Everyone Wants Incest

Looking through Reddits Dirtypenpals subreddit, I'm continually surprised by the number of people interested in roleplaying incest.

I took a Vampire Fiction class at UCLA as an undergrad.  My professor said that nothing loses the public interest like vampires.  I disagree.  Nothing loses the public interest like incest.  

People just don't want to admit it.

The intense taboo of incest (sometimes I think it's the strongest) makes breaking it much more exciting.  But I think it's more than that.  It's about the forbidden, but it's also about generating sexual pleasure from those people in your life that know you better than anyone.  Family ties are among the strongest bonds we will ever experience.  Even if the experiences are negative, some bonds will remain in spite of our efforts to break them.  

It's a tantalizing thought: those people who know you emotionally, who have watched you grow up might also be able to sexually satisfy you better than anyone else.  Perhaps the familial connection would also create the most lasting, loving romantic relationship of your life.
