Amateur Dump is a source of free porn pictures. It isn't fancy, and you don't get full sets, but you did get a ton of categories to choose from and naked pictures of hot girls that won't cost you any money.
AmateurDump.net has a blog-like design that is self-explanatory when it comes to navigation. There are no bells and whistles here. Simply select the category from the left side of the screen and click to see what it contains. There are clips as well as pictures to choose from. Some of the categories include couples, emo, girlfriend, threesomes, swingers, lesbians, and selfies.
Selecting the MILF/Mature category took me to a large gallery of an older blonde with short hair and natural tits. She modeled several sexy outfits around the house and also did a lot of fucking. Some of the hardcore pics showed her getting plowed hard from behind, and others showed her being double penetrated in a BBG threesome. I was able to download the full gallery to my PC without paying a penny. However, if I clicked on any of the thumbnails, I was taken to another site featuring a completely different photo set.
When I went to view the highest rated set, I was taken to a large gallery of 500+ pictures, featuring a blonde coed, her hot girlfriends, and even some cocks and fucking. In addition to a large number of images, there were also seven videos. I was able to download all of it without issue. Personally, I found a lot of images boring. It looked like someone had uploaded their entire camera roll of candid shots. There was a lot of repetitive bikini pics and shots of people standing around with their clothes on, not doing anything interesting. I would have preferred a smaller set of just the good stuff. I enjoyed the girlfriends all standing together showing their asses, and I really loved the closeup pussy pics.
Amateur Dump has a lot, but it is nothing special. There are better free sites out there, but because of the large content downloads, some people might enjoy taking a peek anyway.
