The fun thing is that this is not the thing of someone who like to be the only male in the tale AND it's not the thing of us who like MMF sex... Because, you know, most of male audience like one-dick-only situations, than there are us: a smaller percentage of male audience who like MMF... But for us to enjoy the situation the other male must be *another* dude... We like the complicity with another man and we like females which are into MMF ...This used to be one of my favorite games, but then there was that terrible update where the MC was duplicated and we had to watch every girl get double-dicked one after another with no choices (and if that's your thing, that's fine. It's definitely not mine and I did not see that coming). Did they make any changes to that or at least make the sharing avoidable?
With this unlikely "I clone myself and double fuck my sis without need to share her" you succeeded in the hard task of disappointing both traditionalist males and kinky poly bisexual males...
A lose-lose situation which was hard to achieve without sniffing glue before writing the plot
