Couples struggling with sex visit a clinic rumored to restore happiness. A male counselor first explains how to build deeper intimacy, then places each woman on the examination table and demonstrates his advice personally. The male partners become secretly aroused watching their women taken before their eyes, while the women move from confusion to wild orgasms under the counselor's unexpected technique. The officially approved NTR session makes each couple confront their partner more intensely and recognize the desires hidden beneath their relationship.
