Amaimon x Reader: Under the Kobushi Tree

“Brother, this country is so full of interesting things. Have you ever seen the giant tower in the Kyoto city?”

“Amaimon, I told you that sightseeing was to be kept to a minimum. The infinity key is a privilege that I gave you only for keeping track of Okumura…”

Amaimon flicked the creases out of the map in his hands and looked up at his elder brother cautiously. First day in Assiah and not a single second wasted. 

“Fine, I’ll go look for him,” he replied apathetically. 

Mephisto’s eyes flickered as his brother began to awkwardly fold up the map. Maybe his brother will have as high of an interest in Rin Okumura as he. He watched silently, smirk on his lips, as Amaimon said farewell.

…

The air was warm and jubilant; it wrapped the entire region in tranquility. There was a slight breeze, and the sun did not shine bright enough for it to be uncomfortably hot. Good thing you had today off — it wouldn’t be fair if you had to be stuffed up in Cram School studying on such a lovely day.

You laid sprawled out under the shade of a large kobushi tree. Its petals littered the grass around you, but you pretended it was a blanket of warm snow. Past the lowest hanging branches, all you could see was the greenery of the mountains of Kyoto. You closed your eyes and inhaled deeply. The only sounds you could hear were the soft rustling of the branches above you and the faint utterance of a stream’s running water a half a kilometer away. 

Out here, very few demons lurked around. Every once in a while, you would see a coal tar float past you and carry on its merry way, or a reaper or two would croak and jump around in the damp patches of grass around you. So peaceful…you could stay here, one with the earth forever.

“Nice day, isn’t it?”

Your eyes snapped open as you jumped to your feet. Above you, hanging from one of the branches of the tree, sat a silly-looking…demon..? You eyed him carefully.

“Hm, you have incredible reflexes for a human,” the man responded. “That certainly seems interesting.”

“Who are you?” you prompted, defensive.

He cocked his head to the side and stared at you blankly. You held his gaze, unwavering. After a moment of silence, he flipped over and hopped down off of the branch. Without saying a word, he stepped toward you. Weaponless, you put your arms up to protect yourself.

As he inched closer, however, you quickly noticed his appearance. Although his clothes were torn and rather gaudy, he was quite an attractive demon. Or, rather, a demon in attractive body. 

Your arms remained upright in front of you, but he stood only centimeters away now. As if your defense was of any use at the moment…

From the corner of your eye, you saw him slowly reaching his hand up to your face, but for some reason, you stood frozen. Defend yourself! C’mon! You shut your eyes.

“You are a pretty cute human, aren’t you?” he said, expressionlessly. His sharp, black nails traced your cheekbone and sent a shiver down your spine. He took notice of your reaction.

“Hm. I think you will be entertaining, indeed.” He brushed a piece of your hair from your face, dragging his nail along your skin as he did. “You can put these arms down, human. We’ll only be having a little bit of fun.”

Still startled from the turn of events during your pleasant afternoon, you finally found your voice again. “I-I refuse to do anything without knowing who you are, demon.” You held your stance firm.

He withdrew his hand and stepped back. “Pretty stubborn too, aren’t you? I am Amaimon, King of Earth. I would assume it’s only courteous to ask for your name in exchange for mine.”

Your eyes grew wide. Amaimon…King of Earth…you remembered reading about him in one of your classes. He oversees all earth-related demons and can use them at his disposal…he is quite a formidable demon as well—in a league with Mephisto, you’re sure. And here he stands, in front of you. You never knew he could hold such an attractive body in Assiah and yet now knowing all of this, you still question whether or not “entertaining” him would be beneficial at all to you…

“I’m _____. I’m training to be a…” you trailed off. What in the world would you do? Even if you’re an exorcist in the making, you couldn’t possibly do anything against the King of Earth. 

Choose your battles, _____. This is a battle that you’d not want to fight, but rather have fun with, and you know it. Keep cool, you thought to yourself.

You lowered your arms to your sides. You accidentally let a smile creep up on your lips. “Alright, Amaimon. You wish to be entertained by me, so I will be sure to put on the best show I can.”

He smirked playfully—the first expression you’d seen him make this whole time. “Now that’s what I’m talking about!”

With a snap of his fingers, he stood directly behind you, already grabbing your sides and flipping you around. He’s so fast, you thought. This is going to be quite the challenge. Suddenly, he slammed you up against the tree, knocking a bit of air from you. Oh holy hell, _____, what the fuck did you just get yourself into? Oh my God…

“Whoops, gotta remember you’re a human,” he mumbled to himself, watching some of the white flower petals fall from the branches. “You wouldn’t be very entertaining to me if you were dead!”

After recovering yourself, you found that deep-seeded lust. Better make it count. You ripped his tie from his neck and tore the seams from his vest, leaving only a severely pleated striped button-up left to contend with. You worked quickly, knowing that you and he shared different perceptions of time. 

