Episode 11: "Premature Ejaculation Improvement Training"
After finishing breakfast, I sat down at my desk and booted up my computer.
It was to continue working on my game.
—One month had passed since Seo-san and I exchanged our virginities.
Since then, we had been living a life completely immersed in sex. Not a single day went by without us having sex.
We had just had sex this morning too.
For about a week after our first experience, we were like mindless monkeys, forgetting about food and sleep as we just had sex, but recently, perhaps because we had gotten used to it and gained some composure, we had managed to establish a proper daily rhythm while still having sex.
Even so, we absolutely had sex at least three times a day...
Anyway, recently I had started to have some private time again and could focus on my game development work.
As I started operating the keyboard, Seo-san called out to me from behind.
"Hey, heeey~. Yuuki-kun, look over heeere~"
Haa, oh boy...
I was no longer the same pathetic virgin I was a month ago. Even if Seo-san was completely naked or even masturbating in the direction I turned, I could handle it coolly without panicking.
No matter what she was wearing, know that it was now impossible to fluster this non-virgin, Kusano Yuuki!!
"Hmph..."
I turned my chair around with a cool, stylish spin, facing Seo-san with a nihilistic smile on my face.
—And there she was.

Seo-san was there, clad in mysterious, cool-looking armor, striking a triumphant pose.
"Eh!? What's that!? That's incredibly cool!!"
I couldn't help but stand up from my chair and shout.
Yes, the Seo-san before my eyes now was dressed as if she had stepped out of a fantasy world.
The design, primarily silver and black like a knight's armor, was accented with gold trim in places and looked incredibly cool. It was clearly on a different level from ordinary cosplay outfits.
I had never seen such cool equipment before. And the fact that it was being worn by the supremely cute Seo-san made its destructive impact even more immense.
Perhaps satisfied with my shocked expression, Seo-san puffed out her chest and declared.
"It's the Divine Armor, Ravel Dine."
"Th-the Divine Armor, Ravel Dine!?"
What's that!? It sounds super strong and way too cool!!
"It's one of the Thirteen Divine Artifacts bestowed upon humanity by the Goddess Ravelna, a legendary armament recorded in the sacred texts of the Ravelna faith. It's said to nullify all long-range attacks. And apparently, just wearing it automatically restores magical power."
"The Thirteen Divine Artifacts!? Nullifies all long-range attacks!? Automatic MP recovery!?"
Whoa...!? That's totally a cheat item!
And the setting of 'Thirteen Divine Artifacts' totally tickles my chuunibyou heart! There are twelve more of these super cool things!?
That's it! Maybe I should feature this in the game I'm making now? It could work as a weapon used by the protagonists!
No, maybe I should have an enemy character use it? Like, the thirteen strongest warriors belonging to the church are each given one, and they appear in a final battle scenario...
Still, come to think of it, maybe the Holy Sword Ravelion that Seo-san threw away on the first day was also one of the Thirteen Divine Artifacts? What a waste!
But why does Seo-san have such an amazing thing?
Seeing my puzzled expression, Seo-san explained.
"Huh? Yuuki-kun, you haven't been checking the Sacred Items list? The items displayed there change over time, you know? Usually, it's just bugged stuff and nothing shows up, but occasionally rare-looking things like this appear."
Seriously!? I had no idea!
Because Seo-san threw the Holy Sword Ravelion in the trash on the first day, I hadn't checked it since then.
As I gazed at it admiringly, Seo-san promptly took the armor off.
"Well, even if I have something like this, it's completely useless in this room."
Saying that, she tossed the Divine Armor Ravel Dine into the trash can.
"Aaaaaah! Divine Armor Ravel Diiiiiiine!"
I hurriedly rushed over, but it was already too late. The Divine Armor Ravel Dine had vanished from inside the trash can.
As I slumped my shoulders dejectedly, Seo-san, paying me no mind, lay down on the bed and started playing a handheld game.
(Sigh... Well, it's true that having a cheat weapon in a room you can't escape from even by having sex is pretty meaningless.)
I let out a big sigh, sat back down in front of my computer, and immersed myself in game development once more.
Several hours later—
Perhaps bored with her handheld game, Seo-san was quietly watching me work on my game from beside me.
And she would occasionally glance over at me. That gaze felt ticklish and made me somewhat restless.
