Your 17-year-old sister Alice has knelt down in the hall, collecting items that seem to have spilled out of her purse. She’s in a green blouse and a black skirt, apparently just back from a date.
“Oh, let me help,” you say, starting to kneel yourself.
“I can do this myself,” she snaps. She grabs an object and quickly puts it back into the purse, apparently hoping you wouldn’t see. You did get a quick glimpse of a white cylinder, which you first think is a sex toy, but then realize was probably a tampon.
An idle thought, though, crosses your mind: what if Alice did have a sex toy in her purse?
As Alice stands up, her clothing quickly alters. Her skirt loses about half its length, her blouse tightens around her chest and ties itself off just under her breasts to reveal a pierced navel, and she goes up on her tiptoes as her flat shoes turn into high heels. The makeup on her face becomes more prominent, and the rubber band that was holding her hair into a ponytail disappears; both her makeup and hair look a bit disheveled somehow.
“What?” she asks. “Do I have, uh, something on my face?” She raises a hand to wipe the area around her mouth, and you see that her fingernails extend well beyond her fingertips -- you don’t remember her having a manicure, but she has one now.
“No, you’re fine.” You suddenly realize that you shoved the stone in your pocket when you got dressed, and you’ve had your hand in your pocket touching the stone the whole time.
“Great,” says Alice. “Later.” She walks away and disappears into her room, closing the door behind her.
You stand in the hallway, taking a moment to think. Apparently the stone would respond even to idle “what if” thoughts, so you should probably be more careful. It had changed Alice into a version of herself that carried around a sex toy, or at least had put one into her purse for the date she’d been on, which meant --
You clap your hand to your mouth. From the obvious evidence, it seemed that this version of Alice had sex on her date.
There must have been more to it than just making your sister into a slut, though. The reality change must have at least affected your mother, too, to have her let Alice out of the house dressed like that. In fact, you couldn’t believe Alice would have clothes like that in the first place. So maybe, you think, no matter how you change reality, the stone will make it “okay” somehow?
You pull it out of your pocket and look at it in your hand. Aside from its faint green glow, it looks just like a normal Earth rock; even having seen it in action, it’s hard for you to believe it has the powers it possesses.
The possibilities seem nearly endless, but you decide...
