Does Mara finish the transformation into a Bitch or is there interference?

Some Infernal Intervention.

As Mara ate out her mistress' pussy and felt the cock penetrate her, she moaned, her mind slowly shifting and changing to fit her new purpose. She could imagine being fucked in all holes by Succubi, Incubi, and Hellhounds... you served your mistress, no matter what she wanted.

"Yes... bitch... eat my pussy..." Her mistress moaned.

Mara's vision started to blur and after a moment she realized she was crouching down in a fiery throne room. She saw a powerful Succubus sitting on a throne of bodies with Succubi eating her pussy and sucking her breasts. She instinctively knew that this was Lilith, your Goddess.

"You... you're the one my daughter Eve caught," Lilith said with a smile. "Such a shame you're going to be wasted as a bitch... you had so much potential."

"Please..." Mara moaned as you shoved two fingers into her pussy. "I don't want to be a Bitch, I want... I want..."

"You want to be more powerful?" Lilith asked, standing up and walking over to the young woman, taking her face in her hand. "You want to be a powerful Succubus and dominate the woman who decided to try and make you her bitch?"

"Yes..." Mara moaned. "I want to be a true Succubus."

"What will you do?"

"Anything!" Mara shouted out. "I'll do anything my Goddess!"
