My Little Sister Is the Best F*p Material - Volume 6 Chapter 02: Yamamoto-san, Who Will Do Anything Erotic I Ask

Volume 6 Chapter 02: Yamamoto-san, Who Will Do Anything Erotic I Ask

The live music venues where I was dispatched as an event staff member tended to narrow down to certain places after I’d done it a number of times. Once I got a feel for the locations that were within easy commuting distance from my parents’ house, close to the station, and easy to set up and guide people at, I started choosing those places exclusively.

Fortunately, no one suffered from heatstroke at my last part-time job. All that was left was to manage traffic while watching the festival, and I continued to watch the event unfold with the feeling of watching fireworks. It was then that I finally encountered someone I had hoped to at least say goodbye to.

“Agata-san!”

A woman who was short for an adult was walking aimlessly through the passageway. Even when I called out to her, Agata-san just looked around in confusion. There weren’t that many people in the passageway, but it seemed she couldn’t recognize me unless I got closer.

“Agata-san, thank you for your hard work.”

“Eh, ah, yes?”

Agata-san, facing me, acted as if we were meeting for the first time, and then she peered intently at my face.

“Sotocchi? Seriously? Eh, who are you?”

“What do you mean ‘who’ when you said it yourself?”

“Well… I thought maybe you had plastic surgery or something… and did you get taller?”

Is height something you can just increase if you want to?

“I haven’t changed either.”

“Is that so? Well, I guess you did look like this before, but something about your aura is different.”

Judging from Agata-san’s reaction, it seemed I had changed for the better somehow. If that was true, it was probably all thanks to Miyu raising me into a respectable man.

“There were various circumstances. Due to those, I’ve decided to quit this part-time job after this time.”

“Is that so? Well, this kind of work does have a lot of turnover though. I’ll be lonely without Sotocchi.”

“That’s why I wanted to say goodbye one last time. I’m glad I got to see you.”

After that, we chatted just enough not to get scolded by the chief and finished our work as time flowed by. Keitaro-san wasn’t there, but Agata-san invited me out for a meal again, and we decided to head to an izakaya together. Miyu apparently had dinner plans with her friends.

“Near the place we went together before is okay, right?”

“I don’t mind. There are a lot of izakayas around there, after all.”

The place Agata-san chose was a common chain restaurant with four-person and six-person sofa seats lined up, surrounded by low walls.

“Sotocchi gets more handsome every time I see you. Do you have a girlfriend this time?”

“Well, yes.”

“That’s the only explanation, huh?”

As we put down our bags and sat down, a waiter came to take our drink orders. Agata-san unreservedly ordered a beer, and I decided to have a non-alcoholic drink to match the atmosphere.

“What kind of person is your girlfriend? Could it be that ‘erotic’ one?”

“‘Erotic one’? Do you mean Yamamoto-san? It’s not her.”

“You know what they say, friends with benefits don’t become lovers. Is she someone you know from school?”

Agata-san pursued the topic without any malice. I knew this kind of probing would happen eventually. But facing the questions now, I didn’t know what to do.

How should I explain my relationship with Miyu to others? Pretending my girlfriend exists would be rude to both Miyu and the person I’m talking to, but the reality that sibling relationships are frowned upon in society won’t change no matter what, and if I come out with it, there’s no guarantee I won’t make Miyu feel bad someday.

“Well, she’s family.”

“Family? Like a friend from school? Or is it something you don’t want to talk about?”

“It’s more like it’s difficult to talk about. It’s a complicated relationship, so I don’t know if you’d believe me even if I told you.”

“Ehh, what’s that? Now I’m really curious. Maybe you can tell me if I get really drunk?”

Judging from Agata-san’s personality, I don’t think she’d react badly even if I told her. It’s difficult to say it straight out here, but if I build up to it and reveal the truth at the end when she’s tipsy, maybe Agata-san will take it seriously.

“I might tell you if you’re drunk, Agata-san.”

“Yosh! This big sister’s gonna drink a lot!”

Even so, I cautioned Agata-san to “take it easy,” and we toasted with our drinks that had just arrived.

“Agata-san, do you drink at home too?”

“Usually at the bar… but lately, it’s increased at home too.”

Agata-san paused meaningfully before muttering.

“Things are going well with Keitaro-san, aren’t they?”

“Hmm… our romantic relationship is fine, but…”

Agata-san heavily trailed off. I knew from experience that when people showed such an obvious attitude, they had something they wanted you to ask about, even forcefully.

She had only just started drinking, so she hadn’t blurted out her true feelings in a drunken stupor. It was likely that she had been harboring some dissatisfaction she wanted to confess since she first invited me, and she was hinting at it.

“Is there another problem?”

“Yeah. Well, um. It’s the alcohol, you know. Like an anesthetic.”

“Does Keitaro-san fall asleep when he drinks?”

“N-no, it’s me who gets drunk,” Agata-san said, gulping down about half a glass of beer. She then called over a passing waiter and ordered a few dishes and another beer.

“Just to confirm something… that sexy girl from before… Yamamoto-san? You two were quite close, weren’t you?”

“Yes, we were. For a short time, though.”

My physical relationship with Yamamoto-san only lasted about a week. The current situation feels different from just being friends with benefits.

“And this is just an intuitive question,” Agata-san said after a few moments of hesitation, finishing the rest of her beer and holding the glass with both hands.

“You did some… pretty extreme things…?”

Hiding her face behind the glass, Agata-san glanced at me. The intention behind this question is a subtle negotiation: ‘I want to ask you about some perverted stuff, so show me that you’re also perverted.’ If that’s the case, I should play along.

“Outside, perhaps?”

“Eh? You did? Where?”

“Ah, no, just lightly on the bus, you know?”

“That so, eh…”

She was completely taken aback. Maybe I went too far.

“Can I ask you something more blunt?”

“Please do.”

Agata-san lowered her voice, looked around, and made sure no one nearby could hear.

“Sotocchi, are you good in bed?”

Did things really progress this far before she even had much to drink? It seems the extreme things I revealed messed with Agata-san’s judgment.

“I don’t know how much of it is genuine, but I have been told I’m good.”

“Oh, really? That’s reassuring.”

So Agata-san’s problem is also about sex. I used to wonder why I only got those kinds of consultations, but talking to her like this made me realize something. Just like Yuka’s friends and Harumaki-san said, apparently I have an aura that makes people think it’s okay to confide their perverted worries to me.

“So,” Agata-san said, quickly downing the appetizer and the new beer the waiter brought.

“I have a very serious question.”

Agata-san straightened up and placed both hands on her knees.

“That… size thing. Would it make you uncomfortable if I asked about it?”

That was a question that went way beyond my expectations. “That” obviously referred to the male organ, but fortunately, mine is about average length, so I wouldn’t feel uncomfortable being asked. However, size perception varies depending on the girl, so it’s hard for me to say for sure if mine is big or small.

“I’ve never measured it, but it’s about average. It used to be on the smaller side, actually.”

“Used to be? What era are we talking about? It usually just grows with the rest of your body, right?”

“Apart from that, in the last few months, well, for some reason, only that part has been growing rapidly.”

“Is that even possible!? I’ve never heard of that.”

I’ve never heard any rumors about just the size of that part growing either. But as a matter of fact, the sole precedent exists right here. A magnificent specimen that miraculously grew through being trained by Miyu and Yamamoto-san, to the point where it could be considered impressive.

“How big is it in your hand? Sotocchi’s?”

“About the length from my middle finger to my thumb when they’re together, I guess?”

“Hmm, hmm. Is that about average for guys? Do they all say it’s just right?”

“I wonder. My girlfriend says it’s still too big for her, though.”

“Right!? See!? I knew it!”

Agata-san slammed her hands on the table and leaned forward. So that’s the kind of problem she has.

“Well, anyway, it’s a long story,” Agata-san said, leaning back against the chair and relaxing her shoulders.

“Sex with Keitaro is painful, and I don’t know what to do.”

Her boyfriend’s member is too big and doesn’t fit. That must be Agata-san’s problem. However, it feels like she’s slightly asking the wrong person for advice. I haven’t even gotten to the real thing yet with the wife who told me not to make mine any bigger.

“How big is it?”

“About the length from your wrist to the tip of your middle finger in your hand, roughly.”

“That’s quite something.”

There really are people in the world who are well-endowed. The problems I’ve dealt with so far have mainly been mental, so it’s difficult to give advice on practical matters. Even though I have a lot of experience, most of it was just going with the flow.

“Doesn’t it get easier with practice?”

“I thought so too, and we’ve done it about ten times already, but it still hurts so much I want to scream.”

“That sounds rough.”

I wonder if mine will become too big and I won’t be able to do it with Miyu anymore. Miyu apparently has developed the sensitive areas deep inside her vagina, but she said she hasn’t inserted any thick toys. Maybe it would have been better if she had just loosened the entrance for me.

“Sotocchi, have you ever been with a virgin?”

“Yes, I have. She had already developed it with toys, so it didn’t hurt, apparently.”

“It’s rare to go that far with solo play, huh?”

“I suppose so.”

Unfortunately, it wasn’t solo play; it was forced development as punishment, but I don’t have the confidence that she’d understand about Yuka, so I’ll keep quiet.

“Is that your current girlfriend?”

“No, I have no experience with her.”

“Eh!? Really!? I actually thought you were the type to start with sex…”

“We haven’t done the real thing yet.”

My relationship with Miyu was unusual, even without considering that we were siblings. She’d drink my semen even though we weren’t lovers, but it wasn’t for sexual gratification, just semen disposal. And I’d regularly receive erotic punishments, while our non-lover relationship remained the same, only the intensity of the eroticism increased.

“Doesn’t it bother you, Sotocchi, not doing the real thing?”

“Not really. But that’s based on the premise that my ideal lover is the one I’m with, and she makes me feel good in other ways even without the real thing.”

“So, she’s super cute and has amazing technique, huh?”

I can’t deny that.

“So, what’s she like?”

Agata-san had unknowingly finished her third drink and casually asked as she ordered her fourth. She wasn’t exactly drunk, but the atmosphere was warm enough.

“This will be a story you might not believe, but is that okay?”

“You’ve built it up this much, so I’ll believe you if you tell me.”

“She’s my younger sister.”

“……Hmm.”

Agata-san closed her eyes and repeated my words to herself while the waiter brought her beer, keeping silent.

“I’ll have another drink.”

“Go ahead.”

Agata-san seems like someone who can handle her alcohol normally. If she’s drinking this much every time she has sex as an anesthetic, it would be quite an expense and hassle.

“Would it be okay if I had a photo viewing time?”

She wants to believe my statement, but the fact that she’s my sister is probably hard to accept, so she wants more information. But I don’t have any photos I can show. There’s no way I can show her photos of Miyu in loli outfits making erotic faces.

“I have her profile picture on a messaging app, though.”

I remembered that Miyu’s profile picture on the app was a photo from their trip with Haruka and the others. It’s something publicly available, so it should be fine to show her this much.

“If this is alright.”

I zoomed in on the icon and showed my phone to Agata-san, who stared intently at it.

“Everyone’s cute, aren’t they?”

“Yes, they are.”

“But aren’t they super loli-looking!?”

“Well, yes…”

After all, from Agata-san’s perspective, they’re quite a bit younger. Even though they’re all mentally mature, Miyu and Haruka definitely have loli figures, and even though I’m only two years older, it’s a borderline age.

“So, which one is your younger sister?”

“The one on the right with the strong cat-eye makeup.”

“Uwoh…”

Agata-san took the phone and zoomed in with two fingers. Their faces were clear enough even in the full picture, so I knew without being told that Agata-san was interested in Miyu’s chest.

“Are all the girls around you erotic?”

“I wonder.”

I can’t deny that either. I’ve been involved in the sex lives of almost every girl I’ve met.

“Isn’t it kind of messed up that you always get this girl to relieve you without doing the real thing?”

“It is messed up.”

“Seriously, her boobs and face are unbelievably hot! How is it possible that someone like that has amazing hand and mouth skills!? And she’s your younger sister and your lover, what the heck!?”

“Well, I understand how you feel, but please calm down.”

This is the reaction of a normal person. It’s actually milder because she’s had some alcohol.

“It doesn’t feel real, but I have no choice but to believe it. Sotocchi has become so handsome, he was friends with benefits with Erotic-chan, and his younger sister is super erotic, so I have no choice but to believe it. Or rather, his sister is too erotic… living with someone like that would drive me crazy… what are those boobs… I want to grope them too…”

I wonder if she’s finally convinced. It was the right decision to drag it out until the latter half. It would be nice if other people accepted it like this, but there are also people with extreme views in the world, so it’s probably best not to talk about it in general.

“I wish I had the technique too. Erotic-chan and your sister are both so cute. Is this the level you need if you’re not doing the real thing?”

“It’s a difficult question to answer, but it’s true that she’s unbelievably cute.”

“Right? Haa…”

Unfortunately, I don’t think I can solve Agata-san’s problem of her boyfriend’s member being too big. It seems the only way is to gradually buy larger toys and expand.

“But it’s okay. I feel better after talking about it.”

“Is that alright?”

“It’s not like I didn’t know from the start that I’m the only one who can really do anything about it.”

Certainly, no matter what I said, since it’s a couple’s issue, only Agata-san’s actions could resolve it. My past self might have wondered why she brought her problem to me then. But I’ve gained enough experience to understand that this is what girls’ complaints are like.

“Sotocchi, you listen to even this kind of stuff so calmly, it’s really reassuring. Actually, I consulted a few other people too, but it just ended up stressing me out more, and I got sick of it.”

This time, Agata-san openly showed her displeasure, took another sip of her beer, and placed the glass heavily on the table.

“You could also say I’m just not very interested in other people’s problems,” I offered.

“You should just take it as a good thing, about yourself. That tendency to be so self-protective is your bad habit, Sotocchi.”

Agata-san rudely pointed the tip of her chopsticks at me. I slipped into a bad habit again. I’m aware of it myself and want to fix it quickly. Even so, considering how much she’s drunk, it’s a fair amount, but it seems like too much for her usual self.

“Did something happen?”

“Did something happen? Everyone’s been sexually harassing me! Even though I have a boyfriend, they say things like, ‘If you’re so worried, why don’t you try me? Mine’s small, so it’ll go in easily, you know?’ It’s not like I want to have sex with your pathetic little thing!”

Agata-san’s voice gradually became rougher. Her anger seemed to escalate with every word she spoke.

“There are also guys who just preach at me, saying things like, ‘Isn’t Agata also responsible? You have to try to make it go in yourself.’ Why would they assume I haven’t tried? I even swallowed my pride and bought a big toy! And when he can’t make me come during sex, I use my hands or mouth until the end, you know? It’s not my fault that it’s too big to fit in the first place, so where’s my responsibility?”

Lecturing someone who has come to you for advice is the worst thing you can do. Speaking based solely on your own perspective and common sense often leads to making presumptuous statements that make the other person uncomfortable. That can also lead to secondary problems.

“And when I can’t take the irritation anymore, I get angry, but then they say, ‘Then why didn’t you say that earlier?’ Well, there’s an order to things, and you’re the one who made me not want to say what I wanted to say, and besides, do you think I can casually say, ‘I use a toy by myself’? And they say, ‘You’re the one who asked for advice, right?’ Then don’t butt in! Being irritated by my problem and being irritated by talking to you are two different things!”

Then, Agata-san chugged down her beer and sulked. She seemed like she wouldn’t be able to go home on her own if she drank any more, so I stopped her.

“But!”

Agata-san’s expression suddenly brightened. Do people’s moods really change this drastically when they’re drunk?

“You’re not like that, Sotocchi, so just talking to you makes me feel relieved.”

“I see.”

Not many of the people around me showed this kind of negative side, so getting a glimpse of a woman’s true feelings is a valuable experience.

“I’m glad if my presence stopped the bad luck.”

I understood that my evaluation was relatively high compared to the people around Agata-san. 

However, running into someone who just preaches like that can only be described as bad luck. 

There are plenty of handsome guys in the world who are good listeners.

“The sense of security I feel with you, Sotocchi, is a little different from other people.”

Resting her folded arms on the table, Agata-san continued to speak sleepily.

“For some reason, I feel like even if I show you my raw, questionable self, you’ll definitely take it seriously.”

Agata-san rubbed her cheek against her folded arms as she looked up at me, then suddenly sat up straight and pointed at me.

“And that sense of security is also part of your sexual appeal. That’s why I can easily talk to you about dirty jokes. And this is a secret, but you also have this mysterious aura that makes me want to get a little erotic.”

“Isn’t that a bit much coming from someone who has a boyfriend…?”

I also understood from my time with Yamamoto-san that affection and lust are separate things.

“The sky is blue even if you don’t know why, right? It’s like that.”

“I see, so that’s how it is.”

I had absolutely no idea what she was talking about. It’s probably something not worth knowing. 

I know that from experience too.

“And so, tell me more about your girlfriend.”

After that, Agata-san and I stayed at the restaurant until we were tired of talking, engrossed in trivial personal stories. In the beginning, Agata-san had doubts about the romantic relationship with my actual sister, but once we had revealed our deepest selves to each other, a 

self-deprecating atmosphere of “well, humans are just animals like that anyway” enveloped the place, and after accepting it, Agata-san even became supportive. It doesn’t always go this well, but it’s always nice to have more people understand.

When we left the restaurant, the night sky was clear of clouds, so the humidity was low and a cool breeze was blowing. Agata-san and I walked towards the station with light steps. On the way, Agata-san suddenly stopped and turned back to me

.

“I think I want to be healed by Erotic-chan’s boobs.”

She suddenly blurted out such a middle-school boy’s desire, but before I could even feel confused, I was dragged to the izakaya where Yamamoto-san worked.

“I don’t know if she’s working or not, you know.”

“It’s fine, it’s fine, even if she’s not there. She might be carrying beer bottles again.”

“Please don’t tell me you’re going to wait until she comes out.”

And so, when we arrived at Yamamoto-san’s workplace, Agata-san first looked around. There was no way she’d be found that easily, so Agata-san called out to the cashier who was ringing up a customer as they left the store.

“Excuse me, is Yamamoto-san here?”

“Yamamoto? She just left. She was on an early shift from lunch. Did you need something?”

“Ah, no, never mind then. Sorry to bother you.”

I was surprised that a young man who looked to be in his early thirties suddenly spoke so casually to someone who was likely a customer, even if they knew Yamamoto-san, but apparently, he was the manager.

“Damn it, a near miss! Sotocchi, let’s run and catch her!”

Agata-san cheerfully started running and dashed about a hundred meters towards the station before stopping with a pale face.

“Crap, my stomach’s killing me from chugging that beer.”

“You drank too much. Let’s give up on Yamamoto-san and go home quietly.”

“Okay…”

Alcohol makes people act strangely. I learned that firsthand, so I decided to consider this a good opportunity. Agata-san and I were together until the ticket gates, and from there, we took different trains home. Before the stairs leading to the platform, Agata-san and I waved goodbye without any particular reluctance.

The train was moderately crowded, and I could occasionally hear people talking from the corners near the doors. The fatigue from my part-time job had mostly recovered after resting at the izakaya, but the atmosphere of the place had made me feel a bit tipsy and excited. So, I would have preferred to sit down and relax.

(I’ve been so worried about other people, but I don’t even know what I’m like when I’m drunk.)

When it comes to finally being intimate with Miyu, there’s a line I must not cross. Now that our relationship as lovers has deepened, if I get drunk and lose control, Miyu might go wild with me. I’d be in trouble if I accidentally got Miyu pregnant, so I probably shouldn’t drink for a while even after I turn twenty.

“Getting a girl you’re alone with drunk is the first step to cheating, you know.”

A teasing voice came from behind me, and when I noticed, a woman with long black hair was reflected in the door window. It was that erotic beauty.

“Did you notice me?”

“You were making so much noise, you were hard to miss.”

When I turned around, there was Yamamoto-san, a tall, busty, and curvaceous beauty. I hadn’t seen her when I first got on, so she must have gotten on through a different door while noticing me.

“That person was someone I worked with at my part-time job. Today was my last day, so we were having a farewell party.”

“Putting aside the fact that you were drinking alone with her. Drinking with a girl one-on-one until she’s drunk is undeniable proof that she trusts you. Sotomichi-kun, you should learn that soon, or you’ll become a hopeless ladies’ man.”

Yamamoto-san flicked my forehead with her index finger. That’s certainly something I need to be careful about. I have to remember that.

“Yamamoto-san, you’re also coming from work, right?”

Yamamoto-san was wearing a large shirt with a high-waisted skirt, and she didn’t look like she had just worked at an izakaya at all.

“Ah, this? Our uniform is a top and bottom set. I was being worked hard for cheap pay again today.”

Yamamoto-san has such model-like looks, yet she works a low-paying job with an hourly wage of 820 yen. There’s a possibility she just likes the atmosphere of the izakaya itself, but maybe Yamamoto-san, like me, lost her confidence due to past troubles.

“Yamamoto-san, don’t you ever tutor or something?”

“Why?”

“It seems like you could easily find a part-time job that pays much better.”

“Ah, yeah. I wonder why.”

Yamamoto-san shrugged and gave a vague answer. Well, living by instinct is a perfectly valid option. If anything, I’m on that side too. But from Miyu and Kawato’s perspective, Yamamoto-san didn’t seem to be the same type.

“Sotomichi-kun, you look good in a suit too. You have a solid build, so formal wear really suits you.”

“Thank you. Yamamoto-san, you look good in anything.”

“Well, that’s because the base material is good.”

Yamamoto-san traced her finger from the swell of her chest down to below her skirt. Her breast size is something, but the legs extending from her short, raised skirt are just so erotic. I wonder how many people’s gazes she captivated today.

“Doesn’t the thought that only Sotomichi-kun can violate this body completely excite you a little?”

Yamamoto-san must have sensed my dirty thoughts, as she whispered with her hand cupped around her mouth. If I took her seriously, I wouldn’t be able to gloss over my agreement, so I just gave vague replies while mindlessly reading the words on an advertisement.

“Did Miyu-chan say anything to you after you got home yesterday?”

“She did. She said, ‘Just let her do it to her heart’s content.'”

“‘To her heart’s content’? Does that mean she’s okay with you going on dates and having sex with me as much as you want?”

“It seems so.”

Come to think of it, my date with Yamamoto-san was also yesterday. The sex last night and this morning was so intense that it felt like it happened days ago.

“Hmm, hmm. Maybe I underestimated Miyu-chan’s possessiveness. Then I guess I can’t hold back anymore.”

Yamamoto-san, on the contrary, seemed convinced by Miyu’s response and looked at me with clear, determined eyes. What kind of psychological warfare is going on between Miyu and Yamamoto-san?

“She’s allowing me to have sex with other girls, yet she’s possessive?”

“It seems Miyu-chan doesn’t like the idea of me having even a shred of lingering feelings for Sotomichi-kun. I think she wants me to go all out, so I have no regrets.”

I see, if you think about it that way, it’s very much like Miyu. When she decides to do something, she does it thoroughly. That’s just her nature. Even if she genuinely said it’s for Yamamoto-san’s sake, that’s separate from Miyu’s own feelings. She must also want a clear break for herself.

“In that case, I need to have sex with Sotomichi-kun right away!”

Yamamoto-san made a guts pose with both hands and looked at me with expectant eyes.

“You want to?”

“I do.”

“You want to that much?”

“I want to, so, so much.”

Perhaps because she no longer has to hold back for Miyu’s sake, Yamamoto-san was just blurting out her true feelings. I liked the girlie, romantic Yamamoto-san from yesterday, but I also like this honesty, not being ashamed of her own sexual desire.

Since it’s a waste of time to worry, we decided to do it at my place and headed for the bus stop. Actually, I have a date scheduled with Yuka too, but I guess doing it once won’t hurt. And then, on the way, we stopped in front of a karaoke box that caught my eye.

“Karaoke, huh? It’s expensive at night.”

“If you think of it as a private room for thirty minutes, isn’t it cheap?”

Certainly, when looking for a place to be alone together, karaoke is a cheap and convenient option.

“Are you okay with security cameras?”

“My friend said there aren’t any here.”

So, Yamamoto-san talks about things like that with her friends, huh.

“Oh, I’m just listening, okay? At school, everyone thinks I’m a virgin. So please handle that part accordingly.”

“Nobody even knows you had a boyfriend, right?”

“That’s right.”

The thing Yamamoto-san was most worried about regarding the Suzuhara situation was losing her standing at school. The people she had dated in the past were considerate and took care not to let any information slip at school. Whatever kind of breakup she had, they all ended up wanting to protect her, which shows just how much she has been there for everyone.

“Shall we go in?”

“Yeah!”

I was the one who urged us to enter. Both Miyu and Yamamoto-san had made up their minds, so I felt it was unfair for me to remain passive.

“Two people, thirty minutes, please.”

We were led to a room for two, but it was spacious enough to have a blind spot from the window on the door. If we turned off the lights in the room, the reflection would make it almost impossible to see inside. So, hiding behind the table would be enough to do a blowjob, but having as many reassuring factors as possible is a good thing.

“Sotomichi-kun, quickly, quickly.”

Yamamoto-san squatted down in the blind spot, showing that she wanted to start right away. This 30-minute course is all-you-can-drink, so unlike a one-drink minimum, there’s no need to worry about the staff coming into the room.

“I’m just saying, I’ve been working all day…”

“It’s okay, I’ll lick it clean, right? Leave it to me.”

Yamamoto-san actually looked happy as she stroked my crotch. I thought she wouldn’t mind, but still. This feeling of being able to do anything is making me feel so horny.

“Then, this.”

I unbuckled my belt, lowered my zipper, pulled down my pants and underwear, and pointed my cock at Yamamoto-san. From the moment I opened the zipper, the smell of sweat and semen drifted out, and Yamamoto-san deliberately brought her nose close to smell it, and then licked the tip.

“I kind of like Sotomichi-kun’s stuffy semen smell, and I also like the slightly salty taste at first.”

Yamamoto-san didn’t immediately take it into her mouth. Instead, she smelled and licked the back of my balls and the inguinal region in the same way. From both sides of the room, we could hear the singing voices of other customers, and in the midst of all that, we were indulging in a blowjob without even selecting a song.

“I’m going to take it in now.”

Yamamoto-san, breathing heavily and at the limit of her endurance, inserted my erect penis deep into her mouth.

“Mmf…throb…gurgle…slurp, squish…!”

“Uah…ah…!”

The voices of amateurs singing, the talking in between the songs, and the sound of the staff’s footsteps passing right in front of the door, gave me a sense of danger and excitement, as my lower body was exposed.

“Hwa…delicious…mmff…slurp…ah. In this position, you definitely can’t see from outside.”

“Right, yeah.”

I’m worried that the staff will think it’s suspicious that there are people in a room without any lights or music, but the structure of this room with a complete blind spot from the door is quite suitable for having sex.

“There’s something I want to ask of Yamamoto-san.”

Miyu has told me that it’s okay for me to become good friends with Yamamoto-san to the point that she becomes serious. That included the nuance that I should enjoy going on dates and having sex with Yamamoto-san.

“Would it be okay if you took something off?”

From earlier, I couldn’t stop thinking about Yamamoto-san’s swaying breasts every time she moved her head. I’m afraid I’ll be scolded for always thinking about breasts, but I think it would be rude to be indifferent to a woman’s body that has produced such beautiful fruit.

“Sure. How much should I take off?”

Yamamoto-san agreed without a moment’s hesitation. I only need to touch her breasts, so I can touch them if she takes off her bra and opens her shirt buttons.

“How far can I go?”

However, since we’re doing this in a place other than home, I can’t help but be mischievous.

Okay, I’ll redo that last response with more authentic Japanese SFX. Here’s the edited translation:

“Even if you ask ‘how far?’ If you want me to take it all off, I will.”

“All…!? Is, is that okay?”

“Fufufu. If you’re interested, shall I?”

Yamamoto-san started taking off her clothes before I could even tell her to. Her fingers removed the clothes that had been covering her upper body, and when she unhooked her bra, her beautifully shaped breasts spilled out with a purun (ぷるん – bouncy) movement.

“You’ve been staring at my boobs the whole time, haven’t you, Sotomichi-kun?”

“Sorry…”

“If they please you, then I couldn’t be happier.”

Yamamoto-san took my hand, which had been looking down, and guided it to her breasts. Being treated like a virgin like this sometimes makes me feel a stronger sense of motherhood than a feeling of being looked down on, and I feel like I’m going to drown in Yamamoto-san’s sexual love.

Yamamoto-san’s breasts are so soft that my fingers sink into them. When I grabbed them tightly, plump fat spilled out from between my fingers. And I kneaded that reaction that spread throughout the palm of my hand according to my desire.

“Does it hurt?”

“It doesn’t hurt, and I wouldn’t mind if you hurt me.”

Yamamoto-san watched me obsess over her breasts with a seductive look, then unbuckled her skirt and let it fall to the floor with a suton(thud). Then, while still squatting, she pulled down her panties, revealing all of her soft, bare skin.

“Should I take off my socks too?”

“I like them the way they are.”

“Understood.”

Yamamoto-san, who listens to every request, let me fondle her breasts while she was naked except for her socks and started sucking on my penis.

“Hamu…hauaa…habuchu, juruchubuchu, nn…guchu!”

“Ah, aah…!!”

Yamamoto-san sealed her mouth tightly to my swollen penis, and every time her face moved back and forth, the sound of air being crushed echoed in her mouth with a buchubuchu (squelching) sound. As expected, it was Yamamoto-san, and I was already genuinely enjoying this situation from the bottom of my heart. Perhaps Yamamoto-san was getting that message as well, as she gave me a naked service blowjob while her face was breaking into a smile.

It was different from her usual rampages. Yamamoto-san was simply happy that I looked comfortable, returning to the sex we had before. I still like the Yamamoto-san who cherishes my pathetic appearance, this saintly woman, the most.

“Ya-Yamamoto-san…”

“Hmm? Fufu. What is it?”

Yamamoto-san, dressed in a way that even those watching would feel embarrassed, raised the tone of her words as if to meet the eyes of a child.

“Would you get mad if I asked you to spread your legs…?”

“I wouldn’t get mad. I’d be very embarrassed, but if that’s what you want, I’d be happy to be embarrassed.”

Yamamoto-san said that and, still squatting, spread her legs, revealing her private parts. There, her slit, dripping with love juice, was wide open, and even the protrusion of her clitoris could be clearly seen. There were no obstacles blocking my view.

“Yamamoto-san, didn’t you have a little bit of hair before?”

“Miyu-chan said she didn’t have any, so I tried shaving it. Then, it ended up being surprisingly neat.”

Yamamoto-san turned her face away shyly, now that it was too late. Miyu’s body type is loli-like, so a shaved pussy suits her, but when a mature woman like Yamamoto-san is clean-shaven, you can experience a different kind of excitement due to the gap.

“I might seriously fall in love with that kind of sexy side of you, Yamamoto-san.”

“You only say nice things at times like these.”

