Chapter 1
On the day of my birthday, I was conscious of being restless since morning.
I thought it was pathetic and like a small child, but please forgive me since this year is truly special.
"Haha, you're really restless, aren't you?"
"Kaito..."
Kaito, who was munching on an ice cream right beside me, was laughing.
"Sorry... it's not like I'm not enjoying this, okay?"
"I know that. But for us, it's interesting to see Hayato being all restless like this, so it's totally fine."
"......'Interesting' is unnecessary."
Hmph. I looked away from Kaito and bit into the ice cream I was holding.
Perhaps because I took too big a bite, a sharp pain shot through my head, and I reflexively clutched my forehead. Kaito laughed at me for that too.
"Hey, you're laughing too much."
"Sorry, sorry."
This guy definitely isn't sorry!
Even when I glared at him quite intensely, Kaito's expression didn't change, and he was thoroughly enjoying the current situation.
"It's fine, isn't it? When it was my birthday, you and Sota teased me like crazy, and when it was Sota's birthday, it was me and you."
"......Well, yeah. I guess we're even."
Honestly, no matter how much it’s a birthday, people usually wouldn't go that far.
Still, it’s precisely because the three of us are so close that we want to celebrate a best friend's special day even if it means teasing them to death... That's a feeling we all share.
"You know."
"Yeah."
"Are we too close?"
When I asked that, Kaito grinned and nodded.
"A bit late for that, isn't it? Besides, there's no such thing as being too close. Fighting occasionally might be good, but we don't even have that unless something major happens."
There’s a saying that people are so close they fight, but we haven't really fought since the time we first met... and even that "fight" wasn't violent, it was just a verbal argument.
"By the way, isn't Sota taking a long time?"
"Well, it can't be helped."
By the way, Sota was with us too, but his stomach had apparently started hurting just a little while ago. He’d clutched his belly and ran to a nearby restroom, so we were waiting for him... It seemed like a pretty tough case of stomach pain.
"Sota really has a weak stomach... is that just his constitution?"
"Probably. He gets nervous easily too."
After chatting for a bit while he wasn't there, Sota finally returned.
"Man, sorry, sorry. I feel refreshed now."
"Welcome back."
"Yo~"
Now that Sota was back, we finally started walking again.
Well, it was almost five o'clock, so it was about time to head our separate ways.
"Somehow... fun times really fly by, don't they?"
The words slipped out of my mouth as a murmur.
After the homeroom ended, I said a word to Arisa and Aina and then immediately left school with Sota and the others. We’d enjoyed karaoke and bowling until just now, but time had truly passed in an instant.
Both while bowling and during karaoke, I’d thought many times how I wished this fun time would last longer.
"Which is more fun: the time you spend with us, or the time you spend with the Shinjos?"
Sota asked that while putting his arm around my shoulder.
I thought he’d asked a rather mean question, but I took a bit of time to think about it seriously... and I answered like this.
"To be honest... I can't say which is better."
"Eh?"
"......Why?"
"Hey, what's with that reaction?"
The two of them widened their eyes when I said what I’d thought through.
Um... did I say something strange?
"I mean... wouldn't it obviously be the time with your girlfriends?"
"Yeah, yeah. It's not even something you need to think about, or compare."
......Ah, I see.
Sota and the others meant that spending time with my precious girlfriends should be more fun than spending time with my best friends like this.
I gave a bitter smile, wondering what they were talking about, and spoke my true feelings.
"The time with Arisa and Aina... of course it's precious and fun, you know? But for me, Sota and Kaito are also my best friends... truly important best friends, and the time we spend playing together is always nothing but fun."
"Hayato..."
"It’s not on a level where I can compare which is better... Just like Arisa and Aina, Sota and Kaito are also important existences to me—it's a bit embarrassing to say, but that's how it is."
I scratched my cheek as I suddenly felt embarrassed, but it was all my true feelings.
It's obvious that Arisa and Aina are important, but these guys, my best friends, are also important to me.
"I mean, I'm answering seriously, but isn't it like that for everyone? Not just while we're students, but even after we become adults, I'm sure we'll still be getting together to eat... and definitely to drink and stuff."
The words wouldn't stop, to the point where even I found it strange. Sota and Kaito were staring at me blankly... Their stunned expressions were a bit funny.
"..............."
"..............."
"......Say something."
Even if I’d said what I wanted to say, it was troublesome if there was no reaction...
Just as the atmosphere was becoming unbearable, the two of them finally moved and put their arms around my shoulders.
"Good grief, when did this guy start saying things like that?"
"Aren't you embarrassed? Well, but... we feel the same way, don't we?"
"Yeah, it's the same for us, Hayato!"
"Right. There's no doubt about it!"
