"Oh, this little number?" the witchy clerk at the check-out desk asked when you brought the product to the counter. You weren't usually one to believe in magic, but one day as you walked into the local mall and discovered a store that wasn't there before, you were beginning to doubt your disbelief. You expected this "magic" shop to mostly stock playing cards and trick top-hats, maybe even some flash powder. What you didn't expect was to find a strange cardboard box with the words "Universal Remote Control Dart Gun" printed on it in black ink. Such a strange jumble of words would make one believe that it might have been some kind of cheap tchotchke made in a Chinese novelty factory.
"I can assure you that this device is no mere child's toy," the clerk explained as she opened the box for you, "In fact, you should keep this thing out of reach of children. This is, after all, a mind and body control device."
"You're kidding," you scoffed at her.
"Oh I never kid," the witch assured you, "This truly is a dangerous device. Let me give you a simple rundown on how it functions.
"So we have the gun itself. You load this metal dart into the chamber with the pointy end of it facing away from you. Once you're locked and loaded, simply aim the dart at the back of your target's neck and pull the trigger. Don't worry if your aim is terrible, though, because it has failsafe enchantments in place to ensure you always land a hit. Once you've stuck your target with the dart, the fun begins. See, the target can't remove the dart from themselves. Someone else has to pull it out and it has a strong grip. This is to ensure that it doesn't fall out while you have your fun with them.
"The gun has an in-built touchscreen interface that operates like a regular smartphone. This is where you'll type in or dictate your commands to the target. For instance, you could force your target to walk around on all fours, make them behave like an obedient servant, or even make them instantly orgasm. You can even make various modifications to their physical body, like bigger boobs, extra limbs, and even animal features if you're into it. Once the dart is taken out, any mental changes are reversed, but their physical changes are permanent. How you use this gun is all up to you. So would you like to buy? Only $99.99."
You slap a Benjamin onto the counter and soon you're walking out of the shop with a dangerous weapon in your hand. A dangerous weapon that looks like a science fiction prop, but a dangerous weapon nonetheless. You're just itching to give this thing a try, so...