Yamamoto-san plunged my penis deep into her mouth again, as if to vent her frustration. Even so, because it was my request to open her legs, she didn’t try to close them, no matter how embarrassed she was.

While even harboring feelings similar to love for Yamamoto-san, I stared intently at her chest while I fondled it. Then, Yamamoto-san started giving me a more intense blowjob to hide her embarrassment, and something of my masculinity awakened in me at the sight.

“Ah, aah… Yamamoto-san, just like that, take it all the way to the back…!”

I moved my hips myself and pressed my penis all the way to the base into Yamamoto-san’s mouth. While fondling Yamamoto-san’s plump breasts, I crouched down and violated Yamamoto-san’s mouth with my penis as if inserting from the rear.

“Nn, fuu…njuggu, chubu…! N, kufaa, haa…nnn…!”

Every time I moved my hips back and forth, the muscles in Yamamoto-san’s face lost their strength. It was only after Yamamoto-san arched her body and came intensely that I realized that it was a sign of orgasm. Yamamoto-san’s nipples hardened like rubber stoppers, saliva seemed to spill from her mouth, and her brain mistook the fact that she was in the same state of suffocation as during orgasm, leading Yamamoto-san to a forced climax. Even then, her revealed secret slit was twitching, and the floor was wet as if she had leaked urine.

“Kafu…aa…haa…it felt so good, I thought I was going to die…”

Yamamoto-san breathing heavily with a blissful expression. Seeing her face enjoying even that situation, I could no longer stop my desires.

“I’ve started wanting to suck on Yamamoto-san’s breasts. Is that okay?”

There’s a rumor that massaging breasts makes them smaller, so Miyu even allowed me to touch her breasts with my hands. However, she is still resistant to acts that promote the secretion of female hormones, such as sucking on her nipples.

In that case, I have no choice but to suck on Yamamoto-san’s breasts. I haven’t sucked on them for a while, so I’m already experiencing mild withdrawal symptoms.

“You want to suck my breasts?”

“Yeah. But if that happens, you won’t be able to do it with your mouth, so Yamamoto-san might be troubled.”

“I won’t troubled at all.”

Yamamoto-san knelt in the empty space on the sofa and brought her breasts close to my face.

“If Sotomichi-kun says he wants to suck my breasts, I’ll let him suck them. If he says he wants me to suck his penis, I’ll suck it. That’s my reason for existence right now.”

“If it goes that far, it’s practically like a sex slave…”

Even in a fantasy world, there aren’t slaves who listen this obediently.

“Sotomichi-kun’s sex slave, huh? That’s a very attractive job offer, but do I have the qualifications to apply?”

“Qualifications aside, I’d prefer it if Yamamoto-san would listen to my lewd requests in a relationship that’s not as a slave.”

“Ah, that makes me so happy.”

Yamamoto-san hugged me so tightly I thought she would suffocate me with her breasts.

“Sotomichi-kun, suck as much as you want.”

“Then, I won’t hold back.”

Yamamoto-san’s nipples are a little bigger compared to Miyu’s, and the areola is still a light color, showing that I really was the first person to suck them, like she said. I挟んでmy lips around it, and enjoyed the korikori (slightly hard, crunchy) texture with my tongue and lips, before sucking hard enough to make a sound with a chu.

“N, haa. Ever since having sex with Sotomichi-kun, it seems like my nipples have become more sensitive. N’aa, aa, that feels good.”

Yamamoto-san continued to breathe heavily at my tongue work, while continuing to stimulate my penis with her hand instead of a blowjob. Even though I’m wearing a suit, it’s pathetic to think I’m doing something like a baby. That also turns into sexual pleasure and bubbles up, and maybe I wanted Yamamoto-san to see me in this state, so I asked her to let me suck her breasts.

“Faa, nn, Sotomichi-kun is good at sucking breasts, isn’t he? There there. I’ll pet you up and down a lot, okay?”

And Yamamoto-san is also aware that I’m getting excited by being treated like a child. That’s why she treats me like this, as if she’s comforting me. When it comes to perverted sex, I can vouch that Yamamoto-san is the best.

“Aa, shit. I’m starting to cum.”

The excitement about this situation has become more intense than the stimulation given by handjobs, and my desire to ejaculate is overflowing and unstoppable.

“You want to cum?”

Yamamoto-san asked as if breathing into my ear.

“I, I want to cum, but there’s still a little time left…”

We only used half of the thirty minutes we took. I’m dying to ejaculate, but if I come here, I’ll make Yamamoto-san feel unsatisfied again.

“It’s okay, come. It’s my greatest joy for Sotomichi-kun to ejaculate comfortably. I’m very satisfied today.”

Yamamoto-san speeds up her stroking of my penis and encourages me to ejaculate. When it comes to this, I have no choice but to let go of my desires.

“Sotomichi-kun, you came before when you looked at a picture of me that looked like Miyu-chan, right? If you think of me as Miyu-chan when she grows up, won’t you be able to ejaculate?”

When I was shown a picture of Yamamoto-san from the past, I was surprised that it looked so much like Miyu. And I even came to the point of ejaculating from both the picture of Yamamoto-san from when she was little, and the picture of the current Yamamoto-san that had been processed to look like Miyu.

“Apart from your little sister, if you had an older sister, I’m sure it would be something like this. I’m sure Sotomichi-kun would even ejaculate with his older sister, wouldn’t he?”

“A, aa, that’s…haa, haa, u…aa…!”

The fact that her past appearance is similar to Miyu means that Yamamoto-san is genetically quite close. As Yamamoto-san says, she may have been another sex partner who could have been an okazu (side dish, in this case, a sexual fantasy).

“Aah! U-Ugh!?”

The moment Yamamoto-san’s fingers, stroking my penis, rubbed my glans, the leading group of sperm, which had been cursed and prevented from being ejaculated, finally raced through my urethra according to their desires.

“Ah, a little came out.”

Yamamoto-san scooped up about a grain of adzuki bean worth of semen with her finger and kneaded it and stretched it out nebaneba (sticky).

“Sotomichi-kun, were you thinking about Miyu-chan just now?”

“I, I wonder…”

I wasn’t specifically remembering having sex with Miyu, and I wasn’t imagining Miyu’s voice or appearance like I usually do. Even so, there’s no doubt that Yamamoto-san mentioned the word Miyu, and I was thinking about the pictures I had been shown to ejaculate before, so I still think that I can’t cum without using Miyu as a okazu. However, to that extent, the desire to ejaculate I felt for Yamamoto-san was ambiguous as to which it was due to.

“Fufu. You fell sooner than I thought.”

Yamamoto-san smiled slyly and licked the semen she had been playing with off her finger.

“Don’t tell me, from the beginning…”

“I was just thinking about it as a possibility when I was processing the pictures. I didn’t think I’d have a chance to have sex with Sotomichi-kun to this extent.”

In short, it was a knowing, yet unplanned offense.

“Sotomichi-kun can ejaculate if he’s thinking about Miyu-chan, right? In the end, it’s just a matter of how Sotomichi-kun recognizes it.”

With a picture of Yamamoto-san that closely resembled Miyu, I easily ejaculated. Already at that point, I felt something close to Miyu in Yamamoto-san.

“You can come without Miyu now?”

“Maybe. Let’s check, shall we?”

Yamamoto-san flipped up my shirt and pushed me down onto the sofa, then pulled down my pants while moving my hips further back. Then naked except for her socks, she straddled me and lined up my penis with her slit, as if fitting it into that groove.

“In this position, we’re visible from the door window.”

“Fufu. That’s right.”

Even though she must have understood the meaning of my words, Yamamoto-san leaned her body forward and pressed her plump, swollen, lewd “pacifier” against my mouth.

“I have good hearing, so don’t worry.”

Yamamoto-san gently moved her hips back and forth, smearing the love juice gushing from her secret slit onto my penis. While ignoring the hallway, where anyone could pass by at any time, I sucked on Yamamoto-san’s breasts and hardened my penis. My free hand unconsciously kneaded the other breast, and I felt like I couldn’t resist this intense motherhood at all.

