Massive thanks to my editor WokeUpOneDay for the effort and support he puts into my story. Please support him and his work.

The reason I swapped chapters one and two were because I wanted the reader to jump straight into the story, feel involved in the characters situation from the get go. I know it's a little different, but I thought it'd be fun.

With that out of the way, I hope you enjoy this chapter.

Chapter 3

Present day

Tobias threw stones into the water as he reflected on his thoughts. He knew thinking of his sisters sexually was wrong, but on the other hand, was he to be judged? It's difficult trying not to think of sex on a daily basis for anyone. But he was around his gorgeous sisters constantly in little to no clothing.

He found it difficult to imagine other women at this point. Whenever he had some alone time to relieve himself he would try to think of random beautiful women, but his mind would drift to his sisters every single time.

His forbidden thoughts only grew with every tease, touch and sight of naked flesh. It had begun to consume his mind entirely until he decided that maybe it wasn't as bad as he thought. If they really were trapped on this island for the rest of their lives, were they not to enjoy themselves? Should they try to remain innocent, even if they are never rescued? These questions went over and over in Tobias's mind as he walked the beach.

A soft voice came from behind him. "Are you ok, Tobi?"

"Sylvia. What are you doing out here?" asked Tobias, nervous that she might somehow know what he was thinking about.

"I heard you sneak out and wanted to check to see if you were ok. Having trouble sleeping?"

Tobias breathed a sigh of relief. He couldn't help but notice the cool breeze had caused Sylvia's nipples to stiffen and poke through the shirt. "Yeah, I just wasn't very tired and wanted some fresh air."

"Want some company?"

Tobias smiled at his sister. "Of course I do sis." Tobias kept looking at her face trying to avoid her chest, but failed a few times.

Sylvia walked beside her brother along the waterfront. "You know, if we had some variety of different food and a nice change of clothes then I wouldn't want to leave this island."

Tobias stopped dead in his tracks at her words. "What? Why? Wouldn't you want to get back to real life? Friends, family... a boyfriend?"

"I have those things here. You and Lexi are my friends and family. As for the boyfriend part, I wouldn't find a better man than you at home. Here I have you to myself, kind of. This island is just so pure and free. There's no war, no poverty and we look out for ourselves here. We aren't lazy, mindless zombies that care about social media or what the next big fad is anymore. It's freeing."

"I never really thought about it like that. I guess in a sense, we have more of a life than what some people do right now out there, in the world of technology and fame." Tobias looked out towards the never ending ocean. "Don't you want a life though? A man, kids, a house?"

"Of course I want those things at some point. Right now I want a shower, a cheeseburger and sex. But if we don't ever get off of this island then I don't want to waste my time not enjoying myself."

Tobias thought she said the word "sex" louder than the rest as he involuntarily stared at her nipples.

"Every single day I wish that we get off this island safe and sound, but I'm not going to waste time pining after my old life every moment of every day. I'm going to enjoy the freedom that this island gives us." Sylvia's words were spoken softly.

"All this time on the island I've been thinking of home and ways to get back there, while you've been opening yourself up to it and not letting the situation get you down." Tobias put his arm around his sister. "You're amazing, you know that right?"

Tobias felt Sylvia sink into him. "I just don't see why this island should put a downer on us. I mean, we made it here alive. Who knows how many people didn't on that flight."

A breeze blew by them off the ocean water which caused Sylvia to hold her brother closer. The chill caused her nipples to stiffen more and poke into his chest. Tobias noticed and couldn't help but look down at them.

Sylvia caught her brother staring at her bust and blushed. "Sorry. It's cold out here."

Tobias panicked as he realised he had been caught eyeing up his sister. "Uhh, oh sorry, I didn't mean to look." His mind went blank and had no excuse.

"Its ok, I don't mind. It's actually kind of flattering." Sylvia subconsciously pushed her breasts against Tobias more as she spoke. "Most attention I've had for a while."

They both laughed as another breeze blew by, Tobias moved his hand up to his sister's angelic face and tucked a strand of hair behind her ear. Sylvia felt her heart racing at the action and tried to calm herself down.

"We should get back to the camp. It's colder than usual tonight," Tobias spoke quietly, trying not to disrupt the mood.

