"Oooooh..."
After her back arched and her body went rigid, Kaede collapsed onto the bed. The soft white mounds on her chest gradually settled as her breathing calmed, and the blush emphasizing their existence slowly faded.
Kaede, still lost in the afterglow, had no idea that two pairs of eyes had been watching her from the closet.
After resting for a while, Kaede dragged herself off the bed. She briefly adjusted her messy uniform and, with slightly unsteady legs, left the room, rolling up a damp bedsheet as she went.
Only when the quiet click of the door closing reached his ears did Rin finally relax.
Pulling the closet door open, Rin and Suzu climbed out.
The closet's cramped space prevented heat from dissipating. Suzu's shirt was soaked with sweat, clinging to her skin and revealing the outlines of her bra and a faint hint of flesh. Her cheeks were flushed with an alluring crimson.
Her blue hair was messy, and a few strands clung to her forehead, somehow caught between her cherry lips. But the worst part was the black pantyhose wrapping her legs beneath the pleated skirt.
The black pantyhose was now stained dark, with white smudges standing out clearly.
Suzu looked down at her soiled pantyhose.
After a moment, she used her fingertip to gently scrape the soiled spot on the pantyhose, then brought the finger to her nose for a light sniff—a smell she had only occasionally caught in the morning when she and Kaede would raid Rin's room.
"Suzu, you..."
Before Rin could finish, Suzu looked up at him, a small, fragrant tongue poking out from her cherry lips. She smeared the stain from her fingertip onto the tip of her tongue, drawing a thin, silvery thread, before sucking the finger into her mouth.
The combination of innocent eyes and a seductive action made Rin's heart pound. He looked away and took a deep breath.
"Suzu, you... you... you shouldn't do things like that anymore."
Suzu didn't reply but lowered her gaze... Rin, having just been released from Suzu's pantyhose-wrapped legs, hadn't even pulled up his pants. Every change in his body was visible to Suzu, who studied it with curiosity.
Even Rin, with his relatively thick skin, blushed under Suzu's scrutiny. In the dark closet earlier, Suzu had only used her hands and legs to feel. This was the first time she had observed Rin's body in a well-lit room.
Curiously, Suzu reached out a hand towards Rin.
"Don't..."
He had nowhere to hide in the closet, but now, outside it, Rin had room to back away. Although he wasn't fully grabbed, he still managed to soil Suzu's hand.
Suzu looked at her soiled hand, then licked her palm clean like a kitten preparing to wash its face.
"Kaede went to shower. She'll be back in about half an hour."
"..."
Half an hour, not too long, not too short... Was Suzu hinting at something?
Rin pretended not to hear and ignored her suggestion.
Seeing Rin's lack of reaction, Suzu walked straight to the bed, expertly unlocked Kaede's phone, and handed it to Rin. If Kaede had been gone longer than a shower, Rin didn't want to think about what else Suzu might have done.
Rin took the phone and glanced at it. The screen showed the cover of an adult manga.
"Why are you showing me this?"
Rin's heart pounded. Could they have found out about his adult manga career?
"To look at the plot," Suzu said flatly.
"The plot?"
Before looking at the plot, Rin glanced at the tags... NTR? What the hell?!
Rin skimmed the short manga. It was NTR (Netorare/cuckolding), but not in the traditional sense. The victim (cuckold) had become female, and the 'Yellow Hair' (the villain/cheater) had also become female.
Though slightly rude, Rin exited the manga app and opened the browser to check the history... Not just manga, but Kaede was also reading erotic novels, and the titles alone told Rin they were similar stories.
No wonder...
"Kaede has this kind of fetish?" Rin froze, then broke out in a cold sweat. His previously aroused body cooled down considerably. "Wait... did Kaede know we were in there? Or did she tell you to do this?"
Suzu shook her head.
"I found this when I was taking secret photos."
Rin involuntarily sighed in relief. "...Secret photos?"
Suzu handed Rin her own phone. It contained many secretly recorded videos of Kaede 'practicing Judo.' Rin quickly skimmed them and deleted them.
