Our Little Secret

I have a best friend that I hang out with more than 10 years. We are together from college. We past a lot of crazy, happy and sad moments together and we really love each other. I have an admiration to my best friend because she is always so supportive to me and she respects any decision that I will make.
However, I must admit that she has a gorgeous brother. He is 2 years older than me. He is blonde, tall with big green eyes. His smile is adorable and the way he speak, it’s make me to feel that I’m in heaven. Fortunately, he doesn’t have a girlfriend, but unfortunately I have a boyfriend like 6 months ago.
Whenever I’m going in my best friend house and her brother is there, I can see the way he is look at me. I can feel the chemistry between us, but I never told that to my best friend.
