Relaxing beside her husband, the wife gradually lets her guard down as the masseur's hands touch her body.

Even as her husband remains nearby, she becomes trapped in a relationship she can't escape. She never imagined she could be so easily seduced. In the relaxed atmosphere, surrendering her body brings overwhelming pleasure—and beneath it all lies the vulnerable, defenseless figure of a wife.
