Stepbrother For Christmas

My dad asked me to spend time with my new stepsister.
But after spending so much time together…I’ve decided that all I want for Christmas is her naked with her legs wrapped around me.
I know, I know this is wrong.
But how can I resist her?
I can’t, I’m obsessed with her.
She’s my Christmas angel—and I’m going to cherish every moment that I have with her.
I’ll just have to figure out the rest later.
Sounds logical, but what if I run out of time?
