A home visit service advertised as a "lactation massage." Normally handled by female staff, the service is strangely assigned to a male therapist. He uses strong, masculine techniques to stimulate milk production, making mysterious claims about its effectiveness. His suggestive words and powerful hands gradually lure young married women into an erotic situation. Stripped naked, they begin to squirt breast milk in a surreal, dreamlike scene. The intense sensual stimulation ultimately drives them to the edge, leaving them thoroughly fucked.
