The months on the island since they’d discovered each other sexually had been like something from another world. The twin siblings no longer lived a life that resembled their old one. No longer professional athletes on their way to college, they were now like wild things.
The two of them so browned by the sun, his body so hard and muscular. His hair had grown long and golden, like a thick lion’s mane about his neck. The boar’s meat added to their diet so that he’d grown bulkier with muscle, and they knew enough of how to dry and store it so that it lasted them a long time with their fish and fruit.
He’d even discovered a method of tracking the boars and finding the delicious tubers they ate, thereby adding something else to their diet.
It was hard work when it needed done, but it rarely did. It was easy to supply for them, left them with so much free time. Free time to rut like beasts, mostly.
Though on a rare moment he instead guided her through the jungle to the beach shore. She’d not been there in a while, since her pregnancy had gotten so advanced. But lingering in the grotto by the lagoon had worn on her nerves, he could tell. So though she’d never ask, he took her for a walk, the two nude lovers–and siblings–walking side by side. The spear in Zach’s hand as he led her along protectively. There were, after all, other boars on the island.
“Careful of the shells on the beach,” he reminded her in his deep voice as they neared the edge of the tropical trees.
She knew. She was the one that told him about it, but she didn’t argue or tease him. Not anymore. Instead she just moved closer to his, her arm entwined with his body as her green gaze went everywhere. He could tell she was happy, even if she didn’t speak much anymore. She didn’t need to.
Not with how well he understood her.
Her long hair was almost to her nude bottom, her body having lost some of its athletic tone since she’d swollen so large with child. Her free arm coddled that large, firm flesh and felt the baby move within her, its foot pressing against her hand. She didn’t fret about it any longer.
As soon as they came to the beach he turned her towards him and smiled down so full of self-confidence. “Here we are, sis,” and there was deep, tender affection in his eyes despite his stern look, his calm control.
He stuck the end of the spear into the sand and put both hands upon her. He squeezed one of her milk-engorged breasts and stroked over her smooth belly. “This is going to be the most beautiful, perfect child ever to grace the earth,” he declared with certainty, so smugly confident in the fruits of their incestuous loins as his own prodded up to life against her thigh.
They’d been out there a full year, and she knew his body so well. Her hand fell to his cock and gripped it so perfectly. He’d taught her everything she needed to know about pleasing him, spent hours coaching her and ma
king her into his image.
The perfect woman.
Her breast leaked its milk over his hand, dribbling down the digit as she stroked him. “It won’t be long,” she murmured as her swollen womb brushed his abs.
There was no shame, no hesitation. Not anymore. The island was theirs, the ##world was theirs. And thanks to his insistence, they had reclaimed some innocence, some ability to live on it freely and without hesitation to indulge their baser instincts.
“Not long before I have to fill you with another,” he boasted confidently as she so expertly handled his cock. The constant fucking of nearly nine months had given them plenty of time to master so much of each other’s bodies.
With a husky groan he bent down and put his lips to her free teat, suckled at it blatantly in the mid-morning sun. He was unbothered by drinking his sister’s milk, he’d made that clear before. Claiming it as another fruit of his ownership of her that he’d take as he saw fit.
That soft little “Ah,” the way her nipple hardened against his tongue spoke of her own lack of concern. At first she’d protested, ashamed and afraid, but he enjoyed it, and just like everything else, she had succumbed and learned to take her own pleasure in it. Her breasts were so large, bigger even than they had been prior to her pregnancy, and they sat atop that pregnant swell in such a suggestive manner.
Her nipples were a darker brown from the sun, from the pregnancy, and stood out so prominently as they hardened, leaking that sweet milk onto his tongue. It was so perverse, so wrong, yet they didn’t care. They’d lost their shame together, and they had no desire to learn it again.
Zach squeezed and groped her tit and ass cheek so lewdly as he drank. It was only when that skillful twist and pump of his thick cock became so tantalizingly pleasurable that he could no longer ignore it that he had to stop. He licked about his lips and groaned with satisfaction, “C’mon. I need to dump a load in you before we go any further,” and his hands had already begun to gently but forcibly guide her body to the sand to her hands and knees.
She was less graceful, her balance set off, but that only worked better for him. She was so much more pliable and agreeable as her knees spread, her milk spilling into the sand as her breasts swayed beneath her body. She was already soaking wet for him, her pussy lips glistening beneath her round ass.
Her blond hair spilled over her bronzed cheeks and her breathing was so much louder, even against the crashing of the waves along the shore.
Zach never grew tired of that sight. Of seeing his sister bent over and willingly presenting herself for him. Her puffy pussy lips so swollen and red from his frequent use of her. Even as she’d swollen with his incestuous child he’d not ceased taking her again and again each day, his young male virility knowing no bounds.
Though even he, as strong and savage as he’d become, played a bit gentler with her as he slid that thick, engorged cock into her moist lips. Such a deep, unrestrained groan filled the air as he took hold of her hip and hair, using the long strands like reins to control her. “Can’t wait for you to pop so I can fit more of my dick back in you,” he husked before beginning the motions of his hips, fucking her openly upon the beach with a tug of her hair. The fullness of her womb didn’t let as much of his length into her as he used to be able to get in.
Yet she still moaned with that wanton need, her toes curling into the sand. They were perpetually nude, always fucking, yet it had only gotten better. He knew just the places to hit to remind his sister of why she wanted to please him. To remind her of her place.
It was bliss to take over her life, to make her his and be able to play her body with such ease. He knew her inside and out, and yet they never tired of one another. Well, he never tired of her.
Zahra’s moan cut through the air as he tugged her hair again, that sound like a drug as her cunny squeezed him, sending tendrils of ecstasy up his length.
Sweet bliss inside his own sister, that was the only way he could describe it. He held her tight as she gripped him so exquisitely. That tight clench prompted him to increase his pace, the bucking grown a little harder, a little too hard as he bumped into her deeply, painfully. But he groaned with such satisfaction, his dick swelled with such hunger inside her. “That’s it, sis. My sweet lil’ cum dump,” he crooned affectionately in that harsh manner of his. “My personal sister slut,” and he punctuated his degrading words with a slap of her ass.
She used to whimper, and protest. She used to hate those cruel words, but instead they simply made her moan louder, her back arching as he spanked her. He could see the blood rush to her flesh, reddening it in the shape of his large palm, marking his sister physically.
