Chuuya was ruining Dazai's life.

Ever since Chuuya admitted how much he loved dogs, petting a stray vigorously and repeating the praise of it being a 'good boy,' the idea wouldn't get out of his head. 

Every night, his imagination ran wild with thoughts of him being the puppy that Chuuya adored so much. Of him being called 'good boy' and pet on the head.

With that came concerning wet dreams of things that Dazai had never known he was into. And with that came some very raunchy internet searches and an unintended journey of self discovery. It was a quick and easy decision to pursue his curiosity for the real experience.

The things Chuuya claimed that he loved so much about dogs though, were absolutely ridiculous, and he was probably the only person in the Port Mafia, if not all of Yokohama, that adored the filthy creatures so much.

What made it even worse, at least according to Dazai, was that the things he loved about dogs apparently did not apply to anyone else.

"Chuuya, that dog is biting your arm."

"That's just their way of showing affection. It's playful!"

-But when Dazai bit him to show affection, suddenly it was a bad thing.

He'd even made sure to not bite too hard! It was barely a nip, if anything. Perfectly playful and cute.

When those slobbery dogs did it, they got the privilege of Chuuya's baby voice cooing at them with indulgent laughter and pets, but Dazai just got yelled at and smacked on the head. 

It wasn't fair. 

He wanted to be the one being babied by Chuuya.

More than that, Dazai wanted to be his pet.

Being pampered, fed, and adored by Chuuya just like he would for any random stray dog he came across (but with some added benefits) -it sounded like heaven. 

A little puppy play was all he wanted. Nothing extravagant. It wasn't an outrageous request. 

If only any of his efforts had worked at all.

"Chuuya, what do you think of my new look?"

"Is that a fucking dog collar? Take that shit off, you look ridiculous."

"Chuuya, play catch with me."

"What the hell? I'm not an absent father trying to reconnect with his son or a toddler on a playground. Fuck off."

"Chuuya, do you want to lead me around on a leash?"

"No? Why would I want that? That would be so impractical in a fight. I thought you were supposed to be smart?"

"Chuuya, wouldn't it be fun if you chased me in the woods?

"Well yeah that might be... wait, no. You probably rigged a bunch of traps in there! Nice try."

Even his subtle actions did nothing but annoy him, which made no sense because he was just doing exactly what the dogs did! Why was Dazai any different?

"Ew, did you just lick me?! You bit me last week too! Stop trying to eat me!"

"Don't eat out of a bowl on the ground, that's so unsanitary! I'm glad you're eating but what the fuck?"

"Why is there a crate in my living room? Are you gonna frame me for kidnapping or something?

If he could risk wearing dog ears and a tail without Mori making some kind of weird and pervy comment about it, he would. Being anyone's pet besides Chuuya's made him want to vomit. He'd rather eat cement than allow that, even though that would be an awful way to die.

Though he might end up dressing the part anyway regardless of the consequences if this torture continued any longer. There was only so much he could take. 

Still, he absolutely refused to give up.

-

"Odasaku," Dazai moaned, dropping his head onto the bar in defeat, "I don't get it! He loves when the dogs do these things. He should be petting me on the head right now, and not those disgusting, flea-ridden beasts."

His older friend took a long drink of his scotch, mentally preparing himself for the conversation to come.

"Have you tried just telling him how you feel?"

"Absolutely not," Dazai scoffed, looking at Oda like he was the unreasonable one, "and I cannot believe you would suggest such a thing."

The number of finished and empty drink glasses on the bar top steadily increased to an amount the Lupin had never seen before as their conversation continued in the direction of Dazai complaining about Chuuya, Dazai explaining what he wanted Chuuya to do to him, Dazai going into detail of what he thought was so interesting about puppy play and why he wanted to try it with Chuuya. It was the first time ever that he was drinking with Oda and Ango, and they had to be cut off by the bartender that usually let them drink pretty much however they wanted.

Yet even spending hours with the only two people who he would call friends proved fruitless. They had no good advice to give, only the foolish advice to genuinely admit his feelings to his crush. As if that were ever a possibility. He thought they knew him better.

He ended up having to get both of them rides home, not even having had that much to drink himself.

-

Everyone had a breaking point though, and Dazai's unfortunately came much sooner than he expected, though mostly because he didn't expect to have one at all.

It came when Chuuya used the crate and dog bowl he put in Chuuya's living room (for himself!) to house an actual dog. Dazai nearly shot the thing in a jealous rage when he found out.

Luckily for both of them, Chuuya was clueless on how to care for a dog properly.

He'd grown up on the streets with the feral dogs, and so did not realize any of the responsibilities that came with actually owning one. One night he gave the dog the rest of his own dinner and the dog got sick. Another time, he’d let one of his feral dogs meet Elise and it tried to attack her. After that incident, Mori forbade him from owning a dog, and so Chuuya had to settle for only occasionally taking care of the strays plaguing the city.

Still, the disrespect towards all of Dazai's efforts was the last straw.

He finally went to the costume store and bought dog ears and a tail, put on his collar (with an appropriately engraved 'puppy' on the tag), and sat himself along Chuuya's usual walking route. He’d even degraded himself further by sitting in a cardboard box like an abandoned pup.

The plan went horribly. Even begging Chuuya to 'adopt' him failed, and he was shot down.

Dazai was at his limit. 

-

It all came to a head one night when they were lounging around on the redhead's couch watching a movie.

Dazai tried very subtly to rest his head on Chuuya's lap, but was pushed away with a curse before cheek could even touch thigh.

That. Was. It.

"Chuuya," Dazai somberly got up in front of the TV and dropped to his knees, pleading with a deadly serious voice, "Please make me your dog. I am begging you. Dress me up and make me do embarrassing things. Praise me for doing what you say and punish me for disobeying. I want to be your pet. Please. I'm genuinely begging."

The room went silent.

Except for the noise from the TV, which was playing an adequately timed intimate scene.

There were several reactions he accounted for: furious blushing and stuttering, a smirk and immediate abuse of the power he'd just been offered, disgust at Dazai's kinks and crush, laughing and making fun of him for being so pathetic. They were expected. Any of the responses would have been more than fine with him.

Except for the one he got.

Chuuya's eyes narrowed in suspicion, "What kind of new manipulation tactic is this? What are you trying to get from me now?"

Dazai wanted to fall into a river and drown.

The frustration that buzzed through his bones was like swarming bees and unlike anything he'd ever felt before. He was at a loss on how to move forward with this. There were no more plans he could possibly put into place. Nothing he could say. 

The only option left was the nuclear one.

He slumped down until all of his weight leaned onto his hands and knees on the floor, making the rest of his body loose and pliable. His eyelids fell to being half-lidded and sultry, gazing up at Chuuya, stupid Chuuya, who was sitting completely still with a body tensed as if ready for a fight. Even with Dazai on his hands and knees in front of him, Chuuya remained wary.

A whine keened from his throat, a sound he'd only ever made in the privacy of his own room when he was imagining scenes exactly like what this would hopefully turn into.

Ever so slowly and cautiously, making no sudden movements that would startle Chuuya, Dazai crawled across the floor to the front of the couch, holding eye contact the entire time. He only stopped when he was close enough to touch Chuuya's legs.

Their methods of communication were abysmal, but one thing Dazai was positive of was that they talked more through body language than with words. The connection between them thrived on a physical understanding of each other, and so if nothing he said would convince Chuuya that he was being serious, this should. 

He didn't need to ask aloud whether it was alright to continue trying to prove his honesty. Chuuya tilted his head down anyway in a nod, his edge slowly turning into curiosity.

Dazai bent his elbows, lowering his front half to the floor but keeping his back arched. He suppressed a victorious smirk at the fact that Chuuya was wearing sweat shorts since they were supposed to be just relaxing tonight. This would make things much easier.

Starting just above the inside of his ankle, Dazai left a wet kiss on his skin.

He heard a sharp intake of breath and a quiet, "oh," above him, but he didn't look up just yet.

This time he allowed himself a very small smirk before he continued his work, placing soft kisses leading up Chuuya's defined calf. When he finally reached the inner junction of Chuuya's bare knees, he let his eyes slip closed and pressed a harsher kiss into the sensitive skin just before his thigh. He sucked and bit, ignoring everything except the taste of Chuuya's sweat, until there was a newly darkening bruise.

It was only now that he started to get a little nervous about the whole thing. 

This wasn’t something that they did. This was crossing boundaries that they might not have known even existed. 

Not only that but this was something Dazai had only ever fantasized about. 

He knew he’d wanted to try it but he didn’t expect to be this anxious now that he was in front of another person- even if that person was Chuuya. 

Especially since that person was Chuuya.

He wouldn’t be himself if he couldn’t hide his nerves though, and so he steeled himself, nuzzling his head into Chuuya’s knee for both his own comfort and the play, and flickered his eyes open to look up at him.

He didn’t think it was possible to feel more than what he was already feeling, but the look in Chuuya’s eyes as he looked down at Dazai made his stomach flip and face heat up.

The icy blue eyes had darkened considerably, though he still seemed mainly shocked at what was happening. Dazai himself was also a little shocked that he was doing this. Embarrassment and arousal fought for dominance in him, but he couldn’t focus on which one he felt more of, needing another cue from Chuuya that this was okay. That this could continue. That Chuuya would take control so he wouldn’t have to be thinking of any of this at all.

