A couple engaged after a year together visits a bridal spa before their wedding. The tea they are served contains an aphrodisiac, leaving both increasingly aroused during their massages. Through a one-way mirror, the boyfriend watches his beautiful slender girlfriend being fondled and becomes excited himself. A busty female therapist overwhelms him with her technique until he gives in to raw sex. Their reason collapses, and both partners surrender to pleasure as they are taken at the same time.
