Boner Tube is an interesting name for a website, but I'm not going to fuss too much over it, because I think the content they have is more important. See, I've linked you directly to the bareback category and boy, let me tell you that these guys know how to share some impressive hardcore fucking that isn't wrapped up! If you want to see boys having natural fun, I fully recommend you pay a visit to Boner Tube.
Once you hit the bareback category, you'll be able to sort content based on number of views, content rating and duration of the clips. New scenes are added on a regular basis and the average length of the scenes is pretty damn good too. I'd say that most of the videos are amateur in nature, but some professional barebacking also crops up from time to time.
So yeah, do yourself a favor if you're down for some bareback fun and check out Boner Tube. These guys have you covered for the type of content you're after.
