The Chief’s fingers dug into Calloway’s shoulder, blunt nails leaving crescent-shaped indents that would fade within minutes. Steam curled around them, thick enough to obscure everything but the heat of Calloway’s palm and the relentless pressure of his strokes. The Chief’s breath came in ragged bursts, his hips jerking erratically against Calloway’s grip. "Fuck —" he choked out, head thudding back against the rock. "Goddamn —"
Calloway’s mouth found the Chief’s pulse point, teeth scraping skin in a way that made the older man shudder. His thumb circled the head of the Chief’s cock with clinical precision, each rotation calculated to draw out the tension coiled in the Chief’s thighs. The Chief groaned, fingers twisting in Calloway’s hair hard enough to hurt if pain were allowed here. "You’re — ah — you’re a fucking menace," he gritted out, voice cracking.
The Chief's thighs trembled, his free hand scrabbling against the smooth rock for purchase as Calloway's thumb pressed harder — not cruel, just insistent. "Jesus —" The word shattered into a groan when Calloway's tongue traced the shell of his ear, hot and deliberate. The Chief's grip on Calloway's shoulder tightened convulsively. "Gonna make me —" His voice cracked, hips stuttering forward as his orgasm ripped through him with a force that left him gasping, forehead pressed against Calloway's collarbone.
Calloway's hand gentled, but didn't stop — drawing out the aftershocks until the Chief swore and batted his wrist away weakly. Steam curled between them, clinging to the Chief's lashes as he blinked up at Calloway, chest heaving. "Goddamn," he rasped, thumb brushing the doctor's lower lip where it was slightly swollen from kissing. "You're terrifying."
Calloway exhaled slowly through his nose, his thumb still idly tracing the Chief's hipbone where he'd collapsed against the rock. The older man's pulse thrummed under his fingertips, fast but steadying. "Terrifying's subjective," he murmured, watching the way the Chief's chest rose and fell with each ragged breath.
The Chief chuckled, dragging a hand over his face before letting it drop back into the water with a splash. "Says the guy who just dissected me like a goddamn lab rat." His voice was rough, but his fingers curled around Calloway's wrist with surprising gentleness, thumb brushing the delicate bones there. "You ever gonna let go, doc?"
Calloway's fingers flexed against the Chief's hipbone, the barest hint of hesitation before he withdrew, water dripping from his fingertips. The Chief watched him, eyes dark with something warmer than amusement, his breath still uneven against the humid air. Steam curled between them, obscuring the sharp line of Calloway's jaw as he straightened, his expression shifting back toward that unreadable calm — but his pupils were still blown wide, his pulse visible at his throat.
The Chief grinned, lazy and satisfied, and reached out to catch a droplet sliding down Calloway's collarbone with his thumb. "You gonna leave me hanging, doc?" His voice was gravel, worn smooth at the edges. His other hand trailed down Calloway's flank, fingers splaying over the tense muscle there. "Seems unfair."
Calloway exhaled sharply through his nose, the sound barely audible over the grotto's distant murmurs. The Chief's fingers traced his ribs with deliberate intent, pausing at a jagged scar along his flank — old, faded, but unmistakably surgical. "You gonna tell me where this came from?" the Chief murmured, thumb pressing lightly into the tissue.
"Field extraction." Calloway's voice was flat, but his abdomen tensed under the Chief's touch. "Mogadishu."
The Chief's fingers stilled on the scar. For a heartbeat, the grotto's ambient sounds faded — just steam curling between them, just Calloway's steady breathing despite the tension in his jaw. The Chief exhaled slowly, thumb smoothing over the raised tissue once more before sliding lower, past the dip of Calloway's waist. "Guess we're both full of surprises," he muttered, voice rougher than before. His palm settled on Calloway's thigh, fingers kneading the dense muscle there with deliberate pressure. "Clock's still ticking, doc."
Calloway's breath hitched before he caught the Chief's wrist, stopping his progress. Steam clung to their skin where their bodies nearly touched, water lapping at their waists in slow, heated waves. "Hypothesis," Calloway murmured, leaning in until his lips brushed the shell of the Chief's ear. "You talk to avoid listening."
