Not what you think

I don't think I've ever seen boobs used in quite this way to indicate running in a static image.
I like how they’re all in step.
Only they're not. The one at the rear is on the opposite foot, and her arms swing opposite, yet her boobs are in synch with the other two. We're going to have to do a little research to determine which is correct.
I really hope this was from someone's campaign.
Just read the webcomic (definitely spicy, but overall good) and its an in-universe campaign.
