"I like the 'matsuba kuzushi' position. That shape stimulates my G-spot the most." Masaki Rieko, 48, a full-time housewife. This year marks her 26th year of marriage with her husband and their three children, making them a family of five. Their marital relationship is currently good, and they have sex about once or twice a week, but Rieko seems completely unsatisfied. "He might not mean it this way, but sex with my husband is like a regular ritual to confirm our marital bond… There's no intense passion like 'Let's both enjoy ourselves thoroughly today!' Maybe it's just because we're getting older…" The quality of sex has clearly changed since they first met. "I still remember how good it felt the first time I had a vaginal orgasm." She wants to indulge in pleasure like she did on that day when she first experienced true bliss. With this thought in her heart, Rieko begins her first extramarital experience.