“Sotomichi-kun, endure without thinking about Miyu-chan, okay? If you ejaculate then, it means Sotomichi-kun can use me as okazu.”

Yamamoto-san was leaning her body diagonally forward to support herself, so I could suck on her breasts. Doing a somata (dry humping) in that state rubbed her nikuga (granulation tissue, often used to refer to the inner flesh of the vagina), and Yamamoto-san seemed to enjoy it.

“Sotomichi-kun’s worries can finally be resolved.”

It was no longer an obstacle for me. Because I’m bound to my little sister, this constitution of not being able to come unless I use her as masturbation material was no longer a problem at all. Rather, it should have been a proof of the strength of the bond between me and Miyu.

I sucked on Yamamoto-san’s nipples, and enjoyed the pleasure without resisting. Yamamoto-san’s writhing hips was already wet making me wonder if we really weren’t inserting.

Lifting one of Yamamoto-san’s breasts to the side, and somehow confirming the situation in my groin, I saw that my glans was repeating the actions of showing and hiding like when being given a paizuri (boobjob). My entire penis was shining with Yamamoto-san’s wet fluids, and trembling at every moment I felt the softness of raw flesh.

“N, ah… Sotomichi-kun’s, hard and feels good… I want to put it inside…”

In the gaps between the surrounding music, I could hear lewd sounds like guchu, guchu (squelching). If I inserted in this situation, I would definitely not be able to stop until I came inside. Knowing that, I was again about to have my male instincts drawn out by Yamamoto-san.

“Yamamoto-san, let me ejaculate already.”

I had been pushed to the verge of ejaculation with the handjob from earlier, so my endurance was already at its limit. If I continued to be tormented with pleasure, my reason might fly away. It was a painful decision to deny the constitution that was a proof of my love for Miyu, that I had to use my little sister as a masturbation material, but I felt like something bad would happen if I didn’t ejaculate here.

“You’re about to come? Sotomichi-kun?”

With a face faintly immersed in superiority, Yamamoto-san lowered her hips deeply and buried my penis in the groove of her flesh. A feeling of fleshiness different from a blowjob, and a stickiness different from saliva, gave my sensitive zone an unprecedented stimulation and aroused me.

“A, aa, ya, Yamamoto-san…!”

“Fuaa, aah, Sotomichi-kun… it’s dangerous if you move your hips…!”

Seeing Yamamoto-san about to lose control as I arched my hips as I wanted, I hurriedly stopped moving. If we moved our hips reciprocally, I would be dragged by the feeling of wanting to come inside.

“If you want to move that much, you do it, Sotomichi-kun.”

When Yamamoto-san raised her hips, her love juice spilled out like dripping lotion that had been kneaded in. Then, Yamamoto-san stood again in a position where she couldn’t be seen from the door window, put her hands on the wall, and called me.

I stood behind Yamamoto-san as I was led. Then, Yamamoto-san sandwiched my penis between her thighs, and made me grab her breasts in each of my hands.

“Violate me.”

Yamamoto-san looked at me with expectant eyes, and then entrusted her naked body to me. It was Yamamoto-san’s onedari (pleading request) to rub my penis against her crotch and ejaculate.

“Ya-Yamamoto-san──!”

My waist was moving naturally. As animals should be, up to the point just before reaching the reproductive act, I was unconsciously performing the action.

“Hann, aa, aaaah…! Sotomichi-kun’s… touching it, feels goood…!”

My penis, so erect it felt like it would burst, was pressing against Yamamoto-san’s secret slit with upward force, and the bulbous glans was rubbing against her clitoris, making Yamamoto-san groan. I frantically rubbed her breasts and grabbed both nipples with my fingertips to teach a lesson to the slut who enjoyed being violated from behind.

“Hiyaau…Ann, Auaaaa! So, Sotomichi, kun…Ihya, it… feels too good…!!”

As Yamamoto-san yelled my name and groaned, I slammed my waist violently, as if scolding her by hitting her buttocks next. Pan! Pan! (slapping sound) Resonating explosive sounds rang out in the room, and I could tell from Yamamoto-san’s panting that she was getting excited by the sound, and my lower body also trembled with joy.

Taking advantage of the fact that it was a soundproof room, we devoted ourselves to the imminent intimacy by vocalizing our pleasure. Lecherous sounds echoed, and it melted our brains like hypnosis. If I kneaded her breasts, Yamamoto-san’s cheeks relaxed, and if I pinched her nipples, her thighs tightened  tightly, and when I inserted my penis as if twisting it in there, Yamamoto-san made a shrill squeal and wriggled.

This lewd girl must be punished. The bewitching woman who seduces men and makes them crazy will be reformed with my penis.

I want to have sex. I want to insert into Yamamoto-san’s lewd hole and ejaculate until it overflows.

“Yamamoto-san… I’m gonna… cum…ッ!!”

I was at the limit of my reason. If I continued any further, my instincts would cause Yamamoto-san to become pregnant. I had to somehow ejaculate and put an end to it, or I would lose everything.

“Hya, i, aah, aaa! Let it out! Cum!”

The “let it out” cry from Yamamoto-san, whose enunciation was beginning to falter, flipped the switch for my ejaculation. Intent on releasing the semen surging through my urethra onto Yamamoto-san’s back, I pulled my hips back at the moment of ejaculation.

“Cumming──!”

That final movement of pulling my penis out strongly rubbed against Yamamoto-san’s clitoris, which was pulling her hips back, and that stimulation led to Yamamoto-san’s greatest climax. At the same time I ejaculated, Yamamoto-san’s waist, her legs losing their strength, collapsed, and I gushed my semen  into the warm, slick flesh.

“────!?”

Supporting Yamamoto-san so she wouldn’t fall, I desperately pulled out my penis amidst my agitation, regained my footing, and released the rest of my semen near Yamamoto-san’s tailbone. I hadn’t anticipated Yamamoto-san falling, and a mild panic set in at this unexpected turn of events.

“Yamamoto-san, are you alright?”

“Yeah. Sorry. I’m not used to coming yet.”

After confirming that Yamamoto-san had calmed down a little later, I told her that I had ejaculated around her crotch. Then, Yamamoto-san put her fingers inside from the front and probed around her vagina, telling me that there was nothing there.

“It’s not on the wall either. But, even after scooping this much out, nothing comes out, so I don’t think it came out inside.”

“I wonder. Maybe it got pushed in deep?”

“Doesn’t seem like it. Actually, it would be alright even if you came inside.”

At Yamamoto-san’s intriguing statement, just as I was about to ask what she meant,

“Ah……”

It was Yamamoto-san who first noticed the nature of the mishap.

“What’s wrong?”

“Well, for the time being, there’s no need to worry about pregnancy.”

Yamamoto-san fidgeted as she told me that fact, her back still turned to me,

“Sotomichi-kun, you might have cum in my butt.”

I couldn’t quite grasp the situation at this unexpected revelation. It seemed that in the heat of the climax, just the tip of my penis had entered Yamamoto-san’s anus. I had poured my semen in there.

Hearing that, I swallowed hard. If that was the case, if Yamamoto-san relaxed her butt, my semen should leak out from there.

“C-can I… confirm it?”

“Huh!? Eh, ahh, uu…”

Even Yamamoto-san, it seemed, wasn’t used to having her anus looked at. Even though only the tip entered a rather shallow part of the hole, I could even say that I had taken Yamamoto-san’s last remaining virginity. I had to check carefully.

“I-if that’s what Sotomichi-kun… says…”

Yamamoto-san’s face, carefully opening her butt with both hands, was redder than I had ever seen it.

It wasn’t that Yamamoto-san didn’t know shame, just that she was more comfortable with lewdness than others. Showing her legs was within the scope of what she considered expected. But this, truthfully, was an act tantamount to violation for Yamamoto-san.

