“Well,” he started, a hungry grin forming on his lips, his warm breath tickling Mastermind’s kiss-littered neck, “this isn’t about them, is it?” --- or, mastermind teases psyker one too many times and gets fucked silly three times.

“Th-There… there are people outside this door—”

Earlier, there weren’t, and Mastermind hadn’t minded then.

Then was when Mastermind had worked up the courage to play a drawn out game of teasing Psyker senseless all afternoon in the lounge room on one of the couches until he couldn’t take it anymore and enacted his revenge on the coy scientist by shoving him against the nearest surface and kissing him until his lips were swollen. Then was also when Mastermind was sure they were alone, Esper tugging Dissembler out on some shopping trip hours ago apparently, which was why he was feeling particularly bold with this plan.

But now?

“Psyker! Mastermind! We’re back! We even got the cake!” came the muffled voice of Esper on the other side of the door.

“Oh,” Dissembler’s curious voice began, “no response, perhaps they might be out too?”

Now there were people again, namely, their other counterpart-roommates that had returned, of-fucking-course. (And of the two, one of them was definitely more nosy.)

Hearing that seemed to spur Psyker into action, with practiced finesse, he hefted Mastermind up onto the desk, prying his legs apart even wider. “Well,” he started, a hungry grin forming on his lips, his warm breath tickling Mastermind’s kiss-littered neck, “this isn’t about them, is it?”

“Psyker—” A gasp cut his sentence short, feeling the thick head of his cock tease his exposed, wet, and slick hole. He shivered with the anticipation of being filled to the brim and yet, knowing Psyker wasn’t going to let him off the hook that easily, he whined with restrained desperation. “W-Well, it’s not. But… !”

“Getting shy on me because we have an audience?” Psyker cocked his head, beaming at him with a toothy grin.

Damn him, yes! Yes, he was… but even so, Mastermind’s hazy gaze traveled down the length of his exposed milky white stomach, to his legs still held apart by Psyker’s hands, hickey marked thighs quivering with anticipation. He didn’t need to look to feel how hard he still was, how his dick throbbed with need, how he could feel precum still gathering at the head from their earlier play. His chest rose and fell as he tried to calm his breathing, ignoring how hard his nipples were with arousal of the situation.

The thrill of being caught and heard sent a spike of heavy arousal straight to his core.

“Looks like down there doesn’t seem to mind so much.”

Mastermind’s denial only worked so well until Psyker voiced it against him. Unable to hide said excitement, he huffed. “G-Get on with it then!” Though Mastermind tried to hiss his order quietly the delivery ended up being an embarrassed whisper, unable to quite forget about the two on the other side of the door though it excited him all the same.

Properly resting Mastermind atop the desk, Psyker stepped closer, muffling a groan as he held Mastermind’s thighs. This close, he was able to tease at the puckered hole, still wet and puffy from being fingered earlier. Experimentally, he prodded two fingers in, pleased to see Mastermind could take that much without being bothered by the intrusion. Satisfied with his work, he settled closer and nudged his head to push past the ring of muscle. He slipped into the scientist’s mind numbing warmth thanks to the foreplay from earlier with a lack of resistance. Gathering his bearings, he inched further in with an experimental roll of his hips, head drooping lower and lower as he penetrated Mastermind even further.

For Mastermind, it was like a searing heat was spearing him open, parting his inviting, warm and slick walls. It was too much and not enough at the same time. He wanted Psyker to stop, gasping greedily for air as he sank deeper still; he wanted him to keep going, craving the need to be filled in a way only Psyker could.

“Shit, Mastermind,” Psyker gritted out, hovering over him when he finally bottomed out, finally balls deep.

He didn't care that he almost cracked his head back on the wall behind him somehow, too taken by Psyker finally filling him up as his head fell back further, consumed by the rush of sensations: the heady feeling of his cock, the insane amount of warmth both inside and above him, the feeling of completion. Beyond that though, Mastermind only really cared that Psyker was finally sheathed inside him and he was so—"H-hah, full…” Mastermind moaned again, rolling his hips, squirming atop the desk.

