The Professor and the Semen Extraction Contract
I cursed under my breath. Damn it, Aries must be completely disgusted with me now, right?
Just moments ago, still unable to shake off my questions about the quest window’s sudden disappearance, I had headed toward the Reinhardt palace where Aries was waiting. The quest vanishing didn’t necessarily mean Aries herself would disappear, after all. But the look on her face when I honestly confessed that I had failed to sign up for the same class had been anything but ordinary. I felt bad for thinking it, but she looked exactly like a maiden who had been devoured and then abandoned by some lowlife scumbag. And we weren’t even in any special relationship yet.
In the end, faced with a woman’s obsessive attitude for the first time in my life, I fled the scene like I was running away. It was only after arriving at Professor Emilia’s laboratory that I realized what I had done. I had burned away the last chance I would ever have to fuck my childhood friend.
With no save or load function available in this situation, the only thing I could do was attend the Magic Potions class I had signed up for half out of spite.
Ha… Sayonara, childhood-friend pure-love sex.
Bidding farewell to one of my long-held fantasies—uniform sex with a childhood friend inside the academy—I opened the door to Emilia’s classroom-slash-laboratory and stepped inside.
Inside the lab, seven students who had arrived earlier were already seated, along with the professor in charge of the class, Emilia Baroque.
Shit, they’ve already started.
The moment I boldly swung the classroom door open, all seven students’ attention snapped toward the latecomer who had the audacity to show up after the first class had begun. At the same time, my eyes met Emilia’s as she stood on the podium.
“We will be conducting a total of ten practical sessions together… Ugh?”
Emilia’s words cut off when she noticed me appearing late. Her eyes grew watery. She had probably spent the whole time imagining on her own that I had broken my promise, switched to another class, or ghosted her to escape the plan. It was obvious she had been worrying herself sick.
“I’m sorry, Professor. My name is Arwen Reinhardt, and I’ve enrolled in your class. Something urgent came up and I ended up being late. I’ll make sure to be on time from now on.”
I apologized to Emilia and casually found an empty seat. Even while I was taking out the textbook I had prepared, the other students’ gazes remained fixed on me. I felt like a monkey on display at the zoo.
“From next class onward, anyone who does not arrive on time will be marked as late, so please be careful. That goes for the rest of you as well. Now, I’ll continue with the explanation.”
Having calmed herself somewhat, Emilia had returned from a timid coward who had lost her partner to her proper professor persona. However, even after she told them to pay attention, the whispering among the students never completely stopped. From the back row, I could still hear two girls talking.
“Arwen? Isn’t he related to the vice president?”
“Yeah. Look at that hair color—it’s exactly the same as hers.”
“Then why is he taking Magic Potions? Aren’t the Reinhardt family knights famous for swordsmanship and horsemanship?”
“How should I know? Maybe he’s talented in both sword and magic like Lady Sophia?”
“Idiot. If that were the case, he would have taken a magic class instead of potions.”
This wasn’t a theater. These girls were openly gossiping about the person sitting right in front of them, apparently thinking their voices wouldn’t carry.
“Ahem…”
When I cleared my throat and pretended to turn around, the girls finally shut their yapping mouths.
Damn it, this is so uncomfortable. I wish the class would end already. Since it’s the first day, maybe they’ll just do some orientation and call it a day?
Despite my desperate hopes, the first class of Emilia’s newly opened course, Basic Theory of Magic Potions and Ingredient Preparation, filled every single minute of its one-and-a-half-hour slot.
Emilia was passionately explaining plants none of us had ever heard of, her voice brimming with excitement.
“The Selium flower only grows in the Betel Rainforest located in the western countries of the empire…”
She had mentioned that even with only eight students, this was a new record for enrollment in her class. No wonder she was so thrilled.
“Choosing and preparing ingredients is the foundation of magic potion mastery. You must never take it lightly.”
Emilia moved between the students, guiding them with genuine passion. Despite her earlier worries about being awkward with people, she actually made for a pretty good teacher. Several students looked at her with respect as she answered every question from these complete beginners without hesitation.
