  Summary

  "Iruma hadn’t been one starved for validation, at least not in a long time. He went from getting zero affection at all (except for maybe a light pat on the head after he did an extra good job) to being absolutely bombarded with it on all sides, from his grandfather and friends alike. There were often times when he still felt starved of it, though, perhaps because his body was so deprived of it. And he felt sort of guilty about that, because he should be getting enough attention. He is. So why did he still feel like every touch or compliment wasn’t enough?

  This, though. Maybe this was the place to get that extra attention that he wanted. Already, just that little bit he got felt like flying. It was like a drug- well, at least what he imagined drugs would be like. He felt his heart beating hard in his chest, skipping and thumping like a drum."

  Or, after some convincing from Lied, Iruma decides to dip his toes into the realm of Internet homemade pornography.

  Summary

  “You’re so pretty, Kirio-senpai.” The words come tumbling out of his mouth without him really thinking about it.

  “I’d look even prettier covered in blood, wouldn’t I?” Kirio taunts.

  Yes, he absolutely would. Iruma nods and grits his teeth.

   

  Or, Iruma doesn't have sharp claws or teeth like a demon would, so in order to satisfy Kirio's urges, he has to get a little creative.

  Summary

  “Iruma.”

  “Yes, sensei?”

  “You’ve clearly had sex before,” he says. “With whom?”

  Iruma giggles. “Why is my sex life your business?”

  “You’re fourteen years old. You shouldn’t have a sex life.”

  “That’s funny, coming from the man who has me impaled on his cock.”

   

  Or, in order to get his grades up, Iruma decides to show Kalego a good time for the first time in his life.

  Summary

  Being a member of the Demon World Reformation can be pretty tiring. Luckily, there's a couple ways that one can blow off steam.

  Summary

  "Nothing could break Kalego. At least, that’s what he’d insisted had been the truth for years. He was raised by a mother and father that carried business and outward appearance more important than anything else. His older brother, whom of which he simultaneously has not seen in years and knows is one of the richest men in the country, was a stunning for example for Kalego growing up. He’d worked hard for the thirty-eight years of his life he’s been alive. He’d fought tooth and nail to get to where he is today.

  Yes, of course, Kalego was a strong man whose composure and morals could not be broken.

  And then along came Opera."

   

  Or, Kalego and Opera let go of their inhibitions.
