She went on pleasing him like that for a minute before she licked her lips. “I want to… taste you Jake.” She whispered to him.
Jake tried to speak but the pleasure was to great, he simply nodded and smiled at her.
Her eyes twinkled as soon as he gave her his okay. Casey opened her mouth and slid her brother’s cockhead inside, she then closed her mouth and started sucking on it while her tongue ran up and down his slit, she could taste her brother’s thick precum and felt her pussy react to it.
“Ooooh shit Casey!” Moaned Jake as he was being attacked by his horny sister.
Casey slowly started to bob up and down, her mouth taking his cock deeper inside with every up and down motion. With her right hand she softly cupped his balls and made rolling motions with her fingers.
Jake couldn’t believe what he was witnessing, his usually shy sister down on her knees, sucking his cock with as much effort as possible. He looked down at her and noticed her big eyes staring back deeply into his. He could see pure love and arousal in them. He had missed her too, all those years without her presence made him realize how much he loved her. He knew it was wrong what they were doing but he couldn’t resist her any longer. He stroked her wet hair softly and placed a loose streak behind her ear that was covering her face.
They were both hypnotized by their eyes as Casey continued to bob up and down her brother’s cock, all the while keeping contact with him without ever looking away. She felt his precum coat the inside of her mouth as she sucked and slurped on his hard cock, a little bit of drool escaped her wet mouth every time she reached his cockhead.
Their sounds of erotic coupling were suppressed by the falling water, but Jake moaned heavily now and so did his sister, he could feel his cock vibrating every time she moaned. Far in the back of his head he wondered how long they were going at it, it has to been at least fifteen minutes.
With a loud plop Casey released herself from Jake’s throbbing cock, now coated in his precum and her saliva. She coughed a few times before speaking. “So tasty Jake… I want to make you cum… Do you want your big sister to make you cum?” She moaned to him while slowly stroking his cock up and down with her hand.
“y-yes… Make me cum Casey, please make me cum.”
She giggled again. “So cute… You know that I can’t resist you little brother.” She then placed both of her hands onto his knees and gripped them tight. “I’m going to make you cum now… Big sis is going to take you to heaven.”
She opened her mouth wide and threw herself onto her brother’s cock in one go, she managed to swallow about two/third of it before she started to gag, she would need a little more practice to take him in full length.
“Fuck!” Yelled Jake loud while he watched his sister deep throat him as best as she could. Her soft lips ran up and down his cock with incredible speed, her warm mouth coating his cock with her saliva and his precum that now leaked in full force.
Casey slid her tongue around his shaft every time she took him deep. Her pussy was now on fire and she felt her juice leaking out of her with each bobbing motion. She made sure that every time his cock entered her mouth she would suck as hard as possible giving him full pleasure.
