""""?????""""
The four sisters were so stunned they didn't know what to say.
Daddy.
Itsuki actually called him "Daddy"!?
What the hell?
Itsuki, who usually avoided conflict and had even been resistant when Nino proposed the plan for everyone to be together—what exactly had happened between her and Rin to make her call him "Daddy"?
And playing this kind of kink game in private was one thing, but blurting it out in front of everyone? Itsuki was the youngest sister and called him "Daddy"; what about the four elder sisters? Were they supposed to follow suit?
While the others (except for Ichika, who lived alone) had noticed Itsuki was emotionally off for a while, they figured it was just "that time of the month." Itsuki had bounced back quickly, so they hadn't pried. Now, looking back, something significant must have happened during those days.
The four sisters were bewildered, but Itsuki remained a "hiding ostrich," burying her face deep into the pillow.
"Itsuki called me 'Daddy.' As her older sisters, shouldn't you... ahem~" Rin teased.
"Pervert! Who would call you that!" Nino lifted her head slightly, glancing past Miku and Yotsuba at the blushing Itsuki. She spoke with a sarcastic edge. "No wonder she's so obedient. If she wants to play the good little girl, let her. I have no interest in being—"
"I... I want to, too."
Before Nino could finish, Ichika, never one to pass up a chance for chaos, gave a sweet "Daddy" and wiggled her ass. Think of it as acting practice, she told herself. Calling him that cost her nothing, and seeing Nino's annoyed face was a great bonus.
"Ichika, you..."
"Hehe~" Yotsuba followed suit with a mischievous grin. "I've been practicing my running lately. Give me a reward, Daddy~"
Seeing Itsuki, Ichika, and Yotsuba join in, Miku—squeezed in the middle of the five sisters—found her courage.
"I... I've been studying hard, too! Give... give me a reward." Trapped between her sisters, Miku couldn't wiggle her hips much, so she arched her back, offering her curves to Rin.
"You... you guys..."
Nino gritted her teeth. They had already stolen her "token of love" idea; now they were using this "Daddy" talk to seduce him!
Pia!
Rin's palm came down hard on Nino's butt.
"Ow!!!! Why do you keep hitting my ass!?" Nino snarled, glaring at him over her shoulder. But then...
Pia!
Rin slapped her again. He controlled his strength; it sounded loud but didn't truly hurt. However, being spanked while naked in front of all her sisters filled Nino with an overwhelming sense of shame. Her eyes began to mist over.
"Hmph. Your sisters all called me 'Daddy,' but you're being difficult. You deserve a beating!"
Rin slapped her again, the white, soft flesh turning a light peach-pink.
"Say it."
"I won't... Ugh!!!"
A small whimper escaped Nino's lips. Rin continued to spank her mercilessly. As he did, he noticed his palm was coming away slightly damp. He hadn't even started foreplay; he was just spanking her, yet this girl was actually getting wet from the punishment.
Rin wiped the moisture from his palm onto Nino's smooth, naked back.
"Tsk tsk... getting thrashed and you're already this wet. You're a real slut... I don't have a daughter like you!"
Rin spoke like a stern, disappointed father, delivering another sharp slap.
"I'm... I'm not. I'm not wet... Uuuuuh~"
Unlike her initial cries of pain or indignation, Nino's voice was now laced with arousal. The slaps, which used to be dry, now elicited a wet, squelching sound.
"Sluts need to be punished!"
Pia!
"No... I'm not a slut... Stop, I'm going to climax!!!!"
Pia!
As Nino screamed, Rin brought his palm down with finality. Her slender waist arched violently, and in the next second, Rin felt a wave of hot liquid hit his hand.
"Pervert... pervert..."
Utterly humiliated, Nino buried her face in the pillow, her trembling butt cheeks glistening with juices. Rin scooped up the fluid and rubbed it over her reddened, slightly swollen cheeks.
"I'll let you off this time. Next time you're disobedient, there will be more punishment!"
He stood up and pulled a pure white handkerchief from his bag, then walked over to Itsuki.
"Itsuki is the good girl. Time for the good girl's reward."
Itsuki was too far gone in shame to care what he said; she just kept her rear thrust up, waiting.
After days of "deep study," Rin knew their bodies inside out. With a practiced touch, he could make them flood with just a finger. Holding Itsuki's waist with one hand and the handkerchief in the other, he lined himself up and pushed forward.
"Ugh... Gkh!!!!"
The pain of being stretched open brought cold sweat to Itsuki's brow. She bit the pillow, her fingers digging into the sheets as if to tear them.
Rin didn't move immediately after taking Itsuki's virginity. He used the white handkerchief to catch the bright red blood of her broken hymen. Thanks to the "development" he had done previously, Itsuki's low moans of pain didn't last long.
However, Rin didn't stay inside her to finish. He pulled out and moved to Yotsuba, right next to her. The whole point of lining them up was to take all their virginities in a row!
"Ngh!!!" "Eek!!!" "Pervert!!" "Is big sister's body... comfortable?"
Seconds after taking Itsuki, he took Yotsuba. Then Miku, then Nino. Finally, with his cock stained with the blood of her four younger sisters, he took Ichika's virginity.
Rin then walked around to the front of the bed, holding the white handkerchief now stained with five distinct crimson "plum blossoms."
"This handkerchief is the proof that you five sisters will be together forever."
"Pervert..." Nino muttered, but she reached out and snatched the cloth. "Confiscated!"
Despite her words, Nino—who wanted the sisters to be together more than anyone—carefully folded the blood-stained silk and tucked it under her pillow.
The five sisters weren't just going to be together for this. In the future, they would get pregnant together. Five sisters, five bellies, one man. Together forever.
