A crisp breeze ruffled Kei’s coat on his way home from the convenience store. It skated over his back and chilled him pleasantly even beneath his big, fluffy sweater.

“Whatcha thinking?”

Kei almost tripped. He caught himself just in time before looking like an idiot and tumbling to the ground.

Kei doubted that he’d ever be ready for Yamaguchi.

He glared at him. “What do you mean ‘what am I thinking’?”

Tadashi gave a shit eating grin. “You know. For our Halloween costumes this year. What do you want to go as? Hinata’s party’s less than a week away. We need to figure something out.”

He huffed. “I don’t know. You know I’m not good at this sort of thing. You come up with something.”

Tadashi brought a finger to his chin, making a show of thinking. “How about… a pair of dinosaurs!”

Kei stared blankly. “Tempting, but no. Too much work.”

“Oh! You go as Pikachu and I’ll go as Ash!”

He didn’t bother to dignify that suggestion with a response.

“No, huh? How about I go as a black cat and you go as a barn owl. We can tell everyone that we’re Kuroo and Bokuto!” he laughed at his own joke.

Kei snorted and couldn't hold back a smile. Still, he shook his head. “Absolutely not. Can’t we just make this simple?”

“Simple like how?”

“Like I buy you a collar and leash and you go as my dog. I’ll be your owner and that way I won’t have to dress up at all.”

The comment had the desired effect of making Tadashi choke on his own tongue.

Kei waited patiently for his friend to resurface into the land of the living.

“Haha… yeah… hilarious.”

Kei watched, maybe a little too obviously, as Tadashi fingered his water bottle lid. The outward expression of inner turmoil. Kei was all-too familiar with it by now. Tadashi ran through tons of shirts before he even reached the age of eleven because he couldn’t stop poking holes in them with his fiddling.

Thank God he moved onto water bottles. Much harder to break.

“Hilarious.” Kei repeated. It didn’t sound hilarious.

Tadashi’s fingers went crazy. He flipped the water bottle over and over in his hands.

It was a little bit mesmerizing and more than a little distracting. But, then again, Tadashi was always distracting.

It didn’t occur to Kei that his friend had said anything until Tadashi was poking his shoulder with fervor.

“What.”

“I said, let’s do it.”

***

This had to be fake. It had to be some vivid dream.

Kei fixed his glasses.

He glanced in the mirror.

He fixed them again.

There was a knock on his door and he nearly jumped out of his skin.

“Yeah?”

“Tadashi’s here,” Kei’s mother wasn’t a loud person. But she wasn’t exactly quiet. Or subtle. “Have fun at the party, you two!”

Ugh, butt out. “‘Kay.”

The door opened and shut again in under two seconds as Tadashi squeezed himself inside Kei’s room.

You can take up more space, Tadashi. You know that, right? You basically live here.

Still, he was small. His back was against the door like he might need to bolt at any moment. His lips trembled upwards in an uneasy smile. “Hi, Tsukki.”

Kei’s stomach dropped through the floor.

Oh my God. This is happening. He really did it.

Tadashi’s hand burrowed deep into his pocket before reappearing with an unmistakable red collar. The kind of red that caught the eye and made Kei stare. Unable to look away.

First of all, it was clearly made for a dog.

Complete with a little tag and everything.

Kei may have blacked out for a few seconds. He blinked and Tadashi was closer. So much closer.

“So, I thought about what you suggested…”

He couldn’t even respond, his throat was too busy tightening and his mouth was salivating.

“And this way you don’t even have to do anything! Just like you wanted.”

Kei rolled his eyes, grasping for some sense of control. “I didn’t say that I didn’t want to do anything . I just said this would be easy since I wouldn’t have to dress up.”

“Exactly. You won’t have to do anything. Just like you wanted.” Tadashi stuck his tongue out at him shyly, but with a hint of playfulness.

Kei froze and blinked. Once, twice, three times before he abruptly turned away and cleared his throat. “Yeah, well. You weren’t supposed to just get a collar, you know.”

“Don’t worry! I bought a leash too, just like you said.”

Kei didn’t turn around. He didn’t . He made sure of it. “You can’t be serious.”

A moment later, a bright red leash was unceremoniously shoved in front of his face. He took a deep breath.

“This way everyone will notice it! It’ll be completely obvious what you’re going as, so you won’t have to keep explaining it to people all night. You know. Since I’m not going to be able to talk.”

Kei suddenly wanted to fall through the center of the earth. He took the leash with trembling fingers. It had a nice texture to it. It was heavy; holding it felt right somehow. He wondered what it would be like to clip it to a collar that he’d put around Tadashi’s neck. He shook his head and turned back around.

“What do you mean you’re not going to be able to talk?”

“Don’t be stupid, Tsukki. Dogs don’t talk. The only way this costume is going to work is if it’s as realistic as possible. Otherwise people will just think that we were lazy and cheap. And these are our friends Tsukki. Our friends . We don’t want them to start thinking that, do we?”

“I don’t really care what they think.”

Tadashi pouted. “Come on. Don’t be like that.”

Kei smirked, hoping to poke holes in this insane plan. “Dogs don’t walk on two legs, either. Are you going to be on all fours all night, too?”

Tadashi was silent for a moment, staring at Kei’s feet. “I don’t know, Tsukki. Do you want me to be?”

“W— What? I— That’s not— I didn’t say that!”

Tadashi glanced back up at him, a strange look in his eye.

Is that disappointment?

“We should probably get ready, Tsukki, or we’re going to be late.”

He dragged a palm down his face, glasses pushing up to his forehead. He took a deep breath.  “Yeah. Yeah, you’re probably right.”

“Okay, then.” Tadashi moved to put the collar around his neck.

“Um. Wait.”

Shut up! Shut up! This is way too much for both of you! Maybe at least take him out to dinner first??

Kei strangled the annoying voice inside his head. Instead, he continued, like a fearless maniac. “Let me.”

Tadashi became a sun, his smile blazingly bright. “Okay!”

There must be something wrong with Kei’s heart because it felt like it was going to explode and take the rest of his body with it.

Tadashi looked bigger somehow. Like he’d grown a few inches in the mere minutes he’d been there.

Kei liked it. He couldn’t stop himself from leaning into the nice, bubbly feeling of having Tadashi in the palm of his hand.

Or.

Wait.

He shouldn’t get ahead of himself.

Kei hoped his voice didn’t sound too dorky when he tried a gentle suggestion, “Turn around.”

And oh, yeah. Kei could absolutely get used to the splendid visual shiver that rushed over Tadashi’s body. He had to close his big, brown eyes in order to suffer through it. His little shoulders vibrated.

Kei felt it in the air, the warmth that radiated off of the other boy in delicious waves. He wanted to devour it. To taste the air that was somehow carrying this unbelievable tension.

It was like a thunderstorm burst to life in Kei’s bedroom.

Which was nothing new, when Tadashi was around. But, usually things weren’t this… obvious.

It was a little dizzying, this rush.

“Tsukki?” Tadashi’s voice swam through Kei’s foggy brain, “What’re you waiting for?”

Kei cleared his throat and stepped forward. “Nothing. Sorry.” He lifted a hand to soothe down the hairs at the nape of Tadashi’s neck, a motion that was so much like petting him that he’s stunned he didn’t plan it.

The touch drew another shiver from the smaller boy and Kei realized with some apprehension that he was beginning to get hard.

He cleared his throat again and brought the collar up and fit it around Tadashi’s neck, slipping one end through the buckle and fastening it. He shifted his hand but didn't quite manage to slip two fingers between it and Tadashi’s neck. He sighed and undid the buckle to loosen it. Tadashi whined.

