What a nice niece

The guy wrote in a forum that in his family women has kids early. It all started with his grand-mother at 16, then his mother at 18 and now his niece with 19. The difference here is that no one in the family knows that the father is the guy, her uncle (her mother youngest brother). For now they are ok, living 2000 Km away gives them some time to prepare the family, but for how long?...
