My Reality Became a Zombie Game World, but Only I Can Use the Game System

Chapter 14: Yume-nee and Infirmary Sex ♡

We could also purchase hot water from the store, but fortunately, this was the infirmary. Since there were facilities and supplies, we were able to easily prepare hot water in a bucket and towels.

When we were both ready, I took out the immunity activation drug from the inventory. I put the tablet in my mouth and swallowed it.

In this state, if I ejaculated inside Yume-nee, immunity to zombification would be passed on to Yume-nee. Imagining the act with Yume-nee, my penis twitched with anticipation.

Yume-nee helped me take off my clothes on the bed.

It was a familiar movement for both of us. In fact, Yume-nee had helped me change clothes many times before. I had never taken off my underwear, though.

First, Yume-nee wiped my chest and abdominal muscles from the front, as I was in my underwear. Yume-nee’s slender fingers crawled over my body, making me shiver.

“You’ve become so strong, Ritsu-kun, without me noticing… Hmm? Aren’t you a little too strong?”

Yume-nee tilted her head. When I looked down at myself, I could see that my body was indeed muscular all over. It was a body that had been trained to perfection, as if I had been training every day.

“This might also be a change that came with becoming a player. My physical ability has increased, too.”

“I-Is that so? You’ve also grown a little taller, haven’t you? I’m a little nervous seeing Ritsu-kun becoming an adult.”

Yume-nee wiped my body with a warm towel, with a shy expression. The warm feeling of the towel was pleasant.

After wiping my face and feet, Yume-nee’s gaze moved to the bulge in my crotch.

Once the act began, the embarrassment of being seen in my private parts was overshadowed by the excitement of wanting to move on quickly.

I took off my underwear boldly, and I stood in front of Yume-nee, who was sitting on the bed, showing off my erect penis. Yume-nee trembled, but she looked at the meat spear with interest and excitement.

“Yume-nee, wipe this, too.”

“Um, yeah… It’s big, isn’t it? Will it fit even though it’s my first time… Wow, it twitched.”

I knew that Yume-nee didn’t have a boyfriend, as we talked together every day, but knowing that she was a virgin made me even more excited.

Yume-nee wiped my private parts carefully and gently. The feeling of Yume-nee’s fingers through the towel made my penis even harder. Yume-nee’s fingers kept grasping my penis, as if to check its size, probably imagining the insertion. Just that alone felt good, and my waist trembled.

“Hehe, it looks like you’re enjoying it. Ritsu-kun, this is the first time for you, too, right?”

“…………….. Yeah, of course.”

“What was that pause? You can’t lie to Onee-chan.”

“Ahh, Yume-nee, you’re gripping too hard, wait, wait, wait!”

Yume-nee strengthened her grip on my penis. Although she seemed to be smiling, this was the expression she made when she was angry. Ahh, if she squeezed any harder, it would be crushed!

“No, no, Yume-nee, I had a little bit of a naughty feeling with Chihiro-kun before, but we didn’t go all the way! We just touched each other a little!”

“Chihiro-kun is the friend you often play games with, right? She’s a girl. I didn’t put her on my caution list…”

“Yeah…… Will you forgive me, Yume-nee…?”

“Hmm, I’ll take your first time, right? Onee-chan’s Verdict of your trial is… Guilty, but barely.”

It seemed that I was forgiven.

By the way, Yume-nee was the prosecutor, the lawyer, and the judge in the Onee-chan Trial. There was nothing I could do. I didn’t want to remember what happened when I was found guilty before.

I was relieved that I was forgiven, even though I didn’t understand what was wrong with me, after thinking about it calmly.

I wanted to change the flow now. Also, I couldn’t wait to touch Yume-nee’s body. I whispered in Yume-nee’s ear.

“Yume-nee, next, I’ll wipe you.”

“Um, yeah… if it’s Ritsu-kun, you’re free to look…”

Yume-nee, with a shy expression, hesitantly took off her blazer, blouse, and skirt.

Why is it so erotic to see a girl take off her clothes? Maybe it was because I was the only one allowed to see her precious body, which she had never shown to anyone else.

Even when I saw her white underwear, I was extremely aroused, and when she tried to take off her bra, which covered her ample breasts, I was already about to ejaculate.

“Ritsu-kun, I’m embarrassed… Don’t look too much…”

“Yeah…”

I nodded obediently, but there was no way I could take my eyes off my beloved childhood friend doing a striptease.

Eventually, the bra was removed, and her white and ample breasts were exposed. Yume-nee squirmed shyly, and the bulge, which had a weight that made it wobble, was fully visible. Even the small pink nipples were visible.

