Father Figure.

A grieving family starts blurring the lines between platonic love and lust. Linda and her 18-year old step-daughter Sam talk about the man of the house, who has passed away, leaving Sam and Linda financially destitute. They are thankful that Uncle Jerry, the man's step-brother, will be coming to stay with them to help them. Harold and Martha Green reveal to her daughter Cassie for her 18th birthday, that she was swapped at birth as part of an arrangement with a friends couple, so that each couple could indulge their fantasy and fuck their 'daughter' when she came of age. Cassie's sister Heidi reveals also that she has been through the same thing.
