@zzc: There is and its still femdom really just with a girl instead of the guy, most people miss it when its there cause they just see lesbians playing around in their heads over what is really going on in the pic(s) in question.
Next time you are surfing around for lesbian stuff look for ones where one of the girls is collared and/or tied down and then try to find the deeper darker stuff from there.
Its not my cup of tea other wise i would point to the http://www.kinkpayperview.com/ website for that stuff, they do have free clips there and no i'm not affiliated with them but its a start for places to look up various BDSM stuff.
