Make them spank each other

Suddenly, Wonder Woman sits down on a bench, pulling Power Girl over her lap. She takes hold of the star-spangled panties, pulling them up between Power Girl's thighs to expose most of her beautiful bottom. Her hand comes down.

"Let me go... ow!"

"Sorry!" protests a bewildered Wonder Woman, as she spanks Power Girl again and again, turning her derriere a lovely shade of deep pink. "I don't know what's happening!"

"Ow! Stop it!" Power Girl's cheeks are flushed bright red as her breasts bounce around, leaping out of the bustier. She's pretty tough, but Wonder Woman spanks very hard indeed. "This is definitely an Amazon sex thing!"

"I promise it's not," says Wonder Woman, spanking her some more. Power Girl kicks and squeals in protest.
