This is a still from a video. The video is available at http://rawmasculinity.blogspot.com/2013/03/lessons-ii-bb-video-clips.html?zx=fb4a1ad22791318.

The video runs about 2 minutes. It's titled "Lesson no. 4". There are two other video at this link as well. The one I like the most is "Lesson no. 4".
