Taste of Eternity - 🖤Muzan✖Tanjirou🖤

⚜ Chapter Sixteen ⚜

This is the final chapter. Just some fluff and smut for Tanjirou and Muzan. Takes place in the future, so enjoy!

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Tanjirou hummed slightly as he wandered through the street. Over a hundred years had changed things drastically. He'd not lie in the sense that his anger had ceased to exist. Eventually society had become as he desired. The world knew about those monster lurking in the dark, not that he minded. It kept them under control. After all, Muzan ruled all. Every human knew who to bow to, who to cower to. It was just the way the world was. Those humans lived in the dark, each morning waking with fears of the present eve. 

Slipping past the dimmer buildings, he slipped into the forest area before stepping into the entrance that would bring him home. Bags hung from his arms, mostly stuff he'd gotten for free. Benefit of fear factors. Landing on the pad, he noticed another meeting was taking place. In all the years, the Uppermoon still existed. A few had been replaced at points, once they decided enough with enough. The ones that turned their back on Muzan got no remorse, by Tanjirou himself. He'd slaughter anyone who dirtied his beloveds name. 

"You're back Nii-chan! How was town?" Tanjirou focused on his sister, handing her the bags as he smiled. 

"It was like normal, quite dead. Not a soul in site, beyond the shop keeper." She snickered before searching through the bags and walking off. Tanjirou watched silently, noticing Giyuu meeting his gaze. The older Demon smiled, a sight Tanjirou enjoyed. Since becoming a Demon, Giyuu was more emotional. He showed his emotions openly, mostly revolved around being around those he considered important. Those he saw as family. He'd opened up to the Uppermoon pretty quickly, befriending Akaza and Uppermoon 1. Douma, of course, was his least favorite. But that was expected. Not many liked that Uppermoon, besides Tanjirou, though it was solely tolerance. Muzan had been in conversation before noticing Tanjirou. He dismissed the others quickly, most knowing what it meant, especially those who have been around long enough. 

"Welcome back Tanjirou. I see the survey was successful?" Tanjirou hummed, approaching the Demon King as he sat on the other's lap.

"I didn't find any leads, but the organization is hidden somewhere on the east coast. It's quite entertaining seeing them struggle, even when it's hopeless." Muzan chuckled, his fingers grazing the younger Demon's chin. A soft kiss grew between the two before Giyuu and Nezuko coughed slightly. Tanjirou smirked as Muzan pulled away.

"Can't you guys take that to the room?" 

"Nezuko's right. I'd prefer not to witness my brother being manhandled..." Tanjirou laughed loudly as Muzan smirked.

"As you wish. I'll have him back to normal by dinner." They both gave doubtful looks as Muzan rose from his seat, carrying the other Demon with him. There was not a word said, mostly due to Tanjirou being okay with whatever followed. He was Muzan's. 

The two wound up in the room where many memories were. Upon being laid on the bed, he noticed Muzan glance him over. His fingers caressed Tanjirou's chest lightly, undoing the buttons slowly and calmly. It left anticipation to build in the smaller Demon. Eventually the top was undone, tossed to the side as Muzan inspected each detail of the other. Fingers glided carefully along pale skin, snagging the waistline of the pants. Gracefully, he pulled them off as Tanjirou grew slightly redder. He was never truly ready to reveal himself. It was always a lingering embarrassment. 

"You know, you're truly beautiful. Only you Tanjirou, are perfect." Those words lit a fire as Muzan worked off his own clothes, his mouth meeting the other's in a passionate kiss. It began soft, easing into a more deep and sloppy one. Tanjirou had shifted his legs, willing access whenever desired. He moaned softly as a finger slipped in, easily moving about. As a Demon, being rough was no issue. Even so, Muzan desired to never hurt him. Even if he could heal, he treasured the other's body. Tanjirou breathed in as Muzan jumped from one finger to three, quickening the process. His patience was slipping, that much Tanjirou knew. He was stretching him without hesitation, desiring to connect. It was endearing to Tanjirou.

"You should be fine Muzan. I will be fine, okay?" The other hesitated, but knew he was only able to bear so much. Removing his fingers, he broke the kiss before raising the Demon's legs to his shoulder. He positioned close, entering without warning. The instant deepness took Tanjirou's breath as he shuddered, movement sending his nerves to life. He could feel each time the tip hit his sweet spot, causing a chorus of moans and gasps. It was music to Muzan's ears, drawing him to increase his speed and grow more rash. Eventually it was even too much stimulation for Tanjirou. The rough thrusts sent him over the edge, sweat pricking his skin as he tore at the blanket. 

Muzan could only admire the other. Their noises. Their features and expressions. It was all his and he'd give up the world for them. Picking up speed, he could feel his own limits slipping. His breathing was quite shallow, warmth welling up in his stomach. It was almost welcomed, but left his mind on air. His vision was losing focus as he was reaching his peak. As soon as that warmth had begun, it also vanished. It left him and instead invaded Tanjirou, the other tensing as he choked on his breath, raspy breaths leaving him as his head pressed further into the mattress. his gaze was weak, eyelids slightly closed as Muzan steadied his own breathing. Pulling out, he carefully worked Tanjirou under the covers he'd tore at, small holes and rips appearing in places. Muzan slid in beside him, pulling the other close as he relaxed against Tanjirou. 

"I love you Tanjirou, forever and always." Tanjirou, who was drifting in and out, let out a quiet chuckle before turning to face Muzan. He smiled, giving a brief kiss as he spoke with a soft tone. His eyes were showing his love, his admiration and trust. His words were powerful. Lifting Muzan's heart higher and letting it soar.

"I love you too. I will remain, forever. Until the end of time."
