At her job
 

I've seen a few of these Japanese office scenes but don't know where they come from (sorry, not large either). And being a mechanic is a dirty job that just ruins your clothes.

Partial Answer
 

The second picture is a vid cap from some series though the web site it is on escapes me at the moment. That same girl walks around an auto shop without any clothes on with the men there giving a running commentary. I have only seen bits of it however as it is a pay site.

thanks a lot..t

I know which one you're talking about. With the host "Special K". I can't tell if those are real or staged, but supposedly she convinces girls on the street to go naked in public and flash. I think the site goes by a bunch of different names.
