"Mmm..."
After her waist arched and her body tensed, Kaede collapsed onto the bed, her soft, pale breasts heaving with each breath until they gradually settled, the flushed peaks softening like they were finally admitting defeat.
Still lost in the afterglow, Kaede had no idea two pairs of eyes were watching her from the closet.
It took her a good while to drag herself up, straighten her disheveled uniform, and roll up the soaked bedsheet before wobbling out of the room on shaky legs.
Only when the soft click of the door echoed did Ito Rin truly exhale in relief.
He yanked open the closet door, and he and Suzu tumbled out.
The cramped space hadn't let any heat escape; Suzu's shirt was soaked with sweat, clinging to her skin and revealing the outline of her bra and a hint of her flushed flesh. Her cheeks were still rosy.
Her blue hair was tousled, a few strands stuck to her forehead and caught between her cherry lips. But the worst was below her pleated skirt—the black pantyhose wrapping her legs, now stained dark with streaks of white that stood out glaringly.
Suzu looked down at her soiled pantyhose.
After a pause, she extended her index finger, scraping along the mess with her fingertip, then brought it to her nose for a light sniff—the scent she'd only caught occasionally in the mornings when she and Kaede would ambush Ito Rin's room.
"Suzu, you..."
Before Ito Rin could finish, Suzu lifted her eyes to meet his. Her delicate tongue darted out from her cherry lips, smearing the mess from her fingertip onto the tip, drawing a short silvery thread, before popping the finger into her mouth.
That pure gaze paired with such a seductive act made Ito Rin's heart pound. He averted his eyes and took a deep breath.
"Suzu, you... you... don't do stuff like that anymore."
Suzu didn't respond, her gaze drifting downward... Ito Rin had just pulled free from her pantyhose-clad thighs and hadn't even zipped up yet. Every change in his body was on full display, and Suzu studied it curiously, taking in every detail.
Even with his thick skin, Ito Rin flushed under her stare.
The closet had been pitch black earlier; she'd only felt him with her hands and legs. This was her first time seeing him clearly in a well-lit room.
Curious, Suzu reached out toward him.
"Don't..."
In the closet, he'd had nowhere to dodge, but now out in the open, he backed away—though not before leaving a fresh mess on her hand.
Staring at her dirtied palm, Suzu licked it clean like a kitten washing its face.
"Kaede's taking a shower; she'll be back in about half an hour."
"..."
Half an hour—not too long, not too short... Was Suzu hinting at something?
But Ito Rin pretended not to hear, ignoring the implication.
Seeing no reaction, Suzu walked straight to the bed, unlocked Kaede's phone with ease, and handed it to him... If Kaede weren't just showering, Ito Rin dreaded what else Suzu might do.
He took the phone and glanced at the screen: the cover of an adult manga.
"Why are you showing me this?"
Ito Rin's heart skipped—had they found out about his dive into smutty comics?
"Look at the plot," Suzu said flatly.
"The plot?"
Before diving in, Ito Rin glanced at the tags... What the hell was "cuckold" doing there!?
He skimmed the short comic. It was cuckold-themed, but not the traditional kind—the victim was female instead of male, and the homewrecker was a woman too.
Though it felt rude, Ito Rin exited the app and checked the browser history... Not just comics, but erotic novels Kaede had been reading. From the titles alone, he knew they followed similar plots.
No wonder...
"Kaede's into this kink?" Ito Rin froze, then broke into a cold sweat, his lingering arousal cooling fast. "Wait... Did she know we were in there? Or did she put you up to this?"
Suzu shook her head.
"I found out when I secretly recorded her."
Ito Rin instinctively relaxed at her words. "...Secretly recorded?"
Suzu handed him her phone, filled with videos of Kaede's "solo sessions." After a quick look, Ito Rin deleted them all on impulse.
Only after did it hit him.
Secretly recorded? Wait! Had Suzu set up a camera in the closet ahead of time, waiting for him?
No, no... That couldn't be; no light in there for filming.
"So, all this time Kaede's been bringing girls home to meet me just to feed her kink?"
"Don't know." Suzu's face was blank. "Probably."
Hiss...
Ito Rin sucked in a breath. Everyone had their fetishes; the popularity of cuckold comics and novels proved plenty of people got off on it.
As the [former pure love warrior], Ito Rin didn't get it, but he was shook.
But kinks were kinks, and reality was reality.
Many just watched for the thrill, never actually handing over their partner. But Kaede was teetering on the edge, turning fiction into fact.
And Suzu... Suzu was probably thrilled about Kaede's interest.
Ito Rin wasn't blind to Suzu's feelings. He was a guy; he'd fantasized about having both. But it was just fantasy.
Morality aside, as a transmigrator, he'd lived 24 years without cheats or systems—plain ordinary.
He'd love a harem, but as a pure love warrior, it stayed a dream.
Kids wanted it all; adults knew they couldn't handle it.
Left-and-right embraces might break him first.
Having chosen to be Kaede's boyfriend, he had to stay faithful.
But... Ito Rin glanced at Suzu's disastrously stained pantyhose. He hadn't fully taken her, but this was something he and Kaede hadn't even done.
Forced or not, his "faithfulness" was shot.
The pure love warrior had fallen.
Sad.
"I... I'm heading back."
