Sapphire, the submissive mistress

"Can I get her to be a bit more submissive?"

The doctor raised an eyebrow, "You mean like a sextoy?"

"I mean-"

"No worries, a lot of couples have been going with that option. Helps spice up things, as far as I understand it."

The doctor took John to an observation room. Sarah was lying asleep on a bed behind the glass.

"She can't see you but we have a few questions for you to ask to make sure she's alright."

John nodded and got to asking her the questions. When she woke up she was like a scared little animal, but soon she felt more calm and answered the questions. She could remember basic information about general knowledge, but nothing about her life.

"Your name is Sapphire," The doctor said, "Your boyfriend John will be taking you back to your home, understood?"

"Yes, sir..." Sapphire said.

The doctor turned off the intercom and handed John a device like a car fob. "This will control her personality allowing her to switch between Sarah and Sapphire. I leave it in your hands."

"Thank you, doctor."

The doctor clicked the button before handing it to John.

"Are you feeling alright Sarah?" the doctor asked.

"I'm fine, when will the procedure be done?"

"I already is."

And with that John and Sarah went home.