Both of them held their breath as Chuuya slowly lifted a hand, hesitating for only a moment before dropping it on Dazai’s head, running his fingers curiously through the chocolate locks, fingers gently scraping his scalp, petting him.

Dazai melted.

A soft noise escaped him involuntarily, eyes falling half open once again as he leaned into the hand in his hair.

All at once he realized how truly unprepared he was to explore this particular side of himself. Every reaction was a genuine first reaction to things he’d never felt or experienced before. He had no frame of reference to attempt to fake or hide anything. Whatever happened from here on would be raw and unknown.

But the hand still petting him gently pushed any worries about that out of his mind.

“Ooohhhh.”

Chuuya said again, eyes now widened in understanding as he finally, finally got it.

Dazai wanted to say something to tease him, but he was slightly afraid that it would make Chuuya stop petting him, so he just leaned closer, laying his cheek down further up Chuuya’s thighs. A gentle sweep behind one of his ears sent a shiver through him.

“This is insane. You’re actually serious. All that teasing about me being your dog- were you projecting?”

Okay. No.

Dazai may have been a little too into everything going on at the moment but he was not a fan of psychoanalyzing. Especially when it was himself being analyzed. 

He bit the tender flesh of Chuuya’s inner thigh a little too hard to be sexy and the other man yelped, snatching his hand back and expression swiftly switching back to his usual anger, “Hey!”

Dazai twitched an annoyed eyebrow, inexplicably still turned on by the anger.

“You are my dog. Don’t think this changes anything.”

And he was well aware that his actions and words were not really making sense together, but he was not projecting. 

Chuuya was supposed to be his master, not his therapist. Though calling Chuuya ‘master’ in his head made his throat go dry, reminding him of the position they were in right now.

“No, no, no, you don’t get to say that.” Chuuya roughly grabbed Dazai’s chin and pulled him closer to his face, squeezing his cheeks together, “Good dogs don’t talk back.”

Oh.

Dazai’s eyes widened, his body immediately reminding him of just how much he enjoyed this, and how if he pissed Chuuya off more he might leave him like this.

Or punish him.

“What if I’m a bad dog?”

His heart was beating fast with excitement. He couldn’t even really decide if it was punishment or praise that he wanted. He wanted something, but couldn’t pinpoint what it was besides just being Chuuya’s pet and letting him decide what he wanted, or at the very least what he’d get, whether he wanted it or not.

Chuuya hummed in thought for a second before releasing Dazai and pushing him back to his knees. Dazai stumbled a bit, needing to catch himself with his hands in a very unsexy way, but he didn’t care about that because Chuuya stood up and started walking away.

Another involuntary noise left his throat but this was more embarrassing than a turned on noise because it was instead a very distressed one. But he was not distressed at Chuuya leaving him. That would be pathetic.

Even more embarrassing though was Chuuya actually stopping and turning to look down at him, a fond smile on his face that Dazai never thought he’d see aimed towards himself. He spoke before Dazai could.

“Stay.”

With that simple command, he left the room and moved somewhere else in the home. 

Dazai heavily debated not listening to the command but… Chuuya’s smile promised something. A reward perhaps?

He’d already tried not following the rules, so he might as well try following the rules. Dazai was a logician, he liked to see all possibilities and explore all routes in order to pick the best one. He liked planning for every eventuality, so that he was always prepared. The success of every mission depended on him having it taken care of. As comforting as this was, it also made him both the warden and prisoner of his own mind.

But puppies didn’t have to think about any of that. Their decisions were all made for them by their owner, and all they had to do was follow. Also unlike when his battle plans were executed perfectly, Chuuya might praise him for doing as he’s told for once. 

Other than Mori’s creepy and insincere compliments, nobody ever showed Dazai any level of affection. Even Oda and Ango, while dear friends, were not the types to just give out praise and compliments. While Oda occasionally showed Dazai some sort of approval, it was always with the knowledge that he could take care of himself and be just fine all alone.

But what if he didn’t want to take care of himself all alone?

He was pulled out of his thoughts when Chuuya reentered the room with a grin that told him he was more amused than aroused at this whole thing. Dazai squirmed where he still sat on the floor.

“Aw, good boy!” Chuuya leaned down, he leaned down.

It was one of those rare but intoxicating moments where Chuuya was above him, and Dazai beneath. The praise hit him like a refreshing splash of water on his face, drenching him.

Dazai almost wished he really did have a tail, as it would surely be wagging right now. The best he could do was sit up straighter, eyes lit up.

Chuuya brought his hand down to Dazai’s head again, petting him like before, though a little rougher now that he was getting into it too.

“You stayed, puppy,” Chuuya cooed, and Dazai’s eyes fluttered closed as he eagerly leaned into the touch, “That's a very good boy, yes you are!”

When he’d fantasized about this moment, he’d imagined Chuuya speaking a lot more suggestively, treating him more like a sexual partner than like an actual dog. 

There must be something severely wrong with Dazai, because this condescending treatment only made him blush more furiously. He turned his face into Chuuya’s arm in a futile attempt to hide that fact.

A quiet click and pressure around his throat caused his eyes to immediately reopen, snapping up to Chuuya, who was smirking down at him and looking entirely too thrilled about this whole thing. 

He’d worn one enough during the past few weeks to recognize the weight of a dog collar around his neck. It was a comfortable fit, just tight enough that if he took too greedy a breath it would pull taut and make him lightheaded. So he did that very thing in order to test the brief floating feeling. He hummed happily when it did exactly that.

The only thing different this time was that Chuuya also attached a long leash to it, bringing Dazai’s attention to the end he held. 

“Now you’re gonna do everything I say, right?” Chuuya asked, confirming that this wasn’t a dream and Dazai was actually choosing to be his dog for once. 

“Well not everything-”

Dazai was cut off by a tug at the collar, which pulled him off balance and forced him to put his hands back on the floor again. He looked up in slight annoyance, trying desperately not to show how turned on he was.

“You’re gonna do what I say because you want to be good for me,” Chuuya repeated in a tone that left no room for debate. It wasn’t a request anymore, “and I’ll take care of you.”

This, more than anything they’d said or done thus far, sent a near unbearable amount of heat to the bottom of his belly. His entire body went from mildly tingly to scorching.

He was suddenly unable to look into Chuuya’s amused eyes any longer, warring with his desire and his instinctive fear of being vulnerable. 

It wasn’t his choice though.

Chuuya didn’t need to grab his chin this time, simply commanding, “Look at me.”

Reluctantly, he did as told and looked up through his lashes. There was nothing he could do to make his eyes look dead, he was far too gone to put a mask on. Chuuya could probably see every little thing he was feeling.

“That's what does it for you? Really?”

Of course Dazai could only try so hard to tamper down his blush. 

He scrunched his eyebrows, pleading with Chuuya to either stop saying these things or keep going. He wasn’t quite sure which. 

“Don’t let it get to your head,” Dazai complained weakly instead of complying. 

It was very hard to not do what they always did and continue a back and forth.

“Ah ah ah,” Chuuya tsked, pulling on the leash again and causing Dazai to stumble forward, “dogs don't talk back to their owners. Don’t make me put a muzzle on you.”

The image that put in his head almost made him not want to submit just so Chuuya actually would do that. He gulped, his adams-apple pressing against the collar and reminding him of his place. 

Dazai lowered his head in submission, almost fully bowing in front of him. 

He could practically taste Chuuya’s excitement in the air at the display, and that in turn reignited the fire in his stomach and chest. It wasn’t quite enough arousal to get him hard, but it was definitely enough for his heartbeat to speed up.

For the second time that evening, he heard Chuuya’s cautious intake of breath from above him, “... dogs also don’t wear any clothes.”

Dazai tensed up immediately, though not out of fear. 

He slowly lifted his head and Chuuya had an eager look on his face. He was enjoying this much more than Dazai thought he would. 

He’d expected him to abuse the control, not to revel in it.

Regardless of the unexpected request, it still made him shiver in anticipation. Dazai got back up to just his knees, sitting on the backs of his feet and bringing his hands up to unbutton his shirt. 

He briefly worried that Chuuya would also want him to remove his bandages. Knowing his partner though, he would probably not push those particular boundaries. 

“Stop,” Chuuya interrupted his actions, freezing Dazai in place, “puppies can’t do that all by themselves. I’ll do it.”

And similar to his reaction when Chuuya offered to take care of him, this more than anything made Dazai submit. 

His head felt fuzzy as Chuuya dropped down to his level, keeping eye contact between them and moving just as slowly as Dazai did before when he was kissing up Chuuya’s leg. 

All traces of hesitation were completely gone from his movements as he gently grabbed the collar of his shirt and began to unbutton it for him.

The process was unbearably slow, Chuuya was taking his damned time moving down his chest, letting the light material of the shirt flutter against his skin. 

His heart was pounding frantically against his ribs by the time Chuuya finally, finally moved the fabric aside, exposing his bare chest. 

As the material brushed against his nipples, Dazai had to bite his lip to hold back a quiet moan. It would be unbecoming to fall apart so easily just from this. They were barely getting started.

There wasn’t any insecurity about how thin he was, they'd never cared about each other's appearances before and they wouldn’t start now, but the way Chuuya’s eyes were glued to his pale skin had his throat closing up and arms itching to cover himself.

