The skin on Laurie's back began to itch and burn for a moment before leathery wings like those of a succubus burst from her back. The wings grew from about the size of a bat's wings to a larger size.
She felt her breasts grow, larger than most men would ever see yet firmer than they could ever dream. Most men would find them practically hypnotic. Laurie gave her chest a slight jiggle. "Perhaps literally hypnotic..."
She flexed her hands and her nails grew into sharp points then retracted to normal. Anyone who crossed her would now feel pain.
Her legs began to feel momentarily weak. She was forced to sink to her knees for what she expected would be the last time. Her legs drew together, forming a single appendage. Her knees and feet melded into this new appendage which grew in length from where her feet had been. Scales formed along her new tail, up what had been her legs but leaving her ass (which was now even more perfect than it naturally was) and vagina. She could quickly by slithering, faster than any snake. And her tail was stronger than any snake's - she could crush any man wrapped in her coils.
Every trace of hair, except for her eyebrows, eyelashes, and the hair on her head vanished, leaving her with perfectly smooth skin.
She was more than a naga, more than a succubus. The amulet that had made it all possible hung just above her perfect breasts.
Now where to begin?
