Rumors tell of a secret service offering exceptionally intense pleasure. Bored with her routine and frustrated by a sexless marriage, Mio Futaba surrenders her entire body from head to toe. Restrained and covered in oil, she grows hotter under the practitioner's sensual touch, writhing and twisting until she loses control. Toys bring her close to passing out, and she finally gives in completely, begging for more and grinding her own hips as she chases the ecstasy her husband cannot provide through one orgasm after another.
