"..."
As Kawasaki lay on his back, silently gazing up at the ceiling, I pressed the tip of my penis against his private parts.
"Was that painful just now?"
He nodded.
"But, can I do it again?"
I nodded. My heart was unsettled.
"I'm going to put it in now, okay?"
After a brief pause, he nodded.
"I'm going to pour everything I have into your womb, okay?"
Without even a moment's pause, I nodded. A shiver ran down my spine.
Thinking that this would be the final performance, I decided to say what I was thinking.
He placed both hands on her cheeks,
"...I'll be gentle."
Watching her eyes widen in surprise, I slowly buried my glans into the folds of flesh that were now fully prepared to receive me.
"Ah, ahh, ohhhhhh..."
Kawasaki's body trembled violently, and each time, the folds of flesh tightened around her.
I was able to put everything in fairly smoothly.
...It feels so good, I think I'm going to come any minute now.
As I enjoyed the sensation of my glans sticking tightly to the very back, she whispered to me, looking at me with teary eyes.
"Why... why are you suddenly being so kind after bullying me all this time...? Now... I can't think about anyone but you...!"
She said, then wrapped her arms around the back of my neck and her long legs around my waist, pressing herself even closer.
...Wow, who is this girl? She's super cute.
"Whoa...!?"
The pleasant tightness of the fleshy folds intensifies, forcing me to instinctively pull my hips back and retreat for a moment.
When I pull my hips back until only the tip of my penis is inside, she looks at me with a longing expression and begs for more.
"Oh... no, give me more..."
He said it, then put force into the leg he was swinging, and pulled me closer.
"Whoa... oh no...!"
"Ah...?"
Because I was caught off guard when he invited me back into the depths of my vagina, I couldn't withstand the intense stimulation and ended up ejaculating part of it.
I managed to stop it once before it all came out, but honestly, at this rate, the rest will probably come out soon too.
...That's so pathetic. I'm going to cry.
Kawasaki looked surprised for a moment, but then a smile quickly spread across his face.
It was the gentlest smile I had ever seen on her face.
"What... did it come out?"
"Well, not everything, but... After all the effort I put in, I ended up showing a really pathetic side of myself..."
He scratches his head vigorously and looks away.
"Hehe... That's fine, whatever. It just means it felt really good inside me, right?... I'm so happy...!"
Saying that, she latched onto my lips and tensed her legs, intensifying the stimulation of her fleshy folds.
Just when I thought things would calm down soon, I was hit with an intense wave of pleasure.
"Mmmmm!?"
I let out a muffled cry as I expelled the rest of my semen.
She widened her eyes in surprise again for a moment, but then quickly narrowed them gently.
Her expression was so incredibly cute and sexy that it caused my hips to spasm an extra time during ejaculation, resulting in a slightly larger load than usual. I'm too embarrassed to tell anyone about it.
Just as I finished and tried to pull away, she wrapped her legs around my waist again.
Stop it! I'm super sensitive right now!
...Well, I was just making fun of Kawasaki all this time, so I'm in no position to criticize anyone else...
Kawasaki smiled, once again standing so close that our noses were almost touching.
"Don't pull out? You've been gentle enough already, so next time, like before...torture me as hard as you can. And make me cum so much that I go crazy? And at the end, cum inside me...into my womb, and make me yours..."
Her voice trembled, and her face was bright red.
I said something incredibly embarrassing.
It's something that makes me feel embarrassed to even give orders.
"...Understood"
He gave a short reply and pulled his hips back significantly.
2.
Without any mercy, he thrusts his hips, which he had pulled back to the very limit, down with full force.
The glans reached the very back of Kawasaki's vagina in an instant.
"Aaaaaaaaaaaaah!?"
Kawasaki let out a scream-like cry and trembled violently.
I had no intention of stopping, and as I pulled back, intending to do the same thing a few more times, she looked at me with tears in her eyes.
"...Ugh...Hmph...I like this...I like it..."
"...!"
A surge of lust welled up deep within me, and at the same time, a calm thought began to sprout about how I could torment her.
The next moment.
He roughly grabbed both of her nipples with such force that it seemed as if he were trying to lift her whole body, and at the same time, with the same range of motion as before, he suddenly increased the speed of his thrusts to full force.
For a moment, she looked confused, not understanding what had happened, but soon she was overwhelmed by intense pain, pleasure, and difficulty breathing, and let out an uninhibited cry.
