My Little Sister Is the Best F*p Material - Volume 5 Chapter 2: I Love You

Volume 5 Chapter 2: I Love You

The first thing I thought about when I woke up was Miyu.

Nothing special—just wondering if she was awake yet, gazing at the ceiling.

(Miyu seemed so happy when she gave me a blowjob in the hallway…)

Her neutral expression looks cold, but after all the times we’ve been intimate, I know that’s her happy face. Considering what happened after she took me to her room, there’s no doubt.

With her sensitive body, she got so aroused from the brushing that she asked to exchange panties to masturbate, just like when she was caught masturbating before. Underwear is already meant to get dirty, so she probably had less resistance. But for Miyu, who’s always careful with her clothes, it’s unimaginable—or maybe because she values her purity, she gets excited by her brother’s semen staining her clothes.

On the floor lies Miyu’s cum-soaked, crumpled panties. Last night, I drenched them with my semen and passed out. I woke up much later than our usual breakfast time. Miyu hasn’t come to wake me up, so she’s probably in a similar state.

Enjoying such thoughts, I forced my heavy body up. I was still naked below the waist since I’d given my pants to Miyu. First, I needed to change, then head downstairs.

“Miyu, you’re up?”

In the living room, Miyu was wearing an apron, pouring tea into a glass. She looked sleepy as she greeted me, so she probably woke up around the same time as me.

“Are you making breakfast already?”

It felt odd that she’d put on an apron right after waking up before I came down. But as I walked around the kitchen, I noticed her thighs were exposed under her short T-shirt.

“I came downstairs half-asleep and ended up like this.”

Miyu pulled down her too-short T-shirt to cover her hips. She was only wearing her pajama top, no panties. She must’ve been really tired last night.

“And you thought an apron would be a good substitute?”

“This is what happens when a sister is influenced by the erotic manga her brother reads.”

“I… apologize.”

I had no comeback, so I just drank some tea. Miyu tried to make a one-plate breakfast with fried eggs, but she was too sleepy and unhungry to handle it well. I wasn’t fully awake either, so I didn’t feel like eating yet. The quickest way to wake up was with some stimulation.

As Miyu moved slowly to cook, I hugged her from behind, stopping her hands.

“Hey, Miyu…”

“What is it?”

“Can I touch your breasts?”

“If you ask, I’ll obviously say no.”

“Right…”

Asking for permission means the decision is hers. If she allows it, it’s her responsibility, so she can’t complain or get angry.

So, I went ahead and touched her breasts. Over her apron, I felt the firmness of her bra and the softness of her flesh. Being allowed to touch her clothed breasts is a sign of friendship beyond sex. Even sex workers don’t let clients touch them in their regular clothes.

“They’re so bouncy, really.”

They don’t have Yamamoto-san’s volume, but their relative size and bounce for her height make them incredibly satisfying to touch. I lifted the apron, cupping her breasts and jiggling them, mesmerized by her feminine charm.

Even after last night, my penis was already swelling, snugly fitting into the crack of Miyu’s half-exposed butt. From behind, I could smell her hair mixed with the sweat from last night’s activities, stimulating my primal instincts.

Miyu just let me do as I pleased.

“…You don’t seem very into it?”

“Mm, well, I don’t mind…”

Miyu grabbed my hands, which were on her breasts, and moved them down to her stomach.

“Maybe you could hug me instead, just this once?”

Miyu’s body temperature rose slightly. She wanted cuddling over sex. She must’ve really enjoyed yesterday’s intimacy. I should’ve been more considerate.

“I love you, Miyu.”

“Nh… not that again… nh…”

Miyu shrugged her shoulders, hiding her neck and brushing off the ticklish feeling. I figured this was what she wanted, so I immediately spoke up. I’ve been waiting for her to say it too.

“So, if we do this, will you tell me what’s on your mind?”

“Probably.”

Her answer was vague. So, I called her name repeatedly, whispering “I love you” each time. We were acting like a lovey-dovey couple.

“Ready to talk now?”

“If it weren’t for the hardness pressing against my butt, it would’ve been perfect.”

“Then help me soften it up.”

The words slipped out without much thought.

“That’s a bit much during my peaceful moment, don’t you think?”

I know. I’m well aware Miyu prefers cuddling and relaxing. But I can’t calm my arousal without release.

