To walk the path of a high-class SM prostitute, young wife Aya harbored intense masochistic desires. Unfulfilled by sex with her husband, she began working at a secret club for just a few hours each day. Under the strict guidance and training of the manager, she became a favorite of a wealthy young client, receiving repeated requests that gradually sparked special feelings within her. Through deep-throat instruction, standing dildo cowgirl practice, serving by using her toes to guide his cock into her mouth, and being whipped from behind with a single whip, her masochistic nature blossomed more and more.
