Maya Bijou has a real love/hate relationship with her brother Lucas Frost. When Maya discovers that Lucas is adopted, she can't wait to tell him. Lucas thinks it's a prank, but his mom, Dava Foxx, winds up confirming it even though she's distracted by the phone. That gives Lucas an idea. He's had a crush on Maya for ages and thinks she's super hot. Now he has the ability to act on his fantasies.
Lucas waits until Maya is in the middle of changing before he walks in on her. Maya tells him to get out, but then changes her tune as she decides instead to fuck with Lucas. She pops her boobs out to jiggle them in Lucas's face, then flashes her ass and twat to him. Maya thinks she has the upper hand, but Lucas takes her up on her invitation to shove his dick inside. She freaks out when he does, but then decides Lucas's cock feels really good and she wants to see where this goes.
The adopted siblings enjoy doggy style for a bit, but then Maya takes a short break to enjoy sucking Lucas off. Since Lucas is already on his back, Maya hops on to ride that fuck stick. Lucas reverses their positions, banging Maya as her titties bounce with every stroke until he can't wait another moment. Lucas has just splooged all over Maya's stomach when Dava walks in on them naked and flips out.
