The fourth installment in the popular series, in which unsuspecting women who visit a beauty salon are trapped in a drug-induced scheme, features a married woman. During the treatment, aphrodisiacs mixed into the oils and steamer make her body flush and become highly sensitive. Her throbbing vagina then climaxes with a powerful arching of her back, squirting profusely. This expanded version also includes a female masseuse who is tricked by having an aphrodisiac hidden in her mask, bringing the total to four women.
