Beat his ass

You rub the bridge of your nose, grumbling to yourself. "Yeah, go for it," you sigh. "I really don't care any more." Batgirl's mouth shifts into a sadistic grin. No words are spoken as she flies into action. Leaping forward, she uses her momentum to hurl Charles into the ground. She twists herself around him and forces him into a submission hold, releasing his grip as the knife clatters on the floor. Charles cries out in pain, but Batgirl has only just begun. She flips him over onto his back and straddles his flabby stomach, facing his feet.

Then she punches him in the dick.

Hard.

Charles screams in agony as Batgirl punches him again and again. Over and over she pummels his crotch, grunting with the exertion each time. You notice Charles screams fading into gurgles, and you feel true sympathy.

"Jesus Christ! That's enough!" you shout, unconsciously holding your own genitals. Batgirl's fist stops mid-swing, and she remains on the likely-eunuch's body, lightly panting. She stands up, but quickly turns around and gives him one last kick. You watch her carefully as she walks over to the mannequin and removes her costume. While she puts it back on her body, you make sure to give her plenty of space.

Finally geared back up, Batgirl turns and leaves the room with a surprising spring in her step. You follow her outside cautiously, promising yourself to never get on her bad side. As you reach her bike she quickly spins around and asks, "So where to next?"
