Married woman SEX counseling

We've been married for 10 years. Chiyuki and her husband still love each other, but they no longer spend their nights together. One day, her husband consults with Oki, a counselor, and Chiyuki ends up opening up about her marital life. As part of the treatment, Chiyuki is blindfolded and asked questions by her husband. Chiyuki gradually begins to feel her body being touched, but it turns out that it was Oki, not her husband, who was touching her body... Although they were hesitant about such exciting treatment, changes began to appear in their hearts...
