Forbidden Fruit

Your step-mum is angry with you because you haven't made your bed yet again! But you tell her that you don't know how to make a bed, so she's going to show you! As she's showing you, she wants you to pay close attention, but all you're concentrating on is up her skirt! Beth is outraged when she catches you perving on her, but you tell her she's like forbidden fruit and that the only solution is for you to wank your cock over her to get it out of your system!
