Karyn aimed the gun at Jon and pulled the trigger. The results were almost immediate. But they weren't the results they were expecting.
Within seconds, Jon's body became more curvacious and soft, his hair grew longer and turned a lighter color, and then he felt as his ass grew plumper and his manhood shrunk and disappeared altogether.
Jon's eyes went wide, as he realized that he was no longer a guy. He was a girl!
And then her breasts started to grow in size until they reached the cup size of DD, as Karyn specified on the device.
Apparently, when Jon specified in his wish that the device could change the size of women's breasts, the stone interpreted that as meaning that the device could only give women a different breast size. Jon wasn't a woman, so the device changed him into a girl first, then gave him the DD-cup breasts!
"Karyn, what happened to me?" Jon asked, in her new higher-pitched voice. "I never wished that the device would turn guys into girls. It's only supposed to change breast sizes!"
