by thick facepaint, and twisted in desperate overstimulation. Tears smeared the mask as she fucked with a mindless need. The doppelgangers face was twisted by manic hunger, savage and inhuman as it exerted it's power through demonic rites.
Charlie's attention was torn away from the spectacle as the pale demon's fingers stopped torturing their chest to position their head on his long pale cock. Soot coloured precum smeared on their lips as he began fucking his cock into their mouth. The three creatures settled into a rhythm and for a while Charlie was lost in sensation, their body singing with overstimulation yet unable to cum. A perfect slutty Sacrifice, a collection of holes servicing three demons in perfect synchrony. Then the demon in their cunt began to speed up, pounding them harder and faster as they screamed in wordless ecstasy. Without the infernal lube they never could have accommodated such violent treatment, but with it their body adapted as the pain was sublimated into ever greater heights of pleasure. With a final howl the horned demon tensed and came inside them. Their cunt burned with demonic heat as impossible volumes of cum filled them. It spattered out onto the floor as they pulled out, to be replaced almost straight away with another tentacle. The three creatures exchanged unintelligible syllables, slipping in and out of human hearing, after a few moments they seemed to reach some consensus.
Charlie felt tentacles turn them in the air, flipping them over and positioning their ass ready to be fucked. The horned demon positioned themself at Charlie's mouth, the thick head of their cock pressing against their tongue. Charlie couldn't quite believe that had been inside them, they couldn't even get the bulbous scaled head inside their mouth. The tentacle filling their cunt began to undulate, massaging every inch of their hole at the same time. The pale demon replaced the tentacle filling their ass with his own cock, to Charlie's surprise it seemed normal, pleasantly filling without being too much. Charlie whimpered as the horned demon's wickedly sharp claws raked down their back. They writhed as their body sang with exquisite pain, then returned to worshipping their cock with renewed fervour.
Spurred on, the pale demon began to thrust into their ass. As he bottomed out in the pliant fuckhole, a spark jumped from the tip of the unholy cock, earthing in mortal flesh. As Charlie gasped at the sensation, long fingers took up position on their clit. They whined as the boney digits skillfully massaged the sensitive flesh, torn between the futile hope of an orgasm and fear of the threatened shock. Another exchange of guttural syllables, then Charlie realised that the monsters were sharing a laugh at their depraved predicament. The thick tentacle in their cunt began to swell and pulse, Charlie felt it push half a dozen eggs inside them. They squirmed at this latest violation, each egg was an inch across and throbbing with power.
The horned demon grunted and growled, Charlie's eyes focussed with some difficulty, and saw their Mistress. Dishevelled, her makeup smeared and running around the human eyes, she was using her hands to massage the horned demon's cock. The pale demon in their ass began to send shocks though Charlie's clit as his thrusts sped up. They spasmed helplessly, caught between throbbing pain and overwhelming, unreleased pleasure. The whimpering and tears seemed to be what it took to push the horned beast over the edge. Thick, hot demon cum exploded out of their cock, filling their mouth and painting their face and chest with black streaks. A moment later the pale man came inside them, an extra large shock jumping from his cock, through their hips, and earthing on his spindly fingers holding their clit.
