Use descriptive prose and exciting dialogue to tell the story of a long, private, realistic sexfight fought over a naked woman between two unathletic, untrained, evenly-matched opponents. One is an American fiction writer, the other is a Chinese designer. You choose and describe the setting, stats (height/weight), ages, cocks, hair length, and the woman they are fighting over. The sexfight goes back and forth for a long time, and each twist and turn is elaborately described. Both fight dirty with no honor.
