My Reality Became a Zombie Game World, but Only I Can Use the Game System - Chapter 23: Reverse Bunny, Sex with Yume-nee

Chapter 23: Reverse Bunny, Sex with Yume-nee

“Um, this outfit, as your Onee-chan, I think it’s a bit different…”

“Didn’t you say, Yume-nee, that you’d wear any costume skin?”

“…I did say that.”

Yume looks down at her outfit, feeling so embarrassed that her face feels like it’s on fire.

The costume, inspired by a rabbit, is the opposite of a typical bunny girl outfit, with the parts that should be covered exposed, and vice versa. Her arms and legs are covered in black fabric, while her ample chest, belly, and groin are almost completely exposed. The nipples are covered by heart-shaped nipple pasties, and her groin is covered by a C-string, but the unnaturally thin fabric makes the shapes of her nipples and labia stand out clearly.

Ritsu explains that this is called a reverse bunny outfit.

Yume is shocked that such an obscene outfit has a name.

The costume skin, purchased from the store, allows her to change into the outfit instantly when selected from the menu. Even though she consented to it, the lack of preparation time makes her feel confused and embarrassed. Yume is seated on Ritsu’s bed, her head filled with confusion and shame.

“Um, Ritsu-kun, are we really going to do this in this outfit?”

“It’s awesome, Yume-nee. Your incredibly lewd body is on full display.”

“Uuu…”

Yume wishes Ritsu wouldn’t call her lewd so often.

She is aware that her body, with its ample chest and hips, is attractive to men.

It’s an everyday occurrence for her to be the focus of men’s lustful gazes. Each time she felt a sense of revulsion.

But Ritsu’s gaze is different.

Every time she moves, her heavy breasts sway and bounce. Ritsu, with an excited expression, lets his gaze wander over her white breasts.

The same lustful gaze of a male, yet instead of feeling revulsion, her body heats up with excitement. From the day Ritsu saved her, he has been special to Yume.

Wearing this lewd outfit, and being seen by Ritsu, her white skin flushes with heat, and the exposed parts turn crimson with excitement. The sweet scent of her sweat, inviting men, seeps from her reddened skin.

Ritsu takes out a Skill Drug from his storage inventory. He purchased it just three days after Yume said she’d wear any costume skin. Ritsu’s motivation is incredible, and despite the high price of the item, he quickly gathered the necessary Information Value Orbs.

Ritsu explains the effect of the Skill Drug again.

“When you drink the Skill Drug, you gain a skill. If you have sex with a girl by ejaculating inside her within four hours of taking the drug, the girl will also gain the same skill.”

Yume nods, feeling her cheeks heat up.

She can’t waste such a valuable item. Once Ritsu takes the Skill Drug, Yume will have no choice but to submit to his ejaculation inside her. Agreeing to this, knowing what it entails, feels like a very lewd act.

Ritsu swallows the Skill Drug.

His crotch becomes even more tented, pushing up his pants. The Skill Drug has an aphrodisiac effect. Yume won’t be released until Ritsu ejaculates.

“Yume-nee, I’m going to touch you.”

“U, um…”

The excited Ritsu embraces Yume from behind and roughly gropes her marshmallow-like breasts.

Yume’s breasts, almost fully exposed in her reverse bunny outfit, are distorted by the rough, hot palms of a man.

“Nn… aah♡ Hiuu… n… ya… an… ahn♡”

Even though Ritsu is just enjoying himself by roughly groping her breasts, the sheer pleasure makes her moan.

Ritsu, obsessed with Yume’s body softness, repeatedly squeezes her oversized breasts, which don’t fit entirely in his palms. She thinks to herself that he’s always been fascinated with her breasts.

“Fuh…♡ A, n, hiaan♡”

Ritsu forcefully removes Yume’s nipple pasties. The breasts, stretched like rockets when pulled, then return to their original shape with a jiggle. The crude fingers of the man rub and tease her bare nipples. While Ritsu teases her nipples with his right hand, he removes the C-string that was covering her vulva with his left.

“Aah♡ There, ya, nnn… aah♡”

Her most private parts, which should not be seen as a girl, are now completely exposed. Even that would be embarrassing, but Ritsu freely teases her fingers as if this female body is his. His fingers move freely inside her vagina, which is now a mess of love juices.

Unlike the initial rough movements, Ritsu’s fingers now move to give Yume pleasure. She moans naturally as she receives the pleasure.

“A… n… ya… fuu♡ Fuu♡ Nnnnn♡”

Ritsu’s rough breath blows against Yume’s nape. She can tell that the boy is completely obsessed with her body.

Come to think of it, this might be a chance.

The first sex with Ritsu in the infirmary was enjoyable, but it was far from what she imagined. To put it simply, it wasn’t like a real Onee-chan to be like that.

Yume fantasizes about her ideal Onee-chan sex.

