The top in this scene is Zak Spears, one of porn's true legends. He had a twenty-year career in flesh films.
The movie here was made early in his career in 1994, when he was in his late twenties and already quite woofy.
The film's title is Boot Black, but I don't know who the bottom is and couldn't find him identified in any listings online. If you can identify him, please shout out in the comments.
