The Island of Three Ch. 02

Sylvia returned from the spring with a fresh few bottles of water to boil. They had found plenty of washed up trash along the beach, bottles included.

Tobias stood and walked to help his sister. "You shouldn't be carrying so much. You're supposed to be resting."

"Oh come on, I'm fine. I just want to help you guys."

"I know, but you have to rest so you can get back to full strength. I don't know if you remember, but you were unconscious when we arrived!" Tobias couldn't help but appreciate the help, even though he knew she was still weak.

"Syl, why don't we get our bikinis on and relax for a bit?" Lexi asked with excitement.

During the week they had been working non-stop to try and get the place liveable, as well as find food and build a shelter. She hadn't even thought about relaxing until now.

"Wait, what? Bikinis? Where did you find bikinis?" asked Tobias. Sinfully his mind went wild at the thought of the two busty babes in swimwear. He then scolded himself for thinking it.

"Umm we brought them with us bro. Its ok to relax a little, isn't it?" Lexi looked like she was pleading.

"Yeah sure, why not? Seeing as we haven't got any place better to be, go wild," he responded with a small dose of sarcasm in his voice.

The girls squealed and ran into the shelter to change. Tobias didn't really mind, but the thought of relaxing while they should be trying to get off of the island felt strange to him. He then also realised he might be being too harsh, and decided to just let them have this.

Moments later, Tobias's sisters returned to where their brother was standing. He turned around to see them in all their glory. Sylvia was in a jet black matching top and bottoms while Lexi's was a light blue. They looked to small for the women as their breasts threatened to explode out of the thin fabric. Tobias couldn't believe his eyes as he marvelled each sister individually for a time.

Tobias's eyes had gone wide, and Lexi wondered why until she remembered what her brother had told her just before they found the island. She knew this was the perfect opportunity to tease him. "Pretty sure it's wrong to be ogling your sisters there Tobi." Lexi then grabbed Sylvia's arm, rubbing the side of her bust briefly. "Like what you see?"

Tobias had no words. He knew he shouldn't be looking at his sisters this way but he found it so alluring and couldn't control his actions.

"Lexi. Stop teasing him. He's not ogling us, he's just mad at how little we're wearing," Sylvia said, not thinking it possible for her brother to be enjoying her body that way.

Tobias was glad Sylvia had brought that up as he didn't have a good excuse for why he was suddenly out of breath. He immediately started frowning in disapproval. Their brother thought he was safe, but little did he know Lexi wasn't falling for it.

"Sure, whatever. I'm going to enjoy the sun for a bit. Try not to let your jaw hit the floor when I walk away bro."

Lexi turned around and headed for the beach, all the while putting more of a pump in her steps causing her hips to sway. It had the ideal effect as Tobias couldn't help but watch. Sylvia was oblivious, keeping the thought of it being annoyance at what they were wearing.

Sylvia followed her sister to sunbathe for the rest of the day, taking with her some of the lotion they had brought with them. Tobias had to shake his head at his own thoughts and began to tidy up the camp, as a means to distract himself.

At the beach, Lexi thought about what had just happened. She enjoyed the feeling of winding up her brother, and had been doing it since she could remember. As her mind drifted between the times she had annoyed him, it dawned on her: she actually quite liked the feeling of her own brother looking at her as a woman rather than a sister.

Sylvia had joined Lexi on the beach and handed her sister the lotion. She had laid down looking in the opposite direction and seemed oblivious to the world.

Lexi began to spread the cool liquid over her nearly naked body, starting with her legs and working her way up her curves. She made her way up to her breasts and started enjoying the feeling of her hands roaming her body. She hadn't realised that she was thinking of Tobias running his masculine hands over her body, ripping off her tiny bikini and taking her right then and there on the beach.

Lexi shot her eyes open as she realised of what she was thinking. "What are you doing?! He's your brother!" she thought as she nervously looked to her sister. Luckily she was still looking away and hadn't noticed a thing.

Lexi reached her hand down to her pussy and realised she was getting wet. "Oh my god!" The overwhelming urge to play with herself was almost too much, but she managed to gain some form of control and chase the naughty thoughts from her mind.

The girls relaxed and let the sun soak their skin for the first time since reaching the island. And for the first time, they forgot that they were marooned on a tropical island. Tobias had decided to relax as well. So after he was finished tidying the camp, he joined them on the beach in his swim shorts, much to his sisters' delight.

After a few weeks the siblings had managed to gather more resources for their survival. With zero contact with the outside world, they decided to try and increase their way of living. Finding a fishing net, plenty of scrap and plastic bottles, they had now made their temporary base a little more comfortable and liveable. The net had helped drastically as they had actually fish to eat which massively helped with their energy.

