Suzu is a student teacher. Plain in appearance and timid in nature, she becomes the target of the students' pranks from her very first day of training.
During a class one day, Suzu accidentally wets herself due to nervousness. From that moment on, she is raped by not only her classmates but even her fellow teachers. She endures golden showers, having her face treated like a rag, and brutal face-fucking. When she warns students who were skipping cleaning duties, they call her a "cheeky teacher" and subject her to reverse sexual punishment. She is face-fucked relentlessly, given an enema with school milk, and eventually erupts in a massive squirt! In a humiliating turn, Suzu becomes a human mop, using her hair and face to wipe up the mess.
Furthermore, the students unilaterally decide to turn her class into a self-study period, leading to a face-fucking orgy. While her teaching voice is quiet, she screams in ecstasy during sex.
Raped relentlessly every day in such an unreasonable environment, Suzu has transformed into the class's throat-toilet teacher.
