"Chloe," you said. "You're up first. Alexandra, go in the closet so we won't be disturbed."

Alexandra nodded and went into the closet.

"So, Chloe, what role in my harem would you like?"

"Sexbot, definitely," Chloe said. "I think I'm much hotter than Alexandra, and I'm definitely curvier!"

"I see," you said. "Okay, you go in the closet now and get Alexandra."

Chloe left, and Alexandra came back.

"What role do you want?"

"Pet-girl," Alexandra said. "I have a lithe body, and blue eyes like a cat. Plus, I think Chloe's into more of that sexual drama crap than me. She couldn't handle being a pet-girl."

They had both chosen different options. You could live with that. You called Chloe back in.

"So," Chloe asked. "Who gets to be what?"

You hypnotized them both again.