Connected like this, it was easy for Psyker to lean closer and swallow down Mastermind’s moans into a heated kiss, his tongue pressing demandingly along his own which encouraged Mastermind to moan against his lips even more.

When Psyker pulled away, with nothing but a thread of spit connecting them, Mastermind shivered, resisting a whimper as he felt how easily Psyker was pressed insistently against his prostate but had refused to move just yet. Really, it was beginning to drive him mad. Collecting his breath, he felt himself well adjusted now and murmured a bashful, “... you can move.”

He waited.

After a stretched pause of which nothing happened, eyes fluttered open to find his partner watching him rather heatedly instead. Indignant now, from waiting and from nothing happening still, Mastermind pouted. “Psyker, move already… !” And if he wouldn't, then well, Mastermind would take matters into his own hands. At this angle, it proved to be a bit of work, but he was determined until an abrupt, harsh slam of Psyker’s hips meeting his own hips harshly had him recoiling, back bowing and nearly screaming due to the unexpected but swift dig at his prostate.

The brawler tutted at him for his poor decision, then stilled again, “I'll move when I'm ready, besides, I'm enjoying you on my dick right now.” He replied crudely. His smirk only stretched wider as Mastermind's cheeks flamed bright red in response. “In fact, I think I like you just like this.”

Suddenly, Mastermind was regretting his incessant teasing from earlier. “You… ! You cannot be serious!”

“And what if I am?”

For a brief moment, Mastermind wanted nothing more than to summon Apocalypse to rain hell on him. But, well, that would not only do him no good, he might as well be announcing to the others that he was warming Psyker’s cock currently. Again, recalling the potential audience and the current cockwarming situation, Mastermind blushed beautifully.

As much as he liked this (though he refused to be honest about it), he'd be damned if this was all he got. He mustered his courage to challenge Psyker instead, “I thought you were going to… drive me crazy? Make me cum until I can't anymore, were your words.” Mastermind was deeply proud of himself for managing to not flush as he wiggled his hips to entice Psyker. He then used either calf hooked below his waist to jut Psyker’s hips forward a smidge, even if only to try and get him a little deeper than before. “You aren't doing a very good job of it.”

Bemused, Psyker hummed thoughtfully with a twinkle in his eye, as if he were considering his options. He leaned in as he replied, condescending, “I did say that, huh?”

The airy nonchalance almost made Mastermind snap. “Yes, so get to it, or I will!”

“Yea?” A lazy smirk crossed Psyker’s features as he drew in even closer, the gap between them but a breath apart, his eyes brightening as if an amusing thought had crossed his mind. Like a cat that got the cream, overly satisfied with himself, he said, “Help yourself then. If you want it so bad, then show me.”

Had Mastermind mentioned he was deeply regretful of teasing Psyker to hell and back yet? Still, this was nowhere as cruel as having his dick throbbing in his ass and not moving an inch for the past five minutes.

Fine then. If he wanted to be like that, he could give this cocky brawler a show… ! He'll make himself so appetizing, Psyker will be revving to finally fuck him. Though he dare not reply, instead he turned his efforts to pleasuring himself. He thought better about taking from Psyker like moments before, else he'd be met with another, singular but infuriating brutal thrust of his hips. So instead, Mastermind set on focusing on himself alone.

Ears slightly tinged red now, Mastermind reached to fondle his chest, the tip of his fingernail grazing a hardened nub, pulling a whimper from him. He did it again, and again, prodding and pinching at his nipple until it was perky and hard. Lost in his ramping arousal, Mastermind's other hand reached to give the neglected side of his chest the same treatment, biting down the smallest of whines that threatened to escape.

“Oh, wow…” Psyker murmured, intensely staring, eyes fixed on Mastermind and Mastermind alone. “You're sensitive there, huh…? They look so hard now when you keep touching them.”

“You don't have to narrate what I’m doing… !” He wanted to snap more at Psyker, telling him to stop looking and to stop being so embarrassing! However, besides that, he could detect the faint hint of interest, he noticed the slight hunger in his half-lidded eyes, could feel his dick twitch inside him, so he thought better of it. “I mean, I-I'm just doing what feels good to me…”

Psyker nodded, eyes dropping from his face now glued to his chest.