Chuuya silently pulled the sleeves over his shoulders and completely removed the shirt, throwing it to a random corner of the room. He wanted to pout at the rude behavior towards his nice clothes but when Chuuya’s hands trailed down his chest to the zipper of his pants, all he could really do was chew his lip to hell and hope the other man couldn’t see his clenched fists. 

His pants were removed slightly faster than his shirt, if only because there were less buttons to go through, but in order to get out of them he had to fully sit on the floor and let Chuuya pull his legs out in front. 

Dazai leaned back on his hands, grinning wickedly when Chuuya’s eyes widened at his lack of underwear.

“Why?” The redhead groaned like he already knew the answer, which he probably did.

“Haven’t done laundry in a few weeks.”

“You’re so gross.”

Although the scene was tense with arousal, Dazai was glad they could still have their playful banter as always.

It kept him a little more grounded in the present. He did want to stop thinking and let his mind float away, but he didn’t want to completely dissociate out of the moment. 

He just stuck his tongue out in response, hoping it would distract Chuuya from the trembling in his legs. 

It didn’t.

Chuuya ran his ridiculously warm hands up Dazai’s legs, rubbing out the tension. Though with how high he got up the thighs only to stop before reaching his hips, Dazai didn’t feel very relaxed, quivering more severely. 

His dick twitched and to his embarrassment he was already half hard just from some light touching. He couldn’t cover himself though, not with Chuuya still firmly holding his legs in place. This observation only made Chuuya’s smirk sharpen, and his thumbs started rubbing circles into the dip between his legs and hips, sending jolts of warmth throughout his whole body.

“You’re never like this. If I’d known all it took to ruin you was to treat you like a pet, I would’ve done it from the start.”

It was only the fact that they were playing that Dazai let that slide. He wasn’t ruined, and he made damn sure that Chuuya could tell that with the dark glare he sent to him. This was only a scene, as he surely knew by now.

Chuuya was not at all deterred by his glare though, bringing his hand up from Dazai’s thigh to- caress his cheek?!

Dazai shuddered, face on fire and eyes slid shut. 

He couldn’t stand to bare his soul to Chuuya any more. This was supposed to be kinky and sexy, not tender. Everything Chuuya did that didn’t follow the carefully constructed script in his head made his stomach turn, though he wasn’t sure whether the feeling was painful or pleasurable. Maybe both. With the few emotions he did experience, it was often difficult to tell the difference.

“What is it about being a puppy that fucks you up so much? Are you a furry?”

Hmph.

Every time he was starting to get into it, Chuuya pulled something like that. He was so annoying.

“Chuuya, if you ever try to put me in a fursuit,” He paused, giving the other man a dark smile he usually reserved for his torture victims, “I will dismember one of your little strays and leave it’s skin on your bed. That can be your fursuit.”

It was not an idle threat, but Chuuya was not one to care about Dazai’s threats. He was stupid like that.

“You are such a fucking freak.”

Considering Dazai was kneeling naked in front of his partner with a dog collar attached to a leash around his neck, it was an undeniably accurate statement. Dazai simply shrugged.

Chuuya gave his cheek a little slap before taking his hand away. 

“Come on freak.”

He pulled the leash and Dazai began to stand up. However, he didn’t even get halfway before Chuuya pushed him back down, one of those soft gloveless hands on his shoulder.

“The fuck do you think youre doing? Crawl, dogzai.”

As thrilled as he was with the commands, that wasn’t a particularly sexy pet name. Still, he acquiesced, going back on all fours and struggling to keep up with Chuuya’s pace as he crawled into the kitchen. The switch from the carpet to cold kitchen tile was jarring.

“Ah, Chuuya, the floor is cold.”

“Cope.”

He pouted, looking up at the redhead, “I thought you were supposed to take care of me? Chuuya is a terrible owner.”

Chuuya continued to lead him to the cage Dazai bought (finally being used as it was intended to be!), which occupied some space near the kitchen table. His abdomen tightened with arousal at the whole situation despite his wanting to be a brat about it. 

It truthfully felt like he could handle anything Chuuya decided to throw at him. Even being in such a vulnerable position, he felt invincible.

After all, Chuuya loved dogs. 

He would take care of Dazai and make sure he was good. Chuuya was the strongest human being in the world; a god. Dazai couldn’t possibly be more safely protected.

“And you’re a terrible dog. That’s why you’re going in the crate.”

Once close enough, he opened the thing and stood beside it with an expectant look on his face, tugging the leash again. 

“Hmm,” Dazai hummed, tilting his head and pretending to think on it for a moment before smiling, “No, I don’t think I will.”

“The fuck? Did you not just beg me to tell you what to do?” Chuuya glared at him, frustratedly pulling the leash until it was choking Dazai and lifting the upper part of his body. 

The collar restrained his breathing enough that he felt lightheaded but not enough for him to be unable to speak. It was bliss, and even the cold tile against his knees didn’t cool the fire burning up his skin.

“You really are bad at this. Why would I willingly walk into a cage without incentive?” 

It was the same tactic they followed when it came to some missions. They (although mostly it was just Dazai) would occasionally put themselves in danger, walking into a trap in order to get more information or give the enemy a false sense of security. Sacrificing a pawn to capture the queen. 

This method of explaining what to do in mafia terms seemed to work the best with Chuuya, whose simpleton brain was permanently altered to work as a soldier’s would.

Sure enough, Chuuya lifted his chin in understanding, slowly nodding. He tied his end of the leash onto one of the kitchen cabinets, which wasn’t necessary but it amused Dazai anyway.

Leaving him there, Chuuya got out the other present that was intended to be for Dazai the entire time; a dog bowl that matched his own personalized collar, with the label ‘puppy’ printed in cutesy bubble letters. He wasted no time taking some leftovers out of the fridge and popping them in the microwave for just a few seconds.

From the unmistakable smell of crab, Dazai perked up and swayed his hips as if he really did have a wagging tail. He barely did it for a second before freezing though, not having intended to do that at all. Apparently he was getting way more into this than he initially planned to. 

Thankfully, Chuuya was turned around during this embarrassing moment, completely ignorant of the reason Dazai’s shoulders were hunched over in shame. He still had to live with the knowledge of shaking his ass for food, even if no one else did. 

“There,” Chuuya unceremoniously dropped the bowl in front of Dazai, “Here's a treat. Now get in the crate.”

It was less of a treat and more of a dinner but who was Dazai to complain about free food?

“Can I get a spoon or something? I don’t want my widdle pawsies to get dirty.” He held up a limp hand for emphasis.

“Um? No? You can't use your hands, you're a dog. Eat it directly from the bowl.”

His face flushed, looking back down at the appetizing meal and pondering how far he was truly willing to degrade himself for this. 

This didn’t seem nearly as sexy as being undressed or forced to crawl, but for some reason that made it even more erotic. The most degrading thing he’d been told to do by far.

He glared up at Chuuya for making him confront these unwanted kinks he was discovering, but that short slug just looked victoriously down at him like he was on top of the world at this moment. 

The reluctant expression he wore only seemed to confirm what Chuuya already expected; that Dazai would go through with it regardless of the humiliation. 

Wordlessly, he untied the leash from the cabinet and nudged Dazai into the cage with his foot, pushing the bowl inside and closing the door. The little locks clicked in place, though it would be easy to unlatch them if he so desired. This small escape route gave him little comfort as he put his hands behind his back and leaned his face down to the bowl.

And it was crab. It was his favorite. 

With a resigned sigh, he shoved his face into the chopped up seafood and licked it up with as much grace as he could, which was not a lot.

“Good dog!” Chuuya seemed genuinely pleased with him this time, and it only made Dazai bury his face deeper into the bowl to hide his blush.

The possibilities of what Chuuya could do while he was imprisoned rolling through his mind made him look up through his lashes though.

To his utter dismay, instead of doing something like jerking off when Dazai couldn't touch him, or watching him and making comments on how pathetic he was, Chuuya just started taking out leftovers for himself, sitting at his kitchen table and not even acknowledging the man in an animal cage right next to him.

He gaped in disbelief, but the other man didn’t even give him a glance, happily slurping his own noodles without a care in the world.

Surely this was some sort of tactic? Maybe he thought ignoring Dazai would frustrate him, which it did, just not in a particularly hot way.

When the sound of his eating didn’t continue, Chuuya finally spared him a raised eyebrow as if to say ‘what?’

Dazai, who was too baffled to even complain, went back to lapping up his crab.

Why, he lamented as he swallowed the admittedly satisfying food, did he have to have an attraction to the most oblivious man on the planet?

If only he could control his curiosity as much as he could control every other human desire he had. If only Chuuya had never used the phrase ‘good boy’ around him. If only Dazai hadn’t subsequently looked up and gotten off to certain things he’d never had an interest in before. If only. 

But he did, and now he was half hard and naked, licking a bowl clean inside a confined cage in the kitchen of his supposed biggest rival.

What had led him to this moment? How had he gone from attempting suicide and joining the mafia, to this?

The lack of a suitable answer, unfortunately, only fascinated him more. He would continue through with this until the end.

They both finished fairly quickly. Dazai, because he wanted to get to the more fun part of the night. Chuuya, because he was seemingly starving.

