Work Text:
“Hyungie..?” Gunwook’s voice sounded so small when he appeared at the door to Matthew’s home office, Matthew immediately abandoned whatever work task he had been completing on his computer. It couldn't be more important than comforting his boyfriend.
“Hey baby,” he smiled, “I didn’t hear you come home. Is it that late already?” A quick check of the time on his computer told him that in fact, it wasn’t late enough for Gunwook to be home from classes yet.
The younger one just shook his head, fully coming into the room now and closing the door behind him to lean against it. His shoulders were rounded forward and his big hoodie seemed to swallow him. Like he was trying to appear smaller than he was.
“I’m skipping,” he confessed, looking at Matthew from beneath his bangs to gauge his reaction.
“What’s wrong?” Matthew immediately asked, his brows furrowing. This wasn’t like Gunwook. He took his master's degree very seriously, assignments always on time and never skipping even his most boring 8 am statistics courses despite Matthew’s whining.
“I’m-,” Gunwook fiddled with the sleeves of his hoodie, the fabric already looking frayed like he had been playing with the seam all day already.
“Come here,” Matthew prompted him, opening up his arms for Gunwook to climb into. The other immediately moved to wrap himself around his boyfriend, burrowing his head in Matthew’s neck.
Despite the tight fit on his desk chair and the concerning noise it made, they made it fit. Gunwook’s body seemed to lose some of the tension when Matthew’s hands found their way into Gunwook’s silky hair.
“Will you tell me what’s wrong?” Matthew asked quietly after a while.
“My… I think my headspace is lingering,” Gunwook mumbled, “I feel ready to slip any moment.”
The words had Matthew’s grip on Gunwook tightening. This was serious. It wasn’t safe for Gunwook to be out in public when he felt like this. Immediately, Matthew felt his focus shift, his work became an afterthought as his world narrowed down to his sub in his lap.
“Do you know why?” He asked carefully, already turning their last scene over in his head. Had he not eased Gunwook out of his headspace well enough?
“Classes just suck right now. There’s so much to do and it’s so stressful and I- I- I need this, hyungie,” Gunwook all but begged, picking up his head so he could look at Matthew. His eyes already had that slightly faraway look and Matthew couldn’t help but coo at him.
He knew this could happen. Especially with puppy subs. And he knew what Gunwook needed.
“Do you have anything you need to be doing today or tomorrow?” He asked, cupping Gunwook’s face, who only shook his head.
“Words please,” Matthew already had a feeling Gunwook would go nonverbal as soon as he fully let himself slip into his headspace so he needed to get all the information now.
“Submitted everything early. Group project can wait.”
“Thank you, puppy.” The pet name already pulled a whine from Gunwook, telling Matthew how deep he was already in his headspace.
“And what do you need from me?”
“Just you, hyungie. Need to be your good puppy.”
“You are my good puppy,” Matthew encouraged him, cupping his face to press a short kiss to his lips that Gunwook immediately chased.
“Remind me of our signals,” Matthew spoke right against Gunwook’s lips, holding him back from kissing him again.
Another whine fell from Gunwook’s lips, more high pitched than the last one and he clearly struggled to form words.
“One tap, I’m okay. Three taps, I need to slow down. Pinching, I need to stop.”
“And hand gestures if I’m asking hard questions,” Matthew filled in the rest, “Can you show me how you feel now?”
Gunwook quickly grabbed onto Matthew’s forearm, squeezing once.
“Thank you, puppy.”
“One more hard question. Do you need to just be my good puppy or do we need to go to the bedroom?”
At that, Gunwook hesitated for a moment before he held up one finger, showing Matthew all that he needed.
“That’s okay,” Matthew smiled, “And if that changes, I want you to squeeze my thigh twice, okay? Then I’ll check in again.”
As an answer, Matthew only got another squeeze.
“If you get your collar, we can start,” Matthew gave Gunwook the permission he’d been waiting for.
Almost sheepishly, Gunwook reached into the pocket of his hoodie and pulled out his pretty pink collar, all his charms dangling against the metal of the rings attached to it.
