In the room next to mine, there lives a naughty older sister.
It's been three months since I graduated from an ordinary high school. The season has changed from the warm spring with cherry blossoms dancing in the air to the summer where a towel and a drink are essential when going outside.
Not being academically gifted, I live alone in this apartment, which is about an hour by train from the mid-tier private university I got into.
"It's so hot..."
Today, I only had classes in the morning, so here I am, looking up at the sun in front of my apartment, even though it's not even 1 PM yet.
It was located in a corner of the countryside that had been slightly developed, with commercial facilities and the like in the center of the city.
I wiped the sweat from my forehead with a towel, then thought to myself, 'I'll just hurry up and take a shower in my room,' and walked on.
However, immediately--someone tapped me on the shoulder.
When I turned around, I first saw the finger that tapped my shoulder. A slender finger, pure white and transparent.
Slowly, I turned completely around and greeted the person.
"Hello, Hashimoto Misuzu-san."
"Hello, Tomokazu-kun. You are early today, aren't you?"
"Yes... I only had classes in the morning. I didn't have any club activities or shopping, so I had no choice but to go home."
"I see."
Smiling softly, she naturally came to stand next to me, this beautiful girl.
Her name was Hashimoto Misuzu. She was a very cute and wonderful older sister who lived next door to me.
She's about three or four years older than me. After graduating from a junior college, she started working as a kindergarten teacher. It seems that her workplace takes care of children on weekends as well, today she has a day off.
"It's hot, isn't it? Just going shopping for a bit made me all sweaty."
"…"
"That's why I hate summer. …Are you listening?"
At that moment - the sharpness of Misuzu-san's pretty eyes as she glares sweetly at me sends shivers down my spine.
Misuzu-san is... very naughty.
Her refined features hinted at the care and love her parents had showered upon her. Her jet-black, straight hair emitted the scent of shampoo. Her eyes, like blue jewels that suited summer so well, were pure and innocent, yet the fact that I found something indecent in them might be due to my own perception—or perhaps, my desire.
...The best part is Misuzu-san's figure.
The sweaty neck flows down to the collarbone, and then the next thing you see are her plump breasts.
Looking slowly at her breasts, I gradually move down and am captivated by her slim waist, which contrasts sharply with the rest of her body.
However, as expected of a woman -- she has hips that are perfect for childbirth, and a firm butt that sticks out.
To a man like me, this perfect body wrapped in a pure white mini dress -- is more ferocious than the summer sun.
"You seem a bit nervous today, Tomokazu-kun."
"Not at all..."
"Eh, is that really true? You're shaking like you're scared, and you're walking slowly."
"It's because... it's hot... and I'm tired..."
"Hmm."
I hastily look away from Misuzu-san's plump thighs as she walks next to me.
I had been looking at the neighboring house for a while… but I couldn't resist the sweet body odor that wafted over, and I glanced at her chest again.
94cm. Her bra size is G. Ahh--I know I shouldn't look, but I can't help but stare.
Her breasts bounced and jiggled with each step she took.
She captivated me with her erotic movements, almost to the point that I wondered if she was shaking them on purpose.
"You're looking at my breasts too much..."
--She whispered.
As we approached the exterior stairs of the apartment, Misuzu-san whispered in my ear to warn me.
I covered my mouth with my hand and quickly removed my gaze, even though I had not spoken anything.
Misuzu-san's whispering voice was different from her usual pure tone.
It was the voice of a female inviting a male. My ears were caressed, my brain was tickled, and a sticky warmth spread down to my lower abdomen.
I... could no longer stand and walk straight.
Hunched forward pathetically and panting heavily, I followed Misuzu-san up the stairs.
And finally, we arrived in front of Misuzu's room.
My room was one door down, so I shouldn't have stopped in a place like this and should have kept moving, but I couldn't.
With a clang, Misuzu-san opened the front door.
A wet, lewd air leaked out from the room, probably containing the smell of Misuzu-san's underwear, my breathing became heavier, and I found myself letting out a voice that sounded like a cry.
"What's wrong? Tomokazu-kun's room is over there, right?"
"... Misuzu-san..."
"--Hmm? What? Did I do something? Come to think of it, I invited you or something. I forgot."
