Alina starts making moves on Rion. He tries to disengage, but his stepsister is hot and he is inevitably turned on. As soon as Alina notices, she moves on from playing with her own twat and titties to whipping out his fuck stick and sucking him off. Rion can't believe that his sexy stepsis is really willing to get it on with him, so when Alina turns around and waves her ass in an invitation to do a doggy style pussy pounding he's quick to take her up on it. They move on to Alina riding Rion's stiffie while he palms her ass with his big hands. She leans forward so he can play with her titties, then falls onto her back so he can really dominate her tight little body. When Rion has pulled out to cum on Alina's boobs, he tries to suggest that they get back to studying. Alina lets him know that he'll be doing her homework lest she tell her mom that he's been coming on to her.
