 ------------------------------------------------------------------------------------------------------------------------
The Japanese-style hot spring existed in an isolated corner of the Gremory's garden.
I immediately immersed myself in it completely along with Kiba and Azazel-sensei. Ah, I'm healing. This is a good hot spring.
"When going on a trip~♪"
While submerging himself into the hot spring, Azazel-sensei hummed a tune. Ooh, he'd also let out his twelve black wings.
"Hahahaha, as expected, when speaking of the Underworld—of hell, it's the hot springs. Moreover, when it comes to the distinguished Gremory family's private hot spring, one of the best in the Underworld, a great spring is also a great spring."
Surprisingly, the Governor-sama seemed accustomed to hot springs. That's right, he was wearing a yukata when I met him for the first time. Could it be that he really likes Japanese culture?
Kiba and me had matching towels on our heads and had submerged ourselves in the hot water.
Since earlier, Kiba was being incredibly disgusting. Because he suddenly—.
"Ise-kun, shall I wash your back?"
What kind of thing are you saying while blushing? It's like my chastity is being stolen by you!
…Well, I suppose it's a precious thing, having some nude socialisation with a male—with a friend like him. Since we didn't get to open up to each other at the previous training camp, there was a restrained part between us.
…Now that I think about it, where is Gya-suke? Even if he's a cross-dressing boy, is he really unable to do some nude socialisation?
Ah. As expected, he's loitering at the entrance. Rather, it was inevitable!
I rose out of the hot water and headed over to Gasper.
"Hey, hey, come on, you have to enter since it's a hot spring."
I caught Gasper at the entrance.
"Kyah!"
Gasper screamed out in a cute manner.
"Kyah"…You really…Wait, don't roll up your towel all the way up to your chest…You aren't a girl……Damn it! He looked like a girl! He had a thin body and a girlish face! Why are you a man when you're like this!?
Because I was staring and scrutinising Gasper, he blushed and spoke.
"…U-Umm, please don't look at me like that…"
"…Y-You! Don't put up your towel all the way to your chest if you're a guy! Because you always dress like a girl, it's confusing for me as well!"
"…N-No way, you were looking at me like that, Ise-senpai…? I feel like my body is in dangeeeeeeeer!"
"Shut up!"
I had felt that I could go to the Underworld if things were just as is! Yet, I snatched this guy in a princess carry, and immediately brought him over to the hot springs—.
Spla——sh!
I threw him in.
"Nooooooooo! It's hoooooot! I'm meltiiiiiiing! Ise-senpai is perverteeeeeeed!"
His screaming echoed throughout the male baths! Idiot! Buchou and the others have already entered the female baths next to us!
[Ise, you can't sexually harass Gasper, you know?]
Buchou's teasing voice! After that, I heard the girls' small giggling! Waaaaaaaaah! So embarrassing!
I couldn't take it and plunged into the hot spring! Even after my head sunk down, I rose up immediately!
Uu, even though I just put the hikikomori into the hot spring…
"By the way, Ise."
Coming next to the watery-eyed me, Sensei had a lewd face.
"Yes?"
"Have you rubbed Rias' breasts?"
Sensei asked that while squeezing the fingers of both of his hands in the air.
"Y-Yes! With my right hand!"
I also gestured with my right hand in the air! Buchou's breasts had the best sensation! I think it's something I won't ever forget in my life! I feel like I could live with just that!
"I see. Then, how about—"
Nodding, Sensei made an "o" with his mouth and moved them, as if he was trying to catch something with them and spoke.
"Have you suck a woman's nipple with your mouth?"
Sensei moved his mouth again as if he was sucking something.
"—! …N-No, not yet."
Seeing my reaction, Sensei sighed.
"What's with you? You haven't sucked nipples with your mouth? Sucking breasts is amazing. No matter what their shape, no matter if they are big or small, no matter if they belong to a young girl or a mature woman, sucking them, feeling their nipples in the mouth is something you never forget, you know?"
Wh……at……? S-S-S-Sucking the breasts…? S-Sucking Buchou's breasts has always been my goal and dream…. I've finally touched them, so I should climb to the next level!
In the case of huge breasts, I'm certainly interested in sucking them!
"Yes! I want to suck them! I want nothing more than suck a Buchou oppai!!!"
That's right! Buchou's breasts are amazing and I always want to suck them! Rather, the instant when Buchou's breasts emerge, my love towards Buchou is wholehearted!
