Use descriptive prose and lots of exciting dialogue to tell the story of a long, realistic, nude, erotic and vicious sexfight between two assistant professors, a Chinese woman NAME_1 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 NAME_2 who is 42yo 5'3" 105lbs with smaller 34a breasts, slender and athletic, thick wiry black hair to her shoulder blades. Neither has any fight training. Only their nude 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, different pussy hair, and different nipples (NAME_3's are brown and silver dollar sized). 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. 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 viciously aware of the advantages and disadvantages of each other's physique.
