A/N: THE FIRST OF MANY!!!! Of course, it seemed like someone suggested the yaoi-ship from my other Tensura story that I am writing, so I felt that it was appropriate to satiate that one first, also it seemed like the easiest to write at the moment. Anyways, let me know what you guys think, and leave your requests or suggestions in the comments below! Remember, Rimuru can be a Boy, Girl, or even have both traits of both genders (A.k.a.- Hermaphrodite or Intersex). This is new, I've never written a Yaoi type of thing before, so let me know what you think, let me know what things I can improve on in terms of spicy Yaoi stuff, and I hope you enjoyed. Thanks for reading.

You and your long time friend, Satoru, now known as Rimuru both died on earth and reincarnated as monsters in this new world where you both aimed to create a peaceful and relaxing place to live where everyone could be at peace. Through hard work and many battles, the two of you created a new nation called Tempest and ruled together as leaders, making friends with incredible monster races and even humans. The two of you even evolved into True Demon Lords and attained power to be recognized by not just other Demon Lords, but other leaders of nations around the world in order to keep them from bullying your new nation. Just recently you and Rimuru had fended off the Western Holy Church and even made amends with their strongest warrior, Hinata Sakaguchi, and their Demon Lord, Luminus Valentine, due to this conflict occurring over misunderstandings and being set up by a third party. With new relationships made between yours and their nation, a night of celebration occurred along with heavy drinking of alcohol and other various boozes. Thanks to a trick you and Rimuru learned from Demon Lord Luminus, the two of you were able to negate the poison resistance skills you both had and were able to drink yourselves into a heavy stupor. It was safe to say that Rimuru couldn't make it back to his home from the celebration area, however, your house was much closer as you offered him the opportunity to stay the night. Not even thinking twice or sensibly, Rimuru agreed as you two stumbled back to your home only dressed in men's yukatas as the two of you were chuckling and giggling as you clamored through your front sliding door and fell on your wood floor laughing.

"Ahahaha~! Drinking is just as fun as I remember~!" Rimuru giggled while sprawled out on the floor.

"Right~?" You chuckled as you rolled over to get up, but suddenly.

"Agh~" You heard Rimuru make a strange noise as you tiredly opened your eyes to see a stunning sight.

You accidentally pinned Rimuru to the ground under you as your hand pinned down his wrist above his head while his other hand hovered around his chest nervously. With both yours and his new looks, you two were undeniably attractive and the situation didn't help as your yukatas were beginning to come undone. The slit of your yukata slipped a bit, revealing your manly chest, while Rimuru's yukata was coming undone everywhere, exposing his slim and sleek legs while his top part had completely undressed, revealing his petite chest and stomach. Rimuru's androgynous look did not help as in your eyes looked like a snack with how defenseless he seemed, and in his eyes, you were absolutely breathtaking. Without uttering a word, you suddenly leaned down and planted your lips on his, taking him by surprise as he flinched and fidgeted around under you.

"W-Wait—Mmph~! Y/N! W-We're...!" Rimuru kept getting silenced by your kisses as you even added some tongue before pulling away, leaving small a trail of spit between you both. "We're both male..." he said in a bashful manner, but that just made him even more cute.

"So?" You said in a husky tone that made Rimuru's eyes sparkle. "Ever since we reincarnated here, we've changed. It's only natural that our sex drive be a little different. Are you saying you don't want to?" You asked as you gently placed your hand on his thigh and traced circles around his upper thigh, making him squirm.

"Ngh~!" Rimuru suddenly moaned.

"I can't remember the last time I did anything sexual, and I've been pent up for a long time. Boy or girl, it doesn't matter. Because tonight..." You trailed off as you leaned in close to his ear. "...I won't let you sleep." You whispered as Rimuru's rationale flew put the window as he submitted to being your plaything this one time.

"O-Okay..." Rimuru whimpered as you pulled back to see a completely lustful look in his eye as he hufffed excited breaths from his smile. "Let's go crazy~!" He exclaimed as you felt something press against your crotch.

