This is a new, updated and expanded version of the classic female muscle growth story by Lingster.

A strange computer application is provided to two college women, which lets them alter those around them as if they're characters in a video game: "buffing" or "nerfing" them. To buff someone means to make them stronger and more formidable, to nerf them, the opposite.

Vanity, revenge, desire, a sense of justice, and sheer entertainment value provoke the two into altering themselves and the people they know, but what effect will the transformations have on their relationships and their ultimate fate?

This story features a lot of female muscle growth, some breast expansion, and a bit of male shrinking and growth. It also features social and sexual interactions between incredibly strong, muscular women and much weaker men. One the major plot lines focuses on a woman named Claire and her boyfriend Paul, and how their relationship changes as Claire grows taller, stronger, and more muscular even as Paul finds himself losing his size and strength. Another couple experiences mutual growth and various other women find themselves becoming tall and muscular.
