Step sister to lover

[mettedu]

My father died when I was 8, now after all these years I hear that my mother is getting married?! I'm 22 now why is she getting married after all this time? Not even told proporly over the phone I got an email, and now there was this girl who was to be my step sister. "I'm just supposed to drop everything and come home?" but being my mothers son I book the flight and head home.