Dazai was glad they were so efficient because as arousing as the idea of being locked in a cage was, in reality he was cramping up from being in the same position.

“Chuuuuyyyaaaa,” He whined, “let me ouuutt.”

Chuuya muttered, ignoring him in favor of cleaning his dishes, “The bastard even cries like a dog would…” 

Dazai continued to moan and complain the entire time, so as to stay in character, which Chuuya of course obviously enjoyed so much.

The other man was sneering when he finally opened the crate and pulled him out.

“You are the worst dog I’ve ever had.”

And although it was an insult, the insinuation that Chuuya had him, owned him, made Dazai preen happily. The disgust on his partner's face multiplied tenfold at his reaction to mean words.

“What’s next, chibi? Are you gonna give me a bath? Cuddle me? Pet my hair and-” The things he had to say next were far less innocent, but Chuuya interrupted before he could suggest them.

“Don’t call me a fucking chibi when you’re on your knees right now. Shut up and behave like a well trained dog. We’re going to bed.”

To bed.

His gut tensed up in anticipation, the chill in the air suddenly feeling unbearable on his searing hot skin. With the ideas that flew through his mind at a rapid pace, his mouth started salivating. He was hungry for far more than crab though. He licked his lips and nodded.

Finally, they would be getting to the good stuff.

Not that the rest of this wasn’t fantastic, but Dazai had never felt so cockblocked in his life. He’d gone from hard to soft and back again so many times in the past hour that his hips gently shook in an effort to keep upright. 

He could barely hold himself together enough to crawl after Chuuya to the bedroom, but the promise of what would happen once in there kept him motivated.

Chuuya was holding his leash again and though he wasn’t pulling hard, it was enough to make him incapable of forgetting that he was being led by his master. He caught a glimpse of their reflections on the television screen as they passed by it, and it sent a whole new wave of heat rippling through his body. 

Dazai looked absolutely pathetic, naked and flushed and walking on his hands and knees like a dog. He was a dog. The collar around his neck looked enchanting above the bandages there, another reminder that he belonged to Chuuya. That he was Chuuya’s pet to do with whatever he pleased.

The sight itself was enough to make him hurry up his pace, feeling like every point of contact between his skin and anything solid sent jolts of electricity through him.

When they finally did get to the bedroom, of which he was intimately familiar with having spent much of his time breaking in and rummaging through all of Chuuya’s belongings, Chuuya kneeled down in front of him and removed the leash while still keeping the collar around Dazai’s throat.

Even the slightest brush of Chuuya’s bare hands against his skin had him shivering, looking up at him with round eyes on the edge of begging.

Instead of indulging, Chuuya ran his fingers over his scalp one more time before getting up and moving to his closet to get dressed for bed.

“I don’t have a dog bed but I won’t let a mutt like you get on my nice silk sheets. I can throw a blanket and pillow on the floor and you can sleep on that.”

The redhead did not even look at him as he quickly took off his shirt and pants, switching them out with fancy pajamas. 

Dazai gaped in disbelief.

That… that was it? That couldn’t be it! 

The area between his legs was throbbing with want, having been teased relentlessly and left untouched for over an hour now. 

Didn’t he look so pretty and helpless right now? How could Chuuya possibly resist his allure? Better yet, how could Chuuya have gone through all that without letting them reach the expected conclusion?

After changing, Chuuya turned around and froze in confusion and slight panic when he saw the agony on Dazai’s face.

“What?”

Dazai sputtered, still so thrown off that he couldn’t even think of putting up the act anymore.

“Are you not going to fuck me?”

“Fuck you?!” Chuuya absolutely looked scandalized.

“Yes! What did you think this whole thing was for?!”

“You said to treat you like a dog! I don’t fuck my dogs!”

“But-!” Dazai groaned, putting his face into his hands in despair. 

Unfortunately, his beautiful, stupid, idiotic Chuuya had taken his request literally. As he should’ve known that he would. Truly, this was Dazai’s own fault for having faith that Chuuya would understand what he was really asking for.

“Chuuya,” He dragged his hands down his face, hating that he only felt all the more endeared to his partner, “You got me naked. I gave you a hickey on your thigh. You had to have noticed my-” 

He gestured downward, willing himself not to humiliate himself further but at this point it was pretty much impossible. 

Luckily it seemed to have thrown Chuuya as off balance as he was, the redhead quickly looking away and blushing as red as Dazai had been all night.

“I-” At least he seemed as much at a loss for words as he also was at the moment, “I thought that- I don’t know! You’re weird as fuck, I assumed it was part of that.”

It wouldn’t have hurt him normally but he was feeling particularly exposed, having put his body and desires on full display. Something he had never done before and, if the situation continued to fall apart like this, would never do again.

Still, he hid how insulted he truly was and changed tactics fast enough to throw the other off guard. One of his greatest skills was his adaptability to new situations after all.

“Really? You weren’t into it at all?” Dazai purred, going back to the salacious behavior he’d had earlier when this whole thing began, “You know, there was no real reason to strip me naked. It’s almost like Chuuya wanted to see~”

“I-!” 

He’d successfully stumped him. 

Although Chuuya himself didn’t do anything inherently erotic yet, the looks he’d been giving Dazai all night were nothing short of hungry. He must have been enjoying it more than just bossing Dazai around. 

“Dogs don’t wear clothes!”

“Some do. That poodle we saw during the Tokyo job was wearing a pink sweater.”

Chuuya’s face was completely flushed red, leaving Dazai vindicated as no longer being the only one blushing tonight. 

“If you’d wanted to dress me up in a pretty little costume, you would have. But you wanted me bare.” Dazai swallowed the lump in his throat before continuing, slowly crawling closer to the bed, “Admit it. You like this.”

It was an educated guess at best because despite all the signs, Chuuya had apparently been fine with leaving it at this and going to sleep, but if he knew his partner as well as he thought he did, then Chuuya really was into it. There had to have been a reason for his eyes to look like that when Dazai did something particularly sexy. 

From the look on Chuuya’s face as Dazai lazily climbed onto the silk sheets of the bed separating them, his guesses were correct.

“It wasn’t-” Chuuya had his eyes glued to Dazai’s movements as he rolled over and languidly stretched his body across the surface, “-about that. I just liked telling you what to do.”

Dazai pouted, letting out a dramatic sigh, “You don’t want to command me to make you feel good? I can beg again if that's what you’d like. Oh please master, make me drool all over your throbbing-”

“Ew, I don’t want your slobber on me.”

He protested, yet Dazai could see the subtle signs of intrigue.

Chuuya’s face was still flushed, and the more Dazai spoke the more dilated his pupils became. He also started shifting in place more, body tense and a noticeable outline in his pants that wasn't there before.

“But Chuuuuyyyaa, my mouth is watering just thinking about it! You’re supposed to take care of me, right?” He lifted his eyebrows, pleading with the full force of his doe eyes, “Well I’m still hungry for a treat. Throw me a bone.”

Despite his protesting, Chuuya also slowly inched closer to the edge of the bed. 

He smothered down a victorious smirk, keeping the desperately horny expression on his face because he knew Chuuya was enjoying his begging. He just needed a little more pushing.

Dazai rolled completely onto his back and scooted over so that his head hung off the end of the bed closest to Chuuya. With a keening whine, he dropped his jaw open, curling his tongue to beckon the other man closer.

The air felt much hotter than it had been mere minutes before. The simple act of putting himself on pathetic display like this made his heart race. Had he been a man with any dignity to begin with, this would’ve diminished it.

As Chuuya finally approached him, he hesitantly reached his fingers out to Dazai’s waiting mouth. The second they were in range, Dazai latched onto them like a starving man.

His tongue worked between the digits, his cheeks hollowed to suck them deeper in, giving Chuuya just a hint of what he could have if he would just get on with it already.

“I had no idea you were such a slut.”

Rather than rise to the bait, Dazai just hummed around his calloused fingers. It was true, after all.

“But I’m not fucking you like this.”

The fingers retreated and he groaned loudly at their loss in frustration.

Instead of stopping it all and kicking Dazai out, as he half expected to happen, Chuuya gently grasped Dazai’s bare shoulders and pulled him up into a sitting position, joining him on the bed and turning them so that he had an arm around Dazai in a half-hug.

“You’re my puppy,” He murmured, laying Dazai carefully with his back on the plush pillows, “And I’m going to treat you like that.”

For someone whose personality was defined by sharp edges and rough surfaces, Chuuya was being so unbearably soft. Treating him more like a princess than a puppy.

It both rocked his guts and enraged him.

“I’m not fragile. Don’t act like I can’t take anything you give me.”

“It’s not that,” Chuuya mused, digging his nails into Dazai’s thighs and dragging them up towards his hips, which he then grabbed and forcefully pulled towards himself so that they were in a position similar to when he was taking Dazai’s pants off earlier, proving his point. Any protests he had planned died in his throat.

“You’re my puppy,” he repeated, “I’m going to take care of you, and treat my dog well. You’re going to do exactly what I say, or I’ll train you to.”

Dazai gulped, hard all over again. 

He was in agony. It was bliss.

The mix of a threat and a promise made his head float. Any response he had planned flew from his mind as soon as Chuuya claimed ownership of him. As soon as he promised to take care of him, it was over.

