The news hit like a physical weight. A long weekend at the family cabin in the mountains. Their parents called it "family bonding," a chance to solidify the new union away from the distractions of the city.
To Damien and Sera, it sounded like a death sentence. It meant forced proximity in a rustic house with thin walls, shared meals, and almost zero privacy.
The night before the trip, the air in the penthouse was thick with a frantic, suffocating tension. They both knew the risks of the weekend ahead, and the pressure made them feral.
Damien didn't knock when he entered his master suite to find Sera waiting for him. He didn't speak. He simply crossed the room, his eyes dark with a manic hunger, and grabbed a silver-grey silk tie from his dresser.
He shoved her toward the headboard, his movements rough and efficient. He caught her wrists, winding the silk tight until they were pinned to the heavy wrought-iron bars. He didn't want her moving; he wanted her trapped.
"You think you can handle three days of playing the good little sister?" he rasped, his breath hot against her ear as he spread her legs wide, anchoring them against his hips.
He went at her like an animal, determined to ruin her before the world tried to make them "normal." He started with his tongue, a slow, torturous lapping that sent jolts of electricity through her until she was sobbing against the headboard. Then his fingers took over, rhythmic and brutal, stretching her until she was begging for more.
When he finally entered her, it was with a heavy, bottoming-out thrust that made the bed frame groan. He edged himself for almost an hour, pulling back every time he reached the brink, forcing her to stay in that agonizing state of near-climax.
"Say it," he commanded, his hand tightening around her throat as he banged her. "Call me what I am while I fuck you into this mattress."
"Brother... please... Damien, please," she moaned, her head lolling back, her eyes glassy with a mix of shame and pure, unadulterated lust.
"I'm going to fuck you in that cabin while Mom and Dad sleep right down the hall," he promised, his voice a low, vibrating growl as he pounded deep into her. "And you're going to stay quiet, Sera. You're going to swallow every scream while I fill this pussy again and again. Do you hear me?"
The mental image of the risk, of the thin walls and their parents' presence, was the final spark. Sera shattered, her body going rigid as she squirted around his cock in a violent, rhythmic tremor.
Damien followed a heartbeat later, a guttural roar leaving his chest as he emptied a massive, hot creampie deep inside her.
Afterward, they lay in the ruins of the sheets, sweaty and completely spent. The weight of reality began to sink in: the long drive, the shared meals, the constant act of pretending they didn't know the taste of each other's skin.
In a rare, uncharacteristic moment, Damien leaned over and pressed a lingering kiss to her forehead. He pulled back, his eyes searching hers in the dim light.
"This trip is going to be hell," he muttered.
Sera looked up at him, a slow, filthy smile spreading across her lips even as her body began to hum with a fresh wave of need.
"Or," she whispered, "it'll be the best kind of heaven."
