Maria Martinez comes home from a wild night out and finds her big step-sister, Katherine, bound and gagged on the floor. Maria slightly peels the tape off Katherine's mouth to hear what happened. Katherine explains how a bad guy came into the house, took some things, and left her tied up and gagged. At first, Maria is quite overwhelmed by finding her big step-sister in this position, but she also quite like the idea of having Katherine bound, gagged. Maria decides to move on with the idea to keep her big step-sister bound and gagged for the night, but the gag sucks and so does the ties the bad guy put on her, so Maria must now tie and gag her annoying big step-sister even better than the bad guy!
