She makes a bet with Kyle that he'll never graduate and says that she'll fuck him if he does. Three years later, Kyle has earned his degree and he's ready to get what his stepsis has promised. Kenzie has conveniently forgotten their bet, but eventually Kyle coaxes her into making him cum with a handie. When he whips out his dick, Kenzie agrees to start stroking.She may not want to admit it, but Kenzie likes the thickness of her brother's big dick. When Kyle doesn't cum right away, he urges Kenzie to start sucking him off. It takes less work this time before he gets to feel his stepsis's hot lips around his big member. Even Kenzie's deep throat cock gobbling doesn't get Kyle off, though, so he lets her know that he's going to have to fuck her so he can cum like she promised. Kenzie agrees to let him bang her doggy style.Kenzie pretended not to be into it at first, but now that she's got Kyle's big stiffie inside her she loves it! Kyle pounds her from behind until he makes his stepsis squeal. Then he sits on the couch so she can ride his cock as her titties jiggle in his face. Turning around, Kenzie lets Kyle enjoy her hot butt as she keeps on riding him. When she lays back on the couch with her thigh spread, Kenzie watches as Kyle bangs her until he's on the verge of cumming. He pulls out at the last minute, covering his stepsis in jizz just as he was promised.