The Chief laughed — a low, breathless sound that vibrated against Calloway’s shoulder where his forehead rested. His fingers tightened around Calloway’s wrist, not pulling, just holding. "Maybe," he admitted, tilting his head to catch Calloway’s gaze. Steam curled between them, softening the sharp angles of the doctor’s face. "Or maybe I just like hearing you talk."
Calloway’s thumb brushed the Chief’s pulse point, slow and deliberate. "Irrelevant variables." His voice was quiet, but the Chief felt the way his breath stuttered when his free hand slid higher, tracing the ridge of Calloway’s hipbone.
The Chief exhaled sharply through his nose, fingers tightening around Calloway’s wrist — not pulling, just anchoring. Steam swirled between them, thick enough to obscure the glint of challenge in the doctor’s eyes. "Irrelevant, huh?" His thumb pressed into Calloway’s pulse point, mirroring the doctor’s earlier move with deliberate precision. "Then shut me up."
Calloway twisted his grip, flipping their positions with a fluidity that belied his lean frame. The Chief’s back hit the rock with a muffled thud, water sloshing over the edge of the alcove. Calloway crowded forward, his knee slotting between the Chief’s thighs with unerring accuracy. "Hypothesis confirmed," he murmured, lips brushing the shell of the Chief’s ear. "Verbal override ineffective."
The Chief groaned as Calloway's teeth grazed his earlobe, the sharp sting cutting through the haze of steam and exhaustion. His hands found purchase on Calloway’s hips, fingers digging into the flex of muscle there — not guiding, just holding on. "Christ, doc," he muttered, voice raw. "You gonna make me work for it?"
Calloway exhaled against the Chief’s neck, slow and deliberate, before pulling back just enough to meet his gaze. His pupils were blown wide, the clinical detachment from earlier fractured by something hotter, hungrier. "Control group requires participation," he murmured, thumb brushing the Chief’s lower lip.
The Chief groaned as Calloway's knee pressed higher, grinding against him with deliberate pressure. Steam coiled between their bodies, turning the alcove into a private inferno. Calloway’s breath was hot against the Chief’s neck, his teeth leaving a trail of barely-there marks that wouldn’t bruise — just enough to make the older man shudder. "Still observing," Calloway murmured, voice rough. "But participation’s required for valid results."
The Chief laughed, breathless, tilting his head back as Calloway’s hand slid between them, fingers wrapping around him with the same calculated precision he’d used earlier. "Jesus fucking —" His hips jerked forward, water sloshing over the edge of the rock. Calloway’s grip tightened just enough to make the Chief’s thighs tremble. "You’re — ah — you’re a goddamn sadist."
"Clinical," Calloway corrected, thumb swiping over the head of the Chief’s cock in a slow, maddening circle. The Chief groaned, fingers digging into Calloway’s shoulders hard enough to leave temporary divots in the muscle. Steam condensed on their skin, droplets rolling down Calloway’s spine as he leaned in, lips brushing the shell of the Chief’s ear. "Vocalization suggests imminent completion."
The Chief's laugh dissolved into a groan as Calloway's hand twisted on the upstroke, water slick between them making every movement effortless. His head thudded back against the rock, exposing the thick cord of his throat where steam beaded and rolled downward. Calloway watched the droplets trace the Chief's collarbone with detached fascination before leaning in to catch one with his tongue — a deviation from protocol that made the older man shudder.
"Fucking hell," the Chief gasped, fingers tightening in Calloway's hair hard enough to pull. "You're —" His words fragmented when Calloway's thumb pressed just beneath the head, circling in that same infuriatingly precise rhythm. Water sloshed between them as the Chief's hips jerked forward, his thigh muscles quivering with restrained motion.
Calloway's fingers tightened fractionally, his grip shifting just enough to make the Chief hiss through his teeth. Steam curled between them, thickening the air until the Chief could barely see the sharp angles of Calloway's face — just the heat of his mouth hovering inches away, the glint of focus in his eyes. "Jesus," the Chief muttered, fingers scrabbling at the rock behind him. "You're gonna —" His voice cracked when Calloway's thumb pressed harder, circling the sensitive spot beneath the head with relentless precision.
