An addition to the Kanokon series of anime, and is perhaps the closest the series ever comes to reaching hentai levels of sexuality. If there wasn't enough nudity in the first twelve episodes for you, the majority of these severa-minute long specials will have a fair amount of breasts, nipples, and ass.
There isn't so much a story in these, as the occasional special does have an idea behind it (be it what to get the main character for christmas, or how to best show their love at valentine) but these are more 'one-shot' ideas tailored towards the erotic. These are spliced in with the occasional (read this on another reviewers description, but it does describe it perfectly) 'photoshoot' episode, featuring stills of characters, or the occasional bit of actual animation, and can range from them in clothes, to them in a bath.
Whereas most of the characters in the original anime series stayed fully clothed (or underwear/swimsuits at least) this gives the supporting cast a chance to strip off for the viewer, and in some regards, the fact that that happens is quite nice (as in, the nudity isn't JUST reserved for the main characters).
There is a little animation, short episode/one-shots, and is the same quality of animation as in the originals, and the same is with the sound and characters.
If you're looking for something just to pass the time (or had a crush on one of the minor characters and want to see them bear all, and use this as 'material' for certain activities) then this will be right up your street, but it is not needed, and probably will be hated by a fair number of people because of it's pandering to the 'male' audience (because of course, females don't like to see females get undressed, do they?)
