"No, don't touch it!" Karl yelled.
Dana yanked her hand back at the sound of his voice. Then she glared at him. "You really don't believe that it will change your gender, do you?" But then she saw it on his face. "You really do, don't you? Karl, come on. Whoever gave you this thing is pulling your leg. There's no such thing as magic."
"Oh yeah?" Karl asked. "Then how do you explain this?" He reached into the box and touched the emerald.
The change was obvious and immediate. Right before Dana's eyes, her fiance began to change. Within ten to twenty seconds, she saw his short brown hair grow longer and longer, down to his shoulders. His face became smooth and soft, without even one remaining hair that would have needed to be shaved. His gray shirt split into two parts, one becoming a bra and the other becoming a tight baby-T shirt with a low neckline, which soon was filled with a pair of D-cup breasts. His underwear shifted and morphed into a pair of panties. And his blue jeans turned into a denim miniskirt. His upper body, as well as his legs and butt, became rounded and feminine. And during the last four to five seconds of his transformation, the bulge that was clearly visible beneath his pants moments earlier disappeared completely. His penis had been replaced with a vagina.
She lusted for ... her? Dana now knew her as Carol, not Karl.
"Hey, it actually worked," Carol said, with her now feminine voice.
Dana just couldn't stop staring at Carol's new ample cleavage. And Carol noticed.
"What are you looking at?" But then she followed Dana's gaze to her chest. Carol noticed lust in Dana's eyes. And then understood what must have happened. Everything that had to do with her, before she became Carol, had changed to match her new persona. Like Karl's jeans turning into a denim miniskirt.
Dana had been turned into a lesbian. Carol was Dana's lover.