After deleting them, a thought occurred to Rin. Secret photos? Wait! Did Suzu set up a camera in the closet for me?
No, no, no... that's not right. There's no light in the closet; she couldn't take pictures.
"So, is Kaede constantly bringing girls home to introduce them to me because she wants to satisfy her fetish?"
"I don't know," Suzu said expressionlessly. "Maybe."
Hiss...
Rin sucked in a cold breath. Everyone has different fetishes, and the popularity of NTR manga and novels proved that many people shared this one.
As a [Former Pure Love Warrior], Rin didn't understand it, but he was profoundly shaken.
But fetish was fetish, and reality was reality.
Most people only read those stories for the thrill; they wouldn't actually hand their lover over to someone else in real life. But Kaede was now standing on a dangerous edge, trying to make the events of the manga and novels happen in reality.
And Suzu... Suzu was probably delighted by Kaede's newfound interest.
Rin hadn't failed to notice Suzu's feelings. Rin was a man, and he had dreamed of having both sisters, too, but only in his imagination.
Ethical issues aside, though he was a transmigrator, he hadn't awakened a cheat or bonded with a system in 24 years; he was just an ordinary person.
Rin wanted a harem, but as a Pure Love Warrior, it remained a dream.
Only children want everything; adults know they can't handle it. Rin was worried that he wouldn't be able to handle a woman on each arm.
Since he chose to be Kaede's boyfriend, he had to be faithful.
However... Rin glanced at Suzu's very messy black pantyhose. Although he hadn't fully had sex with Suzu, he hadn't done this with Kaede, either.
Even if it was forced, his commitment to fidelity had lost much of its convincing power.
The Pure Love Warrior had fallen. A tragedy.
"I... I'm going home now."
Rin, whose emotions were a complicated mess, unsure how to handle the relationship between the three of them, just wanted some peace and quiet.
...
Water streamed in the bathroom.
Warm, white steam rose. Hot water poured down from above, running over Kaede's still-flushed cheeks. It gathered in the slight cleavage, shallower than her sister's, flowed down her flat stomach like a cascade of silver thread, passed over her plump thighs, and dripped onto the floor.
Kaede squinted, enjoying the warm sensation of the water. Taking a hot bath after completing her daily tasks felt especially good.
Kaede wasn't treating 'Judo practice' as a daily task; it was a daily task.
"Open System Log!"
The next second, a female voice rang in Kaede's mind, and the System Interface appeared before her eyes.
[Rin Ito and Suzu Hoshizuki engaged in physical contact. Reward: 1 Nurturing Point.]
[Rin Ito and Suzu Hoshizuki engaged in intimate contact. Reward: 150 Nurturing Points (Blood Relation Bonus 50%).]
[Kiss Unlocked. Remaining Time: 24 hours.]
[Hand Unlocked. Remaining Time: 24 hours.]
[Legs Unlocked. Remaining Time: 24 hours.]
[Rin Ito NTR Manga Proficiency +10]
[Daily Quest: 'Interest Cultivation' Completed. Reward: 100 Nurturing Points.]
Wait, wait, wait, wait, wait!!!!
System! What is the meaning of this?
[During the host's completion of the daily quest, Rin Ito and Suzu Hoshizuki engaged in intimate contact.]
Rin, the transmigrator, had lived for 24 years without a System, but Kaede had recently bonded with a System called the [Protagonist Nurturing System].
It allowed her to select a protagonist to nurture. Kaede chose Rin. Because Rin was drawing manga, the focus was set on various manga genres: major categories like Pure Love or NTR, and subcategories like Hypnosis, etc.
Rin thought Kaede didn't know what kind of manga he was drawing, but through the Protagonist Nurturing System, Kaede could see industry trends, Rin's sales, fan count, and other data.
By completing quests and earning points, Kaede could enhance Rin in various ways, not just drawing proficiency but all sorts of things.
Right now, Kaede was enhancing Rin's skills for Reverse-NTR manga.
In this world, NTR was the most popular genre, and Rin had previously only drawn wholesome adult manga.
NTR was popular, but many artists drew it. To stand out, his work needed a unique flavor.
