Her pajamas have been altered

(chapter originally by SpiralFelix at writing.com)

Mackenzie felt the topmost piece of clothing for a moment before realizing it was her underwear. She pulled them up her legs before realizing she had put them on backwards. Ugh, why are these lights still off? After pulling them off she eventually was able to successfully put them on. They seemed tighter than she remembered for some reason.

If the lights were on Mackenzie might have noticed that these weren't the black comfy panties she wore into the bathroom, but were actually a pair of pink skimpier panties that weren't quite her size.

Dismissing the tightness, Mackenzie pulled on her pajama shorts next. After she had them over her hips, she tied the drawstring to keep them secured. She didn't notice the large slits that had been cut along both sides of the shorts. Her pale thighs were still completely in view on her right and left, even showing a bit of the panties she wore.

Finally, Mackenzie picked up her pajama top, a soft, long sleeved shirt with four buttons running up the front. She slid her arms through the sleeves and began buttoning up the front. It took her longer than usual since she had to feel around for each button. The top three buttons eventually closed fine, but the bottom button seemed to be missing, showing just a bit of her stomach. Shoot! Did I break it? Mackenzie thought to herself. She felt around on the ground for a few moments for a spare button before giving up.

She didn't notice that the top button (the one that controlled how much cleavage she was showing: None or Tons) had come undone when she was bent over. In fact, all three buttonholes had been significantly loosened, allowing the buttons to slide free with relative ease.

Mackenzie gathers up her shower supplies and begins to make her way slowly out of the stall. As she blindly shuffles through the bathroom, the lights suddenly come back on. "Oh! Well that's a relief, I guess." Mackenzie says to herself.

A few seconds later another girl enters the bathroom and heads for the showers. She gives Mackenzie an odd look for a moment as she passes. Mackenzie decides to put the entire shower experience out of her mind and exited the bathroom, oblivious to her slightly altered pajamas.

As she exited...
