You decide to try it out. You select number 5 and point it at yourself, and click the green trigger. Almost instantly, you dick grows to 10 inches hard. You then think up a quick plan of action and head back over to your sister's room with the gun. Selecting number 1, you open her room door.
"Hey sis, I figured out how to fix your boobs a little."
"Okay well don't fix them too much, I still want them bigger than what they were."
You point the gun at her and pull the red trigger four times, until her boobs start gradually shrinking to FF cups. You then toggle the settings on the gun to number 2 and shoot her twice with the green trigger, and her butt begins to expand. She lets out a soft moan of pleasure asks what you're doing, but you ignore her. You then switch it again to number 6 and shoot her another 5 times with the green trigger. You begin to notice a large wet spot developing on her strained panties and she looks at you, biting her lip.
