That night, after dinner, I was in the underground training room before my bath. I stood vertically on the wall, merging my qi with it—a basic Renkan Keikikou exercise, now just a light stretch for me.
Why was I here alone? My new potential was nagging at me. No overdoing it, just focusing my mind, diving into my Sacred Gear to face that mysterious domain. No progress, sadly, but it clears my head.
"Overthinking leads to spinning wheels. Reset your mind sometimes," Ignis said.
True. I'll do this a few times a week, even if irregularly.
Ten minutes in, the door opened. "Not in your room? Knew you'd be here," Rias said, holding clothes and a towel, likely heading to the bath.
I stopped, jumping down. "Training?"
"More like mental focus. My training's stalled, so I'm clearing my head," I said.
"Don't overdo it. You're strong enough," Rias said.
"I know, no rushing," I grinned.
She smiled back. Do others see me as overdoing it? I plan my training with health in mind…
Noticing my clothes, Rias asked, "No bath yet?"
"Nope, after this. You?"
"Yes."
"Go ahead. I'll wait," I said, turning to resume.
She grabbed my hand. "Issei, let's bathe together. It's lonely in that big bath alone."
Bath invite!? Seeing Rias's stunning body up close? Is that okay!? We've bathed together before, but still! It's Rias's invitation—I can't refuse!
So, we headed to the bath.
"Paradise!" I sighed, soaking in the underground bath.
The day's fatigue melted away. The Hyoudou residence's massive bath, built during summer renovations, fits twenty easily. There's a normal-sized bath upstairs, but the girls here wash together, a heartwarming sight. I join sometimes. Dad uses the upstairs bath, per Mom's orders, for the girls' sake. He's cool with it.
Now, just Rias and I soaked in the vast bath.
"Washing your back felt nice. So sturdy," Rias said, blushing slightly.
Yes! A beauty scrubbed my back! Perfect scenario! Mixed bathing rules!
"Been a while since we bathed alone. Since I moved in?" Rias asked.
"Probably. Miu and Asia were around then," I said.
We bathed with them a few times in the old, cramped bath. No complaints—beautiful girls! But just Rias and me? Rare.
Rias giggled. "What?"
"Bathing alone feels like lovers. Sorry to Miu, though…"
Lovers, huh. Since Miu and I got together, I haven't had much one-on-one time with others. The girls come in groups, their affection amped up, overwhelming me. I wondered if Miu would mind me getting close to others, but when I asked…
"Your dream's a harem king, right? I'm fine with you being close to everyone. You can make them happy. Just let me be spoiled sometimes," she'd said, smiling.
Miu felt… grown-up somehow. Still clingy, though—she loved my lap and head pats recently.
I chuckled. "Miu doesn't mind."
"She's younger, but feels more mature than me. My imagination?" Rias asked.
"Not imagination," I laughed.
"Her confidence as the main wife?" Rias mused.
I just laughed awkwardly.
Oh, right! "Rias, you seem troubled lately."
"Huh?"
"Since Venerana-san came to the Oppai Dragon show, you've been off sometimes. Something up?"
At the show, Venerana and Millicas attended. Venerana wanted to talk to Rias alone, so I left with Millicas. Since then, Rias has been… odd. Sometimes not responding when called.
She blushed, eyes down. Bad topic?
Softly, she said, "Issei, I have two requests."
"Requests?" I echoed.
She nodded, nervous. Important, maybe?
"We've never gone out alone, right?" she said.
True, she mentioned that before. Venerana seemed exasperated then.
"After the game… will you go on a date with me?" she asked, blushing, fidgeting.
Adorable! Where's the confident big sister? She's all maidenly!
My answer's obvious. "Of course! I'd never refuse you!"
I gave a thumbs-up. A date with Rias? Hell yeah!
She beamed, hugging me. "Thank you, Issei!"
Her ample chest and thighs pressed against me. Heavenly!
A date after the game, plus the festival? Can't wait!
First request: a date. So cute!
"What's the second?" I asked.
Rias trembled, her face redder than ever. She looked down, then up, and—
"Will you… press my chest?"
…What?
Hallucination? Did she say that?
No way. I'm tired from training. "Sorry, I misheard. Again?"
"…Please press my chest," she repeated.
Not a mistake! What!?
"Explain!" My brain can't process this!
Rias explained.
