Kabuto was your superior,you both worked under orochimaru, he loved to tease you, see how far he could go with you, send you over the edge with fear and excitement. he had you bent over his table and he was behind you with his scalpel on your stomach "You know I have a very steady hand, but that won't matter much if you buck into the knife” Kabuto cooed softly in your ear he was a very capricious person, he was balancing you at the edge now and he was very good at it
