And Baby makes Six

Sequel to Day of Reckoning, so read that first. Two years have passed since the birth of Stiles and Derek's pups, and Stiles is once again pregnant. It's hard to tell who is looking forward to the new arrival the most, Stiles, Derek, their five two year olds, or the rest of the pack. A/B/O verse, mpreg, and graphic childbirth, you have been warned. Disclaimer: I own nothing.
