Secret Sins (2006)

Kristen (Michelle Lay) and Sean (Randy Spears) are a married couple who work together as licensed marriage counselors, using the therapy sessions to keep their own relationship spicy. New clients Valerie (Chloe Morgan) and Brad (Sean Juergens) are a married couple who don’t have any big problems, but want to improve their relationship. The counselors guide the couple through a sexual and relationship therapy session, discussing various topics and using stories about previous clients as examples. Kristen takes Valerie aside so that she can explore her desire to try sex with another female, and the couple later try to decide if they’re ready to try a threesome.
