Chapter 4: Unplanned Threesome
The sharp crack of the door slamming against the wall shattered the heavy silence. Stiles stood frozen in the doorway, chest heaving, his lanky frame a stark silhouette against the brighter light of the hallway. His eyes, wide as saucers, scanned the scene: the rumpled sheets, the discarded clothes, the lingering scent of sex, pine, and sweat thick enough to taste.
His gaze locked onto the bed. Derek bent forward, arms braced, his back a taut arch, smooth skin gleaming with sweat. Below him, Scott was seated upright against the headboard, his powerful legs spread. And between them, connecting them with brutal intimacy, was Scott’s thick, flushed cock buried impossibly deep in Derek’s slick, stretched hole. Derek’s asscheeks clenched rhythmically around the intrusion, a wet, obscene sound punctuating each shallow rise and fall of Scott’s hips. A low, possessive growl vibrated from Scott’s chest, his eyes blazing crimson as they snapped up to meet Stiles’ stunned stare.
Stiles’ mouth hung open. The frantic energy that usually animated him was replaced by utter stillness, save for the way his Adam's apple bobbed frantically. His pupils dilated, swallowing the warm brown of his irises. His worn jeans visibly tightened across the crotch, the outline of his own impressive cock straining against the denim, undeniable proof of the effect the raw display had on him. He smelled like adrenaline, shock, and a sudden, overwhelming surge of arousal.
Scott’s growl deepened, resonating through the room. His hips didn’t stop their slow, deliberate grind upwards into Derek’s tight heat, making Derek whimper softly, his own cock dripping onto the sheets beneath him. Scott’s voice, when it came, was a rough command, stripped of its usual warmth, pure Alpha dominance. "Stiles. Get in or get out. Now."
The ultimatum hung in the air. Stiles flinched, his eyes darting from Scott’s intense glare to Derek’s exposed form, the way his muscles trembled with each shallow thrust Scott delivered. Derek turned his head slightly, meeting Stiles’ gaze over his shoulder. There was no fear there, just a hazy, desperate need, slick visibly glistening at his stretched rim around Scott’s girth. Derek’s lips parted, a silent plea escaping on a shaky exhale.
It broke something in Stiles. The paralysis shattered. He stumbled forward, kicking the door shut behind him with a clumsy thud. His fingers fumbled at his belt buckle, trembling. "Fuck. Okay. Yeah. Okay." His voice was breathless, high-pitched with panic and lust. He ripped his belt open, yanked his jeans and boxers down his hips in one frantic motion. His cock sprang free, thick and already leaking, bobbing heavily. He was surprisingly well-endowed, the flushed head glistening, veins prominent along the shaft.
Scott watched him, a predatory satisfaction flickering in his eyes alongside the primal heat. He kept grinding into Derek, his pace deliberate, possessive. "Lock it," Scott ordered, his voice a low rumble.
Stiles scrambled, turning the lock with clumsy fingers before turning back, his gaze fixed on Derek’s ass, on the hypnotic slide of Scott’s cock in and out of that slick hole. He licked his lips. "What… what do I…?"
"Get over here," Scott commanded, his hand leaving Derek’s hip to gesture Stiles closer. "His mouth. Use it."
Stiles moved like he was in a trance, drawn to the heat radiating from the pair on the bed. He dropped to his knees beside the bed, right in front of Derek’s lowered head. Derek’s dark hair was plastered to his forehead with sweat, his lips swollen, eyes dark and needy. Without hesitation, Derek craned his neck, his tongue darting out to swipe a hot, wet stripe up the underside of Stiles’ cock from root to tip.
Stiles choked on a gasp. "Holy shit!" His hand flew to Derek’s hair, fingers tangling in the dark strands, not guiding yet, just holding on as Derek’s mouth engulfed the head, swirling his tongue expertly around the sensitive ridge. Derek moaned around him, the vibration shooting straight to Stiles’ balls, the sound amplified by the wet suction. Derek’s eyes fluttered shut, lost in the dual sensation of Scott’s cock stretching his ass and the heavy weight of Stiles’ cock on his tongue.
Scott watched, his own breathing hitching as Derek’s moan vibrated around Stiles’ cock. He increased his pace, thrusting deeper, harder. The wet slap of his hips against Derek’s ass intensified. "Suck him, Derek," Scott growled. "Show him what that pretty mouth does. Show him why the Omega’s so good."
