There is a whole series actually. So the second couple end up having an entire book and so do others.

The series is with or without. The first book it Without Reservations. The second book is With Caution. The third book is With Abandon
I just finished reading the novel which has 230 pages and I have to say, IT WAS AWESOME! It was a very very fun read.

A few spoilers: I can't tell all the spoilers cuz the story is hella long.
- They get together, obviously, and it was sexy af!
- they reversed positions one time
- Chay's father is awesome! And eventually also the mother accepts them as well
- There's a second couple but didn't have that much story, I would have wanted to read more about them
- Chay and Keaton's parents plus the pack are too good to be true. They're so accepting. Not much familial angst-drama shit going on so it's good!
