Lucy is your step-sister, she has been stood up by her boyfriend and she is annoyed because she got dressed up to go out. You can't help but admire her long legs in the small black skirt she is wearing and it doesn't take your cock long to start responding to the sight in front of you, Lucy catches you looking and decides the best way to get back at her boyfriend is to let you look up her skirt and wank while she teases you.