Ritsu, obsessed with Yume’s body, becomes immersed in it, but Yume maintains a composed expression as she accepts his carnal desires. As Yume takes the lead, Ritsu can’t help but ejaculate immediately, and apologizes. Yume comforts him gently, saying, “Ritsu-kun, are you satisfied? Onee-chan also felt good earlier.”

Yes, Yume thinks. It’s really good. Let’s do this.

Ritsu’s fingers roam further, and the pleasure of being caressed makes Yume’s lower abdomen throb, and she feels like she’s about to climax.

This way of letting Ritsu take the lead is not good. This will lead to a repeat of the previous situation.

“Nn…♡ Hey, Ritsu-kun… I’ll move on top of you… n♡”

As she feels the sensation of the large penis against her buttocks, Yume proposes.

Her plan was to ride Ritsu in the cowgirl position and teach him the pleasure of sex with his Onee-chan.

“R-Really?!”

Yume’s proposal makes Ritsu’s penis jump.

He’s excited at the thought of making Yume, in her reverse bunny outfit, serve him in the cowgirl position.

Ritsu eagerly takes off his clothes and lies on his back on the bed.

Yume straddles Ritsu, positions herself so that she feels the penis against her soft buttocks, and then, feeling a bit anxious, asks,

“Um, is this… heavy?”

“It’s totally light. I’m happy to feel the weight of Yume-nee.”

“U, um. I’m happy too.”

Yume nods deeply at Ritsu’s words.

Before she lost her virginity, she thought that sex was something that men enjoyed. It’s inevitable that she’ll let her beloved Ritsu have his way, but she thought that she wouldn’t be happy about it.

But she was wrong. As Ritsu said, it’s very pleasant to feel the weight, the touch of the skin, and the body temperature of her partner. Joy and happiness overflow from her heart and she can’t stop it. Remembering her first time, Yume’s vagina is already soaked. She wants to be connected again and experience that feeling of bliss once more.

“Um, well, should I… insert it…?”

“Yeah…”

As Yume raises her waist to welcome Ritsu’s penis, she is perplexed.

Even though she raised her waist to a comfortable height, the tip of the penis is already hitting her cleft. Ritsu is lying on his back and there is no sign that he is moving.

Huh? So this means the penis has grown to this height?

She didn’t notice it because she was so nervous during her first time, but was it this big? Or is it because of the aphrodisiac effect of the Skill Drug?

Imagining guiding this large member inside her, more love juices flow from her vaginal opening. Yume’s female sex organ desires to be invaded by the male, who will widen her small hole.

Will she still be able to be an older sister figure after being penetrated by this?

Yume becomes anxious, but still makes up her mind. Since it’s a cowgirl position, she has the lead. She just needs to move at a pace she can endure and squeeze out Ritsu’s semen.

She moves her fingers to guide the penis, and as she applies it to her vaginal opening, she lowers her waist.

“Nhu… it’s big…♡”

The sufficiently wet vagina, more easily than the first time, swallows Ritsu’s penis.

As she endures the pleasure that runs up her spine from her groin, she somehow manages to swallow the penis with her lower mouth.

The sight of Ritsu looking pleased makes Yume incredibly happy.

The satisfaction of being connected to a man she loves and giving him pleasure. She wants to make Ritsu feel even better. Her waist is trembling on the verge of climax, but she manages to slowly raise her waist again.

“Haa… haa… nuh…♡”

She repeats the action of slowly raising and lowering her waist.

It’s fun to look down on Ritsu’s expression as he endures the pleasure.

Every time she moves her waist, the plump fruit swings lewdly, and Ritsu reaches out his hand.

While Ritsu is obsessed with the softness of her breasts, Yume is satisfied as she slowly moves her waist.

Yume, who is moving her hips in a hip-hip motion, is convinced that Ritsu is satisfied with her movements. The girl, who is satisfied just by being touched and connected, didn’t know that men prefer more intense movements. So, when Ritsu grabbed her waist strongly, the first emotion that came to mind was confusion.

“Sorry, Yume-nee. I’ll move now.”

“……….. hiaaaaaaahhhhhhhhhhhhhhh♡”

BACHUN!

Ritsu thrusts Yume violently.

Yume is unconsciously avoiding the deepest part of her vagina, but she can’t help but moan as she is penetrated deeply.

Tears well up in the corners of Yume’s eyes, her whole body shakes, and she squirts. With just one thrust of the male’s genuine intent, Yume’s body easily reaches its climax.

Yet, Ritsu is not at all satisfied. While holding Yume’s waist firmly, he starts moving again.

The answer that her pleasure-dominated brain could barely deduce was to ask for forgiveness quickly. She had to stop this before she broke.

“A, a, a♡ Wait, Ritsu-kun, wait♡ I can’t take it, forgive me♡”

“Sorry, sorry, Yume-nee.”