The Chief's thighs trembled, his hips stuttering forward involuntarily. Water lapped at their waists, sloshing over the edge of the rock with each ragged thrust. Calloway exhaled sharply through his nose, his own control fraying at the edges — evident in the way his fingers trembled slightly against the Chief’s skin, the way his breath hitched when the older man dragged blunt nails down his spine.
The Chief's groan vibrated against Calloway's shoulder, rough and desperate, as the doctor's fingers twisted just so — his grip relentless, his rhythm unyielding. Steam curled around them in thick tendrils, obscuring everything but the heat of Calloway's palm and the ragged hitch of the Chief's breathing. "Fuck —" the Chief gasped, fingers scrabbling at Calloway's back, blunt nails leaving fleeting marks that would fade within minutes. "Goddamn — you're —" His words dissolved into a choked noise as Calloway's thumb pressed harder, circling that spot with clinical precision.
Calloway watched the Chief unravel with detached fascination — the way his pupils dilated, the way his throat worked around silent curses, the way his hips jerked forward helplessly. Water sloshed between them, lapping at their waists in heated waves, but neither noticed. The Chief's fingers twisted in Calloway's hair, not guiding, just anchoring — as if he might float away if he let go. "Close," he managed, voice cracking. "Fuck, I'm —"
The Chief's warning shattered into a groan as Calloway's mouth crashed onto his again, swallowing the sound with a hunger that bordered on desperation. Steam curled around them like a living thing, thickening the air until every inhale burned with heat and the scent of wet stone. Calloway's hand never stopped moving, his grip perfectly calibrated to drag the Chief to the edge and hold him there — relentless, unwavering. The Chief's fingers spasmed in Calloway's hair, his hips jerking erratically against the doctor's palm.
Then Calloway twisted his wrist just so — a sharp, calculated motion — and the Chief came apart with a choked shout, his back arching off the rock as pleasure ripped through him. Water sloshed violently over the edge of the alcove, droplets hitting the stone like scattered applause. Calloway didn't ease his grip, drawing out the aftershocks until the Chief batted weakly at his wrist, breath coming in ragged bursts.
The Chief sagged against the rock, breath ragged, sweat and steam blending into a slick sheen across his chest. Calloway’s hand lingered, fingers tracing idle patterns on the Chief’s hipbone — a touch that felt more possessive than clinical now. The older man chuckled, throat raw, and swatted weakly at Calloway’s wrist. "Goddamn," he rasped, thumb brushing the doctor’s lower lip. "You’re a menace with hands like that."
Calloway exhaled sharply through his nose, his gaze dropping to where his fingers still pressed into the Chief’s skin. Steam curled between them, softening the sharp lines of his face. "Observational data suggests satisfactory results," he murmured, but the roughness in his voice betrayed him.
The Chief's laugh was a rough, breathless thing as he dragged Calloway down by the nape of his neck, their foreheads bumping together. Steam clung to their skin where they touched, water pooling between their bodies in heated waves. "Satisfactory, my ass," he muttered, thumb scraping over Calloway's stubble. His other hand slid down the doctor's flank, fingers splaying over the tense muscle there. "You're wound tighter than a goddamn drum."
Calloway caught the Chief's wrist, stilling his progress. His grip wasn't harsh, but there was no give in it either. "Control group requires reciprocity," he murmured, voice low enough that the words vibrated against the Chief's collarbone.
The Chief's grin was all teeth, sharp and knowing, as he twisted his wrist free with surprising ease — years of handling hose lines under pressure had left his grip stronger than most expected. Steam rolled between them as he surged forward, flipping their positions with a fluidity that sent water sloshing against the alcove walls. Calloway's back hit the rock with a muted thud, the doctor's eyebrows lifting fractionally at the sudden reversal.
