[Kirara] "I hope... I can at least make one friend. Before that, I hope I can at least have a normal conversation with my classmates."

At a certain shrine, a female student, Kirara Sono, prays with her hands together, muttering to herself. She has a serious problem: her gloomy appearance and shy, introverted personality have made it difficult for her to fit in with her class.

Her mental stress keeps building up, and the frequency of her masturbation to relieve it only increases. Not satisfied with the sex toys she bought online, she starts to wonder, "What would it feel like to have a real dick inside me?" further fueling her already strong sexual interest and fantasies. Despite these frustrated feelings, deep down, she can't give up on having a sparkling and fulfilling student life.

Maybe if she changes, if she gains confidence, the situation might change. But people don't change so easily, and lacking the courage, she had no choice but to rely on God.

After finishing her prayer, she was thinking of indulging in her daily masturbation when she heard a woman's seductive voice coming from the nearby forest.

Cautiously approaching the source of the voice, the moans became clearer, and hiding behind a tree trunk, Kirara saw a young male and female student engaging in outdoor sex!

[Kirara] (I have to leave quickly! I shouldn't be peeking...)

Witnessing the affair, Kirara can't take her eyes off the bestial, rough sex. Watching the girl—a gyaru—enjoying herself as she's thrust from behind, Kirara's lower abdomen begins to feel a shameful heat. Even though she knows it's wrong, she can't suppress her excitement in the face of the lewd scene, and Kirara's hand involuntarily reaches for her own crotch.

While harboring feelings of envy and jealousy towards their lively appearance, in contrast to her own depressing days, Kirara continues to masturbate while suppressing her voice, reaching climax at the same time as the woman.

And then, after the act. What jumped into Kirara's eyes, still reeling from the afterglow of her orgasm, was an unexpected sight. The woman, having separated from the man and now alone, grabbed her hair and removed it—a wig—revealing clear and lustrous black hair. The gyaru's true identity was Hikari Amamiya, a classmate Kirara admired!

[Kirara] (Why is Amamiya-san here!? She seems like the last person who would be involved in something so lewd.)

[Hikari] "Why don't you come out instead of lurking around, Sono-san?"

Hikari, who had noticed Kirara's presence while she was peeking and masturbating during the sex, spoke, and her words were enough to make the utterly confused Kirara scream.

[Hikari] "Did you enjoy your masturbation that much?"

[Kirara] "I-I'm sorry... I didn't mean to peek on purpose. I knew it was wrong, but my body got hot and my hand just moved on its own. And then I got absorbed... I'm really sorry! P-Please forgive me!"

Resigned, Kirara comes out in front of Hikari and apologizes for peeking with such force that she might as well be prostrating herself. But the words that came out of Hikari's mouth were neither forgiveness nor condemnation, but a question about whether she was interested in sex.

Kirara, still confused, answers the question honestly, confessing that she considers herself to have a strong sexual interest, that she only masturbates because of her daily frustrations, and that she wants to change her shy and gloomy self, which is the cause of her frustrations, and live a normal youth.

[Hikari] "Then, why don't you join us in our slutty activities and have a fun youth with us? You can overcome your shyness through interaction, gain confidence as a woman, and most importantly, it feels good, so it's a win-win-win situation. How about it, want to have fun with us?"

[Kirara] "I, I..."

And so, Kirara, skillfully lured by Hikari, stepped into the world of slutty activities. What kind of encounters and events await her!?