With a hungry growl, you forced your lips onto his again as he moaned into your dominating kiss. Your tongues were doing a dance as Rimuru wrapped his legs around you and began to grind his body into yours, letting you feel his bulge rub up and down against yours. You picked yourself and Rimuru off the floor as the top of his yukata came undone fully, exposing his petite upper body as you moved your head down and began sucking and biting him on the neck and shoulders, marking him. Rimuru, in his drunk stupor, didn't heal the wounds as he wasn't thinking straight, and the marks remained as you stumbled through your house, pressing him against wall after wall as he moaned like a girl.

"Y/N! Please!" Rimuru mewled as you grabbed him by his butt with both hands and looked to see him drooling from the mouth. "Let's do it already." He begged as you bit and tugged on his lower lip, making his eyes roll back slightly as you slid your hands under his yukata and began squeezing his butt.

Your slime buddy was beginning to get so hot you thought he might melt in your hands, but thankfully he didn't as you finally made it to your Japanese styled room and walked across your tatami floor before landing on your futon with Rimuru on top. Rimur also couldn't wait as he had his hands all over you, practically tearing away at your yukata as your tail wrapped around behind him and began massaging his butt crack, slowly getting him used to spreading his cheeks. Rimuru would stop kissing your lips and run his tongue down your body as he undid the cloth tie that was keeping your yukata close and opening it fully to reveal your glorious penis that you obtained with this human form. With Rimuru's newly attained sex drive and preferences, he was astonished by the sight of your cock as it was stood tall at about nearly 9 inches. He was so amazed at the sight that he froze and frustrated you, prompting yourself to grab his head and shove his face against it, making him get a nice whiff and feel of your dick. Rimuru was breathing hot and heavy breaths across your shaft, making you more horny as your cock twitch on his face. The slime leader of Tempest opened his mouth as he gave you an excruciatingly long and sloppy lick from the base of your cock to the tip, before hovering his mouth over it to let some slime drool fall from his mouth and coat your rod. Rimuru smiled and giggled as he playfully licked around the tip, loving the sight of you squirm around and waiting for him to suck it.

"H-Hey...! Do it already!" You groaned as your eyes pulsed blue in angst.

"What's the magic word—BLURRGGHH!!" Rimuru was caught in sheer shock when you suddenly and violently forced him down on your cock, pushing all the way into his throat.

Even with a slime body, it was humanoid, meaning that he could have or could not have a gag reflex. Much to your pleasure, he did have one as he gagged on your cock with wide eyes as he spat and coughed on it a few times before you let him up again.

"A-Agh! Agh! That...That was...!" Rimuru coughed a few times before looking at you with stars in his eyes. "Amazing~!" He said with his slime spit covering his mouth.

In an instant, Rimuru went crazy and began to devour your cock, slurping repeatedly as he went up and down your shaft as fast as he could. You didn't know if it was because he was a slime or just drunk, but his mouth and throat felt extra slimey as you felt your tip rubbing up and down his throat over and over again. You were in sheer ecstasy as you kept your hand on his head, forcing him as deep as you could make him go. Rimuru would gag and cough on your cock over and over before you suddenly grabbed him with both hands by a few locks of his hair, and began thrusting upward yourself. The gagging noises Rimuru was making sounded off over and over as your crotch kept smacking him in the face before you finally gave one more powerful thrust and released your load. Rimuru wasn't ready as his gag reflex kicked in once again, making him cough up your cum, even sending some shooting out of his nose. He reeled back in a gagging fit as he fell on his back gasping for air while you also fell back trying to catch your breath. After calming down a little, you sat back up and scooched over to see if he was okay.

"I-I'm sorry, Rimuru. I just..." Your words fell short though when Rimuru raised his head with a smile on his face as he looked at you lustfully and wiped his face with his hand.

"Hehe, I guess you held back since we reincarnated, huh? That was a nice snack to have after so many drinks we had back at the party~" Rimuru chuckled as he seductively licked his hand clean of your cum before swallowing and opening his mouth to prove nothing was left.

