I'm a bit late to the party when it comes to......whatever this discussion was, but they don't use stepcest in porn due to legal reasons. Stepcest exists almost entirely due to the fact that payment processors don't want to work with incest content. It's the same reason why characters can't be portrayed as drunk in porn anymore, for an example
Incest porn between actors that aren't blood related in real life is not illegal and in many stepcest videos you will see that the director's true intention was to make an incest story video, for example due to the way they sometimes pick actors who look similar in certain things, have the same color of hair or are the same race etc