Unsure how to handle the trio's tangled mess, a conflicted Ito Rin wanted some alone time.
...
In the bathroom, water pattered down.
Warm steam rose as hot water cascaded from above, tracing her still-flushed cheeks, pooling in the shallower valley of her breasts compared to her sister's, sliding over her flat stomach like silvery streams, gliding over her plush thighs before dripping to the floor.
Kaede squinted, savoring the cozy warmth of the shower. Finishing her daily task and following with a hot bath felt extra satisfying.
Kaede didn't see her "solo practice" as just a habit—it was literally a daily quest.
"Open system log!"
In the next second, a female voice echoed in her mind, and the system interface popped up before her eyes.
[Ito Rin and Hoshizuki Suzu had physical contact: +1 development point.]
[Ito Rin and Hoshizuki Suzu had intimate contact: +150 development points (blood relation bonus 50%)]
[Kissing unlocked: 24 hours remaining.]
[Hands unlocked: 24 hours remaining.]
[Thighs unlocked: 24 hours remaining.]
[Ito Rin's cuckold manga proficiency +10]
[Daily quest 'Interest Cultivation' completed: +100 development points.]
Wait, wait, wait, WAIT!!!
System! What the hell is this?
[During the host's daily quest completion, Ito Rin and Hoshizuki Suzu engaged in intimate contact.]
Ito Rin, the transmigrator, had lived 24 years without binding a system, but Kaede had recently bound one called [Protagonist Development System].
She could select a protagonist to nurture, so she picked Ito Rin. Given his manga work, the focus was on various manga genres—from broad ones like pure love or cuckold to niches like hypnosis and more...
Ito Rin thought Kaede didn't know what he drew, but through the system, she could see industry trends, his sales, fan counts, and all the data.
By completing tasks for points, Kaede could enhance Ito Rin in all sorts of ways—beyond drawing skills, various boosts.
Right now, she was boosting him in reverse cuckold manga.
In this world, cuckold genres had the biggest audience, but Ito Rin's prior work was pure love smut.
Cuckold was hot, but competitive. To stand out, it needed a twist.
Not straight cuckold, but reverse—swapping the genders of the homewrecker and victim.
Reverse cuckold appealed to cuck fans while pulling in harem and traditional crowds.
Plus, Kaede had her own motives.
Now it was just her, Ito Rin, and Suzu. She knew Suzu liked him too.
Kaede didn't mind sharing with her sister, but Ito Rin was Mr. Monogamy—after dating her, he'd kept distance from Suzu.
Him drawing reverse cuckold could earn cash to ease their tight finances, and maybe open him up to accepting Suzu.
But after selecting him as protagonist, Kaede was stunned: He was the lead, and she became the heroine... in a reverse cuckold manga.
Daily quests turned into watching reverse cuckold comics and getting off to them.
The main point source? Him getting close with women besides her.
Fine, whatever—she could stick to dailies.
But this damn system restricted her contact with him!
If she approached him with desire, it was forbidden. Only after other women touched him could she do the same—for 24 hours.
Like earlier: Suzu kissed him in the closet, so now Kaede could kiss him for the next day. Same for hands and thighs.
[What kind of development system are you!?]
[The host selected the development path; this system has not interfered. Please rest assured.]
[For optimal development, the host must understand everything about the heroine in reverse cuckold manga. This aids development and strengthens the host's bond with Ito Rin.]
[Getting cucked helps our relationship!?]
[After experiencing many women, if Ito Rin still loves the host, doesn't that solidify your bond?]
Made sense! Too damn much sense! Kaede couldn't even argue.
Only by grasping his manga's content, the heroine's mindset, and becoming his real-life reference could she help him create his best work.
She'd done the same when it was pure love.
[What if someone steals him away!?]
[That's a host charm issue, not the system's. Of course, the system will help boost the host's appeal.]
Fair enough.
Though tricked, Kaede didn't regret choosing reverse cuckold as the path.
She'd seen Ito Rin's efforts. Once she and Suzu hit high school and could work part-time, things eased, but before? He'd supported both families alone.
School by day, manga by night. He acted casual around her, but she knew the sleepless nights.
Low sales meant more volume for income. Hits would let him relax.
So... whatever the genre! If it sold and lightened his load, she'd be any heroine he needed!
Seeing the log of Ito Rin and Suzu's intimacy, Kaede's feelings were mixed... Even without the system, she'd planned to pair Suzu with him.
As the big sister, she knew Suzu's feelings for him. The three of them together forever sounded perfect.
But now... She was his official girlfriend, yet Suzu was ahead!?
Before the system, they'd only kissed. Now... Suzu had kissed, plus hands and thighs!?
And proficiency +10!?
Kaede didn't know whether to laugh or cry.
Since it was like this, might as well make Suzu the first homewrecker.
As her sister, deeper interactions would net blood relation bonuses for extra points.
But thinking of Suzu sneaking around behind her back stirred a sour ache in Kaede's chest.
Sharing him with Suzu was one thing; her stealing bites in secret was another!
Per the log's timing, while she was getting off to comics, her boyfriend was getting intimate with her sister somewhere.
Suzu wouldn't... actually steal him from her, right?
No... Impossible.
Not even Suzu!
She was his heroine!
Even if, like in the manga, she went to school and bumped into 9 women who'd been with him—he'd still love her!
