Ten Minutes

Summary:

A certain Salvonian grenadier loves to live on the edge, and Caustic is inevitably pulled along to join him.

Notes:

Hey everyone!!

First things first, this fic was inspired by this LOVELY sketch by @nsfwKaru on Twitter!!! She’s been giving everybody such amazing Caustic/Fuse content (and Apex in general!) so be sure to give love to their art and follow her!

On another note, this isn’t the normal caliber I go for in my writing. However, I’ve really been trying to get better at writing quickly, so this is a one night creation. Also, this is yet another example of the sexy people in the Caustic Simp server egging me on, so thank you to them for the motivation as well!

Anyways, I hope you all enjoy! And again, please go give some love to Karu and her amazing work!

“C’mon, darl. Loosen up.”

“No. I need to finish this.”

“Give yourself a break.”

“Walter, I don’t have the time—“

Caustic’s words died in his throat as his partner pressed a palm greedily against his groin. The strong fingers kneaded into the thick fabric of his pants, and he released a shaky breath.

“You deserve it...workin’ so hard all the bloody time.” Fuse whispered smoothly into the reddened shell of his ear, and Caustic shivered at the warm breath that ghosted upon it. He could feel Fitzroy’s weight against him, leaning over his shoulder, and he settled back into his chair with a resigned breath.

“You have ten minutes.” The chemist spoke suddenly, and Fuse smiled in response.

“Good thing I can get you off in five then, yeah?” The Salvonian retorted with audible humor, and he didn’t hesitate to round the office chair and drop to his knees. He scuttled forward until he was between the younger man’s muscular thighs—half underneath the large desk he sat at—and he made quick work of the fastenings of his pants. Caustic sighed as the demolitions expert freed his length from its confines, snickering under his breath as the Salvonian wolf whistled at the sight.

“You got hard quicker than water in the freezer.” Fitzroy bantered with humor, and he didn’t hesitate to wrap his good hand around the other’s semi. Caustic sighed heavily at the feeling, releasing tension of the day’s failed experiments and rushed miscalculations. He let his head fall back against the large desk chair he sat in, eyes closing to fully focus on what the other had to offer.

“You look gorgeous with your cheeks right and red like that.” Fuse pointed out with adoration, letting a thumb slip over the head of the other’s dick as he spoke.

“Eight minutes.” Came Caustic’s cool response, his voice belying absolutely nothing.

Fuse chuckled heartily before leaning forward and licking slowly up the length of the larger man’s erection. The thick cock twitched in his hand, and he hummed in confidence as the larger man exhaled sharply above him. The Salvonian was talented in his ministrations, and Caustic was grateful that he seemed to be moving along at a decent pace. All too often the older man would push his buttons and tease him, drawing the moment out for as long as humanly possible. When Walter grabbed the base of his cock and tapped the heavy length repeatedly against his outstretched tongue—a purposefully whorish action—he couldn’t help but to moan softly.

“That’s what I like to hear.” Fuse spoke from beneath him with an obviously humored voice, pulling away to spill the completely unnecessary words.

“Seven.” Caustic snapped back, reaching a hand down to coil it warningly in the smaller man’s hair. Fuse relented and took his cock into his mouth then, and Nox settled further into his chair as he enjoyed the warm wetness around him. Walter’s tongue lavishly curled around the flushed head of his erection, saliva mixing with his precum as the Salvonian pressed his tongue along the prominent vein on the underside. Caustic gently sifted through the graying hair between his gloved fingers, noting perceptibly that the other’s eyes were now closed with focus. He watched intently as Walter pleased him, his good hand wrapped tightly around the very base of his cock and the other palming at himself through his pants. Caustic once more let his head fall back and his eyes slip closed, nostrils flaring as he enjoyed the arousal that tingled in his lower abdomen. The older man pressed further down, taking him completely to the root without hesitation. He swallowed around the thick girth in his mouth, just the way Alexander liked it, and the larger man emitted a rough groan in response. Caustic glanced to the clock mounted on the wall across the room, and thoughts of his research immediately nagged at him. However, he forced himself to ignore them just for the next few minutes, his fingers gripping the armrests of the chair tighter as Walter intensified his motions. He could feel his peak steadily approaching, only spurred on by the Salvonian’s lewd, salacious sounds of enjoyment that vibrated against his cock. The muscles in his abdomen convulsed for a moment, and his lips parted to spill a low moan as he readied himself. He squeezed his eyes tight, and suddenly—

“Good evenin’, Dr. Caustic!”

