My Little Sister Is the Best F*p Material - Volume 2 Chapter 10: My Little Sister and The Bath

Volume 2 Chapter 10: My Little Sister and The Bath

Miyu and I straddled the toilet seat, pressing our bodies against each other. My penis was being pressed against Miyu’s stomach, and it seemed that Miyu was feeling every movement of my penis, which was twitching.

“Onii-chan… no… don’t… don’t cum…”

Her voice was desperate, and her moist gaze was raised to me, and my desire to ejaculate grew even more. The muscle contraction of my penis was something that led to ejaculation, and Miyu already knew that. If I ejaculated as it was, Miyu’s T-shirt and skirt would be covered in semen. Miyu, who hates having her clothes dirtied more than having it on her body, would not forgive me if I did that.

But my ejaculation had already reached a point where I couldn’t cancel it. It was like holding a cup filled to the brim with water in one hand. I could hold it for a while, but I couldn’t keep it from spilling.

Even so, Miyu hugged my body with all her might. Her high breasts were crushed, and even through her bra, I could feel the softness. Her breasts were too big, and even a slight lean didn’t fill the space in her lower body.

Miyu, who was holding my arm, was breathing roughly. She seemed to have no choice but to pee right there, even though she was trying to hold it in until she couldn’t stop herself.

“Don’t twitch… Uuuh…”

If I ejaculated, I would feel relieved. Miyu, who didn’t stop resisting until the very end, was suffering because I was twitching my penis. It was probably stimulating her bladder. I wasn’t doing it on purpose. Just like a hiccup, if you stop it to a certain extent, you can’t help but twitch. And yet,

“Au… No… Stop…”

It was as if I was forcing Miyu to pee. The humiliating sight of her sister, who was suffering from the limit of her urination, and didn’t want anyone to see. I was stimulating her bladder and urging her to urinate.

Oh, this is dangerous. I’m so excited.

“Ah… Ah…”

Eventually, the strength of Miyu’s grip on my arm weakened. The transverse muscles, which had been listening to Miyu’s desperate wish, seemed to have finally given up their role.

The tension in the muscles of her face also relaxed, and Miyu’s eyes, which were exhaling “haa,” were somehow unfocused. Finally, Miyu looked up and stretched out her arms while looking at something behind me.

“Semen, don’t release it, okay? Onii-chan.”

Miyu said that with a drained face, and then covered my ears with her fingers. The sound of the air being closed inside my ears echoed. Miyu, who was blushing with her face down, and I realized my own limits while witnessing that moment.

Even though she was trying to kill the momentum, the sound of it hitting the surface of the water could be heard even through my fingers that were covering my ears. The faint scent of acid passing through my nose inevitably told me the fact.

Miyu was peeing. In front of me. With her body pressed against mine, and one leg raised. How much humiliation was she hiding behind that expressionless face? Seeing that figure, I ejaculated. I ejaculated semen into Miyu’s T-shirt, again and again.

I couldn’t say the words of apology. It was too good, and I was about to moan.

Miyu’s expression remained blank. Even though her clothes must have been in a terrible state. Even though I couldn’t see the ejaculation hole, the slimy feeling of the semen passing through the urethra and the tightness of the penis at the time of ejaculation told me that it was definitely the largest ejaculation volume ever.

Even after my ejaculation, Miyu’s urination continued. My ears were still covered, and I could feel the hot body temperature from Miyu’s hand. Because she was suppressing the momentum of the discharge, Miyu continued to pee for almost a minute. The length, volume, and smell of it all were tormenting Miyu with shame. Semen was dripping all over her stomach, which had been directly sprayed by me, and it was a mess that could be called rape.

Even after we both finished releasing what we had to, the two of us were silent. We didn’t move a muscle, and we were frozen for about five minutes. Eventually, my ears were released from Miyu’s fingers. My penis was still hard.

“Onii-chan.”

It was a deep voice. Miyu put her hands inside her clothes and slightly frowned. There was semen dripping between her fingers, and it was visible that there was a lot of semen on her hand.

“Miyu… I’m sorry… I…”

I couldn’t hold back. I occupied the toilet for masturbation. I made her fall by stepping on her pants. I ejaculated in front of my sister, who was experiencing the humiliation of being observed while urinating. Miyu, who even cherished her clothes the most, I had dirtied them with semen. There was no excuse. I wanted to apologize, but I didn’t know how to apologize.

“There’s a lot of it.”

Miyu kneaded the semen that was attached to her hands with a “Goo-per.” Her eyes were still without the iris.

“Why couldn’t you hold back?”