The shelter had been upgraded with comfier beds, more shelter with the odd chance of rain and a somewhat working door. It was actually a few vines of ivy draped over the entrance, but it helped keep the light out. It was beginning to get to the point where the siblings realised they might be there for longer than they expected, and decided to keep hope but not leave life's qualities aside.

Even after a few weeks on the island, they hadn't searched the entire land. It was bigger than they first thought and had, at best, viewed about half. Over the next few weeks they decided it might be best to explore as much as possible to maximise the food source. Living on fish and coconut would get boring quickly and they knew it.

Sylvia had fully recovered at this point and was now working just as hard as the others. Cleaning clothes, cooking the fish and fetching the water were now easy for her to do, and she didn't complain once.

Lexi knew how to annoy her sister. Even though they all had a very limited amount of clothes to wear, Lexi still ended up borrowing Sylvia's clothes. It usually ended up in some form of light wrestling between the two. That was something Tobias would enjoy watching, but would break up eventually.

His sisters were in the process of fighting over one of his shirts to wear, as it was the "comfiest one", or so they said.

"Lex, its my turn with that one!"

"You had it last week. It's mine this week. Besides, it looks cuter on me, doesn't it Bro?" Lexi posed for her brother, standing to the side and poking her bum out.

Tobias immediately started gawking at his sexy sister. Then looked away and scolded himself internally. "How about I wear it? It is my shirt after all."

"What? No way, you only wear boxers to sleep. I want it," Lexi replied with a pout.

"Fine. But Sylvia gets it tomorrow." Tobias noticed Sylvia was annoyed at this but couldn't do anything as Tobias tended to be in charge and it was his shirt.

"Yay! Thanks Tobi." Lexi bounced over to her brother and wrapped him in an embrace, purposefully pushing her breasts into his strong chest.

"Uhh, yeah sure thing. Now I need my beauty sleep. You two are so draining." Tobias removed his clingy sister, while secretly enjoying the softness of her bust, and headed towards his bed.

Sylvia sadly sighed, grabbed a different one of Tobias's shirts and went over to her bunk. For Tobias, this was one of the best parts of the day, as both girls removed their clothes and slipped into his shirts.

He watched as Sylvia turned her back to him, removed her shirt and unclasped her bra. Even though her back was turned to him, Tobias could still see the sides of her boobs bounce about as she would shimmy the shirt on over her head.

Lexi had caught her brother watching Sylvia a few times now and wondered whether or not he watched her do the same. The thought always got her going and she often had dreams of her and Tobias taking things too far. Once Sylvia had gotten into the shirt and lay down to sleep, Lexi did the same as her sister.

Lexi's lust had taken over, and she wanted to give her brother a show. She started taking off her shirt, but instead of turning around like she usually did, she stayed facing forward. Removing her shirt, she was left exposed with only her bra and trousers on. Tobias had instantly noticed and started watching like it was some kind of porno. Lexi pretended not to notice she was showing herself off to her siblings and slowly bent down, bringing her trousers with her.

As she bent down, she exposed her impossibly large cleavage and now stood there in just her underwear. Tobias was awestruck. He couldn't help but watch the show as his member began to rise to the occasion.

Sylvia hadn't taken much notice until her sister started to reach for her clasp and undo her bra. Both siblings were watching, one in shock and the other in anticipation as Lexi removed the garment. Tobias was now at full mast as he was seconds away from seeing his busty younger sister completely topless.

Lexi turned around just as she pulled her bra off. Tobias missed it by a split second and was only rewarded with a side view of her perfect naked form.

Sylvia was in complete shock at what had just happened. It wasn't like Lexi to do that, so she wondered what was going on. Chalking it up to being tired she decided to let it go and not linger on the thought. Just as she went to turn around to sleep she noticed her brother supporting a full erection under his shorts.

"Oh my god! There's no way that just happened. There's just no way!" Sylvia was screaming in her head, over an over again. She couldn't comprehend what had happened. "Was that because of Lexi? I can't believe it!" She shook her head at the thought. "It looked so big. Ahh shut up, shut up!"

Lexi put the big shirt on and lay down onto her bed as she noticed her sister shaking her head from side to side. As she laid there waiting for sleep to take her, she imagined the impact she had had on her brother. "I wonder if he noticed. I can't believe I just did that."

Tobias was fully awake at this point. "I can't believe I just saw that. What the fuck was that about?" Horny and annoyed at the fact that he had an erection from his own sister and couldn't do anything about it, he tried to think of something else, anything else.

After hours of remaining awake lying in bed, the three finally managed to sleep. Each one dreamt something raunchy involving one or two of their siblings and for the next several weeks, their thoughts and desires only grew stronger with every passing day.
