Chapter 4: Our First Time... (E-book Exclusive Expanded Edition)

Several days passed since that incident...

Senpai's after-school teasing in the library had become a daily routine.

"N-no, Senpai, you can't!"

"Hmm? Why not?"

"Not in a place like this!"

"In a place like this? Are you saying that now?"

"Ugh..."

When she said that, I was a bit at a loss for words. Because, not just that day, but for the past week or so, I hadn't been able to completely refuse Senpai's advances.

"The way you were so earnestly lost in masturbation was cute, you know. It made something in the depths of my stomach clench."

"Ah, that was..."

"Your little penis getting rock hard, moving your hand so intently, letting out those plaintive breaths... fufu, it felt that good, huh? Masturbating while I watched."

"Ah... u-um, y-yes, it felt good, but..."

To be honest, I think it was the most pleasurable moment of my life. I am a guy, after all. I've used various things as okazu, like magazines and movies. But Senpai's breasts, Senpai's hot, wet gaze, Senpai's moist breaths were more sensual than any fantasy I'd ever had, giving me such a strong shock that it overwrote all my previous experiences, stirring up my heart and messing with my head...

"Ah, that was... I-I was just overwhelmed by Senpai's momentum!"

It did feel good. It felt incredibly good.

B-but! It's not like I was happily going along with it. It's more accurate to say that I was completely swept up in Senpai's pace, and before I knew it, I was doing it...

"Fuuun? So, Boy is saying that was my fault?"

"Eh...!? Ah, no, I'm not saying it's all your fault, but..."

"How awful," she said, looking dejected. Seeing her make that face somehow made me feel like I was saying something wrong.

"Um, Senpai...? Um..."

"Yes. But, you're right. It was definitely my fault. So you don't have to worry about anything. After all, I'm the one to blame."

But suddenly, Senpai grinned mischievously, her usual wicked smile.

Th-this is Senpai's trap!

"Ah, w-wait, Senpai... ngh... really, no...!"

See! Just as I thought! When will I ever learn, me! Look at Senpai's unbearably cute, devilish smile! No! Wait! That's not what I should be thinking about right now...!

"D-don't take off my pants! And, and briefs are even worse!"

"It's okay, it's okay. Even if someone saw us, we could come up with an excuse."

"N-no, I don't think so!!"

It's true that not many people come to the library at this time, but that doesn't mean no one ever comes. Besides, even if we're hiding behind the bookshelves, if someone just peeks in, everything will be out in the open. There's no way I can be so carefree about it.

"No one has come so far, so it'll be alright."

"Isn't that a little too optimistic!?"

"Fufu, hello. You seem energetic today."

"Wh-who are you talking to!?"

"Hmm? Boy's little penis, of course?"

"Please don't say 'little penis'!"

Hearing the words "little penis" from Senpai's mouth, I felt embarrassed, awkward, and somehow strangely uncomfortable and itchy. Especially since she was now staring intently at that embarrassing part, I really wanted to scream and rage.

But, if I made a loud noise, the chances of someone finding us would only increase, but even while worrying about that, for some reason, my foolish thing was getting bigger and bigger...

"If not 'little penis,' then what should I call it? Male organ? Penis? Phallus? Hmm, other options are 'erection,' 'meat rod,' 'one-item,' 'mara'..."

"That's not what I'm talking about!"

"Fufu, but it seems like this little guy is saying hello to me, you know?"

"I-it's just a poorly behaved child..."

Seeing the evidence of my arousal getting bigger and harder, there was no room for me to make excuses.

"You say no with your mouth, but this part is honest, isn't it?"

"P-please don't say things like a corrupt official!"

"Fufufu, isn't it good, isn't it good?"

"Th-that's why, no... ngh...! ...Uaah!"

When Senpai's supple fingers touched me, pleasure ran through my spine in waves.

"It twitched," she noted.

"Y-yes, really... no... ungh... uah...!"

When she gently squeezed it, a strange sound escaped my lips.

"You know, I just want Boy to feel good."

"I-it's not like I hate feeling good, but...!"

"Then, isn't everything solved?"

"Th-that's why...! That's not it...! Not in... a place... like... ngh...! ...This! Aaaah!"

When she stroked me gently, my voice pathetically jumped up an octave.

"Fufu... the way you're holding back your voice, it's thrilling."

"Sen...pai...! Are you... ngh... enjoying... this!?"

"I won't deny it."

No good...! No good! This kind of thing! It's absolutely wrong, but...!!

"Today, I've prepared a new technique. I don't know if I'll be able to do it well, though..."

Eh!? A new technique...?

Oh! Wait, I just got my hopes up for a second there! Idiot! Me, you idiot!!

"It's something I read about in a book called 'boob job'."

"N-no! Noooooo! Nooooooooo!!"

A scream suppressed to a whisper. But I couldn't escape.

Even if Senpai, being a girl, was holding me down, if I was serious, I should be able to shake her off...

"Wow... being挟む (hasamu - pinched/held between) between breasts feels different from the heat I feel on my fingertips."

"Augh... ngh... Se... Senpai... ngh...!"

Senpai's... breasts!!!

Whoa... what is this... amazing...! Soft and fluffy...! Smooth...! Warm...!

I couldn't resist. There's no way I could resist.

This feeling of pleasure and bliss, there's no way I could willingly let go of it.

"Let's see, it seems like it's good to drool and add moisture... like this... maybe...?"

"U-ugh...! Ah! N-no! No, please! If you... squish squish... like that...!"

"Fufu... now, like this, I'll squish and squish my breasts from both sides..."

"Ugh...! Ah... ngh!"

"So good you can't even make a sound?"

"N-no... ngh... augh... ngh! No... please... Senpai... aah... ngh!"

"Boy's reactions are so innocent and cute. Seeing you like this, my service spirit as your Senpai is stimulated, you know."

"W-wait...! Senpai...! What are you...!?"

"It seems that 'boob job' is even more effective when combined with tongue licking."

Chuckling, she stuck out her bright red tongue.

That small, moist lump of flesh, licked the corner of her lip and slowly approached my penis...

Th-this is definitely going to feel good...! I'm gonna get swept away! N-no, I mustn't—!

Just as I braced myself, determined...

BOOOOOOOOOOOOOOOOOOM!!

Suddenly, a loud sound, like fireworks going off, echoed.

"Whoa!"

"Hmm...? What was that...?"

"What could it be..."

I couldn't help but raise my voice and look back.

And there, I saw a sky covered in thick, heavy-looking clouds.

"Wow, the sky's completely black."

Just a moment ago, the weather was so nice...

"Was that... thunder... just now?"

"Yeah. It was pretty close."

Listening to the rumbling thunder, like a cat purring in its throat, we looked at each other. Just a few seconds ago, we were about to do something lewd, but our enthusiasm was completely dampened.

"Looks like it's going to rain."

"That's a problem."

"Boy, do you have an umbrella?"

"No... I don't."

The morning weather forecast said it would be sunny all day today, so I didn't even bring a folding umbrella.

"I see, that's tough."

Senpai must be in the same situation. Looking up at the dark rain clouds, she sighed softly.

"Hmm... running might be okay... maybe?"

"Huh?"