Miyu checked the stain on her clothes, took off her T-shirt, and took off her skirt like trash, pulling the rubber waist to the limit.

“If you like it that much, you should just cum.”

Miyu, who was now wearing only a bra, grabbed my penis, which was still erect, with her semen-covered hand.

“Mi… Miyu… Ah… Ah, ah…”

Miyu, with her small hand, which was too small for my penis size, slid from the base to the tip of the glans, entwining the semen.

“Ah… Guh… Miyu… Ahhh…”

The temperature of Miyu’s body was transmitted from the entire palm of her hand to my penis, and her fingertips surely captured the pleasure spot. Was it because I was a man who could only cum with Miyu? Or was it because it was the opposite of what Sachiko did to me? Even though it was a rough handjob, my body accepted it as the ultimate pleasure. Miyu was supposed to be touching a man’s thing for the first time, but her handling was already giving me pleasure several times that of masturbation.

“Haa… Ah… I… Ah… Again… I’m gonna cum…”

She was attacking the erogenous zones that I wanted to be stimulated, point-blank. With that technique, I ejaculated for the second time without even noticing it. After ejaculating, semen overflowed like magma from a crater, and the amount of slime that slid my penis increased even more.

“Ah, ahh!! Miyu! I’m already… I’m already cumming…!!”

Even after I ejaculated, Miyu didn’t stop her hand. Rather, she caught my retreating waist and now she was wrapping both hands around my penis.

“Aaah, agh… Uuuh… I’m cumming… Aaahhh…”

With each hand, she was playing with the glans and the frenulum, and sometimes she rubbed from the base of the penis to the surface of the scrotum, massaging the testicles. The pain was only at the beginning. Only pleasure substances were overflowing in my brain. The third ejaculation was already approaching.

“Why… why is this happening… Haa… Aaahhh… It feels… good…”

My muscles were so relaxed that I was drooling. My head was white, as if all the nerves that transmitted sexual sensation had been cut off. Along with the pain, various functions were paralyzed. My penis was just delighted to be played with by Miyu, drowning in pleasure.

“How many times do you think I’ve seen you, Onii-chan, masturbate?”

The grip that rubbed my penis was getting stronger. The force that was squeezing it with anger was just balanced with the force I would use as a man.

“It feels good, right? You can still cum, right?”

Threatened with a blank gaze, I couldn’t even hold back a little, and I ejaculated for the third time. Despite the considerable amount of semen I ejaculated in the first ejaculation, the amount that came out this time was unimaginable.

Miyu’s hand didn’t stop.

“Aaah… Aaahh… Haaahh… Miyu… No… Forgive me… Aaahh…”

Even when I begged, there was no sign that Miyu would stop her handjob. If I pushed her away by force, it would be over. But I couldn’t move. My brain was dominated by the sense of guilt towards Miyu and the endless pleasure that was given to me.

“Even though you’re ejaculating so much, you’re still hard. It means you want to ejaculate. It’s okay. I’ll make you ejaculate as many times as you want. Cum as much as you want with your sister.”

Miyu’s handjob gradually focused on the glans. It was a handjob that followed ejaculation after ejaculation. Miyu had no intention of stopping until she made me squirt.

“Aaahh!! Iii, Iiiii… Aaahhh… Aaahhhhhhhhhh!!”

From the urethra to the glans, there was only pain. The handjob punishment by Miyu, which I had to accept, even made my brain, which was supposed to block the pain, submit to Miyu and start flowing pulses. Agony, screaming in pain. There was no pleasure, yet there was certainly pleasure in it.

“Ah, haa… I’m gonna die… I’m gonna die…!!”

The pain was pleasant. It wasn’t that the pain was being converted into pleasure. My brain was rejoicing in being tormented. I had reached a realm that I should not have entered. My body was arched, and I think I was probably even rolling my eyes at that time.

“Uaaah, fuuaaaahhh, I’m gonna cum! Ya, it’s dangerous… I’m gonna die… I’m gonna cum… Aaahhhhhhhhhh!!”

I, who was supposed to be inexperienced in squirting, was developed from the tip of my penis to the depths of my testicles by Miyu’s first handjob, and I ejaculated like in an erotic game. The muscle contraction of my penis, which was convulsing, didn’t stop, and semen flew out with each contraction. Even in the middle of ejaculating vigorously, Miyu didn’t stop her hand. Rather, the stroke became even more intense, urging me to ejaculate.

“Aaah… Ah…!!”

Semen was flying all over the place. It was also on Miyu’s bra and cheeks. Even so, Miyu didn’t stop her hand. Ejaculating, ejaculating, and finally, after ejaculating dozens of times in just a few minutes, the squirting finally stopped.

