From Different Worlds

I have a friend. He is about six feet tall, handsome, incredibly hot. Not only that, he also has the purest soul.
Long before we became friends I had developed an enormous crush on him. We slowly became closer and closer, spending nights full of talking, sharing thoughts and laughs.
While he saw me as a good friend, I was in love, falling deeper and deeper.
In my mind I picture us in various scenarios making love to each other. Whenever I see a couple I can't resist thinking of him, wishing to turn all that energy that has built up inside of me into a night full of pleasure with him.
These huge feelings of love are making me insane and I can't think of anything else.
The heart-wrenching thing is that it is never going to happen since we are of two different castes. I don't know what to do. My body and mind are craving for him and it is just a matter of time until I am no longer able to control myself.
