A short time ago, you had purchased this flashlight from the magic shop.
-----
Pulling the flashlight out of its box, you notice a little slip of folded paper packed inside. The paper appears to be the operating instructions. Pulling it out of the box, you unfold it and give it a once-over. There is a diagram of the flashlight, and it shows how the top rim of the light can be rotated toward blue or pink in various gradations of intensity. There is also a slider which changes the focus of the beam to be wide or narrow. At the bottom of the flashlight is a little dial that is surrounded by two-letter settings around its circumference.
By default the dial's arrow points toward the top of the flashlight toward the setting marked "nm".
Glancing through the instructions you notice that "nm" means normal. In this setting the beam of light will transform anything it touches to be more masculine or more feminine, depending on the color and intensity that the light is set to. At this default the light will affect both inanimate and organic targets caught in it.
Based on this information the next two settings were easily guessed. The "in" setting transforms only inanimate objects and the "or" setting transforms only organic targets, without affecting inanimate objects in the light.
The "sp" setting changes the sexual preference to be that of the color shined. When at this setting the pink does not cancel the blue. A strong light will make one more sexually attracted to either men or women, while a weak light will decrease the attraction toward men or women. Applying both blue and pink lights at high intensity will make someone into a bisexual nymphomaniac, whereas using both lights at the lowest setting will make someone asexual.
The "mi" setting makes those caught in the beam think more or less like a man or woman, depending on the color and intensity of the beam.
The "rl" setting is a relationship creator. You can use the blue light on one individual followed by the pink light on a different individual. This will transform both parties to be in a relationship with each other, with the intensity affecting how strong/long the relationship is.
If the light's rim is turned to be exactly in the middle between pink and blue, it will shine with a white light which resets things to how they were before the light influenced them.
Lastly, there is a single switch with two settings near the dial with markings of "a" and "u", which stand for "aware" and "unaware". This affects whether the target is aware that any changes have occurred. When set to unaware, only the user will be aware of any changes, and in fact will be the only one even able to perceive the beam of light. Others will simply not take notice of it. When set to aware, any parties present at the time of change will notice the change, but due to reality shifting, those who do not witness the change will still not realize that it happened. Parties present will also be able to detect the light.
The instructions go on to say that regardless of awareness, the universe will rearrange itself to accommodate any changes made by the flashlight so as to affect reality in the least obtrusive way possible.

Now you have given the flashlight its first test on your friend Gene. It certainly seemed to work. Deciding to change Gene a bit more, you set the dial to "nm" and the light to a high pink setting and sweep it across Gene's legs and feet, up around his hips and butt, and over his chest, arms, and face. You take especial care to avoid his crotch. Gene's form changes to be that of a beautiful young woman with feminine legs and arms, wide hips, plump and sexy rear-end, voluptuous D-cup breasts, angelic face, and long, blonde, feminine hair. His clothes change into a simple but beautiful summer dress with high-heeled sandals. It is clear also that a bra and panties have replaced his old underwear.
You narrow the beam, rotate the dial to "or", and switch the light to a high blue setting and shine it on his crotch alone. You know that a massive cock is growing inside Gene's panties.
Gene doesn't notice anything and talks to you as any other time. "Hey man, good to see you! I was going to meet Melissa here for a date. Have you seen her?"
"Nope," you reply. "Oh is that her now?" You spy a cute girl coming toward you and Gene.
"Hi Gene," said the girl, who was wearing tight sexy jeans and a pink feminine blouse. "You sure did dress nicely just to go out with me! You look great!"
Gene blushed. "Thanks, Melissa," he said.
Thinking quickly you leave the flashlight as you had it (strong blue with "or") and shine it on Melissa's crotch as well. You can see her tight pants bulge from the big package underneath. Gene seemed to notice the bulge and said "And you're looking sexy as ever, Melissa."
"Thanks, babe!" said Melissa.
Finally, as the two talk you shine a bright blue light and a bright pink light in turn with the dial set to "sp" over both Gene and Melissa. The bulge in Melissa's pants grows and moves up, and her erection pops out from the edge of her pants, covered only by her blouse. You can see Gene's dress is tenting as well.
Lastly you set the dial to "rl" and shine a bright blue light on Melissa, then a bright pink light on Gene. Their faces change to show their casual interest has become intense longing. You also notice a ring has appeared on each of their fingers and you realize that the relationship strength you set must have made them become married.
The two embrace and share a deep kiss together, which quickly becomes a brief make-out session. Melissa then broke the kiss and said to Gene "Why don't we screw dinner and head back home to fuck!"
"Ooh, I was hoping you'd ask!" said Gene. "But only if I get to be on bottom first!"
Melissa replied "Okay, but only if you wear that little princess outfit that looks so sexy on you!"
"You got it, love!" said Gene. And the two ran off to head home.
