Chapter 12 - Sex Ed for the Young Lady: Practical Edition

Nobles really are the type of creatures to make impossible demands, I thought. "Teach me about sex," she said!

The interior of the carriage was instantly filled with that indescribable, awkward air—like the moment a sex scene starts playing on TV while the whole family is in the living room. Just me, my sister, and the Young Lady in a cramped, locked room.

"Now, won't you listen until I've finished?" 

"Go ahead." 

"For us nobles, one of the most important missions is to produce an heir. If there is no one to inherit the territory passed down through generations, the house will collapse."

Well, that's true, but...

"To do that, one must marry, couple, and give birth to children! I am not so naive that I don't even know that! Babies are not brought by storks, nor are they picked from cabbage patches!!" 

"Milady! Please, calm down!?"

While restraining the excited Young Lady, I pulled the carriage curtains shut to block the windows. Thick curtains wouldn't just block the light; they’d muffle the sound so nothing leaked out!

"Since I was born as the only daughter of a Governor, I must bear many children so they can inherit the land with peace of mind. That is why I must obtain correct sexual knowledge and master it so I can put it into practice!"

The Young Lady was burning with passion. What on earth happened?

"...Actually, until just a few days ago, Milady didn't know the 'correct' way to make a baby...!" 

"Are you serious...?"

I couldn't believe my ears as my sister whispered to me in a hushed voice.

"She apparently really believed in the cabbage patches and storks...! It seems the Governor was intentionally shutting out information. He didn't want to teach his daughter anything 'filthy'..."

Knowing that Governor, I could see it. He was a doting father to a fault.

"Wait, so... the person who planted raw sexual knowledge into this pure, snow-white lady was... you, Big Sis!?" 

"Well, the conversation just kind of went that way, so I accidentally...!"

Don't "accidentally" me. My sister is a sexual pollutant. Just by being near her, a maiden's innocence is overwritten with lewdness!

"No, Caliber provided me with vital information! As I said, I must be the one to produce the next generation of our house! I, who carry my father's blood!"

Yes, very noble of you.

"Therefore, I want to make it one of my goals for this study tour to acquire the sexual knowledge I have lacked until now! It is indispensable for the stability of the house, so it fits my purpose perfectly!" 

"It's hard to argue with because it's technically a sound argument...!" 

"Thus, I wish to hear from you two first, as you are the closest to me and have experience. I couldn't speak freely at the mansion with my father watching, but now that we've departed, it's fine!"

Lady Staff's eyes were sparkling with intensity...

"Please, teach me about sex!" 

"This is an extremely difficult request to answer!"

Normally, I’d just say "Let's try the real thing" and push her down, but she's my employer. Plus, I’d been warned repeatedly by her overprotective father before we left. Can I really pour raw sexual knowledge into her and corrupt her?

"I heard from Caliber that men have something called a 'penis.' Since I have never seen one before, would you mind showing it to me for my future reference?" 

"Big Sis!!"

What the hell are you teaching her, woman!?

It's clear where this is going, but I can't afford to be disrespectful to my new master. What should I do? Then, an idea hit me...

---

"Big Sis and I will have sex." 

"My!"

Fortunately, I’m highly experienced with my sister, and we've reached a level of mastery. I've finished inside her hundreds of times. Thousands, maybe? By having her observe us up close, Lady Staff can grasp the essence of sex.

"We're having sex in front of someone again? I'm a bit hesitant about being seen by someone outside the family..." 

"You don't need that kind of modesty now, Big Sis. If it helps the master we're serving, let's expose our crotches and our shame together."

The carriage we’re in is a complete private room—doors shut, windows curtained. It's actually the best environment for lovers' talk. Plus, the unpaved roads of this fantasy world make the carriage rattle and shake, which is perfect for masking the rhythmic sounds of sex. Moving carriages are surprisingly great sex spots.

"Well then, we should give Milady a lecture before we start." 

"W-Wait, I have to say it!?"

Big Sis hesitated. Since the Young Lady would probably find it easier to understand coming from another woman, I’ll leave the explaining to her. Go on, put all the lewd and vulgar things into words.

"T-Then, Milady, I, the humble Caliber, shall explain sex to you." 

"I look forward to it!"

The student was deadly serious. Well, intercourse is a serious matter, technically.

"Sex is a ritual performed by a man and a woman to obtain children." 

"Yes, I was taught that in the previous 'lesson'!"

A "lesson," huh.

"The specific method of sex is... Hey, Sao, this is more embarrassing than I thought!?" 

"Keep going." 

"You brute! ...Sex is the act of a man and a woman rubbing their genitals together."

Yes, yes, well done, Professor Caliber. Keep that momentum and teach her the risqué parts without reservation.

"Genitals are... the man's 'penis' and the woman's 'pussy'." 

"Penis? Pussy?"

The Young Lady was chanting lewd words! Without even understanding their obscene meaning! To stir things up more, I whispered in my sister's ear.

"T-That's right. Since it's important, let's, uh, repeat it together."

"I understand!" 

"Here we go: Penis, penis, penis, penis..." 

"I understand! Penis, penis, penis, penis..."

As she said it, my sister's face turned beet-red. Talk about backfire.

