She forgets you're a powerful mage. Turn her mortal.

This desire demon was a fool! She doesn't know the power you possess ever since you're drank from the 'Well of Sorrows'. You reach out towards her and a white arcing blast of light hits her chest. Kitty screams in pain very briefly before the light subsides. Smoke rises from her as she's keeled over but she rises again... feeling different.

"What... what have you done to me?!", she asks you angrily. Her tits jiggling as she takes an offensive stance.

"I've made you a mortal Kitty! You now feel and live as we do", you reply to her with arms crossed.

"No... no this is impossible", says Kitty. She snarls and tries to rush you but trips over, stumbling. It was a little harder to walk with hooven feet when you've lost your natural sense of demonic movement. The desire demon's body had not changed visually except for her now human eyes. Same horn, same hair, same tits and ass... just a lot weaker and powerless. A single tear falls out of Kitty's eye, "how could you do this to me you wretched human!".

You stop forward towards her, rubbing your cock, "now that you're mortal Kitty, you'll be a lot easier to punish. Let's see how confident you are in your body without demonic energy protecting it", you tell her.

You were now ready to pass judgement on the desire demon.
