I am the Demon King, but it’s my first time being imprisoned

by Lilium — I was reincarnated as a Demon King fated to kidnap, imprison, humiliate the hero, and then be torn apart to death. At this rate, I would go down in Demon King history as the one with the shortest lifespan. I decided to change my fate. I handed the hero treasure and even left the main gate open. But… * The hero stood with a…

by Lilium — *** ‘It’s cold.’ Upon arriving in Genzar, Sibel realized Leviathan’s words were not empty talk. He directly experienced the biting cold. Genzar was far harsher than what Leviathan had said. Not only the cold, but all road leading to it were barren. He almost suspected that the flower photos sent earlier had been fabricated. But one thing he liked about this place was the scenery. The blue sky, the white ice, the frozen surface of the blue lake. Everything in sight was dyed in blue, and…

by Lilium — The creature, trembling and glancing around nervously at his question, looked human no matter how he saw it. “Were you captured too?” This silly-looking human trembling like this could only mean, in his conclusion, that he too was a hostage captured by the perverted Demon King. “Y-Yes?” Every time he spoke, he flinched as if startled, not seeming the type suited for playing at being a hero. His face was male, but with slender lines, a fragile, pure atmosphere. It seemed clear he was…

by Lilium — “I understand. You’ll be honest with your emotions for a while and find it hard to restrain impulses.” Leviathan soothed him calmly. He even handed Sibel a handkerchief from who knows where, for his sniffling nose. After watching Sibel wipe his tears for a while, Leviathan smiled lightly and offered him a cookie from the table. In the center of the round cookie was sweet strawberry jam. Sibel accepted it without thinking and put it in his mouth. As the sweetness filled him, peace settled…

by Lilium — Ramiel calmly drank from the cup in his hand as he replied. “It would be a shame to miss such a good spectacle.” “Is that act of kindness reserved for the Demon King only? To me, you show your dog-like self without filter. For a human, you’ve no fear.” At Aizen’s words, Ramiel let out a small laugh. “Isn’t it the opposite? If I’m human, then I shouldn’t have to fear you.” “What?” “Isn’t that right, Apostle?” Aizen felt the sting in his words. “What…

by Lilium — Sibel panicked and tried to push Aizen's shoulder away. But Aizen remained as unmoving as a rooted boulder. "You seduced me first." "When did I!? I just felt ticklish… Ugh!" Aizen thrust his hips up without warning. "Hah!" Sibel's head fell back. The hard glans rubbed mercilessly against his already hypersensitive inner walls. He'd just ejaculated, so he'd thought his senses had gone numb, but instead, the pleasure was even stronger. "Ah, ah! Aizen, wait, hhhhh…!" "500 years,…

by Lilium — “Why are you not on their side?” Did he think that since they had summoned him, he had to be on their side? “They didn’t summon me. They summoned a Demon God.” The heretics weren’t worshipping him anyway. What a ridiculous question. If anything, the situation was dangerous because once they discovered who he really was, they might turn on him and try to kill him. “What do you want from me?” “First, we deal with the palace, then I go home, and you drive out the…

by Lilium — Aizen and Shanti, who had come after hearing rumors from somewhere, froze when they saw the half-naked muscular human. Their gazes passed over the human and landed on Sibel, who was standing in front of the chair. “……” Familiar. A look of contempt and disgust, as if seeing a pervert. This is really unfair, but he can’t argue back. “It’s a misunderstanding.” “…You still haven’t fixed that habit.” Aizen recalled the first time he had come here. “It’s not a…

by Lilium — As his grip tightened, Sibel’s mouth opened naturally. “Ah…” The instant his lips parted, the tongue that had been sweeping his teeth slipped inside as it had been waiting. The tongue, as unruly as his temper, licked the roof of his mouth and wound itself around Sibel’s tongue. Their tongues mingled together, sending a tingling shiver down his spine. The sticky sound of their tongues rubbing against each other, their saliva mixing, blended with sound of the rain. Aizen swallowed…

by Lilium — “Since it was resolved well, that is enough. As for the damage, just a little… hm, a little more than a little of the building was destroyed and, well, the garden… reduced to ashes. That is the only loss.” Sibel spoke while looking out at the garden, which had turned into a mess. “As a compensation, though it may seem small, I will give you this.” Cloton’s hand moved. A large sack dropped with a clatter beside him. The sound of metal clashing came from inside the…
