Chizuru Sendou, 43, married her college classmate after a surprise pregnancy 13 years ago. Looking back, she suspects that the pregnancy might have been his calculated move to secure marriage. At the time, Chizuru was extremely popular and receiving advances from multiple men. She and her husband weren't in a romantic relationship—just drinking buddies who ended up sleeping together once, leading to the unplanned marriage. That possibility can't be dismissed. Still, since her husband deeply cherishes both her and their child, she now feels it all worked out for the best. So why did she decide to enter adult videos? In recent years, due to his busy schedule, their sex life became unsatisfying, and she eventually reached her limit. Not wanting to blame her husband who works hard for the family, she shyly admits, "I just couldn't hold back anymore." To fulfill Chizuru's desires, her debut work in the First-Time Filmed Married Woman Documentary series has finally been realized.
