They dont get along beacause...

...Emilia was always jealous of Carrie

As long as You and Carrie Have been a thing, which was quite some time by now, Emilia didnt think much of your relationsship. Emilia and you made out at some college parties back in the day, but it was never anything serious. As far as you know, she had some relationships on her own, but none that lasted longer than a couple of months. She never liked her step-sister getting what Both of them wanted...You.

After a couple arkward moments on birthdays and family meetings, the two of them began to avoid each other, and thats how they remained...until now.

You look down on your Girlfriend, kneeling in front of you, your cum covering her face, and wonder how she is going to react to your wish.
