Karyn gasped as she felt her bobs sanking and changing shape, becoming huge pecs, while her entire chest expanded, becoming a manly one. Then, went a massive hairy covering.
She watched the guy across the street, now with big breasts, and his girlfriend was caressing his chest with her fingers, surprised.
"Crap, let's get out of here!" Jon said, and pulled Karyn round the corner in to a neighbouring street and out of sight.
"What're we going to do Jon? I missed the shot! I can't keep this... this chest!" yelled Karyn, moving her feminine hands over her new masculine torso, surprised by the odd sensation of feeling her skin so hairy.
"Well you wanted rid of your old big boobs too," Jon replied. "We can get you other breasts. If that couple saw us they would've figured we were to blame. I must say, I didn't expect them to react to it, I was kinda used to the wishing stone and the way it alters reality, but I don't think this ray gun has the same power!"
"So what now? Try and find someone else's breasts?"