Sensei nodded his head at my words and grinned.
"Good attitude, Ise! And you know, there's something else. If you suck your breasts properly and the girl is sensitive enough, she'll make a sound [Hyaaan] and achieve it."
—!?
I imagined Buchou sounding [Hyaaan] because of me….
…What is this…T-There was such a world out there? But what is the „it" that Sensei mentioned.
"Breasts and nipples have a lot function… They can be sucked, licked, rubbed, cuddled in the face or you can even put something between them.... And then the girl will make sounds and maybe even achieve something…"
When I thought about it, I had never thought about oppai in that way. Why didn't I ever realise this wisdom?
While I was absorbed in my rubbing and my sucking-impulse, I definitely forgot about girls reactions and feelings!
—I'm so foolish!
Sensei patted my head.
"That's why you still have some way to go. A woman's breasts are infinite. Handled correctly, they are packed full of infinite possibilities more than the Ouroboros Ophis, you know? Because I was fascinated with them, I plunged into the breasts of women and fell. I don't regret it."
—As I thought, this person is amazing. You understand too, Governor!
While tears flowed down my cheeks, I spoke to Sensei with a trembling voice.
"Sensei— I want to suck breasts…"
Sensei gave me words of encouragement while gently patting my head.
"Yeah, don't give up, Ise. If it's you, you can do it. If you give up, that will be the end of breasts, right?"
"Yes. Yes!"
That's right. By not giving up, everything can also advance forward! By not giving up, Buchou's breasts can also be sucked! And I'll make Buchou cry out! Buchou will cry out to my sucking!
While I was like this, the voices of the girls reached my ears.
[Ara, Rias. Did your bust get bigger again? You like being groped by me, don't you?]
[R-Really? Umm…Your way of touching is a little indecent. Rather, didn't your bra cup change more than mine, Akeno?]
[My old one was still fine even though it was a bit tight…However, recently, I've been thinking that it wouldn't be bad to show it off in a bigger way. A woman becomes bolder when she has a partner she'd like to show it to, Rias.]
[…T-That's true. However, please don't stimulate that child so much.]
[I'm envious of how big you two are…]
[Ara-ara, Asia-chan. Haven't yours also gotten bigger than before?]
[I-Is that so…? B-But, if they're only this big…I can't seem to be able to come to like it.]
[Asia, did you hear the talk of how they become bigger if you rub them? Like this—]
[Haan! D-Don't! Xenovia-san! Ah…Uuun…Ise-san still hasn't done this kind of thing to me…]
[Hmm, Asia is different from me and has a good touching sensation. I see. This may be what delights me.

[Ara-ara, it's good to be young, isn't it, Rias? By the way, based on this feeling, you really have been getting bigger every day, haven't you?]
[Aan…A-Akeno, cut it out, release your hands from my breasts. The movements of your hands are—Aaaun! Where did you learn such a thing…?]
[Rias' breasts…What a nice sensation…Ufufu. I'll do this here and…]
[No…Aaaun, even though I haven't made that child do this kind of thing yet…S-Stop it…I decided that that child would be my first…Aaann…]
……
Listening to the conversation of the girls in the women's bath next door, I—was becoming aroused. My nosebleed wouldn't stop! Ah, this is bad, this is bad. I hit the back of my head with a smack and somehow held down my nosebleed.
Rather, what a conversation for them all to be having…I was reacting in various places…
But, I want to peek! I want to peek! Over the wall that separates the men's and women's baths! I'd like to go over it and fly down to that world there! Damn it! Isn't there a peeking hole? I couldn't see it anywhere no matter where I looked since before…
Rather, should I try using my Sacred Gear to strengthen my finger and make a hole…?
"What's with you? You want to peek?"
Azazel-sensei asked me that with a dirty smile.
"That's not so bad. It's a thing between men. It's a rule to peek at the women's bath while in the hot spring. —However, that just makes you a second-rate pervert."
"Second-rate!? T-Then, what do you do if you're first-rate!?"
Sensei looked like he was considering for a moment.
"…That's right. Like this!"
Yank! Sensei grabbed my arm. And then—.
"It's feeling! If you're man, it has to be mixed bathing, Ise!"
Buuuuuuuuuuuuuuuuuuuh! I was seized by a floating sensation and my field of vision moved dizzinglyyyyyyyyyy!
Owaaaaaaaaaah! I was blown off into the aaaaaaaaaaaair!