"H-Hey, that hurts!"
The strength of their grip was unexpectedly strong, and I complained. But neither of them seemed to care at all and only squeezed harder... Being treated with such joy made me lose the will to keep complaining, let alone shake off their arms.
In the end, I guess it means I also like physical contact with my best friends.
"Hayato, happy birthday again."
"Be prepared, 'cause we're gonna celebrate next year too~!"
"......Yeah, thanks."
Receiving those final parting words, we went our separate ways.
After parting with the two of them, my destination was, of course, the Shinjo residence. In a sense, today's main course was just beginning.
"It might be strange to say, but... I already feel such a sense of satisfaction."
Even though the main event was still ahead, I was incredibly satisfied. Last year, I’d felt an indescribable emptiness at this point.
I mean, it’s obvious, isn't it?
No matter how much fun I had, I would be alone once I got home... Even if my grandfather and grandmother called to wish me a happy birthday, the time after that was always spent alone.
"......But this year is different."
Yes, from this year on, it’s different.
Of course, Sota and Kaito had told me to come over to their houses if I was lonely at night, and their parents always looked out for me too.
I was happy about that, and I did consider taking them up on it, but in the end, I’d always held back... But as I said, this year is different.
Since I'm planning to stay over there today, I won't be alone at night... I don't need to harbor that sense of emptiness I’ve always felt.
"Well then, let's get going!"
I hurried along the road toward the Shinjo residence, trying to suppress my racing heart.
▼▽
“...I’m sweating like crazy.”
By the time I reached the Shinjo residence, I was drenched.
Even though the peak of summer had already passed, the temperature remained high day after day... Plus, it had been stiflingly hot earlier when those guys were throwing their arms around my shoulders.
“...Phew.”
I let out a breath to steady my nerves and rang the doorbell.
Immediately, I heard the sound of heavy footsteps. The door swung open, and she—Aina—showed her face.
“Welcome, Hayato-kun.”
“Hey.”
“Uey~i!”
“Whoa...”
Aina lunged at me in a surprise attack, and though I caught her, she buried her face in the crook of my neck. After sniffing me for a moment, she gave me a lick.
I squirmed at the ticklish sensation and tried to pull her away, but she wouldn't budge... For a while, I had no choice but to endure her licking time.
“That was delicious♪ Thanks, Hayato-kun.”
“Delicious, huh... Well, you’re welcome, I guess?”
“I really do love your sweat, Hayato-kun. Just smelling it makes my body get all ready, but once I lick it, well... you know♪”
She whispered into my ear and proceeded to wrap her leg around mine. Like a spider binding its prey in silk, Aina pinned me down as if to say she would never let me escape.
“Ehehe... We talked about this during lunch break before, but you’ve never thought of this as a bad thing, right, Hayato-kun? In all the world... we’re only lewd like this for you, and you absolutely love it, don't you?”
She already knew the answer... And yet, asking with such absolute confidence made her incredibly cute and charming... and, as expected, erotic.
“...I love it.”
Consequently, I had no choice but to answer that way.
Aina’s smile deepened even further as she unbuttoned the top of her shirt... The valley of her massive breasts—which had grown even more lately and were nearly reaching the triple-digit mark—peeked out at me.
That cleavage... Even just the upper portion of her breasts possessed an allure that overwhelmed me.
It wasn't just Aina; Arisa was the same. Despite having such enormous breasts, their shape was incredibly beautiful... and the texture was exquisite. I often found myself thinking I wanted to knead them forever... Wait, what am I thinking at a time like this!
“Hey, Aina... let’s get inside already, okay?”
“Ehh? You’re going to say that after getting a girl this worked up?”
“...Wait, am I the one in the wrong here?”
“Mh-hm. I’m the one who’s wrong for being so lewd... but you know? The one who’s even worse is Hayato-kun for making me this way... It might be unreasonable, but it’s the fault of the Hayato-kun who loves me.”
Unreasonable... For me, this was the kind of "unreasonable" that made me happy.
Seeing Aina like this made me want to be a little mischievous myself. I leaned my face close to her, as she radiated an erotic aura, and gave her a somewhat forceful kiss.
I say forceful, but her mouth opened easily to accept my tongue. Before long, we were desperately entangling them, exchanging saliva... However, since this was meant to be a prank, I pulled away quickly.
“Whyyy~?!”
“That’s as far as we go for now.”
“...Hmph!!”
Aina puffed out her cheeks in a massive pout, looking utterly dissatisfied.
Thinking her expression was adorable as always, I practically dragged her along as we finally entered the living room.
Inside, not only was Arisa there, but Sakuna-san was as well.
“You’re quite late, aren't you? I wonder what you were doing...”
