How about a scene where Sapphire or Demi comes to a bra factory to participate in a study to develop a new sports bra. The idea is that the model will do jumping jacks (aka star jumps) to test a couple of different bras. The model quickly has the experimenter eating out of her hand as the bras get more and more flimsy/nonsupportive, and the scene culminates in her doing them topless to push the experimenter over the edge...
