The night was wrapped in silence. Outside, crickets sang, and the wind rustled the branches of the forest. Inside, the only sound was Muichiro's calm breathing, sunk in deep sleep. His head rested on Kokushibo's lap, his dark, silky hair spread across the demon's thighs.
Kokushibo stared at him intently, his six eyes fixed on every detail: the long eyelashes, the slightly parted lips, the chest rising and falling peacefully. There was something about that innocence that completely disarmed him, a stark contrast to the sinful desire burning within him.
He reached out and brushed the boy's soft cheek, trailing down to his neck and then to his chest. The yukata fabric barely covered the slender body, and Kokushibo slowly parted it. His thumb caressed a nipple, and Muichiro sighed in his sleep, his small body arching.
"Beautiful... even asleep, you respond to me" Kokushibo whispered, leaning down to cover the boy's chest with wet kisses.
His lips traveled over the chest, the flat stomach, every tiny curve. Every unconscious moan that escaped Muichiro etched itself into his mind.
"Even asleep, you belong to me."
He untied the yukata's sash and opened it fully. The naked skin glowed under the moonlight, perfect and vulnerable. Kokushibo leaned between his thighs, parting them with insulting ease due to the size difference.
His tongue found his intimacy immediately, licking with obsessive devotion. He buried his face in the wet softness, exploring every fold with a desire bordering on worship. The taste intoxicated him.
Muichiro whimpered softly, his hips trembling while still asleep, his little body seeking more without knowing it.
"That's it, little one... even in your dreams, you let me in" he murmured against his intimacy before plunging his tongue deeper.
The boy pressed against him, his small hands clenching into fists on the demon's kimono, without opening his eyes. He was panting, his parted lips letting out moans.
Kokushibo shuddered with every reaction. He inserted one finger, then two, preparing him patiently while continuing to taste him. The warm interior gripped him tightly, so narrow it nearly drove him mad.
When he had him ready, he easily lifted him into his arms. Muichiro was so light he felt like a doll in his hands. He positioned him better on his lap, holding him with one strong arm around the waist.
With the other hand, he freed his thick member and guided it slowly to the narrow entrance, pushing with gentle pressure.
Muichiro's body trembled, a whimper escaping his lips. His eyelashes fluttered, but he didn't wake. He weakly clung to the demon's chest, as if seeking safety.
Kokushibo held him close.
"Shhh... relax, little one. Just let me fill you... you're perfect like this" he whispered, his voice husky with possessive tenderness.
He sank into him little by little, feeling how the small body received him with difficulty. The throbbing interior gripped him hard, and Kokushibo held back a groan. So tight...
When he was fully buried, he didn't move right away. He simply held him, stroking his back and kissing his forehead, letting him adjust in his sleep to the deep invasion. Muichiro writhed gently, letting out a sleepy moan that made him shudder even more.
Kokushibo began to move slowly, with long, deep thrusts that filled him completely. Muichiro's body reacted, clenching tightly, trembling with each push. Though still asleep, his lips murmured incoherent words, as if he knew exactly what was happening.
"Yes... that's it, clench me like that" Kokushibo gasped against his ear. "You don't need to wake up, little one. Your body already recognizes me."
With each movement, the boy clung to him more. His sleepy expression was full of pleasure, cheeks flushed, mouth parted. Kokushibo kissed his lips softly.
"So beautiful... Muichiro..." he whispered between gasps, quickening the pace.
He held him with both hands, lifting and lowering him slowly, making him ride his thick member. Muichiro whimpered softly, his trembling legs spreading wider, giving him full access.
The demon no longer held back. His thrusts grew firmer, more possessive. He filled him again and again, feeling the narrow interior clench relentlessly. Each time he pushed deeper, a delicious whimper escaped the boy's lips.
Muichiro shuddered, reaching a trembling orgasm in his sleep, his stomach stained with his own release as he sobbed softly. Kokushibo held him, murmuring praise.
"So sensitive... so good for me..." he said in a husky voice, without stopping.
He continued thrusting, ignoring the small body's sensitivity. Every time Muichiro trembled or cried softly, Kokushibo soothed him with kisses and caresses while driving him to another orgasm. Once, twice, three more times, until the boy trembled weakly in his arms, tears of overstimulation running down his cheeks.
Finally, when he could no longer hold back, Kokushibo hugged him tightly and filled him to the hilt with a deep groan. He kept Muichiro on his member, pressing him close so nothing escaped.
He stayed like that, holding him, as the boy sighed weakly in his sleep, resting with his face buried in his chest.
The silence enveloped them again. Muichiro remained asleep, exhausted, face buried in Kokushibo's chest, his breathing still shaky from having come multiple times in his dreams.
The demon held him against himself, still buried inside, keeping him full.
He watched him a moment longer, caressing his cheeks wet with tears of pleasure, and a smile curved his lips.
"There's still more of you I need, Muichiro" he whispered deeply into his ear. "Not just here... I want to possess you completely."