"Ah... last night... a message..."
As I stare at Misuzu's chest, who is giggling like a little devil, I reminisce about last night.
Last night--my smartphone, which is usually still and doesn't move much because I don't have many friends, vibrated.
When I timidly opened the screen, I found a message from [Misuzu-san].
[Good evening♪ A present for Tomokazu-kun from Misuzu-san, who is bored while her boyfriend is away on a trip♪]
[Image sent. Please launch the app to view.]
We exchanged contact information when I moved here, but this was the first time I had actually received a message.
With a pounding heart, I opened the messaging app and there it was――
"You asked if I would like to come to your room tomorrow? I... well, I... wanted to..."
"--Ah, that's right. Hehe."
It was a selfie of Misuzu-san wearing a loose shirt.
Misuzu-san's eyes were covered with her hands, and my gaze was drawn to her lasciviously smiling lips.
Her cleavage was clearly visible, and there were drops of water on her chest, probably after she had taken a bath.
It was a selfie of Misuzu-san sitting flat on the tatami mat in a girl's position... a casual everyday scene.
In the photo, Misuzu-san was holding a small note that said, "Do you want to come to my room tomorrow afternoon?". It also said, "I'll do something nice for you."
...Then, the memory of masturbating ran through my mind with ferocious force.
Last night, just Misuzu-sans's selfie had made me ejaculate four times.
What was spat out into the tissue wasn't my pure feelings for Misuzu-san, but simple sexual desire.
It was so humiliating and frustrating that I'm still troubled by it...even now.
But strangely enough, all those worries and conflicts were blown away in an instant when Misuzu-san took my hand.
Our sweaty palms stuck together and she pulled me close.
"...Okay. I'll take your virginity."
Clang--The front door closed, and Misuzu-san quickly locked it.
In an instant, a private summer room just for Misuzu-san and I was completed. I think she could even hear the sound of my heart beating.
My mouth was dry. My hands and legs were trembling. My knees felt like they would give way at any moment, and my eyes went back and forth between Misuzu-san's lips and chest...
--I'm a virgin.
I've never had a girlfriend since I was born, and the last time I held a girl's hand like this was probably on an elementary school field trip.
So it was obvious that I was nervous, almost to the point of being embarrassing.
My fingertips were trembling...Misuzu-san must have noticed, as she said, "You're really a virgin, aren't you?"
Maybe to reassure me, Misuzu-san hugged me gently, but...I flinched...
"Ah...Did that make you even more nervous?"
Ah... was this also part of her plan?
Misuzu-san's cunning words and expression made me nod obediently, "Yes..."
※ ※ ※
A pink futon was already laid out in the room.
Misuzu-san and I were sitting facing each other on the futon, and now I was massaging her breasts.
First, I tried to lift Misuzu-san's breasts from below to check their weight.
They were heavy and warm, and the space below her underboob was stuffy...
"Amazing... breasts..."
Next I grabbed her from the front. After properly asking Misuzu, "Can I massage you like this?"
The breasts supported by the bra were unexpectedly firm and elastic and felt more responsive than I had imagined.
For me, who had never touched a girl's body before... everything was new and erotic.
Squish--squish-- I kept rubbing her breasts. For example, a man who was used to dealing with women would touch them in a teasing way, gently caress her nipples, and talk to her to liven up the mood, but I... was just rubbing her breasts for my own satisfaction.
"Is it okay to just rub them?"
"Eh...?"
"Anything else you want to try? ...This is a rare chance, you know?"
"Okay, then...Can I try putting my finger in your cleavage..."
"Hehe, what's that...Sure."
Losing to Misuzu-san's smile, I inserted my index finger deep into her cleavage.
Soft pressure from both sides. Steamy air had accumulated between her breasts.
I left it inserted for about ten seconds and then pulled it out, and it felt like Misuzu-san's moisture was clinging to my finger.
"Uhh... Misuzu-san..."
"Ah. I thought you'd do this..."
Unable to hold back any longer, I buried my face in Misuzu-san's breasts.
Misuzu-san was a little annoyed, but she continued to stroke my back gently... it made me so happy that my brain melted.
I sniffed the scent of the deep cleavage where I had just inserted my finger.
