The Island of Three Ch. 03

Tobias wanted nothing more than to plunge her down onto his rod as fast and hard as he could, but knew that he would have to take it more slowly. Even though he was pretty sure that she wasn't a virgin, it had been at least a few months since either had a real sexual encounter. Tobias was bigger than average, so going in full force might be uncomfortable at first. He wanted them both to fully enjoy what was about to transpire.

Their lips locked in a frenzy of passion as Tobias grabbed hold of his sister's firm ass cheeks. He squeezed harder than he meant to and was rewarded with a powerful moan from his little sister. His cock was pressing deep into her opening, begging to be inside her wanting pussy. Lexi was pushing down trying to be penetrated by her brother's impressive cock, but he held her tight, not letting her take control.

Tobias could tell she was ready, and more than willing to accept him fully. He began to kneel down, all the while holding her close to his skin. Her nipples had become solid nubs of joy that poked into his chest almost painfully as he lowered her.

Lexi broke the kiss to lie on her back against the soft grass. Tobias was now leaning over his sister, his hands on each side of her beautiful face and his eyes looming down over his target. Lexi blushed as her brother's eyes roamed over every inch of her skin. Her legs were still wrapped around his waist, holding his meaty cock in place, waiting to be penetrated.

"Are you sure about this Lex?"

Lexi stared deep into her brother's eyes with such force that Tobias knew her answer before she said a word. "Fuck me Tobi," Lexi spoke in a sexy voice.

Tobias couldn't help feeling like he was about to do the one thing he knew he shouldn't. On one hand he was about to have sex with his twenty year old younger sister, one of the people he set out to always protect. And on the other, he had this sexy vixen that was practically begging to be fucked. His thoughts were conflicted, but he knew what he wanted and what she wanted, so he gave in his the inner voice.

Tobias aimed his cock at her entrance and took one last look at his sister's erotic face as he thrust forward. She was so wet the head of his cock slipped in easily. Lexi moaned aloud as the first of many inches began to enter her wanting pussy.

Her legs were pulling on his hips to drive his straining dick further inside her. He held back in fear of hurting her, but continued his descent into heaven. He pulled almost all the way out before driving back inside until about half of his cock was inside her. She was as tight as he expected, and he knew that it would've been painful to go in full force, even though it's what they both wanted.

"You're so tight Lex," he spoke in a breathy voice. "Are you ok?"

"Oh my god you're big!" Her facial expression showed that she was in pure bliss. "Don't stop Tobi. I'm ok."

Tobias lowered his head to kiss his sister, all the while pushing further and further inside her. The kiss was met with passion and a primal need of total forbidden lust. His cock was almost all the way inside her now, only a couple inches left. He broke the kiss and started tracing his lips down her neck towards her breasts.

"Oh that feels so good brother."

He realised that she called him "brother" instead of his name. He wondered if Lexi was enjoying it more because it was him that was fucking her or if it was just someone giving her sexual relief. All he knew was he was finding it hotter than usual. Fucking his sister was much more intense than his previous partners, a taboo so strong it brought on a forbidden lust for siblings.

His lips reached her mound and he started to lick down toward her protruded nipple. He was desperate to get it inside his mouth. He wanted to bite and suck her breasts raw until she couldn't take anymore. His tongue danced around her perfect nipple, not allowing it inside his mouth just yet. Tobias could feel her sex getting wetter at his actions and started to pulse with every thrust of his hips.

"Tobi stop teasing me. I need you fully!"

Tobias latched onto her pink nipple and sucked hard while thrusting his hips down, pushing his cock fully inside his tight younger sister's snatch. Delving as deep as he could go, he moaned around her breast as his tongue lapped at her hard nipple.

"Fuck! Oh fuck Tobi don't stop!"

Lexi moaned and shouted so loudly he wondered if Sylvia all the way back at camp might hear them.

He gave her breast one last squeeze and suck then raised his head to look at the reaction he was causing. Tobias was rewarded with an expression of pure pleasure. She was in heaven, and if he wasn't mistaken, she was close to another orgasm.

His cock was now retreating almost all of the way out, then back in to the hilt in rapid succession. Lexi's moans became louder and more frequent at every thrust. Tobias couldn't help his own orgasm from rising but tried to hold it off as long as possible, hoping to enjoy the feeling for longer. Her tits were bouncing up and down, causing Tobias's cock to grow harder than he thought possible.

"Oh god Tobi I'm going to cum!" Lexi's eyes closed hard as Tobias could feel her sex clamping down on his cock. Her body spasmed in waves as her orgasm took hold.

"Fuck! Fuck Tobi don't stop fucking me!"

He listened to his little sister's dirty talk and fucked her harder and faster than before.

Tobias looked down at his busty sister. Her breasts bounced, her eyes locked shut and her body jumped as her intense orgasm finally began to subside.

"You're so hot Lex!"

He stared at his sister, speaking the truth. She was a babe, and he was finally seeing her as the hot piece of ass that she was. Tobias shoved his entire cock inside as the last spasm of her bliss ended. He then realised that he was stuck on this island, and could now fuck her brains out whenever he wanted!

"Oh my god Tobi." Lexi was out of breath. "That was insane! I don't think I've ever cum so hard in my entire life!"

