"Remind me," Aomine said, leaning on the tree branch nonchalantly "what exactly are you doing here?" His deep blue eyes watched how the wings on the angel's back slightly moved and he wondered if they were really as fluffy as they seemed to be. When the angel just raised a brow at his question, he groaned "I mean, what your sacred ass is doing here, Kagami?"
Kagami smiled at him "You know, I just have to watch over your ass. That's my duty."
No, this wasn't going anywhere, really. Aomine is a demon for fuck's sake. How he's supposed to do something evil if there's this cute angel who just won't leave him alone? Seriously, Aomine wanted nothing but to do his job, goddammit, and go back to hell, where his place literally is. Was it that hard to leave him alone for a moment?
Aomine rolled his eyes and outstretched one hand, his body still leaning on the branch. Kagami was sitting under the tree and was reading something, his wings big on his back. Aomine reached and brushed his fingers against the white feathers and felt Kagami shiver, before the angel jumped on his feet, his face flushed.
"Oh." Aomine said, and then his surprised expression turned into a smug one "Oh." He repeated as a smirk plastered on his lips. He jumped from the tree and tried to approach Kagami. But Kagami wasn't staying still as well. With each step Aomine made forward, Kagami made one backward.
This small chasing act ended when Kagami's back hit a wall and now, the angel was trapped between a wall and a demon, who was deviously smiling and licking at his lips.
When Aomine was just a breath away from Kagami, he asked in a whispering tone "Are your wings that sensitive?" One hand was trapping Kagami, so he won't be able to run away, and the other one went to brush the soft feathers. He felt Kagami suck a sharp breath in, his cheeks turning bright red just as his hair.
"Stop it, Ahomine." Kagami panted. Even the tips of his ears were red. Aomine grinned triumphantly.
"Or what?" the demon purred into his ear, sin practically dripping from that voice.
"You… better… don't know that." Kagami said and tried to push at Aomine's chest, which was positively naked. Fuck. Probably demons had no shame to walk around like that.
Aomine hummed appreciatively at the skin-to-skin contact, and it felt like where Kagami touched him burned.
Literally burned. What the hell.
Aomine jumped away and started rubbing at his abused skin. Kagami looked horrified at him.
"Sorry, Aomine, I didn't mean to –" Kagami started rambling incoherently while his eyes avoided Aomine's. The demon sighed and approached him again, cupping his face and making Kagami look at him again. There were tears in those ruby eyes.
"Shhh." Aomine shushed him, wiping at his eyes. "I know."
"But how –" Kagami gaped at him.
"Because your heart is too pure." Aomine smirked and leaned, barely brushing his lips against Kagami's cheek "Even when it comes to evil, you're too pure to harm it. Your powers do it for you, though."
"But why –"
"Because I want it, Kagami. I want to touch you. And I'm doing what I want to do."
At that Kagami blushed, trying to pry off Aomine's hands and that got burned over and over with every touch of Kagami's fingers on his skin.
"Let me go, you idiot!" Kagami yelled at him, tears running down his cheeks as he saw the damage on demon's skin.
"No, I won't!" Aomine yelled back, still holding onto Kagami's face. He winced at the pain "Stop squirming and let me kiss you already!"
Kagami's eyes went wide and he stopped moving. Aomine panted, his forehead was sweaty and his burned skin was already healing, but Kagami was sure it hurt a lot.
Then Aomine smiled. "That's better." He whispered and leaned to steal a kiss from this pure creature, whom he died to touch from the very moment he saw a glimpse of that crimson hair and eyes, which shone brighter than sun itself, from the very moment he saw that smile, soft and sincere, and more importantly, directed at him, a demon, someone he should hate.
Aomine wanted to stain him – it was his nature after all. But even after they parted, even with his lips swollen and cheeks red, Kagami was smiling at him. Kagami whispered his name. Kagami leaned to kiss him back.