He took that as a non-verbal signal to keep going, so he did. Eventually, one hand wandered down, feeling that his own dick was being neglected. He took the head into his curled fingers and began to stroke himself generously. Soon enough, between toying with his hardening nipples, and his own twitching shaft, dick getting wetter, Mastermind could feel his climax building with each blissful rhythm of up and down up and down. Too deep in his own pleasure, Mastermind's hips shot up when he fisted his cock just right, his insides clenching on Psyker’s cock even more.

He had almost forgotten about that.

“Didn't m-mean to…” Mastermind peered at Psyker from heavy lidded eyes, chest rising and falling as he whined, “Just feels good.” Mastermind sighed with his own pleasure seeping deep within.

Across from him, Psyker grunted and leaned forward, nipping at Mastermind’s bitten up, swollen lips. He was more snug against Mastermind, cock slightly deeper than before but still he remained as he was. “Keep going,” Psyker urged, eyes falling down to Mastermind's swollen head, dribbling copious amounts of precum, he then licked his lips, “you're almost there, aren't you?”

“Mmhmm… !” Mastermind affirmed, his movements getting sloppy as he continued to jerk himself off with a chasing urgency, searching for the delicious pleasure from the friction of his hand. “Wanna’ come… so close,” Mastermind slurred his words with a half-moan, half-whine. He slowed the pace on his hand, feeling himself falling into his orgasm too quickly now. He slowed to a leisurely stroke as the precum dribbled from the slit of his wet head. The sensations drowned out everything once more until Mastermind drifted back and opened his eyes again (and when had he closed them, he wondered) to find Psyker’s intense gaze trained on him after all this time.

Psyker didn’t need to say anything, but Mastermind could feel the growing desperation practically rolling off of the brawler, radiating off of him. With the way his eyes carefully tracked each movement, each flick of his wrist, each twist and pinch under intense observation like a hawk watching its prey. Not to mention Psyker’s arms twitching with the effort of holding back from jumping him right then and there.

He was losing his composure and, Mastermind, drunk off his own pleasure, was able to still see this plainly on his schooled expressions.

Psyker was really holding back.

For some reason, that only served to turn him on more, drawing Mastermind back to his rapidly approaching climax. He exhaled a warm puff of air, realizing that the extra warmth was also from the closeness of Psyker, panting himself, who was even closer than earlier. He was so close, Psyker might as well kiss him. He wished he did, anyway, instead of being so stubborn.

Again, Mastermind’s ears turned a deeper shade of red with embarrassment but that didn’t stop him as he resumed his ministrations. Closing his eyes to drown out everything else, he felt the pleasure shoot all the way down from the tight knot forming in his stomach to his toes curling as his legs twitched and bent, the pace on his slippery dick now picking up speed. With a twist and rough pull of his abused nipple and a few more measured tugs while thumbing his slit, it didn’t take much for Mastermind to finally spill a generous streak of white over his heaving chest, further dirtying himself.

Mastermind, somewhat dazed, thought he might have heard Psyker hiss a curse. Before he could wrangle the mental capacity to ponder on that any longer, he gasped rather abruptly, “A-ah!? Knock it off,” and weakly, Mastermind reached up using the heel of his palm to push Psyker up and away, pawing at his face to keep him from getting any closer. He was cutting off his advance of kisses as well as the wiggle of his hips attempting to fit himself more between his legs so that his cock could slide even deeper. “I just came… I—”

“Sensitive, right?” Psyker asked knowingly, swallowing the hoarseness from his voice while ignoring Mastermind’s futile attempts to keep him at bay. Insistently, he placed kisses along his neck anyway. He then mercifully remained silent and motionless besides the affectionate peck here and there. A few moments passed and Psyker lifted his head from the crook of Mastermind’s neck to pat him gently. “You can go again, right?”

Go? Again?!

Firstly, again implied Psyker had even done anything to bring him to finish in the first place, which he hadn’t; Mastermind had been the one to do all the work! Secondly, what the hell was he thinking? He had just come, after all. But the only way Mastermind, tuckered out as he was, could communicate that was through a pointed glare, lips tugging down into a pout that weakened the effects of said glare. “I just finished… of course not.”

