“No! Don't kiss me like that!” Iruka's voice was tight with anger, with fear. He shook Kakashi, hands clutching his vest, “You're coming back,” then again, “You’re coming back.”
Kakashi's fingers trembled where they rested against Iruka's neck. He kissed Iruka again, and it still felt like ‘goodbye,’ and Iruka broke away with a choked gasp.
“I can't do this, I can't-” His eyes were burning, and his chest felt tight. Iruka pressed a hand against his sternum, willing the overbearing pressure to stop, but it wouldn't abate.
Kakashi's cold fingers brushed over his cheek, and his next kiss tasted like tears, and Iruka thought, ‘I'm going to die, I'm having a heart attack. I can't breathe. I need to go to the hospital.’ But his next breath came with a keening sob and Kakashi was whispering “Shh, it's okay, it's okay,” pressing kisses to his unfeeling lips.
“Please don't-” ‘Please don’t go,’ the words hovered in his mind, screaming, twisting in his gut. He couldn't say them. If he did there was a chance Kakashi would listen, and then they would both be traitors. Iruka's vision was blurry, and blinking wasn't helping. Kakashi kissed him again, and their lips dragged apart, and Iruka whispered, “Please don't kiss me like that.”
