Story I once read

[jsword]

I was wondering if any of you could help me find this YoruSoi story I read once. It had a new character named something kinda like Raiken or the like and the new character had used to be a boy. However they turn into a girl and have Soi's child but then gets kidnapped by Arrancar. Yoruichi gets all pouty about the baby. :p

It's a really odd story but it's bugging me that I can't remember it. >:
