My Little Sister Is the Best F*p Material

Volume 4 Chapter 5: The Battle of the Bad Liars

I woke up on the sofa to the sound of a mosquito-like buzzing. Annoyed, I waved my hand, but the persistent vibration continued to irritate me. As I sat up, my head spun, and a sharp pain tore from the insides of my thighs to my bladder.

“Ouch…!”

I’d ejaculated too much. Maybe I should see a urologist.

“Huh…?”

The noise stopped as soon as I woke up. Had the bug flown away?

In my hazy consciousness, I became aware of a hard object pressing against my hand. The source of the vibration from earlier seemed to be my smartphone. I hadn’t set an alarm, but when I turned it on, the display showed three missed calls from Yamamoto-san, along with five unread messages.

“……Eh?”

I was supposed to be at Yamamoto-san’s house at eleven. How long had I been asleep? It felt like I’d only dozed off for a moment. Glancing at the time, my heart began to race. It was already past one.

“Shit—!!”

I jumped off the sofa and hurriedly called Yamamoto-san. My pounding heart echoed in my ears as I held the phone, amplifying my anxiety.

After fixing my clothes and hair, I waited through seven rings. Terrified she’d hate me, I frantically prepared to leave, and finally, Yamamoto-san answered.

“Sorry!!”

I blurted out my apology before she could say anything.

*”Oh, hey. Are you okay?”*

To my surprise, Yamamoto-san sounded completely unfazed. Typical of her, I guess.

“I’ll be there right away! Just give me ten minutes!”

*”Are you sure you’re okay, Sotomichi-kun? If you have other plans, we can reschedule…”*

“I’m fine!”

*”Alright then, I’ll be waiting.”*

I locked the door and rushed out. Yamamoto-san had already given me her apartment number, so she’d let me in once I arrived at the entrance.

Under the scorching sun, the breeze from my bike made it slightly cooler than walking. I parked my bike at the apartment building and dashed to the entrance. The air conditioning inside was already on, and despite my hurried breathing, I didn’t break a sweat.

Yamamoto-san opened the automatic door for me, and I stepped into the elevator. Her apartment was on the eighth floor. Standing outside her door, I took a moment to steady my breathing before pressing the intercom. She answered immediately.

“Welcome. Come in, it’s hot out.”

“Th-thanks for having me.”

Her apartment was a typical vertical layout, with high-quality finishes and a spacious kitchen, exuding luxury for a single person’s home.

As soon as I closed the door behind me, Yamamoto-san turned around and pressed me against it with her breasts. She wore a thin T-shirt, so sheer that her bra was visible, and her ample bosom pushed against me with soft, yielding pressure.

“Now, care to explain what’s going on?”

In the entryway of her bachelorette pad, I was cornered, still wearing my shoes. Yamamoto-san’s large breasts left no room to move.

“I’m so sorry! I overslept…”

It was unusual to sleep until midday, but I wasn’t lying, so there was no risk of slipping up.

“You were asleep until just now?”

“Yeah, I’ve been exhausted lately. My apologies.”

It was true. If Miyu hadn’t made me ejaculate so much, I’d have been here on time, skipping with energy.

…No, I know. I’m the one who initiated half of those encounters, so Miyu isn’t to blame. I don’t want to fault her. But when my sister invites me to sleep with her, it’s only natural for me to get the wrong idea. I can’t take all the blame. Miyu herself, despite saying we need to distance ourselves, has been actively seeking physical contact with me until this morning, making it hard for her to let me go to Yamamoto-san’s.

“Sotomichi-kun, you really don’t seem that interested in me. I’ve never been treated so negligently before.”

Yamamoto-san matched my gaze, pressing her breasts against me insistently.

“That’s not true. I was really looking forward to this, but things came up.”

“What kind of things?”

Oh no, I’ve already slipped up. Damn it, what should I say?

“Well, it’s… hard to explain.”

“Hard to explain? Is there something worse than what’s already happened?”

Of course, there is—a massive bombshell. I can’t possibly tell her I’ve already been intimate with my own sister.

“I was so excited last night that I couldn’t sleep…”

“You couldn’t sleep?”

“Yeah, that’s it.”

Normally, admitting you couldn’t sleep because you were excited about a sex date would be a major turn-off.

“Oh, you poor thing.”

Yamamoto-san smirked and released me. That’s just how she is—she doesn’t get angry easily and always interprets things positively. Someone as beautiful as her has probably dealt with men’s desires her entire life. Yet, she never reacts cynically to compliments.

But knowing I’m betraying her pure heart fills me with guilt, making it hard to breathe. If only Miyu weren’t involved, I’d come clean about everything.

“Then, Sotomichi-kun, you’re ready, right?”

Yamamoto-san casually wrapped her arm around my waist, making her intentions clear.

“Uh, yeah.”

Here I was, in the ideal scenario for a man—about to get an instant blowjob. Yamamoto-san had been looking forward to this, after all.

She’s always been frustrated because her partners climax too quickly, leaving her unsatisfied since middle school. Now, with me—her first real chance at proper sex—she must be incredibly pent-up, especially after I showed up late.

Yamamoto-san hooked her fingers into my pants, ready to pull them down, when I remembered Miyu’s warning from earlier:

—Make sure to shower before having sex with Yamamoto-san. Otherwise, you’ll get caught.

“Wait! Stop!”

I grabbed Yamamoto-san’s hand, halting her. In my rush to leave, I’d forgotten to shower. My body still carried the scent of the semen I’d released twice this morning, Miyu’s saliva from licking it up, and her strong hair treatment fragrance. While none of this definitively proved I’d been with Miyu, I wasn’t confident I could handle the interrogation.

“What’s wrong?”

“I need to take a shower. I’m sweaty.”

As a man, it would feel better to just let her go ahead, but this time, I couldn’t. I had to wash away any chance of Miyu and I being exposed.

“That much? Your shirt and pants don’t seem wet. I don’t mind a little sweat, you know?”

Yamamoto-san checked that the waistband of my pants wasn’t damp and tilted her head in confusion.

This was an oversight. I’d tried so hard not to sweat to look good for Yamamoto-san, and it backfired. If I’d arrived drenched in sweat, she would’ve suggested a shower herself.

“I… haven’t taken a bath since yesterday! I’m probably really smelly.”

I hated saying this, but I had no choice.

“Hmm…”

Yamamoto-san studied me with a skeptical gaze.

“It sounds like a lie.”

I’d piled on too many clumsy lies. I’d rushed out without thinking. If I’d paused to call her first, I could’ve at least showered.

“You usually take proper baths, right? Miyu-chan wouldn’t let you stink, would she?”

“Yeah, well.”

“You knew you were going to have sex with me today, right? So, if you deliberately skipped a bath to make me lick you, I’d understand. But asking for a shower now? What’s that about?”

Her question caught me off guard. I’d expected her to ask if I knew we were having sex today, but I never thought I’d struggle to explain my lies this much.

I couldn’t take back what I’d said. I needed new information to counter.

“I… had an offline meetup! I was playing a game I had to finish overnight, and I got too into it.”

“So, you were lying about not being able to sleep because you were excited to see me?”

Ouch—my heart hurt. I didn’t want to hurt Yamamoto-san, but I couldn’t backtrack now.

“I’m sorry! Really sorry! The meetup was scheduled first! I tried to rest to recover some energy, and it was past noon before I knew it. I meant to take a bath, but I didn’t have time.”

It connected smoothly, with no inconsistencies in the context.

“That’s a lie.”

“Eh, uh…”

She saw through it instantly. Yamamoto-san’s eyes grew sharper. Usually, she looks so carefree, but when she gets serious, I can’t lie to her.

“When you date as many men as I have, you start to understand their true nature, whether you like it or not.”

Yamamoto-san has far better social skills than me. With her extensive dating history, wide social circle, and intelligence, I was no match for her.

“Sotomichi-kun, you’re speaking the same way you did when you confided in me about your troubles. And no matter how busy you are, you wouldn’t ditch our plans for a game, right?”

Her words hit home. Since my troubles involved Miyu, my way of hiding it was the same.

The tension between us was palpable. As I broke into a cold sweat, Yamamoto-san’s expression brightened.

“Well then, let’s make the most effective request to a timid, kind boy like you who can’t keep up his lies.”

Still crouched by my waist, she softened her gaze invitingly.

“Tell me the truth.”

Her innocent demand for honesty left me no choice but to comply.

“I overslept because I was tired, and I was excited for today—that’s true.”

“Uh-huh.”

“The meetup is real, but I didn’t game late, and it’s unrelated to this.”

“I figured.”

“I took a bath last night… but I still want a shower now, and that’s the truth…”

I’d revealed everything. Even with this much information, she wouldn’t connect it to Miyu.

“So, you’re tired and need to wash something off. Would you be troubled if I undressed you?”

“I’d be troubled, but…”

Maybe I’d overthought this. I panicked and lied because of Miyu’s warning, but there’s no way she’d figure it out just from the smell.

“Well… it might smell a bit like… semen…”

“Um, Sotomichi-kun?”

Yamamoto-san looked exasperated. Ah, Miyu often gave me that look too.

“Did you… finish yourself off after that?”

“Yes…”

I’d ejaculated far beyond “finishing myself off.” Though it was with my sister.

“I see. From our past encounters, I knew you had a high sex drive. If I made you hold back too much, I’m sorry… But couldn’t you last a day?”

Her voice, scolding yet gentle, made me feel pathetic as a man. Despite an hour-long fellatio session heightening my desires, I’d already ejaculated from a footjob with Yamamoto-san earlier. She couldn’t imagine I’d fail to abstain for even a day.

Thanks to Miyu, my sex drive had skyrocketed, and I couldn’t stop myself from ejaculating whenever we were intimate. My penis had grown larger, and my libido had surged since Miyu caught me masturbating to sister porn. Where does my responsibility begin?

“You slept until noon because you were… doing it in the morning?”

“……Yes.”

“Ugh. Why couldn’t you wait until you got here? This deserves punishment.”

“I agree…”

This was bad. Being punished by Yamamoto-san in my already drained state? I’d have to prepare for a bellyful of cum.

“No matter how much I ask, there are limits. Today, thinking about Miyu-chan is forbidden.”

“That’ll kill me!”

“Nope. I’m going to treat you like a toy.”

Yamamoto-san forcefully pulled down my pants. My still-soft penis hung limply, and she pinched it, squeezing gently before bringing it to her nose to sniff.

“It really smells like semen. You can only ejaculate using Miyu-chan as your fantasy, right? Did you finish with her before coming to me? Do you even want to separate from your sister?”

“I’m sorry…”

I didn’t want to ejaculate this morning. I overslept because of my second release, which I asked for myself.

Was I really at fault?

“But it smells kind of nice too.”

“Nice? Why?”

I took two showers yesterday after ejaculating in my pants. Maybe some body wash scent lingered.

“I think I know this smell… *muffled*”

“Oh, ahh…!”

My still-small penis was suddenly swallowed whole by Yamamoto-san’s mouth. The unexpected pleasure made me jerk back, hitting the door. My foreskin-covered penis felt like it would melt inside her hot mouth.

“Ngu… mmm… chu… pah… nh…”

Yamamoto-san rolled her tongue around my penis for a moment before releasing it.

“Mmm…”

And then, she glared at me again.

“Maybe you should take a shower after all.”

“Huh!? Was it that bad!? Sorry… I usually don’t smell like this…!”

“It’s fine. Go ahead.”

I pulled my pants back up and entered the room. Yamamoto-san quickly showed me to the bathroom and instructed me where to place my clothes.

“Do you use toner or lotion?”

“I only moisturize at night, so if I end up showering again, I’ll use it then.”

“What about hand cream?”

“I don’t use that. Never have.”

I hate the sticky feeling on my hands. It’s annoying when using my phone. Miyu applies it after every dish she washes, but I touch keyboards and other things, so I don’t want to get them greasy.

“I’ll leave a towel for you. Use as much hot water and body soap as you like. And… this.”

Yamamoto-san pointed to a laundry basket in the corner, its lid closed to hide the contents.

“Put your clothes on the lid of the laundry basket. If you rummage through my underwear, even I’ll get mad.”

“I get it…!”

Do I really lack that much trust when it comes to underwear? She said she understands men, but surely she doesn’t see through what happened this morning. It was an accident, with no ill intent. I’ll strongly affirm that, just in case.

After Yamamoto-san left the changing room, I undressed. It was my first time being naked in someone else’s home. It felt like I was exposing myself outdoors, making me nervous.

The bathroom was modern and clean, likely in a newly built building. Cleansing oil and hairbands were neatly arranged in cases, making me realize I was truly in a girl’s home.

I washed my body thoroughly, especially my neck, which still smelled of Miyu. Somehow, I’d made it through. If she’d asked one more question, I would’ve confessed. Now, all I had to do was successfully have sex with Yamamoto-san. My lower body was exhausted, but if I got through today, future encounters would be enjoyable.

After showering, I dried off, rubbed key areas to ensure no scent remained, and checked myself.

“Alright. No issues.”

I dressed and entered the living room. Yamamoto-san’s room was minimalist, with colorful accents, yet cohesive in its white-themed decor. Two cushions lay under the table, and she sat on one, her legs tucked under her.

