She knew well what she was provoking in him, but he had controlled himself as much as he could, he was determined not to let himself be carried away by her dark desires, she was his family, maybe not by blood but he had grown up with her and although their relationship as step-siblings had never been perfect knowing that she had this desire for him could upset him.