My field of vision moved from the men's bath to the bath next door and—. My eyes met Buchou's while in the air! And so then—.
Doppooooooooon!
……Oww. I hit the surface of the hot spring water hard, and floundered in the water!
Splash! When I jumped out from the hot water—paradise on Earth was there before me!
Buchou! Akeno-san! Asia! Xenovia! Koneko-chan! Everyone was naked!
Buh!
A nosebleed gushed out! Naturally! When suddenly being transported from a place of just stupid men to a world of only women, it's only natural for the world to change!
The mixed bathing that I had always dreamed about! My tears wouldn't stoooooop!
Normally, in this kind of situation, things like buckets would be flying with screams of "Kyaah! Pervert!", and I would be torn apart, but—.
Buchou, Akeno, Asia, and Xenovia didn't even try to hide their naked bodies! C-Cover yourselves, everyone! You're girls, after all!
"Ara, Ise. Were you thrown over by Azazel? Was your body properly washed?"
"Ufufu, oh Ise-kun. You're so daring."
Rather, Buchou and Akeno-san were coming closer while smiling wryly! Their big white breasts were swaying up and down right in front of me! Hurray for breasts!
I was at my wit's end and transfixed by the breasts that were approaching me. Akeno-san caught me an instant before Buchou did!
"Ise-kun♪ I caught you."
Squish.
She embraced me from the front, and Akeno-san's body became glued to my body! Let alone her breasts! Everything! All of Akeno's soft body was on meeeeeeeeee!
"A-Akeno-san! I-I-I-I-If you cling to me like that!"
My brain was affected by both the heat of the hot springs and the erotic heat, and my head was on the verge of boiling! Aaah, damn it! Akeno's body really is incredible! Why does her body feel so good!? Both its springiness and elasticity are amazing! Was this increased smooth feeling the effect of the hot spring!?
Squish!
Although I had been satisfied with Akeno-san's whole body, I was once again hit by some first-rate softness!
Buchou's face popped out over my shoulder! B-Buchou! This time it was Buchou clinging to me from behiiiiiiiiiiind!?
The sensation of Buchou's breasts hit me from behind! Aah, the tips of those things were stimulating my back! I think Buchou's nipples were more effective at soothing than a poor massage machine!
"Akeno! Get away from my Ise!"
Buchou wrapped her arms around my neck and tried to snatch me away from Akeno-san! However, Akeno-san was firmly clinging to me from my front!
"No way. I've decided to enjoy the hot springs with Ise-kun. I'm already heating up our bodies by clinging like this…Ise-kun's body feels good just by touching it like this…"
Akeno-san clung to me even more firmly! Uwaaaaaah, Akeno-san's breasts are being pressed so much that it's like they'll fuse with my body! Amaziiiiiiiing! This deadly softness! I also wanted to embrace Akeno-san's body against my better judgment! But, if I did that, Buchou will get angry at her servant's betrayal and kill me!
"Stop it! Ise's body is mine! Who do you think trained and raised this child!? It's the fruits of my labor that made the sensation of embracing him like this the best! From this child's hair to his entire body, everything is mine! —Aah. Somehow, I'm feeling sensitive. Is this because of what Akeno-san did just before…or is it because I'm touching Ise…?"
Buchou's embrace also became stronger! Uwaaaaah! Onee-sama's breasts were being perfectly transmitted even from my back! The volume was like an extra-large all-you-can-eat buffet! Moreover, I could even hear her rough breathing! Buchou's sexy voice was destroying my brain!
I mean, I was raised by Buchou!? So the finishing condition on this body of mine was also for the sake of being used as Buchou's hugging pillow!? I'm happy! Please give me more sexual training and nurturing!
A-Akeno-san's breasts were touching my chest, and B-Buchou's breasts were touching my back!
I was caught between Buchou's breasts and Akeno-san's breasts from the front and baaaaaaaack!
Amaziiiiiiiiiiing! I was caught between breeeeeeeeeeeeasts!
[This is the legendary breast sandwich! A paradise exists in the unexplored regions of the Underworld!]
A voice like that from a survival program rushed through my mind!
With such stimulus from the breasts sandwich, I, in a pleasant dream space, couldn't help but discharge a stream of nosebleed…
…Sensei had talked about it. If it's now, when I'm caught between them, I can poke! If I poke like with a front-door buzzer, Buchou may let out an [Hyaaan]. Amazing! The female body is amazing!