A bad feeling crept over me. That posture reminded me of when Miyu was troubled about her chest size.

“Thanks for the shower. I feel refreshed.”

“You’re welcome. Sit here.”

I sat on the cushion next to her, feeling slightly uncomfortable without a chair.

“Sotomichi-kun…”

She began formally, signaling something serious was coming.

“I know I tempted you, and that was wrong…”

Her words were immediately unsettling.

Was I about to be scolded? For what?

“You’re cheating, aren’t you?”

I was stunned.

“Huh? Uh, well…”

Where did “cheating” come from? Cheating requires a partner, and I don’t have a girlfriend.

“Wait… Are we… like… dating?”

Could this be a romantic relationship? We were about to have sex. If this wasn’t dating, then we were friends with benefits. I’d rather not think of Yamamoto-san that way, but if we were already dating, I wish she’d made it clearer.

“No, not that. You have a girlfriend, right? You had sex with her this morning, which is why you were late?”

Yamamoto-san questioned me with certainty. She thought I had a girlfriend. At the door, she’d smelled another woman’s scent but didn’t realize it was Miyu. Of course—no one would assume their sex partner was their sister.

“I’ve struggled with this condition for so long… I do want to have sex with you, and our last time was fun.”

Yamamoto-san’s expression was conflicted, yet she smiled shyly. Her words made me happy.

“But I don’t want to make anyone unhappy for my own happiness. I’m aware of my appeal, and I was the one who tempted you first, so I’m not angry. I’ll even apologize with you. Please, be honest.”

Yamamoto-san looked at me seriously.

This was a tough spot. To clear up her misunderstanding, I’d have to tell her about Miyu. If I asked Miyu, she might even agree.

But would Yamamoto-san believe me if I revealed my partner was my sister? Wouldn’t that just complicate things further?

What should I do? How could I get through this without hurting either of them?

“Did something happen while I was showering!? I thought I explained at the door—I didn’t want you to smell me because I’d just come!”

She misunderstood me as having a girlfriend. I had to correct that. Yamamoto-san was just suspicious of my behavior when I arrived.

“At that point, like I said, I think I understand men. I thought you didn’t have a girlfriend and wouldn’t cheat. That’s why we went on a date yesterday.”

“But the only evidence of cheating is that I didn’t want you to smell me, right? Even Yamamoto-san’s guesses can be wrong sometimes.”

In reality, she was half-right. It was strange to do such erotic things without being lovers, so her guess was almost correct.

“Even so, your reaction was too suspicious. I don’t want to make anyone unhappy because of me.”

If I’d lied better, I could’ve convinced her. But my panic gave me away.

“I’m not mad, and I won’t be. I think you’re a great person, and that won’t change.”

Yamamoto-san held my hands in hers and looked into my eyes. Her gaze was clear, like staring into a starry sky.

“It’s okay. It’s natural. You’re having trouble with your girlfriend, and you came to me to solve that, right? I know you’ve been holding back until now. So, please, Sotomichi-kun, show me what’s really here.”

She placed her hand on my chest and slowly moved her lips.

Her radiant, flawless skin. Her eyes, a perfect blend of sharpness and adorability. The pinnacle of unmatched intellect. How could I possibly face this goddess?

“F-for example…”

I spoke while maintaining eye contact. My heartbeat, beneath her hand on my chest, must have been audible. If I showed any more agitation, I couldn’t hide it.

“If it’s true I don’t have a girlfriend, how can I prove that ‘non-existence’?”

The so-called “devil’s proof.” Being accused of something that doesn’t exist turns imagination into a basis for possibility.

Yamamoto-san believes I have a girlfriend and, to solve my issue of only being able to ejaculate using my sister as a fantasy, reluctantly decided to have sex with her. But there’s no concrete evidence. So, the weak point remains in her reasoning.

“Then, let me ask you something.”

Yamamoto-san’s eyes sharpened. She was observing me.

Here it comes—the question that would shatter my lie.

Predict it. Any question. Don’t show agitation.

“When I was… giving you oral earlier…”

Yamamoto-san removed her hand from mine.

Then, over my pants, she pressed her fingers against my penis, which she’d briefly taken into her mouth earlier.

“Why was there hand cream on it?”

When asked, I was surprisingly calm. I hadn’t known there was hand cream on my penis.

Yamamoto-san had mentioned my penis smelled like semen but also had a nice scent. If there was hand cream, that explained the pleasant smell.

But I’ve never used hand cream.

“Hah—!!”

