A good site where you can find free amateur porn is fapd.com. There is quite a lot of content uploaded every day, and some of it is exclusive as everything is uploaded by the people who visit the site. The site has a nice simple and easy to navigate design, so finding whatever kink turns you on is an easy task. One downside of the site is that there are a couple of pop-ups that you cannot avoid, and there are some ads in the player.
Besides the small ads when you pause the video, the player fapd.com is using is quite good as it streams without any interruptions. Overall, if you are a fan of real amateur porn videos, then you should definitely give this site a look as it might surprise you with the content that it offers.
