You enter your room after school to find your step-sister sitting on the edge of your bed. She shouldn't be home this early, but she is and you don't question it. She's hot, and ever since she and her dad moved into your house last year you've found yourself fantasizing about fucking her on numerous occasions. You jack off to her each night before you go to bed, and each morning you wake up to the little tease in her short nighty and cotton panties. You never see the full thing, just little nipples poking through fabric and the small bulge of her pussy poking out when she bends over to get milk from the fridge. Now she's sitting in your bed, propositioning you. What will you do? She tells you she has a secret to share, that she knows your secret and wants you to masturbate to her... but you have to close your eyes. Her secret is one that's better to be surprised with! Eventually, as she instructs you to jerk your cock, you take a peek. And there you see it... your sister has a giant cock! When she realizes you're looking, she tells you all about how she got that cock, where she really came from, and what she really is there for. Watch the video to find out the rest of the story ;) -B