The moment I realized, I gasped. My heart raced, and despair crawled up from my stomach.

Three conclusions linked together—a triple realization. The impact of this unprecedented insight left me stunned.

I was checkmated from the start. Before the shower, Yamamoto-san asked if I used hand cream, and I said I never had. That question was to confirm I hadn’t touched myself before coming.

The hand cream on my penis was from Miyu, who’d used it just before leaving. It hadn’t dried completely, melted from the heat of my erection, and rubbed in.

That’s why Miyu told me to shower. She knew Yamamoto-san would notice if I’d been with another woman.

“How can you be sure it’s hand cream?”

“It’s useless now. You know it’s undeniable, right?”

Yamamoto-san pressed her finger to my lips. The scent wasn’t the issue—my agitation was the biggest giveaway.

“Why go to such lengths to hide it?”

She was genuinely puzzled. Cornered like this, anyone would confess. She promised to forgive everything and end it amicably. In this situation, no matter how stubborn I was, Yamamoto-san, suspecting me of cheating, wouldn’t have sex with me. After all, she proposed today’s encounter. I had no reason to cling to having sex, from her perspective.

“Well… because… there are things I can’t talk about…”

I wanted to tell her the truth. Not partial truths, but everything about me.

“Things you can’t talk about? Like what we discussed after the closing ceremony—needing Miyu-chan as a fantasy to ejaculate…”

At that point, Yamamoto-san froze.

I couldn’t hide it anymore. She’d reached the only conclusion.

No, she’d known from the start. All the clues pointed to it, but she’d dismissed the most likely answer as impossible.

“Huh…!?”

Her eyes widened, and she pulled back. Her mind must be racing, logic clashing with ethics.

“Whaaaaaat!?”

She stumbled back to the wall.

No wonder she was shocked. My own sister handling my sexual needs?

“Huh? Huh? What? What’s going on?”

Yamamoto-san was confused, questioning no one in particular. I’d never seen her so flustered.

“There are circumstances. And to clarify, we haven’t had sex. It’s not as deep a relationship as you think.”

“Oh, right… right…”

Yamamoto-san abandoned her logical constructs, built through elimination, to reach this answer.

“Miyu-chan…?”

Yes, it could only be Miyu. My suspicious behavior and our interactions all pointed to her.

“Sorry.”

The first words out of my mouth after being exposed were an apology. I’m not sure who I was apologizing to.

“Is this an apology for lying to me?”

“Partly, but also because this situation isn’t pleasant for you.”

Men might envy me, but incest is universally condemned.

“I don’t mind what you do with Miyu-chan… but…”

Yamamoto-san hesitated.

“Isn’t this still cheating?”

Ah, that’s what bothered her.

“It’s not cheating. Miyu and I aren’t dating.”

“But you and Miyu-chan are in love, right?”

“I might be, but I don’t think Miyu is.”

“Why not!?”

Why not?

Why…?

It’s been a mystery since the first time.

She says she loves me as a brother but not as a man.

“I don’t know.”

“Hmm. Maybe you’re just dense, and she actually loves you.”

“I wish that were true. She’s been telling me to get a girlfriend forever.”

If Miyu loved me, we’d have no problems. We’d be together every day, definitely having sex.

“Was the shopping mall incident related to this?”

“Yes. I consulted her because I couldn’t get aroused by anyone but her.”

Miyu had Yamamoto-san arouse me in the fitting room, hoping I’d develop feelings for someone else and become normal. She introduced me to Yamamoto-san because she saw my obsession with her as a serious issue.

“Miyu-chan knew, huh. I thought it was strange. She acted like it was a secret, yet she asked me, her Big Brother’s classmate, to help with your arousal issues.”

Miyu’s actions were always extreme, desensitizing me. The fitting room incident was too much. If it weren’t for Yamamoto-san, it would’ve fallen apart sooner. Miyu must have known Yamamoto-san well enough to take that risk.

“Sotomichi-kun…”

Once the conversation settled, Yamamoto-san sat beside me again.

“If you keep having intimate situations with Miyu-chan, you’ll never be able to ejaculate with anyone else, right?”

Her bluntness made me dizzy.

“And why are you two doing it if Miyu-chan doesn’t like you, and you want to be able to have sex with others?”

I don’t know. I can’t answer that. Half of it is my libido, but Miyu has no reason to indulge it.

Miyu softened after the toilet incident. She seemed to give up on something and gradually allowed more physical contact. It was a positive change for me, but why did she shift in a way that made me happy when she was angry?