But the next moment, Senpai chuckled.

"Alright, if that's decided, let's hurry! A race against the rain clouds!"

"Eh? Eh? Ehhhh!?"

"Come on, come on! Hurry, hurry!"

"W-wait! W-wait! This...! Let me put this away first!!"

I was being patted on the shoulder and urged to hurry, but first I had to put my half-erect penis, which was still sticking out, back into my pants, or it would be a disaster.

"Oh, right, that's true. Sorry to interrupt you midway, but I'll make sure to continue it properly later, okay?"

"N-no, that's quite alright!"

My little guy twitched in response to the words "continue it later," but I pretended not to notice...

I put away what needed to be put away, and then rushed out of the library with Senpai.

About halfway home. We reached the crossroads where Senpai and I always said goodbye, and just as I said, "It looks like we'll make it home without any rain," as if waiting for those words, large raindrops started pouring down from the sky.

"Ahahaha♪ You sure set up a perfect flag there, Boy."

"I'm sorry..."

"Just kidding. It's not your fault."

I thought it was just going to be a drizzle, but then dobaah! It was pouring harder than a shower. Raindrops, as intense and painful as a waterfall, instantly soaked our hair, our uniform shirts, our pants.

"Wow, this is intense. Is this what they call a guerrilla rainstorm?"

"Yes, probably..."

"It's a bit too intense to be called an evening shower. But, thinking that summer is approaching, it makes me feel a little better... fufu, or maybe not?"

"Maybe just a little bit, I guess."

"Haha, just a little bit. Yeah, just a little bit."

We took shelter under the eaves of a nearby convenience store, watched the rain pouring down like buckets being overturned, and exchanged words with wry smiles, feeling a bit relieved.

"Hmm, this is really heavy rain. Even with an umbrella, it wouldn't have helped."

"Yeah..."

Senpai sighed, sounding a little frustrated, but for some reason, she also looked a little happy.

She looked up at the sky with gentle eyes, wiping raindrops dripping from her hair with the back of her hand. That gesture, though casual, looked very refined, and I thought, in a cliché way, "She's beautiful."

"..."

You could say it was picturesque, Senpai really looked beautiful like this.

They say "a handsome man dripping wet," but Senpai was "a beautiful girl dripping raindrops," and her moist forehead visible when she brushed back her bangs, her pure white cheeks with droplets falling potari, potari, her slender neck with water trickling down thuuu, everything... everything was beautiful, wonderful, making my heart race...

"Hmm? Is something wrong?"

"N-nothing!"

Noticing my gaze, I hurriedly looked away.

"Is there something on my face?"

"N-no, there's... nothing on your face, yes!"

"Hmm. I'm curious, I wish you would just tell me what you're thinking."

"Really... it's nothing... ngh...!"

There's no way I could say, "I was just captivated by Senpai's face." It's embarrassing, and I'd definitely get teased.

Besides, um, just now... that... it... ended halfway through, so... to put it bluntly, I was still horny...

Uwaaaaaah! I'm the worst!

To be horny even at a time like this, am I a little too obsessed with eroticism?

"Boy. There are no secrets between us, remember?"

"Y-yes."

"If you understand, could you at least look at me?"

Her words sounded strangely lonely. What kind of expression was Senpai making right now?

Feeling a pang of guilt, thinking that wasn't right, I slowly turned to face Senpai...

"---------------!!"

The next moment, I realized something incredible and averted my gaze again at the speed of light.

N-n-n-n-no way...

"Hmm? What's really wrong? Are you feeling unwell?"

"N-n-no, no, no, no! It's nothing, it's nothing at all!!"

I shook my head like a wet dog, buruburubururururu.

"No, but, you really do seem strange."

"I-I'm always strange, that's just how I am!"

"I see. Indeed."

Sh-she actually said "indeed"! I said it myself, but it still stings a little.

Wait! That's not what matters right now!!

"U-um, Senpai, a towel... a towel..."

I rummaged through my bag and pulled out a towel.

"H-here, it's unused! It's clean!"

"A towel...? You mean to wipe off the rain?"

"Y-yes, yes, yes! That's right!!"

"Hmm..."

Senpai took the towel from my hand, looking thoughtful.

Well, I didn't actually see if Senpai took it, since I wasn't looking, but it's just me and Senpai here, so...

"Ah..."

And then, at that moment, Senpai let out a small breath, as if noticing something.

"Fuuun... I see..."

And then, the next thing Senpai breathed out, in that breathy voice of hers... a chill ran through me, zokuzoku zoku, from my toes to the top of my head.

"...Boy."

"Y-yes! What is it!?"

"Thank you for being considerate. It's alright now. So, could you look at me?"

"Eh... ah... um..."

Alright... alright? Really?

"I want to properly say thank you, looking you in the eye."

"Y-yes, you're right..."

Trusting Senpai's gentle voice, her cheerful voice with a soft chuckle, I slowly shifted my gaze... No, it's not alright!!

"You saw it," she stated.

"------!!"

"You thought you shouldn't look at my see-through underwear, didn't you? Boy is such a gentleman."

Darn it! I've been tricked!!

"Oops, no you don't."

When I tried to avert my eyes again, my arm was firmly grabbed.

"If you go over there, you'll get wet again."

"N-no, wa-wa-wa-wait, wa-wa-wait, no... no, please, Senpai!!"

"What is it?"

"It's, um, th-th-th-that..."

It's too much for my eyes to handle!!

"Fufun."

Seeing me flustered and panicked like this, Senpai grinned wickedly. Then, gently, she extended her free left hand to her chest... to her soaking wet, dripping necktie...

"Would it be easier to see like this?"

She slowly pinched and lifted it up.

"----------!!"

"See-through wet clothes are exciting, aren't they? I know. I kind of like it too, I think it's quite a fetish point."

"Se-Senpai... um... that..."

"Oh dear, even my bra is completely visible. I wonder if I should have worn a cuter one. What do you think, Boy?"

"Awawa..."

I could no longer avert my eyes, but I also couldn't stare intently. My head was spinning, I was completely confused, and yet, my lust was only growing stronger, awa, awawawa, awawawawa...

"Senpai looks cute no matter what kind of underwear she wears!"

And, the words I squeezed out were those.

"...Huh?"

At my words, even Senpai's eyes widened for a moment, and she froze.

"F-fufu... heh-heh... ahahaha... ahahahahahaha!!"

And then, she clutched her stomach and burst out laughing.

"Y-you... you really do like me, don't you... haha... ahaha... ngh..."

That was true, but being told it so directly made my face hot.

"Ahahaha! I didn't expect you to say that, ahahahaha!"

"Ugh..."

Embarrassing. So embarrassing my face felt like it was on fire.

Ah, so this is what it means to want to disappear from the face of the earth... What am I saying, all flustered like that...?

"Fufu... ahahaha..."

I think Senpai is laughing too much!

"Haaaa, my stomach hurts. I laughed too much. Fufu, ahaha, tears are coming out."

Wiping her eyes, Senpai was still chuckling. With every shake of her body, droplets of water danced from her hair, sparkling.

"Haaa... sorry, sorry."

And then Senpai placed her hand on her chest and took a deep breath, fuuu.

"I'm happy. Thank you."

