Cassie must find someone for you both to dominate

Cassie is already downstairs having her breakfast. She smiles when she sees you.

"I trust last night was to your satisfaction?" She says confidently.

"God yes." You admit. "The bit at the end when Sandra made you kiss her was just... There's no words for it."

"You really loved seeing me do stuff with another girl?" Cassie ponders.

"That, and seeing a woman take control the way Sandra did. It was just so hot. And I need to see more. To experience more."

"I bet you do." Cassie sticks out her tongue playfully, but there's a hint of uncertainty in her voice.

"But also, there was something about the power imbalance that felt... upside down. Sandra was the one who was the guest to our house and our intimacy. So why should she have been the one to get to take the lead?"

"What are you saying?"

Here goes nothing...

"I want to see you dominate another woman. I want there to be a pecking order that has me at the top, then you, and then another girl you've found at the bottom. You would, like, order her what to do, and how to please me, and how to please you, if you wanted to try it. I would get to sort of lie back and not have to make any decisions for myself, because you would organize my pleasure. But you would only have to do what you wanted to yourself, because you would have someone else do to all the dirty work."

"Like licking your asshole, you mean." Cassie sticks out her tongue again, but this time as an expression of disgust.

"Like licking my asshole." You agree. "Of course, it's probably a moonshot to even think you'd consider such a thing, never mind being able to find someone to agree to serve us like that."

Cassie laughs. "It'd be so much simpler if it was."

You frown. "What do you mean?"

"If I couldn't find someone, it would be easy to say no. But as it happens, I already know the perfect girl."

"You... you do?"

"You know Amanda."

"Your best friend Amanda. Soon-to-be maid of honor at our wedding Amanda. Yes I know Amanda."

"She has been in love with me since we met at university."

"You're kidding me."

"Not a year goes by that she doesn't 'joke' about wanting 'birthday sex' from me for her birthday. And she sleeps with men casually all the time, so I'm sure she wouldn't mind doing stuff with you, if there's a chance of getting to do stuff with me too. I just know she would jump at the opportunity."

"I feel a bit uncomfortable about this idea now. She's your best friend, and she sounds like she'd be emotionally invested in this."

"Look, do you want to fulfill this fantasy or not? If so, this is the way."

Fuck. Fuck. FUCK!

"...If you're comfortable asking her, I would like you to ask her."

"Then I'll ask her over lunch. I'm seeing her today, remember."

"What a convenient coincidence." You remark dryly.
