A Royal Spanking!

The now-truly-exposed pair are matched into the main Building and into a room that is crudely-made-up into the Main Hall of a Castle. It looks like something out of a High School Play!

The Red Queen sits in front of them in a chair to make her decree.

"Cheshire Cat- you are charged with stealing my tart. How do you plead?"
"I didn't steal a tart. I don't even eat gluten," Catwoman exclaims.
"...I think...she means me," Batgirl all but whispers to Catwoman.
"Oh....oh shit."
"Silence! Your plea is noted...and ignored. I say that you are guilty! Guards, turn her around for her punishment!"

Catwoman continues to struggle, but it is no use. She's turned facing away from the Queen and she probably knows what is coming next.

"Tweedle-dee. Tweedle-dum. Spank this cat's ass until is as red as my hair!"

The two fellows waddle over from the side and nod happily. They each strike Catwoman's tight ass in unison.

As this goes on, the whole façade of Catwoman's strength fades and she resorts to simply crying out sadly in pain from the spanking. Batgirl can only watch...and wait for her turn.

The sometimes-Villain had only been spanked this hard once before...

They finally stop after a couple of minutes. Catwoman simply whimpers. The men let go of her arms at the Queen's wave.

"Turn around to face me."

Catwoman does what she is told.

"Now get on your knees."

Catwoman acquiesces.

"Thank me for punishing you," the Queen says, pushing her luck.
"...thank you for spanking my dirty ass red," Catwoman says, making Batgirl gasp.
"Very good. Since you showed such humility, I will grant you some relief for said dirty ass. Who do you want to rub your ass with some salve from the Tulgey Tree? I will consider the request if you ask me nicely enough."
