A loving couple visits a massage spa where the treatment rooms are separated by a magic-mirror partition. After an aphrodisiac strips away her self-control, Nano is groped all over and brought to silent orgasm by the male therapist while her unsuspecting boyfriend sits right beside her. She has to bite back every moan as the thrill of cheating takes over. By the end, she is so addicted that she lies to her boyfriend about coming back to 'look prettier' just so the therapist can do it to her again.
