Yuki Takizawa is 55 years old and a mother of one. She was so devoted to her child that she would even say that raising her child was her hobby. However, when her beloved son became independent, she started attending a dance school, which marked a major turning point in her life. "As I was pressed up against a man and he put his hands around my waist, I gradually began to think of him as a member of the opposite sex..." She betrayed her beloved husband and experienced the taste of infidelity for the first time. She was hooked on the sense of immorality and the extraordinary stimulation that she could not feel during the monthly obligatory sex with her husband. "I feel sorry for my husband, but I want to have more sex. I can feel my libido increasing at this age," Yuki says forcefully, as her powerful hips, trained through dance, explode!