“So big. I feel sorry for Girl K, who was boasting about her D-cup.”

“I can hear you, Karamine-kun! I’m still growing, I told you!”

Kenzaki-san shouted from behind the curtain. Wasn’t she supposed to be blocking her ears?

Her voice was strangely close, as if she was peeking through the gap in the curtain, but I was so focused on Yume-nee that I didn’t care.

I approached Yume-nee, who was now wearing only a simple white pair of shorts, with a warm towel.

“Yume-nee, can I wipe you? Can I, Yume-nee?”

“Yeah. Fufu, it’s kind of nostalgic.”

“Nostalgic?”

“You know, we used to take baths together until we were in elementary school? Even then, my breasts were already starting to grow, and you kept looking at me furtively. You even tried to touch me subtly, without me noticing.”

“Kill me…!”

It was an episode that I had when I was still a child, but I had never thought that Yume-nee knew about it. It seemed that Yume-nee had forgiven the naughty boy who was trying to touch her naked body with a heart like a bodhisattva.

Yume-nee whispered in my ear, and her breath touched my ear, making me shiver.

“I’ve been thinking that since then. If you had told me honestly, I would have let you touch my breasts as much as you wanted.”

“Yume-nee…”

“Ahh… Nn…”

Almost attacking, I began to wipe Yume-nee’s body.

Wiping with a towel was just an excuse, and while I wiped Yume-nee’s body with the towel in my right hand, I was firmly groping her breasts with my left hand. The girl’s flesh, which was unbelievably soft, sank into my fingers endlessly. I was obsessed with squeezing her breasts, which were so big that they didn’t fit in the palm of my hand.

“Nhaa… N… Hiu… Nn…”

I couldn’t help but enjoy hearing Yume-nee’s small, erotic sighs in response to my caresses.

Her skin was sensitive, and she seemed to enjoy the feeling even when I wiped her arms and legs.

“Ritsu-kun… Nn… Stop… You have to wipe my body properly…”

“Yeah.”

I regretted that Yume-nee’s sweat smell was getting thinner every time I wiped her body. When I pressed my nose against her neck and sniffed hard, a sweet smell that excited men wafted.

“Ah, no… Mou…”

Yume-nee, who noticed that I was sniffing her, laughed and squirmed.

Even though I was groping her breasts, stroking her butt, and sniffing her, she allowed me to do so without any restraint. The atmosphere of the girl, who allowed me to do all that, made me feel strongly that we were already having sex.

When I gently rubbed her small pink nipples, Yume-nee reacted strongly. Her wavy pink blonde hair swayed.

“Nhu… Ahh… Hh… Yan…”

Looking at Yume-nee’s face, which was enduring the pleasure, I really thought she was a beautiful person.

A girl who attracted the attention of men just by walking with me. I had seen her being confessed to by school boys many times.

Such a person was showing me her naked body. She was letting me touch her precious body.

I was exposing Yume-nee’s naked body, which all the boys in the school wanted to see. It was incredibly exciting.

I wanted to see this girl get even more wild. I wanted to devour her beautiful body.

My desire knew no bounds.

After enjoying Yume-nee’s softness while wiping her whole body, I finally reached for her shorts.

“I’ll take them off.”

“Ah, that’s…”

I took off her shorts halfway, and a liquid thread was drawn between her crotch and the shorts. It was love juice.

My eyes were glued to the wet slit. The pink blonde pubic hair, the same color as her hair, was very thin, and it couldn’t hide the shape of her genitals.

This was Yume-nee’s pussy. And it was wet because of my caresses.

The twitching meat, which seemed to be waiting for my penis, looked like a hole that existed only to give me pleasure. What is this, it feels too good!

I couldn’t wait any longer. I wanted to connect with Yume-nee as soon as possible.

As a player, I was strong. Gently, carefully, so as not to hurt her, I pushed Yume-nee down.

Yume-nee smiled seductively, as if she had seen through my excitement.

“Ritsu-kun, you’ve made it so big. Do you want to enter Onee-chan’s body? It’s okay, Onee-chan will be gentle with you. Onee-chan will rub your penis in her precious place and make you feel good, and you can ejaculate as much as you want.”

“Yume-nee…”

“Ahh… Nuh…”

I couldn’t hold back any longer, and I pressed the tip of the meat spear against Yume-nee’s slit.

Then, I sank it into Yume-nee’s vagina.