His ego boosted in that moment. He gave his sister the best orgasm she had ever experienced and it was given to her from sheer forbidden sex. Getting so lost in the beauty of the woman under him, he almost forgot he was fucking her. Lexi was his sister, but she was so much more than that now.

"This is so wrong, but feels so fucking good!" Tobias then started thrusting again, faster and faster he pounded into her tight pussy.

"Fuck me Tobi! I want you to cum inside me!"

Tobias knew he shouldn't; it was too dangerous without any protection. But in that moment of pure passion, his primal instincts took over and controlled his body for him.

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

"That's it. Cum inside your baby sister."

Her words spurred him on as he felt his orgasm rise through him. Tobias slammed his cock as deep as it would go and then climaxed. His body stiffened as each burst of hot cum shot itself deep inside her. Lexi felt it filling her up and moaned at the pleasure. It felt like a never ending orgasm as his balls drained themselves.

Finally his orgasm faded, leaving his cock buried in his sister. He raised himself up to gaze upon her gorgeous face once more. "Hey Lex."

"Holy fuck." Lexi pulled her brother down for a long kiss before letting him go and continuing. "That was amazing! I can't believe that just happened!"

Tobias tried to pull himself out of his sister, but she still had her legs wrapped around his hips.

"Oh you're not going anywhere!" she grinned.

Tobias didn't regret what they had just done, but he couldn't help feeling like he had taken advantage of her. "How safe was it to do that Lexi?"

Her grin widened. "You mean cum inside your little sister?" She smiled an innocent smile.

Hearing her say the words caused his dick to jolt which then caused Lexi to moan slightly.

"Yes. To do that."

"Say it for me bro," she pouted.

Tobias sighed and gave in. "Was it safe to cum inside you Lex?"

Lexi laughed. "Safer than it would have been a few days ago. Don't worry, I keep pretty good track of this sort of thing. We'll be fine."

"Thank fuck for that." Genuinely relieved he began to realise what he had just done and looked away from his sister.

"Hey. It's ok Tobi. I wanted this. Don't you get all apologetic on me."

"You know we shouldn't have done that. It wasn't right."

"Tobi. That was literally the best orgasm I have ever had, and we're doing that again. I don't care what anyone says. It can't be wrong if it feels that good."

She had a point. Tobias looked at Lexi and noticed that she was easily the most attractive woman he had ever been with. Whether or not they were related, it felt fantastic for them both, and Tobias wanted more.

Lexi's legs finally came undone, releasing his hips from their grasp and allowing his now flaccid cock to slip free. He raised himself up, putting all of his weight down on his knees as he looked over his curvaceous sister.

"My god you're beautiful."

Lexi blushed and found herself a little flustered as he loomed over her naked form. "You're only now noticing?"

"Oh I noticed a long time ago."

Lexi grabbed hold of her perfect breasts and looked Tobias directly in the eyes as she played and twisted her nipples. "Whats your favourite part?"

He had to think for a moment. Before now Tobias tried not to think of his sisters' bodies sexually. He thought long and hard. To him her breasts were perfect; fantastic size and shape with easily the most erotic nipples he had ever seen. He hadn't got a good look at her ass just yet, but if the bikinis she wore were anything to go by then her ass was just as perfect. He knew his answer.

"I think all of you is perfect Lex, but if I had to pick just one thing..." Tobias grabbed her hands, pulling Lexi up as he dropped down onto his back, bringing her with him so that she was now on top of him. Lexi sat on top of him with her legs either side. Her perky boobs poked out and caught his eyes immediately. "I'd have to say your lips."

The movement caught her off guard and she squealed at the surprise. She settled on his lap and couldn't help but play with her breasts once again. "My lips?" She raised an eyebrow. "Do you mean my other lips?" Lexi looked down towards her sex.

Tobias laughed as he enjoyed the show he was given. "That too, but I meant your mouth. Speaking not as your brother I would say I find your voice an extreme turn on."

It was Lexi's turn to laugh. "What? Why?"

"I don't know how to explain it without sounding like a creep."

She eyed her brother's strong body before looking back at his face. "Then try."

"Well, when you know what you want you talk with a cute but stern voice. It's nice to listen to. I never get bored hearing your voice and sometimes I would imagine how your voice would sound during sex. Now I don't have to," he smirked.

"That's the hottest and sweetest thing anyone's ever said to me." Lexi leant down and embraced him in a kiss.

They rolled around in the grass, kissing and caressing each others bodies for an endless amount of time. Tobias had now fully invested in his love for Lexi, and Lexi did the same for her brother. They didn't have all of the answers to what would happen next, but they weren't going to allow any problems to arise.

"We should probably get going. Sylvia will be getting worried."

"Yeah we still have a small climb ahead of us," Tobias spoke as he looked up the hill ahead of them.

"Wait, you still want to reach the top? Why?"

"Lex, we might be here for months, maybe even years. We should know all of the island."

"Ugh fine. Let's go."

Tobias walked over to his clothes and proceeded to get dressed. Lexi was reluctant to dress, but decided they had all the time in the world to fool around naked. Tobias slapped his sister's peachy ass as she began to put her shorts on, causing Lexi to yelp in pleasurable pain.

Minutes later, they were nearly to the top, talking about what they could do to be alone from time to time. Their steps got heavier as exhaustion set in, but they continued onward, persevering to see the island completely.

"We could say that we need..." Tobias stopped mid sentence as he reached the top, and looked down at something amazing.