“Is it… visible?”

In the center of her buttocks, slowly opened like drawing back a heavy door, was a chrysanthemum gate (twitching), trying to somehow hold back the overflowing semen.

“I can see it. I’ll clean it up with a wet wipe, so relax.”

“U, uuu… don’t… look so much…”

Finally resigned, the semen I had released inside trickled down from Yamamoto-san’s anus. As I felt moved by this sight, I carefully wiped Yamamoto-san’s butt until no more semen came out.

“I might seriously fall in love with Yamamoto-san.”

“I also like how your head goes dumb during that kind of lewdness, Sotomichi-kun.”

Yamamoto-san, still obedient despite having been humiliated, turned back to me and wiped my penis with a wet wipe.

“Um, Sotomichi-kun.”

There it was, still hard and erect. It couldn’t be helped after seeing something so erotic. It’s Yamamoto-san’s fault for being so erotic.

Just at that moment, the telephone rang, signaling the end of our time. If we left it like this, I would have to go home with another erection.

“Should we extend it for another thirty minutes?”

“That would be a big help.”

This time extension was a painful expense, but I couldn’t afford to care.

“Yes, yes… Eh? Ah, is that so. I understand.”

Yamamoto-san, who had answered the phone, widened her eyes and met my gaze. I wondered if it could be, and as it turned out, it seemed they were fully booked and couldn’t extend our time.

“What should we do? Should we have you cum one more time in the time we have left?”

“Well, that’s… a bit much.”

Considering how quickly I recovered, I didn’t think it would interfere with my date with Yuka if I got it out of my system here. But knowing that I was going on a date that would probably involve sex, further reducing my sperm count seemed too dismissive of Yuka.

“I’ll somehow calm it down.”

“Really? You don’t have to push yourself. You’ve finally been able to come again. And you’re probably still wanting to cum, that’s why you’re so big, right?”

Yamamoto-san, knowing my situation, was teasing me. What a wicked woman. I wanted to give her a proper punishment sex session someday.

“F-for now, should we get dressed?”

“Fufu. Yes.”

Seeing Yamamoto-san naked in a place like this made it difficult to calm down. While Yamamoto-san started putting on her bra, I wiped up all the mucus we had scattered around and cleaned the room as much as possible.

Depending on the circumstances, our voices might have leaked out while we were having sex. It was best to erase as much evidence as possible.

“Sotomichi-kun’s there, doesn’t look very swollen, does it?”

Yamamoto-san, dressed, murmured, casting her gaze down at my crotch. Certainly, the bulge wasn’t as noticeable as I had imagined. It seemed that thanks to my erection curving upwards, I was somehow managing to keep it contained within my pants.

“Wouldn’t it be alright if you hooked it with your belt?”

“I see.”

I loosened my belt by one notch, lowered my waist, and hooked my glans into the gap. Doing so allowed me to conceal my nearly vertical penis without my pants tenting.

“But this, walking with it is going to be painful.”

“It’s only until we get on the bus, can you manage somehow?”

“I’ll try my best, but it’s painful because it’s a sensitive area.”

If there were a mechanism to secure the shaft, there wouldn’t be a problem, but since I was hiding the most sensitive part, it was difficult to walk like this.

Moreover, I had to keep it in this fully erect state. It would be fine if it deflated all at once, but I would have to walk around outside with a semi-erection for a while. It would be one thing if only I were embarrassed, but Yamamoto-san, walking alongside me, would probably feel awkward too.

“If that’s the case, there’s only one thing to do.”

Yamamoto-san took out a hairpin from her pocket, and deliberately took off the pants she had just put on, dropping them to the floor.

“Don’t tell me, you’re planning on going home without panties…?”

“Wouldn’t that be more exciting?”

Certainly, if there was such an erotic girl next to me, my dick wouldn’t deflate and slip out from under the belt. To walk through the streets without panties for that purpose, how devoted was this person?

“After that, we just do this like this.”

Yamamoto-san also took off my pants, wrapped my stiffly erect penis with the pants she had just taken off, and secured it with a hairpin. Pale pink panties wrapped around my penis, and the gusshori (thoroughly soaked) wet crotch was guarding my glans.

“It looks extremely perverted…”

“Fufu. We’re a matching couple, aren’t we?”

When I re-tightened my belt in that state, I was now able to maintain my erection stably and without pain. One was in a skirt without panties, and the other was with women’s panties wrapped around his penis. We were a magnificent pervert couple.

After leaving the karaoke box, we paid the bill at the reception. Yamamoto-san and I held hands intimately and headed for the bus stop. When we got on the escalator, Yamamoto-san was strongly emphasizing that there weren’t many people around, so I was able to secretly fondle her inside her skirt. Even though it was obvious, the sensation of actually touching and feeling no fabric sent shivers down my spine. Touching her slit revealed a wet hole as a matter of course, and inserting my finger would allow easy penetration. It was a short escalator so I couldn’t do any more than that, but I could only imagine what would have happened if I had been giving Yamamoto-san a handjob, my semen would have soaked through Yamamoto-san’s panties.

In this way, we enjoyed sexual games that weren’t obvious to those around us as we made our way to the bus stop. Unlike before, it wasn’t late at night, so there were a fair number of people lined up, but it looked like we could somehow get a seat.

“Somehow, my bus memories with Sotomichi-kun are always filled with erotic things.”

With a skip that seemed almost literal, Yamamoto-san pulled me by the hand and sat in a seat on the bus that had arrived at the bus stop, her mood buoyant.

“I think it’s because you’re too lewd, Yamamoto-san.”

I placed my bag deep on my lap, hiding my erection from the boarding passengers behind us. We were in the safe zone now.

“I’ve never had sex like this with anyone I’ve dated. But, you’re having perverted sex with every girl you’re involved with. I wonder who’s at fault?”

“I have a small sample size…”

“Then, we’re even.”

“Let’s leave it at that.”

Having that exchange, Yamamoto-san rested her head on my shoulder. The bus started, and without voices on the bus, only the engine hummed a quiet time passed. I was completely off guard, thinking that today’s sex was over.

“A lot of people have gotten off.”

It was when the people sitting had stood up, and the shadows of people had thinned, that Yamamoto-san opened her mouth. Though my penis still retained a core hardness, it had settled to a semi-erection, and I thought it would subside completely before we got off the bus.

“The girl next to Sotomichi-kun, she’s not wearing panties right now.”

That single whisper in my ear fueled my cock with heat once more. Under that skirt was bare skin, wearing nothing. Even if it was summer, this girl was wearing too cool of an outfit, hiding it from the eyes of those around her.

“Yamamoto-san, you’re just too erotic for me to handle, you can’t go any further.”

“Can’t handle it?”

“I’m already horny.”

“Ehehe. Good for you for being honest.”

Yamamoto-san snuck her hand between my knees and my bag, and stroked my hardened cock.

“Sotomichi-kun, you can cum if Miyu-chan orders you to, right?”

Yamamoto-san had heard everything from Miyu about what kind of sex we had. That’s why she knew that my ejaculation could be controlled by Miyu’s orders. Recently, I’ve been asked to endure by my own will, but even now, if Miyu ordered me to ejaculate, I would, and if she ordered me not to, I wouldn’t come no matter how much stimulation I received. That’s just the kind of body I had.

“I wonder if it’s the same with me.”

I had found something close to Miyu in Yamamoto-san, and finally ejaculated without using Miyu as a okazu. If those conditions remained tied to my constitution, then I would also have my ejaculation controlled by Yamamoto-san. Though Miyu was more dominant, being ejaculation-managed by two girls was going to be a hellish situation someday.

“I… wonder?”

“Just earlier, you came right away when I told you to, didn’t you?”

During the sex at the karaoke box, I also ejaculated after hearing Yamamoto-san’s voice, “let it out.” It could have been just a coincidence in timing, but there was no doubt that my body was reacting to Yamamoto-san’s willful words.