Nox immediately scrambled up at the sound of the door opening and a friendly voice echoing across his study, his eyes meeting with those of Mary Somers. He hurriedly slid the chair closer to his desk—it’s wheels screeching horridly against the floor—thus forcing Walter to retreat further underneath the sturdy piece of furniture. He tried to school his expression in a moment of panic, but there was no steely expression strong enough to hide the heavy blush that crept onto his cheeks and ears. He waited silently, unsure of what exactly she had seen. However, much to his relief, it didn’t appear to be much.

“Door was unlocked, figured I’d stop by to see how yer doing!” She explained with a bubbly, energetic tone, and Nox held his breath as she came closer to him. Fucking Fitzroy, never locking the door like he told him to! Horizon paused at the other side of the desk, bracing one hand upon the edge of the wooden surface and reaching the other out to offer a stack of papers she was holding.

“Nat wanted me tae give you these! Said she wanted yer opinion on her newest heat regulator.” She spoke happily, the corner of her eyes crinkling as she smiled wide. Caustic reached out to take them from her, but the feeling of a warm hand wrapping around his now aching erection made his hand stutter awkwardly in the air. She looked at him strangely, eyes narrowed and head cocked to the side at that, and his heart skipped a beat.

“Are you feelin’ ok, dearie?” She asked thoughtfully, watching him with curiosity.

“I’m fine, thank you.” Caustic answered quickly, and the words came out much harsher than he meant them to. He reached out and snatched the papers, and under the desk he sharply kicked his heel into, what he assumed, was Walter’s side. However, in return the older man tightened his grip around him, and Caustic swallowed heavily in response.

“Anything exciting going on in this lovely little lab?” Horizon asked politely, thus dashing any hope Caustic had that this was going to be a short conversation. He adjusted the safety goggles he wore, futilely hoping that they would cover the blush burning across his pale face.

“Not particularly.” He answered curtly, trying his best to keep his voice level despite the fact that Walter was now stroking him off beneath the goddamn desk! He struggled to keep his eyes open, his nostrils flaring as he released what he hoped was a discreet exhale. Thankfully, Horizon was long used to his relatively weak conversational skills, and she continued it without pause.

“Tonight is a full eclipse of both of Solace’s beautiful moons!” She informed him, and he was absolutely horrified as she continued to talk. He normally didn't mind her presence—a preferable second to Miss Paquette. But given his current...predicament, her penchant to ramble was basically a death sentence. “Alteros will appear blue, while Astrinza will be reflectin’ orange light!”

Caustic liked to believe he was a man with fantastic self control and reserve. However, no amount of self discipline could have kept him from jolting in his seat as Walter took him into his mouth. He blinked rapidly at the sudden slickness around his cock, his breath hitching in his throat. He tried to maintain eye contact as Dr. Somers spoke, and he immediately attempted to pull his legs together. However, Fuse’s hands planted themselves firmly on his inner thighs and forced them apart. The Salvonian began to bob his head with well practiced expertise, and Caustic coughed loudly into his arm to muffle the groan that threatened to break free from his throat.

“Are you sure yer feelin’ fine, Doctor?” Horizon suddenly pulled his attention back, and he was met with an expression of concern marring her features. “Yer lookin’ right flushed.”

“Yes, just a bit under the weather.” Caustic choked out from behind gritted teeth, reaching out to grab the papers Horizon had brought in an attempt to distract himself. He sunk back further into the chair and used the papers to cover his face for a moment, giving himself an opportunity to glance down discreetly to his lap. The sight that greeted him was astoundingly arousing, and he immediately regretted his decision. Walter’s eye was already upon his own, and it was narrowed with very obvious amusement. He pulled the larger man’s cock from his mouth, instead mouthing along the sensitive ridge of the head with a devious grin. Nox forced his eyes away, instead glancing at the papers in his left hand. He stared blankly at the mess of words upon it, his blurry vision not allowing him to comprehend a single sentence. The corner of his mouth twitched upwards as Walter deepthroated him once more, and he brought his right hand up to cover any micro expressions he made. He glanced back up to Horizon with as much focus as he could muster, ignoring the buzzing in his head and the even more insistent simmering arousal in his gut.

“—and the rotational axis of Psamathe is only slightly different, but nonetheless noticeable.”

Caustic pulled himself to the present, realizing he hadn’t heard a single word of what she had been explaining. He nodded quickly in mock understanding, and the muscles in his abdomen twitched as Walter suddenly grabbed hold of his balls.

