"I enjoy being cheated on."
Ichika wanted to cry as she said it. This was exactly what Kaede had been grooming her for! Kaede had "lent" Rin to her, slowly feeding her the idea of shared lovers and the thrill of infidelity.
If I pretend to have this fetish, Miku won't feel guilty. And then, maybe we can all stay together.
Miku gasped. "Ichika... you like being... cucked?"
"Yes..." Ichika faked a blush. "Watching him with other girls... it makes me more excited."
Ssss... Miku took a sharp breath. It all makes sense now! The way he "accidentally" touched them under the bed... he wasn't just being a pervert; he was doing it to satisfy Ichika's secret kink! Miku felt a twinge of jealousy—not because he was a player, but because he was so dedicated to Ichika's pleasure that he would use the sisters as "tools."
But this also meant... she could be with him without losing Ichika.
"If Nino, Yotsuba, and Itsuki liked him too... we could be together forever," Miku thought. It was a dream they all shared—not wanting to grow up and grow apart.
Ichika saw the look in Miku's eyes. She had her.
"Nanami," Ichika called later, "Cancel tonight's tutoring."
She sent a series of messages. To the sisters: [Tutoring is cancelled tonight. Don't come over.] To Miku: [Sneak out and come to my apartment alone tonight.] To Kaede: [Since you're so confident, care to help me with something?]
Night fell. Miku arrived at Ichika's apartment, her face red. "Why am I here?"
"I'm taking you to see him."
"W-wait! Is it too early!? We haven't even officially dated!"
"Not for that," Ichika smirked. "You'll see."
They didn't go to Rin's house. They went to the house next door—the Starmoon residence. Ichika used a key she'd been given by Kaede and led Miku up to the second floor, into Kaede's bedroom.
"Get in the wardrobe," Ichika whispered.
The wardrobe was cramped. Miku's black-stockinged legs pressed against Ichika's bare thighs. Soon, the bedroom light flicked on.
Through the slats in the door, Miku saw two girls who looked like twins—Kaede and Suzu. Then came Nanami and Mashiro. Finally, Rin entered.
Miku's heart hammered against her ribs. Rin immediately pulled Kaede into a deep, hungry kiss.
"!!!!" Miku covered her mouth. He was with other women! And Nanami and Mashiro were just standing there?
Then, the clothes started coming off.
Miku watched, paralyzed, as the girls she knew as "tutoring partners" and "friends" transformed into creatures of pure lust. Nanami, the diligent student, was now on her knees, her mouth busy with Rin's thick, throbbing cock. Mashiro, the "angelic" artist, was using her delicate hands to stroke his balls, her eyes glazed with desire.
But the star was Kaede.
"You guys go first," Kaede panted. Her "punishment" from the system had her sensitivity cranked to double. If she didn't let the others wear him down first, she'd pass out in minutes.
Rin knew. He decided to tease her. "Suzu, prep her."
"Gladly~" Suzu pushed Kaede onto the bed and bit down on her sister's large, pale breast.
"Aaahhh!!!!" With double sensitivity, even a light bite made Kaede arch her back, her pussy instantly spraying a fountain of juices onto the sheets.
Next to them, Mashiro was deep-throating Rin, her throat muscles pulsing. She had become a natural at swallowing him whole without gagging. Behind him, Nanami was buried in his ass, her tongue flicking against his rim. Rin groaned, thrusting deeper into Mashiro's mouth with every lick from Nanami.
After feeding Mashiro a face full of semen, Rin turned to Kaede, who was trembling in Suzu's arms.
"I can't... I'm too sensitive... eeeeek!!!!" Before Rin even entered her, just the friction of his tip against her soaking entrance made Kaede's eyes roll back into her head.
Inside the wardrobe, Ichika was struggling to "perform." She had to pretend to be excited by this to convince Miku. She began to rub herself through her panties, mirroring the rhythm of the room.
Miku, meanwhile, was crying. The man who called her cute yesterday was now knee-deep in a literal orgy. "You player... you pervert..." she hissed under her breath. But she didn't leave. She couldn't pull her eyes away from the raw, carnal display.
The "party" lasted until 10:00 PM. Once the group headed to the shower, Ichika led a sweating, trembling Miku out of the house.
The wardrobe had been a sauna. Miku's white school shirt was translucent with sweat, clinging to her bra. Her tights were so soaked she could have wrung them out.
Back at the apartment, Miku finally exploded. "Ichika! They... they were..."
"Kaede is his actual girlfriend. The others are his... playmates."
Ichika explained everything—about her "deal" with Kaede and the "借" (borrowing) of Rin.
"Kaede thinks we aren't a threat. She thinks we're just 'little virgins' who can't handle him. She's looking down on us, Miku. So... how about we steal him for real?"
"We... the two of us? Can we really?" Miku's insecurity flared. The women in that room were stunning and experienced.
"Not just us. Nino, Yotsuba, and Itsuki too! There is nothing the five of us can't do together! We can have him, and we can stay together forever."
"And... satisfy your 'cuck' fetish?" Miku asked softly.
"Exactly~ Better to be cucked by my own sisters than by strangers."
Miku bit her lip, her heart racing with a mixture of fear, jealousy, and a new, dark excitement. She nodded.
"Okay. Let's do it."