She gave me a smile so gentle and cute that it made my heart clench.

"But in that case, you should have worn something cuter. That's the bare minimum of etiquette, you know."

"What kind of etiquette is that..."

"Just curious, but between frilly pastel-colored ones and slightly risqué black ones, which do you prefer?"

"That would be, um... pastel colors..."

Senpai is beautiful and mature, so black would surely suit her, but personally, I prefer a cuter style...

"Hoooon. I see, I see. That's interesting... fufu."

"------!"

N-no good! I had a bad妄想 (mousou - fantasy/daydream) for a moment there!

If I keep having these fantasies, then again, the restlessness in my chest will... !

"What are you making me say!"

I frantically crumpled up the妄想 in my head and tossed it away, shaking my head vigorously. A little bit of pastel color still lingers in my mind, but I'll just pretend I didn't see it, pretend I don't know.

"I was just asking a question."

Senpai chuckled, amused by my reaction. It wasn't her usual wicked smile, but a somehow very cheerful, and for Senpai, a slightly childlike and cute smile.

"The rain has stopped," Senpai said, suddenly looking up at the sky.

"It really was a guerrilla rainstorm," I replied.

"Even weather forecasters would have trouble predicting this, wouldn't they?"

I followed Senpai's gaze and looked up at the sky too.

Spreading across our sky was the blue sky after the rain. Sunlight so bright it almost hurt my eyes.

"Summer's almost here," she said.

"Yes," I replied.

"Something to look forward to," she added.

But, was it just my imagination, or did her voice sound a little lonely?

"Um... Senpai..."

Feeling a vague sense of unease, I was about to ask, but...

"Even so, we're soaked to the bone, like drowned rats. If we stay like this, we'll catch a cold, so you should take a shower at my place."

"Whe...?"

Shower at my place...?

Does that mean, shower at Senpai's house...?

Um, so? Meaning? ...? ... ... ... !?

"EEEEEEEEEEEEEEEEEEHHHHH!?!?!?"

At the sudden and outrageous development, I gave a delayed reaction like an old-fashioned computer, and at the same time, all the little questions in my head were blown away.

"Here we are," Senpai said, guiding me to her house. It was a perfectly ordinary detached house in a perfectly ordinary residential area.

In the parking space was a kei car.

Pastel-colored and somehow cute, a small car with round headlights that gave it a puppy-like charm. I think I'd seen it on TV before, introduced as "hugely popular with women!" I'd somehow imagined Senpai's house would have an expensive foreign car, so the gap made me happy.

Also, in the small but neatly kept garden, brightly colored flowers were blooming. It was a proper home garden that had been carefully tended, and you could feel the dedication in every detail. My mom also wants to create a home garden, and I bet if she saw this garden, her desire to do it would skyrocket, but Mom is easily bored, so before I know it, it'll be my responsibility... I can easily imagine that future... Well, it's not like I'd mind. I don't dislike that kind of thing either.

Anyway, in that way, Senpai's house was probably just like any other, a 'normal' house where the people living there put their love and care into it.

But, to me, this house was special. Senpai lived here, Senpai woke up and went to sleep here, ate meals here, studied and read books here, and also, um, took baths here... a very special house.

Maybe this way of thinking is heavy and creepy, though.

"Don't hesitate, come in. No one should be home today," Senpai said.

"Y-yes... yes?"

Did she just casually say something amazing just now...?

N-no, there's no weird meaning to it, right? Yeah, definitely.

"Excuse me for intruding..." I said hesitantly, stepping through the gate and following Senpai into the entrance.

"Iroha-chan?"

Then, unexpectedly, a voice came from inside the house, Senpai looked surprised, and I almost jumped like a cat startled by a barking dog.

"Fumika-san. Weren't you supposed to be out today?"

"Fufu, I was, but you see, I'm a bit of a scatterbrain and forgot my wallet. But, thanks to that, I might have avoided getting caught in the downpour."

Saying that, someone came jogging down the hallway, pata pata.

"Oh my, you're soaking wet, Iroha-chan."

Senpai's older sister, maybe? A young woman who looked to be in her mid-twenties. More cute than beautiful, with a gentle, soft aura.

"We got caught in a real downpour," Senpai explained.

"Oh dear. You need to take a shower quickly... oh? And who's this?"

The woman—Senpai called her "Fumika-san"—suddenly noticed my presence and tilted her head slightly.

"Ah! Um! That's...!" I stammered, flustered.

"Let me introduce you, Fumika-san. This is Isawa Makoto-kun. He's my junior," Senpai said, covering for my completely suspicious reaction with a chuckle.

"Oh, you're him. Fufu, I've heard about you from Iroha-chan," Fumika-san said.

"A-ah, um, h-hello, I'm Isawa! I'm always indebted to Senpai!!" I bowed awkwardly.

Heard about me? What exactly has she heard...? I'm really curious, but... and, suddenly meeting Senpai's older sister is a bit, quite a lot, like, I'm not mentally prepared for it...

"Hello. I'm Hamasaki Fumika," she introduced herself.

"This is my mother, Boy," Senpai added.

"Huh!? M-Mother!?!?!?"

No good! It's not just about mental preparation anymore! An older sister would already be nerve-wracking, but her mother!? Is, is this okay, in these soaking wet and miserable clothes!? Sh-should I have brought sweets or a gift? Will she think I'm rude and ill-mannered!?

"As you can see, Isawa-kun is also in a puppy-dog state, all drenched, so I brought him here to take a shower," Senpai explained, ignoring my internal turmoil.

"I see, is that so," Fumika-san responded.

She smiled at my face, which I guess means I passed the first impression check, at least?

But, wait... Mother? She's young... incredibly young...

My mom also looks young for her age, but Fumika-san is even younger... or rather, it's hard to believe she's a mother at all...

"Fumika-san is beautiful, isn't she? She's my pride and joy, my mother," Senpai boasted.

"Oh, stop it, Iroha-chan, what are you saying," Fumika-san blushed.

"What do you mean 'what am I saying?' It's the truth," Senpai insisted.

Watching them playfully interact, they looked more like close sisters than mother and daughter.

"Isawa-kun," Fumika-san turned to me.

"H-yes!!" I snapped to attention.

"I'm heading out now, but please, take your time warming up in the shower and relax," she said kindly.

"Ah! Thank you very much!!" I replied.

But, really, is it okay, Mom? Isn't this a bit too much trust in someone like me...?

"Alright then, Iroha-chan, I'll leave it to you. Be careful to lock up," Fumika-san instructed Senpai.

"You be careful too, Fumika-san. Do you have everything this time?" Senpai asked.

"Fufu, yes, I'm good. Well then, I'm off," Fumika-san said.

"Take care," Senpai replied.

"Ah, um... take care," I added.

"Thank you, Isawa-kun. I'm leaving now," Fumika-san smiled at me before heading out.

Is this really okay...?

I wonder if her father will come home later and say, "How dare you lay a hand on my daughter! Prepare to atone with your life!" or something like that...

Kappon.

That sound effect is often used in anime and movies for when someone gets into the bath, but what is that sound actually supposed to be?

That thought, something Senpai might suddenly bring up, randomly popped into my head, and I vigorously poured hot water over my head.

