I closed and locked the door behind me. I did not want any zombie to rush into the room. The window was open. A cold breeze was entering the messy room. Clothes, various books and other school furnitures were all over the place, as if someone had been rummaging through the stuff to find something. A girl was lying naked under the window, frantically masturbating. She did not notice me. In fact, she could not notice anything since she was completely lost in her pleasure. It looked like she was cumming every second. However, she stayed silent. She probably had stopped screaming after the first orgasms. I wondered how long a mind could handle pleasure before giving up. She was clearly beyond that point.

Whether she had locked the door herself or someone had locked her in, I was too late. I gave a frustrated kick in the clothes on the floor. It was definitively not a good day. I noticed a book at my feet which was under the clothes I had moved. It looked like a diary. I picked it up and opened it. Maybe I would be able to learn something about what happened.

The first entries were of little interest and only taught me its owner was a girl named Jessica and that she had a boyfriend named Ivan. She had written "Dear diary," at the beginning of each entry. I found it stupid. It was a waste of time. It was not like the diary could answer or something. But I was also finding stupid to write a diary, so I guessed she was just being coherent with herself. I skipped the boring parts and read the last entries.

"Dear diary,

Today, we had to take a vaccine against some kind of flu coming from an Eastern country or something like that. I hate needles, but at least I missed a litterature class. Ivan ditched class to hold my hand until I got to the infirmary. So romantic! He's been getting closer to me lately. I think this relationship is finally going somewhere. And when I mean somewhere I mean the bed. And when I mean the bed I mean sex, not just spoon me. I thought I was gonna kill him when we were both in bed and he suggested that! As if I just wanted to sleep with him instead of... well, sleep with him. Anyway, I can't help but feel a little suspiscious. He's been acting a lot bolder than before. Not that I don't like it. But doesn't it hide something? I hope he doesn't cheat on me. I'd kill him!"

"Dear diary,

Ivan and I finally did it! I'm so excited! And so he was, if you know what I mean. It was amazing! Maybe a bit rough at the beginning, but still (and very) enjoyable. I didn't know this part of him. He was so... manly, not like his usual "I need time" excuse he would always give me. God, I can't count how many times he said that to me. I guess he had the time he needed at last. But I'm a little worried. He wouldn't say a word during... you know. I mean, he didn't even tell me he was coming. Thank goodness I was taking the pill just in case I could get him drunk one night. And his look! Well, it was kinda flattering to see he desired me so much, but... I don't know. It was like he wasn't himself anymore. But maybe I'm just worrying for nothing, as always. Like back then when he took off my clothes, I was so nervous! Even though I was the one who wanted it from the beginning. Shit! I have class. Gotta go."

"Dear diary,

Priscilla is nice and all, but she really should quit lying just to get more attention. You won't believe me but she actually said students had sex with the teacher during her biology lecture! As if anyone wanted to do that old four-eyed schmuck. I don't know what is wrong with people these days. They're all obsessed with sex! Well, it's not like I could give them any lesson. But seriously, what about those rumors about masturbating in class? Maybe I wanted so badly to have sex with my boyfriend but that doesn't make me a weirdo like those who spread rumors like that!"

The next entries were obviously written in a hurry and with a shaken hand.

"Dear diary,

I locked myself in my room. They won't enter that way. It was awful people got mad and guys **** girls and girls **** guys and there was an orgy at the self-service and Ivan he had red eyes but doesn't have red eyes he has blue eyes but he looked me like our first time and he was fucking a girl's brains out and a janitor tried to tried to grab me and he had red eyes also like everyone I want to go home!"

After that, Jessica was not bothering herself with "Dear diary" anymore.

"What the fuck is going on? I can hear people doing dirty stuff out there. People screaming for help too. I'm too afraid to go out. Someone is trying to open the door, I'm so scared."

"I'm horny. It's strange. It never happened to me so suddenly. Am I becoming like them? Please let it not be that!"

"I'm trying so hard not to masturbate. I'm so hot. Took off all my clothes but it's not enough. Maybe I'll just open the window. I need some fresh air."

"Can't find my dildo. Searched everywhere. I bet that slutty Priscilla bitch took it. I told her not to take it without permission. I'll kill her!"

"I fingered myself. I couldn't help it. I had to make it stop. I'm better now but I can feel it's not over."

"I'm fingering myself again as I'm writing this. I wish Ivan was here to fuck me. Ivan, you sucker. I hate you so much."

"I almost unlocked the door. I just wanted to feel better. I wanted someone, anyone to screw me. I'm losing it. I threw the key outside to prevent me from doing it."

"IF ANYONE READS THIS, FUCK ME"

"I'm going crazy. I can't stop touching myself. I don't want to be mad. I don't want to be like them. I'll jump out of the window. I love you, Ivan."

It was the last entry. She must had lost it before jumping. I watched the girl in the room. Was I going to end up like her? Or like the other girls in the corridor? I had been acting pretty slutty lately. It did not look like me. Or, should I say, the former me. I had changed so much in so little time... I had sex with guys I did not know, whose only goal was to have sex again and again. Even though I realized I had changed, I was not as scared as I had think I would. After all, people change and sex did feel good. Remembering all the dirty stuff I had done in only a few hours aroused me greatly and my fingers were soon inside of me. I took off my clothes and rubbed my clitoris with great enthousiasm, among the clothes and books on the floor. I imagined myself getting fucked by multiple men, over and over, the semen flowing, the moans and grunts of sexual satisfaction... I came with an unusual strength, dirtying the floor and myself. I was sleepy. It's funny, I thought. It seems like the more I cum, the better it gets every time. I fell asleep...

I woke up with an uncomfortable feeling between my legs. My pussy was aching, asking to be filled. It was getting cold and dark in the room. The night was falling and the open window let a freezing draught enter the bedroom. I got up and closed it, stumbling because of the mess on the floor several times. Then, I switched on the light. Better. I realized I was naked and I tried to remember what had happened. Memories came back. I had been a naughty girl. And I had loved it. It was... disturbing. As if the person I had been before waking up was not me. I remembered embracing my slut status. Now my thoughts were cleared, the perspective to become a slut scared me. Something was trying to mess up with my personality. And that something was... me. I could already feel the changes occuring: my body was aroused for no reason I was no longer bothered by my nudity. Would not I be cold, I could have left this room in my birthday suit. I was definitely turning into one of them.

I tried not to panick. There had to be a way to reverse the process. If I could find the origin of this crisis, it would help me finding a cure. The diary I had found contained clues, for sure. I read it again carefully, trying to find the trigger. The best lead seemed to be the vaccine. Before this event, some strange behaviors were reported, but they were isolated. After the vaccine, massive hysteria began. My next destination was obvious: the infirmary. I had to hurry while I was still myself if I did not want to be zombified. The problem was that it was just a lead, not a certainty. Finding sane people who had witnessed the beginning of the crisis would be very helpful, and I knew exactly where to find them: on the roof. There was also the problem of directions: I had no idea where the infirmary was. I needed a guide. In the end, I had two options: make a detour by the roof and hope people there would be friendly or go directly to the floors below and hope I would find someone who could help me. In the mean time, I would have to fight my sluttiness as much as possible. I slipped on my clothes and gathered my stuff to go to...
