It was supposed to be a good day but for Rimuru. Unfortunately, he'd gotten himself into an unavoidable situation. After dealing with Milim's "certain situation," Shion, Rimuru's secretary, was kowtow in front of Rimuru, begging him to clean her navel as well. "Please Lord Rimuru, can you clean it for me?" He felt quite anxious seeing her kowtow in front of him. "Shion, there is no need for you to do that." She kept doing that. "Please stand up, Shion." She slowly stood up from her position and said, "As you wish Lord Rimuru." He felt relieved after successfully calming down her. "So Shion," he said as he jumped to the coach from the floor and looking straight up to her face. "Can you explain why you want me to clean your navel?" "Umm Lord Rimuru, it is quite embarrassing to tell you." as she fidgeting her fingers with her blushed face. Rimuru couldn't help but think she was being a little childish. "You're kidding, right, Shion? You say that you're embarrassed about your
It was a peaceful day in Rimuru City, even to its ruler, Rimuru Tempest. He was about to take a nap on his couch, after he had finished discussing the future plans of the federation with his executives. After they exited his room, he reverted back to his slime form. As he was about to close his eyes, suddenly a loud footstep that slowly become something faster, barged into his room, knocking back the door and this cause him to wake up due to the loud bang of the door. A pink hair girl tied in twintails appeared before the door and lunged Rimuru at the coach. "Milim?! What are you doing here? Aren't you supposed to be managing your domain?." She hugged him so tightly, as though he were a balloon. Milim, the pink hair girl, was Rimuru's best friend, or "bestie," as she like to call themselves, and a fellow Demon Lord of the Octagram. She frequently visited the Jura Tempest Federation, due to the relationship with her bestie, but mostly she came by to stave off her boredom and sometimes to run away from her work. "Well," Milim said, as she smiled at him. "Carrion and Frey are managing the domain right now, and they said that I can have the day off. So, that's why Im here to hang out with you." "Oh.. I see." Rimuru let out a nervous laugh and gave her an awkward smile. Pretty sure that Milim ran away from her work, Rimiru thought to himself. He'd hoped that Frey wouldn't be nagging at Milim again. Just before Rimuru could respond, Milim picked him up from the coach and held him tightly to her arm. Rimuru wanted object to her but he could not bring himself to upset her. Following that, Milim exited the room and headed to Rimuru City, full of excitement. After they finish hanging out together, they headed back to Rimuru's room. She entered his room and went straight to the couch. She lied down while he reverted back to his human form and went back to his desk to continue his work. As he worked, he took a quick glance at Milim on the couch. She was sound asleep, with a cute snoring sound coming from face. He finally felt some peace now that she was asleep. He took this chance to close his eyes to rest for a while, but he was disturbed when a foul smell came from his room. He try to pinpoint the smell, and it was coming from Milim. More precisely, from her bellybutton. "Hey Milim, ummm your bellybutton really smells." He approached Milim and woke her up by slightly poking her face. "Oh that," Milim said. "It usually smells because of the sweat accumulating in it, and to be honest, I don't remember when is the last time I cleaned it. I usually use wild slimes to do that." As she woke up from her sleep, she yawned loudly while streching her arms. She rubs her sleepy eyes and looked at Rimuru. "Oh, it went deeper again." As she slowly spread open her bellybutton, the accumulated sweat went further in. "Umm.. wild slimes? You mean the wild slime from the forest Milim?" Rimuru was quite shocked to hear it from her. "Yeah. Once a week, I capture a wild slime, and forcefully put them inside my bellybutton. Do you know that they can devour anything? So I try to experiment a litt-" She stop mid-sentence and looked directly at Rimuru with her fire in her eyes. "Come to think of it, you are a slime right Rimuru?" He suddenly got a chill down his spine. He felt something terrible was about to happen but he try to stay composed when talking to her. "Yeah, I'm a demon slime but we still belong to the same species." "Can you help me clean my bellybutton Rimuru?" She grabbed both of Rimuru's arms, like she was about to request something from him. She was looking at him with puppy eyes, but he tried to look away. This became difficult as the brightness of Milim's eyes intensified. "Alright," he eventually muttered, reluctanly accepting her request, albeit only to avoid upsetting her. She