Andrea and Luna are competing to see who can take the most belly punches. These are focused on going very deep and held for about 3 seconds. They hit the belly button and cause each girl to bend over and slightly push her butt out. Sexy oomps are emitted against their will. Their facial expressions range from fully stunned with eyes wide and an open mouth to ballooning cheeks with their mouths closed.
The punches are so intense, that each girl will grab the arms of the puncher while their fist is buried in their stomach.
The punch becomes so intense, that the loser (it is a surprise!) has an orgasmic reaction which causes her to fall to her knees and hold her belly.
