Word Count: +4,600 new longest fic for me?

When you heard that Diavolo was going on an overnight trip without Barbatos, you knew you had to go to the castle and get as much alone time as you could with your favorite butler. Considering that Diavolo was also being left in Lucifer’s very capable hands during the trip, you figured Barbatos wouldn’t be in the anxious state that typically overcame him when Lord Diavolo wasn’t under his close watch. So, when you turned up unannounced at the castle that morning only for Little D. no. 2 to answer the door, something seemed off. You tried not to worry, though. Barbatos was probably preoccupied with one of his many tasks.

“Well, if it isn’t Number 2, how are you doing today?” You smiled and patted his head.

“MC! I’m so happy to see you! Are you here to visit Mr. Barbatos? Ooh, I wonder if he’ll come out of his room for you. No one has seen him at all this morning, and when I knocked on his door to check for him, I heard this weird noise before he asked me to leave him alone. Can you believe that? Well, I thought maybe he wasn’t feeling good, so I brought him some tea – now, it wasn’t anywhere near as good as the tea he makes, but when I brought it, he told me that it wasn’t necessary. I left it at the door, but guess what? When I checked back, the tea was cold and untouched. I don’t know what to do, and I didn’t want to call anyone yet because that seems like something Mr. Barbatos would get mad at me for, but since you’re already here, maybe you could check on him and make sure he’s okay.” The monologue recounting this morning’s events spilled from Number 2’s mouth quickly and with no room for interruption.

Without much thought, you had followed Number 2 in the direction of Barbatos’s room – some attempt to physically follow along with his story as your brain processed the information. You let the words absorb into your mind, fishing for a relevant question. It was already past 10AM. Barbatos was always up and about by now. “Did he sound sick?”

“Can’t say. If not sick, he definitely sounded strange – like he was talking with his mouth half-full or something.” Number 2 hummed and tilted his head to the side. “Or, you know how when you bite your tongue or burn it on your soup because it smells too good not to eat it right away – even though Mr. Barbatos warned you to be careful and let it cool?”

“Sure.” You shook your head and stared down the hall. Barbatos’s room was just a few doors down.

“Anyway, I think something is wrong, so I’d really appreciate it if you could look out for Mr. Barbatos. If he really is sick, you’ll take care of him, right?”

“I’d be happy to.”

“Great.” Little D. no. 2 stopped in front of Barbatos’s door and turned around to face you. “I’ll leave it to you. I’m sure the rest of us can find a way to keep the castle running while you tend to Mr. Barbatos, so don’t worry about anything else!”

“Thank you, Number 2. You’re so reliable.” You could tell how worried and eager to help he was. Number 2 nodded and left you outside of Barbatos’s door. You stood there silently for a second, listening for any strange noises or coughs, before gently knocking. “Barbatos, it’s me. Can I come in?”

“MC?” Your name was quiet and muffled.

“Barbatos? I’m going to enter, alright?”

“Wait. I –” he started to protest in an unusually slurred speech, but it was too late. You had already opened the door.

Barbatos’s eyes seemed to glow in the dim light of his bedroom. He had backed himself against the nearest wall. His typically gloved hands were bare, revealing sharp, claw-like nails. One of those hands shot up over his mouth. You heard his tail thump against the wall a few times before he grabbed it with his free hand, stilling its aggravated motions.

“What’s wrong?” you asked him cautiously. He looked different – more demonic than usual.

“Solomon,” Barbatos responded with his hand still over his mouth, only exacerbating his strange enunciation. He was frozen in place.

Of course. You sighed and shut your eyes. What did he do this time? You closed the door behind you and took a few steps into the room. Barbatos eyed you with every move – even as you reached into your pocket to pull out your D.D.D.

“I’ll call him, okay?”

You waited for the phone to ring once before you put it on speaker. Solomon picked up in seconds. “MC, my adorable apprentice, what can I do for you?”

“What the fuck did you do to Barbatos?” you asked him aggressively.

“What do you mean?”

“Something’s wrong with him, and he said it’s your fault.” Technically, that was a bit of a jump considering the facts you had at hand, but it was a logical conclusion.

“What’s wrong with him?”

“Let’s see, slightly glowing eyes and the sudden appearance of claws to start. And – if you don’t mind me adding, Barbatos – his tail looks bigger than before.”

“His tail . . .is bigger?”

“Longer. Thicker. Girthier. Do you need more adjectives?”

“Just his tail?”

“For fucks sake. I didn’t strip him down and give him a full body exam.”

Solomon hummed. “Anything else?”