"Reciprocity, huh?" The Chief's voice was gravel wrapped in velvet, his palm sliding up Calloway's sternum to settle over his pounding pulse. He leaned in until his lips brushed the shell of the doctor's ear. "Then stop thinking." His teeth grazed cartilage, not hard enough to mark — just enough to make Calloway's breath stutter.
Calloway's hands locked around the Chief's waist, fingers digging into the dense muscle there. Steam coiled between them, thick enough to obscure the way his pupils dilated when the Chief's teeth scraped his earlobe again. "You're —" Calloway started, voice rough, but the Chief cut him off with a sharp nip to his jaw.
"Shut up," the Chief muttered, dragging his palm down Calloway's abdomen with deliberate pressure. His fingers traced the surgical scar along Calloway's flank — sober now, no teasing left in the touch — before continuing lower. Water sloshed between them as he shifted forward, his grip tightening around Calloway with unmistakable intent. "Your turn."
The Chief's hand wrapped around Calloway with rough certainty, his grip tight enough to make the doctor's hips jerk forward instinctively. Steam curled between them in thick tendrils as the Chief leaned in, his breath hot against Calloway's ear. "Still observing?" he taunted, thumb pressing into the hollow of Calloway's hipbone with deliberate precision.
Calloway's exhale came out ragged, his fingers tightening convulsively on the Chief's shoulders. His usual detached commentary failed him — just a sharp intake of breath as the Chief's palm slid up his length with agonizing slowness. Water lapped at their waists, sloshing against the rock with each erratic movement.
Calloway's breath hitched audibly when the Chief twisted his wrist on the upstroke, water slick between them making every movement effortless. His fingers dug into the Chief's shoulders hard enough to leave temporary divots in the muscle, his clinical detachment fracturing with each ragged exhale. Steam condensed on Calloway's lashes, droplets rolling down his cheekbones as the Chief leaned in, lips brushing the shell of his ear. "Still taking notes?" the Chief murmured, voice rough with satisfaction.
The doctor's response dissolved into a groan as the Chief's thumb pressed just beneath the head, circling in slow, deliberate rotations that made Calloway's thighs tremble. Water sloshed violently against the alcove walls when Calloway's hips jerked forward involuntarily, his back arching off the rock. The Chief chuckled darkly, fingers tightening around him. "That's it," he muttered against Calloway's jaw. "Clock's ticking, doc."
Calloway's breath stuttered against the Chief's shoulder when the older man's thumb pressed harder — not cruel, just insistent — right where the doctor's control was fraying fastest. Steam thickened between them, obscuring the sharp hitch of Calloway's ribs as his breathing fractured. The Chief grinned against his collarbone, teeth scraping skin just shy of marking. "There you are," he murmured, fingers twisting just so on the upstroke.
Water sloshed over the alcove's edge as Calloway's hips jerked forward, his abdominal muscles contracting under the Chief's palm. His fingers scrabbled at the rock behind him, knuckles whitening — no clinical detachment left, just raw response. The Chief watched the way Calloway's throat worked around silent curses, the way his pupils dilated until the grey was nearly swallowed.
Calloway's back arched off the rock as the Chief's thumb pressed harder — circling, relentless — his breath coming in sharp, punched-out gasps that fogged the steam between them. The Chief grinned against his collarbone, feeling the doctor's pulse hammer under his lips. "Goddamn," he muttered, tightening his grip just enough to make Calloway's hips stutter forward. "You're loud when you're not thinking."
The observation shattered what remained of Calloway's restraint. His hands locked around the Chief's biceps, fingers digging into dense muscle as he dragged the older man closer, their bodies colliding with a splash that sent water cascading over the alcove's edge. Steam curled around them like a living thing, thickening the air until every inhale burned.
Calloway's fingers dug into the Chief’s biceps hard enough to leave fleeting marks as the older man twisted his wrist again — water slick between them, steam curling around their colliding hips. The Chief watched Calloway’s control fracture in real time — the sharp inhale through his nose, the way his throat worked around a silent curse, the tendons in his neck standing out like cables under strain. "There it is," the Chief murmured, thumb pressing into the hollow of Calloway’s hipbone where his pulse thundered. "Christ, doc. You’re wound tight."