“Maybe I should start punishing you whenever you get hard so quickly.”

“Are you serious?”

“Half joke, half because I’m embarrassed about yesterday.”

Seeming not entirely serious, Miyu lowered her posture in front of me. She was offering to give me a blowjob, so I exposed my penis and let her take it into her mouth.

She’s become so expressive, even making jokes. She doesn’t laugh, but compared to how distant she used to be, she’s changed a lot.

“Nh… chu… pu… nnh…”

Miyu’s fellatio was as quiet and steady as before, without any new techniques. I didn’t need them. Our intimacy is best when it’s almost routine. The excitement comes from having these acts embedded in our daily lives—a privilege unique to us as siblings, given we can’t have our own place yet.

“Ah, that’s good… I’m close to coming already.”

It takes some stimulation to reach the point of ejaculation, but once I’m fully aroused, I can control when I release. Clenching my hips, I can make myself ejaculate at will.

Miyu, focused on helping me, would usually want me to finish quickly after I announce it. But this time, she didn’t urge me to come. Instead, she loosened her suction, continuing her slow, steady rhythm. After enjoying my penis to her satisfaction, she pulled back momentarily before deepening her strokes for the finish.

“Say you love me again while you come.”

With that cute request, she slid her lips from the tip to the base, intensifying her technique. How could I resist? Like last night, I stroked her head as she sucked me off until I ejaculated.

“Miyu, I love you. Whether we’re being intimate or not, I’m always head over heels for you. I’m about to come, so catch it all.”

Leaning forward, I whispered my love close to her ear, triggering my mental release switch. Sensing my penis tightening, Miyu hugged my waist, filling her mouth with my shaft as she awaited my climax.

Throb after throb, my semen surged through my urethra. Even during my release, Miyu’s tongue swirled around my penis, enhancing the pleasure. Each spurt of semen was met with her licks at the tip, creating unfamiliar sensations that increased my output. She showed no hesitation in her lewd techniques, determined to extract every drop.

After I finished, Miyu remained in position, swallowing my semen and sucking out the last traces from my urethra.

“Thanks, Miyu. That was amazing.”

“It’s my duty as a sister. Though I’m glad you’re grateful.”

Miyu stood up, poured herself a fresh glass of tea, and drank it down in one go. She doesn’t perform her “duty” reluctantly; she has this mysterious sense of obligation as a sister to handle her brother’s needs. At first, I thought it was a joke about her constantly drinking my semen, but it’s probably just her fetish.

“You’ve really grown, Onii-chan.”

Miyu hugged me from the front, her hands tracing my muscles. Despite my penis constantly stealing protein from me, the hormonal surge from my awakening as a man seems to outweigh it.

“What about our promised hug?”

Miyu looked up at me, her cheeks slightly flushed, her expression serious. Still, being this close and meeting her gaze made my heart race. I’m in love with my sister.

“Gladly.”

I wrapped my arms around Miyu, pulling her close with enough force to compress her lungs. Through our clothes, I felt her slender yet sturdy frame. I was holding a girl—someone I never wanted to let go of.

There was no more room for hesitation. I was curious about Miyu’s important talk, but I had something to say first.

“I’ve been thinking about something since yesterday. Can we have a serious talk?”

I needed to confirm we were mutual. Her actions were clear, but I couldn’t rely on that alone. Even if we remained siblings, I wanted us to be honest about our feelings and love each other.

Miyu nodded, understanding my intent. We moved to the sofa. I sat deeply, and Miyu straddled my lap, facing me. It was like a reverse cowgirl position, perfect for talking eye-to-eye.

“You don’t act this clingy with anyone else, right?”

“Only with Onii-chan.”

Miyu wrapped her arms around my neck. She whispered in my ear, “Not even with friends.” I thought she might kiss me. Though she’d been physical with Haruka, she never acted this way with anyone else. That made me her only special person.

“Then I need to hear it.”

“Yes.”

I had to ask, no matter how scary the answer.

“Miyu… do you… love me?”

Finally, I said it. Our eyes locked, serious and unwavering.

“I do.”

In her eyes, I saw her emotions clearly—different from her usual coldness, filled with a girl’s warmth.

“I love Onii-chan. Hearing you say you love me makes me so happy, it feels like my throat is burning. I love you so much.”

