Cross over, but on your own terms.

As you begin to become overwhelmed by the lewd exhibition of wanton debauchery being put on in front of you as well as the overpowering miasma of demon pheromones on overdrive, you begin to feel the world slow down around you. Your sense of hearing fades as the color drains from your vision; soon the succubi and incubi fucking in front of you are doing so in painfully slow motion. Impossibly, you actual start to tune out the wicked orgy in front of you and find yourself focusing on Jess, her crimson figure seemingly the only color left in your de-saturated vision. The wanton succubus that had once been your cute girlfriend looks directly at you with a sultry, knowing gaze, suggestively running her long black tongue between her plump black lips.

Abruptly, you feel your dick start to itch from the dried saliva from the partial blow job Jess tried to give you earlier in the day, when all this began. Oddly, the itchy sensation from the crusted fluids coating your member starts to stimulate you, and before you know it your cock is full erect and straining within your pants; no, not just that, it's engorged larger than you've ever remembered, throbbing, burning hot, and practically overflowing and read to burst. You feel as though you can almost hear Jess' voice in your head, a cacophony of indistinct whispering and moaning. You feel as though you're burning up, a sweltering hot fever spreading across your body. You feel your muscles tensing and your nipples turning rock hard even as your cock engorges more and more.

Suddenly, you become hyper-aware of Megan's presence as she presses against you instinctively for protection, the smell of fear and sweat on her, the body heat coming off of her sweet barely legal figure, her shallow breath and rapid heartbeat. The frightened teen girl is too overwhelmed by the debauched display in front of her being put on by her former friends to notice as you mouth lolls open and you begin to cream your pants over and over again, a foul stain spreading across your crotch. Even after you finish releasing your final wave of cum, your erection does not diminish, but rather grows even larger and more engorged than before. You feel rapturous joy as your human consciousness is annihilated by waves of overwhelming pleasure as your mind is suddenly flooded by thousands of the most utterly wicked and depraved thoughts and ideas. You feel the presence of Jess and Lilith... no, Mistress Lilith inside your mind as you begin to fully embrace the darkness.

The musky stench of your cum-soaked crotch finally catches Megan's attention. The teen girl turns and stares at you in shock for a few seconds, confused, before backing away fearfully eyes wide as saucers as your clothes begin to shred to pieces as you abruptly grow in stature as powerful muscles swell across your body, your previously average figure expanding, hardening, and tightening into a perfect Adonis-like physique as your height grows to over 7 feet tall. As your pants and underwear tear into fragments and fall to the floor, your heavy cock is fully exposed as it doubles in size and girth, throbbing and engorged and aching to fuck. Megan screams hysterically as the monstrous pulsing shaft waves wildly in front of her face, beads of black demonic pre-cum already beginning to well up out of the tip.

Flecks of spittle fly from your mouth as you open it to let loose a bestial roar, exposing growing fangs and a lengthening, blackening tongue that lolls out lewdly to impossible length. You feel your hair flare out into a wild mane that falls over your shoulders and down your back as black horns burst forth from the top of your skull. Leathery bat wings and a long whip-like cock-tipped tail explode from your back and spine, completing your rebirth into one of Lilith's loyal minions of wickedness and lust.

Your glorious transformation elicits a cacophony of triumphant howls, hoots, and cat-calls from the horde of succubi and incubi outside. You see the rutting young demons that were once Megan's friends and family cum excitedly at the spectacle of your transformation, without interrupting their rough fucking. Mick, Jake, and Derek each grin and flash you a crude thumbs up as they continuing pounding into their wanton demon whores, you return their crass gesture of camaraderie with a wicked smirk as your thoughts quickly turn to creating a depraved hellbitch of your own.

Megan looks around fearfully, futilely searching for a means of escape, before you seize her savagely with powerful clawed hands and drag her to the glass wall of the coffee shop, pressing her roughly up against the glass so that the terrified teen girl is pushed face-to-face with her corrupted sister, who's still busy taking an anal pounding from the musclebound incubus Mick on the other side. Megan is **** to stare in horror at the wanton face of the succubus Amanda, as the vile slut that was once her sister leers at her from the other side of the glass, her expression warped in pure obscene ecstasy as Mick violently thrusts into her from behind.

As you hold the teen girl in place, you look up and catch Jess' gaze. The wanton hellbitch purrs approvingly, sultry eyes hungrily appraising your glorious new body as the succubus silently welcomes you to the glorious darkness of Mistress Lilith.