Next, I stuck out my tongue and licked it, Misuzu-san's hand rubbed against my crotch over my pants.
"Ahh, Misuzu-san... uh, uh, fuh... fuuh..."
Before I knew it, I was shaking my hips back and forth against Misuzu-san's palm.
Clinging to the steamy, deep-bottomed mass of motherhood, I shook my hips back and forth awkwardly... I continued to thrust like a dog in heat...
Even if I ejaculated like this, I wouldn't even be able to cum on Misuzu-san's hand.
In the silent, closed room, only the sound of friction echoed.
My meaningless hip movements wouldn't even get a girl pregnant.
When Misuzu-san said, "Let's stop now," I finally stopped and looked up.
"Haa, ah... Misuzu-san...?"
"I guess you've relaxed a little. Wow, my breasts are sticky... you drooled quite a bit, didn't you?"
"S-sorry... um..."
"Hehe -- now it's your turn. Let me see Tomokazu-kun's penis."
"What? Wait, Misuzu-san, wait, ah...!"
A soft white hand stretches out, and in an instant my pants are pulled down, leaving me in just my underwear.
Needless to say, I've already formed a small tent.
Misuzu-san licks her index finger, then puts her hand on my trousers and pulls them down.
"Wow. It's big... But it's still a virgin, what a waste."
"Is that so...?"
"Yeah. It's bigger than my boyfriend's. It looks like the guys I see in uncensored adult videos."
"I-I see..."
I don't know the average size, so I'm at a loss for words.
I don't watch much porn, either. Lately, I've been masturbating every night, thinking mainly of Misuzu-san. I'd lie on my futon, picture Misuzu-san's gentle smile, rub my erect penis, and squirt my semen into a tissue. ...I'd always end up moaning, "I'm sorry."
While I was remembering how I masturbated to Misuzu-san, my upper body was also stripped naked.
Meanwhile, Misuzu-san had a lotion bottle in one hand.
She popped the lid open and squeezed out the lotion.
Her pure hands were stained with obscene mucus... As I felt a strange loneliness and pain in my heart, her hands came to my chest.
"... Your nipples feel good, don't they? Even boys can feel it."
Misuzu-san's lotioned fingers pinched and caressed my nipples.
She traced my areola teasingly, and when my spine twitched, she started to play with my nipples again.
"Haa, haa, um, Misuzu... this is dangerous..."
"Mmm, ah, ah. Your nipples are slippery."
"Ah, ah. No, ah... uh..."
Aren't nipples just erogenous zones for girls... I wondered, but my body was already filled with pleasure from my nipples.
Every time Misuzu-san teased me, I had the illusion that she was licking the depths of my loins with her hot tongue.
Slowly, pre-cum began to overflow from the tip of my cock, soiling Misuzu-san's futon.
I don't know what she thought about that, but before long, her lotion-covered hands wrapped around my cock and she started squeezing it hard.
"Oh, no... it feels good, Misuzu's hand... ah, ah..."
"Yes, yes. My boyfriend has been training me a lot. When I rotate it like this, it makes a squelchy sound..."
"Uh, ah! Ah... ahh...! No, no..."
"Ah, don't pull back. See? The tip is so sensitive, Tomokazu-kun. You're a virgin after all."
Her slippery hand stimulates my cock, squishing and stimulating it, as if she were repeatedly twisting a doorknob. When her whole palm rotates and stimulates the shaft and head, I can't help but pull back my hips.
But Misuzu-san grins and reaches out even more, refusing to let go of my cock.
"Tomokazu-kun, don't you like any girls at university?"
"I, ha... ah, Misuzu-san... ah..."
"I can't hear you well. Did you say you like me?"
"Ha, ah... stop, I'm cumming, I'm cumming... um, Misuzu-san...!"
"N-- Oops... that's dangerous..."
Misuzu-san's hand suddenly let go.
I felt the pleasure that had risen to the brink of my limit slowly decrease.
"If you let it out here, you'll never lose your virginity."
"Haa... I'm sorry..."
"Yeah. -- It's not easy to cum two or three times in a row like in erotic manga. Be careful, Tomokazu-kun okay?"
"Y-Yes... Misuzu-san..."
