My Little Sister Is the Best F*p Material - Volume 4 Chapter 12: Can I Share Something Important?

Volume 4 Chapter 12: Can I Share Something Important?

Miyu enjoys watching herself masturbate in Lolita fashion.

This absurd conclusion haunts my mind, no matter how much I try to deny it. The day Miyu’s closet secret was exposed—likely the biggest accident of her life—I realized she was enjoying watching herself in the mirror, masturbating with a vibrator while wearing Lolita clothes.

The album she desperately hid didn’t contain cute photos of her in Lolita fashion but rather images of her having sex with Haruto—or rather, being made to have sex by Haruto. She didn’t want me to know she got aroused by watching herself in those photos. Even if there were normal photoshoots in the album, she hid them all to avoid revealing her true secret. The reason she kept physical albums instead of digital images likely ties to the overly cold living room.

Why do I keep thinking about this? It’s not helping, yet I can’t stop. My curiosity about Miyu’s secrets hasn’t faded, even though it only causes her pain.

(Focus, I need to focus.)

I sat at my desk, shaking my head to clear my thoughts and return to my textbook. With college entrance exams next year, we’ve been assigned tons of homework. I’ve been catching up since finishing my part-time job yesterday, making faster progress than expected. Since Miyu started helping me, studying hasn’t felt as daunting. Especially since I started having sex with Yamamoto-san, my mind feels sharper.

Could losing my virginity have made me smarter? That’s unheard of among otaku. We believe sex drains our energy, not enhances it.

Despite my silly thoughts, something about my mindset has shifted. I’ve even considered studying on my own, which is unusual for me.

After two hours of focused study, my phone buzzed with a notification from Suzuhara: “The offline meetup is set for three days from now.” The event I’d been persistently invited to will finally happen.

The plan is to hang out at karaoke, chat, play games, have dinner, and then disband. Typical for a group of twenty-year-olds. I replied with a confirmation and headed downstairs for a break.

It was almost dinner time, and Miyu was standing in front of the fridge, looking pensive.

“What’s up?”

“I’m trying to figure out how to use up these leftover vegetables.”

Vegetables are often sold in bulk, making it hard to buy just the right amount. Plus, it’s too hot to go to the supermarket frequently, so we end up buying more than we need. Miyu was trying to plan meals to use them efficiently.

“Maybe we should make a meal plan and buy only what we need?”

“That’s a good idea. How should we do it?”

Miyu opened the fridge, staring blankly inside. Her curled hair still had a slight wave, and her languid eyes, framed by thick lashes, made her look sultry.

“Since you’re preparing for college entrance exams, I’ll take over the cooking for a while.”

“Hmm. Thanks, but I’m planning to go to East High, so I’m not really studying.”

“Seriously? East High…?”

It’s not like a high-ranked high school guarantees a good university. Still, I thought she’d aim higher.

Miyu closed the fridge without taking anything out. Was she just checking the contents?

“I hate wasting time commuting. Private schools are expensive and time-consuming.”

“But is East High really okay?”

“I decided to enroll because I admired how carefree you seemed there.”

“If you say that during the interview, you’ll be rejected immediately.”

Given her grades, they might still accept her, though.

“Even if I go to West High, I won’t need to cram. Let’s decide on the meal plan together.”

Miyu walked to the living room and picked up A4 paper from the copier. She sat at the table with a pen, looking unusually quiet.

She’s been more reserved lately. I’m not sure if this is her true self or just a phase.

After planning the meals, we moved to my room to organize the ingredients on the computer. Miyu watched me intently.

“Computers are so convenient. Maybe I should get one.”

“Go for it. They’re essential these days. Typing skills are a plus too.”

“That’s true. I also want to try gaming.”

“Really?!”

I jumped up in excitement. Calm down, me.

“If you’re serious, I can recommend a store and setup.”

“Thanks. I’ll let you know my budget and preferences later.”

“Got it.”

