Wendy

You pull up your step-mom's profile on the program. You see a naked 3D image of her slowly turning around. You start by manipulating her body fat, putting more fat cells in her ass. Then you see a bar that says "appetite" and increase it, and decrease another bar that reads "metabolism." You then increase her desire for fattening foods. You think how nice it'll b to see her gain weight in her ass. "Serves her right for always being such a pain in the ass," you say quietly to yourself.

You then see the section on sex drive. You have a devilish idea. You crank up her sex drive, but then you remove her ability to orgasm. You chuckle to yourself as you think of how frustrating it will be for that bitch: horny all of the time but not being able to get relief. She would be climbing the walls soon.

You play with the program and find you can make Wendy become extra horny after 9 PM. You can imagine her now, lying in bed with her vibrator going full tilt but to no avail, fucking herself until the batteries run out or her pussy is too sore.

You then manipulate her mind, so that she will believe anything you say.
