My Little Sister Is the Best F*p Material - Volume 6 Chapter 05: My True Feelings, Unmasked

Volume 6 Chapter 05: My True Feelings, Unmasked

“Well, this should do for now.”

I folded a face towel from the hotel into a long strip and wrapped it around Yuka’s head to cover her eyes. It was a bit short for a blindfold, but it should stay in place unless we tried something like missionary.

“First off, blindfolding heightens anyone’s sensitivity, so unless you make me feel good enough to climax, it doesn’t count, even if it feels a little better.”

Yuka was kneeling on the bed, talking to me from behind her. Seeing a skinny girl like her blindfolded and kneeling like this made her look like a frail, unfortunate girl tamed by a slave trader, which stirred a sadistic itch in me.

“How am I supposed to tell if you climaxed?”

“I’ll raise my hand and say, ‘I came!'”

“Seriously, you…”

“Look, it’s not like I’m going to climax anyway, so don’t sweat the details. You’ll know it when you feel it.”

“Fine, but if it happens, be honest about it.”

If Yuka refused to admit defeat, I’d end up tied up and at her mercy, so I’d prefer a clear standard for judging. That said, I was in the mood to fool around with Yuka today, so I wasn’t exactly motivated to push too hard.

“Just so you know, if you hurt me, it’s an instant loss for you, big brother.”

“That’s totally stacked against me!”

“You’re the one saying rude stuff like I can only get off on punishment. If you want, instead of this weird experiment, you could give me a deep, passionate kiss, and I might just forgive you.”

“Pass, somehow.”

This contest won’t end unless Yuka admits defeat. It’s practically a scripted loss at this point. Can I at least keep this to some light SM play and wrap it up amicably?

“Also, if I end up feeling good from this, that’s a whole other problem.”

“Yeah, no kidding.”

If she told me to take responsibility for that, it’d be Miyu and her group’s fault, not mine. I silently waved my hand in front of Yuka’s face to confirm she couldn’t see, then tied her wrists behind her back with the face towel, twisting a hotel hairband over it to make a makeshift restraint.

“It’s surprisingly tight.”

“You could pull your arms free if you tried, but with the tools here, I can’t tie you up completely. Don’t overdo it.”

Now, I could push Yuka down and take her from behind, but unfortunately, my erection had wilted again. Should I touch her body to get myself going or have her get me hard with her mouth? Since it’s punishment vibes, the latter feels right.

“Yuka, sorry, but can you use your mouth again?”

“How many times are you gonna make me do this? It smells like rubber, and I hate it.”

Yuka turned her face away from the sound of my voice. Fair enough—making her lick something that had a condom on it felt harsh. I decided to wash up in the bathroom.

“Wait, where are you going?!”

“To clean up in the bath.”

“Do that before tying me up! What kind of nerve do you have, leaving a girl like this?! Hey, come back!!”

Yuka yelling complaints at an invisible target was kind of amusing, so I quietly headed to the bathroom. For her sake, I’d wash thoroughly.

“Oh, forgot the bath towel.”

I’d left it on the sofa after getting out of the bath. Might as well hang Yuka’s towel up to dry while I’m at it.

“Oh, you’re actually back. Hurry up and get ready. If you can’t get it up, just take some Viagra.”

When I returned to the room, Yuka was talking big all by herself. The point of this was to test if simulated punishment heightened her sensitivity, but I didn’t want to torment her. I wasn’t into just ignoring her for some neglect play.

“Yuka.”

“W-What?”

Her voice paused, a mix of relief at my response and unease at me calling her name so curtly.

“I’ve been with my share of girls, but somehow, I think I like blowjobs the most.”

“So what?”

“Just felt like saying it.”

With that, I headed to the bathroom. Sex is about giving and taking. Even in SM play, without trust and care, you can’t find real pleasure. If Yuka’s defiant attitude isn’t just her being a jerk, she’d pick up on what I meant. I think she’s the type who can read people’s feelings.

In the bathroom, I carefully washed my lower half, dried off with a bath towel, and used a hairdryer to get rid of any moisture. Back in the room, Yuka was still kneeling on the bed, squirming.

“What’re you doing?”

“N-Nothing.”

She stopped moving when I spoke. I expected more complaints about being left alone, but she was surprisingly quiet. Could she already be getting in the mood? No way it’s that easy.

“Even if we’re recreating punishment, I’m not trying to violate you, okay? It’s just for show.”

“I get it.”

I climbed onto the bed, grabbed a condom from the side table, and tore the packet open. In front of me was a naked girl, hands tied behind her back. Her legs were spread slightly to balance on her knees, and I caught a glimpse of faint pubic hair I’d seen before. It had a slight brown tint, so her bright hair must be at least partly natural. Yuka’s slender body, compared to the voluptuous duo who were like walking erotica, had a strange realism to its slightness.

“So, how am I supposed to give you a blowjob like this?”

“Lean forward first. I’ll guide you with my hands.”

“Like… this?”

As Yuka lowered her face, I touched my half-erect penis to her lips. She stuck out her tongue to feel its shape, then took the tip into her mouth, sucking it in deeply. A blindfolded girl burying her face in my crotch to lick me, even if it’s reluctant bondage play, was undeniably arousing.

“Nn… aa… mugu…”

My penis quickly grew in her mouth, but Yuka didn’t stop right away. Maybe because I said I liked blowjobs, she kept at it, working my fully erect penis despite her unsteady position.

She didn’t want to be seen as bad at this, so even blind, she licked and explored with her tongue. Using her core muscles while struggling to breathe, her breaths grew ragged. Moving her head back and forth, she sucked my precum with her tightened lips. After a few minutes, my erection swelled to its limit, the head bulging, and she finally pulled her mouth away.

“Ugh… somehow, this feels even more humiliating than before.”

But I could sense some effort to please me while she was at it, so I was satisfied. Satisfied, but… an emotion I didn’t want to feel started sprouting in me.

“Stopping makes it go soft. Once we get to the main event, your mouth’s free, so talk then if you want.”

“Ugh… you…!”

Yuka gritted her teeth and glared, then steadied her breathing, found my penis with her tongue again, and reluctantly took it in. She’d played games with Miyu before and understood turns. Essentially, “I followed your orders quietly during my turn, so you’d better follow mine just as much.” Even if it’s something she doesn’t want, she’ll go along to an extent to make her point.

“Hamu… guju… nku…”

“You’ve gotten pretty good in such a short time.”

Maybe it’s just my arousal in this situation, but her blowjob felt way better than the first time. I’d made her swallow during past punishments, and her body seemed to remember, making it dangerously easy to lose control.

Especially once we get to the main event, I need to avoid thinking about the times I punished her on Miyu’s orders. If I finish too soon, Yuka might nitpick and end my turn.

“Chubu… guchu… makin’ me… do this… ugh… don’t think… I’m happy… being praised…”

“But it does feel good, doesn’t it?”

