Tie her hands behind her back.

As she charges you use your magic to make Wonder Woman's lasso fly off of her belt and magically bind her hands together behind her back. This causes her to drop her sword and fall face first, to the floor.
"Well, you said you could beat me with your hands behind your back, lets see it."
She flies to her feet, still bound and attempts to kick you. You use the rope you enchanted to pull her back each time, enjoying the bouncing of her pushed out breasts and as juts back and forth. You laugh as you humiliate the proud amazonian, like a puppet on a sting.
"Do you surrender?"