With a slow movement, he withdrew his member from the soaked intimacy and laid him face down, supporting him.
The white, fragile back arched gently, exposed and vulnerable.
Kokushibo kissed his nape, trailing his lips down the spine until reaching his buttocks.
He parted the cheeks, exposing the tighter opening.
A growl escaped his throat at seeing it so small and closed, waiting to be opened.
"So tiny... how will it take me?" he murmured, his tone full of adoration and hunger. "But you will. Because every part of you belongs to me."
His tongue descended immediately, licking with devotion. First a soft touch, then wet circles. He delighted in every involuntary spasm from Muichiro, every muffled moan from his throat. He plunged his tongue in, penetrating him slowly, preparing him patiently while holding his hips to keep him from escaping.
When he felt him tremble, he added a thick finger, pushing gently. The body gripped him tightly, so narrow it seemed impossible. Kokushibo closed his eyes, aroused to madness, and added another finger, moving them slowly to stretch him.
Muichiro moaned in his sleep, cheeks flushed, murmuring something incoherent.
"Relax..." Kokushibo whispered, kissing his lower back. "I'm just claiming what's mine."
When he deemed him ready, he positioned himself behind and held him by the waist with both hands. He rubbed the tip of his member against the entrance, teasing slowly, coating it with his own fluid.
"Relax for me... let me in" he murmured, voice hoarse with desire.
He pressed firmly. The opening yielded little by little, enveloping him with resistance. Kokushibo groaned low, the sensation of being taken there driving him insane—it was so fragile.
He pushed further, slowly, until fully buried inside.
Muichiro's body arched with a soft sob. He clenched, legs trembling, but Kokushibo held him firmly to keep him still.
"That's it... you did it" he whispered, panting as he filled him. "Now you're mine here too."
He began to move slowly, long thrusts that opened him again and again. The opening gripped him with almost unbearable force, drawing hoarse growls. Muichiro moaned softly, burying his face in the fabric, his body reacting even without waking.
Kokushibo worshiped him with every word.
"So small... so beautiful... you clench as if you'll never let me go. You were born to belong to me, Muichiro."
He quickened the pace, thrusts hitting deeper, drawing sleepy whimpers from the boy. He grabbed his arms, pulling him up so he sat on his cock, back against his chest. He thrust even deeper like that, holding him tightly while one hand touched his stomach.
The small body trembled in his arms. In his sleep, Muichiro reached another orgasm on his stomach, sobbing. Kokushibo held him, kissing his neck and shoulder, without stopping.
"That's it... your body obeys me," he gasped against his skin. "I'll give you so much you'll always remember me, awake or asleep."
Finally, with a groan, he filled him again deep inside. He didn't withdraw, keeping him seated on his member, sealing the tight interior.
He hugged him tightly, caressing his stomach and kissing his hair.
"Sleep well, my little one... there's not a single part of you that doesn't belong to me now."
He held him gently, satisfied, as Muichiro's body rested in his arms, completely his, still trembling softly, full and marked, his breathing irregular from the pleasure he'd received.
Little by little, Muichiro's eyelids fluttered open. His eyes glistened, misty, blinking several times until focusing on Kokushibo's six eyes gazing at him with possessive devotion.
"E-eh...?" he whispered sleepily, still half-asleep, confused.
The demon hugged him tighter, stroking his back.
"Relax, little one. You're with me."
Muichiro looked down, and suddenly his face turned red: he was seated on Kokushibo's member, still inside him, his body wet and sensitive. The mix of surprise, embarrassment, and arousal made him shudder.
"W-what... did you do to me...?" he murmured, trembling, voice low.
Kokushibo tilted his face and kissed his forehead.
"What I should have always done. I claimed every part of you. I filled you until your body understood. Now you're completely mine." His voice was deep, husky.
Muichiro moaned softly, his small hands hugging his chest as his body reacted to the contact.
"It hurts a little..." he whispered, eyes full of tears, breathing ragged.
Kokushibo caressed his face and lowered his hand to his stomach, where he was still full.
"I know... you're sensitive because I've filled you many times. But your body is so beautiful like this, trembling just for me."
He kissed him softly on the lips, then on the nape, while helding him firmly, moving slowly, making sure he felt every inch.
Muichiro whimpered, resting his forehead on his shoulder, lost between shame and pleasure.
"Tell me, Muichiro... who do you belong to?" Kokushibo whispered, his deep, low voice vibrating in his chest.
The boy trembled, flushed, and finally whispered.
"To you... I'm yours..."
Kokushibo was satisfied and pushed him to the edge again. Muichiro cried and moaned between sobs, completely overwhelmed, his body still responding.
When Kokushibo finally came inside him once more, he held him again, covering him in kisses.
Muichiro, exhausted, buried his face in his chest. His eyes glistened, but a faint smile formed on his lips, accepting it.
"It's okay with me..." he whispered before closing his eyes again, letting himself be held and drifting back to sleep.
"Sleep well, little one."
