They call it They Didnt Know, but I figure they must have had a least a bit of a clue in some cases. That's mostly because much of the content is too high in quality to have been captured in a truly clandestine manner. Nevertheless, some of the scenarios are realistic enough to get your voyeuristic imagination going about whether they did know or not.
TheyDidntKnow's site design and navigation are all good, but they fall short when it comes to adding content. According to the dates on the most recent updates, it has been almost 10 months since anything new was added. Since our last update they only added six more videos.
There are 45 videos in all and they're available in stellar-quality Windows Media format. However, some scenes are crisp and clear, while others are dimly lit and recorded from a far-away vantage point. Nevertheless, the interior shots of both solo babes masturbating and couples doing it are clearly visible. The outside sex action, especially those filmed at night, are not so easily enjoyed, but more believable.
Each of the episodes includes some still images, so there are 45 galleries. In the situations where the voyeurism seems most believable, such as when someone films a couple doing it at night against a tree in the park, the images are rather blurry. These are definitely vid caps and they're not really worth looking at.
Your membership comes with 22 full-access bonus sites, some of which are high in quality and exclusive, such as Coeds Reality, Police Sex Tapes, Club Real Virgins and Ladies Tricks. They offer loads of amateurs and also throw some reality content into the mix. They Didnt Know gives some super-looking "spy cam" vids, but not enough of them to make it worth it. It is really the bonus sites that will make it worth your money or not.
