"...yes."

"Let's try this- Yes, Mistress."
"Yes, Mistress," Kira says, shuddering a bit.
"Very good. Let's play 'Mistress Says.' Mistress Says bend over the couch and point your ass towards me."

Kira obeys without question.

Your wife Brandi unzips and removes Kira's skirt.

"Mistress Says remove my skirt, all while looking down away from your superior."
Kira obeys again, not looking at Brandi as she removes her skirt on command.

Both are now down to just panties.
You have a great view of this.

"Mistress Says suck on my tits. Worship them."

Kira obeys yet again, enjoying this a whole lot!

"Good job. You'll make a good lesbian yet.
Of course, don't forget about my Husband. It's all thanks to him that you even get to have me. Mistress says thank him."
"Mmm...thank you," Kira says, looking up for a moment and going back to those tits.
"You'll get to have me and then he'll fuck us. Do you want that?"

Kira stops sucking and hesitates, her body language getting stiff.

"Are you questioning your Mistress. Do you need to be punished?"
