A 30 Year Old Virgin (One Who Haven’t Even Interacted with Women) Took an Exam to Become a Wizard.

Volume 2- Chapter 02: First Bath with My Little Sister

My little sister is 20 years younger than me, at the age of 10. After dinner, she stripped down to her underwear in the living room, ready to take a bath. I think it’s gross to take a bath right after eating, but…

“Again? You just ate.”

Mari-mama scolded her, but…

“It’s good for dieting. If you don’t consume the energy you ate, you’ll become a pig. What are you doing, Onii-chan? Let’s take a bath!”

She pulled on my arm. With me?

“Sugumi, you’re already 10 years old. It’s time to stop taking baths with your brother.”

“It’s fine. I’ve decided that my first time will be with Onii-chan anyway.”

“Boo-hoo-hoo!”

“How dirty.”

The one who blew the contents of his mouth was my dad. I understand. My sister doesn’t know what she’s saying.

“Your brother complex is a problem, isn’t it–“

It’s not a small problem, I think, but whatever. Mari-mama, stop her. Exercise your authority as a mother and stop your sister and me from taking a bath together.

“Only until your 11 years old, okay?. From your next birthday onwards, you can’t do it anymore.”

“Yay, thanks, Mama.”

“Dad, when’s Sugumi’s birthday again? What month, what day?”

“You forgot already? It was last week.”

“I was joking, I was joking. Ha ha”

There’s still a whole year left!

She’s 10 years old, but because she inherited Mari-mama’s genes, she’s still a beautiful little girl. She’s a top-notch lolita.

For an otaku like me, who’s moved by moe, she’s a dangerous poison. She’s shamelessly standing there in her underwear, and my gaze is something that people would take for as public indecency. If I took a photo of this moment, I could sell it for a high price. She radiates that much brilliance. Just saving it on my smartphone would undoubtedly lead to trouble later on.

Being naked together is not something that should be taken lightly, it requires mental preparation. Something could go wrong by accident. The previous me would have probably been used to washing her and taking care of her since she was still a baby, but for me, who just met her, I don’t know our boundaries of skinship. I can’t guarantee that I’ll be able to keep my sanity considering how clingy she gets.

“Um, I think it’s wrong… “

“As always, please take good care of her. Properly wash your dear little sister, Akira.”

My mother, who blocked my escape route, was troubled, but the one who was really troubled was me. Dad and Mari-mama were puzzled by my attitude. Even if I were to say that me having a little sister was because of the goddess’s panty exam, I would for sure get looks of pity from them. The situation probably won’t change.

Sugumi pulled on my arm and said, “Come on.”

I was pulled off the sofa and looked up at my sister, whose eyes were filled with tears.

“Onii-chan, do you not want to take a bath with me?”

“…… I understand. I’ll take a bath with you.”

I took off the last piece of my clothing and became completely naked, and Sugumi, who was already naked, jumped into the bathroom with momentum. I followed her, covering my front with a towel.

“Excuse me… Uwah”

Sugumi removed the nozzle, turned the cock, and began to shower with water before it reached the right temperature.

“It’s too cold!”

“Ahahaha! I caught you again!! You’re still the same as ever, Onii-chan.”

Kahaha, my sister who laughed widely spread her legs wide. She sat in the pool as if she were playing, and she clearly wasn’t ashamed of her body. I was embarrassed by my pure elementary school student’s delusions.

My junior had been standing tall from the beginning, it still isn’t getting smaller… No matter how pure the loli might be, the one observing can’t always have the same thoughts. I can’t seem to let go of the towel.

“Sit down. Wash my hair from behind.”

“Ah, yes, it’s long and beautiful.”

I thought again, managing this long hair must be quite the work.

“Hehe, I’m proud of it. And Onii-chan, don’t poke something weird on my butt just because you’re around! That kind of thing is for the bed sessions.”

“Bufuh”

I take back what I said before. She’s not pure at all.

“Where did you learn that line?”

“From Dad and Mom… Or so I’d like to say, but it’s actually from my friends. Those two have their guards up when I’m around, and they barely even flirt in front of me.”

My little sister, who was defenseless, sat on the bath chair, exposing her back to me. She sits with her small body wedged between her legs and I poured hot water from the shower onto her hair.

“Then, about men and women in general?”

“Sex? Of course. That’s why I’m tempting you, Onii-chan. If I lose my virginity, I want to do it with an adult that I feel safe to be with, you, Onii-chan.”

“……”

She’s kind of what, like, too mature for her age? She doesn’t feel any guilt about incest at all. In other words, she’s a convenient electric massager.

