Symbiotic Magic (Magic Transformation, Futa/Fem, Weirdness)

I know what you're thinking: "Luvbster! What the hell is this? Where's chapter 14??" To which I reply: "Shut up and read my story, jackass!"

I'm still working on aMMiH, but I felt like doing something different, so I slapped this short story together in two days. Hopefully I got it out of my system.

EXTENDED WARNING: I don't think there's anything particularly off-putting in the story, but there's scene of someone tied up and fondled for a bit if that bothers you. Also it gets kinda weird in the second half; you'll probably know if you want to continue or not when the character of Elise is introduced.

“I have no interest in coin,” her beauty was marred by a growing evil smile, “What I want cannot be purchased from a merchant.”

“What is it?” Arianne asked, both hopeful and frightened.

“Your body,” she replied, grinning at the shocked response, “I always have a use for new test subjects.”

The peasant blinked. “Subjects?”

“Yes,” she explained, “Much of my magic is experimental these days. My curiosity has only grown in my old age. I need young bodies to try my new spells and potions on.” She chuckled. “It’s so much easier when they come willingly. Avoids that whole torch and pitchfork annoyance.”

“Wha- What would you do to me?” Arianne asked, extremely nervous.

“You must agree first,” she said matter-of-factly, “Or I will not help you.”

Arianne weighed her options. The witch’s proposition was terrifying to her, but her problem was destroying her life. “My affliction is such that I have grown desperate,” she thought aloud, breathing heavily, “I am constantly aroused. Even now, it is a