It all felt somewhat out of character for the usually brash Chuuya though, and he wasn’t sure how he felt about it. Part of him wanted to be a brat just so he could see the usual fire that he adored so much.

“How will Chuuya train me?” His voice came out breathless with Chuuya’s hands once again so close to the area that had been aching for touch for hours.

“You’re already planning to disobey? What am I talking about, of course you are.”

Chuuya sighed in a manner that was both exasperated and fond, shaking his head as he, without any warning, grasped onto the base of Dazai’s cock. His resulting gasp was more out of shock than arousal, though that quickly changed as Chuuya got a feel for him.

Exploring, that was the best word for what he was doing. Not jerking him off or teasing him by staying still, just curiously stroking his length and observing Dazai’s reactions. 

He tried to not give anything away, but the little involuntary physical reactions were impossible to suppress. As Chuuya’s thumb swept under the sensitive head, his breath hitched. 

God.

After not being touched for so long, even these little touches had his entire body shuddering in relief. His skin had always been extremely sensitive, but this was a whole other level.

Dazai, despite how slutty he was acting at the moment, was not a particularly sexual person. Every sexual experience he’d ever had was lackluster and not something he’d particularly enjoyed. Usually, he was touched with the intention of his body being used for the other person’s pleasure, or as a transaction. 

Nobody had ever paid this much special attention to his reactions, especially not with the express purpose of making him feel good.

“Chuuuyyaaaa…” He moaned in despair.

It was unbearable.

Chuuya was supposed to be using him for his own pleasure. He was supposed to be making fun of Dazai and bullying him, not looking at him with those eyes and examining his every twitch so attentively. The fact that it was Chuuya only made it worse, because he did trust Chuuya with his body like this, and it was awful. 

His own eyes burned, but he closed them and turned his head away.

Sure, the experience was supposed to expose him sexually, but he wasn’t supposed to be this truly vulnerable.

“Please, just fuck me.”

“I already told you I’m not going to fuck you.” Before his heart could drop, Chuuya continued, “I’m going to claim every inch of you. By the time I’m done with you, there won’t be a single part of your body that I don’t own; that doesn’t belong to me. My puppy.”

His breath left his body in a rush at the words. 

Entirely out of his control, all resistance and fear disappeared from him, mind going completely blank as he relinquished everything to Chuuya. It felt like his brain was full of cotton candy. All of the carefully controlled muscles in his body snapped out of the string holding them together. 

Sinking into the soft sheets beneath him, Dazai closed his eyes and hummed.

“There you go,” Chuuya slowly lathered his leaking precum over his cock, “let me take control.”

Let him take control. It was a choice to relinquish his power over others. 

Dazai sunk deeper, eyes half lidded and hazy. The only thing he could feel was the warm hand tightening it’s grip and the lavish sheets under his skin. It didn’t take long for the sensations to get his hips rocking slowly.

“Chuuya.”

It wasn’t a whine or plea, it was a simple acknowledgement. An appreciation for the person making him feel this way, the person in charge, who was a person unlike himself. He was just a dog. And he liked it that way.

He didn’t even register the hand letting go of him as Chuuya moved to the side bed drawers and pulled out the materials they would need to move forward. He just kept undulating his waist, desperate but unwilling to touch himself any more. 

What had been yearning before now felt like aching. Sexual pleasure was no longer just a want, it was a need as much as breathing was. 

Chuuya returned to him like air to the drowned, and Dazai wanted nothing more than to pull him down and kiss him until neither of them could think, to share the bliss of emptiness, but they had not yet set boundaries. That was probably something they should establish. A tiny problem with that was that Dazai had no idea what his boundaries were, as any that he might have had were broken down by others. But he didn’t want to think about them right now.

Seemingly reading his mind, Chuuya moved his hand to caress Dazai’s waist, the lightness of his touch tickling him out of that train of thought.

“Is anything off limits for you?” The redhead asked in a surprising show of emotional intelligence. 

Dazai shook his head, unable to verbally respond. Chuuya looked doubtful.

“You’re lying,” He observed, resigned but not disappointed, “Fine, but if you freak out I won’t feel sorry for you.”

That was also probably a lie, but the simple idea that it was a lie brought a small, gentle smile to Dazai’s lips. If Chuuya was lying to him, it meant that he would sympathize were such a thing to happen, and that meant something invaluable to him.

“Well I do have some limits, and if you cross them I’m going to kick you out of my apartment butt naked to crawl back to the mafia and explain to Mori why I’m sueing you for sexual harassment.”

Oh. Maybe he did have some things that were off limits.

“Don’t say his name.”

It was meant to sound demanding, but the words that came out of Dazai’s mouth were pathetically vulnerable. It was pleading, but not at all the same kind as he had been using so far. This was fearful.

Though his social awareness was somewhat lacking, Chuuya recognized that this was more than just him not wanting to talk about their boss when they’re about to have sex. It sharpened something in Chuuya’s expression, but he didn’t acknowledge what was said.

“No kissing.” He went on with his own boundaries. At this, Dazai pouted, but he wasn’t about to push a boundary after he had just explicitly made one himself. “You’re going to shower before we do anything else, I don’t even want to know how long it’s been since you’ve taken one and you’ve just been crawling around all over the floor. And nothing of yours is going up my ass. Got it?”

The phrasing almost made Dazai laugh if he wasn’t so insulted, but he was willing to go along with pretty much anything Chuuya wanted at this point. He nodded.

“Oh, and you need to verbally respond when I ask you something.” Chuuya added.

Dazai rolled his eyes, “Yes sir.”

Faster than he could blink, another display of just how much more physically capable Chuuya was than him, a hand clasped around his throat and pulled him up some.

The fingers squeezed the sides, enough for the blood to pool in his head but not enough to actually cut off his oxygen. Dazai’s eyes widened at the sudden show of aggression, but he was far from scared. His dick twitched in anticipation.

“Bad dog. Don’t sass me either.” He let Dazai slump back onto the cushions, head spinning. “Now go clean yourself up while I get ready.”

Dazai had no idea what he needed to get ready, but he could acknowledge that he himself definitely needed to. While it hadn’t been too long since he’d taken a shower (he actually was taking a lot more showers lately on the off chance that his hints to Chuuya eventually paid off, which he was thanking his past self three times over for as this meant he didn’t need to shave anything), he had just eaten dinner and crawled around on the floor. There was a vital need to clean himself out before anything else happened. 

Already knowing where the bathroom was, he made quick work of scrubbing himself down, lamenting that Chuuya had not come in with him to properly wash him like a dog. At the same time though, he was glad Chuuya was in the other room so as not to witness the additional steps that needed to be taken before any anal. 

Coming back to the room, he was surprised and slightly disappointed to see that Chuuya wasn’t there. Maybe he needed to run to the store for condoms or something. 

Dazai sighed. Even when he wasn’t in charge, he had to do everything himself.

He flopped onto the bed, now cleaned and completely nude (except for the dog collar), including the loss of his bandages. He hadn’t wanted Chuuya to take them off, but he had no problem taking them off himself. 

Well, no problem in the loosest sense. It was actually extremely terrifying and uncomfortable, but his longing to feel Chuuya’s bare skin against his own was stronger than his dread of being seen.

So, fully naked and a little too eager to get this going, he shoved two fingers into his mouth and coated them in as much spit as he could. Chuuya wasn’t there to see the display he was putting on, but that was fine because he was imagining something other than his own fingers. This was a little moment just for him.

Once wet enough, he reached below and unceremoniously shoved one of the fingers into his awaiting hole. 

It hadn’t been a while, but he still tensed at the intrusion as he always did. It would be best to relax himself before Chuuya got back, otherwise he might not have as enjoyable an experience as he wanted to.

It was in the midst of him fingering himself like a whore, mouth open and panting, that Chuuya finally walked back into the room with two cups of water in his hands. Knowing that he was probably putting on quite the show, Dazai grinned cockily up at him. But Chuuya, showing an incredible amount of self control, ignored him and quietly placed both glasses down on his bedside table before straightening up and looking down at him impassively. 

He was starting to get worried that he’d overstepped something else when Chuuya at last crawled his own way onto the bed and gently removed Dazai’s fingers from where they were abusing his hole. He let it happen, arms limp under Chuuya’s hold and body a little too pliant.

Once he was laying flat again, Chuuya slapped him in the face. 

It wasn’t hard, as Dazai was well aware that if he truly wanted to Chuuya could knock him out cold with a single slap, just enough to sting and shock him. If he wasn’t so confused as to why it happened, he probably would’ve been turned on by it.

He blinked up at Chuuya, completely lost and kind of upset.

Did he do something wrong?

The unexpected hurt must have shown on his face because Chuuya’s own eyes widened, as if he’d surprised himself with that action, and quickly moved to remediate it by bringing his hand back to Dazai’s cheek and softly caressing him.

“New rule; no touching yourself,” He said in lieu of apology, Chuuya didn’t apologize, “... is slapping okay?”

Dazai nodded without thinking but then Chuuya gave him a look so he took an extra second to think about whether he was actually okay with it or if he was just saying yes to say yes and not disappoint Chuuya.

“... only my face.”

With that consent given, Chuuya nodded, giving his cheek a much lighter slap than before, more of a pat. He had this approving smile on his face that did more for Dazai than if he had verbalized his praise. 