“It was fine, Tsukki!”

“No. It was too tight. I should be able to get two fingers between it and your neck.”

“What? Where did you read that? Were you researching this?”

Kei shifted uncomfortably. “Maybe. Yes. Just… online. All the websites said that you should be able to get two fingers between the collar and the neck for an ideal fit for a dog. And I thought that’s what you wanted to be.”

He whined again. “It’s too loose now, Tsukki.”

Kei’s heart skipped a beat and it was his turn to shiver this time. He ran a hand down Tadashi’s back. “The fit is just right for a dog, Tadashi. If you want it to be tighter, you’ll need to wear it while you’re a person.”

Yamaguchi made a sound that Kei had never heard from him before. A light, breathy, surprised little squeak that went straight to his dick. He closed his eyes and took a breath.

“Now turn around and give me the leash.” 

He was surprised once again by the intensity of the rush he got from Tadashi’s unhesitating obedience as he turned around and handed Kei the leash that he’d been fiddling with this entire time. The color really was quite garish. It drew the eye, demanding attention. Kei brought a finger to Tadashi’s chin and lifted it. He could read the little tag now and his breath caught as he did. TSUKKI was etched in bold black lettering across it. He could feel the color rise on his face and Tadashi’s smirk was magnificent. Kei glanced away from him.

“Shut up, Yamaguchi.” he said in a small voice.

“Not sorry, Tsukki.” He replied with a touch too much glee.

Kei huffed before he moved to slowly clip the leash to the collar. Tadashi’s breath stilled at the soft click. His fingers lingered over where they were connected now. 

Kei stared at Tadashi’s Adam's apple as it bobbed under the thick woven fabric of his collar. Almost immediately, Tadashi’s mouth opened again. Like he wanted to have something pushed between his lips.

Like he wanted Kei to push his—

No, stop it. Too much, too much!

Without consulting his brain, Kei gave a tiny tug to the leash.

Tadashi’s breathing grew fast, audible through his open mouth. It was almost like he was a trapped animal, which wasn’t too far from the truth, Kei reasoned. Except… it didn’t seem like he was having a bad time.

In fact, it seemed like he was having quite a good time, if the glazed look in his eyes was anything to go by.

...Also the hard dick pressed into Kei’s thigh.

Yeah. That might be a good hint.

“Tadashi?”

He didn’t get an answer. At least, not in the form of words. The smaller boy’s nose crinkled and his eyes squished shut. His face went one shade closer to pink.

Once again, Kei didn’t think. It’s worked out so far, hasn’t it? “Puppy?”

That got a response.

It was like that word alone shot lightning through Tadashi’s spine. Air rocketed into Tadashi’s lungs in a gasp that Kei registered loud and clear.

His back straightened up immediately from where he’d been slouching, and his arms went stiff at his sides.

If Kei hadn't been so interested in cataloguing every little thing about his best friend, then he wouldn’t have noticed how Tadashi’s hands curled into soft fists.

He tapped at Tadashi’s knuckles.

“Gonna punch me?” Although he highly doubted that with the way Tadashi seemed to display no desire to stand against him. His body was the perfect picture of pliant happiness.

Tadashi cocked his head to the side, eyebrows drooping up in an adorable non-verbal question.

“Fists.” Kei clarified.

His collared costume-partner’s face creeped further towards pink in the color palette. He mumbled something indecipherable.

Kei poked his cheek and gave another experimental tug on the leash.

Tadashi yipped and fell even closer, and yes that was absolutely his dick pressing into Kei’s leg. Dear lord, this day just gets better and better.

Kei almost choked on his next words, but held firm. “What was that?”

Tadashi’s breath caressed over Kei’s neck and goosebumps broke out pleasantly in their wake. “Paws! They’re paws!”

Okay, so maybe Kei hadn’t seen that coming. Maybe his knees buckled a little bit.

But Tadashi gasped.

So Kei investigated. His knee had pushed directly up against Tadashi’s length. And oh my God, he’s grinding on me. What should I do?

Definitely new territory.

Good territory. Very good territory. Exquisite territory, if you asked Kei.

He pressed his leg forward lightly, experimentally. Tadashi whined and humped more insistently against him. Kei couldn’t repress his smirk. “What exactly do you think you’re doing, puppy? Are you being naughty?”

Tadashi whined again, high and needy and shook his head emphatically.

“Really? We’ve hardly even started and you’re already trying to get off on my leg. On my leg, Tadashi,” He said meaningfully and paused, allowing the implication of the words to sink into Yamaguchi’s fuzzed over mind.

The brunette panted and turned his face away from Kei, humiliation coloring high on his cheeks.

“At this rate, we’re not even going to get out the door. Now, where’s the rest of your costume, puppy? Did you bring anything else, or did you just want me to put you in a collar and on a leash.”

Tadashi backed away reluctantly, moving to palm himself as he did so.

“No. Bad pup.” 

His eyes fluttered shut and his hand moved away from his crotch.

“I… um… I brought a few other things…” he said, hoarsely.

Kei raised an inquisitive eyebrow. “Did you? Why don’t you show me what they are.”

Tadashi glanced away from him and began fiddling with the hem of his shirt.

“What is it?”

“I need to take my clothes off.”

Kei’s breath caught again. He took a moment to breathe carefully, evenly, before he allowed himself to speak. “I suppose you do. Dogs don’t really wear clothes, do they, Tadashi?”

He shook his head slowly. “N—No, Tsukki, they don’t.”

“Well, what are you waiting for?”

“I, uh, need you to slip the leash under my shirt.”

Oh. Of course.

“If I get close enough to do that, are you going to be a good pup, and not try humping my leg again?”

Tadashi’s breath hitched and he glanced away again, but he nodded. “I’ll be good.”

Kei huffed. “Alright.” He stepped forward and deftly slipped the leash underneath Tadashi’s shirt. As soon as he had, Yamaguchi immediately began shrugging it off. Kei gasped.

Yamaguchi’s chest was flushed down past his small, dark brown nipples, a testament to just how intensely this little game of theirs was affecting him.

Kei gave himself permission to allow his eyes to linger on his friend’s upper body as the boy began to work at unbuttoning his jeans; while he had obviously seen Tadashi without his shirt on before, this new, entirely novel context made every additional flash of skin more intense, more profound.

Freckles dusted the top of his shoulders and his body was lithe and well-toned. Kei bit back the desire to touch him; to explore the smoothness of his skin, the temptation to see what responses he could draw from that body; the glint of the tag on his collar reassured him.

He’s mine. I’ll have plenty of opportunities to pet him later.

Kei blinked, coming back to himself as Tadashi shoved his jeans to the floor and stepped out of them, leaving him in a pair of black designer briefs that Kei had never seen on him before and that did very little to contain the boy’s thick erection.

“Are those new?”

“They’re… um… special. They’re part of the costume.”

“Oh? How’s that? Show me, pup.” Kei delighted in the visual shiver that ran through Tadashi’s body at the command; a shiver that Kei mirrored as Tadashi once again unhesitatingly obeyed him.

The brunette turned his slender hips slightly, enough to give Kei a glimpse of the back of his underwear—except that there didn’t seem to be a back. Tadashi’s tight little butt was framed by the briefs, but entirely bare, otherwise.

Kei exhaled a breath that he hadn’t realized he was holding. “Now what’s that for?”

Tadashi smiled sheepishly, crossing his arms and taking away the beautiful view of his chest. “I… uh… The costume? It’s in my bag?”

