Hahahaha I don't know where you thought that someone who likes Harem could consider Amanda worthy of being one of the MC's wives, only Erika, maybe MaKani, now Alexis, Amanda can only be part of the MC's pack since they are bitches in heat, like good sluts they have to be used but not valued.
Harem MMC or a reverse Harem FMC, and everyone with a loving relationship with the MC owner without maintaining a relationship with outsiders, can share within the harem, but not to disrespect or the Cuckold's climate, the members of the harem are more or less balanced, You can't say Chloe has a Harem Loke, Derek, Koa and Pau and their gang do not have an exclusive relationship with her, and it is not respectful and harmonious between them, this is part of the fetish and the "Harem fantasy"
But Amanda has always made it clear that she dated other guys, so there's no point accusing her, and she doesn't have a relationship beyond a friends-with-benefits relationship with the couple. Not every girl Loke has sex with becomes part of his harem like Chloe does. But Amanda could have better taste, like it's not about looks, but personality. Even Guiseppe would be a better partner for Greg.
Speaking of Greg, when are we going to fuck Ema in front of him, although I don't think he'd mind. And I don't think she's ugly; she's still a turn-on.