“Fufu, isn't it fine? Welcome, Hayato-kun.”
My cheeks relaxed at the sight of them welcoming me with smiles.
However, the birthday party didn't start right away. Since I was covered in sweat, I was offered the first bath.
While soaking in the tub, I anticipated that either Arisa or Aina—or perhaps both—might come charging in, but it didn't happen in the end... I’ll keep it a secret that I was actually a little disappointed.
“Hayato-kun? By any chance, were you wishing we’d joined you in the bath?”
“I-I don't know what you’re talking about...”
“Ahaha! You’re so easy to read!”
Umm... Why do they notice things I haven't even put into words?
They probably both think I’m a pervert, but I can say with my chest out that they are far bigger perverts than I am, you know?
Right, Sakuna-san?! ...Well, it’s not like I can ask their mother something like that!
“Arisa, Aina, what are you two doing about your bath?”
“We’ll go later.”
“Yeah, let’s do it after dinner. We’re just going to get dirty again soon anyway♪”
We’re just going to get dirty... They really just come out and say things like that, don't they?
After watching us with an amused look, Sakuna-san clapped her hands together.
“Well then, let’s finish up the preparations for dinner. Arisa, Aina, can you help me?”
“Of course.”
“Let’s get it done quick!”
Ah... it was my turn to—or rather, I wanted to help too!
Just as I thought that and tried to stand up, something wondrous happened. With perfect coordination, Arisa and Aina each placed a hand on my shoulders and forced me back down, as if telling me to stay put.
“Listen, Hayato-kun, you’re the guest of honor today.”
“That’s right, so just wait for us, okay♪”
...Well, if that’s how it is, I’ll wait patiently.
As I waited for the preparations to be finished, I felt satisfied just watching the dishes being completed one by one.
Granted, my stomach was growling in response, but the current situation made me feel truly happy from the bottom of my heart—and then, the table was set with a multitude of luxurious dishes. The preparations were complete.
“...Ohh.”
The food had been luxurious during Arisa and Aina's birthday, but this was easily on par with that. When I thought about how they had prepared all of this for me, my resolve to wait until after it was over to cry began to waver.
“There you go, Hayato-kun. Dig in♪”
“There’s cake too, okay? And the presents are something to look forward to after dinner♪”
“Yeah... Yeah!”
Seriously... I’m so happy, Arisa, Aina.
Not to mention the two of them smiling right beside me, Sakuna-san was also smiling gently as she watched us. The room was filled with warmth and kindness.
“...Well then, itadakimasu.”
I pressed my hands together and began to eat the food everyone had made for me.
Calling it "luxurious" or "extravagant" might not be quite right—to me, every dish lined up here was filled with love and sincerity... Man, what am I even saying?
“How is it?”
“Is it good?”
“Yeah, it’s delicious.”
The taste, the aroma—everything was top-notch. I couldn't stop eating.
There was a huge chicken, sushi, salad... there were so many other dishes, and I wanted to pack every single one of them into my stomach.
“My... Hayato-kun?”
I was smacking my lips and repeating how delicious it was, but then Sakuna-san called my name with a worried tone.
Wondering what was wrong, I looked up to see that not only Sakuna-san, but Arisa and Aina were also looking at me with concern... But I realized the reason immediately.
“...Ah.”
Tears were streaming down my cheeks... It seemed I couldn't hold back my emotions after all.
There was another day before when I had cried during a meal in such a warm atmosphere, but I didn't think I was quite this much of a crybaby... Anyway, I have to tell them with a smile that there’s no need to worry!
“U-Um, I’m totally fine! Like before, I’m just so happy to have my birthday celebrated like this! Family... it just hit me again that I have a family who celebrates with me now—”
I thought... I was supposed to finish that sentence, but the words were cut off midway.
That was because my face was buried in a pair of large breasts as I was pulled into a hug... And it wasn't Arisa or Aina, but Sakuna-san, who seemed overcome with emotion.
“I’m sorry. I just... wanted to do this.”
“...Good grief, she beat us to it.”
“Seriously. Well, let’s let Mother have this one♪”
Truly... what a warm place this is.
A place I want to protect forever... A place I want to stay forever... A place where I want to feel this peace forever... I want to keep protecting this place where Arisa, Aina, and Sakuna-san are.
“...Mom.”
“...Fufu, yes, I’m your Mom.”
I only ever call Sakuna-san "Mom" during these special moments when my emotions are overflowing... It’s probably a rare occurrence, but Sakuna-san looks so happy whenever I call her that.
“Listen, Hayato-kun, your mother will do anything for you, okay? Anything you wish for... anything at all, you hear?”
“...!”
The words whispered into my ear made the strength drain from my body for a moment.
