Becca watched it all from inches away. She saw the absolute devotion on her brother's face, even as he was used as a furniture. She saw the powerful flex of John's ass as he hammered into Mary. She felt the sticky warmth cooling between her own thighs. Her hand drifted down, her fingers sliding through the mess John had left, collecting it. A bizarre, voyeuristic compulsion took her.
John's pace became frantic, his thrusts losing rhythm. "Gonna fill you too," he grunted into Mary's ear, his teeth grazing her shoulder. "Gonna pump you full."
"Yes!" Mary shrieked, her body tightening. "Do it! Claim me!"
As John slammed home one final time, his body shuddering with his second release, Mary's orgasm ripped through her. She ground down violently on Andy's face, her thighs clamping around his head, her cries muffled by her own ecstasy.
They stayed locked together for a long moment, panting. Then John pulled out, his cock dripping anew. Mary, breathing heavily, lifted herself from Andy's bruised mouth. She turned, a wicked smile on her face, and looked at the wreck of her boyfriend.
"Now," she panted, pointing to Becca's glistening, used pussy. "Clean her. Clean my man's seed from your sister. Lick it all up."
Andy didn't hesitate. He scrambled, driven by a deep, masochistic need to obey. He pushed himself up and lunged toward Becca, his head diving between her legs. His tongue, already coated with Mary, now sought the thicker, saltier flavor of John's cum mixed with Becca's arousal. He lapped at her swollen folds, chasing the escaping rivulets, sucking and cleaning with a fervor that was both grotesque and worshipful.
Becca gasped, her sensitive flesh twitching under the rough, desperate strokes of his tongue. The taboo was absolute, the humiliation complete. She looked over Andy's bobbing head and saw Mary, now kneeling before John, taking his softening cock into her mouth to clean him.
Becca's fingers tangled in Andy's hair, not gently, but with a possessive yank that made him groan into her slick heat. The vibration of his muffled sounds sent fresh jolts through her overstimulated clit, her hips bucking involuntarily against his devouring mouth. He slurped noisily, tongue delving deep into her stretched entrance, scooping out globs of John's thick semen that clung to her inner walls. The metallic tang mixed with her own tangy juices, and Andy swallowed it down greedily, his cheeks hollowing as he sucked harder, drawing out every drop like a starving animal.
Mary watched with hooded eyes, her lips still wrapped around John's spent shaft, nursing it back to life with slow, deliberate swirls of her tongue. She popped off with a wet smack, strings of saliva and residual cum connecting her mouth to his glistening head. 'Look at him go,' she murmured to John, her voice husky from her recent screams. 'What a cum-slut, tongue-fucking his own sister's sloppy seconds. Pathetic, isn't he?' John chuckled darkly, his hand stroking Mary's hair as he glanced down at the scene. Becca's thighs quivered around Andy's ears, trapping him in place, forcing him to inhale the musky scent of her arousal while his nose pressed against her pubic bone.
'Deeper, Andy,' Becca commanded, her voice breathy but edged with cruelty, emboldened by the power shift. She ground her pussy against his face, smearing the mess across his lips and chin, marking him as hers. 'Taste how your sister's cunt got ruined by another man's cock. Lick up every bit of that superior seed.' Andy's cock twitched painfully between his legs, leaking pre-cum onto the floor, his humiliation fueling a twisted arousal. He obeyed, probing her with his tongue until it ached, lapping at the sensitive rim of her hole where John's girth had left it puffy and raw.
John's dick hardened fully in Mary's grip, veins bulging as she pumped it lazily. 'Enough foreplay,' he growled, pulling Mary to her feet by her arm. He spun her around, bending her over the edge of the bed so her ass jutted out invitingly, still flushed from his earlier pounding. 'Time to share the wealth.' He positioned himself behind her, but his eyes locked on Becca and Andy. 'You, furniture boy—get over here and hold her cheeks open. Make sure I can see that pretty pink asshole while I fuck her again.'
