I stumbled into the room, my senses quickly filled by the thick purple smoke that billowed from the incense hanging from my room's ceiling. As my eyes shifted to the heart-shaped bed, I watched the sultry succubus stand. The silhouette of her hourglass figure was striking. My pupils dilated as I took in all of her features. Thick smoke filled my lungs, and my anxiety started to melt away, replaced by surging adrenaline and arousal. 

"Welcome to my humble abode," she purred. As she pulled me into her supple bosoms, I was overwhelmed by the sweet flowery scent of lilac. "I was not expecting a male to be chosen as my next student. You mustn't fret. Being a succubus is a truly wonderful experience." Her long, well-trained fingers moved under my shirt, causing Goosebumps as I shivered. Her pale skin, long ebony hair, and deep blue eyes completely mesmerized me.

Before I knew it, I was naked on her satin sheets. Those long slender fingers wrapped around my slowly shrinking cock, causing me to shudder. With every stroke, it seemed to shrink a little more. "N-No… stop." A meager whine escaped my lips. Whatever lingering embers remained of my manhood had been smothered by the thick purple smoke. 

I felt this deep pressure at the base of my spine. As the tension boiled over, I felt a massive orgasm erupt through my body, a tail bursting through my skin. I hadn't even noticed the horns that sprouted on my head. My ass and tits started to rapidly inflate and change shape into something more succulent. I felt them inflate and wobble while I cried out in shock and arousal. Every shift and change created a blissful sensation in my body. It felt almost as if every inch of my body was experiencing a mind-numbing orgasm simultaneously.

All that was left of my manhood was my shrunken cock. I felt sweat beading and rolling down my sensitive skin as I groaned. 'This is it.' Her fingers stroked my testicles ever so lovingly as they shriveled and receded into my body. The last orgasm I would ever experience as a male started to wash over my body. I had never experienced such a bitter-sweet orgasm. My cock twitched and throbbed, fighting up until the very last second. Finally, succumbing to the will of the succubus. 

 "Fuck! Ah!!" I cried out as the very last of my semen came shooting out. The last gasp of my manhood before it completely retracted into my body. My testicles blossomed into perfectly shaped labia. I could feel my newly shaped vulva jealously twitch while I was consumed by a deep, primal craving to be fed.

 'Feed, Fuck, Suck, Fill yourself.' The primal desires of any succubus. 

"You must be hungry; I have a prime specimen for your first feeding," the veteran succubus cooed.

My ears perked as my attention was drawn back to the succubus. I was utterly captivated by her words. I needed the life energy of a virile man. I was so, so hungry.
