Eliza Starr comes home late and admits to her stepmother, Sierra Lovelea, that she failed her chemistry test. Angered, Sierra arranges for Eliza to retake the test but is further incensed when she discovers Eliza has been using her panties. Sierra decides to punish Eliza by tying her hands with duct tape, gagging her with the used panties and medical tape, and then spanking her over her knee while giving her a wedgie. Eliza is left helplessly enduring the punishment, gagged and unable to protest effectively, until her stepfather returns home.
