The story of a young woman getting into the porn business. She's hesitant at first, but in the end she "opens up," in a manner of speaking.

For you futanari fans, this is the original source of Azuki Kurenai's "Darkness," which is at the end of the manga. Who would have thought nuns could be so, I don't know, special?
