I just wanted to say thank you. To everyone reading my stories and to those that follow me waiting for them. It means a lot that there are people out there enjoying what it is I have to offer. With that said, I'll let you dig in, and let the fun begin.

Sylvia grasped one of her heavy breasts through the fabric of her bra. All the while her other hand had lowered itself between her silk panties and her equally silky skin. A fast paced circling action was being performed under the material with hypnotic accuracy as she expertly fingered herself.

"Uhh, can... c-can I watch?"

A solid five seconds of silence passed before Tobias and Lexi were able to speak. However, it was left completely up to Lexi, as all Tobias could do was mutter incoherent nonsense.

"Fuck yeah you can!" Lexi shouted with urgency.

Sylvia continued to play with her clit, edging herself closer to climax. The second she heard Lexi's approval, she rested her back against the cabin wall and gazed down at her siblings as they delved back into the forbidden fruit..

Smirking, Tobias immediately delved back down into his youngest sisters snatch and lapped up the juice that had gathered, using it as extra lubricant to circle the most sensitive parts of her cunt. By now he knew exactly what triggered specific responses from her. Luckily for Tobias, he was also naturally gifted at eating a woman out, that was the sole reason he teased her as much as he did.

"Oh god Tobiiii!" Lexi was in heaven. Being watched by her older sister as her even older brother ate her out, made it an entirely different kind of pleasure.

Sylvia picked up the pace, circling her clit with two fingers and sliding them down to plunge into her tight little hole. She repeated this process until her knees began to shake. "Holy shit this is hot!" Her voice barely above a whisper. So quiet not even her siblings had heard what she said.

Lexi reached down and grabbed the back of her brothers head, forcing him further into her slick pussy. The moment she did so, Tobias sucked her little nub into his mouth, causing Lexi's back to arch as she screamed a silent moan to the skies.

Tobias was also spurred on by Sylvia's sudden arrival. The entire time he was giving Lexi head, he was thinking of what could come next. What could potentially be waiting for him when he raised his face. The thought of Sylvia standing there watching them, possibly naked and overflowing with sexual intentions was almost too much for him to take.

Tobias was in a world of his own as he thought to himself. Lost in the image of being stranded on an island with nothing better to do than to fuck Lexi and Sylvia senseless on a daily basis.

"How does it feel, Lex? Oh goddd! Does it feel good to be eaten out by your brother?" Sylvia's voice was full of excitement and genuine curiosity. A tone that her siblings didn't get to hear all that often.

"Fuckkk yes it does! It feels so fucking good Syl. I think..... oh fuck, oh fuckkk, I'm going to cum! I'm going to cum! Oh FUCKKK!! IM CUMMING TOBI!! IM CUMMINGGG!!"

Lexi locked her legs around her brother as her orgasm took hold. The familiar sensation of pure pleasure rushed through every part of her body, gripping her in uncontrollable waves of ecstasy.

Tobias had locked his own arms around Lexi's thighs, keeping him tight against her pussy as she spasmed violently. From his experience, this was the biggest orgasm he had ever caused, and not just with Lexi. He guessed that with Sylvia standing there watching them, the taboo of it all was creating new heights of pleasure.

Lexi was still in a world of her own when the orgasm faded, but thankfully Tobias was able to free himself just in time to witness Sylvia's legs buckle, causing her to fall down to the cabin floor as her own orgasm struck.

"I'M GOING TO CUM TOO!! FUCKKK!! IM COMING!!"

Tobias couldn't believe his eyes. He was watching Sylvia as she reached climax. And the best part about it was that her body reacted almost identically to Lexi's. This brought a broad smile to his lips.

"Oh my god!! I'm cumming Tobi!! Fuckkk! Brother, please, watch me as I cummm!"

Tobias was immediately enthralled by the fact that she wanted him to see her in such a lewd position. Her entire body was jolting abruptly, causing her tits to bounce almost completely out of her bra.

Sylvia's hand was gyrating in her panties with such ferocity that Tobias wondered if it could be hurting her. But from the sound of it, he was very wrong. He took a moment to relish in the fact that to his left was Lexi, slowly coming down from an intense orgasm, and to his right, Sylvia, who was still experiencing her own ecstasy.

"Ok, I have to admit, that's probably the hottest thing I've ever seen. And I've seen some stuff..." Lexi was gawking at her sister just as much as Tobias was. "She hasn't even taken all of her clothes off yet, and she still looks so.... luxurious,"

"Lex, are you lusting after Sylvia? I knew you liked the idea, but I didn't think you would be, well, this into it."