then started a cheerful pose as she was jumping excitedly. Rimuru, on the other hand, was kinda nervous from doing this kind of thing. He crouched down to her belly, until her bellybutton was at his eye level. He examined her belly, and noticed that her bellybutton was an innie, and had a cute vertical shape. He was amazed to see her bellybutton up this close, and he was kinda into it. And suddenly, he felt an urged to finger her bellybutton. Without any hestiation, he immediately put his index finger into her deep innie bellybutton and slowly fingered her deep innie. He felt like her bellybutton was slowly swallowing his whole finger. "Hahaha! That's tickle." She let out a cute, giggly laugh. She pulled out his finger from her bellybutton, and requested him to be in his slime form in order to clean her bellybutton. After which, he was free to immediately revert back to his human form. She put Rimuru back on top of the table. "Okay Rimuru I'm ready. My bellybutton is all yours." Rimuru immediately went inside Milim's bellybutton as she spread it open to let him in. He slowly slithered deep inside, until he reached at the end of her bellybutton. His body adapted to its surroudings, and he changed his size to fit inside her bellybutton. At the end of her navel, he then started to clean her navel via vibrating in it. He cleaned every inch of her navel, even her navel knot. His tentacles, like slime, cleaned all of the navel walls, sucking all the type of dirt, lint and even dry skin cells. This causes Milim to feel a pleasingly ticklish sensation. He was having fun cleaning her navel. "This is kind of addicting," Rimiru thought to himself. "I kinda like it in here. Hmmm, how about we tease Milim a little bit." He teased her by tickling her bellybutton from the inside, but she did not know that yet. "Okay Rimuru, I think my navel is clean enough. You can come ou- Hahahaha!" She immediately started laughing before she could finish her sentence. She was holding her stomach with both of her hands. She could not stop laughing that she started to kick in the air. Rimuru was tickling every inch of her bellybutton, even at her navel knot. He was enjoying this moment. Due to her loud laughter, Shion, Rimuru's secretary and bodyguard, quickly barged into his room while holding her weapon by the door. "What happened, Lord Rimuru?! Did someone attack you?" She saw Milim laughing at the floor with both of her hands on her stomach. She slowly approached her and scanned the whole room to find her lord's whereabouts. "Milim, where is Lord Rimuru? Did something happen to him?" Milim tried to stop her laughter and pointed directly at her navel. "What's with your bellybutton," said Shion, with a slightly confused face. She get closer to her navel and examined it, slowly spreading open Milim's bellybutton. "Im here Shion." Suddenly Rimuru pops out from her bellybutton with a "tada" gesture. Shion screamed loudly and passed out on the floor. Milim and Rimuru looked at each other, and of course, he was still inside her bellybutton. They were quite confused as to why she passed out. After a while, Shion woke up on Rimuru's coach and saw Lord Rimuru in his slime form sitting on top of her stomach looking at her with a worried face. She was quite confused as to what had happened just now, and she tried to recall back her memories. She knew she was looking for Lord Rimuru. He tried to calm her down by explaining the situation. "Understood Lord Rimuru, as long you are safe." "Don't worry, I'm still safe," Rimuru said with a sigh of relief, as he patted Shion's head which caused her to blush slightly. "Wow Rimuru," Milim said, interrupting their moment. "Look at my bellybutton and how clean it is. I think you have a talent on cleaning bellybutton and you should use it more often." She was standing opposite of them while examining her navel, fascinated by how her navel was sparkly clean, even the deep inside. "Look guys! Look how at clean navel. And it smells nice, too." As she said this, she spread open her navel and displayed its innards to them. They were quite fascinated looking at her navel, but it was different for Shion. She gave an envious look to Milim's bellybutton, but she tried to hide her expression as Rimuru was looking at her. "Anyway Rimuru, thanks for helping me clean it up. I gotta go now before Frey starts to lecture me again. Bye guys, see you tomorrow." As she bid her farewell, shw quick darted out of his room with a trail of wind behind her, leaving both of them dumbfounded. Suddenly, Shion asked a sincere request for Rimuru. "Lord Rimuru, can you please clean my bellybutton as you did with Milim?" As she slowly unbutton her shirt that reveals her midriff and navel. He was quite shocked to hear it. Gimme a break please, he thought to himself.