“I can,” Psyker replied, pressing another placating kiss to Mastermind’s jaw, as if that was supposed to encourage him and change his mind. “And I think you can too.”

“What—!” Some undignified noise like a squeal escaped him as Psyker adjusted him back on the desk. Mastermind realized Psyker was parting his legs to open wider once more so that he could reposition himself better back inside. Panicked, Mastermind raced to stop him but was too late as he cried out, “Now, just wait a—ahh!”

Without warning, Psyker slid back in, no longer stifling himself nor drowning out any of his sounds. He moaned freely at the feeling of Mastermind’s heat enveloping him eagerly anyway, caging him against the desk further to better nip at the inviting and yet to be blemished skin of his neck. “Sorry, but there’s no way I can sit back after that show of yours and do nothin’ about it,” Psyker nibbled along his ear, and with no shame tacked on, “you were really sexy, Mastermind…”

No matter how much Psyker whined apologetically, Mastermind wasn’t sure if it was his risque choice of words and attempt at a compliment or the overstimulation of being fucked post-orgasm that was driving him mad. “Psyker—!” He finally had what he wanted, exactly how he wanted him but now it was just too much. Beyond the mind numbing pleasure building, the raw nerves of his prostate being abused started to border pain. Maddingly, Mastermind didn’t try to resist much.

Psyker's speed seemed to be picking up now that he found his rhythm, the drag of his hips aiming to be less precise and more about how fast he could ram himself into Mastermind’s soft, welcoming insides. “God, you're still squeezing me so tight—”

A wail escaped Mastermind’s throat as he threw his head back again, a sharp stab aiming too perfectly against those oversensitive, twice abused bundle of nerves. “Ohmygod, Psyk—!” The pain of overstimulation was blurring now, mixing into a dizzying cocktail of pleasure that left the dick drunk scientist vaguely aware that he was oh so hard now and, despite his body protesting otherwise, wanted to come again.

Ignorant of his inner turmoil, Psyker threw all of his weight onto him, thrusts turning erratic as he cursed under his breath, praising Mastermind while warning him how close he was.

Dazed out of his mind, Mastermind preened for the attention, and as his jaw fell slack, his mouth parted for a breathy gasp, choked off by a whimper. Between the obscene slapping sounds of skin against skin, and the wetness of the telltale sign Psyker was nearing his finish, Mastermind found himself coming undone once more. A moan torn from his throat that trembled with a shake of his body as this sudden climax blindsided him.

With the way Mastermind’s ass clung so greedily to his dick, pulsing and sucking him further in, Psyker truly wasn't far behind. He reached his completion, joining Mastermind as he came deep inside, claiming that part of Mastermind all for himself. His hips jerked as he shook off the crashing waves of his intense orgasm threatening to engulf him. Then, when he found a little more energy, he drove his hips a little deeper as if to ensure his cum wouldn't spill, moving in little circles as he stirred up Mastermind’s overstuffed hole. “You’re mine,” Psyker mumbled, the possessiveness blatant coupled with the way he nipped at his ear again.

Wordlessly, Mastermind mouthed Psyker’s name with as much energy as he could muster, whimpering at the mess between the two of them, as well as the feeling of every nerve in his body alight with a throbbing, white-hot pleasure that made him feel so very far away, almost as if he were out of body. Gradually, minutes later, he drifted back with some semblance of his consciousness and peeled open his eyes, meeting Psyker’s infatuated, lovesick look. If he had the energy, he would have shooed him away, but he didn't. (Rather, if he’d had the energy, Mastermind would have kissed this fool of a man that he was equally as foolishly smitten for.)

Without a word exchanged between them still, Psyker reached to cup Mastermind’s cheek, a tender little motion as his thumb soothingly ran along his skin, both as a gesture of praise and a token of his affections.

Mastermind melted into the love of his tender gesture.

A smile danced its way onto Psyker’s features, the corners of his lips turning up as he took in the sight of this dazed, yet content Mastermind before him. “Mmm,” finally, Psyker broke the silence, “still with me there? Don’t drift off yet.”