As I leaned my full weight against Sakuna-san’s body, I sank deeper into the depths of the breasts cradling my face.
“...I feel so at peace.”
“Then let’s stay like this for a while.”
Sakuna-san’s words were no lie.
From then on, for about five minutes... I became a resident of Sakuna-san’s chest.
I was curious about what kind of faces Arisa and Aina were making, but Sakuna-san’s sweet, maternal embrace was so powerful that those thoughts were almost wiped from my mind... I even found myself thinking it would be fine to just fall asleep like this, forgetting that we were in the middle of a meal.
“...Um, thank you, Sakuna-san.”
“My, aren't you going to call me Mom anymore?”
“...If I call you that too many times, won't it lose its value?”
“How could it? A mother always wants to be called that by her child.”
Saying that, Sakuna-san spread her arms, taking a stance to accept me once more.
Unconsciously, I was about to dive back into her chest, but the ones who—as expected—wouldn't allow that were none other than the sisters.
“Excuse me, could you please stop creating a world for just the two of you?”
“Yeah! We gave Mother the first move, but no monopolizing him!”
Even though they had just said they’d let her have the turn, both of them were now glaring at Sakuna-san with intense rivalry. Sakuna-san tried to settle the situation with her usual smile, but... eh?
“Hayato-kun, are you satisfied yet? If it’s not enough, I can give you more, you know? Come on, dive into my tits♪”
Sakuna-san isn't backing down at all today...?!
As Sakuna-san said that while throwing a provocative smile at her daughters, Arisa and Aina were practically growling and hissing in intimidation... They were incredibly cute.
“Hayato-kun.”
“Whose tits...”
“...do you want?”
Even if you’re going to compete, why over that?!
With my arms being hugged by Arisa and Aina and Sakuna-san right in front of me... For a moment, the three pairs of breasts slowly and steadily sandwiching me and closing in were actually a little scary.
“U-Um...”
Still, I’m the only one who can settle this!
The answer they were seeking was whose breasts were the best... If I just answered that, I could bring this situation to an end for now!
Come on, don't mess up the answer... Don't you dare mess up, me!
“...I love everyone’s tits.”
“...Everyone’s.”
“Tits...”
“...You love them, do you?”
By the time I thought "uh-oh," it was already too late. But thinking about it calmly, was there honestly any other answer...?
I felt a flash of anxiety, but it was immediately proven that my answer wasn't wrong in this situation—as I was enveloped by the breasts of Arisa, Aina, and Sakuna-san all at once.
“Mugaga?!”
“Well, it can't be helped, I suppose.”
“I guess so... Let’s all give him a puff-puff together♪”
“Ufufu, Hayato-kun really is adorable.”
Surrounded by six mounds of flesh, my head was under a blissful state of pressure.
Sandwiching me from the left and right were Arisa and Aina’s breasts, and from the front were Sakuna-san’s... Not only was the elasticity amazing, but they smelled so good that I thought I wouldn't even mind dying right then and there.
“Mother, your tits really are huge.”
“My, look who’s talking.”
“They’re small compared to Mother’s, right? Well, both Nee-san and I have the kind of big tits Hayato-kun likes, though♪”
Arisa and Aina both know I like big breasts, but could you please not say it here?! It’s incredibly embarrassing!
For a while after that, the time continued with embarrassment and happiness living side by side.
However, since we were still in the middle of dinner, we all laughed and reflected on how we were being ill-mannered before resuming the meal.
And finally, the cake was brought out.
“Ohh... it looks delicious!”
The volume was impressive, but the generous coating of chocolate was spectacular.
There were fruits like strawberries and grapes. And in the center was a large cookie decorated with my name and the words "Happy Birthday."
That would have been enough on its own, but they had even prepared candles.
Seventeen candles, matching my age, were lit. Once she finished lighting them, Arisa smiled and gestured toward me.
“Hayato-kun, happy birthday!”
“Happy birthday~!”
“Happy seventeenth birthday, Hayato-kun.”
“...Sniff.”
Oh no, the tears are coming again...!
If I cry here, I’ll be given another gentle embrace, starting with Sakuna-san... Not that that would be bad at all, but if that happens, I don't know when I’ll ever get to the cake, so I have to hold it in!
“Thank you, everyone... Well then, phew!!”
After offering my thanks, I blew at the candles with all my might.
I wanted to blow them all out in one go since I was at it, but unfortunately, my breath didn't hold out, and one remained.
“Kuh... so close.”
“Ahaha! Your face is bright red!”
“It’s like you ran out of oxygen.”
Seriously, I was actually a little out of breath.
Getting my act together, I blew out the last candle, and we all ate the cake while chatting and making a fuss.
After finishing dinner and the cake, Arisa and Aina came over with a present.