“Puppy came prepared, huh?” Matthew only mused, taking the collar from Gunwook who immediately presented his throat to Matthew.
With a deep breath to center himself, Matthew wrapped the collar around Gunwook’s throat, closing the buckle where they always had it, the leather already slightly frayed.
“Does it feel good?” He asked, pushing two fingers between the collar and Gunwook’s skin to test the give.
It was always fascinating to watch Gunwook slip into his headspace, he had that faraway look on his face like he wasn’t really there with Matthew. Almost like he had just woken up from a dream.
But his puppy quickly squeezed his arm again, a lazy smile forming on his face and Matthew was glad he already seemed to do much better now that he was allowed to let himself slip in a safe space.
“Hyungie still has some work things he needs to take care of,” Matthew explained, “And good puppies sit on the floor and wait their turn.”
He probably wouldn’t be able to focus on his work with his attention split between clients' schedules and regimens and his puppy but he had to at least try and get some more stuff done before clocking out for the weekend.
A little clumsily, Gunwook climbed down from his lap and kneeled by Matthew’s feet instead, looking up at him from his big brown eyes expectantly.
“Good boy,” Matthew rasped, willing his dick not to chub up in his sweats at the sight. That was not what Gunwook needed right now.
Gunwook’s collar jingled as they got settled with him beneath Matthew’s desk, his knees cushioned by a pillow they kept there for that exact reason and his head leaning against Matthew’s thigh.
“Comfortable?” Matthew checked in and Gunwook squeezed his calf once.
“I’ll go back to work now, puppy.” At that, Gunwook only hummed deep in his throat, the charms on his collar jingling one last time as he rubbed his cheek against Matthew’s thigh before he completely settled down.
Matthew kept one hand in Gunwook’s hair to scratch his scalp, petting him absent-mindedly like one would a dog as he went back to work.
He was almost done with creating a new diet and training program for one of the regulars at the gym he worked at when he felt Gunwook shift again. Something about Gunwook’s comforting warmth really had helped him focus and it made himself smile. They really did fit together so well.
“Still doing okay?” He asked quietly, slipping his hand down to cup Gunwook’s cheek instead. His puppy took a little longer to answer but squeezed his calf again.
“Thank you,” Matthew acknowledged, giving him a slight tap with his palm to his cheek before slipping his hand back into Gunwook’s hair.
With Gunwook’s new position, he was almost completely between Matthew’s thighs now and Matthew could swear he felt Gunwook’s soft breath ghost over his cock. Traitorously, Matthew felt the thing harden. He wasn’t going to do anything about it. But he also knew if Gunwook were to have his eyes open, he’d clearly be able to see it happen despite the darkness beneath his desk, his sweats hiding absolutely nothing.
Much sooner than last time, Matthew felt Gunwook shift again, pressing himself even closer and oh- His puppy was hard too: The line of his cock pressing against Matthew’s calf.
Before Matthew could even check in, Gunwook squeezed his thigh twice, hard and entirely too close to his dick so Matthew had to stifle a moan.
“Hmm,” Matthew hummed instead. “What does puppy need?”
He wasn’t expecting a verbal answer and was already pretty sure what Gunwook wanted but the way his puppy immediately nuzzled his face into his dick confirmed it nicely.
“Okay, puppy,” he sighed, “Let hyungie get it out for you.”
Because Gunwook was a dream, he pulled back just enough so Matthew could clumsily undo the drawstrings on his sweats and push them down along with his briefs just enough that he could get his cock out. He wasn’t fully hard yet, but that was only a matter of moments at this point.
“Go ahead,” Matthew gave his permission and Gunwook didn’t waste a single second to get his mouth on him, immediately engulfing Matthew in the warm wetness of his mouth, a satisfied groan mixing with Matthew's wanton moan.
Biting back a curse, he quickly signed out of his account, work be damned. There surely were rules that you couldn’t get your dick sucked while you worked from home.
To keep up the illusion for Gunwook instead, he opened Twitter on his laptop to aimlessly scroll through his timeline, fighting the urge to thrust deeper into Gunwook’s mouth when he only lazily held him here, barely suckling on the length like it was more to pacify himself than to please Matthew.
