When she leaves the classroom, Yuki, a female teacher, crouches down and trembles. What on earth happened to her? A few days ago, Yuki was called to the gym storeroom and suddenly attacked by a masked student. She desperately tries to escape, but her resistance is futile and she is raped silently. She continues to be threatened and raped each time... and finally cries out in joy. A silent masked rapist. A colleague watches and rapes her. A no-panties, no-bra humiliation class. Continuous public rape in the classroom.
