My Little Sister Is the Best F*p Material - Volume 1 Chapter 13.1: The fitting room is not a place for lewd activities."

Volume 1 Chapter 13.1: The fitting room is not a place for lewd activities.”

“To cut a long story short, you don’t know why you guys started dating.”

I was listening to Suzuhara’s account of how things unfolded as we entered the Japanese restaurant. Suzuhara had a chance to talk to Yamamoto-san right after advancing to the next grade, and when he boldly spoke about the allure of two-dimensional characters, Yamamoto-san showed interest. From there, the two of them had more opportunities to talk in secret, and eventually started going on dates, and before they knew it, they were in a relationship.

“But, Yamamoto-san doesn’t seem to like you very much.”

“Wh-what? Don’t say such things out of jealousy!”

Suzuhara got angry. But his bravado only lasted in the beginning. After taking a sip of water, he clammed up.

“It’s not like I’m jealous or anything. But, you know, when the four of us walked home together with Takanami the other day… didn’t you feel anything at all？”

At least to me, I couldn’t sense any affection from Yamamoto-san towards Suzuhara. She asked about Suzuhara’s past crush, tried to avoid him physically, and her face twisted in discomfort. There’s no doubt that she wants to break up with him.

“…Well, it’s true that we’ve been talking less recently. But I’m using all my time and money for Kanade, and I have no intention of contacting any other girls, and I’m even studying hard to catch up with her, and when we’re on dates, I carry her bags and make sure she doesn’t get tired, and I pay for all the meals, and I carry band-aids and sunscreen just in case, and I’m even thinking of taking on more part-time jobs to make things easier for her.”

“That’s scary.”

I understand that you want to cherish her, but even I can tell that you’re going overboard.

“What the hell? You’re talking like it’s a given that things aren’t going well between me and Kanade. Let me tell you, we’ve got a proper love life going on, you know.”

“Wh-what? You don’t have to go into such graphic details…”

“Oh? Is it too much for a virgin like you? I tried to tone it down for Kanade’s sake, but you better get used to it now. Sex with a woman usually starts with dirty talk.”

Suzuhara, with a smirk, poked at the breading of his cutlet with his chopsticks. It’s no wonder that this guy ended up graduating earlier than me, and on top of that, he’s with Yamamoto-san. It’s a double whammy of resentment.

“You’re doing it…?”

“Yeah, I am. The problem is that Kanade’s body feels so good that I can barely last for long even now.”

“Huh. Is that so?”

“But it’s not like I’m the only one. All the guys she’s been with before have said the same thing. It’s just that Kanade’s body is incredible.”

After Suzuhara started talking about dirty stuff, He became quite talkative. It was probably because he wanted to gloat over me, but it also seemed like he was trying to reassure himself after being denied so much.

“In any case, I’ve decided to dedicate my life to Kanade. No matter what she says, I’ll make it happen. That’s the kind of man I want to become.”

Even though I know she’s not into him, he can’t give up. It’s his first love, and on top of that, she’s an incredibly beautiful girl. Who wouldn’t feel the same way?

It’s a conversation that really takes away my appetite. I quickly finished my pork cutlet rice bowl and urged Suzuhara to leave the restaurant.

I should have been having dinner with Miyu right now. If Yamamoto-san had something to take care of, I could have understood it before, but now that she’s with Suzuhara, I can’t be so tolerant anymore. I won’t forget this grudge.

“Has Yamamoto-san contacted you yet?”

I was checking my phone to make sure there were no messages from Miyu. I really want to join up with her soon.

“On, you two. Are you done with your meal?”

Yamamoto-san, who was in a nearby store, came out. It just so happened that we finished our conversation at the same time.

“Oh, you got back early. How’s his little sister?”

“Well…”

Yamamoto-san pointed to Miyu, who was waiting quite far behind.

“It seems that Miyu-chan has something she wants to talk to you about, Suzuhara-kun.”

“Sotomichi’s little sister? What’s that about?”

What the hell is that? That bastard Suzuhara is even making a face like he doesn’t totally hate it.

“Well, I don’t know what she wants, but she’s your cute little sisterl, so I guess I’ll go along with it.”

“If you lay a finger on her, I’ll push you down the open staircase.”

“Wh-what? Don’t get so serious!”

Miyu will probably take care of herself, but if you so much as touch a single finger of her, I’ll cut off all your protrusions with a pair of pliers.

