My Little Sister Is the Best F*p Material - Volume 2 Chapter 03: Congratulations on Losing Your Virginity, Onii-chan

Volume 2 Chapter 03: Congratulations on Losing Your Virginity, Onii-chan

My penis, which had regained its hardness due to my sister’s command, was pulsating with a “dokudoku” sound in the quiet living room during the day. The two of them, still young and innocent, were looking at my erect penis with their pure eyes… except for Miyu.

“It’s gotten big again…”

Sachiko was observing my erection with curiosity. Even for me, a man, the part of my body that gets bigger when I’m excited is a mystery. For Sachiko, who doesn’t even understand health and physical education properly, it must be even more so.

“Onii-chan is trying hard to have sex with Sachiko. You should praise him for that.”

“I see. It looks like it’s a lot of work.”

Sachiko came closer to my knees with a four-legged walk. The glans, which had turned red due to congestion, was once again more sensitive, but it should have lost its sexual sensation due to ejaculation and was now just a sensitive part.

“Good boy, good boy.”

Sachiko’s hand stroked my penis. With a pure heart. As if she was cherishing it.

“Aaa… guu…”

My waist twitched with a “bikk.” Perhaps because she felt her kindness, even though my glans, which had just ejaculated, was being rubbed directly by her palm, I had somehow returned to the realm of pleasure.

“Is it better to stroke it rather than grip it?”

Sachiko was caressing not only the tip but also the shaft and the testicles with a feather touch. Because of her lack of knowledge, she had little resistance, and Sachiko’s sexual technique was absorbing the information given by Miyu like a sponge.

Sachiko smoothly performed caressing my penis, licking my testicles, kissing, and handjobs. Since the reference material was an erotic video for men, she was perfectly reproducing the foreplay that men enjoy. And her expression was slightly flushed, and she was looking at my penis with a droopy face, as if she was enjoying it.

“Fumu… muchu… does it feel good..?”

“Aa… it’s so… I want to be like this forever…”

“Nfu fu. Ngu… guchu… nku…”

Once she put it in her mouth, she swallowed it all the way to the back. She completely included my penis from the glans to the root in her saliva-filled mouth. This technique couldn’t be from a girl who doesn’t even know what sex is. Her skill had improved remarkably.

“Aaah… Sachiko… if you do it like that, I’ll ejaculate in your mouth again!”

“Nnn…”

Even though the purpose was to have intercourse, when I wanted to ejaculate in her mouth again, Sachiko stopped moving as if she was scared. Apparently, the semen that was ejaculated into her mouth earlier was so bitter that it became a trauma. If this continues, she might start to dislike fellatio. Perhaps sensing my worry, Miyu approached Sachiko from behind and lowered her panties, putting her hand on her cleft.

“Sachiko should also start preparing soon.”

“Feh… nkyu…!?”

Sachiko’s body tensed as she moved with Miyu’s hand.

“Aah… hau… aaan… aah…”

“You shouldn’t take your mouth off. Continue your service.”

“Fuh… ngu…! Nn… hafu… nchu…”

Sachiko’s fellatio became more intense as she was manipulated by Miyu’s hand on her private parts. She was trying to push the pleasure given by Miyu out of her thoughts as she devotedly sucked on my penis.

The face she made while sucking on my penis was not a fake female face. Her face, which had completely melted due to Miyu’s fingers, showed no strength in her facial muscles, and it was the face of a lewd girl.

“Sachiko… that… if you do it so intensely… I won’t be able to hold on…”

“Haa… mug… nnn… n… nN~ aaah!”

Sachiko’s secret place was making more water sounds, and love juice was overflowing throughout the room. Or maybe Miyu was doing it on purpose to excite us. Sachiko’s moans were so wild that they didn’t even sound rational, and it seemed like she couldn’t even hear my voice.

“Miyu-cha… aah… I’m… I’m gonna cum… guchu buchu… nku… nnn…!”

Sachiko was sucking on my penis and moaning in pleasure from the sensation Miyu was giving her. Miyu was carefully loosening Sachiko’s vagina to prepare her for sex, even though she was a virgin.

