Her bra

After washing her hands, Mary-Kate left the restroom, and headed towards her next class. It was in a different building, and she didn't have much time to get there.

As she stepped outside, she was greeted by a slight chill in the air, and the hammering of a surprise downpour on the eaves of the building. She took a deep breath through her nose, relishing the scent of the fresh rain. For a moment, it drove her lack of shoes from her mind, and she relaxed. That moment ended quickly, though, as she knew she had to get on her way.

Looking at the torrential downpour, she braced herself for the hundred-meter dash she would have to make to the other building, then stepped out from under the eaves. The pounding rain cut through her thin blouse like a thousand knives, and her first step was straight into a freezing puddle, causing an involuntary shudder to run down her spine. She started jogging towards her next class, grimacing as her soft soles slapped against the cold, wet, concrete of the walkway. She could feel her breasts jiggling, her nipples stiffening involuntarily against her wet blou-

She'd forgotten a bra?! That brought her to a screeching halt in the middle of the walkway, her freezing feet forgotten. She looked down at herself in shock. She couldn't have...she had...she'd forgotten a bra. A slight, involuntary gasp left her lips as she stared at her chest. Her rosy pink nipples peered back at her, hard little nubs that were rather visible through her now nearly-transparent, and rather skintight, blouse. How had she forgotten a bra? She must be dreaming! Her mind tumbled for a moment, before a particularly fat raindrop hit squarely on the tip of her left nipple, the cold, stinging shock jarring her from her thoughts. She had to get inside, and fast!

She crossed one arm over her chest, in equal parts to support her unfettered breasts, conceal the shameful display she was putting on, and prevent any more raindrops from striking her sensitive nipples, and sprinted for the door of the building. Her feet, already rather cold, stung as they forcefully slapped the concrete hard enough for her to hear them over the driving rain. A rosy red tinge rose to her cheeks as she darted past fellow coeds, though they were thankfully distracted by their own efforts to avoid getting too wet themselves.

A few moments later, she burst through the doors of the building, and she scampered into the nearest restroom, thankfully right up the hall from her class, to look in the mirror. She looked more like a wetlook model than anything, with her brunette hair plastered to her scalp, and her blouse and jeans clinging to her curves. As she lowered her arm, all hopes of her dreaming were dashed by the sight of her nipples, clearly visible, tenting the wet, transparent blouse she was wearing.

As much as a part of her wanted to go back to her room, she knew she couldn't. Her next class was a credit she needed to move on with her schooling, and they had an exam today. She'd have to sit in the back and hope for the best. As her cheeks flushed again, she draped her arm across her chest again, and hustled over to her next class, managing to duck into a seat in the back row unnoticed, at least for the moment...