Lately, Seo-san had started coming to my side even when we weren't having sex. Before, she would stay away so as not to disturb me while I was working, but now, whenever she had free time, she would come close, resting her head on my shoulder and acting affectionate.
(But it's not like she likes me or anything...)
It was probably just loneliness. Although Seo-san and I had had sex over a hundred times now, she had never once told me she liked me.
I had originally admired Seo-san, and being in this room and having sex with her had made me like her more and more, but she was different.
The reason she was having sex with me was simply that there was no one else. I was confident she held more than average goodwill towards me, but that was likely not romantic feelings, but merely those of a classmate and friend.
To put it harshly, I think our relationship was close to what you'd call 'friends with benefits'.
But I was satisfied with that. Originally, we were on terms where we wouldn't even date, let alone have sex—we were just classmates who exchanged greetings in the classroom. Just being able to get this close to her and perform acts like lovers made me happy.
During sex, whenever I got carried away and felt like shouting "I like you!" or "I love you!", I would hurriedly cover my mouth.
If I uttered such words, things would surely become awkward. I wanted to avoid doing anything that might ruin this comfortable relationship we had now.
So, to continue enjoying my time with Seo-san as before, I had decided not to confess my feelings to her. Even though we were in a sexual relationship, I understood that it would be presumptuous to get conceited and think that maybe she liked me too...
Thinking such thoughts, I silently continued my work.
Before I knew it, it was already noon.
In this sealed room with no windows and no view of the outside, it was easy to lose track of time, so we always kept a screen displaying the outside scenery.
The screen showed a clear blue sky. I wondered if we would ever get to see this view directly again...
(It's been over two months since we were locked in here...)
Even for an indoor person like me, I was finally starting to feel the desire to go outside. If I were alone here without Seo-san, I might have gone crazy.
But strangely, being with Seo-san gave me energy. I thought she was like the sun. Because she was by my side, I could keep going.
I closed my laptop and turned towards Seo-san.
"Shall we have lunch soon?"
"Yaaay! Hey, let's have foie gras today."
Seo-san raised her hand happily. Since we could order any high-end cuisine from around the world anytime we wanted, she had become quite the gourmet.
Well, I didn't dislike seeing Seo-san enjoy her meals either.
After we finished eating together amicably, Seo-san led me to the bed. Normally, we would have sex here, but...
"Today, let's do Yuuki-kun's premature ejaculation improvement training, okay? ♡"
Seo-san said while licking her lips.
That's right. Even after over a month of continuous sex and accumulating over a hundred sexual experiences, I still couldn't control my ejaculation.
If I hadn't ejaculated at all beforehand, I would climax within a minute of entering Seo-san's vagina. During the first week, I would explode just from insertion, so this was actually a significant improvement.
Moreover, Seo-san, on the other hand, seemed to have gained control over her own orgasms as she got used to sex, so lately, I was the only one being made to climax over and over.
However, there were several reasons for this, and it wasn't entirely my fault.
The first reason was my own mental issue.
For an introverted, pathetic virgin like me who got nervous just greeting female classmates, sexual intercourse with my admired Seo-san was far too stimulating. So, during sex, my mind would go completely blank, and I would climax immediately regardless of my will.
Especially since being locked in this room, I had been falling for Seo-san more and more. Thinking about her would excite me, leading to a vicious cycle where I couldn't hold back and would ejaculate immediately.
Conversely, for Seo-san, I was just a friends-with-benefits classmate, so she probably didn't experience the same level of mental excitement. I, who had genuinely fallen in love with her, couldn't possibly compete.
The second reason is that Seo-san's pussy is too much of a legendary treasure.
It feels way too good. Unfortunately, as someone with only one sexual partner, I have nothing to compare it to, but I can absolutely assert that it's true.
Seo-san has a body that gets incredibly wet easily, and she produces a lot of love juice. On top of that, the tightness is insane. It wraps around my dick without any gaps, squeezing and gently embracing it. And when she starts moving her hips, it clings to me as if it were a living creature.
Frankly, any guy would fall instantly for a pussy like that. In other words, it's not my fault.
The third reason is that Seo-san's technique keeps improving.
She's not only naturally athletic but also smart. She probably has a natural talent for sex too.
