This is a convoluted story of Steve, his two sisters, their girlfriend, and Mary. By the end of the story he has fucked all four women, and is set to marry Mary.
Now the problem. Is Mary the mother of the third teenager, or is she her sister?
James B fails to confirm their relationship as he jumps from daughter to sister in the same paragraph, seeing as how the young girl is sucking steve's cum out of Mary's cunt I can only wish it is her mother.
