Alright, so about as much time as the DMV or the doctor's office. Except I'll be in line because I want to, not because I'm forced to. I've got a book, so I'll just kick back until it's my turn. As I have seen from numerous hentai doujinshi, Rangiku and Yoruichi are hardy women who can last that long and then some.
My two favorite Bleach females giving Urahara quite a show. Those two are also the most aggressive in their fan service attacks. Coincidence? I think not. As for Urahara, nice work if you can get it, and where can I get it? (I know, I know--get in line!)