Sylvia smiled as they began their climb back up to the camp. They remained close enough that her breast was still rubbing Tobias, which was beginning to have the usual impact on him. He picked up the pace in fear that his member would stand to attention.

Just as they reached the entrance to the shelter, Sylvia stood in front of her brother, stopping him from entering. "Tobi, you can talk to me. I will always be there to listen. I promise." With that, she leant up on tiptoes and kissed her brother on the lips with a quick peck. Then she retreated inside the shelter.

Tobias stood there for a few seconds completely stunned. The gorgeous brunette had just kissed him on the lips. Did it mean something? Or was he just over thinking it? Coming to his senses he decided to get to bed and try to sleep the thoughts away.

What he didn't realise was that Lexi had seen the whole thing.

Lexi had trouble getting out of her own head that night, and didn't get much sleep. She woke at the crack of dawn and decided to go for a long bath in the spring. Early on, when they first arrived on the island, they had dug a giant hole into the soil to make a small pond. They surrounded it with rocks to make it look more natural, hoping that it would be more relaxing when taking a bath. The water was cool but they had come to enjoy the fresh sensation run over their skin.

Lexi removed all of her clothes, relaxed into the waters and let out a moan as her muscles soaked in the fresh liquid. She ran through the memories of last night: Tobias and Sylvia had snuck out of the shelter and on their return, Sylvia had kissed her brother on the lips.

"They're having sex. There's no other explanation." At first Lexi found herself getting annoyed that they kept it a secret. But the more she thought about it, the more she envied her sister.

She began to imagine what might have happened between them that night and started cupping her heavy breasts. "Is it because mine are smaller than hers?" Lexi closed her eyes and imagined the act taking place before her: Tobias fucking Sylvia on all fours while she begged for more of her brother's hard cock. Lexi started to slowly pinch her nipples and lower one hand down to her snatch.

Vigorously playing with her clit, Lexi moaned her brother's name time and time again until her orgasm ripped through her body like electricity, giving her the hardest orgasm she had ever given herself. Lexi thought about what she had just done. She had played with herself while thinking of her siblings, but to her surprise she didn't feel guilty about it.

Lexi washed her curvaceous body down and dried off before returning to the camp. She was greeted by her sister trying to keep the fire going. "Hey sis. You're up early."

"Yeah. I woke up and went for a wash." Lexi replied with a vague and uninterested tone. "Is Tobi up yet?"

"Uh, no I think he's still asleep. Everything ok?"

Lexi didn't reply as she went to sit on the hill over looking the sea.

A couple of hours passed before Tobias woke up. Sylvia had the fire roaring and was preparing the morning meal. "Morning Syl. What's for breakfast?" he asked with a sarcastic tone.

"Fish, and for a change I thought I would add a touch of fish," Sylvia relied laughing.

Lexi joined her siblings around the fire for breakfast. It was eerily quiet for the first time since they arrived.

"Everything ok Lex? You seem quiet," asked Tobias.

"Am I not allowed to be quiet?" retorted Lexi.

"Wow! Hey now, I was only asking."

"Yeah well, whatever. I'm fine. I didn't sleep very well."

"Ohh that explains it. Well you better cheer up because me and you are going exploring."

The girls both looked at their brother confused.

"What? But we've already explored the island," Lexi asked.

Tobias had a smile plastered across his face. "Actually we haven't. There's still the area over the mountain. We haven't even seen the other side yet."

"It's not a mountain. It's just a big hill that we haven't bothered to climb yet. Besides, there won't be anything over there, just another beach and some coconut trees. What's the point?"

"Where's your sense of adventure Lex? It's unexplored territory." Tobias threw a small piece of wood at her. "For all you know there's a mansion with an unlimited amount of food behind that hill."

"Why isn't Sylvia going? Why do I have to?"

"Because I've asked you to. Now hurry up and eat your food before I do." Tobias smirked at Sylvia as he knew it would annoy their little sister.

"Ugh fine. But when we find nothing, I want you to apologise to me for dragging my ass up that hill for no reason."

"Deal."

They went back to their food and prepared for the journey ahead. Sylvia was ok staying behind because someone had to look after the fire, and when Tobias demanded something you usually did it.

Their trek up the hill was long and arduous. They had been walking for about an hour and were still a ways off the top. Tobias noticed his sister had been quiet the entire time so he decided he should stop somewhere up ahead and see what was wrong. They came across a small clearing surrounded by trees and he decided this was as good a place as any.

