The Marquis’ Eldest Son’s Lascivious Story
chapter-73

When I opened a window after I finished dinner and returned to my room, I felt just a slight chill from the autumn night breeze as the days became a lot cooler.

After I wrote for a while at the desk in my room, Fanny came into the room while she was dressed in her autumn pajamas. The white one-piece pajamas made with silk really suited her well.

「Big Brother」

Ever since Fanny found out that mother is coming back from the royal capital, she has been in a good mood constantly. Her smile that is in the process of changing from a girl's to a woman's has the charm of both sides, so I was unintentionally captivated by it.

I had a servant prepare a chair for Fanny, then I decided to read books to her and talk to her like usual as we sat side by side at the desk.

「I wonder if mother is around here right now?」

Fanny said as she pointed at the map of the continent in a book that just happened to be open. She was like this when grandfather was coming back too. When Fanny can't wait for somebody to return, she likes to look at a map and think about where they are.

Maybe she had been looking at a map when I was in Nambonan city as well. I stroked her hair as I imagined the scene of her doing that.

「Let's see…」

There are many different types of maps that show each territory and each country's borders, but there is only one type of map that covers the entire continent of Elluo. That type of map was created by the Synod with the enormous help from the bravest adventurers of the time during the Synod's golden age, a time when they had full authority.

It's an extremely rare map that included the detailed landscape of the northern part of the continent that was covered by a field, the so-called great land of fog that even those adventurers would hesitate to enter.

I pointed at the royal capital of the Levios kingdom that's located on the eastern part of the continent.

「Here is the royal capital, right?」

「Yes」

Then I moved my finger left and immediately pointed at the big river that was to the west of it. There are 7 large rivers on this continent, and this river is one of them.

Judging from the content of mom's letter and the date it arrived, I can assume that mother has already crossed that river.

「I'm sure that she has already crossed this big river」

It would be nice if she could just go in a straight line back to our territory, but it's not that simple.

Since it would create trouble if she goes through the territory of nobles who aren't friendly to our family, as long as it's not an emergency, she will only go through areas owned by nobles who we have a good relationship with.

Because of that, she is on a bit of a detour.

「She said in the letter that she will be returning from this path…」

I moved my finger in a zigzag as I went further west on the map.

Then, I stopped moving my finger before another large river like before.

「I think she would be around somewhere here right now」

「Wow…! Then she's almost back already」

Once she gets past that big river, she'll already be back in our territory.

Fanny's voice livened up as she smiled brightly. She seems really happy.

「I hope that the water of that river isn't rising so she could cross there though」

「They can't cross if the water rises?」

「If the water rises to the point that it'll flood, it'll be dangerous even for big ships」

Unlike the large river near the royal capital, the river near our territory gets its water from Mount Erekthion.

There are 5 large rivers that have Mount Erekthion as their water source, and the secret to supplying that amount of water lies at the bottom of the mountain.

The vast field that covered the foot of the mountain seems to be always in the harsh environment of violent rainstorms.

I don't quite understand the phenomenon of rain being created from nothing, but that's what a field is.

In any case, the massive amount of rainwater created by the fog of that field is something that's necessary for the existence of those rivers.

The rivers often flooded when the rain got too heavy, but it wasn't all bad because thanks to that, fertile soil is carried from upstream, producing a rich land that's good for crops. It's like the blessing of the Nile river of Earth in my past life.

「If the current looks strong, she'll probably go a bit south and cross the river at a spot where the river is narrower. Since she will be in the Silopea family's territory if she does that, I wonder if she'll be a little late」

I moved my finger a bit lower on the map and pointed at a spot where the width of the river is narrower, then I slid my finger left to motion the crossing of the river.

The area my finger landed on after that is the territory under Earl Silopea. That���s where my cousin Plume lives.

If mother is going through their territory, she will probably spend a night there at their castle. That's because Plume is my mother's niece.

「I wonder if Plume-oneesama is doing well. Instead of just exchanging letters with her, I want to see her in person」

「Yeah. I wish she'd come visit us sometime」

「Yes. I have lots I want to talk to Plume-oneesama about」

Plume had lived in the castle of Nyuneri for about a year in the past before, so Fanny had grown quite attached to her.

I gently pulled Fanny's head to my chest and hugged her since she looked a bit lonely, and then I placed my chin on her head.

「Big brother, are you going to Nambonan again? I will be so lonely」

Fanny pressed the back of her head strongly on my chest. The sweet scent of soap drifted from her glossy hair.

「Don't worry, I'm not going to stay there as long as I did last time. Probably」

��Mm. Brother, please come back soon, okay?」

Fanny looked up at me with her clear blue eyes.

I feel like her thin, delicate pink lips were drawing me in.

「Yeah. I'll come back right away after I finish what I need to do there. Now…it's about time for bed. What do you want to do, Fanny?」

I asked her if she wants to sleep in my room or go back to her own room.

「Hehe, big brother」

Fanny did not answer my question and just rubbed her head on me.

It seems that she wants me to carry her to the bed.

「You're still such a child, Fanny. Alright」

After I returned the books back to the drawer of the desk, I put my one hand around her back, one hand behind her knees and carried her princess style.

Since the servants quickly pulled the blanket on the bed to make some space for us, I gently let Fanny down there and then I lay down next to her as well.

