A few days passed and Derrick found he was a lot more clear-headed at work, where the little things that were really starting to get to him were back to being an afterthought. Morning coffee with William returned to being comfortable, casual, and enjoyable! Day after day, returning to his desk, doing his job. Noting the subtle change in William's demeanor as time went on, savoring it when he would walk into the meeting room without that chipper smile curling up his lips, his tail sullen and motionless behind him and his shoulders slumped. Derrick wouldn't lie to himself and say he didn't take some satisfaction in it. Everything was going as planned; Spencer's scheme was playing out exactly as he had told Derrick it would. If anything, the Doberman underplayed his manipulation skills. Each little seed of doubt that he had planted in Derrick's mind about Will's character and intentions seemed to be blooming into a healthy crop of resentment and betrayal.

As the days went by, Will's mood worsened with each setback at work and each private phone call he thought he had discreetly taken. Derrick found himself smiling on the inside, even as he acted the part of the concerned and supportive subordinate. He'd pat Will on the back and offer encouraging words, all the while relishing the golden retriever's mounting misery. Spencer, for his part, would check in with Derrick periodically, either through brief texts or late-night phone calls, congratulating him on his progress and reminding him of the prize that awaited him once their plan came to fruition. Derrick would methodically document William's frustration, going so far as to surreptitiously snap pictures and videos of the retriever and send them to Spencer. The Doberman's praise felt like a drug to Derrick, filling him with an intoxicating mix of pride and determination to their plan.

It's been a week since Derrick agreed to Spencer's twisted plan and things couldn't be going any better. The golden retriever was slowly but surely spiraling downwards, his once cheery demeanor fading away day by day. Their morning coffee breaks had become one-sided affairs with Will barely uttering a word, lost in his own thoughts as he stared into his cup of steaming joe. A part of Derrick still felt some guilt gnawing at him but he pushed it down – Spencer's words ringing in his ears: "You deserve better than this. Letting him wallow in his fantasy is cruel."

Today was different; however, Will didn't even bother putting up a show for their usual routine. Assigning Derrick some menial task was all the golden lab could muster before retreating back to his corner office. The shepherd watched as William shuffled back into his office wondering how far things had gone. Spencer mentioned that his plan had already started by the time he jumped on board with it. Had Spencer revealed what he had been doing with the lab's wife yet? Did he know he wasn't going to get the promotion? For all intents and purposes, William looked like his same old self during work hours for the most part. It was only because Derrick had spent so much time getting to know the lab did, he know how to read the man's subtle body language. Derrick tried to focus on his work, but his mind kept wandering back to William. He couldn't help feeling a pang of guilt. Maybe he had gone too far by helping Spencer sabotage the poor guy. After all, William had always been kind to him, and was a decent boss overall. But kindness could only get you so far, the shepherd reminded himself. He had to hold strong. Showing weakness in their world was akin to asking to be stabbed in the back, as William had unknowingly demonstrated.

Derrick was so lost in thought that he didn't even notice William emerge from his office and head towards the breakroom. On impulse, Derrick got up and followed him. He found William sitting alone, staring blankly at a cup of coffee.

"Hey Will, you doing alright?" Derrick asked gently.

William glanced up, looking exhausted. "Oh, hey Derrick. Yeah, I'm fine. Just have a lot on my mind lately."

Derrick sat down across from him. "Listen, you I'm here if you ever need someone to talk to. I can tell something's really eating at you."

William hesitated, then gave a sad smile. "I appreciate that. You're a good guy, Derrick." He took a deep breath. "Truth is, my personal life is kind of falling apart. My wife and I have been fighting a lot." William looked down into his coffee cup, clutching it tightly with both paws. "I think she might be cheating on me," he said softly. "I've suspected it for a while now but haven't wanted to believe it."

Derrick felt a pang in his chest. He had helped facilitate this, at Spencer's direction. "Gosh William, I'm so sorry," Derrick said, reaching out to put a paw on William's shoulder. "That must be really painful. Do you have any proof?"

William shook his head sadly, his tail twitched back and forth anxiously. "Just a feeling. She's been distant, working late more often. I saw a message pop up on her phone from a number I didn't recognize, but when I asked about it she brushed it off." Derrick watched, he saw uncertainty in his mentor's eyes. He truly was at a loss.

