The storm hit without warning, tearing our yacht apart and dumping what remained of us onto a jagged, palm-fringed island. Me, my wife Elena, and our twenty-year-old son Marcus washed up together, clothes shredded, bodies bruised but alive. We had no radio, no supplies, just the three of us and the endless ocean. At first we huddled in a cave, clinging to each other for warmth as rain lashed down. Elenas full breasts pressed against my chest through her torn blouse, nipples hard from cold, while Marcus stared at the floor, trying not to look.
By the third day hunger drove us to explore. We found another survivor, a broad-shouldered fisherman named Rico who had been marooned for weeks. He was raw and direct, built like a bull, with dark eyes that lingered on Elenas curves every time she bent to gather fruit. That night around the fire he told stories of the island, his voice low and rough. Elena laughed too loud at his jokes, her hand brushing his arm. I watched, a strange heat building in my gut even as jealousy twisted it.
Rico didnt waste time. On the fifth night he pulled Elena aside while Marcus slept. I followed at a distance, heart pounding, and hid behind thick ferns. Rico had her against a tree, his big hands ripping open what was left of her shirt. Her tits spilled free, heavy and pale in the moonlight. He sucked one nipple hard, teeth grazing, and Elena moaned like she hadnt in years. Fuck, your husbands right over there, Rico growled, shoving his hand down her shorts. You gonna let me wreck this married pussy while he watches? Elenas answer was a desperate whimper and her legs spreading wider.
I should have stopped it. Instead my cock hardened instantly, throbbing against my palm as I stroked in the shadows. Rico yanked her shorts down and spun her around, bending her over a fallen log. His thick cock slapped against her ass, already leaking. He drove into her in one brutal thrust, balls deep in my wifes soaked cunt. Elena cried out, pushing back to take every inch. The wet slap of skin on skin echoed through the trees. Rico fucked her like an animal, gripping her hips, pounding so hard her tits swung and her juices ran down her thighs. Tell me whose slut you are, he demanded.

Yours, Elena gasped, fuck me harder, make my husband hear.
I came in my hand without touching her, watching Rico fill her, his cum overflowing and dripping from her stretched hole. When they finished, Elena looked straight toward my hiding spot, eyes glazed with lust and something darker. She knew. From then on it became our new rhythm. Every night Rico claimed her in front of me, sometimes with Marcus nearby pretending to sleep but clearly listening. Elena rode Ricos cock on the beach, her ass bouncing, begging him to breed her while I jerked off helplessly. She made me lick his load from her pussy afterward, whispering how much wetter it made her to see me broken and hard.
Weeks blurred into raw, filthy routine. Rico took her mouth while I watched, spit and precum running down her chin. He bent her over our shelter and fucked her ass for the first time, her screams of mixed pain and pleasure carrying across the water. Marcus eventually joined the circle, stroking himself as his mother got used like a fucktoy, but he never touched. The power stayed with Rico, and the humiliation stayed mine. Elena came harder each time she locked eyes with me mid-thrust, telling Rico how my tiny cock could never compare.
One stormless morning we spotted a distant ship. Rescue was coming. Elena kissed Rico one last time, slow and deep, then turned to me with a satisfied smile. Were going home, she said, but this island stays with us. My cock twitched again at the promise in her voice. We boarded the rescue boat as a family, carrying the secret of how a shipwreck turned me into a permanent cuckold who couldnt stop craving the next time shed spread for another man. The ocean stretched ahead, but the real wreckage was inside me, and I was already hard thinking about it.
