Ask to be your true Partner

You wait a second for the inevitable knock on the door. You tell your man to open it.

"Yes?"
"I...want to be your partner- for real this time," Jenni says.

Huh?!? That's not what you were expecting/hoping to hear!

"Come again?"
"I want to be your Partner. I'm a Submissive...but I only want to be submissive to women. I won't be your ****, but would be happy to be punished by any Dominatrix or other **** that you want. Will that satisfy you?"
"So that one time we had together..."
"Was fun...I guess. I just...I just don't like losing control to men so much. That man who controlled me, he...ruined it for you.
I'm sorry- I can't help it.
All my favorite times as a bottom were with women like Mistress Rose..."

"...your Dominatrix and that one time I had to go undercover in an Erotic Wrestling League.
We thought that they were involved in trafficking, but they weren't.

I sure got my turn being punished before we found out though."

"With that said, I have no other family to go back to. I don't mind you keeping them as Sex Slaves.

I'm even willing to let you make them fuck me...or whatever. It just can't be you or him.
I'm sorry- but that's how it is going to be."

You think for a moment, trying to make things very clear.

"So, to be clear, I can take you on as my proper Partner, but never get to fuck you again. Or..."
"I move out of town forever. I'm sure that I can find Ms. Rose on the East Coast if necessary."
"You'll understand my lack of trust, considering how this all started," you say.
"Of course. You have something in mind, I take it."
"I do. Come this way."

You lead the naked Jenni to a room with a Vacuum Bed Chamber. She doesn't seem shocked.

"This won't be your first time, I take it?"
"No. This will prove my obedience to our cause and show that I trust you to let me out, right?"
"Exactly. You know that I could trap you here, but you will willingly-enter and trust that I grant you freedom later."
"Very well. Put me in it."

You eventually get her sealed in for the day.

It's not what you were expecting, but you can work with this.
