Serum

My name is Katie. I am 18 years old and in my final year of high school.

To earn money I work at a local fast food outlet. We are in the middle of what is called a tech park, surrounded by lots of scientific and technology companies. At first I liked this because it meant that most of our clients were smarter than your average fast food customers.

But then came Derrick. I didn't like him from the start. Every time he came in he always wanted to be served by me even though I am the night manager. I may be only 18 but the company is still racist enough to promote the youngest and most inexperienced member of the team if she happens to be white. Having blonde hair, blue eyes and large breasts helps too.

Anyway Derrick would always ask for me by name. When I came out to serve him he would spend the whole time staring at my breasts, almost drooling. Strangest of all was the time he asked me to say "O" for him.

"O?" I asked and as I did he raised his mobile and took a photo! What a crackpot. I didn't want to think about why he wanted a photo of my lips forming the letter O!

One night last week as I finished my shift around midnight I saw him as I walked through the car park. I started to walk faster as he approached me, uncomfortable with the way he watched my breasts jiggle as I walked.

Suddenly he ran for me and as he caught up to me he stabbed a syringe into my arm. I staggered forward for a moment. He caught me by the breasts as I fell and I passed out.

When I woke I was strapped to a bed and Derrick was sitting beside me. I was naked and he was masturbating as he fondled my breasts.

"Oh good," he said like a doctor to a patient but continuing to masturbate. "You are awake. Now listen carefully - your life depends on these words. I have implanted you with four devices. One is a small explosive in your skull that will detonate and kill you when I activate it. Another is a tracking device so I will know where you are at all times. A third is a radio reciever in your ear so I will be able to communicate with you. The last is not so much a device but a serum. It has caused certain changes to occur in your body that without an antidote will kill you. The antidote is 100 loads of sperm to be taken within one week. If you fail to swallow 100 loads of sperm within that time you will die."

Suddenly he straddled me and pushed his penis into my face. I tried to turn away but he rubbed his cock over the side of my face.

"You're a good girl I know," he said. "So you've not seen one of these before. It is called a cock but to you it is a lifesaver. Suck it long enough and sperm will fill your mouth. Swallow 100 loads and you live. After one week my explosive will automatically become inactive. After one week if you haven't swallowed 100 times you will die. Go to the police within that week and I will detonate the explosive. If you do not go to work as normal I detonate the explosive."

He held my nose so I had to open my mouth to breathe then pushed his cock into my mouth. He started thrusting it inside, still holding my nose closed. I started to panic as I struggled for breath. I thought about biting him but remembered the explosive device and knew I would die if I did. I started to think I might die anyway as I ran out of air but he let go of my nose and pulled out his cock. I gasped desperately for breath until he took my hair in his hands and began to pound my face.

"Look at me, bitch," he ordered. I did my best to look him in the eyes but could barely see him through my tears. I gagged as he held my head down, his cock buried in my throat.

Suddenly he started moaning and I thought maybe I had hurt him somehow but he gripped my head tighter and sperm ejaculated into my mouth and throat.

He must have been preparing for and dreaming of this for some time as I feared I might drown on his cum. Wave after wave flooded into me and I tried hard to swallow it all.

Finally he released me and my head fell back on the bed.

"That is one, bitch," he said. "Ninety-nine to go."

He injected me with something again and I passed out.

When I came too I was in the gutter outside my work. I was in my work uniform and could still taste his cum in my mouth so I knew that not too much time had past since he raped me.

I looked at my watch. It was only a few minutes to six and the start of my shift. I picked myself up, determind not to cry but in a state of shock. I didn't know how much of what he told me was true.

"None, probably," I thought. "Just his mad fantasy."

But at that moment I heard his voice in my ear.

"Hey, bitch," he said. "In case you are wondering if what I said was true watch what happens to that Indian co-worker of yours when you arrive."

I looked around but couldn't see Derrick anywhere but suspected he was watching from somewhere.

I walked into the store and saw the place was almost empty. Just Raj at the counter. Suddenly his head exploded in blood and he fell to the floor. I screamed in terror and as I ran to the phone to call the police I heard Derrick in my head.

