It's always strange at your girlfriend's parent's place for the first time. Typically it consists of sexless nights, early jogs, and "including" yourself. Upon your arrival, Pamela's parents were very clear that you were to in separate rooms. The two of you have been here a week now and have hardly touched each other, but tonight, Mr. and Mrs. Morrison have gone to bed early. Sounds like a window of opportunity to me. When Pamela crawls onto your bed and begins sucking your cock and mounting you, be sure to keep a tight lid on yourself because if her parents wake up, you're fucked.
