I am sure this isn't rare, some societies accept this stuff.
even in societies that don't, I think incest happens more often than is realized . you only ever hear about the molestation cases. nobody ever hears about the happy incestuous couples who keep their affair a secret
Yep. Did it when I was younger with a cousin. Who is now married with kids of her own.
Shit happens sometimes, it's not something I'd want now as an adult, but still.