“Well well if it isn't my two favorite furs! I didn't know we were having a pow-wow in here! I'm hurt, no one thought to give ol' Spence a shout out?" The Doberman interrupted. He strode in confidently giving Derrick a subtle nod. From where he was sitting Derrick could see William freeze. Spencer sauntered into the break room, his usual cocky grin plastered across his muzzle. William tensed at the sight of the Doberman, his ears flattening against his head. "Don't let me interrupt boys, sounds like you were having quite the heart-to-heart," Spencer said as he helped himself to a cup of coffee. William averted his gaze, but the Doberman either didn't notice or didn't care. "So Willy, rumor has it things aren't going so hot at home. The missus stepped out, huh?" Spencer prodded.

William clenched his jaw, staring down at the table. "It's William..." Derrick could hear the weakness in his voice.

"That's really none of your business, Spencer," Derrick interjected, trying to intervene. He had to keep up appearances.

"Oh come now, we're all friends here! I'm just concerned for poor Willy," Spencer replied. He sat down at the table next to William, draping an arm over the golden retriever's shoulders. William cringed at the contact. "Chin up buddy, you'll get through this. And you got ol' Spence here to help however I can. Spencer said with a smile. Derrick knew it was really a dig at William's situation. He was the root of all of this after all.

Derrick felt a wave of unease wash over him as he watched the interaction between Spencer and William. Though he had been complicit in the Doberman's schemes up until now, seeing the defeated look on his mentor's face gave him pause. This was not the outcome he had envisioned when he agreed to help Spencer undermine William's position at the company. At first, it had seemed harmless - just a few minor sabotages to impede William's chances of getting the promotion he was hoping for. But now, as Derrick saw the toll it was taking on the kind-hearted retriever, he realized things may have gone too far.

William stood up abruptly, mumbling some excuse about needing to get back to work. As he shuffled out of the break room, shoulders slumped, Spencer shot Derrick a sly grin.

"Poor sap doesn't know what hit him," the Doberman chuckled. "At this rate, he'll be out the door in no time, and that promotion will be all mine."

Derrick nodded half-heartedly. Inside, his conscience was screaming, but he pushed it down. This is what it takes to get ahead in business.

With only weeks before the company had to announce who would be filling the prestigious position of Senior Partner, Derrick perked up when he got an e-mail from William telling him to come to his office. It was strange because Derrick was certain the lab had left for the day, since the office had closed over an hour ago. The cleaning staff were shuffling into the building. With a shrug he got up from his chair and made his way over to the corner office, noting that the blinds had been drawn, although that had become more of a common occurrence over the past week or so.

After knocking on the door, the shepherd heard William awkwardly clear his throat before welcoming him in. The younger canine let himself in with a casual smile. "Hey, William! You, uh, alright? You are usually one of the first people out the door ever since I started working here." The shepherd awkwardly chuckled, clearly worried.

The yellow lab was standing near the large floor-to-ceiling window that lined one of his office walls, "Mmh? Of course. Something came up that could only be dealt with later than usual is all," he reassured the younger canine, who closed the door behind him and stepped up to stand next to the other, older canine, and watched the sun slowly dip into the horizon.

"Well, I'm glad to hear you're alright. Is there something I can help you with then?" the shepherd asked, trying to figure out why he had been called in here. He was waiting for the lab to inevitably reveal some tedious task that would keep him here well into the evening, patting him on the back and chuckling his way out of that office while babbling something about building character.

The lab stared off, gaze distant as he nodded slowly, as if considering his words carefully before those warm eyes that Derrick had fallen in love with gazed his way. "Before that, I need to be perfectly clear, Derrick. I respect you as my equa— as my." The lab shook his head, choking down the words. Composing himself he started again, “and I would never want to do anything to jeopardize our working relationship. That said, if you feel uncomfortable with anything I'm about to say to you, please! Feel free to step right out that door and we can forget this whole thing happened…sir" The lab looked desperate letting an unnatural pause linger to punctuate his sentence, as if he was trying out the feel of the word in his mouth. Derrick wasn't sure if he heard him properly at first, did Will just call him sir? Looking back at Will, his face looked so desperate in that moment that Derrick had never seen before. Was this Spencer's doing? Did the Doberman put the Will up to this? It felt strange yet also intriguing. He studied Will's face, seeing the desperation and unease in his eyes. There was clearly more going on here.

