- Main niches: Best Paid Porn SitesEuropeanFetish

Today we’re looking at a network of 16 different channels that used to be standalone, and are now part of what might well be the single largest network available in the marketplace, Adult Time. Here you’ll find all kinds of kinky and fetish hardcore porn – from the simple to the very niche, actually, and all with great quality baked into their production standards, model choice, camerawork, and more. Today’s porn site? That’s 21 Sextreme, an offering that’s been growing in popularity for some years now, and rightfully so, since the models are the sexists around, the content is widely varied, and the quality is excellent as well.

Sixteen Channels of Kink and 200+ From The Larger Network

At 21 Sextreme you’ll find 16 different channels or sites to enjoy. This variety of niches starts with deep throating and rough anal, and from there it extends into medical play, speculum fun, seniors with teens, deepthroating, DPs, and even a nice variety of BDSM scenes. Wether you like more standard niches, or prefer the more rough and kinky side of porn, you can quite likely find it here. And that’s just at 21 Sextreme itself. Adult Time’s larger library includes more than 50,000 bonus scenes across hundreds of different niches, and a standard membership to 21 Sextreme gets full bonus access to quite literally all of it. As a result of the quality, which you’ll find detailed below (and on the Adult Time review), added to the sheer, massively impressive size, this is quite arguably one of, if not the, best porn collection available online – and once again, it’s all part of a standard membership to the formerly standalone network 21 Sextreme.

Thousands of Kinky Videos, Regular Updates, 4K Content and Great Galleries

Let’s move on to the details on the library in specific under 21 Sextreme’s umbrella. Across the aforementioned sites, you’ll find more than 4,500 individual videos. New ones drop about twice a month, but you’ll get multiple daily updates across the larger network as a whole if you need new content – a good chunk of it is even kinky. Meanwhile, hundreds of the videos here, and thousands across Adult Time, are available to stream or to download in full 4K, so you can take full advantage of the great screens on most newer devices. Speaking of devices, the site is mobile-responsive too, so you can browse the huge collection in pretty much any device you like. There’s also a gallery with each video at the 21 Sextreme sites too. These are chock full of massively high-resolution shots, averaging about 120 per gallery. They are also available in convenient Zip archives in case you prefer to download them. Remember, though, that downloading on either the videos or the galleries does unfortunately require a reasonably small membership upgrade, or an annual subscription if you prefer.

Great Feature Set and Site Design

This is one of the most feature-complete sites we’ve yet to see in the online porn marketplace. You get a fantastic advanced search, plus an amazing model index. There are favorites, the interface is modern, and properly mobile-responsive, and there are great filters and sorting option too. You can also show or hide a number of different kinds of porn, leave comments, enjoy the active forum, or more. Ultimately, this is one of the easiest sites to use within today’s porn marketplace. That’s not an exaggeration. For more details on site design and features, you should check out the Adult Time full network review, which you’ll be able to read elsewhere on this site.


  1. Great variety of surprisingly kinky fetish hardcore content, spread across 16 different sites/channels to enjoy – and more than 4,500 individual videos worth of it.
  2. More than 50,000 videos across dozens of niches of porn across the larger Adult Time network – still one of, or the, best network currently online in the entire porn marketplace.
  3. Superb, world-class usability on a modern and mobile-responsive site with a long list of great features.


  1. 21 Sextreme doesn’t update very commonly anymore – but this is ameliorated somewhat by the larger network, which is almost constantly dropping new content.

Author Rating


21 Sextreme is one of the best sources of kinkier hardcore (and lesbian too!) content that’s currently available across the online marketplace. The bonus network that it comes with as standard is so large that it can simply replace most porn collections, too – and sufficiently varied, plus it has a laudable site design, feature set, and more. The lack of updates to 21 Sextreme itself, relatively speaking, is the only real downside here, and even that is clearly eased by the often multiple, daily updates on the larger network. I award 21 Sextreme with my full recommendation and a score of 90.5 points.
