Actually the fic was born out of a couple of random funny conversations my friend kineko and I were having, the first of which had Naruto in heat and then Kyuubiness and briefly running away and stuff, and then a longer convo about Team Seven and all their agemates going through the building of a new house and then the "yay!new house" party that ensued. It was mostly about funny antics and bits of dialogue, kind of like on-the-fly RPing. Sakura was heavily pregnant, so she wasn't allowed to lift anything or drink alcohol and so she was Very Grumpy. So yeah, Teamwork was always circling around Team Seven's future kid, but it was more about the pregnancy than the kid itself. (I seem to remember we also played a bit with "oh look sakura gave birth, whose kid is it?" moment, but... I've forgotten what we were talking about. Came up with the actual kid myself only a couple of years back. XD; )

Kin was sleeping over that weekend, and there I was on the computer, in the dark room with her on an air mattress and half-awake going "...asuka go to bed." and me going "yeah yeah gimme a minute, I'm taking notes" and the next day I had plus ten pages of the first chapter of Teamwork and minus five hours of sleep.

I didn't know what happened during The Night until... I'm not sure, a year or two after I started writing it. It always started with the morning after. XD; (made the start of the fic kinda wobbly actually... hm.)
