bodybuilder mistress fights rich wife (looking for story)

[lifeofriley]

hi unfortunately I don't remember the author or much about this beyond vague concepts but about 10+ years earlier someone posted a catfight story where a man is married to a rich wife but they have a cold relationship. I can't recall much about the wife beyond her being the typical slender rich blond girl I think. he ends up seeing a muscular bodybuilder type woman by chance and they hit it off.

the wife finds out eventually and it leads to a fight between the two and to husband's surprise the wife comes out of the gate in charge of the fight. believe the muscle girl eventually wins but barely. I want to say the wife pulls up in her car as they arrive at or leave a house, there's something with a house door where the rich wife drags the bodybuilder girl inside so she keep on kicking her ass without someone calling the police.  I believe the fight is a mixture of punches and some wrestling, maybe hair pulling too. don't think the story was very long overall maybe average length for here and don't know if the author wrote more stories or a sequel. if anyone knows what this might be and has a name, link, or copy please let me know!