That all handled, Chuuya went to grab the materials he’d taken out earlier, of which Dazai did not utilize when preparing himself, and he grabbed Dazai’s legs to maneuver him into a more accessible position. An accessible position being on his back with his legs pulled up and spread, leaving him splayed open and vulnerable on the fancy egyptian cotton sheets. 

He could control his heartbeat, he could control his facial expressions, but for some reason he could not control the rose coloring spreading from his face to his chest. Chuuya seemed to take great pleasure in this.

The redhead ran a rough hand down the inside of Dazai’s thigh, this time not stopping when he reached the even more sensitive areas. He squeezed the flesh lightly as he went, and it did a lot to help ground Dazai.

The most heavily scarred parts of his body were his thighs, hips, and lower abdomen. Some of the scars there at the moment were older and faded, but there were some that were fresh. As fresh as days ago, still scabbed and healing. Everyone knew what was under his bandages, or at least assumed because very few people ever actually saw them. But to not only be displayed, but almost inspected by someone whose hands weren’t cold and distant like Mori’s... it was short circuiting his brain.

Chuuya’s hands were burning hot, and they did not hesitate or avoid even the fresh scars, though he of course handled them with a bit more care so as not to reopen any. The other people Dazai had slept with, well.

Admittedly, he’d been mostly clothed much of the time, not even taking off his shirt letalone his bandages, but sometimes when he was too fucked up on some drug or another, the fingers exploring his limp body eagerly ripped apart his bandages, only for them to either be disgusted and leave, or be disgusted and cover them back up so they could still make use of him.

Chuuya did neither, nor did he approach them like a doctor would. He simply touched them as if they were just another part of Dazai, like his hair or his limbs, and did not linger but also did not rush. 

The skin was extra sensitive as it was almost never touched by someone other than himself, and he was visibly shaking by the time Chuuya’s confident fingers fluttered over his cock before drifting downwards and teasing his hole, using his thumb to spread one cheek and expose him even further.

“You didn’t even prepare yourself right,” Chuuya tutted like a disappointed teacher, “this is why I’m the only one allowed to touch you.”

Dazai’s mouth parted slightly, though his breath was already too stuttered to even gasp correctly. The lids of his eyes fell slightly as his vision went blurry.

The only one allowed to touch him.

Chuuya would protect his dog from anyone that wanted to touch Dazai. He wouldn’t let anyone else, not even Dazai himself, lay a single hungry finger on him. Realistically he knew this was just for the scene, but some small naive part of his brain that liked to fantasize about a different life was picturing Chuuya like a white knight, tearing off Mori’s arm the next time he tried to sneak his hands up his thigh.

The sound of a cap opening brought him out of his made up fantasy and into the fantasy that he was actually living right now. Maybe some dreams did come true, he thought in ecstasy, as Chuuya rubbed a lube-slicked finger over his fluttering hole. 

Dazai bit his lower lip to stop himself from begging Chuuya to just skip all this and stick it in already. Based on how he had been reacting up to this point, that might just make it so Chuuya wouldn’t stick anything in at all to teach him a lesson about trying to tell his owner what to do.

What a well trained pup he was becoming. 

Luckily he didn’t have to bite his tongue for too much longer. After torturing him for a few more seconds, Chuuya slid his middle finger in, finally digging into his insides.

It felt much better than his own finger. That was the only coherent thought he could formulate, his hips chasing the long finger with each thrust deeper inside. Dazai’s eyes stared blankly ahead, but Chuuya wouldn’t let them, leaning his face in until he was forced to look Chuuya in the eyes. To witness Chuuya’s own arousal because of Dazai.

“More?” He pleaded.

“We go at whatever pace I want to go.” Chuuya reaffirmed his authority, but he added another finger as he said it. 

It didn’t take long for a third to be introduced.

Usually Dazai would only bother with two fingers at most. He just needed to be loose enough that it wasn’t a terrible experience, but his partners wouldn’t like him if he were too loose. Plus, he was impatient, and didn’t want to lose the interest of whoever wanted to sleep with him.

Chuuya didn’t seem to agree, pumping three long digits in and out, scissoring and curling and exploring his guts as much as he explored his dick earlier, if not more. Dazai was leaking he was so hard, the sounds of his wet hole being opened up putting him in an almost trance. 

However, he had a mission.

“You- I wanna taste-” Dazai panted between his teeth, hips struggling as Chuuya’s other hand worked to hold him still. 

Chuuya did not take pity on him, not slowing or speeding up his fingering, but still looked at him as if he was listening attentively. 

Unable to speak in understandable sentences, Dazai tried to weakly grab onto Chuuya’s forearm, pushing it to indicate he wanted the fingers out of him. Chuuya thrusted faster.

Now the only thing Dazai could do while grasping onto Chuuya’s arm was hold on for dear life. As he sped up rapidly, hitting every angle he possibly could until jabbing Dazai’s prostate dead on.

“Ah-!” Dazai jerked, both in pain and pleasure, and feeling a desire for both. At that, Chuuya finally took his fingers out.

The brunette grit his teeth. Unfair. Now his body was shivering to feel more of that, half of his body screaming at him to pull the hand back. But he wanted something else more.

“Let me taste you.” Dazai demanded, voice breathy and strained just from the effort he was putting into holding back the lewd sounds trying to escape him. 

Chuuya raised an amused eyebrow. 

But he couldn’t resist, Dazai knew he couldn’t and he was counting on that. He stuck out his tongue, wet and glistening with saliva, showing just how badly he needed Chuuya in his mouth.

The other man was only human, after all.

He nodded, finally shedding his own clothes and moving up the bed until he was hovering above Dazai’s face, legs straddled on either side of his head. The sight was something to behold. He'd seen most of Chuuya's body before, usually due to his clothes getting messed up in a fight or from Dazai needing to give him emergency treatment. Never his cock though, and certainly never his hard cock. It looked more appetizing than he ever could have imagined.

Dazai wasted no time waiting for him to fuck his face, his head shot forward and immediately started licking him into his throat in the way he knew drove most people crazy with lust. Chuuya was no different, gasping as if he didn’t expect Dazai’s mouth to be so hot, or so skilled.

Dazai hummed, sucking the head a little harder. He was insulted that Chuuya’s expectations were so low. 

Unable to control himself, Chuuya pushed deeper into his throat, and Dazai opened his jaw to accommodate, moaning around him. With Chuuya’s cock still in his mouth, he ran his tongue along the underside, following a vein that he could feel pumping along with Chuuya’s heartbeat. It made him glow with pride.

“Do you like that, puppy? You like the taste of your owner’s cock?” Chuuya teased, thrusting in further, causing Dazai to choke on him. 

Chuuya stopped, as if worried about his gag reflex, but Dazai could not have him holding back now. He disobeyed a little bit and brought his hands up to Chuuya’s ass, pushing him more until he could feel his chin reach the balls. Dazai’s eyes rolled up to look at Chuuya above him, giving a meaningful suck. 

Chuuya’s face was flushed, eyes wide at the sight Dazai must be giving him. His own view was not half bad either. He bobbed his head back before swallowing down to the base again, his throat spasming and bringing the tiniest tears to the corners of his eyes. 

“Oooh, you are such a good boy,” Chuuya moaned, going back to thrusting into Dazai’s mouth on his own. 

One of his hands moved to Dazai’s hair, running his fingers through it and sending shivers down his spine, causing his hips to buck up into the air. He whined around the cock gagging him, high pitched noises just barely escaping him. 

Chuuya’s other hand joined in holding Dazai’s head, and he manually moved Dazai’s skull, using him like a fleshlight. 

That thought sent Dazai’s eyes rolling into the back of his head, tightening his lips around the skin and dragging it with him as Chuuya continued to use him.

“Fuck, good dog, good dog-” 

He continued using him, making Dazai choke on his cock and not giving him a second of rest. Dazai took it all eagerly. 

Drool started to come out the sides of his mouth as they were wrapped around the shaft, wetting his chin and leaving him struggling to try and suck in more. 

Chuuya growled, taking his dick out to slap it against Dazai’s cheek. Dazai’s mouth still hung open just from getting used to being in that position, but he turned his head toward Chuuya’s cock and gave it a sloppy kiss. 

Chuuya rubbed the head along Dazai’s cheek as he started toying with it using his tongue. Precum and spit was spread all over his face. 

“Is my puppy ready for another treat?” The man above him cooed, scooting back down Dazai’s body and letting his ass brush against Dazai’s dick as he did. 

The sensation made Dazai feel insane, crazed. He nodded frantically.

“Please, please, please, please, ple-”

“Please what, sweetheart?”

The new pet name sent a zap through his brain, making him unable to form words or even thoughts for a moment. That was a dirty move.

Chuuya smirked, as if knowing exactly what Dazai was thinking. He ran a calloused hand up Dazai’s waist until he reached his chest and started idly playing with his nipples while he waited for an answer. Also unfair.

Dazai’s eyes slipped closed but Chuuya pinched his nipple to get them back open. Dazai glared at him, but Chuuya only glared back, taking special care to abuse his sensitive chest. It drew a frustrated moan from his throat, and he huffed, not really in a position to keep being bratty. 

“Please-” He'd said he would not fuck him, “... mark me. Claim me. Make me yours.”

