Despite the misunderstanding, Kaede knew it absolutely could not deepen.
Therefore, she absolutely could not refuse... If she refused, he would certainly think she had a cuckold fetish and was already terminally obsessed.
However, due to the System, she could only be intimate with him after he had been intimate with another girl. Since she couldn't tell him about the System, doing this would also make him believe she had a cuckold fetish and was already terminally obsessed.
No matter the choice, the misunderstanding would deepen.
But... a coin doesn't just have two sides! There is a middle!
A brilliant plan formed in Kaede's mind.
Taking a deep breath, Kaede ran to her sister's room next door.
"Suzu... shower with me."
"....?"
Suzu tilted her head, looking at her sister in confusion... Shouldn't she be having a wonderful night with Rin Ito right now? She should be showering with him, so why ask Suzu? How many years had it been since they showered together?
Though she didn't understand what was going on, Suzu still nodded, grabbed a change of clothes, and went to the bathroom with Kaede. The two unbuttoned their uniforms, revealing the white, lace-trimmed lingerie underneath. After tossing the uniforms into the hamper, they brought their hands behind their backs.
With a faint snap, the heavy, bountiful fruits encased in pure white bras were exposed to the air.
Bending over, their fingers hooked the similarly pure white panties, pulling them down to their thighs. As they moved, the voluptuous breasts swayed with gravity.
Standing up, the soft, white fruits trembled as they pulled down their panties. Under the warm yellow light of the bathroom, the pink areolas atop the soft white mounds were the most dazzling sight.
Gulp...
Staring at the seductive softness on Suzu's body, Kaede subconsciously reached out and cupped it with her palm. A slight squeeze made it feel as if cream might overflow from her fingertips.
He would absolutely get addicted if he touched this, right?
"Kaede?"
Suzu looked at Kaede, who was pressing her hands against her own chest.
"N-Nothing." Kaede guiltily let go and rubbed her own chest. Though not as soft or as large as Suzu's, hers was a little perkier.
Honestly, both Kaede and Suzu's bust sizes far exceeded their peers; Suzu's was just even more impressive than Kaede's.
Kaede's gaze dropped from the dazzling pink downward. Below the slender waist and flat abdomen was a smooth, tightly closed line... Hmm, that part was no different from her own.
Warm, white steam sprayed from the showerhead, tinting the sisters' pale skin a rosy pink.
Staring at Suzu's body, Kaede hesitated for a long time before finally plucking up the courage, still keeping her head down, afraid to look at Suzu directly.
"Um... Suzu, he said he... wanted to... you know, with me."
"So? Don't you want to? Don't you always use your toy while fantasizing about him..."
"AHHHHHH!!!!"
Kaede yelled, cutting Suzu off... How did she know I secretly bought a small toy!
But this wasn't the time to think about that, and Suzu wisely stopped talking... Suzu knew more than just Kaede's little toy; she even knew where Kaede liked to be held when practicing Judo.
She had even secretly filmed many videos, planning to use them to tease her at a crucial moment. However... given Kaede's cuckold kink, they probably wouldn't be needed for teasing, but she could show them to Rin to add a little spice.
"It's just... you know my kink, so... can you replace me with him..." Kaede endured the shame that made her feel like digging a three-story basement with her feet and told Suzu her plan.
"???"
Suzu stared at her sister in astonishment... When she puts a question mark, it's not because she's confused; it's because she thinks you're confused.
Rin had accepted her, but he wanted the first time to be with Kaede.
But... Kaede wanted Suzu to replace her!?
She wanted Suzu to replace her for their lover's first time!?
"When we were little, every time I pretended to be you to play a trick, he found out."
"It's okay. I'll cover his eyes, and I'll talk to him from the side. He won't notice..."
Suzu was stunned at her sister's words... Not only was she asking Suzu to sleep with him, but she was going to do the voice acting from the side!?
Covering your lover's eyes and handing your lover over to someone else... isn't this a common plot device in cuckold manga?
Has she gone completely cuckold-brained?
Suzu previously thought Kaede just read it for the thrill, but now she was convinced Kaede was terminally obsessed.
"Please, Suzu!"
This was Kaede's plan. She had already confessed to Suzu... so what if she was a little more humiliating and let Suzu think she was cuckold-brained? Letting Suzu go first, and then taking her turn... Letting Suzu go first would both circumvent the System and perfectly deceive him!
While Rin had recognized her when they swapped roles for pranks, and even recognized her by her bust size and the mole on her chest when naked, Kaede didn't believe he could recognize them while blindfolded!
Hmm, it would be best to tie his hands as well, so he'd lose the ability to recognize her by her breasts.
She absolutely could not be discovered by him. Although she knew he was faithful, men...
They definitely want the best of both worlds. If he thought she really had that kind of fetish and started actively seeking out other girls, she wouldn't even have time to cry!
She couldn't refuse, and she couldn't go first.
Blindfolding him and having Suzu replace her was the best solution.
Suzu stared deeply at her sister... She had some doubts before, but now it was confirmed: Kaede was obsessed with cuckolding.
But... it didn't matter. No matter what strange fetish Kaede had, she was still the sister Suzu wanted to be with forever.
"I can do it."
Seeing Suzu agree, Kaede's eyes instantly sparkled... Only the first time was complicated. Every time after that, doing it with Suzu would be fine.
Kaede crouched down and squeezed shower gel into her palm.
"I'll scrub your back. We have to wash every single spot clean. It would be bad if he smelled anything weird~"
"Mhm..."
...
The sisters took a long shower. After meticulously washing every hidden spot on their bodies and confirming there were no strange odors, they left the bathroom together.
"Suzu, stay behind me. I'll go in first to blindfold him, then you come in."
Suzu nodded and quietly followed Kaede. However, shortly after Kaede entered the room, she poked her head out and waved at Suzu outside. "He went back to his house to shower. He's not here yet. Suzu... hide in the closet first!"
"...." Suzu glanced at the closet... Yesterday, she and Rin hid in this very closet to watch Kaede get off.
And today... Kaede would be standing nearby, watching Suzu and her boyfriend surrender their respective virginities to each other.