Miyu left the room with a flat tone. As her Onii-chan, I wish she’d show more enthusiasm, but this is typical Miyu.

I printed the meal plan and stuck it on the fridge. This should make cooking less stressful.

Miyu silently took out a frying pan and placed it on the stove. She seemed distracted, and I worried she might hurt herself.

“Do you want me to slice the eggplant for you?”

“No, I’ll do it. Thanks.”

Miyu skillfully sliced the ingredients, her movements ingrained from practice.

I sat on the sofa, enjoying the sound of her cooking. This distance felt familiar, like before we started talking. The period when I was obsessed with Miyu and considered getting a girlfriend was an anomaly.

These past few months have been intense. I’ve seen so many sides of Miyu, both cool and emotional, reminding me of her brighter childhood self.

It’s been fun. I wonder how Miyu felt about it. She’s helped me countless times, and I’ve caused her trouble. Thanks to her, I’ve become more normal and even managed to have a healthy relationship with a girl. I’ve gone from a shut-in otaku to a decent guy, all because of Miyu.

What does Miyu think of me now? Her mysterious behavior makes it hard to tell, but I feel she’s enjoyed parts of it. Like the other day when her secret was exposed—the chaos, the crying, the disgust. Despite it all, she seemed more alive then.

It’s not just about seeing her emotions. Even when she’s cool, there’s a vitality to her now that wasn’t there before.

Is it because I know her secret? Knowing she wears Lolita fashion and masturbates must make her uncomfortable. She can’t fully enjoy her hobby with me around.

Maybe I should tell her when I’ll be out. That way, she can enjoy her hobby without worrying. I’ll always call if I come home early.

I grabbed a pen and wrote my schedule on the calendar: mainly part-time work and the offline meetup. It’s a lonely schedule. Last year, I just played games all day. Since this is my last summer vacation in high school, maybe I should go out more.

Suzuhara and Takanami are probably free. Suzuhara’s been active lately, so he’d likely join me. Or maybe Yamamoto-san? She’d probably agree, but it’d be awkward. We get along at school, and she’d likely be fine as friends, but after choosing Miyu, I can’t ask her out alone. A group outing would be even more awkward.

Maybe I could invite Miyu on a date? She’s usually home in the latter half of summer vacation, so our schedules should align. Starting with a meal would be safe. But is it fair to drag her out when I’m the one who wants to leave the house?

“What’s that?”

I jumped as Miyu suddenly appeared behind me, grabbing my waist and pressing against me.

“Uh… I thought writing down my schedule would help you plan your time.”

The calendar showed my approximate outing times. If I stick to this, Miyu can relax.

“Hmm.”

Miyu studied the calendar from beside me, then gave me a displeased look.

“So, you’re telling me to masturbate alone during these times?”

Her words caught me off guard.

“N-No! That’s not what I meant! Well, it kind of is, but…”

I hadn’t thought it through. Of course, that’s how she’d interpret it.

“Like on these workdays…”

Miyu pressed the calendar with slightly bent fingers, then slipped her hand into my shirt, rubbing my stomach.

“So, while you’re working, you’ll imagine me at home doing naughty things?”

“Th-That’s… not…”

Miyu’s hobby is admiring Lolita fashion and watching herself have sex in it. She’s kept it a secret because she doesn’t want me to think she’s doing that when I’m not home. That’s why she kept me away from Haruto.

“Hmph.”

Miyu stepped back, moving to the sofa. I followed, sitting at a comfortable distance.

“Sorry, I didn’t mean to pressure you. I just wanted to support your hobby. I’d love to help if I can.”

I struggled to find the right words. I wanted to help, but I didn’t want to push her.

Then, I heard a soft laugh.

“I’m joking.”

I looked at Miyu, surprised. Her expression was warm, unlike her usual cool demeanor.

“I know you were trying to help because I’ve been quiet. Thanks, Onii-chan.”

Miyu closed the distance between us, snuggling against my side.

“Thank you, Onii-chan.”