“And what’s this little beauty?” Horizon questioned as she plucked a test tube from the rack on his desk, and he was barely able to prevent the annoyed groan his brain insisted he release. He was quickly growing frustrated, wanting her to leave, wanting to finally get off...wanting to wring Walter’s fucking neck!

“Merely an inert sample.” He quickly spat out, not currently possessing the mental wherewithal to explain the complexities of his newly tailored compounds. He felt a weight against his groin, and he realized that Walter had rested his head upon his lap as he lazily sucked his cock. The Salvonian’s lips tightly encircled the head, and the feeling of his dexterous tongue pressing firmly against the slit made Nox cry out against his will. The small, growled sound almost made Horizon drop the tube as she went to set it back in its rack, clearly surprised by the sound. Caustic immediately covered it with rough coughs, and this was one of the rare instances in which they were faked.

“Are you gonnae be sick?” Horizon asked with audible concern, and she took a step as if she was about to come to the other side of the desk. Caustic immediately threw a hand out to stop her, wincing mentally as she stepped back in surprise.

“I’m fine, but don’t approach me.” The chemist assured her, although the gritty, breathy nature of his voice most likely did little to convince her. “I wouldn’t want you to contract anything, lest I turn out to be sick.”

Horizon looked at him oddly, and he squinted his eyes in a desperate attempt to clear the pleasure induced blur from them. Walter worked voraciously beneath him, tongue, lips, and teeth bringing him ever closer to his peak. Caustic forced an awkward smile to his face, one hand casually dropping under the desk to dig his fingers warningly into the muscle of Walter’s shoulder.

“Thank you for bringing these by.” The chemist spoke earnestly as he motioned towards the papers, and he hoped she wouldn’t be able to pick up on how quickly he was trying to get her out. “I will review them within the week.”

“I’ll leave you to it then.” Horizon answered with a somewhat muted voice, and it was obvious she was confused by the older man’s off behavior. “Dinnae work yourself too hard! Get some rest.”

“I assure you, I will.” Caustic struggled to speak calmly, Walter very purposefully increasing his efforts between his legs. He felt his pleasure quickly cresting into familiar peaks, and his fingers tightened their bruising hold against the Salvonian’s shoulder. “Thank you, Dr. Somers.”

“Anytime, dearie!” The kind astrophysicist spoke as she finally turned to leave the room. She waved over her shoulder, and the door closed with a pneumatic hiss behind her. Without a moment’s hesitation, Caustic shifted to firmly reprimand the man between his legs. However, Walter saw it coming, and he dragged Caustic to his climax with careless ease. All it took was the faintest scrape of a tooth, just the threat of pain and control, and Alexander broke. The larger man buckled forward as he came, moaning loudly with his head bowed over his desk as his hips thrusted up into the other’s mouth and throat. Fuse sucked him roughly through his orgasm, and his cock throbbed in time with his heartbeat as he spilled into the older man’s mouth. Caustic’s chest heaved beneath his white lab coat, and the desk rattled as his knee jolted out to the side and bumped into it. Walter took everything without complaint, and, in fact, he moaned languidly around Nox’s pulsing length as his spend filled his mouth. Once he had regained control over his body, Caustic waited for the other to swallow, bracing himself for the wave of oversensitivity that would surely make his muscles jolt. However, it didn’t come. The chemist looked down with confusion, only to gasp brokenly as Walter once again took his length deep into his throat. He began to slowly pull off, and, once he’d reached the head, opened his lips with an amused laugh. Alexander’s cum spilled down the length of his cock, dripping from Walter’s mouth and down to his groin. Fuse made an utter mess of him, and Caustic sighed in frustrated defeat, slumping exhaustedly into his chair. After a moment spent catching his breath, the chemist shifted his legs, and he cringed at the filthy feeling of the now cold wetness against him. Walter moved beneath the desk, but the larger man’s legs immediately wrapped around him.

“Clean up your mess.” Caustic ordered firmly, smirking playfully at the annoyed glare Fitzroy shot him. He could see the gears turning in his head—contemplating if he should obey or not.

“Sorry, your ten minutes are up.” Fuse eventually answered with a coy smile, rolling the chair back and expertly slinking out from between the other’s legs. He slipped a hand into his own pants, adjusting his very noticeable erection, before casually strolling towards the exit.

“If you don’t lock the door next time, I’m revoking your permission to be in here.” Caustic stated firmly, reaching to the shelf on his right to grab something to clean himself off with. After he deemed it sufficient, he tucked his length back into his pants and redid them, sighing as he sat bonelessly in his chair and glanced to the older man.

“You wouldn't dream of it, darl.”
