Barbara's got the tits

You choose Barbara. While Harley had such a nice ass, that would still be there in a while. Batgirl, however, was resourceful, and would eventually break out. You play with her now erect nipples, poking up through her suit. Fortunately, her suit was two pieces, so removing the top wasn't a problem. Now you have her juicy breasts in front of you, just asking for it.