"Huh! You're one to talk mister!" Lexi slapped her brother on the leg, closer to his cock than he would have liked.

Sylvia was coming down from her pleasure filled high only to find both of her siblings staring her down like some kind of snack.

From the vantage point they had on the bed, each of them could clearly see down Sylvia's bra. Now a deep and dark crevice that they both wanted to explore. Even though Lexi had a similar size pair of tits to her sister, they all knew that Sylvia's were in fact bigger.

Tobias stared at her like a prize he had just won. Even though she had just brought herself to orgasm in front of her siblings, she wasn't about to whole heartedly give in to temptation. There was still the smallest amount of resistance left within her soul.

As for Lexi, she gazed down at sister as she played with her own tits, imagining what it would be like to play with Sylvia's. That was when she saw the reality of the situation hit her sister and knew she had to strike fast.

"Umm. I-I'm going to go outside for a bit," Sylvia quickly stood up on shaky legs and walked towards the entrance of the cabin.

Lexi frantically jumped off of the bed and grabbed hold of Sylvia's arm. "Oh I don't think so. You aren't leaving this party until we've had some fun,"

Sylvia turned around to see her sister wearing a broad grin on her face while pointing towards the bed and their brother.

"Lex, come on. Let me go. This was a mistake."

Lexi glided behind her sisters back and reached around to grab her tits, massaging them for their brothers sake. Tobias stood off of the bed and removed the rest of his clothing. His aching cock stood tall, like a proud lion about to catch his first gazelle.

Sylvia softly moaned under her breath as Lexi played with her chest. When she opened her eyes, Tobias' cock stared her down. From this point on, her resolve started to rapidly diminish, her heart rate picked up and her mind went blank.

'Snap'

Sylvia's bra suddenly came loose, allowing Lexi to freely pull it off in one quick motion.

"Your bra just broke! If that isn't a sign, I don't know what is," Lexi spoke into her sisters ear, vibrating her earlobe in the process.

Even though her bra was now being removed, her focus never left her brothers meaty shaft. It was as if she didn't even know it had happened. Slowly she made her way to the bed. Lexi stuck to her back like glue as she softly pinched her nipples.

Tobias grabbed his erect cock and started to stroke it. Aiming his prick at his siblings as they enjoyed each other. Even though he had seen Sylvia without a top on a couple of times now, it was only in passing or a quick flash caused by Lexi. Now seeing her almost completely naked, he realised just how deep her beauty went.

All three siblings were what they would call, their perfect partners. Sylvia liked the strong and dark type in men, and in women she liked the outgoing adventurous type. Lexi liked her men energetic, ambitious and tough. As for women, she hadn't quite explored that area enough yet, but she was finding Sylvia more and more tempting by the day.

For Tobias, he never was able to go for any other type of girl. He loved the curvy and fun type. The kind of girl you wanted to showcase to the world, as well destroy them in bed like the sex machine vixens they were. All three were built for each other, and now was the time to find that all out.

"I've always been a little bit jealous of your bod Syl, but I guess now I get to enjoy it as though it were my own." Lexi lowered one of her hands to the damp patch on her sisters underwear. "You're, so fucking wet..."

"Ohhh... fuuu..." Sylvia was about ready to let go. Let go of every worry and wall that she had built. "I have one request. J-just one,"

Tobias stood directly in front of her, rubbing his cock in preparation. "Anything."

"W-we can't fuck. I know this, well this... sounds a bit stupid seeing as what's... happening right now, but I'm serious T-tobi. We can't fuck."

Tobias could see the seriousness in her face. Even though he didn't really understand why, he knew to respect her wishes. He now wants nothing more than for the three of them to live as one on this island, the one that's become their home, and with Sylvia's decent into incest, he knew it wouldn't be long until his dream was a reality.

"Fine, but if that's the only request, then we're going to do absolutely everything else," Tobias smirked and moved Lexi's hand from Sylvia's snatch. Only to pull her underwear down to the ground and replace it with his own hand.

"Ohhh fuck!!" Sylvia jolted forward as he did, and soon enough she found herself resting her arms around his neck for support.

The three siblings formed a sandwich, with Sylvia in the middle being caressed by her sister, while also fingered by her brother. The familiar electric feelings made their way through her body as she tensed up. A few seconds later and her resolve was gone. She then relaxed and enjoyed her brother and sisters touch.

