Book of One-Sh!ts

[Kaeya x Albedo] Heavenly Visitor

The pure white wings flapped as his feet gracefully touched the ground of the fallen city that had many moons ago descended into what was known as Hell. Kaeya didn't move from his spot on the warm lava rock. He shifted slightly only to allow himself a better look. 

"What's an angel like you doing in a place like this?" he chuckled. 

"I require that you provide assistance for my research." 

"Me?" Kaeya pointed to himself. Perhaps this was a situation that required his full attention. He sat up and crossed his legs. The dark demon wings contrasted greatly to this angel's feathery ones. He found the need to make them less noticeable by bringing them closer to his back rather than outstretching them. 

"I believe that it would be quickest to ask a succubus such as yourself the reason why humans are obsessed with intercourse outside of reproductive means." 

"You want to know why humans have sex?" 

"That is what I said." 

"And you want to ask me about it?" Kaeya pointed to himself. 

"Must I repeat it?" the angel didn't frown but his wing twitched in annoyance. 

"Aren't you worried I might seduce you? Cause you to fall from grace? Turn those wings to ashy shards of what they were?" 

"It isn't seduction if I'm the one asking you," the angel gestured to the demon. "Please provide me with a physical demonstration if at all possible." 

"Are you asking me to have sex with you now?" Kaeya raised an eyebrow. 

The angel brought his hand to his chin. "I had assumed that would be the easiest method to provide an explanation. Was I incorrect?" 

"I haven't even agreed to be a helpful participant in your research," Kaeya shook his head. "Aren't you getting a bit ahead of yourself?" 

"Ah, should I look elsewhere?" 

The succubus felt guilty imagining what would happen should another demon take over this poor angel's questioning. There would be no limit to seductions or temptations. He would surely lose the purity in his wings. Feeling responsible for him now, Kaeya reluctantly shook his head. 

"No need, I'll assist," he sighed. 

"Wonderful, we shall start right away," the angel glided forward and sat on Kaeya's lap. "Begin your explanation," his eyes glimmered with curiosity. 

"There are many reasons why humans pursue sex," Kaeya began but didn't place a hand on the angel. "Some do it for pleasure, some do it as a display of pure intimacy, others do it to create families..." 

"I don't understand what's so exciting about the sweaty exercise." 

"I'm afraid there is not much I can do for you," Kaeya admitted. "If you're not attracted to me or at least a little bit perverted my succubus powers have no effect." 

"Humans have no such powers." 

"Ah, right," Kaeya chuckled awkwardly. "You're sure you won't fall from grace by doing something like this with me?" 

"I don't see why it's any concern of a demon if I fall or not." 

Kaeya couldn't answer that. 

"This is research. You're answering my questions unless you're refusing," the angel grabbed Kaeya's hand and placed it on his chest before climbing into his lap. His skin was smoother than he expected. Kaeya's hand slid under his white robes. No reaction. This wasn't going to be easy. Kaeya was starting to feel very inept in his succubus experience.