Her words made me smile. Her tone was so genuine, unlike her usual self. Maybe I’ve cheered her up.

“Does knowing your secret bother you? I want to support you, but I don’t want to make things harder.”

If I could, I’d erase this memory for her. Since I can’t, maybe I could help with her hobby. Miyu smiled teasingly at my suggestion.

“Is it because you just want to watch?”

That caught me off guard.

“Well, I definitely want to watch.”

Miyu loves seeing herself in cute outfits, and given her past behavior, she probably enjoys being seen too. There must be a compromise that allows her to continue her hobby. After all, when she was little, she’d always show off her new outfits to me. I’d just stare in awe, unable to say anything.

“Hey, Onii-chan…”

Miyu clung to my arm. The living room was spacious, and her closeness made me nervous. What’s she up to now?

“The food’s getting cold.”

“Huh? Oh, right! Let’s eat quickly!”

I rushed to move the dishes from the sink to the table. Even though Miyu had just finished cooking, I should’ve known better. Tonight’s stir-fry didn’t take long.

“Let’s eat.”

Sitting across from Miyu at the table felt normal, like it always had since we were born.

How long will it stay this way? Since I learned her secret, things will inevitably change. But I don’t want to lose these moments together.

“About what we talked about earlier…”

I believe I have the right to try.

“Is there a way I won’t be in your way?”

I wanted to settle things after the incident two days ago.

“There’s something I need to tell you first.”

Miyu stopped eating and looked at me.

“Human thoughts don’t always align with emotions.”

It’s been a while since Miyu gave one of her philosophical lectures. Like wanting to eat but not wanting to because you’re dieting.

Miyu rejected me impulsively when she was seen in her Lolita outfit, but her feelings weren’t entirely negative. Hmm, I’m still confused.

“So… you didn’t think I was in the way?”

I’m not sure I understand, but that seems to be what she’s saying. Miyu nodded.

“I never thought you were in the way. But when you ask if I’m okay with being seen, it’s not that simple.”

That makes sense with her contradictory behavior. Or does it? I’m still not sure.

“So, I’m genuinely happy you accept my hobby. Thank you, I’ve been thinking that a lot. But the embarrassment and wanting to keep it secret haven’t gone away.”

Hmm, I see.

“It still feels like I’m in the way…”

If she’s embarrassed and wants to keep it secret, then me not being around would solve the problem. She could enjoy her hobby freely.

“Don’t worry about it. You’ll understand eventually.”

Miyu said gently, then continued eating. Maybe it’s something I can’t understand yet. At least she’s not upset, which is good.

“As long as I’m not ruining your mood, I’m fine.”

“My mood’s fine. Sorry for worrying you.”

The atmosphere at the table was peaceful. Maybe her low mood was just my imagination.

The silence between us wasn’t uncomfortable. It’s a big improvement from before summer. I’ve grown a lot, even if I started from a low point.

“I’ll wash the dishes. You can plan the shopping schedule based on the meal plan. I’ve written my schedule on the calendar.”

“Got it. Thanks for the dishes.”

After eating, I took the dishes to the sink and started washing them. The sound of water was soothing, and I found myself lost in thought. No wonder dishwashing is said to relieve stress.

I’ve become more proactive and confident in my opinions. Before, I’d overthink and worry about being rejected or misunderstood. Now, that fear is gone. Miyu’s improved my appearance, and Yamamoto-san boosted my confidence. I can’t do much yet, but I want to repay them through small daily actions.

As I washed the dishes, I felt something soft press against my back.

“Miyu? What are you doing?”

She was closer than before, her body pressed against mine.

“Just a little check.”

Miyu sounded content, her breath warm against my back. I had no idea what she was checking, but it felt so good I didn’t question it.

Even after I finished the dishes, Miyu stayed close. Was she smelling me? Should I stay still?

“Onii-chan…”

Miyu pulled away from my back, tightening her arms around my waist.

“Why didn’t you date Yamamoto-san?”

