The following tags are on this extremely fictional story: noncon, rough, mindless, apocalypse, violent. They all truly apply. There's some sharp objects too.
==================================================
I rolled to the side of my desk and scampered for the door to my office. I had planned to escape but what I saw outside caused me to instead slam the door shut and lock it. Mary, one of the office secretaries, who had, just this afternoon, been taking dictation in my other office chair, slammed into the desk, trying to stab me with her bloody pencil. I'd seen where the blood had come from. She'd stabbed Carl repeatedly in the eyes and neck. Through the windows of the office I could see him on his back, bleeding, twitching but otherwise still, joining the other guys in the office down on the floor, dying or dead. Another woman in a mini-skirt slammed into another glass panel of my office. I was surprised it held, but I had my own problem directly in my face.
My secretary Mary had come busting in, her own pencil high, trying to stab me, as I had dived out of the way. Mary was hot. She was middle-aged but tall. I'd hired her for her legs and I think she knew that. Her office "uniform" consisted of a short skirt, cut to just above the knee. When she sat down it came to mid-thigh, revealing even more of her shapely legs. She had blonde hair in a bob and today had worn a white silk blouse which had lost a button in her scuffles. It was now open enough to show her black bra, where her left tit had escaped, her red areola visible against the pale mound, her nipple rock hard. We were staring at each other across the desk.
"What the fuck has gotten into you?" I roared but she didn't respond, just bared her teeth. I looked out the windows to see the women of the office, who outnumbered the men two to one, finish dispatching the rest of our male coworkers. They'd used pencils to stab and computers to bash. Now several of the enraged women were slamming their bodies against the windows to my office. I hit the emergency button on my cell phone but got only a random beeping. What a time to lose service!