The hot, slimy hole was very narrow, and even though it was well-lubricated, it tried to push out my penis, as if it was resisting. I was excited by the hardness of the virgin meat, and I advanced my penis, loosening her vagina.

“Nuh… Fuh… N, Hian…”

Yume-nee’s voice included a sensual tone rather than pain. She opened her legs wide to receive me.

“Nnhhh… Ahh… N, Nnh… Uhm, R-Ritsu-kun?”

“What’s wrong? Does it hurt?”

Yume-nee started talking so I stopped my movement. My penis was almost completely embedded, and the wriggling folds gave me pleasure.

“No, no,” Yume-nee shook her head to the side. It seemed she wasn’t in pain. Yume-nee had a never-before-seen expressionless face, and her body was limp. Her body, which was dyed pink with excitement, was lewd.

“Actually, I wanted to lead, but I don’t think I can… It feels too good, I’m about to come…”

“Yume-nee…”

“Ahh… Nn… Yan, N-No… D-Don’t move so suddenly… Nhhh♡”

When she said such cute things, I couldn’t stop anymore.

I eagerly thrust my hips, devouring Yume-nee’s vagina. The honeypot, which entwined with my penis in response to my movements, was a hole that existed only to give me pleasure. What is this, it feels too good!

“Ahh… Hia… Nn, Iyahh, Nooo, Ritsu-kun… Nn…♡“

I felt the greatest sexual excitement in my life.

It wasn’t just because it was my first time. Since yesterday, I had been fighting zombies while being aware of my death many times. The danger to my life had made me want to connect with the people important to me, and that desire was dominating my whole body.

“Hiah…♡ Nn…♡ Yaah… Nn… A-Amazing… It feels so good… Ritsu-kun… Aahh♡“

Yume-nee was the same. She moved her waist as if she was offering her pussy hole to me, and she rubbed against me. The survival instinct was turning the usually rational Yume-nee into a bitch who was submissive to my penis.

Because of the danger to our lives from the zombie hazard, we were having the best sex that we would never have known otherwise.

In the infirmary, our breaths, the sound of flesh hitting, and the sound of body fluids scattering echoed. Kenzaki-san could probably hear it, but I didn’t care. I just wanted to devour the body of the girl in front of me. We were just obsessed with each other’s bodies, and we obtained pleasure from the instinctive and animal-like mating.

We kissed each other without saying a word. At first, it was just a touch, but soon, it wasn’t enough, and we twisted our tongues into each other. Yume-nee tried her best to receive it, and she entwined her tongue with mine.

“Nnh… Chu, Juruh, Nnnh♡… Nchuh, Ju, Nnchuh…♡“

I was stealing the first kiss of a girl who had been the object of desire of all the boys in the school. And we were doing it while rubbing our genitals together. The act of attacking both the upper and lower mouths at the same time made Yume-nee’s body tremble with pleasure, and my sense of conquest was fulfilled.

While kissing, I hugged Yume-nee, crushing her. I could fully enjoy Yume-nee’s soft body with my whole body. Yume-nee’s huge breasts, which were pressed against my chest, changed their shape, mnyumyumu. Such a lewd body, which was made to squeeze sperm from men, was now mine.

The sweet body odor mixed with the smell of sweat and love juices was something only I, who was raping Yume-nee, could smell. None of the male students at school could smell it, the scent of a female in heat, which attracted males, and I inhaled it deeply, my excitement accelerating.

When we parted lips, Yume-nee screamed, overcome with emotion.

“Hiaaaahhh… Yah! ♡ I can’t, I’m cumming… Ritsu-kun! S-! ♡ I’m sorry! ♡ I’m cummingggg♡“

Yume-nee reached her climax easily, and her vagina tightened. The complex folds, which begged for semen, entwined with my penis, feeling good. Yume-nee, who had reached her climax, was shaking all over, overwhelmed by the intense pleasure.

“N… A… ♡ Fufufu, fufu, nnnn… ♡”

After the long wave of pleasure passed, Yume-nee, with a dazed expression, became limp. Her gaze was unfocused, and tears were flowing from the corners of her eyes, overwhelmed by the pleasure.

To be honest, it was unexpected.

I had thought that my first experience with Yume-nee would be that she would gently lead me, and I would reach my climax first. I had never imagined Yume-nee being so overwhelmed.

But this was reality.

I was the one who devoured Yume-nee, and Yume-nee was the one who was devoured.

I was the one who raped Yume-nee, and Yume-nee was the one who was raped.

The sight of Yume-nee, who accepted this hierarchical relationship and was immersed in pleasure, took away my reason.

