Yumi is a busty, dark haired beauty who knows how to
give her students what they want. But unfortunately,
she's never been good at getting what she wants and
lately everything seems to be going wrong. First she
has a nasty break-up with her fiance, and then she's
sexually harassed by the Vice-Principal. One thing leads
to another...and before she knows it, the VP and some
very horny students trap her into a hot and heavy orgy.
ravishing her over and over again, they make her swear
to become their secret sex slave. Now, Yumi's only
hope is the reluctant Katsutoshi and his perky girlfriend
Keiko. But even with their help, it'll be hard for
Yumi to escape her bonds of sexual slavery, since
everyone seems to be lusting for the teacher...
