Kamina Hitomi, 46 years old. Her figure is a perfect T158, B88 (E cup), W58, H86. With her elegant facial features, Hitomi lives with her husband as little more than a roommate. Their relationship is so distant that she can't even recall the last time they had sex. But she harbors a secret—right before her period, she becomes overwhelmingly aroused and craves masturbation. And today might just be that day.