Kei swallowed thickly. He was dreaming. Surely. This was a dream. Right? “I’m waiting.”

Another shiver crept up the smaller boy’s spine and Kei felt like he was getting the hang of this very weird game.

It occurred to him that it was ridiculous how easy this was. How natural it all felt.

Actually, it was a miracle they hadn’t slipped into this sooner. All the months Kei spent feeling like an idiot for staring a little too long in the locker room. What a waste of time.

Tadashi took a deep breath before crossing over to his backpack and bending over.

Kei might have moved so he could get a better view of Tadashi’s naked ass. But so what if he did? No one could prove it. Kei reached out, months of wanting to touch Tadashi like this boiling over. His fingers skimmed the black band on his puppy’s waist.

Tadashi tensed under his hand and his movements stuttered before hurriedly tearing through his bag again.

Kei skimmed lower, cautiously tracing the outline of where the fabric ended and Tadashi’s bare skin began.

The other boy’s reaction was not something Kei was expecting.

Granted, nothing had gone to plan tonight.

“Hnm,” Tadashi’s legs spread a little under Kei’s prodding fingers. Almost like…

“Tadashi?” Kei’s other hand pet bravely into shaggy brunette locks as he leant over to speak lowly into Tadashi’s ear. “How long have you wanted me to fuck you?”

A sharp whine and Kei almost got a face-full of that hair and a bloody nose. Tadashi shot straight up, nearly knocking them both to the ground. “I found them!! Haha!”

Kei steadied himself, heart beating out of his chest. “Jesus fuck, Yamaguchi! What the hell?”

“Sorry, Tsukki! I— You— I—”

“It’s okay, Tadashi. What did you find?” Kei tried to calm him down, changing the subject to something more manageable. Okay, maybe I went a little too far.

But Tadashi’s big brown eyes revealed that he wasn’t uncomfortable. In fact, his face was redder than ever. “I— I do want you to fuck me.”

Kei’s neck flashed white-hot.

Does it get this hot on the surface of the sun? Because I feel like I’m dying in a supernova.

“Oh.” Kei said eloquently.

“I—I mean! I’ve wanted— That’s what I— But when you said about the Halloween costumes I maybe got a little excited and I— But it seems like you’re into it, too—” In his hysteria, Tadashi brought his findings to where Kei could see and Kei’s mouth watered.

“A tail?”

Tadashi shut up immediately. His dick twitched in his underwear.

Kei gulped when his gaze finally crept up to the base of the tail and the assless underwear began to make sense. “A… Tadashi, that’s pretty… big.”

Tadashi’s bottom lip quivered. “I—”

“Have you been practicing for this?” Kei sneered.

“I— Maybe…”

“Well, you’d better be able to handle it. Puppies need to have tails, right?”

Brown eyes clenched shut as he nodded.

Kei eyed the contents in Tadashi’s hands more clearly. The sleek red plug attached itself proudly to the base of an equally-red fake-dog tail. It looked perky and happy and it was a crime that Tadashi didn’t have it in right now. An accompanying pair of leather things clutched tightly in his other hand. They looked a bit like leather pouches.

Tadashi seemed to be aware of Kei’s confusion because he explained with a stammer, “A— And puppies don’t have hands, right?”

“So let me get this straight,” A hungry pit settled deep in Kei’s stomach. He closed the space between them and gingerly plucked the accessories up. “These go on your hands? Does that mean that you won’t be able to do much besides pawing uselessly at everything? If you want a drink at the party, I’ll have to take care of you. If you want some food, you’ll have to eat from my hand. And if you need to get off… I’ll have to help you with that, too.”

Tadashi wouldn’t meet his eyes. 

Which was all the answer Kei needed. “Let’s get on with it, then.”

A little whine and Tadashi obediently presented his hands.

Kei’s stomach fluttered as he effectively trapped Tadashi’s hands into little paw-shaped fists.

His freckled chest pumped air in and out at a miraculous pace.

“You okay, puppy?”

Tadashi whined and turned around hurriedly. “Tail, Tsukki.”

Kei couldn’t stop the laughter bubbling out of his chest at the feeling of Yamaguchi rubbing his naked ass against Kei’s pants. “Don’t be needy.”

“S—Sorry,” Tadashi panted, pawing at himself through his underwear. It was deliciously useless with the mitts on his hands.

Still, Kei couldn’t pass up the chance to give him hell for it. “What do you think you’re doing?”

Tadashi’s voice was disheveled and gravelly. “Tsukki...?”

Kei wrapped one hand around both of Tadashi’s wrists and pulled them gently away from his dick, which was now creating a little wet spot on his black underwear.

Tadashi whined brokenly. The humiliation of being caught laced thick in his voice.

It flew directly to Kei’s own dick, which was most definitely digging into the other boys’ lower-back.

“I— I— S—orry— I’m—”

Kei shushed him soothingly. “It’s okay, puppy. Just be good for me now. I need to put your tail in.”

“Y-Yeah, okay,” he nodded shakily.

Kei moved to sit down on the edge of his bed, spreading his legs. “Well, what are you waiting for? Come here.” Kei gave the leash a little tug.

Tadashi whined and stepped towards him.

“No.”

Yamaguchi froze.

“Pups have four legs, not two,” he said sternly.

There was that beautiful burst of color again as Tadashi dropped onto his knees and the mitts that bound his hands. 

“Good.” He gave the leash another little tug and had to suppress the noise that tried to bubble up in his throat as he watched Tadashi crawl over to him. The brunette stopped between his legs and looked up at him with his large doe eyes. Kei leaned back onto his hands.

“Sit.”

Tadashi stared at him briefly before slowly easing onto his haunches. 

“Good boy.” He reached out and allowed his fingers to glide gently through Tadashi’s hair. He whined and leaned into the touch shamelessly. “Good boy,” Kei repeated, more softly this time, before pulling his hand away from the soft strands and leaning back on it again. He caught Tadashi’s gaze and flicked his own eyes between the freckled boy’s face and his own crotch.

Tadashi tilted his head and quirked an eyebrow at him.

Kei remained silent and looked at Tadashi meaningfully.

“Wha—”

“ No. ”

Tadashi blinked and shut his mouth. 

“No talking. I don’t want to hear another word from you unless I command you to speak, pup.”

Tadashi whined and Kei didn’t miss the way that the boy’s hips stuttered forward lightly several times in response to this new demand. He smirked and flicked his eyes one more time between Tadashi’s face and his own crotch.

The boy’s head moved forward hesitatingly as Kei practically watched him put things together in his mind. He gently nudged forward, nosing along Kei’s clothed erection. The blonde leaned his head back triumphantly, long fingers carding once again through soft strands as Tadashi pressed his nose against Kei and inhaled deeply. Kei watched with hooded eyes as he began pushing more insistently into him, sniffing urgently and excitedly. He didn’t miss the way that his hips tilted once again in response to the treatment.

“Shhhh… Okay, that’s enough, pup,” he hooked two fingers in Tadashi’s collar and tugged him back lightly, but the brunette only whined and tried to continue scenting him even more insistently. 

Kei responded by giving the collar a single sharp tug. “ No. ”

This seemed to pull Tadashi up short and he looked up at Kei with dazed, needy eyes. 

It surprised Kei how difficult it was to feign stern irritation when his insides were practically singing. He never thought he’d get over just how ridiculously hot he found Tadashi’s pliant obedience. 

More darkly, he was finding that he quite enjoyed telling him ‘no’. It reminded him of the thrill he used to receive as a child when he had a brand new, shiny toy that he refused to share with Tadashi, even when it was so blatantly clear on the boy’s face how desperately he wanted to play with it, too.

