My Little Sister Is the Best F*p Material - Volume 5 Chapter 6: Disliking the Taste is Different from Finding it Tasteless

Volume 5 Chapter 6: Disliking the Taste is Different from Finding it Tasteless

After finishing the photoshoot in Lolita fashion, I was waiting for Miyu in my bedroom. Although I wasn’t completely energized after ejaculating twice, since Miyu had personally asked to take my manhood into her mouth, there was no way my body wouldn’t be ready. My penis, rock-hard since earlier, was eagerly awaiting the moment Miyu would take it into her mouth.

“Onii-chan, I’m coming in.”

It didn’t take as long as I thought for Miyu to arrive at my room. She seemed to have left most of her makeup on.

Miyu was dressed casually in a T-shirt, and since she rarely wears makeup in daily life, seeing her with heavy makeup made her look like a delinquent girl, which was exciting. Miyu, who seemed quite aroused from the earlier fellatio, walked steadily, but her cheeks were relaxed.

“Onii-chan, why are you already hard?”

Despite being the one who asked to take it into her mouth, Miyu looked exasperated. Since she’s the reason I’ve come to enjoy ejaculating in her mouth, she should take responsibility.

“When I think about Miyu giving me a blowjob, I can’t help it.”

“You’ve already cum twice, you know.”

“I feel like my semen is building up again.”

“Seriously, your libido makes no sense.”

Miyu sat in front of me, complaining all the while. Without hesitation, she pulled down my pants. There, my manhood stood as firm as before.

“You know, it feels like it’s gotten bigger since the first time I saw it.”

“Really? Honestly, I’m not sure about the size… but it does feel a lot heavier now.”

It’s not like it’s grown several centimeters. Compared to the average size of my peers, it’s just about average. But in terms of overall firmness and hardness, I think it’s become quite impressive.

“Would you prefer it to be bigger, Miyu?”

A thick and long penis is a source of pride for a man. As a biological being, there’s no way she wouldn’t find it appealing.

“Well… um… considering my build…”

Miyu didn’t seem too happy about my penis getting bigger. When she says to consider her build, does that mean even this size is too big for her?

A girl without much knowledge might think my penis is big, and I understand that. But Miyu must have watched a lot of AVs for Sachiko’s education. She should know what penis sizes are like.

“Is it hard to take it in your mouth if it’s bigger?”

“That’s part of it. But also, it’ll be troublesome in the future.”

Miyu poked my manhood, her pouty expression hiding a hint of embarrassment. By “in the future,” she means when it comes to insertion, right? So, Miyu does want to have sex too.

“I’d appreciate it if you could be more considerate of girls’ sizes.”

“Uh, sure. I’ll try.”

Not like I can do anything about it, though.

“Is it still hard for you to give me a blowjob?”

“Not at all, so don’t worry.”

“Good.”

If Miyu said giving me a blowjob was tough, I wouldn’t know how to live anymore. Of course, if something happened to Miyu and she couldn’t give me a blowjob anymore, I’d still love her just as much, but it would still be sad if I couldn’t have her do it.

“While we’re at it, I want to ask: how much can you take without it being uncomfortable?”

“How much? Size-wise?”

“More like the range you can take in, or the depth.”

“Oh, I see. How much, I wonder.”

Even though Miyu has become more proactive about giving blowjobs, she usually only takes in about two head-lengths. I’m not asking her to take it all the way to the base, but I’d love to feel her mouth envelop me a bit more.

“Alright, I’ll try to take it as far as I can.”

Miyu kissed the head of my penis and slowly started to swallow the shaft, inch by inch.

“Ah… Miyu… that’s…!”

Miyu effortlessly took about 80% of my shaft into her mouth. Then, after a brief pause, she took my penis into a pleasure zone I’d never experienced before.

“Mmm… ngg… chup…”

At first, there seemed to be some resistance, but Miyu managed to take my penis all the way to the base more easily than I thought. The sensation of my entire shaft being enveloped by the warmth of her mouth and the feeling of her lips pressing against the base brought me unprecedented pleasure. More than anything, the sight of Miyu swallowing my penis whole was incredibly arousing.

“Can you give me a blowjob like that?”

When I asked, Miyu, looking up at me with her long eyelashes, nodded with just a blink. She flicked her tongue along the junction of my shaft and scrotum, slowly moving her head back and forth.

“Ah, ah…! This is insane…!”

