Last time on Castaway Harem: Outside the storm continued to rage on. Eventually it was time to eat and the five of them were seated around the makeshift table feasting on the cooked pheasants, fish and fruits. The kid, now sitting in Yukiko's lap, was swiftly yet calmly shoving food into his mouth as if he hadn't eaten for some time. Nagisa took his hand gently and, with help from Yukiko, helped the boy eat more slowly so as to not eat too much and make himself sick. Rio and Kayano both smiled as they saw Nagisa and Yukiko help the newest member of their little castaway family. After dinner, Yukiko still had the young boy on her lap as she asked, "So do you think you could tell us what your name is, little one?"

"...Genji." the boy said timidly to the four adults as the storm outside slowly died down. Nagisa smiled and wiped some food off of his face as he said, "Well Genji, I'm Nagisa Shiota. These ladies are Rio Nakamura, Yukiko Kanzaki, and Kaede Kayano." Genji smiled and snuggled into Yukiko's chest. Rio rubbed his cheek and said, "Don't worry Genji, you Mommies and Daddy are going to take good care of you." That made Nagisa, Kayano, and Yukiko all blush at what Rio said to Genji. "Mommies?" Yukiko asked. Rio grinned and said, "Yeah you're like his mommy now, right? That means that Nagisa is his daddy. And because Kayano and I are also Nagisa's wives, that makes us his mommies too." Nagisa blushed hard as Genji looked at Yukiko and said, "Will you be my mommy?" Yukiko blushed before smiling and said, "Of course, sweetie." Genji smiled and hugged her closely.

Outside the storm had finally passed though it was still a little dark from the clouds. Nagisa decided it was time to get to work on impregnating the other two girls as he took Kayano's hand and asked, "Ready?" To which she just blushed and nodded her head lightly. Nagisa and Kayano then walked out of the hut and down the beach a ways so Genji couldn't hear them. Kayano leaned on Nagisa and smiled, she was ready to be the next woman to bear a child for Nagisa. Nagisa held her close until they were a good distance away from the hut before he kissed her deeply. Kayano moaned and wrapped her arms around his neck and pulled him deeper into her lips.

Their hearts unchained their undeniable lust and love for one another. Nagisa and Kayano continued to make out right there on the beach, their hands traveling all over each other. It took only for seconds for the two to get nude, Nagisa wrapping his arms around the future mother of his child and holding her tightly while he continued to kiss her.

Sliding down Nagisa's naked front, Kayano licked her lips while she stared at her lover's manhood, her eyes lighting up with hunger. Her fingers wrapped around his thick length, marveling at his large size. Already Nagisa's tip was leaking pre-cum and it made her womanhood tingle with want. She brought her lips to his tip but didn't start to gobble his cock right away. Instead, Kayano put her hands on his hips to prepare herself before she took a deep breath through her nose. In one swift motion she plunged her face down onto the hard cock, stuffing her mouth all the way to the back of her throat and kept going. A choked gag came from her as her chin touched his balls, the scent of Nagisa overpowering her nose as it pressed into his pelvis.

Nagisa almost went cross eyed when Kayano began to fuck her face, stuffing every inch of his veiny girth into her orifice. His hands instinctively went to her head, digging his fingers into her while trying to maintain himself. But he became a shaking mess from the utter vacuum that was Kayano's mouth, her head bobbing back and forth, gagged moans escaping her. Unable to stop himself, Nagisa started to match her movements with his own thrusts, fucking her face hard as if he was trying to knock her up through her mouth. With a loud cry that echoed across the sea, Nagisa threw his head back and gave the young woman the treat he'd been holding back.

Kayano suffered a mini-orgasm when hot cum shot down her throat, her stomach hot as man seed filled it. She reached down and started to touch herself, her womanhood dripping onto the sands with her arousal. When Kayano pulled away, nursing a sore throat from the hard face fucking, she licked her lips at the sight of his throbbing cock still hard. "Fuck me…" she said, eyes glazed over with lust.