"You...!" You exclaimed in shock before lunging at him once again.

Rimuru giggled as you two engaged in a hot and steamy kiss once more, using tongue again as this made you get a taste of your own semen mixed with Rimuru's taste. Even though you never imagined yourself doing this, especially with your best friend from your previous life, nothing else mattered except the two of you making each other feel good as you undressed Rimuru fully, exposing his slender build with his smaller 5 inch penis exposed. Rimuru was a bit nervous about showing himself in such a manner, and even thought about altering his body to maybe a female form, but without uttering anywords, you cupped his cheek and made him look at you as he blushed deeply. You pulled him over to straddle you once more as the two of you kissed for a few minutes again, Rimuru unintentionally rubbing his dick against yours before you suddenly turned him around so you both were in a sixty-nine position. Your co-leader noticed how rock hard you were once again and began kissing your shaft over and over as you pulled his hips down and grabbed both his ass cheeks before spreading them, revealing a clean and smooth hole as his penis was resting against your chest. Without warning, you leaned forward and gave his hole a quick lick, making him yelp as he felt a cold jolt run up his body and he tensed up. Wanting to see what other reactions you could get out of him, you began licking around his hole before plunging your tongue inside, enjoying yourself as since he was a slime, he was completely clean and even tasted a bit sweet oddly. Rimuru was trembling at the new sensation as his smaller penis twitched on your chest and his butthole kept puckering around your tongue. 

"Hey...Make me feel good, too..." You complained before going back to eating his rear end out as your cock twitched in front of his face.

"R-Right~...!" Rimuru struggled to speak as he moved his mouth over your dick and began sucking heavily once again. 

The two of you were entangled with one another completely as Rimuru used his hands to massage your balls while his mouth worked your shaft. Remembering that he had two points of pleasure on his lower body though, you decided that it was unfair your cock was the only one being pleasured. Moving your face away from his ass, you shifted Rimuru a bit and lifted him up by his hips a little to lock your sight onto his twitch cock. You never imagined yourself sucking another penis, but since it was Rimuru, you felt that it was fine. Hesitating for only a few moments, you decided to suck up your pride in exchange for pleasuring your best friend as you lowered Rimuru down and opened your mouth, allowing his penis to enter your hot orifice. Rimuru was shocked and came up off your cock to turn his head around to look and see you moving your head slightly while suckling and licking his penis.

"H-Hey! I-I-If you do that, I'll--AGH~!" Rimuru was trembling as he arched his back towards you and began trembling.

Rimuru's penis wasn't as large as yours, so it didn't go down your throat, but you made sure that he would go crazy despite the difference in size as you squeeze your cheeks and wrapped your tongue tightly around his penis, even managing to stroke it just a little with your tongue. Rimuru's face was contorting in different ways as he was even thrusting a little bit into your face, and it didn't help him when you moved your hands back towards his butt and inserted two fingers, slowly spreading them to open his butt a little more. Moments after spreading his asshole, Rimuru couldn't hold it anymore as he unleashed small, but energetic spurts of come into your mouth, and you kept yourself wrapped around his cock as best as you could to make sure nothing was lost. Rimuru twitched above you and the sounds of you gulping down his load were audible as you took a few moments to get used to the taste before swallowing everything. Rimuru collapsed forward and his head rested next to your cock as his penis popped out of your mouth, allowing you to catch your breath. 

"Rimuru..." Your slime buddy heard you call as he was suddenly turned around and pulled up to your face as you kissed him, allowing him to get a taste of himself as your tongues danced with one another again.

"I guess..." Rimuru trailed off as he pulled away from the kiss and smiled at you. "We're even." He said in regards to you both tasting each other's cum and sucking one another's penises. 

"Yeah..." You agreed before suddenly flipping over as Rimuru gasped in surprise and stared up at you in awe as you pinned both his hands down to your futon. "...But, there's still something we have to do." You said as he nodded with his mouth slightly open in anticipation.

