"Breakfast is ready, get up."
Early in the morning, Nino's impatient voice rang from outside the door. Along with the sound of the door opening, Rin, still groggy from sleep, opened his eyes to see Nino dressed in a tracksuit. However, Nino's gaze wasn't on Rin's face; it was fixed squarely on his crotch.
"Ichika used to make me wake you up, and now you're making me do it again!? Breakfast is on the table! Hmph... pervert!"
Nino's face was flushed with a light pink hue. Last night, after Miku and Yotsuba had finished "serving" Rin, the room had gone silent, so the earplugs Itsuki had prepared for Nino hadn't been necessary.
Just thinking about the lewd things they had done in this room last night made Nino want to kick Rin right between the legs... compared to usual, the "target" was much more prominent this morning.
But in the end, Nino held back. After all, he was going to be the lover for all five of them in the future. It would be a problem if she broke him.
If he were at home, Rin would usually get up and head straight to the bathroom to calm down. Sometimes, if Mashiro saw him, she would help "handle" it, considering it a little extra morning protein. Nanami couldn't understand why Mashiro loved that taste so much... Nanami didn't mind eating it or even drinking it from a cup, but Mashiro would literally use his cum as a substitute for cream on her Baumkuchen.
Once he had calmed down slightly, Rin changed out of his shorts and T-shirt into casual clothes. After a quick wash, he headed to the dining area.
The four sisters were already seated at the table, eating in silence with their heads down. Aside from Nino's obvious annoyance, Miku, Yotsuba, and Itsuki were all blushing furiously.
"..." "..." "..." "..."
Rin looked around. Although Nino said breakfast was ready, there wasn't a plate set for him.
"Where's my breakfast?"
"Serve yourself! You haven't passed my test yet, so you're not a member of this house... Hmph, I'm not like some people who just throw themselves at you!"
Nino's words made Miku and Yotsuba bury their heads even deeper, their ears burning hot beneath their hair.
Watching Nino's huffy attitude, Rin suppressed a smirk and went to the stove to plate his own food. Salted fish, rice, and miso soup—it was simple but delicious. Nino's grumpy face made the meal even more enjoyable.
After breakfast, the four of them took the bento boxes Nino had prepared and headed for school. Usually, Maruo Nakano's driver would pick them up, but since their big argument with their stepfather, they had been commuting on their own.
The school wasn't far from their apartment. Unless they woke up late, they usually walked.
"He hasn't even passed the test yet. What were you two thinking? At least wait until it's official," Nino grumbled. "And you were so loud that Itsuki and I could hear everything!"
"Ahaha..." Yotsuba gave a silly laugh, while Miku remained silent with a red face. Nino didn't press the issue, and the four chatted idly, though today the center of the conversation was Rin.
The five sisters attended the same school but were in different classes. Before heading to her own classroom, Miku peeked into Ichika's room. Ichika was already at her desk, buried in a book. Even though she had decided to become an actress, she hadn't given up on her studies, using every spare moment to read and do homework, even during breaks at her acting workshop.
Miku shrugged, adjusted her backpack, and headed to her own class without disturbing Ichika.
Throughout the morning, Miku was distracted. She kept glancing at her backpack until the bell for the lunch break finally rang, allowing her to breathe a sigh of relief.
Usually, since they were in different classes, the sisters ate lunch with their respective friends. Miku didn't have many friends and usually ate alone, but today she pulled out her phone and messaged Ichika.
Miku: [Let's have lunch together today.] Ichika: [Sure~]
After agreeing, Ichika excused herself from the classmates who wanted to eat with her. Holding her wrapped bento, she went to Miku's classroom and waved. Seeing her, Miku stood up and left.
"My, my, what's with the sudden invitation to eat together? By the way, Miku, you haven't tried Nijika's cooking yet, have you? She made an extra portion for me when she was cooking for Ryo. I'll share some with you..." Ichika noticed Miku was holding a thermos. "Did Nino make miso soup? Give me a sip later~"
"Um..." Miku nodded. "Let's find some shade on the sports field."
"Huh? Just us?" Ichika was surprised. "Aren't Nino and the others coming?"
"No... just us."
Hiss...
Ichika sensed something was up. At school, they either ate with friends or all five ate together. Miku was acting strange, wanting to eat with her privately. Speaking of private meals, Ichika's mind immediately went to the "cuckold" persona she was maintaining. If she wasn't careful, Miku might forget her supposed fetish!
They found a quiet spot under a tree where other students and couples were also enjoying their lunch. They opened their bentos; Miku's was the same as breakfast—rice, fish, and a salad.
"Ooh~ it's been a while since I had Nino's cooking. I'll trade you this fried shrimp~"
The two enjoyed their meal. Whatever Miku wanted to say could wait until they were done. Since the lunch break was short, the portions weren't massive, and they finished within ten minutes.
Then, Ichika reached for the thermos Miku had set aside. As soon as she touched it, she felt something was wrong... why was it so cold?
Thermoses were usually for miso soup. If there was extra from breakfast, they'd heat it up and seal it so it would stay warm until lunch. Even a good thermos would radiate a bit of warmth, but this one... it wasn't even winter yet, and the thermos felt icy.
As Ichika unscrewed the lid, a chill wafted out. She had a bad feeling. A thermos keeps things at their temperature, whether hot or cold. Miku had clearly used ice. If it was ice, it wasn't miso soup... maybe a drink? It was a hot day, after all.
