He can be stepdad to two unrelated guys if he marries one woman already with a son, divorces her (or she dies) and then marries another woman already with a son. As you wrote though, ‘it’s complete fiction’. It’s a fantasy that is titillating to some, which is what porn is for. Is it wrong to be titillated? I can’t be the judge of that. One can be titillated by the fantasy of something and not want the reality of it. It’s complicated, I suppose, for moralists, which I am to a degree. If 2 guys over 18 want to pretend they are stepbrothers in a scene and an adult wants to pretend he is their stepdad and they are acting out a consensual sex scenario, I have no problem. Do I have a problem with real brothers having consensual sex? NO. Do I have a problem with a real dad and son having sex if the son is an adult and it’s consensual? NO again. Non consensual sex and sex between an adult and a child I have a problem with.

Whatever this family’s ‘makeup’ is supposed to be, it certainly is a mixed-up ‘family’.
We can’t but wonder why MEN wanted this to be a ‘family’ in the first place. Apart from the fact that every nitwit can see it aint, … what is the message MEN wants to communicate.
Let’s just say … this studio is run by weirdo’s (and not the likable kind).
