Chapter 21: First Sex Education

Certainly, the feel of her ample breasts in my hand felt good.

Maybe around a D or E cup.

I coolly measured Camilla’s breast size, then released the strength I was applying.

Camilla took a step back and asked with a confident expression.

“How are they? My breasts?”

“They are quite magnificent.”

Even pressing the skin firmly with my finger, the elasticity that pushed back was incomparable to that of a human woman.

As expected of a succubus.

She was practically walking, talking pornography.

As I lingered, regrettably fiddling with my fingers, Camilla proactively approached me.

“If you wish, you may touch them until you are satisfied. That was the contract, after all.”

However, I regained my composure and firmly rejected her offer.

“No, it’s fine. Today is the first day, so it’s better to learn the related terms one by one before direct skin contact.”

Saying that, I sat up in the bed where I had been lying.

Camilla, on the other hand, stood before me in her usual upright posture.

Feeling bothered by that, I patted the seat beside me with my palm.

Camilla hesitated for a moment before saying, “Excuse me,” and sat down next to me.

I looked at her and asked.

“First, I need to check how much sexual knowledge you have. Please answer my questions seriously.”

Camilla nodded seriously.

“Yes. I understand.”

“Then… first off, you know roughly how babies are made, right?”

Camilla made a very displeased expression.

“Do you perhaps think I’m an idiot? I’ve known for a long time that children are conceived when a man and woman have intercourse.”

“Really? Then let me rephrase. Do you know the specifics of how that intercourse is performed?”

Camilla was momentarily speechless, but then, perhaps recalling the passionate lovemaking she had secretly watched between Violet and me a few days ago from inside the closet, she answered with a blush.

“…Isn’t it just inserting the male’s genitals into the female’s?”

I let out an involuntary chuckle.

“You still have it slightly wrong, as expected.”

“What?”

“Just inserting the male’s genitals into the female’s doesn’t result in a baby.”

As I said that, I smacked my fist into my palm.

Pang!

“You have to pound it like this.”

“Pound…!”

Camilla’s expression shifted to one of belated realization.

Honestly, I’m feeling a bit dizzy right now.

I never imagined I’d have to teach such basic knowledge.

First, I decided to correct her unnecessarily sophisticated vocabulary.

“And from now on, call the male genitals ‘penis’, and the female genitals ‘vagina’.”

“Penis and vagina?”

“Sexual intercourse is ultimately an act that requires cooperation between male and female. Using vulgar terms intentionally can be one way to excite each other more easily.”

“Vulgar terms… I understand. I grasp the meaning.”

Perhaps because she was quite quick to learn compared to her innocence, she was absorbing my explanations like a sponge.

That suggests a high level of academic curiosity, but honestly, as the teacher, I didn’t feel particularly enthusiastic.

If anything, it made me feel self-conscious.

But since I couldn’t retract my offer to teach now, I decided to move on to the next chapter.

“Usually, as the penis and vagina rub together and the man and woman feel good, a white fluid called semen is released from the man’s penis. If that enters the woman’s uterus during ovulation and meets the egg in the fallopian tube, the baby implants itself. Did you understand up to this point?”

“Ah, yes. I sort of understand what you’re saying, but this is knowledge I’ve never heard before. Do mages usually learn this sort of thing?”

“No, this is information I know personally.”

Honestly, this is sexual knowledge typically taught in modern times, so there’s no way an ordinary person would know it.

As this is a world where mages actually exist, fields like mathematics and natural sciences have developed accordingly, but they haven’t quite reached cytology yet.

At a time when concepts like dominant and recessive genes and the dangers of incest are only just being grasped, there probably aren’t many people in this world who can approach sexuality with such a biological perspective.

Ignoring Camilla’s strangely admiring gaze, I cleared my throat with a ‘Ahem’.

“Anyway, that’s general sexual knowledge up to this point. Intercourse, or sex, is fundamentally an act performed to create offspring, so I covered that first. Understood?”

“Yes!”

“Now, let’s get to the main point. In nature, not many creatures have sex solely for pleasure rather than procreation. Humans, dolphins, and monkeys are prime examples, and frankly, aside from horns or animal ears, demons living lives similar to humans also engage in sex quite freely.”

Which explains why sexual morals hit rock bottom in this town.

Prostitution is one of the oldest professions, dating back to ancient times, and unless it’s a very small rural village, you’ll find prostitutes selling their bodies for a few coins everywhere.

As for me, I only ever went to places with rigorously verified hygiene since my days in the capital, so it didn’t really matter, but someone without such awareness might have gone to any random establishment.