"Hehe. Good boy, good boy."
As if in sync, Misuzu-san and I embraced each other.
Her body was fertile, like a goddess. Buried in her softness that seemed to embrace me completely, my stimulated penis was pressed tightly against Misuzu-san's lower abdomen.
The fabric of Misuzu-san's mini dress rubbed against the underside of my penis... and I started to move my hips again.
*Dent-Slide-Dent-Slide*
I was spoiled by Misuzu-san's kindness in accepting a pathetic me.
"Do you want to suck them?"
When she asked me that, I slowly moved my face away, and Misuzu-san freed her proud breasts.
Marshmallow-like breasts that matched the whiteness of her Mini One-piece dress.
I nodded silently and then sucked on her nipples. ...As usual, I kept moving my hips.
"You're like a dog. All you're doing is moving your hips...are you trying to have sex with me?"
"Uhh...I'm sorry...I'm sorry..."
"You're like a kindergartener now. --Okay, okay, let's lie down for a bit, Tomokazu-kun."
"Eh..."
At Misuzu-san's urging, I lay on my back on the futon.
Then Misuzu-san leaned over me and laughed.
Then she stuck out her crimson tongue erotically, bent down, and sucked my right nipple.
Dripping saliva, she moved to my left nipple, which she sucked in the same way.
"Ah, ah... it feels... good..."
My spine arched involuntarily. In tandem, my hips rose, and my erect penis slapped against Misuzu-san's stomach.
As if that didn't matter - she continued to lick my nipples as if she was amused by the way I reacted.
Misuzu-san's tongue continued to crawl all over my body. My solar plexus, my sides, my lower abdomen... and then my groin.
The moment she kissed my groin, I was overcome with a kind of pleasure I had never felt before, and an electric current ran from the back of my head to my tailbone.
"Misuzu-san... ah, ah... it feels good, really, ah..."
"You've been saying the same thing for a while now, haven't you? Kiss, kiss--"
"But... ah, stop, p-mm, mm...!"
"Ah, you're feeling it so much. You're so sensitive... So, if I were to suck your dick in this state... ha, mmm"
"! Blowjob, y-y-y...?!"
She opened her mouth with a string of saliva and swallowed my dick.
After sucking just the tip, she slid all the way down to the base...
If I closed my eyes, I only felt a strange lukewarm feeling. But once I opened my eyes, I realized that it was Misuzu-san's mouth, the pleasure doubled.
She stared at me and sucked my cock with a gulck.
Her tongue, covered in saliva, licked up the underside of my penis, while her cheek meat stuck to my glans...and the air in her mouth was intentionally sprayed against me...
"Gubbupo, bobu, pububuu, buch."
A slow blowjob of the Netori type.
Normally foreplay is something one enjoys for a long time, but I already felt like I was going to cum...
She looked at me with a teasing gaze she continued the blowjob.
My seminal vesicles were twitching, and the semen I had been storing rose up... Ah, it's cumming out, it's cumming out... I'm sorry...
"---Kyaah...! Tomokazu-kun...?"
I twisted my body, pressed my face against the futon in embarrassment, while pushing my hips up and ejaculating.
Spurt, spurt, spurt. The semen flew out in a parabolic arc, splashing down on my stomach.
I had only just been warned to be careful, but I had already ejaculated.
All I needed to do was ask her to stop with the blowjob because I was about to ejaculate...
Regretting my poor communication skills and vain personality... I let out the last drop...
"Ah... You're kidding... You already came...??"
Misuzu-san, who reflexively avoided my semen, had a... strange expression on her face.
It could be interpreted as an exasperated look, or a sad look.
- "If you're going to come, you should say so properly," she scolded me in a low voice, and my heart, which had been excited just a moment ago, deflated.
The hands of the clock in the room ticked away, and an awkward moment passed.
A virgin, premature ejaculator, a man who can't say what he wants to say... what would Misuzu-san think of me...?
On top of that, if she found out that I had masturbated to Misuzu-san's sexy selfie last night... I'm sure it would all come crashing down...
*Kiss* I heard a lip sound, and a delayed electric current ran through my body.
To my surprise, Misuzu-san was kissing my groin while holding my flaccid penis.
