The old man had said anything, right. Any thing at all about the feature on another person. Your mind ran away with the endless possibilities, but you decide to start small. You have always been a boob man, and probably always will. So the ability to control the boobs on a woman would be incredible. You start looking for a bottle labeled Breast. Bu tot no avail. The surprising number of bottles on the shelves is far too good at hiding what you want to find, but you are determined that it is in there somewhere.
After about an hour of searching, you lean back against the shelf behind you frustrated beyond belief. You look over the shelf hoping to high heaven that it was just hiding in plain sight. You don't find it, but on the far side of the shelf you see a mysterious looking box that reads, "Find what you are looking for?" Standing up you approach the box and examine it, only to find it is a conveniently placed search index on the contents on the shelf. You proceed to face-palm about twenty times before searching for your item. You don't find a bottle labeled Breast, but a reasonable replacement is the bottle labeled Chest, which you assume to have a similar effect.
Locating the bottle you quickly scan the instructions on the side before downing the teaspoon of liquid inside. Your whole body tingles before you look at the price tag. Surprisingly its only $10, easily covered by the hundred in your wallet. Pulling out the leather square from the pocket you look inside to find that your hundred has been replaced with $90 and a reciept. Satisfied you proceed to leave, but not before a couple walks in, hand in hand, to browse the aisles. You examine the girl and find her lacking in the boob department, which you ccan now fix with your new power.