Tobias realised that he could probably get a blowjob from Sylvia at this point, but there were two things wrong with that thought. One, he was as erect as the Eiffel Tower and would probably cum in a matter of seconds, and two, Lexi would be left out of the fun for the most part. No, he needed another strategy. One that kept them all busy.

While Tobias thought on it for a split second, Sylvia had grabbed hold of his cock and started to jerk it back and forth. His sisters angelic hand felt amazing on his hard rod. Her hands were small, barely big enough to reach all the way around his shaft.

"How does it feel to finally have my cock in your hand sis?"

Lexi was also in her element, kneading and pinching Sylvia's breasts like it was going out of fashion. Feeling the subtle differences in their bodies made her excited. Her nipples had quickly grown hard, and her pussy had been getting wetter by the second.

"I have to a-admit... oh fuck me... it feels good Tobi. I now know why Lexi has been... ohhhh... this forward with you."

They were all so close, mentally and physically. It felt natural, like it was supposed to happen.

"Big brotherrrr. I can't wait any longer. I need..." Lexi brought her lips next to her sisters ear as she spoke. "...your cock inside me."

Every time she did that, Sylvia's entire body shivered with a lustful explosion. Ever since she had started exploring her own sexuality, Sylvia had been a bit of a sex freak. Wanting more and more, even in some of the most inappropriate places. When it came to sex, her personality completely changes for the better.

Tobias took a few small steps backwards until the back of his legs touched the frame of the bed. Then he laid down, resting his elbows down on the bed to prop himself up, allowing him the opportunity to gaze up at his insanely hot sisters.

Sylvia realised what was about to happen, and it took all of her strength not to jump on the bed, lower herself down onto his cock and ride him until she was completely worn out. However, she had her own ideas on how she wanted to spend the night.

"I think that monster is calling your name Lex," Sylvia pointed towards their brothers proud junk.

"Well, we wouldn't want that to go to waste now would we?" Lexi let go of her sister and jumped up onto the bed. "But, are you sure you don't want a go first? I mean, I know that it'll be a completely mind blowing experience, so why don't you take this turn?"

Sylvia walked around the side of the bed, eyeing up both of her siblings. Her body glided seductively from side to side as she moved, then she mounted the bed beside her brothers head.

"Not this time sis. I'll let you have this one,"

"Fine, your loss." Lexi knelt down either side of her brothers lap, grabbing hold of his cock and aiming it towards her slick opening.

"It is my loss, so you better enjoy it. As for me..." Sylvia did the same thing as Lexi, and quickly kneeled either side of her brothers head.

Tobias was completely silent during the whole thing. He watched as the girls voluntarily straddled both his hips and face. Lexi lowered her small frame down onto her brothers prick, and then began bouncing up and down on top of him like a jack in the box. Sylvia followed suit and slowly started to lower herself down onto his face.

"Fuck yes! It slipped straight in. Fuckkk me yes!" Lexi could feel her brothers thick shaft sliding deep into her pussy. "It's so fucking big Tobi! Your cock feels so big inside me!"

Lexi was in pure heaven, but even Tobias wondered whether she was putting it on just a little more than normal. He thought it might be to tease their sister. He figured it was definitely something she would do.

Tobias gazed up at the perfectly trimmed little snatch that he was about to snack on. She was wet, really wet, to the point that he worried that he might drown if she wanted him to. And the crazy thing about it, he would probably let it go that far if it meant he could eat Sylvia out.

"I-I'm about to do it, Tobi. A-are you sure that...."

Tobias reached his arms up and wrapped them around her thighs, pulling her down and onto his face. The moment her snatch was brought into contact with his mouth, he got to work. The first thing he noticed was that she tasted slightly different to Lexi. Not bad different, just noticeably so.

"Shiiiiit!" Sylvia screamed out a moan at the forceful act of her brother. Along with his tongue working it's magic, he nearly caused her to cum on the spot.

This was the first true sexual act she had done with one of her siblings, the first taboo indecency, and she couldn't be more ecstatic about it. The moment her brothers tongue touched her slit, her fears, her doubts and worries about what she was doing, fell away, like they were nothing compared to the sensation she was feeling.

"Does it..." Lexi suddenly let loose and frantically bounced on her brothers dick. "...feel good Syl?"

