Just leave her mindless

"Okay, Delia!" said Ash. "Come on out!"

He threw the Pokeball, and Delia popped out, naked and in a trance.

Ash had an idea, and a strange Pokedex appeared in his hand. Well, it looked like a Pokedex. In reality, it was called the Woman Dex. And its first entry...

Delia; the Mindless MILF Woman. This permanently naked woman is also permanently entranced. She views her Trainer as her master and will do anything she is commanded without hesitation.

"Anything she is commanded, huh?" Ash wondered aloud, looking his naked mother up and down.

"Masturbate," he commanded.

"Yes Master."

Delia stuck her hand in her pussy and began to masturbate, keeping the blank look on her face.
