It has a LOT of stories, most are even true, there are MANY incest members on there, and one of them..."incestmom" has 2 daughters with her son, and she's & her son are doing the oldest daughter. XP
In retort to any other comments, I have no relation to the posts on there, nor have I done anything with incest, now, do I think incest is okay....yes, I do as long is isn't forced upon, or like in incestmom's case, she is only teaching her daughter about incest...That is all.
