Chapter 10: A Threesome in the Guest Room
The door opened. Marcus stepped inside, followed by Jessica, who closed it behind them with a soft, definitive click. The room felt different to him now—smaller, the air already used and warm, carrying a scent he recognized as Sarah’s arousal mixed with their father’s cologne. Sarah was sitting up on the bed, the quilt pulled around her shoulders, her blonde hair tangled. Their eyes met. Something profound and unspoken passed between them—a shared, dizzying knowledge.
James gave his son a steady look, clasped his shoulder briefly, and left without a word.
The three of them were alone.
Jessica smiled, a quick, reassuring flash of teeth. She was calm where Marcus was vibrating with nervous energy. “You okay?” she asked him, her voice low.
“Yeah,” Marcus said, his voice cracking. He cleared his throat. “Just… a lot.”
“It’s simpler than you think.” Jessica turned to Sarah. “And you? You look beautifully ruined.”
Sarah blushed, but held her gaze. “I feel… good.”
“I know you do.” Jessica’s attention swung back to Marcus. She approached him, her movements fluid. Without ceremony, her hands went to his belt. He stood rigid, letting her undress him, his eyes darting to Sarah, who watched with a quiet, focused intensity. When his cock sprang free, already half-hard from adrenaline and the charged atmosphere, Jessica nodded appreciatively.
“Good,” she murmured. Then she sank to her knees.
Marcus gasped as her mouth, hot and wet, engulfed his balls. She took one, then the other, into her mouth, sucking gently, her tongue circling the sensitive skin. Her hand wrapped around the shaft of his cock, pumping him slowly. The dual sensation—the shocking, tender suction on his sac and the firm stroke of her hand—made his legs tremble.
“Fuck,” he breathed, tangling his hands in her dark hair.
Jessica hummed, the vibration traveling straight through him. She worked him with methodical precision, her mouth leaving his balls to lick a thick stripe up the underside of his cock before taking the head past her lips. She sucked, hard, her cheeks hollowing.
It was too much, too skilled. The coil in his gut tightened violently.
“Jess, I’m gonna—“
He came with a choked cry, jets of cum spilling over her hand and onto the worn wood floor. His hips jerked uncontrollably. She stayed with him, milking him through the pulses until he was soft and sensitive in her grip.
But she didn’t stop.
She leaned in, licking his slit, cleaning the last drops from his cock with a flat, slow stroke of her tongue. Then she took his spent balls back into her mouth, suckling softly, her hand stroking his shaft with a relentless, gentle rhythm. To his shock, he felt a stir again, a dull throb of renewed interest as she coaxed blood back into the soft tissue.
“How?” he whispered, amazed.
“Practice,” she said, her voice a husky rasp. She rose, guiding him backward until his calves hit the bed. “Sit.”
He sat. Sarah shifted closer to him, the quilt falling away. He saw the faint, pearlescent streaks on her back, the mark of their father. It should have felt strange. Instead, it felt like a part of the ritual, a badge. Jessica straddled his lap, her knees pressing into the mattress on either side of his hips. She reached between them, guiding his newly-hard cock to her entrance. She was already soaked.
She sank down onto him in one fluid, breathtaking motion.
“Oh, Christ,” Marcus groaned, his head falling back. She was incredibly tight, hot, and slick. She began to move immediately, setting a fierce, rising rhythm, her hips rolling and pumping. Her breasts, freed from her shirt, bounced with each descent. He gripped her hips, his fingers digging into her flesh, trying to match her pace.
Sarah watched for a moment, her green eyes dark. Then she moved. She knelt on the bed behind Jessica, her hands spreading the older woman’s ass cheeks apart. Marcus stared, mesmerized, as his sister leaned forward and pressed her face into the exposed cleft.
Jessica cried out, her rhythm stuttering. “Yes… fuck, Sarah, just like that.”
Sarah’s tongue emerged, pink and sure. She licked a long, slow stripe from Jessica’s clit, over her perineum, to the tight, clenched pucker of her asshole. She circled it with the tip of her tongue, then flattened it, lapping at the sensitive skin. Jessica moaned, grinding down harder on Marcus’s cock.
“Deeper,” Jessica begged, pushing back against Sarah’s face.
Sarah obeyed. She pressed the point of her tongue against the resistant ring of muscle, working it insistently until it yielded. She speared her tongue inside, fucking Jessica’s ass with short, plunging strokes.
The sounds in the room became a raw symphony: the wet slap of Jessica’s body on Marcus’s thighs, the slick sounds of Sarah’s mouth working, the ragged gasps and choked profanities. Marcus could feel every flutter of Jessica’s cunt around his cock, could see the intense concentration on his sister’s face as she serviced the other woman. The sight of it—Sarah’s innocence wholly abandoned to this carnal act—drove him wild.
“You like that?” he grunted up at Jessica, his thrusts becoming harder, more driving. “You like my sister eating your ass while I fuck you?”
“God, yes!” Jessica shrieked, her body beginning to tense. “I’m gonna come! Don’t stop!”
Her inner muscles clamped around Marcus’s cock in a violent, rippling spasm. She threw her head back, a raw, guttural cry tearing from her throat. The convulsions of her orgasm triggered his own. He slammed up into her, holding her hips down as he erupted, pumping his seed deep inside her in hot, relentless pulses.
They shuddered together, collapsing into a panting heap. Sarah slowly withdrew her tongue, her chin glistening. She didn’t retreat. Instead, she continued to lick gently, cleaning Jessica’s swollen, well-used flesh, lapping up the mingled fluids that dripped from her.
Jessica finally rolled off Marcus, lying on her back between the twins, spent and smiling. Sarah curled beside her brother, her head on his shoulder. Their skin was damp, salty. The lamp flickered, casting the scene in a wavering, golden light.
No one spoke for a long time. The house around them was silent now, the whispers and creaks having faded into the deep night.
Marcus finally looked at Sarah, really looked at her. Her eyes were heavy-lidded, peaceful. “You okay?” he asked, echoing Jessica’s earlier question.
Sarah nodded, nuzzling into his shoulder. “More than okay.” She paused. “You?”
“Yeah.” He meant it. The nervous energy was gone, replaced by a profound, bone-deep exhaustion and a strange, expansive calm. He reached over and took her hand, intertwining their fingers. They lay there, the three of them, listening to each other’s breathing even out.
Jessica finally stirred, sitting up. She leaned over and kissed Sarah softly on the mouth, a kiss of thanks and solidarity. Then she did the same to Marcus. “You both did wonderfully,” she said, her voice soft.
