Every alpha slut needs a beta.

"I'm sorry, my dear" Mr Milton says, "but you'll no longer be twins. That said we'll still have an innocent looking redhead, even if she isn't that innocent"

"Wait-a-minute" you butt in, "Who says we can't keep them as twins? What one twin gets, the other twin gets, or something along those lines?"

He rubs his chin, pondering briefly; and looks over to Mollie.

"Can you handle such a close rival?"

Molly thinks about it for all of half a second. "Of course, if it's Mary. I'm sure she'll say the same"

You realise that this means you need to get another person's agreement, but think, If she's anything like Molly, this is gonna be a done deal in minutes.

You cock your head slightly at Mr Milton, and he gets the unspoken message and minutes later Mary is in the room, next to her twin.