“Sotomichi-kun, I wonder if you’d cum just from my voice even if I was the one doing it?”

It was the whisper of a demon. If Yamamoto-san definitively ordered me to ejaculate, then there was a chance that I would ejaculate right here.

“Even when I used to come with Miyu’s voice, I was in a pretty excited state, so I don’t think I’d come just from being ordered to.”

Even though I would ejaculate by Miyu’s orders, it was an extension of sex, and most of the time, the words were spoken in order to make me cum continuously. So, for example, just being told “dashite” in this situation wouldn’t be enough.

“Don’t you want to ejaculate into my panties like this?”

“Th-that’s…”

Yamamoto-san seemed determined to make me ejaculate with words alone, and even though I should be thinking of things that would deflate me and calm me down, my brain was being controlled by erotic fantasies every time I was provoked, and my mind felt like it was about to boil.

“Right now, you wouldn’t even get your suit dirty with semen.”

Now that I was wrapped in Yamamoto-san’s panties, it was close to being in a state of wearing a condom. Of course, Yamamoto-san’s panties would become sticky, and it wasn’t certain that semen wouldn’t drip out if I walked, but at least it was a much safer situation than ejaculating into my boxers.

“N-no, that’s no good, Yamamoto-san, today…”

“Sotomichi-kun. It’s best to cum when you want to cum.”

Yamamoto-san teased my dick like she was tickling a cat’s chin, using her index finger to flick it karikari. Each time, my dick twitched, and the pre-cum that leaked from the tip mixed with the love juice soaking the crotch of Yamamoto-san’s panties. Yamamoto-san’s underwear compressed my entire penis, and my glans felt the lewd moisture, further intensifying its hardness.

“Ah… No good… Not in a place like this…”

“It’s okay, Sotomichi-kun. Erotic is the same, even here. I want to become erotic together with Sotomichi-kun.”

In the corner of my vision, a single piece of cloth fluttered. It was Yamamoto-san’s delicate and fragile equipment, concealing her important part. If she lifted the hem a little, her striated skin tone would be revealed.

“Th-this is bad…”

I cautioned Yamamoto-san in a low voice, but my gaze was stolen by Yamamoto-san’s private area. In such a public place, still on the bus with passengers, she was exposing a part that should not be seen.

“Hey, Sotomichi-kun.”

Taking my hand, placing my fingers on her honey pot, Yamamoto-san pushed them firmly into that place filled with lewd fluid.

“I want you to release a lot of semen here, like you’re cumming inside me.”

Those words, whispered moistly, echoed deep within my ears. That voice pulled the trigger for my ejaculation.

“Ugh…”

Dokun, dokun, dokun, my throbbing cock quietly pulsed. From my glans to the base of my shaft, something warm flowed into that place where Yamamoto-san’s panties were 包んで(wrapping).

I had ejaculated. So easily. On Yamamoto-san’s orders, amidst this scene where I couldn’t be sure if I was being seen by ordinary passengers, I ejected semen like a pistol whose hammer was being dropped irrespective of the trigger being pulled.

I had decided that today would only be one time. Despite such a strong will, I had finally succumbed to Yamamoto-san’s temptation.

“You came a lot, didn’t you?”

How much semen I had ejaculated, Yamamoto-san shouldn’t have known. Even so, Yamamoto-san gently enveloped me, who was in a daze after ejaculating, and comforted me as if I was a child again. I was hopelessly no good. And yet, being spoiled by Yamamoto-san like that felt incredibly comfortable.

“Once we get off, let’s clean up and call it a day, okay?”

After that, Yamamoto-san and I got off together at the bus stop near the apartment. Since there were security cameras right after entering the entrance, I had Yamamoto-san take me to the post corner, where I took off my pants.

You might think we should just go inside since the room was right there, but if we went home, I would feel like I had to rest there for a while, and today was a day for having sex outside, no matter what, so I didn’t feel any strangeness about doing it here.

“It’s completely dirtied.”

Yamamoto-san lowered my pants and knelt down, taking the pants off. Yamamoto-san held on to the pants with one hand to keep the semen from dripping onto the floor, and brought her mouth close to my penis.

“I wonder if that underwear will be okay. Semen stains are hard to get out.”

“It’s okay, it’s okay. I’m used to washing clothes from when things have exploded by accident.”

For Yamamoto-san, it was a daily occurrence for a man to ejaculate while clothed. So, she probably didn’t think of this ejaculation as something special, as much as I did.

“I’ll clean it up.”

Cleaning up after sex. That was Yamamoto-san’s norm. Cleaning every last bit of me, from the base of my shaft to the gap around my glans, even the semen left in my urethra, was what this girl, Yamamoto-san, did. It would be strange not to fall for her after that.

“Okay, all done. I had fun having so much sex, Sotomichi-kun.”

“I somehow ended up enjoying myself too…”

According to Miyu, this was all proceeding as planned. I was actively reaching out to Yamamoto-san, and in doing so, our relationship was deepening again. What kind of solution lay ahead, I had no idea.

However, no matter what the circumstances, expressing personal gratitude was a separate matter. I had received so much fun and pleasurable sex, so I had to thank Yamamoto-san.

“Thank you, Yamamoto-san. That felt good.”

“You’re welcome. Thank you for the fun sex.”

My sex with Yamamoto-san had removed quite a few obstacles, both mentally and constitutionally. Most importantly, I was now ejaculation-managed by verbal commands. Even now that I had started using Yamamoto-san as an okazu to ejaculate, I could still enjoy sex as usual just by being told “be patient” by Yamamoto-san. This was a reality that was far too advantageous for Yamamoto-san.

“I want to have fun sex like this again sometime.”

“Ah, yeah, really, doing stuff like this with Yamamoto-san, I’m scared I might get hooked.”

Yamamoto-san’s pervertedness was a perfect match for my kinks. At home, for relaxed sex, it was best to have Miyu as my partner, but for sex outside, it seemed like I had better wavelengths with Yamamoto-san. Wavelengths that I definitely shouldn’t match with, though.

“I think it’s probably the same feeling as me being hooked on having sex with Sotomichi-kun.”

“This is a frightening thing.”

“Do you believe it’s your fault that I’ve become ecchi?”

“I’d say it’s probably half and half.”

If Yamamoto-san wasn’t an erotic girl at her core, I never would have developed into such a tormented being.

“You’ve become much more handsome than when we first spoke, Sotomichi-kun, so I was actually a little nervous too, you know?”

“Don’t be ridiculous.”

I didn’t know what kind of men she had dated in the past, but there should have been plenty of men who were more handsome than me.

“But, somehow I feel like I’ve been played by Miyu-chan.”

“Because your loved one was taken?”

“That’s… probably part of it. It’s me saying it myself, but I don’t think Sotomichi-kun would have become so good-looking if it wasn’t for the sex with me.”

I could mostly agree with the truth that Yamamoto-san had revealed. There were many things that I was able to move forward with because Yamamoto-san, who praised my strengths, was there.

“I don’t know how much of it was according to Miyu-chan’s plan, but as a result, I was just a woman who made Sotomichi-kun more of a man.”

It wasn’t a complaint or a grumble. She wasn’t speaking in such negative terms. It was just that she harbored a vague frustration, and I thought Yamamoto-san was also holding back feelings of discontent there.

“If Sotomichi-kun becomes such a good man because of that, it might be a little unfair.”

Finally, Yamamoto-san teased me with a slightly mischievous smile.

“I’ll return the favor.”

“Yeah. Sometime, during our long relationship.”

With that, today’s sex truly came to an end. Even Miyu probably didn’t have such a plan from the start. But, I thought those elements were also probably included in the reasons why she could allow me to have sex with other girls.

On the way home after parting with Yamamoto-san, Yamamoto-san’s words “sometime, during our long relationship,” for some reason caught in my mind, and I headed home with short steps, gazing at the completely darkened night sky.