“We picked this out together.”
“I hope you’ll be happy with it... though it’s something that makes us happy too.”
“Oh?”
A present for me that makes the two of them happy too... I wonder what it is.
I knew they were preparing a return gift for the stuffed animals I had given them before, but I was already so satisfied with the birthday wishes and the food... I almost felt bad for receiving anything more.
“Here you go.”
“A present from both of us!”
“Ah, thank you, both of you!”
Now then, I wonder what the present they prepared is~♪
I carefully peeled off the wrapping paper and opened the box inside... What came out was a beautifully crafted photo frame.
“Oh, a photo frame.”
“We thought you could use it to display photos of our memories.”
“It’s pretty stylish, right? You can use photos we already have, or photos we take from now on!”
“Haha, so that’s why it’s a present that makes you two happy too.”
The moment I received this frame, it became a memento, but the photos I’d display in it would also be filled with memories... And of course, they would be in those photos too.
“...Even if you don't display a photo, just having this in Hayato-kun’s room makes me satisfied.”
“I... I really get that.”
“Yeah, yeah! I know the feeling!”
Right, right!
That’s just how it is when you get a present from someone important!
“Arisa, Aina... thank you so much. I’ll treasure it... I’ll display the best photo of us in here.”
“Yes♪”
“Mhm♪”
The smiles of the two as they nodded... that was also the best present.
I’m satisfied... I’m truly satisfied today! I keep saying it, but I really am!
“Hayato-kun, I have a present prepared as well.”
“Eh?! Sakuna-san too?!”
W-Wait a minute.
If I’m made any more satisfied than this, I’m going to lose it...
The bag Sakuna-san brought was larger than the sisters', but when I took it, it was quite light... Is this a belt?
“I chose a design that can be used with both your school uniform and your private clothes.”
“This is great! Thank you so much, Sakuna-san!”
“Fufu, I’m glad you like it. Well, I do have the feeling that I want you to wear something I chose no matter the occasion...♪”
I could certainly wear it anytime... no, I’m just really happy!
The words Sakuna-san spoke made my heart skip a beat, but the joy that followed was so overwhelming that I couldn't stop grinning.
Delicious food, including the cake, and wonderful presents.
I had been looking forward to today, and I had predicted that I’d be satisfied from the bottom of my heart... but I never imagined it would go this far.
“Arisa, Aina, Sakuna-san... thank you so much... I’m so happy... I’m incredibly happy!”
And as if on cue, it goes without saying that my tear ducts collapsed.
I tried to wipe away the overflowing tears with a tissue, but...
“My, why don't you just cry into our breasts?”
“That’s right, come here.”
When they put it like that, there was no way I could hold back. I shed tears of emotion in their breasts until I felt refreshed.
Now then, that concludes the birthday party they prepared.
I’m planning to stay over tonight instead of going home, but my night... my night with them is far from over.
“Tonight... it feels like I’m going to be the one wanting them more than they want me.”
The feelings smoldering in my chest were so strong I wanted to hurl them at those two.
Only a few days ago, I had told them that our days were becoming a bit too degenerate, but since I was feeling this way now, that must have been a meaningless worry.
“...Ah.”
It was while I was aimlessly looking around Arisa’s room since I had nothing to do.
On her desk sat a photo—one of just me, and another of me together with the sisters.
“...This is nice.”
Aina had displayed photos of me too, but seeing this made me happy all over again.
Even though it was a photo of myself, I was looking at it with deep emotion when the two of them finally returned.
“Sorry to keep you waiting.”
“We’re back♪”
With faces flushed from the bath, the two approached me.
Before I could even say "welcome back," I reached out my arms and pulled their slender bodies toward me at the same time, hugging them tight as if to say, "closer."
“Sorry, you two. I... I want Arisa and Aina so much I can't stand it.”
“Fufu, of course... right, Aina?”
“Yeah! After all, we haven't finished giving you your presents yet!”
"Presents" in this case meant, in other words, lewd service.
I had enjoyed myself to my heart’s content earlier, but I tasted the sensation and scent of their breasts through their pajamas once again... Ah, it’s no use—no matter what, I won't be satisfied with just this tonight!
“Hey, Hayato-kun.”
“Yeah?”
“I’m so happy you’re wanting us this strongly. But I told you earlier, didn't I? We haven't finished giving you your presents... From now on, Aina and I are going to give you the best present of all♡”
“That’s right! So Hayato-kun, just stay still, okay? For the time being, I want you to just leave everything to Big Sis and me♡”
To be honest, my desire to be the one doing the wanting hadn't changed.
But if the two of them were going to say that... ahaha, being able to worry about this is truly a luxury.