"Lex what's wrong? You're quiet and that's not like you," Tobias teased.

Lexi sat down a few feet away from her brother. "I'm fine. Just got a lot on my mind that's all." Lexi had been thinking all morning about bringing up last night to Tobias, but wasn't sure how to broach the subject.

"Wanna talk about it?"

"I don't know yet." Lexi looked towards her brother. He was sitting there looking powerful, fully aware of his surroundings like an animal. She began to imagine what it would be like to be thrown up against the tree by her brother and have her clothes ripped open. Her thoughts multiplied into scenario after scenario of her getting fucked by her older brother.

Tobias moved closer to his sister and put his hand on her bare leg. Lexi was wearing small shorts that stopped just below her ass that she wore on purpose to tease her brother that day. It had the desired effect as she caught him looking a couple times before he took the lead up the hill.

"Come on, you can tell me. I won't say anything to Sylvia if that's what you want."

"You're fucking her aren't you?" she blurted.

Tobias wondered if he heard that right. "What? Sylvia? No!"

"Yes Sylvia. I know you are!"

"Lexi, we are not fucking. She's my sister."

Lexi moved closer to her brother and stared straight into his eyes. "Right. So you two sneaking off in the middle of the night wasn't so you could get some alone time? Or perhaps I didn't see you two kiss outside the hut either?"

Tobias couldn't help but notice that her cleavage had become visible as she had leant in close to him. "That wasn't a kiss, it was a peck. We really aren't having sex, Lex." Tobias couldn't help but chuckle at his unintended rhyme.

Lexi suddenly bolted forwards, planting her lips on his in an instant of pure lust. Tobias acted on instinct and kissed back until their tongues danced around each others' mouths, exploring and delving into the first act of forbidden love.

Tobias suddenly shot up like a bolt of lightning. "We shouldn't have done that. That wasn't right."

Lexi stood up to look at her brother. He wouldn't return eye contact. "Lawfully it's not right, but that didn't feel wrong. I know you feel the same way I do," Lexi moved in front of her brother, pressing herself against him. "I've seen you looking at me. Every time I turn around or stand up you look at me, and not like a brother."

Tobias looked down into his gorgeous younger sister's blue eyes. "And that isn't right. Just because I can't control myself doesn't mean that you shouldn't either."

"But I want you Tobi. I cant help it. Every day and every night I see you, walking around without a shirt on, looking at us when you think we're not looking. I'm so fucking horny that I don't care what the world thinks! We're here right now, away from the world and its rules. Let's just enjoy it!"

Tobias was starting to crack. He didn't know if it was his sister's lustful face or the fact that her breasts were pressing into him, but he began to switch off his brain and go with it.

Lexi could see that he was at war with himself over the idea, so she decided to take the initiative and dropped to her knees. In one swift motion, Lexi had her hands around the elastic of her brother's shorts and had whipped them down to his ankles, bringing his boxers with them.

Down on her knees, staring at her brother's growing cock she realised it was bigger than any she had seen before. It wasn't massive but easily bigger than average. She moved like a flash and started pumping his thick rod in her small hands back and forth while looking up at her shocked brother.

Lexi had moved so fast that Tobias didn't have time to react. As soon as her hands were jerking his cock, he lost all control in that moment and just let was about to happen, happen. He looked down at his angelic sister's excited face as she started to lick the head of his cock.

"Oh my god Lexi!"

Lexi took her brothers now erect cock into her mouth, only as far as the ridge on his head and closed her plump lips around it as she stoked harder and faster. Her eyes locked onto her brother as she continued her attack.

Tobias was in heaven. His mind went numb as he saw his beautiful sister staring up at him while pumping his cock into her mouth. The thought of it was so wrong, but in that moment it only added to the erotic heights of his blowjob.

Lexi moved one hand down to her snatch and began to finger herself while sucking more and more of her brothers cock into her wanting mouth. Lexi was soaked. She had never experienced such a thrill before. As each inch of cock disappeared into her mouth, her fingers ran faster across her clit. She was getting closer to orgasm than she realised.