Calloway’s response was a ragged exhale, his hips jerking forward as the Chief’s grip tightened fractionally. Water sloshed violently over the rock, droplets hitting their shoulders like scattered rain. The steam between them thickened, obscuring everything but the heat of the Chief’s palm and the desperate hitch of Calloway’s breathing. "Still —" Calloway started, voice cracking, but the Chief cut him off with a sharp nip to his jaw.
The Chief’s fingers curled tighter, his grip shifting to that perfect, maddening pressure that made Calloway’s vision flicker at the edges. Water sloshed between them with each erratic thrust, droplets hitting the rock like punctuation marks to the doctor’s unraveling. Calloway’s head thudded back against the stone, exposing the taut line of his throat where steam condensed and rolled downward. The Chief followed the path with his tongue — slow, deliberate — before biting just above the collarbone, hard enough to make Calloway hiss.
"Feedback?" the Chief taunted, twisting his wrist on the upstroke in a way that made Calloway’s hips jerk forward uncontrollably. His laughter vibrated against Calloway’s damp skin. "Or are you done taking notes?"
Calloway's fingers convulsed against the Chief's shoulders, blunt nails digging into wet skin as the older man's relentless strokes pushed him toward the edge. Steam swirled thick between them, obscuring the way Calloway's jaw clenched — his usual clinical detachment fracturing under the Chief's knowing hands. Water sloshed violently against the alcove walls when Calloway arched forward, a ragged groan tearing from his throat as the Chief's thumb pressed just beneath the head in slow, torturous circles.
"Jesus —" Calloway's voice cracked, his hips stuttering against the Chief's grip. His fingers scrabbled at the rock behind him, knuckles whitening as his thighs trembled with the effort to hold still. The Chief grinned against his collarbone, teeth scraping skin just shy of leaving marks.
The Chief's chuckle vibrated against Calloway's sternum as the doctor's fingers twisted in his hair — not guiding, just anchoring. Water dripped from their tangled limbs onto the sun-warmed rock beneath them, the sound lost in the ragged hitch of Calloway's breathing.
"Look at you," the Chief murmured, his thumb swiping a droplet from Calloway's lower lip. His other hand never stopped moving, twisting just enough on the upstroke to make Calloway's abdomen flex violently. "All that control, gone to shit."
The Chief watched Calloway come undone beneath him — every muscle straining, every tendon taut as a bowstring. Steam coiled between them, thickening the air until each inhale was a lungful of wet heat. Calloway's breath stuttered when the Chief's thumb pressed just beneath the head again, circling in slow, relentless rotations that made his vision flicker at the edges.
"Christ —" Calloway's voice was wrecked, his fingers twisting in the Chief's hair hard. His hips jerked forward helplessly, water sloshing over the edge of the alcove in heated waves. "Don't —"
The Chief's laugh was low and satisfied against Calloway's throat as the doctor's protest dissolved into a groan, his hips jerking forward uncontrollably. Steam clung to their skin where they pressed together, water sloshing between them in heated waves that matched the erratic rhythm of Calloway's breathing. The Chief twisted his wrist just once more — a sharp, calculated motion — and Calloway came apart with a choked sound, his fingers locking around the Chief's biceps hard enough to leave temporary divots in the muscle.
Water lapped at their waists as Calloway sagged back against the rock, chest heaving, his usual clinical detachment shattered beyond recognition. The Chief watched him with dark amusement, thumb brushing a droplet from Calloway's lower lip where it was slightly swollen from kissing. "Feedback?" he murmured, voice rougher than before.
Calloway exhaled sharply through his nose, fingers still twitching where they gripped the Chief's shoulders. His pulse hammered visibly at his throat, the only betrayal of his usual composure. Steam curled between them in lazy spirals as the Chief grinned, smugness radiating off him in waves.
The Chief's thumb traced Calloway's lower lip again, lingering just long enough to make the doctor's breath hitch. "Speechless?" he murmured, voice dripping with satisfaction. "That's a first."
