Douma flirts with Kokushibou, Muzan is pissed

A/N: I didn't know what to name this, oopsie.

Muzan was walking through the infinity fortress in search for his beloved, Kokushibou. He called upon Nakime. "Nakime, teleport me to Kokushibou," she gulped softly. "Muzan-sama, I don't think you'll like it," Muzan raised an eyebrow and put a hand on his hip. "Nakime, send me to him," she nods softly and teleports him to Kokushibou.

Muzan turned around and clenched his fists. He saw Douma with his arms wrapped around Kokushibou's neck. He looked down before Douma's head was ripped off his neck, Muzan's hand holding the decapitated head in his hand. "Douma, what the hell do you think you're doing with my boyfriend?" Douma giggled. "We're just playing, Muzan-sama!" Muzan scoffed and threw his head away before turning towards Kokushibou.

He grabbed Kokushibou and walked towards their room. "Muzan-sama?" Kokushibou gulped softly. Muzan turned to Kokushibou, veins on his forehead. "What the hell was Douma doing?" he asked as he crossed his arms over his chest in annoyance. His red eyes narrowed as he thought of the scene of Douma flirting with his lover.

Kokushibou gulped softly, trying to remain calm despite the situation. "I... I'm sorry, Muzan-sama," he bowed his head deeply, his face pale from fear. "I didn't mean to cause any trouble..." Muzan sighed heavily, looking into Kokushibou's eyes.

Muzan spoke again with a quieter tone. "Kokushibou, the next time Douma does that, slice his head off. It annoys me when he's near you," the shorter said, rubbing his temples. "Muzan-sama, but..." Muzan cut him off with a fierce look. "It's not a request," he growled lowly. "But... if you ask, I will do that for you," Kokushibou said with a soft smile, taking Muzan's hand.

Muzan let Kokushibou grab his hand. "What are you doing?" he asked, raising an eyebrow. Kokushibou smiled sweetly, squeezing Muzan's hand gently. "Just being affectionate," he whispered quietly. "Is there something wrong with that? You seem tense," Kokushibou chuckled lightly, leaning closer to kiss Muzan's cheek.

Muzan grumbled softly. "Mmm... Sit down, I want to try something," Muzan hummed. He wanted to show Kokushibou that he is Muzan's and no one else's. Kokushibou sat down obediently, looking up at Muzan expectantly. "Anything you wish, my love," he murmured, kissing Muzan's cheek.

Muzan walked inside his closet, a few minutes later, he walked out. He wore lingerie, it looked expensive. It was white, it had a bra, panties, the typical, with a sort of jacket. It looked very beautiful, especially on Muzan.

Kokushibou stared in awe as Muzan changed into lingerie. "My God, you look so beautiful like this!" Kokushibou gasped, staring at Muzan. "Thank you for making yourself so pretty for me," he said, blushing slightly.

Muzan hummed as he sat on Kokushibou's lap. He ran his hands over Kokushibou's muscles, humming softly. "You are mine, understood?" he said with a light hiss. Kokushibou nodded eagerly, wrapping his arms around Muzan tightly. "Yes, yes. Of course I am yours," he replied breathlessly. "I belong only to you." He kissed Muzan passionately before pulling back slightly. "And now, I'm all yours," he added huskily.

Muzan hummed as he slowly took Kokushibou's top off. After he took it off, he folded the piece of clothing. He slowly traced over all of Kokushibou's muscles. Kokushibou shivered in pleasure as Muzan touched every inch of his body. The sensations were overwhelming and made him feel weak in the knees. He leaned forward, pressing his lips against Muzan's neck. "Please continue..." he whimpered, unable to take much more of the exquisite torture.

Muzan moaned softly before standing up. He took Kokushibou's hakama pants off and his fundoshi, revealing his big dick. Muzan licked his lips. Normally he'd suck Kokushibou off, but he was pissed and skipped it. He simply pulled his panties off, nothing else. He grabbed Kokushibou's dick with a smirk before starting to stroke it.

Kokushibou moaned as Muzan lubed his dick. The friction felt amazing and only made him hungrier for more. He pressed his hands against the table, gripping tightly. "Muzan... Fuck," he groaned as Muzan gave him a handjob.

Muzan smiled as he continues to stroke Kokushibou's dick. "Mmm~" he purred softly. Kokushibou could barely contain himself anymore. Every touch sent waves of ecstasy through his entire being. It seemed like forever since he last came and yet here he was again, begging for release. "Please... please hurry..." he begged desperately. "I can't hold out any longer..."

Muzan pulled away with a grin. "No, you won't cum without my permission," he growled. "For punishment, you will watch me finger myself, and don't you even think of getting up," he commanded with a smile.

Kokushibou couldn't help but moan in frustration as Muzan denied him. "Why do I have to be punished?" he whined, looking down at his dick which was throbbing painfully. "Because you let Douma flirt with you. It's almost like you liked when he did so," he said with a slight scoff.

Kokushibou looked up at Muzan, his face turning red from embarrassment. "No, Muzan-sama. I apologize for letting him, I will do better," he said sincerely. "Good," Muzan smiled before grabbed the lube and pouring it over his fingers. Muzan smirked as he started to finger himself, moaning Kokushibou's name. He knew Kokushibou liked to watch him when he'd do such things.