Until the last word, her gaze never wavered.

I had so many questions—when did she fall for me? Did she see me as a man?—but her answer was all that mattered.

“I love you too, Miyu.”

No matter her past intentions, I’ve decided to trust her. I want to love her as a woman, with pride.

“Hehe. I know.”

Miyu smirked, sandwiching me between her arms and breasts. Her bust made it hard to breathe, but it was a happy struggle. For Miyu, who avoids physical contact with others, this was her greatest expression of love.

“It won’t amount to much, but it was when I fell for you that I started looking for a girlfriend.”

She’s known my feelings for over two months.

“Onii-chan, did you actually play those erotic games?”

“Why bring that up now?”

“Because Onii-chan has no clue about a girl’s heart, and it makes me sad.”

Miyu faked a dejected look. Unfortunately, eroge wasn’t a good guide to romance. If only it gave me choices like in a game.

“I already know you love me, so you can tell me as much as you want. That’s why you said it this morning, right?”

“Right. Got it.”

She fell silent, and we locked eyes. The long silence made her expression tense.

“Sigh… it’ll take Onii-chan another hundred years to understand a girl’s heart…”

“W-Wait! Was that the wrong thing to say? Of course, I—”

“Never mind. It’s meaningless without the right mood.”

What happened to “as much as you want”? But she’s right.

“I just realized, if you love me this much and are so affectionate, does that mean you’re not worried about us being siblings anymore?”

“We’re still thawing, to be precise.”

Miyu clung to me even more.

“So keep warming me up.”

She looked at me pleadingly, as if asking, “You get it now, right?” I held her in my arms, repeating my words of love and stroking her hair.

Once the thaw is complete, Miyu will no longer refuse sex with me, but strangely, I didn’t feel the need to rush it. I have a possessive desire to make Miyu mine, and I want to mark her as mine by taking her virginity. But I’m not fixated on intercourse. Our relationship started with my masturbation, so sharing my semen feels more significant than physical connection. Since we’ve already done that, my heart is at peace now.

“Then, it’s my turn.”

Miyu slipped out of my arms, taking a moment to cool her flushed face. Finally, I’d hear her important talk.

“What I’m about to say is the conclusion I’ve reached after months of struggling. I don’t expect you to answer right away… but…”

Her tone shifted, and she held my hand, her voice filled with sorrow.

“Please don’t forget how happy I am right now. From the bottom of my heart, I’m overjoyed that we’re mutually in love. Just believe that.”

—Even if you come to hate me.

Miyu prefaced her talk this way, indicating its seriousness.

But seeing her distressed face, my heart remained calm.

“I’ll never hate you. I know it’s not something to say lightly, but I mean it.”

—I’ll always love you.

Even if the truth hurts me deeply, I vowed to stay true. My heart didn’t waver.

“Then I believe in you too.”

Miyu’s voice softened, as if a weight had lifted.

“You see…”

Taking a deep breath, she finally spoke.

“I’m extremely uncomfortable around men.”

The truth Miyu revealed.

“…I see.”

Strangely, I already knew this. But I hadn’t fully understood. I’d overlooked this critical fact. Yet, it was something that couldn’t be ignored.

—Because…

“I’m a man, though.”

Yes. No matter how I rationalize it, I’m a man. Miyu dislikes men, yet she loves me, a man. If both are true, her conflicting feelings must have been a serious struggle.

“Yes. You’re the only special person to me. But this ‘special’ isn’t all good. It might even hurt you.”

Miyu hinted at the outcome with vague words.

“When I showed you my closet, I told you why I stopped wearing cute clothes, right?”

“Yeah, about your teacher and mom telling you to stop, and you crying on your way home.”

“Right. There’s more to that story.”

Miyu was always a model student. For her to be scolded by both parents and teachers, something serious must have happened.

“I was fighting with some boys back then. Several of them ended up in the hospital for checkups.”

She came out swinging. What kind of intense battle was that?

Still, the cause was a fight with boys. The rumor Yuka told me was true.

“Five upperclassmen. They were all in clubs, so their parents complained fiercely about their injuries. I was still young then, so being scolded by so many adults was unbearable.”

Wait, Miyu was in third grade then. How did she win against upperclassmen athletes?

“You weren’t that good at sports, were you?”

