"Sister, if your best friend did erotic things with your boyfriend, what would you think?"
"Is this 'best friend' you're talking about actually yourself? This is a confessional for repenting sins. If you want to chat about friends, we can talk outside."
Marin's tone was as devout as a real nun's.
In reality, nuns have to take three sacred vows.
Chastity, poverty, and obedience. Of course, these are just vows; how they actually behave depends on their personal level of devotion to their faith.
As for nuns in the 2D world—especially in galgames or doujinshi—they exist purely to create a stark contrast. The concept of vows doesn't even exist in those settings.
However, even in reality, not everyone can immediately take these three vows. They first have to go through a long probationary period, take temporary vows that last for several years, and only then can they take their final vows.
By that time, the nun is usually around forty years old.
According to the setting of Perverted Nun, the characters are all young girls in their probationary period. Strictly speaking, engaging in erotic acts isn't explicitly forbidden for them.
Reality is reality, and games are games.
Having a slutty body completely decked out in sex toys underneath a thick, modest nun's habit... just like Sajuna right now. Merely hearing about it sounded incredibly arousing.
"You caught me... That's right, the friend I'm talking about is myself. The boy I like has someone else he likes. What should I do?" After saying this, Sajuna began unbuttoning Rin Ito's clothes while leaning close to his ear to whisper, "You wouldn't want the nun you have a crush on to find out you're in here too, would you?"
Nod, nod.
Rin Ito pressed his lips together and nodded repeatedly.
Sajuna wasn't just making this up on the fly.
Sajuna was currently cosplaying as a character named Sister Clarisa from the game, while Marin was cosplaying as Sister Shallon.
In Perverted Nun, there's a little boy who harbors a crush on Shallon at the church, so he uses confession as an excuse to chat with her. This was the role she had just assigned to Rin Ito.
In the game, the little boy's clumsy acting is naturally seen through by Shallon at a glance. However, Shallon doesn't expose him. Instead, she gently guides the boy until he finally realizes his childhood friend's feelings for him.
Ultimately, she helps the little boy and his childhood friend get together...
Of course, that is the content of the all-ages version. As for the DLC... the perverted nuns use the excuse of "getting the little boy used to girls" to ruthlessly milk him dry.
The final ending CG shows the little boy and his childhood friend getting married in the church with the nuns' blessings.
Truly a cause for celebration.
"Oh, lost lamb~ Loving someone is not a sin; you have no need to repent." Marin's voice drifted over from next door. Although they hadn't planned this in advance, upon hearing Sajuna's words, Marin instantly knew what kind of roleplay Sajuna was going for.
According to the setting, Shallon—played by Marin—can tell that the voice next door belongs to Clarisa. The two of them then team up to tease and toy with the innocent little boy.
"Even if that person is a servant of God?" Sajuna, having stripped off Rin Ito's top, now reached for his pants.
"Ito-sensei! You should be struggling right now, because you're currently cosplaying a pure little boy who likes Clarisa." Orie, her eyes filled with excitement, softly whispered the plot to Rin Ito.
Alright then...
Quickly getting into character, Rin Ito shook his head repeatedly, while Sajuna gently grasped his cock with her slightly cool, small hand.
"Even though your body is still so small, this part of you is just like an adult's~"
Shake, shake.
Rin Ito shook his head helplessly, just like a heroine being secretly violated in a doujinshi. To avoid exposing himself in front of the person he liked, he could only muffle his voice and allow his body to be toyed with. However, the stark contrast between Sajuna's petite figure and her bold lines couldn't help but arouse him.
Rin Ito would normally play these kinds of games with them, but experiencing it from the heroine's perspective was quite novel. Still, experiencing this would allow him to draw the heroine's perspective much better in his future manga.
In Kaede's system, a notification flashed: Reverse-NTR Manga Proficiency +1.
"A servant of God? Is it a priest? That won't do. Although priests don't take vows of chastity like nuns do, they must still remain celibate and cannot marry."
"No, the person I like is a nun." Sajuna roughly recited her lines. In the story, Clarisa speaks the secret the little boy is too afraid to admit out loud. "Sister, can you keep a secret for me?"
"Yes, we keep everything heard during confession strictly confidential, be it sins or secrets."
"The one I like is Sister Shallon. I even fantasize about being with her at night to relieve myself..." Sajuna continued to 'confess' on Rin Ito's behalf while stroking his hard length, and Rin Ito's reaction was... he looked as if he was about to cry from desperation.
With his deepest secret laid bare, in the game, this would be the moment a CG is displayed showing the little boy with tears in his eyes, desperately enduring Clarisa's sexual teasing.
"That's actually very normal. You haven't hurt anyone; just imagining it in your mind is not a sin."
On one side was Shallon's gentle guidance, and on the other was Clarisa's sexual torment... The little boy was completely played like a fiddle in the palms of the nuns' hands.
"Shh..." Sajuna lowered her voice. "Stand up."
Sajuna made Rin Ito stand up. This was slightly different from the game CG... In the middle of the confessional booth, there was a small window covered by a black curtain. Through this window, the penitent and the priest could pass items back and forth.
In the game, Clarisa made the little boy stand on a chair so that his aroused manhood faced the small window. For Rin Ito, standing up normally was high enough.
"You have to hold it in~ Shallon is right on the other side. If you can't hold it back, I'll pull this curtain open, and you'll end up dirtying Shallon over there~"
The little boy would nod tearfully and look at Clarisa with pleading eyes. Although Rin Ito couldn't look quite as pitiful as the CG, Sajuna had always been the one getting toyed with and edged by him. Being able to toy with Rin Ito like this now made Sajuna so incredibly turned on that she instinctively clamped her thighs together.
"Guh-uu~~~~"
Sitting on the chair, Sajuna continued to converse with Marin, following the game's confession plotline, while simultaneously toying with Rin Ito's cock using her hands and mouth.
However, Rin Ito was different from the little boy. In the game, the little boy is easily brought to his climax by Sister Clarisa, and as the story progresses, he is slowly trained by them until he finally became a capable man.
But in reality, it wasn't so easy for Sajuna to bring Rin Ito to climax. After quickly running through the game's script, Sajuna began her own 'freestyle improvisation'.
"Sister Clarisa... N-No... I can't hold it anymore!!!"
Rin Ito didn't tease Sajuna too much; feeling that he had reached the tipping point, he stopped holding back.
"You're already at your limit? What a weakling~ No, you have to hold it in. Hehehe~~~ If you can't hold it in, Sister Shallon will hate you~~"
As she spoke, Sajuna pulled back the curtain, while simultaneously dubbing over Rin Ito's climax like a bratty mesugaki.
"Pew pew pew~~~~ Sister Shallon is going to be covered in your filthy mess~~~"