The Chief's grin widened as Calloway finally caught his breath, his fingers loosening their death grip on the older man's shoulders. Steam curled lazily between them, softening the sharp angles of Calloway's face as he blinked up at the Chief with uncharacteristic dazedness. The Chief chuckled, swiping a thumb across Calloway's damp collarbone. "Never thought I'd see the day," he murmured, voice rough with amusement. "Dr. Calloway, rendered speechless by something as unscientific as a good handjob."
Calloway exhaled sharply through his nose, his fingers flexing against the Chief's biceps before sliding away to brace against the rock behind him. Water lapped at their waists, the heat of it still intense despite the cool evening air creeping in around the grotto's edges. "Statistical anomaly," Calloway muttered, but the rasp in his voice undermined the deflection.
The Chief’s laughter rumbled low against Calloway’s sternum, fingers still idly tracing the doctor’s ribs where they rose and fell with uneven breaths. Steam curled between them in thick tendrils, softening the edges of Calloway’s sharp inhale when the Chief’s thumb brushed a sensitive spot just below his navel. "Anomaly, huh?" The Chief’s voice was gravel wrapped in velvet, his breath hot against Calloway’s damp skin. "Guess we’ll need to replicate the experiment. For science."
Calloway’s fingers twitched against the rock, water dripping from his wrist onto the sun-warmed stone. His usual razor-sharp retort died on his tongue when the Chief’s palm slid up his flank, pausing at the jagged scar tissue along his ribs — the one he’d dismissed earlier with a clipped "Mogadishu." This time, the Chief didn’t ask, just pressed his lips to the raised flesh in a kiss that wasn’t clinical at all.
The Chief's mouth lingered on the scar longer than necessary — long enough for Calloway's breath to hitch, long enough for his fingers to tighten against the rock behind him. Steam curled between them, thickening the air until Calloway could taste the humidity on his tongue, the salt of the Chief's skin beneath it.
"Still observing?" the Chief murmured against the scar, lips brushing the uneven tissue with deliberate gentleness. His hand slid higher, tracing the ridges of Calloway's ribs with rough familiarity.
Calloway's fingers flexed against the rock, knuckles whitening as the Chief's mouth lingered on the scar — too intimate, too knowing. Steam curled between them in lazy spirals, thick enough to obscure the way Calloway's throat worked around a silent swallow. "Data collection requires —" His voice cracked when the Chief's teeth grazed the scar's edge, not hard enough to mark, just enough to make his ribs twitch beneath the touch.
The Chief chuckled against his skin, breath hot and damp. "Bullshit." His palm slid up Calloway's sternum, pausing over the frantic hammer of his pulse. "You're done observing." His thumb pressed into the hollow of Calloway's throat, just shy of rough. "Now you're participating."
Calloway's breath hitched when the Chief's teeth scraped his scar again — not clinical, not detached, just raw sensation that arced down his spine like live voltage. Steam thickened between them, curling around the Chief's shoulders as he leaned in, his grip sliding from Calloway's ribs to the small of his back. "Still analyzing?" the Chief murmured against his collarbone, fingers pressing into the tense muscle there with deliberate pressure.
Calloway exhaled sharply through his nose, his fingers twitching against the rock behind him. Water sloshed against their waists as the Chief shifted closer, his knee slotting between Calloway's thighs with unerring precision. "Variables —" Calloway started, voice rough, but the Chief cut him off with a sharp nip to his jaw.
The Chief’s teeth grazed Calloway’s earlobe, sharper than before, and the doctor’s breath stuttered — a hitch that had nothing to do with clinical observation. Steam coiled around them, thick enough to obscure the way Calloway’s fingers dug into the Chief’s shoulders, blunt nails leaving crescent indents in wet skin. "Variables my ass," the Chief muttered against his jaw, thumb pressing into the hollow of Calloway’s throat where his pulse rabbited. "You’re just stubborn."
Calloway’s retort dissolved into a groan when the Chief’s knee pressed higher, grinding against him with deliberate, maddening pressure. Water sloshed violently over the alcove’s edge, droplets hitting the rock like scattered applause. The Chief grinned, all teeth, as Calloway’s hips jerked forward involuntarily — proof that even a man trained to withstand interrogation had his breaking points.