"N-Next: Pussy, pussy, pussy, pussy...!?" 

"Pussy, pussy, pussy, pussy, pussy, pussy, pussy...!" 

"I can't take it anymore!"

Redder than a boiled octopus, my sister covered her face with both hands.

"I thought I was used to this and didn't have a shred of shame left! Why is this so embarrassing! Milady's pure heart is making me remember the modesty I was supposed to have lost!!"

I'm glad you recovered something important as a human. Sex where you throw away shame and seek each other like beasts is great, but sex where you toy with a blushing partner is also fun. I feel like I'll be able to ravish my sister in a different way from now on.

"Now, I will specifically explain the penis and the pussy...!"

Despite her embarrassment, she continued her master's sex education.

"First, the pussy. This is more familiar to us. ...It's this."

With that, My sister spread her legs. To teach the Young Lady, we had already removed our underwear and exposed our genitals.

"This hole between the legs is the pussy. I’m sure you have one too, Milady?" 

"Yes, I do..."

As she spoke, the Young Lady unconsciously reached for her own crotch.

"As someone without experience, you might not have known why this hole exists... or perhaps you hadn't even noticed its existence. But this pussy exists to take the man's penis inside." 

"Eh!?"

My sister directed the lady's gaze toward my lower half. Watching the two maidens interact, my member was already fully alert and standing tall.

"This is the penis. It is the male reproductive organ." 

"Hiee!? What is this!?"

Having seen an erect penis for the first time in her life, the Young Lady was honestly terrified by its size and sturdiness.

"Isn't it inconvenient for a gentleman to have such a large thing between his legs? It looks very difficult to move!" 

"Well, it's variable depending on the situation...!"

My sister had a similar reaction in the past.

"It's so big and thick... Wait? You said this goes inside the pussy? Is that true? Such a large thing is going to tear through the crotch and enter? There will be blood!" 

"Don't worry. A woman's body is much stronger than we think. Even a cock this big can be swallowed by the pussy without a problem."

With that, My sister straddled my lower half as I sat on the carriage seat.

"Watch closely. ...Nnh ❤️❤️"

With a wet, squelching sound, my tip was swallowed into her flesh. The sensation of the warm meat wrapping around my entire penis was incredible.

"Aha ❤️❤️Ah ❤️❤️How is it, Milady? ❤️❤️The penis went inside the pussy, didn't it? ❤️❤️"

The position was a seated lap-grind. Since the point today was sex education, we chose a position where the junction of the genitals was clearly visible to a third party. In fact, deep within my sister's spread legs, the "lower mouth" greedily licking and sucking my penis must have been a vivid sight for the lady.

"S-Stunning...! Even though a pussy is usually closed tight, it expands this much when the time comes?" 

"You have such a wonderful pussy between your legs too, Milady! ❤️❤️Since you're of age, you could have sex anytime you wanted... Kyuheen! ❤️❤️❤️❤️"

My glans ground against the back of my sister's vagina. Though I hadn't moved yet, the subtle vibrations of the carriage provided her with intermittent stimulation.

"Milady, I have something to add." 

"W-What is it?" 

"Big Sis made it sound easy to take a cock, but it isn't. Before insertion, you have to carefully loosen the female genitals and make the flesh soft, or the penis won't go in." 

"But it went into Caliber?" 

"That's because my sister is a lewd, perverted woman. She thinks about erotic things 24/7, keeping her pussy wet and always ready to accept a man."

My sister tried to protest, but I silenced her by thrusting my hips upward. She's a lewd woman who gets swept away by this level of pleasure and can't say a word.

"So she's a serious person who is always ready for sex so she can bear children and leave an heir! I want to become a lewd, perverted woman like Caliber too!"

The Young Lady's innocence actually hurt my conscience. Meanwhile, my lower half was melting into my sister, so I continued to thrust with the rhythm of the carriage, stimulating our sexual sensations.

"Ahie ❤️❤️Ofu ❤️❤️Oh, oh... ❤️❤️" 

"Keep your moans quiet."

Eventually, even in this cramped room, I was able to build up enough sensation to spill my semen inside my sister.

Splurt, splurt, splurt, splurt...

"Haa, haa... ❤️❤️Milady, semen was just poured into my vagina. I will show you."

My sister tensed her glutes and pulled my penis out, causing the white liquid to pour out of the hole. The Young Lady stared at it, half-terrified and half-enchanted.

"What is this white...? Is it pus?" 

"No. This is semen, the source of babies that comes out of a man's cock. When this is poured deep into the pussy, a child is made." 

"Why is that!?" 

"...I wonder why?"

I guess micro-level talk about sperm and eggs doesn't work in this world. I won't bother explaining it then. It'll just add trouble. Let's just go with "that's how it is."

"Anyway, it's important to have this semen released inside the vagina. Otherwise, you can't have a child." 

"Is that so. How great... the penis and the semen...!"

As the Young Lady watched, a drop of semen dripped from my sister's crotch.

"Ah, the precious semen...!"

Reflexively, she caught the dripping semen in her hand. Unsure of what to do with it... the Young Lady eventually...

"Lick."

...Licked the semen off her palm.
