Karl quickly swept the low pink light across his upper chest a few times not really expecting anything to happen. And at first it seemed like he might be right. It was only after he'd turned the flashlight off and put it on the counter that he noticed that his shirt was hanging a little different. He looked closer and it looked like it was being pushed outward ever so slightly.
Not believing what he was seeing, Karl moved his hand up to touch the unexpected protuberances. It felt like he had breasts! Karl pulled out the collar of his shirt and was greeted by a sight he'd never expect: He really did have breasts. To be fair, they were quite small and undeveloped, perhaps the size one might expect and a girl entering puberty, but they hadn't been there at all a moment before.
"It worked." Karl mumbled to himself forgetting about the old man for a moment.
"Yes, it certainly did. Though I will say it can do much more spectacular changes than that. You had it at a very low pink setting after all. Why don't you try turn it up a notch or two?" the old man suggested.
Karl was kind of scared at the power this flashlight promised to give him. He hesitantly picked the flashlight up again and examined the color intensity dial. He turned the intensity up a few clicks and looked at the old man who nodded encouragement.
Now knowing full well that the flashlight really could change his body, Karl clicked it on again and once more played the feminizing light across his body.