"Remember that if you tell the police about me you die. You can call them about Raj but tell them it was a sniper across the street. If you mention me you die instantly. Remember ninety-nine loads. One week."

The police came immediately and the store was closed down for the night while they investigated. I told them nothing about Derrick. I said I saw a sniper across the street who drove off in a white van. They seemed to believe me.

The whole time I spoke to the police Derrick whispered into my ear "99, 99, 99, 99."

One of the policemen offered me a ride home. I accepted at once and knew what I had to do. As we drove home I asked the policeman to pull over into an empty car park. As soon as he stopped I went down on him. He tried to pull me off but I managed to unzip him and pull out his cock.

"Stop, stop," he said trying to push me off. "We can't do this."

But as I wrapped my lips around his cock and began to suck up and down the shaft he stopped trying to push me off and began to push me down.

"Oh God," he said as I sucked. "Oh suck it!"

He grew harder and harder in my mouth and began bucking his hips, forcing his cock further into my throat. I gagged but kept sucking, praying he would cum soon.

But he seemed to enjoy it too much. I am sure he came close to cumming but held back because he didn't want it to end.

Hoping to get him off I began to moan in pleasure as if I liked it. This sent him over the edge.

"I'm going to cum," he cried and tried to push me off but I sucked harder, keeping my lips gripped to his cock. Cum erupted into my mouth and I grimaced at the taste but managed to keep it in my mouth and swallow."

"That was fantastic," he said.

"Please drive me home now," I said, licking cum off my lips.

As we drove away I heard Derrick say "98!"

I woke up the next morning in terror and with only one number in my head - 98! 98 loads of cum to swallow in only seven, no six days now. There was no way I could do it. I was as good as dead.

"Maybe he is bluffing," I thought. But the memory of Raj's head exploding made me realise he wasn't. "I have to try. I am too young to die."

Quickly I dressed into my school uniform of white shirt and blue and white check skirt. For once I was glad my shirt tightly framed my large breasts. Today I needed to attract the boys attention. I unbuttoned the top two buttons, against school rules but I had no time to worry about that. Besides a bit of cleavage might get me some detention and alone with a teacher and then - I stopped myself.

Was I really going to go down on a teacher? They would never agree - it would cost them their job.

"Not doing it will cost me my life," I thought.

I was late so I ran out of the house without even stopping for breakfast. I ran all the way to school trying to think of a way to swallow 98 loads of cum without ruining my reputation.

"Has to be with strangers," I thought. "Not boys at school - they will tell everyone. Maybe a teacher - they'd never tell."

I made it class just in time for science and sat in the front row.

Mr Jones was my science teacher and he gave a bad look as I entered, I guess for having my cleavage showing so much, but he didn't say anything.

I couldn't concentrate throughout the lesson. All I could think about was how was I going to get so much cum so quickly. Before yesterday I'd never given one blowjob and now I had to do 100 in a week!

Suddenly near the end of class I heard the voice of my tormentor in the radio receiver he had planted in my ear.

"This is Derrick, bitch," he said. "98 to go. You had better get moving."

"I'm trying," I heard myself say. "I need more time!"

"More time to do what?" Mr Jones asked.

"Um, nothing," I said. The class burst out laughing.

"You seem very odd today," Mr Jones said. "Come and see me after class.".

"OK," I said.

"Well there's your chance," Derrick said in my ear.

I tried to focus on the lesson after that but it was no good. I knew I had to try and blow my teacher but I also new he would never let me. He was too nice. It would take desperate measures.

After the other students left class I walked over to the door and locked it. I then walked over and knelt in front of Mr Jones.

"What are you doing?" he asked.

"I need to suck your dick," I said. "If you won't let me I am going to scream and then tell everyone you tried to rape me."

"What?!" he yelled.

"You have three seconds Mr Jones," I said. "Your cock in my mouth or jail." I hated myself for what I was saying and wished I could tell him why I had to do this.

"Very good," said Derrick. "You are learning."

Mr Jones started for the door.

"I'll scream if you take one more step," I said.

He froze and turned around, looking at me in disbelief.

"One," I said.

He remained frozen.

"Two," I said.

"But it's wrong," he said. "You're my student."