“He sounds weird – like he has a lisp.” You glanced over at Barbatos, whose cheeks had grown pinker since the beginning of the call. He dropped his hand slowly and opened his mouth, revealing sharp teeth and a long, forked tongue that looked like his tail. A shiver shot down your spine, and you let out a shaky breath before adding, “that’s new.”

“What’s new?” Solomon asked, unable to disguise his intrigue.

“Sharp teeth and a forked tongue.”

You heard a breezy laugh on the other end of the line. “So, good news: I figured out what happened. I accidentally swapped the magical tea blend I made for Barbatos with the one I made for Asmodeus. Oops.”

“Oops?” You sighed while Barbatos let out a low, guttural growl.

“Asmo asked me for a tea to enhance some of his more demonic features for a photoshoot. It seems Barbatos got Asmo’s tea, so Asmo – oh, speak of the devil. He’s calling.”

“Add him to our call.” You looked over at Barbatos, wishing you could apologize for Solomon’s behavior silently.

“What gives, Solomon? Your tea was a total flop. I tested it as soon as I got up this morning. I wanted to check out my enhanced demon features before the shoot tomorrow – maybe indulge in them a bit on my own. Nothing has happened. You promised quick results. I’m still my same, gorgeous self, and all your stupid potion did was give me the urge to organize all of my make-up and tidy half of my closet. I was really depending on you to come through for me here.” Asmo complained, clearly annoyed by Solomon’s failure.

“You basically made Adderall tea for Barbatos?” you asked, staring between Barbatos and your phone.

“Barbatos?” Asmo questioned. “Also, hey, MC~! Are you calling to yell at Solomon, too?”

“Pretty much, yeah.” You nodded.

“Can I speak?” Solomon added quickly, coming to his own defense since no one else was going to. “First, Barbatos asked for something to soothe him and enhance productivity so he could make good use of his day without Diavolo. Second, we had a little mix up, Asmo –”

“ – we?” you interrupted.

“Okay, I had a mix up. You have the blend I made for Barbatos. Barbatos took some of yours. MC is with him now.”

“Ooh. Enhanced demon form Barbatos sounds sexy. Does he look sexy, MC?” Asmo cooed.

“Focus, Asmo,” you responded, too embarrassed to admit the truth. Well, the truth other than that Solomon clearly sucked at making magical Adderall.

“Asmo. I have plenty of the magical blend I made for you left over. I’ll bring it by in a bit, alright? Will that resolve everything on your end?” Solomon’s voice sounded sweet, but there was a grave calmness to it.

“Yes.”

“Then hang up and wait for me, please.” Asmo did as Solomon asked, leaving the sorcerer to clean up the rest of his mess. “As for you and Barbatos, MC, I’m afraid there isn’t much I can do to reverse the effects. Depending on how much he drank, it should wear off anywhere within a few minutes to a full day. Until then, I suggest you leave Barbatos alone. All of his demonic senses are heightened – that includes his urges. He may be dangerous to be around until the effects clear up.”

You looked at Barbatos. His glowing eyes were wide and damp, and his gaze hadn’t left you once during the entire call; even when you looked away, you could feel him staring. His knuckles were white from gripping his tail so tightly. He was even trembling slightly. “No. I’m sorry. I can’t do that. He looks miserable like this. I’m not leaving him. It’ll be fine, just trust me.”

“MC.” Solomon wanted to warn you against it again, but there was no use in arguing with you. “Be careful and call me if you need me.”

“Alright, and Solomon? Learn how to label your shit.” You said it sweetly, but he knew you were livid.

“Sorry! Don’t be mad.”

You hung up the phone and returned your attention to Barbatos. He backed away, pressing his shoulders flush against the wall, as you approached him. It was hard to believe that this was a more demonic version of Barbatos. He seemed so timid and scared. Slowly, you reached your hand out to smooth his hair down. His low growl echoed off the walls like there was thunder muffled inside his chest.

Barbatos gulped and opened his mouth to speak, showing you a glimpse of those magic-sharpened teeth and that tongue – now forked and dyed black and aqua. Overcome by a sudden shyness about his new state, Barbatos covered his mouth again to speak. His breath was unsteady, and his words were quiet. “You should go.”

“But you look miserable. Isn’t there something I can do to help?”

Barbatos dropped his hand, and his gaze followed, landing on the floor. “Help? Please don’t tempt me when I’m like this. I’ve been holding back since you walked into that door – since I first caught your scent from down the hall, if I’m honest.”