The Chief’s grin sharpened as Calloway’s fingers dug into his shoulders — not resisting, just clinging. Steam fogged the alcove, turning the doctor’s sharp exhales into visible puffs against the Chief’s collarbone. "Still with me?" the Chief taunted, rolling his hips forward to press Calloway harder against the rock. Water sloshed over their thighs, hot enough to redden skin.
Calloway’s response was a gritted curse, his head thudding back against stone as the Chief’s teeth found his earlobe again. The doctor’s usual precision fractured into raw reflex — hips jerking, breath ragged — while the Chief mapped every twitch with smug satisfaction. "There it is," he murmured against Calloway’s damp temple. "No more variables. Just this." His hand slid between them, calloused fingers wrapping around Calloway with practiced certainty.
Calloway’s breath tore from his lungs in a ragged gasp as the Chief’s hand closed around him again — hot, rough, and utterly insistent. Steam coiled between their bodies, thick enough to blur the edges of the Chief’s smirk as he twisted his wrist on the upstroke, water slick between them making every movement effortless. Calloway’s fingers scrabbled at the rock behind him, knuckles whitening, his usual detached commentary reduced to fractured syllables. "Christ —" he managed, voice cracking as the Chief’s thumb pressed just beneath the head in slow, torturous circles.
The Chief chuckled against Calloway’s collarbone, teeth scraping skin just shy of marking. "Not so clinical now, are you?" His grip tightened fractionally, dragging a shudder from the doctor’s frame. Water sloshed violently against the alcove walls as Calloway’s hips jerked forward, his thighs trembling with the effort to hold still. The Chief watched the unraveling with dark satisfaction — the way Calloway’s throat worked around silent curses, the way his pupils swallowed the grey of his irises whole.
Calloway's fingers clenched against the rock behind him, tendons standing out like cables under strain as the Chief's thumb circled that spot again — deliberate, relentless. Water sloshed over the alcove's edge in heated waves with each erratic thrust of Calloway's hips, droplets hitting their shoulders like scattered applause. Steam curled thick between them, softening the sharp edges of Calloway's gasps into something ragged and unguarded.
"Feedback?" The Chief murmured against his jaw, fingers tightening just shy of rough. His breath was hot where it fanned across Calloway's damp skin, lips brushing the doctor's racing pulse. "Or are we past analysis now?"
The Chief's thumb pressed harder — circling, relentless — and Calloway's hips jerked forward uncontrollably, water sloshing over the alcove's edge in a heated rush. His breath came in ragged bursts, fingers scrabbling against the rock behind him for purchase as the Chief's grip twisted just shy of cruel on the upstroke. Steam thickened between them, clinging to Calloway's lashes where they fluttered shut for a fractured second before forcing open again — as if refusing to miss a moment of his own undoing.
"Still —" Calloway started, voice cracking around the word, but the Chief cut him off with a sharp nip to his jaw.
The Chief’s laugh rumbled low against Calloway’s sternum as he abruptly lifted him — one arm hooked under his knees, the other bracing his back — with the same effortless strength he’d use hauling a hose line. Steam curled around them as Calloway’s fingers instinctively gripped the Chief’s biceps, his usual protest dying when the older man nipped at his jaw. "Decompression protocols, doc," the Chief murmured, carrying him through the grotto’s exit like it was nothing, water sluicing off their bodies onto the flagstone path.
Calloway’s breath hitched — not from the movement, but from the way the Chief’s hands flexed against his skin, possessive and sure, as he strode past the alcove’s privacy screen. The night air was cooler here, the desert breeze licking at their damp skin, but the Chief’s grip was furnace-hot. "Unnecessary," Calloway managed, though his voice lacked its usual edge, roughened by the Chief’s earlier attentions. The Chief just grinned, thumb brushing the scar on Calloway’s flank in silent contradiction.
