First off, these ideas are by no means fully fleshed out and many things can be hammered out via PM before we get down to the fun stuff.
Spy vs. Spy [Bon][NC-H]
This is sort of like Mr. and Mrs. Smith because it will be two spies forced to work together who may or may not like each other but need to keep up appearances. I'm sort of thinking that they're both dominate personalities and each will take the chance to impose their will on the other person given half a chance.
In this game you would be playing a female who is either stalking or tailing my character. Once I find out that somebodies after me I try to get away but fail. After that we can see how things go.