At the hero show, after I left with Millicas, Venerana told Rias, "Miu confessed bravely, taking the lead. Alice offered her chest, helping him reach Balance Breaker. They stand out among the women around him."
"I know," Rias had replied. "They're special to him, more than us latecomers."
"Then become special," Venerana said. "You're just Switch Princess in the show. If that bothers you, become the real Switch Princess."
This is insane! I get it until the Switch Princess part! Why that!?
"Venerana said that, and I didn't know what to do. I was troubled," Rias said.
Of course! Going from a show role to real life is wild! Why, Venerana!?
"So… you want me to press your chest?" I asked.
"Yes. Like with Alice, maybe it'll change something. It's weird, right?" she said.
Super weird! Why'd you take it seriously!?
But Rias stood, resolute. "I've decided! You'll press my chest! To be special to you, I'll be the real Switch Princess!"
Rias!? Why this determination!? The press conference mess—reporters grilling her—fueled this!?
Her swaying chest caught my eye. What a sight! Eye candy!
She sat before me, offering her chest. "Do it! Press my chest!"
Is this really Rias!? Her character's breaking!
No more thinking, Issei. Focus on the chest!
I aimed my index finger at her nipple. "Here I go…"
"Anytime," she said.
Swallowing hard, I moved—
Crash!
A noise! We turned. Alice stood at the door, towel dropped.
"Issei!? Rias-san!? What's going on!?"
"Seriously!?" Alice's voice echoed.
Caught, we sat seiza before her, explaining everything. In the bath.
Alice was stunned. No girl volunteers to be Switch Princess, right?
But Rias, serious, said, "I'm serious. If I become a real Switch Princess, I can help Issei's issue."
"How?" Alice asked, skeptical.
"Issei reached Balance Breaker via your chest. If I'm a real Switch Princess, it might advance his training," Rias said.
"I'm really Switch Princess…" Alice sighed.
She's the original. Can't help it.
Rias thinks her chest could push my next stage. Possible, but… iffy.
"You gonna press? Power up via girls' chests again?" Alice asked.
"Maybe. Not sure about powering up, but I'll try," I said.
Alice sighed. "I can't unsee you powering up that way…"
Sorry. But it worked once, so… maybe?
Then, Alice steeled herself. "Issei, press mine too."
"What!?"
"I can't let Rias bear this embarrassment alone. I started this Switch Princess mess. Plus, two might boost your odds," she said, sitting beside Rias, removing her towel, bare like Rias.
Two at once!?
"Hurry!" Alice's voice cracked.
Is this okay!? Won't I get roasted or stabbed like last time!?
"I'm ready," Rias said, offering her chest again.
Rias and Alice's chests at once!? I'm moved! My fists tremble!
Breathing deep, I aimed—left for Alice, right for Rias. Locked on their pink nipples.
"Here I go!" My fingers hit—Rias's sank deep, Alice's firm.
"Eek!" Rias gasped.
"Ahh!" Alice moaned.
That moment flashed back—when I pressed Alice's chest, reaching Balance Breaker.
Flash!
Red light flooded the bath, radiating from their chests.
"What's this!?" I exclaimed.
"Our chests… glowing!?" Rias said.
Their breasts shone divinely, warmly.
Thump!
Something pulsed within me.
"This was the key," Ignis said.
Key?
"Listen, Issei. Your potential's stirring!" she said.
Really!?
"Slightly, but it's moving. Despite all your training, their glowing chests triggered it!" Ignis said, hyped.
Ouch, my training did nothing!? And why's she so excited!?
Rias and Alice heard. "Really…?" Rias gasped.
"Why's it always chests with you!?" Alice cried, teary.
Sorry! I'm truly Oppai Dragon! Breaking limits via chests! The show's real now!
"Alice Audelia, Rias Gremory, you're true Switch Princesses! Be proud—your breasts opened the door to his next stage!" Ignis declared.
"Issei, I did it! I'm a real Switch Princess!" Rias said.
"Issei, take responsibility, or else!" Alice warned.
On this day, before the dream-driven game, two Switch Princesses were born. One, my master and senior; the other, my interdimensional comrade. Rias transcended her show role; Alice solidified her place with a second press.
White Lightning Switch Princess, Alice Audelia.
Crimson-Haired Switch Princess, Rias Gremory.
And Ddraig wept.
