Mia and Cassie Belly fight

Mia and cassie have a fight. who is stronger? they both think of themselves as stronger than the other. they take turns punching each other in the stomach. some punches are fast and powerful. but the worst is when they press their fists hard into each other's stomachs. it makes them choke, cough, hyperventilate, and in the end they're so tired they sit on the floor and punch each other in the stomach. there is no winner, they both remain losers.
