Husband's fantasy comes to life when his eager wife, Olive Glass, invites her naive secretary, Rebecca Vanguard, for a "training session" in the office after hours. Little does the innocent intern know, she's about to be the filling in a taboo sandwich. Olive, a sultry vixen, starts by teaching Rebecca how to pleasure a man, using husband Stirling Cooper's throbbing cock as a demonstration tool. As they kiss and caress each other, Rebecca's inhibitions melt away, revealing a hungry little minx beneath. The camera captures their every move, hidden but unblinking, as the trio explores each other's bodies, the sound of wet, eager moans echoing through the empty office.
