Gorgeous Dr. Sarah Shevon is examining her new patient, big-assed beauty Sierra Sanders, who wants to improve her anal health. This 'Doctor of Assology' sinks her fingers inside Sierra's tender asshole, rims her patient's pucker and drills Sierra's greasy backdoor using a big dildo. Well-hung Jordan Ash arrives and fucks Sierra's lovely face; Sarah strips, then joins in for a slobbery double-blow job. Sierra rides Jordan's huge shaft and Sarah makes her colon bloom out in a red, glistening anal prolapse! When both girls have been thoroughly butt-fucked and have sucked Jordan's cock ass-to-mouth, they orally swap his sperm.
