You know it: I own nothing. I didn't write it with twincest in mind but you can see it that way if you wish.
The man sat up awake a scream dying on his lips. It took him a moment to calm his erratic breathing then he put his hands to his forehead while closing his eyes. What a nightmare. He was there, hands red from all the blood. And in the middle of all of this was the Goddess. He was the one who killed her. Again. But then her body had changed and it wasn't her anymore lying in a pool of blood. It was his brother. Kanon. That's only at that moment that he had woken up. When he realized he had killed his twin.
He couldn't go back to sleep. Not after that. He was feeling bad. He hadn't woken when he had killed Athena in his dream, but only when he saw Kanon's dead body. He had placed his brother above Athena. Above his Goddess. What kind of a Saint was he? A bitter smirk found his way to his lips at that thought. He was the worst kind of Saint. He knew he would always put Kanon above her. He had finally admitted that much. He chuckled. Took him long enough.
"Screaming like a banshee one instant and chuckling the next… If I didn't know it was already the case, I would say you've become a complete nutcase." That mocking tone could only belong to one man. And true enough Kanon was there leaning against the doorframe, wicked smirk in place. "So what's the matter dear brother?" When he got no response worry slowly appeared in his eyes. "Another nightmare?" But he needed no response. He already knew. He always knows.
Kanon approached his brother to sit on the bed with him. He studied the older twin a little before placing a gentle kiss on his lips. The rest was sweet whispers. "Don't worry. They're only bad dreams. They can't hurt you. They can't hurt us. Calm down." He kissed him again on the lips before slowly lying Saga on his back. Kanon then curled himself against his brother's side. "Don't worry. I'm here for you. I'll always be there for you. Now sleep. There is nothing to fear." He let his hand wander on Saga's side before settling it over his twin's heart. And that's how Hypnos took the twins in his embrace.
