Sayaka Koike is 38 years old. She lives with her husband, who is an office worker, and her son, who is a Sayaka. She used to work as a scuba diving instructor, where she met and married her husband. She quit her job as an instructor after giving birth, but she still goes diving once every six months. As for her sex life, she has sex with her husband maybe once a month, which is lonely, but she has a sex friend who she has sex with about five times a month, so they are quite active. This time, she came to Tokyo to accompany Sayaka husband on a business trip. "I've always been interested in AV, but I thought I couldn't miss this chance (laughs)." We promise you will enjoy it even more than Sayaka expected, so please look forward to it!