Even as he apologizes, Ritsu doesn’t stop thrusting from above.

Yume twists her waist to escape the intense pleasure, but when she is hit hard in the deepest part of her vagina, she easily reaches her climax and her strength fades. Escape, fail, climax, escape, fail, climax. Repeating this process, Yume becomes unable to resist and becomes a doll that is only raped.

Understanding that she can’t escape the pleasure, Yume’s body unconsciously opens her legs and moves her waist to make it easier for the male to thrust. Sweat and love juices fly, and the sweet scent of Yume, which excites Ritsu, fills the room. Every time she is thrust, her ample white breasts swing, pleasing the male’s visual senses.

“Hia♡ Ya, aah, aahhh♡ Ya, a, hin…♡”

Yume raises her back and looks up, moaning to escape the pleasure that resonates throughout her body. She can’t seem to endure the pleasure given by the penis unless she raises her voice.

Even in this situation, Yume’s vagina clings to the penis, stroking it as if serving it. Ritsu’s penis grows larger with the vagina’s movements, which beg for ejaculation inside.

“Hin…♡ A, yaa, n♡ Again, move faster… hin♡ Hiin♡”

The movements become faster, and Yume’s voice volume rises.

She realizes that ejaculation is near. The moment she understands, Yume’s body tightens her vagina. Her vagina, without any gaps, tightens around the penis, helping it achieve the best ejaculation. That movement seems to have been the coup de grace.

“Yume-nee, I’m going to ejaculate!”

“Ya, I’m gonna cum♡ I’m cumming♡ ~~~~~~~~~~~~~♡♡♡”

DOBYU! BYULLULLULLULLULLULLULLULLULLULLULLULLU!

Ritsu’s penis explodes inside Yume’s vagina. The tip of the meat spear is pushed against her uterus, and she can feel the flow of a large amount of white fluid.

Ritsu’s hand firmly presses against Yume’s waist, but even without that, Yume wouldn’t have escaped. Her brain was so dominated by the feeling of bliss that she couldn’t. The happiness of a female infatuated with a strong male being impregnated. She can’t think of anything, just opens her legs and continues to accept the long ejaculation.

“Hia♡ A, a, a♡ Ah, aah♡ Nnuh♡”

Yume regrets that she couldn’t hold back the white fluid that overflowed from her vulva as she immerses herself in the afterglow of her climax.

She is immersed in happiness, feeling like she wants to be connected forever… and then she suddenly realizes. It’s a little different from the plan, but the older sister sex is not over yet. She should be able to regain her pride as an older sister from here.

After somehow arranging her melted face into a smile, she speaks to Ritsu.

“Ritsu-kun, are you satisfied?”

“Sorry, I’m not at all.”

“……….. what?”

Her smile collapses in confusion.

For the first time, she realizes that Ritsu’s penis is still hard and erect inside her vagina.

During the sex in the infirmary, Ritsu was not satisfied with just one ejaculation and went on to other girls.

Yume’s breath is rough, and her waist is trembling from the multiple climaxes. She doesn’t have the strength to move anymore.

“Um, I’m a little tired…”

“Yume-nee! Yume-nee!”

“Hia♡ Ya♡ A, n, no, yaa♡”

Yume is forcefully pushed down, and this time she is penetrated in the missionary position.

She doesn’t have the strength to push him away. She tries to plead for him to stop, but when she is thrust hard in the deepest part of her vagina, all she can do is moan.

The usual Ritsu would probably be considerate of Yume, but the aphrodisiac effect of the Skill Drug has exploded the boy’s sexual desire.

As Ritsu’s rampage continues uncontrollably, Yume is raped by him over and over again.

She is ejaculated inside her vagina multiple times in the missionary position, and then multiple times in the doggy style position.

BYULLULLULLULLULLU! DOBYULLU!

“Aah, a, a, hia♡ Ahhh♡”

Finally, in the backbend position, Yume is brought in front of the mirror in the room.

“Yume-nee, look. It’s very sexy.”

“Ya♡ A, ya, ya, don’t look, yaa♡”

Even though her consciousness is hazy, Yume witnesses her lewd appearance in the mirror.

A fan-shaped figure with her chest and groin exposed, even though she is wearing clothes.

Semen drips from her virgin cleft, and at first glance, it’s obvious that she’s been ejaculated inside her vagina multiple times.

Her whole body limp, yet still accepting the penis while being held by a man, she looks like a sex toy for processing.

Every time she is thrust, her ample white breasts swing, and Ritsu’s gaze is fixed on them, making her strongly realize that she has a body that attracts men.

Her expression is completely melted in pleasure, and her moans escape with even the slightest stimulation, making her look like a whore.

What made Yume feel the most embarrassed was the fact that this was sex.

The first time was an inevitable act to gain immunity.