Derek obeyed eagerly. He hollowed his cheeks, taking Stiles deeper, his nose pressing into the coarse hair at Stiles’ base. Stiles threw his head back with a ragged cry, his hips jerking forward involuntarily. "Fuck! Oh fuck, Derek!" His grip tightened in Derek’s hair, forcing him down further. Derek relaxed his throat, taking the thick intrusion, gagging slightly but sucking hard, his tongue working frantically along Stiles’ shaft. Pre-come flooded Derek’s mouth, salty and bitter, mixing with the slick taste of his own arousal coating Scott’s cock inside him. The obscene wet sounds filled the room – Derek sucking Stiles, Scott pounding Derek, the slick squelch of Derek’s hole stretched around Scott’s girth.
Stiles was babbling, a stream of broken praise and filthy encouragement. "Yeah, suck it! Just like that, you filthy fucking… ah! Christ, your mouth! Swallow it all, c’mon!" He started fucking Derek’s mouth in short, shallow thrusts, meeting Derek’s eager suction. His cock pulsed heavily on Derek’s tongue.
Scott’s rhythm became erratic, his thrusts harder, deeper. He could feel Derek’s slick channel clenching tighter around him, the vibrations from Derek moaning around Stiles’ cock adding an extra layer of stimulation. Derek’s own neglected cock was drooling steadily onto the sheets, untouched. Scott slammed in deep, grinding his pelvis against Derek’s ass. "Gonna fill this tight cunt, Omega," Scott snarled, his control fraying. "You want it? Want my cum deep in that greedy hole?"
Derek couldn’t speak, stuffed full, but he moaned desperately around Stiles’ cock, the sound muffled but unmistakably affirmative, his body trembling between them.
Stiles felt the frantic clenching of Derek’s throat. "Fuck, I’m gonna… Derek!" he gasped, warning sharp but lost in the haze. His hips snapped forward one last time, burying himself to the root in Derek’s wet heat. Thick jets of cum erupted down Derek’s throat. Derek swallowed convulsively, his throat working around Stiles’ pulsing cock, taking every drop, his body shuddering violently as the salty flood hit his system.
The intense clenching of Derek’s throat as he swallowed, combined with the visual of Stiles emptying himself down Derek’s throat and the vice-like grip of Derek’s ass spasming around his own cock, was too much for Scott. With a roar that shook the room, he slammed home, grinding deep as he emptied himself in powerful, pulsing bursts deep inside Derek’s slick channel. Hot cum flooded Derek, adding to the mess, the sensation blinding.
Derek convulsed between them, impaled on Scott and still sucking the last drops from Stiles’ softening cock. His own cock jerked wildly, untouched, splattering thick ropes of cum onto the sheets beneath him with each powerful spasm triggered by the dual stimulation and the feeling of being filled.
Stiles slumped back, gasping, his hard cock cock slipping wetly from Derek’s lips with a lewd pop. Derek collapsed forward onto the bed, utterly spent, Scott’s still hard cock slipping from his gaping, dripping hole. Scott leaned back against the headboard, chest heaving, sweat dripping down his temples. The room reeked of sex, sweat, come, and the lingering scent of pine.
The stale sweetness of spent passion hung thick in the air, mingling with the sharp tang of male sweat and the underlying evergreen scent clinging to Scott’s sheets. Derek lay collapsed between them, chest heaving, spent cock twitching weakly against the damp fabric, his asshole glistening and gaped. Scott shifted, his own breathing still heavy, a satisfied rumble vibrating in his chest as he propped himself up on his elbows. He looked down at Derek, then at his own softening cock, slick with a mix of Derek’s natural lube and his own drying release.
"Omega," Scott commanded, his voice rough but lacking its earlier snarl, more like gravel under tires. He tapped his sticky cockhead against Derek's hipbone. "Clean it up. Get over here and suck me clean."
Derek pushed himself up onto unsteady hands, a faint flush creeping up his neck under the sheen of sweat. He avoided Stiles's wide, fascinated eyes as he shuffled on his knees towards Scott. Stiles hadn’t moved from his slumped position near the foot of the bed, his softening cock resting against his thigh, but his gaze tracked Derek’s every movement with renewed intensity. Derek reached Scott, his dark lashes lowered, his blush deepening as he leaned in.
