THE SAMPLE
I was on the first semester of Med School. We had a lot of basic subjects that had few relationship with what we expected from studying Medicine, but laid the foundations for later years.
We had one subject that was called Cell Biology and Hystology, where we studied the cells and how they organized on the different organs. We had the normal lessons in the classroom and practical lessons on a microscope room. We divided in small groups of 20 people and we had a microscope for each one on the room.
One day, at the end of the lesson the professor said " I need a male volunteer from each practice group, I will appreciate your participation. Please, send me an email."
I decided to write an email offering myself unaware of what I would have to do. She responded to the email thanking me for volunteering and summoning me to her office that afternoon.
I was nervous about what she might want, and it was also the first time that I was going to speak to a university professor in her office.
When I arrived there was no one in the hall. I expected to find more volunteers, but there was no one. That made me even more nervous.
I knocked on the door and a voice from inside told me to come in.
"You must be X, thank you so much for volunteering."
"No need, it's a pleasure to help." I said trying to be as polite as possible. "Are there no more volunteers?"
"Yes there are, but I have decided to call you one by one because of the nature of the practice."
I gulped trying to look as calm as possible.
"I don't know if other colleagues have commented to you." She said.
"No, I really have no idea what this is about."
"Well, as I have seen you in class, I know you know that we are explaining the male reproductive organs. To observe the tissues of the organs we use biopsies and autopsy samples as in the rest of the practices, but that is not possible with semen. " My face turned white. "The semen has to be preserved under very specific conditions to be able to be observed properly under the microscope. Unfortunately doing this requires an expense that we cannot afford, so we need a fresh sample for the next practice." I was trying to process what was happening.
"So what do you need from me?" I asked without finishing believing anything that was happening.
"I would like you to produce a semen sample to observe during practice." She said in a totally aseptic tone, as if she was asking me for an eyelash. "It will be completely anonymous and you will be compensated with one more point in the course."
I felt pressured. I volunteered knowing what topic we were discussing in class. I must have linked the lesson with 'a male volunteer' in my head. I thought that surely the rest of the volunteers had done that reasoning before (although I later found out that my case was that of most of us). There was also the extra point in the subject, that would help me for the final exams.
"Okay. How do I do it?" It was the only question that occurred to me.
"You must get the sample by masturbation." She answered obviously and with the same professional attitude that was puzzling me even more. "But first you have to meet a series of requirements."
She took out some papers that already had my information written down and the date set.
"What is this?" I asked for.
"It is an informed consent. It is a document to certify that you agree to freely and voluntarily provide a semen sample for educational purposes and that you will be compensated for this with an extra point in the subject. You should know that you can always revoke it, although we would appreciate it if do not do it less than 24 hours before, since we would need another volunteer and there would be no time to get it. "
Feeling more and more pressured, I signed the document.
"Very well." She continued. "Now I'm going to give you a questionnaire to fill out. It's to make sure you can produce a proper sample."
It was a questionnaire on general health with an excessively detailed section on my sexual health. I felt extremely embarrassed and pressured filling in the questions under the watchful eye of the professor.
The last part of the questionnaire was the most uncomfortable. In the introduction it was explained that it served to rule out fertility problems. The professor instructed me to go behind a screen and use the orchidometer on the shelf. After comparing the three balls that seemed appropriate to me, I finally wrote down 25ml.
"Perfect. Finally, I am going to give you a series of conditions that you must meet. There are three days before the practical session, so you will not be able to ejaculate until then. You should avoid wearing tight underwear, if you do not have it, it is preferable that you do not wear clothes inside." This whole situation seemed surreal to me. "In addition, you must follow a strict diet and perform a series of exercises in the morning and in the afternoon. You have everything in your copy of the informed consent."
I left the office without finishing believing what had happened.
As soon as I got to college, I took off my underpants. Since I had no loose underwear, I had to go commando.
I followed the diet to the letter and did the two daily exercise sessions.
The biggest problem was not wearing underpants. No handjobs, no sex and no underwear is the perfect mix to be constantly stiff in a 18 year old guy. It was easy for me to identify some of the other volunteers as they very often tried to hide their more than obvious boners while going commando.
