What was lacking in the main show, was shown here. Like I said in my Kanokon review: I watched it mainly for the ecchi scenes and boobs, but I didn't actually get to see much nudity. So the Specials gave me what I wanted to see. And I'm thankful for that. The story is almost totally absent. Kanokon Specials, basically, consists of 12 minisodes, with the average length of two minutes, and they contain short segments filled with eroticism. One of them, for instance, has Chizuru picking a Valentine Day's gift for Kouta, the other features mostly static images, and some other minisodes feature other characters, suchas Asahina or the twins, in provocative poses and situations.

Yout get the gist: this is just pure fanservice, made for those who were unsatisfied by the amount of boobs in Kanokon. Being one of them, I liked this, even more than the show itself. On the other hand, if you didn't like Kanokon and don't care about ecchi scenes and nudity in it, you won't miss anything by avoiding this.
