I would like to try an RP Idea if this is something you find interesting:
ME: A Sex addict and recovering alcoholic (Male) who struggles with his addiction much like a tragic alcoholic. He is a Cop he lost his wife a long time ago in a back story he doesn't like to talk or think about. He had kids or has but doesn't say much about them. Smokes cigs, drinks a lot of coffee and is struggling with his addiction when a married woman is assigned to work a case with him.
You: Sexy and alluring you are also a cop. You have a kink-you like to seduce your partners... to dominate. Your spouse has no idea about your nawty behavior you keep it secret and don't give a thought to your double life, you like to flirt, create the sexual tension. Your new assignment and office is in a small town with this rouge cop who sometimes gets in too trouble is your new partner and seems exciting, shiny and new.
The part of the story I would like us too focus on is the tension between the two, and the struggle.
I am open to completely different characters if these don't appeal- I am more concerned with the Male character struggling against his addiction and the female character who focuses on the prize and moves in on her prey- to break his will and get him to give in. Sexual tension is important here :)