The girl turned around and got on all fours, sticking her ass up in the air. "Fuck me, Nagisa! Fuck me as hard as you can!" she pleaded. "Let's make Genji lots of brothers and sisters!"

Grinning, the blue-haired Nagisa eagerly mounted his lover, hotdogging his cock between her asscheeks to tease her a little. When Kayano moaned for more, he gladly gave it to her. Rearing his hips back, the young man speared the woman's pussy with his clamhammer, bottoming out her pussy and stretching it wide.

Nagisa gripped the greenette's hips and started to pound her pussy as hard as he could. His hips were a blur, driving his cock in and out of her fast. Kayano saw stars from feeling the huge tip hammer away at the door to her womb, demanding entrance to let him fertilize her tender soil. "Cum in me!" she shouted, bucking into his thrusts, her ass jiggling like jello as it smacked his thighs. "Breed me!"

"What was that?" teased Nagisa, reaching around to cup Kayano's tits. "I couldn't hear you."

"Breed me!"

"Louder."

"BREED ME, YOU FUCKING STUD!" howled Kayano, her body shaking and aching to receive his cum. "CUM LOTS IN MY WOMB!"

Leaning down, Nagisa pressed his chest against her bare, sweaty back, clutching her tightly like he was a dog breeding his bitch; an apt comparison. Just when Kayano could take no more, Nagisa felt his balls start to swell and his manhood's tip started to pulse inside her. "I'm cumming!" he grunted into her ear.

"Yes! Cum in me, Nagisa! Knock me up!"

Her wish was granted. Nagisa let out a masculine growl, pushing his cock as deep as it could go inside the young woman. A large wet rush filled Kayano's womanhood, the girl smiling from ear to ear as she was creampied hard. Her arms and legs started to shake while trying to support both their weights. The sky was spinning while she suffered her own orgasm, her pussy becoming nothing more than a leaking faucet of sexual juices spilling out of her.

Nagisa stood up on his knees, wrapping his arms around the girl and pulling her up with him. His hands reached down and started to rub Kayano's stomach, already imagining himself fucking her with a big pregnant belly. Turning her head, Kayano showed she still had the spark of lust still in her eyes. "You know, we should really make sure I'm pregnant, Nagisa…"

"Damn straight." Nagisa kissed her, gripping her hips while beginning to move inside of her, his cock still erect and ready for more.

Several hours passed as the two continued their mating. After several more rounds of fucking on the beach like horny rabbits, Nagisa carried the girl over to a soft patch of grass to lay her down on. However, Kayano had become like a Succubus, intent on draining every last drop of spunk in Nagisa's balls and making sure it all went into her womb. First they fucked in missionairy, then in the sitting position. Then Kayano decided she needed a turn on top.

Putting her hands on his shoulders, Kayano shoved him onto the ground. Leaning backwards, the naked greenette put her hands on the young man's knees before she started to bounce up and down on his cock, her face twisting with pleasure while feeling his manhood churn the hot cum already stuffed in her pussy. "Fuuuuck! Your baby…give me your baby!" she demanded, sweat pouring off her naked body as she rode Nagisa like there was no tomorrow.

Before Nagisa could blow his load, he let his masculine instincts take over. Wrapping his arms around her waist, the young man leaned forward and grabbed the girl's legs, putting them on his thin shoulders and pinning Kayano to the ground in the mating press. With all the strength he still had in his body, Nagisa slammed into her pussy as hard as he could. "Here…it…cums!" he grunted, his eyes going blank as he finished off Kayano's womanhood with one last burst of cum.

Kayano's face turned into pure ahegao, her pussy squirting with delight while she received her lover's seed. If this didn't get her pregnant, then she didn't know what could.

