When the moon is full, the office staff gets full also. Full of sexual drive, that is! The naughty nocturnal highlights include a David Hardman/Heather Lee boff atop a pickup truck; an enthusiastic Christi Lake; Lennox and Shannon Rush getting slurpy in the ladies room (and soaked on the sink); and a hands-off b.j. in the opener. Market this for "Hornymoon" couples.