"What is it, Will?" the canine asked, turning his head to face the lab who focused intently forward, seemingly unable to meet the other male's gaze.

William took a deep breath before continuing. "I..." William mumbled, clearing his throat again before narrowing his gaze, "You are a very attractive young man, Derrick..." The shepherd's heart skipped a beat. What was going on? "You have worked so hard for me. Given so much. I would like to... Give back." The lab spoke softly now, ears folded back, tail tucked as if the words had been extracted from him with pliers. Some part of the shepherd could see Spencer's paw in this. The Doberman must have orchestrated this somehow.

Derrick's breath caught in his throat, Spencer's words from that day, weeks ago, ringing through his skull like a church bell: "All you need to do is take what is yours and you will have everything you deserve." This was it! Spencer's plan! Derrick didn't think Spencer would go this far. And how had he even managed it? If he turned and left, right now, Will would be spared a large portion of whatever plan Spencer had cooked up. They could continue on with their professional lives together. Derrick respected William. Truly. He wanted to give the lab what he practically begged for moments ago, secretly: to leave. The exit wasn't so much a lifeline for him as it was for William. He was tempted to. To spare Will. For things to be normal.

But Derrick wasn't happy with normal. He knew that and, after a slight pause, the two canines' breath catching in their throats for different reasons, he reached over slightly, gripping the older male's wrist hard and guided Will's paw to his crotch. "I'd like that too, Will." Derrick said, lips curling up into a slight grin. The intern could see his boss's eyes widen for a single moment before flicking down slightly, expression shifting subtly enough that if Derrick didn't know him, he wouldn't have caught the disappointment and the terror.

William felt a surge of heat rush to his cheeks as Derrick tightened his grip on his wrist, guiding it to the growing bulge in the younger dog's pants. He couldn't believe this was happening. His heart raced, but not with the usual comfort and fondness he harbored for the shepherd. No, this time it was tainted with something else entirely: fear. Spencer's words from their meeting earlier that day echoed in his mind, playing on a loop: "Make sure you put on a good show for your little protégé" The rest of threat went unsaid, the silence hanging in the air had been clear enough, and William knew better than to cross Spencer with all that was going on. If his head had been clear he would have told the Doberman to fuck off, but somehow the other canine seemed to have a window into the labs troubles.

Reluctantly, William began to stroke Derrick through his pants, his movements slow and hesitant at first, as if he could somehow undo this entire situation by taking his time. But as he continued, a part of him began to respond against his better judgment. Derrick's arousal was obvious through the fabric of his pants.

As William's strokes grew a little bolder, Derrick met his eyes, his own blazing with a newfound hunger and determination. "That's it… bitch." The shepherd growled, the slur hitting him like a slap in the face. The disrespect should have enraged William, but instead, it sent a shiver down his spine. William swallowed hard, thoughts warring in his head. This was wrong on so many levels. He was the mentor, the boss... the one in charge! But at the same time, Spencer's threat lingered in his mind. He couldn't risk everything he had worked for just because of some twisted sense of morality.

Reluctantly, he unzipped Derrick's pants, exposing the hard length straining against the thin fabric underneath. Derrick stepped closer, pressing their hips together. "That's it... show me who's boss." He whispered in William's ear, his tone dripping with sarcasm as he guided the lab's hand to grip him firmly.

The office went quiet after that, the slow, sensual sound of cloth shuffling as Will massaged Derrick's crotch. The lab looked...uncomfortable, or perhaps he was just inexperienced. But after a few moments he finally reached for the fly of the shepherd's pants and tugged it down. Derrick stood there, slowly leaning back to sit on the edge of Will's desk as his pants were tugged open and his boss slowly sunk down onto his knees in front of him, freeing up the view of the sun setting behind the city buildings behind him. Derrick cut the silence by heaving a long, content sigh of relief as his aching, heavy erection slipped free of his underwear. He did his best to keep himself tidy and clean, mentally relieved with the lab didn't recoil from his throbbing erection in disgust.

