Hot for Teacher

Yumi is a busty, dark-haired teacher who knows how to give her students what they want, but she struggles to get what she needs in her own life. After a painful breakup with her fiancé, she finds herself sexually harassed by the vice-principal, leading to a situation where she is trapped into a secret orgy with him and some horny students. Forced to become their sex slave, Yumi's only hope lies in the reluctant Katsutoshi and his perky girlfriend Keiko, who may help her escape her bonds of sexual slavery.
