Those Salted Caramel Hot Chocolate Blues

This story was submitted for the Strictly Dramione Secret Santa Fic Exchange 2017. Poor, pregnant Hermione is on bedrest and has a craving for the perfect salted caramel hot chocolate. Sadly, every one that Draco has brought so far has been wrong for some reason or another, but he's determined to get this right for her. Rated M for coarse language. One-shot.
