"Mel, what the fuck are you talking about? I've been a woman my whole life? Did you forget that when you started dating me?" You question.
Still somewhat stunned by what she hears, she looks down at the light in her hands. You notice her looking at it, and go to grab it.
You barely touch the light before she jerks her hand and the flashlight far away from you.
"Babe, please give me that flashlight. It's a very powerful device." You try to warn her, now scared that maybe your entire reality has changed somehow.
"No." She says sternly, looking right into your eyes with a glare. "I just saw what this did to you, and I know you shined it at me before you ate me out."
She gets to her knees and backs up into the corner of the bed, all the while aiming the flashlight directly at you. She looks down fiddles with the knob, turning it to blue. Just as you're about to get to her, the flashlight turns on.
With the angle she was pointing at, and the way you were lunging across your bed towards her, the bright blue beam hit you directly in the crotch. You finally get a grip on the flashlight, hitting the off switch as you do. You wrestle it away from Melissa, run into the bathroom, lock the door, and look to the mirror to assess the damage.
Luckily, your beautiful body was almost exactly the same, except for one small detail: Your cock was a few inches bigger than normal.
Turning the light down to a much dimmer blue, you hear the doorknob wiggling and pounding on the door.
"Stop! I accidentally hit you with the light and made you female while you were looking through your drawers! Then when you lunged to get the light, I think I might have accidentally given you a dick! Please don't use the light!" She desperately calls out to you from the other side of the door.
