Wet the Beginning features a pretty clueless female protagonist.
I have minor issues with using the term "corruption" in these games. Corruption implies moral decline, when generally what happens is that the characters become more sexually uninhibited, potentially to the point of sheer depravity. But they're not corrupted into committing murder, robbing banks, etc. I guess if they're corrupted into committing incest, bestiality, adultery, prostituting themselves or a friend/family member, assisting in the corruption of others, etc., maybe the term is more appropriate to my way of thinking. I guess it's hard to think of an alternative term.
