The bedroom door remained shut, silence reigning within.
In the living room, the five naked sisters sat on the tatami, looking at each other in stunned silence. Yotsuba glanced at a distracted-looking Ichika.
"Ichika... if you want to keep going, do it. We'll watch the door for you. If Nijika comes out, we'll block her."
"Uh." Ichika snapped out of it, looking embarrassed. She had been wondering why Nijika had suddenly turned into a brat, but her sisters thought she was just "holding back" her lust.
Ichika understood. In their eyes, she was currently being "cucked," and she was supposed to be listening to her man being "stolen" in the next room.
"It's okay." Miku reached out and guided Ichika's hand back to her crotch. "Enjoy yourself, Ichika... we'll steal him back for you later!"
"That's right," Nino said confidently. "Leave it to us!"
A guilty-looking Itsuki nodded. "Leave it to us."
"I..." Ichika wanted to cry. Why are you guys so united today? You usually fight all the time!
"Then... then I'll leave it to you." Ichika was glad her acting had improved, otherwise her face would have looked more like she was in pain than in pleasure.
It was hard to hide things from sisters who grew up together. Nino and the others saw the awkwardness in her eyes. It was one thing to have a sex party; it was another to masturbate in front of your sisters while imagining your boyfriend with another girl. It was too perverted.
Ichika still wanted to maintain some dignity as the eldest sister.
"It's getting late. Maybe... you guys should head home? Nijika is just temporarily angry. I'll talk to her and clear things up."
After some hesitation, the four sisters agreed. Nijika was their secret ally and Ichika's friend. To satisfy Ichika's "special fetish," Nijika would likely keep the secret.
"Get home safe."
After waving them off, Ichika returned to the living room and stared at the bedroom door. She suspected this was all one of Rin's elaborate plans.
Nijika was an angel; how could she suddenly become a bully? And Ryo had stayed at Rin's place before; surely she knew about Kaede. Had she really never mentioned it to Nijika? She found that hard to believe.
I'll ask them exactly what's going on once they're finished.
Ichika stretched and crept toward the bedroom door, pressing her ear against it. She heard nothing.
Fine... I'll just do some homework while I wait.
She laid out her textbooks and pens, but she froze. Usually, she could study anywhere, even during loud rehearsals for acting class. But now, her eyes kept drifting toward the bedroom door.
Thinking about Rin, Nijika, and Ryo doing depraved things inside made her heart itch. She couldn't focus. Knowing Rin's stamina, they would be in there for a long time.
If I do a little something out here, they won't find out!
In the living room, Ichika was suppressing her moans.
Inside the room, Nijika was sitting on the bed, hands braced at her sides, using both feet to feel Rin's heat. Her movements were becoming more practiced, her soles clamping his shaft from both sides as if she were playing with a toy. She didn't even notice the wet patch forming on her own skirt.
"Mmm!"
With a low groan from Rin, Nijika held her breath. She wasn't just playing with her feet anymore; some of his fluids had splashed onto her skirt.
Huff... huff...
After taking a few deep breaths of the musky air, Nijika snapped back to reality.
!!!!!
Realizing what she had just done, Nijika's shoulders shook with shame. The "Queen" persona vanished instantly, replaced by the blushing, panicked girl.
"Pah!" Rin spat out the pantyhose and looked at her with a smile. "So? Stress relief, right?"
"...Yes." Her voice was like a mosquito's buzz. Teasing someone—especially an authority figure like Rin—was incredibly cathartic. The role reversal was thrilling.
But now that the thrill was over, she looked at her sticky legs and didn't know what to do.
"It's good stress relief, but... it's not enough. There's something even better. Want to try?"
"Something better?" Nijika stared at Rin's crotch, her face crimson. Does he mean actually having sex?
"The environment here is too poor. If we're going to do the real thing, we should find a better place. I don't want Nijika's cute voice to be heard by the neighbors."
"Then what do you mean... eh?"
Nijika followed Rin's gaze to Ryo. Ryo was still tied up on the bed, wiggling like a caterpillar.
"Mmm?" Ryo blinked in confusion.
Rin tensed his muscles and snapped the ropes holding him, then reached over to remove the gag from Ryo's mouth.
"Nijika, half of your stress comes from Ryo, doesn't it? You worry about her more than a mother would. You're even getting gray hairs."
"Eh... yeah." Nijika nodded. "When I found out Ryo borrowed all that money, I thought the world was ending..."
Nijika began listing Ryo's sins. Ryo tried to protest at first but soon went quiet, listening to the scolding. If Nijika was the mother, Ryo was the troublesome daughter. Poor grades, borrowing money from classmates and loan sharks—Nijika had basically raised her, supervising her studies and her life. Ryo shamelessly relied on her.
"Since so much of your stress comes from Ryo, you should vent it on her."
Rin held Nijika's calves and lifted her sticky, messy feet toward Ryo's face. Seeing Nijika's juice-covered feet coming toward her, the tied-up Ryo shook her head helplessly.
!!!!
Nijika held her breath and swallowed. Seeing the usually shameless and aloof Ryo looking so helpless, a little devil emerged in Nijika's heart.
The little devil spoke to Ryo.
"Lick them clean."
