Katherine jumped in the middle of the two and said "stop" her two friends did stop, but they had accidentally fired two shots which hit Katherine. The girl groaned a bit as her vagina grew into a dick and her right breast expanded into a C-cup. Katherine then said "How about we stop this little fight and actually experiment?" She took a look at her chest and Sandra's chest and asked "Hey Jake mind shooting my in the chest again?"
Jake a little skeptical shot Katherine in the chest, and the C-cup boob retreated inward leaving Katherine flat chested again. Katherine smiled and said "I knew something like that would happen. The gun is like a switch for a type of growth. Why not call it the switch?"
Jake sighed and said "Why not?"
Katherine then said "And I believe Sandra's gun changes genders... Since now my crotch is different... Now let me test my gun..." Katherine shot Jake in the crotch again.
Jake yelled out "Stop shooting me in t-" and then put his hands to his crotch as a dick grew back in and then said "It's back and... different?"
Katherine shot him in the crotch again and his vagina went back and Katherine said "Welp I think my gun switches a body part with another person... which just leaves Timmy. Shoot me quickly... and Jack why not help Sandra out and even her out a little."
Jake shot Sandra around the chest area making her right breast grow into a D-cup as well smirking as he wanted her to keep a change since he was with his female vagina now. When Timmy shot Katherine on her face Katherine flinched as her face too mature a bit till her face looked like it belonged on a teenager.
Timmy said "Katherine you look older."
Katherine said "Shoot me again, maybe i'll go back to normal." Timmy shot again, but Sandra's face matured even further till her face was that of a young woman's.
Timmy responded "No good... you look even older."
Katherine guessed "Ok so Jakes is a switch for growth, Sandra's changes someone's gender, mine switches body parts, and Timmy's makes someone older... what should we do now?"
