A Succubus

Carla could sense that Alex's wayward desires had caused his transformation to take a more alluring turn. Casting her slit eyes downward Carla was intrigued by the sight of her former beau's five-inch cock slowly reducing before her. A feral grin crossed her lips as she dove to the floor and effortlessly took the shrinking cock between her hungry lips.

After a few moments, the cock had seemingly shrivelled out of existence, although Carla knew better. Grinning she drove her serpentine tongue down against the newly flat surface of flesh that quivered in response to her touch. Slowly the flesh began to invert, welcoming Carla's tongue deeper inside it. A low purr slid from Alex's darkening lips that slowly inflated into a pair of plumpen cocksuckers.

Carla lightly dug their taloned tipped hands into Alex's expanding hips as they eased their fang-tipped maw away from the rapidly blossoming pitch pussy lips that had emerged between Alex's slender legs.

As Carla brought her newly feminised beau to their feet she parted her fang-tipped lips to mewl; "Welcome to your new existence as a slutty Succubus, Alexa."

Alexa giggled with delight as they melted into one another's embrace ...
