金伯利·简和星九在一场腹拳比赛中互殴。他们反反复复地把拳头打在对手的肚子上，直到对手被打得喘不过气来，汗流浃背，咳出了水。Star终于倒在地上，但Kym用绳子把她的手腕绑起来，以进行更多的腹部拳击惩罚。

Back and forth, they sink their punches into their opponents gut until they are heaving from the blows, dripping with sweat, and coughing up water. Star finally topples to the floor, but Kym strings her up by the wrists for even more belly punching punishment.
