The Baker Street Dozen

Sherlock and John have both been ignoring John's heats, not acknowledging they'd both like to spend them together. But when John's heat comes early and Sherlock has to come back to the flat, the world shifts and they find themselves bonded with pups on the way, and must learn to adjust to life as a bonded couple trying to prepare for the birth of their babies. They meet with many different challenges along the way, having to deal with the reactions of others - and what happens when Moriarty takes an interest? Lots of fluff. Like seriously there's loads. And there's a bit of angst/danger/getting things wrong too but mostly fluff and lots of sex :D
