Feeling the hot seed of the man fucking her fill her womb to overflowing, Jack, now Jackie, screams as her new tits balloon out more, her bubble butt jiggles as she is used as a fuck toy.  Lamont laughs at the new girl, a breeder he purchased from the slave market in New York of all places.  Her new form had not yet set, they said, and that she would still experience changes as she is exposed to semen over the next day or so. 

Sure enough, every spurt of his jizz feminized her more and more... And Master Lamont loved making the sissy boy more of his slave...
