(This was originally filmed as a custom video) Your big sister has made you a video for your birthday - what's in it? Oh my god, she's seen your browser history and found out about your obsession for watching videos of girls trying on thongs and shaking their asses... and she's made a video like that for you! You watch in amazement as she shakes, slaps and grabs her fat ass, telling you to jack your cock and cum for her! Just don't tell anyone about this! x
