Jennifer Roams parts one and two combined:

Jennifer and Paul meet her first year at university. An innocent misunderstand leads to Paul witnessing Jennifer with another man. When Paul loves it as much as Jen, they realize they share a common joy and take the first tentative steps towards exploration and understanding. Travel with them as they move through life, growing and learning, discovering ever greater intimacy and excitement. Many surprises await our young lovers, including Jennifer and her little sister Tina becoming closer than ever before.

Jennifer and Paul, finally husband and wife, graduate from college and begin their lives together. On the outside they are a perfect American couple, but we know their secrets and their powerful desires. Driven by her own lusts and her husband's encouragement, Jennifer chases her every desire, including the ultimate taboo, and they must both learn and evolve or be crushed by them.