You inched closer, testing the waters – testing his control before you cupped his cheeks in your hands and searched his face. When you finally caught his gaze, you realized up-close how unusually terrified he was. You’d never seen him like this, and it only made you want to protect him more – to soothe the fear this spell had pulled from him. Barbatos bit his lip, and for a second you worried he might draw blood, but he didn’t.

“Please,” Barbatos begged with a shaky exhale. You rubbed his cheek with your thumb, hoping to ease his mind. “Don’t touch me any further. I’ll only want more. I won’t be able to stop myself.”

Greed. That was his innate sin. You knew that, and it had never been a concern – even when he lost control. There was always a spark of fear – worry on the lighter days – in his eyes when you caused his composure to faulter. It flashed like lightning. Sometimes, you had to wonder if you had seen anything at all or if your eyes – if his eyes – were playing tricks on you.

The love Barbatos offered was a love that said, “I would like to cherish you always. I will treat you sweetly, and if I must be rough, it will be thoughtful and restrained.” He had never pushed your limits – never even toed the line – unless you asked him to. Now, he was warning you that he did not know his own limits. A dark, selfish, possessive need in him threatened to take everything you would offer him and then some. Barbatos was pleading with you to turn him down, to not indulge him. This was your last chance, and you knew it. All his willpower, reduced into one last-ditch effort to dissuade your trust in him – a final, feeble, “please.”

When you brought your lips to his, it was over. Until that potion wore off, he could indulge his greed until he was sick and bursting with sin; until every ounce of it had spilled over into you, you had committed to take it.

Barbatos wasted no time deepening the kiss. His forked tongue slithered into your mouth, wet and oddly cool compared to the heat of his breath. It wasn’t unpleasant; in fact, you felt a slight shame in how erotic you found this strange new sensation. His tongue entwined with yours like it had never done before. Barbatos also found himself aroused by his new abilities – even more so when you moaned for him. Eager to explore further, Barbatos plunged his tongue deeper down your throat until you could barely breathe. You felt seconds – millimeters – away from gagging on him and pressed against his chest, trying to break the kiss.

Barbatos pulled away, allowing your lungs to recover, but the desperation on his face was worse than ever. Panting and ravenous, he spoke in half-growls: “More. I need more.”

His impatience displayed itself in the way he stripped you of your clothes – reckless with buttons and balling the fabric up tightly in his hands. All the restraint he had went towards refraining from tearing your clothes to shreds. He needed access to more of your body, and with every bit of skin he revealed, Barbatos licked, sucked, and bit part of your exposed flesh.

The feeling of his cool tongue gliding up your forearm made you shiver. Barbatos sank his sharp teeth into your shoulder, breaking the skin and sending a tingling pain through your body. He soothed it by running his soft tongue over the bite mark in slow circles before he licked a trail up your neck, paving a path for him to place hickeys along. Time was lost to you between Barbatos sucking your neck and pawing at your naked body. The sensation of his claws gently scraping along your lower back left you arching into him.

When Barbatos was satisfied with his assault on your neck, he dropped to your chest, marking you and teasing your nipples between the prongs of his tongue. For someone who claimed to be unable to control himself, he sure was taking his sweet time building up your pleasure. If he hadn’t dipped between your legs when he did, you might have found yourself reduced to begging for him.

Barbatos took in the sight of how aroused he had gotten you. His breathing was labored, causing his chest and shoulders to heave. He had waited long enough. You felt his tail wrap around your thigh and pull you closer until you were right in front of his face. His warm breath primed your body for that first, slow, tender lick. Followed by another. Then, one more before his tongue was swirling circles around you. He sucked and licked you ravenously, moaning repeatedly into your body. Barbatos’s moaning was peppered with the occasional growl – reminding you, lest the lust caused you to forget, that Barbatos was an untethered beast.

He clawed up your thighs in the same ravenous manner. Claws sank into the flesh of your ass and thighs, scratching you and pulling you back against him whenever you had squirmed too far away for his liking. You couldn’t escape the constant barrage of stimulation and pleasure. Barbatos refused to stop until he pulled an orgasm out of you. Even then, he overstimulated your sensitive skin with a few teasing licks, cleaning up some of the mess he had made of you. Your knees buckled, but Barbatos got to his feet and pulled you close to support you.

You had not even caught your breath nor come down from your high before Barbatos was kissing you again. He slipped his cum-stained tongue back down your throat, ensuring that you tasted yourself. A low growl rumbled deep in Barbatos’s chest that shook you to your core. The storm had not passed. You weren’t even in the eye of it yet.

