During class, Shiro was caught writing a diary exchange by her disliked homeroom teacher and ended up getting lectured after school. As the teacher's nagging lecture continued, Shiro gradually felt the urge to urinate due to tension. Reaching her limit, Shiro wet herself. Seeing this, the teacher couldn't contain his excitement, sucked on her urine-soaked panties, licked her vagina, and raped her. Furthermore, Shiro was imprisoned in a warehouse and subjected to further torture. In fear, Shiro wet herself again.