Of course, I wasn’t sure if they would still look at her the same way if they knew that just yesterday, right here in this laboratory, she had offered her breasts and pussy as masturbation material to a male student.
Contrary to how much I had wanted it to end quickly, the class was actually quite interesting. It was far better than those major courses where the only entertainment was staring at the professor’s flaring nostrils.
After a simple hands-on practice of grinding mana-infused plants and simmering them in a magic flask, the first day’s lesson came to an end. Despite Emilia’s self-deprecating comments about her unpopular minor subject, the atmosphere remained warm and friendly until the very last moment.
“The next class will be on Thursday at the same time and place. Thank you all for your hard work.”
“Thank you, Professor Emilia. See you next class.”
As soon as class ended, the students gathered their belongings and left the laboratory. But I remained seated. The real secret meeting between me and Emilia was only just beginning.
Once all the students had disappeared, Emilia locked the laboratory door and spoke.
“How could you be late to class, Arwen? I was so worried something might have happened to you!”
“I’m sorry. There was something I absolutely had to take care of…”
In a way, it happened because of you.
More than half the responsibility for me not being able to take the same class as Aries lay with Emilia. But I didn’t bother pointing that out to blame her. After all, I was the one who had delivered the finishing blow to Aries.
“I understand. If you say so, Arwen, then it must be true. Shall we continue yesterday’s discussion?”
Surprisingly, Emilia didn’t press the matter and readily moved on to discussing the sale of the stamina potion. Compared to her attitude when I had demanded to see her breasts, it seemed her trust in me had grown quite a bit.
“You definitely said yesterday that you have connections in the underworld, right?”
“I wouldn’t call it a connection, but I do know where to go to meet someone who can help us.”
“T-then we should take the stamina potion we made yesterday and go right now—”
It looked like Emilia had completely forgotten my warning from yesterday while she slept. She was already trying to rush ahead again. She hurried to her desk, grabbed the potion bottle containing the stamina drug, and brought it over.
I snatched the bottle from her hand and said, “Again! Again! What did I tell you yesterday? You can’t act so hastily.”
At my scolding tone, Emilia shrank back and apologized in a small voice.
“Hic? S-sorry…”
“You mustn’t underestimate people who do business in the underworld. They’re experts at stripping others clean. For people like that, the first meeting is the most important.”
“If the first meeting is so important, then…?”
“We take the initiative. We leave such a strong impression on them that instead of us begging them to sell our product, they end up begging to sell Professor’s goods.”
“That’s amazing, Arwen! How do you know all this?”
“…I learned it from an acquaintance.”
I spoke as if I were impressive, but I couldn’t possibly admit that I had learned it all from watching dramas. She wouldn’t understand even if I told her the truth anyway.
I told Emilia, “First, let’s decide on a name to introduce it to people. Since it’s your creation, Professor, you should name it yourself.”
“Umm… Uhhh…”
Emilia made strange groaning noises—whether she was squeezing out ideas or pus from an infected wound, I couldn’t tell—while scratching her head. After thinking hard for a long time, the result she presented was:
“Um… How about ‘Stamina Bomb,’ since it explodes men’s vitality?”
It was naming sense on the level of an elementary schooler. At times like this, I really couldn’t tell if she was actually smart or not.
“…For a medicine that adult men will take, that name sounds way too much like a children’s toy. Do you have any other candidates?”
“Sorry, hehe. I’m really bad at this kind of thing. Then, since it was only possible thanks to Arwen’s semen, how about you name it?”
Then why did you waste time thinking about it? Still, a name for a stamina potion…
There was only one name I knew. The erectile dysfunction treatment for middle-aged men whose dicks were slowly giving up—Viagra.
Whatever, I can’t be bothered thinking about it. Let’s just go with something similar.
“Viagrak.”
“Huh? What did you just…”
“The name of the stamina potion should be Viagrak.”
“Viagrak… It has a powerful ring to it, both in pronunciation and vibe. Does it have any special meaning?”
“Hmm… It’s an ancient dialect from the now-lost northern region of the empire. It means ‘expansion.’”
Of course, it was complete bullshit I had just made up. But Emilia seemed captivated by the thrilling words “lost” and “ancient.”
