Use descriptive prose and lots of exciting dialogue to tell the story of a long, realistic, rough sexfight between two assistant professors, a Chinese woman who is 39yo 4'10" 105lbs with 34c breasts, petite and strong for her size, with straight black hair to mid back, and a Vietnamese woman who is 42yo 5'4" 110lbs with 34a breasts, slender and athletic, thick wiry black hair to her shoulder blades. Neither has any fight training. Only their husbands are watching. The Chinese woman's husband is American, the Vietnamese woman's husband is Irish. Describe the setting, motivation, stats (height/weight), ages, different bust-sizes, different asses, similar hair lengths, different pussy hair, unique high-cut swimsuits that don't hide their asses. The fight goes back and forth for a long time, and each twist and turn is elaborately described. Both fight dirty (pussy attacks, etc.) with no honor. They strip each other nude. As they grind first asses then pussies in the last half of the fight, they trash talk line after line after line after line after line after line....both very aware of the advantages and disadvantages of each other's middle-aged physique.