“……You really care about Miyu-chan, don’t you, Sotomichi-kun?”

Suzuhara went over to Miyu, and now it was just Yamamoto-san and me. After hearing that unpleasant conversation, I wasn’t sure if I could talk to her the same way as before. Yamamoto-san seemed to sense my negative emotions, and bowed her head with her hands clasped in front of her.

“Once again, I’m sorry.”

Yamamoto-san, with her adorable body language, was twisting her body. Her beauty as a woman was packed into every inch of her body, and now that I think about it, it was a mistake to think that Yamamoto-san didn’t have a boyfriend.

“You have nothing to apologize for. Just that, I don’t really understand what you wanted. I thought you started talking to me because you wanted to break up with Suzuhara.”

I asked in a somewhat careless tone. Yamamoto-san nodded while playing with the ends of her hair, looking uncomfortable.

“That’s right. I do want to break up with him. And I started talking to you, Sotomichi-kun, because I wanted your help with that. So, I’m really sorry.”

Yamamoto-san bowed her head deeply once again.

The epitome of an evil woman, I suppose. It seems that Suzuhara confessed first, but if she accepted, she should have had a little more sense of responsibility, shouldn’t she?

“But, as for that, it seems like it’s going to be resolved. I was thinking that we could get along better, Sotomichi-kun.”

“Resolved? You mean break up?”

“Yeah.”

“I see…”

Based on Suzuhara’s attitude, I don’t think it’s going to be that easy to break up with him. But what does she mean by “resolved”? Is Miyu doing something behind the scenes?

“To be honest, it’s complicated. Suzuhara-kun is a good guy, after all. Even if he’s going a bit overboard, he’s still trying hard, and I think he deserves to be cherished more.”

You’ve only been together for a month. It’s way too short to make a judgment.

“…I can’t really go into details, but there were conditions for us to start dating.”

Is that so? Suzuhara didn’t mention anything like that.

“Those promises have already been broken.”

“Eh??”

“But if we break up, He said he’ll tell everyone about my problems”

“Oh my…”

Suzuhara, talking about love and all that… I’ll remember this when you get back.

“To be honest, I’m a bit tired now. I wish I could have explained myself better.”

Yamamoto-san’s face was exactly as exhausted as her words suggested. According to her, half of what we messed around with was out of sheer desperation.”

“By the way, what were those conditions?”

“Umm, I guess I could tell you, Sotomichi-kun.”

Why is it okay for me?

“Miyu-chan said it would take a while. Why don’t we go around the stores?”

Yamamoto-san was trying to invite me with a forced smile. I tried to show that I was also tired by lifting the bags I was carrying in both hands, but Yamamoto-san still wanted to take me with her.

“Mmm. You don’t have to be so resistant.”

“I’m not resisting. I’m just confused by the lack of context.”

I understood Yamamoto-san’s circumstances. It’s not like I started hating her or anything. But from earlier, the way she kept rubbing her fingers against my hand, sighing over and over, and acting so blatantly suspicious while trying to invite me—his behavior was just too questionable.

“Are you hiding something?”

“…No, I’m not.”

“You’re a terrible liar.”

Since it’s clear that she’s hiding something, I don’t feel like I can comply until I hear what it is. Yamamoto-san seemed to sense my resolve, took a deep breath, and then let her shoulders drop.

“I understand.”

It seems that my persistent stare worked. Since experiencing Miyu’s silent pressure, I’ve been gradually learning how to use it.

“I was asked by Miyu-chan to go around the ladies’ shops with you, Sotomichi-kun.”

“Eh…? Why?”

“She said it’s good for you to know a little about girls’ clothes. Miyu-chan had a hand in your change, huh? That’s why your atmosphere has changed so much.”

Yamamoto-san leaned in, peering into my face. That kind of gesture—whether expected or not—still got to me. Her features were truly well-crafted. Those moist eyes, those lips, they were so perfectly shaped it was as if they had been sculpted by human hands. If you were dating someone like this, of course, you wouldn’t want to let them go.

“W-Who knows…?”

“I understand. Let’s go.”

It’s Miyu’s command, after all. Apparently, Yamamoto-san had exchanged contact information with Miyu when they were alone together. And now, it was confirmed—she was trying to drag me around at Miyu’s request. Or rather, it was more of a command than a request.

“Oh, yeah, that’s right. You’re coming with me, right? That’s right…”

Yamamoto-san suddenly became fidgety. Why are you acting like that when I already agreed?