Somewhat delayed in response, Mastermind nodded slowly, and then keened softly under the sudden additional affection. He nuzzled against his palm sweetly, sedated and sated.

Psyker laughed so softly, so fondly.

When Psyker pulled back, or, well tried to, Mastermind locked his legs around his hips, dragging his other half demandingly back to him, hip to hip. A gesture that clearly said you aren't going anywhere.

Lowly, Psyker hummed and then asked, “Don't ya want me to get us cleaned up?”

Mastermind gave another of his pointed looks, saying nothing else.

Nervously, Psyker avoided the scrutiny of that intense gaze turned on him, and chuckled. “What? What is it?”

Insistently, he tugged Psyker closer again, their hips connecting, and his dick, nudging Mastermind's cum-filled insides.

“H-hey, cut it out—”

“You're not done yet, are you, Psyk?” Mastermind teased, smiling coyly up at the brawler who was now caught red-handed. “You're getting hard again, aren’t you? Can feel you—” And to prove his point, he canted his hips upward again. A curious but pleased little sound escaped him when he found his assumptions to be correct, that Psyker’s slowly hardening dick twitched to life deep inside of him with rising interest. “Admit it, you want this again as much as I do.”

With everything laid bare, there was no reason to hide anything then if Mastermind saw through him, or, well, felt how obvious he was. Groaning, Psyker flopped his weight on Mastermind with exaggeration and whined loudly, possibly out of embarrassment. “You're gonna be the end of me… I swear!”

Again, Mastermind wiggled his hips, “Until I can't come anymore, right?” Breathlessly, Mastermind laughed, wondering if Psyker was the one regretting things now. Psyker shouldn't have allowed Mastermind to catch his breath; between the small respite offered and loving affection, Mastermind felt vigored once more, if not a little sore but that mattered not.

… and maybe he had wanted to take care of Psyker's needs now too.

“There… ain't no bed, ya know.”

As if that paltry excuse would deter Mastermind, especially after getting fucked twice on a desk of all things. “Not a problem, use those wonderful muscles of yours to get us both over to that chair. It’s more than sufficient.” And when Psyker seemed confused, Mastermind huffed with a speck of bashfulness then clarified, “I wish to ride you.”

Psyker did not need to be told twice.

With their new setting, Psyker seated comfortably, Mastermind with wobbly, sticky legs, hovered in the other's lap. Though he'd caught his breath, it seems he miscalculated that the rest of his body hadn't quite caught up yet. He felt like a baby deer with clumsy limbs. No matter, he just needed to seat himself…

“You… Ya really don't have to, Mastermind…” Despite the protest, Psyker didn't move to stop him, an eager hand running along his spine appreciatively and then trickling down to finally rest at his waist.

“Feeling bad about earlier?”

“Maybe…”

“Good, now be quiet already and let me just take care of you.” When Psyker made a face of protest, Mastermind rolled his eyes affectionately, and nudged the brawler down until his back hit the chair. “I enjoyed myself earlier too, so hush. Now, just let me—” His words tapered off as he pressed his ass back on Psyker’s now throbbing and still wet head. Mastermind ignored the cum leaking from his own ass. Though thanks to his walls still being coated with the brawler’s cum, he found the sliding back on Psyker came without a struggle.

Psyker hissed due to the rather abrupt and enveloping pleasure, his eyes screwing shut, unable to watch the demonstration of Mastermind taking him to the hilt once more in one fell swoop. He was not immune to the hot man above him and would surely come from that alone.

“Fuck! Mastermind, I—”

Though he was winded from his ass swallowing Psyker’s cock in one go, Mastermind did his best to scold him, “Might I remind you that these walls aren’t sound proof?” He did his best to smile sweetly down at Psyker, having fun with the tables being turned now.

Though… his reminder only served to make Psyker throb inside Mastermind harder instead of dissuading him to lower his voice.

Feeling encouraged by Psyker’s vocal displays of desire, Mastermind set to work. He gathered his strength to lift himself about halfway off his dick and then let gravity take over to slam him back down. He repeated this motion a few more times before he grew frustrated, a displeased little noise that he huffed Psyker’s way.

