Yarisugi Companion to Atashi Monogatari

I only started reading this because it's by the same guy that did the story and art for Kangoku Gakuen. Just like Gakuen it has great fan service, but unlike Gakuen it has a horrible story. Such a simple and boring story, but the fan service is both enjoyable and hilarious. All in all though, fanservice is the only thing it has. It's short, and might be enjoyable to read if you got some bored spare time.