Her tone was grumpy, but the fact that she kept sucking sent waves of joy and pleasure through me.

“Hamu… nguju… I’m totally… gonna get you… later…”

Her twin tails swayed with the movement of her head as she serviced me with her mouth, hands tied behind her. Her hips moved up and down in sync with her head as she took me in. Watching her ass, the urge to take her grew stronger.

“I’m putting it in now. Time for the condom.”

“Nn… zujuu… chupa. Fuu. Hurry up and finish this, okay?”

Yuka stopped the blowjob and sucked up her saliva. I checked the orientation of the condom from the packet, put it on my penis, and moved behind her. To have sex with Yuka, whose hands were tied, in doggy style, I’d have to make her lie face-down on the bed. That much was probably necessary to keep the punishment vibe.

“It’ll be tough, but bear with it.”

I pushed Yuka’s back, making her head touch the bed, then grabbed her hips and yanked them up. Looking down at her squirming, head sinking into the bed, face turned sideways to breathe, I lightly inserted just the tip into her entrance.

“Ah…”

A faint, sultry sound escaped Yuka’s lips. Her passage, compared to our earlier sex, was now overflowing with love juices.

“Did you just make a sound?”

“I-I don’t know what you’re talking about.”

Yuka’s voice sounded flustered. She probably hadn’t expected her sensitivity to spike this much. It already felt like we’d passed the “slightly better” threshold, but Yuka clamped her lips tight, insisting she hadn’t made a sound. Pressing her now would probably just get me brushed off.

“I’m starting now.”

I shelved my doubts for the moment and proceeded with the sex. Whether Yuka had awakened to masochism would become clear once I was inside.

Gripping her hips again to signal the insertion, I thrust my penis, which had only been at the tip, deep into her vagina with a zupu.

“Hya… nn, ah…”

When my penis nudged the entrance to her womb, Yuka let out another faint moan. Biting her lips, she desperately endured the pleasure that hit her two, three times with each thrust.

“Fuu… tsu… u…”

Yuka managed to hold back from making any more sound, breathing roughly. Hadn’t I proven that I was right at this point?

“Does it feel good?”

I asked Yuka as I gradually increased the speed at which I moved my hips.

“Hafu… n-no way… being put in this humiliating position… there’s no way I’d feel good…!”

Bound at the wrists, ass thrust upwards, slick honey dripping from her most secret place, Yuka still stubbornly denies any pleasure. If the sensitivity were truly the same as before the restraints, she’d be riding me, smugly taunting me with “See, I told you so!” Instead, Yuka just huffs, her breaths ragged, utterly silent. It’s as if even attempting to speak would unleash a torrent of ecstatic moans, so she’s desperately trying to shrink into herself, preventing her vocal cords from betraying her.

And then, the only sounds between Yuka and me were my own increasingly rapid breaths from the exertion of sex, and the wet, bubbly sounds of air mixing with Yuka’s overflowing love juice. Her face was buried in the bedsheets, yet her expression was undeniably slack, lost in the throes of pleasure. There was no other way to interpret it.

“Starting to feel good yet?”

I asked, and Yuka took about ten seconds, carefully measuring her breaths, before finally managing to speak.

“It… it just feels like there’s a… a stick inside me, that’s all… Just… how… ahh… bad… are you at… s-sex?”

Her voice was higher, more strained than usual, but Yuka still desperately clung to her composure. She was so wet, there was no way she wasn’t enjoying herself, but her pride wouldn’t allow her to admit defeat.

“Lying to me will only make me harsher, you know.”

Smack! I delivered a sharp slap to Yuka’s ass. A faint red handprint bloomed on the pale white curve of her buttocks.

“Hyaa… ah… ah…!”

Yuka’s voice cracked, and her vaginal muscles clenched tightly. As if to force open that wall of resisting flesh, I ground my throbbing cock against her, repeatedly slapping her ass.

“Ah, hii… unhya, s-stop… hyaa…!”

With each thrust, Yuka’s insides became increasingly softened, looser, a veritable masterpiece of carnal delight. It was incomparable to our vanilla sex; her inner walls were clinging, sucking, drawing my cock deeper. Her love juice wasn’t just lubrication. It filled every space, creating a seal, allowing her vaginal muscles to caress and devour my shaft with every movement.

“Ugh… ah… aggh…!”

Yuka tilted her head back, forcing a moan down her throat, her toes curled upwards, her bound hands clenched with desperate force. She couldn’t suppress her cries any longer.

It was only a matter of time before Yuka admitted her pleasure. But my own need to unload was reaching its breaking point, too.

As I continued to thrust, the softness of Yuka’s cunt started to resemble the tight, broken-in feel from that time I stole her virginity when she was drunk and stuffed in a cardboard box. Unbidden, Miyu’s voice, whispering “Give it to me,” echoed in my mind. How could I possibly hold back like this? I had to get Yuka to admit defeat before I blew my load.

“You’re enjoying this, aren’t you, Yuka? Just admit it already…!”

“Haa… ah… hauu… n-no… I… this isn’t… pleasurable… augh… It’s not enjoyable… at all…!”

Even as I slammed into her, the wet, squelching sounds of our bodies colliding filling the air, Yuka stubbornly refused to yield.

“Aahh… ah… aaugh…!”

Yuka’s muscles twitched, her inner grip tightening with sudden intensity. She was close to coming. If I could just push her over the edge, even Yuka wouldn’t be able to claim victory. I pushed back the urge to cum and focused on the act, relentlessly thrusting into her. It was almost brutal, the way I was driving my cock into Yuka’s womb.

“Ah… aggh… ugh… ugh…! It’s n-not… Ahh… Aahh…!”

Her body bucking and trembling, Yuka still resisted. But the command to ejaculate had already been sent from my brain.

I grabbed Yuka’s hips, covering her lower abdomen, and, with the sperm already approaching the urethra, I ravaged her cunt with all my might.

“Yuka… Yuka…!”

“Aaaaah… haa… ugh… ah, haa… stop… s-stop it… l-l-let me… ahh… n-no way… Aaaaaaah!!”

Byuku, byururu, byuku, byu…!

As if to force every last drop of sperm into her womb, I slammed my cock as deep as it would go. In the next instant, Yuka’s back arched violently, her body shuddering uncontrollably.

We both gasped for air, our bodies slick with sweat. Yuka’s mouth hung open, her breathing shallow like a panting dog. She had been so focused on suppressing her moans that she hadn’t been breathing properly.

It was clear now. Yuka was only truly aroused by being punished or forced. Knowing this didn’t solve anything.

“…You came, Yuka, so that means I was right this time, at least for now, right?”

I pulled off the condom, knotted the end, wrapped it in a tissue, and tossed it in the trash. I needed to confirm the facts first, then figure out how to create satisfying, lovey-dovey sex for Yuka. I didn’t know what exactly was bothering her or how to fix it, but I had to avoid ending things with just punishment sex and making her the same as Miyu.