In that case, I’ll let myself enjoy this luxury to the fullest tonight!
“Well then, please sit on the bed.”
As soon as I sat on the bed as instructed, the two of them took off their pajamas.
“Ah... that’s!”
Underneath their pajamas was the "victory underwear" they had shown me a few days ago.
I could tell they definitely fell into the category of underwear, but given that they didn't even cover the tips of their breasts, could they even be called that...? Even if I gave them the benefit of the doubt, they were definitely erotic lingerie.
“It’s been since that day, hasn't it?”
“How is it?”
“They look good... they look so good on you.”
My vocabulary had vanished, but I had no regrets.
“They look good and they’re erotic... I mean, I never thought I’d be seeing a woman in underwear like this while I’m still in high school.”
“That’s something we thought too. But we’re wearing this because we want you to be happy.”
“It’s because we want you to get in an erotic mood. It’s because it’s you, Hayato-kun... because we love you so, so much♪”
The two sat down beside me as I sat on the bed.
I was about to receive "service" in the name of a present from them, but in this situation, not hugging them wasn't an option.
“Um, listen, I think you’ll both be mad if I say this, but...”
“My, can you really say something that would make us mad, Hayato-kun?”
“Eh? I wonder what you’d say to make us mad... saying 'let’s break up' would be more sad than making us mad.”
I would never say that.
I gave a wry smile at Aina’s words and spoke what I had been thinking honestly.
“Well... I’m so happy it feels like I could die anytime.”
“That is...”
“...not allowed.”
In that instant, I had the illusion that the world had frozen over.
I felt the piercing intensity of the gazes from the two sitting right beside me, and it was terrifying to even think about making eye contact with them.
I had never felt scared of them before, but I didn't know they could give off an atmosphere like this.
“Hey, Hayato-kun.”
“Y-Yes...”
“Even as a joke, there are things you should and shouldn't say, right?”
“...You are absolutely correct.”
“It was definitely a teasing way to put it, but that’s not funny, you know?”
“...I’m sorry.”
“Because it really made me sad.”
“Yeah... I’ll never say it again, I promise.”
My shoulders slumped visibly, but perhaps they panicked at how depressed I looked, because they immediately continued.
“S-Sorry, Hayato-kun! For you to get that down... um, I know it was a joke, okay?! But still... um...”
“I’m sorry, Hayato-kun! I know it was a lie! So... um, please don't hate me, okay?! You can suck my tits!”
The tables had completely turned, and we looked at each other... and because we knew it had been a joke, we were able to laugh together.
Now then, with that out of the way, it was finally time for their service.
The three of us were sitting on the bed, but Aina took a position for a lap pillow, so I placed my head on her thighs... Naturally, what hung directly in my line of sight were Aina’s burst-sized breasts, which were on the verge of reaching triple digits.
“Ehehe, I wasn't lying when I said you could suck them earlier. Well then, Hayato-kun, eat your fill.”
The breasts approached slowly and were pressed right against my mouth.
I caught a glimpse of Aina’s expression—it was gentle, as if she were looking at me like a small child... I love her usual cute expression and her little devilish look, but I love this gentle expression too.
“Hayato-kun’s tongue feels so good♡ When you do that, it makes me wish I could produce breast milk.”
“It’d be a disaster if you did.”
“Well, yeah, but don't you think that kind of play is erotic and something to admire? Don't you think Big Sis would want Hayato-kun to drink hers, or want him to squeeze them with all his might?”
“That’s... well, yes. Just imagining it is overwhelming.”
I started imagining it too from their conversation, and my already intense excitement became even more fierce.
Aina, whose breasts I was sucking, seemed to get even more into the mood as she pressed them against me, as if to cover not just my mouth but my entire face.
“Tell me if you can't breathe, okay?”
“No, I’m fine, it’s not hard to breathe at all.”
“Anhn♡ It’s ticklish when you talk while doing that... but I’m relieved then. Suckle them as much as you want♡”
I could have been satisfied with just the interaction with Aina, but Arisa moved as well.
She spread my legs and fixed them in a lifted position... in other words, she was in a position where she could sandwich me with her own breasts.
“Tell me, Hayato-kun, how do you feel?”
It was too good... it was so good I almost felt bad.
“I can feel your happiness from right here... Good grief, we’re something else, but you’re incredibly lewd too, aren't you, Hayato-kun?”
No... didn't I get this way because the two of you are so erotic?
“I can't see Hayato-kun’s face, but I bet he’s thinking this is all our fault.”
“My, my. It’s not exactly wrong, but isn't it your fault too, Hayato-kun?”
“That’s right. The reason we became this lewd is because we love Hayato-kun too much, isn't it?”