The second time was an inevitable act to gain a skill.

But there is no such excuse for this act. Ritsu is just thrusting his penis into Yume to satisfy his hunger, and Yume is accepting it. In her lewd reverse bunny outfit, Yume is inviting Ritsu to ejaculate inside her vagina.

“I’m gonna cum again. Sorry, Yume-nee, I’m gonna cum again in your lewd body.”

“Hia♡ Ahn♡ Hh♡ Aaahn♡”

I have a lewd body…♡

Through being raped by Ritsu over and over again, self-awareness begins to grow in Yume’s heart.

It was arrogant to act like an older sister during sex…

Before being an older sister, I’m a girl who tempts Ritsu-kun with my lewd body…♡

Yume’s vagina tightens, and she tries her best to serve Ritsu so that he can ejaculate pleasurably.

“Yume-nee, I’m gonna cum again.”

“Fuu♡ Fuu♡ N♡ Ahn♡ A, aah♡ I’m cumming♡ I’m cumming again♡”

Yume’s entire body is dominated by pleasure, making her unable to hear Ritsu’s voice.

Even though her body’s strength is gone, her vagina alone continues to strongly squeeze the penis, writhing complexly.

Finally, with a strong thrust, Ritsu pushed his penis deep into the girl’s vagina and began to forcefully ejaculate inside her, making her unable to escape.

“Ahhhhhhhhhhhh♡♡♡”

Yume, with a blissful expression on her face as she is ejaculated inside her vagina by the man she loves, loses consciousness.

“Fuu, that was incredibly pleasurable.”

I caress the head of Yume-nee, who is sleeping next to me on the bed, breathing softly.

“…”

It’s true that I feel a sense of happiness from the sex with Yume-nee. I also feel a sense of love for this person.

If I use my powers as a player, I probably won’t have any trouble living.

If we find a place to live together as a couple, that will be the happy ending of my story.

That’s what I tell myself. Otherwise, I might end up looking for a replacement for “DL4.”

I don’t feel like I can sleep yet.

On a whim, I pick up my smartphone.

When I search for information about zombies, a news video about Tokyo Sky Tower appears.

Tokyo Sky Tower is a 634-meter-tall radio tower, located just 5 kilometers away from here.

Since Yume-nee is sleeping, I turn on the subtitles and watch the news silently.

It seems like the footage is being taken from a helicopter. The reporter on the helicopter seems to be shouting.

“Look! Can you see it? That’s Tokyo Sky Tower! The radio tower constructed by the Tri-color Conglomerate is covered in something mysterious, something like a strange piece of meat! You can see a giant eye-like object embedded in the meat wall! This is not a movie! It’s actually happening right now, in front of our eyes! Oh, something has been fired from the tower! A meat bullet is heading this way–!”

The video cuts off there.

I rewind the video and watch it from the beginning.

One of Tokyo’s landmarks is covered in what looks like rotting flesh. A single black pupil is embedded in the meat wall of the tower, moving around like it’s alive.

Looking at this grotesque structure, the first thing that comes to my mind is:

–It’s like a boss stage from “DL4,” and it looks like it would be fun.

I can sense intuitively that something unknown is happening in this zombie hazard.

I had a feeling that something was missing. If there are players and a game system, shouldn’t there also be a game clear?

G-A-M-E-C-L-E-A-R-S-H-O-U-L-D-N-O-T-I-T-B-E-P-O-S-S-I-B-L-E-?-

When I asked Ai about the possibility of the zombie hazard being resolved, she definitely said:

–“0.01% or less.”

It’s not zero. It’s not zero!

In this terminal situation where the world is overflowing with zombies, there is definitely a way to resolve the zombie hazard.

Remembering the sense of accomplishment I felt when I cleared the No Hope difficulty in “DL4,” I shiver.

If I investigate what’s happening in this zombie hazard, maybe I can have more fun with the given game system?

Thinking this far, I shook my head as if I had come to my senses. No, no.

To clear No Hope, Chihiro-kun and I died thousands of times. In the real world, if you die once, it’s over, so I can’t take such a risk.

It’s okay, I’m a normal human being. I won’t put myself and the person I love in danger like that, with a game-like mindset.

Yes, it’s okay, it’s okay. I’ll keep fighting to survive and live in a quiet place somewhere.

As I tell myself this, I become obsessed with watching the video over and over again.

To survive, I need to keep gaining skills with Yume-nee. I’d like to increase the survival rate by adding more team members.

Also, there might be other dangerous buildings like Tokyo Sky Tower. I’ll probably need to gather information.

I need to strengthen my combat power, gather information, and then–.

“……Ritsu-kun, are you smiling?”

Yume-nee, who had somehow woken up, was looking at me fearfully.

I put my hand to my mouth.

My mouth was unconsciously turned up at the corners.
