Mizuhō runs a café and her work and family life are going smoothly. However, she has unconsciously suppressed her own sexual desires due to her busy schedule. One day, she is desired as a woman by Seigo, a new part-time employee, awakening a long-forgotten physical longing. Though she feels guilt about being with a man other than her husband, the overwhelming pleasure of repeated orgasms gradually overtakes her heart. Mizuhō's desires know no limits—she sneaks away from work to meet Seigo, losing herself completely as she desperately craves him. Her heart and body are increasingly drawn to him, stepping onto a new path.
