Why is imouto incest such a popular fetish?

Onee-sans are better

>>146245820
it's only popular amongst autists who have no 3d sisters

i guess they like the idea of being close to a female without putting effort into building a relationship like you'd normally do with someone you're interested in

Hahaha you naive fool.

Regardless of whether you have a sister or not, imouto incest is an erotic act. Perhaps it's because it's taboo or perhaps it's the familiarity with the one you grew up with but whichever way it's portrayed it's pretty hot. Unless it's not.

I have a real sister though.

Is repulsive

You must be an extreme autist.
Unless your sister is hot. Post pics.

Please go back to your contamination threads with likewise degenerates.

Pretty funny how her slit is showing through while you can't see something so incredibly tame compared that are her breasts.
If this was loli, the animators would already be sitting in jail.

>mother incest is only popular among people who do not have 3d mother
This is how retarded you sound.

>>146248660
True, though we must add that people into mother incest are the lowest kind of scum, no wonder the insul "mother fucker" comes from that sickness.

>>146248660
I've had a good time with mother son manga and am not sexually attracted to my own mother, I can only imagine it would be the same if I had a sister.

>>146248733
I doubt most people who like mother incest feel the same for their true mother. Same goes for sibling incest.

>>146248964
Yes, I can confirm.

>>146249067
It doesn't only related to your own mother.
If you are attracted to women who are already "past their prime" and given birth to someone's child, you would have been considered one of the lowest "mother fucker" scum back a century ago.

I find onee-sans more appealing. You know, the ones that go "ara ara~".

Yeah, bad taste. >>146248552
