Mom, son sister

Robert is balls deep in his mother when his sister walks in. Short, sharp and intense

"Fuck, Mom, you're so tight," Robert groaned, his hips pistoning forward with desperate urgency. The bedroom smelled like sweat and sex, the rhythmic slap of skin against skin muffled only slightly by the tangled sheets beneath them. His mother, Lisa, arched her back, her fingers digging into his shoulders as she gasped, "God, baby, don't stop—right there, right there—"

Her cunt was slick around him, gripping his cock like a vise as he drove into her deeper, harder. Robert's breath came in ragged bursts, his teenage body wired with reckless need. Lisa's thighs clamped around his waist, pulling him impossibly closer as she moaned, her nails scraping down his spine.

The door creaked open with a slow, deliberate sound, cutting through the symphony of their panting. Heather stood frozen in the threshold, her knuckles white where they gripped the doorknob. Her gaze darted between her brother’s glistening cock, still buried deep inside their mother, and Lisa’s flushed face, lips parted mid-moan.

Robert froze, his body rigid with shock, but Lisa—Lisa only sighed, rolling her head lazily toward her daughter. “Heather, honey,” she purred, her voice thick with arousal, “close the door or come in. Don’t just stand there gawking.” Heather’s breath hitched, her cheeks flushing crimson as her eyes lingered on the wet, swollen lips of her mother’s cunt stretched around Robert’s shaft.

“I—I want—” Heather stammered, her voice cracking. Robert finally found his words, though they came out strangled: “Jesus, Heather, get the fuck out!” But Lisa shushed him, reaching down to stroke his thigh reassuringly. “Baby, be nice,” she murmured before turning back to Heather. “Come here, sweetheart. Let’s talk.”

Heather’s legs moved before her mind could protest, stepping into the room like she was in a trance. The door clicked shut behind her. Lisa shifted beneath Robert, her hips lifting slightly, making him groan as her cunt clenched around him. “You like watching, don’t you?” Lisa asked, her fingers trailing up Heather’s arm. Heather swallowed hard, her pulse hammering in her throat, and nodded.

Robert’s cock twitched inside Lisa as Heather took another hesitant step forward, her breath shallow and uneven. Lisa’s fingers tightened around his thigh, nails digging in slightly—whether from arousal or surprise, he couldn’t tell. Heather’s gaze was locked on the glistening mess where her brother disappeared into their mother, her tongue darting out to wet her lips. “I want to taste you,” she whispered, the words trembling in the air between them.

Lisa’s hips jerked involuntarily, clenching around Robert as a shudder ran through her. “Oh, fuck,” she gasped, her voice ragged. Heather didn’t wait for permission. She dropped to her knees beside the bed, her fingers trembling as they brushed Lisa’s swollen folds, slick with Robert’s thrusts. The moment Heather’s tongue flicked out to trace the seam of her mother’s cunt, Lisa cried out, her back arching off the mattress. Robert groaned, his rhythm stuttering—Heather’s mouth was hot and eager, her tongue lapping at the mingled wetness with a desperation that made his balls tighten.

“Jesus Christ,” Robert gritted out, his hips bucking forward on instinct. Heather moaned against Lisa’s flesh, her hands gripping her mother’s thighs to hold her open. Lisa’s fingers tangled in Heather’s hair, tugging her closer, urging her deeper. The sight of his sister’s face buried between their mother’s legs, her tongue working in time with his thrusts, sent a brutal surge of heat through Robert’s body.

Then Heather pulled back just enough to meet his eyes, her lips shining. “Fuck me while I eat her,” she demanded, her voice husky. Robert didn’t hesitate. He slid out of Lisa with a wet pop, earning a whimper from both women, and dragged Heather up by the hips. She scrambled onto the bed, her knees sinking into the mattress as she pressed her mouth back to Lisa’s cunt. Robert lined himself up behind her, his cock dripping with their mother’s arousal, and shoved into Heather in one brutal thrust.

Lisa gasped, her fingers tightening in Heather’s hair as her daughter’s tongue plunged inside her. The sensation of Heather’s moans vibrating against her clit while Robert pounded into her from behind was overwhelming. Lisa’s thighs trembled, her cunt pulsing around nothing, aching to be filled again. “Oh my god,” she choked out, her hips jerking against Heather’s mouth. “You—you two—fuck—”

Robert’s hands dug into Heather’s hips, his thrusts growing erratic. Heather’s fingers curled into Lisa’s thighs, her tongue circling her mother’s clit with feverish precision. The room was filled with the sounds of skin slapping, wet sucking, and ragged moans—a symphony of debauchery that none of them had ever imagined. Lisa came first, her body seizing as Heather swallowed her release. Heather followed moments later, her cunt clenching around Robert as she screamed into Lisa’s flesh. Robert lasted only a heartbeat longer, his hips slamming forward as he emptied himself inside his sister with a guttural groan.

Panting, sweat-slicked, and spent, they collapsed onto the bed in a tangled heap. Lisa’s fingers traced lazy patterns down Heather’s spine while Robert pressed a kiss to the back of her neck. Heather turned her head to nuzzle against Lisa’s thigh, her lips brushing the damp skin there. “Didn’t know you wanted this,” Lisa murmured, her voice thick with satisfaction. Heather smiled against her mother’s flesh. “Neither did I,” she admitted. Robert chuckled, his breath warm against Heather’s shoulder. “Now you do,” he said, and the unspoken promise hung heavy in the air between them.

