I believe the initial round was from an email discussion of fic in progress that required some thought as to Revy's panties. But the second round of Black Lagoon characters' undies went on here.

(Oh, Cho, and you may be amused by this -- the incoming resin hunk with the Doku-ish physique? Right now there's only one commercially-available style of undies sized to fit the huge E.I.D. guys -- stretchy boxer-briefs. *giggles*)
