30-year-old Kazuki is a lonely woman who loves children. Now five years into her marriage, she's only been with two men in her life—her husband and one other partner—and she regrets not having more experiences with different people.
Since her youth, she's been aware of men, and after being taught adult techniques by a 10-year-older boyfriend during her school days, she gradually became more sexually awakened. After dates, and even just from a man's touch, her body instinctively writhes with heightened sensitivity.
With a dazed, dreamy gaze, she thoroughly licks the shaft, balls, and even the anus. Her body is extremely responsive, and when switching from missionary to doggystyle, she begins moving as if completely entranced.
Like a toy, her perfectly round ass takes rapid, hard piston thrusts, making her cry out, "I'm coming—gonna come!" In the end, her body arches into a tight bow as she climaxes in a stunning, climactic finish.