As Barbatos continued to kiss you, the familiar sensation of his tail wrapping around your thigh caught your attention. This time, instead of pulling you close, he pulled your legs apart. Had he not been holding you tight, you would have stumbled with the sudden jolt. The silky tips of his forked-tendril-like tail teased between your legs in gentle alternating strokes, occasionally lingering to cup you for a few seconds before the pressure slipped away. Barbatos was building you up all over again. You gripped his shoulders, simultaneously trying to ground and support yourself.

Despite the cloud of lust disorienting him, Barbatos recognized the signs of your weakness and dragged you towards his bed. Even as he pulled you across the room, his tail refused to stop teasing you and preparing you for what was to come. Barbatos had no sooner finally stopped kissing you when your back hit his mattress with a soft thud. Staring up at him, you saw a distorted image of the demon you adored. Maybe it was the enhanced demonic features and those glowing green eyes, or maybe it was the look on his face that told you he was not quite the same Barbatos. His hunger for you had never been this strong – perhaps it would never be this primal and ferocious again. Repressing any fear or hesitation, you wanted to revel in his uninhibited lust.

Fortunately, Barbatos’s tail had a natural wetness to it that aided in the insertion. He lacked the clarity and patience to apply lube before the tips of his tail squirmed into your body. Barbatos delighted in the way your face contorted in pleasure – how you bit your lip to hold back a moan. The prongs of his tail felt cool and soft as they stretched you out, applying pressure to the most sensitive places inside of you. You writhed under him, but it wasn’t enough. He needed to touch you more.

Barbatos scratched his claws gently down your ribs and towards your navel. He fucked deeper into you with his tail and applied slight pressure to your pelvis with his palm, stretching his fingers out above your stomach. Those claws loomed threateningly above your skin while his tail pumped in and out of you. You thought his tail had looked bigger than before, but now you could feel just how much thicker he was. However, you only had a few seconds to dwell on the size before the threat of claws came to fruition and dug into your stomach. The outermost layer of skin split for him, and five distinct pink marks appeared on your stomach; he nearly drew blood. You whined at the pain, but the way your back arched and your muscles tightened told Barbatos that you were in more pleasure than pain.

A brief flash of normalcy came when you heard Barbatos chuckle and saw his lips tug into a wicked smile. “Are you cumming again?”

The noises you were making as another wave of intense pleasure overtook you were the only response Barbatos needed. He was kind enough to slow the movements of his tail as you tried to bring yourself down. It wasn’t fair. Barbatos was making you feel incredible. You were supposed to be the one taking care of him, but there you were, stripped and writhing on your back. All the while, Barbatos was still fully clothed – barring the lack of his standard gloves which had already been removed prior to your arrival. You wanted to make him feel good too.

You reached out for his pants, trying to undo them so you could at least touch him, but Barbatos took hold of your hands and stopped you. “Please, let me focus on you for a bit longer. Please?”

There was no sweetness in his begging – only desperation. It was less of a plea and more of a demand. Refusal seemed off the table, even if you chose it, but you couldn’t. You could hardly refuse Barbatos when he said “please” under normal circumstances – and even less so when he stared at you with such wanton desire.

Barbatos entwined his fingers with yours and held your hands while he watched you come apart on his tail. The way you rolled your hips to get him to press the spot that left your mouth agape was so cute. If he had been gifted with more patience and less greed, Barbatos would have relished in the sight of you fucking yourself on his tail and using him – especially in the exhausted, fucked-out state you were in. Did you realize how flushed you were? Could you feel how hot your skin had become? Were you aware that you had scarcely stopped whimpering and moaning for him in the last few minutes?

“You’re taking it so well,” Barbatos cooed. His affectionate gaze held your attention, even as he pulled another intense wave of pleasure from you. Something about the dim glow of his eyes captivated you. “You’re doing such a good job for me, but can you keep it up?”

Barbatos slid his tail half-way out of you as he dropped to his knees at the edge of the bed. He was trying to go back down on you, but with no opportunity to recover, you weren’t sure how much more you could take. You tugged his hair and stopped his lips and tongue from overstimulating you, earning a whine from him.

“Barbatos, I need you to fuck me now,” you demanded. You couldn’t take another round without at least making him cum once.

Barbatos savored that desperation in you – even if it was just a fraction of his own. He nuzzled your inner thigh playfully. “Just one more taste?”

“No.” You pulled his hair again and made him look at you. “I need it now.”

“Very well.” Barbatos pulled his tail out of you completely and got to his feet. For a second, the way he spoke was so calm that you believed the tea must have been wearing off. Those shining green eyes stayed fixed on your body as he removed his clothes, tossing them into a dark corner of the room. Perhaps the storm was showing signs of passing.

