Portrait of a student

Hello,
I'm looking for a fiction that I believe was a WIP when I read and would like to see if it's finished. It's all human and a student-teacher fiction. Buffy is a high school student attracted to her teacher William. He tries to resist but fails (surprise). She goes to his home to have him paint her portrait in the nude. Once they get involved sexually, I recall he takes nude photos of her in bed. Does this spark anyone's memory?

I think this is it.

It's still WIP.

In her profile here it says she is posting now at Adultfanfiction.net but the link to the story there is the same amount of chapters.