“Then why is it until you’re 11 years old?”

I think it’s only in public baths that parents can take baths with their children of the opposite sex. The age limit is 11 years old or something.

“That’s because Mama’s first menstrual period was at 11 years old.”

So she’s saying it’s okay until it’s possible for her child to get pregnant since she hasn’t yet had her period? But just because it won’t lead to pregnancy doesn’t mean it’s a reason to do it.

It’s like the rules of Japanese monkeys. In some documentary, I saw that the young male monkeys of Japanese monkeys can have sex with adult female monkeys until they ejaculate for the first time. There are no virgins in the monkey mountain. I was jealous of it back then.

“Use the clear bottle for shampoo and conditioner, okay? And remember, use the soap, not the body wash. You always mix them up, Onii-chan.”

When I looked, there were lots of bottles lined up, each with a name tag hanging from it. There were five labeled “Mama” and two labeled “Sugumi.” They all seemed expensive, but there were three with nothing on them. Those cheap ones were for me and dad, lumped together.

“Transparent and squishy huh? Girls use a lot in just one wash.”

“Yeah. It usually goes out in 2 weeks. And because of that my allowance gets cut, mama is so stingy.”

“It’s not all of it, is it?”

It’s a high-class bottle that gives a sense of luxury.

“Of course. If it all went out at the same time, I wouldn’t have anything to use to wash myself. But isn’t 800 yen a month too little? I saw other kids have 3000 yen a month.” (T/N: The amount is indeed too little even for high schoolers, but usually parents fetch their children, so most expenses goes on the parent’s pockets anyway. It’s around 6 bucks for 800 yen, and 20 bucks for 3000 yen.)

“Mari-mama is teaching you about money.”

She’s a wise mother.

I was in the ¥3,000 camp. My dad might have thought that being a single parent was lonely and pitiful. Some of my friends got only ¥200, but they didn’t seem to be struggling. They would save up little by little to buy what they wanted. Compared to me, who spent money recklessly, to just buy everything I want like games, Mari-mama is raising Sugumi properly.

Shampoo and rinsing is over. As I thought, long hair takes time. I’m exhausted.

I lightly showered her body and put her in the bathtub. I washed my hair and body and sat in the bathtub. It took me a third of the time it took to wash my little sister’s hair.

“I’ll get in too.”

Our bathtub is big enough for two adults to sit side by side. It’s plenty of room for Sugumi and me. I tried to get up from the bath chair, but before I could, Sugumi quickly got out of the bathtub, returned the chair to its place, and sat back down. This time, she faced me directly.

“Huh?”

She’s in the fourth or fifth grade of elementary school, but her body is starting to show signs of becoming a woman, with small breasts and erect nipples. Her buttocks have started to gain flesh, and she has the beginnings of a woman. She’s hiding it with her legs together, but she might have pubic hair too.

“Wash my body with soap too.”

She looked up at me with mischievous eyes. She’s obviously teasing me.

“Don’t joke around.”

“Onii-chan, you’re getting bigger.”

My crotch, which hasn’t calmed down yet, is reacting to her naked body and getting bigger.

She glanced at it and decided to take action. She reached out to grab my erect junior, but I slapped her hand away.

“Don’t touch it.”

“You’re stingy. I thought I’d finally do it tonight.”

She sighed regretfully and moved her long hair forward. She turned her body around on the bath chair and showed me her back, which was flawless and smooth.

“Muu… I’ll bear with it for now. In exchange wash me without using a sponge.”

I won’t compromise any further. My determination to not give in is clear in my voice. Well, that enough is fine, but…

I lathered up the soap and started washing the delicate body of the elementary school girl.

Along the way, a pitiful voice leaked out of her. I pretended not to hear it, but there’s a limit to how long I can do so.

“Can’t you hold it in?”

“Your hands are too gentle, Onii-chan. Ahh~”

“……”

I am a human car wash machine. That’s how I see it. I believe I fulfilled my mission until the end. By the time it was over, I was completely exhausted. I ended up dozing off in the bath, choking on the water I swallowed repeatedly.

After getting out of the bath, I collapsed on the futon. My smartphone vibrated. It was a complaint email from my colleague or so I thought, but it was from my little sister.

‘Wash me more thoroughly. I let it slide this time with you just washing my thighs instead but I won’t forgive you next time if you leave some corners untouched.’

Eh? She says every corner… There’s only ‘that’ part left.

What kind of education did you give her, Mari-mama? You were right about the use of money, though I’m pretty sure everything besides that is wrong!
