"Is this not the basement where you keep beautiful girls imprisoned?"
"I am not, I have not, don't talk nonsense."
Facing Mashiro's question, Rin Ito immediately issued a triple denial.
While it was certainly meant to be a convenient location for parties, it was definitely not some dungeon for imprisoning girls!
"That's how they draw it in doujins," Mashiro stated flatly.
"Reality is not a doujin."
"..."
Mashiro remained silent, but she silently lowered her gaze toward Rin's crotch.
Her eyes seemed to say: That part of you doesn't look very realistic at all.
"Let's just go look at the basement then..."
Halfway through his sentence, Rin stopped.
He remembered that he had agreed to lend the basement to Moeha so she could store some of her "collections."
Could her movements really be that fast?
Could it be...
No way...
Is it possible...
Thinking of this, Rin paused and added a quick defensive line for himself.
"At most, there might be some reference materials for drawing manga. I'll take you on a tour."
With that, Rin led Mashiro to the basement stairs.
The staircase extending downward was like the maw of a dark abyss.
It looked as if countless tentacles would surge out at any second to pull passing maidens into a breeding ground.
Mashiro, like a brave knight, stepped onto the stairs and opened the basement door.
And then...
"See? It really is a basement for imprisoning girls."
Looking in the direction Mashiro was pointing, Rin's lip twitched.
Damn it, there actually is one.
Moeha had moved incredibly fast.
The basement was already filled with various training tools.
There was the X-frame rack they used on Rin earlier, a cage suitable for a large dog or a small human, a triangular wooden horse, and a chair with high leg rests.
There was even a C-shaped iron frame.
Chain-linked soft cuffs hung from the frame, designed to bind limbs into various positions.
As for why Rin knew how to use them so well...
Aside from seeing them in doujins, there was currently a "model" right in front of them demonstrating their use.
One had to admit, Chika's body was remarkably flexible.
Her hands were cuffed high above her head, exposing her smooth, hairless armpits.
Her right leg was hoisted up until her foot was nearly higher than her head.
With only her left foot on the ground for support, Chika was forced to expose every secret part of her body to Rin and Mashiro.
Of course, besides being cuffed, Chika had other accessories.
A ball gag was buckled into her mouth, firmly blocking her voice.
She could only let out muffled "mmm-mmm" sounds.
Drool leaked past the gag, sliding down her chin and following the line of her tensed thighs.
On her chest, two clamps were connected by a chain.
A small wooden sign hung from the middle of the chain, pulling her nipples downward.
The tension firmly locked the rich milk inside her, making Rin feel as though her breasts had swollen by a full size.
Chika didn't have any other toys on her.
Even though it was just the gag and clamps, Chika had a bit of a masochistic streak.
This level of "light" neglect play was within her range of acceptance.
In fact, she was so aroused that her juices were dripping down her thighs onto the floor.
Rin noticed some clean plastic bottles placed beside her.
He quietly closed the basement door.
Chika had clearly been tricked here by Moeha. Even Kei Shirogane probably didn't know.
After securing the door, Rin walked over to Chika.
Seeing him approach, Chika immediately began to make frantic muffled noises.
However, she didn't dare move too much; the wooden sign between her breasts would tug painfully if she swayed.
"Mmmph! Mmm-mmph!!!!"
Rin ignored her whimpers and her lust-filled eyes, picking up the small wooden sign on her chest to read it.
[Moeha's Gift for Big Brother~]
"Tricked into coming here by Moeha, weren't you?"
"Mmm-mmm!!!"
Chika nodded unhesitatingly.
But the movement caused her breasts to sway, and the resulting tug made her wince.
"Don't worry. I'll help you get revenge!"
"Mmm-mmm!!!!"
I'm not asking for revenge! I'm asking you to let me down! I've been clamped all day and can't get anything out! My chest is bursting!!!!
Unable to speak, Chika could only use her eyes for desperate hints.
But Rin remained unmoved.
Smiling, he patted Chika's shoulder but didn't remove the ball gag.
Instead, he took out his phone and messaged Moeha.
Rin: [I received the gift.]
Rin: [Come to the basement. I have a gift for you too.]
Rin: [Kei and the friends I brought are cleaning upstairs. Avoid them.]
Moeha: [Roger!]
Within a few minutes, Moeha from next door slipped inside.
Entering the basement, she immediately fixed a curious gaze on Mashiro.
Mashiro was about to speak, but Rin beat her to it.
"Moeha, let me introduce you. This is my pet, Mashiro."
"Hello, hello~ Big Brother's pet is so cute~"
The familiar Moeha stood on her tiptoes and gently ruffled Mashiro's hair.
Mashiro, having her line stolen, kicked Rin in the shin.
She had met Chika at Kaede's house before, but this was her first time meeting Moeha.
Given Moeha's reaction, Mashiro was a bit disappointed. She wanted to see shock, not casual acceptance.
"Does Kei know you turned this place into a dungeon?"
"Hehe, I finished setting this up before Kei moved in. She doesn't know yet~ These are all prepared for Kei and Kaguya-chan~"
"MMMPH!!!!"
If they are for them, why am I the one tied up!!!!
Rin ignored Chika's muffled protest and looked at the bottles at her feet.
Noticing his gaze, Moeha's face filled with mischief.