“It is. It’s because we met you, Hayato-kun, that we can't see anyone else, and we wanted you to like us... we wanted you to like us no matter what, and that’s why we ended up like this.”
The words they were saying made me happy... even if they were speaking in a slightly accusing tone, they were only saying things that made me incredibly happy.
There were limited ways for me to express that happiness.
After all, my face was currently being crushed by Aina’s breasts, and my mouth was as well.
Therefore, the only way to quickly express my joy was naturally through my mouth's actions against Aina’s breasts.
“Ha... I love that tongue work...♡”
“It’s gotten even more energetic over here too♡”
Above and below, I was enveloped by them, enjoying my happiness to the fullest.
But I thought that from an outside perspective, I must look quite embarrassing, or rather, ridiculous. Even so, the only emotion I felt was joy.
“Hey, Hayato-kun.”
Aina called out to me, and I made an "nn" sound as an answer.
“I watch erotic manga too, and you often see this kind of thing in harem series where there’s more than one heroine, right?”
Yeah... I was thinking the same thing.
“In a pure romance... in a relationship between lovers who love each other from the bottom of their hearts, we’re probably the only ones who can do something like this, you know? So we’re going to enjoy ourselves from the bottom of our hearts, and it’d be a waste if you didn't enjoy yourself too, Hayato-kun!”
I wanted to nod at Aina’s words, but I couldn't.
And so, with my face buried in Aina’s breasts as I listened to her talk, Arisa had been taking care of my crotch the whole time... and before long, I reached my limit inside Arisa’s breasts.
“Ngh...!”
“It’s throbbing inside my breasts... I love this sensation.”
“It’s great, isn't it? I love it too!”
Released from Aina’s breasts, my vision finally returned.
Arisa scooped up what was smeared all over her breasts with her hand and licked it all off to clean them.
“Aina is the same, but you two really are erotic when you’re doing that... sometimes you look much older than me.”
“That just shows how much of an erotic woman we are.”
“Only for you, Hayato-kun!”
This time I was able to nod properly.
However, even if I had finished one round, our night wasn't over yet.
“Now it’s my turn to do it... right here, of course.”
Aina, who had switched places with Arisa, slowly straddled my hips.
By the way, it seemed Arisa had put a condom on me at some point, so the preparations were complete.
This was a special present from them.
Today, I would just spoil them, just stay still and accept their love... this year’s birthday was truly luxurious, or rather, it felt like I was being made to experience the peak of happiness for an eternity.
“Aina, make sure you make Hayato-kun feel really good, okay?”
“Yeah! Well then, I’m putting it in♡”
And so, our night passed.
A night so intense, so happy, that I found myself wishing it would last forever... the night of my birthday spent with them.
▼▽
“...Phew.”
The time I spent drowning in sex with both Arisa and Aina had come to an end.
As always, it was a time of utter degeneracy... but as time went on, it flared up even more and was the best time.
“I... I can say with my chest out that I’m definitely the happiest high school student in the whole country.”
This wasn't just because of the erotic time with them, but also because of the relaxed time after we had finished.
We just snuggled up to each other softly, both of us naked.
The way they were touching me was a little indecent, but I wasn't looking for anything more, and we really just enjoyed a leisurely conversation.
“Suu... suu...”
“Munya... Hayato... kun...”
And now, I was looking down at the two of them sleeping.
After we finished, I had cleaned myself up and changed into pajamas, but they had stayed in their underwear, saying it was cooler that way.
Even though the erotic time was over, they looked even more erotic now, sleeping with such innocent expressions in that state... Phew.
“...What a beautiful starry sky.”
I looked away from Arisa and Aina and up at the sky full of stars.
Even though it had been cloudy and the weather had been terrible yesterday, there wasn't a single cloud today.
“With a night sky this beautiful... I’m sure my mother and father are looking at my birthday and celebrating for me.”
...Well, I only want them to be looking until we finish eating the cake, though.
“.................”
Even now, I still have a bit of a floaty sensation.
It wasn't because of the sweet yet intense time just now, but because I was able to spend today feeling more fulfilled than ever before.
After looking at the sky for a while, I left Arisa’s room and headed for the living room.
My throat was a bit dry and I wanted some water.
“...Sakuna-san?”
“My, Hayato-kun?”
I thought no one would be there, but Sakuna-san was.
Bathed in the moonlight by the window, Sakuna-san’s figure as she turned toward me was as beautiful and fantastical as a celestial maiden.
Come to think of it, this scene... I’ve seen something like this somewhere...?
“Ufufu♪ It reminds you of that night we went to the sea, doesn't it?”
“...Ah, come to think of it.”
Right... that was why I felt deja vu.
Sakuna-san beckoned me, so I walked over to her side.