Andy pulled back from Becca's pussy with a gasp, his face shiny and streaked with fluids, lips swollen from the abuse. He crawled on hands and knees to Mary, his movements servile and eager. Kneeling behind her, he gripped her firm ass cheeks, spreading them wide to expose her dripping slit and the tight, puckered ring above it. Mary's hole winked at him, a bead of John's previous load trickling down toward her perineum. 'Like this, sir?' Andy whispered, voice trembling with shame, his breath hot against her skin.
'Wider, you useless prick,' John snarled, slapping Andy's hand away before guiding his cock back into Mary's welcoming pussy. He thrust in with a single, brutal shove, making her cry out and arch her back. The force rippled through her body, her tits swinging heavily as John set a punishing rhythm, his hips slapping against her with wet, obscene sounds. Andy's fingers dug into her flesh, holding her open like a speculum, watching John's thick shaft piston in and out, coated in fresh cream. Each plunge displaced more of the cum inside her, forcing it to bubble out around his girth and drip onto Andy's wrists.
Becca, left momentarily empty, slid off the bed to join them, her body still humming from the aftershocks. She positioned herself beneath Mary, face up, and latched onto one of her swinging breasts, sucking the hard nipple into her mouth with a hungry pull. Milk-white skin bruised from earlier bites, she bit down just hard enough to make Mary hiss. 'Mmm, taste so good when you're getting railed,' Becca mumbled around the flesh, her free hand snaking between her own legs to rub circles over her throbbing clit. The room filled with the symphony of flesh on flesh—John's grunts, Mary's moans, Andy's whimpers as he fought to keep his grip amid the shaking.
Mary reached down, grabbing Becca's hair and mashing her face harder against her chest. 'Suck harder, you greedy bitch. Pretend it's the cum you're craving.' Then, with a wicked twist, she looked back at Andy. 'And you—don't just hold me open. Lick his balls while he fucks me. Worship the sack that's about to unload in your girlfriend again.' Andy's face burned crimson, but he leaned in without protest, extending his tongue to lap at John's heavy, swinging balls. The skin was salty with sweat, the orbs tight and full as they slapped against Mary's clit with every thrust. He tongued them reverently, tracing the seam, even daring to suck one into his mouth gently, feeling it pulse against his lips.
John groaned at the added sensation, his pace faltering for a second before he redoubled, fucking Mary like a man possessed. 'Fuck, yeah—feel that, slut? Your boyfriend's rimming my nuts while I breed you.' Mary's walls clenched around him in response, her second orgasm building fast. She released Becca's hair only to shove two fingers into the younger woman's mouth. 'Suck them clean first, then finger my ass while he does.' Becca complied, hollowing her cheeks around the digits, tasting the faint remnants of whatever Mary had touched earlier. Then she withdrew them, slick with spit, and reached up to circle Mary's exposed asshole, pushing one finger in knuckle-deep.
The intrusion made Mary buck wildly, her body caught between the dual penetrations. 'Yes—finger-fuck my shithole, Becca! Make me cum like the dirty whore I am!' Andy, still lapping at John's balls, felt the telltale twitch—the cock in Mary swelling even thicker. John roared, burying himself to the hilt as he erupted, jet after jet of hot cum painting her insides white. Mary shattered around him, her pussy spasming, squirting a gush that splashed onto Andy's face and chest. Becca's finger was trapped in the clenching ring, milking it as Mary rode the waves.
As they collapsed in a heap, John pulled out with a pop, his cock flopping semi-hard against Andy's forehead, smearing it with their combined mess. 'Your turn to clean up again, cuck,' John ordered, stepping back. Andy, dazed and dripping, dove in once more, his tongue plunging into Mary's overflowing pussy, sucking out the fresh load while Becca watched, fingering herself to the sight. The cycle of degradation spun on, binding them all in a web of taboo ecstasy, no end in sight.
