A Man Who Lost Confidence, to a Gentle Chastity-Reversed World

Chapter 72: Mom Reflects and Paves the Way

“…I-I know it’s weird to say, but I really want you to hear me out, s-so…”

When asking something, my habit of long preambles hasn’t changed from my old world. To calm myself, I take a deep breath and meet Mom’s eyes.

Normally, even with Mom, her beauty makes my heart race, but that’s not the issue now.

“I-I talked to Yukari-san earlier, but… a-about Yuki… I-I definitely want to cherish her as my sister…”

My gaze nearly drops to the floor, but I hold it, catching Mom’s eyes. She looks at me with her natural smile.

“…B-But I’ve always thought… Yuki’s a cute girl… I-I know I might not be supposed to feel that about my sister…”

Mom doesn’t interrupt, even encouraging me. So, like with Yukari-san, I ask her.

“…I-If Yuki and I… h-had that kind of relationship… w-what would you think, Mom? Y-Yuki’s so open with me, and I… might look at her that way…”

Might—actually, I already look at her erotically often. I needed to know how Mom sees that.

Objectively, a parent allowing their son and daughter to have sex is bizarre. Even in this world, I don’t know if it’s normal.

But since Yuki, whom Mom birthed, could be “tainted” by me, I feel I must tell her, even vaguely.

“…Really, Shun-kun… you’ve changed. A few months ago, I couldn’t imagine you saying this.”

Her soft, affirming words come back. After a sigh, Mom responds to my selfishness.

“It’s the same as with Yukari-chan. If you and Yuki feel that way about each other, you should get close as you like… I wouldn’t stop it.”

I didn’t expect Mom to harshly reject me, but I thought she might gently say no.

Yet, she dismisses even that, looking at me warmly.

“Come on, you’re family, but you’re young and close in age… For women, it’s natural to think about it. Yukari-chan was like that, right?”

I don’t see Yukari-san’s expression beside me, but her silence suggests she agrees. I’m still not used to a weak guy like me inspiring such feelings.

“Yuki probably wanted to be close to you, but… I think you had some fear of us. I always wanted to fix that.”

“But… now, you seem to accept everyone’s feelings. You shouldn’t push yourself, but if those feelings lead somewhere good, isn’t that ideal?”

Ideal—it’s ticklish, even an overestimation. I’m just leaning on women’s kindness, craving erotic things.

“A family where everyone loves each other, in a gentle atmosphere… I think that’s ideal, even in society. It’s hard, but… with you now, Shun-kun, you might make it happen.”

Mom laughs, “Fufu,” looking at me and Yukari-san.

“Of course, if you two fought over Shun-kun, that’d be a problem… but I don’t think you would. Yuki sees Yukari-chan like a real sister.”

Yuki does call her Yukari-neechan and gets along well; I can’t imagine Yukari-san being cold to her. Fighting over me is unthinkable.

“…I’m not sure if I’m saying this right, but… if you can be close with both within your limits, creating a calm atmosphere, everyone could be happy… So, I’d never stop it.”

“Me, Yukari-chan, Asagi-chan, Maki-chan… none of us would reject what you want. If we did, Yukari-chan would’ve said something by now.”

After saying this, Mom pauses, glancing at the wall calendar.

“…And the timing’s good. Yuki’s birthday is two weeks from Friday… How about going out together?”

“Yuki’s always said she wants to go out with you. This weekend’s a school test, so… maybe as a reward?”

I nod, led along. Belatedly, I realize I don’t know Yuki’s, Mom’s, Yukari-san’s, Asagi-san’s, or Maki-san’s birthdays.

As a lover, I should know and give gifts. If their birthdays passed, I hate my carelessness.

Tomorrow, I need to tell Asagi-san and Maki-san directly—gratitude for Yukari-san and about Yuki. I’m scared they’ll be disappointed in a guy who doesn’t know birthdays, but I have to face it.

Declaring I’m in a three-way relationship, soon four, is something I never imagined. Even in this reversed world, I have no confidence I’m worthy.

“…But Yuki better not get bad grades. If she can’t focus, it won’t be a reward… Fufu.”

Mom stands slowly, saying, “Yukari-chan, rest when you get home,” heading to the entrance.

Going out as a reward feels odd, but if Yuki enjoys time with me, nothing could make me happier.

I can’t help wondering if I’m enough for her, though.

With Mom, I see Yukari-san off at the entrance. I thank her repeatedly for thinking about Yuki with me.

Mom says, “Yukari-chan, you can rest tomorrow too,” perhaps thinking she’s tired from being with me.

But Yukari-san bows, “N-No…! I-I’m fine…! Th-Thank you…!” and leaves humbly.