The morning sun filtered through the curtains, casting golden streaks across the rumpled sheets. Lisa stretched lazily, her body deliciously sore, and rolled onto her side to watch her children sleep. Heather was curled against Robert’s chest, his arm draped protectively around her. Lisa smiled, her fingers brushing Heather’s hair back from her face. Heather stirred, blinking sleepily up at her. “Morning,” Heather whispered, her voice rough. Lisa leaned down to kiss her forehead. “Morning, sweetheart,” she murmured. Robert groaned, rolling onto his back and dragging Heather with him. “Too early,” he grumbled, but his hand slid possessively down Heather’s thigh. Lisa laughed softly, her fingers trailing down Robert’s chest. “No such thing,” she teased. Heather grinned, shifting to straddle Robert’s hips. “She’s right,” she said, her fingers wrapping around his already hardening cock. Robert groaned again, but this time, it was a sound of surrender. Lisa leaned in, her lips brushing Heather’s as her hand joined her daughter’s. “Let’s start the day right,” she whispered.

Heather’s breath hitched as Robert’s fingers tangled in her hair, guiding her mouth back down to Lisa’s cunt. The taste of her mother was intoxicating—sweet and musky and utterly addictive. She lapped hungrily at Lisa’s folds, her tongue dipping inside to gather every drop of Robert’s release. Lisa gasped, her hips jerking as Heather’s tongue worked her over with shameless precision. Robert groaned behind Heather, his cock throbbing against her backside. “Fuck, Heather,” he muttered, his fingers tightening in her hair. Heather moaned around Lisa’s clit, her fingers gripping Lisa’s thighs to hold her open. Lisa’s back arched, her fingers clutching at the sheets as Heather’s tongue circled faster, harder. “Oh god,” Lisa gasped, her thighs trembling. Heather pulled back just enough to meet her mother’s eyes, her lips glistening. “Like it?” she asked, her voice thick with satisfaction. Lisa nodded, her breath coming in ragged bursts. “Yes,” she whispered. Heather grinned, lowering her mouth once more just as Robert’s cock slid home inside her with a single, brutal thrust.

Lisa’s cry was lost in the cacophony of moans and gasps that filled the room. Heather’s nails dug into Lisa’s thighs as Robert pounded into her from behind, his rhythm relentless. The sensation of Heather’s mouth on her cunt while Robert fucked her was overwhelming—Lisa could feel every stroke, every lick, every shuddering breath. Her orgasm crashed over her like a tidal wave, her body convulsing as Heather drank her in. Heather followed moments later, her cunt clenching around Robert as she screamed against Lisa’s flesh. Robert lasted only a heartbeat longer, his hips slamming forward as he emptied himself inside Heather with a guttural groan. They collapsed onto the bed in a tangled heap, their bodies slick with sweat and spent. Lisa’s fingers traced lazy patterns down Heather’s spine while Robert pressed a kiss to the back of her neck. Heather turned her head to nuzzle against Lisa’s thigh, her lips brushing the damp skin there. “Didn’t know you wanted this,” Lisa murmured, her voice thick with satisfaction. Heather smiled against her mother’s flesh. “Neither did I,” she admitted. Robert chuckled, his breath warm against Heather’s shoulder. “Now you do,” he said, and the unspoken promise hung heavy in the air between them.

Lisa’s fingers carded through Heather’s hair, her touch gentle. “You okay?” she asked softly. Heather nodded, her lips brushing Lisa’s thigh. “Yeah,” she whispered. Robert’s hand slid down Heather’s side, his fingers tracing the curve of her hip. “Good,” he murmured. Lisa smiled, her fingers trailing down Heather’s spine. “We should shower,” she said, her voice lazy with contentment. Heather groaned, pressing her face into Lisa’s thigh. “Too tired,” she mumbled. Robert chuckled, rolling onto his side and pulling Heather against him. “Later,” he agreed. Lisa sighed, stretching languidly. “Fine,” she conceded, her fingers trailing over Heather’s shoulder. Heather smiled, her eyes drifting shut. “Love you,” she murmured. Lisa kissed her forehead. “Love you too,” she whispered. Robert pressed a kiss to Heather’s temple. “Love you both,” he said, his voice rough with emotion. They lay there, wrapped in each other, the silence warm and comforting. The sun climbed higher, casting golden light across their entwined bodies, but none of them moved. There was no rush, no urgency—just the quiet certainty of what they were, and what they would be.

Lisa’s fingers traced idle circles on Heather’s hip, her touch feather-light. Heather sighed, her body boneless with satisfaction. Robert’s breath was warm against her shoulder, his fingers tangled in hers. Lisa watched them, her heart full. She’d never imagined this, never dreamed it—but now that it was here, it felt inevitable. Heather turned her head, her lips brushing Lisa’s thigh. “What are you thinking?” she asked softly. Lisa smiled, her fingers brushing Heather’s hair back from her face. “Just how lucky I am,” she murmured. Heather grinned, her fingers tightening around Robert’s. “Me too,” she whispered. Robert pressed a kiss to Heather’s shoulder. “Me three,” he said, his voice thick with affection. Lisa laughed softly, her fingers trailing down Heather’s spine. “Cheesy,” she teased. Heather giggled, turning her face into Lisa’s thigh. “You love it,” she mumbled. Lisa kissed her forehead. “I do,” she admitted. Robert groaned, rolling onto his back and dragging Heather with him. “Too much talking,” he grumbled, but his fingers traced Heather’s ribs with unmistakable tenderness. Lisa laughed, stretching out beside them. “Fine,” she conceded, her fingers trailing over Heather’s hip. Heather sighed, her eyes drifting shut. “Perfect,” she murmured. And it was.
