There were a few misadventures ahead as Jennifer attempted to undo the mess the gun had made, like when Jim's head vanished.
Luckily, she restored it quickly enough that no lasting harm was done, but that proved to her that this gun was dangerous!
Soon she got Jim's mouth back on, and he was able to explain to her which settings to use. Jen got her vagina and breasts back, and Jim got his cock back. "Yay, I'm a guy again!"
"You can have it, ew. So why was this thing set to steal breasts anyways, if it was for your girlfriend?"
"Wrong gun. I made this thing last week, but wasn't sure what to do with it. I thought I had the breast expansion ray. I was gonna double her size for her birthday!" Jim grinned.
Jen aimed the gun at him and stole his balls and cock.
"Ack, no, why did you do that?"
"So you can't think with them. How big is she?"
"Oh she's a D-cup."
"Moron! She'd be enormous! That would be really uncomfortable, how could she move around?"
Jim shrugged. "For what I had planned...."
"Ugh! You're sick. Here, have it back."
Soon Jim was happily smiling again. "Say, you're kinda cute, you wanna go steady?"
"Don't you have a girlfriend, you freak?!"
"Sure, but you'd be an upgrade. Just think of all the things I can do for you!"
"Hm..tell you what, let me borrow this thing, and I'll think about it."
"Oh sure, here's my number, I need to go get my girlfriend her gift."
"...I thought you wanted to dump her?"
He gave her a look like he was talking to an idiot. "Uh, yeah, but you're 'thinking about it' so until then, I'm still with her."
Men!
"Fine, fine, go explode her boobs or whatever, shoo!"
He laughed evilly and left.
Leaving her looking at the gun. "Kyle Perkins, you're in trouble."
