The stepdaughter of his father's new wife is an incredibly lewd little devil who teases his father and brothers with her panty shots. When she goes to clean her brothers' room and finds a porn magazine, the brothers are so excited by the sight of her engrossed in reading it with her underwear completely visible that they can't help but make a move. As if that was what she had intended, the lewd little sister happily licks and sucks the two overly erect dicks in turn. She wants to be fucked by both dicks at the same time, so an incestuous threesome breaks out!