"Is this really okay..." I muttered.

And here I am now, being allowed to take a bath in Senpai's house. Even going in before the owner, Senpai. Senpai had offered to go first, but I had insisted and won out.

Or rather, it was more like—

"No, that's not right, for me to take a bath in Senpai's house before Senpai. The owner should go first."

"The owner isn't me, it's my father. Besides, if my father found out I was leisurely using the bath before a guest, I'd be the one getting scolded."

"But still..."

"You're so stubborn, aren't you? Hmm? Or, wait..." Senpai paused, a teasing tone entering her voice.

"Wh-what is it?" I asked, feeling a little uneasy.

"Hoooon, could it be, Boy, you're planning to savor my bathwater leftovers... Even I would be turned off by someone as maniacal as you with that kind of fetish."

"Thank you, I will accept your kind offer without any further hesitation." I replied quickly, wanting to dispel any such notions.

--- Well, something like that happened.

Even I couldn't stand being labeled as a pervert with such extreme and twisted fetishes.

"Uuuum, even so..." I murmured, having finished showering and taking a breath, looking around.

A spacious bathtub, a washing area about twice the size of our bathroom. A monitor for the bathroom was embedded in the wall, and background music that sounded like birds chirping was playing from somewhere...

Apparently, it was a 24-hour bath that Senpai's father, who loves baths, was proud of. It also had a jacuzzi to soothe shoulders and lower back, adjustable lighting, and a waterfall shower from the ceiling, in short, a high-tech bath with many functions.

"Is it really okay for me to use this while her father is away..." I worried.

I hope I don't get unceremoniously executed...

In my head, Senpai's father had completely become an image of a stern lord.

"It was supposed to be just a shower, though..." I thought to myself.

But Senpai had kindly offered, and said she'd even put my wet uniform in the dryer, so I thought it would be rude to refuse her kindness, but—

"Thinking about it, we have a 24-hour bath at home, so don't just take a shower, go ahead and take a bath."

"Eh, no, that would be, really..." I hesitated.

"In the first place, this 24-hour bath is completely my father's hobby. Even he doesn't use it every day. It would be better for the bath to be put to good use by Boy here, the bath would be more rewarded, you know."

"Is, is that really how it is...?"

--- Skillfully talked into it, I ended up (somehow?) accepting the bath. I'm just...

"Too easily swayed, aren't I..." I sighed to myself.

It's not like I'm saying something old-fashioned like "men should take the lead with girls," but I feel like if I don't have a little more, how should I put it, agency, I'll be a failure as a human being.

"Okay, yeah, let's get out of the bath and take my leave. I shouldn't act like a sneaky thief," I decided.

Muttering something that Senpai would probably scoff at with "You're so old-fashioned," I stood up with a determined mun... and just then—

"Boy. I'm leaving a bath towel and change of clothes here," Senpai's voice called out suddenly from the changing room.

"Hah! Yeeees!!" I yelped, instinctively covering myself and crouching down in a panic.

"I'm sorry it's just my father's old clothes, but could you bear with it until your uniform is dry?"

"Y-yes, it's fine! I-I'm terribly sorry to your father...!" I stammered.

"Boy is so old-fashioned," Senpai chuckled, her voice sounding muffled from the other side of the thin door. My embarrassment grew even more.

Just a single thin door separating me from Senpai, naked in front of her, was a situation that felt incredibly embarrassing and incredibly abnormal to me.

"How's the bath? If it's too hot or too cold, don't hesitate to tell me," Senpai called out.

"Ah, n-no, I haven't used the bath yet, just the shower..." I replied.

"You haven't gotten in the tub yet?" Senpai asked, surprised.

"Um... I just felt a little hesitant..." I admitted.

"Uuuum, you're really reserved, or maybe cautious..." Senpai mused.

"I-I'm sorry," I mumbled.

"No, it's not something to apologize for. No, it's not something to apologize for, but... if it's come to this... there's no helping it," Senpai declared.

"Eh...? What did you just say?" I asked, confused.

Senpai said something with a slightly exasperated tone, but I didn't quite catch the last part, so I asked her to repeat it, but Senpai didn't reply. Instead, I heard—

A sound like something rubbing together.

Shuru, shuru, this sound, I feel like I've heard it somewhere before...

"It seems like for someone as stubborn as you, I have no choice but to forcibly throw you into the bath."

"Eh? Eh?" I stammered, completely lost.

And then, suddenly, abruptly, with a gachari sound, the bathroom door opened, and Senpai stepped in.

Naked.

Nude.

Stark naked.

In her birthday suit.

And, um, um, what else...

Wait, this is not the time to be thinking about that!!!

"GYAAAAAAAAAAAAAAAH!!" I couldn't help but let out a high-pitched scream.

"'Gyaaa,' how rude. Normally, when you see your girlfriend naked, you'd make a more sensual sound, wouldn't you?" Senpai teased.

"N-no, but, um, uh, awawa..." I stammered, completely flustered.

Awawawawa... awawawawawawa... I was completely unprepared for this situation, awawawawawawawa... !

"Well, whatever. Here, turn your back to me," Senpai instructed.

"Ueeh!? Ah, um... hyaaugh!" I yelped in surprise.

"Look at your body. It's still so cold. You'll really catch a cold, you know?" Senpai said with concern.

"Eh, ah, th-that's, th-th-that's true..." I stuttered, still overwhelmed.

"You're such a handful, junior-kun. Just stay still for a moment," Senpai said, ignoring my confusion and settling down behind me, picking up the shower head.

"Uhyah!" I squeaked again.

"Even if it's just a shower, you need to shower properly, you know," Senpai scolded gently.

"Ah, augh... augh augh..." I mumbled, completely overwhelmed.

"You're really a troublesome kid," Senpai whispered in a gentle, warm voice, showering me with warm water and stroking me gently like giving a puppy a massage.

Shoulders... nape of my neck... back... waist. And head...

Senpai's touch, like giving a dog a shower and ruffling its fur, was ticklish, but also very pleasant, and I forgot my embarrassment, lost in the physical contact.

"Hmm, you've warmed up a little now," Senpai noted.

"Ah, thank you very much, Senpai," I replied, feeling a little calmer.

"If you were to catch a cold, I'd be tormented by guilt, you know," Senpai said.

"N-no, that's what I would feel too! That's why I wanted Senpai to go in first..." I protested weakly.

"Fufu... Boy is really kind, isn't he. But, it's okay. There's a good way to fulfill both my wishes and your feelings," Senpai said with a chuckle.

"A good way, you say... uhyah!" I yelped again.

S-se-Senpai! Senpai!! M-my breasts! My breasts are funya against my back...!!!

"Hmm? What's wrong, Boy?" Senpai asked, noticing my reaction.

"B-breasts, y-you know, b-breasts! Your breasts! Touching my back...!" I stammered, completely flustered.

"Fufu, does it feel good?" Senpai teased.

"G-g-good, it's not that it doesn't feel good, but, um, that's..." I tried to explain, still stammering.

"Hmm? Is this not enough, then..." Senpai mused, as if considering.

Wa-wait a minute, Senpai! Senpai is probably misunderstanding something...!