Sachiko seemed to have experience with masturbation, so I could understand that she had a certain level of sensitivity. What I found strange was that Miyu’s fingerwork was too good. Unless she was very used to playing with female bodies, she shouldn’t be able to bring someone to such a state of pleasure.

Does Miyu masturbate too? I wonder if this girl, who always looks grumpy, would moan and writhe like Sachiko, and release her sexual desire like a scatterbrain. If there is such a Miyu, I want to see her. I wonder what position she takes when she masturbates. What kind of voice does she make, and how does she lose control?

“Haaannn… Miyu… hya… stop it… mou…!!”

“Are you going to cum? It’s okay. Girls can cum as many times as they want.”

“Aaah! Miyu-chan’s finger… it feels so good! Nn… aaah… aaahhhh!”

Sachiko moaned as she shook her body. She was trying to hold back her uncontrollable body by putting all her strength into her hand that was holding my waist.

“Let’s make it a little more guchu guchu since it’s your first time.”

“Mou no more noo… aah, aah, after I cum… rame… n, nnn, nNaa! Ahima, okahiku naryu noo…”

“I haven’t touched the good spot deep inside yet. Here, look.”

“I’m… aah… aaappaa! T-T-There, a! Miyu-cha, nyoooo… aa… a!”

It was almost a scream. She was expressing the limits of pleasure from the depths of her throat, ignoring my penis. Miyu’s fingers, hidden by her skirt, seemed to have perfectly captured Sachiko’s sweet spot.

“Nice going.”

“Ah… aah… I’m so tired… I’m fine with being Miyu-shama’s slave…”

“Don’t be so limp. The main event is next.”

Sachiko’s consciousness was hazy. Her face, which was completely relaxed, was half white-eyed, and if this were a two-dimensional expression, it would definitely be drawn as an “ahen” face.

“Are you ready, Onii-chan?”

Miyu didn’t seem to care about Sachiko, who was barely breathing. She was just doing what she had to do to fulfill her mission of letting me have sex. I was ready too. In fact, I was too ready, and I was worried that I would ejaculate the moment I inserted it. But at this point, there was no turning back.

“I-I’m ready.”

If I pulled out now, it would be rude. I want Sachiko. I want to lose my virginity to her.

“I’ll bring the condom, so tell me where it is.”

“Condom…? Ah…”

When Miyu said that, my head suddenly cooled down.

“I don’t have it.”

Although I had been trying hard with Miyu under the pretext of having sex until today, I didn’t think it would happen so soon.

“You don’t have it? Don’t you use it when you masturbate alone?”

“I don’t use it.”

I don’t remember ever using a condom in front of Miyu when I was masturbating. Rather, how did she think I, a virgin, would have one?

“Don’t you put on a condom when you use an onahole?”

“I’m from the no-condom school. I didn’t have it on before either.”

“I asked if you didn’t wear it.”

“At that time, there were circumstances…”

When I had fake sex with Miyu, I didn’t know I was being used with an onahole, and I thought we were having raw sex, so I suggested it. Of course, if that were the case, I would have gone to buy a condom, and it was also a way to calm the situation down.

“Moo… what should I do…”

“Should I go buy it now? I heard they sell it at convenience stores.”

“In that state?”

Miyu started hitting my penis with the pointer. I wish she would stop because it’s making me a masochist.

“I’m sorry…”

“Haa… I guess there’s no choice.”

Miyu sighed heavily and went upstairs.

By that time, Sachiko had calmed down, and our eyes finally met.

“Err… from now on, I’ll insert it. Is that okay?”

“Yes, it is? And you,  Onii-san, are you okay with it?”

“For me, it’s a dream come true.”

Having a cute younger girl lose her virginity to me. There’s no better deal for a man.

“Then, let’s do it without thinking too much. …Should I lick you until Miyu comes?”

“Oh, okay.”

Unexpectedly, Sachiko was proactive, and I let her lick my penis again.

“If I do it too much, you’ll ejaculate.”

“Aah… kuh… that’s right.”

Sachiko was also honest and understood my reaction. Basically, she just licked it, but when she had some spare time, she would bite the tip. A girl like her, who takes care of a guy like me, is an angel.

