Rin Ito used Mutsumi as leverage, making it impossible for Sakiko to refuse.
Because the truth was exactly that—back at the hotel, she had blacked out instantly from the overwhelming stimulation and shame. By the time she woke up, Mutsumi was already gone.
It was exactly as Rin said: she couldn't satisfy Mutsumi if she just kept fainting.
However...
"Endurance training... why does endurance training require so many people?"
"Ahem." Rin cleared his throat, putting on a facade of absolute seriousness. "Your adaptability is too low. If I do it, you'll just pass out like last time. These girls are gentler; they can slowly apply stimulation to let your body adjust."
Rin was talking total nonsense. As Sakiko noted, even for "training," this many people were unnecessary. The real purpose of this party was to deepen their bonds in preparation for the "Dark Hand" that would eventually dominate the world.
Rin's excuse was barely passing.
Sakiko's slender fingers unconsciously twisted the hem of her shirt. She knew she was being talked into it. Or rather, she needed this excuse to convince herself, otherwise her high Ojou-sama pride would never let her accept this calmly.
Regardless of how ridiculous Rin's logic was, as long as she had an excuse, she could trick her own mind. But doing something like this in front of so many girls she had only met a few times still made her die of embarrassment.
At this moment, Mashiro's famous logic came into play.
"Still shy? It's fine. If everyone strips together, the shame disappears!"
Rin convinced Sakiko. Once Sakiko's pride was sufficiently bribed, she bit her lip and suppressed her nerves, shedding her clothes.
Chika and the others were a bit shy too, but as veterans of these parties, they didn't hesitate for a second.
Karen and Shion, Kaguya and Ai, Chika and Moeha, and Sakiko herself. In an instant, the cold basement was painted in the warm hues of seven blushing maidens, accompanied by a faint, sweet scent of milk.
Sakiko smelled it but assumed it was just their milky body wash and didn't give it much thought. She followed Rin to the chair that looked like a gynecological exam table and sat down according to his instructions.
"Lean back on this chair. Put your hands on the armrests and spread your legs wide across the rests. Don't be shy; they are all girls, and I've already seen everything... that's it, just like that."
The seat was soft, and leaning back felt much like lying in a bed. The armrests and footrests were padded, so nothing felt hard against her skin. The only issue was the pose—it was utterly mortifying. Having her legs spread wide on the rests exposed every single secret of her junction to the cool air.
Her rear, which was twitching like a rhythmic breath due to her nerves, was also fully exposed. Her ten toes curled tight in embarrassment, and with her hands cuffed, even her scarlet face was a target for everyone to admire.
"EH!?"
Sakiko suddenly realized her limbs were being locked into the chair. While she had a small range of motion, she couldn't sit up. Her only possible movement was clenching her fists.
"This is to keep you from running away. If it hurts, tell Moeha; she'll adjust the cuffs for you." As Rin spoke, he carefully checked the stability of the restraints. Once he was sure Sakiko was trapped, he cleared his throat again.
"It is currently 10:30 AM. We will now begin a 48-hour special training session..."
"48 HOURS!?"
"That's right. 48 hours."
Sakiko cut him off, nearly screaming. 48 hours! Two full days! She thought she had misheard him.
"No! Let me go... 48 hours is impossible. The band just formed; I have so many things to prepare."
Rin placed an index finger gently against Sakiko's lips. "What's more important—the band, or Mutsumi?"
"..."
Rin's words silenced her instantly. For Mutsumi's sake—that was the one reason Sakiko could never refuse.
At the same time, Karen leaned in with a blissful smile, stroking Sakiko's burning cheek.
"Don't worry. We are going to make you forget everything over these 48 hours~"
Forget everything...
There it was again. If she could truly forget everything, perhaps it wasn't so bad.
Sakiko slowly closed her eyes. She couldn't hide her shameful parts, but she could at least close her eyes and pretend the others didn't exist.
Seeing her surrender, Rin glanced at Shion and Ai.
"Shion, Ai-chan, Sakiko is in your hands first. Use the small toys to stimulate her slowly. Don't go too far at the start."
"Leave it to me~" Shion was always interested in toy with others. Ai had no personal interest, but since it was Rin's order, she had to obey.
Even though Ai still lived at the Shinomiya manor, in reality, both she and her mother, Nao, were Rin's maids now.
Ai went to the cabinet and grabbed two oval vibrating toys. She clicked them on and pressed them against the slight mounds of Sakiko's chest, stimulating her with a clinical, robotic precision.
As for Shion... she didn't grab any toys. She watched Sakiko's face while her fingers gently kneaded and teased, searching for her hidden sensitive spots.
To Ai, this was a job. To Shion, this was playing with a brand-new toy... Hmph. As expected, these Ojou-samas are all just little sows!
Rin left Sakiko in their hands for now.
A party is only a party if everyone is involved. The goal was to deepen their connections; a one-sided display of shame wasn't enough. Everyone had to show their most depraved side for the bond to truly form!
Rin called Chika, Moeha, and Karen over to the area opposite Sakiko. For today's event, Chika and Moeha had worked hard to move Sakiko's chair directly across from several iron racks.
Rin cuffed Karen and Chika to the racks first. No special poses—just a simple "X" shape.
Moeha was left. she put on a pitiful face and looked at Rin.
" Big Brother... can I cuff myself later?"
"No."
Rin expressionlessly cuffed Moeha into the same pose as her sister. Then, he grabbed a set of small electric breast pumps from the cabinet and attached them to the three girls.
"GUH-EEEE!!!" As the switches were flipped, the transparent tubes began to fill with drops of milk. The faint scent from earlier instantly became a heavy, sweet aroma.
But he wasn't done. Rin finished by stuffing toys into the front and back of both Chika and Karen, giving each of their rears a heavy slap for good measure.
"Keep them clamped tight. If they fall out once before the bottles are full, I'm turning the intensity up another notch."