Miyu’s lips tightened around the base, and just this alone made me feel like I was having sex with her. As Miyu sucked on my manhood, drawing out the air from her mouth, intense pressure enveloped my entire penis, sending waves of pleasure through my spine, making my hips tremble. Since we weren’t using a condom, the texture of Miyu’s cheeks and tongue directly stimulated my sensitive areas.

“This honestly feels better than sex with Yamamoto-san…”

I realized with a start that those words had slipped out naturally. Comparing sex like that was rude, yet I’d effortlessly praised Miyu’s skills without hesitation.

I was surprised at myself, but there was no time for regret. Hearing my words, Miyu’s eyes lit up with joy, and she intensified her blowjob, mercilessly attacking my penis.

“Nkk… ngg… gju… jupo… juppu…!”

“Ahh… ahh…! Miyu… haa… uuuaa… I’m… cumming…!!”

Saying it feels better than sex with Yamamoto-san makes Miyu serve me even more. My brain, simpler than a monkey’s, quickly responds to such rewards.

“Miyu… ahh… it’s so good…!! Your blowjob… feels better than anything with Yamamoto-san… I always want to be with you…!!”

Every time I said those words, Miyu happily sucked on my penis, making lewd, wet sounds without care as she continued her deep-throat blowjob. Occasionally, when Miyu swallowed, my glans would be tightly squeezed, making my hips tremble each time. It seemed her mouth was taking me all the way to her throat.

“Ah… Miyu… this is bad…!”

The urge to ejaculate was overwhelming. If I came now, I’d be shooting directly into Miyu’s throat.

I wanted to do it. Deep into Miyu’s throat. Cumming while still inside her.

“Miyu… I’m… coming…! Deep… inside… I’m cumming…!”

As I gently gripped Miyu’s shoulders, she didn’t let go of my penis. She clung to it, stroking her mouth deeply. The slippery texture of her mouth along my shaft drew out twice the usual amount of semen from my testes.

“Miyu… I’m cumming… I’m… ugh… aaaahh!!”

Throb, throb—I ejaculated deep into Miyu’s throat, and she swallowed my semen repeatedly. Her throat constricted around my penis like a vagina, milking me for every last drop.

“Haa… haa… This… is addictive…”

Once I finished, Miyu slowly pulled her mouth away, like removing a plastic wrapper.

“Cough, cough. I went all the way.”

Miyu coughed but didn’t seem in distress. Maybe my size didn’t go that deep after all.

“That was amazing. Thank you. Did it not reach your throat even at the base?”

“About a third of it was deep in my throat.”

Miyu casually dropped a bombshell. Even my size went that far? I felt the tightness of her throat, but I had no idea she was taking me that deep.

“You didn’t seem to struggle. Was I pushing you too hard?”

“Nope. I was surprised myself, but I’m fine with throat action. I can’t do it forever since I can’t breathe, though.”

Normally, people would gag, but Miyu didn’t seem to have that reflex. It felt incredible, and if it’s not a burden, I’d love for her to do it again.

“If I ask you to go deep-throat again, would you hate it, Miyu?”

“Umm… well… it’s fine…”

Her agreement was hesitant. This was the first time Miyu gave such an ambiguous response.

“Don’t push yourself, okay? I only want you to do it if you’re truly comfortable. I’m not dissatisfied if you don’t go that deep… I mean, it’s not something people usually do.”

“I’m not lying. I don’t mind going deep-throat either.”

Her answer made me happy, but I couldn’t rejoice fully. Something felt off—Miyu was clearly hiding some dissatisfaction.

“Uh… well… um…”

How should I ask? Miyu rarely avoids giving a clear answer, so I’m not sure how to handle this. But based on past experience, the most likely reason for her ambiguity is embarrassment.

Miyu might deflect, but she doesn’t lie. So, it’s true that deep-throating isn’t uncomfortable for her, and she doesn’t dislike it.

“Is it that you don’t like cumming in your throat?”

To uncover what Miyu’s hiding, I need to bring up something she hasn’t mentioned. Elimination is the best approach.

That thought was probably right, but Miyu just tilted her head and nodded vaguely. Close, but not quite. So, where’s the truth hidden?

“Is it because cumming in your throat feels good, but it’s embarrassing?”

I know it’s a harsh question, even for me, but I couldn’t think of anything else.

“That’s not it.”

Miyu denied it without meeting my eyes. She played with my still-hard penis, filling the silence, and after a long hesitation, she spoke.

“When you cum in my throat… it doesn’t taste like anything, and that’s why I don’t like it.”

Miyu mumbled, her eyes darting around.

This answer was completely unexpected.

“Is my semen that disgusting…?”

