Hashirama Senju noticed Madara Uchiha glowed when he was kissed.

Madara always seemed to be surrounded by a pearly sheen, but now, with the kiss, he truly glowed, so much so that Hashirama didn't believe his own ability to enlighten the world was needed.

The kiss tasted of light, of soot, of burning gasses and of love. All that love. Hashirama didn't feel the relief he thought he would feel when they kissed, though, of a missing piece in him being fulfilled. Instead, he felt a deep satisfaction outside of himself.

Neither of them felt cold in bare landscape; their sensations were tuned into one another only as they lay down on the ground. Hashirama placed kisses down Madara's neck, and Madara sighed happily, smiling at the warm touch of Hashirama's lips on his skin. Endlessly carefully, the sun stretched his love.

"It burns", the moon whispered.

"Do you need me to stop?" the sun asked, afraid of hurting the moon. 

"No", the moon said, grabbing the sun's arm. "No, it feels right."

The moon lay naked before the sun then, the sun with his robe open as the moon guided him into him. The moon had his legs around the sun's waist, and the sun wouldn't let go of the moon's eyes, even if the moon tried, several times, blushing.

"No", the sun said, grabbing the moon's face, turning it towards him. "No, look at me."

The moon did, knowing he would do anything for the sun, just as the sun would do anything for him. 

The moon sighed the sun's name as he came for him, making the sun smirk; he was so pleased. He grabbed the moon's hand and kissed it over and over, in awe that he could give someone like him so much pressure.

But the moon put his lips to the sun's ear.

"Lay down", he whispered.

"Why?" the sun asked, believing they were done.

The moon smiled his precious smile, a smile that would hold humanity in awe for hundreds of thousands of years.

"Don't you trust me?"

So the sun lay down because of course he trusted his moon, and the moon went down and placed his lips to the sun, still erect, still searching, still yearning.

"Madara, what..."

Then, he couldn't speak as the moon took care of him with his mouth, could only lean his head back and sigh. The moon was a gentle man, being careful not to use his teeth on accident, and the sun put his hand in his hair and pulled a little, letting the moon know he was grateful.

"You're so good", he purred. "So good to me."

The moon looked up and smiled, and then, he changed completely. Sucked like a madman, gagged himself, spit on him to masturbate him. The sun screamed in pleasure, and it took only seconds for him to come.

The moon curled up into the sun's embrace, and the sun held him, both panting, looking up at the starless sky.

"This moment is almost perfect", the sun said.

"Why almost?" the moon asked.

"It would have been better with stars. It saddens me that I will never be able to see them."

The moon took the sun's hand.

"I feel the same", he said. "About my little brother. I want to find him again."

And just like that, ice cold dread grabbed at the sun's heart. Hadn't he had the moon entirely? Hadn't he belonged to him, Hashirama, alone? For the first time, he felt angry with the moon. Was this the thanks he got for having taken care of him for so long?

But where were this thoughts coming from? These weren't thoughts made by his true self. These were thoughts of his obsessive self, the Hashirama that was trapped beneath the surface. 

Still, he panicked as he imagined his life as it was but without the moon by his side. How could the world keep spinning if they were apart? 

The moon fell asleep next to him, but the sun could not sleep. Instead, he wandered the earth alone until he found Tobirama. Izuna was nowhere to be seen. 

He fell down on his knees in front of Tobirama. 

"Brother, what is the meaning of this?" Tobirama asked, looking aghast.

Hashirama took both of Tobirama's hands in his. 

"Please..." he said, his voice breaking. "Please. Izuna... You have to. You have to do what you promised me."

"But I thought you and Madara were already close!"

"He can't stop thinking about Izuna... Please..."

"But I love Izuna!" Tobirama screamed and ears were streaming down his face. Hashirama had never seen his brother cry before. "Please, don't make me choose."

So that was it. Tobirama knew where Izuna was, but wouldn't kill him. Hashirama had started to suspect it, and found he wasn't angry.

Hashirama leaned his forehead against Tobirama's hands, one part of him ashamed of what he was about to ask, that part that was aware of what he was truly asking.

"Please... Please, if you ever loved me... If you still hold the smallest piece of love for me... Please, kill Izuna."

Tobirama just stared, crying.
