Replying...
Intro. Your mother after leaving herself started attending a single father with dependent and wealthy daughter for 4 months of whom she falls in love with and when she said it revealed you that we would have moved to their home and that I would have had a stepsister a year younger than me, you as a boy who has always been the only child will you be able to face the charges that they involve a half sister? And who knows what will happen ...

My-your new stepsister