“I’m sorry, Yume-nee. I’ll continue.”

“Nhi! ♡ No, not yet! ♡ Yaah! ♡ No, Ritsu-kun, hin! ♡ I’m gonna cum, I’m gonna cum right now! ♡”

For the first time, Yume-nee showed a gesture of trying to escape. The body of a virgin, who was experiencing incredible pleasure for the first time in her life, was trying to escape instinctively.

I forcefully pinned Yume-nee down from above, and just for the sake of my instinct to ejaculate, I violently raped her vagina with my penis.

“No, Ritsu-kun, I’ll break, I’ll break… Hin! ♡ Ah, no, I’m cumming, I’m cumming! ♡ ~~~~~~!”

I accelerated towards ejaculation, crushing Yume-nee’s body, which had reached climax multiple times.

I made my penis go back and forth in Yume-nee’s vagina repeatedly.

At first, Yume-nee tried to escape, fearing pleasure, but after repeated climaxes, she lost her strength, and she became limp, accepting my penis like a female.

Even in this state, Yume-nee’s vagina clung to my penis without any gaps, giving me the ultimate pleasure. The movements of her vagina, which assured me that the best ejaculation was waiting ahead, made my movements more intense.

When I forced my tongue into Yume-nee’s small mouth, which was moaning with pleasure, she happily entwined her tongue with mine.

I wanted to make Yume-nee mine. I wanted to pour my thing into her womb.

As a male’s instinct, I raped Yume-nee’s vagina with my penis to my heart’s content. The limit was near.

“I’m gonna cum, Yume-nee.”

“Hia! ♡ Ahh, yaah! ♡ N, hiu, ya, a, a, a, hin! ♡ I, I’m cumming… I’m cumming… ♡”

It seemed that Yume-nee couldn’t hear my voice anymore. She just opened her legs, making it easier for me to rape her, and she was moaning.

Crushing Yume-nee’s body, enjoying the feel of her female body, I released my semen into her deepest depths.

My waist was about to give out, it felt so good.

I wondered if all the ejaculations I had experienced until now had been fake, as an incredible pleasure ran through my whole body.

“~~~~~~~~~~~~~~~♡♡♡”

Yume-nee was also experiencing an orgasm that she didn’t know how many times it was.

With an expression of pleasure that was unimaginable for Yume-nee, she shook her waist and squirted, her body melting in pleasure. There was the sight of a lewd female, who had had fulfilling sex, in the aftermath. I felt a sense of satisfaction that I had made Yume-nee look like this.

Yume-nee’s body, which was trembling with a shudder, had completely lost consciousness.

To be honest, I still wanted more, but I couldn’t force Yume-nee any further. I pulled out my penis, and the white liquid, which was evidence that I had dominated Yume-nee, overflowed from her slit. I must have rubbed a weak spot when I pulled out my penis, as Yume-nee squirted and moaned again.

“Hiaaaahhhhhhhhhh♡”

I wiped Yume-nee’s body with a towel and covered her with a blanket.

Looking down at my body, my penis was still painfully erect, even though I had just ejaculated.

If it was the usual me, it should have been flaccid by now. Something was wrong.

Come to think of it.

I remembered that items in the “Dead Land” series that required intercourse had the effect of an aphrodisiac.

Maybe the immunity activation drug also had such an effect.

I still wanted to ejaculate desperately.

Fortunately, I had a girl in mind for the next one. I suddenly opened the curtain that separated our bed.

“Kya!”

Kenzaki-san, who had been peeking through the gap in the curtain, was surprised and fell on her butt.

Her tights and panties had slipped down to her knees, and when she fell on her butt, her skirt was flipped up, and her slit was about to be exposed. It was obvious that she had been masturbating while watching me and Yume-nee.

“Ah, yah! T-This! I-It’s not what you think!”

Kenzaki-san, who was blushing with shame from being caught masturbating, was on the verge of tears. Her chest was also exposed, as the front of her blazer and blouse was open, and her bra was slightly askew.

She was in a hurry, and the tights that had slipped down to her knees were getting in the way, so Kenzaki-san was showing me her provocative figure in full. I stared at her fair skin, which was usually hidden, and swallowed my saliva.

This was Kenzaki-san’s fault for inviting me like this.

“Eh… Karamine-kun? Kya!”

I picked up Kenzaki-san as she was and gently placed her on the empty bed on the corridor side.

I hugged her from behind and pressed my penis against her small and cute butt, through her skirt. I hugged her so she couldn’t escape, and I whispered in her ear.

“You’re interested, aren’t you? Do something about this.”
