I do not own Naruto or any of its characters. That lucky bastard is Masashi Kishimoto.
Kakashi had returned from a mission just a few days before, having awoken that morning. Unfortunately, his house had been somewhat destroyed by a handful of rouge ninja, so he was staying with Iruka. His clothes were stained with blood; his face and hands were filthy. Naturally, he thought it would be wise to take a shower. He got a towel and walked down the hall to the tidy bathroom. He began to undress and eyed the clock. '3:00…' he thought. 'Iruka should be on his way home about now.' he washed the filth out of his matted hair. As the water massaged his pale skin his mind began to wander. Thoughts crowded his head. Thoughts of the man he secretly loved. Thoughts of Iruka. After a moment, his thoughts began to go somewhere he hoped they wouldn't. He tried to stop them. Too late. He felt himself grow harder and harder, the organ just below his abdomen crying out for attention. He was tired of being pleasured by his own cold, unloving hand. He reached for his member as though he were a robot programmed to do so. He began to slowly stroke it, picturing the sweet smiling face of Iruka. Iruka had just returned from another day of teaching. The sound of running water startled him a bit. When he had left, Kakashi was unconscious. He walked up the stairs and down the hall, stopping at the bathroom door. He pictured the silver-haired man's wet, naked- he snapped back into reality when he heard a moan. Was Kakashi okay? Did he fall and hurt himself? No. He's far too smart to do that… then again. He rushed into the room to see Kakashi with his hand wrapped around his member, calling Iruka's name, as if he were completely unaware of the fact that the man was standing right in front of him. With one final jerk, he came, once again moaning his obsession's name "Mmmmmm, Iruka."The tan man couldn't stand it anymore. He turned off the water, wrapped a towel around the startled jonin and carried him back to his room. "I-Iruka!"
"Shhhh…" Iruka cooed. "Kakashi, I think I know what you feel for me, and I want to say that I feel the exact same way. I have for a long time and it was torture having you here. But now, I can finally say this. I love you."
"I love you too, Iruka." He said, capturing the younger nin in a loving kiss.
