"Why have you painted your wings pink and covered them in glitter?" Castiel asked with the most sincere confusion.
Lucifer stared at him; a look of boredom. "Because I don't give a fuck."
Castiel was not satisfied. "That doesn't justify—"
"Look, the cherubs like it. That's more amusing than your reaction, brother. I was expecting amusement, since Sammy won't pay attention to me."
Castiel narrowed his eyes, clearly offended by the answer. The cherubs gathered behind him, though, squealed in delight, giggling and gossiping among themselves. One in particular—Cupid—could be heard saying, "Oh, they're like the color that symbolizes tenderness and romantic affection on earth! Eee!" Castiel rolled his eyes and groaned, disapproving of the behavior.
Lucifer crossed his arms and smirked at the angel, his eyes still hooded with the appearance of exhaustion. Then, he raised his brows, realizing how fun it would be to act out his sudden idea.
As the nerd-angel argued with the cherubs that such a blasphemy to sacred limbs wasn't to be tolerated—or for that matter admired—Lucifer slowly stalked towards him.
When Castiel saw that the group of cherubs huddled closer together, he grew silent and glanced over his shoulder. He was greeted by the huge grin on Lucifer's face. A face far, too close for comfort.
"Little brother, I'm going to paint your wings."
Castiel was horrified at the thought. "NO."
"It's not like I'm asking your permission," Lucifer chuckled and aggressively took Castiel by the shoulders. "Be good, or I'll rip them out."
Castiel froze in his grip, eyes wide from shock. The cherubs were gawking at the two and commenced their whispering.
Suddenly, Lucifer forced Castiel to turn around. Now facing the cherubs, he pushed him to the floor on his knees. He slowly moved to his ear and softly sang "I'm a killer, cold and wrathful. Silent sleeper, I've been inside your bedroom. I've murdered half the town…left you love notes on their headstones. I'll fill the graveyard, until I have you."Castiel shuddered as Lucifer's mouth moved on the skin of his ear."Moonlight walking, I smell your softness, carnivorous and lusting, to track you down among the pines. I want you stuffed into my mouth." He strengthened his grip on the young angel's shoulders. "Hold you down and tear you open, live inside you." He laughed softly, "Love, I'd never hurt you." He took Castiel by the neck and shoved his face into the floor. Castiel whimpered, knowing that Lucifer had complete control, being so powerful and he a mere grain of that intensity. Then, he felt warmth as Lucifer breathed onto his neck, "but I'll grind against your bones until our marrows mix," and grazed his teeth over the skin, "I will eat you slowly."
