Keep enjoying the show

You decide to keep watching. The Joker has a very short attention span and quickly gets bored with Batgirl's pussy. He pulls out and admires the view for a second.

"Is it just me, Harley? Or is your ass much bigger than usual?" He laughs and spanks her. Batgirl grits her teeth and tries her hardest not to punch him.

"I guess I have been gaining some weight Mistah J!" She says, attempting to stay in character.

The Joker laughs as he begins forcing his dick into Batgirl's ass. She grits her teeth again. The Joker thrusts deeper into her ass as Batgirl lets out a little yelp. He continues to laugh as he begins fucking her fast and hard.
