In NAME_1's style, tell the story of a long, realistic, nude fuckfight between two assistant professors, a Chinese woman NAME_2 who is 39yo 4'10" 105lbs with 34c breasts, petite yet strong for her size, with silky black hair to mid back, and a Vietnamese woman NAME_3 who is 42yo 5'3" 105lbs with smaller 34a breasts, slender yet athletic, thicker wiry black hair to her mid back. Both have zero fight training. Only their naked husbands are watching, who each claim their cock is better. 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 amounts of pussy hair, different body types, and different nipples (NAME_4's are light brown and silver dollar sized with thick eraser-like areola). The fight goes back and forth for a very long time. Each twist and turn should be elaborately described. Both of these mature women fight dirty with absolutely no honor. They also like to trash talk after very move...and are viciously aware of the advantages and disadvantages of their contrasting physiques.
