Wracking my brains for an old Ranma fic

[Bob Schroeck]

I'm not so much interested in finding it again (except to confirm) as much as just stopping my brain from trying to remember it. What makes it frustrating
is that I'm not remembering the main action, just that in a B-plot Kasumi and Kodachi end up in a domme-sub relationship, and that just when the other
characters think they have finally gotten used to the idea, K&K renew the WTF factor by revealing that they switch roles every once in a while.

Does that sound familiar to anyone?

Thanks.
