Desc: How to Do Anything at All with Girls: Bob, a public relations man, hires two call girls to help close a contract with a pair of important clients, entrusting his wife with the task of keeping her younger sister and a college friend away from the party. To help the businessmen relax, he invites another couple, muscleman Joe and his wife. Signals immediately begin to get crossed, as the prostitutes mistake Bob for one of his clients. One call girl, an experienced Frenchwoman, leads Bob into the bedroom, while the other indulges her passion for strong bodies by joining Joe in muscle-building exercises. As Joe walks into the shower to cool off, he meets the college friend, who has arrived home early by mistake. Bob's wife, anxious to further her husband's career, allows herself to be seduced by one of the clients, while the other, a shy fellow bored and disgusted with the proceedings, is accosted by Joe's wife, who is determined to get even for her husband's attentions to the prostitute. As the client, aroused, makes his embarrassed escape, he discovers the young sister asleep in another bedroom and rapes her. The party dissolves into an impromptu body-painting session, and the young sister makes a dramatic breakaway from home.
