Again short story so spoilers ahead. This one is like only 20 something pages.
Anyways...
This newly met and mated alpha/alpha/omega trio have now moved onto the next day? Maybe? Who knows but the alphas have to take turns hunting demons while Tristan is still in heat.
One gets hurt and the omega heals him.
Then they decide to start spanking the omega, there is some dp (which wow, he was a virgin yesterday), and they become more connected.
Then the book ends.
I wish I knew more about the demon hunters, they sound cool.
