The following morning, the tropical sun beat down with a relentless intensity, turning the sand into a shimmering white furnace. Sherri, her sundress clinging to her damp curves, sent Marie off into the jungle to forage for wild fruits and tubers, leaving her alone with Brian.
“Come on, honey,” Sherri murmured, her voice humming with a hidden vibration. “Let’s go back to the wreck. I think there are some more linens and tools in the lower compartment that we can use for the shelter.”
Brian followed her, his muscles still tight from the previous night’s exertion. As they descended into the belly of the ship, the air became stagnant and heavy, smelling of brine and old oil. The lower compartment was a cramped, dim space, the tilted floor making every step a precarious effort. As they reached the center of the hold, Sherri suddenly stopped and turned, her back against a bulkhead, effectively blocking the only exit.
Brian stopped, confused. “What is it, Mom?”
Sherri’s gaze was predatory, her eyes scanning his athletic frame before locking onto his. A slow, knowing smile spread across her lips. “I saw you two last night, Brian. Under the palms.”
Brian froze, his face flushing a deep crimson. He opened his mouth to stutter an excuse, but Sherri stepped closer, the scent of her musk filling the small space.
“Don’t bother lying,” she whispered, her voice dropping to a sultry purr. “I’m not angry that you’re fucking your sister. I’m only upset because I wasn’t invited to join the fun.”
Before Brian could process the words, Sherri dropped to her knees. With a swift, decisive motion, she reached out and yanked his shorts down to his ankles. His cock, already reacting to the shock and the sudden proximity of his mother, sprang free, hard and pulsing in the dim light.
Sherri didn’t hesitate. She wrapped her hand around the base of his shaft, her grip firm and experienced, and slid her mouth over the head of his cock. Brian let out a strangled gasp, his head hitting the bulkhead behind him.
Unlike Marie’s tentative, eager movements, Sherri was a master of her craft. She used her tongue to swirl around the sensitive rim of his glans before sucking him deep into her throat, creating a powerful vacuum that made Brian’s toes curl. She worked him with a rhythmic, punishing intensity, her cheeks hollowing as she drew him in, her tongue flicking against his frenulum with pinpoint precision.
Brian’s breath came in ragged, desperate hitches. He gripped her shoulders, his fingers digging into her skin as he felt the pressure building. The sensation was overwhelming—far more intense than anything he had ever experienced. As Sherri increased the pace, swirling her tongue and sucking harder, Brian hit his breaking point.
He let out a loud, guttural groan, his entire body shuddering as he erupted. Thick ropes of cum shot into Sherri’s throat, and she didn’t pull away, swallowing every drop with a look of triumph. The orgasm was so violent, so all-consuming, that Brian’s knees buckled, and he slumped against the wall, his eyes glazing over, nearly passing out from the sheer sensory overload.
Sherri pulled back, licking her lips with a satisfied smirk. She gently pushed him toward a pile of salvaged mattresses. “Just stay here and rest, sweetheart,” she whispered, kissing his forehead. “I’ll finish the work.”
By the time Marie returned from the jungle, clutching a handful of wild berries and roots, the sun was beginning to dip. She found Brian fast asleep on a mattress near the shelter, his chest rising and falling in a deep, exhausted slumber. Sherri was nearby, tending to a crackling fire, the aroma of grilled fish filling the air.
“Where’s Brian? Why is he asleep already?” Marie asked, her voice breathy and curious.
Sherri didn’t blink. She turned to her daughter, her expression calm and honest. “I caught him in the lower compartment, Marie. I told him I knew about you two, and then I gave him a blowjob he’ll never forget. I think I broke him.”
Marie’s eyes widened. She took a step back, her face a mixture of shock and a flicker of jealousy. “You ... you did what? Mom, that’s...”
Sherri stepped forward, her movements fluid and graceful. She reached out, her fingers softly stroking Marie’s cheek, pulling her closer. “Shh,” she whispered. “It’s okay, baby. There’s plenty of love to go around on this island. And I think it’s your turn to be spoiled.”
With a sudden, assertive movement, Sherri reached for the hem of Marie’s denim shorts and pulled them down, stripping her daughter naked in a few quick motions. Then, Sherri shed her own dress, her ample, heavy breasts swinging free, her nipples hard and dark.
Sherri pushed Marie down onto the soft sand just outside the shelter. She didn’t waste time, sliding her body between Marie’s legs. Sherri flipped her daughter over, lifting her hips to expose the pink, wet folds of her pussy and the tight circle of her ass.