He didn’t hesitate, though. Wrapping his fingers loosely around the base of Scott’s cock, he engulfed the flared head, swirling his tongue firmly around the sensitive ridge. A low groan escaped Scott as Derek worked, his mouth hot and wet and obscenely skilled. Derek pulled off slowly, his lips dragging along Scott’s length, then dipped his head to lick a broad, slow stripe up the thick vein on the underside. He nosed at Scott’s balls for a second, breathing deep, then kissed the swollen head softly before taking it back into his mouth, sucking hard.
Stiles watched, transfixed, his cock twitching noticeably back to life against his leg. The sight of Derek, flushed and vulnerable yet utterly focused on servicing Scott’s cock, was doing things to him. Derek’s ass, still glistening with slick and cum, flexed slightly as he bobbed his head. A low, involuntary sound came from Stiles’s throat as Scott’s cock visibly thickened again in Derek’s talented mouth. "Fuck me," Stiles breathed, his hand drifting down to grip his own hardening shaft.
Scott tangled a hand in Derek's dark hair, not forcing, just holding. "Look at him, Derek," Scott murmured, his voice thick. "Look how hard you make him just by sucking my dick." Derek’s eyes flickered up, meeting Stiles’s hungry stare for a fleeting second, his cheeks burning crimson even as he hollowed his cheeks around Scott’s cock, sucking with wet, filthy noises. Stiles groaned again, louder this time, his cock now fully erect, pulsing in his fist.
"Can't just watch," Stiles muttered, his voice tight with need. He pushed himself up, crawling onto the bed behind Derek. He ran a shaky hand over Derek’s slick, marked asscheeks, fingers brushing against the stretched, wet rim. "Gotta feel that hole again." He spat roughly onto his palm, slicked his thick cockhead, and without preamble, pressed it against Derek’s entrance. Derek gasped around Scott’s cock, his body tensing, then relaxing as Stiles pushed in with a single, forceful thrust, burying himself to the hilt in Derek’s slick heat.
"God, fuck!" Stiles cried out, his head falling back as Derek’s ass clenched rhythmically around his invading cock. He gripped Derek’s hips, fingers digging into the firm muscle, and began fucking him in deep, measured strokes. The wet slap of skin on skin resumed, a counterpoint to the slick sounds of Derek working Scott’s cock. Derek moaned, a deep vibration that traveled down Scott’s shaft, making the Alpha hiss. Stiles drove into him, grunting with each powerful thrust, his eyes fixed on the flexing muscles of Derek’s back, on the way Scott’s cock disappeared between Derek’s lips. "So fucking tight… even after Scott wrecked it… fuck, Derek!"
Scott’s breathing grew ragged again, his hips lifting slightly off the bed to push deeper into Derek’s throat. He could feel the rhythmic clench and release around the base of his cock where Stiles was pistoning in and out. "Gonna come," Scott gritted out, his hand tightening in Derek’s hair. "Gonna paint that pretty face." He pulled his cock free from Derek’s mouth with a wet pop, glistening and fully hard again. Derek gasped for air, lips swollen and slick, his eyes dazed.
Before Derek could react, Scott gripped his cock and aimed. Thick, white ropes of hot cum erupted, splattering across Derek’s cheek, his jaw, catching in his eyelashes, and landing on his open, panting mouth. Derek flinched slightly but didn’t pull away, his tongue darting out instinctively to catch a drop on his lower lip, his eyes wide and vulnerable under the mess.
Stiles’ hips stuttered as he watched Scott’s hot spunk splatter across Derek’s stunned, beautiful face. The stark white streaks painted his cheekbone, dotted his jaw, clung to the dark fringe of his lashes – obscene against his flushed skin. Derek’s pink tongue darted out, catching a milky drop on his swollen lower lip, his wide eyes fixed on Stiles, raw and unguarded beneath the mess.
A guttural groan tore from Stiles’ throat. That face. He needed it. Needed to see it properly. "Jesus fucking Christ," Stiles gasped, his voice thick. His cock throbbed violently inside Derek’s slick heat. He pulled out in one slick, wet withdrawal. The sudden emptiness made Derek gasp, his hole fluttering visibly.
Without a word, Stiles grabbed Derek’s hips with bruising force, leveraging his surprising strength. He hauled Derek backwards and flipped him roughly onto his back, the mattress groaning under their combined weight. Derek landed with a soft grunt, instinctively spreading his legs as Stiles shoved them wide apart, hands clamping onto his thighs. Scott’s cum smeared across the sheets beneath Derek’s ass.
