Looking for a old Story

I have been away for some time and now I am back looking and re-discovering this world.
So to this end I have been re-reading some stories and posting in different forums, but there is on story I have read and I can’t reminder the name or were I read it. So hopefully someone out there might be able to help.

What I can reminder is that it is a Female Dom Student and a freshman female student whom meet on a beach, and the relationship starts.
The Female Dom is on to making films for a BDSM filming company, but due to the fact that she has money and comes from a wealthy family, she wears a mask.
Were as the female sub comes from humble backgrounds.

During the story, a Dom Man is introduce and the relationship between the two Doms go into a loving relationship,
There is a contract draw up also I think for a mouth to give total control of the sub


if you have read this then please let me know.
thanks
