一个高中女生今天过得很糟糕。她因扰乱课堂而受到纪律处分，并被送往清洁实验室设备。她觉得自己很饥渴，于是用一个看起来像阴茎的试管来自娱自乐。不幸的是，一位路过的老师发现了她，并用额外的设备对她进行了进一步的训练。当一队老师一个接一个地羞辱她时，她很痛苦。最后逃回家，她发现自己的审判还没有结束，因为她的父母决定给她一个相当反常的性教育。

A high school girl has a very very bad day. She is disciplined for disrupting class and sent to clean lab equipment. Feeling horny she uses a phallic looking test tube to pleasure herself. Unfortunately a passing teacher spots her and proceeds to further discipline her with additional equipment. She suffers as a parade of teachers dish out a variety of humiliations one after another. Finally escaping to home she finds her trials are not over as her parents decide to give her a rather perverse sexual education.