“I… I didn’t… come…”

Her body still trembling, the aftershocks of pleasure still rippling through her, Yuka managed to turn her head slightly and speak, her voice shaking.

“It’s not over until you admit it, Yuka. Honestly answer that the sex was good and you came.”

“After being so… humiliated… how could I… possibly… enjoy it…! Let alone… come… there’s no way…”

She’s still resisting, even after that blatant orgasm? I anticipated it, but dealing with it in practice is proving difficult.

“M-More importantly, you came, didn’t you, Onii-san? I heard you take off the condom and grab a tissue. So, that means I win, right?”

Yuka raised her bound hands, demanding to be released. I couldn’t let her have her way here. If I didn’t break her stubbornness, this pointless back-and-forth would continue endlessly.

“If you won’t admit defeat, I’ll keep going. You don’t think one round with me is going to be enough, do you?”

“Huh…? What… that’s… unfair…?”

“It’s not unfair. Now, clean this up for me.”

I brought my still-hard cock close to Yuka’s mouth. She wrinkled her nose at the scent of the semen-slick shaft, fresh from the condom.

“No way, I’m not doing that. I can’t stand the taste of semen and rubber… mgh…!?”

Ignoring her protests, I shoved my cock into Yuka’s mouth. Once she registered the firmness of my erection, she seemed to understand that the sex wasn’t over yet, reluctantly giving me a cleanup blowjob. She avoided using her teeth, cautiously sucking on my cock, licking off the semen.

I couldn’t let her go down the same path as Miyu, but I couldn’t imagine a future where letting Yuka do whatever she wanted would improve the situation. So, first, I had to completely defeat her.

“Ugh… ugh, slurp, chup… haa, aggh…! Ngh, jupa… mhaa, ugh. You just came, but you’re still so big? Are you crazy? How much do you love raping women?”

“You helped make me this way, Yuka. I’m starting another round.”

I put a second condom on my cock.

“Can you give me a little… break? If you use my kitty now, things might get… a little messy…”

“If you can’t, I’ll just make you do it in your mouth. Is that what you want?”

“No, no! But… I really can’t right now! Please, let me rest…”

“If you didn’t come, you can keep going.”

I moved behind Yuka, grabbed her ass cheeks, and spread the lips of the hole I’d just been plowing with my thumbs. An unchanged amount of love juice overflowed from within.

“H-Hey, stop it! You think you can do that and get away with it?!”

Yuka cried out, sounding like a captive princess, her emotions intensifying as sweet honey dripped from her parted lips. Even this seemed to arouse her. I placed a finger on her asshole, spreading it wide enough for air to enter her intestines.

“Hyaa… stop it, stop… don’t look at me there…!”

Just as I expected, Yuka’s cunt gushed with even more love juice as her asshole twitched. She was so responsive to discipline. I felt like I could lose sight of my goal and get hooked if I kept going.

“If this had been developed by Miyu and the others, I might have tried using it.”

I knelt down, regripped Yuka’s thin ass cheeks, and thrust my cock into her pussy without a moment’s hesitation.

“Higii…!! A, aaaaah… n-ah, hyaa…! N, auuu… hauu… ah, ah, auuu aah!!”

Yuka writhed violently, her lustful moans echoing through the room. Only when the sound entered her own ears and her brain registered it did she stop breathing and suppress the cries. Because I had started sex before she had fully processed everything, Yuka had forgotten that she wasn’t supposed to moan.

“If you’re making noises like that, you must be enjoying it, right?”

“Haa… huu… I… I’m not… ugh… nga… n-not at all… I’m not enjoying it…!”

“How long are you going to be so stubborn?”

I churned her now even wetter honey pot with my cock, and Yuka’s whole body twitched again as if she was about to come. Even though she knew she shouldn’t, Yuka was finding it increasingly difficult to suppress her moans.

By actually having sex, I’d come to realize that the erotic scenes in H-games and anime were just fantasies to arouse men. Still, there was one piece of knowledge that applied to both 2D and reality. And that was that once a girl reached climax, the interval until her next orgasm shortened. Her body, accustomed to coming, would start preparing for the next orgasm as soon as I thrust my cock back inside.

“Augh, haa… haa… huu… ngh, ihya, aah… stop it… augh… p-please, let me rest… nngh… aaaaah…!!”

Yuka endured the pleasure assault, saliva beading at the corner of her mouth. I grabbed her arms with both hands, holding them like reins, and increased the force of each stroke, pounding her insides repeatedly. I would treat her cunt like a toy, continuing this selfish, male-centric sex.

“Feeling good, Yuka…?!”

Each time I asked, I tugged on her arms harder and thrust more violently. It was clear I wasn’t even expecting an answer, as I roughly slammed my cock in and out.

“Aah…!! Hii, a, it, feels… so goood… yaa hiiii…!! Ungh, ahn, ah… hauu…!!”

Unable to resist the building pleasure, Yuka’s sensitivity escalated even higher. Her body began to convulse, on the verge of a second orgasm. I stopped moving completely, remaining connected to her. During that suspended moment, Yuka’s body was enveloped in the afterglow of pleasure, while her brain, which had been mindlessly succumbing, cooled down.

When her breathing evened out, I resumed, reveling in her frenzied moans as I rubbed the head of my hard cock against the walls of her cunt. As my thrusts gradually became faster, her body started to spasm again, and just when she was about to cum, I stopped moving. I repeated this again and again until, eventually, Yuka continued to move her hips even when I stopped pumping.

She wanted to cum, but I wouldn’t let her. So, she tried to reach orgasm on her own. That was all that remained in her clouded mind.

“Augh… haa… ngh…”

“Want the stimulation so badly that you’re moving on your own now?”

“T-That’s… not it… um…”

Hesitant at my question, Yuka stopped moving for a moment, then, as if struck by an idea, began to thrust her hips deliberately.

“It’s because you’re being so… rough… ungh… ahh… I’m just… cushioning the impact… angh, aaangh…”

Yuka thrust upwards, her ass in the air, as if she were masturbating against a textured wall. I’d pushed her this far, but if I gave her room to make excuses, she’d get away with it. I tried to think of a clever way to trick her into digging her own grave, but it seemed I needed to get her even more lost in pleasure to steal away her thoughts.

“Yuka. Turn around.”

I pulled out of her, then rolled Yuka over onto her back. I lifted her limp, heavy upper body into a face-to-face position. Her pigtails, which had been styled into curls, were now limp and straight.

“Hwa… what… are you going to… do…?”

“Nothing. Just keep having sex.”

“Ugh… a, ungh… ihyaaaa…!!”

I inserted my cock from the front, using her body like an onahole, pumping up and down, thrusting deep to the base. Inserting from above stimulated the cervix more, and Yuka’s sensitivity was on a completely different level. The pleasure I received was also greater, making it harder to hold back my ejaculation, but all that was left was to persevere.

