Chapter Text
"Today, Rimuru, the new Demon Lord... I bestow upon you the wonderful privilege." Guy smiled at Rimuru as he threw the responsibility of renaming the Demon Lords to him. Rimuru smiled an awkwardly polite smile as he refused.
"I don't need it, so I refuse the offer." The two kept smiling at each other as everyone else looked on impassively. Suddenly They all moved back as Guy sliced the table in half with a wave of his hand. Slowly, yet seductively, he sauntered up to Rimuru as he spoke.
"I know you do. I'm giving you the power..." Rimuru sweatdropped as the Demon Lord got closer. "To provide our new name. This is such an honor. Surely you'll accept it right?"
Rimuru had no choice but to turn his head as the other kept walking closer and closer until he was close enough to grip his chin. Rimuru felt confusion as his head was turned to look up at the older Demon Lord. Guy continued his speech as he lowered his face to the slimes ear. "...I mean... the reason why we are doing this is because you reduced our numbers."
Rimuru didn't know if he could feel pleasure at all but the feeling of Guy's lips right up against his ear sent shivers down his neck. Then he felt teeth chomp down onto his ear and that gave him goosebumps. To get away he finally relented.
"Alright, I get it!" He slumped forward in his seat feeling a deep blush cover his cheeks. "Don't complain if you don't like it, okay?"
(Skip Ahead...)
Rimuru had renamed the Demon Lord Alliance to 'Octagram' which no one was opposed to. They discussed the territories and the ex-Demon Lord Kazaream but when it was time to leave Rimuru found it hard to keep awake as the Demon Lords all left except one who stood silently watching as Rimuru fell unconscious.
Guy placated Rangar and Shion informing them their master would be returned unharmed and though the two wanted to argue they realized there was nothing they could do against one of the strongest Demon Lords.
Rimuru came to, slowly taking in his surroundings. He was in what seemed to be a bedroom made of ice. Confused, he sat up trying to leave the bed to explore, stopping short as he noticed his clothes had been changed. He was only left with a long-sleeved white shirt that went down to his thighs.
"What the hell!!" He fell from the bed in shock. Sure, he didn't have a gender so there wasn't anything to hide but it was still embarrassing to have no underwear on. Whoever had taken him must've been a pervert.
"So you're awake, finally." He recognized Guy's flirtatious voice as the man came into view where he had fallen. He quickly pulled the edge of the shirt as low as he could lowering his head as he blushed. "There's no need to hide. Who do you think undressed you?"
"W-why am I here?!" He shot up as he yelled. Not giving care as the shirt rode up higher exposing his smooth thighs. "Where are Shion and Rangar?!"
"Hmm..." Guy crept closer circling to Rimuru's back as he laid a hand on those slim shoulders. "They went back to Tempest."
"Hey!" Rimuru was easily picked up and deposited onto the bed again.
"Have you not noticed any changes?" Rimuru gave a confused look as the other came to sit between his legs.
"Look." That was all Guy said while he directed his hand to where Rimuru's private parts should've been if he had any. Rimuru gasped as he felt a spark shoot through him. He had masturbated before but this felt completely different from that. "I gave you a special gift. Do you like it?"
Rimuru gasped as he rested his hand on the hand pleasuring him. "What is that?"
His voice trembled as he struggled to pull Guy's hand away but the other was having none of it. "You're a female now. Well, only temporary."
Shivers went down his spine has as Guy's breath brushed against his lips. His legs unconsciously slid open as he tried to rock to the rhythm of Guy's hand movements. "Why?! AH!"
"You were so much fun in Walpurgis, I decided that it was too early to end things there. Don't you agree?" He slowly tried pulling his hand away but Rimuru's hand whose purpose was to push his hand away kept it where it was. "I see you are enjoying yourself."
Rimuru was in a trance. The feeling between his legs was so new to him. It felt electrifying. He didn't want it to stop, he was just so close. Guy used his strength to pull away as he positioned his mouth this time to suck on Rimuru's clit.
"You don't taste like anything at all. Is it because you're a slime?" Rimuru hissed as Guy nipped him sharply.
Guy stripped himself of his pants as he got ready to penetrate the willing body under him. Rimuru, having been too much in a trance to really put up any resistance, moaned as he felt something stretching my virgin hole. There was no pain as he was thrust into.
"You seem to enjoy this a lot. I'm glad. Then why don't you do the work?" Guy flipped them over so Rimuru was on top. With a smack to the Demon slime's ass, he said, "Start moving."
"W-what?!" Rimuru felt his cheeks burn from embarrassment as he was forced to willing take pleasure from another man's dick. He had died a virgin and as a slime thought he would always be one. 'Who would have thought I'd get my virginity taken by a dude?'
Guy smirked as Rimuru started moving. Pulling his body up and letting gravity pull him back down with a loud smack! Guy slid his nails down Rimuru's thighs slowly, enjoying the feel of being inside him.
Rimuru moaned. It was confusing. He shouldn't have the ability to feel anything yet he felt so amazing at the moment. His hips stuttered as he felt an incredible amount of pleasure coming along. Guy laughed softly then turned them over to have him finish. Then he was coming.
"Hmm, that was fast." Rimuru gasped as the Demon Lord above him kept thrusting. "I haven't finished yet. Guess we're gonna be here a while.