I was dazed like a zombie, and I was stunned, even though I hit my head on the toilet faucet. My penis was in a state of rigor mortis. The magazine was already empty, yet the ejection port was firmly fixed, and it was still erect.

Miyu started rubbing that penis with both hands.

“Aaah!! It, it hurts! It hurts, it hurts, it hurts! Miyu, stop, stop…!!”

It was as if the skin was rotting and blood was about to come out. The hot, piercing pain was like the sensation of being burned with a lighter.

“Because you’re erect. I don’t want to, but I’ll try a little harder. Onii-chan, try to cum too. … Otherwise, it won’t end.”

Miyu didn’t stop her hand. After the pleasure attack, what began was torture. In Miyu’s words, which mentioned that “it won’t end,” there was a clear intention to kill me, who was such an incompetent brother, by not letting me finish ejaculating until I died.

“Miyu… Miyu… AAhhh… Please…. Forgive meee…. Ah ah ah ah…”

No matter how much I begged, Miyu didn’t stop her hand. The pain that had been taken on by my brain alone until then was now distributed throughout my body. My muscles tensed, my teeth chattered, and my internal organs were squeezed. Eventually, my body became floating, and it was as if I was in a different world.

If I ejaculated in this state, I would really die of abdominal pain. I would die an untimely death, angered by my sister and stroked by her hand. It was my fault that I ejaculated and still got an erection from my sister’s handjob. Thinking so, I instinctively realized that I couldn’t stop getting an erection, and I lost my voice along with that despair.

“Your little sister helped you cum.. Onii-chan is so happy, right?”

Miyu caught me, who was collapsing, on her shoulder. I couldn’t even speak anymore. The sound of Miyu’s handjob, “Gucha, gucha,” was melting into the silence of the toilet. Somehow, the pain had disappeared. It was as if my lower body from the neck down had been cut off, and I felt nothing. Or maybe I was already dead.

“Onii-chan. Cum.”

Ordered by Miyu, I felt only my lower abdomen. There was a pain as if a crack had entered the rod, which was exhausted by repeated ejaculation, and the urethra was worn out, and I couldn’t feel pleasure anymore. Still, I reacted only to Miyu’s voice, and ejaculated. An adequate amount of semen, equivalent to one ejaculation, landed on Miyu’s hand.

“…… Hot.”

With those words from Miyu, the torture ended. Having released everything I could, the erection finally subsided. The glans had become too sensitive, and I might not be able to wear pants today.

When the thorough torment by handjob ended, strangely, my consciousness returned to normal. It was a terrible state. Miyu’s body was covered in semen to the point that I couldn’t believe I had done it alone. If I collected the semen I ejaculated with this handjob, how much would it be?

“…… What, mi, Miyu! That, your… there…”

While I was looking at Miyu’s body, I discovered a major crisis. My semen had dripped down to Miyu’s crotch. Although it was only on the surface, the risk of pregnancy could not be zero. I quickly rolled up toilet paper and offered it to Miyu.

“Ah, this… It doesn’t matter.”

Miyu didn’t try to accept it. She just stared blankly at the semen dripping down her cleft. It couldn’t be that it didn’t matter. How much shock had I given her?

“I’ll wipe it. Just, I’ll only wipe it, so…”

I put my hand under Miyu’s skirt. I switched my head to a businesslike one, never getting excited, and carefully wiped off the semen that had landed on Miyu.

Since Miyu didn’t try to move herself, I also wiped off the semen that had stuck to her stomach. I took toilet paper several times, and every time, I was disgusted by the amount of semen I had ejaculated. When I finished wiping, Miyu finally stood up. In a posture with one leg raised, she stretched her leg, which had gone numb from trying to keep her balance, and took a deep breath. From between Miyu’s breasts, semen dripped slowly.

Miyu also noticed that it was her own chest that the semen had dripped from, reached out her hand to the hook of her bra, and unfastened it. Was her sense of shame blown away by the shock? Miyu shamelessly exposed her naked body in front of me.

Large, fair-skinned bulges. The elasticity and roundness formed the shape, and the nipples were slightly upward. Unlike Yamamoto-san’s perfect proportions, Miyu was unbalanced, small in stature but with big breasts. That was the most erotic thing.

Miyu took the toilet paper from me, carefully wiped between her breasts, and then threw it into the toilet. She picked up the T-shirt and skirt she had taken off on the floor. With her breasts emphasized by her bent-over posture, her rich breasts swayed, and unbelievably, my lower body was hardening again.