That was unexpected. We had a good connection, and she seemed to acknowledge me as a man. Yet, I never considered dating her.

How should I answer? Simply put, it’s because I chose Miyu. But she’s my sister, and I’m not ready to say I love her as a woman. I’ve never thought about it seriously, but choosing Miyu means that, right?

“Honestly, I’m not sure. I liked Yamamoto-san as a person, but I never thought about dating her. I just didn’t consider it.”

Even I was puzzled. Why didn’t I pursue her after such an intimate week?

“You’re not very decisive, are you?”

Miyu muttered against my back. Don’t say that in this situation.

“Sorry for not having dating experience.”

My only “relationship” was with Sachiko, whom Miyu set me up with. Before that, I was tricked into thinking a girl liked me, only to be hurt. My youth was far from romantic.

“Hmph. In a game, you’d never get to have sex again with that answer.”

“Huh? What?”

“Pay attention to me, Onii-chan.”

What does she mean?

“Don’t you find this situation strange?”

Miyu tightened her grip around my waist.

I’m extremely confused. I have no idea what’s going on.

“So… what is it?”

If this were a game… then it must mean my affection level has reached a certain point. I need to tell Miyu how I feel.

“I didn’t date Yamamoto-san because I chose you. In other words, I like you, Miyu.”

Saying it out loud feels strange.

“Is that so?”

What kind of response is that? I mustered all my courage to say that.

“What’s the correct answer?”

“There isn’t one. But it made me a little happy, so thanks.”

“You’re welcome.”

She’s impossible.

“Did you get the answer you wanted?”

“Not exactly, but it’s over, so don’t worry about it.”

With that, Miyu let go and headed upstairs.

It’s been a while since I’ve felt so confused. I thought knowing her secret would help me understand her, but I’m still clueless about her thoughts.

I placed the dishes in the drying rack and decided to take a bath. As I left the kitchen, I noticed a star mark on the calendar, with Miyu’s name beside it. It must be a shopping day.

The neatly drawn star, with its rounded edges and tilt, felt so like Miyu.

Ah, I remember now. After the week with Yamamoto-san and the closet incident, I’d buried these feelings. But they’re still here—my love for Miyu.

“That’s why I chose you…”

I muttered to myself, feeling lighthearted as I drew a bath. I’m completely relaxed. Miyu doesn’t think I’m in the way, and her mood’s fine. Given how affectionate she was in the kitchen, maybe she’s starting to like me as a man.

I hope she’ll take a bath with me again. If I’d asked today, maybe she would have. I want to see her breasts again. And maybe… do something more with those bountiful fruits.

Wait, stop it! My lower half is reacting. I’ve been so worried about Miyu I forgot to relieve myself. I need to take care of this before I become a terrible Onii-chan again. I’m almost there.

After my bath, I called out to Miyu, and she went in next. I have a few minutes alone. I’ll finish before she comes back. It’s been three days, and I’m at my limit.

I started before putting on my pajamas. It’s been so long since I’ve done this alone. My erection is throbbing. I’ve been so spoiled with erotic experiences.

How long has it been since I last did this alone? Months? I’ve been living a luxurious erotic life.

The last time I was teased, I released all the built-up semen into Yukari. This will be the first time I’ve ejaculated so much alone. I wonder if Miyu will drink it all, even if it’s thick and messy. What expression will she make?

(What am I thinking…?)

Just a few days ago, I decided to become a better Onii-chan. But now, just because my libido’s built up, I’m about to throw that away? As a man, I can’t accept that. I have to keep my promises, at least the ones I make to myself.

I still need to repay Miyu. The immediate issue is how to let her continue her hobby. When it comes to Miyu, nothing else matters. My mission is to create an environment where she can enjoy her Lolita fashion and masturbate freely.

It sounds like Miyu’s the pervert here, but everyone has their own preferences, and I have no right to judge. After all, I’m the one who’s done unforgivable things—having my sister set me up with a girlfriend, graduating from virginity, and even raping her friend. I’m no saint, so I can’t call Miyu a pervert, especially since she’s smart, kind, and incredibly cute.

