Hunger Pains
When he was hungry he could hardly concentrate. When he was famished he could barely breathe. Every time the ninja passed him he couldn't meet his eyes for fear of losing control and taking to much. It was like a great and terrible thirst which was ironically never quenched. He could never drink enough to satisfy because to drink enough would surly bring death to upon his unwanted saviour. Not only that but he hated the intimacy of the act. He hated feeling Kurogane's heart beat drum in his ears as it reminded him of happier times when a hearts pace was quickened by a playful joke and laugh between friends.
