Your sister is a brat who's used to getting what she wants, so when she asks you if she can study in the living room while you're watching TV you of course tell her it's okay. She's somehow oblivious to the fact that you can completely see up her short nightgown while she's on the couch with you. At first she ignores you while she studies but keeps catching you looking over at her, she questions you why as to why you keep staring at her, you tell her that you think her slippers are cute. Convinced you were checking out her feet, she tells you that you can look at her feet all you want as long as you rub them for her, you accept and take the opportunity to get an even better view of her pussy now that you're right between her legs. She continues being her bratty self while you rub her feet so you confess that you tricked her and got the better of her for once. You had no interest in her feet and just wanted to look at her pussy.
