Don't be ashamed of your feelings. You may not know it but she is probably hot for you too is why she loves to show off to you. This may sound bizarre but I was born and raised in the south. I was never raised to be racial, some of my best playmates were black. Even today I detest hearing people refer to them as n****rs and such. Now, I am in the military and lots of black girls work in the Base Exchange. (Oh no, I just gave myself away. Yeah, I'm in the Air Force. The army refers to it as the PX, Post Exchange.) So, I have made friends with several of the blacks, who are still single. I refuse to flirt with the married ones. Anyways, I have paid many times for their lunch and while eating we can't keep our hands off each other, under the table. Two of them I have fucked many times without the other knowing. Cheating? Maybe but it's wonderful. At least, in my position in the AF I have my choice almost all the time. I am never hurting. So, make a pass at her, 5 will get you 10 that she will accept.
