Korra the legendary avatar was teaching you how to master the elements as good as she did. Everytime she waterbended her huge ass would jiggle wildly in her pants. Whenever you could you would stare at her ass not learning anything in the process because that's how distracting her ass was. She would eventually catch on to the staring and notice how you've went from being beside her to behind her and she would finally address it.

Korra: "Listen. I like ass as much as the next person. Literally!! But Dude, My ass isn't that fucking Hypnotizing, that you can't even learn anymore."

Korra: "Maybe this will finally get him to pay attention at last." She whispered to herself.

Korra: "Now run by me what we just learned or were you too distracted by my ass, that you didn't do anything at all?"