As Muzan started to finger himself, Kokushibou couldn't help but stare in awe. His heart was pumping so hard he thought it would burst out of his chest. He wanted nothing more than to reach out and touch Muzan's body, but the punishment stood firm in his mind.

Muzan kept moaning Kokushibou's name, his back lightly arching. "Ah~ Kokushibou!~" he moaned, a light smirk on his face. Kokushibou watched intently, unable to look away despite wanting to. The sight of Muzan fingering himself had made him incredibly horny and aroused, and now watching him pleasure himself only served to increase his arousal further.

His breathing became heavy and shallow, and he could feel sweat dripping off his forehead. Kokushibou watched intently as Muzan fingered himself. The sight made his cock twitch. "Muzan-sama..." he breathed heavily. He didn't know how much more he could take.

Minutes that felt like hours passed. Muzan panted softly as he walked closer, sweat dripping from his face. He put his hands on Kokushibou's shoulders. "Don't cum unless I say so, understood?" Kokushibou nodded quickly, his eyes wide with anticipation. He couldn't believe what he was about to do, but he trusted Muzan implicitly. "Yes, Muzan-sama," he replied breathlessly. He shivered slightly, feeling nervous but excited all at once.

Muzan smiled as he lowered himself on Kokushibou's cock, groaning as he was penetrated. "Ah~! Hah!~" Kokushibou gasped as he felt Muzan's warmth surrounding his cock. He was so hard he felt like he would explode. "Ah... Muzan-sama..." he moaned heavily. As they started to move, Kokushibou couldn't believe how perfect it felt.

Muzan's hole clenched around Kokushibou's cock, his own twitching as he bounced up and down. "Fuck~! Ah!~" he groaned. Kokushibou felt his heart racing as he fucked Muzan. He could feel the pressure building up inside of him, and he knew that it was only a matter of time before he was going to cum. "Muzan-sama, I'm gonna... I'm gonna cum~!"

"No... Don't cum..." Muzan stopped bouncing, smirking at Kokushibou. "You don't have permission to cum." Kokushibou whimpered in frustration. He wanted nothing more than to release everything he had into Muzan's tight ass. But he knew better than to disobey Muzan. Instead, he tried to hold back his orgasm until Muzan gave him permission. "I understand, Muzan-sama.."

"Good boy," he smiled and kissed Kokushibou on the lips, wrapping his arms around the taller's neck. Kokushibou moaned softly into the kiss, his cock still trapped between Muzan's ass. He couldn't help but feel his own orgasm growing closer and closer, but he refused to let himself cum yet.

Muzan started to bounce again, his back arching as he mewled. "Ngh~!" he gasped. "Hah!~" Kokushibou watched intently as Muzan rode him, enjoying every second of their lovemaking. His breathing became heavy as well, sweat dripping from his forehead onto Muzan's shoulder. "Ah... Muzan-sama..." he panted out breathlessly. "Please... please keep going..."

Muzan kept bouncing, his tits softly bouncing. Muzan couldn't help but keep on moaning. "F-fuck~!" he felt close. He kissed Kokushibou, their tongues wrapping around each other as Kokushibou's hands were on his beloved's thighs, helping Muzan ride him.

Kokushibou groaned as they French kissed. He helped Muzan bounce on his cock, hoping that Muzan would let him cum inside him. Muzan pulled away, smiling. "I-I'm close... Cum with me, baby..." he panted, gasping softly.

Kokushibou nodded eagerly, wanting nothing more than to fill Muzan up with his seed. With one final thrust, he came hard, shooting load after load deep inside Muzan's ass. "Ahh~!" he cried out loudly, feeling like he was about to pass out from pleasure.

Muzan came, arching his back. "Mmm!~" he purred softly as he got off of Kokushibou's cock, grunting when he couldn't stand. "Fuck..." he mumbled, gripping the bed tightly. After a few minutes, Muzan slowly got on the bed. Kokushibou laid his head against Muzan's chest, his entire body covered in a light sheen of sweat. "That was amazing..." he said softly, not believing that he had just gotten to fuck his beloved's ass.

Muzan smiled softly and lay his head on the pillow as he stroked Kokushibou's hair. "K-koku..." he yawned softly. "Don't talk to Douma again, okay?" he mumbled. "I promise. I'll stay away from him... Forever," he whispered softly, kissing Muzan's chest. He couldn't believe that he had just come inside Muzan's ass, and he couldn't have been happier. He felt like he was the luckiest man in the entire world.

Muzan hummed, yelping when suddenly their positions were changed, Muzan now laying on top of Kokushibou's chest. "Mm?" Kokushibou looked down at Muzan curiously. "What are you doing?" he asked gently, running his fingers through Muzan's soft black locks. "Are you tired? Do you need some rest?" he murmured, rubbing Muzan's shoulders.

Muzan simply nodded as he closed his eyes, slowly falling asleep as Kokushibou massaged his body. Kokushibou watched over Muzan until he fell into a deep sleep, then he wrapped himself around Muzan, pulling him close so that they could both feel each other's warmth. He held onto Muzan all night long, never letting go.

They had both fallen asleep in each other's arms, Kokushibou loved Muzan, so he stayed away from Douma to please his lover. He'd do anything for that man.