In the dimly lit office, Derrick watched intently as William hesitantly knelt before him, his eyes locked on the unfamiliar sight below. The warmth of the lab's breath washed over his length as he inched closer, the anticipation electrifying every nerve. William's tongue flicked out to moisten parched lips, his heart pounding in his ears like a drum as he brought his muzzle close. He inhaled deeply, drinking in the musky scent that hung heavy in the air between them. Slowly, tentatively, he wrapped his soft lips around Derrick's throbbing shaft. Heat and wetness enveloped the shepherd's sensitive skin, threatening to send him over the edge right then and there.

Derrick gripped the edge of the desk for support, his claws sinking into the polished wood as William began to move, building a rhythm that matched the pounding in their chests. Up and down the lab's mouth bobbed, reshaping itself around every contour of Derrick's length. Derrick, who by no means was a virgin, was slightly surprised by the ease that the straight, married man kneeling in front of him took that glistening red cock into his muzzle. Derrick's head fell back, eyes closing as he almost saw stars. Will's mouth felt like nirvana wrapped around his cock, the obscenely wet 'slrrrp!' of his boss's lips dragging across his sensitive flesh brought both of his hands to grip the edge of the desk. Derrick moaned, perhaps a bit too loudly, his toned frame shaking slightly as he already began to drip pre onto Will's tongue.

Will's eyes were shut, that yellow-furred muzzle bobbing up and down Derrick's cock, "O-oh god-! Will~!" Derrick's voice shook, beginning to pant softly. The yellow lab did not respond, seemingly focused on his task-- which he was doing very well! His pace quickened and the office filled with the wet slurps at an increasing pace of 'slrp! slrp! slp!' Will's hands massaged the shepherd's thighs gently as he occasionally paused to gulp down the pooling pre in his muzzle before it would drip over his lips. Derrick's hips began to buck forward occasionally adding the occasional 'glk!' and gagging noises as that fat, drooling tip of his cock pressed insistently into the back of Will's throat. Determined to take the reins of the situation, Derrick reached down and gripped each side of the lab's head, taking over the pace for the canine, forcing him to bob in time with his hands, to slow the dog down and let him enjoy this a little more thoroughly. Some small part of Derrick terrified that he'd wake up in his room at any moment or that he'd be fired by the end of the day. He was going to take what he wanted, all the way. And what he wanted right now was to fuck his boss's muzzle! The dog pushed Will's head back so he could stand back up and begin driving his hips forward into Will's surprisingly obedient muzzle. He could feel the other dog's tongue nudging against the base of his cock, digging deep into his sheath.

With Will so occupied with his humiliating task Derrick slowly pulled out his phone, careful not to alert the other canine. Derrick grinned to himself as he unlocked his phone and opened the camera app. This was too good of an opportunity to pass up. As Will continued to pleasure him, Derrick positioned the phone , angled such that it captured the degrading scene playing out in front of him. He could already envision the look on Spencer's face when he saw this, and a shiver of excitement shot through him.

William, oblivious to Derrick's scheming, continued where he had left off. His tongue lapped at the base of Derrick's cock, teasingly flicking at the sensitive underside. It was a testament to his mild-mannered nature that he was able to steel himself and do this at all, let alone perform it well enough that moans of pleasure were escaping from Derrick's muzzle. But even as he submitted to this humiliation, William's mind was racing, formulating plans, and contingencies. He knew this wasn't over yet; in fact, it had only just begun. As long as Spencer held this over his head, William would be at his mercy. He could deny any of this had happened, tell the Doberman that Derrick had simply walked away.

As Derrick's moans grew louder, William knew he was nearing his breaking point. He redoubled his efforts, taking the shepherd's girth even deeper into his mouth, relishing the loss of control he experienced. His paw reached up to grip Derrick's balls, massaging them gently, stroking the tender skin behind them. Derrick let out a strangled whine as Will did so, his hips twitching involuntarily. There was a momentary look of panic in his eyes-- as if he'd let something slip-- but it was gone just as quickly as it appeared replaced by the smug grin.

