Ruby's belly and breasts continued to swell as her pregnancy progressed, and both of the other girls were fascinated by the changes in her body, making any excuse to rub her belly and even feel her heavy, swollen tits. Although Sara continued to insist she didn't want to risk me getting her pregnant while we were on the island, you could see the envy, tinged with a little lust, when she touched her friend's pregnant body.
So it came as no surprise when, after two months of Davi shooting his massive loads all over every part of her body, one night Siobhan wrapped her long legs around her lover and made sure he couldn't pull out if he wanted to. "I want to feel your cum inside me," she moaned. "Fill me up with a big load of sperm." She knew full well Davi spoke no English, so it had to be for Ruby's benefit, or mine and Sara's. Or maybe she just lost control with that big cock buried deep inside of her.
Whatever the case, she soon got her wish, as Davi fucked her pussy raw before filling it with a copious load of sperm. When it was clear to him that she didn't object to being filled up with cum, he went right to work giving her more. Five times that night, he shot his load directly into her fertile womb. By the last time, she could barely stay awake, but she still murmured, "more... more... don't stop..."
For two weeks afterwards, Ruby had to be content with her fingers, as Davi focused on getting every drop of sperm his balls could produce as deep inside of Siobhan as possible. Once it was clear she wanted his baby — or didn't mind getting pregnant, at any rate — he was a man on a mission. And it was very quickly mission accomplished, as she missed her next period, and as far as I know didn't have another one as long as we were on that island.
I though, once the deed was one, Ruby would reclaim her man, but from that night forth, the two pregnant castaways took turns getting their pussies pounded night and day. Most nights, they both shared his bed and took turns riding his massive cock. Sometimes one girl would be too stretched out and sore and would take the night off, or Davi would pick one girl or the other to fuck all night long. But whatever happened, his tireless tool never disappointed — it seemed that, no matter how many times he had fucked, the Brazilian could always find some more sperm to add to either of the two wombs he had already impregnated.
Davi was basically the luckiest man on Earth. But I still thought of myself as the second-luckiest. I had two pregnant beauties walking around naked all day, every day. My gorgeous fianceé and I were fucking far more than we ever had in our old life, and island life seemed to agree with her. Sara was already trim and athletic to begin with, but between working on the island and swimming constantly, her lithe, muscular body never failed to arouse me any time I saw it. Which was often, as she hadn't worn a stitch of clothing for six months at this point. The constant sun and exercise had given her black skin an extra lustre, and what had already been a sexy body had become my idea of pure perfection.
The only thing that was missing, as far as I was concerned, was a sexy bulge in her tummy. Siobhan was showing nicely after only two months, and by that point Ruby's belly was ready to burst, and her boobs weren't far behind. As good as sex was with Sara, I fantasized about sucking milk from those big, brown titties, while rubbing my cock all over that pregnant belly of hers. Once I was able to have the same fantasies about Siobhan, it was only natural that I wanted Sara in the club too. But she always demurred, saying either she wasn't ready, or to wait until we were rescued. At that point, I didn't care if we ever left the island, but she was still hopeful.
Then Ruby had her baby. And everything changed again. The delivery went smoothly — again, I'm an optician, but I still knew enough to be able to hand Ruby a healthy baby girl, as Davi looked on, beaming. Her round, fleshy tits produced enough milk to feed a litter of babies, and little Joy was rarely far from her mother's breast, so she grew up strong right away. And Ruby had the rest of us to wait on her hand and foot while she recovered from childbirth, so mother and daughter couldn't have been happier.
The problem was Davi. With Ruby out of commission, he was focusing all of his considerable sexual energy on Siobhan. Which the Irish girl loved, for the first few days. She was instantly smitten with Ruby's baby, which just made her all the more excited about the one growing in her own belly. And that in turn made her all the more eager for the cock that had put it there.
But every woman has her limits. One particularly long night, Davi pounded her pregnant cunt from sundown to sunup, not sleeping more than half an hour before mounting her again. She could barely walk, even after sleeping it off, and that night when he came for her, she refused him.
