This is a post i found on a forum and thought it would be interesting to share as it underlined the opinions i already had about the disgusting pseudo-incest stuff that has been spreading over the last years. I don't agree with some of the conclusions, mainly with "it's just fantasy so it doesn't matter" as being a good argument. It obviously does matter, even if it's "just" fantasy. If you have pedophilic fantasies it's definitely a VERY big problem, even if they remain a fantasy your entire life. I'd like to add that it's not just "step-x stuff", it's actual incest stuff because during the action they refer to themselves as "son", "mommy" etc DIRECTLY, they "skip" the "step" part many times.
I agree @ultrafabber, but I am a little surprised that the quotation you have included only relates to sexual relationships between step-children or step-children and their step-parents. There's a lot of content where full blood incest is portrayed. On the rationalization that is mentioned, "nobody watches porn for the story", that is bullshit! For me and countless people I have spoken to on these forums, the story is everything! When we are still caught up in this addiction and looking for instant sexual gratification, we are searching for the "perfect" video. That doesn't relate to a sexual position. That is primarily to do with the set up of the video: the premise, if you like, within which the sex will take place. Incest is attracting large number of viewers, in my opinion, because it is an example of the "forbidden fruit". The more wrong it is, the more dopamine is released. It is sick, but that is how porn addiction works.
Sexual abuse of step children by step parents is much more common than full blood incest (unless memes about sweet home Alabama are true). This kind of porn may help people with rationalising all kind of creepy and horroble things they do.
It's all "step incest" but they always call each other mum/dad/sis/bro etc. I don't have any step relatives but from my friends I know they don't call them mum/dad/sis/bro etc They always use their name. I wonder if its supply and demand or if porn makers are purposefully trying to get people into more sick things.
