My Friend Does It Better

Marriage Counselor Sherry, a lesbian, finds an inviting little diner a few miles from her home. The food great and is reasonably priced, and she takes a shine at her young waitress Samantha or Sam. Their friendship blossoms into a closeness that allows the young girl to share her secrets with the older woman. Some of her secrets are of personal and sexual nature. The most current is a dilemma about sex with a boy that she likes, but he has asked her to do an odd thing before they can have any kind of sexual contact.
Sherry, ever the counselor, provides the young Sam with all the advice she needs and more. Even to the point of showing Sam how to kiss and other seductive things. Because Sam is so close to Sherry she takes her to meet the boy of her dreams, Chad, and the cunning boy tries to talk the older woman into threesome. Both Sam and Sherry sidestep the offer but agree to the weird request Chad had made that involves another girl named Randi.
The nervous Sam is taken to Sherry's house and Randi and Sam have a sexual duel to see who will be with Chad. Sam and Randi go at it hot and heavy for the privilege of Chad's company but in the end Sam wonders if he's worth the effort.