And then they’d get infected without even knowing how.

I pointed a finger at Camilla, switching to my ‘teacher’ mode rather than ‘maid’, and warned her sternly.

“So don’t sleep around with just anyone. Unless you want to suffer from STDs later.”

It might not be advice someone who makes a living from sex should be giving to a succubus, but I still intended to impart this basic knowledge.

But perhaps hearing this for the first time, Camilla tilted her head.

“STDs?”

“Syphilis is a common one, and although rare, there’s also AIDS, a vicious disease that completely destroys the body’s immune system. If you catch it, there’s no cure, and you can quickly develop complications and die.”

When I gave a few examples deliberately to scare her, Camilla unconsciously swallowed nervously.

“Isn’t there a way to avoid catching such diseases?”

It was a good question, so I nodded and answered.

“There is. It’s by using contraceptives.”

Animal intestines, like those of sheep, cattle, or pigs, have been widely used as condoms since ancient times due to their thinness and durability.

There were also ones made of cloth or leather, but their performance was quite poor.

“Sex is something you do for your own pleasure, but you must never forget that it’s also for the other person’s pleasure. Therefore, always keeping your body clean and maintaining thorough hygiene is the secret to a healthy sex life.”

“…Indeed.”

Seeing Camilla, who now looked like she’d believe me if I said I made fermented soybean paste from red beans, I took a small breath and threw a direct question.

“So, Camilla. Why don’t you masturbate?”

Camilla, who had been seriously engaged in the lesson, suddenly stiffened.

Well, she probably never expected to be asked such a question by a man other than her own in her entire life.

However, it was essential information for the upcoming lesson, and perhaps believing she needed to reveal her vulnerabilities openly to move forward, Camilla answered in a barely audible voice.

“…Because I’m somehow afraid.”

“Afraid?”

This was the first time I’d heard that someone avoided masturbation for such a reason.

I briefly wondered if she was perhaps another demon disguised as a succubus, but no matter how I looked, the bat wings on her back and her heart-shaped tail were indeed the symbols of a succubus.

I sighed softly and spoke.

“Masturbation is by no means a frightening act. In fact, doing it moderately can even be beneficial for your health.”

Camilla slowly shook her head.

“I know the dictionary definition of masturbation, but it’s not as easy as it sounds. When I try to masturbate alone, at some point my hands freeze up like stone out of fear.”

That’s when I realized something was strange.

“What are you afraid of?”

I wondered if she had some kind of trauma, but upon hearing her explanation, Camilla’s fear seemed to stem from a vague apprehension of losing control of her body to pleasure.

After all, since her ultimate goal was to lose her virginity, she couldn’t possibly move on to the next stage if she couldn’t even manage masturbation.

So, after considering other methods, I came up with a good idea.

“You just said earlier that your hands freeze from fear when you try to masturbate alone, right?”

“Huh? Y-yes….”

“Then let’s do this.”

“How so?”

“Masturbate in front of me. And if you really can’t manage, I’ll help you.”

“…….”

Her expression turned rigid.

Well, honestly, even though it was my suggestion, I could understand that reaction.

Asking a woman who wasn’t a friend or lover to show you her masturbating.

I wouldn’t have any right to complain if she slapped me.

However, her hesitation didn’t last long.

“I’ll try.”

“…That’s a commendable resolve.”

Saying that, I subtly gestured towards Camilla with my chin.

It meant to go ahead and try.

Camilla, standing before me, took a deep breath with a determined look, then began to fondle her ample breasts over her maid uniform.

Perhaps she wasn’t wearing undergarments, as the outline of her nipples quickly became apparent through the fabric. Finding even that restrictive, Camilla boldly uncovered the clothing covering her chest.

As a result, two moon-like, white breasts burst forth from her clothes.

Rubbing her erect, pink nipples with one finger while slipping the other hand under her skirt, Camilla looked like a lustful succubus to anyone watching.

Perhaps her pent-up lust had finally exploded, but now that the stage was set, she was skillfully masturbating right in front of me.

Watching Camilla’s erotic display, I felt myself involuntarily becoming aroused.

Honestly, anyone who wouldn’t get excited seeing this scene before their eyes must surely be impotent.

This was a naive succubus, who had guarded her virginity for so long, masturbating for the very first time in her life-where else could one witness such a rare sight?

Seeing the translucent fluid slowly trickle down Camilla’s thighs from beneath her skirt where her hand was hidden, I decided it was time to move to the next stage.
