Incest still IS a taboo topic that's frowned upon in many countries for a logical reason, no matter how 'legal' it may be in some of these countries around the world.
Here and
here are two stats of the states where it's legal or illegal, but mind you, marriage between close relatives and, by extension, procreation IS strictly prohibited for obvious reasons.
I never said young(er) girls or women (our Sarah isn't exactly a young
girl anymore, if we're being honest) don't or never have had sexual relations with older men or male relatives. Hell, incest is everywhere, even in the Bible or in some fucking children's books, ffs, not just in fictional porn, real porn and some shitty movies, but I don't think all these older men we talking about were broke ass nobodies like this Peter guy, just like I don't think the girls doing this were and still are as attractive as Sarah is, at least, not in these modern times.
Anyway, the point I was trying to make is that you won't see this be a common thing in a lot of those countries, despite all the fucked-up shit some ppl might be doing behind closed doors, and a very attractive young woman nowadays refusing other attractive and/or successful younger men for her creepy, old uncle does sound a lot like bullshit to me for a lot of reasons, social stigma being one of them, especially with the glorification of prostitution through OnlyFans, social media and the entertainment industry itself, but who knows, I might be wrong about it, tho no matter how legal and common it may be in some places, it still doesn't make it any less disturbing and disgusting than a normal, healthy relationship between a man and a woman, in my humble opinion. It's one of the many reasons why I said fiction is harmless fiction for a reason and it shouldn't be taken too seriously.
