K Is For Kink and T is for "That's good Femdom!" It claims to be more than just a porn site and that it bridges the gap between artistic media concepts and eroticism. After taking a look, I noted that it succeeded in its goal.

KIsForKink has some great content, but it's still in the process of growing. There are currently 31 movies spread out over 62 clips, while new clips are getting added three times a week. And these aren't just a minute or two or even five minutes in length, either. Most of them run around 20 and come in two sizes to choose from and both streaming options look great in Flash.
The movies feature some really hot BDSM and hardcore sex, all focusing primarily on the physical, emotional and mental aspects of Femdom. One scene that appealed to the comic geek in me had a sexy Domme playing Catwoman.
She forces her captive Bruce Wayne (aka: Batman) to be her sub, convincing him to give himself to her completely by promising not to hurt his pal, Alfred. After subjecting him to cock and ball torture, it's then revealed that dear old Al was actually her loyal slave from the beginning and loves taking punishments from her. She then dishes out the same kind of pain to him that she just gave Bruce.
Extras include a user forum to discuss your favorite fetishes and suggest future scenes you'd like to see made. There's also a blog that discusses the Femdom role in society, pop culture, etc, but it's primarily used to give quick reviews of new movies and clips. There are no photos on the site.
One notable bonus that surprisingly isn't advertised anywhere outside one of the blog postings is that membership also includes access to F Is For Filth. It's their sister site that focuses on "the darker side of Femdom," including hardcore BDSM and golden showers.

K Is For Kink features well-made and unique content that really makes it worth checking out. If its quality and update frequency stay the same, it's bound to become a prominent Femdom site over time.
