Due to restrictions on going out, Nanami Sakiko, a 41-year-old housewife and mother of one with 16 years of marriage behind her, has been limited to just once-a-month sex with her husband. Standing 160cm tall with a stunning G-cup figure, she clearly separates her sexual experiences: sex with her husband is an expression of love, while sex with other men fulfills a different, purely physical desire. She admits that she cannot fully let go with her husband, and believes cheating allows her to express her true sexual desires and hidden kinks. However, because of the ongoing self-restraint measures, she hasn't been able to meet her affair partners for over two months—the longest dry spell since her teens. This summer, her pent-up lust is about to explode in an "Ultra Fest." While many value family time more than ever, all eyes are on how Sakiko will unleash her desires this season.
