It's early evening and Maria Martinez is wearing pajamas when she walks in to find her big step-sister Katherine doing her make-up all dressed up in a beautiful yellow dress. Maria is curious to know what Katherine is up to and is shown the dating profile of a really hot guy Katherine is about to go on a date with tonight.

Maria is so jealous of her big step-sister that she decides to overpower her and take her place on the date tonight! Maria attacks Katherine with a handgag from behind and manages to get herself into the chair to sit behind Katherine.

Katherine desperately tries to fight off her jealous little step-sister but her struggles are futile. With her legs wrapped around Katherine's body, Maria turns the silencing hand gagging into a nice handsmother which makes her big step-sister fall resting!

When we return to the scene, we see napping Katherine duct-taped to the chair and stripped down to her underwear. She slowly wakes up and notices Maria standing next to her while changing from her pajamas to the beautiful yellow dress her chair-tied big step-sister wore just a few minutes ago!

Katherine complains about being tied up while made to look at provoking Maria demonstratively putting on her dress so Maria shuts her up with a handgag followed by the insertion of a soft orange rubber ball stuffed inside her whining step-sister's whining mouth!

Maria grabs a roll of transparent packaging tape and wraps the rubber ball inside Katherine's mouth, making her a nice and tight wrap-around gag to keep the ball in place. Maria then sits down next to Katherine and starts putting on make-up!

Katherine gag talks at her provoking little step-sister who doesn't seem to give a damn about whatever she is trying to say. Maria slowly finishes her make-up and when she is just about ready to go, she takes a couple of selfies with her bound, gagged and humiliated big step-sister!

Katherine is finally left tied up and helpless at home while Maria is ready to steal her big step-sister's hot date in her stolen dress! What a bitch!