“Not really. But fights are different. It’s about determination.”

“Like a shonen manga…”

But after knowing her these months, I could believe it.

“The fight started because one of them confessed to me. He was good at sports, had great grades, was handsome, and a bit of a troublemaker. Even at that age, he was already experienced.”

Those upperclassmen were around my age. Maybe even classmates. There are amazing people out there.

“He was popular with girls, and many wanted to date him, even as a backup. When he confessed, I rejected him instantly.”

“Why?”

“He disgusted me.”

Miyu clarified that her disgust wasn’t about his behavior or her health.

“I thought he was fine from a distance, hearing about him. But the moment he confessed, I instinctively knew he was impossible.”

That was the moment Miyu clearly realized her aversion to men—her straightforward feeling when she only had an innate dislike for them.

“The boys who witnessed the confession started taunting him for being rejected, so he got angry and came at me aggressively. I beat him up with a pointer and a chair. Then his friends got mad at me for some reason, so I neutralized them too. It was self-defense.”

“Uh…”

“So, it’s justified.”

“I believe you, but…”

I understood the fight, but why were the teachers scolding her about her clothes?

“What about the clothes?”

“They were just noticeable. I’d been targeted before, but since I was a model student, it was overlooked. After that incident, they started saying, ‘It’s your fault for wearing such clothes to tempt boys,’ so I stopped wearing them in public.”

Ah, labeling her like that. No wonder a child under ten would hate it.

But this was mostly what Yuka had told me. Surprising, but not incomprehensible.

“So, the key point is what comes next?”

Miyu sat on the sofa, straddling my lap. She slowly nodded at my question.

“After that, countless boys confessed to me. But I couldn’t even consider dating any of them. Eventually, I grew tired of being confessed to and became a bit cold-hearted.”

She pressed her chest against me resentfully, making me feel apologetic on behalf of all men.

“Girls with your figure tend to get attention.”

“I know. I don’t get why anyone likes these uselessly large things.”

Sorry, but I can’t agree with that. All we men can do is sympathize.

“Is that why you dislike your breasts?”

“Half of it. The other half is because I can’t wear cute clothes.”

Recently, her chest grew so much that even her lolita dresses needed custom orders, making her even more dependent on Haruka.

“Is that financially manageable?”

“I keep telling Haruka that my chest grew because she played with it too much, so it evens out.”

“Fair enough.”

She’s so resourceful. I admire her.

“Anyway, back to the story. I thought I might be a lesbian since I couldn’t like boys. I didn’t mind being touched by girls…”

But she couldn’t fall in love with any girl either, so she concluded she wasn’t a lesbian.

“Living like that, unable to love boys or girls, I was deeply troubled. And then…”

Miyu’s voice grew intense, her eyes sharp as she looked at me. I already knew what she was about to say.

“I saw you, in the next room, masturbating to a girl with a name similar to mine. The title was something like ‘My Brother and Sister’s Childmaking Declaration I Oblige My Brother to Cum Inside Me!’ And the heroine never got pregnant. What a terrible game.”

She knew the details, probably from when she researched it.

“Looking back, it was a terrible situation.”

“It was worse than that. Can you understand how I felt?”

“I deserved to be hit with the computer…”

“It was that bad.”

Miyu looked away, her voice calming.

“But what truly shocked me was what happened next.”

Yes.

That was the beginning of everything.

“I felt nothing watching you masturbate alone.”

No matter how you look at it, it’s a disturbing situation: a brother with creepy habits, and a sister who, despite her dislike for men, found herself accepting her brother’s masturbation. This very event led to the conversation we had yesterday.

“Not only that, I even became curious about what you’d do next. I couldn’t even imagine other boys naked, let alone think about them.”

That’s why Miyu did what she did—helping me with my masturbation, an act so incomprehensible. But in reality, no one was more confused than Miyu herself.

“I wanted to understand what that feeling was. So, I kept asking myself, how far could I go without feeling disgusted?”

After that, Miyu gradually closed the distance between us, eventually even giving me a blowjob. It was then that she seemed to confirm she could only accept me as a man.

“So, you drank my semen to confirm that too?”

“I guess you could say that. Though the first time was more… impulsive.”

On top of everything we’ve discussed, Miyu’s involuntary physical reactions—how she gets unusually wet during our intimate moments and how her sexual impulses run wild when we touch—all point to one undeniable conclusion.