“Okay, I’ll put my heart into it.”

“Y-Yeah?”

From there, Yamamoto-san suddenly stopped talking. Her movements were also awkward, and she didn’t even pick up any clothes when we entered the store, and after walking around in a circle, she left the store.

“There’s a large store on the upper floor, right? Let’s go there.”

“That cheap place? I’ve already been there… Oh, but I guess I haven’t been there for ladies’ clothes.”

It was the largest clothing store in the shopping mall. It has chain stores all over Japan, and there’s probably no one who doesn’t know about it.

“Maximum of five items for fitting… Will that be enough…?”

As soon as we entered the store, Yamamoto-san checked the fitting room limit. She’s checking such a thing before even looking at the clothes? Hmm, I’m learning something new.

“Clothes with lots of buttons… Clothes with lots of buttons… Should I bring my underwear too…”

Yamamoto-san mumbled as she moved through the store. It’s a bit more than a little creepy. I thought she would shop more elegantly, so it’s a bit unexpected.

“Okay, I think this is good.”

Yamamoto-san picked out some clothes and headed for the fitting room. Is my role over now?

What was I supposed to learn? That we’ll be changing stores a lot more than I thought? Do I have to somehow incorporate this into our date? This is difficult.

“Sotomichi-kun, could you come with me?”

“Me too? Into the fitting room?”

“I want you to see if it suits me.”

“If that’s the case, then sure. I guess it’s okay.”

Is it generally the case that men decide on such things? If so, it might be a problem that I don’t know much about ladies’ clothes. But a man who knows a lot about women’s clothes would be weird, wouldn’t he?

“When I say come in, please come in as soon as possible without opening the curtain too much.”

Yamamoto-san put the basket inside the fitting room, turned to me, and confirmed that I understood.

“Understood.”

I put my luggage in front of the fitting room. In a place that doesn’t get in the way of passers-by and doesn’t interfere with the opening and closing of the curtain.

“Haa. Fuu…”

Yamamoto-san was reluctant to enter the private room. She repeated deep breaths, as if she were about to hyperventilate, and seemed to be waiting for some kind of timing.

“Okay…”

She finally made up her mind and went into the private room. She seemed to be taking deep breaths again inside, where the curtain was closed.

Is showing off new clothes really that embarrassing? And insisting on keeping the curtain as closed as possible… Even though all the staff managing the fitting rooms are women. Girls are complicated.

Even through the curtain, I could hear the sound of clothes rubbing against each other. Indeed, it does create a strange atmosphere when there is a partition like this. I’m getting nervous too.

“…You can come in now.”

Yamamoto-san’s tension was transmitted to me, and my hands, which were holding the curtain, began to tremble. Is dating a girl this stressful for your heart?

As instructed, I opened a minimum gap through which I could pass, and entered the private room.

“Excuse m—!?”

Then, I was speechless.

“Hurry up and close it.”

Yamamoto-san, hugging her own body, urged me to hurry.

In my confused mind, I persistently checked that there were no gaps in the curtain. And then, as I finally began to process the incomprehensible sight before me, my thoughts slowly started to catch up.

“Yamamoto-san, your clothes…”

Nude all over. It was too bold to be called fashion.

…Or rather, she was completely exposed. Yamamoto-san wasn’t wearing any underwear at all.

“I don’t really understand the situation…”

Yamamoto-san, without hesitation, slowly closed the gap between us. Since the width between us was less than a meter from the beginning, Yamamoto-san easily pushed me against the wall with just a few steps.

“Don’t think about anything. Just feel it.”

“Umm… Wait…”

Yamamoto-san hugged me as it was. Then, she put her hand on the back of my pants and pressed her lower abdomen against my crotch.

It’s completely different from what I felt at school. The sensation of being hugged by a real naked body, even through my clothes, was clearly conveyed.

“Why… Why are you doing this…!”

My T-shirt was pressed against Yamamoto-san’s breasts, and my exposed abdomen directly felt the soft skin of a girl. It was an unprecedented pleasure for me.

“I’m sorry, Sotomichi-kun. I sold my soul to the devil. That’s why I can’t do anything but this.”

“Devil… What?”

“It’s Miyu-chan…”

Yamamoto-san filled her eyes with tears.

So that’s what it is. Miyu’s true purpose was this all along.

The reason why I’m in this kind of clothing store in the first place is because I can’t get it up with any other girl besides Miyu. Yamamoto-san was asked not to teach me about fashion, but to sexually stimulate me and make me erect.