"In that case, you do this, lathering plenty of body soap all over your body..." Senpai continued, now applying soap to both of us.

"Unyooooooough!" I groaned involuntarily as the slippery soap was applied.

Nyurun! It's getting slippery! Nyurun!

Th-this sensation, could it be...?

"Ah, that groan was a 'it feels good' sound, wasn't it? Isn't it, Boy?" Senpai asked knowingly.

"Ugh, uhih! Uhyah! It, it feels g-good, it does, but...!" I admitted, though still flustered.

Body soap applied to Senpai's smooth skin. It turned into a slippery, bubbly lather, reducing the friction between me and Senpai.

Every time Senpai twisted and turned her body, nyurun, funyu, tsurutsuruun, sensations, pleasure I'd never experienced before, were transmitted to me.

"Fufu, this is getting fun, isn't it," Senpai said, sounding genuinely amused.

"N-no, please stop, Senpai...!" I protested weakly.

"Eeeh? Really? Your body doesn't seem to be saying that, though?" Senpai teased again.

"Wh-what do you mean..." I stammered.

"Specifically, your cute yet virile little penis is..." Senpai hinted, her voice suddenly shy.

"Eh!?" I exclaimed, and without thinking, I looked down. And there, what I saw was...!

Whoa! Whoaaaaaaaah!

My foolish thing, completely enlarged, pointing skyward, stiff and erect!

Th-this guy, always, always, never listens to me...!

"Hmm... as expected, Yotsuya-kun and Gotou-kun's wisdom is helpful. 'If you press your breasts against a boy's thing and rub it around, they're totally hooked, seriously,' they said. The words of experienced people are very insightful..." Senpai murmured, quoting her friends.

"N-no! Uhyah! No! No, please, Senpai!!!" I protested again, completely overwhelmed.

"They said most innocent boys say that kind of thing. They also said it's cute..." Senpai added, quoting them further.

Pre-assure on my back! Amazing pressure!! An unbelievably soft and comfortable object, passing over me with only a slight resistance – this pleasure.

A-and, and, something kori... kori, could this be, co-co-co-could this be it! This! Could it be Senpai's... TKB!!????

"Looks like your back alone isn't enough to satisfy you anymore," Senpai observed.

"Ueeh... n-no, that's not... uhyah!" I exclaimed, flustered.

"No use denying it. Your 'here' is too honest, it sees right through your heart," Senpai teased.

"Ah... ugh... ngh...!"

Senpai reached around from behind and grasped my stiff penis. It was held quite firmly, but I felt no pain, only pleasure washed over me.

"N-no... Senpai... really... augh... ngh! No... please..." I pleaded weakly.

Her hand, generously covered in body soap, moved up and down, slippery and smooth.

Squeezing and releasing, varying the pressure and rhythm, Senpai was playing with my thing.

"It's getting harder again," she noted.

"Ah! Ugh... ngh! N-no! Really... no... no...!!" I protested, my voice strained.

She enveloped my shaft with both hands, stroking it nyuru, nyuru.

"Augh! Slippery... ngh... no!"

Then, she slid both hands down to the base, wrapping them around my glans and stroking it in short, quick motions.

"You really moan so pleasurably, you know. I think that's very cute about you," Senpai said, her voice soft and teasing.

"Ngh! Kah! Th-that kind of thing, even if you say that..." I stammered, unsure how to respond.

It's not that I'm not happy... I think, but if Senpai is happy, that alone makes me happy.

Besides, how should I put it, um, well, in other words, this pleasure isn't something I exactly dislike...

"Fufu, your whole body is twitching. Cute. Could it be, customer, is this your first time at a place like this?" Senpai said, playfully adopting a different tone.

"Wh-where did you learn lines like that!!" I exclaimed, surprised and embarrassed.

"Hmm? From Yotsuya-kun and Gotou-kun, of course?" Senpai replied innocently.

Y-YOTSUYA AND GOTOUUUUUUUU!! What are you teaching Senpai!!

"Should I not have said that?" Senpai asked, tilting her head slightly.

"Y-yes, I think it's better if you don't say it... augh... ! At least, not to anyone but me...!" I managed to squeak out, completely flustered and overwhelmed.

"Hehe, who else would I say it to but you? I only do these kinds of things for you. Yotsuya-kun and Gotou-kun even told me, ‘Icchan might be single-minded and reliable, but don't make your junior worry, okay?’ I swear, my heart belongs only to you."

"Senpai… Ah…! Augh…!"

…If you say such wonderful things… my body… my head… it’s tingling all over…!

"Ah… It’s gotten bigger again… amazing, it’s even bigger than before."

"O-Of course, if you do things like this… a-and… augh…!"

"And?"

"Because the last time was half-hearted, I was, you know, feeling restless…"

"Hmph."

Ah. Maybe I chose the wrong words.

"Is that so, is that so? You wanted me to touch you that much?"

B-But, but, that’s definitely the truth, and I can’t deny it, and actually right now, being touched like this feels so good and pleasurable…

"Y-Yes! That’s right!"

Half in desperation, half in a rebellious tone, I said.

"I-Is that so… I see…"

My Senpai seemed taken aback for a moment by my stronger-than-usual tone, and then she murmured as if deeply moved.

"Then… this time, I really have to make sure to finish properly, don’t I?"

"Ah…! Ngh! Senpai…! Ah! Senpai…! Th-There…! It feels too good…!"

"Heehee… You’re feeling it. You’re feeling it, aren't you, shounen? Your back is twitching."

"Se… Ah! Senpai…! I… I… I’m going to…!"

"You’re going to come…? You’re going to cum…? It’s okay… it’s okay… come as much as you want… come as much as you want…"

"D-Don’t…! St-Stop…! N-No… stop it!"

Shivers. My back is trembling.

Being pressed against her breasts, being gently caressed… I… I…!

"You can let out everything, everything that you couldn’t release because you were unsatisfied earlier."

Her hot, feverish voice whispered in my ear.

Surely, right now, Senpai’s cheeks are flushed red, her eyes are glistening with tears, and she’s trying to make me feel good. Thinking that, I, I can’t hold back anymore… or rather! There’s no need to hold back, is there?!

"Ah! Ungh! I’m…! I’m going to cum!! I’m going to cuuuummmmmm!!"

"Ah…! Ungh…! Ah…! Augh…! Ungh…!"

"Amazing… so much… and… it feels thicker than usual…"

"Hah… ungh… u, uuu… aaaaaa…"

Senpai’s voice, wet, hot, and slightly hoarse, leaked out in fascination at my ejaculation like a broken fountain.

"I thought… my back would break…"

Or rather, it felt like it was half-broken.

Before I knew it, I had slipped off the stool in the wash area, and I couldn't even stand up. I could only pant roughly.

Ah… No good… It feels too good… I don’t feel like doing anything. Is this what they call… ken…

"Is this what they call, sage mode?"

"……"

"Oh? Was I wrong?"

"No… you’re right… but really, Senpai… you know so many strange things. And that too…"

"Yeah, Yotsuya…"

"No, it’s fine. I can pretty much guess."

Maybe Senpai should reconsider her friendships.

"To defend them a little, shounen, Yotsuya-kun and Gotou-kun are worried about us and cheering us on, you know? They are kind and good kids."