Not NTR, but Reverse-NTR, which swaps the gender roles of the 'Yellow Hair' and the victim in traditional NTR manga.
Reverse-NTR not only catered to NTR enthusiasts but also encompassed the audience for traditional genres like Harem.
Besides all that, Kaede also had a selfish motive.
She only had Rin and her sister, Suzu, left. She knew Suzu liked Rin, too.
While Kaede didn't mind sharing her boyfriend with her sister, Rin was a very loyal person and had actively kept his distance from Suzu after they started dating.
If he drew Reverse-NTR, not only could he earn more money to improve their tight living situation, but it might also make him more accepting of Suzu.
But once Rin was selected as the protagonist, Kaede was stunned: Rin was the protagonist, and she had become the heroine... the heroine of a Reverse-NTR manga.
Her daily quest was now to 'get off' while reading Reverse-NTR manga.
The main way to earn Nurturing Points also became having an 'intimate connection' with women other than Kaede.
That might have been acceptable if she only did the daily quests.
But this damn System actually restricted her contact with Rin!
Any contact Kaede initiated with Rin while feeling desire was a forbidden act. She could only touch Rin in the same way another woman had just touched him.
For example, since Suzu kissed Rin in the closet, Kaede could now kiss Rin for the next 24 hours. The same applied to 'Hand' and 'Legs.'
[What kind of Nurturing System is this?!]
[The host selected the nurturing direction. This System has not interfered in any way. Please be assured, Host.]
[To better facilitate nurturing, the host must understand everything about the heroine in the Reverse-NTR manga. This will improve nurturing and also contribute to the host's relationship with Rin Ito.]
[Being cheated on will help our relationship?!]
[After seeing numerous women, if Rin Ito still loves the host, will that not make your relationship even stronger?]
It made perfect sense! It was so damn logical! Kaede couldn't even refute it.
She had to understand the content of his manga and the heroine's emotional journey. By becoming the real-life reference for his heroine, she could contribute to the creation of his best manga. She did the same when he was drawing Pure Love stories.
[What if someone steals him away?!]
[That is a problem with the host's lack of charm, not the System. Of course, this System will also help the host improve her charm.]
Fine.
Despite being tricked, Kaede didn't regret setting the System's direction to Reverse-NTR.
She saw Rin's hard work. It was okay now that she and Suzu were in high school and could take part-time jobs, but before that, Rin supported both households alone.
He went to school and drew manga. Although he pretended everything was fine in front of Kaede, she knew he pulled countless all-nighters to draw.
If his manga wasn't popular, he had to draw more to keep up the income. If it was popular, he wouldn't be so tired.
So... no matter the genre! As long as it made his manga popular and eased his burden, becoming any kind of heroine was fine!
Kaede's feelings were complex as she looked at the System Log detailing Rin and Suzu's intimate contact. Even without the System, Kaede had been thinking of setting up Rin and Suzu.
As the older sister, Kaede knew Suzu's feelings for Rin. The three of them living out the rest of their lives together would be nice.
But now... she was his official girlfriend, yet Suzu's progress was already faster than hers!?
Before the System, she had only kissed him at most. Now... Suzu had not only kissed him but also unlocked 'Hand' and 'Legs'!?
And she even got an [NTR Proficiency +10]!?
Kaede didn't know whether to laugh or cry.
Since it had come to this, it was the perfect time to appoint Suzu as the first 'Yellow Hair.'
Suzu was her sister, so when she had a deeper connection with Rin, Kaede would receive a Blood Relation Bonus for extra Nurturing Points.
But the thought of Suzu getting intimate with Rin behind her back made a pang of jealousy surge through Kaede. There was a difference between her sharing Rin and Suzu secretly 'stealing a bite'!
According to the System Log's timestamp, while Kaede was getting off reading manga, her boyfriend and sister were intimately engaging somewhere.
Could Suzu actually... try to steal Rin away from her?
No... impossible.
Not even Suzu could do that!
I am his heroine!
Never mind Suzu, even if Rin met nine other women who slept with him on his way to school, just like in the manga, he would still love her!
