Nice try, bro, I almost bought it
There is only one small flaw in your reasoning. These three are not some random group of cuckold, whore and bull from your example. This is Zeke, Keyla and MC. Zeke and MC are best friends, MC doesn't fuck some random hotwife, he fucks his best friend Zeke's wife and his high school ex-girlfriend Keyla. He calls Zeke brother but he fucks his wife behind his back. He fully understands what he is doing and knows that he is hurting his brother.
Don't get me wrong, I personally don't even like Zeke and I have no problem with MC cucking him.
But please don't say that the MC is innocent in this situation and he just lent his dick to some random cock hungry slut.
Keyla doesn't seem to be banging every random guy she meets at the bar. She cheats on Zeke with her high school sweetheart, her MC, whom she still loves, and seems regretting of her quick and impulsive decision to marry Zeke. But instead of clearing things up with Zeke and leaving him if she still loves the MC, she decides to cheat on him. Her decision is as perfect as when she decided to marry him out of the blue.
They both betray Zeke, the MC betrays his bro, Keyla betrays her husband. Although it's not the end of the game, maybe Zeke is all up for an MMF threesome
