"Melissa, I need you to do something for me," you say. You hold out the flashlight towards her, and she looks at it in surprise. "I need you to put me back to normal."
"Why can't you just do it yourself?" she asks.
"I just..." you trail off. "I can't. It has to be you."
"Okay," Melissa says slowly."So I just use the blue setting or whatever?"
"Just use the opposite color of whatever you used to change me," you say.
She takes the flashlight and fiddles with it. Then she aims it once more at you and there is a brief blue flash. For Melissa, though, the flash lasts longer as she runs the light up and down the parts of your body that she previously changed. She marvels at the flashlight's power, wondering whether she should play a bit more with it. But your trust is not in vain, and she decides to just remove what she knows she changed. Unfortunately, that means leaving you with a pussy (which your change made her think you always had) and B-cup breasts (which she also thinks you always had).
"Alright, all done," Melissa announces. You look down at your body and nod in satisfaction, feeling familiar with everything. Although there is one disappointment.
"Couldn't you make my boobs any smaller?" you ask. "It's kind of awkward growing up as the only guy with boobs."
"Don't exaggerate," Melissa said. "I thought you said you wanted to be back to normal."
"Yeah, but you could have made some fixes," you point out. "I mean, I gave you the bigger boobs you wanted."
"Wait, what?" Melissa says.
