In NAME_1's style, tell the story of a long, erotic, nude sexfight (first to cum loses) near a river. One is a white American writer who is 45yo 5'11" 180lbs with a 7" cock, a belly, an intelligent mien, full red hair, dark eyes, fair skin and a thick beard. The other is a Chinese woman who is 41yo 5'4" 120lbs with tan skin, long black hair and 34b breasts. Describe the setting, motivation, stats (height/weight), ages, asses, amounts of pubic hair, different body types. The fight goes back and forth for a very long time, beginning with a violent, hateful kiss of unbelievable length. Each twist and turn should be elaborately described. Both 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. The loser is the one who cums first. Neither wants to cum. They want to make the other cum, as a show of dominance.
