Jessica's expanding ass

    by: LGV Author IconMail Icon
Even as her brother, you have to admit that Jessica's figure was rather lacking. From a young age the girl had enrolled in a vast variety of different athletic programs, ranging from traditionally sports such as basketball and soccer to ones not typically played by women, such as hockey and football. All the hard work had made her as healthy as a horse, though for a girl in high-school, this had some unfortunate side effects. Her body was in a near-constant need for energy, starving her figure of fat. Energy that should have gone to fattening breasts and widening rumps instead was used for kicking balls and tackling foes.In the end, she found her chest to have grown to a paltry A-cup and backside that was as flat as a piece of cardboard.

Being the nice brother that you are, you decide to rectify this. Stuck between growing her boobs or her butt, you decide to go with the latter as she is less self conscious about it. Indeed, if there was one true benefit to all that exercise, it was that her ass and thighs were toned to a mythical degree. She prided herself on the fact, but even you could tell that she was always wishing for a curvier figure.

It's time to grant that wish. You click on the butt size tab, prompting a slider to pop up on the center of the screen. Underneath the bar is a number line, though you've never been familiar with women's' size measurements, so the are utterly meaningless to you. At the moment, the slider sits at an arbitrary "10". Throwing caution to the wind, you drag it a great deal to the right, eventually bringing it to rest at "30". You watch with glee as the image of your sisters backside bounds outwards, growing rapidly with fat. You compare it to a balloon being rapidly expanded. Before long, the growth comes to a halt. Her ass, once unattractive and flat, is now as curvaceous as a Brazilian porn stars.

With the change complete, how do you proceed?

You have the following choices:

1. Call Jessica in to examine her in person

2. Change Jessica even more

*Noteb*
3. Try experimenting on yourself

*Noteb* indicates the next chapter needs to be written.
