Alice kneeled in her computer chair, in order to reach the keyboard. She found a menu labeled "Advanced Options" and saw all manner of changes were now possible. On a whim, she selected her chest. It displayed "B" for her bra size. On a whim, she replaced it with FF, and hit execute.
Her breasts began to swell like a pair of melons, until she found herself with a mammoth pair of breasts. Unfortunately, their size mad them sag noticeably, despite the fact she was only a teenager.
Searching through various options, she found a menu for skin. If she made her skin less elastic, then maybe her breasts wouldn't sag!
Unfortunately she wasn't sure how to pull that off...until she saw a bar for "age" and got an idea.
