"You need a dick in the ass, Millie"

I say and look at Millie.

Ashley looks relieved, while Millie looks shocked. After a short while she asks:

"And why is that?"

"I am taking over as man of the house as of now, and I will demonstrate my dominance over you by fucking you in the ass." I respond .

Millie looks massively confused, so I say:

"If Ashley is jerking my cock, don't interrupt, but you can ask if I would like you to join."

Millie seems to understand, she thinks for a while, then asks:

"Can I just suck your cock instead?"

I give her a very mild slap, then say:

"Be quiet."

Then I look over at Ashley and say:

"Go find something to lube her with."

Ashley gives me a delighted smile and walks out of the room.

I look at Millie, she looks very nervous, so I say:

"Strip of your dress."