“Such a good puppy,” Matthew couldn’t help but praise him, reveling in the whine Gunwook let out in turn, “Keeping me nice and warm.”
The initial excitement about getting his dick sucked slowly ebbed off when Gunwook made no moves to get him off. The message hadn’t reached Matthew’s dick of course, that stayed hard on his sub’s tongue.
He had long forgone aimlessly scrolling through Twitter and instead was browsing through a BDSM shop that specialized in collars. While they both loved Gunwook’s current collar, it wasn’t the best quality. So Matthew had made up his mind to get him a new one for their anniversary: The day he had first put the collar on Gunwook.
There were lots of options but Matthew had been stuck on the tool where you could customize one yourself.
Of course, he’d keep the pretty pink color but he wanted to add silk to the inside of the leather so Gunwook’s skin wouldn’t get as irritated if he wore it for longer; There were also options to change the number of o-rings on the collar or even get something engraved into it.
While he found it incredibly hot if Gunwook were to wear his name at all times when he wore the collar out, Matthew wasn’t sure if Gunwook felt the same. He had never asked about a tag with Matthew’s name on it or anything: The only branding was the small silver fox charm dangling beside the heart charm their BDSM-club issued for newbies that Gunwook refused to take off.
Clicking through the presets, Matthew’s eyes fell on one specific engraving right between the big o-ring at the front and the smaller one to the side reading ‘good puppy’.
Judging by the surprised sound Gunwook let out, he had felt how seeing that had made Matthew’s cock twitch.
Choosing that option, Matthew put all his focus on looking through all the different types of engravings - if he wanted it on a plaque or burned or engraved into the leather - so much so that he only noticed Gunwook shifting again when his cock hit the back of his puppy’s throat.
“Oh shit, puppy,” he cursed when Gunwook held himself there, his nose pressed into the dark patch of curls atop Matthew’s dick.
“Sorry, hyungie was distracted,” he groaned, the tightness around his dick only increasing when Gunwook swallowed around him.
“Hyungie should only pay attention to his puppy, right?” He didn’t expect an answer but Gunwook squeezed his thigh once in reply anyway.
“Hyungie is sorry,” Matthew went on, quickly saving the design for later and closing the website.
“I’ll make it up to my puppy.”
With that, he slowly moved his hips up, trying to get more of that tight heat of Gunwook’s throat when realistically, there wasn’t more for the sub to take.
“That’s it,” he sighed when Gunwook just let him do whatever, holding still and steadying himself with his palms on Matthew’s thighs.
“Such a good puppy, taking me so well,” Matthew couldn’t help but run his mouth when Gunwook felt so perfect, taking the deep thrusts Matthew was giving him without gagging a single time.
They had put so much work into this and it really paid off for Matthew.
Only when he picked up his pace: Going from languid and long strokes to jerking his hips up quicker, did Gunwook choke and splutter but never pulled away, drool dripping down Matthew’s cock and into his sweats.
“Come on, puppy,” he urged Gunwook on, “Don’t you want to have hyungie’s cum?”
That pulled a high pitched whine from Gunwook’s throat. His puppy always wanted his cum. Sometimes Matthew thought it might be more important to Gunwook that Matthew came during a scene than himself.
With another squeeze to his thighs, Gunwook really got to work: Bobbing his head up and down Matthew’s cock and working his tongue over the sensitive spot just beneath the crown before he forced himself down all the way again.
“So good, puppy,” Matthew moaned unashamedly, “Making hyungie feel so good.”
Oh, how badly he wanted to see Gunwook right now with his pink lips stretched around Matthew. Was he being so messy again that his spit was bubbling up? Were his eyes closed in concentration or would he look up at Matthew with tear filled eyes?
“Fuck, puppy. Hyungie wants to see you.”
Immediately, Gunwook scrambled to push Matthew’s chair back and crawl forward without ever taking Matthew’s dick out of his mouth.
