First step

She drank it in one smooth swallow, the iridescent liquid sliding down her throat. For a moment, nothing happened. Then, a deep flush spread across her chest, creeping up her neck to stain her cheeks. Her breathing hitched, her pupils dilating until her eyes were pools of black desire.

"Remove your clothes," I commanded, my voice low and steady. "And lie down on the bed."

She moved with a clumsy, desperate urgency, her fingers fumbling with the zipper of her dress. She let it fall to the floor, revealing a body that was even more impressive unclothed—full, heavy breasts with dusky nipples, a soft belly, and wide, flaring hips that tapered to strong thighs. She lay back on the bed, her legs falling open, a silent invitation.

I knelt between her thighs, my fingers finding her slick folds. She was already wet, her body responding to the magic with a primal eagerness. I began to stroke her, my movements firm and deliberate, quickly finding the rhythm that made her gasp and arch her back. It didn't take long. Within minutes, she was crying out, her body convulsing as a powerful orgasm ripped through her.

As she came down from her high, I brought my lubricated fingers up to her tight, puckered hole. I circled it, teasing her, before slowly pressing one finger inside. She gasped, her hips bucking, seeking more. I added a second finger, then a third, stretching her, preparing her. Her response was immediate, a wanton, shameless grinding against my hand as she chased another release.

After putting on a condom, I positioned myself at her entrance, the head of my cock pressing against her now-relaxed asshole. With one slow, steady push, I was inside her, buried to the hilt.

Her mind shattered.

A scream tore from her throat, a sound of pure, unadulterated ecstasy as a orgasm so intense it bordered on pain seized her. Her body convulsed, her inner muscles clamping down on me like a vise. Then another orgasm hit, and another, a relentless, overlapping cascade of pleasure that left her gasping, her body writhing uncontrollably beneath me. Her brain was turning to mush, the spell working its dark magic, dissolving her consciousness, preparing it for expulsion.

I continued to pound into her, my own release building, driven by the sight of her complete and utter surrender. After countless orgasms, I pulled out, my own body spent.

And then, it happened.

A long, rubbery, blue thing shot out from her ass, landing on the bed with a wet slap. It was her personality, her essence, now a physical object, separate from her body.

Her face was slack, her eyes open and vacant, her mouth agape. She was gone. An empty vessel.

I picked up the blue, rubbery thing, its surface slick and strangely warm. I carried it to the kitchen, placing it in a blender. I turned it on, watching as it whirred, the blue substance liquefying into a swirling, shimmering smoothie.

A bonus, I thought. I reached into my satchel, pulling out a small, ornate bottle filled with a thick, purple liquid. Succubus pussy juice. I added a single drop to the blender. Should make her sexual experiences much more vivid, I mused, a little extra something for the trouble.

I poured the resulting concoction into a glass and returned to the bedroom. I lifted her head, tilting it back, and poured the smoothie into her mouth. Her body, on autopilot, swallowed, her throat working as the liquid slid down.

I laid her head back on the pillow. Her eyes were still vacant, her face still slack. But I knew she was in there. Her personality, now enhanced with a touch of succubus magic, was back where it belonged.

The first step was behind us. Now came the fun part.
