Established B/J w/ twin girls

[solarisday.livejournal.com]

Hi, I'm looking for a specific B/J story, and I hope that the few details I remember will jog someone's memory as I've forgotten both the title and author of the story. B/J are in an established relationship. I believe they're living at Britin. They have twin infant daughters that were born via surrogate. It's a future fic, because an older Molly visits to babysit, and spies, through a window, B/J ... ahem ... cavorting on the hood of their car (I think). The story is several chapters long. And it's sugary and sweet and just what I'm in the mood for right now, so I'm hoping somebody will be able to use the admittedly very few details I've managed to scrape together to point me in the right direction. Thanks very much, in advance.