Dazai made sure to purr the words out, showing just how much he wanted this. Just how much he needed this.

Chuuya gulped, as if surprised, but only for a second before he growled and shot forward to latch onto Dazai’s neck. Despite the ferocity of his attack, Chuuya’s lips were soft as they found a spot just above his collarbone to kiss. 

Heat flushed Dazai’s face, turning it a deeper red color. 

Kissing was supposed to be off limits! According to Chuuya’s own boundaries! But perhaps kissing was okay as long as it was not on the mouth. 

Truthfully, that was probably a good thing. If they had been able to kiss mouth to mouth, Dazai might not have survived it. He was already lightheaded with how much he was blushing from this much intimacy.

He tilted his neck, inviting Chuuya to mark him more, and the redhead took advantage of that space, leaving dark bruises all along his throat beneath the collar. Chuuya’s nose brushed against the underside of his chin and Dazai felt himself melt. One of Chuuya’s hands went back to Dazai’s ass again, slipping his fingers lazily inside once again.

It was sweet, slow, and agonizingly tender. 

They could’ve stayed there forever, and Dazai would be content. It felt like peace. Though he still felt the itch for Chuuya to be inside him, he didn’t want to move or change anything to make that happen. 

All he could do was stay there and let Chuuya do whatever he wanted. Like a proper show dog.

That was a concept to be explored later, if they did this again. Being put in front of an audience, leash in Chuuya’s hand and Dazai on the floor at his feet. He gulped, squirming underneath Chuuya.

It wasn’t enough.

Dazai was confused and frustrated. 

He wanted to stay like this forever but he also wanted to keep going. He wanted to cum and he wanted this to never end. He wanted Chuuya inside of him and him inside Chuuya. He wanted, he wanted, he wanted-

“God-” Dazai moaned, unable to hold his mouth shut anymore. 

Chuuya’s fingers digging into him and his lips sucking hickies into his skin; it was too much.

“Yes baby?”

Chuuya was god.

“I want you.”

Dazai pleaded.

His master finally pulled back, looking down at the sight beneath him. The quivering legs, heaving chest, painfully hard dick leaking precum onto his abdomen. It must’ve been quite the picture.

And fucking finally, Chuuya stroked lube onto his own cock before lining it up between Dazai’s cheeks.

The tip slipped perfectly down to his hole and pushed past the rim just the tiniest bit, teasing. The slightest stretch of his tightest part had his legs shaking already. Still, Dazai behaved like a good pup and took whatever his master would give him, even though he wanted nothing less than being completely ravaged.

But Chuuya didn’t give it to him. He flipped Dazai over with a strength that he knew he had but when it was used on him it was particularly erotic. All without simply asking him to turn over, but Dazai was perfectly okay with being tossed around a bit. He’d meant it when he said he didn’t want Chuuya to treat him fragile. 

Those same strong hands lifted his hips until he was face down ass up on the bed. Doggy style. Dazai almost let out an unhinged laugh, but he was too horny to. 

Instead, he swayed his hips impatiently as Chuuya grabbed a handful of his ass. Dazai turned his head as much as he could to look behind him, and saw the self satisfied smirk on the redhead’s face. He hated how much he adored it.

Reaching over the side of the bed, Chuuya picked up the end of the leash and wrapped it around his hand, reconnecting it to Dazai's collar. He then pulled, choking Dazai up onto his hands.

“Now bark, doggy.” Chuuya commanded, leash still pulled taught. 

This position was unfair. Dazai couldn’t see anything interesting in front of him but Chuuya got to see the way his hole twitched at his order.

“I’m not barking, Chuuya.” Dazai instinctively denied him, before realizing his mistake. 

They were not equals in this scenario. He was in no position to deny an order.

“Yes you will.”

“No I- ah!”

Just as Dazai was about to double down, Chuuya pushed inside of him, pulling the collar tight as he forced Dazai to rock back onto his cock, spearing him on it.

Dazai moaned whoreishly, only deciding not to be embarrassed because he heard Chuuya groan and curse behind him as well. 

This was surely heaven. 

Chuuya had prepared him so well beforehand that he was easily able to slide right in, filling him up so nicely.

It didn’t hurt, which surprised him so much he almost pinched himself to make sure this was real. But the pleasure was very much real. The collar still choked him and all he could focus on was how full he was. There was nothing in the world that Dazai cared about other than this moment.

“Bark.” 

Chuuya commanded again, pulling back fully before slowly reentering. He rocked his whole length in and out at such an agonizingly slow pace, Dazai felt like he could cry. 

He tried to move his own hips to fuck himself harder on Chuuya’s cock, because he needed more, but Chuuya put a hand on his back and shoved his upper half roughly back down to the bed. Once Dazai’s face was against the sheets, Chuuya held him there. 

With him in place and unable to move, and with this position allowing Chuuya to push in even deeper until his hips were flush with Dazai’s, what was agony before was now pure torture. The short, stunted moans Dazai produced were turning into long drawn out sighs.

“Mmmhmmm,” Dazai groaned, struggling but unable to do anything but take the slow thrusts Chuuya was giving him, “My owner is so cruel.”

“Hmph, fine then.” 

Without warning, he increased his pace, ramming into Dazai with such a force that it rocked him forward even as he was held in place. The hand that wasn’t on his back was gripping the flesh of Dazai’s ass hard enough to leave more marks. To claim him even further.

“Ah-!” Dazai continued letting out stunted ‘ah’s with each thrust as Chuuya slammed into him, just barely grazing his prostate and flooding his stomach with unbearable waves of heat. 

“Bark- fuck you’re so tight. Bark for me.”

It was the ‘for me’ more than anything that made Dazai finally relent, gritting his teeth all the while.

“R-ruff.” Dazai grunted out, entire face crimson. He squeezed his hands into fists as they grasped onto the bedsheets beneath them.

“Louder.”

Dazai scoffed, but the following relentless abuse of his prostate tore the noises out of him regardless. The shyness quickly dissipated as he lost control.

He screamed a series of animalistic howls and grunts and whines and barks. He felt wild, feral, like a bitch in heat as Chuuya fucked him into oblivion. 

The neighbors must’ve been alarmed by the noise, but if they could see Dazai now they would understand. His eyes were wide open and crazed, body trembling with pleasure. The sounds coming out of him were carnal and loud, but not loud enough to cover the sound of skin slapping against skin. 

He felt alive.

Every thrust inside him was accompanied by a pleased groan from Chuuya behind him, and he couldn’t stand not being able to see his face, but maybe that was for the best. He was sure he probably looked like a rabid dog right now anyway. 

It was obscene how wet his hole was, and how easy it was for Chuuya to abuse it. Dazai purposefully clenched around him to try and make it harder for Chuuya to not roughly force his way in and out.

His efforts were rewarded with a hitched breath and drawn out, “Fuuuuck.”

Chuuya leaned over him now, chest pressed against Dazai’s back as he tried to go even deeper, as if he was trying to rip Dazai’s insides apart and seat himself fully in his guts. The thought made a high pitched keen leave Dazai’s throat. He wanted Chuuya to consume him completely.

He was getting close, he could feel it. The pressure was building, and his breaths started to become heavily stuttered. If Chuuya would only let him touch his dick, he would cum in seconds. It throbbed with need.

And then Chuuya pulled out completely, sitting up and off of him.

Dazai nearly burst into frustrated tears. He was shaking, quivering with the need to cum. It had been hours of edging for him, and he quickly decided he was not into it.

(He was. But with his brain so deliriously horny, he couldn't admit that.)

“Why did you stop?!” He hissed frantically.

Chuuya didn’t answer, instead putting his arm under Dazai and flipping him back over so he was facing upwards. Finally, he could see Chuuya, and Chuuya could see him.

Oh wait, this was so much worse.

Dazai’s hands moved to cover his face, but Chuuya pinned them down so he couldn't. The vulnerability bloomed red on his cheeks. There was undoubtedly still a wild expression on his face, he could feel it, but for some reason could not change it. The effort to try made him pant harder.

The look on Chuuya’s face was…

“Wow, look at you…” Chuuya purred, eyes alight with wonder. 

Don’t look at me.

Dazai wanted to say. 

He knew how he must look. It was fine to let go when it was just him and the bedsheets, but now, seeing Chuuya’s face. He looked so unbelievably turned on. It didn’t make sense to Dazai.

Chuuya slipped back into him without a word, watching as if in a trance as Dazai’s lashes fluttered at the intrusion. He couldn’t help himself.

He continued fucking him, but it was different. 

Instead of animalistic abuse, Chuuya was looking at him. He was watching Dazai’s expressions and moving his body in accordance. It was messing with Dazai’s head.

“Stop looking at me like t-that-” Dazai tried to speak but his voice hitched at a particularly targeted thrust.

With the amount of sex he’d had with people, you’d think he would be used to this. But Chuuya was deliberately hitting his prostate, taking his own pleasure in seeing Dazai fall apart. No one else had ever cared about Dazai’s pleasure.

Sex never felt like this. Even it being the new experience of pet play could not explain away how good it felt. 

“Like what?” Chuuya whispered, somehow completely coherent while he was tearing Dazai to shreds.

A direct hit on his prostate and subsequent rubbing against it had Dazai’s eyes rolling into the back of his head. He moaned. 

