Authors Notes
This is my first chapter of my erotic story. I know I'm late (or early) for making a NNN story, but I had this idea in my mind for a long time. As you will probably notice, I'm not fluent in writing in English. I'm still learning from reading books, but it will take some time to get better. I will accept any constructive criticism in the comments. If you have any tips or vocabulary that I need to learn, please let me know.
The world I created is a work a of fiction, so it doesn't follow any real life rules. Take everything as it comes, as it doesn't want to be accurate, but to focus on the sauce. Have a nice read :)
------------------------------------
As the sun started rising in the morning sky, it was finally time for the challenge.
On the 31st of October, Claire and her girlfriend Jill had a sex marathon. It started in the morning and ended before dinner. Claire was a tall (close to 7 feet) and strong lady, with a medium sized cleavage and round ass. She was the type of girl who was confident all the time. For example, she always wears tight clothes at the gym, to show her perfect body. However, what she liked the most was that her cock was always visible. Her monster was 10 inches, which was nearly double the average of a male dick. Her girth was around the size of a can of Redbull (6 inches). Her feature attracted the eyes of every girl and boy. Usually they would kick someone for exhibitionism, but her body attracted more clients than the gym itself. Her long shaft was accompanied by a pair of balls big as tennis balls. Meanwhile Jill had every feminine feature maxed. A pair of J-cup tits that were proven to have a gravity field of their own. An ass so huge and firm that if someone started admiring it, they would take hours taking their eyes off. She wasn't as tall as Claire, but she wasn't out of her league. Standing at 6 feet tall, she was probably one of the most beautiful models on the planet.
The day before the challenge, Claire came around 20 times, an a time record for a futa, who has a semen output far larger than males. The intention was to impregnate her girlfriend, but without success. Everytime she tried to reach her womb, she was stopped by the cervix. Jill was extremely unfertile, so to increase the chance by little she had go cum in her womb directly. After all the attempts made, Claire started crying "I'm sorry Jill, but I'm unable to make us have a baby". Jill tried to comfort her "Babe it's not your fault. It's anybody fault. I was born like this and we can't nothing about it, except live with." "You are not helping me you know?" Claire sobbed as she tried to clean her face from the tears. "You know what Claire? I didn't want to resort to this solution, but I think I know how we can have a baby" Jill exclaimed "However, you will have make a great sacrifice Claire".
Claire was all ears "I'm ready no matter what sweety, I will do it because I love you no matter what!" She exclaimed.
"So this method consists in resisting any carnal desires and not nut for a whole month". Claire laughed hearing this "It sounds much easier than I expected".
"We'll see on the first of december" Jill challenged Claire and went to bed after dinner.
-Day 1: an humble beginning
Claire woke up better than ever, knowing that if she succeded in the challenge she would finally have a kid with her love of her life. During the day she didn't feel the urge to jerk off, as she was more focused on her dream coming true. However everything changed as she went the gym. The place was much more crowded than other days, something that Claire liked because she loved being watched by everyone. So she put her incredible tight clothes and started working out. While training, she noticed something strange. Her pants felt more tight than usual around her cock. The veins were now slightly visible, but the first thought that came to mind was that she made a mistake with the washing machine' settings. Everyone's gaze locked on the veins that were pulsating with each heartbeat. Claire was on the verge of going to the toilet and jerk off. She did manage to cool off and leave the gym as a winner. At home no one was expecting her, as Jill was at her parents home for the rest of the week. Claire fell asleep thinking the next day was going to be easier.
Day 2: the realization day
Claire woke up early in the morning with her dick acting as a flag pole. She was used to this sight, however, as she scratched her tired eyes, she noticed something strange: her cock seemed bigger. Precum leaked the entire night while she was sleeping, but it wasn't that much. The bed sheets could have been cleaned by hand. Needless to say, her first thought wasn't about cleaning, but checking if her fuck rod grew in size. She grabbed a measuring tape and gasped when she read the number out loud "11 inches". Fortunately she was 7 feet tall, so a growth spurt of one inch wasn't going to be noticed by others. The first question that came to mind was why it happened. The leaking pre was expect as her balls would have filled with cum by the end of the first day, but her cock growing was unexpected. She thought that maybe it was unrelated and she was going to ask Jill when she would be back. Other than a jog during the afternoon, Claire relaxed at home watching her favourite show 'fixing good' which talked about a chemistry teacher and his student searching for a cure to cancer.
