Hi
Having seen the following clips:

http://www.xvideos.com/video36798/girls ... in_the_gym
http://youporn.com/watch/2965/man-and-w ... ble-dildo/
I eventually managed to find out that they came from the film Ball-Busting Babes (http://www.egafd.com/films/details.php/id/b0954)
In addition to featuring Laura Lion (credited as Lena), I believe the movie also stars Tera Joy (http://www.egafd.com/actresses/details.php/id/t0139). She is credited as Tereza.
Maybe others can identify the remaining girls in the clips.
Cheers
