Naruto clings so desperately to him when their lips meet for the first time. He wholly mauls Kakashi, teeth bared and small gentle tears trickling from his eyes. Naruto is all light and carries his burden of shadows, darkness, pain fully and with no regret. To be honest he thinks Naruto needs it, feeds and thrives on it makes his life bearable, meaningful.
He can feel Naruto's hardness digging into his thigh and its so real, but at that same time Naruto's tears hit Kakashi's cheeks breaking what ever genjutsu that was making him think this was even a little okay. Kakashi knows that all the hurt, guilt and untamed demons the rest on his shoulders will do nothing to sate Naruto. Now Kakashi wants to cry out and curse himself for being selfish in thinking this light that is Naruto can be harnessed by him.
"Naruto." Kakashi works his lips away from the greedy captor.
"More!" Naruto pleads, forcing himself closer and his hands bury themselves tightly in Kakashi's hair.
"Will I be enough?" Kakashi asks, hoping. Naruto pulls away. For a brief second he meets Naruto's eyes and sees his answer. Kakashi silently curses Sasuke.
