Jodie Johnson is pleased that his stepsister Gigi Sweets is helping him with his chores. They do the dishes together, but when Gigi gets nice and close to him Jodie runs away to try to hide his hardon. Later, they watch a movie together but Jodie pops a boner just looking at Gigi. Later still, Gigi calls Jodie in to have him help her tie her dress.

When Jodie tries once again to leave the situation because his body is reacting, Gigi confronts him. She knows he's reacting to The Girls, so she offers to let him have a peek at them. Then she insists that if Jodie is going to masturbate, he stay because it'd be hot. Soon, Jodie has permission to touch Gigi's boobs. Then she's on her knees giving him a titty fuck and blowing his dick.

It's such an easy thing for Gigi to crawl towards Jodie's face so he can suckle her tits while she rides his dick. Then Jodie gets to enjoy watching those big ones jiggle as he bangs Gigi while she lays on her back. They spoon together with Jodie keeping Gigi's pussy party going, and then she finishes him off by riding him in reverse cowgirl. As Gigi collapses filled with a nice creampie, she comments that Jodie will enjoy having a stepsister with big boobs.