My finger was being buried in the nipple! What on earth was happening!? Was my finger being eaten up by Buchou's breasts!?
"Auu, even though I want to enjoy the hot springs with Ise-san too…"
"As I thought, it'll be an almost impossible task to snatch Ise away from those two. I have no choice but to watch from afar for today."
Asia and Xenovia were talking about something from a little further away, but…the impact of the breast sandwich was too strong…
Hah! Suddenly, I came to my senses! Based on this situation, Koneko-chan would be muttering "…Disgusting. Pervert-senpai.", and would blow me away somewhere with an especially large punch!
I timidly turned my gaze to look at Koneko-chan, but—.
Koneko-chan had half-submerged her face in the hot springs while wearing a gloomy-looking expression, and was blowing bubbles in the water…Huh? Is Koneko-chan still not feeling good…? Then…..
"Kyaaa!"
"Ara!"
I slipped and fell with both girls! Now I was sitting between them and my head was hugged between their breasts! They were so soft, tender and flexible! This is a breast sandwich now! Buchou and Akeno-san giggled and kept pushing me with their oppai!!! What an amazing feeling! Hmm, wait, maybe now I could try... I managed to turn my head so that now Buchou was in front of me. Mmmm, her wonderful breasts never get tired of me, they're so soft.
"Ufufufu, Ise, I can see that you want to hug your face in my oppai. Please, do whatever you want. See, Akeno, I told you Ise prefers mine."
"That's impossible. I have bigger breasts than you, so Ise should prefer mine."
"But She prefer mine!"
"No! Mine!"
It was an amazing situation! Both girls were squeezing my head between their breasts more and more, and I was so happy, but at the same time I felt that from the excitement, a blood geyser would shoot out of my nose, I suddenly remembered what Azazel-sensei told me. So I couldn't waste any time and had to act. I decided to take advantage of the fact that my face was clasped in Buchou's breast. I opened my mouth and tried to grab her nipple, which was literally an inch from me, but suddenly at that moment, my consciousness began to recede.
Yeah, I understand. With the blood streaming down from my nose, I was losing myself in the heat from both the hot springs and the breast sandwich…
"…Nuhahhoh."
…I got the sensation that my soul was escaping from my mouth. Even getting too happy makes my soul fall out…
"Ise-kun!"
"Ise!"
Akeno-san and Buchou were making a panicked commotion. But, I was happy… just happy.
Matsuda, Motohama, there is definitely paradise in hell. Is this what it means for a Buddha to be in hell?
Next time, I'll tell you of the wonderfulness of the breast sandwich…
And so in this way, I lost consciousness.

[…]
Koneko-chan smiled even though she was in pain from the poison. It was a dazzling smile.
"Please become a gentle [Welsh Dragon]…"
Koneko-chan…I…
After hearing Koneko-chan's words, I felt like I understood something inside me.
"—Buchou. I think I understand a little what I was lacking in myself to attain Balance Breaker."
Yes, I felt that I saw the true meaning in Koneko-chan's words just now.
"I'm probably going to need Buchou's power in order to attain Balance Breaker."
I will attain it by borrowing Buchou's power—.
"…I understand! If you're fine with me, I'll lend you my power! So, what do I need to do?"
Buchou nodded even though she was in pain from the poison. I made up my mind, took a big gulp, and spoke.
"—Please let me suck your breasts!"
"—!"
At my request, Buchou—became speechless. However, after thinking a little, she spoke with a look of determination.
"…I understand. If I can realise your wish with that…"
—!? …I was bewildered by her ready consent! Impossible! Is such a thing possible!? It's no joke! Buchou, I really do want to suck your nipples!
"R-Really!? I can suck them!? I can really suck on Buchou's nipples with my mouth!? It's really okay!?"
Burun!
Buchou pulled down her dress and exposed her bared front with trembling hands, summoning her great jugs! Because the thing that restrained them was gone, her abundant breasts jiggled!
Bubah! To this pure undressing, I could only spurt out a nosebleed in reaction!
"…Please do it quickly. I-It's embarrassing…"
Buchou was turning both pale from the poison and red from embarrassment! I'm sorry, Buchou! I didn't think it would possibly turn out like this!
"H-Hey! What are you doing in the middle of a battlefield!?"
From high above the thin mist, Tannin-ossan gave out an astonished shout.
"Ossan! Please support me while I suck Buchou's nipples!"