"……It’s okay. I understand."

No, no, people who are friends with such a kind Senpai can’t be anything but kind and good people.

But…

"They were raving about how shounen would absolutely love body soap bubble play, and they were right. I’ll make sure to prepare a mat next time. Should we prepare lotion? Or something?"

"No, um…"

Even if you say that with the biggest smile…

Yeah, maybe I should have a serious ‘talk’ with Senpai’s friends once. Though, I have a feeling I’d get completely defeated…

◇　◇　◇

Splash

"……!"

I snapped back to reality, feeling like I heard that ‘bath sound’ again.

"I was spacing out…"

Senpai, after pushing me into a state of blissful exhaustion, said something like an older sister, ‘Make sure to warm up properly before getting out,’ with a very satisfied smile, and left the bathroom.

Following her words, I was obediently soaking in the hot water…

"Am I relaxing too much…?"

I suddenly worried about my own behavior.

Even if she said ‘take your time,’ isn’t it presumptuous of me to actually relax and unwind this much…?

My long sage mode finally passed, and my body was thoroughly warmed and relaxed, and it was only then that I realized such a thing.

Whoosh! I vigorously got out of the bath and hurried outside…

"……Before that, I need to rinse off the bath…"

If any residue from earlier, or evidence of what happened, remained, that would be bad, and it also feels wrong to impose on someone else’s bath and leave it dirty. So, I quickly rinsed the wash area with the shower, checked with a point and call, and then moved to the changing room.

There, the dryer was humming loudly. Inside the drum, my uniform and underwear, and…

"Senpai’s… uniform…"

In the drum that seemed a little large for a regular household, my shirt and Senpai’s shirt were tumbling and intertwining as if embracing each other.

"……gulp"

Hey! Not ‘gulp’!

W-Why am I getting turned on looking at the laundry in the dryer…?

Hastily, I grabbed the bath towel Senpai had left for me.

I pressed the fluffy texture against my face with a baff, roughly ruffling my face and hair.

Ah… it smells nice…

"No, that’s not it!!"

No good. The switch in my head is somehow going in a strange direction.

Even after releasing so much, I’m still completely in ero-mode, and even in high-boost mode with the limiter removed. This is bad. This is really bad.

"F-First, let’s get dressed."

Underwear, and then a sweatsuit set. I think she said it was her dad’s, but sadly, it’s oversized for me. N-No, no, I’m still going to grow taller!

Still, thinking that these are Senpai’s dad’s clothes, the ero-ero mode in my head calmed down a little. I definitely felt Senpai’s dad, whom I’ve never even met, smiling and silently applying pressure, and I felt a sense of tightening up.

‘I’ll be in my room, so come when you’re warmed up. It’s the room furthest in on the second floor,’ Senpai had said when I was getting out of the bath.

"Senpai’s room…"

Various thoughts floated into my head, and I gulped.

Especially what came to mind was –– Senpai’s selfies, which are carefully stored in my secret folder on my phone –– and often comfort me.

The room where those photos were taken…

Senpai’s private room. The room where Senpai is the most defenseless in the world…

"Aaaaaah! Enough! Mooou!"

Again, I shook my head violently, trying to chase away the lewd thoughts that were starting to surface. I shook so hard I heard a crack, but that’s a noble sacrifice.

"I have to go to Senpai’s room, anyway…"

I can’t keep Senpai waiting forever. So, I steeled myself…

"Alright!"

I left the changing room.

I was a little dizzy and my steps were unsteady, though.

◇　◇　◇

Thump, thump, thump

As I slowly walked up the stairs, my footsteps echoed more than I expected.

When I tried to quiet them, they just got even louder – a vicious cycle.

But, when I thought about it, there was no need to be quiet, so I decided not to worry about the footsteps.

Thump, thump, thump

Still echoing…

Well, I mean, it’s impossible not to care, but I’ll try to not care as much as possible.

"……"

While thinking about such things, I had arrived in front of Senpai’s room – probably.

The room furthest in… this must be it, right…?

I took a deep breath and knocked on the door.

Knock knock, a dry sound, and the air vibrated.

"Is that shounen?"

Senpai’s voice came back in a fraction of a second.

"H-Yes! It’s Isawa! Excuse me!"

"Hehe, it’s not the faculty room, you know."

A chuckle, a joyful laugh at my unintentionally strained voice.

"Come in. You can come in."

"Y-Yes…!"

‘Come in,’ she said, and there was a moment of hesitation… no, maybe two seconds.

But, standing here frozen wouldn’t get me anywhere. So, I steeled myself, grasped the doorknob, turned it firmly, took a deep breath, and stepped forward…

"Welcome back. Are you all warmed up?"

"……!!"

The sight that jumped into my eyes at that moment made me jump back half a step.

Because what was there was…

Familiar wallpaper. Familiar bookshelves. Familiar chair and desk. Familiar, mysterious Gonzaburo-san. Familiar bed, and Senpai sitting on it.

And…

Senpai, in a single, oversized dress shirt that I definitely didn’t recognize!!

"Wh-Wh-What! Se-Senpai…! Wh-Wh-What…!!"

Could it be her father’s?

The clearly long sleeves were folded up two, three times, the hem was hiding Senpai’s dazzling thighs at just the right spot, and the neckline, with two buttons undone, was revealing her collarbone and chest, and the northern hemisphere of her breast’s hill as if emphasizing them… wait, she’s not wearing underwear under that, is she!!

"Why are you dressed like that!"

"Hmm? I always dress like this after a bath, you know?"

"Th-That’s a lie! Definitely a lie! You were wearing a cute fluffy pajama before!!"

"Did you prefer that? Should I change then?"

"N-No! Please don’t take it off!!"

"We were just naked together a while ago, weren’t we?"

"N-No! Th-That’s! Y-Yes, but!!"

Seeing someone naked and seeing them undress are completely different!!

No, I’m not confessing my fetish!!

"Boys of your age are difficult, aren’t they?"

"G-Girls of your age are difficult too, you know!"

"Hmm? Are you talking about me?"

"Who else would I be talking about but Senpai!!"

"Hmph… I see… so you’re properly treating me like a girl."

Senpai nodded as if she found it interesting, and then her cheeks softened with a strangely happy smile.

Looking at that smile, the flustered feelings vanished, and even I started to feel happy.

"Y-Yes, of course. Senpai is a girl. To me, you’re… that… very important… beloved…!"

Words that weren’t like me at all just spilled out, and I felt my cheeks flush hot.

"I-Is that so… that’s… um… thank you… is that the right response in this situation…?"

And Senpai too, her cheeks dyed red at my words, was shyly averting her gaze, looking unusually troubled.

"Well, then…"

"Ahem…"

Such an awkward, yet not at all uncomfortable, strange atmosphere.

We glanced at each other, not knowing what to say, trying to open our mouths and then closing them, and opening them again after closing them, a strange atmosphere where we could only say ‘ah’ or ‘uh’ drifted between us.

"F-For now, why don’t you come over here? Instead of just standing there."

"Ah, y-yes…"

Invited with an awkward smile, I entered the room.

And, I sat down on the bed that Senpai indicated… next to Senpai.

