Corrupting Sex

"Take, don't beg"

Those words were seared in your brain as you increasingly raised the stakes with the Succubus, getting more and more depraved. It had started with you shoving her, a complete stranger, into the ground and kissing her, letting your tongue in her mouth, where her serpentine equivalent did things you had never imagined with your own.

You weren't going to stop there. You wanted to be corrupted, your soul had completely accepted its destiny and your future as a sexual demoness. Your fingers ran over her heavy breasts, enjoying their weight and firmness. You were jealous of them, you wanted yours to be just as big. And you knew what to do to get them.

Your right hand reached the succubus' wet pussy and quickly began fingering her and rubbing her clit, eliciting long moans from her. Your girlfriend had praised your skills over and over again, and you wondered briefly how she would react if she saw what you were doing right now. You were confident in your experience in bringing women to their orgasms, but this demonic being would surely stretch you to the limit of your abilities.

You had one more ace in your hand, however. As your right hand kept pleasing her pussy, your left hand swiftly catched her tail swishing in the air and with no hesitation inserted its thick cock-shaped tip into your own snatch.

"Fuck!", she yelled, throwing her head backwards, completely taken aback by your initiative. She was rapidly losing control, sloppily thrusting the tail in and out of you, feeling better than any dildo you ever tried. You held your moans and began to lustfully kiss her neck, as her long tongue lolled out of her mouth, mad with pleasure.

"Take, don't beg", you remembered

There was no doubt. You were the dominant one here. Already you could feel your breasts and ass expanding, your waist thining and forming a feminine six-pack, your facial features sharpening. But that wasn't enough for you. You needed to be perfect.

You needed to be a succubus.

"Cum in me, slut!", you ordered, with an authoritative yet sensual voice you most definitely didn't have before. "Fill my pussy! Fucking change me!"

Her tail-cock exploded almost immediately, as if awaiting your command, flushing it's dark seed into your body. You milked it as much as you could, using it to fuel the rest of your transformation. Your body became even more sensual, far better than you have drawn, indeed, better than you had ever imagined.

Your demonic features came next, as the transforming fluid in your black veins turned your skin into a burgundy red and made your sclera devoid of any color, reflecting your corrupted soul. Two horns sprouted out of your forehead, your tongue extended outwards, and the most welcome addition of all, a cock-tipped tail, with an almost coke-can girth.

Your senses were sharper, allowing you now to hear the heartbeats of your roommate in the next room. In the corner of the room, your drawing stood testament for what would inevitably happen. She was about to be first member of your harem

No, you reconsidered. Not the first.

You stood up with feline grace, admiring the way your ample breasts heaved with each breath. You spoke assertively, directing your words at the still recovering Succubus on the ground. "You will stay here, my pet. Are we clear?"

"Yes, mistress", your corruptor answered, slavishly.
