The mod "simply" adds breathing motion to 26 of Bethesda's original idle animations. You can choose between strong and subtile breathing.
Although these animations are intended as an option to the http://tesnexus.com/downloads/file.php?id=35551, they work as well for males and all non-BBBed female characters (BBB = Better Bouncing briasts)
The video shows 2 (out of 6) different versions of the animations.