“Ah, aahugh, aahhyaaa…! Th-This is… unfair… ah… ahiii… aaaaughaaah…!”

With a hard cock pointing nearly straight to the ceiling, I grinded my hips, repeatedly stimulating her sweet spot, as if gouging out her insides from within. I squeezed the muscles in my body, and without a pause, I struck her womb so hard, it gave her no time to breathe.

“Auuuaaaah, anngh, hihyaaa…! Aah… guhyaiaah… iihigiaaaah…!!”

Even as Yuka’s body arched and her moans broke off, I continued. No matter how many times she came, I wouldn’t stop pumping. Even though she was orgasming so hard she was about to lose consciousness, I continued to pour all of my lust into her.

“Yuka… Just be honest…! Haa… Say it… say you feel good…!”

“Ihyaaaa, no, yaangh ah… I won’t, i… ungh… I won’t adm…!!”

Yuka stubbornly continued to deny it. All her attention was focused on not saying yes. No matter how much I made her moan, it was useless. No matter how many times she came, we’d just keep repeating the same conversation. As I watched her steadfast refusal, something suddenly came to mind.

“…Yuka. We were supposed to be having lovey-dovey sex, remember?”

I slowed my thrusts, holding Yuka in my arms, her mind in a daze. Yuka reacted to those words. I had originally started this punishment play to see if Yuka couldn’t enjoy sex any other way. And now, it was clear that Yuka had a masochistic fetish. If that was the case, all that mattered for the rest of this sex was for Yuka to admit that she felt good.

“If you stop lying, Yuka, I might kiss you.”

It would only be a light touch of the lips, but that should be enough to create the illusion of a lovers’ intimacy.

“Y-You’ll… kiss me…?”

“If you’re honest.”

I said only that, and then I continued the sex. I wouldn’t use any more force. If Yuka didn’t admit defeat, I’d admit I was wrong. It was with that resignation that I sent one last, very normal piston stroke into her cunt.

“Aah… ungh… aaaaah…”

“You have such a cute voice now, Yuka… Does it feel good…?”

“Ah… it, it feels good… ungh, it feels goood… ah, ah… Onii-san’s sex… feels so good…!”

“Haa… it’s… better for you when you’re honest… ungh? Huh? It feels good?”

After being so stubborn in her denial, the girl flipped her hand with ease.

“It really feels good? This is what you want?”

I thrust deeper, penetrating her to her core, making sure Yuka understood the hardness of my cock.

“Ah… aaanngh… Onii-san’s hard thing… feels so good… I love it…!!”

Her expression was completely different from before, now melting into a blissful reverie as she accepted my cock. She leaned the body I was holding towards me, and she moved her hips as if to ride me.

That was it. If she decided it would benefit her, Yuka was the type of creature who would change her behavior without any shame or concern for appearances. In the end, she got to have sex with me, got to be kissed, and the battle ended with nothing but positives for her. However, after all the trouble I’d gone through, I wasn’t going to let her be the only one who enjoyed this.

“So, does that mean that what you were saying until now was a lie?”

“Ah, ah, hahii… it was a lie… I’m sorryhiyai…!”

Yuka thrust her hips, not showing any remorse. At that point, I couldn’t help but want to punish the impertinent woman.

“You always get carried away like this…!”

I violated Yuka’s cunt with all my strength. My cock, hardened by irritation, rubbed against her sweet spot. Even knowing that my roughness was arousing her, I couldn’t stop the explosive sounds of my hips slamming against hers. Pang! Pang!

“Aah… hiiyaa…!! Auu, I’m sorry, hiyaaa… ah… aanh… I won’t say anything… more, ever, ever… again, hieen… dehiii… ngh aaaahh!!”

Yuka soaked the blindfold with her tears, screaming with a relaxed expression and a sweet voice. I wasn’t able to push her to the breaking point like Miyu. So, the wicked woman kept repeating insincere apologies while being fucked more happily than ever before.

Yuka’s flesh undulated, welcoming my cock as if she’d been eagerly awaiting it. Her pleas as she submitted to pleasure started triggering a flood of past rape memories. The memories pumped up my cock even more, causing the now-enlarged head to rub against her abdomen, the heavy shaft thudding against our combined parts.

“Oooogh… uuaah… hiiii guiya… ihhya… ihhyauugh!!”

“Haa… Yuka… So, how many times have you come…!”

“Ahii, ah, uuh… I, I can’t tell anymore… I’ve come so much, I don’t know…!!”

“So that means you came at the beginning, too…!”

“Ungh, aah, y-yes, I came…! Right from the start… it felt so good… I came so many times… higii… I cameee…!!”

Yuka writhed and moaned loudly while apologizing for lying so defiantly. It was a perfect surrender, with no room for further denial. I pinned her down on the bed on her back and tormented her with all the strength I had left.

“Aaaauugh, I’m sorry, nyah hiiii…!! Ihyaaaa… n-aah… aaaaauuu aah…!!”

“Haa… Ah… Yuka… I’m going to cum… too…!!”

“Gaaaa, guah, ihyaaaa…! Aanh… Nyaaa aaaah…!”

“…Yuka, it’s, coming… it’s coming…!!”

Byu, dobyu, gupyu, byu, byubyu—!

The body that I had repeatedly violated under Miyu’s orders, now seemed to have learned its mission of ejaculating inside a bound and humiliated Yuka, as it sent a torrent of sperm into the condom. Exhausted, I collapsed on top of Yuka, crushing her.

“…Haa… tha… Yuka, sorry…”

I managed to pull myself up and roll off her, but there was no reaction from Yuka. Now free from the need to be defiant, her mind had surrendered to the pleasure the moment she admitted defeat. She had completely spaced out as she was being fucked by me. I promised her a kiss, but it was too sneaky to do while she was sleeping.

I untied Yuka’s blindfold and released her restraints. For a while, she looked vacant with her eyes rolled back in her head. After five minutes, she calmed and fell into a peaceful slumber. Even though she had been able to rest a little when she took a bath, she had been mostly in constant motion since the amusement park. I should rest too.

Because I was so tired, I knew I’d sleep until morning, so I went to the sofa to get my phone and set an alarm. As I switched on the display, feeling the dull ache of muscle fatigue, a message appeared.

Understood. I’ll be waiting for you at home tomorrow.

It was a reply from Miyu, acknowledging that I had contacted her to say I would be home tomorrow. It was detached but strangely warm. I wanted to go home quickly and get cozy with Miyu.

I set the alarm for three hours and went to bed. Yuka was breathing softly, sleeping with an adorable face that was unimaginable from her usual sassy self. Because she was sleeping with her hair still tied up, it seemed like she’d wake up with bedhead, so I wanted to take off the hair ties. But they were tied so tightly that it seemed like they might break if I tried to remove them, so I gave up.

Then, I fell into a deep sleep until the alarm rang. Even though I thought I had only been dozing off for a few minutes after getting into bed, the loud electronic sound rang in our ears as if time had flown by. Yuka was the first one to leap up in surprise.