And fuck, did Gunwook look gorgeous. His eyes immediately found Matthew’s and what he must’ve seen, pulled a deep moan from him, muffled by Matthew’s cock that was still between his lips.
Just like Matthew had thought, Gunwook had made a mess since he never bothered to swallow his saliva, knowing they both liked it wet and messy.
“Such a pretty puppy,” Matthew praised Gunwook immediately, pushing his bangs from his face tenderly. His whole face had a pretty pink flush, matching his collar.
At Matthew’s touch, Gunwook let his jaw fall slack, his eyes pleading.
“You want hyungie to fuck your throat?”
Matthew knew he should have waited for confirmation but instead, he just meanly fucked his hips up, the angle wrong so Gunwook immediately choked on the intrusion, more saliva dripping down and bubbling up as he coughed around Matthew.
“Keep still,” Matthew warned him, waiting until Gunwook had stopped coughing before cupping both his cheeks with his hands to keep him in place.
“Pinch me if it gets too much,” Matthew barely remembered to remind Gunwook before he let his pleasure take over, fucking into Gunwook’s waiting mouth and throat with a single-minded focus to cum.
It never took long like this.
The tears streaming down Gunwook’s face only served to turn Matthew on even more, to push his sub further until he had to close his eyes to focus on breathing through his nose whenever Matthew allowed him to.
“Hyungie is so close,” Matthew blabbered, “You’ll be a good puppy and take what hyungie gives you, right? Good puppies don’t waste a single drop.”
When Gunwook squeezed his thighs again and forced his eyes open and up to look at Matthew, it was over for him. With a drawn out groan, he pushed Gunwook down on his cock again and spilled down his throat, a guttural moan leaving his lips.
“So good,” he heaved, his eyes never leaving Gunwook’s who whimpered when spurt after spurt of cum went down his throat.
“Hold it,” Matthew demanded, keeping his grip tight on Gunwook’s head when he tried to let up. Riding out the last waves of his orgasm, Matthew gently thrusted into Gunwook’s abused throat until the stimulation became too much for him.
Only then did he pull Gunwook back slowly until his dick fell from his lips with a wet pop.
“Show me,” Matthew heaved.
Gunwook easily opened his mouth for Matthew, stretching his tongue out wide. Of course, there was no trace of Matthew’s release but this was their ritual.
“Good boy,” Matthew praised, gently closing Gunwook’s jaw.
For a moment, it was quiet between them. Matthew always had to collect himself after cumming, keeping his head in the space that he needed to be in to take care of Gunwook. They weren’t done after all.
“You want to hump hyungie’s leg or have hyungie’s hand to finish you off?” Matthew asked, still breathless when he felt Gunwook roll his hips against his calf.
His puppy quickly held up two fingers for him and with a smile, Matthew patted his lap for Gunwook to climb up.
The chair protested under their combined weight but neither paid it any mind when Gunwook shoved his pants down so his cock could spring free, the head shiny with precum and an almost angry dark pink shade.
“Puppy won’t need much, right?” Matthew teased him, wrapping both hands around Gunwook’s big cock to stroke him with tight fists.
Despite his trembling thighs, Gunwook held perfectly still and let Matthew set the pace.
“You can cum whenever you want,” Matthew allowed him, “You were so good for me. My perfect little puppy. Took everything I gave you so well and made hyungie feel so good.”
When Gunwook wouldn’t meet his eyes and just stare at his lips, Matthew knew exactly what he needed and leaned in to meet him in a messy kiss that his puppy immediately moaned into.
Just like his blowjobs, there was too much spit involved when Matthew pushed his tongue into Gunwook’s mouth, letting his puppy suck on it before he pulled back slightly to speak against his lips: “Hyungie wants to see you cum, puppy. You’ve been so good. Let hyungie see.”
With a loud whine and a couple of jerky thrusts of his hips, Gunwook finally fell apart, shaking in Matthew’s lap as he came all over Matthew’s hands who tried his hardest to catch everything so they wouldn’t ruin their clothes as he worked Gunwook through it but his puppy just always came so much.