“…I wonder how Yukari-chan will be tomorrow morning… I’m a bit excited,” Mom says, smiling slightly.

“U-Um, Mom… thanks. I’m leaving everything to you…”

I got a date with Yukari-san set up and declared I’d pursue Yuki. Yet Mom thinks of us.

“It’s fine. You’re so lively, getting close to so many people… As a mother, I’m thrilled. So, thank you, Shun-kun.”

Her smile feels all-seeing, wrapping me in warmth.

Eating Mom’s lunch, I learn more. Yuki has a school test Friday, so she’s at tutoring. It affects her grades, so it’s important.

Yuki aims for my high school, a goal since last year, stronger since April when I stopped rejecting her touch, Mom says.

“Lately, she studies a lot when not with you. She might want your praise.”

I’ve always been bad at praising, feeling it’s creepy coming from me.

But if Mom says so, could I say, “Good job,” and would Yuki smile, not minding?

Finishing lunch, I return to my room, thanks to Mom’s, “Rest if you’re tired.”

At my desk, studying with half focus, I notice it’s 3 p.m.—Yuki’s return time.

Mom said going out is a reward—what will Yuki think? Will she come to my room? I tense up.

I’m hyper-aware. Living with Yuki, her soft body occasionally pressed against me, is already beyond my old world’s norms.

When a woman smiles or touches me, my head fills with her cuteness or sexiness. I’m scared I’ll get forceful with Asagi-san, Maki-san, Yukari-san, or Yuki.

As I think this, footsteps patter, and my door is knocked. Startled, I freeze, then rush to open it.

“…I-I’m home, Shun-nii… U-Um, is now okay…?”

Yuki, just back, looks up at me. Even standing straight, she’s shorter, making me more nervous than usual.

“U-Um… I-I heard from Mom… A-After this week’s test… u-um…”

I sit in my chair, Yuki on my bed. She jumps to the point.

I worry she might not want to go out, but I wait for her words.

“Y-You’ll… go on a date with me…? I-Is that really okay…?”

Date—a sweet word, but I’m not the kind of guy it suits.

Yet, Yuki’s earnest question lacks any teasing, so I can only answer honestly.

“…I-If you think that way, Yuki… I-I’m happy… A-And you’ve always said you want to go out, but I-I couldn’t invite you well…”

Even now, without Mom’s help, I couldn’t have suggested a date.

Yuki’s bright and lively; going out with gloomy me might not be fun. That fear sticks in my heart.

“…I’m so happy…!”

Suddenly, Yuki, from the bed, lightly pounces on me. My chair wobbles, supporting us both.

Her soft scent and slight chest press against me. Like a cuddling cat, she rubs against me.

“Y-Yuki…” I stammer, flustered. She pulls back slightly, but her bare legs stay on my thighs, their softness pressing in.

“…I’m really happy… Y-You’re paying attention to me… Thank you, Shun-nii…”

Her joyful gaze, pure and beautiful, shakes my heart undeniably.

“I-I really want to go to your high school… I’ve always thought that. B-But if I get a reward like this from you… I-I’ll work even harder…”

Wriggling, she says this. If her feelings were a lie, I’d trust nothing, but she’s so sincere.

“T-To say that… I-If it helps you work hard, I-I’d go out with you… any time…”

I might be getting carried away, but I want to meet her hopes. She responds, “R-Really…?” her voice full of expectation.

“…I-It’s so exciting to hear that… B-But I have to study hard too… I-I might end up relying on you too much, Shun-nii…”

Toward the end, she looks away, seeming conflicted. That conflict only makes my heart race, and if she kept relying on me, I’d probably melt completely.

“Th-Then… w-when you get good test scores or finish a big mock exam… m-maybe I could… take you on a date… I-It’s extravagant, but…”

Yuki’s suggestion isn’t extravagant at all; I think I’m already dominated by the desire to spend sweet time with her.

“…Y-Yeah, of course… I-I’m the one who wants to ask that…”

Hearing my answer, Yuki beams and gives my cheek a soft touch. This act makes my heart pound repeatedly.

“…Hehe, Shun-nii… I-I’ll study super hard this week… s-so I can go on a date with you next weekend, all confidently!”

Jumping off my lap, she kneels on the floor. Honestly, any more closeness, and I might’ve gotten hard again, so maybe this saved me.

Looking at me, she tilts her head cutely, her gesture completely natural.

“But… don’t hold back from spending time with other girls just for me, okay? I feel like you might think it’s bad to hang out while I’m studying.”

As I start to say, “Th-That’s…,” she makes a small X with her fingers.

“…No way, okay? You’re an amazing, cool guy who can make Asagi-san, Maki-san, and Yukari-neechan so happy…”

“And… I think you’re better off with someone. To avoid overthinking or feeling lonely.”