“Hey, this… this wasn’t my idea!” Psyker rebutted before Mastermind could dump the blame on him, brows knitted with worry.

“I can… can do it!” Mastermind insisted through a huff, already breathless from the effort. So he tried again, and again until he could get himself a steady albeit slow rhythm of bouncing on top of Psyker’s lap. Once the pace was set, Mastermind was able to lower his gaze to regard Psyker, much like how the other man did the same to him prior and what he saw made him suck in a breath of air.

Psyker had his head tilted back against the chair’s headrest. Teeth gritted and entirely motionless aside from the wandering hands still at Mastermind's waist, which would wander up and down before settling on a spot. A light flush was creeping its way onto his cheeks, with his neck already flushed red, and when he lifted his head just enough to peer up at the magnificent sight of Mastermind atop him, riding him as best as he could, he uttered a low curse and bit his lip hard.

“P-Psyk… !” The other man’s reactions flipped a switch for him and he whimpered with a newfound desire… to do something, anything for the man below him. To make this better. To drive him crazy. “Psyk, help me out?” And with an equally red face, tilted his head bashfully as he wiggled his hips for his suggestion.

At first, too lust consumed, Psyker was at a loss. He blinked a few times and, through silent communication, came to understand what it was that Mastermind had wanted. Those same hands rubbed along Mastermind’s thin waist, fingers grazing the skin there playfully. With a lick of his lips and a fire in his eyes, he answered back, “Gotcha’.”

Satisfied with their plan, Mastermind nodded happily to his beloved and put their ideas into motion. He lifted his hips and he felt how Psyker followed up, his hands dropped to his hips and then plunged him back down. “Ah—!” A little faster than he anticipated but just as good if not better than what he was doing by himself. Again, Mastermind raised off of his dick to the tip and Psyker pulled him back to the hilt. This give and take motion served them both better, and it was clear on their blissed out faces that it felt good to them both. Eventually, Mastermind, used to this, decided to set a faster pace, rising up only half-way now and urging Psyker to slam him down even quicker.

Psyker complied easily.

“So—good!”

“Hah…” Psyker nudged Mastermind closer so that he could brush his lips along that tantalizing show of skin near his collarbone. “You. Drive. Me. So crazy… !” Each word was punctuated with a snap of his hips meeting Mastermind. The last thrust, however, he grinded deep, deep against that spot that he knew would make Mastermind lose it.

Mastermind moaned incoherent sounds, failing to form a single word as he writhed atop Psyker’s lap. He gasped and screamed wildly, his shrill cries going an octave higher each time Psyker dug even deeper into that spot. “Oh—fuck, please… pleasepleaseplease!” He unceremoniously fell forward, both hands scrambling for purchase and finding himself gripping Psyker’s shoulders tightly, nails digging in.

More curses tumbled from Psyker as the temptation to sink his teeth into Mastermind’s neck was right there. So, he did.

Yet another wail escaped Mastermind, his back arching beautifully this time. It was as if he was at war of whether to smash himself as close to Psyker as possible, closing all distance or to run from this decadent pleasure coursing through his veins, overwhelming his senses and setting his nerves alight. It was addicting and Mastermind felt himself fading from barely coherent to his head going completely empty. At this rate, he wouldn’t last for long. With what little sense he had left, one hand swooped down to fist his dick with a vigor unlike anything. All he could focus on was the basest desire of driving himself to his end, to finish and make a mess on Psyker’s chest. The mental image alone of ruining Psyker’s rumpled shirt almost made him lose it right then and there. “Please, harder, need you harder…!”

And who was Psyker to deny his pleading lover atop him, making so many beautiful sounds just for him? He planted his feet to get his bearings and brutally fucked up into Mastermind as hard as he could without abandon. With his hands still on Mastermind’s hips, he was able to guide the younger male to bounce on his dick again and again. Grunting in between calling for Mastermind, Psyker’s breath became labored. Fortunately for him, he still had some of his wits about him enough to warn the whimpering mess above him, “Can I… inside Mastermind?” Without waiting for his answer, his lips busied themselves, latching on his neck, then southwards to a bite and suck a hickey into his collarbone, and then finally landing on his perky nipples where he took one one into his mouth and sucked hard.