“Eh!? What?! Is summer vacation over already?!”

She was noisy from the moment she woke up. Maybe I woke up because of Yuka’s voice. Because Yuka had flipped up the blanket so enthusiastically, I pulled the covers back over me, gathering up the blankets that had been pushed off me.

“Good morning. Though it’s just the middle of the night.”

“Oh, good morning. When did we become a married couple?”

“We didn’t.”

It seemed reasonable that a naked man and woman lying together would be perceived as being in a relationship of some kind, but unfortunately, Yuka was just a friend, not even a fuck buddy. Neither of us was in the mood to have sex immediately after waking up, so we got out of bed to get dressed. Yuka only put on her micro bikini and camisole before diving back into bed.

“By the way, Yuka. About what happened before we went to sleep…”

I re-opened the conversation. Yuka’s face turned pale with shock. I was going to ask if she remembered our bet, but it wasn’t even necessary to confirm.

“You guys are seriously going to take responsibility for this.”

Yuka pulled the blanket around herself as if to hide her body, creating a barrier.

“You were already that way before anything happened between us. Talk to Miyu and Haruka. I’m not involved.”

“You’re not involved…! Lately, I can’t even satisfy myself unless I have a dildo…! Can that be blamed on anyone other than you?!”

“Okay, okay, it was my fault. Please stop making such explicit confessions.”

While I was curious about what girls do when they masturbate, I never know how to handle it when they bring it up.

“Well, one way or another, you’re going to atone for it. You can start by rolling your eyes back and staring at this.”

Yuka scrambled out of bed again and headed towards the sofa. Next to it on a table cluttered with the TV, karaoke equipment, and other things, her phone was propped up, blending into the mess.

“You went to the trouble of recording it?”

“Of course. What do you think of me, this Yuka-chan?”

So, the only thing thrown on the sofa had been the case. She’s good at thinking of the little details.

“You left it there for over three hours. Was there enough recording capacity?”

“Onii-san doesn’t know anything, huh? The timer that comes with the phone automatically stops it.”

“Oh.”

Yuka came back and showed me the video in which our punishment play was recorded. Just looking at the footage, it looked as if I was raping a young girl.

“With this, you have no choice but to listen to me. Forget about the bet and all that.”

Yuka triumphantly held up the phone, narrowing her eyes.

“Let’s say I don’t listen to you. What are you going to do?”

“What… Well, that…”

When I asked, Yuka didn’t fire back sharply as she usually did, and she mumbled to herself for a while. She probably just recorded it without really thinking about what she was going to do with it.

“There are so many places to send it—the school, the cops, whatever. I could even send it to Miyu.”

“What would that accomplish?”

“Well… it would cause a commotion and cause all sorts of problems, wouldn’t it?”

Yuka answered hesitantly. Well, it was true that I’d be in trouble if it were actually sent.

“Let’s say that happened. And I got into trouble with the police, or Miyu felt bad. Would that be okay with you, Yuka?”

All of Yuka’s previous threats and negotiations had a reasonable basis for considering a trade-off. But Yuka’s recent arguments seemed a little too forced. If Yuka didn’t want a lovey-dovey relationship with me, and we were just acquaintances as we were in the beginning, then this approach might have been possible, but it didn’t make sense now.

“Hmm… Well… Yeah. It doesn’t seem like it’ll be as useful as I thought. Maybe I should delete it.”

Yuka looked dejected as she manipulated the phone and deleted the video from her files. She had become docile.

“Come here.”

I took the phone from Yuka, put it on the bedside table, wrapped my arm around Yuka’s stomach, and pulled her in front of me, who was sitting on the edge of the bed, so she was sitting in the same position.

“Eh, eh, eeh, what?”

Yuka flailed her arms and legs in confusion. I gently stroked her head.

“Um, I was threatening you…? Aren’t you supposed to get mad? Do you even have emotions?”

“There was nothing to get angry about.”

Yuka was just screwing herself over on her own. There was almost no real harm done to me. As a matter of fact, there’s no reason to be angry, not because of kindness.

“Oh, okay. You’re a weirdo.”

Yuka resigned herself to being in my arms, her cheeks slightly flushed.

“I enjoy talking to Yuka like this. I’ve felt that way since the time you gave me advice. Hearing your voice cheers me up.”

Far from being angry, I was grateful to Yuka. The matter with Miyu had already been settled between the parties, and as far as it was limited to me and Yuka, I had actually been helped by Yuka more often than not.

“Besides… I like that you’re always pretending to be tough, even though there are many things you’re not good at. You seem cunning, but you’re sometimes airheaded and flustered when things don’t go as planned. Yuka, you have a certain endearing quality that stirs a man’s heart.”

“Ugh… I don’t know if I’m being praised or made fun of… It’s itchy…”

“I’m complimenting you. Let me make it clear one more time. Yuka, you’re cute, and I like you.”

I lowered the pigtails hanging over Yuka’s shoulder to the front, drew her close, and let her lean her back against me.

“That’s why I told you to stop complimenting me like that. I don’t know how to respond.”

“You were happy to be praised during the day, weren’t you?”

“Read the atmosphere.”

“Isn’t the atmosphere good?”

“That’s the problem!”

Again, with the unpredictable reactions. It’s a good thing I’m used to dealing with Miyu.

“I only want you to compliment me when I look like I want to be complimented.”

“You’re making things complicated. I can’t make a judgment unless I understand why it’s bad.”

“That’s why! It’s fine as casual conversation. I’m just saying, stop with the genuine-sounding compliments that make me take it seriously.”

I see, so that’s it. This disjointed way of speaking… I know from experience that she has a coherent thought process in her head. It seems the time has finally come to dig deeper.

“So, even if it’s what I truly feel, you’d prefer I lie and not compliment you?”

“It’s not like that… Besides, what is this? So, you seriously think I’m cute?”

I’ve been saying that all along.

“Listen, Yuka. The ‘cute’ I’m talking about isn’t just about your appearance. It’s your reactions, your gestures, everything about you is charming. Every compliment I give you is genuine.”

“Hmph… is that so…”

Yuka replies, feigning indifference. In that case, I have to give her a good, solid shock. After all, I have to fulfill the promise anyway.

“Yuka.”

I brought my face closer to the back of Yuka’s neck, and lowered my gaze to her lips. Thanks to Miyu, I’ve gotten a little used to these movements. There’s no need to worry now about being rejected by something someone yearned for.

“Just once, try accepting someone’s words honestly.”

“Eh, ah… ungh—”

I kissed Yuka. It wasn’t as passionate as she seemed to want, but our lips definitely touched, pressed firmly enough for the redness of our lips to flatten.

“Wha… eh… ha…”

Yuka stared wide-eyed, her pupils trembling. I thought she wouldn’t be so surprised, since she said she remembered what happened before she fell asleep. Contrary to my expectations, Yuka shook off my arm and retreated backwards on the bed, moving away from me.