When Barbatos dropped his pants, you couldn’t keep your eyes off the bulge in his underwear and the damp stain, but he didn’t stay contained for long. He stripped fully, finally releasing his cock. He was so hard, and he dripped precum onto the floor. Your mouth watered. Well, if Solomon asked again, it wasn’t just Barbatos’s tail that was bigger than usual. However, you had already taken his tail; you could take this, too. You wanted it.

Your eyes glanced back up at Barbatos’s face as he aligned himself, rubbing his dick against your entrance. Those glowing eyes caught yours, stalling your breath. Even in the dim lighting, those eyes now seemed to be the darkest thing in the room. A low, satisfied growl escaped Barbatos – the last warning from a predator closing in on his prey. The storm was not over, you had merely found yourself in the eye of it for one brief, relenting moment.

He rocked his hips into you, relying on precum and the combined fluids from you and his tail to lubricate himself as he slowly pushed every inch he could get into you. You gasped. The sensation was so different from his tail – so much warmer, pulsating and throbbing inside of you. That initial slow thrust was for your benefit, but it was not intended to set his pace. Barbatos quickly picked up speed, transitioning into rapid, shallow thrusts that repeatedly rubbed against your walls. Still, he seemed to be focusing on maximizing your pleasure.

“I need more,” Barbatos warned you, but you were drowning in too much pleasure, moaning and panting beneath him, to register his warning.

Instead, you whimpered at the shock of Barbatos slipping his tail inside of you. The forked ends swirled around Barbatos’s cock as he continued fucking you, stimulating you both at the same time. It felt like thick, cool, squirming ridges around a hot, throbbing core. Not even an advanced toy could do this to you. But it wasn’t enough for him. Barbatos reached down between your legs to stimulate you further – somehow lucid enough to take care not to scratch you. His touch was light and gentle, contrasting his other insatiable actions, and making your head spin. It was all too much for you. You came again, tightening around Barbatos as you did. He kept fucking you through it.

A pleased moan escaped Barbatos, signaling that he was close. His hands slid up your body slowly, and then, without warning, he clawed down your sides and grabbed your hips. A stinging sensation immediately followed. He gripped your hips so firmly that his claws broke the skin as he forced himself so deep into you that it almost ached. Barbatos gave you a few more deep thrusts before he bottomed out and held you in place. He pumped his cum into the deepest parts of you, filling you up.

Barbatos lolled his head back with a sigh and a smirk. His chest heaved. It took you squirming against his pelvis for Barbatos to realize that he was still holding your hips up against him. He slid his cock out of you, released his tail’s grip around himself, and gently laid you back down.

You looked so blissful and exhausted, but Barbatos had just gotten started. Simply looking at your flushed face and heaving chest was making him hard again. He caressed your cheek; some of the blood he had drawn from clawing at your hips smeared onto your skin. Barbatos leaned down and licked up the mess. When your cheek was clean once more, Barbatos whispered into your ear, “I’m so sorry, lovely. I’m not done. Do I have your permission to keep going?”

His words floated around your hazy mind. You smiled at him affectionately with your eyes half-lidded and reached up to stroke his cheek. Exhaustion was overcoming you. “Yes. Take whatever you need until you feel better.”

“Even if you fall asleep?” Barbatos asked with some of the timidness from earlier.

“Even if I pass out. Even if it hurts. Even if I cry. Be as greedy as you have to be with me.” Maybe you were cum-drunk. Or maybe you just wanted to make Barbatos feel better. Either way, you resigned yourself to being used for the next few minutes or hours or days.

“Thank you, my love.” Barbatos kissed your cheek sweetly.

You watched the dim glow of his eyes dreamily, focusing on them until the rest of the room began to disappear. With your body spent, all you could do was whimper as you felt Barbatos enter you again. Even the pleasure began to dull as you let yourself slip further into the haze. His deep growls and panting were the last thing you heard as your mind fell silent.

Your last thought before a sweet dream swept over you was that, without a doubt, Barbatos would be a mix of grateful and apologetic when you woke up again.

In the morning, Barbatos would ensure you were hydrated, well-fed, and tended to. He would be an affectionate, doting butler for you. And then, someone would have a hefty price to pay.

A/N: I did not think this was going to end up so long, but please enjoy. I am worried I got a little too carried away here. . . but this was still the less deranged Barbatos monster kink idea. Anyway, requests are open and will be until the end of Nov. 5th. And I hope this one does something for some of you.
