"...Of my new hybrid species, merging two monsters known for their insatiable lust!"
You need wait but a second before your fears are realised. A magical circle appears below you, cabalistic symbols spinning clockwise and counterclockwise. You see stylised flames, and sexual imagery. But another circle appears at the same time on the ceiling above you, and looking up, you see foxes and the phases of the moon scattered amongst the rotating runes.
"Wha..." Light begins streaming between the two circles, and you feel yourself lifted into the air between them. Thicker spirals of red energy begin to coil around you.
"Mate!" Darin grabs the bars of his cell. "Hold on!"
You can't reply, scared almost to breath. The glow becomes more intense, the circles spin faster. You can barely see beyond the curtain of hellish radiance that has formed a cylinder around you.
And then a beam of crimson light shoots from the centre of one circle to the other, stabbing through you. You scream in shock and fear.
But instead of the pain you expect, hot lust surges through you. Your cock reaches full mast instantly -- only to compact and pull back into you, your balls sucking up into you and your sac splitting and puffing, hot liquid immediately gushing out over your inner thighs.
Like fire, a spark of smooth red skin is kindled over your heart and quickly spreads, burning away your body hair with flames of pleasure. Your breathing accelerates as you watch your chest expand, your pectorals erased by two smooth red globes of tit flesh, your areolae expanding into large circle of blackish red, your nipples fat and lewdly erect. Sweat beads and runs over you, making your soft, new flesh shine in the hellish light.
As the red tide reaches your elbows -- melting your muscles along the way -- it changes into soft black fur, which quickly envelops your hands, pads emerging on your palms and fingertips, the latter sprouting wickedly sharp black claws instead of your old nails. The same happens to your legs, silky black fur spread down your calves, warping your feet into paws.
You feel your skull shift, your manly features drawing into a woman's, your dirty blond hair turning raven black and growing out to cascade down your shoulders. Then there is pain -- a pressure in your scalp, your eyes burning. You blink, feeling tears, and your eyes completely change from human to demonic yellow on black, with slit pupils. Your ears push up onto your head, becoming black velvety triangles. Your canines sharpen into fangs behind plump lips.
The energy continues to pour into you, filling you. You're sucking in air now, struggling to breath against the knot of conflicting forces in your core. Shuddering as your body contorts, breasts swelling even larger, hips and ass rounding out, shoulders and waist pulling in. You gasp, then suck in another deep breath.
Then the two forces merge with you, igniting a vortex of primal and infernal power. You scream anew in crazed ecstasy, arching your back. At the same time a pulse of magical power explodes from you, hurling Darin and the others back against the far walls of their cells. Black horns emerge and curve back over your head, great red-limbed black wings unfurl from your shoulders, a long, furry tail, red tagged with black, shoots from above your ass, a black barb laden with aphrodisiac hidden amongst the fluff.
You relax, inhaling, then arch and scream again, louder, fiery pleasure racking you. Femcum shoots from the heat of your pussy, arcing across the corridor to mark the man across from you, followed by another, stronger magical pulse. Then the light and the circles fade, leaving you floating in the air, panting harshly after your orgasmic transformation. The scent of men invades your more sensitive nostrils; you can now sense lust and fear, and it goads a new hunger in your lower belly, whetted rather than sated by the taste of female pleasure you've just had.
"By the nine hells," mutters Darin. "What has he done to you, mate?"
Your ear twitches and you look to the mercenary. At first, all you see is a chiseled male with a mouth-wateringly thick cock and hefty balls. He's not erect, which is insulting -- but you can fix that, you think, swishing your tail with a smirk. One sting and, whatever his preferences, you'll have your way with him.
"PERFECT," booms the voice. It snaps you out of your predatory daze, and you feel momentarily sick as you recognise your friend. You avert your gaze, as the wizard continues. "You are exactly as I hoped you'd be!"
"What've you done to Nate, you fucked-up bitch!?" yells the mercenary, pushing himself to his feet.
"SILENCE! Or I will bind you and give you to her before the game begins!" The voice laughs ominously. "Not that it matters. I will enjoy watching you fools bumble about my labyrinth, but you cannot escape her! She is the perfect mix of succubus and werevixen, the first of my beast demons! I call it the 'succuvix' for short. The only thing on her mind is FUCKING every man she sees into another beautiful, lust-addled beast like her!"
Damn, you think to yourself. He's right. You're quivering, your body screaming for you to burst out of this cage and ravish the humans around you. At the moment your link with Darin is the only thing giving you the power to resist, and with this awesome feeling of lust and magic surging through you...
"Shit." Darin looks away from you for a moment. "Sorry mate."
"NOW for the rules of the game!" The wizard's voice drowns out your friend. "You have ten minutes before I release the succuvix. Find the exit, and you will be free. I will even be so gracious as to restore your clothes and gear. But if she finds you, she will infect you, and you will join her as members of my harem."
"NOW GO." The cell doors all open -- except for yours. The humans hurry out. Darin gives you a look, but seeing the hunger in your eyes, does not wait and jogs out after the rest.