Tadashi had always been that way; it wasn’t in his nature to be able to deceive others or conceal his emotions. It was one of the main facts that had drawn bullies to him like flies to honey, the way that he would cry at the drop of a hat whenever the emotion moved him, or be so very obviously joyful whenever he was happy. It was a trait that Kei loved; it was also one that made him very well-suited to being a dog.

“Better. Time to get your tail in you, pup,” he patted the bed. “Up.”

Tadashi practically fell over himself in his eagerness as he clambered onto Kei’s bed. He moved to the center of it and looked back at the blonde. Kei pressed against the nape of his neck. “Down.” Tadashi whined, but did as he was told, leaning forward and down, resting the side of his face on the mitts binding his hands.

Kei ran his fingertips along his spine, thrilling in the shiver this elicited, and Tadashi arched the small of his back forward, just as Kei intended him to. “Good pup.” he muttered lightly, reveling in just how displayed Tadashi was and how displayed he must feel in this position.

He took a deep breath and closed his eyes, trying to bring himself down to a manageable level of excitement before he moved behind his friend and placed a hand on each globe of Tadashi’s ass, using his thumbs to very gently spread them.

His breath caught. This was one of the very few parts of Tadashi that he had never seen, arguably the most private, most intimate part of his entire body. He allowed one of his fingertips to stroke over it lightly, delighted in the way that Tadashi’s own breath hitched at the contact and the way that his hole contracted involuntarily at the touch.

“There you are,” he whispered lightly, but still loud enough for Tadashi to hear. It was pink and hairless and quite pretty and despite the fact that he had been entirely unfamiliar with it up until this point in their relationship, he had every intention of becoming very intimately acquainted with it over the next several weeks.

Tadashi whined into the leather of his paws.

Kei shushed him, still dragging intentionally over the flexing muscle. I wonder what his face looks like. An image of a needy, blissed-out Tadashi made him bend over so he could get a good look.

Again, his eyes were snapped shut and his nose wrinkled in an adorably helpless way. He almost looked like he was in pain except for his eyebrows tilting up in a silent more, more, more! But perhaps Kei’s favorite finding was the wet spot soaking steadily into Kei’s bed sheets from the corner of Tadashi’s lips.

“You’re drooling.” It was more of an observation than a direct attack, but Tadashi whined all the same.

He abruptly shut his mouth and tried to wipe at his lips with his little paws, but Kei wasn’t going to have that.

“No, no.” Kei used the hand not currently swiping over Tadashi’s rim to push the puppy’s lips open again. “I like it.”

Tadashi whimpered around Kei’s fingers, sending a cluster of vibrations all the way through Kei’s body. In his excitement, Tadashi pushed his ass back on Kei’s thumb, nearly breaching himself. Drool coated Kei’s hand when he cried out needily.

“No,” Kei withdrew himself completely, leaving Tadashi with nothing to grind on or lick.

Tadashi wilted.

It was amazing how he didn’t fight back. Just took the punishment. Blood rushed away from Kei’s brain and into his dick again.

A silence settled on the room for just a few moments before faint whimpering made its way to Kei’s ears.

“What?”

Tadashi’s cute little butt bobbed encouragingly.

Kei snickered at him before patting it reassuringly. “Good puppies don’t try to take more than what’s allowed.”

Tadashi cried quietly into the sheets. Kei was almost certain no real tears were falling, but Tadashi was definitely sobbing.

But he wasn’t done. “And good puppies definitely don’t beg unless ordered to.”

Tadashi froze. His entire body spoke a silent apology. It reeked of submission and remorse, even though Tadashi was perfect in every way.

It was addicting. “Now, be good for me and stay still.”

Tadashi tensed. He nodded into the sheets.

Kei smirked, spreading Tadashi’s ass again. “Wider, puppy. I don’t want any resistance when your tail goes in.”

A grateful sob, muffled into the bed. His knees widened shakily, toes digging into the sheets as if to ground himself. Kei was sure his fingers would be clutching at the bed, too, if his hands weren’t restrained within cute little paws.

“There you go,” Kei resisted the urge to push inside right then and there. Instead, he opted for another order. “You’re so open in this position, Tadashi. Can you even squeeze your hole shut like this?”

To his utter delight, Tadashi’s rim fluttered shyly.

“Good boy,” Kei breathed. “Now try to relax while I get the lube.”

Tadashi’s body tensed excitedly before he made an obvious effort to release his clenched muscles.

Ke wanted to watch him struggle like that forever. But, he had a mission.

He stepped away, briefly to dig into the bag that Tadashi had brought with him. As he suspected, he discovered a small bottle of lube inside, as well as a few other things that his pup hadn’t revealed to him; a set of adorable, floppy, chocolate brown dog ears, a pair of knee pads, and what seemed to be a gag in the shape of a white bone.

He furrowed his brow and glanced back at Tadashi, who was watching him, but who turned away immediately upon being caught doing so. 

“ Tsk ,” he walked back to the bed and leaned onto it with his knees. “Tadashi, how long has this been a thing for you?”

The brunette whined and shook his head vigorously. Kei sighed and patted his butt again. “Alright. This is a conversation we’re having later when you’re back to pretending to be a person.”

And that… that got a response. Tadashi’s eyes screwed shut and he groaned, hips stuttering once more. Kei snorted, soothing a hand over his lower back before bringing it around for his thumb to work over his hole again, briefly but intensely. His pup when slack, loose and panting. 

“Good. That’s right, you’re okay.” He popped open the bottle of lube and put a few drops on his fingers, before working it over Yamaguchi’s hole, which twitched at the contact, attempting to contract closed but remaining open due to the width of the stance that Kei had put him in.

He was careful not to breach him. Not yet. He was going to save that for later, when he wasn’t so overwhelmed by things himself, as he was now, with how quickly all of it was moving. A moment later, he was pouring a generous amount of lube onto the plug end of the tail and smoothing over it, before beginning to press it firmly against Tadashi.

The pup’s breath hitched and he mewled at the sensation, beginning to pant rapidly, before, to Kei’s irritation, he suddenly pushed back against the steady pressure and Kei was watching as the plug moved past it’s widest point and Tadashi’s ass pulled it greedily into itself until the flared base rested firmly against his body and the perky red tail danced at the shiver and sigh that raced through him at the sensation of being filled, finally.

Kei was stunned by how erotic he found it, but equally put out that Tadashi had rushed the process. He swatted his butt, pulling a yelp from the boy and making his tail dance even more. 

“Bad pup . I just told you not to try to take more than what’s allowed!”

Tadashi let out a few pathetic whines and shifted his hips, causing his tail to wag more.

“Stop that. You’re not going to distract me. I don’t care how eager or excited you are, when I tell you not to do something, you don’t do it.” He watched once again as Tadashi wilted, as submission and remorse seemed to seep out of his every pore.

It was a response that stroked something deep within Kei, this total submission, this signal of intense desire to get back into his good graces, the clear and sincere indication that Tadashi understood that making Kei even mildly unhappy was a profound failure on his part; it was intoxicating and he soaked in it for a few moments before finally relenting.

“I expect better of you. I expect you to be good, pup, and I know that you can be.”

There was something adorable in the way Tadashi seemed to think he would impress Kei by taking the big plug all at once.

So adorable that Kei was starting to suspect that he might not have it in him to be as strict as he wanted. But he tried to hold firm.

To his delight, Tadashi seemed to begin paying for his eagerness all on his own. His hips stuttered again, but this time he wasn’t trying to hump the air like an animal. No, this time he seemed to try to be running away from the sensation of being full. A slurred whimper.