Chuuya gave him no space to speak coherently, so he had to make his own.

“Li-ike you’re-”

Attracted to me.

“-gonna eat me.”

The redhead leaned in quick to bite the skin on his collarbone and pull it back a bit before letting go.

“Maybe I will.”

No intelligent response could be formed in his head.

I love you.

The thought made him freeze. Chuuya did not dwell on it, completely unaware of it as it was only spoken in Dazai’s head. He was tenderly staring into Dazai’s eyes as he pounded him into oblivion.

It was messing with his head.

The physical ache within him partnered with the metaphysical bliss. It did not compute. His brain simply could not work it out. 

The only things he could think or feel were pleasure and Chuuya.

His master finally wrapped his fingers around his dick and started stroking him in time with his thrusts. The touch burned, and the attention finally given to it made his stomach flip. He could feel the tears that had steadily built up at the corner of his eyes fall down his temples. Still unable to hide his face from Chuuya, Dazai could do nothing but let out another broken moan.

He must look like an absolute mess; jaw hung loosely open and still wet with drool, eyes glistening, hair out of control, face flushed. A real mess.

“Beautiful.” Chuuya whispered, and then looked a little surprised that he said it.

And that was it.

Dazai’s orgasm hit him with such force that he saw white.

He had no idea what kind of noises he made or what he looked like. After being built up for so long, his cum shot so far that some of it landed on his chin and into his open mouth. But he didn’t even notice, too overcome by the pleasure that was so all-consuming. 

It felt like no orgasm he’d ever had before. 

The sex felt like nothing he’d had before. If he were coherent enough to dwell on it, it probably would’ve sent him into a spiral, but he couldn’t think any proper thoughts at all anymore.

Chuuya was still fucking into him.

The orgasm never seemed to end, even after his dick stopped bursting out streaks of white. Every time he thought it was over, Chuuya hit a spot that kept it going. The overstimulation was making him twitch uncontrollably, back arched in a crescent.

When his vision came back, that’s the first thing he noticed; Chuuya staring into his eyes with an unreadable look on his face as he was very clearly also reaching his edge. The man’s breathing was heavy and his thrusts were not as controlled.

The overstimulation of his hole made Dazai uncontrollably squeeze down on Chuuya’s dick, body still tensing and relaxing with aftershocks. 

Chuuya got to see him cum. That wasn’t fair. Dazai wanted to see Chuuya cum.

“Aaaaahhh~” Dazai’s moan was more of a long breath pushed out his throat.

The dryness of his mouth made him swallow, which then made him realize that he had cum in his mouth, which then made him curious. 

He licked his lips to seek out more of his own taste.

The action made Chuuya let out a long moan. He didn’t need to say a word for Dazai to know how close he was.

Dazai deliberately tightened around him then, trying to give a teasing sexy smirk but failing miserably as it came out a more blissfully exhausted smile. A genuine, too tired to be faked smile.

And apparently that was what did it for Chuuya.

His eyebrows scrunched together as he slammed fully into Dazai once more, hips stuttering and body curved over him. Deep inside of himself, Dazai could feel Chuuya’s cock twitching and pulsing, a different kind of heat filling up his insides.

He couldn’t believe that Chuuya called him beautiful when he looked like that. He was ethereal. 

Chuuya continued steadily grinding into him as he rode out his orgasm, hands gripping Dazai’s wrists so tight they might bruise. More proof that he was owned.

For a minute, they stayed like that, both panting hard and looking at each other with expressions that were too open. It felt like a million words were said between them without either of them needing to speak one. Chuuya was still inside Dazai, connecting them together closer than they could ever be. Bare skin pressed against bare skin, their sweat mixing, Chuuya leaving a piece of himself inside Dazai.

Dazai gulped, suddenly having to hold back words he would most certainly regret.

Their situation seemed to lose its magic as both of them reentered the real world. Dazai had to try and save this before he ended up leaving here confused and heartbroken.

“I can’t believe Chuuya made me bark for him.”

Treat it casually. Sex was just another thing between them. It’s as normal as going on missions together. It was not special.

Chuuya’s face scrunched up and he pulled out unceremoniously, eyes unconsciously dropping down to look at his own cum leaking out of Dazai’s ass. Dazai was still weak enough to blush.

The redhead said nothing though, seemingly completely zoned out. 

“... Slug?”

Chuuya again did not respond, instead hooking his thumb to gather the cum as it leaked out, only to push it back into Dazai’s fluttering hole.

“H-hey!” Dazai’s voice cracked and he was immensely embarrassed by that, but still not nearly as embarrassed as he was by what Chuuya just did.

“You’re my dog now.” 

His partner finally spoke, hand lazily drifting over to pick up the discarded end of the leash that lay to the side. With it in hand, he yanked Dazai up into a sitting position, though Dazai made sure to complain annoyingly about being tossed around.

“I can do whatever I want with you.”

He swallowed.

Every time he thought it was over, Chuuya kept going. 

Even though his dick was limp, completely spent, Chuuya continued fingering his sore hole, pushing the cum deeper inside of him. The sensations had Dazai shivering. This wasn’t about the build up to another orgasm, this was purely a show of control.

And it made Dazai crazy with lust.

He didn’t even want another orgasm. All he wanted was this, forever and ever. Any expectations he had of this being casual pet play were thrown out the window.

He was truly, genuinely Chuuya’s dog now. A part of him would be inside of Dazai forever, even after the bruises that littered his body faded away. The cum inside him would disappear one way or another as well, but this experience would not. Dazai didn’t think he could ever have sex again, especially not with anyone else, without remembering this.

He swallowed, throat dry and too ruined to let out anything more than pathetic breathy gasps. 

Chuuya took his fingers out fully before he could risk Dazai getting hard again, instead reaching over to the side table for the water he’d put there earlier. Taking a sip from his own, he gave the other to Dazai.

Dazai stared at him blankly as he took it in hand, unblinking as he brought it to his own lips. 

A large gulp of water reminded him of the collar still around his throat, and the leash that Chuuya still gripped tightly in his hand, seemingly completely unconsciously. 

This was as unfamiliar territory as the puppy play was. There was nothing he knew about what happened after sex. Usually, the person that fucked him would just leave, or awkwardly try to stay around until he kicked them out. He could not kick Chuuya out of his own house, and he really didn’t want to leave.

His whole body was sore in a way he loved, and though he would have no trouble walking, it would not be without an unnoticeable sway. Unnoticeable to anyone but Chuuya, of course.

The redhead also seemed unsure of what to do, rubbing his thumb absentmindedly along the length of the leash and drinking his water in silence. 

Chuuya was looking into space. Dazai was looking at Chuuya.

The quiet made him uncomfortable, and Dazai could not handle a single second more of it. 

“... we should probably get cleaned up.”

Though he wanted to break the silence, the words still came out softly whispered. The fragility of the atmosphere could not afford to be broken by anything so abrasive as himself.

Chuuya nodded, coming back to the present. He looked back down at Dazai, eyes raking up and down his body, lingering on the marks he left and various fluids on Dazai that were now drying in a very unsexy way. Dazai wanted to rip out Chuuya's eyeballs and peel off his own skin. 

“Yes. You can go first.” 

He sounded robotic, and it terrified Dazai.

Did he regret this? Did Dazai accidentally break something irreparable? 

He was too afraid to ask, and gladly took this opportunity to escape into the safety of the bathroom. He locked the door, very glad that Chuuya did not suggest they shower together. He needed this moment to be alone with only himself and the degenerate in the mirror. Though he couldn’t look at that one.

It was an incredibly quick shower he took, only long enough to cleanse himself of the sweat and cum. And to wipe away the tears that for some reason trailed down his cheeks. Must’ve been an aftereffect of a good orgasm.

He kept the shower running as he got out and firmly tightened bandages back around himself, grateful that Chuuya kept them stocked up. Sending his water bill through the roof would be good revenge. 

Revenge for what?

Dazai couldn’t think of what it was for, but surely Chuuya had done something deserving of it. They always did.

As he wrapped the bandages around his neck, his knuckles came into contact with the collar still attached to him, and he froze. 

It was not his... but it was for him.

He… decided to keep it for himself. Chuuya wouldn’t need it again anyway. The very idea of him putting it on someone else’s neck made him want to smash the mirror to pieces and break everything in the room, including himself. No, he would keep it.

Now fully covered however, the thought of going back into that room paralyzed him. He could not face whatever Chuuya had to say when he went back. There was nothing he could possibly say that wouldn’t make Dazai want to stab himself repeatedly. 

He quickly scanned the cupboards in the bathroom until he found a robe, tightening it to his waist in seconds. It didn’t quite fit, but it covered what needed to be covered and his bandages hid the rest. It would be enough for him to get home at least.

So he kept the shower on as he unlocked the window and slipped out, running like water. 

Back at his own storage container shelter, he could break down. He could jack off to the visions of what happened tonight and be dissatisfied with it. He could not do it here.

A few days later, Chuuya got sent on a mission abroad. A couple weeks after that, Oda was shot and died in Dazai’s arms. 

Days, weeks, years; but no amount of time could weed out the seed of himself that Chuuya had planted in Dazai. No distance could stop him from belonging wholly to his master. 

One day, one day, Chuuya would take Dazai’s leash in his hands again.