“Yuka, be careful, you’ll fall.”

Even with my warning, Yuka continued to retreat to the edge of the bed and didn’t stop, falling backwards off the bed.

“Hey, are you okay?”

With a dramatic thump worthy of a variety show, I was worried Yuka might have gotten hurt, but she quickly got up. However, she wasn’t out of her confused state, stumbling along, using the table to support herself and walked towards the bathroom. I didn’t think I’d shocked her that much. I kind of feel bad.

I followed Yuka and opened the bathroom door. There she was, facing the mirror in front of the sink, pressing her lips with both hands.

“Are you okay?”

Even when I spoke to her, she didn’t react. Like a squirrel holding a nut, she was staring blankly, fingers pressed to her lips. When I approached and my reflection appeared in the mirror, Yuka finally realized I had followed her.

“A-Ah… ffo…!”

Yuka let out a unaffectedly cute scream like a pigeon, looking at me with tearful eyes.

“What, um, I, it’s my first, um, with a guy…”

The trembling in her eyes spread throughout her body, causing her to shake. After all that teasing and provocation, this is the reaction when it actually happens? We were just doing a blindfolded bondage play. Where did that pure reaction come from?

“Sorry if I surprised you. It was a promise, and you said you remembered what happened before sleeping.”

That’s why it was a legitimate kiss. It’s not something a guy would say when they take a girl to a love hotel, but I had no ulterior motives whatsoever.

“For now, let’s go back to the room and calm down, okay?”

I put my arm around Yuka’s shoulders and led her back to the bed. Even after sitting her on the edge, Yuka was still stunned, touching her lips repeatedly.

The first time I did “punishment sex” with Yuka, Miyu did a French kiss during the scene, so I thought Yuka would be used to it. But considering her personality, I guess she’s never had a proper kiss before.

“Um… why are you being so nice to me…?”

The question leaked from Yuka’s mouth. It was a more subdued, girlish voice than usual.

“Is it weird?”

“But, you’re just going on this date with me to repay the debt I unilaterally forced on you. Even with all my selfishness, it doesn’t feel like you’re getting tired of it at all.”

Yuka finally confessed her true feelings, looking down.

“Everyone says they like the usual me, but no one has ever wanted me. When I try to be girly, I get made fun of. When I try to cheer people up, I get teased. When I prank people, they still get mad. I, in my own way, am trying to…”

Yuka’s tone softened, trying to cloud her words. Even still, she continued to talk.

“I stopped thinking about how to get people to like me for who I used to be. I guess time will solve it as I grow up, but throwing myself away like that… feels kind of unfair.”

She worked hard to be liked by everyone when she was younger, but when it came to love, she was further away than anyone else.

The source of Yuka’s worry resonated with the quagmire Harumaki-san and I had once found ourselves in. I, too, had been lectured by Miyu once, trapped in the self-deprecating belief that I was nothing more than a creepy otaku. Because that image was what others seemed to expect of me, I’d confined myself to that negative self-perception. Even when I wanted to break free, the world around me anticipated my natural state, and I couldn’t abandon the parts of myself I had genuinely strived for.

“Miyu was the only one who truly understood my essence, right down to my core. She entrusted me with things I was good at and remained my friend, unchanging. …Though, she never directed as much attention towards me as you do, Onii-san. But I was happy.”

Miyu is kind, mature beyond her years, and because of that, she overly acknowledged the humanity at Yuka’s core. That eventually made Yuka fixate on Miyu, causing a belated crush to bloom.

Just because the root cause lay there, it didn’t mean Miyu was at fault in any way. If Miyu hadn’t shut herself off emotionally during that period, she probably could have easily guided Yuka into adulthood without her becoming so twisted. Though now, Miyu is no longer emotionally constrained. But after their long history together, now that Miyu has become an object of reverence for Yuka, Miyu can no longer be the ‘someone she wants to love her back.’

That’s why I just need to fill in that missing piece. In my relationship with Yuka so far, simply continuing to convey the feelings of ‘I like you,’ born from my true heart, was enough. Even if the ‘selfish, mischievous girl’ persona, solidified by the expectations of those around her within Yuka, tried to deny the goodwill of others. Until Yuka herself could love who she is.

Yuka expecting me to act like a boyfriend, yet recoiling and blushing crimson whenever I treated her like a woman—that was the answer all along.

“I’ve had my own thoughts about you too, Yuka. I’m not as perceptive as Miyu, and we’ve both done our fair share of questionable things to each other. But knowing you as I do now, I genuinely love you, Yuka. I just want you to believe that.”

From behind, I couldn’t clearly see Yuka’s face. But at my words, she closed her eyes for a long moment, lost in thought. Then, gently, she placed her hand on my arm.

“…Yeah. Thank you.”

Yuka’s reply was short. Then, she slipped out of my grasp, stood up, and flashed a smile as if she’d finally broken free, a refreshing grin.

“Onii-san, you’re a good man, you know? I acknowledge that.”

Yuka, saying those words, was radiant, composed, and somehow embodied the ideal girl everyone dreams of. At that unexpectedly gentle reaction, an indescribable haze of unease began to gather in my chest.

Yuka’s movements as she gathered the scattered belongings on the sofa held a maturity that unconsciously mirrored Miyu’s, a trait ingrained from years spent together.

“Um, did my feelings get through to you?”

“Of course. You’ve been saying you liked me since the amusement park. I was even thinking, like, ‘Ehh—are we really going to start dating—?'”

Yuka quipped, putting the cover back on her phone that had been lying on the bed. Her words lacked the usual sharp edge that used to resonate within me.

“If they got through, that’s good.”

As I spoke, a sense of urgency grew in my heart. I felt like I’d betrayed something Yuka had been expecting. Maybe that was the trigger that made Yuka choose to become an adult at that moment when she thanked me. It might have been the right path for Yuka, but I felt a profound emptiness.

Surely, the worry was still there, sealed away deep within Yuka’s heart. If I couldn’t change the flow here, I might never be able to resolve it for her.

“Don’t you want to take a shower? We both broke a sweat, and you’ve had your hair tied up the whole time, right?”

“Yeah, you’re right. I can’t sleep feeling all sticky like this.”

Yuka took two bath towels from the hanger and handed one to me.

“What do you want to do? Should I go first? Or… shower together?”

Yuka’s casual question struck a chord within me. The old Yuka would have unequivocally chosen ‘shower together.’ Has she decided to be considerate of Miyu now, since there’s no need to be selfish anymore?

“Either way is fine, whether we shower together or you go first.”

Leaving the options open, a response close to a deferral.

“Hmm.”

Yuka thought, letting down her tied-up hair. Watching her, my thoughts momentarily veered off course.

“…Straight hair… it really changes your impression.”

“Everyone says that.”

