Not very far before she needs to take it off again

Mackenzie had been walking for all of 2 minutes when she hit her limit. The redhead had no idea how the sweater was managing to feel this infuriatingly itchy, but it was absolutely unbearable! She ducked into the nearest building and began frantically looking for a bathroom. When she couldn't find one in the first thirty seconds, Mackenzie knew she couldn't hold out any longer. She settled for the first empty room she could find, seemingly a professor's office, and immediately yanked her shirt off, sending her backpack crashing to the floor in the process.

Mackenzie exhaled deeply at the immediate sense of relief. The topless girl stood there, letting the open air wash over her irritated flesh and relishing the sensation. Wearing that sweater was becoming like ****! She needed to soothe her skin somehow. Mackenzie grabbed the hem of her skirt and tried to use it to begin wiping the sweat from her torso, but she couldn't quite get it high enough. So, Mackenzie unzipped it and stepped out of it, leaving her in just leggings and winter gear, and began using it as a makeshift towel.

"Ahem," a male voice said from behind her. Mackenzie dropped the skirt and spun around to see a middle-aged man wearing glasses standing in the doorway. "Let me guess," he sarcastically said, "Trying to get extra credit, right?"

"N-no!" Mackenzie blurted out, grabbing the sweater off the nearby desk and holding it in front of her bare breasts. But this only sent another wave of pain through her chest and she was **** to pull it away again. "Ow! No I just... The wrong room and I... My sweater, it's... Needed a break and..." she began babbling, blushing at the realization that the professor thought she was attempting to seduce him. It didn't exactly help her incoherent case that she still wasn't covering her boobs.

"I think it's best if you leave," the professor simply said. Mackenzie nodded and began bending down to pick up her fallen skirt. "Now!" he demanded, "Or I'm calling campus security."

That was the absolute LAST thing Mackenzie needed right then. She sprinted past the man and began running through the hall again, reluctantly leaving her skirt behind and completely forgetting the backpack she'd also left in the room. The redhead ran through the halls, feebly trying to cover her bouncing breasts with one arm while holding the damned sweater in the other. The building was nearly empty of students, but Mackenzie happened across two other professors during her topless sprint. Both of the men seemed surprised but not unhappy at the unexpected spectacle. All things considered, a distant part of Mackenzie's mind realized, the halls could have been a lot busier if it weren't the weekend before finals.

Soon she reached the end of the building and resigned herself to the fact that she'd need to venture out into the snow again. Begrudgingly, VERY begrudgingly, Mackenzie pulled the sweater back on and walked out the door. She still had a ways to go before making it back to the safety of the dorms, and the itchy discomfort was already getting to her.