While picking up the clothes, Miyu looked at my penis, which was getting bigger in front of her eyes, and as she stood up, she directed a look of pity at me. I’m sure that’s the kind of eye that means looking at garbage. Miyu held the clothes in her arms and took the biggest sigh I had ever seen from her.

“I give up.”

She opened the toilet door and left. Seeing her back, I was filled with a sense of foreboding.

I would be discarded. Just like garbage. I understand that it’s unreasonable for a brother who has a girlfriend and has sworn not to use his sister as a sexual aid to still lust after his sister. No words of excuse came to mind. Still, I couldn’t bear the thought of being abandoned by Miyu.

I roughly wiped off the semen that was on my body and rushed into the changing room, flushing it down the toilet. Miyu was naked, cleaning the bath.

“Miyu!!”

When I called out to her, Miyu turned her face toward me without stopping the hand that was scrubbing with a stick sponge.

“What’s wrong?”

Miyu tilted her head. It was just a lovely face, as always. It felt like a normal atmosphere, but maybe it was just because I had gone beyond anger.

“Well, you know, I’m a hopeless brother, but I don’t want to bother Miyu, really, and, um, so, I want one more chance, I mean…”

My words didn’t come together. I didn’t know how to convince the one I had been abandoned by, or how to make her expect me again.

“One more chance… Do you want me to let you cum?”

Miyu replied, looking intently at my lower abdomen with a blank face.

“No, no…! That’s not it! I’d be happy if you did… but… no, I’m not happy at all… I’m happy, but…”

That sigh, which included resignation. I could only think that Miyu had given up on me. I just couldn’t say it honestly. While I was flustered, Miyu finished cleaning the bath and came out of the bathroom.

“You seem to be in a hurry. But I’m not angry?”

Miyu gave me the answer, sensing my feelings.

I also knew that she wasn’t angry now. The problem was whether it had returned to normal or whether she had become indifferent after being exasperated.

“Because, you know. When you left, you said, ‘I give up’…”

I was afraid that my heart would drift away from Miyu. It was the first time I had felt such an emotion while dealing with people. When I caused a problem in the fitting room before, I was also afraid of being abandoned, but at that time, she was clearly angry with me. I was scared of this Miyu, who was so calm.

“Saying ‘I give up’ doesn’t mean that…”

Miyu hesitated to answer.

“I can’t forgive you for dirtying the clothes, but I’ve already punished you for that, and your hard-to-deal-with hard-on is, well, hard to deal with.”

Miyu looked down at my hard-to-deal-with part. Maybe because her naked body was in my field of vision, my erection didn’t subside even in this situation. Knowing that I was so lacking in endurance, was Miyu really accepting me?

“Do you find it so hard to believe?”

Not knowing what question to ask to find out her true intentions, I remained silent, and Miyu came closer to me. There was a naked Miyu, a half-naked me, and a space equal to the length of my erect penis between us, and Miyu peered into my face.

“Do you want to take a bath together?”

When Miyu asked me, my head was completely overwhelmed. I was worried that Miyu had abandoned me, but instead, Miyu was showing me her heart more than ever before.

“Is that, like, game over if I say yes?”

“No. If you will trust my words, I’ll take a bath with you.”

Me, who was no longer a young man, taking a bath with my sister, who was two years younger. It was certainly something that couldn’t be done unless we were close.

“…… Then, I’ll take a bath with you.”

“Okay.”

While my heart was chilled inside, I answered “I’ll take a bath with you” with a desperate resolve, and it was accepted smoothly. Miyu stopped the bathwater, prepared two bath towels, and said,

“I’ll take a shower first. You can come in at any time.”

“Okay. I will.”

While Miyu was washing her hair, I wet my body with the shower. When I started shampooing, Miyu rinsed her head and began to wash her body. Miyu’s breasts, which were not hidden by the bubbles, swayed every time she slid the body soap. The pain in my groin didn’t go away, and I was embarrassed to be seen by Miyu while I was washing my own body after she had finished washing her whole body.

Then I got into the bathtub, and Miyu sat in the space in front of me. Miyu’s hair was tied up with a hair clip, and when I saw her back and neck close up, the fineness of her skin stood out. I never imagined that I would take a bath with Miyu. I don’t have a clear memory, but I don’t think we ever bathed together like this when we were children.

“Do you trust me even a little?”

Miyu asked me, showing only her profile. After being treated like this, it would be rude not to trust her.

“Yeah. I’m sorry.”

Anyone would have been anxious with such an attitude. But those who are being doubted shouldn’t feel good either. Then let’s trust her. If I’m abandoned, there’s no way to get back on track anyway.