But still, from an outsider’s perspective, it looks like I’m enabling my sister’s “perverted” behavior. Miyu enjoys wearing Lolita fashion and watching herself masturbate in it. I’m trying to help her with that, while taking care of my own needs…

Wait, why am I overthinking this? It’s not like I’m doing anything normal either. But why does Miyu’s uniqueness stand out so much? Is it the contrast?

Miyu’s the one who started all this—drinking my semen, making me rape her friend, and everything in the bath. So, if anything, she’s been abnormal from the start. Now that I’m becoming more “normal,” her quirks stand out even more.

“Ah, I see! That’s it!”

I blurted out loud. I shouldn’t have become so “normal.” If I stop wanting to have sex with Miyu, it’ll make her the only “pervert” in our relationship. That’s unfair and the opposite of repaying her.

That’s why Miyu’s been acting down lately. With me becoming more normal and less intimate, she must be confused by the change.

So, that’s it. I can’t just sit here and masturbate. More than anything, I want to have sex with Miyu.

But after becoming so platonic, will Miyu be confused if I suddenly ask for sex? She’d probably sense my sympathy, even though I genuinely want it. And she’d likely realize I’m using her “perversion” as an excuse.

There must be a way. Think, I can do this. My mind’s been sharp lately. If I can’t figure this out, what’s the point of having a brain?

“Onii-chan? Did you just shout?”

Miyu’s voice came from behind the door. She must be out of the bath.

“Oh, uh, I almost dropped my phone. Sorry for the noise.”

Miyu’s voice is so erotic, even through the door. I’ve ejaculated to her commands so many times. No wonder my body can’t reach climax without her.

“Alright, here goes.”

If Miyu brushes her teeth, she won’t drink my semen. I can’t wait until morning with this erection. Miyu should be relaxing in her room after her bath, the perfect time to catch her.

I’ve already planned my approach. I know how to lead Miyu to have sex with me. My goal is clear: I want Miyu to give me a blowjob, my long-standing desire.

“Miyu, can I talk to you?”

I knocked on her door, waiting for her response.

“What is it?”

Miyu opened the door just enough for her body to fit through, welcoming me in her pajamas. Her post-bath hair was slightly curly, making her look a bit different. She wore the same pajamas as when we first slept together, the heavy fabric creating a nice cleavage.

“I’ve been thinking, and I realized I haven’t received enough of an apology yet.”

Two days ago, Miyu knocked me out with a punch, and while she promised to make amends, she refused to let me go down on her and even told me to forget about the album. Her apology felt insincere.

Miyu’s face turned slightly red as she understood what I meant.

Then, she closed the door without a word.

“Uh, Miyu?”

Her reaction was unexpected, but she wouldn’t ignore me completely. Sure enough, after a moment, she opened the door again.

She looked extremely reluctant.

And then, she glared at my bulging crotch.

I felt relieved by her reaction.

“Come in.”

Miyu grumpily invited me into her room. She seemed to feel obligated to apologize.

She let me sit on her bed since she’d just taken a bath. Miyu sat in front of me, cross-legged.

“This feels like it’s undoing the progress we’ve made in the past two hours.”

Miyu was right. In just one moment, I’d shattered the image of a “normal Onii-chan” she’d built over the past three days.

“I had my reasons, but after three days, I can’t hold back.”

Being affectionate with Miyu was nice, but our relationship isn’t supposed to be like that. I need to have sex with her.

“I can guess what you’re thinking. You want me to extract your semen and drink it as an apology, right?”

Miyu’s tone was businesslike, a stark contrast to before.

“Yeah. It’s been almost ten days since we last did it, and I’m ready.”

I spent a week with Yamamoto-san, but I still crave Miyu’s touch. Sex with Miyu is special—no one else compares.

“You should’ve kept having sex with Yamamoto-san.”

