My Little Sister Is the Best F*p Material - Volume 1 Chapter 13.2:

Volume 1 Chapter 13.2:

Then, a few minutes passed. With women’s underwear and my erect penis that wouldn’t go down, I started to feel a sense of crisis that if the staff saw inside, I would be socially finished. Just when I was beginning to feel that way, the savior finally appeared.

“Onii-chan.”

She peeked her face through the curtain. Before I could even call out to her, she opened it. I instinctively braced myself, but there was the familiar and reassuring face I was used to seeing.

“How was it with Yamamoto-san?”

Miyu took off her shoes and came inside.

“Well, as you can see.”

I showed off my fully erect penis to Miyu. Her reaction to it was just a blink of an eye.

“It’s not me, is it?”

“This is different.”

I can understand why you would want to doubt it. But this was definitely an erection caused by my excitement for Yamamoto-san.

“Well, about that…”

“Hmm?”

“I might be able to cum just by thinking about Yamamoto-san.”

“Is that so?”

Miyu rummaged through the basket that Yamamoto-san brought while giving a careless reply.

“Can I ask you something?”

It was my selfish request for her to let me ejaculate right there.

Miyu picked up the bra from the basket, checked the cup size, and then came in front of me, saying, “Okay, okay,” and sat down in seiza.

“Please.”

Miyu was in the same place where Yamamoto-san had been a moment ago. Long black hair, big eyes, and a big chest. The difference was in physique and charm.

Other guys might say that Yamamoto-san is better in every way, but to me, Miyu is superior in every aspect. As for charm, I’m a contrarian, so I prefer the winner to be the one with less charm.

“Can I ask you for one favor?”

“What is it?”

I made a request to the businesslike Miyu. I wanted her to take off my pants with her hands, just like Yamamoto-san did. I sent that wish through my gaze.

“Do it yourself.”

“Okay.”

I was instantly rejected. I feel like she’s been more unfriendly and even more domineering lately.

I reluctantly took off my pants and lowered my underwear. My erection, which had sprung out due to the momentum, was less energetic than a few minutes ago.

Naked from the waist down, me, and my sister trying to take the release into her mouth. The excitement of us doing perverted things doubled because of the mirror next to us.

Maybe I get more turned on when a girl is dressed. When I was sandwiched between Yamamoto-san’s breasts, I was at my peak, but now, seeing the cleavage of my little sister’s breasts properly shaped by the bra, I’m even more excited.

“Onii-chan.”

It was a warning tone. I was scolded for staring at Miyu’s body.

“Oh, no, this is because just a moment ago, You were in the same position as Yamamoto-san.”

“Is that so?”

“Yeah.”

“Then it’s fine.”

Her intuition is sharp, but she’s the type who  doesn’t trust it, huh? Well, I’m going to use Yamamoto-san as my masturbation material too anyway.

But Miyu is just too sexy. I can’t help it. Should I close my eyes?

I tried to grab my penis first. It was the place where Yamamoto-san’s breasts had been just a moment ago. With my size, it would have fit perfectly. I wonder if it would have felt good if I had been stroking it like that. I especially wanted to get a blowjob.

“Umm… Ah… I might really be able to cum.”

The male organ is also the place where you urinate at the same time. Having a girl lick that must feel incredibly good. To be honest, I’m more interested in getting a blowjob than losing my virginity.

I should have made her give me a blowjob by force. Yamamoto-san seems like she would be really good at it. I think she would have swallowed my cum if I had come in her mouth.

Miyu is basically off-limits to touching, and I don’t hate that she’s so firm in that regard.

I stroked my erect penis hard. Miyu was just watching it.

Miyu’s breasts, which clearly shaped her T-shirt, were firmly packed by the bra. Her body is small, so she won’t be that good at giving a titjob, but in the deepest part, even Miyu can probably wrap her breasts around my penis.

I’d be okay with a titjob from Miyu. Actually, if she did any kind of service with her body, I feel like I could cum forever.

Those cold eyes of hers watching my masturbation. If she gave me a handjob with that face, I’d cum three times as much. I don’t need her to use her sticky fingers or dirty talk. I just want her to process my sexual desire roughly.

“……This is aad…!!!”

I was thinking about Miyu, and my switch for ejaculation was about to turn on.

No, this will make it seem like I’m masturbating with Miyu as my material.

“About to cum? Hmm…”

Miyu opened her mouth and came closer. It’s no good. I want to cum. I want to cum in this state of ejaculation and make Miyu disgusted with the amount of cum I shoot out and swallow.

“Miyu…”

“Excuse me. Customer? Are you okay?”

The staff called out to us again, and Miyu also panicked and squeezed the base of my penis tightly.

But the ejaculation switch had already been turned on. I shook my head at Miyu to let her know that I couldn’t stop it.

Suddenly, the edge of the curtain moved slightly.

The staff probably wouldn’t try to peek inside without permission, but considering the long usage time and the fact that I had left my luggage outside, they might check if anyone was there.

Fearing that, Miyu instinctively pressed the edge of the curtain. If we didn’t answer quickly, the staff would become even more suspicious. And I, as a man, couldn’t answer either.

There was no choice but for Miyu to respond to the staff’s call.

“I’m sorry. It’s taking a long time to get dressed. I’ll be out soon.”

Miyu’s mouth, which was supposed to receive my cum, was taken away to deal with the staff. Instead, Miyu’s chest, which was held by her other arm, was now sandwiching my glans.

“Ahh–!!”

