Ever since Jeff's dad left his mom after he was born, she'd never really been able to connect with Jeff, being a busy single mother. He never got to do typical 'father and son' things like playing sports together and fishing, but Jeff thought that this program could be the perfect chance to fix that.
He selected his mom on the list of subjects, and started scrolling through the options to find what he wanted. Intrigued by all of the parameters on the screen, he first chose the box labelled 'Sex' and changed 'Female' to 'Male'. The 3D model of his mom quickly reshaped itself in the corner, becoming essentially the same person but with narrower hips, wider shoulders, and a more masculine facial structure. Next, he changed the individual boxes, changing her height to 6'1, weight to 210 pounds, and body type to 'Muscular'. The model then changed to be much more attractive, looking almost like a model, except for the pudgy face. Jeff tweaked the facial features for a few minutes until he had a face which he was happy with, looking both well-groomed and rugged at the same time, and clearly not the same person as before. After that, Jeff changed her age from '40' to '36', which only really made her muscles more toned. Last of all in the physical category, he of course made sure to increase her endowment.
Next, Jeff had a look over the 'Lifestyle' options. Under 'Career', he changed it from 'Accountant' to 'Amateur Rugby Club Coach', and changed her hobbies from 'Reading and Cooking' to 'Rugby and Sex'. He noticed that her body changed slightly from this as well, becoming slightly thicker and rugged, and genitals growing.
Excited to see what his new mom, or rather dad looks like, Jeff presses the 'Confirm' button, and runs downstairs to watch her changes.
