The big dicked guy is Billy Jay (http://gayeroticvideoindex.com/S/8/34748.html) and the other guy is Jack Roys (http://gayeroticvideoindex.com/S/3/33333.html). This scene was originally part of a Czech porn movie from probably 7 or 8 years ago. Don't recall the name. However, the scene was remastered and released by Staxus fairly recently. It's a pretty hot scene.
