Go look for clues

"We should head back up to the rooftop and try and pick up Catwoman's trail." You suggest.

Batgirl nods and you head back out to the front of the building, staying far enough back to watch her naked ass. Batgirl fires her hook again, clutching you tight before ascending to the roof.

Batgirl looks around from roof to roof, "It's no use, she's long gone."

"Don't talk like that, there may be some clue. Look around the roof for evidence." You tell her. Batgirl gets down on her hands and knees, pointing her naked ass in the air as she thoroughly inspects the rooftop for a sign of Catwoman. You watch her pussy sway from side to side as she investigates.

"Hey, you should be looking too!" She shouts at you over her shoulder.
