Cassie and Mia work for the same agency. They both think they are better than the other. Cassie challenges Mia to a duel. They have to punch each other in the stomach in different positions. First they both stand and punch each other. Later, Cassie kneels down, showing her buttocks and Mia's stomach. Then they swap. The last pose is doggy style. Cassie kneels doggy-style in front of the camera, while Mia hits her belly from below. In the end, there can only be one winner, but spoiler: they decide one duel isn't enough because they're both tired, so they'll continue another time.
