Stepsister's feet in bath

You have such a crush on your stepsister! Her body is a body of a goddess, that ass and oh my god those arches of her feet. She's just preparing to take a bath and you are watchin her, starring at her feet and ass wishing you could take the bath with her and worship her feet all the time. She sees you in the mirror and instead of screaming and swearing she smiles at you like she already knew you have a crush on her. Than she starts to slowly getting into the bath, one foot gets wet and the other and you just can't take your eyes of her. "So what are you waiting for? Come closer if you like my feet so much. I need you to wash them.".
