An seduction idea for her 1st BBC

I would like to introduce a dominant black man to my gf as someone I served with in the military. Someone who outranked me so that we could establish them in a clearly superior role and also to validate what will be a lack of familiarity between us. My gf loves military men and would respect and admire them immediately. This way suddenly having a black man around for takes & a movie wouldn't seem strange.

Being submissive by nature, she has a "go with the crowd" attitude so, if the bull were to come onto the scene and I gradually adopted the role of a servant then, she would probably adapt to that pretty quickly and hopefully begin to concentrate on his presence in the room.

The idea is to slowly introduce a dominant figure into the relationship and create a pattern of my being treated more and more as less-than and her as the focal point and object of desire. My role will have been established early, leaving the bull time to work on seducing her.

Does this seem like a reamisterable plan?
