Elf Tensei Kara no Cheat Kenkoku-ki

Nocturne Extra Vol 04 IF Chapter 5.2-1 Pranking the Little Sister

AN: This story is a possible situation that could have happened in the story. In the end, Cyril managed to restrain himself thanks to making full use of his rationality. Please take into account that this story is unrelated to the main plot. Where his rationality kicked in remains a secret.

The arrival of Yukino, a silver fire fox who I doted on like a younger sister, had brought some changes, one of those was the installation of a bath in our house.

In Erucy, preparing the firewood necessary to heat the water for a bath had always been a hassle, so I had been hesitant to install one. But with the fire fox Yukino around, that problem was solved.

Today, I was taking a bath with Yukino. Lucy was out, and Kuu had mentioned she would cook for us, so we decided to bathe first before dinner was ready.

Despite being twelve years old, Yukino showed no shame around me, which sometimes worried me as her older brother.

「Cyril-niisama, Yukino loves baths.」

Yukino exclaimed in ecstasy as she poured hot water over herself before entering the bathtub.

As I bathed with Yukino, I couldn't help but think about how adorable she was.

For her age, she was well-developed. She was slender overall, yet her chest seemed to be around a B-cup. Her height was on the shorter side, but she had a good figure, with just the right amount of flesh and a slender waist. She was the very picture of a young girl.

「It feels good, doesn't it? Come on in, Yukino.」

「Okay, Yukino is coming.」

As I beckoned her while already in the tub, Yukino entered, wagging her tail as she joined me.

「Cyril-niisama, hug me tight.」

Yukino said this while comfortably nestled between my legs, her back against me, in our usual bathing position.

「Alright, that's fine.」

I leaned over Yukino's shoulder to hug her more closely.

「Cyril-niisama's arms are so firm and strong, they're reassuring.」

She flattened her ears, a gesture she made when she was completely relaxed.

Yukino, her face flushed from the bath, smiled broadly. She looked so adorable that it made my heart flutter a bit.

「Cyril-niisama, the bath feels so good.」

「Ah, yes, it feels good.」

I replied, my voice slightly strained.

Yukino seemed unusually alluring today, and I had been so busy lately that I hadn't done it with Lucy or Kuu for a while, which caused a certain physical reaction.

Calm down, calm down. She's like a little sister to me.

「Hmm, Cyril-niisama. Are you listening to Yukino?」

Yukino pouted cutely when she saw me looking distracted. She tried to turn around to protest, pushing our bodies even closer. Her soft buttocks pressing against my growing son was especially hard for me. She definitely felt it.

「I’m listening, I’m listening so…」

「Cyril-niisama, something hard and hot is poking Yukino’s butt. Yukino will change positions a little.」

Saying that, Yukino lifted her hips a little and let them drop again. She must have thought that if something poked her from behind, she would just have to sit over it to flatten it.

「Higii.」

My son got pinned under her soft bottom. My desperate situation became even worse than before. Yukino, seemingly oblivious to my plight, continued to move her bottom, trying to find a more comfortable position, all the rubbing was making my son feel even more pleasure, deepening my despair.

「Uumm, Yukino still feels it, but Yukino can endure if it’s like this.」

Yukino stopped moving when my penis was under her left cheek, she seemed satisfied with this position.

That was dangerous, I was about to go down a path no sane person should enter.

「You've said several times that you want a baby, right?」

「Yes, Yukino must have a ton of babies or the fire foxes will disappear.」

「Do you know how they are made?」

This question had been on my mind for quite some time. Yukino had asked for a baby several times, but she did it so casually that I doubted she knew the process of making one. If she continued to be ignorant, she might one day be taken advantage of by a bad adult.

「Yukino doesn’t know. Some time ago, Rera said that you and Kuu-neesama were making babies in the old warehouse, so Yukino went there to learn to make them, saw what you were doing, but Yukino didn’t understand.」

Some time ago, Kuu told me that she was being watched by Yukino, this must have been the reason. As expected, she didn’t know. I hated myself for getting horny with this pure child.

「Can you make babies by hugging together naked and going bam bam?」

Yukino asked me with a smile on her face. She probably thought that if her hypothesis was correct, what we were doing would give her a baby eventually.

「Hugging is not enough.」

「Teach Yukino to make babies, Cyril-niisama.」

「…You should have Kuu teach you. I stayed too long in the water and I’m a little dizzy. Let’s get out, Yukino.」

I wasn’t brave enough to teach Yukino how babies are made, I would have Kuu teach her instead. I would have to make it up to Kuu someday. More importantly, I had reached my limit, I needed to go to the bathroom and masturbate.

「No! Yukino wants to keep talking with you.」

It seemed that the princess wasn’t having any of it. She took my hand, which I had tried to keep away from her body, and brought it to her own chest. What a way to destroy all my hard work not trying to touch her in any weird places! My hand touched Yukino’s breast sinking into it, a hard protrusion touched my fingers.

「Kyaa!」

Yukino let out a small cry of surprise, and her skin took on a red tinge not unlike the flush of the bath.

「That felt good, Cyril-niisama.」

She began to brush my hands against her chest, especially around her nipples.

「What is this, Cyril-niisama?

Yukino didn’t know what she was doing, she only knew that it felt good. She didn’t have the knowledge but her body was mature enough to react to the pleasure. Her voice took on a certain sultriness, it was the first time I saw this side of Yukino. The little girl who I always thought of as my little sister, was masturbating in front of me. It was a very immoral and arousing scene. The sound of my saliva running down my throat loudly resounded in my ears.

「Yukino, I’ll help you wash your body.」