She’s absolutely right. My weakness is stewing in anxieties alone, feeling like the world’s most miserable person. The women around me see through that.

“So, talk to lots of girls… and tell me about it later. If you’re alone and sad… I-I’d feel sad too, you know?”

Spending time with other girls to keep Yuki from feeling sad—it’s too convenient, almost absurd unless Yuki says it.

But since she does, I accept it. Nodding, I see her smile contentedly and stand quietly.

“And… you seem to get excited even with me… l-like you really love erotic stuff… I-I don’t want you to hold back on that… It might be harassment, but…”

I’m the one who should worry about harassment; Yuki doesn’t need to. In this world, I’m the one who can’t restrain my lust, the one who should be criticized.

Blushing, Yuki speeds up, changing the topic.

“S-So, um… I’m thinking of going to school early to study until Friday. B-But that’d mean you’d go alone, which kinda contradicts what I said.”

“So, why don’t you ask Asagi-san or Maki-san to go with you until Friday? You’ve been going with me lately, so… I bet they’d love to, too.”

I agree with an “U-Uh-huh” to her bright request. But inviting them means contacting them now, a daunting task.

Even with lovers I’ve had sex with multiple times, I worry sudden invitations might annoy them. I still can’t grasp how lovers feel in this world.

“Okay, I gotta study! Thanks, Shun-nii!” she says, leaving with a bright vibe, her soft scent and touch lingering.

In the end, I sent a safe message to both, “Want to go to school together tomorrow?” and ended up going with Maki-san. Asagi-san had morning basketball practice.

“Sorry… I really wanted to go with you…” she apologized, but it was a last-minute invite, and her club takes priority over me.

So, the next morning, I walk to school with Maki-san for the first time in a while. Usually with Yuki, it feels fresh, though I wonder if it’s okay.

Waking up, I heard Yuki leave, so breakfast was rare—just me, Mom, and Yukari-san. Yukari-san avoided eye contact but made delicious food as always.

Seen off by them, I head to the school path. At the intersection, my girlfriend waves slightly at me.

“…I see… it’s that time for the achievement test, huh…”

Walking slowly with Maki-san, I mention Yuki’s situation, and she recalls last year.

“But Yuki-chan will definitely work hard if it means going out with you. If you said that to me… I-I’d study like my life depended on it…”

I told them yesterday via message about my date with Yuki next Friday. Neither got mad, accepting it. Honestly, sending that message made my heart race.

But I want to discuss my resolve to be physical with Yuki in person, during lunch or after school.

It’s a ten-minute walk with people around, so it’s hard to talk about. I don’t even have the courage to hold hands.

Nearing school, I ask Maki-san something bothering me—she kept glancing at my upper body.

“U-Um, Maki-san… I-Is something wrong with my uniform…?”

She squeaks, “Hya, hyai!” in a cute way, then shrinks, explaining apologetically.

“…S-Sorry… I-I didn’t expect you to wear summer clothes… I-It’s… not eye candy, but… m-makes my heart race…”

I realize Mom was right when I left.

From late May, summer uniforms are allowed, but Mom said boys usually keep wearing blazers. Wearing just a shirt, like me, is rare.

With today’s heat forecast, I skipped the blazer, and Mom seemed momentarily surprised.

But she said, “You don’t seem to mind girls’ stares… Just be careful, okay?” and let me go like this.

“G-Guys don’t usually dress so lightly… You’re special, Sato-kun… I-I thought that… Sorry…”

I don’t see the appeal in my outfit, but Maki-san’s summer uniform matters more.

Same ribbon, no blazer, just a thin blouse—her huge breasts stand out more. Her white bra shows clearly from the front, drawing my eyes.

A front-view bra is rare; I never saw it in my old world. Yet this erotic girl exposes it so openly.

Her G-cup breasts could make me hard, so I try to focus on her face, only to reconfirm her cuteness.

I end up talking to her, eyes wandering, suppressing arousal to reach school.

As Yuki said, I’m aware I can’t restrain my lust, heading to class with her.

The classroom is as expected. Most boys wear blazers; half the girls, like Maki-san, wear blouses.

Blouse-wearing girls show off their chest sizes and shapes unreservedly. For someone who loves bra flashes and cleavage, their openness leaves me nowhere to look.

Scared I’ll get called out for staring, I sit nervously. Soon, Asagi-san enters, looking slightly surprised.

“…I-I thought maybe, but… you’re too defenseless, you know?”

She whispers just to me, sitting in front. I get her intent, feeling more eyes on me than usual.

At lunch, we head to the rooftop as usual. Nervously, I prepare to tell them about yesterday.