Just when I think I've gotten a little better at holding back, she becomes even more skilled, so I get easily milked every time.
In other words, it's not my fault. It's all because Seo-san is too damn sexy.
"Are you listening, Yuuki-kun? No matter how much of a stud you are, it's no good if you cum that quickly, right? You're not a virgin anymore, you've done it many times now, so..."
"Yes..."
Being scolded for premature ejaculation by the girl I admire is so pathetic it makes me want to cry.
"I do like it when you cum a lot inside me, but you'll be in trouble when you get a girlfriend, won't you? So, let's properly overcome this while we can!"
Her words send a sharp pain deep into my chest.
Seo-san is just worried about me as a friend. I understand that. Even so, it still hurts.
Because it felt like she was implicitly saying that the "her" who would date me wasn't herself.
"What's wrong? Let's get undressed quickly, okay? Or... have you gotten tired of having sex with me?"
Seo-san was looking at me with a worried face. I shook my head and hurriedly denied it.
I wanted to say, "It's the opposite! I like you so much it's causing me trouble!" but there was no way I could say that.
Once we were both completely naked, Seo-san straddled me.
Despite her pure appearance, Seo-san likes positions where she moves herself during sex, like cowgirl or facing seated positions. I also like being taken by Seo-san, so I think our sexual compatibility is amazing.
When our lips met, we shared a deep kiss, intertwining our tongues. Tangling tongues and exchanging saliva. Seo-san's sweet scent filled my nostrils.
How many times is this that I've had sex with Seo-san? It should be countless by now, but my heart still won't stop pounding.
"Alright then, today let's try to last for more than ten minutes just with frottage without insertion, okay? ♡"

Seo-san placed my penis between her thighs and slowly began moving it up and down.
--Squelch, squish, schlick... .
Each time Seo-san moved her hips, her pussy and my penis rubbed together, filling the room with lewd wet sounds.
Honestly, it feels amazing. But, I think I can still hold on. Thanks to being trained inside Seo-san's pussy for the past month, I've become able to somehow endure just being rubbed on the surface.
Matching Seo-san's movements, I also moved my penis, pressing it against her slit. Then, Seo-san's body jolted upward. It seems Seo-san is feeling good too.
"Mmm, seems like you're okay. Let's keep trying like this a little longer, okay? If you feel like you're going to cum during it, you have to tell me properly, okay?"
"Y-yeah"
Then, Seo-san started rolling one of my testicles around with her hand. The sudden pleasure made me let out a sound involuntarily.
Seeing me like that, Seo-san grinned.
This time, she used both hands, gently massaging and kneading them. At the same time, she sped up the movement of her hips.
"Ah, wait a second, Seo-san! I said that's no good!"
But Seo-san didn't stop moving. Her breasts were also jiggling wildly. Visually, it was dangerous too.
(Dangerous! Aaaaah~, I can feel the sperm rising from my balls!)
I desperately try to hold back, but because Seo-san is gently stimulating my testicles with her fingers, the semen accumulated in my testicles is thrashing around, seeking an exit.
I want to be enveloped by Seo-san's pussy. I want to ejaculate inside her. That's what I thought in that moment.
--Splurt! Splurt, spluuuuuuurt!!
Illustration (By Mitemin)
A large amount of cloudy white fluid shot out with force, landing on Seo-san's stomach and chest. By the time the ejaculation ended, her entire body was a sticky mess.
Even though I wasn't inside Seo-san's pussy, I had another accidental ejaculation. I was left dumbfounded.
"Hmm, five minutes. I think you're lasting a lot longer, but I guess there's still room for improvement... Let's try even harder from now on!"
Seo-san said that with a beaming smile, scooped up some of the white liquid on her chest with her finger, and licked it off. That sight was so obscene it got me excited again.
"Ooh? Already back in action? You cum fast, but your recovery is still amazing as ever... Wanna give it another try?"
I silently nodded my head up and down. Seeing that, Seo-san made a happy expression.
And then, she began stimulating my penis with frottage again. I gritted my teeth and endured.
--Then, one hour later...
"U, waaaah! No good! I'm cummiing!!"
Once again, my penis ejaculated accidentally without even lasting ten minutes. Seo-san gave a wry smile.
But it can't be helped! I'm having my genitals in contact with *that* Seo-san! What's more, she's straddling me, moving that intensely, and moaning with such an erotic voice. I've been excited from the very start, it's impossible!