All Tobias could do was moan as his sister swallowed more of his cock. She easily took half of it in one go and then came out for air, before delving back down his shaft until it hit the back of her throat. Tobias could feel his orgasm nearing. It was quicker than he was used to, but having a beautiful young woman with a killer body sucking on your cock will do that to any man.

"Oh my god Lexi don't stop!"

She started taking her brother deeper into her mouth, hitting the back of her throat with every pump. The feeling caused her to moan, only making the sensation of her clit stronger. Lexi could tell her brother was close and got so excited about making him cum. Her hands jerked his dick faster and faster while her mouth never left his cock.

Lexi's fingers moved rapidly against her clit as she could feel her own orgasm threatening to consume her. Tobias moved his hands to the back of his sister's head as he began to pump his cock into her hot wet mouth.

"Oh fuck Lex, I'm going to cum!"

Lexi felt her own orgasm rip through her body as she sucked her brother's big dick into her mouth as far as it would go, and felt his body begin to spasm and release wave after wave of hot cum down her throat. Her moans were barely audible as she tried to swallow every drop of her brother's cum. She continued to pump his dick until he had to force her to stop.

Tobias hadn't noticed that his sister had been playing with herself until he saw her hand between her legs when he stumbled back. The thought excited him and caused his dick to jump. Lexi remained on her knees staring at her brother like a sex-crazed animal. She had a primal, lustful look to her that would drive any man into frenzy.

"Fucking hell Lex! That was insane!"

Lexi stood up off her knees and brought her finger to her chin where a stray glob of her brothers cum had escaped. She brought it to her mouth and licked her finger clean, all the while staring at her brothers half erect cock.

"Fuck!" was all Tobias could reply.

"That was so hot!" Lexi grabbed hold of her brother's vest and pulled him in close. "How was it for you?"

Something snapped in his brain at that moment. Tobias had just been sucked off by his youngest sister, and he enjoyed it. No, he loved it! He stood there towering over Lexi and smirked. Then in a split second he grabbed his sister's hips and spun her around so she was facing away from him. He then pulled her hips back into him so that her peachy ass was pressed up against his cock.

His strong hands began to roam over her body as he lightly kissed her neck. Lexi started letting out moaning sounds and crushed her perfect ass against his crotch.

"Oh fuck Tobi that feels so good."

Tobias moved his hands up her sleek body until he reached her bust. He grabbed hold of her mounds and squeezed them tight for the first time. Her breasts were impossibly soft and sunk around his fingers. Lexi's moans had become louder as her brother fondled her chest and started to suck on her neck.

Lexi was in a world of bliss as Tobias groped her body up and down. Every inch his hands played with became as hot as fire. "You're hands feel so fucking good brother."

Tobias didn't know if it was the word "brother" that got him going, or that he was caressing her tits like stress balls. Either way he was in heaven holding onto his younger sister's body. He lowered his hands until he grasped the bottom of her vest, started to pull it up over her head and tossed it to the ground.

Lexi reached her hands up and undid her bra while simultaneously walking forward and spinning to look directly at her brother. Tobias looked at her with a hungry, lustful stare. At this point he had thrown all hesitation out of the window. He knew what he wanted and he was about to take it!

Tobias stood there, his shorts down, his cock semi erect and his mind set to fuck. Lexi smirked at her brother as she removed her bra painstakingly slowly. He was about to see them, his first good look at his youngest sister's bare chest. The anticipation for the garment to drop grew. Lexi was enjoying herself and Tobias knew it.

The once-white bra dropped to the ground in slow motion revealing Lexi's perfectly firm breasts. They were round and full without any sag that Tobias thought would have been impossible unless he had seen it himself. Her areolas were bigger than a two pound coin and were a light pink that protruded out towards him. They were truly perfect and as Lexi bent down to drop her shorts and underwear, Tobias stood there in shock at the sheer beauty before him.

Tobias couldn't control his cock as it bounded back to life to strain at full mast.

"So Tobi. What do you think?"

Her brother remained speechless, completely lost for words he gazed at his sister's naked body. He stepped out of his own clothing and stood fully nude with his sister.

He couldn't wait any longer; her eyes glared at him with a passion so strong he couldn't help but bolt forward. His arms grabbed around her slim waist and lifted her off of the ground. Lexi squealed in surprise and wrapped her legs around his hips so that his cock was pressing into her entrance.