「Young master, young lady, since it's cold tonight, we have prepared a new blanket for you. Please let us know if you get too hot」

「Okay」

As we went deeper into autumn, our number of blankets increased.

The two servants worked together and put another blanket over me and Fanny. Are there feathers inside? The blanket is big and fluffy.

I confirmed that the servant who was tasked with being the first one to take turns watching over us when we sleep was sitting down on a chair next to the bed.

「Good night, Fanny」

「Yes. Good night, big brother」

As I stroked Fanny's head, I turned off the illumination spell.

The only light left that shined in the room was the moonlight, and only the sounds of breathing gently echoed in the silent room.

After some time, I began to hear Fanny's cute breathing coming from next to me after she fell asleep.

I turned and glanced at her face as she clung onto me in her sleep.

「Mmm...」

When I gently touched her cheek, I felt a soft squishiness.

I poked her cheek a few times and made sure that she was completely asleep.

Since I always touch her cheeks, the servant who was watching us from next to the bed didn't have any special reactions.

I quietly moved my other hand under the blanket.

Thanks to the fluffy blanket, the servant did not notice my hand moving under there.

I gently moved to put that hand around Fanny's waist, but she continued to be sound asleep. There was no reaction at all.

I stopped moving the hand that I was touching her cheek with and pretended to fall asleep myself.

Then, I moved my hand that was on her waist a bit down and touched her butt. I'm not groping her though. So that in the unlikely event that she wakes up, I can just say that my hand slipped there.

「Zzzz...」

While constantly checking to see if Fanny was still asleep, I continued to touch her butt.

How do I put this? I feel like a molester. It feels so exciting.

Secretly touching her small, elastic, and healthy butt had a nice spicy thrill to it. It's an amazing feeling.

For the next little while, I enjoyed the feel of my beloved little sister's butt.

Since I'm afraid of things becoming weird if I touch her too much, I shook off the feeling of wanting to keep going and took my hand off her butt.

「*Fuu...*」

With both of my hands out of the blanket, I played with her cheeks that are okay to touch as I fell asleep.

The next morning, Fanny's face was right in front of mine when I opened my eyes.

I instinctively felt like giving her a wake-up kiss, but I unintentionally made eye contact with the servant next to my bed.

「Mnn...」

I looked at Fanny's face that was young yet had a nice set of features.

When I was thinking that her hair and her long blue eyelashes that were the same as mine were beautiful, she woke up as if she responded to my gaze.

「Mmm…big brother」

「Good morning, Fanny」

「…Yes. Good morning…」

With a still sleepy expression on her face, she looked at me with a pair of clear blue eyes.

As I stroked her bed hair, her beautiful eyes closed again.

「Fanny. It's morning already」

「Mmmm…I'm still sleepy…? Hm…?」

Suddenly, Fanny opened her eyes again and quickly put her hand in the blanket.

Her sleeping face gradually changed into a face of worry.

「Fanny?」

「Big brother…for some reason…something feels wrong?」

I did touch her butt, but I didn't do anything like sticking my hand into her underwear.

Naturally, I didn't ejaculate or anything either, so there's no way she would have semen on her butt or something like that.

「Young lady. What seems to be the problem?」

The servant noticed something wrong about Fanny and approached us.

I became worried too, so I decided to flip the blanket over with the intention of getting up.

「Is this…?」

「Kyaaa!」

When I started to pull the blanket off, I saw both my body and Fanny's.

My pajamas were the same as when I went to bed last night, but there was something clearly different about Fanny's. The crotch area of her pajamas was dyed in a blackish-red color. It's probably dried blood.

It was really standing out because her pajamas were white and the blood's blackish red.

「Ahhh…! B-brother…! Please don't look…! Ahh… No…!」

After the servant saw Fanny covering her face with her hands, the servant panicked and looked under the blanket.

Then he probably got the gist of what happened, so he went to call a female servant over.

「Young master, I'm very sorry, but please go to another room. Young lady seems to be not feeling well…」

It's not very often that I get kicked out of my own bedroom.

I was a bit hesitant on leaving Fanny while she was crying with her shoulders shaking, but since she told me to not look at her right now, it's probably better if I'm not here.

「Okay. I'll leave」

I don't think she wants people to see her blood-stained clothes, so I carefully got out of the bed while lifting the blanket as little as possible.

After the servant guided me out of the room, a female servant that exclusively looks after Fanny entered my room together with the head maid.

Since the other servants who took turns watching us sleep had to also leave the room, they guided me to another room.

「*Haaahhh…*」

I calmed down after I took a sip of the tea that I had the servants make me.

My heart was still beating a bit fast after seeing her blood-stained clothes first thing in the morning right after I woke up.

After some time, the head maid came to explain Fanny's body condition to me.

Basically, Fanny had her first period.

She had already been taught about her first period and how menstruation works before, but it seems that she was surprised because it happened all of a sudden.

She has regained her composure now after she had some alone time with her personal maid.

And apparently, Fanny had received quite a shock because I saw the blood of her first period.

The head maid bowed down to me and earnestly asked me to be careful about how I conduct myself to not upset Fanny any more than that.

I have no intention of hurting Fanny either. I'll watch what I say and how I act.

But still, Fanny's body is now able to bear children huh…

Will we still sleep together? And will I still be satisfied with just touching her butt?

I feel like it would be safer for us to not sleep together when I have pent up urges.