“Fumu… juru… muchu… fa… amu…”

“Sachiko… it feels so good…”

“Nfu… I’m gwad…”

Sachiko talked to me while licking, with a tongue-tied voice. Just then, Miyu came down the stairs.

“Here. Use this.”

What Miyu handed to me was a condom. …Why does Miyu have such a thing? Confused, I tried to take it, but Sachiko took it from my hand.

“Ah. I know this.”

Sachiko held it up to the ceiling and checked the front and back. Wait, wait. You two are virgins, right? As for Miyu, I can understand, but Sachiko should have no experience with sex. Then why does she know about condoms that I’ve never even touched?

“This is the same one I saw in Haruka-chan’s room… fuguh!?”

“Sachiko, don’t say anything unnecessary.”

Miyu covered Sachiko’s mouth. Haruka, I remember, is a lesbian. Why does a lesbian need a condom? I don’t understand anything anymore.

“Hurry up, Onii-chan.”

Urged by Miyu, I tore open the condom package. The square vinyl package was easily torn open with my fingers. Inside was a rubber soaked in lotion. The base was curled up, and the spotless bulge in the center was probably the semen reservoir. I just have to put it on my thing, which is hard.

“Onii-chan, that’s the wrong way. You have to lower the curled part in the right direction.”

“So, sorry.”

I wonder if there’s a brother in the world who gets a condom lesson from his sister. Anyway, how does she know how to put on a condom when she doesn’t use it? I was embarrassed and put the condom on awkwardly while Sachiko watched the moment of attachment intently.

“I, I put it on, but…”

“Sachiko, cross your legs over your Onii-chan’s.”

“Yes, I understand.”

Sachiko also couldn’t resist without any resistance. Her face was tense, either because of shyness or fear of losing her virginity, as she positioned her wet meat hole on my thing.

“I, is it okay?”

“Uu… i… it’s okay…”

We were both stammering, and Sachiko slowly lowered her waist. I held her waist with both hands and first put the tip on her crotch. I tried to push it in a little, but I couldn’t feel any holes there.

Wait a minute. Where is it? I can’t find the hole. I want to insert it more smoothly… Is there really a hole?

“Mo, more, back…”

“Aa, sorry!”

I made her say it. Showing such a panicked face because I can’t find the hole is the worst thing a boyfriend can do, but my head was confused, and I didn’t know how to get back on track.

I have to do something. If I take too long, Sachiko’s cleft will dry up. But no matter how much I moved the shaft back, there was no hole that could be inserted. All I felt was the slippery flesh hitting the tip of my penis. It felt good, but I couldn’t enjoy the pleasure because I felt sorry for Sachiko.

“Um, more, back…”

“Eh? Is this…?”

The glans sank into a dent-like place. It seemed like it could be inserted if I pushed it in. But if it’s that far back…

“I-Is this, the anus and not…”

“N-No, it’s the right place.”

“Seriously? Then, I’ll insert it.”

“U… nnn… aah…”

After the corona was caught, it was inserted quickly. My penis twitched with a “bikk” as it was enveloped by a much hotter body temperature than the skin surface.

“God… damn… Sachiko, it’s so hot…”

“Nn, aah…! It’s in…”

I realized that I had lost my virginity. There was no time to reflect on it. Finally, the root entered Sachiko’s vagina, and the whole process was witnessed by Miyu.

“I, is it painful…?”

“Eh, um, it’s not that it’s not painful, but it’s not that bad…”

“I’m glad to hear that.”

Miyu loosened it a lot. Normally, it wouldn’t be so easy to insert it for the first time with a girl.

Sachiko covered my body, and her chest, which was bigger due to the height difference, came right in front of my eyes. If it were a lover, I could do whatever I wanted with her breasts, but I refrained from taking off her top at this timing.

The connection part was hidden by her skirt. I inserted it without even knowing what a girl’s body was like. I wanted to see it, but I wondered if Sachiko would be embarrassed. Because it was the first time, I wanted to confirm the connection with my own eyes.

“Nnn…”

When I slowly moved my waist, Sachiko slightly lifted her waist. Then, she lowered her waist again and welcomed my penis deeper into her vagina.

