Sometimes Revenge Is Best Not Served At All

The brothers of the British Isles and one of their sisters don't exactly like that their sisters have blackmail material and plan to use it without them having some kind of leverage in return. So they hatch a plot for revenge.
However, sometimes it turns out that you should really know your family better, and that your saviors can turn traitors very quick.
The brothers are about to learn far more than they ever wanted too about what a girl's night out is like when it comes to their four sisters, an absurd amount of alcohol, and drinking songs.

Sequel to Sea Shanties And Sober Siblings Don't Mix. I recommend reading that before reading this to get the full experience.