"That's it... Just like that... Fuck." Derrick panted, bucking his hips into Will's muzzle in time with the lab's ministrations. After a few minutes, he was forcing the blunt tip of his cock against the back of his boss's throat and still the lab didn't seem to resist beyond his involuntary response to gag, which only felt more heavenly as that hot, tight throat closed around his dick like a vise, tempting him to choke Will each time. Derrick's pleasure mounted as he thrust into William's throat, relishing the power he now held over his mentor. The lab's paws kneaded Derrick's thighs, guiding the pace as he took the shepherd's length again and again. His eyes watered but he did not resist or pull away. Satisfied with his recording of William impaling himself on his cock Derrick pocketed his phone and focused on the amateur blowjob.

Through gritted teeth, Derrick managed to moan out, "W-Will... I'm, I'm g-going to cum!" He tried to pull out, but William's paws held him in place, guiding the shepherd's release that much closer. The lab abandoned any semblance of subtlety now, greedily sucking and massaging Derrick's cock with renewed vigor. With a growl Derrick pulled Will off his cock for the first time since they started. The lab looked up, confused, mouth hanging open, pre and spit dripping from his lolled tongue before glancing down to see where Derrick was looking. Between his legs, beneath his slacks, his cock was straining visibly against the fabric. Will glanced up in time to watch Derrick smirk toothily down at him, "Go ahead, whip it out. Let me see that cock Will." the shepherd ordered. The lab's face lit up a bright red beneath his fur before he reluctantly did so. The lab's cock wasn't as big as Derrick's own. Honestly, it wasn't much bigger than Derrick had been when he was just a pup. The shepherd nodded slightly with a smirk as he took in the sight of his mentor's cock. “Holy shit Will, how can you possibly satisfy your wife with that twig?"

William felt his cheeks burn even brighter at the insult, but he didn't have time to respond as Derrick roughly pinned his cock with his shoe and began firmly grinding it into the carpet. The pressure was almost too rough against the coarse carpet, but the way he ground the lab's cock under his shoe made William's back arch involuntarily. He knew he shouldn't be enjoying this, but his body wasn't listening to his brain anymore. His breathing hitched as Derrick continued to work his cock, feeling hot precum beading at the tip.

"That's right, Will, moan for me," Derrick growled, reveling in the power he held over his mentor. He couldn't help wondering how he ever looked up to the lab. "You like that don't you? You like being under someone else's control for a change?"

William couldn't deny the humiliation of the situation was somehow arousing, but deep down, his mind raced with ways to regain control. He forced himself to focus on how he could escape from the situation, but each grind send new sparks shooting down his aching length.

Suddenly Derrick moved his foot aside. He smirked as William inadvertently let out a little pant of need. “Go ahead, jerk that little lipstick you call a cock. Embrace your inner bitch." The shepherd smirked as he watched his boss begin to stroke himself uncomfortably before hilting his cock roughly into the lab's muzzle once more. The office filled with the wet, sloppy skull fucking along with the wet sound of his boss masturbating while offering it.

Unfortunately for Derrick, he couldn't resist his boss's muzzle for too much longer. After a few more minutes his thrusts became erratic. The shepherd grit his teeth as he freely fucked Will's muzzle and throat, his hips a blur as he jammed his groin into the lab's muzzle. Derrick yelled out as he came, bucking his hips forward one last time and emptying himself into the waiting warmth of William's mouth, shooting the first hot, thick rope of cum directly into that wet, pink orifice, splattering his seed across Will's throat before pulling his hips back from that suckling maw to shoot three more ropes of his cum into the lab's muzzle. White-hot pleasure surged through him like an electric current, surpassing anything he had ever experienced before. His knot began to swell and harden even more, popping right out of his sheathe like an angry red plug. William felt the sudden twitching and the flood of hot, thick semen filling his mouth. His eyes widened with shock as some of it leaked from the corners of his muzzle, painting his muzzle in the sticky mixture. Derrick moaned loudly in the older dog's office, tail wagging dominantly as he came harder than he ever had in his life. The sound of Will gulping his cum, choking slightly as he came in time with Derrick and splashing his cum onto the carpeted floor at his desk, was the icing on the blissful cake. The shepherd stood there, letting go of Will's head and sitting back on the desk as he heard Will lapping up the mess, dutifully cleaning up what he did from Derrick's spent, softening member. Derrick enjoyed the afterglow of his climax, burning this memory into his brain forever.