Miyu grumbled as she reached for my pants. She helped me take them off, revealing my erect penis.

“It’s been a while, and it still looks disgusting.”

Miyu poked my penis, her finger tracing the tip. She looked disgusted by the pre-cum.

“It smells so strong, even though you just took a bath…”

Despite the bath, my penis smelled strongly of arousal, as if I’d just ejaculated.

“Sorry, I didn’t expect this.”

“Ugh, whatever.”

Miyu gripped my penis lightly, moving it up and down without rhythm. She’s become more comfortable touching it. Just her warm touch was enough to make me want to climax.

“I’ve been meaning to ask…”

Miyu kept her eyes down, her hands not stopping.

“Are you expecting… a blowjob as an apology?”

I hadn’t considered anything else.

“Didn’t I say blowjobs were okay?”

“I’m only doing this because I said I would, but now that my secret’s out, I don’t owe you a blowjob.”

Fair point. With her secret exposed, she doesn’t need to go that far.

But I’ve always wanted a blowjob from her. I need her to do it, to fill her mouth with my three days’ worth of semen.

“If you can’t, it’s fine. I was partly to blame for getting hit. It’s up to you whether you apologize.”

I said this, even though I desperately wanted her to do it. Now, it’s up to Miyu’s sense of responsibility.

“Fine, I’ll do it.”

Miyu took a deep breath, moving her face closer to my penis. Her breath tickled the sensitive tip, making me want to climax instantly.

Miyu stuck out her tongue, hesitating. She held my penis carefully, staring at the pre-cum with a frown.

Her lips, hesitant like a child eating vegetables, touched my glans, sending shivers through my body.

“Ugh… ah… it feels so good…”

Miyu’s mouth, which she’d resisted so much, was now wrapped around my penis. She started with kisses, then took more of me in, stopping just at the base.

“Mmm… nchu… nmm…”

Her tongue swirled around the tip, sending waves of pleasure through me. The sight of my penis disappearing into her mouth was incredibly arousing.

“Nmm… chubu… juru… chu… haa… ugh…”

But just as I was about to climax, Miyu pulled away, leaving me frustrated. She wasn’t tired or disgusted, just embarrassed.

“Is it hard to keep going?”

“Honestly, I’m too turned on. Onii-chan, your blowjob is making me so excited.”

Miyu pressed her thighs together, clearly wet. Her pajamas were probably soaked.

“Can you keep going until I finish?”

She nodded, determined, and took me back into her mouth.

“Ngu… chubu… nmm… nnn… chu… juru…”

“Ahh… Miyu… so good…”

Her inexperienced movements only added to the excitement. Despite her lack of practice, she knew the basics, and her effort to make me climax was adorable.

Just as I was about to explode, she pulled away again, her face flushed.

“Miyu? What’s wrong?”

She didn’t answer, just breathed heavily, her body tense.

After a moment, she tugged at my shirt, signaling she wanted to talk. I leaned in, and she whispered:

“I’m about to climax.”

“Just from giving me a blowjob? That’s incredible.”

She nodded slightly, too embarrassed to speak.

If she climaxed while I was inside her mouth, she might not be able to swallow all my semen. I wanted to see her climax, but not at the risk of making a mess.

“What would make it easier for you? I can finish with just your tongue if needed.”

The easiest option would be to stop, but I couldn’t do that. It would feel like rejecting her.

“I’ll keep going with my mouth, but can I use my hand too?”

“Of course. Thank you.”

“You’re welcome. Next time, I’ll try just my mouth.”

She took me back into her mouth, using her hand to stimulate the base. Her tongue worked the tip, but she couldn’t move her mouth much without triggering her own arousal.

Still, she was determined to swallow my semen. That was all that mattered. Her dedication to drinking my cum, even while struggling with her own pleasure, was incredibly arousing.

“Ahh… I’m close…! Swallow it all…!”

My emotions peaked, and I began to climax. My semen surged into her mouth.