“Sachiko, is it good…?”

I asked, and Sachiko didn’t look at me. She looked down, and her side tail apologized apologetically.

“I, it feels so strange…”

That was definitely not a positive opinion. Is this what it’s like for the first time? I guess it’s okay as long as she’s not in pain.

“Are you fine with me moving?”

“Y-Yes. Um, if you go slowly… just a little… deep inside, it kinda goes kyun…”

“I see.”

I understood that there was some pleasure in the difficult expression unique to girls. Until now, it was thanks to Miyu. From now on, I’ll make her feel good with my penis.

“Nuuu… haa… uhh… O-niisan’s… looking at what you put inside me… it’s big…”

It seemed that the size of my penis was satisfactory for the narrowness of a virgin’s hole. As I moved my waist slowly to carefully feel the texture of Sachiko’s vagina, her reaction gradually improved. Maybe a more intense in-and-out motion is not as pleasurable as a slow tempo.

“Agh… uuuu…! It… it’s hard… aah…”

“Sachiko… it feels good…”

Still, the movement of my waist gradually became faster. I wanted more. I wanted to immerse myself in this texture. I wanted to rub my sex organ in this hole, which should be called a “nikutsu,” forever. I couldn’t do slow sex.

“Sachiko… Sachiko…”

“An… onii-san… t-too hard…!”

“Ugh…! I can’t hold on anymore…”

“I, it’s okay… cum… cum inside me…”

Sachiko also started stroking her waist in time with my movements. She was telling me with her body that she wanted me to cum inside her vagina. Is it okay? Cum inside this girl’s vagina… In front of Miyu—my real sister. Using the body of her friend, I was about to ejaculate.

“Aah… this is bad… mou… aah… Sachiko…”

“Cum, Onii-san, cum inside me…”

“Haa… aah… I’m gonna cum… Sachiko…”

Pann, pann, pann, I thrust my waist hard, as if to shake off my doubts. Without caring about my sister watching me or the fact that I was ejaculating into the vagina of a virgin, I ejaculated all my desires into her vagina.

“Onii-san…”

“Sachiko…”

My penis repeatedly expanded and contracted with each ejaculation, pushing open Sachiko’s vaginal canal and sending out semen. Even with a condom on, the fear of ejaculating inside a girl’s vagina didn’t go away, and I finished ejaculating in a shivering sensation of pleasure.

“Haa… haa… I… I came…”

“Hihi,  I’m glad I did it properly.”

We were both out of breath, and in the end, Sachiko hugged me.

Ah, this is it. It feels like we’re lovers. I’m enveloped in an immense happiness. I’ve finally graduated from being a virgin. With such a cute girl.

For a while, Sachiko and I hugged each other. I realized that Miyu was no longer there, and it seemed that she had left the room without me noticing.

After our breathing calmed down, Sachiko sat up. With her knees shaking, she raised her waist, and my hard penis slipped out with a slimy sound. The tip of the condom was filled with semen.

“Hehe. It’s kind of embarrassing.”

Sachiko quickly put on her pants as if to hide her embarrassment.

“Yeah.”

There was a strange awkwardness after sex. It was not unpleasant, but it was frustrating and frustrating. Sachiko straightened her clothes and pointed to herself with her index finger.

“I’m your girlfriend… right?”

My heart fluttered at Sachi-ko’s words.

Yes. I’m Sachiko’s boyfriend.

“Of course. Let’s go on a date from now on.”

“Yes!”

And so, I successfully got a girlfriend. I chatted with Sachiko for a long time, but there was no sign of Miyu coming down. Before the sun set, we disbanded.

I saw Sachiko off at the entrance, returned to the living room, and picked up my smartphone, regretting that I should have exchanged contact information.

I thought I could ask Miyu, and as I turned on my smartphone, a message from Miyu arrived.

— Congratulations on graduating from being a virgin, Onii-chan.

“Miyu. Thank you.”

I lay down on the sofa, which still had Sachiko’s warmth, with my smartphone in my chest, displaying Miyu’s congratulatory message on the screen.