The hair that had been tied up on both sides was now released, and as her hair extended longer than I’d imagined, her usual mischievous cat-like eyes looked unexpectedly delicate.

“Your hair down… it’s nice too. Really nice.”

I only meant to offer a simple compliment. But Yuka’s mouth twisted into a frown as she glared at me.

“It’s because Miyu has straight hair, isn’t it?”

“Eh, ah, no, that’s not it…! Off-mode Yuka is cute too, and of course, I love twin-tails Yuka too, both are compliments…!”

I frantically scrambled to explain myself. Seeing me like that, Yuka chuckled softly.

“It’s about your girlfriend, you don’t have to deny it so desperately. You’re still a weirdo, you know?”

Yuka laughed brightly again, and seeing that, I suddenly realized. The reason I’d rushed to make excuses was because I felt that if I didn’t, I’d lose my chance to touch upon Yuka’s worries. But trying to solve someone’s problems when they hadn’t even asked me to was just presumptuous. I’d been so fixated on fulfilling Miyu’s wish, but it was too dismissive of Yuka’s feelings. Originally, I was just told to interact with her naturally, and knowing Miyu, she would probably handle things smoothly no matter the outcome.

“I wanted to compliment Yuka, as Yuka.”

Discarding my clumsy thoughts and relaxing, those words just came out. I wasn’t supposed to be the kind of guy who says such cheesy things, but somehow, while dealing with Yuka, I’d gotten completely used to it.

“Onii-san, you’ve become quite the charmer, haven’t you? Your ‘older sister’ is pleased.”

“Come to think of it, you’ve known me since I was a total loser otaku, right, Yuka?”

“Totally, totally. You were such a hopeless guy back then, but you’ve really grown up, haven’t you?”

“Why are you always looking down on me…?”

Still, it makes me happy that she knows what I was like back then and still admires me now. I wonder if Yuka feels grateful for someone like me, from her opposite perspective? If so, that makes me happy too.

“Hey. Before we shower… want to talk a little more?”

I sat on the edge of the bed and patted the bed beside me, inviting her to sit next to me this time.

“Fine, whatever. I’m in the mood too, so I’ll keep you company.”

Yuka grinned mischievously as she sat down beside me. It seems like we’re getting back to our usual distance.

“You really are a good person, Yuka. No wonder Miyu chose you as a friend. Haruka, too, I bet if they got along, she’d see all the good things about you, just like I do.”

“Nah, that woman is pure evil to the core. If this were a movie, she’d be the mad scientist who betrays the boss at the end and becomes the real final boss.”

Surely not. I admit she has the potential for it, though.

“You still don’t know Haruka’s true self, Yuka. You two were like rivals in love. I’d be happy if the three of us could get along in the future.”

“I hope so, but… I don’t plan on becoming distant with either of you.”

I wonder if Yuka will go to the same high school as Miyu? It seems she’s going to a public school that even I could get into, let alone a prestigious one like Miyu. Though, I even doubt if Yuka’s grades are good enough for that level. From what she said during our first ‘punishment’ session, her academic abilities are apparently disastrous.

“Speaking of which, you said you pranked Miyu because she wouldn’t let you copy her homework, but was that really true? Now that I think about it, that feels like another lie you just blurted out.”

I already know from our ‘punishment play’ that Yuka cries like a child when she’s cornered, but with her cunning, she probably wouldn’t have gotten Miyu angry over something as trivial as homework.

“You finally noticed, huh?”

Yuka snapped her fingers again, the sound just a faint click.

“Two percent of it was a lie.”

“Don’t tell me eighty percent of it was true!”

“I just… don’t feel motivated to study, you know? And if I could stir up Miyu’s emotions, any reason was fine. That’s how I was back then.”

It must have been a real nuisance for Miyu, but if they were interacting like that, maybe Miyu was prepared for it.

“You really do everything in such a flamboyant way, Yuka. Even that lingerie… where did you even get it?”

“Online shopping. I’m over 160cm tall, you know, there’s a lot I can buy.”

Yuka smoothed her straightened hair with her hand and added, “I am a lady’s body, after all.” Surrounded by those huge breasts every day, maybe I’ve become desensitized, but for someone who prefers smaller chests, Yuka must be irresistible.

“Flashy clothes like that really suit you, Yuka.”

The low-cut camisole revealed the string lingerie, barely concealing her nipples. The short camisole only reached her waist, and if you lowered your gaze just a little, you could peek at the deep groove where the thong was digging into her crotch.

“It’s so erotic, no matter how many times I look.”

“Right? Right? Making you want to go for round two?”

“You’re getting cocky again. You should just take compliments gracefully at times like this.”

“I want to be praised right now. Until morning, I’m your girl, so learn how to treat me properly already.”

Yuka puffed herself up, acting all high and mighty, and she’s right, she did say this date was until morning. She still wants to be with me like this, huh? It’s much better than ending things on that slightly distant note from before.

“I was able to become close with Miyu thanks to you, Yuka. You’ve helped me out so many times. I’m grateful.”

“Heh heh. Once I give the go-ahead, it’s too late to praise me.”

“Even so, I want to make sure you know. No matter how much I owed you, I wouldn’t have gone on this date if it wasn’t with you.”

When I said that, Yuka tilted her head slightly and looked up at me with expectant eyes.

“Really?”

“Really.”

“Then let’s have raw sex.”

“Absolutely not.”

“Mooou!”

I thought we had returned to our original relationship, but she had wound it back more than necessary. Miyu told me to let her do as she pleases, but I have no intention of having raw sex with anyone other than Miyu. Yuka thrashed around on the bed like a child for a while, then took a deep breath.

“Haaah… fun.”

Sitting up, Yuka stared at me. It was the purest gaze I had ever seen.

“You know, Onii-san…”

Yuka opened her mouth, her eyes locked on mine. It was the same gaze, the same tone, as when Miyu had revealed her true feelings that day.

“Actually, I knew all along… that this was Miyu’s plan.”

The feelings that Yuka had been trying so hard to shrug off… those were the worries that had remained with her until the end, Yuka’s sorrow.

“It’s weird to go on a date like this when you already have a girlfriend, no matter how much you owe someone. And you being so nice to me, praising me so much… I knew Miyu told you to do it. I knew it in my head, or at least I thought I did…”

Her voice gradually became hoarse. Full of breath, as if squeezing the words from her throat, a voice that made my chest ache.

“Being praised by Onii-san… it made me so unbelievably happy. No matter how many times I denied it, even knowing it was Miyu’s orders, for some reason, when I heard your voice, my chest tingled, and my excitement went up. And then, I… maybe… I started fantasizing about something impossible…”

At the end of confessing her feelings, Yuka looked away and clenched her fist tightly.

“I kept thinking all these stupid things like, what if this misunderstanding was real…?”

The reason Yuka didn’t believe my words until the very end was because I had Miyu, a sister with almost supernatural insight.

