Sylvia Accel wasn't always an only child. In fact, she had a mother and sister for a few years after she was born, but all three of them were slaves to her father, Brayden_Accel. Still, it was a life she was happy with. She serviced her father and did as she was told like a good slave, as did her mother and sister, and they all lived together and could be happy. That is...until her mother said no.
Brayden wanted to knock up Sylvia's sister, as punishment for always sneaking out, and told her mother to hold her down so he could. But, the mother said she wouldn't do it, and so as punishment, he instead cock-vored Sylvia's sister, before swallowing her mother, right in front of her eyes! Sylvia was left as an only child after that...
She now follows her daddy's commands without question, no matter what they might be. She'll service his cock, go down on all fours and act like a dog, she'll even let him breed her if he wants it. Anything....for Daddy...