Sakuna-san was wearing a robe over her nightgown, but as always, her revealing outfit made my heart race.
“Judging by your appearance, it seems you’ve had a very happy time, haven't you?”
“...!”
I understood immediately what Sakuna-san meant.
Sakuna-san watched me as my face turned bright red, looking amused, and pulled me into a tight hug just like during dinner.
She cradled my head gently, so I pressed my cheek against Sakuna-san’s breasts.
“I’m being way too spoiled today.”
“You’re still a child, Hayato-kun. Being spoiled is a child’s privilege.”
“...Even so, isn't it a bit much?”
“I don't mind at all. As I always say, I love it when you rely on me like this.”
I knew all of that was true.
Sakuna-san stroked my head and whispered into my ear.
“It’s late, and we won't be able to talk for very long. So why don't you let yourself be spoiled just a little more? Let’s continue from dinner.”
Coming at the end of a day like today, there was no way I could hold back when told something like that.
I sat down on the sofa with Sakuna-san and buried my face in her chest, while simultaneously wrapping my arms around her back and hugging her as if I didn't want to let go.
“Good boy, good boy. You’re such a good boy, Hayato-kun.”
“...Mom.”
“Yes♪”
Calling Sakuna-san "Mom"... it was becoming a habit.
After that, Sakuna-san continued to hold me, and I was given plenty of healing until I was satisfied.
“...Ahaha.”
“What is it?”
“No... it’s just that my sleepiness has completely vanished.”
“My, that’s a problem.”
“Well, tomorrow is a day off, so I don't mind at all.”
In the first place, if there was school tomorrow, I wouldn't have gone that far with Arisa and Aina... right?
“In that case, shall we talk a little more?”
“Is that okay?”
“Of course. Tomorrow is my day off too, and more than anything, I usually get more sleep than I need because I’m too serious. So, since I’m sharing this time with you, Hayato-kun, I thought I’d stay up a little late♪”
“...Then, will you please keep me company?”
“Yes♪ Well then, what shall we talk about?”
Sakuna-san leaned her face in close.
By linking her arm with mine as a lover would, her extra-large burst-sized breasts were squeezed and pressed against me. Sakuna-san naturally noticed that my heart was pounding because of it.
“You’re so cute, Hayato-kun.”
She whispered into my ear along with her breath, and my body temperature rose rapidly.
I knew it was wrong, but perhaps because I had just finished with Arisa and Aina, I was strongly conscious of Sakuna-san as a woman.
And then, I remembered the time I had kissed a half-asleep Sakuna-san.
“...A-Ah, um! Sakuna-san!”
“Y-Yes!”
“I want to see old photos of you, Sakuna-san!”
It was a desperate attempt to change the subject, but Sakuna-san had a blank expression.
I was aware I had said something out of the blue, but it was true that I was a little interested.
“Old photos, is it... please wait a moment.”
Ah, she’s okay with it... but if there are some, I want to see them!
Sakuna-san stood up, left the living room, and returned with a single photo in her hand.
“Well, I’m embarrassed too... so please let this be enough.”
“Ah, yes...”
“This is a photo from when I was a university student.”
The photo she tentatively handed me showed a young Sakuna-san with a smile on her face.
“...Ohh.”
To be honest, her features hadn't changed much... but it was incredibly fresh.
What had changed was mostly her hairstyle; her black hair was straight and long like Arisa’s, and she was wearing earrings.
So this was the young Sakuna-san.
Man, her breasts were huge even back then... if someone like this had been in the same classroom, the guys nearby must have had a tough time.
“You’re... beautiful.”
“Thank you...”
“And... I think you’re very cute.”
She was beautiful and cute... it was a cliché, but that was what I honestly thought.
“Ah...!”
However, it seemed that even Sakuna-san couldn't win against her embarrassment this time.
“Let’s go to sleep soon! As for the photos, I’ll show them to you again sometime!”
“Y-You’re right! Thank you very much!”
A blushing Sakuna-san... she really is incredibly cute.
I returned the photo to Sakuna-san, exchanged "good nights," and went back to Arisa’s room.
“I’m back.”
Neither of them had woken up, but their positions had changed significantly.
Aina was hugging Arisa as if burying her face in her chest, and the sight of the harmonious sisters was there.
“...I see, so this is the final birthday present.”
It seemed God had prepared a quite thoughtful present for the end.
The privilege of only me being allowed into this room and being able to see their naked bodies as their boyfriend... I captured the sight of the two of them in a photo with my smartphone.
“Now then, time to get some sleep.”
And so, my birthday came to an end.
Truly... it was a truly happy day.
Thank you Arisa, Aina, Sakuna-san... please, I want to keep having birthdays like this for years to come—that is my wish.