I opened my mouth to say three.

"Wait," he said. "OK."

Part of me was disappointed how easy it was. I liked Mr Jones and thought he would have clung to his principles longer. Perhaps I was too convincing but maybe he just couldn't resist a blowjob from a big tit schoolgirl.

He unzipped his fly and pulled out his hardening penis.

I crawled forward on my knees and took it into my mouth. Mr Jones was gentle compared to the policeman and Derrick. He let me suck it at my own pace, letting me bob my head up and down without putting his hands on my head or forcing me.

The danger of someone walking in remained real so I decided to try and make him cum fast. Enthusiasm had worked on the cop so I started to moan like his cock tasted good in my mouth.

"Ooh," I moaned. "I love sucking cock!" I bobbed up and down faster and faster, licking the shaft with my tongue and gently caressing his balls with one hand. I could tell he was enjoying it as his cock grew harder and harder in my mouth.

"Ooh, cum for me," I said. "I want to taste it."

I looked up at him and batted my eyes and moaned desperately and saw him begin to shake as his orgasm built.

Suddenly he pushed me away. I fell to the floor as he span around, took a tissue from his desk and came into the tissue.

"No!" I screamed as he wiped himself clean and threw the tissue in the bin. "No I needed to swallow!"

"That is disgusting," he said. "You must never do that. You could catch an STD!".

I reached for the bin and took out the tissue. I tried licking the cum out of the tissue but it had already been absorbed. I had blown Mr Jones for nothing.

"98," Derrick said. I burst into tears.

"Don't cry," Mr Jones said. He zipped himself up and stood, clearly uncomfortable.

"Tomorrow," I said. "First thing. At your house. Be ready because I will be there and this time I have to swallow! Or else I go to the cops."

I stormed out of the classroom and made a dash for my next class. The day went so slowly. I was determined I would not blow another student and as I had all female teachers for the rest of the day there was nothing I could do.

"98," Derrick repeated over and over again all day long. People looked at me strangely but how could I explain.

After school I ran home and quickly had dinner and changed for work.

When I arrived I found Raj had been replaced by some 18 year old Chinese girl.

"I am Rebecca," she said. "The new girl. Somebody from head office called before. They said they are worried about you and offered a weeks leave if you need."

"Don't forget my condition," said Derrick. "You must work!"

"No, I'm OK," I lied. "Work will do me good."

"They also said there is a new promotion next week. They are giving away childrens toys with every purchase."

"A giveaway," I thought. "Perfect. That is what I will do!"

"Oh, OK," I said. "But we have our own give away. A kind of early fathers day thing. Any man who makes a purchase gets a prize."

"What's the prize?" asked Rebecca.

"Um," I said. "That is a secret. In fact it is so secret that only I am allowed to know. We keep it in the storage room. Any man who buys something wins. Send them to the storage area. That is where I will be."

Rebecca looked at me strangely but seemed to accept it.

"Remember," I said. "Men only, no boys and definitely no wives or girlfriends."

I ran to the storage room and took off my shirt and bra and knelt on the floor. I wanted any man who entered to get the idea straight away.

It only took a couple of minutes before there was a knock on the door. To my horror it opened and Rebecca walked in with a sixty five year old man. Rebecca screamed when saw me.

"Rebecca," I yelled. "Send them I said not bring them!"

Shocked, both the man and Rebecca turned and left.

"Damn," I thought. "This is stupid. Anyone could walk in! It will never work.".

I was just about to give up when there was a knock on the door.

"Come in," I said sticking out my tits for one last try.

Three men walked in. All young college types. God knows what they were doing here in the middle of a science and tech park. They were the answer to my prayers and my worst nightmare. I would have to suck them all but at least it was three loads closer to 100.

They all cheered when they saw me and came in, shutting the door behind them.

"What is the prize?" they asked.

"Blowjob each. You have five minutes to cum. You have to cum in my mouth and my mouth only!"

The words came out of me with great shame and I felt myself die a little as they quickly unzipped and thrust their cocks at my face.

I started sucking furiously but not as furiously as they attacked me. They fucked my mouth like they hated me. Each one thrusting it into me like I was a blow up doll and not a person. I gagged as one pushed his eleven inch dick down my throat.