“Yes, y-yes… oh my god! Yesyes—!” It was unclear if Mastermind was giving his consent specifically for Psyker’s request but the enthusiasm was there and he’d finally, finally reached his orgasm at the tail end of his last blissed out chanting. Fucked out of his mind and ruined, Mastermind came one final time, hard, hand working furiously as he jerked himself through the motions, spurting cum against his stomach and Psyker’s wrinkled up shirt.

Seeing Mastermind come so undone before him like this, Psyker was crazed, carnal in nature like some rabid beast, as he drilled harder and faster, seeking to join his spent partner. With a few more wild, relentless thrusts, he was balls deep, flooding Mastermind’s walls once again. He shuddered with a few more aborted rolls of his hips. And despite his softening cock plugging up Mastermind’s ass still, Psyker was able to feel how the other was too full of him from earlier. Streaks of cum began to leak slowly from his ass, dribbling around his cock. Panting lightly, Psyker opened his eyes and found Mastermind slumped forward, all dead weight and just as spent, hand unmoving on his dick.

“Mastermind?”

No response.

To pull a reaction and to be a little shit, Psyker reached for whichever hand Mastermind still had on his softening cock and gave a nice pump of his own, laughing softly when that finally stirred the exhausted scientist into mewling weakly in disagreement.

Shaking his head, he whined in a fashion that could only be assumed as a silent no more.

Which Psyker understood perfectly. He tried to nudge Mastermind a little upright to hold him better. When Mastermind got like this, it was near impossible to clean or move right away, so he made himself comfortable (as he could be, anyway, with the mess still between them and dripping from Mastermind’s cheeks onto his thighs). Idly, he played with Mastermind’s sweat damp hair and placed a few careful pecks to his cheek. He waited patiently until Mastermind was able to find clarity to speak again.

“If you overstimulate me…” Mastermind struggled, finally finding the breath to speak, “like this again, I’ll—”

Psyker interrupted Mastermind with a deep kiss, then pulled back with a smirk, “You liked it.”

Mastermind immediately buried his face into Psyker’s neck, the heat rising from his cheek, but not uttering a single word to deny what Psyker said otherwise.

Psyker chuckled fondly once more.

-----

Later that day, Dissembler and Mastermind sat among the couch together, trading their notes between one another in silence as they analyzed their findings and the numbers and such. Both had papers and notes in hand, and would only look up to the stare at the shared screen floating between them now and then.

That was how Psyker found the pair, deep in thought and running calculations. Knowing better than to disturb them, as it was near impossible to catch either of their attention when they got like this, Psyker simply strolled in. He made a quick stop behind the couch to lean down and kiss the top of Mastermind’s head sweetly, then another suggestive kiss placed behind his ear. With that accomplished, he leisurely left the way he came, hands in his pockets.

There was nothing but the usual silence.

And then, it was Dissembler that did the unusual and broke the silence. “... you and Psyker … you both did not leave the house today, am I correct?”

The way Dissembler struggled to form the words made Mastermind’s head shoot up from having his face buried deep in the notes only to reveal how his face was already red prior to his question. “Not… um, not exactly. Why do you ask, Dissembler?”

Again, Dissembler fumbled with his words. It was as if he too was trying to construct each sentence very carefully. A hand flew up to either side of his cheek, cupping it, but it did little to hide the red staining his own face now too. “No particular reason… but, Esper had mentioned you two were… preoccupied—”

“We weren’t doing anything!” Mastermind blurted out abruptly which of course only made him look more guilty.

Upon realizing this, they cranked their heads slowly in each other’s direction, blinking a few times until their faces mirrored one another’s—two brilliant, matching shades of red.

Well! Now Mastermind had no chance of hiding anything. (Though, was there anything to hide when it was as he thought? Esper, the ever nosy, ever devious bastard that he was…)

Dissembler said nothing more, curling into his side to further hide his face.

Mastermind whined to himself, shoving his palms into his face as he sank further into the couch, wishing the damned furniture would just swallow him whole.