Everyone who’s tasted it has called it disgusting, so it must be incredibly bitter. Maybe she’s come to like it after drinking it so much? It’s not impossible, since Miyu’s always taken it without complaint.

“It’s very disgusting.”

Miyu rubbed her stomach and grumbled. So, it is disgusting. Well, of course. It’s not meant to be consumed.

But wait. Miyu’s never made a disgusted face when I’ve cum in her mouth. That’s why I’ve always asked her to swallow it.

“So, disliking the taste is different from finding it disgusting?”

To my question, Miyu nodded vigorously. Those were the words she’d repeated before. Now, I finally understood their meaning.

That “I don’t dislike it” was an unspoken “I like it.” It seems contradictory to like something disgusting, but they can coexist.

“I get it. Thanks for trying so hard. It felt amazing.”

Even in her excited state, she told me something so hard to say. I need to acknowledge that.

“Alright, let’s get Miyu off now.”

I grabbed Miyu’s arms and tried to lift her, but she stayed seated. Instead, she leaned forward, slipping into my lap and taking my semi-erect penis into her mouth again.

“Miyu…?”

She gripped my head with her lips and carefully supported the shaft with her hands.

“Are you still okay, Miyu?”

She must be at her limit. We’ve been teasing each other since morning, had an erotic photoshoot, and yet Miyu hasn’t climaxed once.

“Not at all…”

Miyu clutched her skirt, rubbing her thighs together. I’d never heard her voice so faltering.

“I’m so wet, I think I’m going crazy…”

Her brain was melting, and she couldn’t stop licking my penis even during our conversation. She was too excited to control herself. I need to take the lead again. Miyu’s too proud to ask for what she wants.

“Do you want to keep sucking?”

She looked up at me with glazed eyes and nodded slightly.

“Then, let’s lie down together. You can keep sucking… it’ll be like a 69.”

Miyu would keep giving me a blowjob while I’d lick her. Normally, this would lead to insertion, but I still don’t have permission.

“I don’t like that.”

Miyu’s cheeks flushed, but she firmly rejected my suggestion. When I asked to lick her before, she refused like she was swatting away a bug. I didn’t think she’d be so stubborn even in this melted state.

“Then, I won’t lick you. We’ll just face opposite directions, and I’ll only use my fingers.”

Miyu’s still not used to being on the receiving end. We’ll take it slow, one step at a time.

“I’m embarrassed to be seen…”

Miyu clung to my penis like she was sinking into a bathtub, shrinking into herself. When she’s the one being pleasured, she’s incredibly shy. It’s adorable, but it’s a challenge.

But what can I do when she’s this embarrassed?

“Mmm… hamu… chubu…”

“Ah… aaah… Miyu…!”

While I was pondering, Miyu started sucking again. I never knew she loved giving head this much. She used to hate it so much, but now she’s devouring me. Maybe it’s the rebound from suppressing her desires for so long.

“Nchu… chu… mmm… haa… haa… uu—”

Miyu squirmed restlessly while sucking my penis. Pulling her away now would be a mistake. To undress someone, warm them up first—an old saying that applies here.

“Miyu… it feels so good…!”

I grabbed her shoulders and thrust my hips forward, forcing her to take more. It’s like irrumation—forced fellatio. If she’s too embarrassed to have sex, I’ll push her past her limits until she gives in. Once she reaches her breaking point, she’ll surrender her body.

“Nmm… nnn! Nhaa… gju… jupu… nnn!!”

With each thrust of my hips, Miyu’s body trembled violently. The first time she gave head, she almost came just from having it in her mouth. Being filled by my penis must be overwhelming for her.

“Ugh… gabu… njyu… ngg!! Hau… aaau… Onii-chan… ngg… nn──!!”

Her body convulsed, and she struggled to breathe, but I kept thrusting into her mouth.

“Haa… aaah… Miyu… Miyu!!”

“Nmm… nnn──!!”

Her body jerked, her eyes unfocused. Each time I pushed into her mouth, she shuddered. Seeing her constantly on the edge was endearing, and I got carried away, thrusting in and out repeatedly.

“Njubu… aguu… ah… au…”

Her eyes glistened, and her lips, painted red, were slick with saliva she couldn’t swallow. Seeing her so undone, I forced myself to stop, controlling my hips.

I ended up pushing her to the edge, but I thought it would calm her down. Instead, her expression melted, and her arousal worsened. She rubbed her thighs harder, pressing her fingers against her crotch through her skirt. She was secretly starting to touch herself.