Kei realized he’d been smiling like some evil scientist. He spread Tadashi’s ass again to get a good look.

Tadashi sighed in relief as the toy shifted, but he quickly started whining again when Kei pulled away. His hips went to work again and Kei had to actually stop himself from laughing out loud.

That would be mean.

But then again, it seemed like Tadashi wouldn’t mind the treatment.

“Did puppy get too eager for his own good?”

Tadashi shivered, tail bobbing in the air as his hips kept shifting around helplessly.

“Is it a little bigger than you remembered?” Kei teased, landing a small punishment flick on one plump inner thigh. The way his flesh bounced and his ass clenched down was just so visually pleasing. His sharp little cry absolutely knocked the air out of Kei’s lungs. “Ah-ah, stay relaxed, pup. Clenching down is just going to make it feel bigger.”

Tadashi’s hips slowed obediently, excitable little tail lowering just a touch as he tried to loosen up.

Kei landed another flick further up his thigh, almost where his ass began.

Tadashi whine-sobbed into the sheets.

“Are you crying?” Kei didn’t intend to get so worked-up, himself. But just the idea of Tadashi spilling over in ecstasy or pain (or both, if he was honest) all because of Kei was… just a tad overwhelming.

Tadashi buried his face into his paws, shaking his head fervently.

“Shame,” Kei sighed in mock-disappointment. “We’ll just have to fix that. Won’t we?”

The red tail bobbed slightly from side to side. Wagging. He’s already communicating like a dog. Oh God, he’s perfect.

“Good boy. Wagging your tail for me, huh?” Kei had to admire the adaptability and grit beneath this veneer of blind obedience.

It was more than wanting to be told what to do. Tadashi wouldn’t follow just anyone. Kei had watched him try to stand up for himself multiple times over the years (granted, that had only started very recently). The boy usually quietly went along with hardships. Suffered through them nobly.

But to see Tadashi this enthusiastically pliant was truly a once-in-a-lifetime chance. Was he usually obedient? Sure. But to be this pushy and needy? Now this was something new, exciting.

Tadashi really wanted this.

Kei felt honored. He soothed a hand over the sparsely-freckled ass displayed for him. “Is it still feeling a little too big, puppy?”

Tadashi whined desperately into his paws.

“Bet you want me to gently work you open. Gently ease it out and then back in over and over so that your little hole can get used to being so full for me.” Kei knew he was being mean. But there was a bigger part of him that wanted to see Tadashi huff and pout. “I bet it aches. Doesn’t it, Tadashi?”

A choked sob. More wagging.

Kei stroked his fingers lightly over Tadashi’s ass, giving a small pinch and watching with pure glee as Tadashi clenched down helplessly. “I guess my little puppy should have thought of that before he acted out.”

He patted his butt one more time before moving off of the bed and coming to stand at the head of it. He dropped to his haunches so that he was at eye level where Tadashi’s own face was pressed into the mattress. The brunette whined and pouted at him. Kei snorted and shook his head, before bringing the set of knee pads up into his line of sight. 

“We’re going to put these on now. You’re going to have to lift your legs so that I can. I imagine that you’re going to feel that, now.”

Tadashi glared at him and let out a soft growl.

“Stop it. This is what you get for not giving me the time to prep that tight little hole of yours properly.” At this, Tadashi huffed and hid his face. “That’s better. I expect you to stay on all fours for the rest of the night and I don’t want you bruising your knees in the process.”

He moved back down on the bed and tapped the inside of one of Tadashi’s freckled thighs, which were already spread sinfully wide. The boy whined, but started lifting it slowly. Kei watched as his breathing picked up and his hips stuttered once again.

“That’s a good boy. Now hold it there. I need to figure out how to put it on.” Kei paused, making a show of examining the knee pad and taking his sweet time to do it.

Tadashi was trembling in less than half a minute, thrusting lightly in what Kei was sure was an attempt to adjust the plug, which had clearly shifted with his raised leg. Soon, he was panting, breaths and whines coming fast and light, as he struggled to keep his leg in the air.

Kei finally relented and strapped the pad securely over his knee. As soon as it was on, Tadashi dropped his leg with a sigh and immediately began shifting his hips around again, trying to move the plug into a comfortable position. Kei waited a beat before tapping on his other leg. Tadashi whined and shook his head. Kei sighed before pinching the spot he had just tapped. Tadashi yelped and immediately complied, raising his leg as instructed.

This time, Kei didn’t even bother with the pretence of examining the knee pad, instead simply watching while Tadashi struggled with his own body. 

Kei knew it was mean. He also knew Tadashi liked it. Well, at this point he was pretty sure.

The freckled ass presented so beautifully was shaking with effort.

“Good,” Kei soothed, meaning it with all of his heart. “Hold it.”

A series of wordless begging erupted from the head of the bed. The raised leg wobbled in uncertainty and weakness.

Kei placed his pointer finger thoughtfully on the tip of Tadashi’s tail and pressed down, shifting the plug deeper. “Hold it, puppy. You can do it.”

Tadashi hiccupped into the bed.

Kei’s desire was split halfway down the middle. Caught somewhere between: Please be crying, and Already? Aren’t you going to save the tears for when I’m REALLY teasing you?

The freckled leg wavered.

“Hold it, Tadashi.” Kei stroked his fingertip down the tail to the base. He gave an appreciative little rub to his puppy’s stretched rim before trailing down his raised thigh.

Tadashi’s thigh spasmed under his finger.

“Good boy,” Kei cooed. When he reached Tadashi’s knee, Kei decided that was good enough and strapped the second kneepad into place with great care. “You can relax.”

The immediate response from the body beneath him was a rush of power. It went directly to Kei’s head, making him dizzy. Not only did Tadashi’s leg plop back down, his back sagged gratefully and his breathing puffed loudly against the sheets.

But the most interesting thing was how the wet spot on Tadashi’s underwear seemed to be dripping onto Kei’s sheets.

Kei shifted off of the bed, once again coming to kneel in Tadashi’s line of sight. The boy’s eyes were damp, but no real tears had fallen. Good. You’re so pretty like this, Tadashi, but I want you to make me earn your tears. He leaned into his pup, nuzzling his neck softly.

“You did so good for me, Pup,” he whispered. Yamaguchi shivered and Kei smirked against his warm skin; this, clearly, was another weak point of Tadashi’s. “Such a good puppy, trying so hard for me, hm?”

Tadashi whined and Kei could feel the bed shifting slightly underneath him, no doubt a result of how enthusiastically the brunette was wagging his tail. He inhaled deeply. Tadashi smelled very good; warm and clean with just a hint of his body wash and shampoo.

“You smell good too, pup. Did you know that? Did you try to make yourself pretty just for me? I’m so proud of you. Now let’s put your ears on. How does that sound?” There was that shiver again, and a whine this time.

Kei huffed against the soft flesh of Tadashi’s neck before finally pulling away. He picked up the floppy brown ears and slipped them deftly onto Tadashi’s head before standing up.

He stood, looking at the nearly naked puppy. Tadashi was transformed like this, not only in appearance, but also behavior. Kei didn’t want to admit it to himself, but he was very clearly thinking of his best friend as a pet; as something he owned. He couldn’t quite pinpoint when that shift had occurred, but he couldn’t deny that it had. 

He gave the leash a light tug. “Roll over, pup.”

Tadashi lifted his head and looked at him in confusion.

“Roll over. You’re dripping on my bed and I want to see you.”

Tadashi whined and wiggled his cute little ass, not wagging his tail so much as drawing attention to it.

