Any FFM videos of women competing with one another?

I like watching FFMs, and they're all nice and such, but I can't say I've ever come across one where the women are competing against one another. Say for example the guy is fucking one of the women and the other starts to get jealous, or start dirty talking about how her pussy is so much tighter than the other woman's, etc. Just little things like that. Can anyone help me out?