That’s why I had to realize Yuka’s worries, I had to resolve them. I’m not a liar, so if I had been acting on Miyu’s orders, I would have confessed it even if I hadn’t been asked. But now, I can say it with confidence.

“Listen to me, Yuka. I don’t know what you’ll think of what I’m about to say, and there’s no proof that I’m telling the truth, but…”

I’m sure she’ll understand. Yuka already knew it instinctively.

“I want you to know… all Miyu told me was that you were worried about something and that it was okay to go along with whatever you wanted to do. Beyond that, there were no instructions, nothing.”

As I spoke, large drops of tears were falling onto the knees of Yuka, who was looking down and hiding her face with her hair. The sound of her sniffling grew louder, and I don’t know if she could hear my voice, but I had to tell her these words.

“The feelings I’ve conveyed to you until today… they’re all from my true heart.”

It was a phrase I had repeated many times before. But to Yuka, it must have conveyed a completely different meaning than before.

“Uuu… uuu…”

Yuka sobbed and continued to cry.

“Uuuuuuu…!!”

Eventually, that sobbing turned into a earth-shattering groan, and Yuka literally bared her fangs at me.

“Eh? What’s… what’s wrong?!”

“You bastard—!! Making a girl so happy—!! What am I supposed to do when a guy with a girlfriend says something like that to me—!!”

Yuka jumped on top of me, and it hurt quite a bit because she came at me with a lot of force, but what she was saying was so valid that I couldn’t do anything about it.

“My heart is so full of joy that I’m somehow getting angry!”

“I don’t think your heart is full of joy, but…”

“Whatever! Jeez…”

Yuka, who had pushed me down, wiped her tears away with my clothes without any hesitation, then rolled off the bed and lay down. I also released my tension and lay down, staring at the ceiling.

“By the way… are you really sure it wasn’t Miyu’s orders?”

“It depends on what you consider an order, but at least, she didn’t tell me what to do or what to say. Oh, Haruka did tell me that you’ve been rejected a lot.”

If I hadn’t overheard that, I probably would’ve stumbled all over myself, asking stupid questions when Yuka told me about the guy who dumped her. Haruka really helped me out a lot back then, too.

“That bitch… what does she think personal information is, some kind of toy…?”

Yuka punctuated her words with a furious right hook into the air, then let her arm drop with a thump.

“Well, at least I got Onii-san to fall for me, so it all worked out!”

Yuka latched onto my arm, radiating good cheer. Her ability to switch gears was still going strong, huh? Yuka was going to be friends with Miyu, and if they could get along without any drama, that was the best-case scenario. Maybe Miyu had a similar ending in mind for Yamamoto-san…

“H-Hey, Onii-san…”

Her voice was tight, her expression strained, as Yuka gripped my arm with surprising force. Her lips slowly pursed, forming a face like a hyottoko mask eating something intensely sour.

“I.. I li… I like…”

In broken katakotoba that would make a foreigner blush, Yuka eked out the word between her teeth, like she was exhaling her very soul.

“Huh? What’s that?”

I was confused, both by what she’d said and by her sudden, bizarre behavior. Yuka’s eyebrows shot up at my reaction, and her grip on my arm tightened painfully.

“We had a deal, didn’t we?! If I want an icha-rabu, I have to say ‘I like you’!”

“Ah, that’s right. I forgot. Well, yeah. Thanks. I’m happy to hear that.”

“You suggested it! Why are you reacting like that?!”

Yuka pummeled my shoulder with light, irritated blows, then, growing bored, she cleared her throat with a “Kohon!” and composed herself.

“I like you, Onii-san. …Not that it means anything. I just wanted to let you know that I, as a woman, have fallen for you.”

Yuka, who was just inches away from me on the bed, delivered her flat confession with such a serious face that it barely registered. I didn’t know what kind of mental gymnastics she’d performed to reach this point, but I figured Yuka would compartmentalize it just fine.

“Which means, of course, we’re doing ecchi until morning, right?!”

Just like that, Yuka sat up, snatched a condom, and practically threw it at me.

“Today’s the last time, remember? I’ll indulge you as much as I can.”

“Oh, and I don’t think you’ve forgotten… the real last hurrah is that deluxe jumbo parfait after we leave the hotel. Then I’m going straight to cram school.”

“Hold up, hold up. This amusement park and love hotel date is supposed to pay off my 500-point debt, right?”

Besides, going to cram school? What the hell? She doesn’t even have her textbooks, let alone any stationery.

“It works out like this.”

Yuka reopened the notepad app on her phone and started assigning points to the ecchi’s pleasantness and the happiness she felt from my compliments – she was clearly making it up as she went along, but for the sake of balancing the scales – and, after tapping away for a while, she’d miraculously canceled out the 500-point debt, leaving exactly enough for me to buy her that deluxe jumbo parfait.

“See? It’s all settled!”

“How are we calculating the sex we’re about to have?”

“I fulfilled my promise to confess, and Onii-san is going to initiate some lovey-dovey sex all on his own, so there’s no debt involved, right?”

“I can’t argue with that logic.”

Maybe Yuka was smarter than I thought. Even someone who was just cunning and street-smart couldn’t pull off this kind of thing if they were simply incapable of studying. Could this be another facet of Miyu’s discerning taste in friends?

“Alright, let’s get this second round started! This little guy’s gonna down his second shot!”

Yuka held up another one of those energy drinks and popped the tops off both bottles. As a man, I couldn’t back down.

“We’re starting right now.”

I downed the bottle in one gulp and yanked off my pants. Then, I laid Yuka, who’d also drained her energy drink, down on the bed and unfastened the drawstring of her panties.

“Are you going to leave my top on?”

“You look so sexy in that outfit.”

“You really liked it that much, huh? Mufufu. You dirty pervert.”

Yuka gazed up at me with a goofy, unguarded grin. Her nether regions were nicely lubricated and relaxed, which, unless I was completely misreading the situation, had been happening since she confessed.

As we positioned ourselves for missionary, my member naturally pointed skyward. It wasn’t just about anatomy; I was genuinely turned on by how cute Yuka was. After I slipped on a condom and pressed close to her, Yuka reached out both hands, and I laced my fingers through hers as I entered her.

“Ngh… Ah…”

I wasn’t going to make her swallow my come, nor was I going to punish her with rough play. So, Yuka probably wouldn’t orgasm during this sex, and I probably wouldn’t ejaculate either. Even so, there was a gentle joy in my heart, just from being connected to Yuka like this.

“Does it feel good, Yuka?”

“Yeah. Doing sex with you feels good, Onii-san.”

“Is it satisfying?”

“I don’t know. I’m not sure… It’s like—”

Yuka locked eyes with me, her cheeks flushed with a delicate crimson, and this time, she didn’t try to hide her bashful feelings, offering me a dazzling, innocent smile.

“I’m… happy!”

Yuka, beaming with pure joy, and I spent that night lost in simple sweetness, falling asleep with her long before the sun rose.
