The Sisters' Trial
I followed Priest Chidin through the church, taking in every corner. The atmosphere was plain to the point of being dull, yet it suited the quiet forest village of Cashew perfectly.
“This is the nuns’ quarters.”
When the priest knocked on the weathered wooden door, overlapping footsteps echoed from within.
“Pardon the intrusion.”
The door opened to reveal a modest room: simple beds lined up beside prayer desks, and neatly folded robes. Priest Chidin stepped inside first. The nuns paused their tasks and rose, quietly clasping their hands together.
“This is the brother who will assist us tonight.”
The nuns turned their gazes toward me.
“I believe you all know of the renowned brother from the village.”
A brief silence settled over the room. Some eyes held wariness, while others carried curiosity and interest.
“Brother Kang Seo-ja has come to serve the church without expecting anything in return. I hope you will welcome him with open hearts.”
“If Brother Kang Seo-ja has come with such intentions, there is no reason for us to refuse.”
The one who answered was a nun with long red hair that covered one eye. At her words, the others nodded quietly. She was likely the head nun. With her approval, the tension in the room eased slightly.
“Then I shall see you tomorrow, Brother…”
After guiding me to the quarters, Priest Chidin left. Once the door closed, the nuns cautiously glanced my way. They seemed hesitant, so I spoke first.
“Where should I begin?”
“If you start now, it will be quite demanding.”
“It’s fine. To tend to all four of you here, I should begin immediately.”
“Ah… such a devoted heart…”
The red-haired nun approached me. Her eyes gleamed with allure—clearly someone whose desires had built up—yet she maintained a composed demeanor, as if restraining her true nature.
“I’ve heard that nuns require a man whenever they use holy power.”
“Yes, but we cannot always burden the brothers, so we pray and keep our hearts in check.”
“Suppressing such urges must be difficult.”
“Novice nuns may struggle at first, but those with experience manage well enough.”
The red-haired nun clasped her hands and bowed.
“We are grateful that you came knowing our circumstances.”
“I came of my own will, so there’s no need to feel burdened.”
She smiled faintly and lowered her posture.
“Then… we shall prepare. Sisters, assist me.”
“““Yes, Sister Superior.”””
Following the red-haired woman, the nuns gathered around me. With careful hands, they removed my leather armor and underclothes, folding them neatly.
“I hear you are an adventurer.”
“Yes, an E-rank adventurer.”
“It’s impressive for a man to be an adventurer.”
“It would be difficult alone, but I have companions who help me—just as you sisters help one another.”
The red-haired nun, now kneeling, reached for my thigh and slowly traced upward. The others watched in silence.
“Indeed.”
Before long, her hand found my manhood. With practiced restraint, she stroked it gently—hands that knew a man. As the head nun, she seemed accustomed to both controlling her desires and receiving a man’s service.
“Then… Brother, I shall begin. Haum.”
She parted her lips and took me into her mouth, moving her head slowly and deliberately, as if savoring the taste.
“Chup… chup… chup…”
Though her actions were meant to relieve pent-up desire, she did not rush. She maintained that same controlled atmosphere from the start, steadily building my pleasure with a precise rhythm.
Then—
Pop~
“Huu… ha… Thank you, Brother.”
The red-haired nun released me and stepped back.
“It would be too much to tend to the others as well. I shall stop here.”
She yielded her turn to the other nuns, assuming I wouldn’t last. I understood the gesture. In this world, most men were weak at night and needed herbs to sustain themselves. She was likely being considerate.
“Even so, wasn’t that too brief for you, Sister Superior?”
“I felt plenty.”
“…Then I’ll spend time with the others, and if I have strength left, I’ll continue with you.”
“Hut… Understood.”
Smiling as if it were impossible, the head nun left the room.
“Then… I’ll start with the sister who helped remove my shirt.”
“Ah… Yes…”
Another nun took her place. All of them appeared restrained and composed, but the one I chose trembled from the very beginning. Judging by her reaction, her condition was poor.
“Then I’ll begin with my mouth as well…”
“No, I’m already prepared. You only need to remove your clothes, Sister.”
“Yes, Brother.”
The nun undressed herself. With only her veil remaining, her pale body was fully exposed—a voluptuous figure. Her nipples were already swollen and erect, and though she tried to cover herself below, she couldn’t hide the arousal dripping down.
As expected, she was already burning with desire.
“P-please… take care of me…”
Though she looked ready to pounce, she slowly turned and presented only her hips—a position meant to spare the man any burden. She wasn’t trying to indulge her own desires.
“Of course, Sister.”
Feeling her consideration, I didn’t refuse. I gripped her hips and rubbed my eager length against her.
Schlick… schlick…
“Hnn… ugh…”
The voluptuous nun trembled all over from just that light touch.
“You’ve been holding back a lot.”
“Ah… aah… ugh…”
Even as I teased her entrance, her fluids continued to flow. Despite our closeness, she kept her eyes tightly shut, refusing to show her desire. I admired her resolve, yet the church’s strict rules struck me as excessive.
“Then I’ll begin the service.”
Thrust…
“Hnnngh…!”
She cried out as I drove deep, quickly covering her mouth with her hand. But as the rhythm continued, moans escaped.
Thrust, thrust, thrust.
“Hah… ugh… ugh…”
Even during the act, she tried to suppress her voice, carefully accepting the man’s movements while hiding her own feelings.
Now I understood why the priest called it a “trial.” The church had created a divine law requiring men, yet they upheld their principles without exploiting them.
‘Rules I have no need for.’
I could feel the church’s consideration for the weak men of this world, but it was unnecessary for me. To someone who could handle any woman without issue, it felt like an inconvenient shackle—dimming the nuns’ allure and making the act feel almost like solitary indulgence.
Thrust… thrust…
“Huu…!”
The nun presented from behind reached her climax in silence.
“Haa… haa… ugh… I-I’ll… call the next sister…”
Weakened by her orgasm, she tried to push me away.
“No.”
Instead, I pressed forward another step.
Push!
“Hii…!”
Caught off guard, she jolted.
“Brother…! W-what are you doing…!”
She looked back with a half-melted expression.
“I intend to finish with each of you once.”
“You don’t have to push yourself…!”
Even as her face contorted in pleasure, she worried about the man. It truly deserved to be called a trial.
“I can see the sisters enduring their ordeal. I can’t just ignore it.”
“Ah… Brother… hnn…”
“Don’t worry. I’ll serve everyone in this room equally.”
“Ah… that…”
Seeing the voluptuous nun nod slightly, I resumed moving my hips.
Thrust, thrust!
She accepted me without stopping, her moans growing louder.
“Hah… haa… haang…!”
Sweat ran down her back as she finally lost control and cried out.
“Sister Miel seems to be enjoying herself.”
“Y-yeah…”
Now I understood why the nuns suppressed their excitement and acted so cautiously. If they showed too much pleasure to the man serving them, it would affect the others. Seeing an intense act might make the next nun crave the same, eventually burdening the man until the final sister received nothing.
Knowing this, they restrained their personal enjoyment as much as possible.
Thrust!
“Hee…!”
Their reserved attitude made sense. So I simply had to prove myself to all four nuns here.
“You have a lovely rear, Sister.”
“Aah…!”
This was why they called me the black-haired incubus.
