The Room Upstairs

We were never supposed to touch. Raised under the same roof, we were brother and sister in all but blood. Our bickering was a constant storm, a flimsy shield against the lightning that arced between us. But one night, I stumbled upon her most private moment, and the storm broke. The lines we never meant to cross were washed away in a flood of sweat and sin. Now, every hallway is a temptation, every closed door a challenge. She wants to repeat our mistake. And God help me, I'm afraid I want it too.
