I Know That Girl - iknowthatgirl.com

pornhub premium screenshot
User Rating:

I Know That Girl is a site in the Mofos network, that features reality-porn style videos of amateur (and some big-name star) girls in intimate encounters with their boyfriends. Shot more in a gonzo/reality style, with the male performer doing the camera work, it can be a very convincing, near-POV experience. Some of this is fantasy, of course, but like most porn, it sells the fantasy well. The site can be viewed directly, or through the Mofos.com domain, which includes all videos from the Mofos network of sites.

I Know That Girl belongs to Mofos, which is currently owned by MindGeek, formerly known as Manwin, the single largest conglomerate of adult sites and production studios in the world.

I Know That Girl Content

I Know That Girl contains nearly 500 videos, starring almost as many female performers. They all fit the overall theme of the site, looking like real, though professionally shot, encounters between the female performers and their male performer “boyfriends”. Newer videos are in HD, though some older videos (dating to the site’s founding in 2011) may not be in HD. Updates occur about once per week or a little less frequently, though at least 1 site in the Mofos network gets updated daily.

The Mofos network is a collection of video sites. Currently, 15 original sites and 5 original video series’ are active, including I Know That Girl, along with access to 6 of their older sites that are no longer receiving new content. Additionally, a subscription provides access to 24 other video sites as a “bonus”. The newer videos all seem to be HD, though older videos may not be. The site does not include helpful HD tags or filtering, so it’s very difficult to tell. Videos vary in length, though most seem to be 25 to 45 minutes.

As of this writing, there are approximately 3500 videos on the network as a whole, not including content available from the bonus sites, since they are not strictly-speaking part of the Mofos network. They also list Live Shows on their site navigation, though those seem to have been monthly events in the past and are much rarer at present.

I Know That Girl Categories

I Know That Girl is almost exclusively male/female hardcore videos, mostly portraying realistic sexual encounters between lovers, though sometimes with a wicked twist – such as a daughter and her stepfather, as the “stepparent” genre is very big these days across most categories of porn. Some videos are threesomes, though that is a minority of the content. They do not have specific search or category functionality on the site itself, but those options are available through the Mofos main site.

The sites and series in the Mofos network are all loosely reality-based rather than highly-scripted. They include themed content from each site, such as Girls Gone Pink (Lesbian), Share My BF (FMF Threesomes), I Know That Girl (Reality), Public Pickups (Public), and She’s a Freak (Solo Anal, Fisting, Squirting, and more). In total, 21 sites active and archived, and 5 original series are available.

The content overall encompasses most of the mainstream porn categories of typical video sites, including Anal, Asian, Big Ass, Bit Tits, various hair colors, Lesbian, MILF, Petite, POV, Public, Solo, Shower, Teen, Threesome, and more.

Videos can be sorted by originating site, accessed via a search box, browsed by categories, and sorted by qualities like top rated, recently added, or most viewed.

The content is primarily hetero male oriented, featuring hetero pairings, threesomes, solo girl, and lesbian content. There is no transsexual, solo male, or gay content on this network.

Star Power

I Know That Girl, sometimes abbreviated to IKTG, like Mofos as a whole, contains a mix of amateur and professional porn stars. It largely gravitates toward amateur or mostly unknowns, but there are a number of big-name stars that have done videos here as well. For I Know That Girl, there are close to 450 models for the site, with a few big names in the top 20 by popularity, including Alina Lopez, Abella Danger, Megan Rain, Mia Malkova, Marley Brinx, Janice Griffith, Kenzie Reeves, Renna Ryann, and Adriana Chechik.

Currently, there are over 2,100 girls listed as models for the network overall, across a broad range of body types and ethnic diversities. The majority of their top 20 stars (as determined by user ratings) are all amateur or lesser-known starlets, with some professionals mixed in.


The Mofos network contains 21 sites – 15 active and 6 archive, in addition to 5 original series. A subscription also provides access to 24 bonus sites outside the scope of original Mofos content. As with many networks, the Mofos.com domain is the top level site, and contains access to all the videos from the network sites. Many of the network sites themselves aren’t directly accessible, or exist in name only to categorize the videos, so Mofos is the place to be for all the content.

Mofos is owned by MindGeek, based in Montreal, Quebec, Canada, with satellite offices in the US in Los Angeles, Houston, and Miami. Though this international parent company owns many sites and networks, they are independently managed and content remains exclusive, as do subscriptions.


I Know That Girl is accessible via a Mofos network subscription. Mofos is a pay network, with subscriptions that allow access to all 21 network sites, original series, and bonus sites. Video previews are available for free with no account, but that’s hardly worth wasting time on – the real good stuff is available by subscription.

Like many MindGeek sites, in addition to paying by credit card or paper check, you are able to pay for your subscription by trading in unused merchant gift cards from about 50 major brands, which is a nice feature, especially for those who are concerned about credit card fraud, or have significant others with access to the credit card statement.

Porn Explosion Advice: The annual membership is where it’s at for savings. It’s worth pointing out that it’s about $30/year cheaper than most other annual subscriptions to MindGeek-owned sites, so it’s a damn good deal for the thousands of hours of content available on the network, and the quality content on I Know That Girl.

We always recommend signing up for trials with a Visa, Amex, or MasterCard gift card, with a small balance, in case you have trouble cancelling or forget to cancel before the auto-renewal.