Finally the day of practice came and I was with a mixture of sexual arousal, embarrassment and nervousness.
First thing in the morning I received an email from the teacher of the practical sessions explaining that I had to access through the outer door that led to the back room of the classroom. This way I could come and go while maintaining my anonymity.
At the appointed time I went to the outer door and rang the bell.
"Hello X, welcome. Come in." The short middle-aged man said kindly.
I put on a shy and nervous smile. We both knew what he was there for and that made for a pretty awkward environment.
The room served as an archive and laboratory for histological samples. It was a windowless space (which I appreciated given the task that led me there), lit by a couple of fluorescent tubes, with an old and worn floor that had clearly never been renovated, and with several shelves containing the samples and the "pieces" preserved in glass cubes. It was, without a doubt, the least erotic place imaginable.
"Well, let me explain how this goes." Said my teacher. "First you're going to take off your pants and underpants, if you're wearing them. Then you're going to go to that pile over there" he pointed to an old white laboratory pile held by old and rusty legs "and you're going to wash well with it. antiseptic soap. You have to wash both your hands and genitals well. You said that you are not circumcised in the questionnaire, so remember to clean the inside of the foreskin and the entire surface of the glans very well. Then you dry very well with the green cloth starting through the glans and the inside of the foreskin and continuing to the base of the penis to end with the testicles. So far everything clear? "
"Y-y-yes" I replied with a trembling voice.
"Okay. Then you can proceed to obtain the sample." He pointed to an old stool with a magazine on it. "You can sit there if you want or do it standing up. You have graphic material if it helps. You cannot use any kind of lubricant or saliva." He took a properly sealed bottle from the pocket of his gown, like the ones used in urinalysis. "Most importantly, collect as much material as possible here. Try not to get hair inside. If some of the material falls outside, do not try to insert it by hand, only the amount of fluid that falls directly into the container works. Understood? "
"I-I-I think so"
"Go for it, champ." He said she with a conspiratorial tone as he patted me on the shoulder. "I'm going to prepare the classroom, when you finish call me."
The teacher went out the door opposite the one I used to enter and closed it.
I put my backpack and coat on the floor next to the stool. I picked up the magazine, it was clearly heavily used, probably by several generations of volunteers, full of wrinkles with some torn leaves and lightly and miraculously held only by the lower staple. As I was afraid, the magazine only includes photos of women, so it would be of little use to me.
As a good medical student, I decided to be as rigorous as possible in the process.
I took off my shoes pushing them with my feet. I decided to keep my socks on to avoid touching the old floor that was surely cleaned with materials that "did not alter the stored samples."
I unbuckled my belt and unzipped my jeans. I took off my pants awkwardly and hopping to keep my balance since I couldn't lean on either side.
Between the cold it was, the strange place I was in and the nerves about what I was going to do, my cock slept, allowing itself to be overcome by gravity. I thought I wouldn't be able to do it.
The next thing I did was take the bottle out of the sealed bag that contained it and put it on a shelf near the stool.
I went to the sink and turned on the tap. To my surprise the water was lukewarm. I washed my hands with the antiseptic soap and water. After that I proceeded to wet the crown jewels. Upon contact with the warm water, I quickly developed a semi.
I poured more soap on my hands and proceeded to lather up my manhood. I started with my nuts and worked my way up the shaft until I got to the head. When I got there, I inserted my right index finger inside my foreskin and proceeded to massage the tip of my tail around carefully to finish with a special dedication to the peehole.
Immediately my prick went hard as steel mockingly defying the laws of gravity. Abstinence and sexual desire were more powerful than all adverse conditions.
After drying the entire package as instructed, I sat with my bare ass on the old stool.
I unscrewed the lid of the bottle to have it ready when I expelled my man juice.
I had no images to inspire me, at least not ones that made me horny, so I used my imagination.
I began to think about those other volunteers that I had identified in the previous days. All of them young guys, 18 years old, with athletic bodies and, judging by the size of the tents they were clumsily trying to hide, with a good tool between their legs.
