I've been thinking about the steady increase of porno involving siblings, parents, or some sort of parental substitute (sexy teacher, lascivious nanny, etc). I'm convinced that this is the result of further atomization under capitalism. As social relations and active participation in community continue to degrade, essentially the only people you will have any sort of meaningful connection to will be your immediate family.
If you're lucky you picked up some friends at school and got along well with your co-workers, but it's very likely that you have no emotional ties or experienced any sort of physicality with anybody outside of who you grew up with. Of course you're going to end up horny for Daddy when everyone outside of the nuclear family is basically an alien that you're incapable of feeling any sort of connection to.
Somebody's probably thought about this more than I have, but I don't feel like I'm off-base in saying that incest increases in popularity as everyone's social circles continue to contract. Or maybe Freud was right and people have always wanted to fuck their moms, I don't know.
I'm coming back to this thread to drop this insightful tumblr post I saw the other day:
The poster here is addressing something different from what you're talking about but I think there's something to it; blurring the line between traditionally 'platonic' relationships like mother, sister, and even friend with the 'romantic' roles of boyfriend, wife, etc is certainly something I do with my queer friends. It's not quite the same thing but I think there's something to be said about desiring a relationship with someone that is both close physically and emotionally but yet does not reach the 'level' of 'partner.' I like relationships that are as close and reliant as the sister but I also like having sex, if you get what I mean.
Yuuup. I'm the "mom" of the group, and we all do feel like a strange little family- to a degree, because we also all hook up sometimes