“In other words, I’m the opposite.”

Miyu felt disgust at the confession of an excellent, masculine boy, preferred being touched by girls rather than boys, and yet, she found herself sexually interested in only one person: her own brother.

At first glance, Miyu’s explanation seems inconsistent. But when viewed through the lens of reproductive instincts, a connecting line emerges.

“My biological preservation priorities are clearly different from others. The vector my instincts point to is the opposite of what’s considered normal.”

Miyu’s instincts choose a mating partner who is genetically close to her. With her parents rarely at home and me taking care of most household chores, I was the closest relative to her. Even compared to our parents, who share half of her genes, my genetic structure might be closer to hers.

“I couldn’t believe it at first. So, I’ve been testing, step by step, how far I could go with you.”

And so, Miyu began engaging in intimate acts with me, despite her resistance to the idea of sibling relationships.

“In the end, instead of hating it… I realized I was unconsciously seeking these acts.”

No matter how much her mind told her it was wrong, her body craved it. And eventually, she would cross that line.

“I see…”

The questions have been answered. I finally understand Miyu’s true feelings. On the surface, I’m glad we had this conversation.

But honestly, it’s painful. The truth is far more cruel than I could have imagined. Because it negates the most important thing to me: Miyu’s confession of love.

Miyu didn’t choose to love me; she was compelled to. That’s the truth derived from our conversation.

How can I respond to Miyu’s words? Hearing this “important talk” won’t make me hate her. I can still swear to that. But no matter how much I try to deny it, one thought keeps flooding my mind:

—Miyu is such an unfortunate girl.

“Yeah, you get it. You’ve got that ‘I understand’ look on your face,” Miyu says, peering into my eyes. Despite everything, she’s still smiling—not forced, not resigned, but genuinely innocent.

“It must be tough for you. Go ahead and worry all you want. You’ve been pushing your desires on me while I’ve been struggling all this time.”

“Ah, yeah… I’m really sorry about that. I just couldn’t control myself sometimes…”

Maybe it’s the same for me—I can only find release with Miyu. If we look at it that way, I might be the one who understands her best.

But my situation and Miyu’s are completely different. I was just an ordinary otaku who could only fall for someone as beautiful as Miyu, while she, despite being cute and talented, could only fall for someone as much of a failure as me.

No matter how you look at it, it’s unbalanced. I’ve received so much from Miyu, while she’s lost countless opportunities she should have had.

“I guess I’m pretty unlucky in your world,” Miyu says, her voice oddly cheerful. With a carefree smile, she takes both of my hands in hers.

“You seem pretty happy about it.”

“Of course. Because I’m happy in my world. I’ve already found my answer.”

I feel Miyu’s warmth through her hands. The hands I’m holding now are the same ones I vowed to cherish just moments ago.

That’s right. I shouldn’t be moping like this. I need to find my own answer to make Miyu as happy as she feels.

“Can I have a little time?”

“Sure. I’ll wait until dinner tonight.”

“That’s it?!”

It took Miyu three months to figure this out. Even with the hints she’s given me, there’s no way I can come up with an answer that quickly.

“Because I want to sleep with you tonight.”

“I never said you couldn’t.”

“Just sleeping together isn’t enough, you know.”

“What do you mean?”

“Figure it out yourself.”

Miyu taps my forehead and bounces off the sofa. For some reason, this exchange sends a chill down my spine—not because of what Miyu said, but because I’ve realized something far more terrifying.

“I’ll wait until eight o’clock for dinner. So, you need to show me what you’ll do to make me happy,” Miyu declares.

“What if I can’t figure it out?”

“I won’t do anything. Things will just unfold as they will. Whether you search for the answer or not is up to you.”

Miyu sweeps her hair to the side and adds in a mature tone, “But I want you to make me happy. The choice is yours. If you give up on me, I’ll cry a little.”

Miyu ends the conversation as if she’s not worried about me giving up at all. Summarizing her words, it’s clear: “I won’t let you off the hook until you find the answer, so give it your all.”

“I’ll definitely find the answer. Wait for me.”

If that’s the case, no matter how much I have to crawl, I’ll find a way to make Miyu happy.

No matter how complicated things get, this much is certain:

I love Miyu more than anyone else in the world.
