3, is I believe the Taylor Lynn scene from Young Ripe Mellons 1 from RLD.

4, is the Fujiko Kano scene from ME luv U long time, also from RLD.

It looks to me that most if not all of the films are probably Red Light District stuff, just going on the style.

I hate these sites, another one stealing studios good product and making money for thier own lazy bastard asses and not giving credit where credit is due. These sites should have to pay out every dime they make to the studios they stole the stuff from.

Anyway sorry I could not ID more.