Since the second night on the island, Davi hadn't been without a partner, and neither of his women had ever refused his cock. But Siobhan was sore and exhausted, and her eyes pleaded with him for a break. He stood over her, naked in the moonlight, erect cock jutting out from between his muscular legs, but he made no move towards her. He looked around the tent, unsure of what to do next, and his eyes met Sara. She did nothing to hide the fact that she was staring openly at his body, his mammoth cock in particular. He met her eyes, and for a long moment, they gazed at each other, until Ruby broke the silence with four fateful words.
"You want a turn?"
She nodded mutely, never taking her eyes from his. She stood up, and before she took a step towards him, she looked back at me. I know I should have stopped her, said know, taken her arm, something. Even now I wonder why I didn't at least say something. But I just looked her in the eyes, trying to read her thoughts. She gave me a pleading look, glancing over her shoulder at Davi and his waiting, rock-hard erection. I don't know why I did what I did. Maybe there had been so much sexual tension building up, with her watching him fuck every night. Maybe it was because Davi had taken the other two girls so often that it just seemed natural. Maybe it was because, after watching the other two getting fucked over and over again, and never failing to be incredibly aroused by it, I knew deep down how intensely erotic it would be to watch this muscular, well-hung stud taking my woman and fucking her deeper than I ever could.
I guess I'm still not exactly sure what my reasons were. But I stared into her eyes, and I very gently nodded my assent. I could see her tremble, as she took her first step across the sand towards him. There was a bright full moon that night, so I could see the beads of sweat running down her flawless black skin, as she walked away from me. Davi didn't make a move until she had crossed the shelter, and then reached a hand out and cupped her warm, waiting pussy in one hand. No kiss, no embrace — this was the first real physical contact the two of them had had. He slid two fingers inside of her, and it was clear how wet she already was. He used those fingers to pull her towards him, until her breasts were mashed up against his well-muscled chest. Her arms held him tight, one hand on his ass, and the other raking across his back. He placed his free hand on the back of her neck and kissed her, forcefully, tongue invading her willing mouth as his hand started to rub up and down against her slit, pushing two fingers in and out of her.
He broke the kiss, and a string of saliva ran down her cheek. She made no move to brush it away, instead moaning as his fingers pistoned in and out of her. He kissed her neck this time, and she cried out as he pushed four fingers inside of her, getting her ready for the real stretching out still to come. He moved his mouth to her breast, and she held his head there as he sucked on a dark brown nipple. She let out a yelp as he bit down on her breast, like a stallion marking his mare. He bit hard enough that the teeth marks were there for days afterward, but if anything, it turned her on even more, as she started bucking her hips against his hand.
He lowered her onto her back, legs spread, knees in the air, his fingers still inside of her, and I could see her chest heaving as she lay there, breathlessly awaiting penetration by his massive tool. But first, he kissed her again, hardly letting her come up for air, as he started ramming his hand into her cunt, harder than before. She cried out, "Oh God!" the second his tongue left her mouth, and she screamed out loud when he bit her other breast. She moaned as he started sucking her other nipple. "Please. I need it." However bad his English was, there was no mistake what it was she needed. "I need your cock inside me."
She looked over at me after she said that, maybe worried at my reaction. But my hand was stroking my dick, which she surely took as a sign of encouragement. She grabbed his cock with one hand, and started guiding it towards her waiting sex. But Davi made it clear he was in charge. He grabbed her by the wrist, and with one hand, pinned both of her hands above her head. He kept fucking her with four fingers, sucking on her gorgeous tits, while she cried out, "Don't tease me! Please! Please fuck me!"
I should have been horrified — the woman who had promised to be mine forever was begging, literally begging for another man's cock. I should have been, but I wasn't. My dick was as hard as iron, watching her lithe brown body heaving with pent-up desire. Finally, he decided she had suffered enough. He slid his fingers out of her wet snatch, and immediately lined his cock head up with her slit. She gasped as he pushed the bulbous head between the folds of her labia. As much as she must have been stretched out after having four fingers probing her roughly, Davi's cockhead was even thicker, and she gasped as he worked it inside her.
