My dad never told me that it was going to be my mother-in-law. He just told me 8 months ago that he met this beautiful woman and she had a daughter. So I was like great im just a lonely child and need a sister. But when I got to met her, the three of us (my girlfriend,her mother, and I) were shocked when we saw each other. So my dad told me to sacrifice my 8 month relationship for his happiness, I was shocked and I told him no and so he said "Alright then, if you don't want to listen then that's fine, I'll send you back with your mom" plus " Oh guess what, son. We got us a house for the 4 of us now Nadia's going to be your step sister." I threw myself on the floor, pounding it and kicking my feet tandrum style "No this is unfair! You can't be serious, dad! Why did you had to marry my girlfriend's mom!? I thought you cared about my happiness!!!" his response was "Get up you baby! I had to find myself a wife, your like 17 and acting like a little kid! Besides, look at it on the bright side, you get to have a 2 sisters!" But this is so crazy dad!" and blah blah blah my dad lectured me about families.
I'm in love with my girlfriend Nadia but as soon as she heard the news that we're step siblings she smiled and told me "Now that we're siblings, you can "play" with me anytime you want plus we get to have the house to ourselves when our parents are working." Oh god this is so embarrassing, it will look totally awkward me and my new step sis holding hands and kissing in school. Is it wrong though that i dated my girlfriend before she became my step sis?
