Maria Martinez, bored, engages in self-bondage by stripping naked, stuffing her dirty panties in her mouth, and tapegagging it shut. She wraps duct tape around her ankles and handcuffs her wrists behind her back. Maria enjoys the feeling of being helpless in self-bondage but is interrupted by her older stepsister, Katherine. Katherine wants to stay and play with Maria, so she wraps duct tape around her legs, wrists, and arms. Katherine selfgags herself with duct tape and lies down next to Maria. Stepmother Laura intervenes, wanting to teach her girls a lesson. Laura orders Katherine to strip naked and put her hands behind her back, but Katherine follows orders and gets tied up. Stepmom replaces the tapegag with her own dirty panties and a tight tape wrap gag, making the two naked girls gag kisses. The door opens, demanding that stepmom joins her two naked girls in bondage.