The way the sky slowly turned purple as the last of the sun vanished over the horizon. The heat of Will's breath blowing across his sheath as his cock retreated into it. The way the lab's breath came labored from the throat-fucking and the sticky cum lining it made Derrick shiver as he tucked his softening member and sheath back into his pants. The shepherd let out a long, heavy sigh of relief as the biggest goofy grin of his life spread across his muzzle. His eyes glazed over as he savored the view of Will on his knees, lapping up the shepherds still warm cum from his lips. His fantasy, one he'd been silently sitting on for almost a year, happened. He wasn't going to wake up and find that none of it was real. They were both here, this was real! All he had to do was take it, like Spencer said!

Derrick reached down, lovingly stroking the side of Will's head, "That was amazing, Will..." Derrick huffed, still catching his breath, "I'm really looking forward to seeing you here again tomorrow." He said, noting the slight shift in Will's expression, surprised perhaps? Apprehension?. Will eventually responded with a far less confident smile back up at the other canine. "Yes, of course, Derrick…" he said in that perfectly smooth voice of his, marred only very slightly by the scratches to his throat from a rough skull fucking moments ago. The shepherd gave him a hard look. “… sir" .

With that, Derrick pushed himself off the desk and forced his numb legs to carry him all the way back to his car. Now that he was alone, it was all he could do to not hyperventilate. His mind was still reeling from what had happened. With shaky paws he composed a message to Spencer, attaching the lewd pictures he captured of William sucking his cock along with the video.

"I can't believe it, Spence, I actually did it!" Derrick typed as he stared at himself in the rearview mirror, scarcely believing what had just transpired. A slow grin crept across his muzzle as he adjusted his pants, feeling the sticky remnants of his climax still dampening the front of his slacks. "I'm a fucking beast." He chuckled to himself.

His phone vibrated with a new message from Spencer. “I knew you could do it, man! I told you once you tasted a bit of that power, you'd be hooked! So, what's next? You gonna keep riding this high or are you going for more?"

Derrick smirked as he started the car. "Oh, I'm definitely going for more," he purred. "William may think that was a one-time thing, but he's sorely mistaken. I can taste it now, Spence... power... dominance... submission... I want more."

He took a minute once back inside his car to let the feeling return to the lower half of his body before driving home for the evening. The drive home was a blur as he replayed the events in his mind. He was going to celebrate by busting open that fancy $10 frozen pizza he splurged on the other day. Maybe even grab a little carton of chocolate milk at the nearby convenience store and watch one of his movies again. He was too focused on finally getting to have sex with the man he loved and lusted after since he started working to think about how a lot of things in his life would change once he got that job from Spencer.

Derrick woke up the next morning in a giddy state. He still couldn't believe that the previous afternoon's events really transpired. As usual he went through his morning routine, albeit with an extra pep in his step. The cute tabby barista tried to strike up conversation but Derrick was too eager to get to the office to pay her any heed. Virtually dashing to his car, Derrick hopped in and sped to the office.

Arriving a bit earlier than he usually did, he dropped his things by his cubicle before making his way over to Will's office. As luck would have it, the lab hadn't arrived yet. With a smile and some short small talk later Candice went ahead and let him into the office with their boss's coffee. Will arrived fifteen minutes later, looking much worse for wear.

Will shuffled into his office, dropping his briefcase on the floor with an unceremonious thud. He barely registered Derrick's presence as he collapsed into his desk chair and rubbed his temples. Neither of them made any mention of the previous evening's transgressions. Will because he was eager to move onward from the situation and Derrick because he was biding his time.

"Rough night?" Derrick asked, forcing a modicum of sympathy into his voice, setting the coffee down deliberately in front of Will.

Will grunted in response. "You could say that."

