For a site that has so many different types of stories, I'm surprised that there are so many closed minded people here.
I mean if you believe the story is a fake then why comment on it, just consider it an interactive fanfict story and move on.
Those who think that this "fake story" will just persuades people to accept it as acceptable behavior, there are incest stories almost everywhere. And usually the "most read" section in any sex stories sites is the incest section. "Taboo" the movie is one of the biggest sellers in the porn industry. So seriously, if someone was looking to persuade themselves that incest was "acceptable", they can find it almost anywhere.
But say they did use this story as their template, wouldn't it be better if they emulated the gentleness and consenting aspects of this story?
And if this story is true, why knock it then? The son is 18 and legally allowed to make his own decisions. He could if he wanted to all of a sudden decide he likes wearing stocking, want anal from cute male models and decide to get his dick chopped off and it would be his right to do so.
As we all should understand incest does happen in real life. Supposedly more than most people care to admit. We usually hear about the abuse and violent cases, that's because it's harder hiding physical and emotional scars, than kisses between family members. Most people involved in consenting incest relationships realize that it has to be kept a secret, because so many people disapprove.
It was a cute story, and if it is real, I wish them the best.
