74. Fucking my sisters husband

Trigger Warnings: Infidelity, non-consensual voyeurism (making someone watch), psychological abuse, rough sexual play, choking, face slapping, and extreme explicit language.

    The living room of the Miller household was usually a place of sterile, suburban perfection. Tonight, it was a theater of cruelty. Lydia sat on the edge of the cream-colored sofa, her hands trembling as she watched her husband, Marcus, and her younger sister, Jade, share a bottle of expensive red wine.

Jade had always been the "problem" child-wild, impulsive, and deeply envious of everything Lydia possessed. For years, she had chipped away at Lydia's confidence, but tonight was the final blow. She was wearing a dress that was little more than a slip of black silk, her heavy tits practically spilling over the lace neckline every time she leaned in to whisper something in Marcus's ear.

"You look so tense, Ly," Jade purred, her eyes glinting with a predatory light. "Doesn't she look tense, Marcus? I think she needs to see what a real woman can do for her husband."

Marcus didn't look at his wife. He looked at Jade with a hunger that made Lydia's stomach turn. "She's always been a bit too fragile, Jade. Maybe she needs a lesson in how to please a man who doesn't want to play house anymore."

Lydia stood up, her voice a broken whisper. "Please... Jade, just leave. Marcus, stop this."

Jade laughed, a sharp, jagged sound. She stood up and walked over to Marcus, sliding onto his lap. She reached down and began to unbutton his trousers, her eyes locked on Lydia. "Sit back down, sister. You're not going anywhere. You're going to watch. Maybe you'll finally learn something."

Marcus grabbed Lydia's wrist, his grip like iron, and forced her back onto the sofa. "Watch, Lydia. Don't look away."

The air in the room became thick with a sick, heavy tension. Jade unzipped Marcus, and his cock sprang free-thick, dark, and already pulsing with a desperate, cruel need. Lydia let out a sob, covering her mouth with her hands, but Jade reached out and slapped her hands away.

"I said watch!" Jade hissed, her face inches from Lydia's.

Jade dropped to her knees between Marcus's legs. She didn't reach for him with her hands first; she leaned in and began to lick the length of him, her tongue darting out to taste the pre-cum. Then, she took the head into her mouth, her throat opening up to accommodate his massive girth. She was relentless, her eyes never leaving Lydia's tear-stained face.

"Look at her, Marcus," Jade muffled through the cock. "She's crying. She hates that I'm so much better at this than she is."

Marcus reached down and grabbed Jade's hair, yanking her head back and forth as he dictated the rhythm, forcing her to choke on him. Lydia's sobs filled the room, a low, broken melody of despair.

"Please... stop... Marcus, I love you," Lydia cried out.

"Shut up!" Marcus barked, his voice a primal growl.

He pulled Jade up and shoved her onto the coffee table, right in front of Lydia. He ripped the black silk dress away, exposing her body. Jade's tits were large and perky, her nipples already dark and hard. Marcus began to devour them, his mouth hot and demanding, his teeth grazing the sensitive peaks. He reached out and delivered a sharp, stinging slap to Lydia's cheek.

"See how she reacts, Lydia? She's a gusher. She's already soaking the table because your husband is touching her."

Jade reached out and grabbed Lydia's hand, forcing it onto her own breast. "Feel how hard my nipple is, Ly. Feel how much Marcus wants to breed me while you sit there like a ghost."

Marcus guided the head of his cock to Jade's pussy, the slick, dripping folds of her sex welcoming him home. “Ah, yes! Marcus you’re so big.” He drove into her with a single, grounding thrust that buried him to the hilt. Jade let out a long, shattered cry of triumph, her legs flying wide to accommodate him.

The rhythm was a frantic, wet percussion. Marcus was hammering into Jade, his balls slapping against her thighs, while Lydia sat inches away, forced to witness the destruction of her life.

"You like this, Jade?" Marcus hissed, his pace becoming a slow, punishing missionary rhythm. "You like taking what belongs to your sister?"

"I love it! I've always wanted him, Lydia! I've always wanted to feel him inside me while you watched!" Jade screamed, her body arching into every thrust.

Marcus flipped Jade over, forcing her into doggy style. He grabbed her hair and yanked her head back, his other hand finding her throat. "Look at your sister, Jade. Tell her what you're doing."

"I'm fucking your husband, Lydia! He's filling me up because you're too boring to keep him!"

Jade reached back and grabbed Marcus's ass, pulling him deeper. She was reaching her peak, the tension in her lower belly a white-hot spark. Lydia was a wreck, her head tossing back and forth, her voice a constant, low moan of "no, no, no."

"I'm close!" Marcus roared, his voice a primal, guttural sound of triumph. "I'm going to fill you, Jade! I'm going to put my seed so deep you'll never be able to wash it out!"

"Give it to me! Please, Marcus! Fill me! Breed me right in front of her!"

Marcus increased the pace, his thrusts becoming short, sharp, and desperate. He felt the white-hot spark of his climax beginning to bloom.

"I'm coming now! Beg for it, Jade! Tell me you want my hot cum inside your pussy!"

"I want it! Fill me! Oh god, please!"

He erupted. A hot, thick stream of cum hit the back of her pussy, his body shaking with the force of the release. He fired again and again, emptying every drop of his lust and his cruelty into her. Jade sobbed with pleasure, her head falling onto the table, her body heavy and sated.

Marcus eventually withdrew, the sound of his exit a sharp, liquid pop. He didn't offer Lydia a word of comfort. He just stood up, tucked himself back into his trousers, and reached for the bottle of wine.

Jade stayed on the table for a moment, the white cream of his release already beginning to trail down her thighs. She looked at Lydia and smiled-a dark, triumphant expression that held no mercy.

"Thanks for the show, Ly," Jade whispered, her voice returning to its cool, taunting tone. "Maybe next time you can join in. Or maybe I'll just keep him for myself."

Lydia didn't answer. She just sat there, her world in ruins, the scent of her sister and her husband's betrayal filling the room. The sterile, suburban perfection of the Miller household was gone, replaced by a raw, jagged truth that would never be forgotten.