"Yeah. Do it..." Rimuru said as he spread his legs wide open and revealed his cute asshole that was lubed previously thanks to your saliva. "...Let's go all out~!" Rimuru exclaimed as you were left with stars in your eyes at how beautiful he was...and how you wanted to sully him entirely.

After hearing him speak in such a way, your kaiju instincts seemed to have kicked in as you lined yourself up and in one swift move, you stabbed your cock into him. Rimuru was about to scream in ecstasy, but you silenced him by shoving your tongue into his mouth as you violently thrusted in and out of his ass. If Rimuru wasn't melting before, he defintely was now as a violent sloshing noise came out over and over again from his ass as your cock was spreading him wider and wider open. Rimuru's penis that was limp moments before had shot up and steeled itself as it flopped back and forth, slapping both his skin and your groin with every thrust. You let go of his wrist and held his hands, interlacing fingers with him as he couldn't even wrap his legs around your waist and they just flailed around in the air. After some thrusts, Rimuru came once again, spreading his load across his stomach as a few splashes hit your body also. The intense fucking session was so stimulating and draining at the same time, that Rimuru's skin slowly began turning blue and began to actually melt a little as he was sinking into the floor. Your dorsal plates were flashing blue and your tail wagged around in the air with excitement as you kept pounding Rimuru into your futon, and you could even hear the wood under the tatami floor begin to creak. Feeling your end coming near, you pulled your lips and tongue away from Rimuru as you looked him straight in the eyes.

"R-Rimuru...I'm gonna...!" You gasped as he nodded while finally being able to wrap his legs around you.

"Do it! Let it all out! I wanna devour everything you've got!" Rimuru said as he was going to devour your seed entirely, opting not to use his skill 'Predator', choosing to absorb it however his body would as he was melding into your futon at this point.

With a few grunts and groans from you, Rimuru screamed in sheer pleasure as he felt your load fire off inside of his ass as your dorsal plates flashed violently and your tail stood straight up. The orgasm was so intense and almost seemed endless as you resorted to very slow, but incredibly powerful thrust to try and empty yourself of everything you had. Rimuru was becoming more of his transparent blue color in his humanoid form as his lower half had turned itself into a slime form, but maintained shape as you could see the incredible amount of cum you pumped inside of him through his slime skin. Your cock was slowly disappearing behind the clouds of cum in Rimuru's body as it finally shot its last spurt and you collapsed onto Rimuru who wore a stupidly pleased smile on his face while his tongue hung outside his lips. After some time had passed and you two finally came out of your drunk stupors enough to have some sense of rationale and know what you two did, neither of you felt bad or awkward about what happened, in fact you two were wrapped in under your blanket and in your futon kissing cutely as Rimuru laid on your chest.

"Did you feel good?" You asked him as he stared at you with a longing glance.

"Yeah. I wasn't expecting my first time to be with you, but I don't regret it." Rimuru said as you two locked lips once again.

"Neither do I." You said between kisses as you wrapped your tail around Rimuru to pull him closer to you.

"But what do we do? We don't know how the others will react if they find out we did this. Should we even be doing this?" Rimuru asked in wonder.

"...It'll be our secret. Even leaders of nations have secrets to hide from their people. It's only natural." You said to him as he blushed while averting eye contact.

"I see. Then...when we're alone and get that feeling..." Rimuru trailed off as he lowered himself to rest his head in the crook of your neck as his arms slithered across your chest and you felt his legs intertwine with yours. "...Can we do it?" He asked cutely as his flaccid small penis brushed against your flaccid, larger cock. 

"Yeah." You answered him as he smiled and the two of you shared a deep tongue kiss once again, as the night came to an end with you two creating a secret relationship that no one would know about.

Meanwhile, In The House Next Door

"Ohhh, my son..." Your Gojira mother, Malenia, was laid out on her futon naked as she had just finished pleasuring herself while listening to you and Rimuru get it on next door. "He should learn that his walls aren't as thick as he thinks they are." She giggled as she ended the night knowing yours and Rimuru's dirty little secret.
