It made sense to her now that blue would turn her into a male... whatever 'making sense' made in this situation. Blue was, traditionally, the color of boys. Looking over the rest of the shirts however, she could not even begin to guess what they all did. The numerous plain colors, various patterns, and the different kinds of shirts could each mean any number of things. Was a red shirt going to make her stop like it was a stop sign? Or maybe it would turn her into a bull that charges at anything red. Maybe it made herskin bloody. The possibilities were endless.
She stepped over to her desk and grabbed a notepad and pencil. On it, she wrote, "Blue = Male," and put it down. It only made sense at this point to start making a list. There were so many shirts here that a reference would absolutely be necessary. What if she found one she liked? Maybe even one she could wear in public without being considered a freak? It would be nice to know which one to grab when the mood struck.
From where she was, she grabbed the closest shirt, a purple shirt with a black X across the chest. Again, she wondered at what this shirt could possibly do. Purple was a royal color in the past, maybe it would adorn her in queenly regalia. But the X meant something to, she was sure of it.
But enough guessing; it was time to find out.
She was still naked, having not returned to wearing anything after taking off the blue shirt. Her door was locked though, so she had nothing to worry about. And the last thing she wanted to do was ruin a good pair of pants by growing a tail or something. So she pulled the shirt on, confident she wasn't about to destroy any clothing.
The strange feeling struck, and it was definitely concentrated in her chest, right between her breasts. When she looked down, she could only widen your eyes. "Oh," she muttered. That's what this one did. She had a third breast, right in between her usual two. The front of the shirt did not look like it was stretched out, but was nicely fitting. Whoever had made these shirts had done so with their transformation powers in mind.
She reached up, still in partial disbelief at what she was seeing. She wished she could pull the shirt off and see her new addition plainly. But if this shirt behaved like the other, then the transformation would disappear as soon as the shirt was off. Until she figured out something else, she would just have to use another sense beside sight.
Her hand went up under her shirt, her palm coming up to meet the underside of her new breast. She shivered as she made contact, a pleasant chill running through her from shock, amazement, and just a hint of excitement.
If only she could actually see it. She pulled her hand out and pressed both into her double cleavage, making the shirt show the shape of her third breast. Finally, she reached up and pulled the collar out, pressing her chin to her neck to look down. There it was. It wasn't the best view, but it was a view. It was definitely different from her normal two; it was symmetrical, for one thing, with the nipple right in the center point straight out. It was hard to tell from her angle, but it may have even been positioned just a bit lower. Her normal breasts had not changed, aside from being pushed aside to make room for her new addition.
"That's weird. And awesome," she muttered. After a few moments of studying her transformation, she dropped her collar and looked up. She walked back to her desk and picked up the notepad once more, jotting down the shirt's description and its effect. With that done, her eyes returned to the plentiful number of shirts on her bed. As she moved to grab the next closest one however, an idea occurred. Pulling the shirt up over her head removed the transformation, but what would happen if she cut the shirt off. Or maybe, on a less severe course of action, cut down the collar so that she could get out through it instead of just pulling it off.
She weighed her options.
