YMAC Hip Hop Hunks
The only dvd/video where Billy Houston is ever fucked (by Tony Young).
The video appears to be on the web as I've seen thumbnails posted of it showing the scene.

Looks like Etienne - one of his earlier works. It's definitely not Tom of Finland's style.
For examples of his art see http://artistetienne.tumblr.com/

How could you not mention he gets naked in said  movie Son Of A Gun. What a stunner.
