A/N: Whoever guesses what's missing gets a shoutout
Enmu was on his phone, watching TikToks and lying in bed. He had been coming across slideshows with NSFW implications, and he couldn't stop thinking about them involving him and his boyfriend, Muzan.
It was making him grow uncomfortably hard.
Muzan wouldn't be home till who knows when, but hopefully, it was soon, as Enmu was having a hard time trying not to pleasure himself.
He turned his phone off and set it face down on the nightstand.
Enmu rolled onto his stomach and bent his knee so it was by his torso. He started to slowly grind on the mattress.
Soft pants filled the room as Enmu continued to grind on the mattress, chasing after a pleasure he knew if he got, he'd be punished for, so as he got close, he'd stop for a few moments before starting again.
Enmu froze when he heard the door to their room open. He pushed himself to sit upright to see Muzan walk in. Enmu would've smiled at his boyfriend if he hadn't seen the glare on his face.
"Everything okay my love?" Enmu asked as Muzan sat next to Enmu.
Muzan let out a sigh and shook his head.
"Wanna talk about it?"
Muzan shook his head again and gestured for Enmu to sit on his lap. Enmu nodded and straddled Muzan's lap. They always sat like that unless stated otherwise.
Enmu kissed Muzan's forehead and then rested his chin on his boyfriend's shoulder, trying to ignore his boyfriend's growing boner, which only made Enmu excited, but also curious as to what he was feeling.
Muzan shifted underneath Enmu, which brushed Enmu's cock in a way that caused the smaller demon to softly moan.
"Slut," Muzan hissed.
In the blink of an eye, Enmu's back was against the bed while Muzan was standing between Enmu's legs.
Enmu wasn't sure if he should sit up or not, so he stayed down, watching as his master crawled on top of him.
Closing his eyes, Enmu knew what his master wanted. He exposed one side of his neck, letting out small moans as his master bit and licked the exposed flesh.
Muzan pulled away, admiring his work. He gently grabbed Enmu's chin and turned his head to the other side. He went back to biting and licking Enmu's neck, smirking as he felt the smaller demon squirm under him, aching for more.
He always enjoyed teasing Enmu, but there was no time for that tonight.
Muzan pulled away and placed his hands on Enmu's hips, tailing them to his waist, knowing it drove the smaller demon crazy. He moved his hands back to Enmu's hips and gently tugged at the fabric of his pants. It didn't take long for Enmu to realize that Muzan wanted the pants off as he was scrambling to unzip them and take them off.
Once Enmu's pants were off, Muzan leaned forward.
"Open your mouth."
Enmu listened and opened his mouth, sticking his tongue out. Muzan placed two fingers in the smaller demon's mouth, and before Muzan could speak, Enmu was sucking on his fingers.
"Good slut," Muzan said, watching as Enmu's eyes rolled into the back of his head at the praise. Muzan knew Enmu was trying to get off before he came home, but he was feeling merciful tonight and decided not to punish him.
Muzan pulled his hand away from Enmu's mouth and moved it down to Enmu's hole. He prodded at the entrance, watching Enmu squirm and whine underneath him.
Muzan slowly pushed a finger into Enmu, waiting for him to relax before moving his hand.
Muzan started thrusting his hand, watching as Enmu squirmed and panted.
"I'm not even properly fucking you, and you're already a mess for me, how cute," Muzan purred as Enmu hid his face in embarrassment.
"That won't do," Muzan tsked, bringing his free hand to pin Enmu's hands above his head. He pressed another finger into Enmu, causing him to let out a high-pitched whine, watching as his eyes rolled back in pleasure for a second time.
Muzan added a third finger and started looking for his boyfriend's prostate.
"Right there my lord, right there," Enmu nearly screamed. Muzan smiled to himself and removed his fingers. He took off his pants and underwear. His dick sprang out and nudged Emnu's hole, making him moan and spread his legs further.
"Whore," Muzan hissed. Enmu weakly whimpered. "Lube," Muzan added.
Enmu handed Muzan their bottle of lube. Muzan took it and lubed himself up, groaning at the feeling as he hadn't touched himself in a while. He also added some lube around the rim of Enmu.
"You ready, baby?" Muzan asked.
Enmu nodded.
"Use your words, darling. I know you can do it."
"Please, my lord," Enmu panted.
"Please what?"
Enmu groaned due to now getting what he wanted. "Please, fuck me."
"That wasn't too hard now, was it? That's all it took," Muzan praised, groaning as he pushed himself into Enmu, watching as his boyfriend moaned at the feeling.
Muzan started thrusting, at an agonizingly slow pace, watching to watch Enmu squirm and hear him beg.
"Faster, please, my lord," Enmu panted.
"Why should I?" Muzan asked.
"I've been good while you were away, I promise. Don't good boys get a reward?" Enmu pleaded. Muzan knew he was telling the truth as when he did try to make himself feel good, he never came. That was good enough for him.
"Good slut," Muzan said, suddenly going faster, watching as Enmu relaxed and moaned a symphony for him, and only him. Fuck, Muzan was so lucky to have such a loud boyfriend.
Muzan started going a bit deeper, aiming to hit Enmu's prostate.
Because Muzan wasn't pinning Enmu's hands down, Enmu could cover his mouth if he wanted to, which is what he did. Muzan frowned and stopped mid-thrust. He grabbed Enmu's hands and pinned them over his head.
He leaned down to Enmu's ear and whispered: "I want to hear all the sounds you make, am I understood? Use your words."
"Yes, my lord," Enmu whined, clenching around Muzan, causing Muzan to softly groan.
"That's what I like to hear," Muzan said, thrusting faster than he was before the pause. Enmu moaned in surprise, which then quickly turned into a moan of pleasure.
"You feel so fucking good," Muzan said, moving one hand to Enmu's waist.
Enmu whined and then loudly moaned as Muzan hit his prostate. Muzan made sure every thrust was hitting his prostate.
Enmu moaned loudly when Muzan grabbed his dick and thumbed the tip, smearing precum all over the tip. He started moving his hand in time with his thrusts. It wasn't long after Muzan started pumping the smaller demon's cock, he came.
"That didn't take long," Muzan chuckled as he slowed to a stop, watching Enmu's face turn red in embarrassment. "I'm not done. Think you can handle more?" Muzan asked, removing his hand from Enmu's dick.
"Yes, my lord."
"That's good, whore," Muzan said, starting to thrust. Enmu whimpered. He could feel Enmu clench around him, and fuck it only brought him closer to his finish.
It didn't take long for Muzan to finish inside Enmu, which made Enmu cum a second time, but instead of it spurting out, it leaked out. Muzan pulled out of Enmu and walked to the bathroom, where he grabbed a rag and cleaned himself off.
He walked back to the bedroom and found Enmu asleep. Muzan knew he had used his blood demon art.
Making sure to be careful, he cleaned Enmu off.
Muzan crawled into bed next to Enmu and pulled Enmu into his arms.
It would be a while before Enmu woke up.