Derrick perched on the edge of Will's desk, gazing down at his mentor, with an almost predatory look. He was seeing Will in a new light. He took note of the ruffled fur, the off-center tie, the partially tucked shirt. His morning was not a smooth one. Will sighed, leaning back and closing his eyes. "Just relationship drama. Nothing I can't handle."

Derrick nodded, even though Will couldn't see him. He eagerly waited as as the lab reached for the coffee. The lab grasped the cup and took a large gulp. His eyes immediately shot open and he spat the mouthful back into the cup, grimacing in disgust. “Missing something right pup?" Derrick asked. “Ah yes. Cream. How could I have forgotten." The younger canine said with a smile. He stared hard into Will's eyes before he spreading his legs and nodding towards his groin. Just then the phone rang and Candace's voice came over the intercom. “Mr. Minsh? Mr. Bailey just called sir. He said there was something he needed to give you this morning? I told him you were in a mentorship meeting but he was insistent. He'll be here in thirty minutes."

William looked visibly shaken when he heard that Spencer was coming to the office. He pressed the call button with a shaky paw. “Th-thanks Candace. That will be all."

“Will it?" Derrick asked with a cocked eyebrow. The unasked question hung in the air for a long moment, before the lab broke the gaze. He hung his head in submission. William took a deep breath and composed himself before speaking.

"Derrick, I understand you may be feeling emboldened after yesterday, but this behavior is inappropriate. I care about you and want to see you succeed, but we need to have a professional mentor-mentee relationship."

He stood up and put a hand on Derrick's shoulder, never really being able to meet his young mentee's eyes. "You're still young with your whole career ahead of you. Don't jeopardize that over fleeting desires. There's so much potential in you, I'd hate to see you waste it."

“Nope. Try again." Derrick said matter of factly.

William's ears flattened against his head as he removed his hand from Derrick's shoulder, the rejection stinging more than he cared to admit. "Derrick, I—" he started, but the younger dog's icy glare silenced him.

"No, Will," Derrick said, emphasizing the newfound familiarity in the shortened name, "You gave me a taste of what your mouth could do, there's no going back." He lean forward, his face inches from William's. "So, why don't you go get your cream, pup?"

William's tail tucked between his legs, a sign of submission he hadn't exhibited since puppyhood. He couldn't deny the thrill he felt yesterday, but at the same time, he knew this new dynamic was wrong on so many levels.

"Oh, we both know you liked it," Derrick purred, reaching down to grope William through his trousers. Despite himself, the Labrador let out a small gasp at the contact. "Don't fight this, Will. I can make you feel so good..."

William trembled, hating how his body was responding. His resolve was weakening by the second as Derrick continued stroking him teasingly.

"Please, Derrick, we shouldn't..." William whimpered half-heartedly.

“Be a good dog. Go get your bone."

He didn't want to believe he was actually considering this, but the memory of Derrick's words and hands last night were still fresh in his mind. His cock twitched involuntarily as he pictured the scene playing out again.

"Will?" Derrick's voice carried. "The clock's ticking, pup."

William's ear's flattened against his head, his fur a mixture of embarrassment and arousal. With shaking paws he reached a paw over and fished out Derricks cock. William's heart raced as he wrapped his paw around Derrick's hardening shaft. The feeling of the warm, velvety sheath over the rigid length sent a shiver down his spine, both from humiliation and unwanted arousal. His cock twitched in his pants at the thought of what he was about to do. He took a deep breath, trying to steel himself for what was to come, and began to stroke the thick length.

Derrick moaned softly, closing his eyes and leaning back against his chair. "That's it, pup. Show me how much you missed my cock last night."

William's face burned brighter than a tomato as he pumped his fist up and down the length of Derrick's dick. He couldn't believe he was doing this, masturbating his intern in the office, but at the same time, he couldn't seem to stop. Derrick's low moans of pleasure only fueled his own arousal, making his already tight pants even more uncomfortable.

"Faster," Derrick growled, "Make me cum like the good little bitch you are"

Will worked his paw faster. Squeezing the slick length in his hand. The room was filled with Derrick's quiet grunts of pleasure as the lab jacked him. Every so often the older canine would glance over at the clock. Fifteen minutes had already passed and Derrick showed no signs of finishing. In an act of desperation Will opened his muzzle and engulfed Derricks cock down to the knot.