As I fiercely pulled my cock I thought that they had or were going to do the same. Having to repeat my same steps: taking off his pants, thoroughly washing every millimeter of his luscious manhoods, sitting naked from the waist down on the same old stool, grabbing his beautiful, hard, clean boners, and shaking them until with enormous pleasure post-abstinence pour the contents of their eggs into the small pot.
Thinking of those orgasm partners made me extremely horny. That together with the delicious sensation of my hand against my member after several days of abstinence made the pleasure increase exponentially in a few minutes.
Finally, I felt that electrical sensation making my balls shrink and running my eggplant from base to tip. My legs tensed and my feet spread. I noticed how the blood began to flow with intensity towards my face.
I took the bottle with my left hand and aligned it with the head of my cock, inserting it slightly through the opening of the container so as not to touch the walls or the bottom. I began to feel my penis throb and a significant amount of my special sauce began to flow out of it, leaving me with that incomparable sweet sensation.
I squeezed my urethra to not leave anything and closed my approval to the subject. I was embarrassed to use the cloth I had dried with to wipe off the remains of my cum, so I used one of the sheets of filter paper in the room for that task.
I hurriedly put on my pants and shoes and knocked on the classroom door.
"Here you are" I said handing my embarrassing pleasure to the teacher.
"Right on time, not too early and not too late." The teacher told me, carefully observing the bottle with my semen that I had just delivered. "And it's a good sample, 11ml. Not bad at all, at the moment you have the record this year."
"Thanks." I replied as my face turned red betraying my shame.
"Exit from where you entered and enter through the front door with your companions. This way you will remain anonymous."
I put on my epaulet, grabbed my backpack and went out. Well, the worst was over, I thought. Nothing is further from reality.
Upon entering the classroom, we each went to our preassigned microscope. Next to each microscope we had, as usual, the tissue samples that were to be visualized in the practical session. But this time we also had a microscope slide, a cover and a micropipette.
Then the teacher confirmed my worst fears.
"Hey guys, the first thing we're going to do is study a fresh semen sample." Several giggles began to echo through the classroom. I wanted to die. "Please be respectful as one of your colleagues has voluntarily produced this sample so that all of you can learn."
There were a couple of guys who started clapping and cheering mockingly. Each time I sank deeper into my shame.
"Okay, there's plenty of sample, so there should be for everyone. I'll take 0.5ml first and then pass it on to you."
We passed the pot with my milk one by one. Upon reaching me I got a little nervous, but I think I managed to hide it.
I have to say that most of my colleagues were quite respectful, but a few made comments and jokes when the sample arrived.
At this point he couldn't feel any more embarrassment. Hearing these comments and seeing people fuck, pass and even play with my semen I started to get horny. It was my juice, nobody knew, but I did.
In the rush to deliver my contribution, I forgot to turn up the zip on my jeans. With all that excitement, my little friend woke up and, since I was wearing no underwear, he went out to see the world. Nobody noticed because it was under the table, so I discreetly repositioned it pointing to the left and quietly zipped it up.
Following the teacher's meticulous instructions, we all prepared the sample for the microscope. Then we began to study the sample under a microscope and had to fill in the corresponding task in my practice notebook.
My results were:
-Ejaculated volume: 10ml
-Color: Pearly white
-Licuefaction: complete
-Concentration: 17 million sperm per ml (for this we use a device whose name I do not remember)
-Vitality: 75%
-Motility: 43%
-Morphology: Normal
"We can conclude that it is a high quality semen." It was the only comment the teacher made.
At the end of the session, I went back to college, clumsily trying to hide my stiffness. When I got to my room I jerked off again thinking about how tremendously erotic the experience had been. The volume of cream was less but, even so, it seemed to me that it was too much.
The professor fulfilled her part of the deal and gave us one more point in the final grade to those of us who had been volunteers. People wondered why all ten honors were made by boys, we knew, and I was able to confirm that those whom I suspected were volunteers like me.
Over time I told some friends that I was one of the volunteers and it turned into a funny and very erotic anecdote from which I have produced many more "samples".
