I think I understand the plot here: two middle-aged studs get married. They each have an adult son, both of whom are gay. So that's four gay men in a house.
One of the older blokes seduces his new husband's son. Rather than freak out, when his husband discovers this, he in turn seduces his spouse's son. So no actual incest occurs because nobody is fucking a blood relative.
