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 — Aizen, who had ejaculated profusely between Sibel's legs, kissed him again. As he gasped and returned the kiss, Aizen's hand brushed against his cock between Sibel's thighs and moved down. The hand that had stolen his own spilled semen gradually slid lower. His hand pressed against the tightly clenched entrance of his anus. Sibel's startled body flinched, and Aizen's tongue slowly withdrew from his mouth. A finger forced its way into the narrow slit of the hole. “Huh, s-stop,…

by Lilium — *** “…bel, Sibel!” Someone’s desperate voice called out. Sibel’s eyes opened. A foreign sensation pricked his wrist. His body felt damp, perhaps from sweat, and his fingertips tingled. ‘What is this?’ And before his eyes… “What... are you doing?” A cracked voice escaped his lips. Aizen was perched on his stomach, pressing down on his body. This bastard... while I was sleeping peacefully... “An assassination attempt?” At Sibel's words, Aizen's already twisted…

by Lilium — “I really don’t feel like answering nicely.” “Your personality really is twisted…” “If I dump you like this on the marble, will your tailbone shatter?” Sibel shut his mouth. This position was definitely disadvantageous for him. “So, what kind of dream did you have?” “Well... just some nonsense. Put me down.” “We're here.” Sibel asked to be put down, but Aizen had already arrived at the door while still holding him. He used some kind of technique, he didn’t…

by Lilium — Slightly squinted eyes, a piercing gaze, a deliberately crafted gentle expression, a low voice. A danger siren blared in his head, warning that a wrong answer would bring great trouble. “No, it's just that you're so exceptionally charismatic and popular... I couldn't believe you'd never done something like that before.” Even at Sibel's awkward excuse, Aizen's gaze didn't soften. “You seem to be avoiding the question.” “Ah, no! Who's crazy enough to rub their dick against a…

by Lilium — In the end, Sibel fell asleep leaving his messed-up genitals untouched. Aizen found the sight of Sibel sleeping with such a refreshed face ridiculous, but he dutifully cleaned up after him with a damp towel. He properly positioned Sibel's body, which had sprawled across the bed, aligning him with the pillows. He assumed the two pillows were naturally meant for him and claimed the remaining spot. He believed he had earned this right by sacrificing himself to serve Sibel. And what could he do about it…

by Lilium — “No! Why are you just flopping that monstrous thing out like that?” “Monstrous? Flopping?” Aizen's brow furrowed. It was an unapologetically rude remark to make to someone who had just served him with their hands. But from Sibel's perspective, Aizen's thing couldn't help but look monstrous. It was unclear how long it had been erect, but its size alone – as thick as a child's forearm— was overwhelming. Dark and rigid, it resembled a weapon. A viscous liquid glistened at its tip. Staring…

by Lilium — “Gently stroke the shaft, grip it just right. Then down, up, like this...” Aizen taught Sibel how to grip his cock as if giving him a lesson. Each time his hand moved up and down, Sibel closed his eyes and then opened them. He felt heat pooling around his eyes. “Haah...” “Scratch the spot protruding just below the glans too.” Aizen's fingertips scratched beneath the cute, pink glans, crowned like a cap. At that moment, fluid pooled in Sibel's genitals. The finger that had teased…

by Lilium — ‘You think I would…?’ Who would he show such a shameful sight to? Sibel quickly crossed his legs. But to block his movement, Aizen’s leg caught hold of his shifting limb. “…….” Even as he strained every muscle to pull his leg back, Aizen didn’t budge an inch. Have you spent the last three years only working out your lower body? You're putting me in a really awkward spot. Sibel glared at Aizen. His body leaned forward as he looked down at him, his hair spilling over his…

by Lilium — Light pours down from the sky. On the ground, lava boils and metal shards fly through the air. All around, people are dying. Over and over, again and again… "Ah!" Sibel jolted awake, startled. It had been a terrifying dream. Lately, he'd been plagued by these strange dreams every time he fell asleep. The moment he awoke, he felt warmth on his forehead and the tips of his ears. It seemed every vulnerable spot on his body had grown hot. Was his body weakening? Maybe he should try samgyetang…