"Ahhh!? It hurts, no, stop, ahhhhh...~~~! No, stop, I'm coming, I'm coming...~~~!"
I came again and again, my vaginal muscles clenching tightly. But I didn't stop.
"Ah, stop, I'm going to die, I'm going to die, I'm going to die...! Please, stop, please..."
His voice was losing its strength. But he didn't stop.
"I'll listen, I'll do whatever you say..."
The tightness was so intense that I ejaculated with all my might halfway down her vagina. But I didn't stop, continuing to thrust while ejaculating, as if smearing my semen onto her vaginal walls and pouring it into her uterus.
"Ah, it's coming out, it's coming out, why don't you stop it... Ah, ah, ahhhhh..."
How many times did she reach orgasm in just 10 to 15 minutes?
Despite her verbal resistance to the merciless torment, her mouth hung open, drooling, and a faint smile played on her face as tears streamed down her face.
I myself was also becoming highly sensitive, and as I continued thrusting, I was honestly reaching my limits in many ways.
I mustered my strength and put all my energy into it.
"This is the last one, let's go, Kawasaki...!"
"Ah, ah, come, come, come..."
She stared at me with unfocused eyes, and tightened her legs around my waist.
And then, the next moment.
"--------"
My mind went completely blank.
Suddenly, all the strength drained from my body, and I collapsed onto her.
With a gentle smile clearly visible on her relaxed face, she patted my back as if to say, "You did a good job."
...I feel like I was outsmarted right at the very end...
After some time had passed and he had finally calmed down, I looked up and gently placed my hand on Kawasaki's cheek, who was staring blankly with vacant eyes.
"Did you enjoy it?"
He nodded.
"We're going to do this every day from now on, got it?"
I nodded. My heart was unsettled.
"I'm going to do even more extreme things, okay? I'm going to do all the horrible things I can think of, okay?"
After a brief pause, he nodded.
"...I look forward to working with you from now on."
Without even a moment's pause, he smiled faintly and nodded.
3.
Kawasaki, who was breathing softly in her sleep—a far cry from the image I had of her at school—was so cute. I covered her with a blanket and left the room to get her something to drink.
"Hmm?"
When I opened the room door, I felt like I hit something.
Looking down, I saw a cute, familiar creature holding the back of its head.
"Ouch... ah"
It's Komachi. Huh? Why?
However, it was soon clear what they had been doing.
She was wearing just a pair of shorts on the bottom and a T-shirt that I used to wear, which was way too baggy for Komachi.
And when you see him fall over, his right hand is stuck between his thighs.
I realized I was grinning, a creepy smile on my face.
I sat down and asked the question right in front of Komachi's face.
"Komachi... what exactly were you doing?"
Suddenly, Komachi's eyes began to wander.
"Well, well, this is, um..."
Look at the floor.
It's clearly wet.
When I touched it with my finger, it pulled a tiny bit of string.
"Hey, what's this?"
"Oh, um, big brother, this is, well..."
As Komachi begins to panic, a mischievous urge starts to well up inside me.
He lifted Komachi's chin.
"So you were doing it all by yourself?"
"W-w-what!? Th-that can't be..."
Komachi's face turned bright red, and she lowered her head.
Overwhelmed by the excitement and sense of transgression, I swallowed hard and lost all self-control as I reached for the zipper.
"Such a naughty child—"
I was about to say it when...
Komachi looked up, and her face instantly turned pale.
And then, as if he had taken a deep breath—
"N-No, that's not okay!"
"Buggera!?"
I took a sudden palm strike right to the stomach, and I let out a cry like Captain Falcon when he takes damage.
Maybe it's a good thing it wasn't a fist, but... a palm strike causes internal damage, so it resonates through the internal organs...
I got carried away.
I was in agony and collapsed in front of my room.
...The cause was my middle school sister hitting me with the palm of her hand...that's incredibly uncool.
...Either way, I'm going to mess with him mercilessly later. My stomach hurt so much.
After watching Komachi run away crying like something out of a manga, still in agony, several minutes passed, and I finally confirmed that she was recovering, so I slowly stood up.
When I quietly peeked into the room, I could see Kawasaki's sleeping face, as he had just turned over in his sleep and was facing me.
Ah, she's so cute after all.
I love you, Kawasaki!
...Just muttering it to myself made me feel like I was going to die.
The end.