"Thats it bitch, take that dick. You love it you dirty whore. Vomit on it."

They slapped my face and tossed me from dick to dick.

"Only five minutes," I said.

"Shut the fuck up bitch," said one stuffing my mouth with cock. "We won the prize, we take the prize."

I would have bitten them but literally needed their cum to live.

After half an hour of being passed from cock to cock one finally pushed himself all the way into my throat and exploded cum. I drank it greedily and saw another cock aimed at my face beside me. Before he could cum I turned and put my lips around it and swallowed the cum as it burst into my mouth.

I looked around for the last cock but was too late. He stood behind me and exploded into my hair. I felt the cum on my scalp and desperately tried to take it out with my fingers but most of it got tangled up in my hair and lost.

Desperately I licked what I could off my fingers.

"Look at this bitch," said the man who came in my hair. "She can't get enough man juice."

They all laughed.

"I'm getting dinner here every night," said another.

"One week only deal," I said.

One of them slapped me. "Didn't ask your opinion bitch. By the time next week comes you'll be hooked."

They walked out and I looked out on a queue of men forming outside. First in line was my tormentor Derrick, back for another go.

"96," Derrick said. "You have something in your hair."

"No, not you," I said as Derrick walked in to the store room. He closed the door and locked it behind him.

"Yes, me," he said and pulled out his erect cock. "Come on, bitch, you still need to swallow another 96 loads or you'll die. You could say I am doing you a favour."

"No," I said. "I've got a lot of other guys out there. I don't need you."

He pushed his cock against my face. "But those other guys haven't got the remote control for the little bomb in your head have they? Looks like you don't have much choice to me."

I knew he was right but couldn't bring myself to suck the man who was trying to kill me. I pulled away but he gripped my hair and slapped me hard.

"You don't have time to argue," he said. "Those guys out there won't wait forever."

He pushed his cock against my lips and I reluctantly opened my mouth. He pushed his cock down deep into my throat and began to pound my face. I choked on it at once and could feel vomit rising in my throat. I tried to keep it down but he forced his cock in and out so hard my gag reflex kicked in and I puked around his cock. He continued to thrust in and out like nothing had happened and his grip on my head was so strong I could do nothing but let him pound me.

I had hoped he would cum soon but every time I sensed his climax building he would hold still, his cock buried deep in my throat and wait for it to subside.

Then he would start to pound again, pulling my hair and occassionally slapping my face.

After about ten minutes people began banging on the door demanding their go but Derrick just kept pounding away at my face. I was so tempted to just bite him and end it all but deep down I suspected that he wanted me to - was almost daring me to do it to give him the excuse to end my life.

Tears rolled down my eyes. It felt like it was never going to end.

"Oh God, bitch," he said. "I'm never taking my cock out of your throat. It feels so good. Look up at me! Let me see those eyes!"

I looked up at him and could see the hate in his eyes as he picked up his pace. I had to do something to get him to cum. I began to jiggle ever so gently so that my breasts would bounce in time with his thrusts. I could feel them sway from side to side and saw his eyes following them transfixed.

I started to moan as well as this always seemed to work on guys. But again he held still in my throat forcing himself not to cum.

He put his hand on his hip and I noticed his wrist watch. It read 9.30.

"My God," I thought. "He's been at it for over two hours!"

My jaw felt ready to break but he continued to fuck my face. The knocking on the door had ended a while ago now and I felt sure not even Rebecca would still be working. I doubted that she would have told the next shift about our give away.

I was exhausted and began to feel removed from reality as this the worst of all blowjobs went on and on. He was trying to break me, I knew - to make it impossible for me to swallow the 96 loads I still needed for the antidote.

I got another look at his watch later. 11 pm!

Finally, after four hours I felt his climax building. His cock stiffened even harder and he started moaning loudly.

"Oh, yeah, suck it bitch," he screamed. I tensed up for his climax but suddenly he pulled out, took a hankie from his pocket and came on it.

I collapsed on the floor. He had robbed me of four precious hours, nearly broken my jaw and not even let me swallow.

"96," he said zipping up his pants. He walked out and I passed out.
