They have waited a long time to be together, and finally their dream has come true, as both Olivia and Greg enjoy their worldly evening with a mixture soap and suds, and fulfillment that cleansed their misery.
They knew what they were doing was wrong; both Greg and Olivia were married to people that never made them happy.
They knew the consequences, but they were willing to risk it, if it meant that Greg will lose his business to an overly-ambitious wife. They knew the risk if meant Olivia had to face her jealous, insecure husband.
Their passion for each other was way beyond the danger. They were bathing each other with affection and bliss. For the first time in their lives, their hearts felt safe at a motel room 120 miles away from home.
