Isabel Moon has been sending nude selfies of herself, but things have escalated and now she needs her stepbrother's help. She needs full-body shots and agrees to give her bro some of the money she earns if he helps her out. Isabel promises not to tell anyone, but the next day she needs more help. The guy who bought the pictures doesn't just want more posed nudes, he wants pics of Isabel sucking dick. She has decided her stepbrother will be the cock model and she'll say or do whatever it takes to make it happen.

Eventually Isabel's stepbrother agrees to help her out despite his reservations. He takes off his pants and next thing he knows his stepsis's lips are wrapped around his fuck stick as she deep throats him and gargles his balls. As Isabel's bro realizes that his girlfriend barely gives him blowjobs, he's seduced by Isabel's total abandon in the sack. When she suggests that he put it inside, he can't resist the urge. His crazy stepsis is just as nuts in the sack as she moans her way to a climax whiel he fucks her.

Hopping on top for a stiffie ride, Isabel makes it clear she's still the one in charge. She falls to her back so her bro can keep on pounding that pussy to the tune of her gasps and moans. Then she gets on her hands and knees and jerks her hips in time to her stepbrother's thrusts as he bangs her from behind. When her brother is finally ready to cum, Isabel makes sure to get a facial so she can get a pic of her cum-covered face smiling and licking her lips.
