Cowboy top

The perfect top starts by having his bottom suck his cock.  Then he eats out his bottom boy (or girl) and gets his bottom moaning with anticipation.  Next he inserts his cock into his bottom and fucks silently while watching his bottom moan, thrash around and cum violently.  Finally the top either unloads in his bottom, or better yet withdraws and soaks his bottom in cum. 

Here are a few stills from "Rough Riders" --- this scene as most of those elements at least.