“Nmm… nnn… amu, juru… chu… haa… nmm… ihiyo, rahite… onii-chan no seieki, ippai nomasete…”

“Ugh… guh, ahh…! I… I’m cumming, Miyu…! Uuu… ahhh… I’m cumming…!!”

*Dobyurururu, byuku, byuku byuku, doku, doku, dokun, dopu dopu, dobyururu, dopun*—!!

My semen shot into her mouth, stretching her lips with each pulse. Watching her swallow it all was incredibly exciting, and even as I climaxed, my arousal grew.

I ejaculated again just seconds after the first.

“Nnn… nnn…!”

Miyu looked like she wanted to stop but managed to swallow every drop, her expression blissful. Her throat worked, and I felt my arousal building again.

“Miyu… sorry… I’m… still… cumming…!”

I kept ejaculating until every drop was gone.

“Ugh… uguu… upu…”

Miyu’s eyes teared up, but she kept going. I have no idea how long I climaxed.

“Gah, gefu! Keho, haa, haa… fuu…”

Miyu held her throat, looking distressed. The volume and thickness of my semen must have been overwhelming.

“Too much at once. How much do you want me to drink?”

Miyu stood up, trying to hide her embarrassment, and walked quickly to the door.

“I’ll get some tea.”

“Okay. Take your time. Thanks.”

“You’re welcome.”

She left with a stern expression. I can’t blame her for being upset.

But I finally got a blowjob from Miyu. It was even better than I imagined.

“Hmm… I wonder…”

Was it true she was close to climaxing? She admitted it was arousing, so it’s possible.

If so, she’s still aroused. Given how she acted in bed, she must want pleasure too. I can’t stop now. I need to make her feel good, even if she doesn’t ask.

I followed her downstairs. Even if I’m wrong, I can’t let fear stop me from making her happy.

I’ll accept any punishment. Miyu’s the dominant one, and she’d never let me do something she truly hates.

In the living room, Miyu was in the kitchen, drinking tea. She raised her glass when she saw me, but I shook my head and approached her.

“Thanks again.”

“It’s my duty as your sister.”

Miyu leaned against the kitchen counter, subtly criticizing my libido. Her sharp words, now, felt endearing.

“I’m always happy that you drink it all without spilling.”

I moved behind her, gently wrapping my arms around her waist.

“It’s gotten even worse, hasn’t it? I hope it doesn’t get any thicker than this.”

Miyu, despite her worries, placed her hand over mine on her waist. She didn’t resist my embrace. I hugged her lightly, and she didn’t pull away.

“It might get thicker and more voluminous.”

“Ugh… that’s really troublesome…”

Miyu rubbed my hand with her fingers, almost playfully.

“Is it because drinking thicker semen turns you on?”

After the blowjob, I was certain. Miyu had always gotten aroused whenever she drank my semen. With each ejaculation, the volume increased, and she began to associate drinking it with pleasure. Even though she tried to distance herself from me, she couldn’t handle the loneliness when I got closer to Yamamoto-san.

There was something I’d always wondered about. Whenever we had sex, Miyu was always incredibly wet. I thought it was just her being naturally wet, but now I realized it was because she was turned on by me. Her body wanted me, even if she tried to hide it.

“Stupid.”

Miyu muttered, not pulling away. She even held my wrist, keeping me close.

“Miyu, you’ve become more mature.”

I moved my hands down, toward her thighs. Her lips, voice, and even her height—she was growing into a woman.

“Nnn… Onii-chan… what are you doing…”

As I began to touch her, Miyu squirmed, but she didn’t resist strongly. She used her embarrassment as an excuse to hide her desire.

“I don’t want to just watch anymore.”

I slipped my hand into her shorts, rubbing her inner thigh and the area between her legs.

“Stop… there… it’s… no good…”

Miyu resisted weakly, her voice breathy. She didn’t seem angry, just embarrassed.

“I can’t hold back anymore.”

I slid my hand into her panties, feeling her wetness. Her lips were swollen, and she was incredibly aroused.