“That’s okay. You can handle being uncomfortable for me for a little while. You want to be a good puppy, don’t you?” Tadashi gave an adorable little whine before easing himself down so that his freckled stomach was flush against the bed, then he wagged again, before rolling over, exposing his belly and giving Kei a good look at his thick bulge and the large, glistening damp spot on his briefs. He panted and blinked up at him cutely.

Kei’s heart squeezed at the display and he tried not to cuddle his newfound puppy into the bed right there and then.

Later. You’ll have time for that later! Stay focused, Kei.

Instead, his eyes caught on Tadashi’s open mouth.

A pink tongue poked out slightly while he panted. Freckled chest raised and lowered shallowly. Brown nipples erect. And that wasn’t the only thing…

Kei’s eyes grazed back down Tadashi’s lithe body, finally allowing himself to land on the wet spot between his bent legs and really look . He had a hunch that his adorable little puppy wouldn’t be able to stay quiet if he dealt with the hard cock pushing desperately at that black fabric. “Tadashi, listen to me.”

Brown eyes tried to focus through the puppy-fog that had taken over his brain.

“Do you think you can stay quiet if I make you cum?” He made an effort to smooth his voice over, but still injected a bit of urgency. I’m expecting an answer.

Tadashi cowered guiltily, avoiding eye-contact. His paws batted shyly at his ears, straightening them, while his knees bent up towards his chest so that the plug could tilt and stay relatively snug inside of him.

But Kei leaned down, swiveling the tail gently so that he wouldn’t be in pain. He couldn’t bring himself to back away again, now that he had this up-close view of Tadashi’s flushed face and big eyes.

Tadashi sighed out gratefully, eyes tracing Kei’s face. He swallowed thickly.

“Speak, puppy.”

Tadashi remained silent at first, blinking steadily. Then he spoke up, “I-- I don’t think so.”

Kei twisted the tail a little more, just to see Tadashi wince, then start panting again. “Don’t think what?”

Tadashi’s back arched and he hiccupped when the plug brushed against something inside him. “Ah-- I-- I’ll be loud, Tsukki! I’m sorry, but I can’t h-- help it! Ngh! Ah!”

Kei shushed him, scratching playfully into the hair just behind one of Tadashi’s new fake ears. “It’s okay, puppy. You’re perfect. You don’t have to talk anymore. Just lay back. I’m gonna give you a treat.”

Tadashi’s chest rose and fell in relieved puffs. His tongue lolled out and his knees fell open more. He nodded and a little whine gurgled out of his throat.

Kei palmed the bone-shaped gag and smiled to himself.

Still maintaining his smile, he brought it into Tadashi’s line of sight. “Open up, puppy.”

Tadashi yipped and tilted his head back, opening his mouth and panting. Kei didn’t miss the way that his hips started moving back and forth on the bed. Still trying to wag, even in this position. He really is adorable like this.

He gingerly placed the bone gag between his puppy’s lips, and reached behind his head to secure it in place, carefully watching Yamaguchi’s face as he did so. He smiled more widely as the boy’s nostrils flared, his eyes grew a little more dim, and he made a small, satisfied noise in the back of his throat as Kei essentially removed his capacity to be verbal; with his paws on, there was no way that he would be able to remove the gag without Kei’s help.

Tsukishima huffed, scritching behind one of Tadashi’s ears again, while his pup whined happily, eyes falling shut and one of his legs kicking rapidly and playfully into the empty air.

Kei allowed the hand that had been scratching him to glide slowly down his pup’s nearly nude body, stopping to tease and roll one of the pert nipples between two fingers and marveling at the full-body shiver that this elicited from Yamaguchi.

“These are sensitive, huh, pup.” He moved his free hand to begin working Tadashi’s other nipple, drawing a whine from him and causing the boy’s hips to stutter once more, fucking up uselessly into the open air. Kei snickered “You keep doing that. It’s cute, considering that you’re not going to be fucking anything for the foreseeable future. Your body seems to really want to, though.”

Tadashi whined long and desperate at this. Kei shushed him, and continued sliding his hands down his lithe body, appreciating the smoothness of his skin, and the way that his muscles, warm and hard as they were, responded to him by squirming pleasantly under his touch.

Once he finally reached Tadashi’s briefs, he traced a single finger down the clothed length of his hard cock before hooking them under his waistband and slowly, slowly, pulling it down, wanting Tadashi to be acutely aware of every new inch being exposed to Kei’s scrutiny. Cute little sounds were pouring out from around the gag in his mouth as his tummy fell rapidly up and down. Finally having exposed his whole cock, Kei hooked the briefs under Tadashi’s balls, making his hips stutter once again.

Tadashi’s thighs moved easily under Kei’s guiding hands. He moved and molded them so that his puppy’s legs laid down gently on either side of Kei’s hips.

A choked complaint from behind the gag and Kei realized the new position must be shifting his tail around.

Kei reached down and gripped the base of the tail, pulling it slightly towards himself. A silent threat that he might pull it out and force Tadashi’s rim to accommodate the largest part of the plug again.

Tadashi’s face scrunched up and he shook his head, whimpering quietly.

Kei grinned, twisting it around instead and pressing the tip of the plug against Tadashi’s walls experimentally.

He could feel his puppy clamp down, but the sounds emanating from behind the gag melted from whimpers to moans.

“That’s it, puppy,” Kei soothed, his other hand massaging a freckled thigh. “Show me where it feels good.”

Tadashi’s cock bobbed as he tried to thrust into the air.

“There?” Kei slid the tail back in, fitting it snugly into that new place.

To Kei’s delight, Tadashi’s hips wouldn’t stop moving. He twitched somewhere in between consciously wagging his tail back and forth against the bed, and unconsciously reacting to being prodded deep inside.

Kei also didn’t miss how Tadashi’s spine was settled into a slight curve now, his lower back hovering off the sheets just slightly. “Good boy.”

Tadashi took a stuttering breath in. With great difficulty, he tried swallowing around the gag.

Kei’s eyes were glued to the bouncing Adam’s apple. Specifically, they were glued to the single freckle that decorated his Adam’s apple. The little dot moved as Tadashi tried to swallow over and over again.

A little droplet of drool leaked out of the corner of Tadashi’s mouth.

Kei watched it fall. His own mouth watered.

Tadashi’s back arched when Kei brushed his knuckles slowly up the underside of Tadashi’s cock. His breath puffed restlessly in and out of his nose.

Kei didn’t grip him, just ghosted over the area tenderly, trying to map out every crease and curve and freckle that made up Tadashi.

His Tadashi.

The Tadashi that had been by his side for years and had grown into an attractive young man in the meantime and who was currently pawing incessantly at Kei’s forearms.

Kei clicked his tongue, “No, no. It’s impolite to beg.” He grazed the pads of his fingers up the length of Tadashi’s cock again. “I’m just getting acquainted with you down here. I’ll get to the good stuff later, I promise.”

Tadashi whined behind the gag. His paws fell obediently to frame either side of his head, which twisted and turned from side to side, trying to get comfortable.

Kei smirked down at him.

Tadashi’s fake doggy ears flopped cutely with every turn of his head, slapping him in the forehead every now and then, and it made Kei want to tease him forever. Maybe I’ll just ghost my fingers over his dick for all eternity. Could he cum just from that if I did it long enough? What if I combined it with nipple play? Oh God I wanna find out.

No. Kei, don’t be too mean. He’s been so good. He deserves a bit of a reward.

Kei grasped the base of Tadashi’s cock and rubbed the pad of one finger experimentally over the glistening head.