Day 3: the stick won't relax
Today was a gym day, but a little problem came up: Claire cock was hard as a rock. First of all she made a mess while sleeping. She had a wet dream and she spewed out as much pre as the average man would cum. Her meat rod grew in size again: now it was 12 inches. Her girth was close to the one of a can of coke, which made her penis uncomfortable to have between her legs. She noticed something new: her balls were bigger. They got slightly bigger, but it was noticable. First thing she did was calling a doctor for an appointment. Then she went to the gym with her dick still hard.
Her shorts started to not fit anymore. If the python became one inch bigger, then the head would be seen coming out of the pants. Anyway, the rumor spread quickly. As soon as Claire arrived to the gym, nearly a hundred of girls and boys came to watch the show. Everyone was left aghast when they saw that a dick that once was big got even bigger.
Claire loved the feeling of when strangers talked dirty about her, so as soon as she started daydreaming about fucking every girl in the gym, pre started flowing out. She was making a mess for sure, although what attracted the most people was her moaning through every repetition. Some girls got closer to Claire and started tasting her pre, making them instantly wet. She didn't notice anything as she was trying to get a personal record on squats, which she easily did. Everyone gave a round of applause when she managed to squat 200 kilos.
Claire felt stronger than ever before, sk she wanted to try for something higher, until she realized that there were girls consuming her pre while masturbating. This never happened in her life, so she blushed and ran to get a cold shower tl relax her cock. At home she went to sleep after dinner, but the thought of the sluts in the gym made her mind go numb.
Day 4: a strangely relaxing day
Nothing special happened on the fourth day. She obviously got bigger again, with a dick length of 13 inches and a girth of 8.5 inches. Her balls seemed normal, as she managed to not have any wet dream. The next day Claire had an appointment with the doctor, so she spent the entire day relaxing.
Day 5: the beast growls
The fifth day was the hardest to of first five. Her cock had massive growth spurt of 2 inches and it was do large that a hand wasn't enough to grab her whole dick. The biggest problems were her balls. They grew massive as grapefruits and they weighted a lot. The bed was a mess and the precum that came out was enough to fill a glass of water. Before the challenge started, she came that amount. Now she wonders if a toilet would be enough to withstand her cumshot. Something she did notice is that she always wake up thirsty. So obviously she started drinking more water. However she already drank 4 liters of water before the start of November, now she drink double the amount. She needed to go to the toilet. When she started pissing, she felt a pressure far more powerful than ever before. Her urethra gap expanded to let a flow of piss go into the toilet, however it was so strong it splashed everywhere. This was a reaction of all the fluids she was drinking during the day. She started cleaning, but halfway through she realized she was going to be late to the appointment.
She entered the futanari specialized building in a rush: she was very late. Claire asked the receptionist if they were going to visit her. The answer was positive, although she would need to wait more as another patient was moved to fill her missed appointment. While in the waiting room, she noticed some infos about futa. As the third sex that appeared on the globe, they were an enhanced version of the humans species. They had both sexes at once which made the other sex redundant. Their sex organs were bigger than the regular ones. For example a dick of a futa averaged 8.5 inches, while the penis of a man averaged at best 5.5 inches. Futanari produced 20 times the semen of a male man, as their testicles have the ability to compress semen beyond imagination. Sometimes a futa's testicle could weight around 500 grams. At the start of the challenge, Claire was already beyond these parameters. Now she destroyed them.
While immersed in the reading, the nurse called her name. She stood up immediately and was accompanied in the visiting room. The nurse looked nothing like you would expect from a nurse. She was short, but built like tank. I would never wish for anyone to have her as a nurse.
The first she does is introducing me to the doctor: "Dr. Van Honn, Claire has finally arrived." She yelled. " Yes Claudia, you can go out now" the doctor ordered.
"Hello miss Claire, how are you doing?" The doctor asked "I could be better" I answered. She asked why so I showed my "little" problem.
Dr: "Holy cow Claire, that's surely a problem"
Claire: "It was smaller before, but it's now growing faster and faster each day"
Dr: "When did the growth started"
Claire: "On the first of november, when I started that stupid challenge"
Dr: "Oh, I see now. You started the famous challenge about not ejaculating for a whole month. Why did you do so?
Claire: "My girlfriend suggested it. We had and hard time trying to have a kid, so she heard that his was going to be the only way"
Dr: " I see. What's your girlfriend is talking about is true, however it can cause some problems"
Claire: "I can see that"
Dr: "It seems that you are different from other cases though. Can you lend me your original measurements"
Claire: "Okay..."
