Oszukana siostra przyrodnia

Hello, stepbrother.

Yay. You've been walking around pretty happy, haven't you?

It's 'cause of that new girlfriend you've got.

I wouldn't have imagined that my stepbrother, being as awkward as you are, would get one of my hot girlfriends to date him.

I bet you feel pretty confident now that you have a girlfriend. I know you've always wanted one.