"Big Brother's studio is having a dinner today. Sis's flavor is so good, why not let everyone have a taste? I've been putting what I squeezed out of her in the fridge these past few days."
Hearing Moeha, Chika's whimpering grew louder.
But both of them ignored her. Mashiro simply leaned in and poked Chika's swollen, white breasts with her finger.
"No problem," Rin agreed readily, then shifted his tone.
"If Chika can secrete milk without being pregnant, maybe you can too, Moeha. You are sisters, after all."
"Impossible. Mine are so small, how could there be baby food in here?"
Moeha blinked and smirked.
"Is Big Brother just looking for an excuse to rub my chest~? Oh dear, you don't have to be so indirect~"
"You caught me."
Seeing Rin admit it, Moeha unhesitatingly pulled off her t-shirt.
Wearing no bra, she brazenly displayed her small, perky breasts to Rin.
They weren't small for her age—actually larger than the unpadded versions of Hayasaka or Kaguya—but they were humble compared to Chika's.
Rin moved behind Moeha and pulled her into a hug, his fingers beginning to knead and massage her chest.
"Sisters share genes. Maybe I really can knead some baby food out of you. It has nothing to do with size; even flat chests can produce it," Rin whispered wickedly into Moeha's ear.
However, his words were actually meant for Kaede, who he knew was watching through the system.
"Uuu... Big Brother's technique is so practiced. I don't feel any baby food, but it feels like my 'baby's room' is about to open up~"
Under his expert touch, Moeha's body quickly went limp.
"If Big Brother wants me to be like Sis... then get me pregnant~"
"In your dreams!"
"Ehehe~" Moeha stuck her tongue out after Rin tapped her head.
Under Rin's skilled hands, Moeha's knees soon pressed together tightly as she tried to hold back the surging tide within her.
Moeha had climaxed before, but this time she felt a hot current in her chest in addition to her abdomen...
She had no capacity left to think.
The moment Moeha's body tensed, Rin squeezed her breasts firmly.
And then...
Squirt!
A stream of milk arched gracefully through the air in front of Moeha's eyes.
"As expected of sisters... Chika started secreting while she was still a virgin too."
"...?"
Moeha looked down, stunned, at her own milk-scented chest.
Wait... I'm actually just like Sis?
While Moeha was in a daze... Click!
A crisp metallic sound rang out.
Snapping back to reality, Moeha found her own hands cuffed to the iron frame.
"B-Big Brother? Wait... Big Brother!!!"
It wasn't just her hands.
Under Moeha's shocked gaze, Rin hoisted her left leg over her head and cuffed her ankle.
The sisters were now positioned together—one with her left leg up, the other with her right.
Moeha started to panic.
Weren't the three of us supposed to toy with Sis together? Why am I being locked up too!
"Ah~ Open up~"
Rin pulled a ball gag from the toy box and stuffed it into Moeha's mouth.
Then he removed the clamp from Chika's left breast and, after a little tug, snapped it onto Moeha's left nipple.
"Ahem... The Fujiwaras might not have tofu, but you have milk. Since you two want to contribute to the dinner so badly, I won't be polite."
Rin paused and looked at Mashiro, winking.
"By the way, I haven't told you. The Fujiwaras are a political dynasty. Chika or Moeha might even be a female Prime Minister one day. Mashiro, why don't you paint a picture of them working hard for this dinner? We can auction it off later to fund their campaigns."
"We'll call it... The Fujiwara Sisters Milking Diagram. How about it?"
"No problem!"
Mashiro gave a serious thumbs-up.
She then assumed a pose of intense observation, staring back and forth between Moeha and Chika.
"I don't have a brush right now, but Mashiro is a genius who can remember every single detail."
"MMMPH!!!! MMM-MMMM!!!!"
Hearing this, Chika shook her head frantically, tears of desperation leaking from her eyes.
Moeha, on the other hand, just looked confused.
"Moeha, let me introduce her properly. Mashiro's full name is Mashiro Shiina. You should have heard that name before, right?"
"!!!!"
Moeha didn't know much about oil painting, but as a daughter of the Fujiwara family, she had heard of the prodigy.
The genius artist Mashiro Shiina is actually Big Brother's pet!
An image flashed in Moeha's mind: Chika running for Prime Minister while her supporters waved copies of The Fujiwara Sisters Milking Diagram to cheer her on.
Then, after Chika won, the value of the painting would skyrocket.
Global news would report that the genius Mashiro Shiina painted the female Prime Minister being milked. The image would travel across the world.
While Moeha knew Rin was joking and wouldn't actually let Mashiro sell it, the thought itself was hilarious.
The painting was a joke, but the milking for their guests was not!
Faced with Rin holding a cup to her chest, Moeha was as helpless as Chika.
Bound by her hands and one leg, she could only endure as Rin squeezed her cup full, bit by bit.
"Mmm~ Such a fragrant scent."
After filling a cup for Moeha, Rin moved to Chika.
Chika had been clamped so long that she was swollen to the bursting point.
One squeeze from Rin and she overflowed.
Once he had both cups full, Rin took a sip from Moeha on the left and Chika on the right. It was incredibly erotic.
"Mmm~~~~ Chika is rich and mellow, while Moeha is light and sweet. The Fujiwaras don't have tofu, but the milk is first class!"