The Chief’s footsteps echoed against the flagstones as he carried Calloway toward the cedar-lined cabana at the grotto’s edge — one of the club’s more secluded retreats, half-hidden by palo verde trees. Steam still curled off their skin in the cooler night air, mingling with the scent of creosote and sunbaked stone. Calloway’s fingers flexed against the Chief’s shoulders, not protesting now, just anchoring — his usual clinical detachment frayed beyond recognition.
The cabana door swung open with a nudge from the Chief’s shoulder, revealing a space dominated by a low, wide bench piled with towels and cushions. Moonlight filtered through the slatted roof, striping their bodies as the Chief deposited Calloway onto the nearest surface with deliberate care. Water dripped from Calloway’s hair onto the cedar planks, the sound loud in the sudden quiet.
The Chief's knees hit the cedar bench with a muted thud, his hands braced on either side of Calloway's hips as steam curled off their skin in the moonlit cabana. Water dripped from Calloway's hair onto the wood between them, each drop a punctuation mark to the silence. The Chief grinned — that infuriating, knowing grin — and leaned in until his breath ghosted over Calloway's jaw. "Still cataloging variables, doc?"
Calloway exhaled sharply through his nose, fingers twitching against the bench. The Chief's proximity was a live wire, his body heat radiating against Calloway's damp skin even as the desert night cooled around them. "Decompression protocols require —"
The Chief's palm pressed flat against Calloway's sternum before the doctor could finish his sentence, fingers splaying wide over the damp skin still thrumming with aftershocks. "Hush," the Chief murmured, low and rough against Calloway's temple as he maneuvered them both sideways onto the bench in one fluid motion. Cedar groaned under their combined weight as the Chief hauled Calloway against him — no clinical distance left, just heat and the heavy press of muscle under slick skin.
Calloway exhaled sharply through his nose, but didn't resist when the Chief's arm locked around his ribs, fingers spanning the scar tissue with unconscious precision. Steam curled off their bodies in the cooler night air, mingling with the scent of sun-warmed cedar and the salt-tang of exertion. The Chief's breath evened out against the back of the doctor's neck — a silent counterpoint to the erratic pulse still hammering in Calloway's throat.
Calloway's breath hitched when the Chief's forearm tightened across his ribs — not restraining, just anchoring — as the older man shifted behind him. Steam still curled off their damp skin in lazy spirals, rising to mingle with the scent of sun-warmed cedar. The Chief's thumb traced absent circles over Calloway's hipbone, his callouses catching slightly on wet skin. A desert breeze ghosted through the cabana's slatted walls, raising gooseflesh along Calloway's flank where the Chief's chest pressed against his back.
"Breathe, doc," the Chief murmured against the nape of Calloway's neck, lips brushing the damp hairline. His voice had lost its earlier taunting edge, softened into something that vibrated through Calloway's spine like a tuning fork. The doctor's fingers twitched against the bench where they'd been braced — ready to push away, to reclaim control. But the Chief's palm slid up his sternum, pressing flat over his still-racing heartbeat, and something in Calloway's shoulders loosened against his will.
Calloway exhaled slowly through his nose, the tension in his shoulders unraveling strand by strand as the Chief's forearm remained anchored across his ribs — not confining, just present. The cedar bench creaked faintly under their combined weight as the Chief shifted behind him, his breath warm against the nape of Calloway's neck. Steam still curled off their skin in the night air, mingling with the scent of sunbaked wood and the Chief's aftershave — something woodsy and uncomplicated, like the man himself.
A desert breeze slipped through the cabana's slatted walls, raising gooseflesh along Calloway's flank where the Chief's chest pressed against his back. "There you go," the Chief murmured, his voice a low rumble that vibrated through Calloway's spine. The words weren't teasing now — just an observation, soft at the edges.
Calloway's lashes fluttered once—twice—before finally lowering, surrendering to the warmth of the Chief's chest pressed against his back. The cedar beneath them smelled of sun and sap, the scent grounding in a way that had nothing to do with clinical observation. The Chief's forearm remained anchored across his ribs, not restraining, just present—an unspoken assurance that unraveled the last of Calloway's resistance. Steam still curled off their skin in lazy spirals, mingling with the desert night air slipping through the cabana's slats.