And with that last giant orgasm Nagisa had emptied all that was left of his balls inside of Kayano. They both collapsed from the combined ecstasy and exhaustion, both were Breathing heavily. He remained on top of her, his member slowly softening but also remaining inside of her. Kayano, panting with her tongue out and without the energy to talk, thought to herself, 'Oh my God, that was awesome! Wow! What a sturdy penis! What a strong stud! Nagisa, I really love you so much…' And they fell asleep together as Nagisa's thick seed flooded out of Kayano's still plugged up cunt.

The next morning Nagisa woke up still on top of her. His member was still inside her but was now rock hard again with morning wood. He gave her sleeping mouth a soft kiss which quickly grew ravenous, waking her up. She immediately reciprocated and then felt his boiling hot seed once again shooting inside of her making her flinch. She pulled away and said, "Well aren't you eager, even after doing it so much last night." Nagisa smiled down at her, put his hand on her cheek and said, "It's perfectly natural for a guy to be hard in the morning". Kayano then snaked her arms around his shoulders, leaned up dangerously close and seductively said, "Well then, I guess we'll have to take care of that, won't I?" She then captured his mouth in another wild and hot kiss and they proceeded to fuck like wild animals with such energy that it was almost as if they hadn't done it for hours on end the night before.

Back in Japan, Meg was puking in her bathroom toilet as Yuma checked on her. Yuma rubbed her back and asked her if she wanted him to get anything for her and she said, "Yeah, an end to this." Yuma chuckled and said, "Well when we found out you were pregnant, we knew this would be a problem." Meg nodded her head and sighed before there was a knock on the door. Yuma walked over and opened it to see Hinata, both hands resting on her 3 month baby bump, with her husband Hiroto next to her.

"Hey thanks for coming, you guys." Yuma said as he ushered the couple in. Hinata walked over to the bathroom and smiled at Meg who was holding her head over the toilet and said, "Ah Morning sickness, the one thing I don't like about being pregnant." Meg looked at her and said, "Then why are you pregnant a lot? I mean what is this, kid number seven you're on now?" Hinata nodded her head and said, "I know, but I just can't help it. We just can't keep our hands off each other. He loves my pussy and I love his penis. And I'm addicted to having his scalding hot penis milk shot into me." Meg just turned back to the toilet and grimaced in second hand embarrassment as Hinata continued to gush about the sex she and her husband were having. "And his balls are absolutely loaded, like every time we've gotten pregnant on the first try." Meg looked at her and said, "Hinata, I love you like a sister. But can you please, STOP!"

Hinata saw Meg's face and stopped talking about it.
"Sorry, so how are things with you besides puking into the toilet every morning, any cravings?" Hinata sweetly asked

"You mean besides Yuma's hard dick in and out of me, it seems I enjoying eating Peanut Butter Oreos with Strawberry topping and I also have cravings for cheeseburgers

"That's better than what I have cravings for, Pickles and ice cream," Hinata sighed. Meg looked like she was about to throw up again before pausing and thinking about it.

"Any kind?" Meg asked honestly

"They go good with Vanilla, Caramel and surprising Mint Chocolate Chip" Hinata said

"I may have to try that," Meg said as Yuma looked at Maehara who shook his head fast.

Meanwhile, back on the island, Nagisa and Kayano walked back to the hut when Yukiko, Rio, and Genji came out. Yukiko immediately covered Genji's eyes. Nagisa and Kayano blushed and got dressed to spare Genji's innocence. Nagisa then kissed Rio and said, "Well it's done, last and not least is you Yukiko." Yukiko Smiled and said, "Please take good care of me Nagisa." Nagisa smiled and nodded before kissing Yukiko passionately. After pulling away Yukiko crouched down to look Genji in the eye, ruffled his hair and said, "I'm going to be away with Daddy for a bit. Do you think you can behave for Mommy Rio and Mommy Kayano while I'm gone?" Genji nodded his head and hugged his two moms while Yukiko and Nagisa walked out of the hut in search of a good spot to make love.