Her thoughts raced, but as the inner cap came off, she saw ice cubes and... two balloons?
Wait!!!
Ichika froze. Those weren't balloons. Those were condoms! And they were stuffed full—at least half a soda can's worth of fluid in each! And there was more than one! Along with the ice, they almost filled the entire thermos.
This... this can't be right!
She thought it was miso soup, but it was this?
Ichika looked at her sister in shock. Was this the real deal? And the amount... if it was real, it had to be Rin's. Where did Miku get this? She and Rin shouldn't be that far along yet, right? They'd only kissed. Miku was too shy for things to move this fast.
Did she get it from Kaede? That was the most likely scenario. Did Miku go to see Kaede behind her back?
ovo!?
Ichika was completely stunned. She stiffly turned her neck to look at Miku. "Why is your face so red!? Is it really that hot!?"
Miku looked down, avoiding her eyes. "This... this isn't miso soup. It's his 'Cheating Chicken Soup.'"
"Pfft—cough, cough!" Ichika choked on her own spit. Chicken soup? What the hell?
"W-why did you bring me 'chicken soup'?" Ichika's lip twitched. Even with her professional acting training, she was struggling to keep it together.
"Huh? Don't you like it, Ichika? Back in the wardrobe at the Hoshizuki house..."
Miku's words triggered a memory. When they were hiding in Kaede's wardrobe spying on them, they had seen this "play." Suzu, Nanami, and Mashiro had made Rin cum into a condom so they could give it to Kaede to drink.
"...."
Ichika finally understood. This "soup" was likely made last night, chilled, and brought here for her.
"I... I love it."
Acting training was truly useful. Ichika forced an excited, expectant smile onto her face.
Don't let your sister's kindness go to waste... I have a cuckold fetish. I have a cuckold fetish... This is just practice for a role. This is just practice... This is chicken soup. This is chicken soup...
"I... I'll take it home to drink. It's too conspicuous at school."
Even though she tried to hypnotize herself, and even though she'd seen Mashiro eat "fresh chicken soup" like it was a delicacy, Ichika really couldn't bring herself to swallow it. She regretted ever taking Miku to Kaede's place!
"You want to take it home?" Miku paused, then seemed to realize something. She looked around and lowered her voice. "Ichika, you want to take it back to use as 'material' for your 'practice,' right?"
"Right, right. Exactly."
Ichika breathed a sigh of relief at Miku's excuse, but she celebrated too early.
"The ice is already melting. If you wait until after school, it might go bad... if you want material for your 'practice,' I'll find a way to get you some fresh stuff later."
"...."
Miku had clearly made progress with Rin to get this. If Ichika didn't drink it, Miku might get suspicious.
After another round of self-hypnosis, Ichika tremblingly removed the remaining ice cubes. Miku thoughtfully handed her a utility knife from her pocket. After pouring out the melted water, Ichika checked to make sure no one was watching, sliced the condoms open, and poured the cold "chicken soup" into the thermos cup.
There were two bags. One was from Miku's "breast-work" and the other from Yotsuba's "mouth-work."
Earlier, Kaede had seen Miku taking the condoms through the camera system and guessed what she was up to. Her only regret was that she couldn't see the look on Ichika's face as she drank it.
The two bags combined were about the volume of a soda can, filling half the cup. Rin's pungent, musky scent filled Ichika's nose. This was way beyond the pay grade of a girl who had only ever had a first kiss.
But... for her sister to be with the man she loved without guilt...
Fuck it! As the eldest sister, she'd do anything for them!
Ichika held her breath. Then...
Gulp, gulp, gulp, gulp.
The thick, viscous "chicken soup" filled her mouth, coating her teeth and tongue. Every corner of her mouth tasted it. While her instinct was to gag the moment it hit her throat, she was surprised... Wait, the taste isn't that bad?
She finally understood why Nanami and Mashiro could drink it so easily. There was a faint sweetness, and it wasn't unpleasant at all—almost like drinking a very thick, overcooked rice porridge. Once she overcame the psychological barrier, it was actually quite palatable.
Relieved, Ichika tilted her head back and drained the cup, an expression of "ecstasy" on her face for Miku's benefit. When she finished, she tilted the cup up to let the last few drops fall onto her tongue. She even licked the residue off her lips. Seeing Miku's happy expression made it all worth it.
Burp...
Ichika let out a satisfied burp, stuffed the empty condoms back into the thermos, and tightened the lid before handing it back to Miku. She couldn't leave evidence like that in a school trash can.
"Speaking of which... to get this much 'soup,' Miku, how far did you get with him? You must have gone all the way, right?" A flash of mischief appeared on Ichika's face.
"Eh... well... not yet." Miku's face turned bright red as she looked down. "He just... he used his fingers, and I used my chest and mouth..."
"I see~ Good progress. Keep it up... When do you plan to go all the way? I'll hide in the wardrobe and cheer you on~"
Once Miku makes it a done deal, I won't have to pretend to be a cuckold anymore!
"That... I don't know... maybe next week."
Miku smiled shyly, already imagining the "party" in her head. A party with all five sisters would be even bigger than the one at the Hoshizuki house! Ichika wouldn't need anyone else to satisfy her "fetish"; the five of them would steal Rin away from the Hoshizuki sisters, Nanami, and Mashiro together.
Next week was when Rin would take his re-test. Ichika didn't know that Nino and the others had already agreed. Once he passed, they'd hide Ichika in the wardrobe and then...
The four of them would cuckold her together!