It was the first time I had taken a bath with my younger sister since I became aware of the difference between the sexes. The bathwater, which had increased in volume for two people, rose up to my shoulders. I often just took a shower, but in the summer, my body gets cold from sweat and air conditioning.

It’s nice to take a bath like this sometimes. The pain in my glans when I entered the bathwater was extraordinary, but after a while, it began to heal.

“Anyway, you really came a lot.”

“You, so, that’s…!”

Maybe it was Miyu’s way of trying to make the atmosphere more relaxed. Still, I think it’s a topic that’s too awkward to talk about.

“Even though it was by force, I did it by hand.”

“Yeah. I was forced to cum.”

“Was it good?”

“Of course, with that much coming out…”

It was a pleasure hell that made my head spin. I didn’t want to be tortured like that again, but if it was allowed, I wanted to be stroked by hand again.

“I won’t do it again.”

“Eh…”

This preemptive move, as if reading my mind. It’s a pity, but I also have a girlfriend. That was, well, an accident. Rather, it was nothing but an accident.

So, taking a bath like this is also an accident. And the opponent is my blood-related sister, my family, so there is no problem at all. Therefore, even though I want to grab and knead Miyu’s breasts, which I can see from behind, it’s also within the scope of an accident.

“Mi, Miyu. That… it’s sticking to your back, but is it okay…?”

My erect penis was sticking tightly to Miyu’s back. It was also because there wasn’t much room in the bathtub, but Miyu was leaning back without caring about it.

“Just for today. I’ll let you off the hook.”

Miyu was supposed to dislike skinship. Especially, she shouldn’t have touched an erect male organ. What kind of change of heart was this?

“Then, I want to ask you something hypothetical.”

“Okay.”

“I want to grope your boobs”

“Absolutely not.”

Yeah, I knew that. I knew that. Miyu especially hates having her breasts touched.

“Onii-chan.”

Miyu leaned her weight on her back and raised her chin a little.

“Your pulse is amazing.”

When I was pointed out, and realized that it was being felt from my erect penis, a sudden sense of shame rose up, and my whole body became hot.

“So, so sorry! Well, because, this is…”

I was excited by the desire to touch Miyu’s breasts. My psychological state was transparent with my body so close to hers.

“You’ve been hard since earlier in the toilet.”

“Yeah… That’s right…”

There was no excuse. I should have run out of semen to ejaculate, but why was I getting so hard?

“Are you always that energetic?”

“No, this is…”

I should tell the truth.

“Only when I’m with Miyu.”

I was aware that I had a strong sex drive. But the only time I stayed hard after ejaculating was when Miyu was stimulating me.

“Hey, can I ask you a more intimate question?”

“…… What?”

Miyu blinked her big eyes and averted her gaze, then thought for a moment. It was her usual habit, but I didn’t know what it meant. There was a gap of a few seconds, and as I wondered what she was going to ask me, my heartbeat grew stronger, like a big drum, “Dokun, dokun.”

“Onii-chan, do you want to get me pregnant?”

To that overly intrusive question, of course,

“N-No! I’ve never thought of such a thing…”

I immediately denied it. I didn’t have the ability to take such responsibility yet, and I had never wished for it. But with that much ejaculation. I didn’t know what my body thought. And…

If Miyu said it was okay to have sex with her. I would probably give in to my desires and take advantage of my sister.

“Hmm. Well, it doesn’t matter either way.”

Miyu turned her face forward and hugged her knees. If it doesn’t matter either way, why did you ask? I don’t understand, but somehow, these feelings. Miyu’s figure, which I was looking at from behind, was very, very beautiful. I’ve thought girls were cute many times, but I’ve never felt such an emotion from the bottom of my heart.

Cute. Miyu is the cutest in the world. Being with Miyu calms me down. When our skin touches, my heart beats faster. I used to think it was just excitement for an unfamiliar female body, but I, really, from the beginning, I…

No, wait, no. Don’t think about it. We are siblings. We will never become anything more than that.

“Your heartbeat is very fast.”

“Ah, ah.”

“Is my naked body that exciting?”

Please stop. I can’t deny it.

“I think Onii-chan is really going to die soon, so I’ll get out first.”

Miyu straddled the bathtub, took a light shower to rinse her body, and went out to the changing room.

Ah, that’s right, I may have been misunderstanding things.

I don’t have any romantic feelings for my sister.

“I’ll make dinner while you’re changing. Come and eat.”

Miyu poked her head out, wrapped in a towel, and said that last thing before going upstairs.

She’s so cute. I have to correct this heart, which thinks so even when I try to be indifferent, now. If I let my guard down with my sister any more than this, I might go too far and not be able to recover.
