Mitsuki Enomoto, who turns 60 this year, married her sincere and hardworking boss 30 years ago and has been living a long, stable married life. Her husband is socially reserved and struggles with interpersonal relationships, but excels in bed—formerly having sex 3 to 4 times a week. Although frequency has decreased with age, they still enjoy sex regularly, 1 to 2 times per week. Traveling is their shared hobby, and they go on trips every two months. These getaways refresh both their bodies and minds, further boosting their sexual desire.
