The Island of Three Ch. 04

Lexi crawled between them, giving her the perfect view of his crotch. She looked up at her now sitting, big brother and licked her lips in anticipation. Tobias was already hard at the thought, and grabbing her tit had only increased his girth.

His sister's hands started to remove his boxers. They got stuck on his erection and lifted the elastic over his aching cock. It sprang back up to attention as soon as she had removed them. Lexi's mind went blank. She needed it inside her mouth, and didn't hold back for a second as she grabbed hold of it and began to stroke the shaft up and down.

Tobias noticed his cock looked massive in her small hands, so big that he wondered how she managed to fit it in her mouth just hours earlier. He looked over to Sylvia, half expecting her to suddenly jump up at what was happening, but she was sound asleep and heavily breathing in and out.

Lexi was on his hard member instantly, sucking half her brother's cock into her wet mouth. Tobias threw his head back at the sensation as she went to work. Lexi was pumping his cock in and out of her mouth, faster and faster with every passing second.

Tobias noticed something different this time around: Lexi was moving faster than before. She was delving deep down his shaft, and then bringing it out before delving back down. She was trying to make him cum. Earlier on the hill, she was enjoying herself, taking her time and savouring it, but now she was ravaging his dick.

"Oh shit Lex," Tobias whispered as he grabbed the back of her head and guided her down onto his cock.

"Mmm hmm," was all she replied.

The darkness did a lot to hide their actions, but Tobias could see his hot sister trying to cope on his rod. Even with her enthusiasm, she couldn't swallow his entire length. It would hit the back of her throat and then come back out. He noticed she wouldn't gag on it, but she couldn't force it down either. He realised it'd take practice, and the thought caused his cock to thicken and stretch her mouth even more.

Lexi pulled it from her mouth. "How does it feel bro?" her eyes wide, staring up at him.

Tobias was in heaven. An expert cock sucker, a prefect babe and his sister was giving him a blow job, while his other sister was sleeping not 5 metres away.

"So fucking good," was all he got out before pulling her head back to suck his cock. She willingly let him back in and started bobbing back up and down.

Lexi's hand began to jerk his erection into her mouth, with every down stroke she would swallow his cock deep into her mouth and back out, followed by her hand. Her golden brown hair waved around her angelic face at the movements. She was so beautiful.

Tobias wasn't going to last much longer as the urge to blow his load heightened.

"Fuck Lex, I'm going to cum!" He said a little too loudly.

Lexi rapidly started stroking faster as she awaited her reward.

"Fuck!" He tried to stifle his voice as much as possible as wave after wave of hot cum shot out to the back of his sister's throat. Luckily there wasn't as much as earlier and she was able to swallow it all without any problems.

Lexi continued stroking and swallowed every drop of the precious fluid until his member began to subside.

"Jesus!" His breathing, along with his heartbeat was rapid.

Tobias still found their actions crazy. What had he done to his little sister? She had always been so sweet and innocent. "Wait a second. No she hasn't! She's always been mischievous and up to no good. I'm surprised she hadn't jumped on my cock before now," he thought.

"Are you ok Lex?"

Lexi still kneeled before her brother, licking her lips clean. "Amazing! I'll never get tired of that," she whispered. "I better get back to bed before Syl wakes up."

Lexi rose to stand in front of her brother. Just before she walked off to her bed, he grabbed her arm.

"Oh I don't think so," Tobias grinned at the busty babe. "It's my turn."