An electric current of pleasure was generated from my overly sensitive penis, reverberating inside my body and gathering at my penis.
"Ah, ah... uh, ah... aaah... ah..."
"Mmmm, kiss... kiss, kiss.... It's getting big already."
In Misuzu-san's hands, my penis had revived.
"Misuzu-san... your boobs..."
"Oh, my boobs... a titty fuck?... Is that okay before we have sex? Aren't you going to cum again?"
"I won't... I won't, I... absolutely not."
"Hmm... that's a promise you made to me, your big sis? -- Here you go."
After Misuzu-san took off her mini dress and underwear, she poured lotion into her cleavage, which she boldly opened.
I stirred her cleavage with both her breasts to make it easier for my penis to slide, and then I opened it again with a whoosh.
A paradise realm, knotted with countless threads.
I squatted down and pressed my penis against Misuzu-san's cleavage.
--And then, her breasts pressed against me from both sides. Pressing, sealing me shut. It was practically like being inside a vagina.
"It's amazing... It feels so good, Misuzu-san, Misuzu-san...!"
"--Ah, -- Wait, mmm, mmm... You have to calm down, or else..."
"Haa, haa, haa, haa... uh, uh..."
I was so absorbed that I started shaking my hips. Back and forth... and back....
Misuzu-san's pure face and black hair-- her big breasts that were squeezing my penis from both sides.
Every time my hips slammed into Misuzu-san's breasts, her breasts rippled.
I felt like I was having sex.
I moved my hips thinking of Misuzu-san, and it felt good...
--Misuzu-san always greets me with a smile.
If we happened to meet as I was leaving my room to head to university, she would say goodbye.
Just that was enough to make me think of nothing but Misuzu-san all day.
She has an innocent, pure aura. Healthy, plump legs. An angelic smile.
But then one day, I saw a photo of her and her boyfriend.
It was then and there that I realized that this wasn't just admiration, but love. And I felt like I'd been betrayed.
I don't know why.
From that day on...to me, Misuzu-san has become both the object of my affection...and my sexual desire.
She occasionally sends me selfies. I spit out semen while thinking of Misuzu-san in the neighboring room.
Feeling my own patheticness, I can't help but let out a girly voice again...
The feeling of last night's ejaculation comes back to me.
The blank expression on Misuzu-san's face as she clutches her chest is the final push...
"Ah, ah... Misuzu-san...!"
"Wait. Ah... Kyaaah...! M-again... Did you cum...??"
A cloudy white liquid gushed out from between her breasts.
After a quiet mutter, Misuzu-san lowered her hand, my penis was released, and I collapse off her waist.
"Ah... ah... I'm sorry, I'm sorry... I came again..."
The remaining cum oozed from my flaccid penis and dripped onto the futon.
The amount of semen that had soiled Misuzu-san's body was small for the second time, but it still stuck there stubbornly.
...I can't take it anymore.
...Placing my hand on my heart, which was barely beating, I apologized to Misuzu-san again.
As I silently watched my semen being wiped away with a few tissues...I realized once again how foolish I was...
"...Hehe."
Her blue eyes narrowed obscenely as she looked down at me, who was completely exhausted.
I think it was my current state of mind that made me feel uneasy when she casually licked her lips.
"We weren't able to have sex, so unfortunately you'll still be a virgin... Tomokazu-kun."
She whispered into my ear, with an exhale.
Even though I was feeling it, I couldn't even make a sound...only my body trembled.
※ ※ ※
That night, Misuzu-san sent me a selfie as well.
She was holding a condom in her mouth and pulling at the top of her thin shirt...
I can't see her nipples, and her face isn't in the picture.
But it's so erotic that I take off my pants and, breathing heavily like a dog... I start stroking my cock.
My sexual desire is now under Misuzu-san's control.
Looking down on me, teasing me, Misuzu-san sent me selfies according to her mood...and I ended up masturbating.
"Ah, Misuzu-san, it's coming... inside of you, my... ah... uuh... Misuzu-san, Misuzu-san... I'm sorry... I feel so good... I love..."
I give her a bunch of creampies inside my fantasies.
A bewitching smile comes from somewhere... I put my forehead on the tatami mat in surrender and with a *thump* I spurted out my semen.
