Well if Brothers or SIBLINGS only account for 40% who does the other 60%?This is some guy eyeballing anecdotes on a public forum, it's not even close to a reliable source.
I don't see anything here confirming fathers abuse more often than brothers, though you might be right, I just seem to remember reading something to that effect.
Isn't 60% more than 40%?
And those are ONLY stats from ABUSE...Not a single one covers consensual.
Which is much more common than the abuse it's just that no one bothers to collect those stats since they can't make a political and social soapbox out of it.
I bet you are one of those that thinks ALL Incest is abuse which puts you right in line with DS' thinking which is why this game is nothing but pure slime and very little seduction.
