I love stories that take the innocent and slowly peck away at them until the downward spiral starts or the innocent then get off by looking for others to corrupt. The use of drugs(cocaine), alcohol, etc... Stories such as "Models and Super Spies" by the Soundandthefury, and the stories "Appleby Blush" and "Palmer" by Hal Tee are the best examples of this corruption of the innocent while at the same time being incredibly well written.