Tadashi’s hips buckled, trying all at once to run away from and get closer to the sudden sensation.

Kei’s lips stretched into a thin smile. “Good boy.”

Tadashi whined, high and long, at the praise and Kei watched as he attempted to control the helpless bucking of his hips. 

“Shhhhh…” he continued to allow the tip of his finger to lazily glide over the head of Tadashi’s cock, carefully spreading the boy’s embarrassingly copious amount of precum across the entire surface; paying close attention to any shift in his hips, or small noise escaping his throat that might indicate a particularly sensitive spot.

Tadashi seemed to have three of them, one that Kei wasn’t expecting - a spot on the top, just behind his cute little slit - and two that he was - the underside of the flared ridge of his rather prominent head, and the real jackpot, Tadashi’s frenulum, which, despite the fact that he was cut, was still very much intact, so much so, that Kei was tempted to pluck it like a string, just to see how he’d react, although he refrained from doing so.

As it was, his body responded like a livewire as Kei zeroed in on it. Shushing him once more, he cupped the length of Tadashi’s cock with four fingers between his toned belly and where it stood up proudly pointing towards his navel, while his thumb worked slow, firm circles into that most sensitive spot.

He moved his other hand to grip Tadashi’s tail and began to very lightly and steadily press it to the place inside Tadashi that felt so nice, before relaxing the pressure briefly, before pressing into it once again. Not fucking him with it, exactly, but not not fucking him with it, either.

The response was immediate. Tadashi keened from behind the gag, paws flailing in the open air and breath picking up, intense and rapid and shallow. Eyes scrunched shut and face once again falling rapidly from side to side. Most deliciously, and most telling, however, was the way that the small of his back arched further, allowing Kei to more easily work the tail against the spot inside of him that he seemed to need touched most.

Tsukishima struggled to maintain his composure in the face of this response, but he managed to, seemingly entirely unmoved. He shushed his pup once again. “You like being a good boy for me, don’t you pup?” He said, lightly, almost airily. “I notice how prettily you respond when I tell you that you are, so be a good boy for me now and don’t cum. I want to watch you feel good, but I’m not done yet. So don’t disappoint me. Be a good boy and control yourself.”

Kei couldn’t, however, keep himself from coloring at the shift in Tadashi’s behavior in response to the command. He began to nod desperately, rather than throwing his head from side to side, and to give small, high whines over and over as he began to paw at Tsukishima’s thighs, rather than into the open air.

Kei huffed, still paying intent attention to his body’s other, involuntary reactions to the pleasure that he was forcing out of him. The way is freckled belly rose and fell rapidly as he breathed, the tears that had begun to leak out of the corners of his eyes as he continued to try so hard to obey Kei’s demand, the way his thighs trembled more and more uncontrollably the longer Kei kept the stimulation up, the way he could see Tadashi’s hole clenching and releasing around the plug filling him, the way that that clenching slowly began to cease and still, and most tellingly, the way that his balls, large and tight as they were, began to practically dance in his hairless scrotum with every breath.

Intrigued, Kei started to allow his thumb to brush against the soft flesh there, whenever he pressed the plug lightly back into Yamaguchi’s needy hole that was growing more loose and pliant by the moment.

Tadashi’s entire body shook like a leaf.

Kei couldn’t think of a more delectable sight. A feast was laid out before him in the form of his best friend open and wanting and obeying. And Kei had no idea where to go next.

Or, rather, Kei had so many ideas that they were fogging up his mind. He could lean over and take a pert nipple into his mouth to add to the concoction of stimulation, but he doubted that his puppy would be able to hold out, no matter how much he wanted to. He also toyed with the idea of completely stopping just to see his partner beg and pout. But Kei would effectively also be blue balling himself at that point and that didn’t seem like a good time.

Kei flicked his thumb over Tadashi’s frenulum again, making sure to keep the touches light and soft with just a hint of pressure.

Tadashi whined. The leather paws housing his hands shook and Kei realized that Tadashi’s fingers were going crazy, trying to grab at something, anything. Instead, Tadashi’s paws swept helplessly over the bed until they landed cutely on Kei’s wrists.

He couldn’t grab Kei, but instead he chose to paw gently at the source of his pleasure.

It was a miracle the touch was so soft when the rest of Tadashi’s body spasmed violently under Kei’s hands.

“Is it getting to be too much?”

Kei pressed the tip of the plug harshly against that little spot inside and Tadashi’s back arched, loud broken cries echoing when Kei’s thumb took a teasing little journey over the head of his cock.

More pressure to that surprisingly sensitive spot at the tip of his slit.

Tadashi leaked openly and Kei had the time of his life running his fingers through it and trying again. He wondered a little sadistically just how close he could get Tadashi to the edge without spilling over. Just how much precum could he leak before he became too sensitive and gave out?

“Don’t get too excited, puppy. You want to be good, right?” Kei knew he was setting up an impossible task. But the fact that Tadashi was trying so hard to obey even in the face of failure made Kei giddy with power. He was tempted to force Tadashi over the edge (or at least ruin his orgasm) just so he could find out how Tadashi would react to punishment.

But Tadashi sniffled brokenly and locked his eyes on Kei.

Kei’s heart fluttered and his fingers stopped.

Tadashi’s blushing face was streaked with tear tracks. His gasping chest rosy-red to match. Hair stuck up from where he’d given himself tangles while thrashing against the bed. His fake dog ears were crooked. Drool ran down to his jawline.

There was nothing Kei wanted more at that moment than to devour Tadashi whole. But he took in his puppy’s watery eyes and shaking arms. “Tadashi, are you okay?”

Tadashi’s eyes widened, his puppy-fog clearing just enough to become self-aware again. His paws tapped reassuringly on Kei’s wrists. He nodded vigorously before turning his eyes down onto himself and shyly looking away. His hips rocked upwards encouragingly and his face turned a deeper shade of red.

Kei’s face split into a wide grin and his fingers started up again with a vengeance. “You were gonna wear this to the party? In front of all of our friends? Are you really that starved for attention?”

Tadashi’s soft belly desperately pumped air in and out. His paws covered his own face and he whined pitifully as if to say, Don’t look at me like that!

But Kei couldn’t stand for that. “No, you’re not starved for just any attention. You want everyone to know that you’re a helpless little puppy, huh?”

Tadashi’s hips rocked upwards again.

Kei gave one final massage to Tadashi’s cockhead before journeying back down to his frenulum and committing to pushing him as far as he could go. His goal became pouring as much pleasure into Tadashi’s little body as was physically possible so that he was overflowing.

“But it’s not just that, is it,” he asked softly, with a touch of tenderness that surprised even himself. Tadashi made a small, desperate, needy sound at his tone and started rolling his hips more consistently. Whether he was doing so helplessly or on purpose Kei couldn’t tell, though he supposed that it didn’t matter.

He stilled his own movements and then pulled away entirely. Tadashi looked at him and growled around the gag in his mouth. Kei chuckled and stood up, stripping the pup of his briefs as he did so. “Don’t worry. I’m just shifting us around some, pup. I want to watch you.”

Tadashi gave him an inquisitive look that shifted to one of excitement and eagerness as Kei began pulling off his shirt and then his pants. Tadashi’s eyebrows shot up at the light pink boxer-briefs with white piping that this left him in, but Kei just shrugged before reaching over and wrapping the leash around his hand several times before gripping it right below the tag on Tadashi’s collar.

He tugged lightly on it twice, prompting Tadashi to sit up. Kei kept directing him, moving him off the bed entirely. A moment later, Kei was sitting down, left leg off to the side, right one propped out in front of him.

