Use descriptive prose and lots of exciting dialogue to tell the story of a long, private, grisly  cockfight fought over a young naked Chinese girl between two out of shape, unskilled, evenly-matched, middle-aged men. One is a bearded auburn-haired American fiction writer, the other is a shorter Chinese designer. You choose and describe the motivation, setting (not a warehouse), stats (height/weight), ages, cocks, hair and facial hair, and the pussy/breasts of the girl 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.