Mary's body trembled in the aftermath, her pussy still fluttering around Andy's invading tongue as he slurped up the overflowing cum John had just deposited. Thick strands of semen clung to his lips, mixing with her squirted juices that dripped down his chin onto the floor. He probed deeper, his nose buried in her soaked folds, inhaling the pungent mix of sex while his own cock throbbed uselessly, denied any relief.
John stepped back fully now, his muscular frame glistening with sweat, cock hanging heavy and slick between his legs. It bobbed with residual twitches, coated in a sheen of Mary's cream and his own release, the head still flushed purple from the exertion. 'On your knees, Mary,' he commanded, voice rough and satisfied. 'Suck me clean. Show your cuck how a real woman services a man.'
Mary slid off the bed with a languid grace, her thighs slick and quivering. She dropped to her knees before John, eyes locked on his prize, and wrapped her hand around the base, lifting it to her parted lips. Her tongue flicked out first, tracing the underside from balls to tip, lapping away the sticky residue. Then she engulfed the head, sucking hard, her cheeks hollowing as she drew out the last drops trapped in his slit. She bobbed her head slowly, taking more of his length into her throat with each pass, gagging slightly when the girth stretched her jaw. Saliva bubbled at the corners of her mouth, dripping down his shaft as she cleaned every inch, humming in approval at the taste of their combined flavors.
Becca, her fingers still circling her own clit, watched with hooded eyes, the sight reigniting the fire in her core. She crawled forward on all fours, positioning herself behind John, her breath hot against his ass cheeks. 'Let me help,' she murmured, voice thick with lust. Her hands gripped his firm glutes, prying them apart to reveal the dark, musky cleft. Without hesitation, she leaned in, tongue extended, and licked a broad stripe up his crack, savoring the salty tang of sweat and faint traces of earlier exertions. John grunted in pleasure, his cock jerking in Mary's mouth as Becca's tongue zeroed in on his asshole, circling the tight ring before pushing inside. She rimmed him with fervent laps, spearing her tongue as deep as she could, feeling the puckered muscle clench around the wet intrusion. Her nose pressed into his perineum, inhaling his masculine scent while she devoured him, alternating between probing licks and sucking kisses on the sensitive skin.
Andy knelt there, transfixed, his face a mess of fluids, cock leaking steadily as he witnessed the dual worship of the man who had claimed them all. John's hips rocked slightly, fucking Mary's face in shallow thrusts while Becca's rimming sent shivers up his spine. 'That's it, sluts,' he growled, hand fisting Mary's hair to guide her deeper. 'Clean your king.' Mary's throat worked around him, swallowing convulsively, until John's cock emerged shiny and spotless, no longer dripping.
Finally, John pulled away, turning to face the group with a smug grin. Mary and Becca rose together, their lips glistening—hers from cock, hers from ass. They turned to Andy, who sat back on his heels, eyes wide with humiliated anticipation. Mary grabbed his chin first, yanking his mouth open, and plunged her tongue inside, forcing the flavor of John's cleaned cock onto his taste buds. She kissed him messily, saliva and faint cum traces swapping between them, her teeth nipping his lower lip hard enough to draw a whimper.
Becca followed, shoving Mary aside playfully before sealing her mouth over Andy's. Her kiss was deeper, more invasive, her tongue thrusting to mimic the rimming she'd just performed, coating his palate with the earthy, musky essence of John's asshole. She ground against his thigh as she did it, leaving a wet smear from her pussy, making him taste the forbidden while feeling her heat. Andy moaned into her mouth, his body shuddering, the ultimate degradation sealing the night's depravities.
They broke apart, leaving Andy gasping, lips swollen and flavored with John's dominance. The room fell into heavy silence, broken only by ragged breaths, the air thick with the scent of sex and submission. No words were needed; the bonds of their twisted desires held them fast, promising more in the shadows of taboo.