One of Sylvia's hands started to play with her breasts, while the other made its way to her mouth to stop her moans from escaping. She felt as though she had to hide her pleasure, not wanting to let her siblings know they were right all along.

"Mmmmmfckkk!"

"I'll take that... as a y-yes then. Fuck! Why haven't we... mmhmm... been doing t-this for years?" Lexi followed her sisters lead and began to play with her own impressive fun bags.

Soon the three of them found a rhythm. One where Tobias thrust his hips up slightly to match Lexi's down stroke. At the same time he stuck his tongue into Sylvia's tight hole. From what he could tell, she was very very tight.

Every time Lexi pounded herself down onto Tobias' cock, he pumped his hips up to match her. This continuous movement caused Lexi to feel unimaginable pleasure. So much so that it wasn't long until her second orgasm started to loom on the horizon.

Sylvia's mind had completely gone blank. This side of her, her sexual side was appearing once again after so many months without it. She knew that if Lexi wasn't the one on her brothers cock, then she she would be. She was somewhat thankful for it, but at the same time she found herself a little sad.

Tobias' tongue was doing untold wonders to her privates, and just as Lexi's second orgasm started to build, so was Sylvia's. If he hadn't been completely enthralled by Sylvia's tight cunt, then he would never have lasted as long as he had. Concentrating on causing his sisters to experience as much pleasure as possible, stopped him from reaching climax himself. But even that wouldn't be enough to save him in the end.

The girls shared a look at each other, one of lust and hunger. Suddenly they both leaned forward, Tobias was unsure why, but he was still able to eat Sylvia out effectively, so he paid it no mind. At the same time Lexi also shifted, just enough for him to notice the slight movement of her hips.

"Wait, they're leaning into each other. They're not...?"

Lexi and Sylvia were embracing in their first sexual kiss. Both of their tongues as smooth as silk. Their saliva mixed together for the first time as they explored the others mouth. Their hands involuntarily started to feel up the babe in front of them. Grabbing and caressing the other. Their necks, breasts, hair and backs in a primitive act to feel and experience the new undiscovered territory.

"Ohhh shit!! Sylvia, this is so fucking hot!" Lexi got a few quiet words out as Tobias powerfully pumped his prick upwards. Immediately after, she went back in to kiss her sister, grabbed a hold of her big tits and twisted her nipples.

"Fuck, Lex! I think I'm going to cum! D-don't stop!"

Tobias could feel the familiar feeling of his Lexi's cunt pulsating on his cock. He knew she was seconds away from her orgasm. Then, the same thing happened with Sylvia's. Her tight little hole started to grip his tongue slightly.

"I'm going to cum too Syl!!" Lexi's back arched up and out towards the cabin ceiling as her climax took hold.

"Fuckkk! OH FUCKKK!!" Sylvia's body mirrored Lexi's as both busty babes exploded with ecstasy. "OH MY GOD! MY BROTHER'S MAKING ME CUMMM!!"

Both sisters screamed into the night as their second orgasm hit them like a bus. Through some miraculous turn of events, they both came a hard and heavy orgasm, ripping through their bodies like a tidal wave at the exact same time.

Somehow Tobias had managed to hold back. He knew that if he was on the outside watching the entire thing, he would have cum several times over by now. However, this worked out in his favour, because he knew exactly how he wanted their night to finish.

"Fuck. Fuck... fuck me, that was... just... Jesus Christ!" Sylvia was only able to bring a few words together. Being the first sexual act in months, outside of masturbation of course, it took a heavy toll, causing her body to jolt with a few smaller shockwaves of pleasure as her brother continued to lick away at her clit.

"Oh my god! I can't believe that just happened. That was sooo fucking hot. We're doing that again!" Lexi had slumped over and rested against her sister for support.

Sylvia couldn't take anymore, and had to get up from her brothers face. She shimmied back on the bed and sat down to take a much needed breather. Lexi soon followed suit and managed to jump off of her brothers still hard cock and stood beside the bed on unsteady legs.

"How! How did that not make you cum too? What are you, some kind of robot?" Lexi spoke in a worn out tone as she stared at her brothers engorged state.

"Uhhh, I'm sorry if this is a little forward you guys, but is it always like this? Are you ever able to make Tobi cum?"

"Hey! Fuck off! Of course I can! Just this morning in fact!"

Sylvia looked at her sister with a skeptical look. "That was a blowjob. That doesn't count."