“A lost ancient dialect meaning expansion… It fits perfectly with why people want a stamina potion. Let’s go with Viagrak.”
“Good. From now on, the product you create will be called Viagrak.”
The moment we decided on the name for the stamina potion, an item window for the bottle in my hand appeared once again.
◈ Created by Emilia Baroque using the protagonist's high-density mana semen as a catalyst.
◈ Named after an ancient lost dialect meaning "expansion."
The name field that had been blankly empty just yesterday now displayed the name we had just decided on: Viagrak. As a bonus, the description section had gained one additional line of the nonsense I had just spouted.
Now that we had a proper name, it was time to seriously begin production.
“Since students can go out on Saturday four days from now, let’s meet the person who will sell your product then.”
“Saturday… Then I’ll have to make as many as possible before then.”
“How many bottles can you make based on potion vials?”
Emilia answered while writing numbers in the air with her finger.
“Hmm… I can make about twenty bottles per day, so roughly eighty bottles. Of course, it may vary slightly depending on your condition, Arwen.”
“Twenty bottles a day… What’s the current market price for stamina potions?”
“I heard around thirty gold. Though it can go higher when demand is strong.”
Damn rich noble bastards, spending thirty gold on one fuck?
Raibel’s monthly salary, which I had heard directly from her, was about twenty-five gold. These people were burning an entire commoner’s monthly living expenses on a single night of debauchery. If the struggling masses heard this, they would be ready to start a revolution with scythes and hammers.
I had spent seventy gold on Wolfgang’s adult goods, but that had been a life-or-death matter, so it was an exception.
Anyway, twenty bottles a day at roughly thirty gold each, with thirty days remaining… Even after accounting for what the middlemen will take, the quest should be easily completable.
“Good. Then let’s start production right away.”
But even though we needed to make even one more bottle if possible, Emilia was hesitating.
“Um… That is…”
“What is it?”
Emilia swallowed once, then spoke with a stiff expression.
“When you ejaculate… do I have to take my clothes off like yesterday…?”
I smiled at Emilia and answered.
“Today won’t be the same as yesterday.”
“R-really? Of course, no matter how much we’re in a cooperative relationship, there are lines a professor and student should never cross…”
“No, that’s not what I mean. From today onward, I want to use your body directly to masturbate.”
At my answer, Emilia’s face crumpled like someone falling off a cliff.
“My body? N-no way! Just showing my breasts was already enough to make me feel like I was losing my mind from shame!”
Emilia shook her head violently, clearly expressing her refusal. Perhaps remembering yesterday’s heated memories with her student, her face gradually flushed red.
I quietly closed my mouth, slowly raised my hand, and spread my fingers.
“What is this…”
Emilia looked at the four fingers held up before her eyes with a face that said, What the hell is this supposed to mean?
I told her, “We’ll split the total profits four to six. Of course, I take four. This is on the condition that you service me with your body. It’s not a bad deal, is it?”
“A-are you telling me to become a whore who sells her body for money? I’m disappointed in you, Arwen!”
It was the first time since meeting me that Emilia had spoken in such an enraged voice. But I had no intention of backing down here. If she refused, I would simply have to persuade her more sincerely. And naturally, the sincerity I spoke of was money.
“Three to seven.”
“Huh?”
“Even after calculating the cut the middlemen will take, the money we’ll earn in a month is over ten thousand gold. If you receive seven parts of that, Professor, at least seven thousand gold will end up in your hands.”
“S-seven thousand gold…”
When she heard an amount of money too large to refuse, Emilia’s stubbornly resistant eyes began to waver. And finally, she made her decision.
“Fine. I’ll do as you say, Arwen. You must keep your promise, okay? If you break it, I won’t forgive you.”
“Of course. I take three, you take seven. The condition is that you use your body to milk my semen. Deal sealed.”
I held out my hand to Emilia to signal the completion of the transaction. Emilia slowly extended her trembling hand as well.
“Haa… I never thought the day would come when I would sell my body for money… and to a student, no less… Kyaa?!”
I grabbed the hand of the self-mocking Emilia and pulled her toward me. As she let out a cute scream and fell into my arms, her enormous breasts—ones I had only been able to enjoy with my eyes until now—were pressed against my chest and compressed.
