"My ideal sex is when we're in a tight fist and trying to get the upper hand," says Akina Nagahara, 48. She works at a call center and is a mother of two. She leads a busy life with work, housework, and childcare, but even now, after 14 years of marriage, she still gets her energy from sex, which she continues to have twice a week. However, since her eldest son reached adolescence, she has changed to a quick and easy style of sex out of consideration for her son. It has become a far cry from the passionate lovemaking that was her source of energy. The frustration that has built up over the years of unfulfilled days and the sense of crisis as a woman led her to decide to appear in an adult video. Watch as this wife, hungry for some quality time, instinctively performs a voluptuous cowgirl position.