"Seo-san... I really can't cum anymore... sob..."
I pleaded with Seo-san while half-crying. She made a troubled face but soon softened and patted my head. Then, she placed her hand on my cheek and whispered.
"Can't be helped... You tried hard, so I'll let you cum as hard and as pleasurably as you want inside my vagina for the last time ♡"
"!!??"
My penis, which had thought insertion was impossible today with just frottage, instantly entered a state of readiness for battle out of sheer joy.
"Wow... You really are a stud. Well, whatever. Shall we go then?"
Still on top of me, Seo-san placed my semen-covered penis from the frottage against the entrance of her pussy and then lowered her hips.
--Squelch, squiiiiish~~ ♡♡♡

"Ugh, guh...!"
Even though I've experienced this over a hundred times, this moment assaults me with incredible pleasure every time. Seo-san's inside is warm and feels incredibly comfortable.
As Seo-san slowly began moving her hips, I immediately started to lose my ability to hold back.
She started moving slowly at first, but gradually it changed into a rhythmic motion. Each time, a mixture of love juice and semen splattered from where we were joined.
I sensed the signs of ejaculation and relaxed my whole body. However, just before I reached my limit, Seo-san's movements stopped completely.
"Yuuki-kun, you were about to give up and cum just now, weren't you? That's no good, it's training so you have to hold back properly."
"B-but!"
It seems she saw through me trying to cum on my own. It's no use, she's completely grasped my ejaculation timing now.
Seo-san formed a mischievous smile.
"Let's try a little harder, okay? I'll wait just ten more seconds like this for you."
Seo-san said that and began the countdown.
--Ten, nine, eight...
Being left on the absolute verge of my limit is painful. I try to endure somehow, but my body trembles and twitches.
--Seven, six, five, four...
Seo-san's vagina tightened sharply. The head of my penis was kissing her cervix. There was no way the urge to ejaculate would subside in just ten seconds; it only grew stronger.
"Three, two, one... Okay, here I go~~"
"Wait! Seo-san, not yet――――"
Seo-san lowered her hips at the same time as the count reached zero. Simultaneously, she thrust all the way to the deepest part in one go.
"Aaaaah~~~! I-It feels too good!! Don't move!"
"Come on, come on, if you don't hold back properly, starting tomorrow the training will be just frottage and not inside the vagina, okay? Is that alright?"
She can say that because she doesn't know how good her own pussy feels! There's no way I can hold back against this!
Even so, I grit my teeth and try to hold on, but Seo-san speeds up the movement of her hips even more with a mischievous face.
"Ah! No good! I can't take it anymore! Please forgive me, Seo-san!!"
"Hmm, even though you came several times from frottage, you lasted three minutes, so I guess it's okay. I'll let you cum ♡"
Finally, I got permission to ejaculate.
At the same time, I thrust upward madly, aiming for Seo-san's cervix.
Seo-san's eyes rolled back for a moment, but she soon made a happy face.
"Nn♡ It's okay, go ahead and cum...! Yuuki-kun, desperate to cum inside me, is so cute...♡"
Hearing those words, my rationality completely collapsed.
--Splurt! Spluuuuurt! Splurt, splurt!
"Oh♡ It's coming out so much...♡ Here, I'll catch it all for you, so give me more...♡"
Illustration (By Mitemin)
Seo-san tightly squeezed my ejaculating penis with her vagina while grinding her hips against me.
"Ah, ahh, ah... ah..."
I let out a pathetic, girlish voice as I poured a massive amount of semen into Seo-san.
My hips bucked on their own, expelling all the pent-up desire I had accumulated. My mind went blank, and I felt a sensation as if my body was floating weightlessly.
After a while, Seo-san pulled out my penis, a satisfied expression on her face.
As I lay there in a daze, staring at the ceiling, Seo-san gently pulled my head close and pressed my face against her chest. Her soft breasts enveloped my face. Then she began stroking my head.
During sex, she's a bit of a tease, but afterwards, she always spoils me like this. That was truly blissful.
In the end, my premature ejaculation didn't get any better that day either. But we had plenty of time. There was no need to rush; we could take it slow and steady.
Thinking such thoughts, I drifted off into a brief sleep.