You felt him still holding a slight sideways smile as you worked. With his hands still around your waist, you felt those nails of his dying to tear apart the fabric that held your body together as well. When you finally revealed the front of his torso, you had no time to even glance at it, for you felt your shirt split in two; in no time at all, it slipped down to the grass. 

His eyes widened as his nails lightly danced over the lace in your thin bra. It took nothing more than a swift thwip of his nail cutting between the cups for it to fall to the ground on top of your shirt. He closed the space between the two of you, pulling his hips right up to yours, and cupped your breasts slowly at first, feeling how they felt under his palms. You bit your lip and exhaled slowly; he watched you carefully and how you responded to each movement he made. 

With the pleasure of his touch on your skin, you tilted your head back and pawed at his partially exposed chest. You rolled your head forward and leaned over to grab his waist and put your lips around his nipple, letting your teeth nibble at him every once in a while. You felt him tense, but with his hips up against yours, the more you worked at this, more erect he became. Heh, look at you. This is a demon king you’re seducing here. 

His grip on you tightened, and his nails dug into your skin. After feeling the skin break, you  winced slightly and moved your mouth up to the small of his neck and your hands down to his large belt buckle. Again, you made your actions as swift and fluid as you could so as to make his time not wasted.

Without a single fumble, the belt buckle came undone and you felt his hands slide down your figure to where your skirt met your hips. You brought your hand up to the nape of his neck and pulled the back of his hair, so that his head would follow. As soon as you got his shorts undone, he had somehow made your skirt instantaneously fall to the ground.

Suddenly, he grabbed the back of your legs and threw your back against the tree. You cried out in pleasure and broke from your previous task. You felt your legs begin to tremble as you noticed yourself beginning to moisten; before you knew it, you felt those sharp nails of his push aside your underwear and find your entrance.

“You are fun to play with,” he said flippantly. Your eyes grew as you watched his stoic face once again turn to a dull smile. 

Unexpectedly, you felt, not his fingers, but his whole length push inside of you. And again. When did he…? 

His hands clasped the bottom of your butt and with each thrust, your back slid up and down the smooth bark of the tree. You let your head fall back in pleasure and let out a soft moan, and brought both of your hands up to the back of his neck. 

You felt the warmth of this demon inside of you, and damn if he didn’t fill you up. As an exorcist, the whole idea of this situation seemed so wrong, but he was so good with those fingers of his, you couldn’t help but let ecstasy take over your rational thoughts. Ngh, why is he so skilled at this…

Whilst he continued to shove himself into you, you dragged your nails down the small of his neck and pulled him to your chest. You wrapped your legs around his coattails and ended up grabbing one of his hands in order to make him pay more attention to your upper half. You brought it up to your breasts and let him play with them at his own pace. He slowed his movements slightly, but persisted all the same.

“_____, you’re making me want to come quicker,” he mumbled into your breasts. “That’s not fair.”

“That’s part of the game, King of Earth,” you panted.

“Heh, I was good to choose you to play with,” he responded. He shifted his hips and sped up his movements once more. You felt the saliva in your mouth accumulate each time he thrust into your back wall—you bit your lip once again and let a barely audible groan escape your throat.

“I guess it’s polite to let you know that I’m about to—“ he began. You felt warm liquid pulse into you, then trickle down your inner thigh. “Whoops.”

You breathlessly let your head fall as he finished. You couldn’t comprehend why, but it felt so good, having him fill you like this. You inhaled sharply as he lifted his head to look up to you. 

His grip on you loosened as he pulled himself from you. Your legs still wrapped around him, he lowered himself to a kneel to set you at the root of the tree. You looked up to meet his gaze and flashed a quick smile, freeing him from your legs. 

“Quite the show indeed,” he said, letting go of you.

With a snap of his fingers, the mess was cleaned up, and both he and you were fully clothed. That’s rather handy. You sat upright and crossed your legs.

“Well then, Amai—”

“Amaimon!”

Both of you turned your heads to the familiar voice approaching you from the south. There he was—Mephisto dressed up in his usual attire, swinging his umbrella around nonchalantly.

“What a disgraceful deed you have done to one of my students with a key that I entrusted you with,” he said icily.

“Ah, Mephisto,” you said, beginning to panic. “How long…wait…but, if you and…”

“She’s very good at the human sex, older brother. I like her,” he said pointing a finger in your direction.

Mephisto put his hand to his forehead and stayed as calm as he could. “Amaimon, return to my office. You had a task assigned to you, and you couldn’t even do that. _____, please return home. I’d like for you to forget this—”

“Wait! Well, no…I thought this was exciting, Sir Pheles,” you said shyly. You glanced over to his younger brother, who eyed you right back.

Shocked, Mephisto held his mouth ajar. Finally, he sighed. “Do not say a word of what happened here today.”

You nodded.
