First off, HeavyKnockers is not concerned with exclusive content. There are 30 videos available now and they're pillaged from various other sources. Also, they rotate the content, so it's the same as what has been there for a couple of years. Don't be fooled by the date stamps on each scene.
In general, for me, the whole exclusivity thing isn't always a huge issue when the action is downloadable. In the case of this site that is mostly true. The videos are divided into clips and can't be saved as full-length files. The streaming button doesn't actually start a stream, but rather starts a download to be watched later.
The videos feature gorgeous huge-titted honeys. As promised, you'll see large boobs heaving and shaking in all kinds of hardcore action scenes. The scenes are generally entertaining and most of the videos are average quality. Scenes cover the three basic hardcore activities: blowjobs, straight fucking and anal sex. That's kind of it for the big boobs. There is no model index or big-cup related features of any kind.
Once you get to the huge picture section of the site, you'll find thousands of hardore photo galleries featuring all kinds of different babes with different cup sizes, both small and large. That doesn't mean there aren't some well-endowed women in the pictures, but it is better to think of this section as just general hardcore photos that are available network-wide rather than main content.
The two bonus sections provide members with a few streaming video sites and eight bonus sites, including Kinky Lesbo, Jerk Him Off and Chica BonBon.
So, there you have it. Heavy Knockers has a tiny collection of videos and a big selection of unrelated photos. The standard price is a little high considering what you get. Gluttons for new, exclusive high-quality big-boob action will only be mildly satisfied here.
