Riley Shae Caught Masturbating

Mike catches his step-sister, Riley Shae, masturbating on their parents bed, but she does not feel embarrassed at all. That horny brunette invites him to join her, so she jerks him off while he is sensually touching her wet pussy. Riley wants to see her step-brother cumming but she takes her time with him. "No one should ever know about this, OK Mike?"