“Still not satisfied, Miyu?”

Her body’s trembling was the same as when she climaxed before. Her breathing was heavy, and she must be exhausted, but…

“I haven’t come… it was all edging… haa… nmm, ah, ah…”

Miyu’s hand slipped between her legs, slowly giving in to her desires. From her skirt to her panties, then directly to her clit. Her fingers slid inside, making lewd, wet sounds. At the same time, she took my penis into her mouth, devouring it without a trace of shyness.

“Zju… jubu!! Nmm… ngju… juru-jubu!!”

Miyu could barely resist her desires now. But deep down, her remaining self-control flared whenever our eyes met.

“Hagju… zuzu… zjubu!! Haau… don’t look at me like this… hamu… chubu!”

With both hands, she messed with her clit and inside her pussy, sinking into the pleasure she’d been denied for so long.

“Haa… haa… Onii-chan… aguu-njyu… abu… mju… aaah… ah… ah… it feels so good…!”

As she sucked my penis eagerly while touching herself, my erection grew harder. Miyu happily sucked me, kneeling unsteadily, prioritizing her pleasure over balance. Her desperate, single-minded focus was the ultimate turn-on, stimulating my balls.

“Ah… aaah… Mi, Miyu, sorry… I’m gonna come again…!!”

My penis shot out semen—*byu*, *byu*—ejaculating helplessly. Miyu’s relentless suction left no room for hesitation; the moment the urge arose, I was cumming. Even as I climaxed, she kept up her deep-throating, milking every last drop.

“Ah, ah, ah, I can’t take it anymore! Aaahhhh… ah, ah, it’s coming, aaah, it’s coming out!!”

Forced to ejaculate repeatedly, my vision flickered, and my head throbbed with uncontrollable spasms. Feeling my life at risk, I pushed Miyu away.

“Miyu… stop! I’m serious, I’m gonna die! Please, wait… I’m begging you!”

My desperate plea finally made her stop. Though her brain was fried from arousal, the climax seemed to calm her lust. She pulled off my penis with a *kyu-po* sound, frowning as she rubbed her stomach.

“Ugh. It really is disgusting. You produce way too much semen, Onii-chan.”

“It’s because you keep milking me dry.”

“Well, yeah.”

Miyu held my shaft softly, examining my scrotum intently.

“I always think this: there’s no way this much fits in there.”

“I think the same thing.”

For some reason, with Miyu, I surpass biological limits and ejaculate endlessly. Normally, it takes days to replenish semen, but with her, it’s like my body produces it instantly.

“Let’s take a break now.”

Miyu casually adjusted her clothes and handed me my pants. Finally, the session was over. I hope Miyu’s satisfied.

“Ei!”

“Woah?!”

She pushed me down, straddling me like a cat. I actually love this position—it’s like being ridden by a feline. Her breasts pressing down in front of me only adds to the charm.

“Ufu.”

Miyu smirked, her brain still foggy from arousal. It’ll take a while for her to return to normal.

“Haa… my stomach’s full of Onii-chan’s semen…”

She placed her hand between our stomachs, rubbing gently. Her words made it sound like I’d creampied her repeatedly, and my cock twitched again, despite everything.

“I did go a bit overboard.”

“You did, Onii-chan.”

Miyu pressed her head against me, purring like a cat, overwhelmed by the fullness. She looked so feline and adorable.

“You’re so cute, Miyu.”

“Hmm? What’s up all of a sudden?”

“The gap between your usual tsundere self and this… you’re like a cat, so lovable.”

When I blurted out my thoughts, Miyu glared at me. I thought I’d gone too far, but then she propped herself up, shaping her hands like cat paws.

“Like, *nyaaaan*?”

She was so adorable, I almost ascended to heaven right there.

“Next time, do that while wearing cat ears.”

“Ehh, no. I’m not into cosplay, you know.”

Miyu puffed out her cheeks in protest. True, frilly Lolita fashion and cat ears are different tastes.

“But you’d definitely be cute with cat ears!”

“Obviously. I’m cute, so I wear those clothes.”

Her complete lack of humility about her cuteness is actually endearing.

“If you’re already cute, it’s just cosplay, right?”

“Do you really want to see it that badly? I’m not doing it, though.”

Why ask if you’re not going to do it?

“I do. If you do, I’ll tell you you’re cute a hundred times.”

“A hundred won’t be enough.”

“I’ll spend my whole life telling you you’re cute.”

“Yeah, yeah. Onii-chan’s such a fool.”

