429 Videos has a number of sites on their network that I think are worth mentioning. This one goes by the title of Ripped BF Videos and as a bit of a gym junky, I can say that it's a great place to find guys that are ripped, hung and looking for some fun. That's right - a gay amateur site that focuses on strong buff studs - what could be better than that?
The archive here has a few hundred videos for you to check out and all of them appear to be 100% amateur. There are regular updates of fresh material too, so if you like a steady stream of hot ripped jocks on a site that you decide to join, Ripped BF Videos might very well be the best destination for exactly that.
Note that there are no download limits or DRM restrictions here at Ripped BF Videos and you'll also get free bonus access to a bunch of bonus sites that feature similar amateur productions. The trial sucks though, so if you want to check this place out I recommend signing up for the full site straight away.