"Um… a little… c-closer… is it okay…?"

I was still being a bit reserved and keeping about one person’s width of distance, but Senpai glanced at me and gently patted the space right next to her, pon pon.

"Y-Yes…"

Following her words, I moved a little closer. Maybe about 1/4 of a person’s width.

"Hehe… you’re being too reserved."

"S-Sorry."

Then, saying that, Senpai moved closer to me by about 1/4 of a person’s width again.

"……"

"……"

Hot gazes. A distance so close I could hear her breath.

While our eyes were locked, I wasn’t satisfied with just that, and I placed my hand on Senpai’s hand that was on the bed…

"Senpai…!"

"……!!"

And then, I closed the remaining 1/2 of the distance in one go.

Hand in hand, our bodies pressed tightly together.

The distance between Senpai and me became zero.

"Shou… nen…"

Senpai’s cool hand gripped mine back tightly, as if responding to me.

Her hot, hoarse voice trembled as if expecting something.

My heartbeat and Senpai’s heartbeat synchronized at a speed like a frantic drumbeat, and in time with that, we stared intently at each other, and without either of us initiating, we brought our faces closer…

"Mmm…"

A soft kiss.

A kiss that we had exchanged countless times, over and over again.

But it’s not something you can get used to, rather, with each time, the melting sensation increases, making you feel like it’s still not enough, still not enough, increasing the addictiveness…

"You’ve gotten good at kissing…"

"Really…?"

"Yeah, at first you were quite clumsy, but you’ve gotten quite skilled."

"Skilled…?"

I don’t really understand. I’m always giving it my all, and it feels more like Senpai’s experience is increasing…

"More…"

While I was thinking about that, Senpai gently closed her eyes and pouted her lips.

"Yes."

So, I responded to her request and pressed my lips against hers again.

"Mnn… hmph… more…"

"Yes…"

"Aah… mnn. Haa… moooore…"

"Ye…s…"

Chup, chup, chup, kissing many times with small sounds.

Each time, Senpai would twitch, twitch, let out a sweet sigh, her eyes would moisten, and she would grip my hand tightly.

"Haa… hmph…"

"S-Senpai?"

As if her strength had given out, Senpai collapsed onto the bed. I慌ててtried to support her, and the position became such that I was kind of covering Senpai.

"Ah…"

The buttons of her shirt had come undone sometime, and Senpai’s beautifully shaped breasts were exposed.

The twin orbs were slightly flattened by gravity, but still pointed perkily upwards.

"It’s… okay?"

"Huh…?"

I didn’t understand for a moment what ‘okay’ meant.

"You’re slow, aren’t you…? Do I have to say it this much for you to understand…?"

Even as Senpai murmured that shyly, I still didn’t immediately realize it.

"I’ll say it one more time…? Today, my dad and mom are both not home, you know. They’re staying overnight, so they won’t be back tonight. It’s just you and me. If I say that much… you understand, right…?"

"Ah…!"

And, after a short pause, I finally realized.

"Eh, ah, um, um…"

Hesitating at this point, Ichinose and the others would probably say something.

‘Be a man and get a grip,’ maybe I’d get scolded by Senpai’s friends, Yotsuya-san and Gotou-san.

But…

"Um, well… I don’t have any…"

"Any what…?"

"Um… you know… condoms…"

Ah, if only I had taken one from Ninomiya.

When he said, ‘Here, take this as a charm,’ I shouldn’t have refused out of embarrassment.

"Oh… is that what you mean…"

Senpai’s face flushed red, but she smiled as if relieved.

"Shounen, you’re a good boy."

"N-No, it’s not like… it’s just that… these things, you have to do them properly…"

"No, that’s not true. You’re a very good boy. You’re properly thinking about me."

Senpai grinned, a full smile spreading across her face. It wasn’t her usual ‘mischievous smile,’ but a very girly, breathtakingly cute expression.

"Th-That… that drawer… it’s in there."

"Eh…?"

"So, um… condoms…"

Ah…!

Understanding the meaning of Senpai’s words, this time my face flushed hot.

"Th-That… those too… were they from Yotsuya-san and Gotou-san…?"

"That’s… I bought them myself, at the drugstore…"

"──────!!"

Senpai!?

Senpai bought them herself!!??

Imagining Senpai, always so cool, standing in line at the drugstore register with a bright red face…

I got excited. Terribly. So much that it was unbearable.

"……"

I slowly stood up and opened the drawer Senpai told me about.

"……gulp"

The silver package inside said things like "Super Thin!" and whatnot, but I didn't have time to read any of that.

"Um… do you know… how to put it on…?"

"Ah, well, y-yes… probably…"

Taking one of them out, opening the package, and taking out my fully prepared… thing… from inside my sweatpants…

"I’ll… put it on for you."

"Eh!?"

"Because… I practiced…"

"P-Practiced!?"

Senpai!? For me!? Practiced putting on a condom!?

"I don’t know if I can do it well, um…"

Just those words alone made my… thing… even hotter.

"H-Hey… hasn’t it gotten even bigger than before?"

My… part… was erect, throbbing and rock-hard, to the point that even Senpai was surprised.

"I-I’m sorry…"

"It gets this big, huh…"

"It’s because… I like Senpai too much…"

"Ah ha… I don’t mind it."

Her cheeks still flushed red, she chuckled softly and gently reached out her hand to my… you-know-what.

"Mnn…"

"Like… this…? Maybe…?"

Supporting the base, she pressed the condom to the tip and slowly rolled it down…

"Ah… unh… aah… nngh…!"

"D-Done…?"

"Y-Yes…!"

Truthfully, just having her put it on was enough to make me almost ejaculate, but I held back with all my might.

The softness and coolness of Senpai's hand, the warmth of her breath, her moist, glistening gaze – everything excited me.

"Um… Shounen."

"Y-Yes…?"

"Is it okay if I… put it in?"

"Eh…?"

Senpai murmured as she leaned over me, who was sitting on the bed. We were in positions reversed from just a moment ago, and we were both letting out hot breaths…

"F-For the first time… it’s better to do it at your own pace, Yotsuya-kun said…"

"I-Is that so…?"

Ichinose and the others had told me, "The man should lead!" but apparently that wasn’t the only truth.

"According to Gotou-kun, it’s good for boys to be steady and receptive…"

For a moment, I weighed my classmates against Senpai’s friends, and Senpai’s friends won. Somehow, those two felt more reliable than the guys in our class.

"I-I see…"

"So, you… just stay still…"

Senpai put her hands on my shoulders and hesitantly took a position as if leaning over me.

"Hah… ungh… huff… huff… huff… Nn…"

"Ah…! Senpai’s… place… is so hot…"

"Shounen’s is… haa… amazing too… ah… it’s like it’s going to burn me…"

Pressing her moist and open… place… against my… you-know-what…, she wiggled her hips and let out hot breaths.

"Th-Then, I’m going to… p-put it in… okay…?"

"Y-Yes."

My… you-know-what… was becoming soft and melting with the sweet nectar overflowing from Senpai's… place….

Pressing the meltingly hot entrance against my tip, Senpai took a deep breath.

"Ah… nngh…"

"Ugh…!"

