Your sister walks in and says she has an itch you need to help her with. She stand over your bed and spreads her legs. She shows you her pussy and says come on bro fuck me. I need it. I need some cum inside me. I am aiching for it. Please. In a weird way this turns you on. You push away the blanket and show her your dick. She attacks like a hungry kitten. She wasn’t kidding. Bad sister!!
