I must confess that it's hard for me to believe the incest fantasies on here, i.e. I wish I can fuck my daughter, sister, dad, mom, brother, because we are biologically wired to not be attracted to our parents, children, siblings. For survival of the species, we need genetic diversification.
I mean, even in a blind test where subjects are exposed to the scent of a dozen people, the subjects consistently rated family members the least attractive, even though it was a blind test. That's cause our sweat contains steroid Androsterone, which give clues to our MHC gene, the gene in our DNA that says what diseases our immune system is equip to fight.
Even if you're not related, there's something called the Westermarck effect, which is a phenomenon which people who live with each other during the first few years of their lives become desensitized to later sexual attraction.
I suppose those on Motherless are exceptions to the rule. I consider guys posting pictures of their sisters or daughters is more of a mischievious act than true attraction. Keep posting though!