“How far were you told to go?”

“I just have to send a photo of Sotomichi-kun’s erection.”

A photo. My psychological threshold is quite high, but I guess I have no choice but to do it.

“Anyway, Sotomichi-kun, you should take off your clothes too.”

Yamamoto-san unzipped my pants, unfastened the waistband button, and slid them down along with my underwear. The way she did it so effortlessly made me wonder—am I the one with a dirty mind for noticing?

“Uuu… Why isn’t it getting bigger…”

“This is partly out of nervousness.”

Yamamoto-san became even more teary-eyed at my half-hard penis. She probably wanted to take a picture and be done with it, but I also need some time to get used to the atmosphere when it’s so sudden like this.

There’s no way I’m so far gone that I can’t get it up after all this. At least, I really hope that’s not the case.

“Now that it came to this. The best stimulation for boys are boobs, isn’t it?”

In a kneeling position, Yamamoto-san lifted the part of her body closest to my penis. Yamamoto-san’s hands should be big, but she pressed her breasts, which overflowed from her fingertips, against my penis.

I couldn’t feel much elasticity because it wasn’t fully erect, but the high body temperature accumulated in the cleavage and the image of my penis being sandwiched between her breasts alone sent nerve pulses to my sexual excitement area in my brain.

A body with flawless skin all over. The tips of her breasts were so pale that no one would think she had been used by countless men. Just by looking at the outside, no one would think that Yamamoto-san was such a sexy woman. But in a way, I can’t help but think that this body was born for sexy things.

“How about it? Should I give you a blowjob?”

Such words came out of her so casually. A blowjob is something I’ve asked Miyu countless times, but she’s never done it for me. There was no reason for her to refuse, was there?

“Oh, but it’s getting bigger.”

Yamamoto-san noticed that my penis, which had been flaccid, had become a proud erection. The sensation of my penis being sandwiched between her breasts for the first time seemed to have finally awakened my little soldier.

“Umm… Shouldn’t you take a picture of this now…?”

“Hmm. Hehe. I wonder. Should I do it before taking the picture?”

My heart was torn as I was asked again. I was probably hesitating because of all the things with Suzuhara. But with Yamamoto-san as my partner, I had no reason to refuse.

“Excuse me, customer. How is the size?”

When the staff called out to us, we jumped.

That’s right. This is the fitting room. If we use it for too long, we’ll be suspected.

“I’m sorry, I’m trying out various combinations, so please wait a little longer.”

“Oh, no, it’s fine. I just came to tell you that if it doesn’t fit, we’ll bring ones that will do to you. Please take your time.”

A conversation through the curtain. Yamamoto-san was naked in the middle of changing, and I was exposing my lower half without even bringing any clothes. If they had seen inside, it would have been me who was in trouble.

“Well, what should we do?”

Yamamoto-san asked my little soldier, which was still in good condition.

“I think it’s better you take a picture.”

“Yeah, you’re right. I understand.”

Yamamoto-san took out her smartphone from her pouch and pointed the camera at my crotch. It was incredibly embarrassing, but since it was Miyu’s command, I had no choice but to obey.

“Sending it… Oh, I got the okay. Yay!”

It seems that Yamamoto-san’s mission is complete.

“It seems like Miyu-chan is coming. Can I go home?”

“Umm, yeah, sure.”

Yamamoto-san started getting dressed with a refreshed look. It’s not like we’re following a flow anymore. I guess there’s nothing I can do. I’ll put on my pants too, just in case.

“I’ll leave the clothes in the basket. Miyu-chan said she’ll come here directly.”

“Okay.”

Yamamoto-san put her arm through the bra and skillfully held her breasts while fastening the hook with one hand. It was a quick movement, but it was probably something that required a lot of grip strength.

I was just going with the flow. Only the bulge in my crotch was claiming its existence in vain.

Yamamoto-san stood up, put on her pants, and then the sound of the rubber band tightening. Yamamoto-san, in her underwear, looked at me and blushed.

I’m staring at her, but it’s okay, right? Her body is really sexy. Miyu’s sexiness comes from her overall atmosphere, but Yamamoto-san’s is in the shape of her body itself.

“It seems like Miyu-chan took care of things with Suzuhara-kun. I’m going to go get dumped now.”

After putting on her clothes, Yamamoto-san put her hand on the curtain. She smiled and left the fitting room.
