Fiona takes the lead.

"You're my slut," Fiona says, "Aren't you?"
Leah gulps.
"I can't hear you."
"I'm your slut," she says.

It's a start.

"I didn't say to stop."
"Finger me, slut. Say 'Yes, Mistress.'"
"...yes, Mistress."

Leah begins to finger Fiona, starting to enjoy it.
'This could be alot worse,' she thinks.

You move in closer to see, which makes one of them happier than the other.

Leah tries to zone you out and fingers her, well, Mistress.

She begins to get good at it as Fiona keeps up the dirty talk.

Fiona is near orgasm when you speak up.

"Let's see you two switch things up," you order.
"Maybe...give us another minute," Fiona says, less assertively than when she talks to Leah.
"I think not. Now switch places, you two."

Fiona sighs and gets up, letting Leah take her place on the edge of the bathroom's raised area.

Fiona gets on her knees, not sure if she wants to play the game this way.
She looks at you.

"Did I stutter?"