Could it be, as Yamamoto-san suggested, that she actually likes me? Maybe she developed feelings while being intimate, and her previous behavior was just her being shy.

I still haven’t gotten an answer to why she so calmly drinks my semen. If it tasted amazing, I’d understand, but she’s said it’s disgustingly bitter.

Miyu has her own desires, and if she just wanted satisfaction, she has Haruka, her perfect partner. If she started this because she didn’t want to admit she’s a lesbian, then it doesn’t have to be me. Miyu is popular. There are better men than me.

She’s rejected all of them. According to Yuka, Miyu hates men, yet she’s sexually involved with me. If she truly dislikes men, including me, there’s no reason to deny being a lesbian.

If she only likes me, why doesn’t she confess? She avoids forbidden sibling romance, which she’s stated multiple times. It’s an unlikely assumption, but it explains her behavior.

But then, the biggest question: Why did she start helping me masturbate? We’d kept our distance, yet she pushed me to like her while saying sibling love is forbidden. There’s no trigger for this.

Nothing adds up. Since I can’t make sense of it, no one else can either.

“I really don’t know why Miyu and I are like this. I’d like to know too. Miyu won’t tell me.”

It’s a helpless situation, with no one to blame. If I could be honest, I wouldn’t have deceived this kind goddess.

“Your situation is complicated.”

Yamamoto-san seemed to understand, dropping her questions. Instead, she placed her hand on my head, combing through my hair. Her large, warm hands were comforting in a different way than Miyu’s.

“One thing’s clear: more options are better. Miyu definitely wants you to separate from her. Maybe she’s a saint, sacrificing herself to help you, even if it means being with her.”

“That’s quite something.”

Yamamoto-san smiled, continuing to stroke my hair. It felt like being soothed by my mother as a child.

“I want what’s best for Miyu. If separating is best, I want her to leave without worry, knowing I can have sex with others.”

I love Miyu. If she loves me, I’m happy, but I don’t want to burden her with my desires.

“So… despite this situation…”

I want to have sex with Yamamoto-san, if possible.

“Hmm. Then, one last honest question.”

“Anything I know.”

Yamamoto-san sat up, and I faced her. Her serious expression shifted to a smile.

“How many times have you did it with Miyu-chan since being with me?”

Her unexpected question made me cough. She smiled as I struggled.

“Do you mean… ejaculations?”

“Yes. You slept through the afternoon, so I assume it’s a lot.”

Damn, she’s enjoying this.

“Will you be upset if it’s a lot?”

“What kind of question is that?”

“Well… uh… let’s see… night and morning… so…”

Counting, I realized the number was absurd.

“Five times… maybe…”

Since being with Yamamoto-san.

“Include the ones you just omitted.”

“Ugh… well… actually…”

I admitted Miyu had helped me three times before our date.

“Wow. So lovey-dovey.”

Half of those were forced, though.

“Are you still okay?”

“Honestly, it’s tough.”

Including the wet dream, it’s eight times in two days. Is my body okay?

“Then let’s eat lunch and sleep.”

“That’s kind of you, but are you sure?”

“It’s no fun if only I enjoy it. I’ll cook quickly, so wait.”

Yamamoto-san went to the kitchen, reheating wrapped ingredients in the microwave and frying pan. She’d prepared lunch.

The guilt of oversleeping weighed heavier. I’d make it up to her in bed.

“You need stamina-boosting food.”

Soon, she brought dishes to the table: stir-fried chicken and nuts, Caprese salad, scallops and avocado with cheese, and unagi rice, with watermelon for dessert.

It was a killer menu, reflecting her expectations for our sex.

“Itadakimasu.”

Each bite energized me. The carefully cut ingredients and perfect cooking showed her love—universal, not just for me. This is Yamamoto-san’s kindness.

“Hehe. Dinner will have more stamina food, so eat up.”

Guess I’ll be drained again. My life will be work, sleep, and sex. What about summer homework? Maybe I’ll ask Yamamoto-san for help if we have good sex.

After the delicious meal, I received pajamas. They were women’s, but Yamamoto-san gave me the largest size, so they fit.

The bed was a spacious semi-double. Yamamoto-san got in first, patting the spot beside her. As I lay down, she pressed her breasts against my face. Her enthusiasm for the night was palpable.

“Don’t get too aroused and sleep.”

She smiled, stroking my head as my penis began to harden.

“We’ll have lots of sex when you wake up.”

Held in her motherly embrace, I fell into an unexpectedly peaceful sleep, despite it being daytime.