With a sensation close to urination, my cum was poured into Miyu’s chest. The white liquid, which was initially invisible due to the thick chest, was pushed out into her cleavage, gushing out, and accumulating in the groove.

“I’m sorry for the inconvenience. It’s a rule for us to confirm.”

“I’m the one who should apologize for causing you worry.”

Even in such a situation, Miyu pretended to be calm and responded to the staff. Meanwhile, I kept ejaculating into Miyu’s chest.

By the time the pulsation of my penis ended and it settled down, an obscene lake had formed in Miyu’s cleavage. After finishing the conversation with the staff, Miyu let go of the curtain, and my penis slipped out of the cleavage.

I had finally ejaculated. On Miyu’s body, which was still dressed.

That sight was seared into my brain vividly. The desire to ejaculate didn’t subside even after I had cum.

There was silence for a while. Miyu closed her eyes and calmed her breathing slowly. One arm was still tightly hugging her chest. If she relaxed her grip, the cum would probably drip down to her stomach.

“Umm… I’ll wipe it for you now…”

I took out tissues from Miyu’s bag and took out all of them from the bag. Miyu hates having her clothes dirty, so if she were to get cum on her chest while dressed, she wouldn’t be able to stay calm.

I want to wipe it off quickly. But I’m still hesitant to touch her body.

While I was thinking like that, Miyu sighed deeply and finally raised her face.

“Take care of the top first.”

Miyu opened her mouth and her eyes at the same time.

Her eyes and cheeks were slightly red.

I couldn’t suppress my anxiety and quickly applied the paper.

“The top’s done. Put it in the lower part too.”

Miyu gave instructions in a flat tone. Lower means from the stomach side, right? I don’t have time to hesitate. Even if this leads to us breaking up, I’ll do my best.

“I’ll put it in.”

I started to put paper between Miyu’s lower breasts. Fortunately, it didn’t seem to have dripped down to her stomach, and there was no sign of cum on her shirt either. …Except for the bra, which had a stain where my cum had leaked from the cleavage because there was too much of it.

“Yeah. Thank you.”

Miyu confirmed that the cum was sufficiently absorbed and released her chest, which she had been holding tightly. Why did she say thank you? Was it a hint of farewell?

“Aren’t you angry?”

Miyu, who had her hands free and started wiping her body herself, was maintaining her composure.

“I’m angry about five hundred times more than you can imagine.”

She was really angry. What should I do now? My cheap apology won’t be enough to settle this.

“But I can’t really blame you either. I’m trying not to get angry.”

Miyu didn’t show any hostility at all. I wish she would just show her true emotions openly.

“I also agreed to it. The direct cause was an accident because the staff came. And it was my decision to catch it with my chest. So it’s not really your fault.”

Miyu finished wiping her body and repacked the bag she got when she bought the clothes, putting the extra ones in it.

“It might be true logically, but I think it’s my fault. Anyone would think that you should be the one to get angry at me.”

“Maybe so.”

“What’s your true feeling, Miyu?”

“I want to punch you.”

“I expected that.”

That’s right. That’s the right emotion, my sister.

“So, for the sake of both of us, I want you to punish me.”

“I understand.”

Her judgment was quick.

“In that case, take it off.”

That command also feels like I’ve heard it a lot lately. I pointed to my underwear to confirm if that’s what she meant, and Miyu nodded vigorously. And so, I performed my third public stripping of the day. There was a penis hanging down, with some hardness left.

“Cover your mouth. As hard as you can. Make sure no sound comes out.”

“Ugh… O… Okay…”

I sense that something incredibly scary is about to happen. But I must not resist. I must not hesitate. I must obey whatever she says. I covered my mouth with both hands as Miyu told me to. Now, I’m ready.

“I’ll do it hard.”

Miyu got on her knees and grabbed my waist.

My penis, which was terrified, was regaining its hardness.

What’s going on with my brain?

“How dare you do that… to my body…”

Miyu opened her mouth wide and swallowed my penis up to the base of the glans, and then.

“Ughhhhh!!”

I tried my best to suppress the screams.

It felt like half of my penis was burning. I could even hear the sound of the fibers tearing, “bichi-bichi.” The sensation of my urethra being crushed reached me, and it was no longer an image, just pure pain that was real.

“Ngggggg!!”

Miyu was biting my penis hard, with an incredible amount of hatred. Oh no, oh no, oh no, I’m going to die. My knees started shaking. My eyes were flickering. I was gone…

“Phew!”

Miyu’s mouth, or rather, my penis, which should have been released from her teeth, continued to inflict severe pain on me with each twitch, as the bite marks spread.

“Aaahhhh… Kuu…”

I collapsed, my hands on the ground. I was shedding tears and laughter at the same time, at a pain I would never experience again in my life.

I am definitely not a masochist. The fact that Miyu was able to express this much anger towards me means that there is still room for us to repair our relationship. That was what made me so happy, no matter what.

“Well, I’ll take this basket and go home first. Don’t forget the things you bought.”

Miyu quickly opened the curtain halfway, put on her shoes, and left. I was struggling with my tightened diaphragm.

“Umm, I’ll just ask you this once. Are you okay?”

Miyu sounded guilty. I couldn’t respond with my voice, so I gave her a thumbs-up, and she quickly closed the curtain and left.

“Aaaah…”

With no one watching, my energy depleted, I leaned against the wall, exhaling like a broken machine. The pain was so intense that it made all the shocks I experienced that day seem insignificant.
