My long affair is about to be exposed as my 16 yr old daughter from my marriage became friends with my 17 yr old daughter from my affair. They're almost identical and there's been talk about ancestry DNA. Nice to have them both in the house though.
@fesshole Wait, how it could even get to this stage? Once your second daughter meets your first one and realizes who you are, you're busted on the spot: "Dad, what are you doing in my new friend's house and why she also refers to you as father?"