"Suck her nipples!? Suck her nipples, you say!? What are you saying!? What are you trying to do in the middle of a battlefield!?"
"If I suck them, the possibility that I will attain Balance Breaker is high!"
"So the training with me was a waste!? You truly are an idiot!"
At that time, Koneko-chan's onee-san gave a puzzled expression.
"Hey, Bikou! Is that some kind of strategy? Rias Gremory has revealed her breasts and intends to do something with the Sekiryuutei."
"Don't ask me! The thought process of the Sekiryuutei is in a different dimension from us, you know!"
What a rude monkey! I'm serious here! I think that I have no choice but to suck Buchou's nipples in order to attain Balance Breaker!
The talk I had with Sensei had a dramatic impact on me. The dramatic change I first thought of after the conversation with Koneko-chan is—to suck breasts.
Because! After Sensei told me about it, that was the only thing that filled my brain, and I had wild delusions all this time about just sucking them! If I suck them, I should be able to change!
—. Having Buchou's breasts immediately in front of me, I wavered… Oh no. This is bad.
"O-Ossan! I have a serious problem!"
"What's wrong!? What is it!?"
I thought that it was better to ask the former-Dragon King here!
"The right breast or the left breast! Which should I suck first!?"
"You damn idioooooooot! Right or left, it's the same thing! Just suck them already and attain Balance Breakeeeeeeeeeer!"
"Don't joke around! Right and left aren't the same thiiiiiiiiiiiing! It's important! It's my first time to suck breasts! It's a once in a lifetime thing! Answer seriouslyyyyyyyyyyyyy!"
For some reason, me and Ossan were quarrelling! Damn it! Ossan doesn't understand! Which breast I suck is an important matter!
"Buchou! What's your recommendation!?"
If it's like this, I'll ask the person herself!
"Geez! You idiot! In that case, if it was possible, you should just suck them both at the same time!"
"—!?"
What a ground-breaking idea! I shed tears at my master's answer!
I aimed both my hands at each of Buchou's breasts. This is fine. With this, I won't miss. The five fingers in both my hands get absorbed by her enormous breasts. Ahhh!! They were so soft! They never get tired of me! But this is no time for such thoughts! Now I have to act!
My body was in very bad shape from the damage delivered by Koneko-chan's onee-san, but this situation where I can suck breasts gave me unbelievable energy!
Then, after gulping, I suddenly squeezed Buchou's breasts together so that the nipples came into contact with each other!
"Ise, what are you...!?"
Before Buchou finished talking, I took both her nipples in my mouth and started sucking!
Munyun.
Munyu, munyu, munyuuuuuu.
They were amazing! The touch of skin on my lips, those nipples inside my mouth! And they tasted so... so... I don't know how to describe it, they were just great! I tried to grab as much of her breasts into my mouth as possible and while sucking, I licked her areolas. Mmmmmmm. I felt her nipples hardening in my mouth! How incredible. Suddenly Buchou embraced my head with her hands and pressed to her breasts. Wow! Her face was so red and she breathed very deeply! Ah she even rubbed her thighs! It must have been very nice for her! Maybe her breasts are her weak point!? That's good to know! Maybe I can use that knowledge in the future??
"Ah…..Ise…...if you…..dont stop…...I….I…...ah…..!!!!"
Hmm? Something happened to her? Maybe I should try something new? Suddenly something came to my mind. I gently bit my teeth both her nipples at once!
"Hyaaaaaaaaaaaaaaaan!!!!"
Buchou screamed very loudly and after that fell to the ground, and her nipples slipped out of my mouth with a loud clap. Now she knelt on the ground and breathed deeply. She had her eyes closed and her face very red. But the best view was of her breasts. Her nipples were as hard as ever and now they stood up fiercely and they were also red from my caresses and wet from my saliva! Suddenly Buchou opened her eyes slightly.
"Ise... I... I... I think I came....."
When I heard that, inside me, something revolutionary burst open—.
It spread. Something vast—took over my mind.
Within the tears that wouldn't stop, I saw it.

—The beginning of the universe.

[—You attained it. You really managed to attain it!]
Ddraig laughed inside me and let out an innocent cry.
[Welsh Dragon Balance Breaker!!!!!!!!!]
The light returned to the jewel, and on the contrary began to emit a huge mass of red aura that it didn't have until now! The aura wrapped around my entire body!
"…You're the worst. What a lewd Sekiryuutei…"