Derrick's eyes shot open, and he let out a low moan as Will engulfed his cock. The feeling of the warm, wet heat enveloping his sensitive head was almost too much to bear. "That's it, pup. Suck it like you mean it," he growled, grabbing fistfuls of Will's ears in ecstasy.

William gagged slightly, but he didn't stop. He knew he had to make this good or face the consequences. He also couldn't deny the sick sense of pleasure he was getting from pleasing Derrick like this. Embarrassment and arousal warred within him as the seconds ticked by.

"I'm cumming!" Derrick cried out, arching his back as his knot swelled even larger. William ripped his maw off the younger canine's cock and grabbed his open cup of coffee. Using a finger he peeled back the little bit of sheath keeping Derrick's cock from sticking fully out. With more ease than he was comfortable with he aimed the cock into his cup and rhythmically. The knot at Derrick's base swelled even further as he blasted shot after shot into Will's drink.

As Derrick's orgasm subsided, he looked down at the steaming cup of coffee, now adulterated with his seed. A smug grin crept onto his muzzle as he eyed William. "Well, looks like your coffee needed some cream after all," he quipped, earning a reluctant chuckle from the humiliated Labrador.

William's ear tips burned with embarrassment, but a part of him was oddly proud that he managed to please Derrick so well. He glanced at the clock and gasped. "Oh no, you have to go! Spencer will be here any minute!"

Derrick adjusted his trousers and zipped the fly nonchalantly. "Aren't you gonna have your drink? You worked so hard for it after all" He winked at William. Though he said it was a smile, the command was obvious to them both. The lab gave a wan smile before tipping the mixture of cum and lukewarm coffee into his maw.

Satisfied Derrick sauntered out of the office and back towards his desk. He took note of Spencer turning the corner and gave the Doberman a curt nod. The big dog gave him a wink before continuing towards Will's office.

As William frantically tried to compose himself and clean up the mess he'd made, he couldn't help but feel a twinge of anticipation and dread for Spencer's arrival. William scrambled to tidy up his office, shame and arousal still warring within him. He threw open the windows and sprayed some sanitizer to kill the smell of sweat and sex. The Doberman sauntered into the office, looking impeccable as always in his tailored suit. His eyes immediately fell on William.

"Morning, Willy," Spencer growled, placing a paw on the Lab's lower back. William shivered involuntarily at the contact. "Get my email about the quarterly meeting? I need to give you a deliverable" He spoke loud enough for Candace to hear before shutting the door and dropping to a whisper.

"Y-yes, of course," William stammered, cursing himself for letting Spencer fluster him so easily. William's face burned. He knew exactly who Spencer meant by that comment.

"Good. I know I can count on you." Spencer leaned in close, his hot breath tickling William's ear. He snaked his arms around the lab's waist. One paw slipped down the front of trousers. “Looks like someone's happy to see me."

William's face flushed a deep shade of crimson as Spencer's practiced paw squeezed his now-hardening genitals through his trousers. He knew it was wrong, but he couldn't deny the thrill that coursed through him as his cock twitched in response to Spencer's touch.

"S-Spencer, we can't do this here," he managed to whisper.

Spencer chuckled, his voice low and dangerous. "Oh, I know. But I just couldn't resist a little greeting for my favorite bitch." His paw gripped William's crotch tighter, sending a jolt of pleasure-pain through his body.

William felt uneasy as Spencer's large paw groped him in his office. Despite his weak protest, his traitorous body responded, his sheath moistening in arousal.

"That's it, be a good boy for me," Spencer purred as he massaged William's hardening length. The Labrador whimpered, hating how his body betrayed him. But he knew resistance was futile against the powerful Doberman.

Derrick idly tapped away at his keyboard while browsing his inbox. His mind lost in thought as he wondered what was it that Spencer needed William for this morning. Shrugging he muddled through the monotonous task of answer the emails that had piled up. Sometime later Spencer left with a spring in his step, but Derrick didn't think much of it.
