You quickly used the flashlight in the same setting on her crotch. You notice the girl changes her posture a little bit to make room for a penis, but other than that, nothing seemed to change. "You almost don't even look like a girl," you say, wondering how she will reply. To your surprise, the girl frowns. "I guess... you figured it out," the girl replies.
"Figured what out?" you ask. The girl looks very uncomfortable, as she is thinking about what to say. "I'm... transgender," the girl says. You're somewhat surprised to hear that this is the way reality has 'fixed itself.' "Does that mean," you ask, "that you have a penis?"
The girl nods. "I don't like it either," she says.
You think about what fun things you could do. You got a fun idea. "Say, see this flashlight," you say to the girl as you show her your flashlight, "it's magic."
The girl laughs - it's a cute giggle. "What do you mean?" she asks. "It can change a person's sex," you tell her honestly as you put it on its brightest-pink setting and hand the device to her. "Shine it on part of yourself and see what happens."
Confused, the girl shines the light on her chest. You are surprised when her breasts don't grow bigger at all, but then realize you are affected by the change in reality. "Oh my God," the girl says as she feels her breasts. It was weird to see this girl suddenly touch her breasts as if they weren't there before. The girl then also shines the light on her crotch and you wonder why you ever gave it to her in the first place. You wonder how she is now different from before, but watching the girl feel herself all over is very arousing.