“Onii-chan… there… no…”

Miyu squirmed, but I held her firmly. I gently pressed her clit through her hood, watching her reaction.

“Fwa… ugh… Onii-chan… it’s embarrassing…”

Miyu’s hips twitched, trying to rub against my hand. I increased the pressure slightly, and her reaction intensified.

“Don’t… tease me… too much…”

Miyu begged, her voice shaky. I decided to be bolder, pressing her clit directly.

“Ngu… nnn…!! Haa… uguu… nnn… ahh…!!”

Miyu’s body shook violently, and she collapsed onto the floor. I knelt beside her, holding her tightly.

“Sorry, did it hurt?”

“It didn’t hurt… just… embarrassing…”

Miyu didn’t pull away from my touch. She asked me to be gentler, and I agreed, resuming my stimulation.

“Is it okay to touch directly?”

“Ugh… yeah… just a little… it’s okay…”

I pressed her clit gently, and her reaction was intense.

“Ngu… nnn…!! Haa… uguu… nnn… ahh…!!”

Miyu’s body shook, her breath coming in gasps. She rubbed against my hand, her desire overwhelming.

“Does it feel good? Miyu… you’re so sexy.”

“Haa… fuu… it feels good… nnn… ahh…! Uguu… nnn… ahh…! It’s… embarrassing… haa… fuu… nnn…!!”

Miyu’s voice was filled with pleasure, her body trembling. I held her tightly as she climaxed.

“Ahh… uguu… I’m… cumming…! Fuu… ahh… it’s… so embarrassing… ahh… ahh…!!”

Her voice rose, and her body shook violently. I held her close, feeling her climax.

After her orgasm, Miyu’s body continued to tremble. I watched, captivated by her reaction.

“Uuu…”

As Miyu calmed down, I realized my hand was covered in her arousal. I thought about licking it off, but Miyu handed me a kitchen towel.

“Wipe it off.”

“Oh, okay.”

“Girls don’t like licking their own fluids.”

I didn’t know that. I’ll remember to wipe it off from now on.

“Whatever.”

Miyu tried to stand but collapsed into my arms. She looked exhausted, her face flushed.

I helped her to the sofa, where she pushed me down and lay on top of me.

“Ugh… fuu. Are you okay, Miyu?”

Miyu buried her face in my stomach, then suddenly started kicking her legs.

“What’s wrong?”

She did it a few more times before stopping, looking incredibly embarrassed.

“Uuu… it’s so embarrassing… ahhhh!!”

Miyu kicked her legs again, hitting my stomach with her head. Girls really are weak when they’re on the receiving end.

“Ugh… you’re so heavy…”

Miyu’s breasts acted as a cushion, making her headbutts less effective.

After a few attempts, she gave up, her energy spent. I held her, unsure what to do. She placed my hand on her head, and I started stroking her hair.

Soon, she fell asleep, her breathing steady. I kept stroking her hair, unable to sleep myself.

About an hour later, Miyu woke up.

“Good morning.”

It was late, but it was the only greeting I could think of.

“Mmm… good morning…”

Miyu was still groggy. I tried to sit her up, but she clung to me, refusing to let go.

“Miyu, this position is getting uncomfortable.”

She finally sat up, looking exhausted.

She sat beside me on the sofa, resting her head on my shoulder.

“Are you okay? Do you need water?”

“Later. Just let me stay like this for a bit.”

She leaned against me, her anger seemingly gone. She always opens up after being angry.

“I’ll tell you something, Onii-chan.”

“What is it?”

“Something you’ve been wondering about.”

The biggest question was why she started drinking my semen. And why she suddenly allowed physical contact after the toilet incident.

“There’s a lot…”

“Including all that.”

Miyu held my hand, looking straight at me.

“I have an important story to tell you. Will you listen?”

It was a story about our past—how we started having these moments, and what happened before that.

It was a story about why I sought her out, and why she accepted me. A story about the roots of our relationship.