One of life’s small joys is seeing Miyu’s not-so-displeased face after these exchanges.

“Don’t get your hopes up.”

“I’ll wait patiently.”

We’ll be together forever, after all. I won’t take this relationship for granted, but just being able to work towards happiness with Miyu is already a blessing.

“So, um, is this a good time for a kiss or something?”

As a first step towards that happiness, I had a concern: I didn’t know how to kiss. When and how should I do it? I still couldn’t imagine it.

“If you want one, go ahead. But my mouth’s still full of your semen.”

She leaned in, half-threateningly, as if to say, “Want one anyway?”

“Uh, maybe next time…”

“You should at least taste how disgusting your semen is once.”

Miyu smirked, moving her lips from my face to my neck.

“Instead, I’ll do this.”

She sucked on my neck, leaving me happily ticklish. But the kiss lasted longer than expected, and I lifted her face.

“Did you… leave a hickey? I have an offline meetup tomorrow…”

“Oh, right. Sorry. Just say it’s a bug bite.”

Later, she whispered, “I went all out,” and her playful comment, combined with her sucking on the spot again, was infuriatingly cute.

“Alright, Onii-chan. Let’s sleep.”

Miyu rolled off me and lay down on the bed.

“You must be tired, Miyu.”

“That too, but if I stay awake, I might jump out the window from embarrassment.”

“You want to pretend it was a dream.”

“Yes.”

If that’s the case, I’ll help. Miyu sleeps better when I’m here anyway. I love her bold side, but I want to respect her shyness as much as possible.

“Is it okay to sleep with your makeup on?”

“For a nap, it should be fine… I’ll pretend.”

Miyu clung to my arm with a conflicted expression. Her pride and beauty are equally important to her. It’s a tough identity dilemma.

“Just so you know, I love every version of you. Whether you’re lost in pleasure or your usual cool self, either way, I’m happy.”

I love Miyu for who she is. Every thought she has makes me love her. No matter what she chooses to be, I’ll always love her.

“Mmm…”

Miyu stared at me with a sultry gaze. I didn’t mean to say anything upsetting, but what did I do wrong?

“Uh, sorry, did I say something wrong?”

When I asked, Miyu tugged lightly on my shirt, her expression softening as she glared at me.

“I don’t want to pretend it was a dream anymore.”

It was an adorable complaint. Still, I felt bad.

“Sorry.”

“I forgive you.”

Miyu’s expression said, “Apologize by hugging me now,” so I obliged. I wrapped my arms around her, and she curled up like a small animal. Moments like these, where our preferences align, feel so natural.

“Mmm… I’m really sleepy. When I wake up, I need to take a bath…”

Her eyelids fluttered, finally surrendering to sleep. Miyu’s dere-dere (lovey-dovey) side was so cute. She’s always been energetic after sex, but I never expected such intense fellatio. And to think she liked the taste of my semen…

So, she enjoys drinking my semen, right? That’s why she kept going with the blowjob.

(Wait… does that mean…)

Miyu gets excited during sex with me because of her strong reproductive instincts as a close relative. So, her reproductive instincts are the key. That’s why she was cautious about sex with me.

There’s no need to wonder if Miyu likes my semen. Of course, she does. It’s essential for reproduction. That’s why she could drink it, no matter how disgusting. Her body accepts it as desirable.

The same goes for her abnormal excitement during blowjobs. She adores my penis, crucial for reproduction. Making it erect brings her supreme joy. Each time I made her drink my semen, the amount increased. Since she started giving blowjobs, it’s increased even more. For Miyu, oral sex strengthens my reproductive organs and increases semen—that’s why she loves my penis, loves drinking my semen, and loves giving me blowjobs.

If Miyu, who loves semen so much, becomes obsessed with sex with me, what happens? She might even poke holes in condoms to get my semen. Proof is when she gave me a morning blowjob and, driven by instincts, tried to have sex without protection.

So, what I needed to consider wasn’t just preventing Miyu from getting addicted to sex, but also managing her reproductive instincts so she doesn’t get pregnant. And to reach this conclusion, I can’t confirm that Miyu loves my penis and semen, even if it’s obvious, like today. I must never say it out loud—it’s necessary to protect her self-esteem.

(If… this is correct…)

Miyu gets excited not just from the act of reproduction, but from the idea of it. The closer it ties to pregnancy, the more intensely she’ll react.

If all this is true, what will happen when Miyu starts having unprotected sex? It’s terrifying, yet it also stirs my masculine curiosity. I resolved to be even more cautious about when we have sex.