“That’s my good puppy,” he kept praising him, “You came so much for me, thank you.”
“Hyungie,” Gunwook whined, weakly finding his voice. He still hadn’t stopped cumming, his cock weakly spurting out more when Matthew kept massaging around the head.
“Is it too much?” Matthew checked in but kept going when Gunwook shook his head, his eyes screwed shut tightly.
It hit Matthew what was happening when Gunwook suddenly let out another deep groan and his thighs spasmed around him again, his dick continuously drooling out more cum.
“Oh fuck, puppy, you’re perfect,” Matthew cursed. Gunwook had been so wound up, he had barreled straight into a second, almost dry orgasm just from getting his dick played with.
Gunwook only whined, looking down at his dick that was slowly softening in Matthew’s grip, messy with his own cum.
With a devious smile, Matthew brought one of his hands up to his own lips, licking the mess from his fingers.
At the sight, Gunwook quickly surged forward to grip Matthew’s wrist before he smashed their lips together to lick his cum from Matthew’s tongue.
“Mine,” Gunwook all but growled, the sound going straight to Matthew’s dick as he watched Gunwook suck each of his fingers clean before running his tongue over his palm and cleaning his other hand as well.
Once he deemed Matthew clean enough, Gunwook showed him his tongue again.
“All gone,” Matthew confirmed with a smile, closing Gunwook’s jaw and pressing a sweet kiss to his cheek.
“You feeling better?” Matthew asked quietly, carefully pulling Gunwook’s briefs and pants up again so his dick wasn’t hanging out anymore.
Gunwook only nodded, his body melting into Matthew’s. With his pointer finger, he drew a heart shape onto Matthew’s forearm.
“I love you too, puppy,” Matthew chuckled, winding his arms around Gunwook so he wouldn’t slip off the chair.
“How about we take this to the sofa and I make you a hot chocolate?” Matthew suggested when his legs started to feel slightly numb.
It seemed like Gunwook had slightly dozed off with how long it took him to squeeze around Matthew once and collect his limbs off of him.
“Let me clean you up first,” Matthew stopped Gunwook, grabbing some tissues from his desk and carefully wiping the mess of tears and saliva from Gunwook’s face.
“You’re so goddamn pretty,” Matthew found himself saying when Gunwook expectantly looked at him with a slight pout on his lips once he put the tissues down.
Leaning down, Gunwook left a feather light kiss on Matthew’s lips before he dropped to his knees again: Good puppies didn’t walk, they crawled.
Pulling up his pants as well, Matthew led Gunwook to their living room, patting the cushions like he was inviting Gunwook up, covering him with a fluffy blanket when he had settled.
“I’ll get you your treat,” he mumbled, kissing Gunwook’s forehead.
But he didn’t get far, Gunwook holding him back around the wrist.
“What is it?”
Matthew wasn’t sure why he asked, Gunwook clearly wouldn’t speak but his sub drew another heart on his wrist.
“I love you,” Matthew said again, “I’ll make it quick.”
This time, Gunwook took a deep breath before nodding and releasing Matthew’s wrist.
Matthew didn’t like to be separated from Gunwook either when he was still so deep in his headspace but he also needed him to eat and drink something so he quickly dashed into the kitchen to grab a chocolate milk and some snacks.
Once he was back, he immediately cuddled into Gunwook’s waiting arms and gladly pampered him by hand-feeding him the snacks and holding the carton as he drank his chocolate milk.
“Thank you,” Gunwook mumbled after a little while of Matthew just patting his belly.
“You’re welcome,” Matthew smiled, letting Gunwook squeeze him so tight, he got lightheaded for a moment.
“Needed this.”
“I’m here for you, puppy,” Matthew reassured him.
“Just a bit longer?” Gunwook all but pleaded.
“As long as you need to, I’m here,” Matthew promised, “I’ll text Ricky that we’re staying home tonight. I just want it to be the two of us.”
“Thank you, hyungie,” Gunwook sighed, nuzzling further into Matthew like he was trying to melt their bodies together, drawing heart shape after heart shape on all parts of Matthew he could comfortably reach.