Just the tip being swallowed was enough to send shivers through my entire body.

"Ah… hah… unh…"

"D-Danger…! This is… dangerous…!"

The sticky, seductive flesh enveloped my tip, conveying a slippery sensation and heat that felt like it could burn me.

"Sho…unen… just… a… wait… a moment… okay… augh…"

Would my thing really fit inside? Senpai's entrance was so small.

She gently moved in circles, like drawing circles, gradually getting used to it, gradually swallowing it, and slowly, slowly, lowered her hips…

"Ah…! Ah…! Amazing…! Amazing…! Shounen’s… thing…! Inside my… place…!"

"Ugh…! Uaaaaah! Hot…! It’s hot…! Melting…! Mine…! It’s melting!!"

Squish, squish, slowly, slowly, my… you-know-what… sank into Senpai’s… place…. Senpai accepted it, letting out panting breaths.

"More… ah… more… deeper…"

"Se-Augh! Senpai…! D-Don’t push yourself… too much…!"

"Ngh! Ungh! Uuuuuuungh!!"

Squish squish squish squish!

And then, my… thing… was swallowed all the way to the base in one go.

In that instant, the slippery folds of flesh inside Senpai's… place… entwined around me, squeezing tightly, wriggling as if to guide me deeper, deeper inside.

"S-Senpai! Blood…"

"Ah… hah… haugh… nngh… nngh… haha… well… it’s the first time… so… you know…"

A single streak of red ran down from the entrance of her… place…, which was stretched to its limit, swallowing my… thing…. Senpai’s proof of her first time.

"Ha… haha… ha… I’m happy… Shounen… to give you my first time… nngh… I’m so… happy… yip…"

"Senpai…"

I was thrilled.

Her brave words made my heart clench, and at the same time, I felt even more blood rushing to my lower body.

"I… is it… bigger again…? Nngh…"

"I-I’m sorry, Senpai…"

"Ah… hah… haha… it’s okay… don’t apologize… nngh… it’s okay…. This means… with my body… you’re feeling good… right…?"

Senpai's smile was mixed with a little pain. At the same time, Senpai’s… place… also spasmed, clenching tightly around my… thing… with a squeeze, squeeze, squeeze feeling.

That feeling was wonderful, and Senpai, being so happy about it, was so cute, I felt happy, fulfilled, and things were just becoming incomprehensible…

"Just a little… ungh… I’ll try… moving… okay…?"

"Eh, w-wait, are you alri— ugh!"

Before I could stop her, Senpai slowly raised her hips and then lowered them.

"Ngh…! Ah…! Augh…!"

The clinging flesh walls moved as if pulling my… thing… up, and then swallowed it again with a squish, squish sound.

"Hah… ungh… nngh… does it feel… good…? Does it feel good?"

"Fee— ah…—ls… nngh! Good…! It… does…!"

Being squeezed tightly inside Senpai's incredibly narrow… place…, being caressed with squish, squish sounds, it was hot, and numbing, and my hips were twitching.

But, Senpai was…

"Ah… hah… are you… worried…? Nngh… about me…? Nngh! You really are… so kind… nngh…! Nnngh!"

"Because… nngh… because… augh…! I don’t want to be the only one feeling good…!"

I don’t dislike feeling good. In fact, I like it. What we’re doing right now feels amazing. But, but, I want to feel good together with Senpai. I don’t want it to be just me.

"I’m… fine… don’t worry… nngh… no need… aha… I also… you know… somehow… the pit of my stomach… ah…! Is getting all fluttery… hah… more… ah… more… with your… thing… ah… I want to be… thump… thump… thrust into… ah! Ungh! Augh!"

A sweet, seductive voice escaped her lips.

At the same time, the flesh walls squeezed my… thing… even tighter, spasming as if to guide me even deeper.

"I-It’s okay… nngh… it feels… ah… good… so… augh…! Thru—st…! Deeper…! Thump thump…! Thrust!"

"Sen—pai! Senpai! Senpai!"

The limiter came off. The shackles that had been holding me back somewhere broke with a sound.

Responding to Senpai’s sweet, poignant, and bewitching voice, I, I slowly, little by little, started thrusting my hips up…!

"Ah! Ah! Ah! Amazing…! Shounen’s… thing…! Thumping deep inside me…!"

"Uagh! Uaaaaaah! Senpai’s… place…! Inside her… place…! Squirming and wriggling! Squeezing mine tight! Ah! Nngh! The tip…! Kissing… kissing my tip…!"

Rising pleasure. Rising excitement. Senpai and I matched our rhythm, becoming one, writhing our hips, our breaths ragged, kissing each other chup, chup countless times, getting more and more aroused…

"Nngh…! Ah… augh…! Shou—nen…! Shounen…! Makoto-kun! Ah! I’m…! I’m gonna…!"

"I’m…! Me too! Senpai! Senpai! Me too! I’m! Gonn—a! Come! Cumming!!"

"Ah! Ah! Ah! AAAAAAAAAAAAAAAAAAAH!!"

Thump, thump, thump, thump

Finally, it burst.

"Ah! Hah! Augh! Twitch… nngh… Shounen’s… thing… is… hah… twitching…!"

"Augh…! Senpai…! Your… place…! Squeezing…! Squeezing… tight…!!"

Senpai's seductive flesh spasmed, squeezing my… thing… with extraordinary strength and intensity. With that pleasure, I felt as if every last drop was being squeezed out of me…

"Haa… haa… haa…"

Senpai collapsed onto me as if falling apart.

"Hah… hmph… Shou…nen…"

"Senpai…"

I gently hugged Senpai’s body, damp with sweat, and gave her a soft chup kiss.

◇　◇　◇

How much time had passed since then?

"…That hurt."

As we lay exhausted in bed, Senpai suddenly murmured. Her voice, slightly resentful, had a slight nasal tone.

"I-I’m sorry…"

"…I’m not blaming you. I’m just savoring the experience of something I only knew about in theory."

But, Senpai gave me a gentle smile, shaking her head at my apology.

"The first time was painful, just like I’d heard. But… it was also much more pleasurable than I’d heard."

"Senpai…"

"Being loved by you makes me very happy. I’m sure today’s pain will become a precious memory for me. So… I should thank you. Thank you."

My heart clenched.

Hearing her say that, I was so happy that I didn’t know how to respond.

So…

"Um, well, I, I was also… I was also happy. Being able to be like this with Senpai… it’s like a dream."

"A dream, huh… yeah, it does feel like a dream. But… if this is a dream, and if I wake up and it’s no longer real, I’d cry."

Senpai gently reached out her hand. I gripped it tightly.

"So… to make sure I don’t mistakenly think it’s a dream… will you stay with me a little longer?"

"Yes… of course…"

A slight weariness and at the same time an overwhelming sense of happiness. I knew that if I were alone right now, I wouldn't know what to do with this feeling… Senpai’s words were exactly what I’d hoped for.

"Let’s take another bath later."

"Yes."

"No more naughty stuff, okay?"

"Eh… y-yes."

"Hehe… just kidding. Don’t make such a disappointed face. Let’s do even more naughty things."

On this day, I experienced my first overnight stay outside of family trips and school events.

I have to thank Ichinose for helping me with my alibi…
