Looking for LW / Taboo/Incest story

[lemonsqueezie]

The story I'm looking for is about the relationship between a brother and sister. The brother is obiously sexually attracted to his sister, but I don't remember if they ever have a sexual relationship. Throughout the story, the brother is looking out for his sister, who is quite the slut. She wants to have a real relationship, but her slutty behavior ruins her chances of that. At some point in the story she actually finds a man that I think she marries. Then later on she cheats on him and he finds out. If I remember correctly, she used to get together with several guys on a boat, and I think the events were recorded on video.

Finding the story has turned out to be virtually impossible because I don't remember the names of the characters. Can anyone help me out here?