Fuck yes. This is it. This is exactly the feeling I wanted.
The softness of Emilia, enough to make one think they were being hugged by a mascot at an amusement park, traveled through my skin and tickled my brain. It was an addictively soft sensation.
“W-wait, Arwen! I’m not mentally prepared yet!”
“It’s fine. Professor, you just need to do whatever I tell you to do.”
I wrapped one arm around her waist so she couldn’t escape and slipped my other hand inside her robe. My fingers immediately found the panties covering her soft ass. Without hesitation, I pulled Emilia’s panties down. In the end, they ended up hanging around her knees instead of covering her pussy.
The panties Emilia was wearing today weren’t the plain white ones I had seen yesterday, but rather black lingerie.
“Heh… You dressed up quite flashily. It couldn’t have been to psych yourself up for the first class, so were you perhaps expecting something like this to happen?”
“Don’t say weird things! T-there’s no way that’s true!”
“Well, it doesn’t matter.”
While Emilia turned her bright red face away, I instantly undid my belt and dropped my pants. I could confidently claim that since my possession, no one could beat me in speed when it came to taking off pants.
My cock, which had been erect ever since it pressed against her breasts, bumped against the spot below her navel where her womb would be.
“Then, Professor, I’ll begin the semen extraction now.”
“This is really just masturbation, right? Not sex? You absolutely cannot put it inside me!”
“Yes, yes, I’ll keep that in mind.”
I gave Emilia a half-hearted reply as I pushed her robe to the side. Then I guided my cock toward where her pussy was waiting. The base of my shaft clung perfectly to her plump labia and clit. It was as if they had become magnets.
Emilia seemed startled by the sudden contact of my cock against her pussy.
“Wait! You clearly said no sex just now…”
“This isn’t sex. This is sumata.”
“S-sumata? What is that?”
“Simply put, it’s when a man and woman rub their genitals together to masturbate. It’s not as good as sex, but it feels pretty amazing, you know?”
“To do something so embarrassing… Ugh, fine, I understand.”
“Good. Then I’ll continue.”
Having run out of arguments once I called it masturbation instead of sex, Emilia obediently surrendered her body to my movements. And so, in the very place where class had just been held, the mutual genital rubbing masturbation between student and female professor began.
While holding Emilia in my arms and moving my hips, my cock brushed against her warm pussy. The moment her thick mound—the one I had wanted to touch since yesterday—entwined with the base of my shaft, an electric pleasure surged through my body.
“Hngh♡ Hnng, hiiik?”
At first, Emilia had kept her mouth tightly shut, but every time my veiny cock rubbed against her pussy, soft moans began to leak out. Of course, I could still tell she was desperately trying to hold them back.
“Since we’ve come this far, you might as well enjoy it comfortably, Professor.”
“Huuuung♡ N-no!”
“Well, if you don’t want to, I can’t force you. Now, stick your tongue out.”
“My tongue? Hngh… Why?”
“You already know why without me having to explain.”
“…”
Emilia quietly stuck out her tongue. I began to lick her dangling tongue. Slurp, sluuuurp. It wasn’t a kiss of lips on lips, but a lewd kiss where only tongues intertwined. The hot saliva flowing from both their tongues dripped down onto Emilia’s breasts.
Time to cum soon.
The stimulation of tasting both Emilia’s upper and lower mouths at the same time had my lower abdomen trembling. I was on the verge of ejaculation. I picked up a glass cup and aligned its opening with my cock. The moment I released my pent-up urge, warm semen gushed out, filling the cup so much that I could feel its weight in my hand.
After the successful first extraction, I released Emilia’s waist, which I had been gripping tightly.
“Haaah… Haaah…”
The moment she was freed from my grasp, Emilia collapsed to the floor, breathing raggedly as if she had just finished running a marathon. I was the one who had been moving my hips hard, though. She was probably more mentally exhausted than physically.
But unfortunately, Emilia didn’t have time to rest. We needed to secure as much product as possible before going out. And so, the full-fledged semen extraction contract between the student and the female professor had officially begun.
