Bloodrayne (vampiric, dom-sub, F/F or M/F)

[ff]

I’d like to RP as vampiric femme fatale Rayne, from the Bloodrayne franchise, with you playing a male or female partner. (Or if you think you’d make a better Bloodrayne, go for it.) Curious to try BDSM and-or non-con elements. Rayne could be either the dom or the sub. (Probably dom if the other char is female, sub if male.)

A plot motive for the activity, like interrogation, punishment, or training, would be nice. I am open to specific ideas. Perhaps Rayne is training a would-be discipline and subjecting her to stuff to see if she has what it takes. Perhaps Rayne has been captured by a bad guy. Perhaps one is seducing the other to get information.

Rayne is a few centuries old so there is some choice as to place and time, it could be in the Victorian Era, Nazi Germany, or modern day, or any time/place in between. 

It's fine if you're not familiar with Bloodrayne: basically, she's a dhampir (a half-vampire who can handle sunlight) who makes a career as a vigilante hunting vampires, Nazis, etc.
