Batgirl has Batman where she wants him. She did a whole tease on him while he was unable to move. She knows at this point he is in a very vulnerable and ready to be dominated for her amusement. She slips off her boots and puts him in his face to get his cock nice and hard. Batgirl is really showing her evil side when she puts her nylon feet on his cock to pump him until he explodes all over her feet.
