Emma's head was off the bed, her hair in a tight, gleaming ponytail trailing down to the floor, sucking on her brother's hard cock as he aggressively fucked her mouth. Her ample, supple breasts jiggled with each thrust and heaved with each raspy breath she took. Her legs were spread wide, with each ankle cuffed to the corresponding wrist. All her holes were easily accessible to her brother, and she would not have had it any other way.
James loved dominating his beautiful, younger sister as much as she loved subjugating herself to his whims. Neither of them much enjoyed flogging or anything of the kind, but the mixture of pain and pleasure from contorting her lithe young form and testing the limits of her flexibility, yes, God, yes.
As he thrust into her tender mouth, he extended his arm forward, pressing the vibrator against her soaking-wet, willing pussy. Her eyes opened like moons, and he could see her abdomen ripple as the orgasm hit. He loved nothing more than taking control of his precious, tiny Princess and pleasing her, endlessly testing the limits of her endurance.
Removing the vibrator from her inflamed slit, he placed it on the bed and firmly took her head in both hands. He thrust harder, whispering that he would soon cum, and to be ready to swallow every drop. Midway through the fifth thrust after his warning, he erupted warm, salty semen spewing into her warm, willing mouth. She sucked on his member energetically, desperate to secure every drop to please him.
He gently maneuvered her head back onto the bed, arranging her head so that it rested on soft, fluffy pillows.
He lovingly stroked her cheek, and brushed some stray hair away from her eyes, and sighed with contentment. "Well, Emma," he whispered, "this is the last time in this house. We're starting our new life together tomorrow."
She smiled at him. This was the only home they had ever known, but they would need to relocate somewhere no one knew them if they were to continue their relationship. They'd mutually agreed it would be best for her to attend college as planned a thousand miles away. He would join her and continue to take care of her but had arranged for a new fake identity to conceal their secrets. They were both excited to embark on this new adventure.
