#1. About 21Sextreme
This is a free bonus site of the AdultTime network. For more details and insights, see our full review.
Anyone in the mood for exclusive hardcore porn that focuses on different kinks and fetishes will find a mouthwatering collection of scenes and galleries on 21Sextreme and plenty of HD content. Their latest content features older women and men as well.
#2. Content Breakdown by Categories
Welcome to the dark side of the web, or so they say.
#3. First Impressions & User Navigation
Multiple BDSM porn sites love to use the red-on-black theme, and 21Sextreme follows the same logic. I guess it’s the most intense combination. Anyway, at the top, 21Sextreme promises weekly updates of extreme hardcore content but doesn’t mention their site, so they do it carefully. That’s the right approach, as the latest videos seem to indicate that the site has paused its updates. However, as that’s the case with the entire AdultTime network, there are many more videos on the same theme, so the advertisement remains accurate. Then, you follow a typical template with live thumbnails, which are always my favorite. Still, unlike the previously reviewed AllGirlMassage, also part of the same network, they don’t give you any free trailers. That’s a sign of a poor site because why wouldn’t you want your audience to see all the bestselling points?
Since 21 Sextreme is part of the Adult Time network, it has an intuitive interface that makes browsing easy. You have access to various sorting options, including filters, tags, categories, and orientation, but an advanced search feature is not available. Moreover, the platform features custom playlists, favorites, comments, and ratings, and all functions work seamlessly on both mobile devices and computers.
#4. Porn Content & Performers
I’ll point out that 21Sextreme is different from 21Sextury, but that comes as part of the package, too. Apart from a 3-day streaming trial ($2.95), you can opt for the monthly streaming package ($19.95), the monthly streaming and download plan ($29.95), or the 365-day plan ($119.40 per year). Membership also grants you access to the Adult Time Network, which features over 100 channels or sites and more than 56,000 videos.
When it comes to 21Sextreme, the site features thousands of scenes of various lengths, along with the same number of galleries (each containing an average of 120 photos) that are available as ZIP files, ranging from HD to super high-res. The videos support up to 4K playback and streaming with multiple bandwidth options, while downloads are unlimited. Most of the old collection is in SD quality, but you do get hundreds of Full HD videos and around 100 in 4K.
So, what is this 21Sextreme content everyone keeps talking about? It's far less brutal than you’d imagine, based on its name, but ass worship, gapes, butt fucking, double penetration, grannies, European, and things of similar nature appear here. It’s not a KINK.com alternative where they just hammer that pussy like it’s a sponge. Instead, 'peeing,' occasional fisting, and so on, describe it better.
#4a. Update Frequency
There are a few high-res updates per week, but some 21Sextreme sites have stopped updating. Even without the bonus network content, this site provides you with lots of fetish sets and scenes with BDSM, old youthful porn, fisting, trannies, creampies, and so on.
#4b. Pornstars
When you migrate from fluffy hardcore to extreme and nasty porn, the pornstars change too. It’s no longer a library of sugar and strawberries. Nah, because the fruit has rotten, like Bonnie Rotten, ha! But with all that said, 21Sextreme hosts its share of “famous hardcore” sluts that only the most sophisticated viewers will know. There are cute pornstars, decent, and those that resemble a burned pizza. But just for the sake of it, I’ll give you a few names. So, we start with Zuzu Sweet, Nikki Nuttz, and Anna Valentina and finish with a duo of Eyla Moore as well as Lisa Pinelli.
As for guys, and there are lesbian videos too, they are more mainstream because if you fist someone, there are no repercussions for you because you might as well star in a sensual erotica the next day. For females, they like to stick with one thing so there’s no way the same name will appear inside a Playmate sensual video and here.
#5. Conclusion
21Sextreme is appealing even on its own but becomes irresistible when you consider the bonus network access to Adult Time. The only downsides are that its collection has many SD videos and no more updates from this specific product, but Adult Time has many more BDSM sites and makes up for it.
