Konatsu Kashiwagi is a new math teacher whose big, sparkling eyes give her a cute, almost animal-like charm, hiding her deeply dedicated nature as an educator. Raised in a family of teachers, she has now obtained her teaching license and officially joined the school staff. During university, she was part of an e-sports club, revealing a nerdy side passionate about gaming, yet she also maintained excellent academic performance. Her talent and enthusiasm have quickly made her a standout figure at the school.
However, under the guise of a routine health checkup, she is subjected to an absurd and degrading physical examination that turns intensely erotic. Stripped naked in front of students, her body is inspected in humiliating detail—measurements taken of her areolas, vaginal size, and every intimate area without regard for privacy. Using a speculum, examiners probe deep inside her, discovering something pale and mysterious within, creating a bizarre and shocking scene.
Then, under the pretense of a gynecological exam, a vibrator is brought out, thrusting her into an unimaginable situation. Overwhelmed by pleasure, she arches her back in violent spasms, squirting copious amounts of arousal fluid. With students and colleagues watching, she is forced into actual sexual acts, moaning in high-pitched ecstasy—this is no ordinary medical checkup.
When asked, "Teacher, are you feeling good?" she gasps, "I-I'm not feeling anything... at all!"—but her words ring false. Her mouth is silenced from above and below, completely trapped in a whirlpool of orgasmic bliss, lost in a dreamlike state of surrender.
The traumatic experience etches itself into her mind so deeply that the lessons of her math class no longer matter at all.