"Look at you," Stiles choked out, his gaze raking over Derek’s body. His eyes devoured the ruin of his face – the streaks of Scott’s release gleaming wetly. Then he looked lower, his grip tightening on Derek’s trembling thighs. "His fucking spunk all over you. Look at this goddamn mess." His gaze dropped between Derek’s legs, past his own cock, thick and glistening with Derek’s slick. Derek’s hole was a slick, gaping pucker, swollen and glistening, Scott’s pearly cum leaking out around the rim, mixing with Derek’s own lubricant in a visible, wet smear down his balls and onto the sheets. "Your fucking hole’s dripping," Stiles breathed, awe and hunger warring in his voice. "Dripping Scott’s load. Look at it weep."
He didn’t wait. Keeping Derek’s legs splayed obscenely wide, Stiles lined himself up. The blunt, swollen head of his cock pressed hard against Derek’s stretched, slicked entrance. Derek groaned, his head falling back, his cum-smeared face exposed. "Yeah, fuck," Derek rasped, his voice wrecked.
Stiles pushed. The thick head breached him with a wet squelch, the tight ring of muscle yielding instantly, slicked by Scott’s cum and Derek’s own arousal. He sank deep in one relentless thrust, balls slapping hard against Derek’s slick asscheeks. Derek cried out, a high-pitched, broken sound. His cock jerked, spitting a fresh dribble of pre-come onto his belly. Stiles bottomed out, buried to the hilt, his own groan echoing Derek’s. "God, you’re fucking wrecked inside," Stiles gasped, his hips already pistoning. "So wet. So fucking ruined. Taking Scott’s load like a greedy little cunt and now me."
He set a brutal pace immediately. Short, sharp, deep jabs. His balls slapped wetly against Derek’s sensitive skin with every inward drive. The sound was obscene: wet flesh smacking, Stiles’ ragged panting, Derek’s choked gasps. Stiles leaned forward slightly, his eyes locked on Derek’s face. "Look at me, Derek," he demanded, his voice strained. "Look at me while I fuck Scott’s cum deeper into you."
Derek forced his eyes open, struggling to focus. Strands of dark hair stuck to the drying streaks of white on his forehead. His lips were parted, swollen, smeared with Scott’s release. Stiles watched, mesmerized, as each hard, deep thrust sent a visible jolt through Derek’s body, making his expression contort. Pleasure. Pain. Overwhelm. His brow furrowed, eyes squeezing shut for a second before snapping open again, wide and glassy. A low, desperate moan tore from his throat as Stiles angled his hips, grinding deep on the upward stroke. "Fuck, Stiles! Right there!"
"Yeah? Right fucking there?" Stiles snarled, his rhythm faltering, becoming more erratic, desperate. He slammed into that spot again. And again. The wet slap of his hips against Derek’s ass intensified. He stared down at the masterpiece of Derek’s ruined face – the sweat, the tears welling in the corners of his eyes, the streaks of Scott’s cum starting to dry and crack. "Your face… fucking covered… look how much he marked you," Stiles panted, his own control splintering. "You love it, don’t you? Love being used. Filled. Look how fucking hot you are."
Derek couldn’t form words, just a series of breathless, punched-out whimpers. His cock pulsed untouched on his belly, leaking steadily onto the mess already there. His ass clenched rhythmically around Stiles’ pistoning length, milking him. "Fuck! Derek!" Stiles roared, his body locking. He slammed in one last time, burying impossibly deep. "Taking it! Take it all, you fucking perfect hole!" His cock pulsed violently inside Derek’s slick, welcoming heat.
Thick spurts of hot cum erupted deep into Derek’s churning channel, mixing with Scott’s release. Derek’s body arched violently off the bed, a ragged scream ripping from his throat as the sensation of being filled again triggered his own untouched climax. Ropes of thick white spunk shot from his cock, splattering high onto his chest and chin, adding to the chaotic mess on his skin. His hole spasmed wildly, clenching and fluttering around Stiles’ pulsing cock as it emptied.
Stiles collapsed forward, bracing himself over Derek, his breath coming in harsh, ragged gasps against Derek’s sticky neck. He stayed buried deep, feeling Derek’s internal muscles milk the last drops from him. Beneath him, Derek trembled violently, utterly spent, his cum-smeared face a canvas of utter debasement. Scott’s low, satisfied chuckle sounded from the headboard.