He pulled Tadashi’s neck forward until his face was just several inches from Kei’s own and held him there, the puppy’s paws resting on either side of him on the bed. He continued to use the leash to control him, until his pup’s crotch was settled against Kei’s hard thigh. 

Kei smirked as he felt Tadashi rut into the contact, his pup’s breath hitched as color rose high on his cheeks and he looked away guiltily, even as he continued to work his heavy, leaking cock against the warm, solid surface of Kei’s leg, groaning as he did so.

“There we go. Someone’s being a bad pup now, aren’t they?” Kei cooed. Tadashi screwed his eyes shut and whined, nodding his head miserably. “That’s okay.”

He allowed his free hand to card softly through Tadashi’s hair, brushing it away from where it had fallen over his face. “You’re a puppy and puppies are shameless. I’m going to keep you right where you are and watch you do your best to cum all over my thigh. Would you have done this in front of everyone at the party if I had worked you up enough? I never would have thought so, before I saw you like this tonight, but now? Seeing what this does to you? I actually think that you might. Maybe one day we’ll find out.” He paused. “Because you do want them to see you like this. To know who you really are. But that’s not all of it. That’s not even what you really want them to see.”

Kei’s thumb idly stroked the tag dangling from his pup’s collar, his thumb ghosting over the word engraved there in bold, black letters. “What you really want is for them to see who you belong to, to understand that you’re mine.” His thumb brushed the tag, causing it to clink gently and Tadashi groaned and shuddered at the sound. Kei felt his pup’s cock finally give, as his hips stuttered and wet streak after wet streak shot across his skin.

A brown head of hair thumped onto Kei’s shoulder and he could feel Tadashi shaking.

His puppy’s insatiable hips still canted weakly against Kei’s sticky thigh even though he’d already milked himself dry and his cock was softening. He whined around the gag as if it he had to ask permission to stop. Please, it’s too much! Please let me stop!

So Kei let his grip on the leash loosen, granting permission to relax.

Still, Tadashi’s hips kept grinding desperately.

Into overstimulation, huh? Kei smirked to himself, trailing down Tadashi’s neck to his thick red collar, the tags clinked again and Tadashi shivered. But this time his fingers continued down a freckled chest until he landed on hard nipples. He gave an experimentally soft flick.

Tadashi gasped and his hips stuttered. His head shot up and he examined Kei’s face blearily.

Kei smiled. “Oh, did you think we were done?”

Tadashi shook his head no , eyes returning to his comfortable, soft focus. Then the whimpering started again.

Kei’s heart soared around the room. “Shh, I’ll take care of you. Puppies are too dumb to be in charge, anyway.”

Tadashi gurgled out a whine and humped his leg again.

Kei snaked his hand down Tadashi’s deliciously curved back until he found his ass.

Tadashi’s hips stuttered, undecided on whether to continue overstimulating himself or whether to push back into Kei’s waiting palm.

He didn’t give his puppy time to ponder it. I promised that I would think for him, anyhow. It’s the least I can do.

Tadashi’s back arched when Kei took hold of his tail and started adjusting it inside of him. His breathing was hard and fast.

Kei shifted the tail gently and took his time teasing his puppy’s walls as he flipped the tail, so it was pointing up to the ceiling. Easier to see him wagging, now. 

Kei smiled at how enthusiastic and eager-to-please the tail looked.

He gripped the leash again and tugged him gently backwards.

His puppy got the message and pulled himself mournfully away from Kei’s body. He let himself be maneuvered into kneeling on the ground.

Kei regarded him carefully, letting his eyes wander over every inch of Tadashi’s trembling form. Probably still in post-orgasm haze. But the curious thing was how Tadashi hadn’t demanded to be freed yet.

He wasn’t pawing at his gag, or grunting about the tail, or even protesting about the collar. It was like he… wanted to stay like this.

Kei slowly, thoughtfully, brought one leg up, draping it over Tadashi’s rosy shoulder.

The puppy immediately started nosing at it lovingly and Kei had the feeling if his gag was gone, Tadashi would be licking him like a happy dog. It was a glorious mental image.

But he had something better in mind. Kei reached for his discarded shirt and casually cleaned Tadashi’s cum off his own leg. 

He watched out of the corner of his eye as his puppy got a panicked look on his face as if to say, Wait! We’re not done, right?? I don’t wanna be done!

Kei laughed to himself. “Don’t worry, puppy, we’re not done. I still need to get off.”

Tadashi’s eyes went wide and he scooted forward on his knees eagerly.

Kei couldn’t stop giggling out loud at that. “Okay okay.”

He pushed Tadashi’s head down, like he was bowing to Kei, so that he could undo the gag.

“Here, you have to promise to be good, though.” He mock-threatened. There was no doubt in Kei’s mind that Tadashi would keep obeying him blindly. It was invigorating.

As soon as the gag fell away, Tadashi dove forward, licking desperately at the thighs framing his head.

Kei let him, watching semi-mesmerized as he placed the gag down on the bed.

It wasn’t long before Tadashi was nosing needily at Kei’s clothed cock.

He should have expected that Tadashi would get messier and less aware. But it still caught him off-guard when Tadashi started mumbling again without being granted permission.

“Please,” Tadashi slurred against Kei’s thigh. “Wanna… good… I’m good. I… please.”

Kei’s heart clanked against his ribcage before shooting down into his dick.

Tadashi picked up on the subtle change--of course he did, Kei should’ve expected that being friends for so long would lead to this--and started mouthing greedily at Kei’s length.

His breath stuttered as warm, wet teasing fluttered along his most intimate areas. Kei didn’t know he wanted this badly enough to short-circuit. “T--Tad--ngh.” Before he knew what he was doing, he jerked mindlessly at the leash, pulling Tadashi directly up against his cock.

And he didn’t need any more invitation. Tadashi pawed at Kei until he pulled himself out of the fly of his underwear and swallowed him down.

Kei’s entire being curled forward, hand helplessly burying in Tadashi’s hair as he went to work sliding easily over his dick. His knuckles turned white as he gripped the leash in his other hand.

Tadashi whined, high and needy.

Color burst behind Kei’s eyes as the back of Tadashi’s throat constricted around the head of his cock. He was probably making noise. Probably making a damn fool of himself. But all he could hear was Tadashi.

Tadashi sucking him down, not even bothering to tease. Just greedily devouring him and… and… enjoying it. He whimpered through his nose, vibrations rocking Kei to his core.

Kei yanked on the leash weakly, directing Tadashi to go faster faster faster please faster more oh god too much too much ngh nnh no wait--

Kei’s back shot straight as a dam broke and pleasure flooded comfortably into his stomach. He caught the perfect view of Tadashi swallowing eagerly, little paws gripping into pale calves and tail wagging against the floor.

When he came back to himself, Kei’s voice was hoarse. “Good boy,” It didn’t sound powerful or dominating or sexy. Just broken.

But Tadashi pulled off Kei’s dick and lept into his arms, a frenzy of happy sobs.

A tangle of limbs and leash and crooked fake dog ears as Tadashi tackled them both backwards onto the bed.

He nuzzled happily into Kei’s neck and almost crushed Kei’s ribs in a powerful hug.

Kei could hear himself croaking out weak laughter as he petted happily into Tadashi’s brown hair. “So good for me.”

Tadashi nuzzled closer, murmuring sweet words that Kei couldn’t make out.

It didn’t matter. They would talk more later. Fuck the Halloween party. Tadashi was always more fun than anyone else had ever been. “Good boy. So good. The best.”
