I wonder if this might answer your question. Hopefully, it will.

Sorry if this is a stupid question, but what does "inb4" mean?
Also i have a little sis to, but i still fap to it because if the the characters look nothing like me and her then its perfectly fine to me.

I -think- it means posting before whatever follows the inb4. As in "In before _____"

"inb4 impending shitstorm"

Posting before shit hits the fan.

As for me, it's not so much the incest itself (though I do find it...so great), but rather the sense of the forbidden relationship.

I also like teacher/student and things like that. As far as incest goes though, I'm more bro/sis or cousins rather than mom/son or father/daughter. The connection just feels...too direct.

I do find it funny though when a guy is sticking it to his mom then evil smiling like it's something to be proud of. Like everyone is totally jealous that they aren't shtupping their moms also.

well, I never thought about it that way. Could be, because i dont have any little sisters, or a hot mom or something xd
But I really enjoy these neglected (step)mother, or little and elder sister stories~
We may like it because it is not well seen in society. But as long as it stays in the manga, where's the problem?

Good solution indeed. Either man up and break social conventions or keep your distance from taboos. Glad I don't have to worry.
